Plugins can add new token\ntypes and new tokenizer contexts (if necessary), and extend methods in\nthe parser object. This is not a clean, elegant API—using it requires\nan understanding of Acorn's internals, and plugins are likely to break\nwhenever those internals are significantly changed. But still, it is\n_possible_, in this way, to create parsers for JavaScript dialects\nwithout forking all of Acorn. And in principle it is even possible to\ncombine such plugins, so that if you have, for example, a plugin for\nparsing types and a plugin for parsing JSX-style XML literals, you\ncould load them both and parse code with both JSX tags and types.\n\nA plugin is a function from a parser class to an extended parser\nclass. Plugins can be used by simply applying them to the `Parser`\nclass (or a version of that already extended by another plugin). But\nbecause that gets a little awkward, syntactically, when you are using\nmultiple plugins, the static method `Parser.extend` can be called with\nany number of plugin values as arguments to create a `Parser` class\nextended by all those plugins. You'll usually want to create such an\nextended class only once, and then repeatedly call `parse` on it, to\navoid needlessly confusing the JavaScript engine's optimizer.\n\n```javascript\nconst {Parser} = require(\"acorn\")\n\nconst MyParser = Parser.extend(\n  require(\"acorn-jsx\")(),\n  require(\"acorn-bigint\")\n)\nconsole.log(MyParser.parse(\"// Some bigint + JSX code\"))\n```\n\nPlugins override methods in their new parser class to implement\nadditional functionality. It is recommended for a plugin package to\nexport its plugin function as its default value or, if it takes\nconfiguration parameters, to export a constructor function that\ncreates the plugin function.\n\nThis is what a trivial plugin, which adds a bit of code to the\n`readToken` method, might look like:\n\n```javascript\nmodule.exports = function noisyReadToken(Parser) {\n  return class extends Parser {\n    readToken(code) {\n      console.log(\"Reading a token!\")\n      super.readToken(code)\n    }\n  }\n}\n```\n"

    "content": "# Acorn\n\nA tiny, fast JavaScript parser written in JavaScript.\n\n## Community\n\nAcorn is open source software released under an\n[MIT license](https://github.com/acornjs/acorn/blob/master/acorn/LICENSE).\n\nYou are welcome to\n[report bugs](https://github.com/acornjs/acorn/issues) or create pull\nrequests on [github](https://github.com/acornjs/acorn).\n\n## Installation\n\nThe easiest way to install acorn is from [`npm`](https://www.npmjs.com/):\n\n```sh\nnpm install acorn\n```\n\nAlternately, you can download the source and build acorn yourself:\n\n```sh\ngit clone https://github.com/acornjs/acorn.git\ncd acorn\nnpm install\n```\n## Importing acorn\n\nESM as well as CommonJS is supported for all 3: `acorn`, `acorn-walk` and `acorn-loose`.\n\nESM example for `acorn`:\n\n```js\nimport * as acorn from \"acorn\"\n```\n\nCommonJS example for `acorn`:\n\n```js\nlet acorn = require(\"acorn\")\n```\n\nESM is preferred, as it allows better editor auto-completions by offering TypeScript support.\nFor this reason, following examples will use ESM imports.\n\n## Interface\n\n**parse**`(input, options)` is the main interface to the library. The\n`input` parameter is a string, `options` must be an object setting\nsome of the options listed below. The return value will be an abstract\nsyntax tree object as specified by the [ESTree\nspec](https://github.com/estree/estree).\n\n```javascript\nimport * as acorn from \"acorn\"\nconsole.log(acorn.parse(\"1 + 1\", {ecmaVersion: 2020}))\n```\n\nWhen encountering a syntax error, the parser will raise a\n`SyntaxError` object with a meaningful message. The error object will\nhave a `pos` property that indicates the string offset at which the\nerror occurred, and a `loc` object that contains a `{line, column}`\nobject referring to that same position.\n\nOptions are provided by in a second argument, which should be an\nobject containing any of these fields (only `ecmaVersion` is\nrequired):\n\n- **ecmaVersion**: Indicates the ECMAScript version to parse. Can be a\n  number, either in year (`2022`) or plain version number (`6`) form,\n  or `\"latest\"` (the latest the library supports). This influences\n  support for strict mode, the set of reserved words, and support for\n  new syntax features.\n\n  **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being\n  implemented by Acorn. Other proposed new features must be\n  implemented through plugins.\n\n- **sourceType**: Indicate the mode the code should be parsed in. Can be\n  either `\"script\"`, `\"module\"` or `\"commonjs\"`. This influences global strict mode\n  and parsing of `import` and `export` declarations.\n\n  **NOTE**: If set to `\"module\"`, then static `import` / `export` syntax\n  will be valid, even if `ecmaVersion` is less than 6. If set to `\"commonjs\"`,\n  it is the same as `\"script\"` except that the top-level scope behaves like a function.\n\n- **onInsertedSemicolon**: If given a callback, that callback will be\n  called whenever a missing semicolon is inserted by the parser. The\n  callback will be given the character offset of the point where the\n  semicolon is inserted as argument, and if `locations` is on, also a\n  `{line, column}` object representing this position.\n\n- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing\n  commas.\n\n- **allowReserved**: If `false`, using a reserved word will generate\n  an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher\n  versions. When given the value `\"never\"`, reserved words and\n  keywords can also not be used as property names (as in Internet\n  Explorer's old parser).\n\n- **allowReturnOutsideFunction**: By default, a return statement at\n  the top level raises an error. Set this to `true` to accept such\n  code.\n\n- **allowImportExportEverywhere**: By default, `import` and `export`\n  declarations can only appear at a program's top level. Setting this\n  option to `true` allows them anywhere where a statement is allowed,\n  and also allows `import.meta` expressions to appear in scripts\n  (when `sourceType` is not `\"module\"`).\n\n- **allowAwaitOutsideFunction**: If `false`, `await` expressions can\n  only appear inside `async` functions. Defaults to `true` in modules\n  for `ecmaVersion` 2022 and later, `false` for lower versions.\n  Setting this option to `true` allows to have top-level `await`\n  expressions. They are still not allowed in non-`async` functions,\n  though. Setting this option to `true` is not allowed when `sourceType: \"commonjs\"`.\n\n- **allowSuperOutsideMethod**: By default, `super` outside a method\n  raises an error. Set this to `true` to accept such code.\n\n- **allowHashBang**: When this is enabled, if the code starts with the\n  characters `#!` (as in a shellscript), the first line will be\n  treated as a comment. Defaults to true when `ecmaVersion` >= 2023.\n\n- **checkPrivateFields**: By default, the parser will verify that\n  private properties are only used in places where they are valid and\n  have been declared. Set this to false to turn such checks off.\n\n- **locations**: When `true`, each node has a `loc` object attached\n  with `start` and `end` subobjects, each of which contains the\n  one-based line and zero-based column numbers in `{line, column}`\n  form. Default is `false`.\n\n- **onToken**: If a function is passed for this option, each found\n  token will be passed in same format as tokens returned from\n  `tokenizer().getToken()`.\n\n  If array is passed, each found token is pushed to it.\n\n  Note that you are not allowed to call the parser from the\n  callback—that will corrupt its internal state.\n\n- **onComment**: If a function is passed for this option, whenever a\n  comment is encountered the function will be called with the\n  following parameters:\n\n  - `block`: `true` if the comment is a block comment, false if it\n    is a line comment.\n  - `text`: The content of the comment.\n  - `start`: Character offset of the start of the comment.\n  - `end`: Character offset of the end of the comment.\n\n  When the `locations` options is on, the `{line, column}` locations\n  of the comment’s start and end are passed as two additional\n  parameters.\n\n  If array is passed for this option, each found comment is pushed\n  to it as object in Esprima format:\n\n  ```javascript\n  {\n    \"type\": \"Line\" | \"Block\",\n    \"value\": \"comment text\",\n    \"start\": Number,\n    \"end\": Number,\n    // If `locations` option is on:\n    \"loc\": {\n      \"start\": {line: Number, column: Number}\n      \"end\": {line: Number, column: Number}\n    },\n    // If `ranges` option is on:\n    \"range\": [Number, Number]\n  }\n  ```\n\n  Note that you are not allowed to call the parser from the\n  callback—that will corrupt its internal state.\n\n- **ranges**: Nodes have their start and end characters offsets\n  recorded in `start` and `end` properties (directly on the node,\n  rather than the `loc` object, which holds line/column data. To also\n  add a\n  [semi-standardized](https://bugzilla.mozilla.org/show_bug.cgi?id=745678)\n  `range` property holding a `[start, end]` array with the same\n  numbers, set the `ranges` option to `true`.\n\n- **program**: It is possible to parse multiple files into a single\n  AST by passing the tree produced by parsing the first file as the\n  `program` option in subsequent parses. This will add the toplevel\n  forms of the parsed file to the \"Program\" (top) node of an existing\n  parse tree.\n\n- **sourceFile**: When the `locations` option is `true`, you can pass\n  this option to add a `source` attribute in every node’s `loc`\n  object. Note that the contents of this option are not examined or\n  processed in any way; you are free to use whatever format you\n  choose.\n\n- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property\n  will be added (regardless of the `location` option) directly to the\n  nodes, rather than the `loc` object.\n\n- **preserveParens**: If this option is `true`, parenthesized expressions\n  are represented by (non-standard) `ParenthesizedExpression` nodes\n  that have a single `expression` property containing the expression\n  inside parentheses.\n\n**parseExpressionAt**`(input, offset, options)` will parse a single\nexpression in a string, and return its AST. It will not complain if\nthere is more of the string left after the expression.\n\n**tokenizer**`(input, options)` returns an object with a `getToken`\nmethod that can be called repeatedly to get the next token, a `{start,\nend, type, value}` object (with added `loc` property when the\n`locations` option is enabled and `range` property when the `ranges`\noption is enabled). When the token's type is `tokTypes.eof`, you\nshould stop calling the method, since it will keep returning that same\ntoken forever.\n\nNote that tokenizing JavaScript without parsing it is, in modern\nversions of the language, not really possible due to the way syntax is\noverloaded in ways that can only be disambiguated by the parse\ncontext. This package applies a bunch of heuristics to try and do a\nreasonable job, but you are advised to use `parse` with the `onToken`\noption instead of this.\n\nIn ES6 environment, returned result can be used as any other\nprotocol-compliant iterable:\n\n```javascript\nfor (let token of acorn.tokenizer(str)) {\n  // iterate over the tokens\n}\n\n// transform code to array of tokens:\nvar tokens = [...acorn.tokenizer(str)]\n```\n\n**tokTypes** holds an object mapping names to the token type objects\nthat end up in the `type` properties of tokens.\n\n**getLineInfo**`(input, offset)` can be used to get a `{line,\ncolumn}` object for a given program string and offset.\n\n### The `Parser` class\n\nInstances of the **`Parser`** class contain all the state and logic\nthat drives a parse. It has static methods `parse`,\n`parseExpressionAt`, and `tokenizer` that match the top-level\nfunctions by the same name.\n\nWhen extending the parser with plugins, you need to call these methods\non the extended version of the class. To extend a parser with plugins,\nyou can use its static `extend` method.\n\n```javascript\nvar acorn = require(\"acorn\")\nvar jsx = require(\"acorn-jsx\")\nvar JSXParser = acorn.Parser.extend(jsx())\nJSXParser.parse(\"foo(<bar/>)\", {ecmaVersion: 2020})\n```\n\nThe `extend` method takes any number of plugin values, and returns a\nnew `Parser` class that includes the extra parser logic provided by\nthe plugins.\n\n## Command line interface\n\nThe `bin/acorn` utility can be used to parse a file from the command\nline. It accepts as arguments its input file and the following\noptions:\n\n- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version\n  to parse. Default is version 9.\n\n- `--module`: Sets the parsing mode to `\"module\"`. Is set to `\"script\"` otherwise.\n\n- `--locations`: Attaches a \"loc\" object to each node with \"start\" and\n  \"end\" subobjects, each of which contains the one-based line and\n  zero-based column numbers in `{line, column}` form.\n\n- `--allow-hash-bang`: If the code starts with the characters #! (as\n  in a shellscript), the first line will be treated as a comment.\n\n- `--allow-await-outside-function`: Allows top-level `await` expressions.\n  See the `allowAwaitOutsideFunction` option for more information.\n\n- `--compact`: No whitespace is used in the AST output.\n\n- `--silent`: Do not output the AST, just return the exit status.\n\n- `--help`: Print the usage information and quit.\n\nThe utility spits out the syntax tree as JSON data.\n\n## Existing plugins\n\n - [`acorn-jsx`](https://github.com/RReverser/acorn-jsx): Parse [Facebook JSX syntax extensions](https://github.com/facebook/jsx)\n"

    "content": "# Acorn loose parser\n\nAn error-tolerant JavaScript parser written in JavaScript.\n\nThis parser will parse _any_ text into an\n[ESTree](https://github.com/estree/estree) syntax tree that is a\nreasonable approximation of what it might mean as a JavaScript\nprogram.\n\nIt will, to recover from missing brackets, treat whitespace as\nsignificant, which has the downside that it might mis-parse a valid\nbut weirdly indented file. It is recommended to always try a parse\nwith the regular `acorn` parser first, and only fall back to this\nparser when that one finds syntax errors.\n\n## Community\n\nAcorn is open source software released under an\n[MIT license](https://github.com/acornjs/acorn/blob/master/acorn-loose/LICENSE).\n\nYou are welcome to [report\nbugs](https://github.com/acornjs/acorn/issues) or create pull requests\non [github](https://github.com/acornjs/acorn).\n\n## Installation\n\nThe easiest way to install acorn-loose is from [`npm`](https://www.npmjs.com/):\n\n```sh\nnpm install acorn-loose\n```\n\nAlternately, you can download the source and build acorn yourself:\n\n```sh\ngit clone https://github.com/acornjs/acorn.git\ncd acorn\nnpm install\n```\n\n## Interface\n\n**parse**`(input, options)` takes an input string and a set of options\n(the same options as\n[acorn](https://github.com/acornjs/acorn/blob/master/acorn/README.md)\ntakes), and returns a syntax tree, even if the code isn't\nsyntactically valid. It'll insert identifier nodes with name `\"✖\"` as\nplaceholders in places where it can't make sense of the input. Depends\non the `acorn` package, because it uses the same tokenizer.\n\n```javascript\nimport * as acornLoose from \"acorn-loose\"\nconsole.log(acornLoose.parse(\"1 / * 4 )[2]\", {ecmaVersion: 2020}))\n```\n\nLike the regular parser, the loose parser supports plugins. You can\ntake the **`LooseParser`** class exported by the module, and call its\nstatic `extend` method with one or more plugins to get a customized\nparser class. The class has a static `parse` method that acts like the\ntop-level `parse` method.\n\n**isDummy**`(node)` takes a `Node` and returns `true` if it is a dummy node\ninserted by the parser. The function performs a simple equality check on the\nnode's name.\n"

    "content": "# Acorn AST walker\n\nAn abstract syntax tree walker for the\n[ESTree](https://github.com/estree/estree) format.\n\n## Community\n\nAcorn is open source software released under an\n[MIT license](https://github.com/acornjs/acorn/blob/master/acorn-walk/LICENSE).\n\nYou are welcome to\n[report bugs](https://github.com/acornjs/acorn/issues) or create pull\nrequests on [github](https://github.com/acornjs/acorn).\n\n## Installation\n\nThe easiest way to install acorn is from [`npm`](https://www.npmjs.com/):\n\n```sh\nnpm install acorn-walk\n```\n\nAlternately, you can download the source and build acorn yourself:\n\n```sh\ngit clone https://github.com/acornjs/acorn.git\ncd acorn\nnpm install\n```\n\n## Interface\n\nAn algorithm for recursing through a syntax tree is stored as an\nobject, with a property for each tree node type holding a function\nthat will recurse through such a node. There are several ways to run\nsuch a walker.\n\n**simple**`(node, visitors, base, state)` does a 'simple' walk over a\ntree. `node` should be the AST node to walk, and `visitors` an object\nwith properties whose names correspond to node types in the [ESTree\nspec](https://github.com/estree/estree). The properties should contain\nfunctions that will be called with the node object and, if applicable\nthe state at that point. The last two arguments are optional. `base`\nis a walker algorithm, and `state` is a start state. The default\nwalker will simply visit all statements and expressions and not\nproduce a meaningful state. (An example of a use of state is to track\nscope at each point in the tree.)\n\n```js\nimport * as acorn from \"acorn\"\nimport * as walk from \"acorn-walk\"\n\nwalk.simple(acorn.parse(\"let x = 10\"), {\n  Literal(node) {\n    console.log(`Found a literal: ${node.value}`)\n  }\n})\n```\n\n**ancestor**`(node, visitors, base, state)` does a 'simple' walk over\na tree, building up an array of ancestor nodes (including the current node)\nand passing the array to the callbacks as a third parameter.\n\n```js\nimport * as acorn from \"acorn\"\nimport * as walk from \"acorn-walk\"\n\nwalk.ancestor(acorn.parse(\"foo('hi')\"), {\n  Literal(_node, _state, ancestors) {\n    console.log(\"This literal's ancestors are:\", ancestors.map(n => n.type))\n  }\n})\n```\n\n**recursive**`(node, state, functions, base)` does a 'recursive'\nwalk, where the walker functions are responsible for continuing the\nwalk on the child nodes of their target node. `state` is the start\nstate, and `functions` should contain an object that maps node types\nto walker functions. Such functions are called with `(node, state, c)`\narguments, and can cause the walk to continue on a sub-node by calling\nthe `c` argument on it with `(node, state)` arguments. The optional\n`base` argument provides the fallback walker functions for node types\nthat aren't handled in the `functions` object. If not given, the\ndefault walkers will be used.\n\n**make**`(functions, base)` builds a new walker object by using the\nwalker functions in `functions` and filling in the missing ones by\ntaking defaults from `base`.\n\n**full**`(node, callback, base, state)` does a 'full' walk over a\ntree, calling the callback with the arguments (node, state, type) for\neach node\n\n**fullAncestor**`(node, callback, base, state)` does a 'full' walk\nover a tree, building up an array of ancestor nodes (including the\ncurrent node) and passing the array to the callbacks as a third\nparameter.\n\n```js\nimport * as acorn from \"acorn\"\nimport * as walk from \"acorn-walk\"\n\nwalk.full(acorn.parse(\"1 + 1\"), node => {\n  console.log(`There's a ${node.type} node at ${node.ch}`)\n})\n```\n\n**findNodeAt**`(node, start, end, test, base, state)` tries to locate\na node in a tree at the given start and/or end offsets, which\nsatisfies the predicate `test`. `start` and `end` can be either `null`\n(as wildcard) or a number. `test` may be a string (indicating a node\ntype) or a function that takes `(nodeType, node)` arguments and\nreturns a boolean indicating whether this node is interesting. `base`\nand `state` are optional, and can be used to specify a custom walker.\nNodes are tested from inner to outer, so if two nodes match the\nboundaries, the inner one will be preferred.\n\n**findNodeAround**`(node, pos, test, base, state)` is a lot like\n`findNodeAt`, but will match any node that exists 'around' (spanning)\nthe given position.\n\n**findNodeAfter**`(node, pos, test, base, state)` is similar to\n`findNodeAround`, but will match all nodes *after* the given position\n(testing outer nodes before inner nodes).\n"

This means that the application will fail to invoke functions which\n *   do not use explicit function annotation (and are thus unsuitable for minification), as described\n *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in\n *   tracking down the root of these bugs.\n *\n * @description\n *\n * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive\n * designates the **root element** of the application and is typically placed near the root element\n * of the page - e.g. on the `<body>` or `<html>` tags.\n *\n * There are a few things to keep in mind when using `ngApp`:\n * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`\n *   found in the document will be used to define the root element to auto-bootstrap as an\n *   application. To run multiple applications in an HTML document you must manually bootstrap them using\n *   {@link angular.bootstrap} instead.\n * - AngularJS applications cannot be nested within each other.\n * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.\n *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and\n *   {@link ngRoute.ngView `ngView`}.\n *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},\n *   causing animations to stop working and making the injector inaccessible from outside the app.\n *\n * You can specify an **AngularJS module** to be used as the root module for the application.  This\n * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It\n * should contain the application code needed or have dependencies on other modules that will\n * contain the code. See {@link angular.module} for more information.\n *\n * In the example below if the `ngApp` directive were not placed on the `html` element then the\n * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`\n * would not be resolved to `3`.\n *\n * `ngApp` is the easiest, and most common way to bootstrap an application.\n *\n <example module=\"ngAppDemo\" name=\"ng-app\">\n   <file name=\"index.html\">\n   <div ng-controller=\"ngAppDemoController\">\n     I can add: {{a}} + {{b}} =  {{ a+b }}\n   </div>\n   </file>\n   <file name=\"script.js\">\n   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {\n     $scope.a = 1;\n     $scope.b = 2;\n   });\n   </file>\n </example>\n *\n * Using `ngStrictDi`, you would see something like this:\n *\n <example ng-app-included=\"true\" name=\"strict-di\">\n   <file name=\"index.html\">\n   <div ng-app=\"ngAppStrictDemo\" ng-strict-di>\n       <div ng-controller=\"GoodController1\">\n           I can add: {{a}} + {{b}} =  {{ a+b }}\n\n           <p>This renders because the controller does not fail to\n              instantiate, by using explicit annotation style (see\n              script.js for details)\n           </p>\n       </div>\n\n       <div ng-controller=\"GoodController2\">\n           Name: <input ng-model=\"name\"><br />\n           Hello, {{name}}!\n\n           <p>This renders because the controller does not fail to\n              instantiate, by using explicit annotation style\n              (see script.js for details)\n           </p>\n       </div>\n\n       <div ng-controller=\"BadController\">\n           I can add: {{a}} + {{b}} =  {{ a+b }}\n\n           <p>The controller could not be instantiated, due to relying\n              on automatic function annotations (which are disabled in\n              strict mode).

@name angular.element\n * @module ng\n * @kind function\n *\n * @description\n * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.\n *\n * If jQuery is available, `angular.element` is an alias for the\n * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`\n * delegates to Angular's built-in subset of jQuery, called \"jQuery lite\" or **jqLite**.\n *\n * jqLite is a tiny, API-compatible subset of jQuery that allows\n * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most\n * commonly needed functionality with the goal of having a very small footprint.\n *\n * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the\n * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a\n * specific version of jQuery if multiple versions exist on the page.\n *\n * <div class=\"alert alert-info\">**Note:** All element references in Angular are always wrapped with jQuery or\n * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>\n *\n * <div class=\"alert alert-warning\">**Note:** Keep in mind that this function will not find elements\n * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`\n * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>\n *\n * ## Angular's jqLite\n * jqLite provides only the following jQuery methods:\n *\n * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument\n * - [`after()`](http://api.jquery.com/after/)\n * - [`append()`](http://api.jquery.com/append/)\n * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters\n * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData\n * - [`children()`](http://api.jquery.com/children/) - Does not support selectors\n * - [`clone()`](http://api.jquery.com/clone/)\n * - [`contents()`](http://api.jquery.com/contents/)\n * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.\n *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.\n * - [`data()`](http://api.jquery.com/data/)\n * - [`detach()`](http://api.jquery.com/detach/)\n * - [`empty()`](http://api.jquery.com/empty/)\n * - [`eq()`](http://api.jquery.com/eq/)\n * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name\n * - [`hasClass()`](http://api.jquery.com/hasClass/)\n * - [`html()`](http://api.jquery.com/html/)\n * - [`next()`](http://api.jquery.com/next/) - Does not support selectors\n * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData\n * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter\n * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors\n * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors\n * - [`prepend()`](http://api.jquery.com/prepend/)\n * - [`prop()`](http://api.jquery.com/prop/)\n * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)\n * - [`remove()`](http://api.jquery.com/remove/)\n * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes\n * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument\n * - [`removeData()`](http://api.jquery.com/removeData/)\n * - [`replaceWith()`](http://api.jquery.com/replaceWith/)\n * - [`text()`](http://api.jquery.com/text/)\n * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument\n * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers\n * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter\n * - [`val()`](http://api.jquery.com/val/)\n * - [`wrap()`](http://api.jquery.com/wrap/)\n *\n * ## jQuery/jqLite Extras\n * Angular also provides the following additional methods and events to both jQuery and jqLite:\n *\n * ### Events\n * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event\n *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM\n *    element before it is removed.\n *\n * ### Methods\n * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n *   retrieves controller associated with the `ngController` directive. If `name` is provided as\n *   camelCase directive name, then the controller for this directive will be retrieved (e.g.\n *   `'ngModel'`).\n * - `injector()` - retrieves the injector of the current element or its parent.\n * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current\n *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to\n *   be enabled.\n * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the\n *   current element. This getter should be used only on elements that contain a directive which starts a new isolate\n *   scope. Calling `scope()` on this element always returns the original non-isolate scope.\n *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.\n * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top\n *   parent element is reached.\n *\n * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See\n * https://github.com/angular/angular.js/issues/14251 for more information.\n *\n * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.\n * @returns {Object} jQuery object.\n */\n\nJQLite.expando = 'ng339';\n\nvar jqCache = JQLite.cache = {},\n    jqId = 1;\n\n/*\n * !!!

You can see the default values below.\n * </div>\n *\n * Therefore the above can be simplified as:\n *\n * ```js\n *   var myModule = angular.module(...);\n *\n *   myModule.directive('directiveName', function factory(injectables) {\n *     var directiveDefinitionObject = {\n *       link: function postLink(scope, iElement, iAttrs) { ... }\n *     };\n *     return directiveDefinitionObject;\n *     // or\n *     // return function postLink(scope, iElement, iAttrs) { ... }\n *   });\n * ```\n *\n * ### Life-cycle hooks\n * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the\n * directive:\n * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and\n *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on\n *   this element). This is a good place to put initialization code for your controller.\n * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The\n *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an\n *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a\n *   component such as cloning the bound value to prevent accidental mutation of the outer value.\n * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on\n *   changes. Any actions that you wish to take in response to the changes that you detect must be\n *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook\n *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not\n *   be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;\n *   if detecting changes, you must store the previous value(s) for comparison to the current values.\n * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing\n *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in\n *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent\n *   components will have their `$onDestroy()` hook called before child components.\n * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link\n *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.\n *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since\n *   they are waiting for their template to load asynchronously and their own compilation and linking has been\n *   suspended until that occurs.\n *\n * #### Comparison with Angular 2 life-cycle hooks\n * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are\n * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:\n *\n * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.\n * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.\n *   In Angular 2 you can only define hooks on the prototype of the Component class.\n * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to\n *   `ngDoCheck` in Angular 2\n * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be\n *   propagated throughout the application.\n *   Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an\n *   error or do nothing depending upon the state of `enableProdMode()`.\n *\n * #### Life-cycle hook examples\n *\n * This example shows how you can check for mutations to a Date object even though the identity of the object\n * has not changed.\n *\n * <example name=\"doCheckDateExample\" module=\"do-check-module\">\n *   <file name=\"app.js\">\n *     angular.module('do-check-module', [])\n *       .component('app', {\n *         template:\n *           'Month: <input ng-model=\"$ctrl.month\" ng-change=\"$ctrl.updateDate()\">' +\n *           'Date: {{ $ctrl.date }}' +\n *           '<test date=\"$ctrl.date\"></test>',\n *         controller: function() {\n *           this.date = new Date();\n *           this.month = this.date.getMonth();\n *           this.updateDate = function() {\n *             this.date.setMonth(this.month);\n *           };\n *         }\n *       })\n *       .component('test', {\n *         bindings: { date: '<' },\n *         template:\n *           '<pre>{{ $ctrl.log | json }}</pre>',\n *         controller: function() {\n *           var previousValue;\n *           this.log = [];\n *           this.$doCheck = function() {\n *             var currentValue = this.date && this.date.valueOf();\n *             if (previousValue !== currentValue) {\n *               this.log.push('doCheck: date mutated: ' + this.date);\n *               previousValue = currentValue;\n *             }\n *           };\n *         }\n *       });\n *   </file>\n *   <file name=\"index.html\">\n *     <app></app>\n *   </file>\n * </example>\n *\n * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the\n * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large\n * arrays or objects can have a negative impact on your application performance)\n *\n * <example name=\"doCheckArrayExample\" module=\"do-check-module\">\n *   <file name=\"index.html\">\n *     <div ng-init=\"items = []\">\n *       <button ng-click=\"items.push(items.length)\">Add Item</button>\n *       <button ng-click=\"items = []\">Reset Items</button>\n *       <pre>{{ items }}</pre>\n *       <test items=\"items\"></test>\n *     </div>\n *   </file>\n *   <file name=\"app.js\">\n *      angular.module('do-check-module', [])\n *        .component('test', {\n *          bindings: { items: '<' },\n *          template:\n *            '<pre>{{ $ctrl.log | json }}</pre>',\n *          controller: function() {\n *            this.log = [];\n *\n *            this.$doCheck = function() {\n *              if (this.items_ref !== this.items) {\n *                this.log.push('doCheck: items changed');\n *                this.items_ref = this.items;\n *              }\n *              if (!angular.equals(this.items_clone, this.items)) {\n *                this.log.push('doCheck: items mutated');\n *                this.items_clone = angular.copy(this.items);\n *              }\n *            };\n *          }\n *        });\n *   </file>\n * </example>\n *\n *\n * ### Directive Definition Object\n *\n * The directive definition object provides instructions to the {@link ng.$compile\n * compiler}. The attributes are:\n *\n * #### `multiElement`\n * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between\n * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them\n * together as the directive elements. It is recommended that this feature be used on directives\n * which are not strictly behavioral (such as {@link ngClick}), and which\n * do not manipulate or replace child nodes (such as {@link ngInclude}).\n *\n * #### `priority`\n * When there are multiple directives defined on a single DOM element, sometimes it\n * is necessary to specify the order in which the directives are applied. The `priority` is used\n * to sort the directives before their `compile` functions get called. Priority is defined as a\n * number. Directives with greater numerical `priority` are compiled first. Pre-link functions\n * are also run in priority order, but post-link functions are run in reverse order. The order\n * of directives with the same priority is undefined. The default priority is `0`.\n *\n * #### `terminal`\n * If set to true then the current `priority` will be the last set of directives\n * which will execute (any directives at the current priority will still execute\n * as the order of execution on same `priority` is undefined). Note that expressions\n * and other directives used in the directive's template will also be excluded from execution.\n *\n * #### `scope`\n * The scope property can be `false`, `true`, or an object:\n *\n * * **`false` (default):** No scope will be created for the directive. The directive will use its\n * parent's scope.\n *\n * * **`true`:** A new child scope that prototypically inherits from its parent will be created for\n * the directive's element. If multiple directives on the same element request a new scope,\n * only one new scope is created.\n *\n * * **`{...}` (an object hash):** A new \"isolate\" scope is created for the directive's element. The\n * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent\n * scope. This is useful when creating reusable components, which should not accidentally read or modify\n * data in the parent scope.\n *\n * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the\n * directive's element. These local properties are useful for aliasing values for templates. The keys in\n * the object hash map to the name of the property on the isolate scope; the values define how the property\n * is bound to the parent scope, via matching attributes on the directive's element:\n *\n * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is\n *   always a string since DOM attributes are strings. If no `attr` name is specified then the\n *   attribute name is assumed to be the same as the local name. Given `<my-component\n *   my-attr=\"hello {{name}}\">` and the isolate scope definition `scope: { localName:'@myAttr' }`,\n *   the directive's scope property `localName` will reflect the interpolated value of `hello\n *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's\n *   scope. The `name` is read from the parent scope (not the directive's scope).\n *\n * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression\n *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.\n *   If no `attr` name is specified then the attribute name is assumed to be the same as the local\n *   name. Given `<my-component my-attr=\"parentModel\">` and the isolate scope definition `scope: {\n *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the\n *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in\n *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:\n *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't\n *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})\n *   will be thrown upon discovering changes to the local value, since it will be impossible to sync\n *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}\n *   method is used for tracking changes, and the equality check is based on object identity.\n *   However, if an object literal or an array literal is passed as the binding expression, the\n *   equality check is done by value (using the {@link angular.equals} function). It's also possible\n *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection\n *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).\n *\n  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an\n *   expression passed via the attribute `attr`. The expression is evaluated in the context of the\n *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the\n *   local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.\n *\n *   For example, given `<my-component my-attr=\"parentModel\">` and directive definition of\n *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the\n *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected\n *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however\n *   two caveats:\n *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply\n *     sets the same value. That means if your bound value is an object, changes to its properties\n *     in the isolated scope will be reflected in the parent scope (because both reference the same object).\n *     2. one-way binding watches changes to the **identity** of the parent value. That means the\n *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference\n *     to the value has changed. In most cases, this should not be of concern, but can be important\n *     to know if you one-way bind to an object, and then replace that object in the isolated scope.\n *     If you now change a property of the object in your parent scope, the change will not be\n *     propagated to the isolated scope, because the identity of the object on the parent scope\n *     has not changed. Instead you must assign a new object.\n *\n *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings\n *   back to the parent. However, it does not make this completely impossible.\n *\n * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If\n *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.\n *   Given `<my-component my-attr=\"count = count + value\">` and the isolate scope definition `scope: {\n *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for\n *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope\n *   via an expression to the parent scope. This can be done by passing a map of local variable names\n *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`\n *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.\n *\n * In general it's possible to apply more than one directive to one element, but there might be limitations\n * depending on the type of scope required by the directives. The following points will help explain these limitations.\n * For simplicity only two directives are taken into account, but it is also applicable for several directives:\n *\n * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope\n * * **child scope** + **no scope** =>  Both directives will share one single child scope\n * * **child scope** + **child scope** =>  Both directives will share one single child scope\n * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use\n * its parent's scope\n * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot\n * be applied to the same element.\n * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives\n * cannot be applied to the same element.\n *\n *\n * #### `bindToController`\n * This property is used to bind scope properties directly to the controller. It can be either\n * `true` or an object hash with the same format as the `scope` property.\n *\n * When an isolate scope is used for a directive (see above), `bindToController: true` will\n * allow a component to have its properties bound to the controller, rather than to scope.\n *\n * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller\n * properties. You can access these bindings once they have been initialized by providing a controller method called\n * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings\n * initialized.\n *\n * <div class=\"alert alert-warning\">\n * **Deprecation warning:** although bindings for non-ES6 class controllers are currently\n * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization\n * code that relies upon bindings inside a `$onInit` method on the controller, instead.\n * </div>\n *\n * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.\n * This will set up the scope bindings to the controller directly. Note that `scope` can still be used\n * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate\n * scope (useful for component directives).\n *\n * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.\n *\n *\n * #### `controller`\n * Controller constructor function. The controller is instantiated before the\n * pre-linking phase and can be accessed by other directives (see\n * `require` attribute). This allows the directives to communicate with each other and augment\n * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n *\n * * `$scope` - Current scope associated with the element\n * * `$element` - Current element\n * * `$attrs` - Current attributes object for the element\n * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:\n *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:\n *    * `scope`: (optional) override the scope.\n *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.\n *    * `futureParentElement` (optional):\n *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.\n *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.\n *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)\n *          and when the `cloneLinkingFn` is passed,\n *          as those elements need to created and cloned in a special way when they are defined outside their\n *          usual containers (e.g. like `<svg>`).\n *        * See also the `directive.templateNamespace` property.\n *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)\n *      then the default transclusion is provided.\n *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns\n *    `true` if the specified slot contains content (i.e. one or more DOM nodes).\n *\n * #### `require`\n * Require another directive and inject its controller as the fourth argument to the linking function. The\n * `require` property can be a string, an array or an object:\n * * a **string** containing the name of the directive to pass to the linking function\n * * an **array** containing the names of directives to pass to the linking function. The argument passed to the\n * linking function will be an array of controllers in the same order as the names in the `require` property\n * * an **object** whose property values are the names of the directives to pass to the linking function. The argument\n * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding\n * controllers.\n *\n * If the `require` property is an object and `bindToController` is truthy, then the required controllers are\n * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers\n * have been constructed but before `$onInit` is called.\n * If the name of the required controller is the same as the local name (the key), the name can be\n * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.\n * See the {@link $compileProvider#component} helper for an example of how this can be used.\n * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is\n * raised (unless no link function is specified and the required controllers are not being bound to the directive\n * controller, in which case error checking is skipped). The name can be prefixed with:\n *\n * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.\n * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.\n * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.\n * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.\n * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass\n *   `null` to the `link` fn if not found.\n * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass\n *   `null` to the `link` fn if not found.\n *\n *\n * #### `controllerAs`\n * Identifier name for a reference to the controller in the directive's scope.\n * This allows the controller to be referenced from the directive template. This is especially\n * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible\n * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the\n * `controllerAs` reference might overwrite a property that already exists on the parent scope.\n *\n *\n * #### `restrict`\n * String of subset of `EACM` which restricts the directive to a specific directive\n * declaration style. If omitted, the defaults (elements and attributes) are used.\n *\n * * `E` - Element name (default): `<my-directive></my-directive>`\n * * `A` - Attribute (default): `<div my-directive=\"exp\"></div>`\n * * `C` - Class: `<div class=\"my-directive: exp;\"></div>`\n * * `M` - Comment: `<!-- directive: my-directive exp -->`\n *\n *\n * #### `templateNamespace`\n * String representing the document type used by the markup in the template.\n * AngularJS needs this information as those elements need to be created and cloned\n * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.\n *\n * * `html` - All root nodes in the template are HTML. Root nodes may also be\n *   top-level elements such as `<svg>` or `<math>`.\n * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).\n * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).\n *\n * If no `templateNamespace` is specified, then the namespace is considered to be `html`.\n *\n * #### `template`\n * HTML markup that may:\n * * Replace the contents of the directive's element (default).\n * * Replace the directive's element itself (if `replace` is true - DEPRECATED).\n * * Wrap the contents of the directive's element (if `transclude` is true).\n *\n * Value may be:\n *\n * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.\n * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`\n *   function api below) and returns a string value.\n *\n *\n * #### `templateUrl`\n * This is similar to `template` but the template is loaded from the specified URL, asynchronously.\n *\n * Because template loading is asynchronous the compiler will suspend compilation of directives on that element\n * for later when the template has been resolved.  In the meantime it will continue to compile and link\n * sibling and parent elements as though this element had not contained any directives.\n *\n * The compiler does not suspend the entire compilation to wait for templates to be loaded because this\n * would result in the whole app \"stalling\" until all templates are loaded asynchronously - even in the\n * case when only one deeply nested directive has `templateUrl`.\n *\n * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}\n *\n * You can specify `templateUrl` as a string representing the URL or as a function which takes two\n * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns\n * a string value representing the url.  In either case, the template URL is passed through {@link\n * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.\n *\n *\n * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)\n * specify what the template should replace. Defaults to `false`.\n *\n * * `true` - the template will replace the directive's element.\n * * `false` - the template will replace the contents of the directive's element.\n *\n * The replacement process migrates all of the attributes / classes from the old element to the new\n * one. See the {@link guide/directive#template-expanding-directive\n * Directives Guide} for an example.\n *\n * There are very few scenarios where element replacement is required for the application function,\n * the main one being reusable custom components that are used within SVG contexts\n * (because SVG doesn't work with custom elements in the DOM tree).\n *\n * #### `transclude`\n * Extract the contents of the element where the directive appears and make it available to the directive.\n * The contents are compiled and provided to the directive as a **transclusion function**. See the\n * {@link $compile#transclusion Transclusion} section below.\n *\n *\n * #### `compile`\n *\n * ```js\n *   function compile(tElement, tAttrs, transclude) { ... }\n * ```\n *\n * The compile function deals with transforming the template DOM. Since most directives do not do\n * template transformation, it is not used often. The compile function takes the following arguments:\n *\n *   * `tElement` - template element - The element where the directive has been declared. It is\n *     safe to do template transformation on the element and child elements only.\n *\n *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared\n *     between all directive compile functions.\n *\n *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`\n *\n * <div class=\"alert alert-warning\">\n * **Note:** The template instance and the link instance may be different objects if the template has\n * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that\n * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration\n * should be done in a linking function rather than in a compile function.\n * </div>\n\n * <div class=\"alert alert-warning\">\n * **Note:** The compile function cannot handle directives that recursively use themselves in their\n * own templates or compile functions. Compiling these directives results in an infinite loop and\n * stack overflow errors.\n *\n * This can be avoided by manually using $compile in the postLink function to imperatively compile\n * a directive's template instead of relying on automatic template compilation via `template` or\n * `templateUrl` declaration or manual compilation inside the compile function.\n * </div>\n *\n * <div class=\"alert alert-danger\">\n * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it\n *   e.g. does not know about the right outer scope. Please use the transclude function that is passed\n *   to the link function instead.\n * </div>\n\n * A compile function can have a return value which can be either a function or an object.\n *\n * * returning a (post-link) function - is equivalent to registering the linking function via the\n *   `link` property of the config object when the compile function is empty.\n *\n * * returning an object with function(s) registered via `pre` and `post` properties - allows you to\n *   control when a linking function should be called during the linking phase. See info about\n *   pre-linking and post-linking functions below.\n *\n *\n * #### `link`\n * This property is used only if the `compile` property is not defined.\n *\n * ```js\n *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }\n * ```\n *\n * The link function is responsible for registering DOM listeners as well as updating the DOM. It is\n * executed after the template has been cloned. This is where most of the directive logic will be\n * put.\n *\n *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the\n *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.\n *\n *   * `iElement` - instance element - The element where the directive is to be used. It is safe to\n *     manipulate the children of the element only in `postLink` function since the children have\n *     already been linked.\n *\n *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared\n *     between all directive linking functions.\n *\n *   * `controller` - the directive's required controller instance(s) - Instances are shared\n *     among all directives, which allows the directives to use the controllers as a communication\n *     channel. The exact value depends on the directive's `require` property:\n *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one\n *       * `string`: the controller instance\n *       * `array`: array of controller instances\n *\n *     If a required controller cannot be found, and it is optional, the instance is `null`,\n *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.\n *\n *     Note that you can also require the directive's own controller - it will be made available like\n *     any other controller.\n *\n *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.\n *     This is the same as the `$transclude` parameter of directive controllers,\n *     see {@link ng.$compile#-controller- the controller section for details}.\n *     `function([scope], cloneLinkingFn, futureParentElement)`.\n *\n * #### Pre-linking function\n *\n * Executed before the child elements are linked. Not safe to do DOM transformation since the\n * compiler linking function will fail to locate the correct elements for linking.\n *\n * #### Post-linking function\n *\n * Executed after the child elements are linked.\n *\n * Note that child elements that contain `templateUrl` directives will not have been compiled\n * and linked since they are waiting for their template to load asynchronously and their own\n * compilation and linking has been suspended until that occurs.\n *\n * It is safe to do DOM transformation in the post-linking function on elements that are not waiting\n * for their async templates to be resolved.\n *\n *\n * ### Transclusion\n *\n * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and\n * copying them to another part of the DOM, while maintaining their connection to the original AngularJS\n * scope from where they were taken.\n *\n * Transclusion is used (often with {@link ngTransclude}) to insert the\n * original contents of a directive's element into a specified place in the template of the directive.\n * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded\n * content has access to the properties on the scope from which it was taken, even if the directive\n * has isolated scope.\n * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.\n *\n * This makes it possible for the widget to have private state for its template, while the transcluded\n * content has access to its originating scope.\n *\n * <div class=\"alert alert-warning\">\n * **Note:** When testing an element transclude directive you must not place the directive at the root of the\n * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives\n * Testing Transclusion Directives}.\n * </div>\n *\n * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the\n * directive's element, the entire element or multiple parts of the element contents:\n *\n * * `true` - transclude the content (i.e. the child nodes) of the directive's element.\n * * `'element'` - transclude the whole of the directive's element including any directives on this\n *   element that defined at a lower priority than this directive. When used, the `template`\n *   property is ignored.\n * * **`{...}` (an object hash):** - map elements of the content onto transclusion \"slots\" in the template.\n *\n * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.\n *\n * This object is a map where the keys are the name of the slot to fill and the value is an element selector\n * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)\n * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).\n *\n * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}\n *\n * If the element selector is prefixed with a `?` then that slot is optional.\n *\n * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to\n * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.\n *\n * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements\n * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call\n * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and\n * injectable into the directive's controller.\n *\n *\n * #### Transclusion Functions\n *\n * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion\n * function** to the directive's `link` function and `controller`. This transclusion function is a special\n * **linking function** that will return the compiled contents linked to a new transclusion scope.\n *\n * <div class=\"alert alert-info\">\n * If you are just using {@link ngTransclude} then you don't need to worry about this function, since\n * ngTransclude will deal with it for us.\n * </div>\n *\n * If you want to manually control the insertion and removal of the transcluded content in your directive\n * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery\n * object that contains the compiled DOM, which is linked to the correct transclusion scope.\n *\n * When you call a transclusion function you can pass in a **clone attach function**. This function accepts\n * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded\n * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.\n *\n * <div class=\"alert alert-info\">\n * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function\n * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.\n * </div>\n *\n * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone\n * attach function**:\n *\n * ```js\n * var transcludedContent, transclusionScope;\n *\n * $transclude(function(clone, scope) {\n *   element.append(clone);\n *   transcludedContent = clone;\n *   transclusionScope = scope;\n * });\n * ```\n *\n * Later, if you want to remove the transcluded content from your DOM then you should also destroy the\n * associated transclusion scope:\n *\n * ```js\n * transcludedContent.remove();\n * transclusionScope.$destroy();\n * ```\n *\n * <div class=\"alert alert-info\">\n * **Best Practice**: if you intend to add and remove transcluded content manually in your directive\n * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),\n * then you are also responsible for calling `$destroy` on the transclusion scope.\n * </div>\n *\n * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}\n * automatically destroy their transcluded clones as necessary so you do not need to worry about this if\n * you are simply using {@link ngTransclude} to inject the transclusion into your directive.\n *\n *\n * #### Transclusion Scopes\n *\n * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion\n * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed\n * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it\n * was taken.\n *\n * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look\n * like this:\n *\n * ```html\n * <div ng-app>\n *   <div isolate>\n *     <div transclusion>\n *     </div>\n *   </div>\n * </div>\n * ```\n *\n * The `$parent` scope hierarchy will look like this:\n *\n   ```\n   - $rootScope\n     - isolate\n       - transclusion\n   ```\n *\n * but the scopes will inherit prototypically from different scopes to their `$parent`.\n *\n   ```\n   - $rootScope\n     - transclusion\n   - isolate\n   ```\n *\n *\n * ### Attributes\n *\n * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the\n * `link()` or `compile()` functions. It has a variety of uses.\n *\n * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:\n *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access\n *   to the attributes.\n *\n * * *Directive inter-communication:* All directives share the same instance of the attributes\n *   object which allows the directives to use the attributes object as inter directive\n *   communication.\n *\n * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object\n *   allowing other directives to read the interpolated value.\n *\n * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes\n *   that contain interpolation (e.g. `src=\"{{bar}}\"`). Not only is this very efficient but it's also\n *   the only way to easily get the actual value because during the linking phase the interpolation\n *   hasn't been evaluated yet and so the value is at this time set to `undefined`.\n *\n * ```js\n * function linkingFn(scope, elm, attrs, ctrl) {\n *   // get the attribute value\n *   console.log(attrs.ngModel);\n *\n *   // change the attribute\n *   attrs.$set('ngModel', 'new value');\n *\n *   // observe changes to interpolated attribute\n *   attrs.$observe('ngModel', function(value) {\n *     console.log('ngModel has changed value to ' + value);\n *   });\n * }\n * ```\n *\n * ## Example\n *\n * <div class=\"alert alert-warning\">\n * **Note**: Typically directives are registered with `module.directive`. The example below is\n * to illustrate how `$compile` works.\n * </div>\n *\n <example module=\"compileExample\" name=\"compile\">\n   <file name=\"index.html\">\n    <script>\n      angular.module('compileExample', [], function($compileProvider) {\n        // configure new 'compile' directive by passing a directive\n        // factory function.

Where:\n *\n *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.\n *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the\n *  `template` and call the `cloneAttachFn` function allowing the caller to attach the\n *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is\n *  called as: <br/> `cloneAttachFn(clonedElement, scope)` where:\n *\n *      * `clonedElement` - is a clone of the original `element` passed into the compiler.\n *      * `scope` - is the current scope with which the linking function is working with.\n *\n *  * `options` - An optional object hash with linking options. If `options` is provided, then the following\n *  keys may be used to control linking behavior:\n *\n *      * `parentBoundTranscludeFn` - the transclude function made available to\n *        directives; if given, it will be passed through to the link functions of\n *        directives found in `element` during compilation.\n *      * `transcludeControllers` - an object hash with keys that map controller names\n *        to a hash with the key `instance`, which maps to the controller instance;\n *        if given, it will make the controllers available to directives on the compileNode:\n *        ```\n *        {\n *          parent: {\n *            instance: parentControllerInstance\n *          }\n *        }\n *        ```\n *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add\n *        the cloned elements; only needed for transcludes that are allowed to contain non html\n *        elements (e.g. SVG elements). See also the directive.controller property.\n *\n * Calling the linking function returns the element of the template. It is either the original\n * element passed in, or the clone of the element if the `cloneAttachFn` is provided.\n *\n * After linking the view is not updated until after a call to $digest which typically is done by\n * Angular automatically.\n *\n * If you need access to the bound view, there are two ways to do it:\n *\n * - If you are not asking the linking function to clone the template, create the DOM element(s)\n *   before you send them to the compiler and keep this reference around.\n *   ```js\n *     var element = $compile('<p>{{total}}</p>')(scope);\n *   ```\n *\n * - if on the other hand, you need the element to be cloned, the view reference from the original\n *   example would not point to the clone, but rather to the original template that was cloned.

Any response status code outside of that range is\n     * considered an error status and will result in the error callback being called.\n     * Also, status codes less than -1 are normalized to zero. -1 usually means the request was\n     * aborted, e.g. using a `config.timeout`.\n     * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning\n     * that the outcome (success or error) will be determined by the final response status code.\n     *\n     *\n     * ## Shortcut methods\n     *\n     * Shortcut methods are also available. All shortcut methods require passing in the URL, and\n     * request data must be passed in for POST/PUT requests. An optional config can be passed as the\n     * last argument.\n     *\n     * ```js\n     *   $http.get('/someUrl', config).then(successCallback, errorCallback);\n     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);\n     * ```\n     *\n     * Complete list of shortcut methods:\n     *\n     * - {@link ng.$http#get $http.get}\n     * - {@link ng.$http#head $http.head}\n     * - {@link ng.$http#post $http.post}\n     * - {@link ng.$http#put $http.put}\n     * - {@link ng.$http#delete $http.delete}\n     * - {@link ng.$http#jsonp $http.jsonp}\n     * - {@link ng.$http#patch $http.patch}\n     *\n     *\n     * ## Writing Unit Tests that use $http\n     * When unit testing (using {@link ngMock ngMock}), it is necessary to call\n     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending\n     * request using trained responses.\n     *\n     * ```\n     * $httpBackend.expectGET(...);\n     * $http.get(...);\n     * $httpBackend.flush();\n     * ```\n     *\n     * ## Setting HTTP Headers\n     *\n     * The $http service will automatically add certain HTTP headers to all requests. These defaults\n     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n     * object, which currently contains this default configuration:\n     *\n     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n     *   - <code>Accept: application/json, text/plain, \\*&#65279;/&#65279;\\*</code>\n     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n     *   - `Content-Type: application/json`\n     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n     *   - `Content-Type: application/json`\n     *\n     * To add or overwrite these defaults, simply add or remove a property from these configuration\n     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n     * with the lowercased HTTP method name as the key, e.g.\n     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.\n     *\n     * The defaults can also be set at runtime via the `$http.defaults` object in the same\n     * fashion. For example:\n     *\n     * ```\n     * module.run(function($http) {\n     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';\n     * });\n     * ```\n     *\n     * In addition, you can supply a `headers` property in the config object passed when\n     * calling `$http(config)`, which overrides the defaults without changing them globally.\n     *\n     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,\n     * Use the `headers` property, setting the desired header to `undefined`. For example:\n     *\n     * ```js\n     * var req = {\n     *  method: 'POST',\n     *  url: 'http://example.com',\n     *  headers: {\n     *    'Content-Type': undefined\n     *  },\n     *  data: { test: 'test' }\n     * }\n     *\n     * $http(req).then(function(){...}, function(){...});\n     * ```\n     *\n     * ## Transforming Requests and Responses\n     *\n     * Both requests and responses can be transformed using transformation functions: `transformRequest`\n     * and `transformResponse`. These properties can be a single function that returns\n     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,\n     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.\n     *\n     * <div class=\"alert alert-warning\">\n     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.\n     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).\n     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest\n     * function will be reflected on the scope and in any templates where the object is data-bound.\n     * To prevent this, transform functions should have no side-effects.\n     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.\n     * </div>\n     *\n     * ### Default Transformations\n     *\n     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and\n     * `defaults.transformResponse` properties. If a request does not provide its own transformations\n     * then these will be applied.\n     *\n     * You can augment or replace the default transformations by modifying these properties by adding to or\n     * replacing the array.\n     *\n     * Angular provides the following default transformations:\n     *\n     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):\n     *\n     * - If the `data` property of the request configuration object contains an object, serialize it\n     *   into JSON format.\n     *\n     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):\n     *\n     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).\n     *  - If JSON response is detected, deserialize it using a JSON parser.\n     *\n     *\n     * ### Overriding the Default Transformations Per Request\n     *\n     * If you wish to override the request/response transformations only for a single request then provide\n     * `transformRequest` and/or `transformResponse` properties on the configuration object passed\n     * into `$http`.\n     *\n     * Note that if you provide these properties on the config object the default transformations will be\n     * overwritten. If you wish to augment the default transformations then you must include them in your\n     * local transformation array.\n     *\n     * The following code demonstrates adding a new response transformation to be run after the default response\n     * transformations have been run.\n     *\n     * ```js\n     * function appendTransform(defaults, transform) {\n     *\n     *   // We can't guarantee that the default transformation is an array\n     *   defaults = angular.isArray(defaults) ? defaults : [defaults];\n     *\n     *   // Append the new transformation to the defaults\n     *   return defaults.concat(transform);\n     * }\n     *\n     * $http({\n     *   url: '...',\n     *   method: 'GET',\n     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {\n     *     return doTransform(value);\n     *   })\n     * });\n     * ```\n     *\n     *\n     * ## Caching\n     *\n     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must\n     * set the config.cache value or the default cache value to TRUE or to a cache object (created\n     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes\n     * precedence over the default cache value.\n     *\n     * In order to:\n     *   * cache all responses - set the default cache value to TRUE or to a cache object\n     *   * cache a specific response - set config.cache value to TRUE or to a cache object\n     *\n     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,\n     * then the default `$cacheFactory(\"$http\")` object is used.\n     *\n     * The default cache value can be set by updating the\n     * {@link ng.$http#defaults `$http.defaults.cache`} property or the\n     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.\n     *\n     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using\n     * the relevant cache object. The next time the same request is made, the response is returned\n     * from the cache without sending a request to the server.\n     *\n     * Take note that:\n     *\n     *   * Only GET and JSONP requests are cached.\n     *   * The cache key is the request URL including search parameters; headers are not considered.\n     *   * Cached responses are returned asynchronously, in the same way as responses from the server.\n     *   * If multiple identical requests are made using the same cache, which is not yet populated,\n     *     one request will be made to the server and remaining requests will return the same response.\n     *   * A cache-control header on the response does not affect if or how responses are cached.\n     *\n     *\n     * ## Interceptors\n     *\n     * Before you start creating interceptors, be sure to understand the\n     * {@link ng.$q $q and deferred/promise APIs}.\n     *\n     * For purposes of global error handling, authentication, or any kind of synchronous or\n     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n     * able to intercept requests before they are handed to the server and\n     * responses before they are handed over to the application code that\n     * initiated these requests. The interceptors leverage the {@link ng.$q\n     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.\n     *\n     * The interceptors are service factories that are registered with the `$httpProvider` by\n     * adding them to the `$httpProvider.interceptors` array. The factory is called and\n     * injected with dependencies (if specified) and returns the interceptor.\n     *\n     * There are two kinds of interceptors (and two kinds of rejection interceptors):\n     *\n     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to\n     *     modify the `config` object or create a new one. The function needs to return the `config`\n     *     object directly, or a promise containing the `config` or a new `config` object.\n     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or\n     *     resolved with a rejection.\n     *   * `response`: interceptors get called with http `response` object. The function is free to\n     *     modify the `response` object or create a new one. The function needs to return the `response`\n     *     object directly, or as a promise containing the `response` or a new `response` object.\n     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or\n     *     resolved with a rejection.\n     *\n     *\n     * ```js\n     *   // register the interceptor as a service\n     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n     *     return {\n     *       // optional method\n     *       'request': function(config) {\n     *         // do something on success\n     *         return config;\n     *       },\n     *\n     *       // optional method\n     *      'requestError': function(rejection) {\n     *         // do something on error\n     *         if (canRecover(rejection)) {\n     *           return responseOrNewPromise\n     *         }\n     *         return $q.reject(rejection);\n     *       },\n     *\n     *\n     *\n     *       // optional method\n     *       'response': function(response) {\n     *         // do something on success\n     *         return response;\n     *       },\n     *\n     *       // optional method\n     *      'responseError': function(rejection) {\n     *         // do something on error\n     *         if (canRecover(rejection)) {\n     *           return responseOrNewPromise\n     *         }\n     *         return $q.reject(rejection);\n     *       }\n     *     };\n     *   });\n     *\n     *   $httpProvider.interceptors.push('myHttpInterceptor');\n     *\n     *\n     *   // alternatively, register the interceptor via an anonymous factory\n     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {\n     *     return {\n     *      'request': function(config) {\n     *          // same as above\n     *       },\n     *\n     *       'response': function(response) {\n     *          // same as above\n     *       }\n     *     };\n     *   });\n     * ```\n     *\n     * ## Security Considerations\n     *\n     * When designing web applications, consider security threats from:\n     *\n     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)\n     *\n     * Both server and the client must cooperate in order to eliminate these threats. Angular comes\n     * pre-configured with strategies that address these issues, but for this to work backend server\n     * cooperation is required.\n     *\n     * ### JSON Vulnerability Protection\n     *\n     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n     * allows third party website to turn your JSON resource URL into\n     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To\n     * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n     * Angular will automatically strip the prefix before processing it as JSON.\n     *\n     * For example if your server needs to return:\n     * ```js\n     * ['one','two']\n     * ```\n     *\n     * which is vulnerable to attack, your server can return:\n     * ```js\n     * )]}',\n     * ['one','two']\n     * ```\n     *\n     * Angular will strip the prefix, before processing the JSON.\n     *\n     *\n     * ### Cross Site Request Forgery (XSRF) Protection\n     *\n     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by\n     * which the attacker can trick an authenticated user into unknowingly executing actions on your\n     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the\n     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP\n     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the\n     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.\n     * The header will not be set for cross-domain requests.\n     *\n     * To take advantage of this, your server needs to set a token in a JavaScript readable session\n     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure\n     * that only JavaScript running on your domain could have sent the request. The token must be\n     * unique for each user and must be verifiable by the server (to prevent the JavaScript from\n     * making up its own tokens). We recommend that the token is a digest of your site's\n     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)\n     * for added security.\n     *\n     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName\n     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,\n     * or the per-request config object.\n     *\n     * In order to prevent collisions in environments where multiple Angular apps share the\n     * same domain or subdomain, we recommend that each application uses unique cookie name.\n     *\n     * @param {object} config Object describing the request to be made and how it should be\n     *    processed. The object has following properties:\n     *\n     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)\n     *    - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;\n     *      or an object created by a call to `$sce.trustAsResourceUrl(url)`.\n     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized\n     *      with the `paramSerializer` and appended as GET parameters.\n     *    - **data** – `{string|Object}` – Data to be sent as the request message data.\n     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing\n     *      HTTP headers to send to the server. If the return value of a function is null, the\n     *      header will not be sent. Functions accept a config object as an argument.\n     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.\n     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.\n     *      The handler will be called in the context of a `$apply` block.\n     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload\n     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.\n     *      The handler will be called in the context of a `$apply` block.\n     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.\n     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.\n     *    - **transformRequest** –\n     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –\n     *      transform function or an array of such functions. The transform function takes the http\n     *      request body and headers and returns its transformed (typically serialized) version.\n     *      See {@link ng.$http#overriding-the-default-transformations-per-request\n     *      Overriding the Default Transformations}\n     *    - **transformResponse** –\n     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –\n     *      transform function or an array of such functions. The transform function takes the http\n     *      response body, headers and status and returns its transformed (typically deserialized) version.\n     *      See {@link ng.$http#overriding-the-default-transformations-per-request\n     *      Overriding the Default Transformations}\n     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to\n     *      prepare the string representation of request parameters (specified as an object).\n     *      If specified as string, it is interpreted as function registered with the\n     *      {@link $injector $injector}, which means you can create your own serializer\n     *      by registering it as a {@link auto.$provide#service service}.\n     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};\n     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}\n     *    - **cache** – `{boolean|Object}` – A boolean value or object created with\n     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.\n     *      See {@link $http#caching $http Caching} for more information.\n     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}\n     *      that should abort the request when resolved.\n     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the\n     *      XHR object.

Start and end markers\n     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).\n     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression\n     * or binding.\n     *\n     * This enables web-servers to prevent script injection attacks and defacing attacks, to some\n     * degree, while also enabling code examples to work without relying on the\n     * {@link ng.directive:ngNonBindable ngNonBindable} directive.\n     *\n     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,\n     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all\n     * interpolation start/end markers with their escaped counterparts.**\n     *\n     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered\n     * output when the $interpolate service processes the text. So, for HTML elements interpolated\n     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter\n     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,\n     * this is typically useful only when user-data is used in rendering a template from the server, or\n     * when otherwise untrusted data is used by a directive.\n     *\n     * <example name=\"interpolation\">\n     *  <file name=\"index.html\">\n     *    <div ng-init=\"username='A user'\">\n     *      <p ng-init=\"apptitle='Escaping demo'\">{{apptitle}}: \\{\\{ username = \"defaced value\"; \\}\\}\n     *        </p>\n     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the\n     *        application, but fails to accomplish their task, because the server has correctly\n     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)\n     *        characters.</p>\n     *      <p>Instead, the result of the attempted script injection is visible, and can be removed\n     *        from the database by an administrator.</p>\n     *    </div>\n     *  </file>\n     * </example>\n     *\n     * @knownIssue\n     * It is currently not possible for an interpolated expression to contain the interpolation end\n     * symbol.

exceptions)\n * when they are done processing.\n *\n * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred\n * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).\n *\n * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred\n * implementations, and the other which resembles ES6 (ES2015) promises to some degree.\n *\n * # $q constructor\n *\n * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`\n * function as the first argument. This is similar to the native Promise implementation from ES6,\n * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).\n *\n * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are\n * available yet.\n *\n * It can be used like so:\n *\n * ```js\n *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n *   // are available in the current lexical scope (they could have been injected or passed in).\n *\n *   function asyncGreet(name) {\n *     // perform some asynchronous operation, resolve or reject the promise when appropriate.\n *     return $q(function(resolve, reject) {\n *       setTimeout(function() {\n *         if (okToGreet(name)) {\n *           resolve('Hello, ' + name + '!');\n *         } else {\n *           reject('Greeting ' + name + ' is not allowed.');\n *         }\n *       }, 1000);\n *     });\n *   }\n *\n *   var promise = asyncGreet('Robin Hood');\n *   promise.then(function(greeting) {\n *     alert('Success: ' + greeting);\n *   }, function(reason) {\n *     alert('Failed: ' + reason);\n *   });\n * ```\n *\n * Note: progress/notify callbacks are not currently supported via the ES6-style interface.\n *\n * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.\n *\n * However, the more traditional CommonJS-style usage is still available, and documented below.\n *\n * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an\n * interface for interacting with an object that represents the result of an action that is\n * performed asynchronously, and may or may not be finished at any given point in time.\n *\n * From the perspective of dealing with error handling, deferred and promise APIs are to\n * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.\n *\n * ```js\n *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n *   // are available in the current lexical scope (they could have been injected or passed in).\n *\n *   function asyncGreet(name) {\n *     var deferred = $q.defer();\n *\n *     setTimeout(function() {\n *       deferred.notify('About to greet ' + name + '.');\n *\n *       if (okToGreet(name)) {\n *         deferred.resolve('Hello, ' + name + '!');\n *       } else {\n *         deferred.reject('Greeting ' + name + ' is not allowed.');\n *       }\n *     }, 1000);\n *\n *     return deferred.promise;\n *   }\n *\n *   var promise = asyncGreet('Robin Hood');\n *   promise.then(function(greeting) {\n *     alert('Success: ' + greeting);\n *   }, function(reason) {\n *     alert('Failed: ' + reason);\n *   }, function(update) {\n *     alert('Got notification: ' + update);\n *   });\n * ```\n *\n * At first it might not be obvious why this extra complexity is worth the trouble. The payoff\n * comes in the way of guarantees that promise and deferred APIs make, see\n * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.\n *\n * Additionally the promise api allows for composition that is very hard to do with the\n * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.\n * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the\n * section on serial or parallel joining of promises.\n *\n * # The Deferred API\n *\n * A new instance of deferred is constructed by calling `$q.defer()`.\n *\n * The purpose of the deferred object is to expose the associated Promise instance as well as APIs\n * that can be used for signaling the successful or unsuccessful completion, as well as the status\n * of the task.\n *\n * **Methods**\n *\n * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection\n *   constructed via `$q.reject`, the promise will be rejected instead.\n * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to\n *   resolving it with a rejection constructed via `$q.reject`.\n * - `notify(value)` - provides updates on the status of the promise's execution. This may be called\n *   multiple times before the promise is either resolved or rejected.\n *\n * **Properties**\n *\n * - promise – `{Promise}` – promise object associated with this deferred.\n *\n *\n * # The Promise API\n *\n * A new promise instance is created when a deferred instance is created and can be retrieved by\n * calling `deferred.promise`.\n *\n * The purpose of the promise object is to allow for interested parties to get access to the result\n * of the deferred task when it completes.\n *\n * **Methods**\n *\n * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or\n *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously\n *   as soon as the result is available. The callbacks are called with a single argument: the result\n *   or rejection reason. Additionally, the notify callback may be called zero or more times to\n *   provide a progress indication, before the promise is resolved or rejected.\n *\n *   This method *returns a new promise* which is resolved or rejected via the return value of the\n *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved\n *   with the value which is resolved in that promise using\n *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).\n *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be\n *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback\n *   arguments are optional.\n *\n * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`\n *\n * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,\n *   but to do so without modifying the final value. This is useful to release resources or do some\n *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full\n *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for\n *   more information.\n *\n * # Chaining promises\n *\n * Because calling the `then` method of a promise returns a new derived promise, it is easily\n * possible to create a chain of promises:\n *\n * ```js\n *   promiseB = promiseA.then(function(result) {\n *     return result + 1;\n *   });\n *\n *   // promiseB will be resolved immediately after promiseA is resolved and its value\n *   // will be the result of promiseA incremented by 1\n * ```\n *\n * It is possible to create chains of any length and since a promise can be resolved with another\n * promise (which will defer its resolution further), it is possible to pause/defer resolution of\n * the promises at any point in the chain. This makes it possible to implement powerful APIs like\n * $http's response interceptors.\n *\n *\n * # Differences between Kris Kowal's Q and $q\n *\n *  There are two main differences:\n *\n * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation\n *   mechanism in angular, which means faster propagation of resolution or rejection into your\n *   models and avoiding unnecessary browser repaints, which would result in flickering UI.\n * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains\n *   all the important functionality needed for common async tasks.\n *\n * # Testing\n *\n *  ```js\n *    it('should simulate promise', inject(function($q, $rootScope) {\n *      var deferred = $q.defer();\n *      var promise = deferred.promise;\n *      var resolvedValue;\n *\n *      promise.then(function(value) { resolvedValue = value; });\n *      expect(resolvedValue).toBeUndefined();\n *\n *      // Simulate resolving of promise\n *      deferred.resolve(123);\n *      // Note that the 'then' function does not get called synchronously.\n *      // This is because we want the promise API to always be async, whether or not\n *      // it got called synchronously or asynchronously.\n *      expect(resolvedValue).toBeUndefined();\n *\n *      // Propagate promise resolution to 'then' functions using $apply().\n *      $rootScope.$apply();\n *      expect(resolvedValue).toEqual(123);\n *    }));\n *  ```\n *\n * @param {function(function, function)} resolver Function which is responsible for resolving or\n *   rejecting the newly created promise.

One example of\n * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer\n * to these contexts as privileged or SCE contexts.\n *\n * As of version 1.2, Angular ships with SCE enabled by default.\n *\n * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow\n * one to execute arbitrary javascript by the use of the expression() syntax.  Refer\n * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.\n * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`\n * to the top of your HTML document.\n *\n * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for\n * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.\n *\n * Here's an example of a binding in a privileged context:\n *\n * ```\n * <input ng-model=\"userHtml\" aria-label=\"User input\">\n * <div ng-bind-html=\"userHtml\"></div>\n * ```\n *\n * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE\n * disabled, this application allows the user to render arbitrary HTML into the DIV.\n * In a more realistic example, one may be rendering user comments, blog articles, etc. via\n * bindings.  (HTML is just one example of a context where rendering user controlled input creates\n * security vulnerabilities.)\n *\n * For the case of HTML, you might use a library, either on the client side, or on the server side,\n * to sanitize unsafe HTML before binding to the value and rendering it in the document.\n *\n * How would you ensure that every place that used these types of bindings was bound to a value that\n * was sanitized by your library (or returned as safe for rendering by your server?)  How can you\n * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some\n * properties/fields and forgot to update the binding to the sanitized value?\n *\n * To be secure by default, you want to ensure that any such bindings are disallowed unless you can\n * determine that something explicitly says it's safe to use a value for binding in that\n * context.  You can then audit your code (a simple grep would do) to ensure that this is only done\n * for those values that you can easily tell are safe - because they were received from your server,\n * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps\n * allowing only the files in a specific directory to do this.  Ensuring that the internal API\n * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.\n *\n * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}\n * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to\n * obtain values that will be accepted by SCE / privileged contexts.\n *\n *\n * ## How does it work?\n *\n * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted\n * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link\n * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the\n * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.\n *\n * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link\n * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly\n * simplified):\n *\n * ```\n * var ngBindHtmlDirective = ['$sce', function($sce) {\n *   return function(scope, element, attr) {\n *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {\n *       element.html(value || '');\n *     });\n *   };\n * }];\n * ```\n *\n * ## Impact on loading templates\n *\n * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as\n * `templateUrl`'s specified by {@link guide/directive directives}.\n *\n * By default, Angular only loads templates from the same domain and protocol as the application\n * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl\n * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or\n * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist\n * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.\n *\n * *Please note*:\n * The browser's\n * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)\n * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)\n * policy apply in addition to this and may further restrict whether the template is successfully\n * loaded.  This means that without the right CORS policy, loading templates from a different domain\n * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some\n * browsers.\n *\n * ## This feels like too much overhead\n *\n * It's important to remember that SCE only applies to interpolation expressions.\n *\n * If your expressions are constant literals, they're automatically trusted and you don't need to\n * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.\n * `<div ng-bind-html=\"'<b>implicitly trusted</b>'\"></div>`) just works.\n *\n * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them\n * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.\n *\n * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load\n * templates in `ng-include` from your application's domain without having to even know about SCE.\n * It blocks loading templates from other domains or loading templates over http from an https\n * served document.  You can change these by setting your own custom {@link\n * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link\n * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.\n *\n * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an\n * application that's secure and can be audited to verify that with much more ease than bolting\n * security onto an application later.\n *\n * <a name=\"contexts\"></a>\n * ## What trusted context types are supported?\n *\n * | Context             | Notes          |\n * |---------------------|----------------|\n * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |\n * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |\n * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |\n * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.

All other characters\n *      match themselves.\n *    - `*`: matches zero or more occurrences of any character other than one of the following 6\n *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use\n *      in a whitelist.\n *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not\n *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.\n *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might\n *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.\n *      http://foo.example.com/templates/**).\n *  - **RegExp** (*see caveat below*)\n *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax\n *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to\n *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should\n *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a\n *      small number of cases.  A `.` character in the regex used when matching the scheme or a\n *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It\n *      is highly recommended to use the string patterns and only fall back to regular expressions\n *      as a last resort.\n *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is\n *      matched against the **entire** *normalized / absolute URL* of the resource being tested\n *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags\n *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.\n *    - If you are generating your JavaScript from some other templating engine (not\n *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),\n *      remember to escape your regular expression (and be aware that you might need more than\n *      one level of escaping depending on your templating engine and the way you interpolated\n *      the value.)  Do make use of your platform's escaping mechanism as it might be good\n *      enough before coding your own.  E.g. Ruby has\n *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)\n *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).\n *      Javascript lacks a similar built in function for escaping.  Take a look at Google\n *      Closure library's [goog.string.regExpEscape(s)](\n *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).\n *\n * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.\n *\n * ## Show me an example using SCE.\n *\n * <example module=\"mySceApp\" deps=\"angular-sanitize.js\" name=\"sce-service\">\n * <file name=\"index.html\">\n *   <div ng-controller=\"AppController as myCtrl\">\n *     <i ng-bind-html=\"myCtrl.explicitlyTrustedHtml\" id=\"explicitlyTrustedHtml\"></i><br><br>\n *     <b>User comments</b><br>\n *     By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when\n *     $sanitize is available.

However, this is strongly discouraged.  SCE gives you a lot of security benefits\n * for little coding overhead.  It will be much harder to take an SCE disabled application and\n * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE\n * for cases where you have a lot of existing code that was written before SCE was introduced and\n * you're migrating them a module at a time.\n *\n * That said, here's how you can completely disable SCE:\n *\n * ```\n * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {\n *   // Completely disable SCE.  For demonstration purposes only!\n *   // Do not use in new projects.\n *   $sceProvider.enabled(false);\n * });\n * ```\n *\n */\n\nfunction $SceProvider() {\n  var enabled = true;\n\n  /**\n   * @ngdoc method\n   * @name $sceProvider#enabled\n   * @kind function\n   *\n   * @param {boolean=} value If provided, then enables/disables SCE.\n   * @return {boolean} true if SCE is enabled, false otherwise.\n   *\n   * @description\n   * Enables/disables SCE and returns the current value.\n   */\n  this.enabled = function(value) {\n    if (arguments.length) {\n      enabled = !!value;\n    }\n    return enabled;\n  };\n\n\n  /* Design notes on the default implementation for SCE.\n   *\n   * The API contract for the SCE delegate\n   * -------------------------------------\n   * The SCE delegate object must provide the following 3 methods:\n   *\n   * - trustAs(contextEnum, value)\n   *     This method is used to tell the SCE service that the provided value is OK to use in the\n   *     contexts specified by contextEnum.  It must return an object that will be accepted by\n   *     getTrusted() for a compatible contextEnum and return this value.\n   *\n   * - valueOf(value)\n   *     For values that were not produced by trustAs(), return them as is.  For values that were\n   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if\n   *     trustAs is wrapping the given values into some type, this operation unwraps it when given\n   *     such a value.\n   *\n   * - getTrusted(contextEnum, value)\n   *     This function should return the a value that is safe to use in the context specified by\n   *     contextEnum or throw and exception otherwise.\n   *\n   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be\n   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For\n   * instance, an implementation could maintain a registry of all trusted objects by context.  In\n   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would\n   * return the same object passed in if it was found in the registry under a compatible context or\n   * throw an exception otherwise.  An implementation might only wrap values some of the time based\n   * on some criteria.  getTrusted() might return a value and not throw an exception for special\n   * constants or objects even if not wrapped.  All such implementations fulfill this contract.\n   *\n   *\n   * A note on the inheritance model for SCE contexts\n   * ------------------------------------------------\n   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This\n   * is purely an implementation details.\n   *\n   * The contract is simply this:\n   *\n   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)\n   *     will also succeed.\n   *\n   * Inheritance happens to capture this in a natural way.  In some future, we\n   * may not use inheritance anymore.  That is OK because no code outside of\n   * sce.js and sceSpecs.js would need to be aware of this detail.\n   */\n\n  this.$get = ['$parse', '$sceDelegate', function(\n                $parse,   $sceDelegate) {\n    // Support: IE 9-11 only\n    // Prereq: Ensure that we're not running in IE<11 quirks mode.

Normalizing means that a relative\n * URL will be resolved into an absolute URL in the context of the application document.\n * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related\n * properties are all populated to reflect the normalized URL.  This approach has wide\n * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See\n * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n *\n * Implementation Notes for IE\n * ---------------------------\n * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other\n * browsers.  However, the parsed components will not be set if the URL assigned did not specify\n * them.  (e.g. if you assign a.href = \"foo\", then a.protocol, a.host, etc. will be empty.)  We\n * work around that by performing the parsing in a 2nd step by taking a previously normalized\n * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the\n * properties such as protocol, hostname, port, etc.\n *\n * References:\n *   http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement\n *   http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n *   http://url.spec.whatwg.org/#urlutils\n *   https://github.com/angular/angular.js/pull/2902\n *   http://james.padolsey.com/javascript/parsing-urls-with-the-dom/\n *\n * @kind function\n * @param {string} url The URL to be parsed.\n * @description Normalizes and parses a URL.\n * @returns {object} Returns the normalized URL as a dictionary.\n *\n *   | member name   | Description    |\n *   |---------------|----------------|\n *   | href          | A normalized version of the provided URL if it was not an absolute URL |\n *   | protocol      | The protocol including the trailing colon                              |\n *   | host          | The host and port (if the port is non-default) of the normalizedUrl    |\n *   | search        | The search params, minus the question mark                             |\n *   | hash          | The hash string, minus the hash symbol\n *   | hostname      | The hostname\n *   | port          | The port, without \":\"\n *   | pathname      | The pathname, beginning with \"/\"\n *\n */\nfunction urlResolve(url) {\n  var href = url;\n\n  // Support: IE 9-11 only\n  if (msie) {\n    // Normalize before parse.

All strings or\n *     objects with string properties in `array` that match this string will be returned. This also\n *     applies to nested object properties.\n *     The predicate can be negated by prefixing the string with `!`.\n *\n *   - `Object`: A pattern object can be used to filter specific properties on objects contained\n *     by `array`. For example `{name:\"M\", phone:\"1\"}` predicate will return an array of items\n *     which have property `name` containing \"M\" and property `phone` containing \"1\". A special\n *     property name (`$` by default) can be used (e.g. as in `{$: \"text\"}`) to accept a match\n *     against any property of the object or its nested object properties. That's equivalent to the\n *     simple substring match with a `string` as described above. The special property name can be\n *     overwritten, using the `anyPropertyKey` parameter.\n *     The predicate can be negated by prefixing the string with `!`.\n *     For example `{name: \"!M\"}` predicate will return an array of items which have property `name`\n *     not containing \"M\".\n *\n *     Note that a named property will match properties on the same level only, while the special\n *     `$` property will match properties on the same level or deeper. E.g. an array item like\n *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but\n *     **will** be matched by `{$: 'John'}`.\n *\n *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.\n *     The function is called for each element of the array, with the element, its index, and\n *     the entire array itself as arguments.\n *\n *     The final result is an array of those elements that the predicate returned true for.\n *\n * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in\n *     determining if the expected value (from the filter expression) and actual value (from\n *     the object in the array) should be considered a match.\n *\n *   Can be one of:\n *\n *   - `function(actual, expected)`:\n *     The function will be given the object value and the predicate value to compare and\n *     should return true if both values should be considered equal.\n *\n *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.\n *     This is essentially strict comparison of expected and actual.\n *\n *   - `false`: A short hand for a function which will look for a substring match in a case\n *     insensitive way. Primitive values are converted to strings. Objects are not compared against\n *     primitives, unless they have a custom `toString` method (e.g. `Date` objects).\n *\n *\n *   Defaults to `false`.\n *\n * @param {string} [anyPropertyKey] The special property name that matches against any property.\n *     By default `$`.\n *\n * @example\n   <example name=\"filter-filter\">\n     <file name=\"index.html\">\n       <div ng-init=\"friends = [{name:'John', phone:'555-1276'},\n                                {name:'Mary', phone:'800-BIG-MARY'},\n                                {name:'Mike', phone:'555-4321'},\n                                {name:'Adam', phone:'555-5678'},\n                                {name:'Julie', phone:'555-8765'},\n                                {name:'Juliette', phone:'555-5678'}]\"></div>\n\n       <label>Search: <input ng-model=\"searchText\"></label>\n       <table id=\"searchTextResults\">\n         <tr><th>Name</th><th>Phone</th></tr>\n         <tr ng-repeat=\"friend in friends | filter:searchText\">\n           <td>{{friend.name}}</td>\n           <td>{{friend.phone}}</td>\n         </tr>\n       </table>\n       <hr>\n       <label>Any: <input ng-model=\"search.$\"></label> <br>\n       <label>Name only <input ng-model=\"search.name\"></label><br>\n       <label>Phone only <input ng-model=\"search.phone\"></label><br>\n       <label>Equality <input type=\"checkbox\" ng-model=\"strict\"></label><br>\n       <table id=\"searchObjResults\">\n         <tr><th>Name</th><th>Phone</th></tr>\n         <tr ng-repeat=\"friendObj in friends | filter:search:strict\">\n           <td>{{friendObj.name}}</td>\n           <td>{{friendObj.phone}}</td>\n         </tr>\n       </table>\n     </file>\n     <file name=\"protractor.js\" type=\"protractor\">\n       var expectFriendNames = function(expectedNames, key) {\n         element.all(by.repeater(key + ' in friends').column(key + '.name')).then(function(arr) {\n           arr.forEach(function(wd, i) {\n             expect(wd.getText()).toMatch(expectedNames[i]);\n           });\n         });\n       };\n\n       it('should search across all fields when filtering with a string', function() {\n         var searchText = element(by.model('searchText'));\n         searchText.clear();\n         searchText.sendKeys('m');\n         expectFriendNames(['Mary', 'Mike', 'Adam'], 'friend');\n\n         searchText.clear();\n         searchText.sendKeys('76');\n         expectFriendNames(['John', 'Julie'], 'friend');\n       });\n\n       it('should search in specific fields when filtering with a predicate object', function() {\n         var searchAny = element(by.model('search.$'));\n         searchAny.clear();\n         searchAny.sendKeys('i');\n         expectFriendNames(['Mary', 'Mike', 'Julie', 'Juliette'], 'friendObj');\n       });\n       it('should use a equal comparison when comparator is true', function() {\n         var searchName = element(by.model('search.name'));\n         var strict = element(by.model('strict'));\n         searchName.clear();\n         searchName.sendKeys('Julie');\n         strict.click();\n         expectFriendNames(['Julie'], 'friendObj');\n       });\n     </file>\n   </example>\n */\n\nfunction filterFilter() {\n  return function(array, expression, comparator, anyPropertyKey) {\n    if (!isArrayLike(array)) {\n      if (array == null) {\n        return array;\n      } else {\n        throw minErr('filter')('notarray', 'Expected array but received: {0}', array);\n      }\n    }\n\n    anyPropertyKey = anyPropertyKey || '$';\n    var expressionType = getTypeForFilter(expression);\n    var predicateFn;\n    var matchAgainstAnyProp;\n\n    switch (expressionType) {\n      case 'function':\n        predicateFn = expression;\n        break;\n      case 'boolean':\n      case 'null':\n      case 'number':\n      case 'string':\n        matchAgainstAnyProp = true;\n        // falls through\n      case 'object':\n        predicateFn = createPredicateFn(expression, comparator, anyPropertyKey, matchAgainstAnyProp);\n        break;\n      default:\n        return array;\n    }\n\n    return Array.prototype.filter.call(array, predicateFn);\n  };\n}\n\n// Helper functions for `filterFilter`\nfunction createPredicateFn(expression, comparator, anyPropertyKey, matchAgainstAnyProp) {\n  var shouldMatchPrimitives = isObject(expression) && (anyPropertyKey in expression);\n  var predicateFn;\n\n  if (comparator === true) {\n    comparator = equals;\n  } else if (!isFunction(comparator)) {\n    comparator = function(actual, expected) {\n      if (isUndefined(actual)) {\n        // No substring matching against `undefined`\n        return false;\n      }\n      if ((actual === null) || (expected === null)) {\n        // No substring matching against `null`;

The `expression` is evaluated against each item and the output is used\n * for comparing with other items.\n *\n * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in\n * ascending order.\n *\n * The comparison is done using the `comparator` function. If none is specified, a default, built-in\n * comparator is used (see below for details - in a nutshell, it compares numbers numerically and\n * strings alphabetically).\n *\n * ### Under the hood\n *\n * Ordering the specified `collection` happens in two phases:\n *\n * 1. All items are passed through the predicate (or predicates), and the returned values are saved\n *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed\n *    through a predicate that extracts the value of the `label` property, would be transformed to:\n *    ```\n *    {\n *      value: 'foo',\n *      type: 'string',\n *      index: ...\n *    }\n *    ```\n * 2. The comparator function is used to sort the items, based on the derived values, types and\n *    indices.\n *\n * If you use a custom comparator, it will be called with pairs of objects of the form\n * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal\n * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the\n * second, or `1` otherwise.\n *\n * In order to ensure that the sorting will be deterministic across platforms, if none of the\n * specified predicates can distinguish between two items, `orderBy` will automatically introduce a\n * dummy predicate that returns the item's index as `value`.\n * (If you are using a custom comparator, make sure it can handle this predicate as well.)\n *\n * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted\n * value for an item, `orderBy` will try to convert that object to a primitive value, before passing\n * it to the comparator. The following rules govern the conversion:\n *\n * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be\n *    used instead.<br />\n *    (If the object has a `valueOf()` method that returns another object, then the returned object\n *    will be used in subsequent steps.)\n * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that\n *    returns a primitive, its return value will be used instead.<br />\n *    (If the object has a `toString()` method that returns another object, then the returned object\n *    will be used in subsequent steps.)\n * 3. No conversion; the object itself is used.\n *\n * ### The default comparator\n *\n * The default, built-in comparator should be sufficient for most usecases. In short, it compares\n * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to\n * using their index in the original collection, and sorts values of different types by type.\n *\n * More specifically, it follows these steps to determine the relative order of items:\n *\n * 1. If the compared values are of different types, compare the types themselves alphabetically.\n * 2. If both values are of type `string`, compare them alphabetically in a case- and\n *    locale-insensitive way.\n * 3. If both values are objects, compare their indices instead.\n * 4. Otherwise, return:\n *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).\n *    - `-1`, if the 1st value is \"less than\" the 2nd value (compared using the `<` operator).\n *    -  `1`, otherwise.\n *\n * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being\n *           saved as numbers and not strings.\n * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e.\n *           `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to\n *           other values.\n *\n * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.\n * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of\n *    predicates) to be used by the comparator to determine the order of elements.\n *\n *    Can be one of:\n *\n *    - `Function`: A getter function. This function will be called with each item as argument and\n *      the return value will be used for sorting.\n *    - `string`: An Angular expression. This expression will be evaluated against each item and the\n *      result will be used for sorting. For example, use `'label'` to sort by a property called\n *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`\n *      property.<br />\n *      (The result of a constant expression is interpreted as a property name to be used for\n *      comparison. For example, use `'\"special name\"'` (note the extra pair of quotes) to sort by a\n *      property called `special name`.)<br />\n *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,\n *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,\n *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.\n *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the\n *      relative order of two items, the next predicate is used as a tie-breaker.\n *\n * **Note:** If the predicate is missing or empty then it defaults to `'+'`.\n *\n * @param {boolean=} reverse - If `true`, reverse the sorting order.\n * @param {(Function)=} comparator - The comparator function used to determine the relative order of\n *    value pairs.

This means that the outer form is valid when all of the child\n * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so\n * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to\n * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group\n * of controls needs to be determined.\n *\n * # CSS classes\n *  - `ng-valid` is set if the form is valid.\n *  - `ng-invalid` is set if the form is invalid.\n *  - `ng-pending` is set if the form is pending.\n *  - `ng-pristine` is set if the form is pristine.\n *  - `ng-dirty` is set if the form is dirty.\n *  - `ng-submitted` is set if the form was submitted.\n *\n * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n *\n *\n * # Submitting a form and preventing the default action\n *\n * Since the role of forms in client-side Angular applications is different than in classical\n * roundtrip apps, it is desirable for the browser not to translate the form submission into a full\n * page reload that sends the data to the server. Instead some javascript logic should be triggered\n * to handle the form submission in an application-specific way.\n *\n * For this reason, Angular prevents the default action (form submission to the server) unless the\n * `<form>` element has an `action` attribute specified.\n *\n * You can use one of the following two ways to specify what javascript method should be called when\n * a form is submitted:\n *\n * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element\n * - {@link ng.directive:ngClick ngClick} directive on the first\n  *  button or input field of type submit (input[type=submit])\n *\n * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}\n * or {@link ng.directive:ngClick ngClick} directives.\n * This is because of the following form submission rules in the HTML specification:\n *\n * - If a form has only one input field then hitting enter in this field triggers form submit\n * (`ngSubmit`)\n * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter\n * doesn't trigger submit\n * - if a form has one or more input fields and one or more buttons or input[type=submit] then\n * hitting enter in any of the input fields will trigger the click handler on the *first* button or\n * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)\n *\n * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is\n * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n * to have access to the updated model.\n *\n * ## Animation Hooks\n *\n * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.\n * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any\n * other validations that are performed within the form. Animations in ngForm are similar to how\n * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well\n * as JS animations.\n *\n * The following example shows a simple way to utilize CSS transitions to style a form element\n * that has been rendered as invalid after it has been validated:\n *\n * <pre>\n * //be sure to include ngAnimate as a module to hook into more\n * //advanced animations\n * .my-form {\n *   transition:0.5s linear all;\n *   background: white;\n * }\n * .my-form.ng-invalid {\n *   background: red;\n *   color:white;\n * }\n * </pre>\n *\n * @example\n    <example name=\"ng-form\" deps=\"angular-animate.js\" animations=\"true\" fixBase=\"true\" module=\"formExample\">\n      <file name=\"index.html\">\n       <script>\n         angular.module('formExample', [])\n           .controller('FormController', ['$scope', function($scope) {\n             $scope.userType = 'guest';\n           }]);\n       </script>\n       <style>\n        .my-form {\n          transition:all linear 0.5s;\n          background: transparent;\n        }\n        .my-form.ng-invalid {\n          background: red;\n        }\n       </style>\n       <form name=\"myForm\" ng-controller=\"FormController\" class=\"my-form\">\n         userType: <input name=\"input\" ng-model=\"userType\" required>\n         <span class=\"error\" ng-show=\"myForm.input.$error.required\">Required!</span><br>\n         <code>userType = {{userType}}</code><br>\n         <code>myForm.input.$valid = {{myForm.input.$valid}}</code><br>\n         <code>myForm.input.$error = {{myForm.input.$error}}</code><br>\n         <code>myForm.$valid = {{myForm.$valid}}</code><br>\n         <code>myForm.$error.required = {{!!myForm.$error.required}}</code><br>\n        </form>\n      </file>\n      <file name=\"protractor.js\" type=\"protractor\">\n        it('should initialize to model', function() {\n          var userType = element(by.binding('userType'));\n          var valid = element(by.binding('myForm.input.$valid'));\n\n          expect(userType.getText()).toContain('guest');\n          expect(valid.getText()).toContain('true');\n        });\n\n        it('should be invalid if empty', function() {\n          var userType = element(by.binding('userType'));\n          var valid = element(by.binding('myForm.input.$valid'));\n          var userInput = element(by.model('userType'));\n\n          userInput.clear();\n          userInput.sendKeys('');\n\n          expect(userType.getText()).toEqual('userType =');\n          expect(valid.getText()).toContain('false');\n        });\n      </file>\n    </example>\n *\n * @param {string=} name Name of the form.

Model binding,\n   * validation and number parsing are nevertheless supported.\n   *\n   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`\n   * in a way that never allows the input to hold an invalid value. That means:\n   * - any non-numerical value is set to `(max + min) / 2`.\n   * - any numerical value that is less than the current min val, or greater than the current max val\n   * is set to the min / max val respectively.\n   * - additionally, the current `step` is respected, so the nearest value that satisfies a step\n   * is used.\n   *\n   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))\n   * for more info.\n   *\n   * This has the following consequences for Angular:\n   *\n   * Since the element value should always reflect the current model value, a range input\n   * will set the bound ngModel expression to the value that the browser has set for the\n   * input element. For example, in the following input `<input type=\"range\" ng-model=\"model.value\">`,\n   * if the application sets `model.value = null`, the browser will set the input to `'50'`.\n   * Angular will then set the model to `50`, to prevent input and model value being out of sync.\n   *\n   * That means the model for range will immediately be set to `50` after `ngModel` has been\n   * initialized. It also means a range input can never have the required error.\n   *\n   * This does not only affect changes to the model value, but also to the values of the `min`,\n   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify\n   * the input value, Angular will also update the model value.\n   *\n   * Automatic value adjustment also means that a range input element can never have the `required`,\n   * `min`, or `max` errors.\n   *\n   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems\n   * when the step value changes dynamically - they do not adjust the element value correctly, but\n   * instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step`\n   * error on the input, and set the model to `undefined`.\n   *\n   * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do\n   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust\n   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.\n   *\n   * @param {string}  ngModel Assignable angular expression to data-bind to.\n   * @param {string=} name Property name of the form under which the control is published.\n   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater\n   *                  than `min`.

This is a key aspect of how angular\n * supports the principles behind the Model-View-Controller design pattern.\n *\n * MVC components in angular:\n *\n * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties\n *   are accessed through bindings.\n * * View — The template (HTML with data bindings) that is rendered into the View.\n * * Controller — The `ngController` directive specifies a Controller class; the class contains business\n *   logic behind the application to decorate the scope with functions and values\n *\n * Note that you can also attach controllers to the DOM by declaring it in a route definition\n * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller\n * again using `ng-controller` in the template itself.  This will cause the controller to be attached\n * and executed twice.\n *\n * @element ANY\n * @scope\n * @priority 500\n * @param {expression} ngController Name of a constructor function registered with the current\n * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}\n * that on the current scope evaluates to a constructor function.\n *\n * The controller instance can be published into a scope property by specifying\n * `ng-controller=\"as propertyName\"`.\n *\n * If the current `$controllerProvider` is configured to use globals (via\n * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may\n * also be the name of a globally accessible constructor function (deprecated, not recommended).\n *\n * @example\n * Here is a simple form for editing user contact information. Adding, removing, clearing, and\n * greeting are methods declared on the controller (see source tab). These methods can\n * easily be called from the angular markup. Any changes to the data are automatically reflected\n * in the View without the need for a manual update.\n *\n * Two different declaration styles are included below:\n *\n * * one binds methods and properties directly onto the controller using `this`:\n * `ng-controller=\"SettingsController1 as settings\"`\n * * one injects `$scope` into the controller:\n * `ng-controller=\"SettingsController2\"`\n *\n * The second option is more common in the Angular community, and is generally used in boilerplates\n * and in this guide. However, there are advantages to binding properties directly to the controller\n * and avoiding scope.\n *\n * * Using `controller as` makes it obvious which controller you are accessing in the template when\n * multiple controllers apply to an element.\n * * If you are writing your controllers as classes you have easier access to the properties and\n * methods, which will appear on the scope, from inside the controller code.\n * * Since there is always a `.` in the bindings, you don't have to worry about prototypal\n * inheritance masking primitives.\n *\n * This example demonstrates the `controller as` syntax.\n *\n * <example name=\"ngControllerAs\" module=\"controllerAsExample\">\n *   <file name=\"index.html\">\n *    <div id=\"ctrl-as-exmpl\"

(This CSP rule can be\n * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would\n * weaken the protections offered by CSP.)\n *\n * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.\n * This prevents apps from injecting custom styles directly into the document. Angular makes use of\n * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these\n * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`\n * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but\n * it is generally not recommended as it would weaken the protections offered by CSP.)\n *\n * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking dynamic code\n * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically\n * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a\n * CSP error to be logged in the console:\n *\n * ```\n * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of\n * script in the following Content Security Policy directive: \"default-src 'self'\". Note that\n * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.\n * ```\n *\n * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`\n * directive on an element of the HTML document that appears before the `<script>` tag that loads\n * the `angular.js` file.\n *\n * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*\n *\n * You can specify which of the CSP related Angular features should be deactivated by providing\n * a value for the `ng-csp` attribute. The options are as follows:\n *\n * * no-inline-style: this stops Angular from injecting CSS styles into the DOM\n *\n * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings\n *\n * You can use these values in the following combinations:\n *\n *\n * * No declaration means that Angular will assume that you can do inline styles, but it will do\n * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous\n * versions of Angular.\n *\n * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline\n * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous\n * versions of Angular.\n *\n * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can\n * inject inline styles. E.g. `<body ng-csp=\"no-unsafe-eval\">`.\n *\n * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can\n * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp=\"no-inline-style\">`\n *\n * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject\n * styles nor use eval, which is the same as an empty: ng-csp.\n * E.g.`<body ng-csp=\"no-inline-style;no-unsafe-eval\">`\n *\n * @example\n * This example shows how to apply the `ngCsp` directive to the `html` tag.\n   ```html\n     <!doctype html>\n     <html ng-app ng-csp>\n     ...\n     ...\n     </html>\n   ```\n  * @example\n      <!-- Note: the `.csp` suffix in the example name triggers CSP mode in our http server! -->\n      <example name=\"example.csp\" module=\"cspExample\" ng-csp=\"true\">\n        <file name=\"index.html\">\n          <div ng-controller=\"MainController as ctrl\">\n            <div>\n              <button ng-click=\"ctrl.inc()\" id=\"inc\">Increment</button>\n              <span id=\"counter\">\n                {{ctrl.counter}}\n              </span>\n            </div>\n\n            <div>\n              <button ng-click=\"ctrl.evil()\" id=\"evil\">Evil</button>\n              <span id=\"evilError\">\n                {{ctrl.evilError}}\n              </span>\n            </div>\n          </div>\n        </file>\n        <file name=\"script.js\">\n           angular.module('cspExample', [])\n             .controller('MainController', function MainController() {\n                this.counter = 0;\n                this.inc = function() {\n                  this.counter++;\n                };\n                this.evil = function() {\n                  try {\n                    eval('1+2'); // eslint-disable-line no-eval\n                  } catch (e) {\n                    this.evilError = e.message;\n                  }\n                };\n              });\n        </file>\n        <file name=\"protractor.js\" type=\"protractor\">\n          var util, webdriver;\n\n          var incBtn = element(by.id('inc'));\n          var counter = element(by.id('counter'));\n          var evilBtn = element(by.id('evil'));\n          var evilError = element(by.id('evilError'));\n\n          function getAndClearSevereErrors() {\n            return browser.manage().logs().get('browser').then(function(browserLog) {\n              return browserLog.filter(function(logEntry) {\n                return logEntry.level.value > webdriver.logging.Level.WARNING.value;\n              });\n            });\n          }\n\n          function clearErrors() {\n            getAndClearSevereErrors();\n          }\n\n          function expectNoErrors() {\n            getAndClearSevereErrors().then(function(filteredLog) {\n              expect(filteredLog.length).toEqual(0);\n              if (filteredLog.length) {\n                console.log('browser console errors: ' + util.inspect(filteredLog));\n              }\n            });\n          }\n\n          function expectError(regex) {\n            getAndClearSevereErrors().then(function(filteredLog) {\n              var found = false;\n              filteredLog.forEach(function(log) {\n                if (log.message.match(regex)) {\n                  found = true;\n                }\n              });\n              if (!found) {\n                throw new Error('expected an error that matches ' + regex);\n              }\n            });\n          }\n\n          beforeEach(function() {\n            util = require('util');\n            webdriver = require('selenium-webdriver');\n          });\n\n          // For now, we only test on Chrome,\n          // as Safari does not load the page with Protractor's injected scripts,\n          // and Firefox webdriver always disables content security policy (#6358)\n          if (browser.params.browser !== 'chrome') {\n            return;\n          }\n\n          it('should not report errors when the page is loaded', function() {\n            // clear errors so we are not dependent on previous tests\n            clearErrors();\n            // Need to reload the page as the page is already loaded when\n            // we come here\n            browser.driver.getCurrentUrl().then(function(url) {\n              browser.get(url);\n            });\n            expectNoErrors();\n          });\n\n          it('should evaluate expressions', function() {\n            expect(counter.getText()).toEqual('0');\n            incBtn.click();\n            expect(counter.getText()).toEqual('1');\n            expectNoErrors();\n          });\n\n          it('should throw and report an error when using \"eval\"', function() {\n            evilBtn.click();\n            expect(evilError.getText()).toMatch(/Content Security Policy/);\n            expectError(/Content Security Policy/);\n          });\n        </file>\n      </example>\n  */\n\n// `ngCsp` is not implemented as a proper directive any more, because we need it be processed while\n// we bootstrap the app (before `$parse` is instantiated).

If the expression assigned to `ngIf` evaluates to a false\n * value then the element is removed from the DOM, otherwise a clone of the\n * element is reinserted into the DOM.\n *\n * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the\n * element in the DOM rather than changing its visibility via the `display` css property.  A common\n * case when this difference is significant is when using css selectors that rely on an element's\n * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.\n *\n * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope\n * is created when the element is restored.  The scope created within `ngIf` inherits from\n * its parent scope using\n * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).\n * An important implication of this is if `ngModel` is used within `ngIf` to bind to\n * a javascript primitive defined in the parent scope. In this case any modifications made to the\n * variable within the child scope will override (hide) the value in the parent scope.\n *\n * Also, `ngIf` recreates elements using their compiled state. An example of this behavior\n * is if an element's class attribute is directly modified after it's compiled, using something like\n * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element\n * the added class will be lost because the original compiled state is used to regenerate the element.\n *\n * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`\n * and `leave` effects.\n *\n * @animations\n * | Animation                        | Occurs                               |\n * |----------------------------------|-------------------------------------|\n * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |\n * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |\n *\n * @element ANY\n * @scope\n * @priority 600\n * @param {expression} ngIf If the {@link guide/expression expression} is falsy then\n *     the element is removed from the DOM tree. If it is truthy a copy of the compiled\n *     element is added to the DOM tree.\n *\n * @example\n  <example module=\"ngAnimate\" deps=\"angular-animate.js\" animations=\"true\" name=\"ng-if\">\n    <file name=\"index.html\">\n      <label>Click me: <input type=\"checkbox\" ng-model=\"checked\" ng-init=\"checked=true\" /></label><br/>\n      Show when checked:\n      <span ng-if=\"checked\" class=\"animate-if\">\n        This is removed when the checkbox is unchecked.\n      </span>\n    </file>\n    <file name=\"animations.css\">\n      .animate-if {\n        background:white;\n        border:1px solid black;\n        padding:10px;\n      }\n\n      .animate-if.ng-enter, .animate-if.ng-leave {\n        transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;\n      }\n\n      .animate-if.ng-enter,\n      .animate-if.ng-leave.ng-leave-active {\n        opacity:0;\n      }\n\n      .animate-if.ng-leave,\n      .animate-if.ng-enter.ng-enter-active {\n        opacity:1;\n      }\n    </file>\n  </example>\n */\nvar ngIfDirective = ['$animate', '$compile', function($animate, $compile) {\n  return {\n    multiElement: true,\n    transclude: 'element',\n    priority: 600,\n    terminal: true,\n    restrict: 'A',\n    $$tlb: true,\n    link: function($scope, $element, $attr, ctrl, $transclude) {\n        var block, childScope, previousElements;\n        $scope.$watch($attr.ngIf, function ngIfWatchAction(value) {\n\n          if (value) {\n            if (!childScope) {\n              $transclude(function(clone, newScope) {\n                childScope = newScope;\n                clone[clone.length++] = $compile.$$createComment('end ngIf', $attr.ngIf);\n                // Note: We only need the first/last node of the cloned nodes.\n                // However, we need to keep the reference to the jqlite wrapper as it might be changed later\n                // by a directive with templateUrl when its template arrives.\n                block = {\n                  clone: clone\n                };\n                $animate.enter(clone, $element.parent(), $element);\n              });\n            }\n          } else {\n            if (previousElements) {\n              previousElements.remove();\n              previousElements = null;\n            }\n            if (childScope) {\n              childScope.$destroy();\n              childScope = null;\n            }\n            if (block) {\n              previousElements = getBlockNodes(block.clone);\n              $animate.leave(previousElements).done(function(response) {\n                if (response !== false) previousElements = null;\n              });\n              block = null;\n            }\n          }\n        });\n    }\n  };\n}];\n\n/**\n * @ngdoc directive\n * @name ngInclude\n * @restrict ECA\n *\n * @description\n * Fetches, compiles and includes an external HTML fragment.\n *\n * By default, the template URL is restricted to the same domain and protocol as the\n * application document.

This implies that the user of the directive is responsible for\n *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a\n *   tab or newline character.\n * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected\n *   when joining the list items back together) and whitespace around each list item is stripped\n *   before it is added to the model.\n *\n * ### Example with Validation\n *\n * <example name=\"ngList-directive\" module=\"listExample\">\n *   <file name=\"app.js\">\n *      angular.module('listExample', [])\n *        .controller('ExampleController', ['$scope', function($scope) {\n *          $scope.names = ['morpheus', 'neo', 'trinity'];\n *        }]);\n *   </file>\n *   <file name=\"index.html\">\n *    <form name=\"myForm\" ng-controller=\"ExampleController\">\n *      <label>List: <input name=\"namesInput\" ng-model=\"names\" ng-list required></label>\n *      <span role=\"alert\">\n *        <span class=\"error\" ng-show=\"myForm.namesInput.$error.required\">\n *        Required!</span>\n *      </span>\n *      <br>\n *      <tt>names = {{names}}</tt><br/>\n *      <tt>myForm.namesInput.$valid = {{myForm.namesInput.$valid}}</tt><br/>\n *      <tt>myForm.namesInput.$error = {{myForm.namesInput.$error}}</tt><br/>\n *      <tt>myForm.$valid = {{myForm.$valid}}</tt><br/>\n *      <tt>myForm.$error.required = {{!!myForm.$error.required}}</tt><br/>\n *     </form>\n *   </file>\n *   <file name=\"protractor.js\" type=\"protractor\">\n *     var listInput = element(by.model('names'));\n *     var names = element(by.exactBinding('names'));\n *     var valid = element(by.binding('myForm.namesInput.$valid'));\n *     var error = element(by.css('span.error'));\n *\n *     it('should initialize to model', function() {\n *       expect(names.getText()).toContain('[\"morpheus\",\"neo\",\"trinity\"]');\n *       expect(valid.getText()).toContain('true');\n *       expect(error.getCssValue('display')).toBe('none');\n *     });\n *\n *     it('should be invalid if empty', function() {\n *       listInput.clear();\n *       listInput.sendKeys('');\n *\n *       expect(names.getText()).toContain('');\n *       expect(valid.getText()).toContain('false');\n *       expect(error.getCssValue('display')).not.toBe('none');\n *     });\n *   </file>\n * </example>\n *\n * ### Example - splitting on newline\n * <example name=\"ngList-directive-newlines\">\n *   <file name=\"index.html\">\n *    <textarea ng-model=\"list\" ng-list=\"&#10;\" ng-trim=\"false\"></textarea>\n *    <pre>{{ list | json }}</pre>\n *   </file>\n *   <file name=\"protractor.js\" type=\"protractor\">\n *     it(\"should split the text by newlines\", function() {\n *       var listInput = element(by.model('list'));\n *       var output = element(by.binding('list | json'));\n *       listInput.sendKeys('abc\\ndef\\nghi');\n *       expect(output.getText()).toContain('[\\n  \"abc\",\\n  \"def\",\\n  \"ghi\"\\n]');\n *     });\n *   </file>\n * </example>\n *\n * @element input\n * @param {string=} ngList optional delimiter that should be used to split the value.\n */\nvar ngListDirective = function() {\n  return {\n    restrict: 'A',\n    priority: 100,\n    require: 'ngModel',\n    link: function(scope, element, attr, ctrl) {\n      var ngList = attr.ngList || ', ';\n      var trimValues = attr.ngTrim !== 'false';\n      var separator = trimValues ?

It purposefully does not contain any logic which deals with DOM rendering or\n * listening to DOM events.\n * Such DOM related logic should be provided by other directives which make use of\n * `NgModelController` for data-binding to control elements.\n * Angular provides this DOM logic for most {@link input `input`} elements.\n * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example\n * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.\n *\n * @example\n * ### Custom Control Example\n * This example shows how to use `NgModelController` with a custom control to achieve\n * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)\n * collaborate together to achieve the desired result.\n *\n * `contenteditable` is an HTML5 attribute, which tells the browser to let the element\n * contents be edited in place by the user.\n *\n * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}\n * module to automatically remove \"bad\" content like inline event listener (e.g. `<span onclick=\"...\">`).\n * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks\n * that content using the `$sce` service.\n *\n * <example name=\"NgModelController\" module=\"customControl\" deps=\"angular-sanitize.js\">\n    <file name=\"style.css\">\n      [contenteditable] {\n        border: 1px solid black;\n        background-color: white;\n        min-height: 20px;\n      }\n\n      .ng-invalid {\n        border: 1px solid red;\n      }\n\n    </file>\n    <file name=\"script.js\">\n      angular.module('customControl', ['ngSanitize']).\n        directive('contenteditable', ['$sce', function($sce) {\n          return {\n            restrict: 'A', // only activate on element attribute\n            require: '?ngModel', // get a hold of NgModelController\n            link: function(scope, element, attrs, ngModel) {\n              if (!ngModel) return;

If only properties of the\n * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.\n *\n * The model must be assigned an entirely new object or collection before a re-rendering will occur.\n *\n * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression\n * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or\n * if the select is given the `multiple` attribute.\n *\n * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the\n * first level of the object (or only changing the properties of an item in the collection if it's an array) will still\n * not trigger a re-rendering of the model.\n *\n * # CSS classes\n * The following CSS classes are added and removed on the associated input/select/textarea element\n * depending on the validity of the model.\n *\n *  - `ng-valid`: the model is valid\n *  - `ng-invalid`: the model is invalid\n *  - `ng-valid-[key]`: for each valid key added by `$setValidity`\n *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`\n *  - `ng-pristine`: the control hasn't been interacted with yet\n *  - `ng-dirty`: the control has been interacted with\n *  - `ng-touched`: the control has been blurred\n *  - `ng-untouched`: the control hasn't been blurred\n *  - `ng-pending`: any `$asyncValidators` are unfulfilled\n *  - `ng-empty`: the view does not contain a value or the value is deemed \"empty\", as defined\n *     by the {@link ngModel.NgModelController#$isEmpty} method\n *  - `ng-not-empty`: the view contains a non-empty value\n *\n * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n *\n * ## Animation Hooks\n *\n * Animations within models are triggered when any of the associated CSS classes are added and removed\n * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,\n * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.\n * The animations that are triggered within ngModel are similar to how they work in ngClass and\n * animations can be hooked into using CSS transitions, keyframes as well as JS animations.\n *\n * The following example shows a simple way to utilize CSS transitions to style an input element\n * that has been rendered as invalid after it has been validated:\n *\n * <pre>\n * //be sure to include ngAnimate as a module to hook into more\n * //advanced animations\n * .my-input {\n *   transition:0.5s linear all;\n *   background: white;\n * }\n * .my-input.ng-invalid {\n *   background: red;\n *   color:white;\n * }\n * </pre>\n *\n * @example\n * <example deps=\"angular-animate.js\" animations=\"true\" fixBase=\"true\" module=\"inputExample\" name=\"ng-model\">\n     <file name=\"index.html\">\n       <script>\n        angular.module('inputExample', [])\n          .controller('ExampleController', ['$scope', function($scope) {\n            $scope.val = '1';\n          }]);\n       </script>\n       <style>\n         .my-input {\n           transition:all linear 0.5s;\n           background: transparent;\n         }\n         .my-input.ng-invalid {\n           color:white;\n           background: red;\n         }\n       </style>\n       <p id=\"inputDescription\">\n        Update input to see transitions when valid/invalid.\n        Integer is a valid value.\n       </p>\n       <form name=\"testForm\" ng-controller=\"ExampleController\">\n         <input ng-model=\"val\" ng-pattern=\"/^\\d+$/\" name=\"anim\" class=\"my-input\"\n                aria-describedby=\"inputDescription\" />\n       </form>\n     </file>\n * </example>\n *\n * ## Binding to a getter/setter\n *\n * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a\n * function that returns a representation of the model when called with zero arguments, and sets\n * the internal state of a model when called with an argument. It's sometimes useful to use this\n * for models that have an internal representation that's different from what the model exposes\n * to the view.\n *\n * <div class=\"alert alert-success\">\n * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more\n * frequently than other parts of your code.\n * </div>\n *\n * You use this behavior by adding `ng-model-options=\"{ getterSetter: true }\"` to an element that\n * has `ng-model` attached to it. You can also add `ng-model-options=\"{ getterSetter: true }\"` to\n * a `<form>`, which will enable this behavior for all `<input>`s within it. See\n * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.\n *\n * The following example shows how to use `ngModel` with a getter/setter:\n *\n * @example\n * <example name=\"ngModel-getter-setter\" module=\"getterSetterExample\">\n     <file name=\"index.html\">\n       <div ng-controller=\"ExampleController\">\n         <form name=\"userForm\">\n           <label>Name:\n             <input type=\"text\" name=\"userName\"\n                    ng-model=\"user.name\"\n                    ng-model-options=\"{ getterSetter: true }\" />\n           </label>\n         </form>\n         <pre>user.name = <span ng-bind=\"user.name()\"></span></pre>\n       </div>\n     </file>\n     <file name=\"app.js\">\n       angular.module('getterSetterExample', [])\n         .controller('ExampleController', ['$scope', function($scope) {\n           var _name = 'Brian';\n           $scope.user = {\n             name: function(newName) {\n              // Note that newName can be undefined for two reasons:\n              // 1. Because it is called as a getter and thus called with no arguments\n              // 2. Because the property should actually be set to undefined. This happens e.g. if the\n              //    input is invalid\n              return arguments.length ? (_name = newName) : _name;\n             }\n           };\n         }]);\n     </file>\n * </example>\n */\nvar ngModelDirective = ['$rootScope', function($rootScope) {\n  return {\n    restrict: 'A',\n    require: ['ngModel', '^?form', '^?ngModelOptions'],\n    controller: NgModelController,\n    // Prelink needs to run before any input directive\n    // so that we can set the NgModelOptions in NgModelController\n    // before anyone else uses it.\n    priority: 1,\n    compile: function ngModelCompile(element) {\n      // Setup initial state of the control\n      element.addClass(PRISTINE_CLASS).addClass(UNTOUCHED_CLASS).addClass(VALID_CLASS);\n\n      return {\n        pre: function ngModelPreLink(scope, element, attr, ctrls) {\n          var modelCtrl = ctrls[0],\n              formCtrl = ctrls[1] || modelCtrl.$$parentForm,\n              optionsCtrl = ctrls[2];\n\n          if (optionsCtrl) {\n            modelCtrl.$options = optionsCtrl.$options;\n          }\n\n          modelCtrl.$$initGetterSetters();\n\n          // notify others, especially parent forms\n          formCtrl.$addControl(modelCtrl);\n\n          attr.$observe('name', function(newValue) {\n            if (modelCtrl.$name !== newValue) {\n              modelCtrl.$$parentForm.$$renameControl(modelCtrl, newValue);\n            }\n          });\n\n          scope.$on('$destroy', function() {\n            modelCtrl.$$parentForm.$removeControl(modelCtrl);\n          });\n        },\n        post: function ngModelPostLink(scope, element, attr, ctrls) {\n          var modelCtrl = ctrls[0];\n          if (modelCtrl.$options.getOption('updateOn')) {\n            element.on(modelCtrl.$options.getOption('updateOn'), function(ev) {\n              modelCtrl.$$debounceViewValueCommit(ev && ev.type);\n            });\n          }\n\n          function setTouched() {\n            modelCtrl.$setTouched();\n          }\n\n          element.on('blur', function() {\n            if (modelCtrl.$touched) return;\n\n            if ($rootScope.$$phase) {\n              scope.$evalAsync(setTouched);\n            } else {\n              scope.$apply(setTouched);\n            }\n          });\n        }\n      };\n    }\n  };\n}];\n\n/* exported defaultModelOptions */\nvar defaultModelOptions;\nvar DEFAULT_REGEXP = /(\\s+|^)default(\\s+|$)/;\n\n/**\n * @ngdoc type\n * @name ModelOptions\n * @description\n * A container for the options set by the {@link ngModelOptions} directive\n */\nfunction ModelOptions(options) {\n  this.$$options = options;\n}\n\nModelOptions.prototype = {\n\n  /**\n   * @ngdoc method\n   * @name ModelOptions#getOption\n   * @param {string} name the name of the option to retrieve\n   * @returns {*} the value of the option\n   * @description\n   * Returns the value of the given option\n   */\n  getOption: function(name) {\n    return this.$$options[name];\n  },\n\n  /**\n   * @ngdoc method\n   * @name ModelOptions#createChild\n   * @param {Object} options a hash of options for the new child that will override the parent's options\n   * @return {ModelOptions} a new `ModelOptions` object initialized with the given options.\n   */\n  createChild: function(options) {\n    var inheritAll = false;\n\n    // make a shallow copy\n    options = extend({}, options);\n\n    // Inherit options from the parent if specified by the value `\"$inherit\"`\n    forEach(options, /* @this */ function(option, key) {\n      if (option === '$inherit') {\n        if (key === '*') {\n          inheritAll = true;\n        } else {\n          options[key] = this.$$options[key];\n          // `updateOn` is special so we must also inherit the `updateOnDefault` option\n          if (key === 'updateOn') {\n            options.updateOnDefault = this.$$options.updateOnDefault;\n          }\n        }\n      } else {\n        if (key === 'updateOn') {\n          // If the `updateOn` property contains the `default` event then we have to remove\n          // it from the event list and set the `updateOnDefault` flag.\n          options.updateOnDefault = false;\n          options[key] = trim(option.replace(DEFAULT_REGEXP, function() {\n            options.updateOnDefault = true;\n            return ' ';\n          }));\n        }\n      }\n    }, this);\n\n    if (inheritAll) {\n      // We have a property of the form: `\"*\": \"$inherit\"`\n      delete options['*'];\n      defaults(options, this.$$options);\n    }\n\n    // Finally add in any missing defaults\n    defaults(options, defaultModelOptions.$$options);\n\n    return new ModelOptions(options);\n  }\n};\n\n\ndefaultModelOptions = new ModelOptions({\n  updateOn: '',\n  updateOnDefault: true,\n  debounce: 0,\n  getterSetter: false,\n  allowInvalid: false,\n  timezone: null\n});\n\n\n/**\n * @ngdoc directive\n * @name ngModelOptions\n *\n * @description\n * This directive allows you to modify the behaviour of {@link ngModel} directives within your\n * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}\n * directives will use the options of their nearest `ngModelOptions` ancestor.\n *\n * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as\n * an Angular expression. This expression should evaluate to an object, whose properties contain\n * the settings. For example: `<div \"ng-model-options\"=\"{ debounce: 100 }\"`.\n *\n * ## Inheriting Options\n *\n * You can specify that an `ngModelOptions` setting should be inherited from a parent `ngModelOptions`\n * directive by giving it the value of `\"$inherit\"`.\n * Then it will inherit that setting from the first `ngModelOptions` directive found by traversing up the\n * DOM tree. If there is no ancestor element containing an `ngModelOptions` directive then default settings\n * will be used.\n *\n * For example given the following fragment of HTML\n *\n *\n * ```html\n * <div ng-model-options=\"{ allowInvalid: true, debounce: 200 }\">\n *   <form ng-model-options=\"{ updateOn: 'blur', allowInvalid: '$inherit' }\">\n *     <input ng-model-options=\"{ updateOn: 'default', allowInvalid: '$inherit' }\" />\n *   </form>\n * </div>\n * ```\n *\n * the `input` element will have the following settings\n *\n * ```js\n * { allowInvalid: true, updateOn: 'default', debounce: 0 }\n * ```\n *\n * Notice that the `debounce` setting was not inherited and used the default value instead.\n *\n * You can specify that all undefined settings are automatically inherited from an ancestor by\n * including a property with key of `\"*\"` and value of `\"$inherit\"`.\n *\n * For example given the following fragment of HTML\n *\n *\n * ```html\n * <div ng-model-options=\"{ allowInvalid: true, debounce: 200 }\">\n *   <form ng-model-options=\"{ updateOn: 'blur', \"*\": '$inherit' }\">\n *     <input ng-model-options=\"{ updateOn: 'default', \"*\": '$inherit' }\" />\n *   </form>\n * </div>\n * ```\n *\n * the `input` element will have the following settings\n *\n * ```js\n * { allowInvalid: true, updateOn: 'default', debounce: 200 }\n * ```\n *\n * Notice that the `debounce` setting now inherits the value from the outer `<div>` element.\n *\n * If you are creating a reusable component then you should be careful when using `\"*\": \"$inherit\"`\n * since you may inadvertently inherit a setting in the future that changes the behavior of your component.\n *\n *\n * ## Triggering and debouncing model updates\n *\n * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will\n * trigger a model update and/or a debouncing delay so that the actual update only takes place when\n * a timer expires; this timer will be reset after another change takes place.\n *\n * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might\n * be different from the value in the actual model. This means that if you update the model you\n * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in\n * order to make sure it is synchronized with the model and that any debounced action is canceled.\n *\n * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}\n * method is by making sure the input is placed inside a form that has a `name` attribute. This is\n * important because `form` controllers are published to the related scope under the name in their\n * `name` attribute.\n *\n * Any pending changes will take place immediately when an enclosing form is submitted via the\n * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n * to have access to the updated model.\n *\n * The following example shows how to override immediate updates. Changes on the inputs within the\n * form will update the model only when the control loses focus (blur event). If `escape` key is\n * pressed while the input field is focused, the value is reset to the value in the current model.\n *\n * <example name=\"ngModelOptions-directive-blur\" module=\"optionsExample\">\n *   <file name=\"index.html\">\n *     <div ng-controller=\"ExampleController\">\n *       <form name=\"userForm\">\n *         <label>\n *           Name:\n *           <input type=\"text\" name=\"userName\"\n *                  ng-model=\"user.name\"\n *                  ng-model-options=\"{ updateOn: 'blur' }\"\n *                  ng-keyup=\"cancel($event)\" />\n *         </label><br />\n *         <label>\n *           Other data:\n *           <input type=\"text\" ng-model=\"user.data\" />\n *         </label><br />\n *       </form>\n *       <pre>user.name = <span ng-bind=\"user.name\"></span></pre>\n *     </div>\n *   </file>\n *   <file name=\"app.js\">\n *     angular.module('optionsExample', [])\n *       .controller('ExampleController', ['$scope', function($scope) {\n *         $scope.user = { name: 'say', data: '' };\n *\n *         $scope.cancel = function(e) {\n *           if (e.keyCode === 27) {\n *             $scope.userForm.userName.$rollbackViewValue();\n *           }\n *         };\n *       }]);\n *   </file>\n *   <file name=\"protractor.js\" type=\"protractor\">\n *     var model = element(by.binding('user.name'));\n *     var input = element(by.model('user.name'));\n *     var other = element(by.model('user.data'));\n *\n *     it('should allow custom events', function() {\n *       input.sendKeys(' hello');\n *       input.click();\n *       expect(model.getText()).toEqual('say');\n *       other.click();\n *       expect(model.getText()).toEqual('say hello');\n *     });\n *\n *     it('should $rollbackViewValue when model changes', function() {\n *       input.sendKeys(' hello');\n *       expect(input.getAttribute('value')).toEqual('say hello');\n *       input.sendKeys(protractor.Key.ESCAPE);\n *       expect(input.getAttribute('value')).toEqual('say');\n *       other.click();\n *       expect(model.getText()).toEqual('say');\n *     });\n *   </file>\n * </example>\n *\n * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change.\n * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.\n *\n * <example name=\"ngModelOptions-directive-debounce\" module=\"optionsExample\">\n *   <file name=\"index.html\">\n *     <div ng-controller=\"ExampleController\">\n *       <form name=\"userForm\">\n *         Name:\n *         <input type=\"text\" name=\"userName\"\n *                ng-model=\"user.name\"\n *                ng-model-options=\"{ debounce: 1000 }\" />\n *         <button ng-click=\"userForm.userName.$rollbackViewValue(); user.name=''\">Clear</button><br />\n *       </form>\n *       <pre>user.name = <span ng-bind=\"user.name\"></span></pre>\n *     </div>\n *   </file>\n *   <file name=\"app.js\">\n *     angular.module('optionsExample', [])\n *       .controller('ExampleController', ['$scope', function($scope) {\n *         $scope.user = { name: 'say' };\n *       }]);\n *   </file>\n * </example>\n *\n * ## Model updates and validation\n *\n * The default behaviour in `ngModel` is that the model value is set to `undefined` when the\n * validation determines that the value is invalid. By setting the `allowInvalid` property to true,\n * the model will still be updated even if the value is invalid.\n *\n *\n * ## Connecting to the scope\n *\n * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression\n * on the scope refers to a \"getter/setter\" function rather than the value itself.\n *\n * The following example shows how to bind to getter/setters:\n *\n * <example name=\"ngModelOptions-directive-getter-setter\" module=\"getterSetterExample\">\n *   <file name=\"index.html\">\n *     <div ng-controller=\"ExampleController\">\n *       <form name=\"userForm\">\n *         <label>\n *           Name:\n *           <input type=\"text\" name=\"userName\"\n *                  ng-model=\"user.name\"\n *                  ng-model-options=\"{ getterSetter: true }\" />\n *         </label>\n *       </form>\n *       <pre>user.name = <span ng-bind=\"user.name()\"></span></pre>\n *     </div>\n *   </file>\n *   <file name=\"app.js\">\n *     angular.module('getterSetterExample', [])\n *       .controller('ExampleController', ['$scope', function($scope) {\n *         var _name = 'Brian';\n *         $scope.user = {\n *           name: function(newName) {\n *             return angular.isDefined(newName) ? (_name = newName) : _name;\n *           }\n *         };\n *       }]);\n *   </file>\n * </example>\n *\n *\n * ## Specifying timezones\n *\n * You can specify the timezone that date/time input directives expect by providing its name in the\n * `timezone` property.\n *\n * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and\n *   and its descendents. Valid keys are:\n *   - `updateOn`: string specifying which event should the input be bound to. You can set several\n *     events using an space delimited list. There is a special event called `default` that\n *     matches the default events belonging to the control.\n *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A\n *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a\n *     custom value for each event. For example:\n *     ```\n *     ng-model-options=\"{\n *       updateOn: 'default blur',\n *       debounce: { 'default': 500, 'blur': 0 }\n *     }\"\n *     ```\n *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did\n *     not validate correctly instead of the default behavior of setting the model to undefined.\n *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to\n *     `ngModel` as getters/setters.\n *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for\n *     `<input type=\"date\" />`, `<input type=\"time\" />`, ... .

However, `ngOptions` provides some benefits:\n * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the\n * comprehension expression\n * - reduced memory consumption by not creating a new scope for each repeated instance\n * - increased render speed by creating the options in a documentFragment instead of individually\n *\n * When an item in the `<select>` menu is selected, the array element or object property\n * represented by the selected option will be bound to the model identified by the `ngModel`\n * directive.\n *\n * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can\n * be nested into the `<select>` element. This element will then represent the `null` or \"not selected\"\n * option. See example below for demonstration.\n *\n * ## Complex Models (objects or collections)\n *\n * By default, `ngModel` watches the model by reference, not value. This is important to know when\n * binding the select to a model that is an object or a collection.\n *\n * One issue occurs if you want to preselect an option. For example, if you set\n * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,\n * because the objects are not identical. So by default, you should always reference the item in your collection\n * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.\n *\n * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity\n * of the item not by reference, but by the result of the `track by` expression. For example, if your\n * collection items have an id property, you would `track by item.id`.\n *\n * A different issue with objects or collections is that ngModel won't detect if an object property or\n * a collection item changes. For that reason, `ngOptions` additionally watches the model using\n * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.\n * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection\n * has not changed identity, but only a property on the object or an item in the collection changes.\n *\n * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection\n * if the model is an array). This means that changing a property deeper than the first level inside the\n * object/collection will not trigger a re-rendering.\n *\n * ## `select` **`as`**\n *\n * Using `select` **`as`** will bind the result of the `select` expression to the model, but\n * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)\n * or property name (for object data sources) of the value within the collection. If a **`track by`** expression\n * is used, the result of that expression will be set as the value of the `option` and `select` elements.\n *\n *\n * ### `select` **`as`** and **`track by`**\n *\n * <div class=\"alert alert-warning\">\n * Be careful when using `select` **`as`** and **`track by`** in the same expression.\n * </div>\n *\n * Given this array of items on the $scope:\n *\n * ```js\n * $scope.items = [{\n *   id: 1,\n *   label: 'aLabel',\n *   subItem: { name: 'aSubItem' }\n * }, {\n *   id: 2,\n *   label: 'bLabel',\n *   subItem: { name: 'bSubItem' }\n * }];\n * ```\n *\n * This will work:\n *\n * ```html\n * <select ng-options=\"item as item.label for item in items track by item.id\" ng-model=\"selected\"></select>\n * ```\n * ```js\n * $scope.selected = $scope.items[0];\n * ```\n *\n * but this will not work:\n *\n * ```html\n * <select ng-options=\"item.subItem as item.label for item in items track by item.id\" ng-model=\"selected\"></select>\n * ```\n * ```js\n * $scope.selected = $scope.items[0].subItem;\n * ```\n *\n * In both examples, the **`track by`** expression is applied successfully to each `item` in the\n * `items` array. Because the selected option has been set programmatically in the controller, the\n * **`track by`** expression is also applied to the `ngModel` value. In the first example, the\n * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with\n * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**\n * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value\n * is not matched against any `<option>` and the `<select>` appears as having no selected value.\n *\n *\n * @param {string} ngModel Assignable angular expression to data-bind to.\n * @param {string=} name Property name of the form under which the control is published.\n * @param {string=} required The control is considered valid only if value is entered.\n * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to\n *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of\n *    `required` when you want to data-bind to the `required` attribute.\n * @param {comprehension_expression=} ngOptions in one of the following forms:\n *\n *   * for array data sources:\n *     * `label` **`for`** `value` **`in`** `array`\n *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`\n *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`\n *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`\n *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`\n *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`\n *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`\n *        (for including a filter with `track by`)\n *   * for object data sources:\n *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`\n *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`\n *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`\n *     * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`\n *     * `select` **`as`** `label` **`group by`** `group`\n *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`\n *     * `select` **`as`** `label` **`disable when`** `disable`\n *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`\n *\n * Where:\n *\n *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.\n *   * `value`: local variable which will refer to each item in the `array` or each property value\n *      of `object` during iteration.\n *   * `key`: local variable which will refer to a property name in `object` during iteration.\n *   * `label`: The result of this expression will be the label for `<option>` element. The\n *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).\n *   * `select`: The result of this expression will be bound to the model of the parent `<select>`\n *      element. If not specified, `select` expression will default to `value`.\n *   * `group`: The result of this expression will be used to group options using the `<optgroup>`\n *      DOM element.\n *   * `disable`: The result of this expression will be used to disable the rendered `<option>`\n *      element. Return `true` to disable.\n *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be\n *      used to identify the objects in the array. The `trackexpr` will most likely refer to the\n *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved\n *      even when the options are recreated (e.g. reloaded from the server).\n *\n * @example\n    <example module=\"selectExample\" name=\"select\">\n      <file name=\"index.html\">\n        <script>\n        angular.module('selectExample', [])\n          .controller('ExampleController', ['$scope', function($scope) {\n            $scope.colors = [\n              {name:'black', shade:'dark'},\n              {name:'white', shade:'light', notAnOption: true},\n              {name:'red', shade:'dark'},\n              {name:'blue', shade:'dark', notAnOption: true},\n              {name:'yellow', shade:'light', notAnOption: false}\n            ];\n            $scope.myColor = $scope.colors[2]; // red\n          }]);\n        </script>\n        <div ng-controller=\"ExampleController\">\n          <ul>\n            <li ng-repeat=\"color in colors\">\n              <label>Name: <input ng-model=\"color.name\"></label>\n              <label><input type=\"checkbox\" ng-model=\"color.notAnOption\"> Disabled?</label>\n              <button ng-click=\"colors.splice($index, 1)\" aria-label=\"Remove\">X</button>\n            </li>\n            <li>\n              <button ng-click=\"colors.push({})\">add</button>\n            </li>\n          </ul>\n          <hr/>\n          <label>Color (null not allowed):\n            <select ng-model=\"myColor\" ng-options=\"color.name for color in colors\"></select>\n          </label><br/>\n          <label>Color (null allowed):\n          <span  class=\"nullable\">\n            <select ng-model=\"myColor\" ng-options=\"color.name for color in colors\">\n              <option value=\"\">-- choose color --</option>\n            </select>\n          </span></label><br/>\n\n          <label>Color grouped by shade:\n            <select ng-model=\"myColor\" ng-options=\"color.name group by color.shade for color in colors\">\n            </select>\n          </label><br/>\n\n          <label>Color grouped by shade, with some disabled:\n            <select ng-model=\"myColor\"\n                  ng-options=\"color.name group by color.shade disable when color.notAnOption for color in colors\">\n            </select>\n          </label><br/>\n\n\n\n          Select <button ng-click=\"myColor = { name:'not in list', shade: 'other' }\">bogus</button>.\n          <br/>\n          <hr/>\n          Currently selected: {{ {selected_color:myColor} }}\n          <div style=\"border:solid 1px black; height:20px\"\n               ng-style=\"{'background-color':myColor.name}\">\n          </div>\n        </div>\n      </file>\n      <file name=\"protractor.js\" type=\"protractor\">\n         it('should check ng-options', function() {\n           expect(element(by.binding('{selected_color:myColor}')).getText()).toMatch('red');\n           element.all(by.model('myColor')).first().click();\n           element.all(by.css('select[ng-model=\"myColor\"] option')).first().click();\n           expect(element(by.binding('{selected_color:myColor}')).getText()).toMatch('black');\n           element(by.css('.nullable select[ng-model=\"myColor\"]')).click();\n           element.all(by.css('.nullable select[ng-model=\"myColor\"] option')).first().click();\n           expect(element(by.binding('{selected_color:myColor}')).getText()).toMatch('null');\n         });\n      </file>\n    </example>\n */\n\n/* eslint-disable max-len */\n//                     //00001111111111000000000002222222222000000000000000000000333333333300000000000000000000000004444444444400000000000005555555555555000000000666666666666600000007777777777777000000000000000888888888800000000000000000009999999999\nvar NG_OPTIONS_REGEXP = /^\\s*([\\s\\S]+?)(?:\\s+as\\s+([\\s\\S]+?))?(?:\\s+group\\s+by\\s+([\\s\\S]+?))?(?:\\s+disable\\s+when\\s+([\\s\\S]+?))?\\s+for\\s+(?:([$\\w][$\\w]*)|(?:\\(\\s*([$\\w][$\\w]*)\\s*,\\s*([$\\w][$\\w]*)\\s*\\)))\\s+in\\s+([\\s\\S]+?)(?:\\s+track\\s+by\\s+([\\s\\S]+?))?$/;\n                        // 1: value expression (valueFn)\n                        // 2: label expression (displayFn)\n                        // 3: group by expression (groupByFn)\n                        // 4: disable when expression (disableWhenFn)\n                        // 5: array item variable name\n                        // 6: object item key variable name\n                        // 7: object item value variable name\n                        // 8: collection expression\n                        // 9: track by expression\n/* eslint-enable */\n\n\nvar ngOptionsDirective = ['$compile', '$document', '$parse', function($compile, $document, $parse) {\n\n  function parseOptionsExpression(optionsExp, selectElement, scope) {\n\n    var match = optionsExp.match(NG_OPTIONS_REGEXP);\n    if (!(match)) {\n      throw ngOptionsMinErr('iexp',\n        'Expected expression in form of ' +\n        '\\'_select_ (as _label_)? for (_key_,)?_value_ in _collection_\\'' +\n        ' but got \\'{0}\\'.

You configure ngPluralize directive\n * by specifying the mappings between\n * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)\n * and the strings to be displayed.\n *\n * # Plural categories and explicit number rules\n * There are two\n * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)\n * in Angular's default en-US locale: \"one\" and \"other\".\n *\n * While a plural category may match many numbers (for example, in en-US locale, \"other\" can match\n * any number that is not 1), an explicit number rule can only match one number. For example, the\n * explicit number rule for \"3\" matches the number 3. There are examples of plural categories\n * and explicit number rules throughout the rest of this documentation.\n *\n * # Configuring ngPluralize\n * You configure ngPluralize by providing 2 attributes: `count` and `when`.\n * You can also provide an optional attribute, `offset`.\n *\n * The value of the `count` attribute can be either a string or an {@link guide/expression\n * Angular expression}; these are evaluated on the current scope for its bound value.\n *\n * The `when` attribute specifies the mappings between plural categories and the actual\n * string to be displayed. The value of the attribute should be a JSON object.\n *\n * The following example shows how to configure ngPluralize:\n *\n * ```html\n * <ng-pluralize count=\"personCount\"\n                 when=\"{'0': 'Nobody is viewing.',\n *                      'one': '1 person is viewing.',\n *                      'other': '{} people are viewing.'}\">\n * </ng-pluralize>\n *```\n *\n * In the example, `\"0: Nobody is viewing.\"` is an explicit number rule. If you did not\n * specify this rule, 0 would be matched to the \"other\" category and \"0 people are viewing\"\n * would be shown instead of \"Nobody is viewing\". You can specify an explicit number rule for\n * other numbers, for example 12, so that instead of showing \"12 people are viewing\", you can\n * show \"a dozen people are viewing\".\n *\n * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted\n * into pluralized strings. In the previous example, Angular will replace `{}` with\n * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder\n * for <span ng-non-bindable>{{numberExpression}}</span>.\n *\n * If no rule is defined for a category, then an empty string is displayed and a warning is generated.\n * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.\n *\n * # Configuring ngPluralize with offset\n * The `offset` attribute allows further customization of pluralized text, which can result in\n * a better user experience. For example, instead of the message \"4 people are viewing this document\",\n * you might display \"John, Kate and 2 others are viewing this document\".\n * The offset attribute allows you to offset a number by any desired value.\n * Let's take a look at an example:\n *\n * ```html\n * <ng-pluralize count=\"personCount\" offset=2\n *               when=\"{'0': 'Nobody is viewing.',\n *                      '1': '{{person1}} is viewing.',\n *                      '2': '{{person1}} and {{person2}} are viewing.',\n *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',\n *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}\">\n * </ng-pluralize>\n * ```\n *\n * Notice that we are still using two plural categories(one, other), but we added\n * three explicit number rules 0, 1 and 2.\n * When one person, perhaps John, views the document, \"John is viewing\" will be shown.\n * When three people view the document, no explicit number rule is found, so\n * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.\n * In this case, plural category 'one' is matched and \"John, Mary and one other person are viewing\"\n * is shown.\n *\n * Note that when you specify offsets, you must provide explicit number rules for\n * numbers from 0 up to and including the offset. If you use an offset of 3, for example,\n * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for\n * plural categories \"one\" and \"other\".\n *\n * @param {string|expression} count The variable to be bound to.\n * @param {string} when The mapping between plural category to its corresponding strings.\n * @param {number=} offset Offset to deduct from the total number.\n *\n * @example\n    <example module=\"pluralizeExample\" name=\"ng-pluralize\">\n

Browsers generally follow the strategy of providing\n *   keys in the order in which they were defined, although there are exceptions when keys are deleted\n *   and reinstated. See the\n *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).\n *\n * - `ngRepeat` will silently *ignore* object keys starting with `$`, because\n *   it's a prefix used by Angular for public (`$`) and private (`$$`) properties.\n *\n * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with\n *   objects, and will throw an error if used with one.\n *\n * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array\n * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could\n * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)\n * or implement a `$watch` on the object yourself.\n *\n *\n * # Tracking and Duplicates\n *\n * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in\n * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n *\n * To minimize creation of DOM elements, `ngRepeat` uses a function\n * to \"keep track\" of all items in the collection and their corresponding DOM elements.\n * For example, if an item is added to the collection, `ngRepeat` will know that all other items\n * already have DOM elements, and will not re-render them.\n *\n * The default tracking function (which tracks items by their identity) does not allow\n * duplicate items in arrays. This is because when there are duplicates, it is not possible\n * to maintain a one-to-one mapping between collection items and DOM elements.\n *\n * If you do need to repeat duplicate items, you can substitute the default tracking behavior\n * with your own using the `track by` expression.\n *\n * For example, you may track items by the index of each item in the collection, using the\n * special scope property `$index`:\n * ```html\n *    <div ng-repeat=\"n in [42, 42, 43, 43] track by $index\">\n *      {{n}}\n *    </div>\n * ```\n *\n * You may also use arbitrary expressions in `track by`, including references to custom functions\n * on the scope:\n * ```html\n *    <div ng-repeat=\"n in [42, 42, 43, 43] track by myTrackingFunction(n)\">\n *      {{n}}\n *    </div>\n * ```\n *\n * <div class=\"alert alert-success\">\n * If you are working with objects that have a unique identifier property, you should track\n * by this identifier instead of the object instance. Should you reload your data later, `ngRepeat`\n * will not have to rebuild the DOM elements for items it has already rendered, even if the\n * JavaScript objects in the collection have been substituted for new ones. For large collections,\n * this significantly improves rendering performance. If you don't have a unique identifier,\n * `track by $index` can also provide a performance boost.\n * </div>\n *\n * ```html\n *    <div ng-repeat=\"model in collection track by model.id\">\n *      {{model.name}}\n *    </div>\n * ```\n *\n * <br />\n * <div class=\"alert alert-warning\">\n * Avoid using `track by $index` when the repeated template contains\n * {@link guide/expression#one-time-binding one-time bindings}. In such cases, the `nth` DOM\n * element will always be matched with the `nth` item of the array, so the bindings on that element\n * will not be updated even when the corresponding item changes, essentially causing the view to get\n * out-of-sync with the underlying data.\n * </div>\n *\n * When no `track by` expression is provided, it is equivalent to tracking by the built-in\n * `$id` function, which tracks items by their identity:\n * ```html\n *    <div ng-repeat=\"obj in collection track by $id(obj)\">\n *      {{obj.prop}}\n *    </div>\n * ```\n *\n * <br />\n * <div class=\"alert alert-warning\">\n * **Note:** `track by` must always be the last expression:\n * </div>\n * ```\n *    <div ng-repeat=\"model in collection | orderBy: 'id' as filtered_result track by model.id\">\n *      {{model.name}}\n *    </div>\n * ```\n *\n *\n * # Special repeat start and end points\n * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending\n * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.\n * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)\n * up to and including the ending HTML tag where **ng-repeat-end** is placed.\n *\n * The example below makes use of this feature:\n * ```html\n *   <header ng-repeat-start=\"item in items\">\n *     Header {{ item }}\n *   </header>\n *   <div class=\"body\">\n *     Body {{ item }}\n *   </div>\n *   <footer ng-repeat-end>\n *     Footer {{ item }}\n *   </footer>\n * ```\n *\n * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:\n * ```html\n *   <header>\n *     Header A\n *   </header>\n *   <div class=\"body\">\n *     Body A\n *   </div>\n *   <footer>\n *     Footer A\n *   </footer>\n *   <header>\n *     Header B\n *   </header>\n *   <div class=\"body\">\n *     Body B\n *   </div>\n *   <footer>\n *     Footer B\n *   </footer>\n * ```\n *\n * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such\n * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).\n *\n * @animations\n * | Animation                        | Occurs                              |\n * |----------------------------------|-------------------------------------|\n * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |\n * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |\n * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |\n *\n * See the example below for defining CSS animations with ngRepeat.\n *\n * @element ANY\n * @scope\n * @priority 1000\n * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These\n *   formats are currently supported:\n *\n *   * `variable in expression` – where variable is the user defined loop variable and `expression`\n *     is a scope expression giving the collection to enumerate.\n *\n *     For example: `album in artist.albums`.\n *\n *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,\n *     and `expression` is the scope expression giving the collection to enumerate.\n *\n *     For example: `(name, age) in {'adam':10, 'amalie':12}`.\n *\n *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression\n *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression\n *     is specified, ng-repeat associates elements by identity. It is an error to have\n *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are\n *     mapped to the same DOM element, which is not possible.)\n *\n *     Note that the tracking expression must come last, after any filters, and the alias expression.\n *\n *     For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements\n *     will be associated by item identity in the array.\n *\n *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique\n *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements\n *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM\n *     element in the same way in the DOM.\n *\n *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this\n *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`\n *     property is same.\n *\n *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter\n *     to items in conjunction with a tracking expression.\n *\n *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the\n *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message\n *     when a filter is active on the repeater, but the filtered result set is empty.\n *\n *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after\n *     the items have been processed through the filter.\n *\n *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end\n *     (and not as operator, inside an expression).\n *\n *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .\n *\n * @example\n * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed\n * results by name or by age.

The element is shown or hidden by removing or adding\n * the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined\n * in AngularJS and sets the display style to none (using an !important flag).\n * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).\n *\n * ```html\n * <!-- when $scope.myValue is truthy (element is visible) -->\n * <div ng-show=\"myValue\"></div>\n *\n * <!-- when $scope.myValue is falsy (element is hidden) -->\n * <div ng-show=\"myValue\" class=\"ng-hide\"></div>\n * ```\n *\n * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added to the class\n * attribute on the element causing it to become hidden. When truthy, the `.ng-hide` CSS class is removed\n * from the element causing the element not to appear hidden.\n *\n * ## Why is !important used?\n *\n * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector\n * can be easily overridden by heavier selectors. For example, something as simple\n * as changing the display style on a HTML list item would make hidden elements appear visible.\n * This also becomes a bigger issue when dealing with CSS frameworks.\n *\n * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector\n * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the\n * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.\n *\n * ### Overriding `.ng-hide`\n *\n * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change\n * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`\n * class CSS. Note that the selector that needs to be used is actually `.ng-hide:not(.ng-hide-animate)` to cope\n * with extra animation classes that can be added.\n *\n * ```css\n * .ng-hide:not(.ng-hide-animate) {\n *   /&#42; this is just another form of hiding an element &#42;/\n *   display: block!important;\n *   position: absolute;\n *   top: -9999px;\n *   left: -9999px;\n * }\n * ```\n *\n * By default you don't need to override in CSS anything and the animations will work around the display style.\n *\n * ## A note about animations with `ngShow`\n *\n * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression\n * is true and false. This system works like the animation system present with ngClass except that\n * you must also include the !important flag to override the display property\n * so that you can perform an animation when the element is hidden during the time of the animation.\n *\n * ```css\n * //\n * //a working example can be found at the bottom of this page\n * //\n * .my-element.ng-hide-add, .my-element.ng-hide-remove {\n *   /&#42; this is required as of 1.3x to properly\n *      apply all styling in a show/hide animation &#42;/\n *   transition: 0s linear all;\n * }\n *\n * .my-element.ng-hide-add-active,\n * .my-element.ng-hide-remove-active {\n *   /&#42; the transition is defined in the active class &#42;/\n *   transition: 1s linear all;\n * }\n *\n * .my-element.ng-hide-add { ... }\n * .my-element.ng-hide-add.ng-hide-add-active { ... }\n * .my-element.ng-hide-remove { ... }\n * .my-element.ng-hide-remove.ng-hide-remove-active { ... }\n * ```\n *\n * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display\n * property to block during animation states--ngAnimate will handle the style toggling automatically for you.\n *\n * @animations\n * | Animation                        | Occurs                              |\n * |----------------------------------|-------------------------------------|\n * | {@link $animate#addClass addClass} `.ng-hide`  | after the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden |\n * | {@link $animate#removeClass removeClass}  `.ng-hide`  | after the `ngShow` expression evaluates to a truthy value and just before contents are set to visible |\n *\n * @element ANY\n * @param {expression} ngShow If the {@link guide/expression expression} is truthy\n *     then the element is shown or hidden respectively.\n *\n * @example\n  <example module=\"ngAnimate\" deps=\"angular-animate.js\" animations=\"true\" name=\"ng-show\">\n    <file name=\"index.html\">\n      Click me: <input type=\"checkbox\" ng-model=\"checked\" aria-label=\"Toggle ngHide\"><br/>\n      <div>\n        Show:\n        <div class=\"check-element animate-show\" ng-show=\"checked\">\n          <span class=\"glyphicon glyphicon-thumbs-up\"></span> I show up when your checkbox is checked.\n        </div>\n      </div>\n      <div>\n        Hide:\n        <div class=\"check-element animate-show\" ng-hide=\"checked\">\n          <span class=\"glyphicon glyphicon-thumbs-down\"></span> I hide when your checkbox is checked.\n        </div>\n      </div>\n    </file>\n    <file name=\"glyphicons.css\">\n      @import url(../../components/bootstrap-3.1.1/css/bootstrap.css);\n    </file>\n    <file name=\"animations.css\">\n      .animate-show {\n        line-height: 20px;\n        opacity: 1;\n        padding: 10px;\n        border: 1px solid black;\n        background: white;\n      }\n\n      .animate-show.ng-hide-add, .animate-show.ng-hide-remove {\n        transition: all linear 0.5s;\n      }\n\n      .animate-show.ng-hide {\n        line-height: 0;\n        opacity: 0;\n        padding: 0 10px;\n      }\n\n      .check-element {\n        padding: 10px;\n        border: 1px solid black;\n        background: white;\n      }\n    </file>\n    <file name=\"protractor.js\" type=\"protractor\">\n      var thumbsUp = element(by.css('span.glyphicon-thumbs-up'));\n      var thumbsDown = element(by.css('span.glyphicon-thumbs-down'));\n\n      it('should check ng-show / ng-hide', function() {\n        expect(thumbsUp.isDisplayed()).toBeFalsy();\n        expect(thumbsDown.isDisplayed()).toBeTruthy();\n\n        element(by.model('checked')).click();\n\n        expect(thumbsUp.isDisplayed()).toBeTruthy();\n        expect(thumbsDown.isDisplayed()).toBeFalsy();\n      });\n    </file>\n  </example>\n */\nvar ngShowDirective = ['$animate', function($animate) {\n  return {\n    restrict: 'A',\n    multiElement: true,\n    link: function(scope, element, attr) {\n      scope.$watch(attr.ngShow, function ngShowWatchAction(value) {\n        // we're adding a temporary, animation-specific class for ng-hide since this way\n        // we can control when the element is actually displayed on screen without having\n        // to have a global/greedy CSS selector that breaks when other animations are run.\n        // Read: https://github.com/angular/angular.js/issues/9103#issuecomment-58335845\n        $animate[value ?

The element is shown or hidden by removing or adding\n * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined\n * in AngularJS and sets the display style to none (using an !important flag).\n * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).\n *\n * ```html\n * <!-- when $scope.myValue is truthy (element is hidden) -->\n * <div ng-hide=\"myValue\" class=\"ng-hide\"></div>\n *\n * <!-- when $scope.myValue is falsy (element is visible) -->\n * <div ng-hide=\"myValue\"></div>\n * ```\n *\n * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added to the class\n * attribute on the element causing it to become hidden. When falsy, the `.ng-hide` CSS class is removed\n * from the element causing the element not to appear hidden.\n *\n * ## Why is !important used?\n *\n * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector\n * can be easily overridden by heavier selectors. For example, something as simple\n * as changing the display style on a HTML list item would make hidden elements appear visible.\n * This also becomes a bigger issue when dealing with CSS frameworks.\n *\n * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector\n * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the\n * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.\n *\n * ### Overriding `.ng-hide`\n *\n * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change\n * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`\n * class in CSS:\n *\n * ```css\n * .ng-hide {\n *   /&#42; this is just another form of hiding an element &#42;/\n *   display: block!important;\n *   position: absolute;\n *   top: -9999px;\n *   left: -9999px;\n * }\n * ```\n *\n * By default you don't need to override in CSS anything and the animations will work around the display style.\n *\n * ## A note about animations with `ngHide`\n *\n * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression\n * is true and false. This system works like the animation system present with ngClass, except that the `.ng-hide`\n * CSS class is added and removed for you instead of your own CSS class.\n *\n * ```css\n * //\n * //a working example can be found at the bottom of this page\n * //\n * .my-element.ng-hide-add, .my-element.ng-hide-remove {\n *   transition: 0.5s linear all;\n * }\n *\n * .my-element.ng-hide-add { ... }\n * .my-element.ng-hide-add.ng-hide-add-active { ... }\n * .my-element.ng-hide-remove { ... }\n * .my-element.ng-hide-remove.ng-hide-remove-active { ... }\n * ```\n *\n * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display\n * property to block during animation states--ngAnimate will handle the style toggling automatically for you.\n *\n * @animations\n * | Animation                        | Occurs                              |\n * |----------------------------------|-------------------------------------|\n * | {@link $animate#addClass addClass} `.ng-hide`  | after the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden |\n * | {@link $animate#removeClass removeClass}  `.ng-hide`  | after the `ngHide` expression evaluates to a non truthy value and just before contents are set to visible |\n *\n *\n * @element ANY\n * @param {expression} ngHide If the {@link guide/expression expression} is truthy then\n *     the element is shown or hidden respectively.\n *\n * @example\n  <example module=\"ngAnimate\" deps=\"angular-animate.js\" animations=\"true\" name=\"ng-hide\">\n    <file name=\"index.html\">\n      Click me: <input type=\"checkbox\" ng-model=\"checked\" aria-label=\"Toggle ngShow\"><br/>\n      <div>\n        Show:\n        <div class=\"check-element animate-hide\" ng-show=\"checked\">\n          <span class=\"glyphicon glyphicon-thumbs-up\"></span> I show up when your checkbox is checked.\n        </div>\n      </div>\n      <div>\n        Hide:\n        <div class=\"check-element animate-hide\" ng-hide=\"checked\">\n          <span class=\"glyphicon glyphicon-thumbs-down\"></span> I hide when your checkbox is checked.\n        </div>\n      </div>\n    </file>\n    <file name=\"glyphicons.css\">\n      @import url(../../components/bootstrap-3.1.1/css/bootstrap.css);\n    </file>\n    <file name=\"animations.css\">\n      .animate-hide {\n        transition: all linear 0.5s;\n        line-height: 20px;\n        opacity: 1;\n        padding: 10px;\n        border: 1px solid black;\n        background: white;\n      }\n\n      .animate-hide.ng-hide {\n        line-height: 0;\n        opacity: 0;\n        padding: 0 10px;\n      }\n\n      .check-element {\n        padding: 10px;\n        border: 1px solid black;\n        background: white;\n      }\n    </file>\n    <file name=\"protractor.js\" type=\"protractor\">\n      var thumbsUp = element(by.css('span.glyphicon-thumbs-up'));\n      var thumbsDown = element(by.css('span.glyphicon-thumbs-down'));\n\n      it('should check ng-show / ng-hide', function() {\n        expect(thumbsUp.isDisplayed()).toBeFalsy();\n        expect(thumbsDown.isDisplayed()).toBeTruthy();\n\n        element(by.model('checked')).click();\n\n        expect(thumbsUp.isDisplayed()).toBeTruthy();\n        expect(thumbsDown.isDisplayed()).toBeFalsy();\n      });\n    </file>\n  </example>\n */\nvar ngHideDirective = ['$animate', function($animate) {\n  return {\n    restrict: 'A',\n    multiElement: true,\n    link: function(scope, element, attr) {\n      scope.$watch(attr.ngHide, function ngHideWatchAction(value) {\n        // The comment inside of the ngShowDirective explains why we add and\n        // remove a temporary class for the show/hide animation\n        $animate[value ?

With static or repeated options, this is\n * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.\n * Value and textContent can be interpolated.\n *\n * ## Matching model and option values\n *\n * In general, the match between the model and an option is evaluated by strictly comparing the model\n * value against the value of the available options.\n *\n * If you are setting the option value with the option's `value` attribute, or textContent, the\n * value will always be a `string` which means that the model value must also be a string.\n * Otherwise the `select` directive cannot match them correctly.\n *\n * To bind the model to a non-string value, you can use one of the following strategies:\n * - the {@link ng.ngOptions `ngOptions`} directive\n *   ({@link ng.select#using-select-with-ngoptions-and-setting-a-default-value})\n * - the {@link ng.ngValue `ngValue`} directive, which allows arbitrary expressions to be\n *   option values ({@link ng.select#using-ngvalue-to-bind-the-model-to-an-array-of-objects Example})\n * - model $parsers / $formatters to convert the string value\n *   ({@link ng.select#binding-select-to-a-non-string-value-via-ngmodel-parsing-formatting Example})\n *\n * If the viewValue of `ngModel` does not match any of the options, then the control\n * will automatically add an \"unknown\" option, which it then removes when the mismatch is resolved.\n *\n * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can\n * be nested into the `<select>` element. This element will then represent the `null` or \"not selected\"\n * option. See example below for demonstration.\n *\n * ## Choosing between `ngRepeat` and `ngOptions`\n *\n * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions\n * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits:\n * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the\n * comprehension expression\n * - reduced memory consumption by not creating a new scope for each repeated instance\n * - increased render speed by creating the options in a documentFragment instead of individually\n *\n * Specifically, select with repeated options slows down significantly starting at 2000 options in\n * Chrome and Internet Explorer / Edge.\n *\n *\n * @param {string} ngModel Assignable angular expression to data-bind to.\n * @param {string=} name Property name of the form under which the control is published.\n * @param {string=} multiple Allows multiple options to be selected. The selected values will be\n *     bound to the model as an array.\n * @param {string=} required Sets `required` validation error key if the value is not entered.\n * @param {string=} ngRequired Adds required attribute and required validation constraint to\n * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required\n * when you want to data-bind to the required attribute.\n * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user\n *    interaction with the select element.\n * @param {string=} ngOptions sets the options that the select is populated with and defines what is\n * set on the model on selection. See {@link ngOptions `ngOptions`}.\n *\n * @example\n * ### Simple `select` elements with static options\n *\n * <example name=\"static-select\" module=\"staticSelect\">\n * <file

required {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.\n * It is most often used for {@link input `input`} and {@link select `select`} controls, but can also be\n * applied to custom controls.\n *\n * The directive sets the `required` attribute on the element if the Angular expression inside\n * `ngRequired` evaluates to true. A special directive for setting `required` is necessary because we\n * cannot use interpolation inside `required`. See the {@link guide/interpolation interpolation guide}\n * for more info.\n *\n * The validator will set the `required` error key to true if the `required` attribute is set and\n * calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the\n * {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the\n * `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing\n * custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.\n *\n * @example\n * <example name=\"ngRequiredDirective\" module=\"ngRequiredExample\">\n *   <file name=\"index.html\">\n *     <script>\n *       angular.module('ngRequiredExample', [])\n *         .controller('ExampleController', ['$scope', function($scope) {\n *           $scope.required = true;\n *         }]);\n *     </script>\n *     <div ng-controller=\"ExampleController\">\n *       <form name=\"form\">\n *         <label for=\"required\">Toggle required: </label>\n *         <input type=\"checkbox\" ng-model=\"required\" id=\"required\" />\n *         <br>\n *         <label for=\"input\">This input must be filled if `required` is true: </label>\n *         <input type=\"text\" ng-model=\"model\" id=\"input\" name=\"input\" ng-required=\"required\" /><br>\n *         <hr>\n *         required error set? = <code>{{form.input.$error.required}}</code><br>\n *         model = <code>{{model}}</code>\n *       </form>\n *     </div>\n *   </file>\n *   <file name=\"protractor.js\" type=\"protractor\">\n       var required = element(by.binding('form.input.$error.required'));\n       var model = element(by.binding('model'));\n       var input = element(by.id('input'));\n\n       it('should set the required error', function() {\n         expect(required.getText()).toContain('true');\n\n         input.sendKeys('123');\n         expect(required.getText()).not.toContain('true');\n         expect(model.getText()).toContain('123');\n       });\n *   </file>\n * </example>\n */\nvar requiredDirective = function() {\n  return {\n    restrict: 'A',\n    require: '?ngModel',\n    link: function(scope, elm, attr, ctrl) {\n      if (!ctrl) return;\n      attr.required = true; // force truthy in case we are on non input element\n\n      ctrl.$validators.required = function(modelValue, viewValue) {\n        return !attr.required || !ctrl.$isEmpty(viewValue);\n      };\n\n      attr.$observe('required', function() {\n        ctrl.$validate();\n      });\n    }\n  };\n};\n\n/**\n * @ngdoc directive\n * @name ngPattern\n *\n * @description\n *\n * ngPattern adds the pattern {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.\n * It is most often used for text-based {@link input `input`} controls, but can also be applied to custom text-based controls.\n *\n * The validator sets the `pattern` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}\n * does not match a RegExp which is obtained by evaluating the Angular expression given in the\n * `ngPattern` attribute value:\n * * If the expression evaluates to a RegExp object, then this is used directly.\n * * If the expression evaluates to a string, then it will be converted to a RegExp after wrapping it\n * in `^` and `$` characters.

When you are ready for your app to be initialized, call its\n    `advanceReadiness()` method.\n  \n    You can define a `ready` method on the `Ember.Application` instance, which\n    will be run by Ember when the application is initialized.\n  \n    Because `Ember.Application` inherits from `Ember.Namespace`, any classes\n    you create will have useful string representations when calling `toString()`.\n    See the `Ember.Namespace` documentation for more information.\n  \n    While you can think of your `Ember.Application` as a container that holds the\n    other classes in your application, there are several other responsibilities\n    going on under-the-hood that you may want to understand.\n  \n    ### Event Delegation\n  \n    Ember uses a technique called _event delegation_. This allows the framework\n    to set up a global, shared event listener instead of requiring each view to\n    do it manually. For example, instead of each view registering its own\n    `mousedown` listener on its associated element, Ember sets up a `mousedown`\n    listener on the `body`.\n  \n    If a `mousedown` event occurs, Ember will look at the target of the event and\n    start walking up the DOM node tree, finding corresponding views and invoking\n    their `mouseDown` method as it goes.\n  \n    `Ember.Application` has a number of default events that it listens for, as\n    well as a mapping from lowercase events to camel-cased view method names. For\n    example, the `keypress` event causes the `keyPress` method on the view to be\n    called, the `dblclick` event causes `doubleClick` to be called, and so on.\n  \n    If there is a bubbling browser event that Ember does not listen for by\n    default, you can specify custom events and their corresponding view method\n    names by setting the application's `customEvents` property:\n  \n    ```javascript\n    let App = Ember.Application.create({\n      customEvents: {\n        // add support for the paste event\n        paste: 'paste'\n      }\n    });\n    ```\n  \n    To prevent Ember from setting up a listener for a default event,\n    specify the event name with a `null` value in the `customEvents`\n    property:\n  \n    ```javascript\n    let App = Ember.Application.create({\n      customEvents: {\n        // prevent listeners for mouseenter/mouseleave events\n        mouseenter: null,\n        mouseleave: null\n      }\n    });\n    ```\n  \n    By default, the application sets up these event listeners on the document\n    body. However, in cases where you are embedding an Ember application inside\n    an existing page, you may want it to set up the listeners on an element\n    inside the body.\n  \n    For example, if only events inside a DOM element with the ID of `ember-app`\n    should be delegated, set your application's `rootElement` property:\n  \n    ```javascript\n    let App = Ember.Application.create({\n      rootElement: '#ember-app'\n    });\n    ```\n  \n    The `rootElement` can be either a DOM element or a jQuery-compatible selector\n    string. Note that *views appended to the DOM outside the root element will\n    not receive events.* If you specify a custom root element, make sure you only\n    append views inside it!\n  \n    To learn more about the events Ember components use, see\n    [components/handling-events](https://guides.emberjs.com/v2.6.0/components/handling-events/#toc_event-names).\n  \n    ### Initializers\n  \n    Libraries on top of Ember can add initializers, like so:\n  \n    ```javascript\n    Ember.Application.initializer({\n      name: 'api-adapter',\n  \n      initialize: function(application) {\n        application.register('api-adapter:main', ApiAdapter);\n      }\n    });\n    ```\n  \n    Initializers provide an opportunity to access the internal registry, which\n    organizes the different components of an Ember application. Additionally\n    they provide a chance to access the instantiated application. Beyond\n    being used for libraries, initializers are also a great way to organize\n    dependency injection or setup in your own application.\n  \n    ### Routing\n  \n    In addition to creating your application's router, `Ember.Application` is\n    also responsible for telling the router when to start routing. Transitions\n    between routes can be logged with the `LOG_TRANSITIONS` flag, and more\n    detailed intra-transition logging can be logged with\n    the `LOG_TRANSITIONS_INTERNAL` flag:\n  \n    ```javascript\n    let App = Ember.Application.create({\n      LOG_TRANSITIONS: true, // basic logging of successful transitions\n      LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps\n    });\n    ```\n  \n    By default, the router will begin trying to translate the current URL into\n    application state once the browser emits the `DOMContentReady` event. If you\n    need to defer routing, you can call the application's `deferReadiness()`\n    method. Once routing can begin, call the `advanceReadiness()` method.\n  \n    If there is any setup required before routing begins, you can implement a\n    `ready()` method on your app that will be invoked immediately before routing\n    begins.\n  \n    @class Application\n    @namespace Ember\n    @extends Ember.Engine\n    @uses RegistryProxyMixin\n    @public\n  */\n\n  var Application = _emberApplicationSystemEngine.default.extend({\n    /**\n      The root DOM element of the Application. This can be specified as an\n      element or a\n      [jQuery-compatible selector string](http://api.jquery.com/category/selectors/).\n       This is the element that will be passed to the Application's,\n      `eventDispatcher`, which sets up the listeners for event delegation.

See the documentation on\n      `Ember.ApplicationInstance.BootOptions` for details.\n       `Ember.ApplicationInstance.BootOptions` is an interface class that exists\n      purely to document the available options; you do not need to construct it\n      manually. Simply pass a regular JavaScript object containing of the\n      desired options:\n       ```javascript\n      MyApp.visit(\"/\", { location: \"none\", rootElement: \"#container\" });\n      ```\n       ### Supported Scenarios\n       While the `BootOptions` class exposes a large number of knobs, not all\n      combinations of them are valid; certain incompatible combinations might\n      result in unexpected behavior.\n       For example, booting the instance in the full browser environment\n      while specifying a foriegn `document` object (e.g. `{ isBrowser: true,\n      document: iframe.contentDocument }`) does not work correctly today,\n      largely due to Ember's jQuery dependency.\n       Currently, there are three officially supported scenarios/configurations.\n      Usages outside of these scenarios are not guaranteed to work, but please\n      feel free to file bug reports documenting your experience and any issues\n      you encountered to help expand support.\n       #### Browser Applications (Manual Boot)\n       The setup is largely similar to how Ember works out-of-the-box. Normally,\n      Ember will boot a default instance for your Application on \"DOM ready\".\n      However, you can customize this behavior by disabling `autoboot`.\n       For example, this allows you to render a miniture demo of your application\n      into a specific area on your marketing website:\n       ```javascript\n      import MyApp from 'my-app';\n       $(function() {\n        let App = MyApp.create({ autoboot: false });\n         let options = {\n          // Override the router's location adapter to prevent it from updating\n          // the URL in the address bar\n          location: 'none',\n           // Override the default `rootElement` on the app to render into a\n          // specific `div` on the page\n          rootElement: '#demo'\n        };\n         // Start the app at the special demo URL\n        App.visit('/demo', options);\n      });\n      ````\n       Or perhaps you might want to boot two instances of your app on the same\n      page for a split-screen multiplayer experience:\n       ```javascript\n      import MyApp from 'my-app';\n       $(function() {\n        let App = MyApp.create({ autoboot: false });\n         let sessionId = MyApp.generateSessionID();\n         let player1 = App.visit(`/matches/join?name=Player+1&session=${sessionId}`, { rootElement: '#left', location: 'none' });\n        let player2 = App.visit(`/matches/join?name=Player+2&session=${sessionId}`, { rootElement: '#right', location: 'none' });\n         Promise.all([player1, player2]).then(() => {\n          // Both apps have completed the initial render\n          $('#loading').fadeOut();\n        });\n      });\n      ```\n       Do note that each app instance maintains their own registry/container, so\n      they will run in complete isolation by default.\n       #### Server-Side Rendering (also known as FastBoot)\n       This setup allows you to run your Ember app in a server environment using\n      Node.js and render its content into static HTML for SEO purposes.\n       ```javascript\n      const HTMLSerializer = new SimpleDOM.HTMLSerializer(SimpleDOM.voidMap);\n       function renderURL(url) {\n        let dom = new SimpleDOM.Document();\n        let rootElement = dom.body;\n        let options = { isBrowser: false, document: dom, rootElement: rootElement };\n         return MyApp.visit(options).then(instance => {\n          try {\n            return HTMLSerializer.serialize(rootElement.firstChild);\n          } finally {\n            instance.destroy();\n          }\n        });\n      }\n      ```\n       In this scenario, because Ember does not have access to a global `document`\n      object in the Node.js environment, you must provide one explicitly. In practice,\n      in the non-browser environment, the stand-in `document` object only need to\n      implement a limited subset of the full DOM API. The `SimpleDOM` library is known\n      to work.\n       Since there is no access to jQuery in the non-browser environment, you must also\n      specify a DOM `Element` object in the same `document` for the `rootElement` option\n      (as opposed to a selector string like `\"body\"`).\n       See the documentation on the `isBrowser`, `document` and `rootElement` properties\n      on `Ember.ApplicationInstance.BootOptions` for details.\n       #### Server-Side Resource Discovery\n       This setup allows you to run the routing layer of your Ember app in a server\n      environment using Node.js and completely disable rendering. This allows you\n      to simulate and discover the resources (i.e. AJAX requests) needed to fufill\n      a given request and eagerly \"push\" these resources to the client.\n       ```app/initializers/network-service.js\n      import BrowserNetworkService from 'app/services/network/browser';\n      import NodeNetworkService from 'app/services/network/node';\n       // Inject a (hypothetical) service for abstracting all AJAX calls and use\n      // the appropiate implementaion on the client/server. This also allows the\n      // server to log all the AJAX calls made during a particular request and use\n      // that for resource-discovery purpose.\n       export function initialize(application) {\n        if (window) { // browser\n          application.register('service:network', BrowserNetworkService);\n        } else { // node\n          application.register('service:network', NodeNetworkService);\n        }\n         application.inject('route', 'network', 'service:network');\n      };\n       export default {\n        name: 'network-service',\n        initialize: initialize\n      };\n      ```\n       ```app/routes/post.js\n      import Ember from 'ember';\n       // An example of how the (hypothetical) service is used in routes.\n       export default Ember.Route.extend({\n        model(params) {\n          return this.network.fetch(`/api/posts/${params.post_id}.json`);\n        },\n         afterModel(post) {\n          if (post.isExternalContent) {\n            return this.network.fetch(`/api/external/?url=${post.externalURL}`);\n          } else {\n            return post;\n          }\n        }\n      });\n      ```\n       ```javascript\n      // Finally, put all the pieces together\n       function discoverResourcesFor(url) {\n        return MyApp.visit(url, { isBrowser: false, shouldRender: false }).then(instance => {\n          let networkService = instance.lookup('service:network');\n          return networkService.requests; // => { \"/api/posts/123.json\": \"...\" }\n        });\n      }\n      ```\n       @public\n      @method visit\n      @param url {String} The initial URL to navigate to\n      @param options {Ember.ApplicationInstance.BootOptions}\n      @return {Promise<Ember.ApplicationInstance, Error>}\n    */\n    visit: function (url, options) {\n      var _this = this;\n\n      return this.boot().then(function () {\n        var instance = _this.buildInstance();\n\n        return instance.boot(options).then(function () {\n          return instance.visit(url);\n        }).catch(function (error) {\n          _emberMetal.run(instance, 'destroy');\n          throw error;\n        });\n      });\n    }\n  });\n\n  Object.defineProperty(Application.prototype, 'registry', {\n    configurable: true,\n    enumerable: false,\n    get: function () {\n      return _emberRuntime.buildFakeRegistryWithDeprecations(this, 'Application');\n    }\n  });\n\n  Application.reopenClass({\n    /**\n      This creates a registry with the default Ember naming conventions.\n       It also configures the registry:\n       * registered views are created every time they are looked up (they are\n        not singletons)\n      * registered templates are not factories;

For example, you could enhance how a template\n    is resolved like so:\n  \n    ```javascript\n    App = Ember.Application.create({\n      Resolver: Ember.DefaultResolver.extend({\n        resolveTemplate: function(parsedName) {\n          let resolvedTemplate = this._super(parsedName);\n          if (resolvedTemplate) { return resolvedTemplate; }\n          return Ember.TEMPLATES['not_found'];\n        }\n      })\n    });\n    ```\n  \n    Some examples of how names are resolved:\n  \n    ```\n    'template:post'           //=> Ember.TEMPLATES['post']\n    'template:posts/byline'   //=> Ember.TEMPLATES['posts/byline']\n    'template:posts.byline'   //=> Ember.TEMPLATES['posts/byline']\n    'template:blogPost'       //=> Ember.TEMPLATES['blogPost']\n                              //   OR\n                              //   Ember.TEMPLATES['blog_post']\n    'controller:post'         //=> App.PostController\n    'controller:posts.index'  //=> App.PostsIndexController\n    'controller:blog/post'    //=> Blog.PostController\n    'controller:basic'        //=> Ember.Controller\n    'route:post'              //=> App.PostRoute\n    'route:posts.index'       //=> App.PostsIndexRoute\n    'route:blog/post'         //=> Blog.PostRoute\n    'route:basic'             //=> Ember.Route\n    'view:post'               //=> App.PostView\n    'view:posts.index'        //=> App.PostsIndexView\n    'view:blog/post'          //=> Blog.PostView\n    'view:basic'              //=> Ember.View\n    'foo:post'                //=> App.PostFoo\n    'model:post'              //=> App.Post\n    ```\n  \n    @class DefaultResolver\n    @namespace Ember\n    @extends Ember.Object\n    @public\n  */\n\n  exports.default = _emberRuntime.Object.extend({\n    /**\n      This will be set to the Application instance when it is\n      created.\n       @property namespace\n      @public\n    */\n    namespace: null,\n\n    init: function () {\n      this._parseNameCache = _emberUtils.dictionary(null);\n    },\n    normalize: function (fullName) {\n      var _fullName$split = fullName.split(':', 2);\n\n      var type = _fullName$split[0];\n      var name = _fullName$split[1];\n\n      _emberDebug.assert('Tried to normalize a container name without a colon (:) in it.

Properties accessed in its templates go\n    to the view object and actions are targeted at\n    the view object. There is no access to the\n    surrounding context or outer controller; all\n    contextual information must be passed in.\n  \n    The easiest way to create an `Ember.Component` is via\n    a template. If you name a template\n    `app/components/my-foo.hbs`, you will be able to use\n    `{{my-foo}}` in other templates, which will make\n    an instance of the isolated component.\n  \n    ```app/components/my-foo.hbs\n    {{person-profile person=currentUser}}\n    ```\n  \n    ```app/components/person-profile.hbs\n    <h1>{{person.title}}</h1>\n    <img src={{person.avatar}}>\n    <p class='signature'>{{person.signature}}</p>\n    ```\n  \n    You can use `yield` inside a template to\n    include the **contents** of any block attached to\n    the component. The block will be executed in the\n    context of the surrounding context or outer controller:\n  \n    ```handlebars\n    {{#person-profile person=currentUser}}\n      <p>Admin mode</p>\n      {{! Executed in the controller's context. }}\n    {{/person-profile}}\n    ```\n  \n    ```app/components/person-profile.hbs\n    <h1>{{person.title}}</h1>\n    {{! Executed in the component's context. }}\n    {{yield}} {{! block contents }}\n    ```\n  \n    If you want to customize the component, in order to\n    handle events or actions, you implement a subclass\n    of `Ember.Component` named after the name of the\n    component.\n  \n    For example, you could implement the action\n    `hello` for the `person-profile` component:\n  \n    ```app/components/person-profile.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      actions: {\n        hello(name) {\n          console.log(\"Hello\", name);\n        }\n      }\n    });\n    ```\n  \n    And then use it in the component's template:\n  \n    ```app/templates/components/person-profile.hbs\n    <h1>{{person.title}}</h1>\n    {{yield}} <!-- block contents -->\n    <button {{action 'hello' person.name}}>\n      Say Hello to {{person.name}}\n    </button>\n    ```\n  \n    Components must have a `-` in their name to avoid\n    conflicts with built-in controls that wrap HTML\n    elements. This is consistent with the same\n    requirement in web components.\n  \n  \n    ## HTML Tag\n  \n    The default HTML tag name used for a component's DOM representation is `div`.\n    This can be customized by setting the `tagName` property.\n    The following component class:\n  \n    ```app/components/emphasized-paragraph.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      tagName: 'em'\n    });\n    ```\n  \n    Would result in instances with the following HTML:\n  \n    ```html\n    <em id=\"ember1\" class=\"ember-view\"></em>\n    ```\n  \n  \n    ## HTML `class` Attribute\n  \n    The HTML `class` attribute of a component's tag can be set by providing a\n    `classNames` property that is set to an array of strings:\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      classNames: ['my-class', 'my-other-class']\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view my-class my-other-class\"></div>\n    ```\n  \n    `class` attribute values can also be set by providing a `classNameBindings`\n    property set to an array of properties names for the component. The return value\n    of these properties will be added as part of the value for the components's `class`\n    attribute. These properties can be computed properties:\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      classNameBindings: ['propertyA', 'propertyB'],\n      propertyA: 'from-a',\n      propertyB: Ember.computed(function() {\n        if (someLogic) { return 'from-b'; }\n      })\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view from-a from-b\"></div>\n    ```\n  \n    If the value of a class name binding returns a boolean the property name\n    itself will be used as the class name if the property is true.\n    The class name will not be added if the value is `false` or `undefined`.\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      classNameBindings: ['hovered'],\n      hovered: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view hovered\"></div>\n    ```\n  \n    When using boolean class name bindings you can supply a string value other\n    than the property name for use as the `class` HTML attribute by appending the\n    preferred value after a \":\" character when defining the binding:\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      classNameBindings: ['awesome:so-very-cool'],\n      awesome: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view so-very-cool\"></div>\n    ```\n  \n    Boolean value class name bindings whose property names are in a\n    camelCase-style format will be converted to a dasherized format:\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      classNameBindings: ['isUrgent'],\n      isUrgent: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view is-urgent\"></div>\n    ```\n  \n    Class name bindings can also refer to object values that are found by\n    traversing a path relative to the component itself:\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      classNameBindings: ['messages.empty'],\n      messages: Ember.Object.create({\n        empty: true\n      })\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view empty\"></div>\n    ```\n  \n    If you want to add a class name for a property which evaluates to true and\n    and a different class name if it evaluates to false, you can pass a binding\n    like this:\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      classNameBindings: ['isEnabled:enabled:disabled'],\n      isEnabled: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view enabled\"></div>\n    ```\n  \n    When isEnabled is `false`, the resulting HTML representation looks like\n    this:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view disabled\"></div>\n    ```\n  \n    This syntax offers the convenience to add a class if a property is `false`:\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false\n    export default Ember.Component.extend({\n      classNameBindings: ['isEnabled::disabled'],\n      isEnabled: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view\"></div>\n    ```\n  \n    When the `isEnabled` property on the component is set to `false`, it will result\n    in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view disabled\"></div>\n    ```\n  \n    Updates to the value of a class name binding will result in automatic\n    update of the  HTML `class` attribute in the component's rendered HTML\n    representation. If the value becomes `false` or `undefined` the class name\n    will be removed.\n    Both `classNames` and `classNameBindings` are concatenated properties. See\n    [Ember.Object](/api/classes/Ember.Object.html) documentation for more\n    information about concatenated properties.\n  \n  \n    ## HTML Attributes\n  \n    The HTML attribute section of a component's tag can be set by providing an\n    `attributeBindings` property set to an array of property names on the component.\n    The return value of these properties will be used as the value of the component's\n    HTML associated attribute:\n  \n    ```app/components/my-anchor.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      tagName: 'a',\n      attributeBindings: ['href'],\n      href: 'http://google.com'\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <a id=\"ember1\" class=\"ember-view\" href=\"http://google.com\"></a>\n    ```\n  \n    One property can be mapped on to another by placing a \":\" between\n    the source property and the destination property:\n  \n    ```app/components/my-anchor.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      tagName: 'a',\n      attributeBindings: ['url:href'],\n      url: 'http://google.com'\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <a id=\"ember1\" class=\"ember-view\" href=\"http://google.com\"></a>\n    ```\n  \n    Namespaced attributes (e.g. `xlink:href`) are supported, but have to be\n    mapped, since `:` is not a valid character for properties in Javascript:\n  \n    ```app/components/my-use.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      tagName: 'use',\n      attributeBindings: ['xlinkHref:xlink:href'],\n      xlinkHref: '#triangle'\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <use xlink:href=\"#triangle\"></use>\n    ```\n  \n    If the return value of an `attributeBindings` monitored property is a boolean\n    the attribute will be present or absent depending on the value:\n  \n    ```app/components/my-text-input.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      tagName: 'input',\n      attributeBindings: ['disabled'],\n      disabled: false\n    });\n    ```\n  \n    Will result in a component instance with an HTML representation of:\n  \n    ```html\n    <input id=\"ember1\" class=\"ember-view\" />\n    ```\n  \n    `attributeBindings` can refer to computed properties:\n  \n    ```app/components/my-text-input.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      tagName: 'input',\n      attributeBindings: ['disabled'],\n      disabled: Ember.computed(function() {\n        if (someLogic) {\n          return true;\n        } else {\n          return false;\n        }\n      })\n    });\n    ```\n  \n    To prevent setting an attribute altogether, use `null` or `undefined` as the\n    return value of the `attributeBindings` monitored property:\n  \n    ```app/components/my-text-input.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      tagName: 'form',\n      attributeBindings: ['novalidate'],\n      novalidate: null\n    });\n    ```\n  \n    Updates to the property of an attribute binding will result in automatic\n    update of the  HTML attribute in the component's rendered HTML representation.\n    `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)\n    documentation for more information about concatenated properties.\n  \n  \n    ## Layouts\n  \n    See [Ember.Templates.helpers.yield](/api/classes/Ember.Templates.helpers.html#method_yield)\n    for more information.\n  \n  \n    ## Responding to Browser Events\n  \n    Components can respond to user-initiated events in one of three ways: method\n    implementation, through an event manager, and through `{{action}}` helper use\n    in their template or layout.\n  \n  \n    ### Method Implementation\n  \n    Components can respond to user-initiated events by implementing a method that\n    matches the event name. A `jQuery.Event` object will be passed as the\n    argument to this method.\n  \n    ```app/components/my-widget.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      click(event) {\n        // will be called when an instance's\n        // rendered element is clicked\n      }\n    });\n    ```\n  \n  \n    ### `{{action}}` Helper\n  \n    See [Ember.Templates.helpers.action](/api/classes/Ember.Templates.helpers.html#method_action).\n  \n  \n    ### Event Names\n  \n    All of the event handling approaches described above respond to the same set\n    of events. The names of the built-in events are listed below. (The hash of\n    built-in events exists in `Ember.EventDispatcher`.) Additional, custom events\n    can be registered by using `Ember.Application.customEvents`.\n  \n    Touch events:\n  \n    * `touchStart`\n    * `touchMove`\n    * `touchEnd`\n    * `touchCancel`\n  \n    Keyboard events:\n  \n    * `keyDown`\n    * `keyUp`\n    * `keyPress`\n  \n    Mouse events:\n  \n    * `mouseDown`\n    * `mouseUp`\n    * `contextMenu`\n    * `click`\n    * `doubleClick`\n    * `mouseMove`\n    * `focusIn`\n    * `focusOut`\n    * `mouseEnter`\n    * `mouseLeave`\n  \n    Form events:\n  \n    * `submit`\n    * `change`\n    * `focusIn`\n    * `focusOut`\n    * `input`\n  \n    HTML5 drag and drop events:\n  \n    * `dragStart`\n    * `drag`\n    * `dragEnter`\n    * `dragLeave`\n    * `dragOver`\n    * `dragEnd`\n    * `drop`\n  \n    @class Component\n    @namespace Ember\n    @extends Ember.CoreView\n    @uses Ember.TargetActionSupport\n    @uses Ember.ClassNamesSupport\n    @uses Ember.ActionSupport\n    @uses Ember.ViewMixin\n    @uses Ember.ViewStateSupport\n    @public\n  */\n  var Component = _emberViews.CoreView.extend(_emberViews.ChildViewsSupport, _emberViews.ViewStateSupport, _emberViews.ClassNamesSupport, _emberRuntime.TargetActionSupport, _emberViews.ActionSupport, _emberViews.ViewMixin, (_CoreView$extend = {\n    isComponent: true,\n\n    init: function () {\n      var _this = this;\n\n      this._super.apply(this, arguments);\n      this[IS_DISPATCHING_ATTRS] = false;\n      this[DIRTY_TAG] = new _glimmerReference.DirtyableTag();\n      this[ROOT_REF] = new _emberGlimmerUtilsReferences.RootReference(this);\n      this[BOUNDS] = null;\n\n      // If a `defaultLayout` was specified move it to the `layout` prop.\n      // `layout` is no longer a CP, so this just ensures that the `defaultLayout`\n      // logic is supported with a deprecation\n      if (this.defaultLayout && !this.layout) {\n        _emberDebug.deprecate('Specifying `defaultLayout` to ' + this + ' is deprecated.

If an attribute has not\n  changed, it is important not to clobber the element's \"hidden state\".\n  For example, if you set an input's `value` to the same value as before,\n  it will clobber selection state and cursor position. In other words,\n  setting an attribute is not **always** idempotent.\n   This method provides a way to read an element's attribute and also\n  update the last value Ember knows about at the same time. This makes\n  setting an attribute idempotent.\n   In particular, what this means is that if you get an `<input>` element's\n  `value` attribute and then re-render the template with the same value,\n  it will avoid clobbering the cursor and selection position.\n  Since most attribute sets are idempotent in the browser, you typically\n  can get away with reading attributes using jQuery, but the most reliable\n  way to do so is through this method.\n  @method readDOMAttr\n   @param {String} name the name of the attribute\n  @return String\n  @public\n */\nenifed('ember-glimmer/components/checkbox', ['exports', 'ember-metal', 'ember-glimmer/component', 'ember-glimmer/templates/empty'], function (exports, _emberMetal, _emberGlimmerComponent, _emberGlimmerTemplatesEmpty) {\n  'use strict';\n\n  /**\n  @module ember\n  @submodule ember-views\n  */\n\n  /**\n    The internal class used to create text inputs when the `{{input}}`\n    helper is used with `type` of `checkbox`.\n  \n    See [Ember.Templates.helpers.input](/api/classes/Ember.Templates.helpers.html#method_input)  for usage details.\n  \n    ## Direct manipulation of `checked`\n  \n    The `checked` attribute of an `Ember.Checkbox` object should always be set\n    through the Ember object or by interacting with its rendered element\n    representation via the mouse, keyboard, or touch.

For example, if the application's\n    current route is 'photoGallery.recent' the following\n    use of `{{link-to}}`:\n  \n    ```handlebars\n    {{#link-to 'photoGallery.recent'}}\n      Great Hamster Photos\n    {{/link-to}}\n    ```\n  \n    will result in\n  \n    ```html\n    <a href=\"/hamster-photos/this-week\" class=\"active\">\n      Great Hamster Photos\n    </a>\n    ```\n  \n    The CSS class name used for active classes can be customized\n    for a single use of `{{link-to}}` by passing an `activeClass`\n    option:\n  \n    ```handlebars\n    {{#link-to 'photoGallery.recent' activeClass=\"current-url\"}}\n      Great Hamster Photos\n    {{/link-to}}\n    ```\n  \n    ```html\n    <a href=\"/hamster-photos/this-week\" class=\"current-url\">\n      Great Hamster Photos\n    </a>\n    ```\n  \n    To override this option for your entire application, see\n    \"Overriding Application-wide Defaults\".\n  \n    ### Keeping a link active for other routes\n  \n    If you need a link to be 'active' even when it doesn't match\n    the current route, you can use the `current-when` argument.\n  \n    ```handlebars\n    {{#link-to 'photoGallery' current-when='photos'}}\n      Photo Gallery\n    {{/link-to}}\n    ```\n  \n    This may be helpful for keeping links active for:\n  \n    * non-nested routes that are logically related\n    * some secondary menu approaches\n    * 'top navigation' with 'sub navigation' scenarios\n  \n    A link will be active if `current-when` is `true` or the current\n    route is the route this link would transition to.\n  \n    To match multiple routes 'space-separate' the routes:\n  \n    ```handlebars\n    {{#link-to 'gallery' current-when='photos drawings paintings'}}\n      Art Gallery\n    {{/link-to}}\n    ```\n  \n    ### Supplying a model\n    An optional model argument can be used for routes whose\n    paths contain dynamic segments. This argument will become\n    the model context of the linked route:\n  \n    ```javascript\n    Router.map(function() {\n      this.route(\"photoGallery\", {path: \"hamster-photos/:photo_id\"});\n    });\n    ```\n  \n    ```handlebars\n    {{#link-to 'photoGallery' aPhoto}}\n      {{aPhoto.title}}\n    {{/link-to}}\n    ```\n  \n    ```html\n    <a href=\"/hamster-photos/42\">\n      Tomster\n    </a>\n    ```\n  \n    ### Supplying multiple models\n    For deep-linking to route paths that contain multiple\n    dynamic segments, multiple model arguments can be used.\n    As the router transitions through the route path, each\n    supplied model argument will become the context for the\n    route with the dynamic segments:\n  \n    ```javascript\n    Router.map(function() {\n      this.route(\"photoGallery\", { path: \"hamster-photos/:photo_id\" }, function() {\n        this.route(\"comment\", {path: \"comments/:comment_id\"});\n      });\n    });\n    ```\n    This argument will become the model context of the linked route:\n  \n    ```handlebars\n    {{#link-to 'photoGallery.comment' aPhoto comment}}\n      {{comment.body}}\n    {{/link-to}}\n    ```\n  \n    ```html\n    <a href=\"/hamster-photos/42/comments/718\">\n      A+++ would snuggle again.\n    </a>\n    ```\n  \n    ### Supplying an explicit dynamic segment value\n    If you don't have a model object available to pass to `{{link-to}}`,\n    an optional string or integer argument can be passed for routes whose\n    paths contain dynamic segments. This argument will become the value\n    of the dynamic segment:\n  \n    ```javascript\n    Router.map(function() {\n      this.route(\"photoGallery\", { path: \"hamster-photos/:photo_id\" });\n    });\n    ```\n  \n    ```handlebars\n    {{#link-to 'photoGallery' aPhotoId}}\n      {{aPhoto.title}}\n    {{/link-to}}\n    ```\n  \n    ```html\n    <a href=\"/hamster-photos/42\">\n      Tomster\n    </a>\n    ```\n  \n    When transitioning into the linked route, the `model` hook will\n    be triggered with parameters including this passed identifier.\n  \n    ### Allowing Default Action\n  \n   By default the `{{link-to}}` component prevents the default browser action\n   by calling `preventDefault()` as this sort of action bubbling is normally\n   handled internally and we do not want to take the browser to a new URL (for\n   example).\n  \n   If you need to override this behavior specify `preventDefault=false` in\n   your template:\n  \n    ```handlebars\n    {{#link-to 'photoGallery' aPhotoId preventDefault=false}}\n      {{aPhotoId.title}}\n    {{/link-to}}\n    ```\n  \n    ### Overriding attributes\n    You can override any given property of the `Ember.LinkComponent`\n    that is generated by the `{{link-to}}` component by passing\n    key/value pairs, like so:\n  \n    ```handlebars\n    {{#link-to  aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}\n      Uh-mazing!\n    {{/link-to}}\n    ```\n  \n    See [Ember.LinkComponent](/api/classes/Ember.LinkComponent.html) for a\n    complete list of overrideable properties.

Type into\n    either text area box and they'll both stay in sync. Note that\n    `Ember.computed.alias` costs more in terms of performance, so only use it when\n    your really binding in both directions:\n  \n    ```javascript\n    App.ApplicationController = Ember.Controller.extend({\n      writtenWords: \"Lots of text that IS bound\",\n      twoWayWrittenWords: Ember.computed.alias(\"writtenWords\")\n    });\n    ```\n  \n    ```handlebars\n    {{textarea value=writtenWords}}\n    {{textarea value=twoWayWrittenWords}}\n    ```\n  \n    ```html\n    <textarea id=\"ember1\" class=\"ember-text-area\">\n      Lots of text that IS bound\n    </textarea>\n    <-- both updated in real time -->\n    <textarea id=\"ember2\" class=\"ember-text-area\">\n      Lots of text that IS bound\n    </textarea>\n    ```\n  \n    ### Actions\n  \n    The helper can send multiple actions based on user events.\n    The action property defines the action which is send when\n    the user presses the return key.\n  \n    ```handlebars\n    {{input action=\"submit\"}}\n    ```\n  \n    The helper allows some user events to send actions.\n  \n    * `enter`\n    * `insert-newline`\n    * `escape-press`\n    * `focus-in`\n    * `focus-out`\n    * `key-press`\n  \n    For example, if you desire an action to be sent when the input is blurred,\n    you only need to setup the action name to the event name property.\n  \n    ```handlebars\n    {{textarea focus-out=\"alertMessage\"}}\n    ```\n  \n    See more about [Text Support Actions](/api/classes/Ember.TextArea.html)\n  \n    ### Extension\n  \n    Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing\n    arguments from the helper to `Ember.TextArea`'s `create` method. You can\n    extend the capabilities of text areas in your application by reopening this\n    class. For example, if you are building a Bootstrap project where `data-*`\n    attributes are used, you can globally add support for a `data-*` attribute\n    on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or\n    `Ember.TextSupport` and adding it to the `attributeBindings` concatenated\n    property:\n  \n    ```javascript\n    Ember.TextArea.reopen({\n      attributeBindings: ['data-error']\n    });\n    ```\n  \n    Keep in mind when writing `Ember.TextArea` subclasses that `Ember.TextArea`\n    itself extends `Ember.Component`. Expect isolated component semantics, not\n    legacy 1.x view semantics (like `controller` being present).\n  \n    See more about [Ember components](/api/classes/Ember.Component.html)\n  \n    @method textarea\n    @for Ember.Templates.helpers\n    @param {Hash} options\n    @public\n  */\n\n  /**\n    The internal class used to create textarea element when the `{{textarea}}`\n    helper is used.\n  \n    See [Ember.Templates.helpers.textarea](/api/classes/Ember.Templates.helpers.html#method_textarea)  for usage details.\n  \n    ## Layout and LayoutName properties\n  \n    Because HTML `textarea` elements do not contain inner HTML the `layout` and\n    `layoutName` properties will not be applied.

The first two\n    contexts to discuss are attribute context, and Handlebars value context.\n  \n    ```handlebars\n    {{! An example of attribute context }}\n    <div onclick={{action \"save\"}}></div>\n    {{! Examples of Handlebars value context }}\n    {{input on-input=(action \"save\")}}\n    {{yield (action \"refreshData\") andAnotherParam}}\n    ```\n  \n    In these contexts,\n    the helper is called a \"closure action\" helper. Its behavior is simple:\n    If passed a function name, read that function off the `actions` property\n    of the current context. Once that function is read (or if a function was\n    passed), create a closure over that function and any arguments.\n    The resulting value of an action helper used this way is simply a function.\n  \n    For example, in the attribute context:\n  \n    ```handlebars\n    {{! An example of attribute context }}\n    <div onclick={{action \"save\"}}></div>\n    ```\n  \n    The resulting template render logic would be:\n  \n    ```js\n    var div = document.createElement('div');\n    var actionFunction = (function(context){\n      return function() {\n        return context.actions.save.apply(context, arguments);\n      };\n    })(context);\n    div.onclick = actionFunction;\n    ```\n  \n    Thus when the div is clicked, the action on that context is called.\n    Because the `actionFunction` is just a function, closure actions can be\n    passed between components and still execute in the correct context.\n  \n    Here is an example action handler on a component:\n  \n    ```js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      actions: {\n        save() {\n          this.get('model').save();\n        }\n      }\n    });\n    ```\n  \n    Actions are always looked up on the `actions` property of the current context.\n    This avoids collisions in the naming of common actions, such as `destroy`.\n    Two options can be passed to the `action` helper when it is used in this way.\n  \n    * `target=someProperty` will look to `someProperty` instead of the current\n      context for the `actions` hash. This can be useful when targetting a\n      service for actions.\n    * `value=\"target.value\"` will read the path `target.value` off the first\n      argument to the action when it is called and rewrite the first argument\n      to be that value. This is useful when attaching actions to event listeners.\n  \n    ### Invoking an action\n  \n    Closure actions curry both their scope and any arguments. When invoked, any\n    additional arguments are added to the already curried list.\n    Actions should be invoked using the [sendAction](/api/classes/Ember.Component.html#method_sendAction)\n    method. The first argument to `sendAction` is the action to be called, and\n    additional arguments are passed to the action function. This has interesting\n    properties combined with currying of arguments. For example:\n  \n    ```js\n    export default Ember.Component.extend({\n      actions: {\n        // Usage {{input on-input=(action (action 'setName' model) value=\"target.value\")}}\n        setName(model, name) {\n          model.set('name', name);\n        }\n      }\n    });\n    ```\n  \n    The first argument (`model`) was curried over, and the run-time argument (`event`)\n    becomes a second argument. Action calls can be nested this way because each simply\n    returns a function. Any function can be passed to the `{{action}}` helper, including\n    other actions.\n  \n    Actions invoked with `sendAction` have the same currying behavior as demonstrated\n    with `on-input` above. For example:\n  \n    ```app/components/my-input.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      actions: {\n        setName(model, name) {\n          model.set('name', name);\n        }\n      }\n    });\n    ```\n  \n    ```handlebars\n    {{my-input submit=(action 'setName' model)}}\n    ```\n  \n    ```app/components/my-component.js\n    import Ember from 'ember';\n  \n    export default Ember.Component.extend({\n      click() {\n        // Note that model is not passed, it was curried in the template\n        this.sendAction('submit', 'bob');\n      }\n    });\n    ```\n  \n    ### Attaching actions to DOM elements\n  \n    The third context of the `{{action}}` helper can be called \"element space\".\n    For example:\n  \n    ```handlebars\n    {{! An example of element space }}\n    <div {{action \"save\"}}></div>\n    ```\n  \n    Used this way, the `{{action}}` helper provides a useful shortcut for\n    registering an HTML element in a template for a single DOM event and\n    forwarding that interaction to the template's context (controller or component).\n    If the context of a template is a controller, actions used this way will\n    bubble to routes when the controller does not implement the specified action.\n    Once an action hits a route, it will bubble through the route hierarchy.\n  \n    ### Event Propagation\n  \n    `{{action}}` helpers called in element space can control event bubbling. Note\n    that the closure style actions cannot.\n  \n    Events triggered through the action helper will automatically have\n    `.preventDefault()` called on them. You do not need to do so in your event\n    handlers. If you need to allow event propagation (to handle file inputs for\n    example) you can supply the `preventDefault=false` option to the `{{action}}` helper:\n  \n    ```handlebars\n    <div {{action \"sayHello\" preventDefault=false}}>\n      <input type=\"file\" />\n      <input type=\"checkbox\" />\n    </div>\n    ```\n  \n    To disable bubbling, pass `bubbles=false` to the helper:\n  \n    ```handlebars\n    <button {{action 'edit' post bubbles=false}}>Edit</button>\n    ```\n  \n    To disable bubbling with closure style actions you must create your own\n    wrapper helper that makes use of `event.stopPropagation()`:\n  \n    ```handlebars\n    <div onclick={{disable-bubbling (action \"sayHello\")}}>Hello</div>\n    ```\n  \n    ```app/helpers/disable-bubbling.js\n    import Ember from 'ember';\n  \n    export function disableBubbling([action]) {\n      return function(event) {\n        event.stopPropagation();\n        return action(event);\n      };\n    }\n    export default Ember.Helper.helper(disableBubbling);\n    ```\n  \n    If you need the default handler to trigger you should either register your\n    own event handler, or use event methods on your view class. See\n    [\"Responding to Browser Events\"](/api/classes/Ember.View.html#toc_responding-to-browser-events)\n    in the documentation for Ember.View for more information.\n  \n    ### Specifying DOM event type\n  \n    `{{action}}` helpers called in element space can specify an event type.\n    By default the `{{action}}` helper registers for DOM `click` events. You can\n    supply an `on` option to the helper to specify a different DOM event name:\n  \n    ```handlebars\n    <div {{action \"anActionName\" on=\"doubleClick\"}}>\n      click me\n    </div>\n    ```\n  \n    See [\"Event Names\"](/api/classes/Ember.View.html#toc_event-names) for a list of\n    acceptable DOM event names.\n  \n    ### Specifying whitelisted modifier keys\n  \n    `{{action}}` helpers called in element space can specify modifier keys.\n    By default the `{{action}}` helper will ignore click events with pressed modifier\n    keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.\n  \n    ```handlebars\n    <div {{action \"anActionName\" allowedKeys=\"alt\"}}>\n      click me\n    </div>\n    ```\n  \n    This way the action will fire when clicking with the alt key pressed down.\n    Alternatively, supply \"any\" to the `allowedKeys` option to accept any combination of modifier keys.\n  \n    ```handlebars\n    <div {{action \"anActionName\" allowedKeys=\"any\"}}>\n      click me with any key pressed\n    </div>\n    ```\n  \n    ### Specifying a Target\n  \n    A `target` option can be provided to the helper to change\n    which object will receive the method call. This option must be a path\n    to an object, accessible in the current context:\n  \n    ```app/templates/application.hbs\n    <div {{action \"anActionName\" target=someService}}>\n      click me\n    </div>\n    ```\n  \n    ```app/controllers/application.js\n    import Ember from 'ember';\n  \n    export default Ember.Controller.extend({\n      someService: Ember.inject.service()\n    });\n    ```\n  \n    @method action\n    @for Ember.Templates.helpers\n    @public\n  */\n\n  exports.default = function (vm, args) {\n    var named = args.named;\n    var positional = args.positional;\n\n    // The first two argument slots are reserved.\n    // pos[0] is the context (or `this`)\n    // pos[1] is the action name or function\n    // Anything else is an action argument.\n    var context = positional.at(0);\n    var action = positional.at(1);\n\n    // TODO: Is there a better way of doing this?\n    var debugKey = action._propertyKey;\n\n    var restArgs = undefined;\n\n    if (positional.length === 2) {\n      restArgs = _glimmerRuntime.EvaluatedPositionalArgs.empty();\n    } else {\n      restArgs = _glimmerRuntime.EvaluatedPositionalArgs.create(positional.values.slice(2));\n    }\n\n    var target = named.has('target') ? named.get('target') : context;\n    var processArgs = makeArgsProcessor(named.has('value') && named.get('value'), restArgs);\n\n    var fn = undefined;\n\n    if (typeof action[INVOKE] === 'function') {\n      fn = makeClosureAction(action, action, action[INVOKE], processArgs, debugKey);\n    } else if (_glimmerReference.isConst(target) && _glimmerReference.isConst(action)) {\n      fn = makeClosureAction(context.value(), target.value(), action.value(), processArgs, debugKey);\n    } else {\n      fn = makeDynamicClosureAction(context.value(), target, action, processArgs, debugKey);\n    }\n\n    fn[ACTION] = true;\n\n    return new _emberGlimmerUtilsReferences.UnboundReference(fn);\n  };\n\n  function NOOP(args) {\n    return args;\n  }\n\n  function makeArgsProcessor(valuePathRef, actionArgsRef) {\n    var mergeArgs = null;\n\n    if (actionArgsRef.length > 0) {\n      mergeArgs = function (args) {\n        return actionArgsRef.value().concat(args);\n      };\n    }\n\n    var readValue = null;\n\n    if (valuePathRef) {\n      readValue = function (args) {\n        var valuePath = valuePathRef.value();\n\n        if (valuePath && args.length > 0) {\n          args[0] = _emberMetal.get(args[0], valuePath);\n        }\n\n        return args;\n      };\n    }\n\n    if (mergeArgs && readValue) {\n      return function (args) {\n        return readValue(mergeArgs(args));\n      };\n    } else {\n      return mergeArgs || readValue || NOOP;\n    }\n  }\n\n  function makeDynamicClosureAction(context, targetRef, actionRef, processArgs, debugKey) {\n    // We don't allow undefined/null values, so this creates a throw-away action to trigger the assertions\n    _emberDebug.runInDebug(function () {\n      makeClosureAction(context, targetRef.value(), actionRef.value(), processArgs, debugKey);\n    });\n\n    return function () {\n      return makeClosureAction(context, targetRef.value(), actionRef.value(), processArgs, debugKey).apply(undefined, arguments);\n    };\n  }\n\n  function makeClosureAction(context, target, action, processArgs, debugKey) {\n    var self = undefined,\n        fn = undefined;\n\n    _emberDebug.assert('Action passed is null or undefined in (action) from ' + target + '.', !_emberMetal.isNone(action));\n\n    if (typeof action[INVOKE] === 'function') {\n      self = action;\n      fn = action[INVOKE];\n    } else {\n      var typeofAction = typeof action;\n\n      if (typeofAction === 'string') {\n        self = target;\n        fn = target.actions && target.actions[action];\n\n        _emberDebug.assert('An action named \\'' + action + '\\' was not found in ' + target, fn);\n      } else if (typeofAction === 'function') {\n        self = context;\n        fn = action;\n      } else {\n        _emberDebug.assert('An action could not be made for `' + (debugKey || action) + '` in ' + target + '.

See [Ember.Component](/api/classes/Ember.Component.html) for\n    additional information on how a `Component` functions.\n    `{{component}}`'s primary use is for cases where you want to dynamically\n    change which type of component is rendered as the state of your application\n    changes. This helper has three modes: inline, block, and nested.\n  \n    ### Inline Form\n  \n    Given the following template:\n  \n    ```app/application.hbs\n    {{component infographicComponentName}}\n    ```\n  \n    And the following application code:\n  \n    ```app/controllers/application.js\n    export default Ember.Controller.extend({\n      infographicComponentName: computed('isMarketOpen', {\n        get() {\n          if (this.get('isMarketOpen')) {\n            return 'live-updating-chart';\n          } else {\n            return 'market-close-summary';\n          }\n        }\n      })\n    });\n    ```\n  \n    The `live-updating-chart` component will be appended when `isMarketOpen` is\n    `true`, and the `market-close-summary` component will be appended when\n    `isMarketOpen` is `false`. If the value changes while the app is running,\n    the component will be automatically swapped out accordingly.\n    Note: You should not use this helper when you are consistently rendering the same\n    component. In that case, use standard component syntax, for example:\n  \n    ```app/templates/application.hbs\n    {{live-updating-chart}}\n    ```\n  \n    ### Block Form\n  \n    Using the block form of this helper is similar to using the block form\n    of a component. Given the following application template:\n  \n    ```app/templates/application.hbs\n    {{#component infographicComponentName}}\n      Last update: {{lastUpdateTimestamp}}\n    {{/component}}\n    ```\n  \n    The following controller code:\n  \n    ```app/controllers/application.js\n    export default Ember.Controller.extend({\n      lastUpdateTimestamp: computed(function() {\n        return new Date();\n      }),\n  \n      infographicComponentName: computed('isMarketOpen', {\n        get() {\n          if (this.get('isMarketOpen')) {\n            return 'live-updating-chart';\n          } else {\n            return 'market-close-summary';\n          }\n        }\n      })\n    });\n    ```\n  \n    And the following component template:\n  \n    ```app/templates/components/live-updating-chart.hbs\n    {{! chart }}\n    {{yield}}\n    ```\n  \n    The `Last Update: {{lastUpdateTimestamp}}` will be rendered in place of the `{{yield}}`.\n  \n    ### Nested Usage\n  \n    The `component` helper can be used to package a component path with initial attrs.\n    The included attrs can then be merged during the final invocation.\n    For example, given a `person-form` component with the following template:\n  \n    ```app/templates/components/person-form.hbs\n    {{yield (hash\n      nameInput=(component \"my-input-component\" value=model.name placeholder=\"First Name\")\n    )}}\n    ```\n  \n    When yielding the component via the `hash` helper, the component is invoked directly.\n    See the following snippet:\n  \n    ```\n    {{#person-form as |form|}}\n      {{form.nameInput placeholder=\"Username\"}}\n    {{/person-form}}\n    ```\n  \n    Which outputs an input whose value is already bound to `model.name` and `placeholder`\n    is \"Username\".\n  \n    When yielding the component without the hash helper use the `component` helper.\n    For example, below is a `full-name` component template:\n  \n    ```handlebars\n    {{yield (component \"my-input-component\" value=model.name placeholder=\"Name\")}}\n    ```\n  \n    ```\n    {{#full-name as |field|}}\n      {{component field placeholder=\"Full name\"}}\n    {{/full-name}}\n    ```\n  \n    @method component\n    @since 1.11.0\n    @for Ember.Templates.helpers\n    @public\n  */\n\n  var ClosureComponentReference = (function (_CachedReference) {\n    babelHelpers.inherits(ClosureComponentReference, _CachedReference);\n\n    ClosureComponentReference.create = function create(args, symbolTable, env) {\n      return new ClosureComponentReference(args, symbolTable, env);\n    };\n\n    function ClosureComponentReference(args, symbolTable, env) {\n      babelHelpers.classCallCheck(this, ClosureComponentReference);\n\n      _CachedReference.call(this);\n\n      var firstArg = args.positional.at(0);\n      this.defRef = firstArg;\n      this.tag = firstArg.tag;\n      this.env = env;\n      this.symbolTable = symbolTable;\n      this.args = args;\n      this.lastDefinition = undefined;\n      this.lastName = undefined;\n    }\n\n    ClosureComponentReference.prototype.compute = function compute() {\n      // TODO: Figure out how to extract this because it's nearly identical to\n      // DynamicComponentReference::compute().

It is an extension\n    of the base Handlebars `{{#each}}` helper.\n    The default behavior of `{{#each}}` is to yield its inner block once for every\n    item in an array passing the item as the first block parameter.\n  \n    ```javascript\n    var developers = [{ name: 'Yehuda' },{ name: 'Tom' }, { name: 'Paul' }];\n    ```\n  \n    ```handlebars\n    {{#each developers key=\"name\" as |person|}}\n      {{person.name}}\n      {{! `this` is whatever it was outside the #each }}\n    {{/each}}\n    ```\n  \n    The same rules apply to arrays of primitives.\n  \n    ```javascript\n    var developerNames = ['Yehuda', 'Tom', 'Paul']\n    ```\n  \n    ```handlebars\n    {{#each developerNames key=\"@index\" as |name|}}\n      {{name}}\n    {{/each}}\n    ```\n  \n    During iteration, the index of each item in the array is provided as a second block parameter.\n  \n    ```handlebars\n    <ul>\n      {{#each people as |person index|}}\n        <li>Hello, {{person.name}}!

By helping Ember\n    detect that some elements in the array are the same, DOM elements can be\n    re-used, significantly improving rendering speed.\n  \n    For example, here's the `{{#each}}` helper with its `key` set to `id`:\n  \n    ```handlebars\n    {{#each model key=\"id\" as |item|}}\n    {{/each}}\n    ```\n  \n    When this `{{#each}}` re-renders, Ember will match up the previously rendered\n    items (and reorder the generated DOM elements) based on each item's `id`\n    property.\n    By default the item's own reference is used.\n  \n    ### {{else}} condition\n  \n    `{{#each}}` can have a matching `{{else}}`.

context (e.g. child component), you are saying that changing that\n    property in the inner context does not change the value in the outer context.\n  \n    To specify that a binding is read-only, when invoking the child `Component`:\n  \n    ```app/components/my-parent.js\n    export default Component.extend({\n      totalClicks: 3\n    });\n    ```\n  \n    ```app/templates/components/my-parent.hbs\n    {{log totalClicks}} // -> 3\n    {{my-child childClickCount=(readonly totalClicks)}}\n    ```\n  \n    Now, when you update `childClickCount`:\n  \n

array) instead of a primitive object (e.g. number, string),\n    only the reference to the object is protected using the readonly helper.\n    This means that you can change properties of the object both on the parent component, as well as the child component.\n    The `readonly` binding behaves similar to the `const` keyword in JavaScript.\n  \n    Let's look at an example:\n  \n    First let's set up the parent component:\n  \n    ```app/components/my-parent.js\n    export default Ember.Component.extend({\n      clicks: null,\n  \n      init() {\n        this._super(...arguments);\n

```\n  \n    Now, if you update the `total` property of `childClicks`:\n  \n    ```app/components/my-child.js\n    export default Ember.Component.extend({\n      click() {\n        this.get('clicks').incrementProperty('total');\n      }\n    });\n    ```\n  \n    You will see the following happen:\n  \n    ```app/templates/components/my-parent.hbs\n    {{log clicks.total}} //-> 4\n    {{my-child childClicks=(readonly clicks)}}\n    ```\n  \n    ```app/templates/components/my-child.hbs\n    {{log childClicks.total}} //-> 4\n    ```\n  \n    @method readonly\n    @param

For example, given a component with the property \"name\",\n    that component's template can use the name in several ways:\n  \n    ```app/components/person.js\n      export default Ember.Component.extend({\n        name: 'Jill'\n      });\n    ```\n  \n    ```app/components/person.hbs\n    {{name}}\n    <div>{{name}}</div>\n    <span data-name={{name}}></span>\n    ```\n  \n    Any time the \"name\" property on the component changes, the DOM will be\n    updated.\n  \n    Properties can be chained as well:\n  \n    ```handlebars\n    {{aUserModel.name}}\n    <div>{{listOfUsers.firstObject.name}}</div>\n    ```\n  \n    ### Using Ember helpers\n  \n    When content is passed in mustaches `{{}}`, Ember will first try to find a helper\n    or component with that name. For example, the `if` helper:\n  \n    ```handlebars\n    {{if name \"I have a name\" \"I have no name\"}}\n    <span data-has-name={{if name true}}></span>\n    ```\n  \n    The returned value is placed where the `{{}}` is called. The above style is\n    called \"inline\". A second style of helper usage is called \"block\". For example:\n  \n    ```handlebars\n    {{#if name}}\n    I have a name\n    {{else}}\n    I have no name\n    {{/if}}\n    ```\n  \n    The block form of helpers allows you to control how the UI is created based\n    on the values of properties.\n    A third form of helper is called \"nested\". For example here the concat\n    helper will add \" Doe\" to a displayed name if the person has no last name:\n  \n    ```handlebars\n    <span data-name={{concat firstName (\n    if lastName (concat \" \" lastName) \"Doe\"\n    )}}></span>\n    ```\n  \n    Ember's built-in helpers are described under the [Ember.Templates.helpers](/api/classes/Ember.Templates.helpers.html)\n    namespace. Documentation on creating custom helpers can be found under\n    [Ember.Helper](/api/classes/Ember.Helper.html).\n  \n    ### Invoking a Component\n  \n    Ember components represent state to the UI of an application. Further\n    reading on components can be found under [Ember.Component](/api/classes/Ember.Component.html).\n  \n    @module ember\n    @submodule ember-glimmer\n    @main ember-glimmer\n    @public\n   */\n\n  /**\n    Use the `{{with}}` helper when you want to alias a property to a new name. This is helpful\n    for semantic clarity as it allows you to retain default scope or to reference a property from another\n    `{{with}}` block.\n  \n    If the aliased property is \"falsey\", for example: `false`, `undefined` `null`, `\"\"`, `0`, NaN or\n    an empty array, the block will not be rendered.\n  \n    ```handlebars\n    {{! Will only render if user.posts contains items}}\n    {{#with user.posts as |blogPosts|}}\n      <div class=\"notice\">\n        There are {{blogPosts.length}} blog posts written by {{user.name}}.\n      </div>\n      {{#each blogPosts as |post|}}\n        <li>{{post.title}}</li>\n      {{/each}}\n    {{/with}}\n    ```\n  \n    Without the `as` operator, it would be impossible to reference `user.name` in the example above.\n  \n    NOTE: The alias should not reuse a name from the bound property path.\n  \n    For example: `{{#with foo.bar as |foo|}}` is not supported because it attempts to alias using\n    the first part of the property path, `foo`.

  The `{{input}}` helper lets you create an HTML `<input />` component.\n    It causes an `Ember.TextField` component to be rendered.  For more info,\n    see the [Ember.TextField](/api/classes/Ember.TextField.html) docs and\n    the [templates guide](http://emberjs.com/guides/templates/input-helpers/).\n  \n    ```handlebars\n    {{input value=\"987\"}}\n    ```\n  \n    renders as:\n  \n    ```HTML\n    <input type=\"text\" value=\"987\" />\n    ```\n  \n    ### Text field\n  \n    If no `type` option is specified, a default of type 'text' is used.\n    Many of the standard HTML attributes may be passed to this helper.\n    <table>\n      <tr><td>`readonly`</td><td>`required`</td><td>`autofocus`</td></tr>\n      <tr><td>`value`</td><td>`placeholder`</td><td>`disabled`</td></tr>\n      <tr><td>`size`</td><td>`tabindex`</td><td>`maxlength`</td></tr>\n      <tr><td>`name`</td><td>`min`</td><td>`max`</td></tr>\n      <tr><td>`pattern`</td><td>`accept`</td><td>`autocomplete`</td></tr>\n      <tr><td>`autosave`</td><td>`formaction`</td><td>`formenctype`</td></tr>\n      <tr><td>`formmethod`</td><td>`formnovalidate`</td><td>`formtarget`</td></tr>\n      <tr><td>`height`</td><td>`inputmode`</td><td>`multiple`</td></tr>\n      <tr><td>`step`</td><td>`width`</td><td>`form`</td></tr>\n      <tr><td>`selectionDirection`</td><td>`spellcheck`</td><td>&nbsp;</td></tr>\n    </table>\n    When set to a quoted string, these values will be directly applied to the HTML\n    element. When left unquoted, these values will be bound to a property on the\n    template's current rendering context (most typically a controller instance).\n    A very common use of this helper is to bind the `value` of an input to an Object's attribute:\n  \n    ```handlebars\n    Search:\n    {{input value=searchWord}}\n    ```\n  \n    In this example, the inital value in the `<input />` will be set to the value of `searchWord`.\n    If the user changes the text, the value of `searchWord` will also be updated.\n  \n    ### Actions\n  \n    The helper can send multiple actions based on user events.\n    The action property defines the action which is sent when\n    the user presses the return key.\n  \n    ```handlebars\n    {{input action=\"submit\"}}\n    ```\n  \n    The helper allows some user events to send actions.\n  \n    * `enter`\n    * `insert-newline`\n    * `escape-press`\n    * `focus-in`\n    * `focus-out`\n    * `key-press`\n    * `key-up`\n  \n    For example, if you desire an action to be sent when the input is blurred,\n    you only need to setup the action name to the event name property.\n  \n    ```handlebars\n    {{input focus-out=\"alertMessage\"}}\n    ```\n    See more about [Text Support Actions](/api/classes/Ember.TextField.html)\n  \n    ### Extending `Ember.TextField`\n  \n    Internally, `{{input type=\"text\"}}` creates an instance of `Ember.TextField`, passing\n    arguments from the helper to `Ember.TextField`'s `create` method. You can extend the\n    capabilities of text inputs in your applications by reopening this class. For example,\n    if you are building a Bootstrap project where `data-*` attributes are used, you\n    can add one to the `TextField`'s `attributeBindings` property:\n  \n    ```javascript\n    Ember.TextField.reopen({\n      attributeBindings: ['data-error']\n    });\n    ```\n  \n    Keep in mind when writing `Ember.TextField` subclasses that `Ember.TextField`\n    itself extends `Ember.Component`. Expect isolated component semantics, not\n    legacy 1.x view semantics (like `controller` being present).\n    See more about [Ember components](/api/classes/Ember.Component.html)\n  \n    ### Checkbox\n  \n    Checkboxes are special forms of the `{{input}}` helper.  To create a `<checkbox />`:\n  \n    ```handlebars\n    Emberize Everything:\n    {{input type=\"checkbox\" name=\"isEmberized\" checked=isEmberized}}\n    ```\n  \n    This will bind checked state of this checkbox to the value of `isEmberized`  -- if either one changes,\n    it will be reflected in the other.\n  \n    The following HTML attributes can be set via the helper:\n  \n    * `checked`\n    * `disabled`\n    * `tabindex`\n    * `indeterminate`\n    * `name`\n    * `autofocus`\n    * `form`\n  \n    ### Extending `Ember.Checkbox`\n  \n    Internally, `{{input type=\"checkbox\"}}` creates an instance of `Ember.Checkbox`, passing\n    arguments from the helper to `Ember.Checkbox`'s `create` method. You can extend the\n    capablilties of checkbox inputs in your applications by reopening this class. For example,\n    if you wanted to add a css class to all checkboxes in your application:\n  \n    ```javascript\n    Ember.Checkbox.reopen({\n      classNames: ['my-app-checkbox']\n    });\n    ```\n

also will be used.\n    Note: A given controller may only be used *once* in your app in this manner.\n    A singleton instance of the controller will be created for you.\n  \n    Example:\n  \n    ```javascript\n    App.NavigationController = Ember.Controller.extend({\n      who: \"world\"\n    });\n    ```\n  \n    ```handlebars\n    <!-- navigation.hbs -->\n    Hello, {{who}}.\n    ```\n  \n

world.\n    </div>\n    ```\n  \n    Optionally you may provide a second argument: a property path\n    that will be bound to the `model` property of the controller.\n    If a `model` property path is specified, then a new instance of the\n    controller will be created and `{{render}}` can be used multiple times\n    with the same name.\n  \n    For example if you had this `author` template.\n  \n    ```handlebars\n    <div class=\"author\">\n      Written by {{firstName}} {{lastName}}.\n      Total Posts: {{postCount}}\n    </div>\n    ```\n  \n    You could render it inside the `post` template using the `render` helper.\n  \n    ```handlebars\n    <div class=\"post\">\n      <h1>{{title}}</h1>\n      <div>{{body}}</div>\n      {{render \"author\" author}}\n    </div>\n    ```\n  \n

The value of this property should be a string representing a path\n    to another object or a custom binding instance created using Binding helpers\n    (see \"One Way Bindings\"):\n  \n    ```\n    valueBinding: \"MyApp.someController.title\"\n    ```\n  \n    This will create a binding from `MyApp.someController.title` to the `value`\n    property of your object instance automatically. Now the two values will be\n    kept in sync.\n  \n    ## One Way Bindings\n  \n    One especially useful binding customization you can use is the `oneWay()`\n    helper. This helper tells Ember that you are only interested in\n    receiving changes on the object you are binding from. For example, if you\n    are binding to a preference and you want to be notified if the preference\n    has changed, but your object will not be changing the preference itself, you\n    could do:\n  \n    ```\n    bigTitlesBinding: Ember.Binding.oneWay(\"MyApp.preferencesController.bigTitles\")\n    ```\n  \n    This way if the value of `MyApp.preferencesController.bigTitles` changes the\n    `bigTitles` property of your object will change also. However, if you\n    change the value of your `bigTitles` property, it will not update the\n    `preferencesController`.\n  \n    One way bindings are almost twice as fast to setup and twice as fast to\n    execute because the binding only has to worry about changes to one side.\n  \n    You should consider using one way bindings anytime you have an object that\n    may be created frequently and you do not intend to change a property; only\n    to monitor it for changes (such as in the example above).\n  \n    ## Adding Bindings Manually\n  \n    All of the examples above show you how to configure a custom binding, but the\n    result of these customizations will be a binding template, not a fully active\n    Binding instance. The binding will actually become active only when you\n    instantiate the object the binding belongs to. It is useful, however, to\n    understand what actually happens when the binding is activated.\n  \n    For a binding to function it must have at least a `from` property and a `to`\n    property. The `from` property path points to the object/key that you want to\n    bind from while the `to` path points to the object/key you want to bind to.\n  \n    When you define a custom binding, you are usually describing the property\n    you want to bind from (such as `MyApp.someController.value` in the examples\n    above). When your object is created, it will automatically assign the value\n    you want to bind `to` based on the name of your binding key. In the\n    examples above, during init, Ember objects will effectively call\n    something like this on your binding:\n  \n    ```javascript\n    binding = Ember.Binding.from(\"valueBinding\").to(\"value\");\n    ```\n  \n    This creates a new binding instance based on the template you provide, and\n    sets the to path to the `value` property of the new object. Now that the\n    binding is fully configured with a `from` and a `to`, it simply needs to be\n    connected to become active. This is done through the `connect()` method:\n  \n    ```javascript\n    binding.connect(this);\n    ```\n  \n    Note that when you connect a binding you pass the object you want it to be\n    connected to. This object will be used as the root for both the from and\n    to side of the binding when inspecting relative paths. This allows the\n    binding to be automatically inherited by subclassed objects as well.\n  \n    This also allows you to bind between objects using the paths you declare in\n    `from` and `to`:\n  \n    ```javascript\n    // Example 1\n    binding = Ember.Binding.from(\"App.someObject.value\").to(\"value\");\n    binding.connect(this);\n  \n    // Example 2\n    binding = Ember.Binding.from(\"parentView.value\").to(\"App.someObject.value\");\n    binding.connect(this);\n    ```\n  \n    Now that the binding is connected, it will observe both the from and to side\n    and relay changes.\n  \n    If you ever needed to do so (you almost never will, but it is useful to\n    understand this anyway), you could manually create an active binding by\n    using the `Ember.bind()` helper method.

You can specify various properties\n    that your computed property depends on. This will force the cached\n    result to be recomputed if the dependencies are modified.\n  \n    In the following example we declare a computed property - `fullName` - by calling\n    `.Ember.computed()` with property dependencies (`firstName` and `lastName`) as leading arguments and getter accessor function. The `fullName` getter function\n    will be called once (regardless of how many times it is accessed) as long\n    as its dependencies have not changed. Once `firstName` or `lastName` are updated\n    any future calls (or anything bound) to `fullName` will incorporate the new\n    values.\n  \n    ```javascript\n    let Person = Ember.Object.extend({\n      // these will be supplied by `create`\n      firstName: null,\n      lastName: null,\n  \n      fullName: Ember.computed('firstName', 'lastName', function() {\n        let firstName = this.get('firstName'),\n            lastName  = this.get('lastName');\n  \n        return firstName + ' ' + lastName;\n      })\n    });\n  \n    let tom = Person.create({\n      firstName: 'Tom',\n      lastName: 'Dale'\n    });\n  \n    tom.get('fullName') // 'Tom Dale'\n    ```\n  \n    You can also define what Ember should do when setting a computed property by providing additional function (`set`) in hash argument.\n    If you try to set a computed property, it will try to invoke setter accessor function with the key and\n    value you want to set it to as arguments.\n  \n    ```javascript\n    let Person = Ember.Object.extend({\n      // these will be supplied by `create`\n      firstName: null,\n      lastName: null,\n  \n      fullName: Ember.computed('firstName', 'lastName', {\n        get(key) {\n          let firstName = this.get('firstName'),\n              lastName  = this.get('lastName');\n  \n          return firstName + ' ' + lastName;\n        },\n        set(key, value) {\n          let [firstName, lastName] = value.split(' ');\n  \n          this.set('firstName', firstName);\n          this.set('lastName', lastName);\n  \n          return value;\n        }\n      })\n    });\n  \n    let person = Person.create();\n  \n    person.set('fullName', 'Peter Wagenet');\n    person.get('firstName'); // 'Peter'\n    person.get('lastName');  // 'Wagenet'\n    ```\n  \n    You can overwrite computed property with normal property (no longer computed), that won't change if dependencies change, if you set computed property and it won't have setter accessor function defined.\n  \n    You can also mark computed property as `.readOnly()` and block all attempts to set it.\n  \n    ```javascript\n    let Person = Ember.Object.extend({\n      // these will be supplied by `create`\n      firstName: null,\n      lastName: null,\n  \n      fullName: Ember.computed('firstName', 'lastName', {\n        get(key) {\n          let firstName = this.get('firstName');\n          let lastName  = this.get('lastName');\n  \n          return firstName + ' ' + lastName;\n        }\n      }).readOnly()\n    });\n  \n    let person = Person.create();\n    person.set('fullName', 'Peter Wagenet'); // Uncaught Error: Cannot set read-only property \"fullName\" on object: <(...):emberXXX>\n    ```\n  \n    Additional resources:\n    - [New CP syntax RFC](https://github.com/emberjs/rfcs/blob/master/text/0011-improved-cp-syntax.md)\n    - [New computed syntax explained in \"Ember 1.12 released\" ](http://emberjs.com/blog/2015/05/13/ember-1-12-released.html#toc_new-computed-syntax)\n  \n    @class ComputedProperty\n    @namespace Ember\n    @public\n  */\n  function ComputedProperty(config, opts) {\n    this.isDescriptor = true;\n    if (typeof config === 'function') {\n      this._getter = config;\n    } else {\n      _emberDebug.assert('Ember.computed expects a function or an object as last argument.', typeof config === 'object' && !Array.isArray(config));\n      _emberDebug.assert('Config object passed to an Ember.computed can only contain `get` or `set` keys.', (function () {\n        var keys = Object.keys(config);\n        for (var i = 0; i < keys.length; i++) {\n          if (keys[i] !== 'get' && keys[i] !== 'set') {\n            return false;\n          }\n        }\n        return true;\n      })());\n      this._getter = config.get;\n      this._setter = config.set;\n    }\n    _emberDebug.assert('Computed properties must receive a getter or a setter, you passed none.', !!this._getter || !!this._setter);\n    this._dependentKeys = undefined;\n    this._suspended = undefined;\n    this._meta = undefined;\n    this._volatile = false;\n    this._dependentKeys = opts && opts.dependentKeys;\n    this._readOnly = false;\n  }\n\n  ComputedProperty.prototype = new _emberMetalProperties.Descriptor();\n  ComputedProperty.prototype.constructor = ComputedProperty;\n\n  var ComputedPropertyPrototype = ComputedProperty.prototype;\n\n  /**\n    Call on a computed property to set it into non-cached mode.

Ember.subscribe(\"render\", {\n      before(name, timestamp, payload) {\n  \n      },\n  \n      after(name, timestamp, payload) {\n  \n      }\n    });\n    ```\n  \n    If you return a value from the `before` callback, that same\n    value will be passed as a fourth parameter to the `after`\n    callback.\n  \n    Instrument a block of code by using `Ember.instrument`:\n  \n    ```javascript\n    Ember.instrument(\"render.handlebars\", payload, function() {\n      // rendering logic\n    }, binding);\n    ```\n  \n    Event names passed to `Ember.instrument` are namespaced\n    by periods, from more general to more specific. Subscribers\n    can listen for events by whatever level of granularity they\n    are interested in.\n  \n    In the above example, the event is `render.handlebars`,\n    and the subscriber listened for all events beginning with\n    `render`.

This is equivalent to calling\n    `run.later` with a wait time of 1ms.\n  \n    ```javascript\n    run.next(myContext, function() {\n      // code to be executed in the next run loop,\n      // which will be scheduled after the current one\n    });\n    ```\n  \n    Multiple operations scheduled with `run.next` will coalesce\n    into the same later run loop, along with any other operations\n    scheduled by `run.later` that expire right around the same\n    time that `run.next` operations will fire.\n  \n    Note that there are often alternatives to using `run.next`.\n    For instance, if you'd like to schedule an operation to happen\n    after all DOM element operations have completed within the current\n    run loop, you can make use of the `afterRender` run loop queue (added\n    by the `ember-views` package, along with the preceding `render` queue\n    where all the DOM element operations happen).\n  \n    Example:\n  \n    ```javascript\n    export default Ember.Component.extend({\n      didInsertElement() {\n        this._super(...arguments);\n        run.scheduleOnce('afterRender', this, 'processChildElements');\n      },\n  \n      processChildElements() {\n        // ... do something with component's child component\n        // elements after they've finished rendering, which\n        // can't be done within this component's\n        // `didInsertElement` hook because that gets run\n        // before the child elements have been added to the DOM.\n      }\n    });\n    ```\n  \n    One benefit of the above approach compared to using `run.next` is\n    that you will be able to perform DOM/CSS operations before unprocessed\n    elements are rendered to the screen, which may prevent flickering or\n    other artifacts caused by delaying processing until after rendering.\n  \n    The other major benefit to the above approach is that `run.next`\n    introduces an element of non-determinism, which can make things much\n    harder to test, due to its reliance on `setTimeout`; it's much harder\n    to guarantee the order of scheduled operations when they are scheduled\n    outside of the current run loop, i.e. with `run.next`.\n  \n    @method next\n    @param {Object} [target] target of method to invoke\n    @param {Function|String} method The method to invoke.\n      If you pass a string it will be resolved on the\n      target at the time the method is invoked.\n    @param {Object} [args*] Optional arguments to pass to the timeout.\n    @return {Object} Timer information for use in cancelling, see `run.cancel`.\n    @public\n  */\n  run.next = function () {\n    for (var _len4 = arguments.length, args = Array(_len4), _key4 = 0; _key4 < _len4; _key4++) {\n      args[_key4] = arguments[_key4];\n    }\n\n    args.push(1);\n    return backburner.later.apply(backburner, args);\n  };\n\n  /**\n    Cancels a scheduled item.

This relies upon the browser's `history` API.\n  \n    Example:\n  \n    ```javascript\n    App.Router.map(function() {\n      this.route('posts', function() {\n        this.route('new');\n      });\n    });\n  \n    App.Router.reopen({\n      location: 'history'\n    });\n    ```\n  \n    This will result in a posts.new url of `/posts/new`.\n  \n    Keep in mind that your server must serve the Ember app at all the routes you\n    define.\n  \n    ### AutoLocation\n  \n    Using `AutoLocation`, the router will use the best Location class supported by\n    the browser it is running in.\n  \n    Browsers that support the `history` API will use `HistoryLocation`, those that\n    do not, but still support the `hashchange` event will use `HashLocation`, and\n    in the rare case neither is supported will use `NoneLocation`.\n  \n    Example:\n  \n    ```javascript\n    App.Router.map(function() {\n      this.route('posts', function() {\n        this.route('new');\n      });\n    });\n  \n    App.Router.reopen({\n      location: 'auto'\n    });\n    ```\n  \n    This will result in a posts.new url of `/posts/new` for modern browsers that\n    support the `history` api or `/#/posts/new` for older ones, like Internet\n    Explorer 9 and below.\n  \n    When a user visits a link to your application, they will be automatically\n    upgraded or downgraded to the appropriate `Location` class, with the URL\n    transformed accordingly, if needed.\n  \n    Keep in mind that since some of your users will use `HistoryLocation`, your\n    server must serve the Ember app at all the routes you define.\n  \n    ### NoneLocation\n  \n    Using `NoneLocation` causes Ember to not store the applications URL state\n    in the actual URL. This is generally used for testing purposes, and is one\n    of the changes made when calling `App.setupForTesting()`.\n  \n    ## Location API\n  \n    Each location implementation must provide the following methods:\n  \n    * implementation: returns the string name used to reference the implementation.\n    * getURL: returns the current URL.\n    * setURL(path): sets the current URL.\n    * replaceURL(path): replace the current URL (optional).\n    * onUpdateURL(callback): triggers the callback when the URL changes.\n    * formatURL(url): formats `url` to be placed into `href` attribute.\n    * detect() (optional): instructs the location to do any feature detection\n        necessary. If the location needs to redirect to a different URL, it\n        can cancel routing by setting the `cancelRouterSetup` property on itself\n        to `false`.\n  \n    Calling setURL or replaceURL will not trigger onUpdateURL callbacks.\n  \n    ## Custom implementation\n  \n    Ember scans `app/locations/*` for extending the Location API.\n  \n    Example:\n  \n    ```javascript\n    import Ember from 'ember';\n  \n    export default Ember.HistoryLocation.extend({\n      implementation: 'history-url-logging',\n  \n      pushState: function (path) {\n        console.log(path);\n        this._super.apply(this, arguments);\n      }\n    });\n    ```\n  \n    @class Location\n    @namespace Ember\n    @static\n    @private\n  */\n  exports.default = {\n    /**\n     This is deprecated in favor of using the container to lookup the location\n     implementation as desired.\n      For example:\n      ```javascript\n     // Given a location registered as follows:\n     container.register('location:history-test', HistoryTestLocation);\n      // You could create a new instance via:\n     container.lookup('location:history-test');\n     ```\n       @method create\n      @param {Object} options\n      @return {Object} an instance of an implementation of the `location` API\n      @deprecated Use the container to lookup the location implementation that you\n      need.\n      @private\n    */\n    create: function (options) {\n      var implementation = options && options.implementation;\n      _emberDebug.assert('Ember.Location.create: you must specify a \\'implementation\\' option', !!implementation);\n\n      var implementationClass = this.implementations[implementation];\n      _emberDebug.assert('Ember.Location.create: ' + implementation + ' is not a valid implementation', !!implementationClass);\n\n      return implementationClass.create.apply(implementationClass, arguments);\n    },\n\n    implementations: {},\n    _location: _emberEnvironment.environment.location,\n\n    /**\n      Returns the current `location.hash` by parsing location.href since browsers\n      inconsistently URL-decode `location.hash`.\n       https://bugzilla.mozilla.org/show_bug.cgi?id=483304\n       @private\n      @method getHash\n      @since 1.4.0\n    */\n    _getHash: function () {\n      return _emberRoutingLocationUtil.getHash(this.location);\n    }\n  };\n});\nenifed('ember-routing/location/auto_location', ['exports', 'ember-utils', 'ember-metal', 'ember-debug', 'ember-runtime', 'ember-environment', 'ember-routing/location/util'], function (exports, _emberUtils, _emberMetal, _emberDebug, _emberRuntime, _emberEnvironment, _emberRoutingLocationUtil) {\n  'use strict';\n\n  exports.getHistoryPath = getHistoryPath;\n  exports.getHashPath = getHashPath;\n\n  /**\n  @module ember\n  @submodule ember-routing\n  */\n\n  /**\n    Ember.AutoLocation will select the best location option based off browser\n    support with the priority order: history, hash, none.\n  \n    Clean pushState paths accessed by hashchange-only browsers will be redirected\n    to the hash-equivalent and vice versa so future transitions are consistent.\n  \n    Keep in mind that since some of your users will use `HistoryLocation`, your\n    server must serve the Ember app at all the routes you define.\n  \n    @class AutoLocation\n    @namespace Ember\n    @static\n    @private\n  */\n  exports.default = _emberRuntime.Object.extend({\n    /**\n      @private\n       The browser's `location` object.

See\n      Ember.Resolver for how these are mapped to JavaScript objects in your\n      application. The template to render into needs to be related to  either the\n      current route or one of its ancestors.\n       Not all options need to be passed to `render`. Default values will be used\n      based on the name of the route specified in the router or the Route's\n      `controllerName` and `templateName` properties.\n       For example:\n       ```app/router.js\n      // ...\n       Router.map(function() {\n        this.route('index');\n        this.route('post', { path: '/posts/:post_id' });\n      });\n       export default Router;\n      ```\n       ```app/routes/post.js\n      import Ember from 'ember';\n       export default Ember.Route.extend({\n        renderTemplate() {\n          this.render(); // all defaults apply\n        }\n      });\n      ```\n       The name of the route, defined by the router, is `post`.\n       The following equivalent default options will be applied when\n      the Route calls `render`:\n       ```javascript\n      this.render('post', {  // the template name associated with 'post' Route\n        into: 'application', // the parent route to 'post' Route\n        outlet: 'main',      // {{outlet}} and {{outlet 'main'}} are synonymous,\n        controller: 'post',  // the controller associated with the 'post' Route\n      })\n      ```\n       By default the controller's `model` will be the route's model, so it does not\n      need to be passed unless you wish to change which model is being used.\n       @method render\n      @param {String} name the name of the template to render\n      @param {Object} [options] the options\n      @param {String} [options.into] the template to render into,\n                      referenced by name.

It is not a\n    concrete implementation, but it can be used up by other classes that want\n    to appear like arrays.\n  \n    For example, ArrayProxy is a concrete classes that can\n    be instantiated to implement array-like behavior. Both of these classes use\n    the Array Mixin by way of the MutableArray mixin, which allows observable\n    changes to be made to the underlying array.\n  \n    Unlike `Ember.Enumerable,` this mixin defines methods specifically for\n    collections that provide index-ordered access to their contents. When you\n    are designing code that needs to accept any kind of Array-like object, you\n    should use these methods instead of Array primitives because these will\n    properly notify observers of changes to the array.\n  \n    Although these methods are efficient, they do add a layer of indirection to\n    your application so it is a good idea to use them only when you need the\n    flexibility of using both true JavaScript arrays and \"virtual\" arrays such\n    as controllers and collections.\n  \n    You can use the methods defined in this module to access and modify array\n    contents in a KVO-friendly way. You can also be notified whenever the\n    membership of an array changes by using `.observes('myArray.[]')`.\n  \n    To support `Ember.Array` in your own class, you must override two\n    primitives to use it: `length()` and `objectAt()`.\n  \n    Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`\n    mixin.

You must have a length property. This property should change whenever\n       the number of items in your enumerable object changes.

This is often where the most common API conflicts occur.\n    Ember's API is designed to be as friendly as possible with other\n    libraries by implementing only methods that mostly correspond to the\n    JavaScript 1.8 API.\n  \n    @class Enumerable\n    @namespace Ember\n    @since Ember 0.9\n    @private\n  */\n  var Enumerable = _emberMetal.Mixin.create({\n\n    /**\n      __Required.__ You must implement this method to apply this mixin.\n       Implement this method to make your class enumerable.\n       This method will be called repeatedly during enumeration.

This is a useful way to\n      manage iteration if you are tracing a linked list, for example.\n       Finally the context parameter will always contain a hash you can use as\n      a \"scratchpad\" to maintain any other state you need in order to iterate\n      properly.

Once an object is frozen it should be read only. No changes\n    may be made the internal state of the object.\n  \n    ## Enforcement\n  \n    To fully support freezing in your subclass, you must include this mixin and\n    override any method that might alter any property on the object to instead\n    raise an exception. You can check the state of an object by checking the\n    `isFrozen` property.\n  \n    Although future versions of JavaScript may support language-level freezing\n    object objects, that is not the case today. Even if an object is freezable,\n    it is still technically possible to modify the object, even though it could\n    break other parts of your application that do not expect a frozen object to\n    change. It is, therefore, very important that you always respect the\n    `isFrozen` property on all freezable objects.\n  \n    ## Example Usage\n  \n    The example below shows a simple object that implement the `Ember.Freezable`\n    protocol.\n  \n    ```javascript\n    Contact = Ember.Object.extend(Ember.Freezable, {\n      firstName: null,\n      lastName: null,\n  \n      // swaps the names\n      swapNames: function() {\n        if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;\n        var tmp = this.get('firstName');\n        this.set('firstName', this.get('lastName'));\n        this.set('lastName', tmp);\n        return this;\n      }\n  \n    });\n  \n    c = Contact.create({ firstName: \"John\", lastName: \"Doe\" });\n    c.swapNames();  // returns c\n    c.freeze();\n    c.swapNames();  // EXCEPTION\n    ```\n  \n    ## Copying\n  \n    Usually the `Ember.Freezable` protocol is implemented in cooperation with the\n    `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will\n    return a frozen object, if the object implements this method as well.\n  \n    @class Freezable\n    @namespace Ember\n    @since Ember 0.9\n    @deprecated Use `Object.freeze` instead.\n    @private\n  */\n  var Freezable = _emberMetal.Mixin.create({\n\n    init: function () {\n      _emberDebug.deprecate('`Ember.Freezable` is deprecated, use `Object.freeze` instead.', false, { id: 'ember-runtime.freezable-init', until: '3.0.0' });\n      this._super.apply(this, arguments);\n    },\n\n    /**\n      Set to `true` when the object is frozen.

This is one of the fundamental ways that\n    models, controllers and views communicate with each other in an Ember\n    application.\n  \n    Any object that has this mixin applied can be used in observer\n    operations. That includes `Ember.Object` and most objects you will\n    interact with as you write your Ember application.\n  \n    Note that you will not generally apply this mixin to classes yourself,\n    but you will use the features provided by this module frequently, so it\n    is important to understand how to use it.\n  \n    ## Using `get()` and `set()`\n  \n    Because of Ember's support for bindings and observers, you will always\n    access properties using the get method, and set properties using the\n    set method. This allows the observing objects to be notified and\n    computed properties to be handled properly.\n  \n    More documentation about `get` and `set` are below.\n  \n    ## Observing Property Changes\n  \n    You typically observe property changes simply by using the `Ember.observer`\n    function in classes that you write.\n  \n    For example:\n  \n    ```javascript\n    Ember.Object.extend({\n      valueObserver: Ember.observer('value', function(sender, key, value, rev) {\n        // Executes whenever the \"value\" property changes\n        // See the addObserver method for more information about the callback arguments\n      })\n    });\n    ```\n  \n    Although this is the most common way to add an observer, this capability\n    is actually built into the `Ember.Object` class on top of two methods\n    defined in this mixin: `addObserver` and `removeObserver`. You can use\n    these two methods to add and remove observers yourself if you need to\n    do so at runtime.\n  \n    To add an observer for a property, call:\n  \n    ```javascript\n    object.addObserver('propertyKey', targetObject, targetAction)\n    ```\n  \n    This will call the `targetAction` method on the `targetObject` whenever\n    the value of the `propertyKey` changes.\n  \n    Note that if `propertyKey` is a computed property, the observer will be\n    called when any of the property dependencies are changed, even if the\n    resulting value of the computed property is unchanged. This is necessary\n    because computed properties are not computed until `get` is called.\n  \n    @class Observable\n    @namespace Ember\n    @public\n  */\n  exports.default = _emberMetal.Mixin.create({\n\n    /**\n      Retrieves the value of a property from the object.\n       This method is usually similar to using `object[keyName]` or `object.keyName`,\n      however it supports both computed properties and the unknownProperty\n      handler.\n       Because `get` unifies the syntax for accessing all these kinds\n      of properties, it can make many refactorings easier, such as replacing a\n      simple property with a computed property, or vice versa.\n       ### Computed Properties\n       Computed properties are methods defined with the `property` modifier\n      declared at the end, such as:\n       ```javascript\n      fullName: Ember.computed('firstName', 'lastName', function() {\n        return this.get('firstName') + ' ' + this.get('lastName');\n      })\n      ```\n       When you call `get` on a computed property, the function will be\n      called and the return value will be returned instead of the function\n      itself.\n       ### Unknown Properties\n       Likewise, if you try to call `get` on a property whose value is\n      `undefined`, the `unknownProperty()` method will be called on the object.\n      If this method returns any value other than `undefined`, it will be returned\n      instead. This allows you to implement \"virtual\" properties that are\n      not defined upfront.\n       @method get\n      @param {String} keyName The property to retrieve\n      @return {Object} The property value or undefined.\n      @public\n    */\n    get: function (keyName) {\n      return _emberMetal.get(this, keyName);\n    },\n\n    /**\n      To get the values of multiple properties at once, call `getProperties`\n      with a list of strings or an array:\n       ```javascript\n      record.getProperties('firstName', 'lastName', 'zipCode');\n      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }\n      ```\n       is equivalent to:\n       ```javascript\n      record.getProperties(['firstName', 'lastName', 'zipCode']);\n      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }\n      ```\n       @method getProperties\n      @param {String...|Array} list of keys to get\n      @return {Object}\n      @public\n    */\n    getProperties: function () {\n      for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) {\n        args[_key] = arguments[_key];\n      }\n\n      return _emberMetal.getProperties.apply(undefined, [this].concat(args));\n    },\n\n    /**\n      Sets the provided key or path to the value.\n       ```javascript\n      record.set(\"key\", value);\n      ```\n       This method is generally very similar to calling `object[\"key\"] = value` or\n      `object.key = value`, except that it provides support for computed\n      properties, the `setUnknownProperty()` method and property observers.\n       ### Computed Properties\n       If you try to set a value on a key that has a computed property handler\n      defined (see the `get()` method for an example), then `set()` will call\n      that method, passing both the value and key instead of simply changing\n      the value itself. This is useful for those times when you need to\n      implement a property that is composed of one or more member\n      properties.\n       ### Unknown Properties\n       If you try to set a value on a key that is undefined in the target\n      object, then the `setUnknownProperty()` handler will be called instead. This\n      gives you an opportunity to implement complex \"virtual\" properties that\n      are not predefined on the object. If `setUnknownProperty()` returns\n      undefined, then `set()` will simply set the value on the object.\n       ### Property Observers\n       In addition to changing the property, `set()` will also register a property\n      change with the object. Unless you have placed this call inside of a\n      `beginPropertyChanges()` and `endPropertyChanges(),` any \"local\" observers\n      (i.e. observer methods declared on the same object), will be called\n      immediately.

The `key` is the property that\n      changes. The `value` property is currently reserved and unused. The `rev`\n      is the last property revision of the object when it changed, which you can\n      use to detect if the key value has really changed or not.\n       Usually you will not need the value or revision parameters at\n      the end. In this case, it is common to write observer methods that take\n      only a sender and key value as parameters or, if you aren't interested in\n      any of these values, to write an observer that has no parameters at all.\n       @method addObserver\n      @param {String} key The key to observe\n      @param {Object} target The target object to invoke\n      @param {String|Function} method The method to invoke\n      @public\n    */\n    addObserver: function (key, target, method) {\n      _emberMetal.addObserver(this, key, target, method);\n    },\n\n    /**\n      Remove an observer you have previously registered on this object.

Instantiating a class\n      directly (via `create` or `new`) bypasses the dependency injection\n      system.\n       **Note:** Ember-Data instantiates its models in a unique manner, and consequently\n      injections onto models (or all models) will not work as expected. Injections\n      on models can be enabled by setting `EmberENV.MODEL_FACTORY_INJECTIONS`\n      to `true`.\n       @public\n      @method inject\n      @param  factoryNameOrType {String}\n      @param  property {String}\n      @param  injectionName {String}\n    **/\n    inject: registryAlias('injection')\n  });\n\n  function registryAlias(name) {\n    return function () {\n      var _registry__;\n\n      return (_registry__ = this.__registry__)[name].apply(_registry__, arguments);\n    };\n  }\n\n  function buildFakeRegistryWithDeprecations(instance, typeForMessage) {\n    var fakeRegistry = {};\n    var registryProps = {\n      resolve: 'resolveRegistration',\n      register: 'register',\n      unregister: 'unregister',\n      has: 'hasRegistration',\n      option: 'registerOption',\n      options: 'registerOptions',\n      getOptions: 'registeredOptions',\n      optionsForType: 'registerOptionsForType',\n      getOptionsForType: 'registeredOptionsForType',\n      injection: 'inject'\n    };\n\n    for (var deprecatedProperty in registryProps) {\n      fakeRegistry[deprecatedProperty] = buildFakeRegistryFunction(instance, typeForMessage, deprecatedProperty, registryProps[deprecatedProperty]);\n    }\n\n    return fakeRegistry;\n  }\n\n  function buildFakeRegistryFunction(instance, typeForMessage, deprecatedProperty, nonDeprecatedProperty) {\n    return function () {\n      _emberDebug.deprecate('Using `' + typeForMessage + '.registry.' + deprecatedProperty + '` is deprecated.

However, there are some cases where it is preferable\n  to build up a property's value by combining the superclass' property\n  value with the subclass' value. An example of this in use within Ember\n  is the `classNames` property of `Ember.View`.\n   Here is some sample code showing the difference between a concatenated\n  property and a normal one:\n   ```javascript\n  const Bar = Ember.Object.extend({\n    // Configure which properties to concatenate\n    concatenatedProperties: ['concatenatedProperty'],\n     someNonConcatenatedProperty: ['bar'],\n    concatenatedProperty: ['bar']\n  });\n   const FooBar = Bar.extend({\n    someNonConcatenatedProperty: ['foo'],\n    concatenatedProperty: ['foo']\n  });\n   let fooBar = FooBar.create();\n  fooBar.get('someNonConcatenatedProperty'); // ['foo']\n  fooBar.get('concatenatedProperty'); // ['bar', 'foo']\n  ```\n   This behavior extends to object creation as well. Continuing the\n  above example:\n   ```javascript\n  let fooBar = FooBar.create({\n    someNonConcatenatedProperty: ['baz'],\n    concatenatedProperty: ['baz']\n  })\n  fooBar.get('someNonConcatenatedProperty'); // ['baz']\n  fooBar.get('concatenatedProperty'); // ['bar', 'foo', 'baz']\n  ```\n   Adding a single property that is not an array will just add it in the array:\n   ```javascript\n  let fooBar = FooBar.create({\n    concatenatedProperty: 'baz'\n  })\n  view.get('concatenatedProperty'); // ['bar', 'foo', 'baz']\n  ```\n   Using the `concatenatedProperties` property, we can tell Ember to mix the\n  content of the properties.\n   In `Ember.Component` the `classNames`, `classNameBindings` and\n  `attributeBindings` properties are concatenated.\n   This feature is available for you to use throughout the Ember object model,\n  although typical app developers are likely to use it infrequently.

However, there are some cases where it is preferable\n  to build up a property's value by merging the superclass property value\n  with the subclass property's value. An example of this in use within Ember\n  is the `queryParams` property of routes.\n   Here is some sample code showing the difference between a merged\n  property and a normal one:\n   ```javascript\n  const Bar = Ember.Object.extend({\n    // Configure which properties are to be merged\n    mergedProperties: ['mergedProperty'],\n     someNonMergedProperty: {\n      nonMerged: 'superclass value of nonMerged'\n    },\n    mergedProperty: {\n      page: { replace: false },\n      limit: { replace: true }\n    }\n  });\n   const FooBar = Bar.extend({\n    someNonMergedProperty: {\n      completelyNonMerged: 'subclass value of nonMerged'\n    },\n    mergedProperty: {\n      limit: { replace: false }\n    }\n  });\n   let fooBar = FooBar.create();\n   fooBar.get('someNonMergedProperty');\n  // => { completelyNonMerged: 'subclass value of nonMerged' }\n  //\n  // Note the entire object, including the nonMerged property of\n  // the superclass object, has been replaced\n   fooBar.get('mergedProperty');\n  // => {\n  //   page: {replace: false},\n  //   limit: {replace: false}\n  // }\n  //\n  // Note the page remains from the superclass, and the\n  // `limit` property's value of `false` has been merged from\n  // the subclass.\n  ```\n   This behavior is not available during object `create` calls.

Any instance\n  of the `Person` class will *not* have the `march()` method.\n   You can also pass `Mixin` classes to add additional properties to the subclass.\n   ```javascript\n  const Person = Ember.Object.extend({\n    say(thing) {\n      alert(`${this.get('name')} says: ${thing}`);\n    }\n  });\n   const SingingMixin = Mixin.create({\n    sing(thing){\n      alert(`${this.get('name')} sings: la la la ${thing}`);\n    }\n  });\n   const BroadwayStar = Person.extend(SingingMixin, {\n    dance() {\n      alert(`${this.get('name')} dances: tap tap tap tap `);\n    }\n  });\n  ```\n   The `BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.\n   @method extend\n  @static\n   @param {Mixin} [mixins]* One or more Mixin classes\n  @param {Object} [arguments]* Object containing values to use within the new class\n  @public\n*/\n\n/**\n  Creates an instance of a class.

The\n    primary way of interacting with a promise is through its `then` method, which\n    registers callbacks to receive either a promise’s eventual value or the reason\n    why the promise cannot be fulfilled.\n  \n    Terminology\n    -----------\n  \n    - `promise` is an object or function with a `then` method whose behavior conforms to this specification.\n    - `thenable` is an object or function that defines a `then` method.\n    - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).\n    - `exception` is a value that is thrown using the throw statement.\n    - `reason` is a value that indicates why a promise was rejected.\n    - `settled` the final resting state of a promise, fulfilled or rejected.\n  \n    A promise can be in one of three states: pending, fulfilled, or rejected.\n  \n    Promises that are fulfilled have a fulfillment value and are in the fulfilled\n    state.  Promises that are rejected have a rejection reason and are in the\n    rejected state.  A fulfillment value is never a thenable.\n  \n    Promises can also be said to *resolve* a value.  If this value is also a\n    promise, then the original promise's settled state will match the value's\n    settled state.  So a promise that *resolves* a promise that rejects will\n    itself reject, and a promise that *resolves* a promise that fulfills will\n    itself fulfill.\n  \n  \n    Basic Usage:\n    ------------\n  \n    ```js\n    let promise = new Promise(function(resolve, reject) {\n      // on success\n      resolve(value);\n  \n      // on failure\n      reject(reason);\n    });\n  \n    promise.then(function(value) {\n      // on fulfillment\n    }, function(reason) {\n      // on rejection\n    });\n    ```\n  \n    Advanced Usage:\n    ---------------\n  \n    Promises shine when abstracting away asynchronous interactions such as\n    `XMLHttpRequest`s.\n  \n    ```js\n    function getJSON(url) {\n      return new Promise(function(resolve, reject){\n        let xhr = new XMLHttpRequest();\n  \n        xhr.open('GET', url);\n        xhr.onreadystatechange = handler;\n        xhr.responseType = 'json';\n        xhr.setRequestHeader('Accept', 'application/json');\n        xhr.send();\n  \n        function handler() {\n          if (this.readyState === this.DONE) {\n            if (this.status === 200) {\n              resolve(this.response);\n            } else {\n              reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));\n            }\n          }\n        };\n      });\n    }\n  \n    getJSON('/posts.json').then(function(json) {\n      // on fulfillment\n    }, function(reason) {\n      // on rejection\n    });\n    ```\n  \n    Unlike callbacks, promises are great composable primitives.\n  \n    ```js\n    Promise.all([\n      getJSON('/posts'),\n      getJSON('/comments')\n    ]).then(function(values){\n      values[0] // => postsJSON\n      values[1] // => commentsJSON\n  \n      return values;\n    });\n    ```\n  \n    @class RSVP.Promise\n    @param {function} resolver\n    @param {String} label optional string for labeling the promise.\n    Useful for tooling.\n    @constructor\n  */\n  function Promise(resolver, label) {\n    this._id = counter++;\n    this._label = label;\n    this._state = undefined;\n    this._result = undefined;\n    this._subscribers = [];\n\n    config.instrument && instrument('created', this);\n\n    if (noop !== resolver) {\n      typeof resolver !== 'function' && needsResolver();\n      this instanceof Promise ? initializePromise(this, resolver) : needsNew();\n    }\n  }\n\n  Promise.cast = resolve$1; // deprecated\n  Promise.all = all;\n  Promise.race = race;\n  Promise.resolve = resolve$1;\n  Promise.reject = reject$1;\n\n  Promise.prototype = {\n    constructor: Promise,\n\n    _guidKey: guidKey,\n\n    _onError: function (reason) {\n      var promise = this;\n      config.after(function () {\n        if (promise._onError) {\n          config['trigger']('error', reason, promise._label);\n        }\n      });\n    },\n\n    /**\n      The primary way of interacting with a promise is through its `then` method,\n      which registers callbacks to receive either a promise's eventual value or the\n      reason why the promise cannot be fulfilled.\n    \n      ```js\n      findUser().then(function(user){\n        // user is available\n      }, function(reason){\n        // user is unavailable, and you are given the reason why\n      });\n      ```\n    \n      Chaining\n      --------\n    \n      The return value of `then` is itself a promise.  This second, 'downstream'\n      promise is resolved with the return value of the first promise's fulfillment\n      or rejection handler, or rejected if the handler throws an exception.\n    \n      ```js\n      findUser().then(function (user) {\n        return user.name;\n      }, function (reason) {\n        return 'default name';\n      }).then(function (userName) {\n        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it\n        // will be `'default name'`\n      });\n    \n      findUser().then(function (user) {\n        throw new Error('Found user, but still unhappy');\n      }, function (reason) {\n        throw new Error('`findUser` rejected and we\\'re unhappy');\n      }).then(function (value) {\n        // never reached\n      }, function (reason) {\n        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.\n        // If `findUser` rejected, `reason` will be '`findUser` rejected and we\\'re unhappy'.\n      });\n      ```\n      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n    \n      ```js\n      findUser().then(function (user) {\n        throw new PedagogicalException('Upstream error');\n      }).then(function (value) {\n        // never reached\n      }).then(function (value) {\n        // never reached\n      }, function (reason) {\n        // The `PedgagocialException` is propagated all the way down to here\n      });\n      ```\n    \n      Assimilation\n      ------------\n    \n      Sometimes the value you want to propagate to a downstream promise can only be\n      retrieved asynchronously. This can be achieved by returning a promise in the\n      fulfillment or rejection handler. The downstream promise will then be pending\n      until the returned promise is settled. This is called *assimilation*.\n    \n      ```js\n      findUser().then(function (user) {\n        return findCommentsByAuthor(user);\n      }).then(function (comments) {\n        // The user's comments are now available\n      });\n      ```\n    \n      If the assimliated promise rejects, then the downstream promise will also reject.\n    \n      ```js\n      findUser().then(function (user) {\n        return findCommentsByAuthor(user);\n      }).then(function (comments) {\n        // If `findCommentsByAuthor` fulfills, we'll have the value here\n      }, function (reason) {\n        // If `findCommentsByAuthor` rejects, we'll have the reason here\n      });\n      ```\n    \n      Simple Example\n      --------------\n    \n      Synchronous Example\n    \n      ```javascript\n      let result;\n    \n      try {\n        result = findResult();\n        // success\n      } catch(reason) {\n        // failure\n      }\n      ```\n    \n      Errback Example\n    \n      ```js\n      findResult(function(result, err){\n        if (err) {\n          // failure\n        } else {\n          // success\n        }\n      });\n      ```\n    \n      Promise Example;\n    \n      ```javascript\n      findResult().then(function(result){\n        // success\n      }, function(reason){\n        // failure\n      });\n      ```\n    \n      Advanced Example\n      --------------\n    \n      Synchronous Example\n    \n      ```javascript\n      let author, books;\n    \n      try {\n        author = findAuthor();\n        books  = findBooksByAuthor(author);\n        // success\n      } catch(reason) {\n        // failure\n      }\n      ```\n    \n      Errback Example\n    \n      ```js\n    \n      function foundBooks(books) {\n    \n      }\n    \n      function failure(reason) {\n    \n      }\n    \n      findAuthor(function(author, err){\n        if (err) {\n          failure(err);\n          // failure\n        } else {\n          try {\n            findBoooksByAuthor(author, function(books, err) {\n              if (err) {\n                failure(err);\n              } else {\n                try {\n                  foundBooks(books);\n                } catch(reason) {\n                  failure(reason);\n                }\n              }\n            });\n          } catch(error) {\n            failure(err);\n          }\n          // success\n        }\n      });\n      ```\n    \n      Promise Example;\n    \n      ```javascript\n      findAuthor().\n        then(findBooksByAuthor).\n        then(function(books){\n          // found books\n      }).catch(function(reason){\n        // something went wrong\n      });\n      ```\n    \n      @method then\n      @param {Function} onFulfillment\n      @param {Function} onRejection\n      @param {String} label optional string for labeling the promise.\n      Useful for tooling.\n      @return {Promise}\n    */\n    then: then,\n\n    /**\n      `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same\n      as the catch block of a try/catch statement.\n    \n      ```js\n      function findAuthor(){\n        throw new Error('couldn\\'t find that author');\n      }\n    \n      // synchronous\n      try {\n        findAuthor();\n      } catch(reason) {\n        // something went wrong\n      }\n    \n      // async with promises\n      findAuthor().catch(function(reason){\n        // something went wrong\n      });\n      ```\n    \n      @method catch\n      @param {Function} onRejection\n      @param {String} label optional string for labeling the promise.\n      Useful for tooling.\n      @return {Promise}\n    */\n    catch: function (onRejection, label) {\n      return this.then(undefined, onRejection, label);\n    },\n\n    /**\n      `finally` will be invoked regardless of the promise's fate just as native\n      try/catch/finally behaves\n    \n      Synchronous example:\n    \n      ```js\n      findAuthor() {\n        if (Math.random() > 0.5) {\n          throw new Error();\n        }\n        return new Author();\n      }\n    \n      try {\n        return findAuthor();

You can use `denodeify` in Node.js or the\n    browser when you'd prefer to use promises over using callbacks. For example,\n    `denodeify` transforms the following:\n  \n    ```javascript\n    let fs = require('fs');\n  \n    fs.readFile('myfile.txt', function(err, data){\n      if (err) return handleError(err);\n      handleData(data);\n    });\n    ```\n  \n    into:\n  \n    ```javascript\n    let fs = require('fs');\n    let readFile = RSVP.denodeify(fs.readFile);\n  \n    readFile('myfile.txt').then(handleData, handleError);\n    ```\n  \n    If the node function has multiple success parameters, then `denodeify`\n    just returns the first one:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request'));\n  \n    request('http://example.com').then(function(res) {\n      // ...\n    });\n    ```\n  \n    However, if you need all success parameters, setting `denodeify`'s\n    second parameter to `true` causes it to return all success parameters\n    as an array:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request'), true);\n  \n    request('http://example.com').then(function(result) {\n      // result[0] -> res\n      // result[1] -> body\n    });\n    ```\n  \n    Or if you pass it an array with names it returns the parameters as a hash:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request'), ['res', 'body']);\n  \n    request('http://example.com').then(function(result) {\n      // result.res\n      // result.body\n    });\n    ```\n  \n    Sometimes you need to retain the `this`:\n  \n    ```javascript\n    let app = require('express')();\n    let render = RSVP.denodeify(app.render.bind(app));\n    ```\n  \n    The denodified function inherits from the original function. It works in all\n    environments, except IE 10 and below. Consequently all properties of the original\n    function are available to you. However, any properties you change on the\n    denodeified function won't be changed on the original function. Example:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request')),\n        cookieJar = request.jar(); // <- Inheritance is used here\n  \n    request('http://example.com', {jar: cookieJar}).then(function(res) {\n      // cookieJar.cookies holds now the cookies returned by example.com\n    });\n    ```\n  \n    Using `denodeify` makes it easier to compose asynchronous operations instead\n    of using callbacks. For example, instead of:\n  \n    ```javascript\n    let fs = require('fs');\n  \n    fs.readFile('myfile.txt', function(err, data){\n      if (err) { ... } // Handle error\n      fs.writeFile('myfile2.txt', data, function(err){\n        if (err) { ... } // Handle error\n        console.log('done')\n      });\n    });\n    ```\n  \n    you can chain the operations together using `then` from the returned promise:\n  \n    ```javascript\n    let fs = require('fs');\n    let readFile = RSVP.denodeify(fs.readFile);\n    let writeFile = RSVP.denodeify(fs.writeFile);\n  \n    readFile('myfile.txt').then(function(data){\n      return writeFile('myfile2.txt', data);\n    }).then(function(){\n      console.log('done')\n    }).catch(function(error){\n      // Handle error\n    });\n    ```\n  \n    @method denodeify\n    @static\n    @for RSVP\n    @param {Function} nodeFunc a 'node-style' function that takes a callback as\n    its last argument.
