    "content": "# LoLa Programming Language\n\n![LoLa Logo](design/logo.png)\n\nLoLa is a small programming language meant to be embedded into games to be programmed by the players. The compiler and runtime are implemented in Zig and C++.\n\n## Short Example\n```js\nvar list = [ \"Hello\", \"World\" ];\nfor(text in list) {\n\tPrint(text);\n}\n```\n\nYou can find more examples in the [examples](examples/lola) folder.\n\n## Why LoLa when there is *X*?\nLoLa isn't meant to be your next best day-to-day scripting language. Its design is focused on embedding the language in environments where the users want/need/should write some small scripts like games or scriptable applications. In most script languages, you as a script host don't have control over the execution time of the scripts you're executing. LoLa protects you against programming errors like endless loops and such:\n\n### Controlled Execution Environment\n\nEvery script invocation gets a limit of instructions it might execute. When either this limit is reached or the script yields for other reasons (asynchronous functions), the execution is returned to the host.\n\nThis means, you can execute the following script \"in parallel\" to your application main loop without blocking your application *and* without requiring complex multithreading setups:\n\n```js\nvar timer = 0;\nwhile(true) {\n\tPrint(\"Script running for \", timer, \" seconds.\");\n\ttimer += 1;\n\tSleep(1.0);\n}\n```\n\n### Native Asynchronous Design\n\nLoLa features both synchronous and asynchronous host functions. Synchronous host function calls are short-lived and will be executed in-place. Asynchronous functions, in contrast, will be executed multiple times until they yield a value. When they don't yield a value, control will be returned to the script host.\n\nThis script will not exhaust the instruction limit, but will only increment the counter, then return control back to the host:\n```js\nvar counter = 0;\nwhile(true) {\n\tcounter += 1;\n\tYield();\n}\n```\n\nThis behaviour can be utilized to wait for certain events in the host environment, for example to react to key presses, a script could look like this:\n```js\nwhile(true) {\n\tvar input = WaitForKey();\n\tif(input == \" \") {\n\t\tPrint(\"Space was pressed!\");\n\t}\n}\n```\n\n*Note that the current implementation is not thread-safe, but requires to use the limited execution for running scripts in parallel.*\n\n### Native \"RPC\" Design\n\nLoLa also allows executing multiple scripts on the same *environment*, meaning that you can easily create cross-script communications:\n\n```js\n// script a:\nvar buffer;\nfunction Set(val) { buffer = val; }\nfunction Get() { return val; }\n\n// script b:\n// GetBuffer() returns a object referencing a environment for \"script a\"\nvar buffer = GetBuffer();\nbuffer.Set(\"Hello, World!\");\n\n// script c:\n// GetBuffer() returns a object referencing a environment for \"script a\"\nvar buffer = GetBuffer(); \nPrint(\"Buffer contains: \", buffer.Get());\n```\n\nWith a fitting network stack and library, this can even be utilized cross-computer.\n\nThis example implements a small chat client and server that could work with LoLa RPC capabilities:\n```js\n// Chat client implementation:\nvar server = Connect(\"lola-rpc://random-projects.net/chat\");\nif(server == void) {\n\tPrint(\"Could not connect to chat server!\");\n\tExit(1);\n}\n\nwhile(true) {\n\tvar list = server.GetMessages(GetUser());\n\tfor(msg in list) {\n\t\tPrint(\"< \", msg);\n\t}\n\t\n\tPrint(\"> \");\n\tvar msg = ReadLine();\n\tif(msg == void)\n\t\tbreak;\n\tif(msg == \"\")\n\t\tcontinue;\n\tserver.Send(GetUser(), msg);\n}\n```\n\n```js\n// Chat server implementation\nvar messages = CreateDictionary();\n\nfunction Send(user, msg)\n{\n\tfor(other in messages.GetKeys())\n\t{\n\t\tif(other != user) {\n\t\t\tvar log = messages.Get(other);\n\t\t\tif(log != void) {\n\t\t\t\tlog = log ++ [ user + \": \" + msg ];\n\t\t\t} else {\n\t\t\t\tlog = [];\n\t\t\t}\n\t\t\tmessages.Set(other, log);\n\t\t}\n\t}\n}\n\nfunction GetMessages(user)\n{\n\tvar log = messages.Get(user);\n\tif(log != void) {\n\t\tmessages.Set(user, []);\n\t\treturn log;\n\t} else {\n\t\treturn [];\n\t}\n}\n```\n\n### Serializable State\n\nAs LoLa has no reference semantics except for objects, it is easy to understand and learn. It is also simple in its implementation and does not require a complex garbage collector or advanced programming knowledge. Each LoLa value can be serialized/deserialized into a sequence of bytes (only exception are object handles, those require some special attention), so saving the current state of a environment/vm to disk and loading it at a later point is a first-class supported use case.\n\nThis is especially useful for games where it is favourable to save your script state into a save game as well without having any drawbacks.\n\n### Simple Error Handling\n\nLoLa provides little to no in-language error handling, as it's not designed to be robust against user programming errors. Each error is passed to the host as a panic, so it can show the user that there was an error (like `OutOfMemory` or `TypeMismatch`).\n\nIn-language error handling is based on the dynamic typing: Functions that allow in-language error handling just return `void` instead of a actual return value or `true`/`false` for *success* or *failure*. \n\nThis allows simple error checking like this:\n```js\nvar string = ReadFile(\"demo.data\");\nif(string != void) {\n\tPrint(\"File contained \", string);\n}\n```\n\nThis design decision was made with the idea in mind that most LoLa programmers won't write the next best security critical software, but just do a quick hack in game to reach their next item unlock.\n\n### Smart compiler\n\nAs LoLa isn't the most complex language, the compiler can support the programmer. Even though the language has fully dynamic typing, the compiler can do some type checking at compile time already:\n\n```js\n// warning: Possible type mismatch detected: Expected number|string|array, found boolean\nif(a < true) { }\n```\n\nRight now, this is only used for validating expressions, but it is planned to extend this behaviour to annotate variables as well, so even more type errors can be found during compile time.\n\nNote that this is a fairly new feature, it does not catch all your type mismatches, but can prevent the obvious ones.\n\n## Starting Points\n\nTo get familiar with LoLa, you can check out these starting points:\n\n- [Documentation](documentation/README.md)\n- [LoLa Examples](examples/lola/README.md)\n- [Script Host Examples](examples/host)\n\nWhen you want to contribute to the compiler, check out the following documents:\n\n- [Source Code](src/)\n- [Bison Grammar](src/library/compiler/grammar.yy)\n- [Flex Tokenizer](src/library/compiler/yy.l)\n- [Issue List](https://github.com/MasterQ32/LoLa/issues)\n\n## Visual Studio Code Extension\nIf you want syntax highlighting in VSCode, you can install the [`lola-vscode`](https://github.com/MasterQ32/lola-vscode) extension.\n\nRight now, it's not published in the gallery, so to install the extension, you have to sideload it. [See the VSCode documentation for this](https://vscode-docs.readthedocs.io/en/stable/extensions/install-extension/).\n\n## Building\n\n### Continous Integration\n\n[![Build](https://github.com/MasterQ32/LoLa/actions/workflows/build.yml/badge.svg)](https://github.com/MasterQ32/LoLa/actions/workflows/build.yml) [![Render Website](https://github.com/MasterQ32/LoLa/actions/workflows/website.yml/badge.svg)](https://github.com/MasterQ32/LoLa/actions/workflows/website.yml)\n\n### Requirements\n\n- The [Zig Compiler](https://ziglang.org/) (Version 0.15.2 or compatible)\n\n### Building\n\n```sh\nzig build\n./zig-out/bin/lola\n```\n\n### Examples\n\nTo compile the host examples, you can use `zig build examples` to build all provided examples. These will be available in `./zig-out/bin` then.\n\n### Running the test suite\n\nWhen you change things in the compiler or VM implementation, run the test suite:\n\n```sh\nzig build test\n```\n\nThis will execute all zig tests, and also runs a set of predefined tests within the [`src/test/`](src/test/) folder. These tests will verify that the compiler and language runtime behave correctly.\n\n### Building the website\n\nThe website generator is gated behind `-Denable-website` which removes a lot of dependencies for people not wanting to render a new version of the website.\nIf you still want to update/change the website or documentation, use the following command:\n\n```sh\nzig build -Denable-website \"-Dversion=$(git describe --tags || git rev-parse --short HEAD)\" website\n```\n\nIt will depend on [koino](https://github.com/kivikakk/koino), which is included as a git submodule. Adding new pages to the documentation is done by modifying the `menu_items` array in `src/tools/render-md-page.zig`.\n"

    "content": "# The LoLa Programming Language\n\n## Introduction\n\nLoLa is a small programming language developed to be embedded in games. It's not meant as a scripting language to create games with but as language to be **programmed in the game by the player**.\n\nThe design goals of the language are:\n\n- Easy to learn\n- Small set of language features\n- No complex features, there are only value types\n- Exhaustible execution – Limit how long a certain script run at most in a single script call\n\n## Hello World\n\n```js\nPrint(\"Hello, World!\");\n```\n\nAs you can see, the *Hello World*-Program is quite short and expressive. The language itself uses a C-like syntax with semicolons at the end of a statement.\n\nMore [Examples](#Examples) can be found at the end of the document.\n\n## Comments\n\nLoLa provides only single-line comments:\n\n```js\n// This is a comment\n\nPrint(\"Hello\"); // this is a statement, followed by a comment\n```\n\nEverything that is in a comment is ignored by the compiler. A comment is introduced by a double-slash (`//`) and is ended by a line feed character or the end of the file.\n\n## Types\n\nThe language provides a small set of types data can have:\n\n| Type      | Description                                                  |\n| --------- | ------------------------------------------------------------ |\n| `void`    | The `void` type can only have a single value (which is also `void`) and indicates the absence of a value. Functions that do not return something will return this. |\n| `boolean` | A truth value, which is either `true` or `false`. This type is the result of comparisons and can be passed to conditionals. It is also the input to the [boolean algebra](https://en.wikipedia.org/wiki/Boolean_algebra) operators. |\n| `number`  | A [IEEE-754 binary64](https://en.wikipedia.org/wiki/Double-precision_floating-point_format) encoded real number. This is the basic type for all algebraic operations. |\n| `string`  | A [string](https://en.wikipedia.org/wiki/String_(computer_science)) in LoLa is a sequence of bytes, usually encodes text as [ASCII](https://en.wikipedia.org/wiki/ASCII) or [UTF-8](https://en.wikipedia.org/wiki/UTF-8). |\n| `object`  | An object is a thing that has an interface with callable methods. |\n| `array`   | An array is a sequence of arbitrary values.                  |\n| `struct`  | A struct is a collection of named fields, each holding an arbitrary value. |\n\n## Literals\n\nLiterals provide a way to create a primitive value in the language. All of the types except `object` have a literal syntax:\n\n| Type      | Examples                                                               |\n| --------- | ---------------------------------------------------------------------- |\n| `void`    | `void` (no other values are allowed)                                   |\n| `boolean` | `true`, `false` (no other values are allowed)                          |\n| `number`  | `0`, `1`, `0.0`, `10.0`, `0.25`, `13.37`, …                            |\n| `string`  | `\"Hello, World!\"`, `\"\"`, `\"One\\nTwo\\nThree\"`                           |\n| `array`   | `[]`, `[1,2,3,4,5]`, `[true, false, void]`                             |\n| `struct`  | `[.x=0, .y=0]`, `[.name=\"LoLa\", .version=1]`, `[.flag=true, .val=42]` |\n\nLoLa also supports character literals. Character literals have the type `number` and will be equivalent to their unicode codepoint and might be written literally (`ö`) or with the same rules as string escapes (`\\xF3`):\n\n```js\n0x20    == ' '\n0x07    == '\\a'\n0x1F4A9 == '💩'\n0xF3    == '\\xF3'\n0x1F4A9 == '\\xf0\\x9f\\x92\\xa9'\n```\n\nAs LoLa doesn't enforce utf-8 encoding, all single-byte literals will be copied verbatim, allowing support for any 8-bit encoding. All literals that take up more than a single byte will be assumed utf-8 encoded.\n\n### String Escape Sequence\n\nAs strings are contained in double quotes and don't allow to contain a line feed, one needs the possibility to escape those characters. For this, LoLa provides two ways to include escaped and non-printable characters in a string:\n\n- Use a hexadecimal escape (`\\x63`)\n- Use one of the predefined escape shorthands (`\\r`, `\\n`)\n\nThe hexadecimal escape allows the programmer to embed any byte value into the string. It is introduced by the escape character `\\`, followed by a small `x`, then a two-digit hexadecimal number. The number is then converted into a byte value and inserted into the string.\n\nThe predefined escape codes provide often-required whitespace and control characters without the need to remember their exact value:\n\n| Shorthand | ASCII Value | Name            |\n| --------- | ----------- | --------------- |\n| `\\a`      | 7           | Alert / Bell    |\n| `\\b`      | 8           | Backspace       |\n| `\\t`      | 9           | Horizontal Tab  |\n| `\\n`      | 10          | Line Feed       |\n| `\\r`      | 13          | Carriage Return |\n| `\\e`      | 27          | Escape          |\n| `\\\"`      | 34          | Double Quotes   |\n| `\\'`      | 39          | Single Quote    |\n\n## Variables\n\nVariables provide a way to store something beyond the context of a single computation.\n\n```js\nvar x;      // Uninitialized, global variable\nvar y = 10; // Initialized global variable\n\n{\n  var z;     // Unitialized local variable\n  var w = 0; // Initialized local variable\n}\n```\n\nThere are three kind of variables in LoLa:\n\n- Global Variables\n- Local Variables\n\nGlobal variables are accessible from any scope and are stored in the execution environment. **If a global variable has no initializer, it's value is preserved over multiple calls of the script.**\n\nLocal variables could also be called temporary variables as they are only alive for a short time. A local variables is any variable declared in brackets, so explicit declared locals, loop variables and function parameters.\n\nAll variables are dynamically typed and may change the type of the stored value on assignment.\n\n### Shadowing\n\nLoLa allows shadowing of variable names. This means, that you can have a variable with the same name as a previously declared variable. The previously declared variable will be hidden (shadowed) by the newly declared variable for the scope of the shadowing variable.\n\n## Operators\n\nLoLa provides several operators that execute arithmetic, logic or comparison operations.\n\n### Table of Operators\n\n| Operator | Applies to                  | Description                               | Example                                                      |\n| -------- | --------------------------- | ----------------------------------------- | ------------------------------------------------------------ |\n| `a + b` <br /> `a += b` | `string`, `number`, `array` | Adds numbers, concats strings and arrays. | `3 + 2 == 5`, `\"a\" + \"b\" == \"ab\"`, `[ 1, 2 ] + [ 3 ] == [ 1, 2, 3 ]` |\n| `a - b` <br />`a -= b` | `number` |Subtraction|`5 - 2 == 3`|\n| `-a`  | `number` | Negation |`-(4) == -4`|\n| `a * b` <br />`a *= b` | `number` |Multiplication|`5 * 2 == 10`|\n| `a / b `<br />`a /= b` | `number` |Division|`10 / 5 == 2`|\n| `a % b` <br />`a %= b` | `number` |Remainder Division|`10 % 4 == 2`|\n| `a and b` | `boolean` |Boolean AND|`true and false == false`|\n| `a or b` | `boolean` |Boolean OR|`true or false == true`|\n| `not a` | `boolean` |Boolean NOT|`not false == true`|\n| `a == b` | *all* |Equality test|`(3 == 3) == true`|\n| `a != b` | *all* |Inequality test|`(3 != 2) == true`|\n| `a >= b` | `number` |Greater-or-equal test|`(3 >= 2) == true`|\n| `a <= b` | `number` |Less-or-equal test|`(3 <= 2) == false`|\n| `a > b` | `number` |Greater-than test|`(3 > 2) == true`|\n| `a < b` | `number` |Less-than test|`(3 < 2) == false`|\n| `a[i]` | `array`, `string` | Array index, string index | `([1,2,3])[1] == 2` |\n| `a.field` | `struct` | Field access | `([.x=1, .y=2]).x == 1` |\n\n### Operator Precedence \n\nOperator precedence in the list low to high. A higher precedence means that these operators *bind* more to the variables and will be applied first.\n\n#### Binary\n\n- `and`, `or`\n- `==`, `!=`, `>=`, `<=`, `>`, `<`\n- `+`, `-`\n- `*`, `/`, `%`\n\n#### Unary\n\n- `not`, `-`\n- `a[i]`\n- `a.field`\n\n## Control Flow Structures\n\nLoLa provides a small set of control flow structures that are simple to use and are widespread in a lot of programming languages.\n\n### Blocks\n\n```js\n{ // Blocks are always introduced by a curly bracket\n  var x; // local to this block\n  // here is the block content\n} // and are closed by a curly bracket\n\n// x is not valid here anymore!\n```\n\nBlocks are a convenient way of introducing structure into the code. Each block has its own set of local variables, but can access the local variables of its parent as well. Each control structure in LoLa is followed by a block, but blocks can also be freestanding as in the example above.\n\n### Assignments\n\nAssignments in LoLa are statements that return no value. This is different from other programming languages like C that allow nesting assignments into expressions (~~`a + (b = c)`~~).\n\n```js\na = b; // simple assignment, copy the value from b into a.\n```\n\nAn assignment will always copy the value that is assigned. It will not create equality of the two names:\n\n```js\na = 1;\nb = a;\na = 2;\nPrint(a, b); // Will print \"2, 1\" as b has not been changed\n```\n\nYou can always assign an item of array:\n\n```js\na[i] = c; // indexed assignment: copy the value of c into the i'th index of the array a.\n```\n\nThis allows mutating the contents of the array. The same rules as for a normal variable assignment apply here.\n\nYou can also assign a field of a struct:\n\n```js\na.field = c; // field assignment: copy the value of c into the field named 'field' of the struct a.\n```\n\nAssigning a field that does not exist in the struct will cause a panic.\n\n### `if`-Conditional\n\nThe conditional `if` statement provides a simple way to do things depending on a condition:\n\n```js\nif(a > 5) {\n  // This code is executed only when a > 5.\n}\n```\n\nThe code in the curly brackets is only executed when the condition in the round brackets is `true`. The condition must always be a `boolean` value.\n\nIf the code should do an *either-or* semantic, you can add an else block:\n\n```js\nif(a > 5) {\n  // This code is executed only when a > 5.\n}\nelse {\n  // This code is executed when a <= 5. \n}\n```\n\nThe `else` part is optional.\n\n`if` also provides a short-hand version if only a single statement is conditional:\n\n```js\nif(condition)\n  Statement(); // Function call, control flow or assignment\n \nif(condition)\n  Statement();\nelse\n  Statement();\n```\n\n\n\n### `while`-Loop\n\nIf a piece of code should repeat itself, a loop structure is helpful:\n\n```js\nwhile(a > 5) {\n  // this code repeats as long as a > 5.\n}\n```\n\nThe `while` loop will check the condition in the round brackets. If the condition is `true`, the code in the curly brackets will be executed. After that, the condition will be checked again and the process starts again.\n\n### `for`-Loop\n\nIterating over an array is such a common task that LoLa provides a built-in loop for that:\n\n```js\nfor(x in data) {\n  // For each loop iteration, x will contain a value from data\n}\n```\n\nThe syntax for the loop is `for(var in data) { … }` where `var` is a new local variable, and `data` is an array value.\n\nThe loop will execute one time for each item in `data`, filling `var` with the current item. The items are processed in order.\n\n### Function Calls\n\n```js\nPrint(\"Hello, World!\"); // Calls the function Print with one arg.\nx = GetSomething(); // stores the return value of GetSomething()\n```\n\nFunction calls will execute a sub-program that may return a value to their caller. A function call may take zero or more arguments, but will always return a value. If the return value is not stored, it will be discarded.\n\n### Method Calls\n\nMethods calls are similar to function calls, but require an `object` value to be executed:\n\n```js\nvar obj = …; // We require a variable of type object\n\nobj.Print(\"Hello, World!\"); // Call the method Print on obj.\n```\n\nThe `Print` in this case is not a usual function but a method. Methods are defined on objects and pass the object to the method as well.\n\nThis allows the script runtime to provide the user with more complex data structures or interfaces that are implemented via objects instead of free functions.\n\nObjects can also represent resources like [sockets](https://en.wikipedia.org/wiki/Network_socket) or [key-value-stores](https://en.wikipedia.org/wiki/Key-value_database) that are available to the user.\n\n### `return`\n\n`return` will stop the execution of the current sub-program and will return control to the caller.\n\n```js\nreturn; // Stop execution now, return void\nreturn true; // Stop execution now and return true\n```\n\n`return` may take an optional value that will be returned as a result of the sub-program.\n\nReturning a value from global execution environment is not allowed, returning a value to the script host should be done with a function provided by the host.\n\n### `break`\n\n`break` will cancel the current loop execution. This means that it will continue execution after the loop-block:\n\n```js\nvar i = 0;\nvar j = 0;\nwhile(true)\n{\n  i += 1;\n  Print(\"i = \", i);\n  if(i > 5)\n    break; // this will jump to after the while-loop \n  j += 1;\n}\n// <= break will continue execution here\nPrint(i, j); // Will print 6, 5\n```\n\nThe same goes for `for` loops:\n\n```js\nfor(x in [ 1, 2, 3, 4 ])\n{\n  if(x > 2)\n    break; // this will jump to after the for-loop \n}\n// <= break will continue execution here\n```\n\n### `continue`\n\n`continue` is the counterpart to `break`: It will continue with the next loop iteration instead of completing the current one. This can be used to skip a whole bunch of code:\n\n```js\nvar a = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ];\nvar skipped = 0;\nfor(x in a)\n{\n  // continue will continue from here\n  if(x < 3) {\n    skipped += 1;\n    continue; // jumps to the start of the loop with the next var\n  }\n  Print(x);\n}\nPrint(\"Skipped \", skipped, \" elements!\");\n```\n\nThe same goes for `while` loops as well:\n\n```js\nvar i = 0;\nwhile(i < 10)\n{\n  // continue will continue from here\n  i += 1;\n  if(i < 4)\n    continue; // jumps to the start of the loop\n  Print(i);\n}\n```\n\n\n\n## Functions\n\nFunctions allows the user to declare custom sub-programs in the script:\n\n```js\nfunction AddFive(a) {\n  return a + 5;\n}\n\nfunction Compare(a, b) {\n  if(a > b) {\n    return \"larger\";\n  }\n  else if(a < b) {\n    return \"smaller\";\n  } else {\n    return \"equal\";\n  }\n}\n```\n\nFunctions have their own scope, and may `return` a value to their caller. \n\n## Top Level Code\n\nSimilar to other scripting languages, LoLa allows not only top-level declarations, but also top-level code. This means there is no `main` function that is called when starting execution, but the top-level code will be run instead.\n\n```js\n// This is not a snippet, but a valid file!\nSayHelloTo(\"me\");\n\nfunction SayHelloTo(name)\n{\n  Print(\"Hello, \" + name + \"!\");\n}\n```\n\nAs you can see, the order of declaration is not relevant in LoLa. Functions may be called from top-level before or after declaration.\n\n## Error Handling\n\nThe LoLa language has not a very sophisticated error handling concept. If something goes wrong, the runtime will just panic and return execution to the host system with the position where the panic happened as well as some basic info about what failed.\n\nPossible panics are:\n\n- `OutOfMemory` (the host ran out of memory while executing the code)\n- `TypeMismatch` (an operation or function expected one type, but got another)\n- `IndexOutOfBounds` (an array was indexed outside the boundaries of the array)\n- `InvalidArgs` (a wrong number of arguments was passed to a function)\n- `OutOfRange` (a numeric value wasn't in the allowed range)\n\nA panic may be caused by the LoLa virtual machine or any library functions.\n\n## Objects\n\nObjects in LoLa are opaque handles except for their methods. Users cannot declare or create objects without the help of the script host. Object handles are usually valid as long as the LoLa script has access to that handle, but the script host might destroy objects actively as well.\n\nObject handles can be considered a reference type as you don't get a copy of the object when you pass a handle around. This type would be the only exception to LoLas design of *value types only*.\n\n## Structs\n\nStructs are value types that hold a fixed set of named fields, each of which can hold an arbitrary value. They are created with a struct literal:\n\n```js\nvar point = [.x = 1, .y = 2];\n```\n\nFields are accessed and assigned using the `.field` notation:\n\n```js\nPrint(point.x);   // prints 1\npoint.y = 10;\nPrint(point.y);   // prints 10\n```\n\nAccessing or assigning a field that does not exist in the struct will cause a panic.\n\nBecause structs are value types, assigning a struct variable copies the entire struct:\n\n```js\nvar a = [.x = 1];\nvar b = a;\nb.x = 99;\nPrint(a.x); // still 1 — a was not affected\n```\n\n## LoLa File Types\n\nThe following list contains LoLa-related file types \n\n- LoLa Code (`*.lola`)\n  These files contain actual LoLa source code and can be compiled into modules.\n- [LoLa Modules](Modules.md) (`*.lola.lm`)\n  These files contain compiled LoLa byte code and can be executed by a [LoLa VM](IR.md).\n\n## Frequently Asked Questions\n\nThis section tries to answer questions that are commonly asked.\n\n### Why does the language not allow user-defined objects?\n\nThe design decision of LoLa was to be a simple as possible without losing too much features. User-defined objects would make the language way more complex and harder to reason about code. As the focus group of the language is mostly programmer novices, this complexity was left out and passed to the script host.\n\nIt is still possible to create user-defined objects and classes though: The script host might implement a function `MakeObject(str)` which compiles a LoLa source and returns the compiled script as a object, evaluating the top-level code as some kind of constructor and exporting all functions as methods to that object.\n\n## List of Keywords\n\n- `and`\n- `break`\n- `const`\n- `continue`\n- `else`\n- `for`\n- `function`\n- `if`\n- `in`\n- `not`\n- `or`\n- `return`\n- `var`\n- `while`\n\n## Wording\n\nThe following chapter explains some of the words used in this document with concrete focus on the meaning inside LoLa.\n\n### Statement\n\nA statement is something that can be written as a line of code or execution unit.\n\nThe following constructs count as statements:\n\n- Conditionals (`if`)\n- Loops (`while`, `for`)\n- Everything with a semicolon at the end (`a = …;`, `a[i] = …;`, `Print(\"Hi!\");`)\n\n### Expression\n\nAn expression is something that yields a value that can be used in another expression or can be assigned to a value.\n\nExamples for expressions are:\n\n- `1`\n- `\"Hello\"`\n- `expr + expr`\n- `SumOf(10, 20)`\n- …\n\nLoLa does not allow lone statements except for function and method calls. These are special in a way that they may discard their value. The resulting value of all other expressions may not be discarded.\n\n### Block\n\nAny piece of code between `{` and `}`. The block con\n\n## Examples\n\nThe following section will contain small examples on how to use the language.\n\n### Sum the values of an array\n\n```js\nvar a = [ 1, 2, 3 ];\nvar sum = 0;\nfor(v in a) {\n  sum += a;\n}\nPrint(\"Sum = \", sum);\n```\n\n### Bubble Sort\n\n```js\nfunction BubbleSort(arr)\n{\n  var len = Length(arr);\n\n  var n = len;\n  while(n > 1) {\n\n    var i = 0;\n    while(i < n - 1) {\n      if (arr[i] > arr[i+1]) {\n        var tmp = arr[i];\n        arr[i] = arr[i+1];\n        arr[i+1] = tmp;\n      }\n\n      i += 1;\n    }\n    n -= 1;\n  }\n\n  return arr;\n}\n\nPrint(BubbleSort([ 7, 8, 9, 3, 2, 1 ]));\n```\n\n### Reversing an array\n\n```js\n// Reverse an array\nfunction RevertArray(arr)\n{\n  var i = 0;\n  var l = Length(arr);\n  while(i < l/2) {\n    var tmp = arr[i];\n    arr[i] = arr[l - i - 1];\n    arr[l - i - 1] = tmp;\n    i += 1;\n  }\n  return arr;\n}\n```\n\n### Using an object\n\n```js\nvar stack = CreateStack();\n\nstack.Push(10);\nstack.Push(20);\nstack.Push(30);\n\nfunction Operation(op)\n{\n  if(op == \"print\") {\n    Print(stack.Pop());\n  }\n  if(op == \"add\") {\n    var lhs = stack.Pop();\n    var rhs = stack.Pop();\n    stack.Push(lhs + rhs);\n  }\n  if(op == \"mul\") {\n    var lhs = stack.Pop();\n    var rhs = stack.Pop();\n    stack.Push(lhs * rhs);\n  }\n}\n\nOperation(\"mul\");\nOperation(\"add\");\nOperation(\"print\");\n\nPrint(\"Stack Length: \", stack.GetSize());\n```\n\n"

The encoding of these types is described below the table.\n\n| Instruction       | Value | Arguments          | Description                                    |\n| ----------------- | ----- | ------------------ | ---------------------------------------------- |\n| nop               | 0     |                    | No operation                                   |\n| scope_push        | 1     |                    | *reserved*                                     |\n| scope_pop         | 2     |                    | *reserved*                                     |\n| declare           | 3     | `var:str`          | *reserved*                                     |\n| store_global_name | 4     | `var:str`          | stores global variable by name                 |\n| load_global_name  | 5     | `var:str`          | loads global variable by name                  |\n| push_str          | 6     | `val:str`          | pushes string literal                          |\n| push_num          | 7     | `val:f64`          | pushes number literal                          |\n| array_pack        | 8     | `num:u16`          | packs *num* elements into an array             |\n| call_fn           | 9     | `fun:str, argc:u8` | calls a function                               |\n| call_obj          | 10    | `fun:str, argc:u8` | calls an object method                         |\n| pop               | 11    |                    | destroys stack top                             |\n| add               | 12    |                    | adds rhs and lhs together                      |\n| sub               | 13    |                    | subtracts rhs and lhs together                 |\n| mul               | 14    |                    | multiplies rhs and lhs together                |\n| div               | 15    |                    | divides rhs and lhs together                   |\n| mod               | 16    |                    | reminder division of rhs and lhs               |\n| bool_and          | 17    |                    | conjunct rhs and lhs                           |\n| bool_or           | 18    |                    | disjuncts rhs and lhs                          |\n| bool_not          | 19    |                    | logically inverts stack top                    |\n| negate            | 20    |                    | arithmetically inverts stack top               |\n| eq                | 21    |                    |                                                |\n| neq               | 22    |                    |                                                |\n| less_eq           | 23    |                    |                                                |\n| greater_eq        | 24    |                    |                                                |\n| less              | 25    |                    |                                                |\n| greater           | 26    |                    |                                                |\n| jmp               | 27    | `target:u32`       | jumps unconditionally                          |\n| jnf               | 28    | `target:u32`       | jump when not false                            |\n| iter_make         | 29    |                    |                                                |\n| iter_next         | 30    |                    |                                                |\n| array_store       | 31    |                    |                                                |\n| array_load        | 32    |                    |                                                |\n| ret               | 33    |                    | returns from the current function with Void    |\n| store_local       | 34    | `index:u16`        |                                                |\n| load_local        | 35    | `index:u16`        |                                                |\n| retval            | 37    |                    | returns from the current function with a value |\n| jif               | 38    | `target:u32`       | jump when false                                |\n| store_global_idx  | 39    | `idx:u16`          | stores global variable by index                |\n| load_global_idx   | 40    | `idx:u16`          | loads global variable by index                 |\n| push_true | 41 | | pushes a boolean `true` |\n| push_false | 42 | | pushes a boolean `false` |\n| push_void | 43 | | pushes a `void` value. |\n| struct_pack | 44 | `num:u16` | packs *num* named fields into a struct |\n| struct_store | 45 | | stores a value into a struct field |\n| struct_load | 46 | | loads a value from a struct field |\n\n### Types\n\n#### `u8`, `u16`, `u32`\n\nEach of these corresponds to a single, little endian encoded unsigned integer with either 8, 16 or 32 bits width.\n\n#### `f64`\n\nA 64 bit floating point number, encoded with **IEEE 754** *binary64* format, also known as `double`.\n\n#### `str`\n\nA literal string value with a maximum of 65535 bytes length. It's text is encoded in an application-defined encoding where all values below 128 must follow the ASCII encoding scheme. Values equal or above 128 are interpreted by an application-defined logic.\n\nA string is started by a 16 bit unsigned integer defining the length of the string, followed by *length* bytes of content.\n\n**Rationale:** The encoding is not fixed to UTF-8 as the language is meant to be embedded into games where a unicode encoding would be a burden to the player. Thus, a string is defined to be \"at least\" ASCII-compatible and allows UTF-8 encoding, but does not enforce this."

One example is the markdown renderer for the website.\n- [`test`](test/) contains source files that are used to test the compiler and runtime implementation. See `build.zig` and the source files in `library` for the use of those. Each file in this folder has a header that explains its usage."
