Merge of [#1172](https://github.com/mozilla/nunjucks/pull/1172).
Fixes [#1167](https://github.com/mozilla/nunjucks/issues/1167).

* Fix "Invalid type: Is" error for `{% if value is defined %}`. Fixes
[#1110](https://github.com/mozilla/nunjucks/issues/1110)
* Formally drop support for node v4 (the upgrade to babel 7 in 3.1.0 made the
build process incompatible with node < 6.9.0).
3.1.2 (Feb 23 2018)
-------------------
* Fix regression to make `chokidar` an optional dependency again. Fixes
[#1073](https://github.com/mozilla/nunjucks/issues/1073)
* Fix issue when running `npm install nunjucks` with the `--no-bin-links` flag
* Fix regression that broke template caching. Fixes

3.0.1 (May 24 2017)
-------------------
* Fix handling methods and attributes of static arrays, objects and primitives.
Solves the issue [#937](https://github.com/mozilla/nunjucks/issues/937)
* Add support for python-style array slices with Jinja compat enabled.
Fixes [#188](https://github.com/mozilla/nunjucks/issues/188); merge of
[#976](https://github.com/mozilla/nunjucks/pull/976).
* Fix call blocks having access to their parent scope. Fixes
[#906](https://github.com/mozilla/nunjucks/issues/906); merge of
[#994](https://github.com/mozilla/nunjucks/pull/994).
* Fix a bug that caused capturing block tags (e.g. set/endset,
filter/endfilter) to write to the global buffer rather than capturing
their contents. Fixes
[#914](https://github.com/mozilla/nunjucks/issues/914) and
[#972](https://github.com/mozilla/nunjucks/issues/972); merge of
[#990](https://github.com/mozilla/nunjucks/pull/990). Thanks [Noah
Lange](@noahlange).
3.0.0 (Nov 5 2016)
----------------
* Allow including many templates without reaching recursion limits. Merge of
[#787](https://github.com/mozilla/nunjucks/pull/787). Thanks Gleb Khudyakov.
* Allow explicitly setting `null` (aka `none`) as the value of a variable;
don't ignore that value and look on up the frame stack or context. Fixes
[#478](https://github.com/mozilla/nunjucks/issues/478). Thanks Jonny Gerig
Meyer for the report.
* Execute blocks in a child frame that can't write to its parent. This means
that vars set inside blocks will not leak outside of the block, base
templates can no longer see vars set in templates that inherit them, and
`super()` can no longer set vars in its calling scope. Fixes the inheritance
portion of [#561](https://github.com/mozilla/nunjucks/issues/561), which
fully closes that issue. Thanks legutierr for the report.
* Prevent macros from seeing or affecting their calling scope. Merge of
[#667](https://github.com/mozilla/nunjucks/pull/667).
* Fix handling of macro arg with default value which shares a name with another
macro. Merge of [#791](https://github.com/mozilla/nunjucks/pull/791).
* Add support for the spaces parameter in the dump template filter.
Merge of [#868](https://github.com/mozilla/nunjucks/pull/868).
Thanks Jesse Eikema
* Add `verbatim` as an alias of `raw` for compatibility with Twig.
Merge of [#874](https://github.com/mozilla/nunjucks/pull/874).
* Add new `nl2br` filter. Thanks Marc-Aurèle Darche
* Add support for python's `list.append` with Jinja compat enabled. Thanks
Conor Flannigan.
* Add variables whitespace control.
2.5.2 (Sep 14 2016)
----------------
* Call `.toString` in safe filter.
Merge of [#849](https://github.com/mozilla/nunjucks/pull/849).
2.5.1 (Sep 13 2016)
----------------

v2.3.0 (Jan 6 2016)
-------------------
* Return `null` from `WebLoader` on missing template instead of throwing an
error, for consistency with other loaders. This allows `WebLoader` to support
the new `ignore missing` flag on the `include` tag. If `ignore missing` is
not set, a generic "template not found" error will still be thrown, just like
for any other loader. Ajax errors other than 404 will still cause `WebLoader`
to throw an error directly.
* Add preserve-linebreaks option to `striptags` filter. Thanks Ivan
Kleshnin. Merge of [#619](https://github.com/mozilla/nunjucks/pull/619).
v2.2.0 (Nov 23 2015)
--------------------
* Add `striptags` filter. Thanks Anthony Giniers. Merge of
[#589](https://github.com/mozilla/nunjucks/pull/589).
* Allow compiled templates to be imported, included and extended. Thanks Luis
Gutierrez-Sheris. Merge of
[#581](https://github.com/mozilla/nunjucks/pull/581).
* Fix issue with different nunjucks environments sharing same globals. Each
environment is now independent. Thanks Paul Pechin. Merge of
[#574](https://github.com/mozilla/nunjucks/pull/574).
* Add negative steps support for range function. Thanks Nikita Mostovoy. Merge
of [#575](https://github.com/mozilla/nunjucks/pull/575).
* Remove deprecation warning when using the `default` filter without specifying
a third argument. Merge of
[#567](https://github.com/mozilla/nunjucks/pull/567).
* Add support for chaining of addGlobal, addFilter, etc. Thanks Rob Graeber. Merge of
[#537](https://github.com/mozilla/nunjucks/pull/537)
* Fix error propagation. Thanks Tom Delmas. Merge of
[#534](https://github.com/mozilla/nunjucks/pull/534).
* trimBlocks now also trims windows style line endings. Thanks Magnus Tovslid. Merge of
[#548](https://github.com/mozilla/nunjucks/pull/548)
* `include` now supports an option to suppress errors if the template does not
exist. Thanks Mathias Nestler. Merge of
[#559](https://github.com/mozilla/nunjucks/pull/559)
v2.1.0 (Sep 21 2015)
--------------------
* Fix creating `WebLoader` without `opts`. Merge of
[#524](https://github.com/mozilla/nunjucks/pull/524).
* Add `hasExtension` and `removeExtension` methods to `Environment`. Merge of
[#512](https://github.com/mozilla/nunjucks/pull/512).
* Add support for kwargs in `sort` filter. Merge of
[#510](https://github.com/mozilla/nunjucks/pull/510).
* Add `none` as a lexed constant evaluating to `null`. Merge of
[#480](https://github.com/mozilla/nunjucks/pull/480).
* Fix rendering of multiple `raw` blocks. Thanks Aaron O'Mullan. Merge of
[#503](https://github.com/mozilla/nunjucks/pull/503).
* Avoid crashing on async loader error. Thanks Samy Pessé. Merge of
[#504](https://github.com/mozilla/nunjucks/pull/504).
* Add support for keyword arguments for sort filter. Thanks Andres Pardini. Merge of
[#510](https://github.com/mozilla/nunjucks/pull/510)
v2.0.0 (Aug 30 2015)
--------------------
Most of the changes can be summed up in the
[issues tagged 2.0](https://github.com/mozilla/nunjucks/issues?q=is%3Aissue+milestone%3A2.0+is%3Aclosed).
Or you can
[see all commits](https://github.com/mozilla/nunjucks/compare/v1.3.4...f8aabccefc31a9ffaccdc6797938b5187e07ea87).
Most important changes:
* **autoescape is now on by default.** You need to explicitly pass `{
autoescape: false }` in the options to turn it off.
* **watch is off by default.** You need to explicitly pass `{ watch: true }` to
start the watcher.
* The `default` filter has changed. It will show the default value only if the
argument is **undefined**. Any other value, even false-y values like `false`
and `null`, will be returned. You can get back the old behavior by passing
`true` as a 3rd argument to activate the loose-y behavior: `foo |
default("bar", true)`. In 2.0 if you don't pass the 3rd argument, a warning
will be displayed about this change in behavior. In 2.1 this warning will be
removed.
* [New filter tag](http://mozilla.github.io/nunjucks/templating.html#filter)
* Lots of other bug fixes and small features, view the above issue list!
v1.3.4 (Apr 27 2015)
--------------------
This is an extremely minor release that only adds an .npmignore so that the
bench, tests, and docs folders do not get published to npm. Nunjucks should
download a lot faster now.
v1.3.3 (Apr 3 2015)
-------------------
This is exactly the same as v1.3.1, just fixing a typo in the git version tag.
v1.3.2 (Apr 3 2015)
-------------------
(no notes)
v1.3.1 (Apr 3 2015)
-------------------
We added strict mode to all the files, but that broke running nunjucks in the
browser. Should work now with this small fix.
v1.3.0 (Apr 3 2015)
-------------------
* Relative templates: you can now load a template relatively by starting the
path with ., like ./foo.html
* FileSystemLoader now takes a noCache option, if true will disable caching
entirely
* Additional lstripBlocks and trimBlocks available to clean output
automatically
* New selectattr and rejectattr filters
* Small fixes to the watcher
* Several bug fixes
v1.2.0 (Feb 4 2015)
-------------------
* The special non-line-breaking space is considered whitespace now
* The in operator has a lower precedence now. This is potentially a breaking
change, thus the minor version bump. See
[#336](https://github.com/mozilla/nunjucks/pull/336)
* import with context now implemented:
[#319](https://github.com/mozilla/nunjucks/pull/319)
* async rendering doesn't throw compile errors
v1.1.0 (Sep 30 2014)
--------------------
User visible changes:
* Fix a bug in urlize that would remove periods
* custom tag syntax (like {% and %}) was made Environment-specific
internally. Previously they were global even though you set them through the
Environment.
* Remove aggressive optimization that only emitted loop variables when uses. It
introduced several bugs and didn't really improve perf.
* Support the regular expression syntax like /foo/g.
* The replace filter can take a regex as the first argument
* The call tag was implemented
* for tags can now take an else clause
* The cycler object now exposes the current item as the current property
* The chokidar library was updated and should fix various issues
Dev changes:
* Test coverage now available via istanbul. Will automatically display after
running tests.
v1.0.7 (Aug 15 2014)
--------------------
Mixed up a few things in the 1.0.6 release, so another small bump. This merges
in one thing:
* The length filter will not throw an error is used on an undefined
variable. It will return 0 if the variable is undefined.
v1.0.6 (Aug 15 2014)
--------------------
* Added the addGlobal method to the Environment object
* import/extends/include now can take an arbitrary expression
* fix bugs in set
* improve express integration (allows rendering templates without an extension)
v1.0.5 (May 1 2014)
-------------------
* Added support for browserify
* Added option to specify template output path when precompiling templates
* Keep version comment in browser minified files
* Speed up SafeString implementation
* Handle null and non-matching cases for word count filter
* Added support for node-webkit
* Other various minor bugfixes
chokidar repo fix - v1.0.4 (Apr 4 2014)
---------------------------------------
* The chokidar dependency moved repos, and though the git URL should have been
forwarded some people were having issues. This fixed the repo and
version.
(v1.0.3 is skipped because it was published with a bad URL, quickly fixed with
another version bump)
Bug fixes - v1.0.2 (Mar 25 2014)
--------------------------------
* Use chokidar for watching file changes. This should fix a lot of problems on
OS X machines.
* Always use / in paths when precompiling templates
* Fix bug where async filters hang indefinitely inside if statements
* Extensions now can override autoescaping with an autoescape property
* Other various minor bugfixes
v1.0.1 (Dec 16, 2013)
---------------------
(no notes)
We've reached 1.0! Better APIs, asynchronous control, and more (Oct 24, 2013)
-----------------------------------------------------------------------------
* An asynchronous API is now available, and async filters, extensions, and
loaders is supported. The async API is optional and if you don't do anything
async (the default), nothing changes for you. You can read more about this
[here](http://jlongster.github.io/nunjucks/api.html#asynchronous-support). (fixes
[#41](https://github.com/mozilla/nunjucks/issues/41))
* Much simpler higher-level API for initiating/configuring nunjucks is
available. Read more
[here](http://jlongster.github.io/nunjucks/api.html#simple-api).
* An official grunt plugin is available for precompiling templates:
[grunt-nunjucks](https://github.com/jlongster/grunt-nunjucks)
* **The browser files have been renamed.** nunjucks.js is now the full library
with compiler, and nunjucks-slim.js is the small version that only works with
precompiled templates
* urlencode filter has been added
* The express integration has been refactored and isn't a kludge
anymore. Should avoid some bugs and be more future-proof;
* The order in which variables are lookup up in the context and frame lookup
has been reversed. It will now look in the frame first, and then the
context. This means that if a for loop introduces a new var, like {% for name
in names %}, and if you have name in the context as well, it will properly
reference name from the for loop inside the loop. (fixes
[#122](https://github.com/mozilla/nunjucks/pull/122) and
[#119](https://github.com/mozilla/nunjucks/issues/119))
v0.1.10 (Aug 9 2013)
--------------------
(no notes)
v0.1.9 (May 30 2013)
--------------------
(no notes)
v0.1.8 - whitespace controls, unpacking, better errors, and more! (Feb 6 2013)
------------------------------------------------------------------------------
There are lots of cool new features in this release, as well as many critical
bug fixes.
Full list of changes:
* Whitespace control is implemented. Use {%- and -%} to strip whitespace before/after the block.
* `for` loops implement Python-style array unpacking. This is a really nice
feature which lets you do this:
{% for x, y, z in [[2, 2, 2], [3, 3, 3]] %}
--{{ x }} {{ y }} {{ z }}--
{% endfor %}
The above would output: --2 2 2----3 3 3--
You can pass any number of variable names to for and it will destructure each
array in the list to the variables.
This makes the syntax between arrays and objects more
consistent. Additionally, it allows us to implement the `dictsort` filter
which sorts an object by keys or values. Technically, it returns an array of
2-value arrays and the unpacking takes care of it. Example:
{% for k, v in { b: 2, a: 1 } %}
--{{ k }}: {{ v }}--
{% endfor %}
Output: `--b: 2----a: 1--` (note: the order could actually be anything
because it uses javascript’s `for k in obj` syntax to iterate, and ordering
depends on the js implementation)
{% for k, v in { b: 2, a: 1} | dictsort %}
--{{ k }}: {{ v }}--
{% endfor %}
Output: `--a: 1----b: 2--`
The above output will always be ordered that way. See the documentation for
more details.
Thanks to novocaine for this!
* Much better error handling with at runtime (shows template/line/col information for attempting to call undefined values, etc)
* Fixed a regression which broke the {% raw %} block
* Fix some edge cases with variable lookups
* Fix a regression with loading precompiled templates
* Tweaks to allow usage with YUICompressor
* Use the same error handling as normal when precompiling (shows proper errors)
* Fix template loading on Windows machines
* Fix int/float filters
* Fix regression with super()
v0.1.7 - helpful errors, many bug fixes (Dec 12 2012)
-----------------------------------------------------
The biggest change in v0.1.7 comes from devoidfury (thanks!) which implements
consistent and helpful error messages. The errors are still simply raw text,
and not pretty HTML, but they at least contain all the necessary information to
track down an error, such as template names, line and column numbers, and the
inheritance stack. So if an error happens in a child template, it will print
out all the templates that it inherits. In the future, we will most likely
display the actual line causing an error.
Full list of changes:
* Consistent and helpful error messages
* Expressions are more consistent now. Previously, there were several places
that wouldn’t accept an arbitrary expression that should. For example, you
can now do {% include templateNames['foo'] %}, whereas previously you could
only give it a simply variable name.
* app.locals is fixed with express 2.5
* Method calls on objects now have correct scope for this. Version 0.1.6 broke
this and this was referencing the global scope.
* A check was added to enforce loading of templates within the correct
path. Previously you could load a file outside of the template with something
like ../../crazyPrivateFile.txt
You can
[view all the code changes here](https://github.com/jlongster/nunjucks/compare/v0.1.6...v0.1.7). Please
[file an issue](https://github.com/jlongster/nunjucks/issues?page=1&state=open)
if something breaks!
v0.1.6 - undefined handling, bugfixes (Nov 13, 2012)
----------------------------------------------------
This is mostly a bugfix release, but there are a few small tweaks based on
feedback:
* In some cases, backslashes in the template would not appear in the
output. This has been fixed.
* An error is thrown if a filter is not found
* Old versions of express are now supported (2.5.11 was tested)
* References on undefined objects are now suppressed. For example, {{ foo }},
{{ foo.bar }}, {{ foo.bar.baz }} all output nothing if foo is
undefined. Previously only the first form would be suppressed, and a cryptic
error thrown for the latter 2 references. Note: I believe this is a departure
from jinja, which throws errors when referencing undefined objects. I feel
that this is a good and non-breaking addition though. (thanks to devoidfury)
* A bug in set where you couldn’t not reference other variables is fixed
(thanks chriso and panta)
* Other various small bugfixes
You can view
[all the code changes here](https://github.com/jlongster/nunjucks/compare/v0.1.5...v0.1.6). As
always, [file an issue](https://github.com/jlongster/nunjucks/issues) if
something breaks!
v0.1.5 - macros, keyword arguments, bugfixes (Oct 11 2012)
----------------------------------------------------------
v0.1.5 has been pushed to npm, and it’s a big one. Please file any issues you
find, and I’ll fix them as soon as possible!
* The node data structure has been completely refactored to reduce redundancy
and make it easier to add more types in the future.
* Thanks to Brent Hagany, macros now have been implemented. They should act
exactly the way jinja2 macros do.
* A calling convention which implements keyword arguments now exists. All
keyword args are converted into a hash and passed as the last
argument. Macros needed this to implement keyword/default arguments.
* Function and filter calls apply the new keyword argument calling convention
* The “set” block now appropriately only sets a variable for the current scope.
* Many other bugfixes.
I’m watching this release carefully because of the large amount of code that
has changed, so please
[file an issue](https://github.com/jlongster/nunjucks/issues) if you have a
problem with it.

# Contributing
Thanks for your interest in contributing! The advice below will help you get your issue fixed / pull request merged.
## Purpose
Nunjucks has the following purpose:
* Aim for templating feature parity with Jinja2.
* Aim for templating feature parity with Twig, but only when not conflicting with Jinja2 parity.
* Works in all node releases that are
[actively maintained by the Node Foundation](https://github.com/nodejs/Release#release-schedule)
* Works in all modern browsers (with [ES5 support](http://kangax.github.io/compat-table/es5/)).
* Works in IE8 with [es5-shim](https://github.com/es-shims/es5-shim).
* Keep footprint browser files as small as possible (save on bandwidth, download time).
* Keep performance as fast as possible (see benchmarks).
* Keep maintenance as easy as possible (avoid complexity, automate what we can).
Notes:
* We don't aim for parity of all language specific syntax.
* We don't aim for parity of language specific filters like [Twig's PHP date format](http://twig.sensiolabs.org/doc/functions/date.html).
Issues and pull requests contributing to this purpose have the best chance to make it into Nunjucks.

# Pushing a New Version
Nunjucks attempts to adhere to semantic versioning. The API is very stable, so
from here on out it will most likely be point releases.
1. Do a `pull` from github to make sure you have all the latest updates.
2. View all the changes since the last version:
```
$ git log --oneline v1.2.3..master
```
Replace `v1.2.3` with whatever the last version was, and you'll see all the
changes going out in this version. Ensure that all significant user-facing
changes (new features and bugfixes) are mentioned in `CHANGELOG.md`. Change the
"master (unreleased)" heading in `CHANGELOG.md` to the new version number and
date.
3. Update the version in `package.json`.
3. Run the command to update the ready-made files for the browser.
```
$ npm run browserfiles
```
5. Commit above changes and push to `master` (or a release branch, if using one).
6. Draft a new release on GitHub and copy the changelog to the description. The
tag and title should both be the version, in the form `v2.3.0`. Publish the
release.
7. Publish to npm:
```
npm publish
```
8. Make sure docs are up-to-date. You need to copy all the `nunjucks*.js` files
in `browser/` to the docs. This is where the "download" link points to in
the docs. You also need to copy the tests into the docs, for the online
browser tests. ``make prod`` in the ``docs/`` dir will handle these tasks
for you. Push (force push if necessary) the build out _site folder onto the
`gh-pages` branch of the `nunjucks` repo to get it live. One way to do that
is the following commands. These commands presume that you have another
nunjucks git clone inside the (git-ignored) `docs/_site` directory, checked
out to the `gh-pages` branch (and tracking `origin/gh-pages`). (To set that
up the first time, `cd docs/_site`, `rm -rf *`, `git clone
git@github.com:mozilla/nunjucks.git .`, and `git checkout gh-pages`).
```
cd docs && make prod
cd files
python -m SimpleHTTPServer

# API
The API for nunjucks covers rendering templates, adding filters and
extensions, customizing template loading, and more.
## User-Defined Templates Warning
nunjucks does not sandbox execution so **it is not safe to run
user-defined templates or inject user-defined content into template
definitions**. On the server, you can expose attack vectors for
accessing sensitive data and remote code execution. On the client,
you can expose cross-site scripting vulnerabilities even for
precompiled templates (which can be mitigated with a strong
[CSP](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy)). See
[this issue](https://github.com/mozilla/nunjucks-docs/issues/17) for
more information.
## Simple API
If you don't need deep customization of the system, you can use this simple
higher-level API for loading and rendering templates.
{% endraw %}
{% api %}
render
nunjucks.render(name, [context], [callback])
Renders the template named **name** with the **context** hash. If
**callback** is provided, it will be called when done with any
possible error as the first argument and the result as the second.
Otherwise, the result is returned from `render` and errors are thrown.
See [asynchronous support](#asynchronous-support) for more info.
See the warning about **not allowing [users to define their own
templates](#user-defined-templates-warning).**
```js
var res = nunjucks.render('foo.html');
var res = nunjucks.render('foo.html', { username: 'James' });
nunjucks.render('async.html', function(err, res) {
});
```
{% endapi %}
{% api %}
renderString
nunjucks.renderString(str, context, [callback])
Same as [`render`](#render), but renders a raw string instead of
loading a template.
The same warning about **not allowing [users to define their own
templates](#user-defined-templates-warning)** applies.
{% raw %}
```js
var res = nunjucks.renderString('Hello {{ username }}', { username: 'James' });
```
{% endraw %}
{% endapi %}
{% api %}
compile
nunjucks.compile(str, [env], [path])
Compile the given string into a reusable nunjucks Template object.
{% raw %}
```js
var template = nunjucks.compile('Hello {{ username }}');
template.render({ username: 'James' });
```
{% endraw %}
{% endapi %}
{% api %}
configure
nunjucks.configure([path], [opts]);
Tell nunjucks that your templates live at **path** and flip any
feature on or off with the **opts** hash. You can provide both
arguments or either of them. **path** defaults to the current working
directory, and the following options are available in **opts**:
* **autoescape** *(default: true)* controls if output with dangerous characters are
escaped automatically. See [Autoescaping](#autoescaping)
* **throwOnUndefined** *(default: false)* throw errors when outputting a null/undefined value
* **trimBlocks** *(default: false)* automatically remove trailing newlines from a block/tag
* **lstripBlocks** *(default: false)* automatically remove leading whitespace from a block/tag
* **watch** *(default: false)* reload templates when they are changed (server-side). To use watch, make sure optional dependency *chokidar* is installed.
* **noCache** *(default: false)* never use a cache and recompile templates each time (server-side)
* **web** an object for configuring loading templates in the browser:
* **useCache** *(default: false)* will enable cache and templates will never see updates.
* **async** *(default: false)* will load templates asynchronously instead of synchronously (requires use of the [asynchronous API](#asynchronous-support) for rendering).
* **express** an express app that nunjucks should install to
* **tags:** *(default: see nunjucks syntax)* defines the syntax for
nunjucks tags. See [Customizing Syntax](#customizing-syntax)
`configure` returns an `Environment` instance, which lets you add
filters and extensions while still using the simple API. See below for
more information on `Environment`.
**Warning**: The simple API (above; e.g. `nunjucks.render`) always uses the
configuration from the most recent call to `nunjucks.configure`. Since this
is implicit and can result in unexpected side effects, use of the simple API
is discouraged in most cases (especially if `configure` is used); instead,
explicitly create an environment using `var env = nunjucks.configure(...)`
and then call `env.render(...)` etc.
```js
nunjucks.configure('views');
// if in the browser, you probably want to use an absolute URL
nunjucks.configure('/views');
nunjucks.configure({ autoescape: true });
nunjucks.configure('views', {
autoescape: true,
express: app,
watch: true
});
var env = nunjucks.configure('views');
// do stuff with env
```
{% endapi %}
{% api %}
installJinjaCompat
nunjucks.installJinjaCompat()
This installs experimental support for more consistent Jinja
compatibility by adding Pythonic APIs to the environment. While
nunjucks does not aim for complete Jinja/Python compatibility, this
might help users seeking just that.
This adds `True` and `False` which map to the JS `true` and `false`
values, allows use of Python slice syntax, and augments arrays and
objects with Python-style methods.
[Check out the source](https://github.com/mozilla/nunjucks/blob/master/nunjucks/src/jinja-compat.js)
to see everything it adds.
{% endapi %}
{% raw %}
*That's it for the simple API! If you want total control over how
templates are loaded, and more customization, you need to manually
set up the system as seen below.*
## Environment
The `Environment` class is the central object which handles templates.
It knows how to load your templates, and internally templates depend
on it for inheritance and including templates. The simple API above
dispatches everything to an `Environment` instance that it keeps for
you.
You can manually handle it if you want, which allows you to specify
custom template loaders.
{% endraw %}
{% api %}
constructor
new Environment([loaders], [opts])
The constructor takes a list of **loaders** and a hash of
configuration parameters as **opts**. If **loaders** is null, it
defaults to loading from the current directory or URL. You can pass a
single loader or an array of loaders. If you pass an array of loaders,
nunjucks will walk through them in order until one of them finds a
template. See [`Loader`](#loader) for more info about loaders.
The available flags in **opts** is **autoescape**,
**throwOnUndefined**, **trimBlocks**, and **lstripBlocks**.
Read more about those options in [`configure`](#configure) (the
express and watch options are not applicable here and configured
elsewhere like [`env.express`](#express)).
In node, the [`FileSystemLoader`](#filesystemloader) is available to
load templates off the filesystem, and in the browser the [`WebLoader`](#webloader)
is available to load over HTTP (or use precompiled templates). If you
use the simple [`configure`](#configure) API, nunjucks automatically
creates the appropriate loader for you, depending if you're in node or
the browser. See [`Loader`](#loader) for more information.
Also only in node, [`NodeResolveLoader`](#noderesolveloader) is
provided to allow templates to be included using
[node `require` resolution](https://nodejs.org/api/modules.html#modules_all_together).
This is not enabled by default with [`configure`](#configure), it must be
explicitly passed into the `Environment` constructor.
```js
// the FileSystemLoader is available if in node
var env = new nunjucks.Environment(new nunjucks.FileSystemLoader('views'));
var env = new nunjucks.Environment(new nunjucks.FileSystemLoader('views'),
{ autoescape: false });
var env = new nunjucks.Environment([new nunjucks.FileSystemLoader('views'),
new MyCustomLoader()]);
// the WebLoader is available if in the browser
var env = new nunjucks.Environment(new nunjucks.WebLoader('/views'));
```
{% endapi %}
{% api %}
render
env.render(name, [context], [callback])
Render the template named **name** with the optional **context** hash.
If **callback** is supplied, call it when done with any errors and the
result (see [asynchronous support](#asynchronous-support)), otherwise
return the rendered string.
```js
var res = nunjucks.render('foo.html');
var res = nunjucks.render('foo.html', { username: 'James' });
nunjucks.render('async.html', function(err, res) {
});
```
{% endapi %}
{% api %}
renderString
env.renderString(src, [context], [callback])
Same as [`render`](#render1), but renders a raw string instead of
loading a template.
{% raw %}
```js
var res = nunjucks.renderString('Hello {{ username }}', { username: 'James' });
```
{% endraw %}
{% endapi %}
{% api %}
addFilter
env.addFilter(name, func, [async])
Add a custom filter named **name** which calls **func** whenever
invoked. If the filter needs to be async, **async** must be `true`
(see [asynchronous support](#asynchronous-support)). Returns `env` for further method chaining. See
[Custom Filters](#custom-filters).
{% endapi %}
{% api %}
getFilter
env.getFilter(name)
Get the filter, which is just a function, named **name**.
{% endapi %}
{% api %}
addExtension
env.addExtension(name, ext)
Add the custom extension **ext** named **name**. **ext** is an object
with a few specific methods that are called by the extension system. Returns `env` for further method chaining.
See [Custom Tags](#custom-tags).
{% endapi %}
{% api %}
removeExtension
env.removeExtension(name)
Remove a previously added custom extension named **name**.
{% endapi %}
{% api %}
getExtension
env.getExtension(name)
Get an extension named **name**.
{% endapi %}
{% api %}
hasExtension
env.hasExtension(name)
Return true if a custom extension named **name** has been added.
{% endapi %}
{% api %}
addGlobal
env.addGlobal(name, value)
Add a global value that will be available to all templates. Note: this will overwrite any existing global called `name`.
Returns `env` for further method chaining.
{% endapi %}
{% api %}
getGlobal
env.getGlobal(name)
Get a global named **name**.
{% endapi %}
{% api %}
getTemplate
env.getTemplate(name, [eagerCompile], [callback])
Retrieve the template named **name**. If **eagerCompile** is `true`,
compile it now instead of on render. If **callback** is supplied, call
it with any errors and a template (if found), otherwise return
synchronously. If using any async loaders, you must use the async API.
The builtin loaders do not require this. See
[asynchronous support](#asynchronous-support) and [loaders](#loader).
```js
var tmpl = env.getTemplate('page.html');
var tmpl = env.getTemplate('page.html', true);
env.getTemplate('from-async-loader.html', function(err, tmpl) {
});
```
{% endapi %}
{% api %}
express
env.express(app)
Install nunjucks as the rendering engine for the express **app**.
After doing this, you can use express normally. Note that you can do
this automatically with the simple API call [`configure`](#configure)
by passing in the app as the **express** option. Returns `env` for further method chaining.
```js
var app = express();
env.express(app);
app.get('/', function(req, res) {
res.render('index.html');
});
```
{% endapi %}
{% api %}
opts.autoescape
env.opts.autoescape
You can use this boolean property to see if autoescaping is turned on
globally or not. This may be helpful in creating advanced filtering
that do HTML manipulation. Normally you should simply return a
SafeString (to be documented) if one was passed in, so the output will
copy the safeness of the input, but this property is helpful in rare
circumstances.
{% endapi %}
{% api %}
'load' event
env.on('load', function(name, source, loader))
The 'load' event gets emitted whenever a Loader retrieves the source of a
template. It can be listened to in order to determine template dependencies
at runtime. The arguments emitted to the callback are:
* **name** *(String)* The template name, as passed to the loader
* **source** *(Object)* The object that gets returned from Loader.getSource
* **src** *(String)* The template source
* **path** *(String)* The full path to the template
* **noCache** *(Bool)* If `true`, the template wasn't cached.
* **loader** The Loader instance that triggered the event.
{% endapi %}
{% raw %}
## Template
A `Template` is an object that handles the compiling of template
strings and rendering them. Usually the `Environment` handles them for
you, but you can easily use it yourself. If you don't connect a
template with an environment, you can't include or inherit any other
templates.
{% endraw %}
{% api %}
constructor
new Template(src, [env], [path], [eagerCompile])
The constructor takes a template string **src**, an optional
`Environment` instance **env** to use for loading other templates, a
string **path** describing the location/path for debugging purposes,
and a boolean **eagerCompile** which, if `true`, kicks off compilation
immediately instead of waiting until the template is rendered.
{% raw %}
```js
var tmpl = new nunjucks.Template('Hello {{ username }}');
tmpl.render({ username: "James" }); // -> "Hello James"
```
{% endraw %}
{% endapi %}
{% api %}
render
tmpl.render(context, [callback])
Renders the template with the optional **context** hash. If
**callback** is supplied, call it when done with any errors and the
result (see [asynchronous support](#asynchronous-support)), otherwise
return the rendered string.
{% endapi %}
{% raw %}
## Loader
A loader is an object that takes a template name and loads it from a
source, such as the filesystem or network. The following two builtin
loaders exist, each for different contexts.
{% endraw %}
{% api %}
FileSystemLoader
new FileSystemLoader([searchPaths], [opts])
This is only available to node. It will load templates from the
filesystem, using the **searchPaths** array as paths to look for
templates. **searchPaths** can also be a single path for where
templates live, and it defaults to the current working directory.
**opts** is an object with the following optional properties:
* **watch** - if `true`, the system will automatically update templates. To use watch, make sure optional dependency *chokidar* is installed.
when they are changed on the filesystem
* **noCache** - if `true`, the system will avoid using a cache and templates
will be recompiled every single time
```js
// Loads templates from the "views" folder
var env = new nunjucks.Environment(new nunjucks.FileSystemLoader('views'));
```
{% endapi %}
{% api %}
NodeResolveLoader
new NodeResolveLoader([opts])
As the name suggests, this is also only available in node. It will load
templates from the filesystem using node's
[`require.resolve`](https://nodejs.org/api/modules.html#modules_all_together).
**opts** is an object which takes the same properties as
[`FileSystemLoader`](#filesystemloader).
{% endapi %}
{% api %}
WebLoader
new WebLoader([baseURL], [opts])
This is only available in the browser. **baseURL** is the URL to load
templates from (must be the same domain), and it defaults to the
current relative directory.
**opts** is an object with the following optional properties:
* **useCache** if `true`, templates will be forever cached and you
won't see updates to them. The cache is disabled by default
because there is no way to watch for changes and dirty the cache.
Remember, you should be precompiling your templates for production.
* **async** if `true`, templates will be loaded asynchronously instead
synchronously. You must use the asynchronous render API when using
this (pass a callback to `render`).
This loader also recognizes when precompiled templates are available
and automatically uses them instead of fetching over HTTP. In
production, this should always be the case. See
[Precompiling](#precompiling).
```js
// Load templates from /views
var env = new nunjucks.Environment(new nunjucks.WebLoader('/views'))
```
{% endapi %}
{% raw %}
### Writing a Loader
You can write loaders for more complex loading, like from a database.
If you want to do this, just create an object that has a method
`getSource(name)`, where **name** is the name of the template. That's it.
```js
function MyLoader(opts) {
// configuration
}
MyLoader.prototype.getSource = function(name) {
// load the template
// return an object with:
// - src: String. The template source.
// - path: String. Path to template.
// - noCache: Bool. Don't cache the template (optional).
}
```
It can get a little more complex. If you want to track updates to
templates and bust the internal cache so that you can see updates, you
need to extend the `Loader` class. This gives you `emit` method that
can fire events. You need to call it
```js
var MyLoader = nunjucks.Loader.extend({
init: function() {
// setup a process which watches templates here
// and call `this.emit('update', name)` when a template
// is changed
},
getSource: function(name) {
// load the template
}
});
```
#### Asynchronous
There's one last piece: asynchronous loaders. So far, all of the
loaders have been synchronous; `getSource` returns the source
immediately. The benefit of this is that the user isn't forced to use
the asynchronous API and be aware of edge cases about async templates.
You might want to load from a database, however.
Just add an `async: true` property to your loader and it will be used
asynchronously.
```js
var MyLoader = nunjucks.Loader.extend({
async: true,
getSource: function(name, callback) {
// load the template
// ...
callback(err, res);
}
});
```
Remember that you now have to use the asynchronous API. See
[asynchronous support](#asynchronous-support).
**Warning**: if you are using an asynchronous loader, you can't load
templates inside `for` loops. You need to explicitly use the
`asyncEach` tag if you need to load templates, which is exactly the
same as `for` but asynchronous. More info can be found at
[Be Careful!](#be-careful).
## Browser Usage
Using nunjucks in the browser takes a little more thought because you
care about load and compile time. On the server-side, templates are
compiled once and cached in memory and you never have to worry about
it. On the client-side however, you don't want to compile templates
even once, as it would result in slow page render time.
The solution is to precompile your templates into JavaScript, and load
them as a simple `.js` file on page load.
Maybe you do want to dynamically load templates while developing,
however, so that you can see changes immediately without recompiling.
Nunjucks tries to adapt to whatever workflow you want.
The only rule you must follow: **always precompile your templates in
production**. Why? Not only is it slow to compile all your templates
on page load, they are loaded *synchronously* over HTTP, blocking the
whole page. It is slow. It does this because nunjucks isn't async by
default.
### Recommended Setups
These are two of the most popular ways to set up nunjucks on the
client-side. Note that there are two different js files: one with the
compiler, nunjucks.js, and one without the compiler, nunjucks-slim.js.
Read [Getting Started](getting-started.html) for a brief overview of
the differences.
See [Precompiling](#precompiling) for information on precompiling
templates.
#### Setup #1: only precompile in production
This method will give you a setup that dynamically loads templates
while developing (you can see changes immediately), but uses
precompiled templates in production.
1. Load [nunjucks.js](files/nunjucks.js) with either a script tag or a module loader.
2. Render templates ([example](#simple-api))!
3. When pushing to production, [precompile](#precompiling) the templates into a js file
and load it on the page
> An optimization is to use `nunjucks-slim.js` instead of
> `nunjucks.js` in production since you are using precompiled
> templates there. It's 8K instead of 20K because it doesn't contain
> the compiler. This complicates the setup though because you are
> using different js files between dev and prod, so it may or may not
> be worth it.
#### Setup #2: always precompile
This method always uses precompiled templates while developing and in
production, which simplifies the setup. However, you're going to want
something that automatically recompiles templates while developing
unless you want to manually recompile them after every change.
1. For development, use the [grunt](https://github.com/jlongster/grunt-nunjucks) or
[gulp](https://github.com/sindresorhus/gulp-nunjucks) tasks to watch your template
directory for changes and automatically [precompile](#precompiling) them into a js file
2. Load [nunjucks-slim.js](files/nunjucks-slim.js) and `templates.js`, or whatever you named
the precompiled js file, with either a script tag or a module loader.
3. Render templates ([example](#simple-api))!
With this method, there are no differences between development and
production code. Simply commit the templates.js file and deploy the
same code to production.
## Precompiling
To precompile your templates, use the `nunjucks-precompile` script
that comes with nunjucks. You can pass it a directory or a file and it
will generate all the JavaScript for your templates.
```
// Precompiling a whole directory
$ nunjucks-precompile views > templates.js
// Precompiling individual templates
$ nunjucks-precompile views/base.html >> templates.js
$ nunjucks-precompile views/index.html >> templates.js
$ nunjucks-precompile views/about.html >> templates.js
```
All you have to do is simply load `templates.js` on the page, and the
system will automatically use the precompiled templates. There are
zero changes necessary.
There are various options available to the script. Simply invoke
`nunjucks-precompile` to see more info about them. Note that **names
of all asynchronous filters need to passed to the script** since they
need to be known at compile-time. You can pass a comma-delimited list
of async filters with `-a`, like `-a foo,bar,baz`. If you only use
normal synchronous filters, you don't need to do anything.
Extensions cannot be specified with this script. You must use the
precompile API below if you use them.
### API
There is also an API if you want to programmatically precompile
templates. You'll want to do this if you use extensions or you use
asynchronous filters, both of which need to be known at compile-time.
You can pass an `Environment` object straight into the precompiler and
it will get the extensions and filters from it. You should share the
same `Environment` object between the client and server to keep
everything in sync.

precompile
nunjucks.precompile(path, [opts])
Precompile a file or directory at **path**. **opts** is a hash with any of the following options:
* **name**: name of the template, when compiling a string (required)
or a file (optional, defaults to **path**). names are
auto-generated when compiling a directory.
* **asFunction**: generate a callable function
* **force**: keep compiling on error
* **env**: the Environment to use (gets extensions and async filters from it)
* **include**: array of file/folders to include (folders are auto-included, files are auto-excluded)
* **exclude**: array of file/folders to exclude (folders are auto-included, files are auto-excluded)
* **wrapper**: `function(templates, opts)` Customize the output format of the precompiled templates. This function must return a string
* **templates**: array of objects with the following properties:
* **name**: name of the template
* **template**: string source of the precompiled template in javascript
* **opts**: object of all the above options
```js
var env = new nunjucks.Environment();
// extensions must be known at compile-time
env.addExtension('MyExtension', new MyExtension());
// async filters must be known at compile-time
env.addFilter('asyncFilter', function(val, cb) {
// do something
}, true);
nunjucks.precompile('/dir/to/views', { env: env });
```
{% endapi %}
{% api %}
precompileString
nunjucks.precompileString(str, [opts])
Exactly the same as [`precompile`](#precompile), but compiles a raw string.

## Asynchronous Support
You only need to read this section if you are interested in
asynchronous rendering. There is no performance benefit to this, it is
solely to allow custom filters and extensions to make async calls. If
you don't care about this, you should simply use the normal API like
`var res = env.render('foo.html');`. There's no need to force the
`callback` on you, and it's why it's optional in all the rendering
functions.
As of version 1.0, nunjucks provides a way to render templates
asynchronously. This means that custom filters and extensions can do
stuff like fetch things from the database, and template rendering is
"paused" until the callback is called.
Template loaders can be async as well, allowing you to load templates
from a database or somewhere else. See
[Writing a Loader](#writing-a-loader). If you are using an async
template loader, you must use the async API. The builtin loaders that
load from the filesystem and over HTTP are synchronous, which is not a
performance problem because they are cached from the filesystem and
you should precompile your templates and never use HTTP in production.
If you are using anything async, you need to use the async API like this:
```js
nunjucks.render('foo.html', function(err, res) {
// check err and handle result
});
```
Read more about async [`filters`](#asynchronous1), [`extensions`](#asynchronous2), and
[`loaders`](#asynchronous).
### Be Careful!
Nunjucks is synchronous by default. Because of this, you need to
follow a few rules when writing asynchronous templates:
* Always use the async API. `render` should take a function that takes
a callback.
* Async filters and extensions need to be known at compile-time, so
you need to specify them explicitly when precompiling (see
[Precompiling](#precompiling)).
* If you are using a custom template loader that is asynchronous, you
can't include templates inside a `for` loop. This is because `for`
will compile to an imperative JavaScript `for` loop. You need to
explicitly use the async `asyncEach` tag to iterate, which is
exactly the same as `for` except asynchronous.
## Autoescaping
By default, nunjucks will escape all output. It's recommended
that you do this for security reasons. If you turn off autoescaping,
nunjucks will render all output as it is by default.
To deactivate it, all you have to do is pass the `autoescape` option as
`false` to the `Environment` object.
```js
var env = nunjucks.configure('/path/to/templates', { autoescape: false });
```
## Customizing Syntax
If you want different tokens than `{{` and the rest for variables,
blocks, and comments, you can specify different tokens as the `tags`
option:
```js
var env = nunjucks.configure('/path/to/templates', {
tags: {
blockStart: '<%',
blockEnd: '%>',
variableStart: '<$',
variableEnd: '$>',
commentStart: '<#',
commentEnd: '#>'
}
});
```
Using this environment, templates will look like this:
```
<% for item in items %>
<$ item $>
<% endfor %>
```
## Custom Filters
To install a custom filter, use the `Environment` method `addFilter`.
A filter is simply a function that takes the target object as the
first argument and any arguments passed to the filter as the other
arguments, in order.
```js
var nunjucks = require('nunjucks');
var env = new nunjucks.Environment();
env.addFilter('shorten', function(str, count) {
return str.slice(0, count || 5);
});
```
This adds a filter `shorten` which returns the first `count`
characters in a string, with `count` defaulting to 5. Here is how it
is used:
```jinja
{# Show the first 5 characters #}
A message for you: {{ message|shorten }}
{# Show the first 20 characters #}
A message for you: {{ message|shorten(20) }}
```
### Keyword/Default Arguments
As described in the
[templating section](templating#keyword-arguments), nunjucks supports
keyword/default arguments. You can write a normal javascript filter
that leverages them.
All keyword arguments are passed in as a hash as the last argument.
This is a filter `foo` that uses keyword arguments:
```js
env.addFilter('foo', function(num, x, y, kwargs) {
return num + (kwargs.bar || 10);
})
```
The template can use it like this:
```jinja
{{ 5 | foo(1, 2) }} -> 15
{{ 5 | foo(1, 2, bar=3) }} -> 8
```
You *must* pass all of the positional arguments before keyword
arguments (`foo(1)` is valid but `foo(1, bar=10)` is not). Also, you
cannot set a positional argument with a keyword argument like you can
in Python (such as `foo(1, y=1)`)
### Asynchronous
Asynchronous filters receive a callback to resume rendering, and are
created by passing `true` as the third argument to `addFilter`.
```js
var env = nunjucks.configure('views');
env.addFilter('lookup', function(name, callback) {
db.getItem(name, callback);
}, true);
env.renderString('{{ item|lookup }}', function(err, res) {
// do something with res
});
```
Make sure to call the callback with two arguments: `callback(err, res)`. `err` can be null, of course.
Note: When precompiling, **you must tell the precompiler the names of
all asynchronous filters**. See
[Precompiling](#precompiling).
## Custom Tags
You can create more complicated extensions by creating custom tags.
This exposes the parser API and allows you to do anything you want
with the template.
Note: When precompiling, **you must install the extensions at
compile-time**. You have to use the [precompiling API](#api1) (or the
[grunt](https://github.com/jlongster/grunt-nunjucks) or
[gulp](https://github.com/sindresorhus/gulp-nunjucks) tasks) instead of
the script. You'll want to create an [`Environment`](#environment)
object, install your extensions, and pass it to the precompiler.
An extension is a javascript object with at least two fields: `tags`
and `parse`. Extensions basically register new tag names and take
control of the parser when they are hit.
`tags` is an array of tag names that the extension should handle.
`parse` is the method that actually parses them when the template is
compiled. Additionally, there is a special node type `CallExtension`
that you can use to call any method on your extension at runtime. This
is explained more below.
Because you have to interact directly with the parse API and construct
ASTs manually, this is a bit cumbersome. It's necessary if you want to
do really complex stuff, however. Here are a few key parser methods
you'll want to use:
* `parseSignature([throwErrors], [noParens])` - Parse a list of
arguments. By default it requires the parser to be pointing at the
left opening parenthesis, and parses up the right one. However, for
custom tags you shouldn't use parentheses, so passing `true` to the
second argument tells it to parse a list of arguments up until the
block end tag. A comma is required between arguments. Example: `{%
mytag foo, bar, baz=10 %}`
* `parseUntilBlocks(names)` - Parse content up until it hits a block
with a name in the `names` array. This is useful for parsing content
between tags.
The parser API needs to be more documented, but for now read the above
and check out the example below. You can also look at the
[source](https://github.com/mozilla/nunjucks/blob/master/nunjucks/src/parser.js).
The most common usage is to process the content within some tags at
runtime. It's like filters, but on steroids because you aren't
confined to a single expression. You basically want to lightly parse
the template and then get a callback into your extension with the
content. This is done with the `CallExtension` node, which takes an
extension instance, the method to call, list of arguments parsed from
the tag, and a list of content blocks (parsed with
`parseUntilBlocks`).
For example, here's how you would implement an extension that fetches
content from a URL and injects it into the page:
```js
function RemoteExtension() {
this.tags = ['remote'];
this.parse = function(parser, nodes, lexer) {
// get the tag token
var tok = parser.nextToken();
// parse the args and move after the block end. passing true
// as the second arg is required if there are no parentheses
var args = parser.parseSignature(null, true);
parser.advanceAfterBlockEnd(tok.value);
// parse the body and possibly the error block, which is optional
var body = parser.parseUntilBlocks('error', 'endremote');
var errorBody = null;
if(parser.skipSymbol('error')) {
parser.skip(lexer.TOKEN_BLOCK_END);
errorBody = parser.parseUntilBlocks('endremote');
}
parser.advanceAfterBlockEnd();
// See above for notes about CallExtension
return new nodes.CallExtension(this, 'run', args, [body, errorBody]);
};
this.run = function(context, url, body, errorBody) {
var id = 'el' + Math.floor(Math.random() * 10000);
var ret = new nunjucks.runtime.SafeString('
' + body() + '
');
var ajax = new XMLHttpRequest();
ajax.onreadystatechange = function() {
if(ajax.readyState == 4) {
if(ajax.status == 200) {
document.getElementById(id).innerHTML = ajax.responseText;
}
else {
document.getElementById(id).innerHTML = errorBody();
}
}
};
ajax.open('GET', url, true);
ajax.send();
return ret;
};
}
env.addExtension('RemoteExtension', new RemoteExtension());
```
Use it like this:
```jinja
{% remote "/stuff" %}
This content will be replaced with the content from /stuff
{% error %}
There was an error fetching /stuff
{% endremote %}
```
### Asynchronous
Another available node is `CallExtensionAsync` which is an
asynchronous version of `CallExtension`. It calls back into your
extension at runtime, with an additional parameter: a callback.
Template rendering is paused until you call the callback to resume.
The `run` function from the above example would now look like:
```js
this.run = function(context, url, body, errorBody, callback) {
// do async stuff and then call callback(err, res)
};
```

# Contributing to Bootstrap
Looking to contribute something to Bootstrap? **Here's how you can help.**
## Reporting issues
We only accept issues that are bug reports or feature requests. Bugs must be isolated and reproducible problems that we can fix within the Bootstrap core. Please read the following guidelines before opening any issue.
1. **Search for existing issues.** We get a lot of duplicate issues, and you'd help us out a lot by first checking if someone else has reported the same issue. Moreover, the issue may have already been resolved with a fix available.
2. **Create an isolated and reproducible test case.** Be sure the problem exists in Bootstrap's code with a [reduced test case](http://css-tricks.com/reduced-test-cases/) that should be included in each bug report.
3. **Include a live example.** Make use of jsFiddle or jsBin to share your isolated test cases.
4. **Share as much information as possible.** Include operating system and version, browser and version, version of Bootstrap, customized or vanilla build, etc. where appropriate. Also include steps to reproduce the bug.
## Key branches
- `master` is the latest, deployed version.
- `gh-pages` is the hosted docs (not to be used for pull requests).
- `*-wip` is the official work in progress branch for the next release.
## Pull requests
- Try to submit pull requests against the latest `*-wip` branch for easier merging
- CSS changes must be done in .less files first, never just the compiled files
- If modifying the .less files, always recompile and commit the compiled files bootstrap.css and bootstrap.min.css
- Try not to pollute your pull request with unintended changes--keep them simple and small
- Try to share which browsers your code has been tested in before submitting a pull request
## Coding standards
### HTML
- Two spaces for indentation, never tabs
- Double quotes only, never single quotes
- Always use proper indentation
- Use tags and elements appropriate for an HTML5 doctype (e.g., self-closing tags)
### CSS
- Adhere to the [Recess CSS property order](http://markdotto.com/2011/11/29/css-property-order/)
- Multiple-line approach (one property and value per line)
- Always a space after a property's colon (.e.g, `display: block;` and not `display:block;`)
- End all lines with a semi-colon
- For multiple, comma-separated selectors, place each selector on its own line
- Attribute selectors, like `input[type="text"]` should always wrap the attribute's value in double quotes, for consistency and safety (see this [blog post on unquoted attribute values](http://mathiasbynens.be/notes/unquoted-attribute-values) that can lead to XSS attacks).
### JS
- No semicolons
- Comma first
- 2 spaces (no tabs)
- strict mode
- "Attractive"

# [Bootstrap v3.0.0](http://getbootstrap.com) [](http://travis-ci.org/twbs/bootstrap)
Bootstrap is a sleek, intuitive, and powerful front-end framework for faster and easier web development, created and maintained by [Mark Otto](http://twitter.com/mdo) and [Jacob Thornton](http://twitter.com/fat).
To get started, check out [http://getbootstrap.com](http://getbootstrap.com)!
## Quick start
Three quick start options are available:
* [Download the latest release](https://github.com/twbs/bootstrap/zipball/3.0.0-wip).
* Clone the repo: `git clone git://github.com/twbs/bootstrap.git`.
* Install with [Bower](http://bower.io): `bower install bootstrap`.
Read the [Getting Started page](http://getbootstrap.com/getting-started/) for information on the framework contents, templates and examples, and more.
## Bugs and feature requests
Have a bug or a feature request? [Please open a new issue](https://github.com/twbs/bootstrap/issues). Before opening any issue, please search for existing issues and read the [Issue Guidelines](https://github.com/necolas/issue-guidelines), written by [Nicolas Gallagher](https://github.com/necolas/).
You may use [this JS Bin](http://jsbin.com/aKiCIDO/1/edit) as a template for your bug reports.
## Documentation
Bootstrap's documentation, included in this repo in the root directory, is built with [Jekyll](http://jekyllrb.com) and publicly hosted on GitHub Pages at [http://getbootstrap.com](http://getbootstrap.com). The docs may also be run locally.
### Running documentation locally
1. If necessary, [install Jekyll](http://jekyllrb.com/docs/installation) (requires v1.x).
2. From the root `/bootstrap` directory, run `jekyll serve` in the command line.
- **Windows users:** run `chcp 65001` first to change the command prompt's character encoding ([code page](http://en.wikipedia.org/wiki/Windows_code_page)) to UTF-8 so Jekyll runs without errors.
3. Open [http://localhost:9001](http://localhost:9001) in your browser, and voilà.
Learn more about using Jekyll by reading their [documentation](http://jekyllrb.com/docs/home/).
### Documentation for previous releases
Documentation for v2.3.2 has been made available for the time being at [http://getbootstrap.com/2.3.2/](http://getbootstrap.com/2.3.2/) while folks transition to Bootstrap 3.
[Previous releases](https://github.com/twbs/bootstrap/releases) and their documentation are also available for download.
## Compiling CSS and JavaScript
Bootstrap uses [Grunt](http://gruntjs.com/) with convenient methods for working with the framework. It's how we compile our code, run tests, and more. To use it, install the required dependencies as directed and then run some Grunt commands.
### Install Grunt
From the command line:
1. Install `grunt-cli` globally with `npm install -g grunt-cli`.
2. Install the [necessary local dependencies](package.json) via `npm install`
When completed, you'll be able to run the various Grunt commands provided from the command line.
**Unfamiliar with `npm`? Don't have node installed?** That's a-okay. npm stands for [node packaged modules](http://npmjs.org/) and is a way to manage development dependencies through node.js. [Download and install node.js](http://nodejs.org/download/) before proceeding.
### Available Grunt commands
#### Build - `grunt`
Run `grunt` to run tests locally and compile the CSS and JavaScript into `/dist`. **Requires [recess](https://github.com/twitter/recess) and [uglify-js](https://github.com/mishoo/UglifyJS).**
#### Only compile CSS and JavaScript - `grunt dist`
`grunt dist` creates the `/dist` directory with compiled files. **Requires [recess](https://github.com/twitter/recess) and [uglify-js](https://github.com/mishoo/UglifyJS).**
#### Tests - `grunt test`
Runs jshint and qunit tests headlessly in [phantomjs](https://github.com/ariya/phantomjs/) (used for CI). **Requires [phantomjs](https://github.com/ariya/phantomjs/).**
#### Watch - `grunt watch`
This is a convenience method for watching just Less files and automatically building them whenever you save.
### Troubleshooting dependencies
Should you encounter problems with installing dependencies or running Grunt commands, uninstall all previous dependency versions (global and local). Then, rerun `npm install`.
## Contributing
Please read through our guidelines for contributing to Bootstrap. Included are directions for opening issues, coding standards, and notes on development.
More over, if your pull request contains JavaScript patches or features, you must include relevant unit tests. All HTML and CSS should conform to the [Code Guide](http://github.com/mdo/code-guide), maintained by [Mark Otto](http://github.com/mdo).
Editor preferences are available in the [editor config](.editorconfig) for easy use in common text editors. Read more and download plugins at [http://editorconfig.org](http://editorconfig.org).
## Community
Keep track of development and community news.
* Follow [@twbootstrap on Twitter](http://twitter.com/twbootstrap).
* Read and subscribe to the [The Official Bootstrap Blog](http://blog.getbootstrap.com).
* Have a question that's not a feature request or bug report? [Ask on the mailing list.](http://groups.google.com/group/twitter-bootstrap)
* Chat with fellow Bootstrappers in IRC. On the `irc.freenode.net` server, in the `##twitter-bootstrap` channel.
## Versioning
For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Bootstrap will be maintained under the Semantic Versioning guidelines as much as possible.
Releases will be numbered with the following format:
`..`
And constructed with the following guidelines:
* Breaking backward compatibility bumps the major (and resets the minor and patch)
* New additions without breaking backward compatibility bumps the minor (and resets the patch)
* Bug fixes and misc changes bumps the patch
For more information on SemVer, please visit [http://semver.org/](http://semver.org/).
