Installing YUI Compressor
=========================
To use `YUI Compressor`_ you must install Java. Once Java has been installed
make sure to set ``JAVA_BIN`` in your application config.
You can download YUI Compressor from
`<https://github.com/yui/yuicompressor/downloads>`_ and make sure that
``YUI_COMPRESSOR_BIN`` points to the ``yuicompressor-x.y.z.jar`` file.
Configuration
=============
There are several configuration options available for **Flask-Funnel**:
**CSS_BUNDLES**
A dict of CSS bundles:
.. code-block:: python
app.config['CSS_BUNDLES'] = {
'bundle1': (
'stylesheet.css',
'another.css',
'tobecompile.less',
'tobecompile2.scss',
),
}
Defaults to: ``{}``
**JS_BUNDLES**
A dict of JavaScript bundles:
.. code-block:: python
app.config['JS_BUNDLES'] = {
'the_bundle': (
'jquery.js',
'jquery-ui.js',
'tubecompile.coffee',
),
}
Defaults to: ``{}``
**CSS_MEDIA_DEFAULT**
This is the default value for the media attribute of the <link> tag for
stylesheets.
Defaults to: ``'screen,projection,tv'``
**BUNDLES_DIR**
The subdirectory of the static directory that the generated bundles are saved
to.
Defaults to: ``'bundles'``
**YUI_COMPRESSOR_BIN**
If you plan on using `YUI Compressor`_ you must set this variable.
*It has no default value.*
**JAVA_BIN**
If you plan on using `YUI Compressor`_ you must set this variable.
*It has no default value.*
**LESS_BIN**
If you require `LESS`_ support you must point this to ``lessc``.
Defaults to: ``'lessc'``
**LESS_PREPROCESS**
If you want LESS files to be compiled when ``app.debug`` is ``True`` and
compressed files are not being used.
Defaults to: ``True``
**SCSS_BIN**
If you require `SCSS`_ support you must point this to ``scss``.
Defaults to: ``'scss'``
**SCSS_PREPROCESS**
If you want SCSS files to be compiled when ``app.debug`` is ``True`` and
compressed files are not being used.
Defaults to: ``True``
**STYLUS_BIN**
If you require `Stylus`_ support you must point this to ``stylus``.
Defaults to: ``'stylus'``
**STYLUS_PREPROCESS**
If you want Stylus files to be compiled when ``app.debug`` is ``True`` and
compressed files are not being used.
Defaults to: ``True``
**COFFEE_BIN**
If you require `COFFEE`_ support you must point this to ``coffee``.
Defaults to: ``'coffee'``
**COFFEE_PREPROCESS**
If you want CoffeeScript files to be compiled when ``app.debug`` is
``True`` and compressed files are not being used.
Defaults to: ``True``
**AUTOPREFIXER_BIN**
If you want to use `Autoprefixer`_ you must point this to ``autoprefixer``.
Defaults to: ``'autoprefixer'``
**AUTOPREFIXER_ENABLED**
Flag to indicated whether to run Autoprefixer on bundles and preprocessed
files.
Defaults to: ``False``
**AUTOPREFIXER_BROWSERS**
Determines which browsers to prefix for. See `Autoprefixer`_ documentation
for more information.
Defaults to: ``'last 2 versions'``
**UGLIFY_BIN**
If you want to use `UglifyJS`_ you must set this variable.
*It has no default value.*
**CLEANCSS_BIN**
If you want to use `clean-css`_ you must set this variable.
*It has no default value.*
**FUNNEL_USE_S3**
If you are using `Flask-S3`_ you must set this to use Flask-S3's
``url_for()`` function.
Defaults to: ``False``
Including bundles in templates
==============================
To include a bundle in a template you can use the ``css()`` or ``js()``
function:
.. code-block:: html+jinja
{# Jinja2 template #}
<!doctype html>
<html>
<head>
<title>The Title</title>
{{ css('bundle-name') }}
</head>
<body>
<h1>Headline</h1>
{{ js('bundle-name') }}
</body>
</html>
This will generate the appropriate markup for each bundle.
Note: When ``app.debug`` is ``True`` these will output markup for each file in
the bundle.
Media types for stylesheets
---------------------------
The ``css()`` function will, by default, generate ``<link>`` tags with a
``media`` attribute set to ``CSS_MEDIA_DEFAULT``. You can override this by
passing an optional second argument.
Using the manager to bundle and minify assets
---------------------------------------------
The extension provides a sub-manager for `Flask-Script`_ which can be used as
follows:
.. code-block:: python
from flask.ext.script import Manager
from flask.ext.funnel.manager import manager as funnel_manager
manager = Manager(app)
manager.add_command('funnel', funnel_manager)
You can now use the manager to bundle and minify your assets using::
$ ./manage.py funnel bundle_assets
This will create a ``bundle`` folder within the app's static folder to store the
bundled files. CSS bundles go into a ``css`` subfolder and JavaScript bundles go
into the ``js`` subfolder. Each of these subfolders will have a number of
``*-min.*`` files which are the compressed and minified versions of the bundles.
