Octopress Asset Pipeline

Combine and compress and fingerprint Stylesheets (CSS and Sass) and Javascripts (JS and Coffeescript) to a single fingerprinted .css or .js file.

How it works: This plugin will automatically read .js, .coffee, .css, .scss and .sass files from your site, combine, compress and fingerprint them so they're ready for deployment. Then add the liquid tags to your site layout to write the necessary script or link tags.

Installation

Using Bundler

Add this gem to your site's Gemfile in the :jekyll_plugins group:

group :jekyll_plugins do
  gem 'octopress-asset-pipeline'
end

Then install the gem with Bundler

$ bundle

Manual Installation

$ gem install octopress-asset-pipeline

Then add the gem to your Jekyll configuration.

gems:
  -octopress-asset-pipeline

Basic usage

This should be very simple to use.

1. Add Sass or CSS to stylesheets/ or css/ directory in your site's source.
2. Add Coffeescript or JS to stylesheets/ or css/ directory in your site's source.
3. Put Coffeescript and JS in [source]/javascripts/.
4. Add liquid tags (see below) to your sites layout.
5. Build.

If you want, you can configure which directories this plugin reads from. See the configuration section below.

Liquid tags

Include these tags in your site's layout.

{% css_asset_tag %}
{% js_asset_tag %}

When Jekyll builds your site, these will be replaced with something like this.

<link href='/stylesheets/all-b5c56f2652600cde201589531c453ba1.css' media='all' rel='stylesheet' type='text/css'>
<script src='/javascripts/all-75489c7b2da6efce7ee1bc45795d400b.js'></script>

Configuration

This plugin integrates with the core asset pipeline system in Octopress Ink, therefore the configurations are set in the _config.yml configuration file under the asset_pipeline key.

Option	Description	Default
stylesheets_dir	Directory to read stylesheets from	['css', 'stylesheets']
javascripts_dir	Directory to read javascripts from	['js', 'javascripts']
combine_css	Combine all .css, .scss and .sass files	true
combine_js	Combine all .js and .coffee files	true
compress_css	Compress stylesheets for production	true
compress_js	Compress Javascripts for production	true
order_js	Order for .js and .coffee files	[]
order_css	Order for .css, .scss, and .sass	[]
uglifier	Settings for Javascript Uglifier. Documentaion.	{}

Ordering assets

By default when scripts and stylesheets are combined, they are added based on their order in the file system. You can manually specify order like this:

asset_pipeline:
  order_js:
   - jquery.js
   - kittens.coffee

  order_css:
   - normalize.css
   - site.sass

Assets will ordered as specified. Any additional assets will be appended based on their order in the file system.

Note: It is not necessary to write full paths in these configurations. An asset at javascripts/lib/jquery.js will match jquery.js and be ordered accordingly.

Media files

Usually it's better to define print styles inside of the main CSS file beneath a print media query, like this.

@media print {
  * { background: none }
  * { color: #000 }
  ...
}

If you want to specify a separate print stylesheet, include @print in your filename, before the extension.

When your site is compiled, this file will be written separately and its <link> tag will include a media='print' attribute.
