How to integrate Compass with Rails 3.1 asset pipeline

readme.md

Compass is even easier to use in Rails 3.1

Compass Rails integration is trivial in rails 3.1. The "config/compass.rb" file is optional now.

During deploy run:

rake assets:precompile

Additional Upgrade instructions

1. Move your stylesheets from app/stylesheets or public/stylesheets/sass to app/assets/stylesheets.
2. Rename all non partials to *.css.s[ac]ss

Installing Compass Plugins

1. Gem based plugins: Add plugin to Gemfile

2. Archive based plugins: unpack the extension into vendor/plugins/compass_extensions

3. (optionally) Install the plugin templates. E.g.

   bundle exec compass install <plugin>
   

application.rb

if defined?(Bundler)
  Bundler.require *Rails.groups(:assets => %w(development test))
end

stylesheets_directory = "#{Rails.root}/app/assets/stylesheets"
config.assets.precompile += Dir.glob("#{stylesheets_directory}/**/*.s[ac]ss*").
                            map{|f| f[stylesheets_directory.size+1..-1]}.
                            select do |file|
                              if config.assets.precompile.include?(file)
                                false
                              elsif File.basename(file)[0...1] == "_"
                                false
                              else
                                true
                              end
                            end

# if you prefer `.sass` over `.scss`.
config.sass.preferred_syntax = :sass

Gemfile

group :assets do
  gem 'sass-rails', '~> 3.1.0'
  gem 'coffee-rails', '~> 3.1.0'
  gem 'uglifier'
  gem 'compass', '~> 0.12.alpha'
  # include other compass plugins here. E.g.:
  gem 'compass-susy-plugin', :require => 'susy'
end
