Instance Method Details

#compass ⇒ Object

Adds compass configuration accessor to the application configuration.

If a configuration file for compass exists, it will be read in and the project’s configuration values will already be set on the config object.

For example:

module MyApp
  class Application < Rails::Application
     config.compass.line_comments = !Rails.env.production?
     config.compass.fonts_dir = "app/assets/fonts"
  end
end

It is suggested that you create a compass configuration file if you want a quicker boot time when using the compass command line tool.

For more information on available configuration options see: compass-style.org/help/tutorials/configuration-reference/
