Sprites is a library that let's you define the sprites for your application with configuration or convention. Sprites will generate your sprites, and a corresponding stylesheet for each using either the cli or from within a Rails application.

sprite :bas

sprite :buttons, :path => "buttons.png", :stylesheet_path => "buttons.css", :autoload => false do
  sprite_piece 'buttons/btn-black-default-28.png', 'a.black.button > span, button.black.submit span'
  sprite_piece 'buttons/btn-black-default-cap-28.png', 'a.black.button, button.black.submit', :x => 'right'
  ...
end

            \_green_icon.png

gem install sprites

execute:

cd PROJECT_ROOT
sprites

For usage

sprites --help

gem 'sprites'

config.uses_sprites = true

Optionally include a config/sprites.rb (see above). Otherwise Sprites will use it's auto-load feature. Example, if you have app/assets/images/sprite_images/foo/bar.png and app/assets/images/sprite_images/foo/bas.png, Sprites will create app/assets/stylesheets/sprites/foo.css and app/assets/images/sprites/foo.png. The class for bar.png will be .bar and for bas.png, .bas, etc.

rake sprites

to generate.

module MyGem
  class Engine < Rails::Engine
    config.uses_sprites = true
  end
end

Use app/assets in your gem like you would your rails app and use the asset pipeline.

From your rails root

ENGINES=true rake sprites

Note: this will generate your sprites for your Sprites enabled Engines and your Sprites enabled Rails app.
