How it works

See the lemonade descriptions Show archive.org snapshot .

Unfortunately, the gem has a few problems:

• it does not work with Sass2
• it always generates all sprites when the sass file changes, which is too slow for big projects
• it expects a folder structure quite different to our usual

All these problems are solved for us, in our own lemonade fork Show archive.org snapshot . This fork has since been merged to the original gem, maybe we can use that one now too.

Installation

• gem install compass -v=0.10.2

• gem install chunky_png -v=0.8.0

• freeze our lemonade version

  • cd vendor/gems
  • git clone http://github.com/makandra/lemonade.git lemonade-0.3.4
  • rm -rf lemonade-0.3.4/.git

• in config/environment.rb:

  • config.gem 'compass', :version => '=0.10.2'
  • config.gem 'lemonade', :version => '=0.3.4'
  • config.gem 'chunky_png', :version => '=0.8.0'

• create config/initializers/compass.rb (or copy from development repo):
  ^
  require 'compass'
  rails_root = (defined?(Rails) ? Rails.root : RAILS_ROOT).to_s
  Compass.add_project_configuration(File.join(rails_root, "config", "compass.rb"))
  Compass.configure_sass_plugin!
  Compass.handle_configuration_change!

• create config/compass.rb (or copy from development repo):
  ^

  This configuration file works with both the Compass command line tool and within Rails.

  Require any additional compass plugins here.

  project_type = :rails
  project_path = Compass::AppIntegration::Rails.root

  Set this to the root of your project when deployed:

  http_path = "/"`
  css_dir = "public/stylesheets"
  sass_dir = "public/stylesheets/sass"
  images_dir = "public/images"
  http_images_path = "../images"
  environment = Compass::AppIntegration::Rails.env

  To enable relative paths to assets via compass helper functions. Uncomment:

  relative_assets = true

  require 'lemonade'

• in .gitignore:
  ^
  *.sprite_info.yml`
  also

Remarks

This setup is still not optimal:

• dependency on compass is unnecessary
• installation a bit involved (maybe we can use the usual gem?)
