Guardfile

Guard::Sprockets can be adapted to all kind of projects.

Typical Rails 3 app (default generated Guardfile)

  watch 'app/assets/javascripts/application.js'
end

Please read Guard doc for more information about the Guardfile DSL.

Options

destination: 'public/js'          # change the destination folder in which the compiled assets are saved, default: 'public/javascripts'
asset_paths: 'app/js'             # add a directory (or on array of directories) to Sprockets' environment's load path, default: ['app/assets/javascripts']
asset_paths: ['app/js', 'lib/js'] # asset_paths can be a String or an Array
js_minify: true                   # minify the JavaScript files content using Uglifier. You can pass true, false, or an Uglifier options hash. default: false
                                  # be sure to add: "gem 'uglifier'" in your Gemfile
css_minify: true                  # minify the CSS files content using YUI Compressor, default: false
                                  # be sure to add: "gem 'yui-compressor'" in your Gemfile
keep_paths: true                  # retain the directory structure of an asset's path relative to the asset_path, default: false
                                  # this prevents assets with the same basename, but placed different folders, from overwriting each other in the destination folder
                                  # e.x. with this option set to true: app/js/vendor/rails/turbolinks.js.coffee -> public/js/vendor/rails/turbolinks.js
                                  # and with this option set to false: app/js/vendor/rails/turbolinks.js.coffee -> public/js/turbolinks.js
root_file: 'app/js/app.js'        # if set, only this file will be compiled, default: nil
root_file: ['one.js', 'two.js']   # root_file can be a String or an Array
