Defined in:
lib/mack/assets/assets_mgr.rb

Overview

Like the name suggests, this object will manage assets (i.e. scripts and stylesheets) used in a mack application. Developer will be able to use the manager to create assets groups, and refer them later in the erb file.
There’s a convenient method available, called assets_mgr. Application should use that method to create new bundle, and to access defined bundles.
Example:

# This will create new bundle called foo
assets_mgr.foo do |a|
  a.add_js "foo"
  a.add_css "bar"
end

Note that nested group is not supported.
