Module: Origen::CodeGenerators::Actions

Includes:
Helpers
Included in:
Base
Defined in:
lib/origen/code_generators/actions.rb

Overview

Common helpers available to all Origen code generators. Some of these have been copied from Rails and don’t make a lot of sense in an Origen context, however they are being kept around for now as they serve as good examples of how to write generator helpers.

#add_autoload(name, options = {}) ⇒ Object

Adds an autoload statement for the given resource name into app/lib/my_app_name.rb

An array of namespaces can optionally be supplied in the arguments. The name and namespaces should all be lower cased and underscored.

add_autoload "my_model", namespaces: ["my_namespace", "my_other_namespace"]

  in_root do
    prepend_file 'Gemfile', "source #{quote(source)}\n", verbose: false
  end
end

#camelcase(name) ⇒ Object

Equivalent to calling name.camelcase, but this will identify the need to register any acronyms necessary to ensure the camelcased name can be translated back to the original name by the underscore method. The required acronyms will be saved to an instance variable, @required_acronyms, and calling the add_acronyms will add the code to register them to the current application.
