module Rails
# Rails::Generator is a code generation platform tailored for the Rails
# web application framework. Generators are easily invoked within Rails
# applications to add and remove components such as models and controllers.
# New generators are easy to create and may be distributed as RubyGems,
# tarballs, or Rails plugins for inclusion system-wide, per-user,
# or per-application.
#
# For actual examples see the rails_generator/generators directory in the
# Rails source (or the +railties+ directory if you have frozen the Rails
# source in your application).
#
# Generators may subclass other generators to provide variations that
# require little or no new logic but replace the template files.
#
# For a RubyGem, put your generator class and templates in the +lib+
# directory. For a Rails plugin, make a +generators+ directory at the
# root of your plugin.
#
# The layout of generator files can be seen in the built-in
# +controller+ generator:
#
# generators/
# components/
# controller/
# controller_generator.rb
# templates/
# controller.rb
# functional_test.rb
# helper.rb
# view.html.erb
#
# The directory name (+controller+) matches the name of the generator file
# (controller_generator.rb) and class (ControllerGenerator). The files
# that will be copied or used as templates are stored in the +templates+
# directory.
#
# The filenames of the templates don't matter, but choose something that
# will be self-explanatory since you will be referencing these in the
# +manifest+ method inside your generator subclass.
#
#
module Generator
class GeneratorError < StandardError; end
class UsageError < GeneratorError; end
# The base code generator is bare-bones. It sets up the source and
# destination paths and tells the logger whether to keep its trap shut.
#
# It's useful for copying files such as stylesheets, images, or
# javascripts.
#
# For more comprehensive template-based passive code generation with
# arguments, you'll want Rails::Generator::NamedBase.
#
# Generators create a manifest of the actions they perform then hand
# the manifest to a command which replays the actions to do the heavy
# lifting (such as checking for existing files or creating directories
# if needed). Create, destroy, and list commands are included. Since a
# single manifest may be used by any command, creating new generators is
# as simple as writing some code templates and declaring what you'd like
# to do with them.
#
# The manifest method must be implemented by subclasses, returning a
# Rails::Generator::Manifest. The +record+ method is provided as a
# convenience for manifest creation. Example:
#
# class StylesheetGenerator < Rails::Generator::Base
# def manifest
# record do |m|
# m.directory('public/stylesheets')
# m.file('application.css', 'public/stylesheets/application.css')
# end
# end
# end
#
# See Rails::Generator::Commands::Create for a list of methods available
# to the manifest.
