Method: Rails::Command.find_by_namespace

Defined in:

railties/lib/rails/command.rb

.find_by_namespace(namespace, command_name = nil) ⇒ Object

Rails finds namespaces similar to Thor, it only adds one rule:

Command names must end with “_command.rb”. This is required because Rails looks in load paths and loads the command just before it’s going to be used.

find_by_namespace :webrat, :integration

Will search for the following commands:

"webrat", "webrat:integration", "rails:webrat", "rails:webrat:integration"

def find_by_namespace(namespace, command_name = nil) # :nodoc:
  lookups = [ namespace ]
  lookups << "#{namespace}:#{command_name}" if command_name
  lookups.concat lookups.map { |lookup| "rails:#{lookup}" }

  lookup(lookups)

  namespaces = subclasses.index_by(&:namespace)
  namespaces[(lookups & namespaces.keys).first]
