Method: Bundler::Thor::Base#initialize

Defined in:
lib/bundler/vendor/thor/lib/thor/base.rb

#initialize(args = [], local_options = {}, config = {}) ⇒ Object

It receives arguments in an Array and two hashes, one for options and other for configuration.

Notice that it does not check if all required arguments were supplied. It should be done by the parser.

Parameters

args<Array>

An array of objects. The objects are applied to their respective accessors declared with argument.

options<Hash>

An options hash that will be available as self.options. The hash given is converted to a hash with indifferent access, magic predicates (options.skip?) and then frozen.

config<Hash>

Configuration for this Bundler::Thor class.
