Overview

A hash with indifferent access and magic predicates.

hash = Bundler::Thor::CoreExt::HashWithIndifferentAccess.new 'foo' => 'bar', 'baz' => 'bee', 'force' => true

hash[:foo]  #=> 'bar'
hash['foo'] #=> 'bar'
hash.foo?   #=> true

Dynamic Method Handling

  

    This class handles dynamic methods through the method_missing method




  

    #method_missing(method, *args)   (protected)
  



  

    

Magic predicates. For instance:



options.force?                  # => !!options['force']
options.shebang                 # => "/usr/lib/local/ruby"
options.test_framework?(:rspec) # => options[:test_framework] == :rspec

def method_missing(method, *args)
  method = method.to_s

    if args.empty?
      !!self[$1]
