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
[ GitHub ]

  
# File 'lib/bundler/vendor/thor/lib/thor/core_ext/hash_with_indifferent_access.rb', line 89

def method_missing(method, *args)
  method = method.to_s
  if method =~ /^(\w+)\?$/
    if args.empty?
      !!self[$1]
    else
      self[$1] == args.first
    end
  else
    self[method]
