override-parens

override-parens

A few gems and Ruby libraries - notably the JSON library that comes with Ruby - give you shorthands like the following:

JSON('{}') == JSON.parse('{}')

Ruby doesn't actually let you override the method call operator - what's really going on is that the JSON library defines a method JSON on Kernel, and Ruby tolerates methods that have the same name as a class or module.

This gem lets you hide that piece of trickery and pretend that it's possible to override parentheses in Ruby.

require 'override-parens'

class MyClass
  include OverrideParens

  def self.parens(foo)
    new(foo)
  end

  def initialize(foo)
    @foo = foo
  end
end

MyClass(1)
