mpatch

Monkey patch collection for advance helper functions

This project aim to give flexible methods to the developer by giving new methods by inheritance to the base classes. This will result in lot of helper methods, and metaprograming tricks

Install

gem install mpatch

Use

    # load and patch all
    require 'mpatch'

example with Class methods

    require 'mpatch'

    class Test2
      @@test= "asd"
    end

    class Test < Test2

      def initialize

        @hello= "world"
        @no   = "yes"

      end

    end

    puts Test2.inherited_by.inspect
    # [Test]

    puts Test.conv2hash
    # {"test"=>"asd"}

    puts Test.new.conv2hash
    # {"hello"=>"world", "no"=>"yes"}

The module give you tools in your hand for inheritance handle. For example:

    puts Models::MongoidClassName.mixin_ancestors.include? Mongoid::Document
    #> true

    puts Mongoid::Document.inherited_by.inspect
    #> [MongoidClassName]

    class Test

    end

    module Hello
      class World < Test
      end
    end

    puts Test.inherited_by.inspect
    #> [Hello::World]

    module ParentModule

    end

    module TargetModule
      include ParentModule
    end

    module SomeModuleThatInclude
      include TargetModule
    end

    class SomeClassThatInclude
      include TargetModule
    end

    puts TargetModule.inherited_by.inspect
    #>[SomeClassThatInclude, SomeModuleThatInclude]

    puts TargetModule.inherited_by(Class).inspect
    #>[SomeClassThatInclude]

require for use only

    require File.join 'mpatch','array' # == require 'mpatch/array' but works on windows alike

    # sugar syntax
    # in this case it will help you with Array class for the following
    #
    #   Array.__send__ :include/:extend , ::MPatch::Module::Name
    #
    # it will always choose include or extend method based on the module use porpuse
    # now it's a :include

    MPatch.patch! # || inject_patches || inject
    puts ["asd"].has_any_of?(%W[ 123 hello\ world sup? asd ])

make your own!

you can make your own monkey patches by the following

  module MPatch

    module Include # if you want to include to the target object

      module TargetClassName #> for example Array

      end

    end

  end

  MPatch.patch!
  # done, you all set
  # if you want to contribute with use cases, please do so! :)

Fun with access rights

you can make an object / class / module instance or self methods private even from an instance

    # this is used for make private methods in an object
    # you can also use this to convert already defined methods in an object or class
    # use:
    #
    #   privatize in: 'hello_world'         #> make hello world method private in the self obj
    #
    #   privatize target: 'instance'        #> you can use this in a class to make instance methods private
    #   privatize target: 'singleton'       #> you can use this in a class to make self methods private
    #
    #   privatize ex: Symbol/String/Array   #> you can use this for make exceptions what should be not touched in the prcs
    #   privatize in: Symbol/String/Array   #> you can use this for make targeted collection of methods for privatize
    #

    class Test

      def say
        "hello world"
      end

      def sup
        "fine thx"
      end

      privatize t: :instance, ex: 'sup'

    end

    test1= Test.new

    puts test1.sup #> fine thx

    puts try{ test1.say } #> will fail and say error instead "hello world"
    puts test1.__send__ :say #> hello world

    test1.privatize only: 'sup'
    puts try{ test1.sup } #> fail again because it's private

After words

But there is a lot of method, for example for modules modules / subbmodules call that retunr modules under that namespace. Lot of metaprogrammer stuff there too :)

please do enjoy :)
