FunctionModule

Ruby's module functions are really a combination of private method and public singleton method. This gem offers some utility methods for manipulating module functions.

Installation

Add this line to your application's Gemfile:

gem 'function_module'

And then execute:

$ bundle

Or install it yourself as:

$ gem install function_module

Usage

Module#module_functions (public)

Returns Array of Symbol with names of module functions (both private instance method and public singleton method are defined).

Note:

• It doesn't check method definition; even if private instance method and public singleton method are different, it is counted as module function.
• methods in Module itself are excluded (Module.new.module_functions return empty Aryay)

Module#include_module_functions(mod) (private)

Using include_module_functions another_mod in some module,

• include another_mod as usual.
• extend another_mod and make module functions public (usable for singleton methods)

Module#alias_module_function(new_name, old_name) (private)

Make alias of module functions. In alias/alias_method, only instance method is aliased.

Development
