module_chain_method

Module::ChainMethod mixin to simplify method chain aliasing.

Example

require 'module/chain_method' # Module::ChainMethod

module MyMixin
def self.included target
  super
  $stderr.puts "MyMixin.included #{target}
end		 
include ::Module::ChainMethod

def foo
  puts "MyMixin#foo"
  foo_without_MyMixin
end

def bar
  puts "MyMixin#bar"
end

# Prepares method #foo for chaining.
chain_method :foo
end
  
class Foo
def foo
  puts "Foo#foo"
end
    
def bar
  puts "Foo#bar"
  super rescue nil
end
end

f = Foo.new
f.foo
f.bar
puts

Foo.send(:include, MyMixin)
f.foo
f.bar

Generates the following output:

ruby -I lib example/ex01.rb Foo#foo

Foo#bar

MyMixin.included Foo
MyMixin#foo
Foo#foo
Foo#bar
MyMixin#bar

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
