Synopsis

An easy way to implement the facade pattern in your classes. In short, this library wraps singleton methods from another class as instance methods of the current class.

Installation

gem install facade

Adding the trusted cert

gem cert --add <(curl -Ls https://raw.githubusercontent.com/djberg96/facade/main/certs/djberg96_pub.pem)

Usage

require 'facade'

class MyString < String
  extend Facade
  facade Dir                       # extend all methods
  facade File, :dirname, :basename # extend only specified methods
end

f = MyString.new('/home/djberge')
puts f.basename # 'djberge'
puts f.dirname  # '/home'
