SystemNavigation

• Repository: https://github.com/kyrylo/system_navigation/

Description

SystemNavigation is a Ruby library that provides support for the navigation and introspection of Ruby programs. It is inspired by the eponymous class in Pharo/Squeak.

Sneak peek:

module M
  def increment
    @num + 1
  end
end

class A
  include M

  attr_reader :num

  def initialize(num)
    @num = num
  end
end

sn = SystemNavigation.default

sn.all_accesses(to: :@num, from: A)
#=> [#<UnboundMethod: A#num>, #<UnboundMethod: A(M)#increment>, #<UnboundMethod: A#initialize>]

And many more...

Installation

All you need is to install the gem.
