Trace the whole chain of method calls.

Installation

Add this line to your application's Gemfile:

gem 'trace_calls'

And then execute:

$ bundle

Or install it yourself as:

$ gem install trace_calls

Usage

require 'open-uri'
require 'trace_calls'

TraceCalls::on do
  open('http://google.com', proxy: nil)
end

puts TraceCalls::root
