Introducing the Carbolic gem v0.3

The Carbolic gem is used for tracing the instruction path of your gem after it is exectuted. It's intended to make debugging easier especially when your code raises an error and it's location in the code isn't convenient to track down.

require 'carbolic'

class Welcome
  def initialize()
    super()
    @user = 'guest'
  end

  def fun(name)
    puts 'hello ' + name
    authorised? ? true : false
  end

  def authorised?()
    @user == 'admin'
  end
end

Carbolic.log('/home/james/learning/ruby/temp/rexle.log') do |x| 
  x.trace('Welcome')
end

welcome = Welcome.new
welcome.fun 'JR'  

Output

There are 3 fil es created, which are:

We are only interested in the rexle.log which is shown below:
