irb.tools

Improvements for Ruby's IRB console, like colored output and a lot of debugging and introspection methods. Unlike with PRY, you are still in your normal IRB. It is designed to work out-of-the-box, so there is no reason to not use it! View demo!

Setup

Add to your project's Gemfile

gem 'irbtools', require: 'irbtools/binding'

Add to ~/.irbrc

require 'irbtools'

Usage

Put binding.irb in your code to start a new IRB session. Then try the following things in your enhanced IRB:

• code :ls # list the source of a Ruby method
• vim # starts VIM inside your IRB to edit multi-line code
• copy "string" # copy something to your system clipboard
• mf [1,2,3], [3,2,1] # list methods that transform object1 into object2
• ls # list current directory contents
• ~cd # change current directory to home directory
• rq:mathn # short way of saying: require 'mathn'
• mof [1,2,3] # list methods for each module the object inherits from
• howtocall Open3, :popen3 # print method signature
• re "mail@janlelis.de", /\b([A-Z0-9._%+-]+)@([A-Z0-9.-]+\.[A-Z]{2,10})\b/i, 0..2 # visualize a regex
• self.instance.set :a, 42 # simple way to manipulate instance variables

There is a lot more. See the ReadMe file for further documentation!
