Example output

Features

  • Syntax highlighting for Ruby objects
  • No monkey patches anywhere
  • Support for generic objects, especially enumerators, and nested generic objects
  • Can be used without IRB
  • Supports stdlib objects, like Set
  • Custom color schemas via YAML

Install

Install the gem with:

$ gem install wirb

Usage

To start IRB with WIRB activated for one session, do:

$ irb -r wirb --inspect wirb

To activate WIRB permanently, you'll need to add this to the ~/.irbrc file:

require 'wirb'
Wirb.start

Bundled Schemas

These are the bundled color schemas. You can load one with Wirb.load_schema :name

  • :classic (default)
  • :colorless (only uses :bright, :underline and :inverse effect)
  • :ultra (matches the colorscheme from Ultra over in Clojure-land)

Usage with Rails

See the solution in this issue.

Kernel#wp

You can use WIRB like awesome_print to highlight any objects using wp:

require 'wirb/wp'
wp some_object
