Ruby Object Inspection for IRB
WIRB Interactive Ruby 
The WIRB gem syntax highlights Ruby objects. Works best as your default REPL inspector (see usage section below), but does not require IRB.
Supported Rubies: 3.1, 2.7, 2.6
Older Rubies, should work: 2.5, 2.4, 2.3, 2.2, 2.1, 2.0, rubinius
Ancient Rubies (1.9, 1.8): Please use WIRB 1.0
Features
- Syntax highlighting for inspected Ruby objects
- No monkey patches anywhere
- Support for generic objects, especially enumerators, and nested generic objects
- Supports common standard library objects, like
Set - Color schemas customizable via YAML
Install
Install the gem with:
$ gem install wirb
Or add it to your Gemfile:
gem ‘wirb’
Usage
To start IRB with WIRB activated for one session, do:
$ irb -r wirb --inspect wirb
To activate WIRB permanently, you can add this to the ~/.irbrc file:
require 'wirb'
Wirb.start
Another way would be to use Irbtools, which activate WIRB automatically.
Kernel#wp
WIRB comes with a pretty printing utility (similar to awesome_print):
require 'wirb/wp'
wp some_object
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(by @venantius, matches the colorscheme from Ultra over in Clojure-land)
Usage with Rails
