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)
