Chirrin Chirrion

Chirrin Chirrion is a gem to manage feature toggle, allowing developers to easily change the software behavior by showing/hiding new features and fixes.

Inspiration

The gem name was inspired by a funny Chapolim Colorado episode called 'Chirrin Chirrion del Diablo', where there was a magic wand that created new things if its bearer used the magic word 'chirrin', and those things were destroyed with the word 'chirrion'.

Install

gem install chirrin-chirrion

How to use

Configuration

require 'chirrin-chirrion'
redis_connection = Redis.new

# => [#<OpenStruct description="What the toggle does.", active=true, name="toggle_name">]
