ActiveNothing

A ruby gem inspired by a talk from Sandi Metz and Yehuda Katz blogpost for better flow of conditions.

Installation

Add this line to your application's Gemfile:

gem 'active_nothing'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_nothing

Usage

After doing:

require 'active_nothing'

You now have an access to inverse conditional flow like:

[true, false, nil, Object, 0, 1, "", [1, 2, 3], {}].each do |value|
  value
    .if_true  { p "#{value} is truthy" }
    .if_false { p "#{value} is falsey" }
end

You can use it as you wish.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
