FeatureToggles

This gem provides a mechanism for pending features that take longer than a single release cycle. The basic idea is to have a configuration file that defines a bunch of toggles for various features you have pending. The running application then uses these toggles in order to decide whether or not to show the new feature.

Installation

Add this line to your application's Gemfile:

gem 'feature_toggles'

And then execute:

$ bundle

Or install it yourself as:

$ gem install feature_toggles

Usage

features = FeatureToggles.build do
  # define env var prefix to enable features
  # globally by passing MY_PREFIX_BAR=1
  env "MY_PREFIX"

  feature :bar do
    user.can_bar?
  end

  feature :foo do |user: nil|
    !user.nil? && user.can_foo?
  end
end

features.enabled?(:bar)
features.enabled?(:bar, user: user)
features.for(user: user).enabled?(:foo)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also 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, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
