Dipswitch

Super simple feature flag switcher.

Add this line to your application's Gemfile:

gem 'dipswitch'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dipswitch

Configure Dipswitch before calling it. In a Rails app you might want to do this in an initializer for example.

  Dipswitch.configure do |config|
    config.feature(:new_ui) do |user|
      user.admin?
    end

    config.feature(:beta) do |user|
      ['bella'].include?(user.username)
    end

    ## Or maybe for environment specific features

    config.feature(:enable_for_development) do |env|
      env == 'development'
    end
  end

In your application code ask Dipswitch if a feature is enabled:

  if Dipswitch.on?(:new_ui, current_user)
    # do stuff
  end

That's it.

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.
