# Experiment::Light

Turn features on or off in various rails environments

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'experiment_light'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install experiment_light

## Usage

Run install generator:

    $ rails generate experiment_light:install

A yaml file named `experiment.yml` will be added into `config/` after running install generator, now your can define your experimental features:

    foo:
        development: true
        test: true
        production: false

    bar:
        development: false
        test: true
        production: false

Now you can use it in models like this:

    class TestModel < ActiveRecord::Base
      ...

      if experiment_on?(:foo)
        def foo_method
          ...
        end
      end

      ...
    end

In controllers like this:

    class TestController < ApplicationController
      ...

      def index
        ...

        if experiment_on?(:foo)
          redirect_to :back
        end

        ...
      end

      ...
    end

And in views like this:

    <% if experiment_on?(:foo) %>
        <p>Experiment foo is on</p>
    <% end %>

    <% if experiment_off?(:bar) %>
        <p>Experiment bar is off</p>
    <% end %>
