GemConfigurator

Provides a simple, uniform way to configure a gem with a yaml file. Designed to work within a Rails app.

Add this line to your application's Gemfile:

gem 'gem_configurator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gem_configurator

Include the module into a class that you wish to configure via YAML.

  class Foo
    include GemConfigurator
    
    def initialize()
      configure
      ...
    end
    
    ...
  end

Within your rails app, place a config file in the /config directory. The config file's name must match the class's name. For example, to configure Foo, name the file foo.yml.

Example yaml file:

  development:
    [setting name]: [setting value]
    ...
  
  test: 
    ...

On instantiation, the settings for your current environment are placed in an instance variable called @settings. Retrieve the settings with @settings['setting name']

If you want to use symbol keys for your settings, change your yaml file to this:

  development:
    :[setting name]: [setting value]
    ...  

Then retrieve the setting with @settings[:setting name]

The gem parses ERB, so if you're storing configuration settings in environment variables, this works:

  development:
    redis_uri: <%= ENV['redis_uri'] %>

If you want your object to have default settings, simply define a default_settings instance method.

  class Foo
    include GemConfigurator
    
    def initialize()
      configure
      ...
    end
    
    def default_settings
      {:setting_name => setting_value}
    end

Default settings will be merged with any settings defined in the YAML file. YAML file settings will overwrite a default setting of the same name.
