config_yml

Simplify your app configuration.

Description

config_yml provides a very simple way of configure your ruby applications through yaml files.

Installation

If you are using Bundler, add the following code to your Gemfile:

gem "config_yml", :require => "configuration"

and run:

$ bundle install

If you are not using Bundler:

$ gem install config_yml

then in your Ruby code:

require "configuration"

Usage

# config/redis.yml
password: foo
host: localhost
port: 6379
database: 1

if redis = Configuration.redis
  password = redis[:password] && ":#{redis[:password]}@"
  ENV["REDIS_URL"] = %(redis://#{password}#{redis[:host]}:#{redis[:port]}/#{redis[:database]})
end

ENV["REDIS_URL"] # => "redis://:foo@localhost:6379/1"

You can also use the shorthand:

redis = Conf.redis

Environment based:

# config/mysql.yml
development:
  adapter: mysql2
  encoding: utf8
  database: myapp_development
  username: foo
  password:
  socket: /tmp/mysql.sock

test:
  adapter: mysql2
  encoding: utf8
  database: myapp_test
  username: foo
  password:
  socket: /tmp/mysql.sock

Rack

ENV["RACK_ENV"] # => "development"
Configuration.mysql[:database] # => "myapp_development"

Rails

Rails.env # => "test"
Configuration.mysql[:database] # => "myapp_test"

Nested:

# config/matryoshka.yml
foo:
  bar:
    baz:
      array:
        - :red
        - :green
        - :blue

Configuration.matryoshka[:foo][:bar][:baz] # => { :array => [:red, :green, :blue] }

Manage yaml files

Avoid maintain .yml files in your repository since they very ofter cointain sensitive information. You can use .yml.sample or .yml.example file instead with fake data.

To transform sample files in yaml files, you can use the following task:

$ rake config_yml:generate

If you are not using Rails, first add this to your Rakefile:

require "configuration/tasks"
