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:

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

and run:

```console
$ bundle install
```

If you are not using Bundler:

```console
$ gem install config_yml
```

then in your Ruby code:

```ruby
require "configuration"
```

Examples
--------

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

```ruby
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:

```ruby
redis = Conf.redis
```

#### Environment based:

```yaml
# 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

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

Rails

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


#### Nested:

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

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