# Dead simple configuration

Read configuration from a YAML/JSON file and expose the keys as methods.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'dsc'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install dsc

## Usage

Create a config file (you can use ERB):

```yaml
development:
  username: dev
  password:
production:
  username: hugo
  password: secret
  pool: 42
  url: <%= ENV["DATABASE_URL"] %>
```

Open the file and use it:

```ruby
require 'dsc'

database_config = Dsc.load_file('config/database.yml', env: 'production')
database_config.username # => 'hugo'
database_config.url      # => 'adapter://hostname:4567/database'
```

That's it!

### Optional attributes

If you want to be able to not specify some of the configuration options:

```ruby
config = Dsc.load_file('config/config.yml', env: 'production', optional: [:pool, :password])
```
