## ConfigFun:  Beautiful configurations for your projects and gems

http://github.com/gammons/config_fun

## DESCRIPTION:

Does your gem or project need the user to create or add configuration to it?  Use ConfigFun to allow them to easily configure your gem, in a quick, terse and painless way!

## SYNOPSIS:

Adding ConfigFun to your project is super easy.  Include the config_fun gem as part of your gem's dependencies.  

Say you need to write a configuration that allows the user to add their account information, name, password, and some IMAP information.
With ConfigFun, the configuration could look like this:

```ruby
account "personal" do
  name "grant"
  password "bungalow"

  imap do
    server "imap.gmail.com"
    ssl true
  end
end
```

To parse this configuration, you'd simply Say the following:

```ruby
config = ConfigFun.parse!(File.read(account_information_file))
```

..and the config variable would include a sweet hash of all the info the user provided!

```ruby
config == {:account=> {:password => "bungalow", :imap => {:ssl => true, :server => "imap.gmail.com"}, :name => "grant"}}
```

## DETAILS:


### Arrays

if ConfigFun encounters a block twice within the same context, it will create an array.

```ruby
user do
  room "123"
end

user do
  room "456"
end
```

The resulting hash will have a `:user` key with an array of `:room`s as the value.

```ruby
{:user=>[{:room=>"123"}, {:room=>"456"}]}
```

### An important caveat

Blocks do not take any paramters.  You may be tempted to do something like the following:

```ruby
user "Bob" do
  room "123"
end
```

ConfigFun <strong>will not</strong> be able to parse this, because there is no equivalent hash it can boil down to.

The correct way to write the above code for ConfigFun is as follows:

```ruby
user do
  name "bob"
  room "123"
end
```
