# Sweetloader

A 'sweet' autoloader that can autoload your modules and classes more easily, by taking advantage of a standard directory structure approach for the placement of your classes and modules. You can also configure Sweetloader to override the defaults in various ways... 

## Install

Insert in your Gemfile:

```ruby
gem 'sweetloader'
```

Run bundler to install

$bundle$

## Usage

Simply use the autoload_modules macro in your Module and Class definitions.

```ruby
CanTango
  autoload_module :Configuration, :Factory, :Permit
end
```

Each of these modules are then expected to be in @catango/configuration.rb@ and similar relative to a load path.

## Configuration

The following global config vars are available in AutoLoader:
* root
* namespaces

Set a specific root which the dir will be calculated relative to, using root.
Override namespace to directory auto-mapping using the namespaces hash.

```ruby
AutoLoader.root = ''
AutoLoader.namespaces= {:CanTango => 'cantango', :Permithelper => 'permit_helper'}
```

Normally the namespace/constant CanTango will be translated to the dir 'can_tango', here we override this so it will instead be translated to 'cantango'.

You can also specify these options directly as an option hash on the `#autoload_modules` call 

```ruby
  autoload_modules :Configuration, :Factory, :Permit, :root => 'helpers'
  autoload_modules :Configuration, :Factory, :Permit, :ns => {:CanTango => 'cantango'}
```

## Mutate path option

Can be used to execute more general substitution logic on the generated file path

```ruby
  autoload_modules :Configuration, :Factory, :Permit, :mutate_path => Proc.new {|path| path.sub(/(ies)/, 'y') }
```

## Scopes

```ruby
module AutoloadModules
  module Configuration
	# the scope options only have effect for autoload_modules statements within it!
    autoload_scope 
        :ns => { :AutoloadModules => 'fixtures/autoload_modulez'},
		:mutate_path => Proc.new {|path| path.sub(/(ies)/, 'y') } do
      autoload_modules :Admin
    end
    
    autoload_modules :Editor
  end
end
```

## Contributing to sweetloader
 
* Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
* Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
* Fork the project
* Start a feature/bugfix branch
* Commit and push until you are happy with your contribution
* Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
* Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
