 A ruby gem for parsing Wordpress style shortcodes. The gem uses a [PEG](http://en.wikipedia.org/wiki/Parsing_expression_grammar) (Parsing Expression Grammar) parser rather than using regular expressions so its easier to understand, test and extend.

 Sometimes the data passed to the template from the shortcode it not enough. Lets say you want to render a gallery of images using id numbers of images stored in a database, e.g. `[gallery ids="1,2,3,4"]`. This is where presenters can help, they allow you to modify the `@content` and `@attributes` variables before they are sent to the template for rendering. Presenters are simple classes that define four methods. The class method `for` should return the name of the shortcode (as a symbol) it should be applied to. The classes `initialize` method received the `attributes` and `content` variables. Finally the class should define `content` and `attributes` methods.
 
 In a rails app you could return image records to the template using something like this:
 
 ```ruby
-class CustomPrsenter
+class CustomPresenter
 
   def self.for
     :quote
   end

     end
 end
 ```
 
 #### Registering presenters
 
 To register a presenter simply call `Shortcode.register_presenter` passing the presenter class e.g.
 
 ```ruby
-Shortcode.register_presenter(CustomPrsenter)
+Shortcode.register_presenter(CustomPresenter)
 ```
