GFreeMarker is an integration of the FreeMarker template engine for Groovy. It allows adding plugins written in Groovy for content rendering, making FreeMarker+Groovy just as easy as Smarty. This way of doing avoids security issues related to allowing direct Groovy scripting in templates. With GFreeMarker, you create plugins, and make it available to customers.

Imagine your customer requires an URL Encoding text transform, and that FreeMarker does not offer this transformation. Then, you would just need to :
That's all ! Now your customer can access it quite directly in the template. For example :
Here's a sample plugin which converts a string through URL encoder :
Here's a sample code which shows how easy it is to embed FreeMarker as a template engine for Groovy.
This code assumes a directory called plugins is in the working directory. The template engine will dynamically load the ''urlencoder'' class.
