Re: [xwiki-users] How end user can capitalize on groovy/velocity fscript in xwiki?

Hi, I think of Velocity as a templating language. You can write: {{velocity}} Your username is $xcontext.getUser(), welcome to the site. {{/velocity}} Combining code and text in a natural way. You can even include XWiki markup in your velocity script since the output from velocity will go to the rendering engine. In groovy the same example would look like this: {{groovy}} println("Your username is " + xcontext.getUser() + " welcome to the site."); {{/groovy}} Also possible but not as easy. We usually use velocity for everything unless there is a compelling reason for groovy (there are some things such as the import keyword which are not available in velocity) Caleb On 05/18/2012 04:31 AM, mohit gupta wrote: > Hi all, > > i have seen xwiki can do lot of stuff with groovy and velocity.I am new to > groovy so trying to understand how groovy and velocty can benefit xwiki and > ultimately end user.

Right?
