java - Concatenating a variable with other text using Rythm -

i using rythm templating engine. have variable , want 'concatenate' other text without spaces. don't know how delimit variable name , surrounding text - rythm tries resolve both variable name , text single expression.

here example:

@args string hello @whoextra 

i following error when trying on http://fiddle.rythmengine.org:

org.rythmengine.exception.compileexception: whoextra cannot resolved variable 

if 'who' has value 'world', want print is:

hello worldextra 

i can achieve with:

@args string hello @who.raw()extra 

but seems bit verbose, if use in many places.

is there better way delimit expressions in rythm?

use ( , ) separate:

@args string hello @(who)extra
