I am evaluating a few template engines for a non-web based java processing program. There are so many available that I woould like to see what's your experience if using the template engines.
I liked Rythm (http://rythmengine.org/doc/feature#rich-function) but dont know if any large application have been using this successfully. Velocity was good when I used it more than 10 years back. But is it in active development any more? The last news I see in Apache Velocity home page is from 2010. What other ones would you recommend me to check considering I dont need any "View" layer at all for this? Its all macro based replacement of content.
