Decided to completely rewrite one of their modules for DLE and it just so happened that I did not fit (and not like) standard DLEшный the engine lacks the opportunity. The module is intended for custom display news, will be very many different options for the output settings, which is the default template engine will be a lot of problems and most likely brakes.
So I look to the side 3 RainTPL
Both of the templating engine, in principle, similar for writing variables to an ordinary mortal (for the user who installed the module on your site and customized a template to suit yourself).
I personally like RainTPL, but with Smarty, I did not work, so I want to hear the opinion of experienced colleagues dealing with these template engines. It may have any obvious advantages one of them compared to others? Or overt schools?
