http://weitz.de/html-template/ Of course, it's made by the same guy as CL-WHO, which uses the s-expr system instead: http://weitz.de/cl-who/ > I am not talking about this particular application, but just in > general.

Mixed bag for me, though I pretty much agree. On the one hand, I prefer the terseness of s-exp templating, and that you can't forget to close a tag. On the other hand, my business partner isn't going to learn Lisp anytime soon and needs to be able to modify the HTML that gets output. I know technically Lisp is simpler than XML, but it's still intimidating to the muggles. :) The strength of something like PHP or embedded Ruby is that the text editors support it and you get the full power of the language inside the template. HTML-Template doesn't give you the full power of Lisp inside the template, but the advantage is that templates get compiled into something that executes really fast and it's easy enough that designers can probably handle it. I kind of hate seeing HTML being manually printed out deep inside the code. I'd rather pass s-exps out, or something. Better not to do any formatting deep in the code and have a real separation of concerns. It's also nice if you can change the way it renders without recompiling. HTML-Template, when you load a file, it keeps track of that file and if it changes out from underneath it, it notices and recompiles the template (rather like JSP, I guess). CL-WHO, you'd have to recompile the function somehow, which means you need to have a REPL open somewhere you can get to. Which probably isn't impossible but seems to be a little more involved with Clojure than it is with Lisp. Another point for external HTML-style templates. I've seen a couple templating systems (notably ZPT/TAL and Kid) that work by putting some XML from a different namespace into your document. Pro, your XML is always valid; con, it's a pain to work with and sometimes you just want to dump out some crap and don't really care if it's valid. Convenience versus correctness. I tend to side with convenience on templating. I dunno. This problem has a lot of solutions and all of them seem to involve compromises. — Daniel Lyons --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
