  • Part of me wants to object, but part of me totally agrees.

    This is indeed why I'm pretty vocal against newbies creating their own templating language. They all start out "simple", and then slowly add variables (of course), and then decision and iteration. And once you have state/decision/iteration, you have turing completeness, and you start treating the templating language like a programming language, and it's all downhill from there.

    One of the things I like about Template Toolkit though is that it at le

    • Is really using something like TT2 for "programmy" things so wrong?

      I have abused TT2 to develop whole websites where there's a simple Apache module that can load the base template and pass it an object which can fetch records out of the database as hashes.

      The great thing about this is that people who don't think of themselves as being able to program are doing clever things with loops, and writing conditional logic. Of course you end up with something that might not be as neat as if it used a MVC architectu
      • Yes, it really is dangerous to write anything significant in the TT language. The problem is, as Fred pointed out, TT's language sucks at error messages and catching mistakes when compared to Perl. Perl gives good diagnostics, has a debugger and profiler, has strict and warnings, has perltidy, etc. TT has none of these things. Perl is also a lot more efficient in most cases.

        I think the TT language is great, as long as you stick to using it for templating tasks: put this here, loop through these. Any time I see someone trying to modify the data passed in to the template, or load data from the template, or do any kind of calculation in the template, I recommend that they either put that in the script that calls the template or encapsulate it in an object or plugin.
