  • At least, the two places I've worked at that used TT (Socialtext and LiveText) both had gobs and gobs of logic in the templates. And TT's crippled language made dealing with this much harder than dealing with the same thing in Mason, since at least with Perl you have a sane language to use.

    People keep saying TT helps with this problem, but I have yet to see a good example of using it cleanly.

    • Re: (Score:2, Insightful)

      I agree that there are people who abuse TT by putting application logic in templates. But given enough rope, there will always some people who end up hanging themselves, or at best, tripping themselves up.

      TT's language is deliberately "crippled" because it's a presentation language, not a programming language. And the fact that TT makes it so trivially easy to write and use a plugin means that no-one should ever be doing "programming" using TT.

      But they do :-(

      However, that fact that some people don'

      • I think the TT has the fault lines at all the wrong places. Templates have three classes of complexity: static text (obviously a large part of the output); simple interpolation and undemanding logic (loops, conditionals; very common as well); and then hairy complicated formatting stuff with lots of little conditionals and munging and all sorts of wiry bits poking out of the data (common, but only in small amounts). The TT language is far more powerful than necessary for the simple logic but not enough to ha

        • Display logic needs the same facilities for abstraction as business logic.

          Some days, it seems that only four people in the world understand this. (The third is Avi Bryant.)

      • I am convinced there's no such thing as a perfect separation of application and presentation logic.

        That said, we've done quite well with TT in Slash over the years.
