I think that might be overkill.
This is the same reason people write their own crappy templating systems. “I just need to do this one little thing and that whole template engine looks so intimidating, I’ll just write a few lines of code to do this myself.” Of course they end up expending extra effort to deal with the absence of various conveniences of a full-featured system, and the five-line solution inevitably grows until it has 1/3rd the features of a full-featured system except that the in-house solution is an organically grown mudball rather than a coherently designed whole. It’s OK, mind, to write your own templating system. Or meta object library. Or web framework. Or whatever. Just be sure you want to. Especially if your goal is to put it into production, you need be aware of the scope of the problem ahead of time; if you resolve to do a thorough job and understand what you are committing to, go ahead. OTOH if you want to experiment and you don’t have any plans to inflict your creation on production code then that’s great too: learning by doing provides the deepest understanding. But “$system/$library/$framework intimidates me” is not a valid reason to do a zero-effort hack. Regards, -- Aristotle Pagaltzis // <http://plasmasturm.org/>
