Comments on: Filters 0.1 Released http://www.thesamet.com/blog/2006/12/07/filters-01-released/ The Ramblings of a Freelance Software Developer Sun, 06 Jul 2008 02:19:39 +0000 http://wordpress.org/?v=2.5.1 By: Ben Bangert http://www.thesamet.com/blog/2006/12/07/filters-01-released/#comment-973 Ben Bangert Thu, 21 Dec 2006 00:20:32 +0000 http://www.thesamet.com/blog/2006/12/07/filters-01-released/#comment-973 Myghty has had filters since its inception as well, which essentially just need to take an argument and return. The function style for a filter seems universal enough that there's little reason I can see for filters to be bound to a specific template language. Of course, I'm somewhat curious when one would decide that something should be used as a filter vs a normal function call. In Django for example, they *have* to use filters for a lot of those since they can't just call Python functions (the template language won't allow normal function calls). So what they would have to write as {{ file_size | tg.filesizeformat() }} you could write in Kid as ${ tg.filesizeformat(file_size)}. If you have something you need to format 3 times, it definitely makes more sense to use a filter style than wrapping all those functions. Maybe someone else has some good set of guidelines for when you'd use one instead of the other?

It makes sense to add a convenience decorator that does both. Alastir, you could be right. It makes sense to add a convenience decorator that does both.

Aren't we always going to write both of them? Put another way, is there a use for writing just one of the decorators and not the other? Why have two decorators rather than one?
