Don't take all this badly Ugo: I see much more dangers in turning the sitemap into a scripting language than the advantages brought by saving a few keystokes or the ease of implementation. But I'm all for a simplified implementation of the current syntax. Something that once came to my mind as a possible way to implement the sitemap engine (and also JXTG) is Jelly, provided by the same James Strachan that made Groovy after he came to dislike pointy brackets.
I'm not taking this badly at all, Sylvain :-) I am perfectly aware of the risks involved in such an attempt. Indeed I wrote (and you quoted): "I have to admit I'm ashamed at how bad and simpleminded the implementation of this is (you can find it in Butterfly's CVS). And propbably using a full-fledged scripting language isn't such a good idea (I already see people putting database access code in the sitemap)".
One of the reasons I came up with this "design" is that I'm trying to adopt a "tracer bullet" type of approach (if you haven't read Hunt and Thomas' "The Pragmatic Programmer" I suggest that you grab a copy and read it, it's highly recommended, or else you can find a description here [1]). So I needed something that could enable me to reach very rapidly the target of having an actual program that would be able to take an HTTP request, feed it to a sitemap that is (semantically if not syntactically) equivalent to a subset of the Cocoon sitemap and send out an appropriate response.
I'm cutting short on this since I'm writing from the hall of my hotel (thanks to WiFi) and I should actually be already at my customers', but I think I got great feedback from you and from all the other people who participated in this thread. Starting tomorrow, I'll be on vacation for one week, but fully connected, so I hope to find the time and the clarity of mind to come up with something less dumb and simpleminded. Stay tuned!
