RFC: How-To on subclassing Shared.DC.Scripts.Script.Script
I'm thinking here that subclassing Script is the way to go for any object that needs finer control on how it is called - and I'll say that of any class that doesn't just do index_html = HTMLFile(foo, globals()) So, I wrote a How-To. It's definitely not ready for prime-time, as I haven't actually used it to implement a class, but I think it's correct. I'd appreciate if people took a look at it and commented both on correctness and clarity/usefulness. It is at http://www.zope.org/Members/lalo/scriptclass-dev now; this is a ZWikiPage, so you can comment right there. The "real" address will be http://www.zope.org/Members/lalo/scriptclass when it's ready.

Mmmh, after reading the how-to (quickly), I do understand for what you are using Script for. But when I started reading it, I wanted to learn more of how I could implement a new scripting language into Zope, such as a ZOQL (as mentioned on the SmartObjects mailing list: http://imail.iuveno-net.de/pipermail/smartobjects/), Tcl, XQuery or XPath. Even though your usage of the Script-class is unique and obviously useful, I think you should make a note, that will not describe how to implement another scripting language. But other than that, I learned something new. Thanks for the tutorial.

Thank you :-) I don't think I could teach something as generic as this; the process would be completely different for each language, and depend on your interpreter. For starters, PythonScript and ZopePageTemplates are completely different. The classes to add new scripting languages would be similar up to the point I described in my How-To, I'm afraid. Up from there, it's you and your interpreter. []s, |alo +---- -- Esvazie sua mente, pequeno gafanhoto. Nós temos muito o que aprender... mas primeiro...
