[Michel] You've _really_ lost me, maybe someone else knows what you mean. I don't know what you mean by 'bind' (do you mean writing python extension modules in C?), or what Boost.Python is, or what you are referring to as 'Zope Python scripts' (do you mean the python modules that come with Zope?). [Albert] I don't know the answers to James' questions but here's the links for Boost Python: http://www.boost.org/libs/python/doc/index.html and comparison with Zope Extension Classes and other approaches: http://www.boost.org/libs/python/doc/comparisons.html Looks very interesting.

Re: [Zope-dev] Request for a Pluggin Index (NameIndex)
Looks like you should write your own index type. Zope 2.4 comes with an PlugableIndex interface to allow third-party indexes to be integrated into the Catalog.

Hi, If anyone's got the time or fancies a challenge, could they write an index that behaves as follows: Indexed values: 1) C.J.Withers 2) Chris Withers 3) C Petrilli 4) Christopher McDonough search result C 1,2,3,4 C.J.Withers1 c.j.Withers1 withers mcdonough 1,2,4 Chris 2,4 Christo4 I think the basic rules are: - split on whitespace and punctuation (not accentuated characters and the like ;-) - index each remaining name part - when searching, return all records where any of the name parts match something like: string.find(name_part,search_expression) ...oh yeah, and do it blindingly quickly ;-) This would be really useful for the Creator dublin core field and anywhere you're searching for someone's name.

[Zope-dev] [Announce] API Documentation Fishbowl Project
Fellow Zopistas, Mike Pelletier and I are working on a project to improve Zope's API documentation. Details are now publicly available in the fishbowl. (Actually it's been public for a while, but this is the first announcement of the project.) http://dev.zope.org/Wikis/DevSite/Projects/APIDocs I encourage you to check it out and leave your comments, criticisms, and suggestions. This project aims to improve the life of Zope developers, so please help us make sure we're not off base. For the project to succeed it must meet *your* needs.

We're currently using python 2.1 to run zope 2.3.2 with no ill effects. We have written our own product that uses some OFS stuff, Catalog and ZPT. Not much else...

Ah, will try that out :) And actually I directly found some method which fetches the actual user object from a ZPatterns rack and sets this in the REQUEST at every request.

[Zope-dev] SearchIndex: is this behaviour in 2.4?
Hi, sorry I can't test this myself. I get this behaviour in 2.3.2, and I find it strange. I'd classify it as a bug. If I pass this query to a TextIndex: (word1 OR word2) AND (word3) it is first translated to this: [['word1', 'or', 'word2'], 'and', ['word3']] which is fine. But then, after query_hook() in GlobbinLexicon.py: [['word1', 'or', 'word2'], ['word3']] and then the default_operator (Or) is used (by parse2()/query() in UnTextIndex.py, I think), and turns it into: [['word1', 'or', 'word2'], 'or', ['word3']] kinda not what I wanted. Since I always use parens around OR's I can just set the default_operator to And and this solves my problem, but it's still not working correctly. Is this fixed in Zope 2.4? ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
