The Zope management interface often uses constructions like: def (..., REQUEST=None): if REQUEST is not None: # through the WEB else: called directly You may use similar code.

This might have been resolved in > CVS, I don't know, should I post it as a bug? Erik, I'm afraid that your patch does not solve all the problems you mentioned in an earlier mail. You are right that the implementation of query_hook in Zope 2.3.2 and 2.4.0b1 cannot handle words with wildcards in nested lists, but your patch will lead to endless recursion, if you enter the most simple query: just one word without wildcards. In this case, "if ( (self.multi_wc in w)..." evaluates to false, hence self.erik_hook is call for this word, where "if ( (self.multi_wc in w)..." is again false, and erik_hook is called again... The statement "q = parse(s)" in UnTextIndex.query (and PositionIndex.query) before the call to query_hook can return nested lists, so query_hook must be aware of this. This can be done with: def query_hook(self, q): """expand wildcards""" words = [] for w in q: if type(w) is type([]): words.append(self.query_hook(w)) else: if ( (self.multi_wc in w) or (self.single_wc in w) ): wids = self.get(w) for wid in wids: if words: words.append(Or) words.append(wid) else: words.append(w) # if words is empty, return something that will make textindex's # __getitem__ return an empty result list return words or [''] You also mentioned the strange results of queries like "eri* and enge". These are caused by another bug in query_hook: The results from the wildcard expansion are simply inserted into the result list. Example: "ab* and xyz" may be expended by query_hook into ['aba', 'or', 'abb', 'or', 'abc', 'and', 'xyz'] Since UnTextIndex.evaluate looks first for 'and' operators, this is eqivalent to ['aba', 'or', 'abb', 'or', ['abc', 'and', 'xyz']] (The funny (or confusing) side effect is that "ab* and xyz" may return different results compared with "xyz and ab*", because "aba and xyz" probably gives results different from those for "abc and xyz".) but we need a result like [['aba', 'or', 'abb', 'or', 'abc'], 'and', 'xyz'] This version of query_hook below fixes the problem: def query_hook(self, q): """expand wildcards""" words = [] for w in q: if type(w) is type(''): if ( (self.multi_wc in w) or (self.single_wc in w) ): wids = self.get(w) alternatives = [] for wid in wids: if alternatives: alternatives.append(Or) alternatives.append(wid) words.append(alternatives or ['']) else: words.append(w) else: words.append(self.query_hook(w)) # if words is empty, return something that will make textindex's # __getitem__ return an empty result list return words or [''] You also mentioned the parse result ['abc', '...', '...', '...', 'def'] which you could not reproduce. Playing with Catalogs, I accidentally produced the corresponding query: '"abc ... def"', i.e., the double quotation marks are

It tells that a Python class can be both a class and an instance and that this view has interesting applications. You focus on the class aspects of a ZClass (a pattern for creating instances providing them with basic common infrastructure), while I stress the instance aspects. The fact, that you can manage ZClasses in the same way as other Zope objects, calls for similar structuring possibilities: taking them out of the centralized control panel and putting them anywhere in the site. That was the starting point of our discussion...

Re: [Zope-dev] Re: making zwikiwebs.zexp import unnecessary
It occurs to me that you may be confused as to why there are only two Wiki Pages stuck into a CMFWiki by the CMFWiki product. Especially if you haven't worked with the CMF. CMFWiki just creates a skin directory view with the Wiki DTML in it (a feature of the CMF that isn't available in regular Zope)... the only two pages that are non-help that are placed into an actual CMFWiki instance and FrontPage and SandBox. For vanilla ZWiki, I think what you'll need to do is register a "WikiWeb" constructor in the ZWiki __init__.py (much like you register one now for "WikiPage") That constructor method could construct a Folder object, and iterate over all the dtml and Wiki files in a subdirectory of the ZWiki package, adding them to the folder. I think you can rip most of this code right out of CMFWiki, though you may need to extend it a bit for DTML files if there are any.
