Hi!

I'm using replace.py to create wikilinks. Usually I want to select only the first occurrence of the search string, and my command works fine for this.
I don't understand that, how do you select only the first one? For me, replace.py either changes each instance within a page, or nothing.

In the command I use, look at the end of the search and replace strings:

python replace.py -regex "(?si)\b((?:CCAT|Campus Center for Appropriate Technology))\b(.*$)" "[[\\1]]\\2" -exceptinsidetag:link -exceptinsidetag:hyperlink -exceptinsidetag:header -exceptinsidetag:nowiki -exceptinsidetag:ref -excepttext:"(?si)\[\[((?:CCAT|Campus Center for Appropriate Technology)[\|\]])" -namespace:0 -namespace:102 -namespace:4 -summary:"[[Appropedia:Wikilink bot]] adding double square brackets to: CCAT|Campus Center for Appropriate Technology." -log -xml:currentdump.xml

Notice that the -regex parameter is used, and the search text ends with (.*$), which matches the entire rest of the article. Thus that text is not searched again. It is replaced in the replace string by \\2, which I think means the second string from the search term.

I heard this tip from this mailing list over a year ago, and also from #regex on freenode - irc://irc.freenode.net/regex , which is an active and very helpful place to get regex help.

As far as I understand, at this opont replace.py gives the command to wikipedia.py:
new_text = wikipedia.replaceExcept(new_text, old, new, exceptions,
allowoverlap=self.allowoverlap)
So the solution should be in wikipedia.py.

Cool. Anyone have an idea what we can do with wikipedia.py?

Thanks
Chris
