Hi, Each ns:0 page on English Wiktionary is divided into a bunch of sections headed by level-2 headers. The text of each level-2 header is the name of a language; e.g., ==English==. I use (something like) the following JavaScript when editing pages: txt = txt.replace ( /^==([a-zA-Z ]+)==\n+(?:(?:===|[^=]).*\n+)*/gm, function(section, langname) { return '' + section.replace ( /(\{\{homophones\|)([^=}]*\}\})/gm, '$1lang={'+'{subst:langrev|'+langname+'}}|$2' ); } ); This searches for {{homophones|...}} without a lang= parameter and adds the lang= parameter appropriate for the ==section== in which {{homophones|...}} appears. This works. I want to automate this, so wish to use pywikipediabot. So I've translated the above into Python as best I could, and come up with the following user-fixes.py : def homophix(match): return re.sub(r'(\{\{homophones\|)([^}=]*\}\})', r'\1lang={{subst:langrev|'+re.escape(match.group(1))+r'}}|\2', match.group(0) ) fixes['homophones'] = { 'regex': True, 'msg': {'_default':u'add lang to homophones'}, 'replacements': [ (ur'^==([a-zA-Z ]+)==\n+(?:(?:===|[^=]).*\n+)*', homophix) ] } ...which I then tried to call using python replace.py -fix:homophones -page:accapare (Note that [[wikt:en:accapare]] has {{homophones|...}} without = .) Python told me: No changes were necessary in [[accapare]] 0 pages were changed. So I guess it's either not matching or not replacing. What am I doing wrong? And what can I do instead? Thanks, Michael Hamm
