I did the work, but unfortunately I am currently not yet familiar with all git/gerrit/phabricator processes, neither with core, so I publish my compat solution here, should anyone feel like transferring it to the production code or porting to core, just do it. Imagine any license you wish. :-) The whole thing is to double 2 small parts in pagegenerators.py and slightly modify them. Most complicated part was to write the comment. :-) 1. Go to "elif arg.startswith('-transcludes'):" line in pagegenerators.handleArg(), and insert after that block this part: elif arg.startswith('-toggletranscludes'): transclusionPageTitle = arg[len('-toggletranscludes:'):] if not transclusionPageTitle: transclusionPageTitle = pywikibot.input( u'Enter the desired template') transclusionPage = pywikibot.Page(site, "%s:%s" % (site.namespace(10), transclusionPageTitle)) gen = ReferringTogglePageGenerator(transclusionPage, onlyTemplateInclusion=True) Only the four red pieces differ from original. 2. Go to def ReferringPageGenerator( in the same file, and insert this modified version after the block: def ReferringTogglePageGenerator(referredPage, followRedirects=False, withTemplateInclusion=True, onlyTemplateInclusion=False): '''Yields all pages with their talk/non talk pair referring to a specific page. ''' for page in referredPage.getReferences(followRedirects, withTemplateInclusion, onlyTemplateInclusion): yield page.toggleTalkPage() Again, only the 3 red parts are different from the origianl block copied. A 3rd step is still missing, to list the new -toggletranscludes parameter in the docstring of the module. That's all.

How about a new argument to 'toggle' between content/talk namespaces in place? python script.py -namespace:1 -transcludes:MyTemplate -toggletalk -category:MyCat to cycle over every article in category "MyCat" whose talk page transcludes "MyTemplate".

2015-08-11 21:26 GMT+02:00 <info(a)gno.de>de>: This is a core stuff, isn't it? Sounds well for the first approach, but is slow. Anyhow, the task I work on will require such a two-step approach with saving and reprocessing, and this way it would be a 3-step process. The easy solution I sent a few hours ago (15:07 GMT) solves my problem and may be useful for others as I wrote.

2015-08-12 7:40 GMT+02:00 <info(a)gno.de>de>: Yes, but by that time I already wrote that I had changed the code in my working copy. Theoretically, your solution is really interesting, but as far as I see, for core users only, and it is anyway slower. I don't see how. Of course, I found this generator with this description: """ Wraps around another generator. Yields the same pages, but for non-talk pages, it also includes associated talk pages. This generator does not check if the talk page in fact exists. """ This has two problems: 1. Does not work in the direction I wanted, from talk to subject namespace, just from subject to talk. 2. Does not list only toggled pages but both original and toggled ones, which is not good for me and generally to speak not a clean solution. You are right that a general ToggleGenerator wrapper would be better solution than mine, but this is not it.
