In continuation of this, I started discussion on Commons Village Pump (http://commons.wikimedia.org/wiki/Commons:Village_pump#Should_categories_be_in_front_of_interwikis_or_other_way_around.3F ) about order of different parts of wikicode and Pywikipediabot attempts to standardize it. In particular I asked for opinions about preferred order of category and interwiki sections. If any of you are running Pywikipedia bots on Commons, I would like to invite you to this discussion.

Hello Jarek,

Is there any easy solution to this problem?

No, not really. At the moment, what happens is this: first, all interwiki links are removed from the page. Then, they are added to the bottom of the page.

This is - in general - a hard problem to work with. For instance, how should a page like

"blah text [[en:interwiki]] blah blah

[[fr:interwiki]]

[[nl:interwiki]]

[[category:cat]]"

be adapted? And how should a page like

"blah text

[[fr:interwiki]]

[[category:cat]]

[[nl:interwiki]]"

be adapted?

Changing the output to a different, but well-defined order is not that hard. Determining the correct order is. 

In this case, there are two options: thinking up some heuristic and implementing it, or doing some politics ('hey, if you don't *want* interwikis....'). 

If you want to work on the heuristic, the replaceLanguageLinks function in pywikibot/textlib.py is where you'd want to start.

Good luck (with either method ;-))!
