Place for Wikipedia in the framework
by Bináris 31 Mar '23

31 Mar '23

Tl;dr: is there a place for Wikipedia-related code? What do we do for code reusability? I proposed a Page method in https://phabricator.wikimedia.org/T328769. This would have shown if an article is a biography (it is about a person). My idea was opposed because the codebase of BasePage and APIPage is not Wikipedia-related, and some developers don't want to see any Wikipedia-specific code in it. OK, let's say, this is a valid argument. Let's call it *code purity*. On the other hand, Pywikibot is mostly developed by Wikipedians, mostly used in Wikipedia, and biographies form a primary scope of Wikipedia. I definitely think that biographies SHOULD be subclassed to have a lot of methods that are useful for a lot of Wikipedias and bot owners. If they write this code for themselves again and again, that's a waste. Now I definitely will use this feature. What can I do? First idea is to subclass Page in my code. That is the natural solution. Of course, when I publish my scripts, others won't be able to use them, and I won't be able to use others' scripts as they are, because I need this subclass. Let's call this point od view *code reusability* which is generally kept an important thing in the world of programming. Now, what we do (see the above task) is that we throw away code reusability for the sake of code purity. Is that OK? I am honestly curious, where the place of Wikipedia is in this framework. What I WILL do in the present situation: write a module called huwiki and don't bother other Wikipedias and place my code into this module. It will contain functions that take the page as parameter (not nice, not natural, I don't like it, but this is the only way if I cannot subclass) and nice pagegenerators, all for Hungarian Wikipedia alone, because I need them. Is that really what we want? Please help to find the place of Wikipedia-related code. -- Bináris

OFF: Idle 80

Wikipedia says me that Eric Idle (after whom IDLE is named) is 80 today. Well, on a Pythonic mailing list this may be interesting. :-) -- Bináris

Parallel gets?
by Roy Smith 28 Mar '23

28 Mar '23

I need to issue a bunch of Page.get() requests in parallel. My understanding is that pywikibot uses the requests library which is incompatible with async_io, so that's out. So what do people use? Threading <https://docs.python.org/3.9/library/threading.html>? Or, I see there's an async_io friendly requests port <https://github.com/rdbhost/yieldfromRequests>. Is there a way to make pywikibot use that?

Huwiki has new namespaces today, Pywikibot does not handle them
by Bináris 28 Mar '23

28 Mar '23

Today in wikipedia:hu namespaces 118, 119 were set. See T33308. https://phabricator.wikimedia.org/T333083 Now I have problems with the new namespaces. Message: KeyError: '118 is not a known namespace. Maybe you should clear the api cache.' Source: Pywikibot\pywikibot\site\_namespace.py >>> list(site.namespaces()) [-2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 90, 91, 92, 93, 100, 101, 710, 711, 828, 829, 2300, 2301, 2302, 2303] How to clear the API cache? Should Pywikibot automatically recognaize the new namespaces or shall I alter the code somewhere? -- Bináris

How to get enclosing section with mwparserfromhell?
by Roy Smith 24 Mar '23

24 Mar '23

To my surprise, wikicode.get_parent() does not get you the section a node is part of: > import mwparserfromhell as mwp > > text = """==foo== > {{Template:Foo}} > """ > wikicode = mwp.parse(text) > print(wikicode.get_tree()) > > print('++++++++++') > > node = wikicode.nodes[-2] > print(f"{node=}") > print(f"{wikicode.get_parent(node)=}") prints: > == > foo > == > \n > {{ > Template:Foo > }} > \n > ++++++++++ > node='{{Template:Foo}}' > wikicode.get_parent(node)=None Am I just doing this wrong?

How to avoid leaving extra blank lines when removing templates?
by Roy Smith 22 Mar '23

22 Mar '23

I've got some code which is essentially: > wikicode = mwp.parse(self.page.get()) > for node in wikicode.filter_templates(recursive=False, matches=title): > wikicode.remove(node) > self.page.text = str(wikicode) > self.page.save() which works, but it leaves an extra blank line behind where the template used to be. This is intended to be run on [[:en:Template talk:Did you know/Approved]], i.e. one template per line. What's the best way to get rid of the blank lines? I'm trying to avoid just running a regex replacement on the raw text because that's fragile, but maybe theres really no good alternative here?

Failing unit tests?
by Roy Smith 12 Mar '23

12 Mar '23

I'm gearing up to do some work (hopefully dive into fixing https://phabricator.wikimedia.org/T326650). I've gotten as far as closing the repo and running the existing unit tests. I get 4 failures: FAILED tests/make_dist_tests.py::TestMakeDist::test_handle_args - AssertionError: '/Users/roy/pywikibot/pywikibot-git/tests/make_dist_tests.py' != '/Users/roy/pywikibot/venv/bin/pytest' FAILED tests/make_dist_tests.py::TestMakeDist::test_handle_args_empty - AssertionError: '/Users/roy/pywikibot/pywikibot-git/tests/make_dist_tests.py' != '/Users/roy/pywikibot/venv/bin/pytest' FAILED tests/make_dist_tests.py::TestMakeDist::test_handle_args_nodist - AssertionError: '/Users/roy/pywikibot/pywikibot-git/tests/make_dist_tests.py' != '/Users/roy/pywikibot/venv/bin/pytest' FAILED tests/site_detect_tests.py::MediaWikiSiteTestCase::test_proofreadwiki - RuntimeError: Unsupported url: https://www.proofwiki.org/wiki/ <https://www.proofwiki.org/wiki/> Are these known issues? Or something wrong with my environment? I'm working on MacOS Monterey, with Python 3.9.
