The on-wiki version of this newsletter can be found here: https://www.wikifunctions.org/wiki/Wikifunctions:Status_updates/2025-03-07 -- Recent Changes in the software

The most visible change this week is that now, as we announced previously, wikitext links to Objects like [[Z12345]] will no longer have the label shown and instead just show their ZID, except on Special pages (T343483 https://phabricator.wikimedia.org/T343483). This old feature led to bugs and cache problems, and was not compatible with the new direction MediaWiki is going. This change makes wikitext links to Objects less magical, but preserves the usefulness on Special:RecentChanges https://www.wikifunctions.org/wiki/Special:RecentChanges and other important tools, similar to how Wikidata handles this.

In terms of smaller features, we're shipping a few this week, but very sweet ones: We have improved the collapsed view where there are calls using Types compounded of multiple inner values, like Z16683/Integers https://www.wikifunctions.org/view/en/Z16683, to use the display functions (T368324 https://phabricator.wikimedia.org/T368324). We have also improved the collapsed view of argument reference inside function calls, using the icon rather than the label for "argument reference" and so being more compact (T383883 https://phabricator.wikimedia.org/T383883). We now prompt Implementation writers that they can use Wikifunctions.Debug in their code to work out what's going wrong, and remind them to remove it before publishing (T355848 https://phabricator.wikimedia.org/T355848). We landed another keyboard accessibility improvement from User:Abbe98 https://www.wikifunctions.org/wiki/User:Abbe98, this time to make the ZID in the page title focusable, and allow its copy-to-clipboard feature to be triggered by pressing <Enter>. Thank you!

As part of our fixing bugs, we tweaked the styles of the short description input so that it doesn't overflow the column in narrower windows (T385993 https://phabricator.wikimedia.org/T385993). We fixed a bug that meant pressing the close button on the "in other languages" box didn't work; thanks to User:99of9 https://www.wikifunctions.org/wiki/User:99of9 for reporting that (T386315 https://phabricator.wikimedia.org/T386315). We replaced our custom code for the ModeSelector (move up/move down/delete control) with the newer Codex standard "MenuGroup" component, which will be more accessible and updated more consistently with the rest of the UX ( T384520 https://phabricator.wikimedia.org/T384520).

We also landed a major part of our code to integrate Wikifunction calls in wikitext with the visual and the 2017 wikitext editors, which we hope to show off soon!

In terms of engineering changes, we have expanded the testing for some of our critical code around setting up the page, as part of splitting this code up between 'client' code for Wikipedias and 'repo' code for Wikifunctions.org. This also allowed us to finally land a great patch from Aditya Kumar from late last year that use more robust tools to manipulate the URLs of pages we create links to, like history or edit pages (T360229 https://phabricator.wikimedia.org/T360229). We updated our front-end Pinia store code to replace anonymous getter functions with named functions, to help with profiling (T386188 https://phabricator.wikimedia.org/T386188). We fixed a bug in our logging that meant some monitoring didn't pass server-side validation (T385820 https://phabricator.wikimedia.org/T385820). We updated the selenium browser tests to adjust for the new Codex table usage we rolled out two weeks ago (T387540 https://phabricator.wikimedia.org/T387540), as part of wider work to run these tests in CI again.
