Physikerwelt added a comment to T196590: Unable to install Math extension with MediaWiki-Vagrant on labs.

@brion do you have a suggestion, where and how to document how this decision was made?

@Debenben can we put the source code of the bot to a public repository. Otherwise, it might hard to decide if the bot flag should be granted. Or did I just miss the link to the bot code?

Physikerwelt added a comment to T173949: Lua module Module:Internet_Archive is causing parser cache pollution - ext.math.styles is sometimes loaded.

@Jdlrobson from my understanding what happens during hook registration code is that this code is only called if the parser sees a math,ce, or chem tag in the template expanded wikitext. I could imagine that during template expansion math tags might appear under certain circumstances. But this is really a wild guess.

Another potential source of caching problems is the setting dependent cache key https://github.com/wikimedia/mediawiki-extensions-Math/blob/df1689c7177d5b7ef946ae2ff525594bd377da3f/Math.hooks.php#L133-L136 depending on the user setting for math rendering different versions of the page are served. I am happy about any suggestions, how the code could be improved.

Cool. As long as the not does not perform braking changes such as macro expansion for $ and % and \or I don't see any problems. However, as soon as we do breaking changes we also have to change the tag name or add an attribute. Otherwise old revisions would not render correctly. Once we agreed to a new syntax we could maybe migrate to a new tag name such as formula.

@Pkra I started with the same impression. But over the last years, the processes inside WMF are much clearer to me. While one might at first glance get the (wrong) impressions that "they" rejected things because "the staff" has more rights, time and power I can now understand the rationality behind these decisions. If there is something we cannot implement as volunteers, we need to request for resources (about one year in advance). To send a request that is likely to be approved we need a proposal as explained in the description of the ticket.

@Pkra I am quite certain that there is nobody at WMF that has a strategy for the future of math. Thus we need to take care of it by ourselves in the wiki way. Now I am making a broad claim: Neither WMF nor WMDE will stop us from improving the math support if it is reasonable.

For the regression test, we could reuse mathpipe (description). However, it would be good to update to the latest selenium version to get a realistic rendering, how it would look in the browser. We are currently using MathJaX's SVG output to generate the images.

If you look at the wikitext, you see that this was not written as a math tag, but using a template {{Intorient|symbol=varoint}} , which links to an SVG file on commons. Thus the addon of @fredw is not aware that it's a math symbol.

Physikerwelt added a comment to T188879: Remove texvc.

@Debenben Now, since we have stopped using texvc in production, we are technically in a position that we can change anything we can image. However, the things you mention require a lot of work thus we should make sure, to plan wisely before we start with the implementation and to make sure the implementation suites the community needs. I would, therefore, suggest that we form a committee that discusses the changes we want to make to the <math/> tag before we start with the implementation.

@Lucas_Werkmeister_WMDE with original TeX string you mean the userInputTex. It has been shown, that this representation is not suitable for Math Information Retrieval Tasks. Also, note that you need to install texvc in order to render the userInputTex. Reading the request a query page, I wonder what the underlying information need of the user was. Does it fall into the "what is the name of the formula ..." category?

@mobrovac simple but not trivial. We could introduce another class (e.g., MathPNG) based on the MathML class that overwrites the output method only. This class would always deliver png rather than mathml + svg fallback.

Physikerwelt added a comment to T192351: Math extension not usable without RESTbase server.

@ePirat I have tested that in CLI mode recently. The advantage of this is that the rendering results are cached in the database. Thus if you customize the mathoid server, you might want to purge the caches, by truncating the mathoid table in the database. Of course adding action=purge works as well on a page by page basis.

Physikerwelt closed T184355: Update MathJax/mhchem as Declined.

@mhchem we discussed incompatibilities, off list. Thus just adding the option does not work. Thus I'm closing this task until there is a plan how to make the new version available.

I don't see it either. Maybe it was automatically deleted when I deleted the instance yesterday.

@Kelaun I have restarted api.formulasearchengine.com . It was crashed, but your input should render now. Can you update to the latest version of core and the math extension as described here T188745?
