@Izno I do not know what the best way of implementing it in the extension is, but from an author point of view both are treated equally as part of a sentence and there is no difference between inline and block formula except for the size of the equation.

Debenben added a comment to T182127: Additional math symbols for oriented integrals.

If a symbol people need is missing or looks ugly, they will try to rewrite equations to make it work without the symbol or use some workarounds, e.g. in this case probably something like \int_C and then specify what C means. Those line integrals are common in complex analysis (residue theorem) and hence for example also in electrodynamics, I would estimate the number of articles where they could be used to more than 100 on enwiki.

I think people do not want to use \oiint or \oiiint because the integral symbol looks bad, they will prefer workarounds if they look better in their setup. It is probably not the biggest problem, but I would only consider the integrals in T182127 done, if they actually produce a rendering that is not ugly. I will close this task because I think it does not help.

The custom "Wikipedia syntax" suggested here would be a terrible idea. We are having enough trouble with non-standard LaTeX syntax already. At times, especially with mhchem or optional arguments (which use square brackets) it seems random, how an equation renders and if not what kind of error message you get. Even as an experienced mediawiki-user you can spend hours trying to find out where those strange error messages come from and how to fix them.

@Pkra About inlining SVG: Maybe you are right and in principle SVG could become a better solution than HTML. I don't like the idea of taking the current system and just removing the image tags because this is not enough to solve those problems. The most probable case is that we don't have enough manpower to actually do the things that "might be doable" and "require a bit of work" and the result is that we are stuck with an over-customized, substandard, unmaintained system forever.

@Theklan: We are currently discussing some changes to the math extension here: T195861, you are welcome to discuss this issue. Currently the plan is to

  1. get a correct rendering like in normal MathJax / LaTeX for all equations, especially mhchem
  2. render non-ASCII-characters like Cyrillic letters, äöü etc. properly in all browsers such that \text can be used with all languages that need special characters

As you can see this is a tremendous amount of work, progress is quite slow and everything relies on volunteers. I don't think changing the syntax for existing formulas with commas is feasible and maintaining the current system without additional localization features already overstretches our resources. I think it would be a better idea to just keep using the well-known {,} for decimal comma and make sure that help pages mention this LaTeX hack.

Debenben added a comment to T201233: Long math output unreadable on small screens due to scrolling off the side of screen.

I think one has to differentiate: Of course there are large formulas which cannot be broken and need some scrolling mechanism. Most formulas however have a structure like <math>A=B+C+D</math> which you can break almost everywhere if necessary. Wikipedia authors currently have a choice between

  • Adding permanent linebreaks or splitting the expression up in smaller chunks which means making it less readable by wasting space on large screens and/or introducing unnecessary artificial names for parts of the sum
  • Not adding any linebreaks, making the expression unreadable on small screens or introducing unnecessary scrolling or zooming.
  • Adding linebreaks like
First sentence
:<math>A</math><math>\;=B</math><math>\;+C</math>{{nowrap|<math>\;+D</math>.}}
Next sentence.

to force a correct linebreaking behaviour and an equal looking punctuation mark.

Yes, definitely. This would also solve part of T194768. With JS and Mathjax you can get this functionality easily, however in Wikipedia it seems to be a huge problem because most people get to see the math as images rather than text. We are trying to come up with a solution and would need some input from developers, see T195861.

Debenben added a comment to T197176: Install texlive-full package.

The goal of the project would be to verify that every mathematical formula uses proper LaTeX syntax. Because LaTeX is based on macros, this can be quite complicated and the only way to be 100% sure is to use LaTeX and render it. For example MathJax treats \overline and similar primitives like normal macros, thus it is sometimes more tolerant than other rendering engines.
