Physikerwelt added a comment to T140217: Adjust texvcjs to prevent whitespace modifications in ce-tags.

I'm happy to review any pull requests... I have the complete list of all formulae used in the WMF wikis now. Thus, changing the grammar is less risky than it used to be.

Physikerwelt added a comment to T140217: Adjust texvcjs to prevent whitespace modifications in ce-tags.

oh no. This seems to be a regression. We updated the MathJax version last week and also enabled the new grammar based check for \ce tags T159735.
The input <ce>pIC_{50} = -\log_{10} (IC_{50}) </ce> should throw a warning, since it's not correct after the new grammar of @mhchem and @manfredschaefer since log is a math command, but not an error.
So from the grammar the input should be accepted at least it looks very similar to the test cases.
I'll look into it a bit deeper...

Physikerwelt added a comment to T183557: Mathoid v0.7.0 not accepting chem formula.

It sounds like the best way to go about this would be to fix these formulae manually? Maybe we should track down the pages using them and put a notice out for this?

Exactly. See my pull request that generates a warning for these problems. I think warnings are a very good mechanism to get rid of unhandy syntax.

With the first part of the fix the manual space correction is allowed (except for \; which would fix additional 2.2k cases.

I'm not sure I understand fully which fix you are referring to here. So texvc doesn't allow extra spaces right now but did in the previous version? Could we have it strip extra spaces? Is that even possible?

I replaced \; locally with a regular space for testing... However, doing that without side effects might end in a nightmare. Thus I think this is not a good approach.

But the old ce rule still wouldn't normalise the formula in such a way as to be compatible with the new texvc rules, so I'm not sure that would help us in the long run.

No, it would not help in the long run. But for the time being.

Physikerwelt added a comment to T183557: Mathoid v0.7.0 not accepting chem formula.

The problem is that the old verification added spaces in different places. Those spaces were sometimes not wanted, but sometimes required. Thus people started to adapt to this problem and fixed the spacing manually for instance by adding negative spaces or extra big spaces. With the first part of the fix the manual space correction is allowed (except for \; which would fix additional 2.2k cases. However, for the problem with missing spaces I have no good idea how to implement that. We could add a second phase that if a command fails in ce mode, we run the check with the old ce rule. However, this might lead to unexpected behavior and might confuse the final users.

Physikerwelt added a comment to T183559: Formula that passes the texvcinfo check fails to render.

I checked the render both cases with texvcjs. They all pass the tests even though they contain non valid latex characters. cf. https://github.com/physikerwelt/texvcjs/tree/invalid-input. I guess that the text field misses a rule that specifies which characters are supported by TeX or MathJax respectively.

Physikerwelt added a comment to T182316: Math end point responses should set the content-type's profile.

I had the feeling that the profiles extend the definitions of the format standards. i.e. for instance, the SVG documentation page should provide further details on the SVG format generated by the RESTbase endpoint that is not already specified in the SVG spec. As long as the math endpoint is the only endpoint that generates SVG this works fine. However, if e.g. graphoid would generate SVG as well this would be conflicting and a developer would like to know if the server response is a graphoid or a mathoid SVG...

Physikerwelt added a comment to T155201: Support shelling out to mathoid instead of requiring a full server/restbase setup.

https://gerrit.wikimedia.org/r/370603 is the first attempt for a CLI prototype on the mathoid side. Data is exchanged via pipes or files, so no network access required. Batch processing is supported, so that the same mechanism as in the restbase interface can be used and that requests can be bundled. This is required to save processing time when MathJax node starts. What remains to be done is to change the Math extension to shell out to mathoid rather than to texvc.

Physikerwelt added a comment to T160824: Instances in math project show high system CPU usage.

@Hcohl we need to take care of updating the drmf server. I suggest to rename drmf-beta to drmf and to start a new drmf-beta instance. What do you think?

Sorry for the delay in my response. Since Nov, 2016 a lot of changes happened... and I speculate that the problem was resolved in the meantime.

@mobrovac what's your feeling here: Update the apt repo or remove support for the packages?

@mobrovac the svg error is still present. Do you have any suggestions how to proceed here? Maybe we should make the comparison with the reference svg less strict?

Physikerwelt added a comment to T140217: Adjust texvcjs to prevent whitespace modifications in ce-tags.

@mhchem thank you. @manfredschaefer is developing a grammar for accepting the mhchem commands according to your template see https://github.com/manfredschaefer/texvcjs While this requires some effort I think it's the best solution to the problem.

Physikerwelt claimed T165751: Feature: Let Math accept certain Unicode input (eg. ∫ \frac{∂f}{∂τ}dτ ).

I like the idea. However, I think it would be better to replace the unicode chars by the respective commands for furhter processing. That way the formulae can still be rendered using pdflatex (with \usepackage{texvc}). Some symbols are already listed here https://github.com/physikerwelt/utf8tex/blob/master/unicode2classicTex.csv What do you think?

Physikerwelt added a comment to T166428: Extraneous horizontal space in an article.

the default css rules are

.mwe-math-mathml-a11y {
	/* We try to hide the MathML formula in a way that still makes it accessible to accessibility tools. */
	clip: rect( 1px, 1px, 1px, 1px );
	overflow: hidden;
	position: absolute;
	width: 1px;
	height: 1px;
	opacity: 0;
}

which is eventually changed to

/* Reset some CSS properties set by MediaWiki and hide the image fallback */
.mwe-math-mathml-a11y {
    clip: auto;
    overflow: visible;
    position: static;
    width: auto;
    height: auto;
    opacity: 1;
}

by the native mathml extension https://github.com/fred-wang/webextension-native-mathml/blob/master/content-scripts/mediawiki.css if mathml is enabled.

Physikerwelt closed T167569: MathRM parsing error as Resolved.

I guess what you are trying to do is to write chemical markup?
Have you considered using the chem tag instead <chem>HSO4-</chem> probably produces the expression you would like to discribe.
Can you explain why you want to use the mathrm command. Also note the difference between mathrm and operatorname https://tex.stackexchange.com/questions/48459/whats-the-difference-between-mathrm-and-operatorname
