MathRen (TeX math rendering)

Kylo

ParlorPink Yeah, I'm aware of that but I believe it has its own math functions?

askvortsov

Kylo hmm a while ago I added some support so that everything between dollar signs (whether sets of 1 or sets of 2) isn't escaped. But it doesn't add it's own math rendering. Do you know what the issues are?

Kylo

askvortsov oh this issue (the-turk/flarum-mathren29) might've confused me 🤦 I mixed up feature request & bug report on my mind and thought that two extensions are conflicting with each other. I haven't tested them yet tbh, and it was reported by a problematic user (smh) so maybe @ParlorPink can provide more details about this? Feel free to open a new issue on GitHub.

May be you can also ask to each members of you forum to contribute in the code or to give money to encourage the developer?

Have a nice day

Hi @Kylo
I currently use: /if/flajax
I would like to know if I can replace it with the-turk/flarum-mathren ?

Kylo

Natoons I think that extension looks up for $$ signs in posts, where MathRen replaces those signs with BBCodes as you typing/saving a post (for better Markdown support). If you want to switch to the MathRen, you should edit & save every post that contains mathematical expression, manually, one by one.

1.0.4

Requires Flarum v1.2.0+

Fix inline Litedown links have priority over regular BBCodes. (the-turk/flarum-mathren28)
Update KaTeX to v0.16.0 (see their changelog) - copy-tex now uses js instead of css which makes it more robust.
Update js dependencies and imports.
Uses new default extender instead of deprecated addSettings migration helper.
Uses exported flarum/mentions fragment PostQuoteButton instead of replicating it.

1.0.5

Fix code highlighting breaks when you interact with the page.

1.0.6

Add support for AsciiMath syntax. the-turk/flarum-mathren35
Add some CDN options which allows you to change them easily.

1.0.7

Add new delimiter options for AsciiMath syntax. - See it in action

Now I noticed that this extension actually requires PHP 8+ 🥸

I couldn't really find where the bug it is located in the source through dev. tools, since it's inside a minified forum JS file, so this is pretty much all that I know.

Seems like a minor syntax error to me, but perhaps this should be marked as incompatible for the time being?

Kylo

oh no what happened to my first boy 😭

guluting

Kylo I had the same problem 😭

Hi @Kylo,

I've checked the error code from Chrome Developer Tool and found the fourm.js generated improperly. When the katex.render() is called, the content generated would contain:

if (typeof katex !== 'undefined') katex.render(
  this.innerText,
  this,
  {{ "fleqn": !1,                                     // [HERE]
     "leqno": !1,
     "output": "htmlAndMathml",
     "throwOnError": !1,
     "errorColor": "#cc0000",
     "minRuleThickness": 0.05,
     "maxSize": 10,
     "maxExpand": 1000,
     "macros": {{}},                                  // [HERE]
     "colorIsTextColor": !1,
     "displayMode": !1
}})                                                   // [HERE]

Notice that it generates duplicate useless parenethesis both the outside object and the nested "macros":{{}}. This may relate to the TextFormatter you use in ConfigureTextFormatter.php.

Check this commit. This issue may be resolved after s9e/TextFormatter update. (Because that's the required packages of flarum/core).

Kylo

Hsins see the-turk/flarum-mathren38

can someone confirm if the latest TextFormatter master fixing this issue?

Kylo

okay now someone confirmed that this was an issue with the TextFormatter and updating it to the latest release fixed this issue: the-turk/flarum-mathren38

cilia

sadly this extension is not working again

Kylo

cilia can't help without any info

cilia

Kylo Sorry! forgot to post the errors

The one I got in the console is

sw:63    Uncaught (in promise) TypeError: Failed to fetch at sw:63:16

and also this warning

The FetchEvent for "<URL>" resulted in a network error response: the promise was rejected.

The out put of php flarum info is:
