Does the Rich Text Editor (with Markdown) support math equations?

[erikm3103 (Erik)]

Hi everyone,

I’m using the Rich Text Editor (with Markdown) in WeWeb and I’m wondering if it currently supports rendering math equations using LaTeX or MathJax/Katex syntax or any other syntax?

I’ve tried a few standard formats, including:

• Inline math: $a^2 + b^2 = c^2$
• Block math:

$
E = mc^2
$

• Bracketed blocks:

\[
\frac{1}{2}mv^2
\]

• Markdown code blocks with math:

```math
\frac{1}{2}mv^2

But none of them seem to render as equations, just plain text. Does the WeWeb Rich Text Editor currently support math rendering?

Hi Erik ,

I don’t think our rich text editor has this functionality (at least without forking it and modifying it extensively)

Here’s how some other members have tried solving this:
(they embed Latex directly)

Math equations rendering through Latex

Hello, I want to showcase math equations on the website. I want it to be written in Latex. How can I render latex as maths? Do I store the latex code as it is in my Xano database, and when that is pulled, have some WeWeb functionality render the code as maths?

Latex embed not working

Hello, I put javascript in the header to allow for MathJax formulas. However, the formulas are not rendering. Anyone know why? Script: [Screen Shot 2023-07-28 at 5.05.59 pm]

Latex Not Updating with Dynamic Data

I am currently trying to load latex from a database to an element. I am able to render the latex using mathjax however once a question is loaded, it doen’t change even when new data is loaded. i tried updating the DOM using " wwLib.getFrontWindow().MathJax.typeset() " in a custom javascrip function but this only works the first time and doesn’t updated when other data is loaded. I have to constantly restart the page to view new rendered information. [image]

Let me know if these help.

Hi, you could use the Mathematics extension | Tiptap Editor Docs but as Augustin mentioned, it would require the fork of the current editor.

[erikm3103 (Erik)]

@Broberto @Agustin_Carozo Thanks to both Would be great to get this on the roadmap, so it can be suppoorted in the rich text field in the future.

Where can I submit feature requests again?

[Broberto (Rob)]

feedback.weweb.io - but there is very low chance that it’ll get implemented within a reasonable time.

[erikm3103 (Erik)]

Hi @Broberto @Agustin_Carozo

justed wanted to let you know that this is being implementend by Weweb as we speak and it should be released soon!

Not sure which approach they are going for, but yeah good news anyways!

[Agustin_Carozo (Agustin M. Carozo)]

Awesome!

[Agustin_Carozo (Agustin M. Carozo)]

Good news everyone!

The Rich text editor now supports writing and rendering math expressions!

Users of your apps can now write formulas, calculations, and other mathematical notation:

Hi Agustin! I am trying to render maths equations (LaTeX) but when I click either the inlineMath option or blockMath in the toolbar I’m getting this console error. It’s interesting because the ‘deprecated’ rich text editor block displays the latex fine. User error or bug?

Hey Jamie, this looks like a bug

Would you mind submitting a bug ticket here if you haven’t already?

[Joyce]

Hey @Jamier693

The team just pushed a bug fix to production. The math features should be back up and running

[dsturnerville (Derek)]

How can we disable this functionality? We use the rich text editor in a chat pane. When users try to mention more than one currency value it converts all text to a failed equation. “$6,500 or $3,700” results in this:

Hi Derek

This looks likes a bug. Would you mind creating a bug ticket here?

I’d do it myself to save you some time but that way you’ll be notified when the fix is live

[dsturnerville (Derek)]

I’ll create a ticket, however it is not a bug per se. According to LaTex docs, the two dollar signs triggers the functionality, however we need a way to disable it.

[Joyce]

Yeah, that makes sense. It’s technically expected behavior from LaTeX, but we could probably tweak our parsing so $$ only triggers when it’s actually part of a valid math expression.

Feel free to report is as feedback instead if it’s not a blocker for you. Either way, the team will take a look and find a solution but, if it’s a blocker, you should create a bug ticket and let us know so we can prioritize accordingly:
