KaTeX does not do what I need

[j3d1H]

I'm trying to write in KaTeX, specifically the symbol for a ray. However, in both my wiki and the actual plugin page, it doesn't work. I don't think it works on Khan Academy's GitHub page either. Has something changed? And, if I cannot use this, what else can I use to write the symbol for a ray, or things like that?

(I'm new to this plugin, and LaTeX in general. Maybe this never worked, or it changed a long time ago - I'm not quite sure.)

Any help is appreciated!

Hey j3d1H,

Can you post the actual latex you're trying to render?

Thanks,
Diego

Katex has a list of supported functions here https://khan.github.io/KaTeX/function-support.html

The tiddlywiki plugin is a little bit behind in terms of versions (I keep meaning to request an update but can't quite face git...)

Not sure what you mean by a ray.

Yesterday I updated the prerelease to the latest KaTeX, v0.90-alpha2:

https://github.com/Jermolene/TiddlyWiki5/issues/3086

https://github.com/Jermolene/TiddlyWiki5/commit/a88e28cb5afc2ddfefc95de0061d3f2b246c1c04

It will appear in 5.1.16. You can try it out here:

Best wishes

Jeremy.

Your a superstar!

Diego Mesa: I was trying to use \overrightarrow{AB}.

Ste Wilson: That is the site I was talking about.

Jeremy Ruston: I must have just barely missed it, because that's the site I looked at, and it didn't work there either. I have tried installing it on my wiki, and it worked.. but now it won't. When I drag the plugin's link to my wiki, even after fully uninstalling KaTeX, the links to the plugin itself won't work, and if I import those, the plugin does nothing. Did I break something?

\overrightarrow{AB} seems to work for me on the katex site.

I've tried it in tiddlywiki 5.1.1
5 (the latest release) and as you say it doesn't work.

I opened the latest version posted by Jeremy above and tried $$\overrightarrow{AB}$$ in a new tiddler and it works so it seems to be something added between the current and new versions.

If you drag the new katex plugin linked above into your tiddlywiki it should work... Back up first :)

I did what you said before, but now it works. I guess it was a matter of waiting - thank you!
