commands VS KaTeX

It's CodeMirror! All I had to do was write a Janet grammar for it -- very easy to do. CodeMirror is pretty amazing -- I was able to implement the "edit values with your mouse" by just asking CodeMirror for the syntax node under the cursor, checking if it parsed as a number, and if so replacing it with a different string.

I went with CodeMirror after reading this post that compares a few different editor components: https://blog.replit.com/codemirror and I've been super happy with it.

The wrighter editor is built on top of codemirror and bytemd. codemirror is the go-to choice when it comes to flexible/hackable text editing and bytemd provides a nice wrapper for codemirror using react with some extra functionalities. I wanted to create a fork of bytemd that includes all the WYSIWYM features that I built for wrighter, but it was out of scope and takes too much time.

I will just use technology I am familiar with. Tauri + CodeMirror + CM's Common Lisp mode should hopefully get me a long way.

And the second video is an example of me converting some messy vanilla JavaScript code for initializing and accessing multiple CodeMirror code editors to clean, encapsulated, well-organized web component code. (Still vanilla!)

You can check out the CodeMirror library - https://codemirror.net/ It seems to be great match for this case.

Try it out in your editor and it should work a dream. For all of the possible commands, you can add check out the command repo's README.

I want to resolve this KaTeX issue, so in order to test my ideas, is there some LaTeX test file with just a lot of equations, preferably inline (since this issue is related to inline math) but without fancy libraries or stuff not included in KaTeX?

I started using KaTeX sometime after 2015 because it promised to be fast (the fastest! [1]). I had to change the representation of a bunch of expressions because KaTeX didn't support some environments, whilst MathJax did. It was a trade-off I was willing to accept at the time.

Many years later, I started writing a personal static-site generator. I wanted comparatively lightweight pages, so rendering server-side was an option. I re-evaluated MathJax vs KaTeX again and this time I leaned towards MathJax, as speed was no longer an issue for me. It looks like KaTeX has broader support now [2].

Another alternative: Create a WebView by using UIViewRepresentable and Webkit together with MathJax or Katex where Katex is the better option. Here is a link to katex: https://katex.org/

This isn't a LaTeX question. It's a web dev question. Probably best directed at folks who make (or use) KaTeX.

If you want to make it from scratch, go with https://www.slatejs.org/examples/richtext, then use something like https://katex.org/ for rendering the LaTeX, and maybe Mathjs.org for plotting.

The speed of KaTeX is great, but the lack of support for diagrams (a la tikz-cd) is what makes KaTeX unsuitable for general adoption by mathematicians (e.g., mathoverflow.net and all online mathematical wiki I know use MathJax). KaTeX has some rudimentary support for diagrams though the {CD} environment, but something more fully fledged akin to tizk-cd or xymatrix is needed. There's been some discussion on their github (https://github.com/KaTeX/KaTeX/issues/219), but I wouldn't hold my breath.

Haven't personally used it, but have heard of KaTeX
