Use KaTeX instead of MathJax

Is it any way to configure ReText to use KaTeX instead of MathJax? I am working in an environment where KaTeX is the only option and it would be great if I could use my favorite markdown editor.

Hi! Unfortunately it is not possible yet.

Can you share a detail why KaTeX is the only option? Will it be an option to download and unpack MathJax locally, and use it?

Thank you for your quick answer. The reason for asking about KaTeX is that the editor should support GitLab-style markdown, which AFAIK uses KaTeX. Now that you answered 'no', I'm thinking I might get by with just configuring ReText/MathJax to use GitLab-style $`...`$ and ```math...```. Is it possible to to that? And if it is possible, how can it be done?

Hi!

I added GitLab support to the math extension ReText uses. To upgrade it before I officially release it, use this command:

python3 -m pip install --upgrade --user https://github.com/mitya57/python-markdown-math/archive/master.zip

Then, you can use GitLab syntax in your markdown files:

<!-- Required extensions: mdx_math(use_gitlab_delimiters=1) -->

Inline: $` e^{i \pi} = -1 `$.

Standalone:
```math
e^{i \varphi} = \cos \varphi + i \sin \varphi
```

Please test and give your feedback, then I will release the update to PyPI.

It works! Thank you. It even works globally with mdx_math(use_gitlab_delimiters=1) Do you have a way to define shortcuts? (I mean without editing /usr/share/retext/ReText/editor.py if possible...)

It works! Thank you.

Thanks for confirming this, I have released python-markdown-math 0.7 to PyPI yesterday which has this functionality.

Do you have a way to define shortcuts?

No, unfortunately. Is there any specific shortcut you want to have?
