[sudoskys]

Local rendering may introduce potential RCE, so we decided to build in some latex on http

[sudoskys]

Dense math tex may disrupt the continuity of reading.
And we can't convert them to png...
This will make copying inconvenient

[sudoskys]

Extending the parser for non-native grammars may cause undesired conversions to occur.

Publishing to an online service would also break the responsibilities of the dependent library.

So I decided to render the entire text paragraph in Latex and attach the original message.
Display it in the form of a caption. It ensures readability while being easy to understand.

I ran into problems with the implementation that the Python ecology couldn't solve:

The option that balances reproducibility and comprehensibility is to render additional images of paragraphs with latex and attach the original content. But the Python ecosystem makes this hard to do, and many latex tools require us to install the tex-live suite (which is huge) and render poorly. Maybe it's time to turn to the front-end tech stack
