Lychee trys to parse math equation leading to erroneous error message.

[etpalmer63]

For example:

$$
[\psi](\mathbf{L}) 
$$

Is interpreted as a link and checked, giving an erroneous error message.

Is there anyway to workaround this? -- Thank you!

I'm assuming that's inside a Markdown file?

Well, you can exclude it with --exclude mathbf until we fixed the bug.

Ah thank you @mre ! I didn't realize the exclude would be that easy so I hadn't even looked yet. Thanks!

Also, yes. This is inside a Markdown file.

The solution to this bug is to support the maths syntax. We wouldn't really want to work out a spec and add custom parsers atop pulldown-cmark, so we are blocked on this being supported upstream.

It looks like there is some interest: https://github.com/raphlinus/pulldown-cmark/pull/622 https://github.com/rust-lang/mdBook/issues/2222

As this bug has a workaround, I think it would be ok to close this issue with the stance that we will support maths syntax when pulldown-cmark does. Of course, discussion can still take place on the closed issue and it can be re-opened by anyone who wishes.

@mre I will leave closing this to you if you agree.

Good call. Seems like upstream process on this feature is slow, so might not make much sense to hold our breath before it lands. Closing. In case this gets merged in the future, I'd be thankful if someone could reopen the issue.

@mre this could be re-opened

Thanks for the notification.

Thank you both for getting this done! 🙏
