Pandoc syntax conversion issue

[wafflesatdawn]

I'm using Quarto with Hugo and a theme that incorporates a very odd Katex syntax for math equations: it users \( and \) as delimiters.

Rendering pages from Quarto causes the parentheses to be stripped and several lines of js/jquery to appear at the start of the .md file. To get my code to display correctly, I need to delete the js/jquery and correct the delimiters. I've tested on other pages and they don't have similar issues with the random js.

I think it's a Pandoc setting that's causing the behavior with the delimiters but have no idea about the js. If there could be a toggle or if Katex could be supported that'd be appreciated.

Could you share some small example for us to reproduce?
Note that I believe the issue you are having is as you said with Pandoc and not with Quarto directly.
Or, there might be some changes to be made in your katex setup (https://katex.org/).

Can you try to format your post better? If your file has triple ticks, surround it with quadruple ticks, and so on.

See https://quarto.org/bug-reports.html#formatting-make-githubs-markdown-work-for-us regarding how to include Quarto document in a post.

PS: why are you using the double dollars for multiline equations (display) and not the single dollar syntax for inline?

I've edited my reply using the 4x backticks as suggested--hope that helps!

Re: $ and $$ syntax, my Hugo theme won't process them the same way Quarto does. $$ syntax is allowed for separate lines but there is no single dollar version. Instead inline has to use \\( and ))\.

Unfortunately, your example is not reproducible.

Note that to have the correct Hugo syntax, you need for some reasons to double escape the equation.

{{< katex >}}

inline {{< katex >}}\\\\(ax^2+bx+c\\\\) inline

Or include it in a raw markdown block¹

Thanks for the reference link! The notation is now displaying correctly after escaping to raw markdown.
