3 years ago I assume this is something to do with [[Wikilink]] parsing, but I don't know enough Rust to investigate sweat_smile I think a possible solution would be to ignore any parsing or modification inside math blocks and instead treat them verbatim.
It's unfortunately a little bit more complex than that.
I use pulldown-cmark to parse the Markdown document, which for this input:
# Heading 1
## Heading 2
### Heading 3
> Single line quote.
---
> Multi-paragraph quote, line 1.
>
> Multi-paragraph quote, line 2.
> Multi-paragraph quote, line 3.Generates these events:
Start(Heading(1))
Text(Borrowed("Heading 1"))
End(Heading(1))
Start(Heading(2))
Text(Borrowed("Heading 2"))
End(Heading(2))
Start(Heading(3))
Text(Borrowed("Heading 3"))
End(Heading(3))
Start(BlockQuote)
Start(Paragraph)
Text(Borrowed("Single line quote."))
End(Paragraph)
End(BlockQuote)
Rule
Start(BlockQuote)
Start(Paragraph)
Text(Borrowed("Multi-paragraph quote, line 1."))
End(Paragraph)
Start(Paragraph)
Text(Borrowed("Multi-paragraph quote, line 2."))
SoftBreak
Text(Borrowed("Multi-paragraph quote, line 3."))
End(Paragraph)
End(BlockQuote)Then I do some logic to replace [[WikiLinks]] correctly and feed the above stream of events to pulldown-cmark-to-cmark to convert this into Markdown text again.
There are some complexities here:
- pulldown-cmark doesn't understand LaTeX math blocks, so we're treating this as regular pieces of text.
- pulldown-cmark-to-cmark escapes any lone
[character (so it becomes\[) as part of its text encoding, because if it doesn't escape this, it denotes the start of a link.
What pulldown-cmark-to-cmark is doing is technically correct, though I think if it simply didn't do this, you'd get the correct behavior you're expecting.
We might be able to convince the pulldown-cmark-to-cmark authors to make this behavior configurable. I don't feel like doing this right now, but I'll file an issue on their repository somewhere in the next couple of weeks and explain this use-case to see how they feel about that.

Hi there, this program has been immensely useful for getting my Obsidian docs into
LaTeX, so thank you 🙏.I've noticed that certain blocks of mathematics (in
LaTeX) are handled incorrectly, breaking the math environments. For example, if you include a left-bracket in aLaTeXenvironment (such as$[0, 2\pi)$), afterobsidian-exportis run it will be converted to$\[0, 2\pi)$(which is invalid).I assume this is something to do with
[[Wikilink]]parsing, but I don't know enough Rust to investigate 😅 I think a possible solution would be to ignore any parsing or modification inside math blocks and instead treat them verbatim.
