Syntax highlighting hangs when using a substring pattern with '

[kpietak]

I have come across a problem with highlighting sections of source code using a pattern/substring (as described in the https://nextra.site/docs/guide/syntax-highlighting#highlighting-substrings documentation).

I am presenting code in Rust that implements lifetimes annotations marked with ' , for example: fn longer<'a>(a : &'a [i32], b : &'a [i32]) -> &'a [i32].

I am trying to highlight the annotation itself ('a) using the code:

    ```rust /'a/
    fn longer_array<'a>(a : &'a [i32], b : &'a [i32]) -> &'a [i32] {
        ...
    }```

This syntax causes the page rendering to crash (even terminating the process causes the node to remain on). The question is do we not allow the use of this type of characters in the pattern or is this a bug?

The page rendering is running locally using pnpm dev on macOS. I would appreciate a reply.

seems like an upstream issue from rehype-pretty-code (package who add syntax highlighting for code-blocks) https://github.com/rehype-pretty/rehype-pretty-code

Please submit failling test there!

Thank you for a quick reply. I've just created a new issue in retype-pretty-code: https://github.com/rehype-pretty/rehype-pretty-code/issues/185
