Hi all

Treesit is broken for csharp-mode in the latest version in master and emacs-29 and therefore does not provide syntax highlighting. 

The latest grammar repository (https://github.com/tree-sitter/tree-sitter-c-sharp) has removed the keyword void_keyword.

Please see attached the patch to resolve the issue.

Thanks
Jean M

Thanks, but your patch will not work with the older version of the
grammar library, right?  Is it possible to make a patch that will work
with both?  Wed cannot rely on users having the latest grammar
versions, so a backward-compatible change is much more preferable.

We've had some similar patches lately that you can use for inspiration.

Thanks,

Ping!  Can we please have a patch that is backward-compatible?

Thank you!  Should we perhaps swap the order, and query first about
the newer type, so as to make the code a bit faster when used with the
latest grammar?

Thanks, installed on the emacs-29 branch, and closing the bug.

Please in the future accompany your changes with a ChangeLog-style
description of files and functions where you make changes (I did it
this time for you).
