Quoted rhs in <expr> mappings are highlighted as comments

[gpanders]

In the following mapping

nnoremap <expr> [a ":\<C-U>" . v:count1 . "prev\<CR>"

the right-hand side is incorrectly parsed as a comment.

Thanks for reporting !

I am looking into that right now.

[gpanders]

Thanks! I am looking into it too, but I am very much a tree-sitter noob so it seems likely you will figure it out before I do :)

To be honest, I think that the first thing would be to add basic support for map commands

[vigoux]

Then go incrementally from here

So, very basic support should have been adding in ee58a76 already.
Now we need to add everything that surrounds the mappings:

• Options (like <expr>)
• Keycodes (<CR> in the sides)
• And all the variants (will be boring AF)

This should have been fixed in the latest commit, closing.
