Commenting does not work

[marcinkoziej]

I'm on Emacs GNU Emacs 29.0.60 (and Doom Emacs config package)

I can't seem to get commenting work, that is, when I

1. start a comment // some comment
2. press return
3. I get a cursor at new line, but no // is added

I have all these gleam settings working:

  ;; Comment settings
  (setq-local comment-start "// ")
  (setq-local comment-end "")
  (setq-local comment-start-skip "//+ *")
  (setq-local comment-use-syntax t)
  (setq-local comment-auto-fill-only-comments t)

I did some investingation and Emacs (forward-comment 1) does not move the cursor at all.. Might be some lower level issue? (tree sitter vs syntax checking by newcomment.el ?).
I can run tree-sitter-debug and see comments detected correctly.
