Hi Yuan:

The cuda mode seems to work now. I am still testing and fixing details,
but so far now it works.

However I have detected another issue that I thought was related with
the remap, but it is not because I got it also in normal c++-ts-mode:

When c-ts-mode-enable-doxygen is enabled and the cursor moves inside a
doxygen comment I get this error:

Debugger entered--Lisp error: (treesit-predicate-not-found ("Cannot find the definition of the predicate in `treesit-thing-settings'" list))
  (treesit-parent-until #<treesit-node description in 7380-7452> list)
  (treesit-show-paren-data--categorize 7376)
  (treesit-show-paren-data)
  (show-paren-function)
  (apply show-paren-function nil)
  (timer-event-handler [t 0 0 125000 t show-paren-function nil idle 0 nil])

If you prefer I can open a new issue for this, but maybe it is not needed.

Best,
Ergus
