Subject: 29.3; python-ts-mode navigation fails
Date: Wed, 10 Jul 2024 09:45:01 +0000

[Message part 1 (text/plain, inline)]

python-nav-forward-defun doesn't work properly in python-ts-mode, for
example with this file:
https://raw.githubusercontent.com/timlod/onset-fingerprinting/6c8f9bd3b82398c9af3519036e0d5a550ad3bae7/onset_fingerprinting/data.py

Specifically, at some point it will stop navigating, even though there
are still function definitions to traverse (other times I saw it skipped
some definitions before stopping altogether). I noticed that this
usually happens after some point in the buffer, but I haven't been able
to nail it down exactly. My hunch is that it could be related to
decorators (e.g. @classmethod) or type hints, or both.

It does work properly using just python-mode. This is tested using
`emacs -q`, so this bug persists just on a clean Emacs 29.3.

I checked previous reports and believe this is probably related to
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=60856, which isn't fixed yet.
