Description

As stated in the release notes of Emacs 29 (https://git.savannah.gnu.org/cgit/emacs.git/tree/etc/NEWS?h=emacs-29), font-lock-reference-face has been removed since it was marked as obsolete quite some time ago already.
This yields an error similar to the following when starting Emacs 29.1 build 2 with the CoCoA 5 "extension" loaded:

Warning (initialization): An error occurred while loading ‘c:/Users/nicom/AppData/Roaming/.emacs’:

Symbol's value as variable is void: font-lock-reference-face

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace.

Luckily, font-lock-reference-face only has one occurrence in cocoa5.el and cocoa5.emacs, each.
A simple fix would be to just migrate to some other font face, i.e., replacing both occurrences with, for instance, font-lock-preprocessor-face.
It seems to be yet unused in regard to CoCoA 5. Otherwise, a collection of possible values is also available here: https://www.gnu.org/software/emacs/manual/html_node/elisp/Faces-for-Font-Lock.html

  • Target version set to CoCoA-5.4.2

Thanks Nico for the bug report.
I wonder why that face is even defined? When, if ever, is it used?
I have followed your advice about renaming it: I did initially try font-lock-number-face but that is not defined in my version of Emacs (27.1)
