Emacs 28 TODO

[mmontone]

When ready to switch to Emacs 28 do:

• Add mode to interactive expressions. See: https://lars.ingebrigtsen.no/2021/02/16/command-discovery-in-emacs/
• Replace define-key (deprecated) with keymap-set.
• Look at pp- variables. Not available in all versions.

Replace define-key (deprecated) with keymap-set.

define-key is certainly not deprecated, in fact that is what keymap-set uses internally! And note that the keymap module was added in Emacs 29

[mmontone]

Ah! Thanks for the clarification.

[mmontone]

But ...

It says it is "legacy" in docs ,whatever that means.

[phikal]

Good point, missed that. I've sent a message to emacs-devel to clarify the issue: https://lists.gnu.org/archive/html/emacs-devel/2022-07/msg01078.html.

Lars responded:

[...] `define-key' is not (and won't be) obsoleted, so it's up to them to follow the recommendation (or not).
