[Common Lisp] Package `cl` is deprecated: please replace it with `cl-lib`

[allentiak]

Perhaps you can use cl-libify for this?

[lebensterben]

Those warnings are coming from 3rd party packages. There is nothing we can do.

[Phundrak]

Indeed. The only instance of a (require 'cl) that I could find in Spacemacs’ own files is in frame-fns.el, and it is under a conditional for when the user uses Emacs 20 or below: (eval-when-compile (when (< emacs-major-version 21) (require 'cl))). However, Spacemacs supports Emacs 25.1 and above, I guess this could be removed? I don’t think there are many people using Emacs 20 and below anymore. Can they even use Spacemacs?

If you want to find out which 3rd party packages use the cl library, you could execute grep -rin "(require 'cl)" in your .emacs.d directory and open an issue for these packages specifically.

[emacs18]

I can find these just among 3 to 4 hundred package repos on my computer.

I'm not good at reading the lisp code but isn't the cl package required also here: https://github.com/syl20bnr/spacemacs/blob/383237ef295a07356deb79812952c9440c1d438b/layers/%2Bspacemacs/spacemacs-visual/local/zoom-frm/zoom-frm.el#L233 ?

[emacs18]

I think this file comes from emacswiki. This is not a file developed within spacemacs. Hence I think this should be treated as an external package.

[emacs18]

Drew Adams wrote many elisp code going back decades before package.el was developed. I think most of his work is still on emacswiki, and not packaged like most other elisp packages. That I think is why these files are handled specially. If zoom-frm was on a package archive, I think a copy of this file would not be within spacemacs repo.

[lebensterben]

Closing since these packages are out of our control.
