Replace deprecated cl by cl-lib
Closed this issue · 3 comments
Since Emacs 27, the package cl is deprecated (and issues a warning: Package cl is deprecated). The replacement for cl is cl-lib.
I would like to provide a PR which ports all el-get code to use cl-lib, instead of cl. For this, it would be best to drop support for Emacs versions less than 24.3, because since Emacs 24.3, cl-lib is builtin and doesn't need an extra package from ELPA.
What do you think, can I go ahead?
I think its reasonable to drop support for <24.3. its almost 8 years passed since 24.2 is released. I still come across earlier versions of emacs on some linux servers that I use, but again with so many incompatibilities, now a days I tend to install latest version of emacs in home directory on those servers.
So yes, I support such change.
As Emacs now issues a deprecation warning, it is time ;-)
I tried just simple-minded replace all (require 'cl) with (require 'cl-lib) which seems to be the prefered replacement, but the tests did not run with that change...
EDIT: I missed the PR, thanks @stephan-cr
