cl is a deprecated library, and elisp authors should use cl-lib
instead. In most cases, this is a matter of requiring "cl-lib" and
adding a "cl-" prefix to symbols that came from "cl".
This library provides an interactive command, cl-libify, which
replaces usages of "cl" symbols with their "cl-lib" equivalent,
optionally prompting for each
Note that some cl functions do not have exact replacements,
e.g. flet, so further code changes might still be necessary.
You can also use cl-libify-mark-cl-symbols-obsolete to mark old cl
names as obsolete, so that the byte compiler will help flag their use.
Ensure cl-libify.el is in a directory on your load-path, and
add the following to your ~/.emacs or ~/.emacs.d/init.el:
(require 'cl-libify)If you're an Emacs 24 user or you have a recent version of
package.el you can install cl-libify from the
MELPA repository. The version of
cl-libify there will always be up-to-date.
See the command cl-libify.
