To my knowledge nothing from cl-lib has ever been autoloaded (as those functions/macros are not commands it doesn't really make sense to autoload them). You need to require cl-lib, not cl-macs. Most of the time some package that you've loaded will have required cl-lib, that's why probably you didn't notice that it's not required by default.
Hello,
I have been trying to understand why some ERT unit tests I wrote fail in
Emacs 27 while they suceed in Emacs 26. After some head scratching I
found that the problem is caused by the fact that Emacs 27 does not seem
to know about the cl-case macro unless I (require 'cl-macs).
Indeed, if I try to byte-compile some trivial code like
(let ((x ?c))
(cl-case x
(?a 0)
(?b 1)))
in Emacs 27.1 or Emacs 27.2 I obtain these warnings:
In toplevel form:
test.el:1:1:Warning: ‘97’ is a malformed function
test.el:1:1:Warning: ‘98’ is a malformed function
In end of data:
test.el:7:1:Warning: the function ‘cl-case’ is not known to be defined.
Adding a (require cl-macs) to my code solves my problem, however, the
doc string of cl-case would suggest that this should not be necessary.
Am I missing something?
Thank you.
Best,
Dan
