Nice command, but fails for me right now with
Wrong type argument: stringp, (flycheck . "0.16")
(emacs-repository-get-version)
"f97a7d9a833044a828e0ce96ae3df600d613b359"
in lisp/cus-edit.el :
(let (found)
(mapatoms
(lambda (symbol)
(let* ((package-version (get symbol 'custom-package-version))
(version
(or (and package-version
(customize-package-emacs-version symbol
package-version))
(get symbol 'custom-version))))
(if version
(when (customize-version-lessp since-version version)
(if (or (get symbol 'custom-group)
(get symbol 'group-documentation))
(push (list symbol 'custom-group) found))
(if (custom-variable-p symbol)
(push (list symbol 'custom-variable) found))
(if (custom-facep symbol)
(push (list symbol 'custom-face) found)))))))
(get symbol 'custom-version) is not a fail safe value to pass to #'customize-
version-lessp since it returns a cons where you need a string.
The #'customize-version-lessp function tries to compare the former which is the
package version (say for me, it fails with '(flycheck . "0.16") ) whith the
latter which is "24.1" (the emacs since-version). This has to be fixed albeit I
have no idea about the best way to do it.
