Fix for :reg error in Evil08 Aug 2015
Small post with a fix for a (somewhat) common problem. If you use Emacs’ registers to save window or frame configurations, you probably found a small bug with the ‘:reg’ command in Evil-mode.
Fortunately, the solution is very simple, just apply this patch and it will work. Or you can just copy-paste and evaluate this code:
(defun evil-register-list () "Returns an alist of all registers" (sort (append (mapcar #'(lambda (reg) (cons reg (evil-get-register reg t))) '(?\" ?* ?+ ?% ?# ?/ ?: ?. ?- ?1 ?2 ?3 ?4 ?5 ?6 ?7 ?8 ?9)) (delq nil (mapcar (lambda (reg) (and (number-or-marker-p (car reg)) reg)) register-alist)) nil nil) #'(lambda (reg1 reg2) (< (car reg1) (car reg2)))))
