Subject: bug#31715: cl-incf and cl-decf error out when passed a nil-valued variable as 'offset'
Date: Mon, 4 Jun 2018 16:06:55 -0400 [thread overview]
Message-ID: <1dff07f6-8da4-4e4c-a700-0bc39d6f2aa6@live.com> (raw)

Hi all,
The following works:
(let ((x 1)) (cl-incf x nil))
… but following raises "setq: Wrong type argument: number-or-marker-p, nil":
(let ((x 1) (y nil)) (cl-incf x y))
… yet the docs say this, which suggests that both should work:
(cl-incf PLACE &optional X)
Increment PLACE by X (1 by default).
The issue comes from the expansion of cl-incf:
(defmacro cl-incf (place &optional x) …
(if (symbolp place)
(list 'setq place (if x (list '+ place x) (list '1+ place)))
(list 'cl-callf '+ place (or x 1))))
Shouldn't that `if x' check be quoted? Same for the second branch of the if (shouldn't the `(or x 1)' part be quoted, too?)
cl-decf has the same issue. Am I missing something?
Clément.
