Subject: Using let-bound var inside pcase conditions
Date: Mon, 17 Apr 2017 18:07:42 +0000 [thread overview]
Message-ID: <CAFyQvY2mmXaaC8kh6r6o5xZrtXSum8_oZ1G6Sfuaqy1WfuO+Ww@mail.gmail.com> (raw)
Hi,
I am trying to set the conditions in a pcase to variables, but cannot get
it working (See below dummy code).
Can you help fix the second message form below?
;; -*- lexical-binding: t; -*-
(defun pcase-test (var)
(let ((one 1)
(two 2))
(message "(good) Value is %s." (pcase var
(`nil "nil")
(1 "one")
(2 "two")
(_ "none of the expected")))
(message "(bad) Value is %s." (pcase var
(`nil "nil")
(`,one "one")
(`,two "two")
(_ "none of the expected")))))
(pcase-test nil)
(pcase-test 1)
(pcase-test 2)
(pcase-test 3)
