Subject: bug#23867: 25.1.50; Doc string containing `\N'
Date: Wed, 29 Jun 2016 18:44:51 +0900 (JST) [thread overview]
Message-ID: <alpine.DEB.2.20.1606291842210.1391@calancha-pc> (raw)
After commit
de7d5f36e0f3261a7300fa3a3d87ae3b758b8a73
a doc string cannot contain `\N'. It should be
written `\\N'.
For instance:
emacs -Q
;; create a file foo.el with contents:
(defun foo ()
"Test characters allowed in doc strings.
The following char is not allowed: `\N'
You need to double the slash."
(interactive)
(message "Test for doc strings"))
;; Load the file:
;; invalid-read-syntax Expected opening brace after \N
I saw 3rd party code with doc strings containing `\N'.
Should that 3rd party code update to `\\N'?
Or is OK to allow doc strings with `\N'?
