Subject: elisp--curent-symbol question
Date: Mon, 14 Nov 2022 07:00:44 +0100 [thread overview]
Message-ID: <AM9PR09MB4977CD669C5F8AC732F8BCEF96059@AM9PR09MB4977.eurprd09.prod.outlook.com> (raw)
The function looks like this:
;; returns nil unless current word is an interned symbol.
(defun elisp--current-symbol ()
(let ((c (char-after (point))))
(and c
(memq (char-syntax c) '(?w ?_))
(intern-soft (current-word)))))
Is there reason why this function is written that way and not like:
(defun elisp--current-symbol ()
"Returns nil unless current word is an interned symbol."
(intern-soft (current-word)))
Seems to me that checking for the first letter does not have any effect, but I
am maybe missing some special case? Doesn't 'current-word' obey rules for what
emacs lisp mode says is word anyway?
Also the comment seem to belong to doc-string rather than a comment outside the
function. Same follows for some other internal functions there, but that is a
minor, I am just wondering about syntax table and if I am missing something
there.
Thnks in advance for the answer.
