Subject: Printing elisp char literals
Date: Mon, 26 May 2003 16:27:55 -0400 [thread overview]
Message-ID: <200305262027.h4QKRtlO001787@rum.cs.yale.edu> (raw)
Let's say I have an integer. How can I check whether it's a char ?
`char-valid-p' is only part of the answer, because I'd like to know
if the integer is a char-with-modifiers also. The best I could come
up with right now is:
(char-valid-p (logand char ?\x3fffff))
Is the mask available somewhere or do I simply have to hardcode it
like that ?
Furthermore, in order to print this integer in a form like ?\C-a,
what should I do ? The best I could come up with is:
(let ((s (single-key-description char)))
(while (string-match "\\`\\(\\\\[MCAHSs]-\\)*\\(\\)[MCAHSs]-." s)
(setq s (replace-match "\\" t t s 2)))
(concat "?" s))
