Subject: checking for nil argument in interactive
Date: Sun, 09 Nov 2008 14:57:22 -0600 [thread overview]
Message-ID: <87ej1kr51p.fsf@patagonia.sebmags.homelinux.org> (raw)
Hi,
I don't understand why the following arg symbol doesn't get set to
"string":
(defun funny-function (arg)
(interactive "sarg: ")
(if (not arg) (setq arg "string"))
(message "arg: %s" arg))
To test:
M-x funny-function RET RET
I've also tried (eq "" arg) for the if boolean but get the same result.
Any advice would be appreciated.
Cheers,

Seb
