Subject: bug#5519: command-switch-alist
Date: Wed, 3 Feb 2010 23:07:26 +0000 (UTC)	[thread overview]
Message-ID: <alpine.LFD.2.00.1002032248370.29290@hafstormur.hafro.is> (raw)

The GNU Emacs Lisp Reference Manual (section 39.1.4) describes the 
variable `command-switch-alist', saying specifically that the CAR should 
be a string, _not_ including the initial hyphen.

My experiments indicate that the CAR string should indeed include the 
initialy hyphen. I can create a custom option using "-c",

   (setq command-switch-alist '(("-c" . (lambda (arg)(c-mode)))))
   $ emacs -c  # starts successfully in c-mode

but not using "c":

   (setq command-switch-alist '(("c" . (lambda (arg)(c-mode)))))
   $ emacs -c  # Emacs says: Unknown option `-c'

Therefore, it appears that there is a bug either in Emacs or the Lisp 
manual, since they disagree on whether the CAR string should include the 
initial hyphen or not.

Best regards,

Arni
