Subject: eval-after-load confusion
Date: Wed, 30 Apr 2014 16:36:50 +0800 [thread overview]
Message-ID: <87k3a7i57h.fsf@ericabrahamsen.net> (raw)
I have the following in a library that is required at startup:
;; (eval-after-load 'message
;; (let ((ign-headers-list
;; (split-string message-ignored-mail-headers
;; "|"))
;; (our-val (concat gnorb-mail-header "\\")))
;; (unless (member our-val ign-headers-list)
;; (setq ign-headers-list
;; `(,@(butlast ign-headers-list 1) ,our-val
;; ,@(last ign-headers-list 1)))
;; (setq message-ignored-mail-headers
;; (mapconcat
;; 'identity ign-headers-list "|")))))
If I leave this block uncommented, I get a "void variable" error on
startup, referencing 'message-ignored-mail-headers.
I thought the whole point of `eval-after-load' was to avoid this: the
block should only be run *after* message.el is loaded, and
'message-ignored-mail-headers is defined. I've also tried with "message"
as a string, though that shouldn't matter.
Is it because it's referenced inside a `let' form? What am I not
understanding?!
emacs-version -> "24.3.1"
Thanks,
Eric
