I would prefer to avoid
in emacs init file and to postpone loading till invocation of
emacsclient with org-protocol URI.
The problem is a hack in org-protocol. URIs are actually treated as
(relative) file names and magic is achieved in an advice for
`server-visit-files' function. So the advice must be installed in advance.
My first idea was to avoid such magic and to create autoload function
org-protocol-from-argv with body similar to that advice. If it were
possible to get arguments from `command-line-args-left' then invocation
would look like
emacsclient --eval '(org-protocol-from-argv)'
Unfortunately it is against design of emacs server protocol. If --eval
option is given than everything other is considered as independent
expressions. At the lower level there is no way to transfer `argv` as a
list from client to server process.
It seems, it works if I add another advice to init.el that loads
org-protocol on demand:
(defadvice server-visit-files (before org-protocol-lazy-load activate)
(and (not (featurep 'org-protocol))
(mapcar (lambda (loc)
;; loc: (file-name . (line . column))
(not (string-match-p "\\(?:^\\|[/\\\\]\\)org-protocol:" (car
;; copy of org-protocol-detect-protocol-server advice,
;; move to a dedicated function
(let ((flist (if org-protocol-reverse-list-of-files
(reverse (ad-get-arg 0))
(client (ad-get-arg 1)))
(dolist (var flist)
;; `\' to `/' on windows. FIXME: could this be done any better?
(let ((fname (expand-file-name (car var))))
(setq fname (org-protocol-check-filename-for-protocol
fname (member var flist) client))
(if (eq fname t) ;; greedy? We need the t return value.
(ad-set-arg 0 nil)
(throw 'greedy t))
(if (stringp fname) ;; probably filename
(setcar var fname)
(ad-set-arg 0 (delq var (ad-get-arg 0))))))))))))
I hope, copy of original advice may be avoided by moving its body to a
separate function in org-protocol.
Do you have have better ideas how to avoid eager loading of org-protocol
from init file?
