Custom Message-ID

Custom Message-ID

[Byung-Hee HWANG (황병희)]

Firstly, i would like to give "Big Thanks" to Jorge and Emanuel about
two weeks ago, thanks to them, i got my style's citiation in Gnus. That
is so happy.

Today i have more question.

Really i am literary man rather than computing man. One by one i am
making my style's Gnus.

In Message-ID of Gnus, i want to put a prefix "yw" into front of
Message-ID. The "yw" is special to me. That is all. But i failed to
search a way. As you know, i am not programmer nor elisp expert.

I searched google, and i looked some .el files in gnus directory. Maybe
message.el seems to have hints. But i don't know what key is.

Anyway i want a Message-ID as below: (example)

       <yw.87jdfsfms7838.fsf@myhost.fqdn>

Thanks for Advance!!!

You're looking for `message-unique-id', and unfortunately it doesn't
seem like you have any access to the string it produces. Sorry! You'd
probably have to override that function to get what you want.

Well, obviously you are welcome, but thank us
even more by making sure always to process the
information (even when it doesn't help or you
don't agree), that way, helping you solve
problem A will given time and effort prepare
you to solve problem O without help, and with
even more time and efforts you can help someone
else - perhaps even us - solve yet
another problem!

You can be both! Start today!

I don't think this is a problem that a lot of
people have solved because it is in the
mageo-mythical domain :)

There are 93 occurrences of "Message-ID" in the
Gnus manual, and 8 in the "message manual" (or
info file).

It is a good start and probably a quick check
(open the file in Emacs, then do normal search,
or use the Emacs info interface if you are
comfortable with that).

    93   emacs     /usr/share/info/emacs-24/gnus.info
     8   emacs     /usr/share/info/emacs-24/message.info

The Message-ID header "contains a unique
identifier for this electronic mail message.
This is constructed by using the originator's
domain name for the domain component along with
a locally generated string". [1, p. 96]

Now, if something is unique, and you append
something to it, is there a hazard the result
won't be unique? Well, it depends, but I think
it should be safe.

Here is the code you need, from

    /usr/share/emacs/24.4/lisp/gnus/message.el.gz

starting at line 5544, with only one change (at
line 15, or "5559").

;; If you ever change this function, make sure the new version
;; cannot generate IDs that the old version could.
;; You might for example insert a "." somewhere (not next to another dot
;; or string boundary), or modify the "fsf" string.
(defun message-unique-id ()
  ;; Don't use microseconds from (current-time), they may be unsupported.
  ;; Instead we use this randomly inited counter.
  (setq message-unique-id-char
	(% (1+ (or message-unique-id-char
		   (logand (random most-positive-fixnum) (1- (lsh 1 20)))))
	   ;; (current-time) returns 16-bit ints,
	   ;; and 2^16*25 just fits into 4 digits i base 36.
	   (* 25 25)))
  (let ((tm (current-time)))
    (concat
     "yw."
     (if (or (eq system-type 'ms-dos)
	     ;; message-number-base36 doesn't handle bigints.
	     (floatp (user-uid)))
	 (let ((user (downcase (user-login-name))))
	   (while (string-match "[^a-z0-9_]" user)
	     (aset user (match-beginning 0) ?_))
	   user)
       (message-number-base36 (user-uid) -1))
     (message-number-base36 (+ (car tm)

I think you can use advice instead, since you just want to prepend a string:

(defun yw-message-unique-id (original)
  (concat "yw." original))

(advice-add #'message-unique-id :filter-return #'yw-message-unique-id)
(message-unique-id) ;; "yw.random ID"

;; then you can remove it
(advice-remove #'message-unique-id #'yw-message-unique-id)

That can go in your emacs.el and leave message.el clean unpatched :)

Now let's think about this in all
clear-headedness possible to upbring.

In theory, there are no Elisp experts.
There are only Lisp (or LISP) experts!

In practice, I suppose the most experienced
Emacs developers, e.g. [names removed by the
anti-namedropping filter], are likewise Elisp
and Lisp experts.

Certainly more the expert style but do it too
much and you won't know your name :)

This works for me with no complains from the
byte-compiler:

    (require 'message)
    (add-function :filter-return
                  (symbol-function #'message-unique-id)

First of all, your codes is so beautiful!!!

Then, it is start my story...

My Emacs version is old, so i did download from git server of GNU,
branch emacs-25. The file name is nadvice.el, i found the variable
`add-funcetion' in nadvice.el. Actually for some reason, i cannot
upgrade to emacs 25. 

### begins here: emacs error messages by M-x byte-compile

Sorry. As you see above, i did myself best to write the variable
`add-function'. In current, below is my environments:

Really Thank You Andreas!

Very detailed. To non-expert like me, it is same so so both lisp and
elisp ^^;;
