(mu4e-message-at-point)

[Eduardo Ochs]

Hi Erich!

I want to ressurect this mailing list... can we use it for the
discussion? It seems that you are trying to write a function with
`find-find-links-links-new' - see:

  (find-eev "eev-tlinks.el" "find-find-links-links-new")
  http://angg.twu.net/eev-current/eev-tlinks.el.html#find-find-links-links-new

and `ee-template0', and I never wrote proper docs for that...

Here's a fixed & updated copy of the e-mail that I sent you.

You are in the right direction, but I haven't been able to make mu4e
work here yet... I have had to deal with situations similar to that a
handful of times - in which I had to learn how to use data structures
that are poorly documented - so I can sort of tell you what my hacking
tools looked like after N incarnations. I'll try to adapt them to your
case; the code is below. Note that will needs dynamic binding - see:

;; Here are some messages in help-gnu-emacs about dynamic binding
;; being deprecated:

Here is the code. By using `M-x m4s' to save a mu4e message in the
variable m4m we can use non-mu4e buffers for writing code and tests.
Note that the code below doesn't use `ee-template0' or
`find-find-links-links-new' yet, that will be the next step...



(setq m4m nil)

(defun m4s ()
  "Save the result of (mu4e-message-at-point) in the variable m4m."
  (interactive)
  (setq m4m (mu4e-message-at-point)))

(defun m4-eval (msg code)
  "Eval CODE in an environment in which some extra variables are available."
  (let* ((xid      (mu4e-message-field msg :message-id))
         (xsubject (mu4e-message-field msg :subject))
         (xmail-nr (mu4e-message-field msg :docid))
         (xfrom    (mu4e-message-field msg :from))
         (fromname (car (car xfrom)))
         (fromadr  (cdr (car xfrom)))
         (xpath    (mu4e-message-field msg :path))
         (xmaildir (mu4e-message-field msg :maildir))
         (xto      (mu4e-message-field msg :to)))
    (eval code)))

;;           (list (list "xid:" 'xid) (list "xsubject:" 'xsubject))
;; (find-epp (list (list "xid:" 'xid) (list "xsubject:" 'xsubject)))

(defun m4-main-fields ()
  (list (list "xid:"      xid)
(list "xsubject:" xsubject)
(list "xmail-nr:" xmail-nr)
(list "xfrom:"    xfrom)
(list "fromname:" fromname)
(list "fromadr:"  fromadr)
(list "xpath:"    xpath)
(list "xmaildir:" xmaildir)
(list "xto:"      xto)))

;; Tests:
;; (find-epp m4m)
;; (find-epp (m4-eval m4m 'msg))
;; (find-epp (m4-eval m4m '(m4-main-fields)))
;; (find-epp (m4-eval m4m '(list xfrom fromname)))
