;;; Commentary:
|
||
|
||
;; This file ensures that, when the point is in a To:, CC:, BCC:, or From:
|
||
;; field, word-abbrevs are defined for each of your mail aliases. These
|
||
;; aliases will be defined from your .mailrc file (or the file specified by
|
||
;; `mail-personal-alias-file') if it exists. Your mail aliases will
|
||
;; expand any time you type a word-delimiter at the end of an abbreviation.
|
||
;;
|
||
;; What you see is what you get: if mailabbrev is in use when you type
|
||
;; a name, and the name does not expand, you know it is not an abbreviation.
|
||
;; However, if you yank abbreviations into the headers
|
||
;; in a way that bypasses the check for abbreviations,
|
||
;; they are expanded (but not visibly) when you send the message.
|
||
;;
|
||
;; Your mail alias abbrevs will be in effect only when the point is in an
|
||
;; appropriate header field. When in the body of the message, or other
|
||
;; header fields, the mail aliases will not expand. Rather, the normal
|
||
;; mode-specific abbrev table will be used if
|
||
;; defined. So if you use mail-mode specific abbrevs, this code will not
|
||
;; adversely affect you. You can control which header fields the abbrevs
|
||
;; are used in by changing the variable mail-abbrev-mode-regexp.
|
||
;;
|
||
;; If auto-fill mode is on, abbrevs will wrap at commas instead of at word
|
||
;; boundaries; also, header continuation-lines will be properly indented.
|
||
;;
|
||
;; You can also insert a mail alias with mail-abbrev-insert-alias
|
||
;; (bound to C-c C-a), which prompts you for an alias (with completion)
|
||
;; and inserts its expansion at point.
|
||
;;
|
||
;; This file fixes a bug in the old system which prohibited your .mailrc
|
||
;; file from having lines like
|
||
;;
|
||
;; alias someone "John Doe <doe@quux.com>"
|
||
;;
|
||
;; That is, if you want an address to have embedded spaces, simply surround it
|
||
;; with double-quotes. This is necessary because the format of the .mailrc
|
||
;; file bogusly uses spaces as address delimiters. The following line defines
|
||
;; an alias which expands to three addresses:
|
||
;;
|
||
;; alias foobar addr-1 addr-2 "address three <addr-3>"
|
||
;;
|
||
;; (This is bogus because mail-delivery programs want commas, not spaces,
|
||
;; but that's what the file format is, so we have to live with it.)
|
||
;;
|
||
;; If you like, you can call the function define-mail-abbrev to define your
|
||
;; mail aliases instead of using a .mailrc file. When you call it in this
|
||
;; way, addresses are separated by commas.
|
||
;;
|
||
;; CAVEAT: This works on most Sun systems; I have been told that some versions
|
||
;; of /bin/mail do not understand double-quotes in the .mailrc file. So you
|
||
;; should make sure your version does before including verbose addresses like
|
||
;; this. One solution to this, if you are on a system whose /bin/mail doesn't
|
||
;; work that way, (and you still want to be able to /bin/mail to send mail in
|
||
;; addition to emacs) is to define minimal aliases (without full names) in
|
||
;; your .mailrc file, and use define-mail-abbrev to redefine them when sending
|
||
;; mail from emacs; this way, mail sent from /bin/mail will work, and mail
|
||
;; sent from emacs will be pretty.
|
||
;;
|
||
;; Aliases in the mailrc file may be nested. If you define aliases like
|
||
;; alias group1 fred ethel
|
||
;; alias group2 larry curly moe
|
||
;; alias everybody group1 group2
|
||
;; Then when you type "everybody" on the To: line, it will be expanded to
|
||
;; fred, ethyl, larry, curly, moe
|
||
;;
|
||
;; Aliases may also contain forward references; the alias of "everybody" can
|
||
;; precede the aliases of "group1" and "group2".
|
||
;;
|
||
;; This code also understands the "source" .mailrc command, for reading
|
||
;; aliases from some other file as well.
|
||
;;
|
||
;; Aliases may contain hyphens, as in "alias foo-bar foo@bar"; word-abbrevs
|
||
;; normally cannot contain hyphens, but this code works around that for the
|
||
;; specific case of mail-alias word-abbrevs.
|
||
;;
|
||
;; To read in the contents of another .mailrc-type file from emacs, use the
|
||
;; command Meta-X merge-mail-abbrevs. The rebuild-mail-abbrevs command is
|
||
;; similar, but will delete existing aliases first.
|
||
;;
|
||
;; If you would like your aliases to be expanded when you type M-> or ^N to
|
||
;; move out of the mail-header into the message body (instead of having to
|
||
;; type SPC at the end of the abbrev before moving away) then you can do
|
||
;;
|
||
;; (add-hook
|
||
;; 'mail-mode-hook
|
||
;; (lambda ()
|
||
;; (define-key mail-mode-map [remap next-line] 'mail-abbrev-next-line)
|
||
;; (define-key mail-mode-map [remap end-of-buffer] 'mail-abbrev-end-of-buffer)))
|
||
;;
|
||
;; If you want multiple addresses separated by a string other than ", " then
|
||
;; you can set the variable mail-alias-separator-string to it. This has to
|
||
;; be a comma bracketed by whitespace if you want any kind of reasonable
|
