26 ;;; Commentary:
28 ;; This file ensures that, when the point is in a To:, CC:, BCC:, or From:
29 ;; field, word-abbrevs are defined for each of your mail aliases. These
30 ;; aliases will be defined from your .mailrc file (or the file specified by
31 ;; `mail-personal-alias-file') if it exists. Your mail aliases will
32 ;; expand any time you type a word-delimiter at the end of an abbreviation.
33 ;;
34 ;; What you see is what you get: if mailabbrev is in use when you type
35 ;; a name, and the name does not expand, you know it is not an abbreviation.
36 ;; However, if you yank abbreviations into the headers
37 ;; in a way that bypasses the check for abbreviations,
38 ;; they are expanded (but not visibly) when you send the message.
39 ;;
40 ;; Your mail alias abbrevs will be in effect only when the point is in an
41 ;; appropriate header field. When in the body of the message, or other
42 ;; header fields, the mail aliases will not expand. Rather, the normal
43 ;; mode-specific abbrev table will be used if
44 ;; defined. So if you use mail-mode specific abbrevs, this code will not
45 ;; adversely affect you. You can control which header fields the abbrevs
46 ;; are used in by changing the variable mail-abbrev-mode-regexp.
47 ;;
48 ;; If auto-fill mode is on, abbrevs will wrap at commas instead of at word
49 ;; boundaries; also, header continuation-lines will be properly indented.
50 ;;
51 ;; You can also insert a mail alias with mail-abbrev-insert-alias
52 ;; (bound to C-c C-a), which prompts you for an alias (with completion)
53 ;; and inserts its expansion at point.
54 ;;
55 ;; This file fixes a bug in the old system which prohibited your .mailrc
56 ;; file from having lines like
57 ;;
58 ;; alias someone "John Doe <doe@quux.com>"
59 ;;
60 ;; That is, if you want an address to have embedded spaces, simply surround it
61 ;; with double-quotes. This is necessary because the format of the .mailrc
62 ;; file bogusly uses spaces as address delimiters. The following line defines
63 ;; an alias which expands to three addresses:
64 ;;
65 ;; alias foobar addr-1 addr-2 "address three <addr-3>"
66 ;;
67 ;; (This is bogus because mail-delivery programs want commas, not spaces,
68 ;; but that's what the file format is, so we have to live with it.)
69 ;;
70 ;; If you like, you can call the function define-mail-abbrev to define your
71 ;; mail aliases instead of using a .mailrc file. When you call it in this
72 ;; way, addresses are separated by commas.
73 ;;
74 ;; CAVEAT: This works on most Sun systems; I have been told that some versions
75 ;; of /bin/mail do not understand double-quotes in the .mailrc file. So you
76 ;; should make sure your version does before including verbose addresses like
77 ;; this. One solution to this, if you are on a system whose /bin/mail doesn't
78 ;; work that way, (and you still want to be able to /bin/mail to send mail in
79 ;; addition to emacs) is to define minimal aliases (without full names) in
80 ;; your .mailrc file, and use define-mail-abbrev to redefine them when sending
81 ;; mail from emacs; this way, mail sent from /bin/mail will work, and mail
82 ;; sent from emacs will be pretty.
83 ;;
84 ;; Aliases in the mailrc file may be nested. If you define aliases like
85 ;; alias group1 fred ethel
86 ;; alias group2 larry curly moe
87 ;; alias everybody group1 group2
88 ;; Then when you type "everybody" on the To: line, it will be expanded to
89 ;; fred, ethyl, larry, curly, moe
90 ;;
91 ;; Aliases may also contain forward references; the alias of "everybody" can
92 ;; precede the aliases of "group1" and "group2".
93 ;;
94 ;; This code also understands the "source" .mailrc command, for reading
95 ;; aliases from some other file as well.
96 ;;
97 ;; Aliases may contain hyphens, as in "alias foo-bar foo@bar"; word-abbrevs
98 ;; normally cannot contain hyphens, but this code works around that for the
99 ;; specific case of mail-alias word-abbrevs.
100 ;;
101 ;; To read in the contents of another .mailrc-type file from emacs, use the
102 ;; command Meta-X merge-mail-abbrevs. The rebuild-mail-abbrevs command is
103 ;; similar, but will delete existing aliases first.
104 ;;
105 ;; If you would like your aliases to be expanded when you type M-> or ^N to
106 ;; move out of the mail-header into the message body (instead of having to
107 ;; type SPC at the end of the abbrev before moving away) then you can do
108 ;;
109 ;; (add-hook
110 ;; 'mail-mode-hook
111 ;; (lambda ()
112 ;; (define-key mail-mode-map [remap next-line] 'mail-abbrev-next-line)
113 ;; (define-key mail-mode-map [remap end-of-buffer] 'mail-abbrev-end-of-buffer)))
114 ;;
115 ;; If you want multiple addresses separated by a string other than ", " then
116 ;; you can set the variable mail-alias-separator-string to it. This has to
117 ;; be a comma bracketed by whitespace if you want any kind of reasonable
118 ;; behavior.
