0f965ba3 30;; This file ensures that, when the point is in a To:, CC:, BCC:, or From:
b578f267
EN
31;; field, word-abbrevs are defined for each of your mail aliases. These
32;; aliases will be defined from your .mailrc file (or the file specified by
f6babbac 33;; `mail-personal-alias-file') if it exists. Your mail aliases will
b578f267
EN
34;; expand any time you type a word-delimiter at the end of an abbreviation.
35;;
36;; What you see is what you get: if mailabbrev is in use when you type
37;; a name, and the name does not expand, you know it is not an abbreviation.
38;; However, if you yank abbreviations into the headers
39;; in a way that bypasses the check for abbreviations,
40;; they are expanded (but not visibly) when you send the message.
41;;
42;; Your mail alias abbrevs will be in effect only when the point is in an
43;; appropriate header field. When in the body of the message, or other
44;; header fields, the mail aliases will not expand. Rather, the normal
fba75b6b 45;; mode-specific abbrev table will be used if
b578f267
EN
46;; defined. So if you use mail-mode specific abbrevs, this code will not
47;; adversely affect you. You can control which header fields the abbrevs
48;; are used in by changing the variable mail-abbrev-mode-regexp.
49;;
50;; If auto-fill mode is on, abbrevs will wrap at commas instead of at word
51;; boundaries; also, header continuation-lines will be properly indented.
52;;
85d0e9ed 53;; You can also insert a mail alias with mail-abbrev-insert-alias
b578f267
EN
54;; (bound to C-c C-a), which prompts you for an alias (with completion)
55;; and inserts its expansion at point.
56;;
57;; This file fixes a bug in the old system which prohibited your .mailrc
58;; file from having lines like
59;;
60;; alias someone "John Doe <doe@quux.com>"
61;;
62;; That is, if you want an address to have embedded spaces, simply surround it
63;; with double-quotes. This is necessary because the format of the .mailrc
64;; file bogusly uses spaces as address delimiters. The following line defines
65;; an alias which expands to three addresses:
66;;
67;; alias foobar addr-1 addr-2 "address three <addr-3>"
68;;
69;; (This is bogus because mail-delivery programs want commas, not spaces,
70;; but that's what the file format is, so we have to live with it.)
71;;
72;; If you like, you can call the function define-mail-abbrev to define your
73;; mail aliases instead of using a .mailrc file. When you call it in this
74;; way, addresses are separated by commas.
75;;
76;; CAVEAT: This works on most Sun systems; I have been told that some versions
77;; of /bin/mail do not understand double-quotes in the .mailrc file. So you
78;; should make sure your version does before including verbose addresses like
79;; this. One solution to this, if you are on a system whose /bin/mail doesn't
80;; work that way, (and you still want to be able to /bin/mail to send mail in
81;; addition to emacs) is to define minimal aliases (without full names) in
82;; your .mailrc file, and use define-mail-abbrev to redefine them when sending
83;; mail from emacs; this way, mail sent from /bin/mail will work, and mail
84;; sent from emacs will be pretty.
85;;
86;; Aliases in the mailrc file may be nested. If you define aliases like
87;; alias group1 fred ethel
88;; alias group2 larry curly moe
89;; alias everybody group1 group2
90;; Then when you type "everybody" on the To: line, it will be expanded to
91;; fred, ethyl, larry, curly, moe
92;;
93;; Aliases may also contain forward references; the alias of "everybody" can
94;; precede the aliases of "group1" and "group2".
95;;
96;; This code also understands the "source" .mailrc command, for reading
97;; aliases from some other file as well.
98;;
99;; Aliases may contain hyphens, as in "alias foo-bar foo@bar"; word-abbrevs
100;; normally cannot contain hyphens, but this code works around that for the
101;; specific case of mail-alias word-abbrevs.
102;;
103;; To read in the contents of another .mailrc-type file from emacs, use the
104;; command Meta-X merge-mail-abbrevs. The rebuild-mail-abbrevs command is
105;; similar, but will delete existing aliases first.
106;;
107;; If you would like your aliases to be expanded when you type M-> or ^N to
108;; move out of the mail-header into the message body (instead of having to
109;; type SPC at the end of the abbrev before moving away) then you can do
110;;
111;; (add-hook
bde4c7ce 112;; 'mail-mode-hook
c0df1972 113;; (lambda ()

117;; If you want multiple addresses separated by a string other than ", " then
118;; you can set the variable mail-alias-separator-string to it. This has to
119;; be a comma bracketed by whitespace if you want any kind of reasonable
120;; behaviour.
