23 ;;; This file ensures that, when the point is in a To:, CC:, BCC:, or From:
|
|
|
24 ;;; field, word-abbrevs are defined for each of your mail aliases. These
|
|
|
25 ;;; aliases will be defined from your .mailrc file (or the file specified by
|
|
|
26 ;;; the MAILRC environment variable) if it exists. Your mail aliases will
|
|
|
27 ;;; expand any time you type a word-delimiter at the end of an abbreviation.
|
|
|
28 ;;;
|
|
|
29 ;;; What you see is what you get: no abbreviations will be expanded after you
|
|
|
30 ;;; have sent the mail, unlike the old system. This means you don't suffer
|
|
|
31 ;;; the annoyance of having the system do things behind your back -- if an
|
|
|
32 ;;; address you typed is going to be rewritten, you know it immediately,
|
|
|
33 ;;; instead of after the mail has been sent and it's too late to do anything
|
|
|
34 ;;; about it. You will never again be screwed because you forgot to delete an
|
|
|
35 ;;; old alias from your .mailrc when a new local user arrives and is given a
|
|
|
36 ;;; userid which conflicts with one of your aliases, for example.
|
|
|
37 ;;;
|
|
|
38 ;;; Your mail alias abbrevs will be in effect only when the point is in an
|
|
|
39 ;;; appropriate header field. When in the body of the message, or other
|
|
|
40 ;;; header fields, the mail aliases will not expand. Rather, the normal
|
|
|
41 ;;; mode-specific abbrev table (mail-mode-abbrev-table) will be used if
|
|
|
42 ;;; defined. So if you use mail-mode specific abbrevs, this code will not
|
|
|
43 ;;; adversely affect you. You can control which header fields the abbrevs
|
|
|
44 ;;; are used in by changing the variable mail-abbrev-mode-regexp.
|
|
|
45 ;;;
|
|
|
46 ;;; If auto-fill mode is on, abbrevs will wrap at commas instead of at word
|
|
|
47 ;;; boundaries; also, header continuation-lines will be properly indented.
|
|
|
48 ;;;
|
|
|
49 ;;; You can also insert a mail alias with mail-interactive-insert-alias
|
|
|
50 ;;; (bound to C-c C-a), which prompts you for an alias (with completion)
|
|
|
51 ;;; and inserts its expansion at point.
|
|
|
52 ;;;
|
|
|
53 ;;; This file fixes a bug in the old system which prohibited your .mailrc
|
|
|
54 ;;; file from having lines like
|
|
|
55 ;;;
|
|
|
56 ;;; alias someone "John Doe <doe@quux.com>"
|
|
|
57 ;;;
|
|
|
58 ;;; That is, if you want an address to have embedded spaces, simply surround it
|
|
|
59 ;;; with quotes. This is necessary because the format of the .mailrc file
|
|
|
60 ;;; bogusly uses spaces as address delimiters. The following line defines an
|
|
|
61 ;;; alias which expands to three addresses:
|
|
|
62 ;;;
|
|
|
63 ;;; alias foobar addr-1 addr-2 "address three <addr-3>"
|
|
|
64 ;;;
|
|
|
65 ;;; (This is bogus because mail-delivery programs want commas, not spaces,
|
|
|
66 ;;; but that's what the file format is, so we have to live with it.)
|
|
|
67 ;;;
|
|
|
68 ;;; If you like, you can call the function define-mail-alias to define your
|
|
|
69 ;;; mail-aliases instead of using a .mailrc file. When you call it in this
|
|
|
70 ;;; way, addresses are separated by commas.
|
|
|
71 ;;;
|
|
|
72 ;;; CAVEAT: This works on most Sun systems; I have been told that some versions
|
|
|
73 ;;; of /bin/mail do not understand double-quotes in the .mailrc file. So you
|
|
|
74 ;;; should make sure your version does before including verbose addresses like
|
|
|
75 ;;; this. One solution to this, if you are on a system whose /bin/mail doesn't
|
|
|
76 ;;; work that way, (and you still want to be able to /bin/mail to send mail in
|
|
|
77 ;;; addition to emacs) is to define minimal aliases (without full names) in
|
|
|
78 ;;; your .mailrc file, and use define-mail-alias to redefine them when sending
|
|
|
79 ;;; mail from emacs; this way, mail sent from /bin/mail will work, and mail
|
|
|
80 ;;; sent from emacs will be pretty.
|
|
|
81 ;;;
|
|
|
82 ;;; Aliases in the mailrc file may be nested. If you define aliases like
|
|
|
83 ;;; alias group1 fred ethel
|
|
|
84 ;;; alias group2 larry curly moe
|
|
|
85 ;;; alias everybody group1 group2
|
|
|
86 ;;; Then when you type "everybody" on the To: line, it will be expanded to
|
|
|
87 ;;; fred, ethyl, larry, curly, moe
|
|
|
88 ;;;
|
|
|
89 ;;; Aliases may also contain forward references; the alias of "everybody" can
|
|
|
90 ;;; preceed the aliases of "group1" and "group2".
|
|
|
91 ;;;
|
|
|
92 ;;; This code also understands the "source" .mailrc command, for reading
|
|
|
93 ;;; aliases from some other file as well.
|
|
|
94 ;;;
|
|
|
95 ;;; Aliases may contain hyphens, as in "alias foo-bar foo@bar"; word-abbrevs
|
|
|
96 ;;; normally cannot contain hyphens, but this code works around that for the
|
|
|
97 ;;; specific case of mail-alias word-abbrevs.
|
|
|
98 ;;;
|
|
|
99 ;;; To read in the contents of another .mailrc-type file from emacs, use the
|
|
|
100 ;;; command Meta-X merge-mail-aliases. The rebuild-mail-aliases command is
|
|
|
101 ;;; similar, but will delete existing aliases first.
|
|
|
102 ;;;
|
|
|
103 ;;; If you want multiple addresses separated by a string other than ", " then
|
|
|
104 ;;; you can set the variable mail-alias-separator-string to it. This has to
|
|
|
105 ;;; be a comma bracketed by whitespace if you want any kind of reasonable
|
|
|
106 ;;; behaviour.
|
|
|
107 ;;;
|
|
|
108 ;;; Some versions of /bin/mail append the contents of multiple definitions of
|
|
|
109 ;;; the same alias together, so that
|
|
|
110 ;;; alias group one two three
|
|
|
111 ;;; alias group four five
|
|
|
112 ;;; would define "group" as "one two three four five" instead of "four five".
|
|
|
113 ;;; This code does *not* support that syntax, because it's a horrible syntax
|
|
|
114 ;;; and isn't worth the effort or added code complexity. (So there.)
