28 ;;; Commentary:
29
30 ;; The entry point of this code is
31 ;;
32 ;; mail-extract-address-components: (address)
33 ;;
34 ;; Given an RFC-822 ADDRESS, extract full name and canonical address.
35 ;; Returns a list of the form (FULL-NAME CANONICAL-ADDRESS).
36 ;; If no name can be extracted, FULL-NAME will be nil.
37 ;; ADDRESS may be a string or a buffer. If it is a buffer, the visible
38 ;; (narrowed) portion of the buffer will be interpreted as the address.
39 ;; (This feature exists so that the clever caller might be able to avoid
40 ;; consing a string.)
41 ;; If ADDRESS contains more than one RFC-822 address, only the first is
42 ;; returned.
43 ;;
44 ;; This code is more correct (and more heuristic) parser than the code in
45 ;; rfc822.el. And despite its size, it's fairly fast.
46 ;;
47 ;; There are two main benefits:
48 ;;
49 ;; 1. Higher probability of getting the correct full name for a human than
50 ;; any other package we know of. (On the other hand, it will cheerfully
51 ;; mangle non-human names/comments.)
52 ;; 2. Address part is put in a canonical form.
53 ;;
54 ;; The interface is not yet carved in stone; please give us suggestions.
55 ;;
56 ;; We have an extensive test-case collection of funny addresses if you want to
57 ;; work with the code. Developing this code requires frequent testing to
58 ;; make sure you're not breaking functionality. The test cases aren't included
59 ;; because they are over 100K.
60 ;;
61 ;; If you find an address that mail-extr fails on, please send it to the
62 ;; maintainer along with what you think the correct results should be. We do
63 ;; not consider it a bug if mail-extr mangles a comment that does not
64 ;; correspond to a real human full name, although we would prefer that
65 ;; mail-extr would return the comment as-is.
66 ;;
67 ;; Features:
68 ;;
69 ;; * Full name handling:
70 ;;
71 ;; * knows where full names can be found in an address.
72 ;; * avoids using empty comments and quoted text.
73 ;; * extracts full names from mailbox names.
74 ;; * recognizes common formats for comments after a full name.
75 ;; * puts a period and a space after each initial.
76 ;; * understands & referring to the mailbox name, capitalized.
77 ;; * strips name prefixes like "Prof.", etc.
78 ;; * understands what characters can occur in names (not just letters).
79 ;; * figures out middle initial from mailbox name.
80 ;; * removes funny nicknames.
81 ;; * keeps suffixes such as Jr., Sr., III, etc.
82 ;; * reorders "Last, First" type names.
83 ;;
84 ;; * Address handling:
85 ;;
86 ;; * parses rfc822 quoted text, comments, and domain literals.
87 ;; * parses rfc822 multi-line headers.
88 ;; * does something reasonable with rfc822 GROUP addresses.
89 ;; * handles many rfc822 noncompliant and garbage addresses.
90 ;; * canonicalizes addresses (after stripping comments/phrases outside <>).
91 ;; * converts ! addresses into .UUCP and %-style addresses.
92 ;; * converts rfc822 ROUTE addresses to %-style addresses.
93 ;; * truncates %-style addresses at leftmost fully qualified domain name.
94 ;; * handles local relative precedence of ! vs. % and @ (untested).
95 ;;
96 ;; It does almost no string creation. It primarily uses the built-in
97 ;; parsing routines with the appropriate syntax tables. This should
98 ;; result in greater speed.
99 ;;
100 ;; TODO:
101 ;;
102 ;; * handle all test cases. (This will take forever.)
103 ;; * software to pick the correct header to use (eg., "Senders-Name:").
104 ;; * multiple addresses in the "From:" header (almost all of the necessary
105 ;; code is there).
106 ;; * flag to not treat `,' as an address separator. (This is useful when
107 ;; there is a "From:" header but no "Sender:" header, because then there
108 ;; is only allowed to be one address.)
109 ;; * mailbox name does not necessarily contain full name.
110 ;; * fixing capitalization when it's all upper or lowercase. (Hard!)
111 ;; * some of the domain literal handling is missing. (But I've never even
112 ;; seen one of these in a mail address, so maybe no big deal.)
113 ;; * arrange to have syntax tables byte-compiled.
114 ;; * speed hacks.
115 ;; * delete unused variables.
116 ;; * arrange for testing with different relative precedences of ! vs. @
117 ;; and %.
118 ;; * insert documentation strings!
119 ;; * handle X.400-gatewayed addresses according to RFC 1148.

122 ;;
123 ;; Thu Feb 17 17:57:33 1994 Jamie Zawinski (jwz@netscape.com)

126 ;;
127 ;; Wed Feb 9 21:56:27 1994 Jamie Zawinski (jwz@netscape.com)
128 ;;
129 ;; * high-bit chars in comments weren't treated as word syntax
130 ;;

135 ;; Thu Dec 16 21:56:45 1993 Jamie Zawinski (jwz@netscape.com)
136 ;;
137 ;; * some more cleanup, doc, added provide
138 ;;
139 ;; Tue Mar 23 21:23:18 1993 Joe Wells (jbw at csd.bu.edu)
140 ;;
141 ;; * Made mail-full-name-prefixes a user-customizable variable.
142 ;; Allow passing the address as a buffer as well as as a string.
143 ;; Allow [ and ] as name characters (Finnish character set).
144 ;;
145 ;; Mon Mar 22 21:20:56 1993 Joe Wells (jbw at bigbird.bu.edu)
146 ;;
147 ;; * Handle "null" addresses. Handle = used for spacing in mailbox
148 ;; name. Fix bug in handling of ROUTE-ADDR-type addresses that are
149 ;; missing their brackets. Handle uppercase "JR". Extract full
150 ;; names from X.400 addresses encoded in RFC-822. Fix bug in
151 ;; handling of multiple addresses where first has trailing comment.
152 ;; Handle more kinds of telephone extension lead-ins.

161 ;; handling an unmatched ' in a name string. Enhanced recognition
162 ;; of when . in the mailbox name terminates the name portion.
163 ;; Narrowed conversion of . to space to only the necessary
164 ;; situation. Deal with VMS's stupid date stamps. Handle a unique
165 ;; way of introducing an alternate address. Fixed spacing bug I
166 ;; introduced in switching last name order. Fixed bug in handling
167 ;; address with ! and % but no @. Narrowed the cases in which
168 ;; certain trailing words are discarded.
169 ;;
170 ;; Sun Mar 21 21:41:06 1993 Joe Wells (jbw at bigbird.bu.edu)
171 ;;
172 ;; * Fixed bugs in handling GROUP addresses. Certain words in the
173 ;; middle of a name no longer terminate it. Handle LISTSERV list
174 ;; names. Ignore comment field containing mailbox name.
175 ;;
176 ;; Sun Mar 21 14:39:38 1993 Joe Wells (jbw at bigbird.bu.edu)
177 ;;
178 ;; * Moved variant-method code back into main function. Handle

189 ;;
190 ;; * Cleaned up some more. Release version 1.0 to world.

194 ;; * Cleaned up full name extraction extensively.
195 ;;
196 ;; Sun Feb 2 14:45:24 1992 Joe Wells (jbw at bigbird.bu.edu)
197 ;;
198 ;; * Total rewrite. Integrated mail-canonicalize-address into
