1Hi!
2
3this is vchat-client, a GPLed (SSL) client for the vchat protocol.
4
5You can get the most recent version of vchat-client via CVS, e.g:
6
7cvs -d:pserver:anonymous@pulse.flatline.de:/home/cvsroot login
8cvs -z3 -d:pserver:anonymous@pulse.flatline.de:/home/cvsroot co vchat-client
9
10(press return at password prompt)
11
12no autoconf yet, sorry. required libs:
13
14openssl (0.9.6+ preferred)
15readline (4.2+ preferred)
16ncurses (5.2 preferred)
17
18please adjust the Makefile according to your need, then run 'make' to compile,
19./vchat-client to start the binary. nope, I don't have any intention to use
20autoconf for this hack.
21
22run 'fakeroot make -f debian/rules binary' to build a debian package from the
23source.
24
25Keyboard commands:
26
27^J - clear private window
28^O - clear channel window
29^L - redraw screen
30^F - scroll window up
31^B - scroll window down
32^R - change active scrolling window
33 (see rightmost character of topic/console lines)
34^T - shrink private window size
35^G - grow private window size
36^X - toggle private window
37 (pops up on private messages)
38TAB - nick completion
39
40We also do provide a set of IRC like / - commands, there are:
41
42/CONFIG - not implemented yet, but will be used for configuration
43/QUIT reason - issue .x reason
44/USER regex - list users matching regex
45/FLT C regex - add regex to filter list... read ./filters for details
46/RMFLT regex|id - remove filter regex or id from filter list
47/LSFLT (C) - list all filter rules (matching C)
48/CLFLT (C) - remove all filter rules (matching C)
49/M(SG) user msg - issue .m user msg
50/LH - print hilitelist
51/ME action - issue .a action
52
53if you want to use an own window for messages set "messages" to a value in
54~./vchat/config ..
55
56if you want to use an SSL certificate with the default configuration you need
57to put the key in ~/.vchat/key and the certificate in ~/.vchat/cert, both in
58PEM format. You can generate a key and a certificate by calling vchat-keygen,
59but the server you connect needs to know the anon CA provided by vchat-keygen,
60which currently isn't the case anywhere.
61
62FILES:
63
64 README - you're reading it.
65 TODO - list of things to do
66 vchat-client.c - main() and utility functions
67 vchat-config.h - configuration defaults
68 vchat-keygen - key generator with anon CA - server support required
69 vchat-messages.h - server messages <-> function correlation
70 vchat-protocol.c - handling of server connection & messages
71 vchat-ui.c - user-interface and readline handling
72 vchat-user.c - userlist handling
73 vchat.h - global structures and functions
74
75everything should be self-explantory, but please don't refrain to ask and/or
76give bug reports, feature requests, hints and tricks, etc etc ..

1vchat-client now offers a new model of shaping your messages:
2Filters.
3
4Filters can have different colours, where [0-9] stand for
5colour pairs, certain letters of [a-zA-Z] mean character
6attributes. The two "special colours" [+-] are used for
7black/whitelisting your messages, from now on called
8ignore/zoom.
9
10While the alphanumeric colours are used to highlight the
11regex associated with them, the latter case may be used
12to select some of the messages from your scrollback buffer.
13
14This may mean - regex "all but those messages containing
15the regex" or + regex "only those messages containing the
16regex".
17
18When you have ignore regexes, zooming always supersedes
19ignorance, i.e. a message that once is declared as white-
20listed wont be ignored.

323<para>if you want to use an SSL certificate with the default configuration you need
324to put the key in ~/.vchat/key and the certificate in ~/.vchat/cert, both in
325PEM format. You can generate a key and a certificate by calling vchat-keygen,
326but the server you connect needs to know same anon CA provided by
327vchat-keygen, which currently isn't supported anywhere.</para>
328
329<para>to upload your certificate use nick-request.pl from the vchat-server
330source available at ftp://vchat.vaxbusters.org. Thisfor at least one of
