[irc/quakenet/snircd-patchqueue.git] / welcome.patch
1 Add welcome message functionality.
2
3 client commands:
4 user:
5 /WELCOME
6 shows welcome messages set, same is shown on connect
7
8 oper:
9 /WELCOME [<target>] [[!]<name> :<message>]
10 to view welcome messages from a remote server
11 to set a local welcome message on this server or a remote server
12 set a global welcome message (target *)
13 the ! prefix makes the server annouce the welcome message to its clients when setting
14
15 server:
16 :<source> WE <target> [[!]<name> <timestamp> <who> :<text>]
17 who is who set the message, the server puts in the opername when a client sets it.
18 :<name> is a number 1 to WELCOME_MAX_ENTRIES - currently set at 10 (should be more than we ever need)
19 that means there is room for 10 local and 10 global entries
20
21 STATS W/welcome (/STATS w/userload made case sensitive)
22 :server 230 nick W Name Target Who Timestamp :Message
23 :server 227 nick W 1 * opername 1233072583 :Latest news: testing this welcome patch :)
24 :server 227 nick W 2 * opername 1233072583 :
25 :server 227 nick W 1 servername opername 1233072590 :This is a test server, expect restarts.
26 :server 219 nick W :End of /STATS report
27
28 listing welcomes or on connect:
29 :server NOTICE nick :[QuakeNet] Latest news: testing this welcome patch :)
30 :server NOTICE nick :[server] This is a test server, expect restarts.
31
32 announcement is done by a notice by the local server to $* with the same message
33 format as for listing welcome messages.
34 :server NOTICE $* :[QuakeNet] Latest news: testing this welcome patch :)
35 :server NOTICE $* :[server] This is a test server, expect restarts.
