a87bc2c2 | 1 | Add welcome message functionality. |
2 | ||
3 | client commands: | |
4 | user: | |
f49eea8e | 5 | /WELCOME [<server>] |
a87bc2c2 | 6 | shows welcome messages set, same is shown on connect |
f49eea8e | 7 | feature HIS_REMOTE controls whether ordinary users can request a listing from a remote server |
a87bc2c2 | 8 | |
9 | oper: | |
f49eea8e | 10 | /WELCOME [<server>] [[$][+]<N> :<message>] |
a87bc2c2 | 11 | to view welcome messages from a remote server |
12 | to set a local welcome message on this server or a remote server | |
f49eea8e | 13 | set a global welcome message (server *) |
14 | the $ prefix makes the server annouce the welcome message to its clients when setting | |
15 | the + prefix moves message in N and all after that one spot down, and inserts the new message | |
16 | in spot N, if there is no room, the last entry is deleted | |
17 | when an entry is cleared (no text), then all entries after it are moved on place up, so all empty | |
18 | spots are at the end | |
a87bc2c2 | 19 | |
20 | server: | |
f49eea8e | 21 | :<source> WE <target> [[$][+]<N> <timestamp> <who> :<text>] |
a87bc2c2 | 22 | who is who set the message, the server puts in the opername when a client sets it. |
f49eea8e | 23 | :<N> is a number 1 to WELCOME_MAX_ENTRIES - currently set at 10 (should be more than we ever need) |
a87bc2c2 | 24 | that means there is room for 10 local and 10 global entries |
