snircdumodescheckisanoper: check IsAnOper() (local or global) instead of IsOper(...

[irc/quakenet/snircd-patchqueue.git] / welcome.patch

Add welcome message functionality.

client commands:
user:
/WELCOME
shows welcome messages set, same is shown on connect

oper:
/WELCOME [<target>] [[!]<name> :<message>]
to view welcome messages from a remote server
to set a local welcome message on this server or a remote server
set a global welcome message (target *)
the ! prefix makes the server annouce the welcome message to its clients when setting

server:
:<source> WE <target> [[!]<name> <timestamp> <who> :<text>]
who is who set the message, the server puts in the opername when a client sets it.
:<name> is a number 1 to WELCOME_MAX_ENTRIES - currently set at 10 (should be more than we ever need)
that means there is room for 10 local and 10 global entries

STATS W/welcome (/STATS w/userload made case sensitive)
:server 230 nick W Name Target Who Timestamp :Message
:server 227 nick W 1 * opername 1233072583 :Latest news: testing this welcome patch :)
:server 227 nick W 2 * opername 1233072583 :
:server 227 nick W 1 servername opername 1233072590 :This is a test server, expect restarts.
:server 219 nick W :End of /STATS report

listing welcomes or on connect:
:server NOTICE nick :[QuakeNet] Latest news: testing this welcome patch :)
:server NOTICE nick :[server] This is a test server, expect restarts.

announcement is done by a notice by the local server to $* with the same message
format as for listing welcome messages.
:server NOTICE $* :[QuakeNet] Latest news: testing this welcome patch :)
:server NOTICE $* :[server] This is a test server, expect restarts.
