For a) "highlight/notify about text typed by a specific user" (not specific text), there's the "match on nickname" option. Matchtext is the nick, or multiple nicks.
Alternatively, you may use the following method to match "FriendsNick" and "FriendsNick|afk" etc (like "Friendsnick*"):
- enter in the matchtext editbox:
\QFriendsNick
\E.*- check the "regex" box
For c) "highlight/notify about text containing your nick", theres the "match on text" option. Simply use
$me for matchtext.
b) Can be scripted like:
; if someone types something in PM
on *:text:*:?: {
; flash the mirc icon (only if mirc is not the active app)
flash -r $nick said in PM: $1-
; play a certain soundfile
splay path-to-a-soundfile.wav/.mp3
}
