Debug

/debug [-cinpt] [N] [on|off|@window|filename] [identifier] Outputs raw server messages, both incoming and outgoing, to a debug.log file, or a custom @window.

Switches

Switch	Meaning
-c	turns off debugging and closes the associated custom @window
-i	the specified identifier before a debug line is logged. The return value of the identifier is used as the debug line.
-n	opens the custom @window minmized.
-p	turns word wrapping on.
-t	turns timestamping on.

Example on using a custom alias:

; we'll make an alias that we will use with /debug -i
alias debugoutput { 

  ; the debug line is actually $1, so we'll now tokenize it, so we can use $1 $1- etc.
  tokenize 32 $1 

  ; add a line into the debug window, $debug will return the name of the debug window that you created
  ; this will just replace those arrows <- and -> (which is $1 after the tokenize) with colored ones, -p in aline to wrap the text
  aline -p $debug $timestamp $replace($1, $&
    <-, $+($chr(3),10,<-,$chr(3)), $&
    ->, $+($chr(3),04,->,$chr(3)) $&
  ) $2- 
}

; now just open the debug window with /debug -i @debug debugoutput
