 -- Continuing our Dissector example at [1], let's say we wanted to print the value
 -- of `foo.str` for packets whose `foo.num` field is >= sqrt(5) (I picked a
 -- condition that couldn't already be achieved with display filters).
 --
 -- This Wireshark Lua script implements a listener for this purpose.

 -- 1. Declare the tap with the `Listener()` function
 local tap = Listener.new(nil, 'foo')
 
 -- 2. Declare field extractors to pull values of named fields from the current packet
 local f_str = Field.new('foo.str')
 local f_num = Field.new('foo.num')
 
 -- 3. Declare the tap's packet function
 function tap.packet(pinfo, buf)
 
 	-- check if at least one instance of foo.num is >= sqrt(5)
 	local gt_sqrt5 = false
 	for _,v in ipairs({ f_num() }) do
 		if v >= math.sqrt(5) then
 			gt_sqrt5 = true
 			break
 		end
 	end
 
 	if gt_sqrt5 then
 		-- print all instances of foo.str from the current packet
 		for _,v in ipairs({ f_str() }) do
-			print(pinfo.number, 'foo.str', v)
+			info(pinfo.number..'foo.str'..v)
 		end
 	end
