[LUA] io.read()

[shadowart]

When you create a custom channel in Xenobot you pass the constructor three parameters: channelName, textCallback, closeCallback.

The first is a string and is the name given to the channel you create. The last is a function that is called when the channel is closed.

The second, which is relevant to what you're looking for, is called any time any text is sent in the channel. It looks something like this:

function OnSpeak(channel, message)
   if (message == "ping") then
      channel:SendOrangeMessage("Channel", "Pong!")
   end
end

function OnClose() end --empty

local newChannel = Channel.New("Channel", OnSpeak, OnClose)

newChannel:SendOrangeMessage("Channel", "Hi!")

Considering his code examples I'm pretty sure he already knows that but finds it cumbersome to use as you have to turn your callback function into a finite-state machine.
