LiveScratcher.PlusCom

[TheBlasphemer]

Used to lay a (string-only) bridge between Plus! and LiveScratcher scripts.
in LiveScratcher call:

JAVASCRIPT Code

function onReceive(txt) {
return "NOTIMPL";
}
function onClosed() {
}
function onConnect(channel) {
channel.onReceive=onReceive;
channel.onClosed=onClosed;
}
PlusCom.register("name",onConnect);

With a callback function taking one argument (the created channel object).
Then in Plus! call:

JAVASCRIPT Code

var channel={
OnReceive:function(text) {return "NOTIMPL";},
OnClose:function() {}
};
Interop.Call("PlusCom.dll","Connect","name",channel);

This will call the "onConnect" callback with a newly created channel object.
The channel object has 2 methods:

• close or Close (first from LS, second from Plus!)
• send or Send
  

and 2 callbacks:

• onReceive or OnReceive
• onClosed or OnClosed
  

Events from Plus! should be set before Connect call (so that send from the LS callback works), Events from LiveScratcher should be set as soon as possible in the callback function. Events can be changed later on.

Note: the return value from onReceive or OnReceive will be converted to a string and returned from send or Send on the other side.
