Hey!

I've set up a chat connection using
ChatAcceptCalls(23)

and

ChatCall("localhost", 23)

Once that is done, I try to iterate through all the connection id's we have and:
ChatMessage(id, 7, "Test")

That message is never received on the other user's OnPluginChatMessage. I'm currently connecting to my own computer from one mushclient to another. I'm using python-scripting for this.

Is your router/firewall blocking it?

It shouldn't, since it allows connections to go through. It also allows disconnect-messages to go through. Everything is set up fine except the passing of messages.

You found a bug, introduced in version 4.62 which had a lot of code cleanups for plugins.

Due to the way it was calling the plugins it assumed that your attempt to send a message was being rejected. You may have also noticed that even without using plugins no messages were appearing when you started chat sessions.

Fixed, I hope, in version 4.65

I think you managed to solve the bug Nick, awesome!

However, directly afterwards I think I found another bug.

My client (not the server) crashes upon connecting to the server.

I can actually see the log though:
Calling server at 127.0.0.1 port 23
Session established to localhost.

And then it crashes :/

Want me to supply the code?

I narrowed down the crash.

It's when I add this code:


def OnPluginChatDisplay(message, text):
	world.Note("OnPluginChatDisplay, message: " + str(message) + " text : " + str(text))
	return True

OnPluginChatMessage seems to work much better though.

Try returning 0, or alternatively, 1.

Something in combination with Python, MUSHclient and the WSH means random errors if you return certain values. For example, in the past I have experienced crashes when not sending a return value back, but setting an explicit 0 return magically fixed it.

Whether it is a bug in Python, a bug in MUSHclient, or some weird no-mans-land of developers reading the APIs differently, I don't know, but that might very likely fix it.

But for now, try to stick to ints. And strings for callbacks wanting strings back.

Yeah that seems to solve it.

I don't understand why one function works with booleans while the other require ints?

The partial answer is that the hard-coded calls use the type definitions in the .ODL file, for example:


[id(188)] long ChatGroup(BSTR Group, BSTR Message, BOOL Emote);


Now in this case I presume Python would enforce that you get back a long and not something else.

But the plugin callbacks use a "generic" caller (one that takes a VARIANT result I think) so they are more accepting of the data type you return. However I think Python still requires *some* sort of returned result, whereas other script languages may default to a NULL variant if you don't supply anything explicitly.

To be honest, I find the WSH interface quite confusing. Finding documentation on it is hard enough.
