How to correctly use a GMCP Redirect.Window package
|
So I was poking around IRE's Achaea and came across the Redirect GMCP package. When enabled this allows Achaea to send Redirect.Window "windowname" commands. Achaea's builtin map uses this package in the following way (taken from the debugger):
| Code: |
<SB><201>Redirect.Window "map"<IAC><SE>
<textual map data here>
<SB><201>Redirect.Window "main"<IAC><SE>
|
So I thought I'd try to use this gmcp package to capture the map to a window in CMUD because hey, why not? I've tried a few things, none of which work. The following is the most 'obvious' method of doing it for me:
| Code: |
<trigger name="Redirect" type="GMCP" param="201" priority="100" id="10">
<pattern>Redirect.Window</pattern>
<value>#switch ( %gmcp.Redirect.Window )
("map") {
#clr "Map"
#c+ "Map"
}
("main") {
#c-
}
</value>
</trigger> |
When this trigger is executed I get the following in the main session window:
| Code: |
Capture text ON
Capture text OFF

So I can see the trigger is firing, but the #C+/- commands just toggle one after the other. I believe this is due to how CMUD actually processes these GMCP messages. It looks like CMUD is processing all the GMCP messages at once before it actually renders out the received text and not inline with the actual data received.

This seems more like design feature than bug to me but I'm still left with the question of how to use this GMCP package to capture the map data into a window. Is this even possible in CMUD with the GMCP method IRE has implemented here? |

Yes, this is how GMCP works unfortunately. GMCP is sent as "out of band" Telnet messages (the IAC SB stuff) and "out of band" messages are processed before any other text and there is no way to sync these messages with the text. You might send a message to Achaea to see if they can send their "Redirect Main" message is a separate network packet so that it doesn't get processed before the actual map data itself.
All of the GMCP stuff is still relatively new to both the clients and the MUDs so issues like this need to be worked out. So they should be willing to help you get this working. |

Yeah they follow this pattern for a lot of stuff. Comm channels too. Why they don't just include the channel text as the body of the gmcp data I haven't the faintest idea. I'll see how I can get in contact with IRE to get this fixed. Since you have a relationship with IRE maybe you could send them a quick email? Not trying to impose, just figure they would pay attention more coming from you.
