Zugg Software :: View topic - Is there a way to tell if I'm waiting at a prompt?

Posted: Thu Jan 17, 2008 10:50 pm

I have a situation where I'd only like to execute something if I'm sitting at a prompt waiting for more text from the mud. Is there a way to detect this somehow?

It's not that I want to execute it anytime I see a prompt, the situation is that an event (me hitting a macro) could occur at any time, ie when it's between prompts or when I'm sitting at the prompt. If I hit the macro and I'm sitting waiting at a prompt it should execute immediately, if I'm between prompts it should execute when I'm finished executing the prompt.

Right now I set a flag and then do a #send "" to force another prompt. This is semi-adequate but it introduces a delay to receive a new prompt before it is executed if I'm just waiting at the prompt.

What I'd love to be able to do is this:

#if (waiting at prompt) {Execute Immediately} {Set flag to execute at prompt}

Urm, not really that I know of but there is hope.

#if (%line =~ %dh blah blah that matches the prompt) {Assume that it was sent from the mud and execute the danged script.} {set the flag}

The problem being that things that you echo to the screen via print or say or echo show as coming from the mud.

Also #cr does the same as your #send

#show 1223h, 3456m e-
#if (%line=~"%dh, %dm %x") {#say Prompt} {#say Not Prompt}
#if (%line=~"%dh, %dm %x") {#say Prompt} {#say Not Prompt}

Sorry for only a theory...

How about this:
1) Catch each prompt with OnPrompt event and store event time in a variable (with %time(), probably). If you have prompt parser, place this check in it.
2) Make #FUNCTION DelayTest, which will check time diff between time value in variable and current time. Insert function call in your macro. If difference is greater than some predefined value (hard-coded or another variable), then execute you macro script, else abort.

I think I'd try to move the macro script into a multistate trigger (I believe you should be able to step into the #COND code by setting the #STATE in your existing MACRO) and then try to use some within or while logic to get it timed just right.

On a tangent on what Arde mentioned, I am trying to make a similar script that evaluates the time b/t the rounds for similar purposes. The mud usually sends prompt every 2 seconds, but on occasion it lags and ends up sending them in 1 second/3 second intervals. So trying to evaluate a delta time is a bit hard, I was thinking is there was a way to evaluate the latency from the mud it may be possible to add an additional check that will permit deviations from the 2 seconds if the server is being slow. Does anyone know a way or a variable that stores a form of ping information from the mud? or know a way to evaluate this.

Urm... Isn't a ping about the equivalent to sending a command and receiving a response? So make an alias that does some random command that does not require balance on your mud. Preferably one that other players cannot tell that you issued. Use #sendraw to send the command and set a variable to the time value that you sent the command. Then make a trigger that fires when your command is completed by the mud. Then display the differences in time. You could even gag the response if you really didn't want to see it.

Tada, you have pinged your mud.
