Multi-Line Triggers
 
I was looking for a way to do something like this:

#trigger {Trigger on this line that is known}
if the next like doesn't contain (this or this) do some formatting to the line with #sub.

I skimmed the helpfiles and couldn't find anything in the #events like receivedline or the sort and am I bit lost where to start.

Also assuming I'll need something to stop the trigger from firing on every line thereafter. I think the #waitsignal while accomplish this though.

#TRIGGER {first line} {}
#COND {*} {#IF (!%match(%line, {this|that})) {#SUB something}}

in the GUI, you can choose a new trigger state to create the condition.

It might be better to build the match components directly into the pattern of the second state. Depending on the complexity you might need to use a regex. Also you will probably want to limit the second state to matching only the next line using the WITHIN LINES trigger type.

#TRIGGER {known line} {}
#COND {{this|this}} {#SUB {some stuff}} {within|param=1}

More complex substitutions can be built by capturing parts of the line and testing the content, but again a regex might be needed for the more complex captures.

Code:

#TRIG {^***** Range (%d) *****} {
   #var range %1
   #CON {*} {
      #if (%match(%line,You scan {*}) {

      #UNCON {*}
   } {
      #SUB   {%line} {(@range @scanDir) %line}
   }
}


Getting illegal token error. I've tried escaping the "*"s in the triggers to no avail.

i suspect its the #UNCON command, that doesn't exist.
Also, #SUB only needs on parameter inside a trigger, giving it more will create a separate #TRIGGER, which I dont think you are wanting.
Also, since we are using a string instead of an anonymous variable inside %match, we should wrap it in quotes.

#TRIG {^~*~*~*~*~* Range (%d) ~*~*~*~*~*} {#var range %1}
#COND {^*$} {#if (%match(%line, "You scan")) {#SUB {(@range @scanDir) %line}}} {within|param=1}

Basically I am wanting to simplify this to something like:

Aha, that changes things

#TRIG {^~*~*~*~*~* Range (%d) ~*~*~*~*~*} {#var range %1}
#COND {^*$} {#if ((!%match(%line, "You scan") OR (%line=%null)) {
#SUB {(@range @scanDir) %line}
#STATE 1
}} {

Hmm... is the a line that appears when you are done scanning?
Cause I can see this getting stuck in the second state.
Adding that second #IF clause might help.

Thanks, Ill give it a shot.

I was just looking into #STATE. The helpfile is a bit ambiguous on it's use.

I feel like it will help with me keeping it fire on every single line. I need I way to turn it off once I'm done with it.

You will need to give this one trigger an ID if you want to be able to change its state from another trigger.
And I apparently edited it since you quoted it, sorry about that.
I'm not used to people being so on top of my suggestions.

Code:

#TRIG {^~*~*~*~*~* Range (%d) ~*~*~*~*~*} {
  #var range %1
  #COND {^*$} {
    #if (!%match(%line, "You scan")) {
      #SUB {(@range @scanDir) %line}
      #STATE 1
    } {
    #if (%match(%line,"<")) {#STATE 0} <--- my prompt turns it off
    }
  }
}

Is giving me this:
Quote:

You scan north.
***** Range 1 *****
(1 ) An elven citizen is calmly taking care of her tasks.
(1 )
You scan south.
You scan east.
***** Range 1 *****
(1 ) An imposing elven guardsman is keeping an eye out for trouble.
(1 ) An imposing elven guardsman is keeping an eye out for trouble.

(1 ) An imposing elven guardsman is keeping an eye out for trouble.
(1 ) A seductive sirine selling dresses from the Islands has set up a booth here.
(1 )
You scan west.
You scan up.
You scan down.


Basically I need to put a conditional for empty lines to gag. I'll also gag the ranges. But I think the substitutes are causing my trigger to not fire and set my Range variable... do substitutes work that way?

More tinkering gets me this:
Quote:

You scan north.
You scan south.
***** Range 1 *****
(1 south) Jorgen the jeweler is here inspecting some jewelry.

You scan east.
***** Range 1 *****
(1 east) A watchman patrols the streets of Udgaard.
A jaette man-at-arms is here protecting the city.

You scan west.
***** Range 1 *****
(1 west) A stray dog runs around the streets looking for something to chase.
A jaette soldier strides through the city.
A fire giant stands here with folded arms watching the bank transactions.
A fire giant stands here with folded arms watching the bank transactions.

You scan up.
You scan down.


With this code:
Code:

#TRIG {^~*~*~*~*~* Range (%d) ~*~*~*~*~*} {
  #var range %1
  #COND {^*$} {
    #if (!%match(%line, "You scan")) {
      #SUB {(@range @scanDir) %line}
      #STATE {scan} {1}
    } {
    #if (%match(%line,"<")) {#STATE {scan} 0}
    }
  }
}

Did you actually try my edited version with the #EXIT in there?

Code:
#TRIG {^~*~*~*~*~* Range (%d) ~*~*~*~*~*} {#var range %1}
#COND {^*$} {
  #IF (%line=%null) {#EXIT}
  #if (!%match(%line, "You scan") ) {
    #SUB {(@range @scanDir) %line}
    #STATE 1
  }
}

I'll give it a shot when I get a chance. Also thought of a custom function with a #switch and #default.

Tried your recommendation and got a parsing error.

The above code works but I suspect it's getting turned off prematurely somehow.

Odd... I got the same thing trying to enter it on the command line.... try entering it Via XML instead.
Make a new trigger, switch to the XML tab, and paste this over the current value:

Code:
<trigger priority="9940" id="994">
  <pattern>^~*~*~*~*~* Range (%d) ~*~*~*~*~*</pattern>
  <value>#var range %1</value>
  <trigger type="Within Lines" param="1">
    <pattern>^*$</pattern>
    <value>#IF (%line=%null) {#EXIT}
#if (!%match( %line, "You scan")) {
  #SUB {(@range @scanDir) %line}
  #STATE 1
  } </value>
  </trigger>
</trigger>


Edited to fix second pattern. This works on my end.

Retesting it... it seems to insert a space after the 1 in the #STATE command, removing that fixed it for me.

Not sure what the problem is. Doing similar to what my trigger did. Firing only on the first instance of {^*$}. Or so it would appear.

If you don't have an alternative, I may try gagging it all and making a list(s) then sorting/printing.

Boggling me why this isn't working.

I have the fix posted right after the code.... remove the space after the 1.
Did you delete your trigger, or are both still active?
I am guessing yours is giving the single results, and mine isnt firing because the space wasnt removed.

I removed the space. Both triggers give the same result. Firing on the first instance of {^*} only. Or at least appearing to.

The only difference is the XML trigger gave the above compiling errors after the first time the wildcard trigger fired.

Are line breaks added automatically after substitutes?

You need to use ^*$ not just ^* to force it to grab the whole line

^ is the start of line anchor
$ is the end of line anchor

I was getting odd results without using both.
Try disabling your trigger when you test mine, and vice versa.

Are you still getting those errors after the edit?
If so, go into the GUI settings editor for the trigger, then under the editor menu, you can check your syntax to find out what line the error is on.
