Hi, is it possible to assign a stringlist to match anything in the list in a string?
First i wanted to use regular expressions but i think this can't work.
The problem is i must find a changing substring like "Exet" and "Exit", tried "Ex?t"
but did not work, because i think its treated like a string and a normal questionmark
is interpreted.
{@Exits} as "Exit|Exet" did not work.

I think the next question i related to the first. I wanted to match a line for exit-keywords,
but not anything behind the keyword but specific words after the match like:

%match(%1, "Exits: (*)", @RExits)

Anything behind the Exits: is stored in the @RExits Variable but theres the problem,
the exit line says:

Exits: north, south AND east
I have a variable @directions=north|south|west..... in it.

How can i match only the real exits into the RExits variable?

Thanks ... @ MattLofton too ;)

In Regex \b[Exits\?]{4,5}\b is pretty close to what you want I think.
The problem I think you would run into is that it is too vague.

You could do it like this.

\b(?:Exit|Exet|Exits)\b

Can i use it like this, or do i have to activate "Regular Expression" flag?

#if (%pos("\b(?:Exit|Exet|Exits)\b",%1)) {#echo "Exit found"}{#echo "nothing"}

I get no message, but the exit is there?!

To only match real exits (I'm not sure why this would be necessary, unless you need other scripts beyond your #TAG triggers to access exits), you will need to process the @Rexits variable:

Rexits = %replace(%replace(@Rexits," and ","|"),", ","|")

There's no way to pick out just the exits themselves among a comma-and-AND-delimited list via trigger pattern, as patterns (even REGEX) rely on continuous blocks of text to define match/no match.

Thanks, i'll take the "false" strings out. I need the rooms for the #TAG part :) with your help in the other post but i thought it is not a beta problem and i posted it here.
