Here is an example line:

Obvious exits are south, up, west and east.

I'm trying to make it so that %1 = south, %2 = up, ...

The exits can be anything, not just north, south, east, west, etc.
And the number of exits can change (obviously).

I can do this with multiple triggers (one for every exit number). But I am sure this can be done in a single regular expression, but it is escaping me.

Any ideas? I tried searching the forum, but I had no luck.

It can also be done with a simple zmud trigger, well it wont make them %1...%2 you can use %item to use them

#TRIGGER "exits" {Obvious exits are (*).} {
#VAR Exits {%replace(%replace("%1"," and ","|"),", ","|")}
#SAY first exit is %item(@exits,1)
}

Oh, very clever, thank you. That will do. I'm making a trigger to assign the first irregular exit to a keypad key, like /. So everytime you enter a room, it parses that exits, finds the first one that isn't n, s, e, w.... etc.
