I am trying to only get the first sentance in a room description for a trigger.
If I use:
^*.
It grabs the whole paragraph. I'm not sure how to use %w since I don't know how many words may be in the sentance.
How can I do my expression so it only grabs the first sentance which stops on the first period?

If you only have letters and spaces in the sentences and they all end with periods, a pattern of ^([a-z].) should work. If, however, your sentences sometimes have punctuation in them or end in things other than periods (like exclamation points or question marks), you'll need something more robust like:

^([a-z ()~~`@#$%^&*-_+={}[~]|:;"'<>,/]{.|?|!})

Both of these methods result in the first sentence being in %1 where you can do whatever you want with it.

Another solution is to pull in the first line regardless and then use %pos and %left to get only the part up to the first period. Like:

#TRIGGER {^(*)$} {#VAR FirstSentence %left("%1", %pos("%1", "."))}
