After a bit of recent testing I found the suggested trigger further up matches too often.

This seems to work better:


<triggers>
  <trigger
   enabled="y"
   lines_to_match="15"
   match="You are carrying:\n(([ ]{5}.*\n)*)\n(?![ ]{5})\z"
   multi_line="y"
   regexp="y"
   send_to="2"
   sequence="100"
  >
  <send>Found %0</send>
  </trigger>
</triggers>

There is an extra \n before the last bit, which forces it to assert that it gets a newline followed by *not* 5 spaces, to signal the end of the inventory.

Test data:



You are carrying:
     a magic mushroom
     a torch
     a dragonskin
     a bag
     recall scroll

Without the \n it matched on each line of inventory.
