Hi, I am trying to capture the room title line. Here is one from my mud:
Inside the East Gate of Midgaard [ e w ]

Here is the trigger that I thought should work: (*) ~[ * ~]$
All I am getting is the first word of the room title. So when I check the capture variable for the above room, I only get the value "Inside".
BTW, I need to force the match at the end of the line because of my prompt which ends in [available exits]> .
What am I doing wrong?
Thanks,
Boca

Actually, I think you might be getting it all, but you're looking at the variable incorrectly. Try surrounding the variable in quotes or the curly braces.

Thanks for the suggestion, I could not get it to give more than the first word using the * . When I tried quotes or brackets:
('*') or ({*0} I did not get any match at all - perhaps I misunderstood what you meant.
But, I did get this to work which used your suggestion:
(&{where}) ~[ * ~]$
so I am all set.

Thanks,

You misunderstood Matt. What was meant is that it seems that when you were assigning the %1 to the variable, you didn't use quotes or curly braces. Since what zMUD does is just expand %1, when %1 contains more than one word, it can produce unexpected results when used in a function or command. Example, suppose you have this trigger:
You get a (*) from the container.

In the trigger you do this:
#VAR item %1

And you receive from the MUD:
You get a dark obsidian sword from the container.

@item will now contain the word darl and nothing else because when zMUD expands it, all the other words are interpreted as additional parameters to the #VAR command. If, instead, you do this:
#VAR item "%1"

or:
#VAR item {%1}

When zMUD expands it, the quotes or parameters will let know zMUD that it is just one argument that should all be entered into the variable.
