-----------------------------------------------------------
without the ----
Now I just want to be able to type 'army status *' ie 'army status pikemen' or whatever and just see those lines, which means excluding every other line that doesn't begin with that wildcard. Okay, here is my simple set the variable alias, works fine.

<aliases>
<alias
match="as *"
enabled="y"
expand_variables="y"
send_to="12"
ignore_case="y"
sequence="100"
>
<send>SetVariable "astat", "%1"
send "army status"</send>
</alias>
</aliases>

Okay, I set a variable named 'astat' and send the command to the mud.

But when I try to make a simple trigger idea I have no idea how to do so successfully.
I tried different sorts, made sure to expand the variable, had regular expression checked when I need it, etc.
Sort of like

(?!@astat) [(.*)] training: (.*) dailycost: (.*) morale: (.*) [(.*)]

Now I got the variable to match successfully once and be excluded, but I can't figure out how to omit anything BUT the variable.

So fustrating blah. :)

You were on the right track. This seems to work for me:


<triggers>
 <trigger
 custom_colour="2"
 enabled="y"
 expand_variables="y"
 match=
"(?!@astat)(.*?) \[(.*?)\] training: (.*?) dailycost: (.*?) morale: (.*?) \[(.*?)\]"
 omit_from_output="y"
 regexp="y"
 sequence="100"
 >
 </trigger>
</triggers>

The change was that the negative look-ahead assertion you had does not consume characters, so I had to add (.*?) after it.

Also, putting \ in front of the brackets, otherwise they have a different meaning.

Works perfectly.
I had read a previous forum thread on the purpose of (.*? ) vs (.*) and didn't think it would have helped me :D
thanks.

Nah, it doesnt really. Well, except for specific cases, the big thing he changed was the escaping of the brackets.
