Zugg Software :: View topic - Script help plz: Capturing a line and populating a variable with it

Hi folks,

Short explanation: I need to capture a line and populate a variable with the contents so that it can be reported to a channel. The string will always be the room exits and will appear similar to, "[Exits: north east south (west)]" where west is a locked door. The variable name is @rmexits and I'd like to trigger the capture off of ^[Exits:

Any help appreciated.

#TR {^~[Exits: (*)~]} {rmexits=%1}

Assuming that you want to do the work, what part(s) are you having trouble with?

1)pattern.
a)You already know how to use ^ to match the beginning of the line.
b)Do you know how to use ~ to prevent CMud from interpreting special characters (in this case, [] and ())? All you do is ~[ and so on.
c)to match letters, spaces, and (), you can use the range pattern: [%w%s~(~)]
d)to capture the pattern to a %1...%99 variable so you can assign it to @rmexits, surround it with ()

2)code.
a)variable assignment. Easiest way is to use a=b syntax. A is equal to the variable name without the @. More complex examples (though not needed in this case), can be used with the #VARIABLE command.
