Is there any fast way of testing a line to see it matches any patterns within a list variable.

I know it's possible to do this using something like this:

#forall @ListVar {#if %pos(%i,%line) {#echo Match}}

The problem is that this is too slow. I know it's possible to test this a lot faster using a trigger such as:

#trig {@ListVar} {#echo match}

This is really very fast, probably due to zmud's trigger optimizations. What im after is something like a function version of a trigger..

like for example:
%trig("%line","@ListVar")

This would return a 1 or a 0 or somesuch, and it would do it in the same way that a trigger does the test, without looping through a #forall statement.

Is there anything like this already?
I haven't been able to include list variables in %pos or %match funcitons as yet.

Thanks.

Nope, you will simply have to use a loop of some kind. %match() would have been the exact thing you were asking for but currently it either is not designed to handle stringlist patterns or there's a bug preventing such.

Ah. It's interesting how everytime I post on here I seem to realise a different angle to approach the problem with.

The issue was resolved by using two triggers. The first trigger is exactly as above: #trig {@ListVar} and it basically just parses the %line to a variable. The second trigger is my main one, which then compares that the %line in that trigger matches the %line in the previous trigger. This effectively tests for large lists within any line. The only pre-requisite is to have the settings sorted by None and make sure that the first trigger is executed before the second one.

Of course the bad thing is that now i have an extra trigger that is always on and continually writes to a temporary variable. But at the moment it seems a small price to pay for increasing the efficiency in the second trigger.

Thanks for info on %match, you've saved me hours of trying to get it to work with List Vars.
