Parameters scope in triggers?
|
#TEMP {foo (*)} {
#VARIABLE tmp "aaa|bbb|ccc|ddd|eee"
#FORALL @tmp {
#SAY %1
}
}
In FORALL loop parameter %1 is from #TEMP parameter not #FORALL - how to make %1 get values from list?

#LOOP, #FORALL use the tracking variable %i. So you would want:
#TEMP {foo (*)} { #VARIABLE tmp "aaa|bbb|ccc|ddd|eee";#FORALL @tmp { #SAY %i }}
If you have loops in loops etc, you would have to save the
previous %i
#LOOP 2 {
#VAR FirstLoop_i %i
#LOOP 2 {
#ECHO First loop: @FirstLoop_i Second Loop: %i
}
}

You didnt understand my problem. In my case #SAY %1 won't output 'aaa', but will output 5 times string which triggered trigger (string from (*)).
So in my case %1 is not scoped from #FORALL but is scoped from #TEMP trigger - something wrong!?
PS. I'm proffesional developer and know many programing languages - zMud is only one script language which I know, but sometimes works, ekhm... strange
Best rgds,

That is because %1..%n is used to refer to values matched by the pattern of the trigger and that zMUD stores because you told it to do it. If you look at Ton's reply, you'll see that inside the #FORALL loop you need to use %i not %1 to refer to the current iteration. That is, it's:
#VARIABLE tmp "aaa|bbb|ccc|ddd|eee"
#FORALL @tmp {#SAY %i}
not:
#VARIABLE tmp "aaa|bbb|ccc|ddd|eee"
#FORALL @tmp {#SAY %1}
no matter if it is all by itself or inside a trigger/alias/macro/etc.

Yes - sorry for problem - I've just found this error by myself.
I'm using temp trigger in alias so each parameter I have to write as %%1 or %%i and this little embarassed me.
Now everything is ok.
