(jeffa) 3Re: Using list elements within lists contexts with the distributive properties of HTML shortcuts

Sure, i will discuss the a() shortcut and let you apply it to the others.

Each shortcut takes an optional reference to a list and distrubutes it across each element. That you know, but when you try to do this via:

a( {-href=>$_ }, \@list )

the default variable is not 'associated' with the list reference. Indeed, the enumeration of the elements is done outside of your scope.

The only way (that i know of) to 'associate' it is to use a loop instead:

for (@list) {
   print a({-href=>$_},$_);
}

# or
print a({-href=>$_},$_) for @list;

# or
print map {a({-href=>$_},$_) } @list;

Thanks again. The murk is thinning slowly, just rather more slowly than I would care to admit.	[reply]
