hi,
i'm using aliasing from time to time.. i mean this :
local *var = \@array;
now my question is there any chance I can alias a var to another one out of the scope of the grammar Ex.:
our @array = qw(1 2 3 4);
my $grammar = q{
{ our @a }
start : rule1 rule2 ruleX
ruleX : 'keyword' /[a-z]+/ {
local *a = \@::{$item[2]};
print @a
}
......
}
this will print "1234".
(in our case
$item[2] is set to 'array'.)
ofcourse this work only inside the "ruleX". My question is how to alias in such a way so that the alias set in some of the rules is accessible to the whole grammar ?
After this question my next question is how can I pass a reference to the array I want to alias.. so that I can alias the array-alias to object internal data (not class global or main-globals).. i.e.
@a --points---> $$self{_array}
