Hi list,
given an array reference in a hash, how can I append an item to the end of
that array? Or find the length so that I can assign it using $ref-[$n]
type notation?
I have tried various comboes...
$hash{$key} holds a reference to an array in the sample code presented.
*) push(@$hash{$key},$item);
# ---> gives an error message, not a valid array for push
*) $hash{$key}->[scalar $hash{$key}]=$item;
#no good either
*) $hash{$key}->[scalar @$hash{$key}]=$item;
#no good
*) $hash{$key}->[scalar @{[$hash{$key}]}]=$item;
#no good either
The following notation turned out to work though...
my $r=$hash{$key};
my @l=@$r;
$hash{$key}->[scalar @l]=$item;
...but I dont like the idea of _having_ to use those extra lines of code
there, there should be a way to append an item to a list reference in
one single operation.
Regards,
Torbjørn Lindahl
