Question

I have an array @fields containing names for the tab-separated values in $record (it may have been populated from record 0 of the file, for instance).

The order of the array entries corresponds to the order of the values in the record.

I want to populate %hash with field => value entries for each value in the record.

Is there a one-liner to do this? I can’t figure out how to coordinate traversing the @fields and split(“\t”, $record) list concurrently.

Best I can come up with is

my %hash;
my @values = split("\t", $record);
for my $field (@fields) {
    my $value = shift @values;
    $hash{$field} = $value;
}

But I suspect there’s a simpler way to do it.

Thanks.

There is — it’s the hash slice notation:

@values = split /\t/, $record;
@hash{@fields} = @values;

or

@hash{@fields} = split /\t/, $record;
