O wise monks, greetings. I'm trying to replace the values of a hash based on the keys matching a regex. Is there a more compact, one liner way of doing it, without using foreach and the braces ?
Most ideally I would want something like this:
$hash{/abc_(.*)_ghi/} = boom_$1
That should reassign all the 4 key-value pairs in the hash.
My current code:
use Data::Dumper;
my %hash = (
xxx_text10_yyy => 1,
xxx_text11_yyy => 1,
mmm_text12_nnn => 1,
mmm_text13_nnn => 1,
abc_text6_ghi => 1,
abc_text7_ghi => 1,
abc_text8_ghi => 1,
abc_text9_ghi => 1
);
print Dumper(\%hash);
foreach my $key (keys %hash)
{
$hash{$key} = "boom_$1" if ($key =~ /abc_(.*)_ghi/);
$hash{$key} = "doom_$1" if ($key =~ /mmm_(.*)_nnn/);
}
print Dumper(\%hash);
