Re: Replacing If Elsif Else with Hash

[frozenwithjoy]

in reply to Replacing If Elsif Else with Hash

This will return 'grey' if you use a severity not defined in the hash:

my %bkcolor = (
    'Extreme'  => 'red',
    'Severe'   => 'orange',
    'Moderate' => 'yellow',
    'Minor'    => 'green',
);

my $background = $bkcolor{$severity} // 'grey';

Thank you very much for you time and help!

It is worth noting that the // operator is new perl 5.10.0, so if yo uuse it, you should start your code with

use 5.010;

Then if somebody accidentally runs the code with an older version of perl, you get a much better error message.
