NAME

Defined::KV - Create a KV pair, but only if the value is defined

SYNOPSIS

use Defined::KV;
use Test::More;

my $foo;
my $bar = 1;
my $baz = 0;

my %dict = (
  defined_kv(foo => $foo),
  defined_kv(bar => $bar),
  defined_kv(baz => $baz),
);

is_deeply(\%dict, { bar => 1, baz => 0 });

DESCRIPTION

Defined::KV exports a single function, defined_kv. Call it with two arguments. If the second argument is defined, both are returned, otherwise nothing is returned.

This exists to replace this construct:

(defined $v ? ($k => $v) : ())

with something less awkward and repetetive, namely:

defined_kv($k => $v)
