Hash::Digger - Access nested hash structures without vivification
Version 0.0.5
Allows accessing hash structures without triggering autovivification.
my %hash;
$hash{'foo'}{'bar'} = 'baz';
diggable \%hash, 'foo', 'bar';
# Truthy
diggable \%hash, 'xxx', 'yyy';
# Falsey
dig \%hash, 'foo', 'bar';
# 'baz'
dig \%hash, 'foo', 'bar', 'xxx';
# undef
exhume 'some default', \%hash, 'foo', 'bar';
# 'baz'
exhume 'some default', \%hash, 'foo', 'xxx';
# 'some default'
# Hash structure has not changed:
use Data::Dumper;
Dumper \%hash;
# $VAR1 = {
# 'foo' => {
# 'bar' => 'baz'
# }
# };
dig, diggable, exhume
Check if given path is diggable on the hash (`exists` equivalent)
Dig the hash and return the value. If the path is not valid, it returns undef.
Dig the hash and return the value. If the path is not valid, it returns a default value.
