Hash::Diff(3) User Contributed Perl Documentation Hash::Diff(3)NAMEHash::Diff - Return difference between two hashes as a hash
SYNOPSIS
use Hash::Diff qw( diff );
my %a = (
'foo' => 1,
'bar' => { a => 1, b => 1 },
);
my %b = (
'foo' => 2,
'bar' => { a => 1 },
);
my %c = %{ diff( \%a, \%b ) };
# %c = %{ foo => 1, bar => { b => 1} }
DESCRIPTIONHash::Diff returns the difference between two hashes as a hash.
diff ( <hashref>, <hashref> )
Diffs two hashes. Returns a reference to the new hash.
left_diff ( <hashref>, <hashref> )
Returns the values in the left hash that is not, or different from
the right hash.
CAVEATS
This will not handle self-referencing/recursion within hashes well.
This will only handle HASH and SCALAR.
Plans for a future version include incorporate deep recursion
protection. And support for ARRAY.
