SYNOPSIS

9           use Hash::Diff qw( diff );
10           my %a = (
11                       'foo'    => 1,
12                   'bar'    => { a => 1, b => 1 },
13               );
14           my %b = (
15                       'foo'     => 2,
16                       'bar'    => { a => 1 },
17               );
18
19           my %c = %{ diff( \%a, \%b ) };
20
21           # %c = %{ foo => 1, bar => { b => 1} }

DESCRIPTION

24       Hash::Diff returns the difference between two hashes as a hash.
25
26       diff ( <hashref>, <hashref> )
27           Diffs two hashes.  Returns a reference to the new hash.
28
29       left_diff ( <hashref>, <hashref> )
30           Returns the values in the left hash that is not, or different from
31           the right hash.
32

CAVEATS

34       This will not handle self-referencing/recursion within hashes well.
35       This will only handle HASH and SCALAR.
36
37       Plans for a future version include incorporate deep recursion
38       protection.  And support for ARRAY.
