Hash::Diff - Return difference between two hashes as a hash
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} }
Hash::Diff returns the difference between two hashes as a hash.
Diffs two hashes. Returns a reference to the new hash.
Returns the values in the left hash that is not, or different from the right hash.
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.
Sure! Report here: http://rt.cpan.org/NoAuth/Bugs.html?Dist=Hash::Diff
