libdata-compare-perl

Compare two perl data structures recursively. Returns 0 if the structures differ, else returns 1. A few data types are treated as special cases: * Scalar::Properties objects This has been moved into a plugin, although functionality remains the same as with the previous version. Full documentation is in Data::Compare::Plugins::Scalar::Properties. * Compiled regular expressions, eg qr/foo/ These are stringified before comparison, so the following will match: $r = qr/abc/i; $s = qr/abc/i; Compare($r, $s); and the following won't, despite them matching *exactly* the same text: $r = qr/abc/i; $s = qr/[aA][bB][cC]/; Compare($r, $s); Sorry, that's the best we can do. * CODE and GLOB references These are assumed not to match unless the references are identical - ie, both are references to the same thing. You may also customise how we compare structures by supplying options in a hashref as a third parameter to the 'Compare()' function. This is not yet available through the OO-ish interface. These options will be in force for the *whole* of your comparison, so will apply to structures that are lurking deep down in your data as well as at the top level, so beware! * ignore_hash_keys an arrayref of strings. When comparing two hashes, any keys mentioned in this list will be ignored.
