( #3333=superdoc: print w/replies, xml ) Need Help??
Update: What I didn't specify, but perhaps should have, is that parts of the data structure are blessed object references, and I want to compare the guts of the objects.

Conclusion:

ModuleConclusion
Data::DumperHashes not consistently serialised
Test::MoreOnly does a shallow comparison.
Tie::IxHashSolves a different problem. Anonymous hashes cannot be tied
FreezeThawOnly copes with shallow structures
Struct::CompareDoes not handle references
Recursive comparison by thraxilDoes not handle object references
Data::CompareDoes not handle references

Conclusion: either fix Data::Dumper or roll my own compare routine :-<.

Update 2: I have been looking further at Test::More. There are numerous versions floating about, owing to the way in which people have used it to package up their tests in their own modules.

The definitive Test::More on CPAN has a function eq_hash, which suffers from the same syndrome as Data::Dumper when it comes to ordering of keys.

Update 3: simonm++ The module Class::MakeMethods::Utility::Ref does the business! Shame about the name - something as useful should not IMO have a module name 4 levels down, with no clue as to what it can do.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
