( #3333=superdoc: print w/replies, xml ) Need Help??
A while ago I started on a data dumper that wasn't designed to be eval-able (like Data::Dumper) but human-readable and - more importantly - accurate.

I've just more-or-less finished the first version which fairly decently meets these goals, by doing a breadth-first walk and making use of B to analyze the data.

An example of what Data::XDumper does:

use Data::XDumper qw(Dump); sub Test { unshift @_, { y => \@_ }; \@_ } my $x = "foo"; my $data = Test($x, substr($x, 1, 2)); bless $data, 'Quux'; bless \$data, 'Bar'; Dump $data, $data;
with default settings produces the output:
$L001:  Bar \
@L003:     Quux @(
              {y => \@L003},
$L002:        'foo',
              substr($L002, 1, 2)
           )
        $L001
Here are direct links to the sources: Data::XDumper 1.03 and its prerequisite B::More 1.01. You can also browse them at CPAN.

•Update: found a major memory leak, fixed Feb 20 13:11:50 CET 2003 in 1.03

And a syntax-highlighted version for online reading (also updated)

I hope I can get some feedback on my approach and layout, and I need to know how robust it is. I've tried all kinds of input but the possibilities are endless, so perhaps other people can find things it breaks on.

•Update: what I mean with the above paragraph is: Could you please run the most disgusting piece of data you can think of through XDumper and report the results? :-)

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 How to display code and escape characters are good places to start.
