NAME
    Acme::CPANModules::DumpingDataForDebugging - List of modules and tips
    when dumping data structures for debugging

VERSION
    This document describes version 0.002 of
    Acme::CPANModules::DumpingDataForDebugging (from Perl distribution
    Acme-CPANModules-DumpingDataForDebugging), released on 2023-10-29.

DESCRIPTION
    This list catalogs some of the modules you can you to dump your data
    structures for debugging purposes, so the modules will be judged mostly
    by the appropriateness of its output for human viewing (instead of other
    criteria like speed, footprint, etc).

ACME::CPANMODULES ENTRIES
    Data::Dumper
        Author: NWCLARK <https://metacpan.org/author/NWCLARK>

        Everybody knows this module and it's core so sometimes it's the only
        appropriate choice. However, the default setting is not really
        optimized for viewing by human. I suggest you tweak these before
        dumping your data:

        *   Set $Data::Dumper::Useqq to 1.

        By default, Data::Dumper quotes strings using single-quotes and does
        not quote things like "\n" and "\b" making it difficult to spot
        special characters.

    Data::Dump
        Author: GARU <https://metacpan.org/author/GARU>

        A data dumper that produces nicer Perl code output, with features
        like vertical alignment of "=>" when dumping hashes, compacting
        sequences like 1,2,3,4,5,6 to 1..6, compacting repeating characters
        in string like "ccccccccccccccccccccc" to ("c" x 21), and so on.

        It tries harder to produce Perl code that generates the original
        data structure, particularly with circular references. But with
        interlinked references like trees, Data::Dumper might be more
        helpful in showing you which references get mentioned where. For
        example this data:

         $tree = {children=>[{children=>[{}]}, {children=>[]}]};
         $tree->{children}[0]{parent}=$tree;
         $tree->{children}[1]{parent}=$tree;
         $tree->{children}[0]{children}[0]{parent} = $tree->{children}[0];

        Data::Dump will produce:

         do {
            my $a = {
              children => [
               { children => [{ parent => 'fix' }], parent => 'fix' },
               { children => [], parent => 'fix' },
             ],
           };
           $a->{children}[0]{children}[0]{parent} = $a->{children}[0];
           $a->{children}[0]{parent} = $a;
           $a->{children}[1]{parent} = $a;
           $a;
         }

        while Data::Dumper will produce:

         $VAR1 = {
                   'children' => [
                                   {
                                     'children' => [
                                                     {
                                                       'parent' => $VAR1->{'children'}[0]
                                                     }
                                                   ],
                                     'parent' => $VAR1
                                   },
                                   {
                                     'parent' => $VAR1,
                                     'children' => []
                                   }
                                 ]
                 };

    Data::Dump::Color
        Author: PERLANCAR <https://metacpan.org/author/PERLANCAR>

        A modification to Data::Dump which adds color (and color theme)
        support, as well as other visual aids like depth and array
        index/hash pair count indicator. It's usually my go-to module for
        debugging.

    Alternatively you can use the cpanmodules CLI (from App::cpanmodules
    distribution):

        % cpanmodules ls-entries DumpingDataForDebugging | cpanm -n

    or Acme::CM::Get:

        % perl -MAcme::CM::Get=DumpingDataForDebugging -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

    or directly:

        % perl -MAcme::CPANModules::DumpingDataForDebugging -E'say $_->{module} for @{ $Acme::CPANModules::DumpingDataForDebugging::LIST->{entries} }' | cpanm -n

    This Acme::CPANModules module also helps lcpan produce a more meaningful
    result for "lcpan related-mods" command when it comes to finding related
    modules for the modules listed in this Acme::CPANModules module. See
    App::lcpan::Cmd::related_mods for more details on how "related modules"
    are found.

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR,
    Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
    required beyond that are considered a bug and can be reported to me.
