NAME
    Data::Dump::HTML::PopUp - Dump Perl data structures as HTML document
    with nested pop ups

VERSION
    This document describes version 0.001 of Data::Dump::HTML::PopUp (from
    Perl distribution Data-Dump-HTML-PopUp), released on 2024-03-17.

SYNOPSIS
     use Data::Dump::HTML::PopUp; # exports dd(), can export dump()
     dd [1, 2, 3];

DESCRIPTION
    This module is a Data::Dump variant that dumps Perl data structure to
    HTML document where you can expand and collapse nodes to drill down and
    roll up your data. The nodes will expand in (nested) pop up modal
    dialogs. It currently uses jQuery [1] and Modally [2] JavaScript
    libraries.

    There are other collapsible HTML dumper modules on CPAN (see "SEE
    ALSO").

VARIABLES
  $Data::Dump::HTML::PopUp::OPT_PERL_VERSION
    String, default: 5.010.

    Set target Perl version. If you set this to, say 5.010, then the dumped
    code will keep compatibility with Perl 5.10.0. This is used in the
    following ways:

    *   passed to Regexp::Stringify

    *   when dumping code references

        For example, in perls earlier than 5.016, feature.pm does not
        understand:

         no feature ':all';

        so we replace it with:

         no feature;

  $Data::Dump::HTML::PopUp::OPT_REMOVE_PRAGMAS
    Bool, default: 0.

    If set to 1, then pragmas at the start of coderef dump will be removed.
    Coderef dump is produced by B::Deparse and is of the form like:

     sub { use feature 'current_sub', 'evalbytes', 'fc', 'say', 'state', 'switch', 'unicode_strings', 'unicode_eval'; $a <=> $b }

    If you want to dump short coderefs, the pragmas might be distracting.
    You can turn turn on this option which will make the above dump become:

     sub { $a <=> $b }

    Note that without the pragmas, the dump might be incorrect.

  $Data::Dump::HTML::PopUp::::OPT_DEPARSE
    Bool, default: 1.

    Can be set to 0 to skip deparsing code. Coderefs will be dumped as
    "sub{"DUMMY"}" instead, like in Data::Dump.

  $Data::Dump::HTML::PopUp::::OPT_STRINGIFY_NUMBERS
    Bool, default: 0.

    If set to true, will dump numbers as quoted string, e.g. 123 as "123"
    instead of 123. This might be helpful if you want to compute the hash of
    or get a canonical representation of data structure.

  $Data::Dump::HTML::PopUp::::OPT_LIBRARY_LINK_MODE
    Str, default: "local". Valid values: "none", "embed", "local", "cdn".

    Specify how the JavaScript libraries should be linked in the generated
    HTML page. The JavaScript libraries are linked at the preamble which is
    generated before the actual dump:

     <link rel="stylesheet" href="jquery.modally.css">
     <script src="jquery.min.js"></script>
     <script src="jquery.modally.js"></script>

    If the setting is set to "none", then no preamble will be produced at
    all. If the setting is set to "embed", then instead of being linked, the
    source code of the JavaScript libraries will be directly embedded. If
    the setting is set to "local", then the links will be to the local
    filesystem to the library files included in the distribution's shared
    directory. If the setting is set to "cdn", then the links will be to the
    CDN URLs.

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.
