NAME
     JSON::DWIW - JSON converter that Does What I Want

SYNOPSIS
     my $json_obj = JSON::DWIW->new;
     my $data = $json_obj->from_json($json_str);
     my $str = $json_obj->to_json($data);

     my $data = JSON::DWIW->from_json($json_str);
     my $str = JSON:DWIW->to_json($data);
 
DESCRIPTION
    Other JSON modules require setting several parameters before calling the
    conversion methods to do what I want. This module does things by default
    that I think should be done when working with JSON in Perl. This module
    also encodes and decodes faster than JSON.pm and JSON::Syck in my
    benchmarks.

    This means that any piece of data in Perl will get converted to
    something in JSON instead of throwing an exception. It also means that
    output will be strict JSON, while accepted input will be flexible,
    without having to set any options.

  Encoding
    Perl objects get encoded as their underlying data structure. For
    example, a blessed hash ref will be represented as an object in JSON, a
    blessed array will be represented as an array. etc. A reference to a
    scalar is dereferenced and represented as the scalar itself. Globs,
    filehandles, etc., get stringified.

  Decoding
    When decoding, null, true, and false become undef, 1, and 0,
    repectively.

    The parser is flexible in what it accepts and handles some things not in
    the JSON spec:

    quotes
         Both single and double quotes are allowed for quoting a string, e.g.,

            [ "string1", 'string2' ]

    bare keys
         Object/hash keys can be bare if they look like an identifier, e.g.,

            { var1: "myval1", var2: "myval2" }

    extra commas
         Extra commas in objects/hashes and arrays are ignored, e.g.,

            [1,2,3,,,4,]

         becomes a 4 element array containing 1, 2, 3, and 4.

METHODS
  my $json_str = to_json($data)
     Returns the JSON representation of $data (arbitrary
     datastructure).  See http://www.json.org/ for details.

     Aliases: toJson, toJSON, objToJson

  my ($data, $error_msg) = from_json($json_str)
     Returns the Perl data structure for the given JSON string.  The
     value for true becomes 1, false becomes 0, and null gets
     converted to undef.

     Called in list context, this method returns a where the first
     element is the data and the second element is the error message,
     if any.  If $error_msg is defined, there was a problem parsing
     the JSON string, and $data will be undef.
