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 or JSON::Syck.

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.

METHODS

my $json_str = to_json($data)

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

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.
