NAME

JSON::Syck - JSON is YAML

SYNOPSIS

  use JSON::Syck;

  my $data = JSON::Syck::Load($json);
  my $json = JSON::Syck::Dump($data);

DESCRIPTION

JSON::Syck is a syck implementatoin of JSON parsing and generation. Because JSON is YAML (http://redhanded.hobix.com/inspect/yamlIsJson.html), using syck gives you the fastest and most memory efficient parser and dumper for JSON data representation.

DIFFERENCE WITH JSON

You might want to know the difference between JSON and JSON::Syck.

Since JSON is a pure-perl module and JSON::Syck is based on libsyck, JSON::Syck is supposed to be very fast and memory efficient. See chansen's benchmark table at http://idisk.mac.com/christian.hansen/Public/perl/serialize.pl

JSON.pm comes with dozens of ways to do the same thing and lots of options, while JSON::Syck doesn't. There's only Load and Dump.

Oh, and JSON::Syck doesn't use camelCase method names :-)

UNICODE FLAGS

By default this module doesn't touch any of Unicode flags, and assumes UTF-8 bytes to be passed and emit as an interface. However, when you set $JSON::Syck::ImplicitUnicode to 1, this module properly decodes UTF-8 binaries and sets Unicode flag everywhere, as in:

  JSON (UTF-8 bytes)     => Perl (Unicode flagged)
  JSON (Unicode flagged) => Perl (Unicode flagged)
  Perl (UTF-8 bytes)     => JSON (Unicode flagged)
  Perl (Unicode flagged) => JSON (Unicode flagged)

QUOTING

According to the JSON specification, all JSON strings are to be double-quoted. However, when embedding JavaScript in HTML attributes, it may be more convenient to use single quotes.

Set $JSON::Syck::SingleQuote to 1 will make both Dump and Load expect single-quoted string literals.
