JSON::Syck - JSON is YAML (but consider using JSON::XS instead!)
use JSON::Syck; # no exports by default my $data = JSON::Syck::Load($json); my $json = JSON::Syck::Dump($data); # $file can be an IO object, or a filename my $data = JSON::Syck::LoadFile($file); JSON::Syck::DumpFile($file, $data); # Dump into a pre-existing buffer my $json; JSON::Syck::DumpInto(\$json, $data);
JSON::Syck is a syck implementation of JSON parsing and generation. Because JSON is YAML (<http://redhanded.hobix.com/inspect/yamlIsJson.html>), using syck gives you a fast and memory-efficient parser and dumper for JSON data representation. However, a newer module JSON::XS, has since emerged. It is more flexible, efficient and robust, so please consider using it instead of this module.
DIFFERENCE WITH JSON
You might want to know the difference between the JSON module and this one. 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 :-)
SCALAR REFERENCE For now, when you pass a scalar reference to JSON::Syck, it dereferences to get the actual scalar value. JSON::Syck raises an exception when you pass in circular references. If you want to serialize self referencing stuff, you should use YAML which supports it. SUBROUTINE REFERENCE When you pass subroutine reference, JSON::Syck dumps it as null.
Dumping into tied (or other magic variables) with "DumpInto" might not work properly in all cases. When dumping with "DumpFile", some spacing might be wrong and $JSON::Syck::SingleQuote might be handled incorrectly.
