NAME

       JSON::Syck - JSON is YAML (but consider using JSON::XS instead!)

SYNOPSIS

           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);

DESCRIPTION

       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 :-)

REFERENCES

   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.

UTF-8 FLAGS

       By default this module doesn't touch any of utf-8 flags set in strings, and assumes UTF-8
       bytes to be passed and emit.

       However, when you set $JSON::Syck::ImplicitUnicode to 1, this module properly decodes
       UTF-8 binaries and sets UTF-8 flag everywhere, as in:

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

       By default, JSON::Syck::Dump will only transverse up to 512 levels of a datastructure in
       order to avoid an infinite loop when it is presented with an circular reference.

       However, you set $JSON::Syck::MaxLevels to a larger value if you have very complex
       structures.

       Unfortunately, there's no implicit way to dump Perl UTF-8 flagged data structure to utf-8
       encoded JSON. To do this, simply use Encode module, e.g.:

         use Encode;
         use JSON::Syck qw(Dump);

         my $json = encode_utf8( Dump($data) );

       Alternatively you can use Encode::JavaScript::UCS to encode Unicode strings as in %uXXXX
       form.

         use Encode;
         use Encode::JavaScript::UCS;
         use JSON::Syck qw(Dump);

         my $json_unicode_escaped = encode( 'JavaScript-UCS', Dump($data) );

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.

BUGS

       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.
