Because \&\s-1JSON\s0 is \s-1YAML\s0 (<http://redhanded.hobix.com/inspect/yamlIsJson.html>), using syck gives you a fast and memory-efficient parser and dumper for \s-1JSON\s0 data representation. .PP However, a newer module \s-1JSON::XS\s0, has since emerged. It is more flexible, efficient and robust, so please consider using it instead of this module. .SH "DIFFERENCE WITH JSON" .IX Header "DIFFERENCE WITH JSON" You might want to know the difference between the \fI\s-1JSON\s0\fR module and this one. .PP Since \s-1JSON\s0 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> .PP \&\s-1JSON\s0.pm comes with dozens of ways to do the same thing and lots of options, while JSON::Syck doesn't. There's only \f(CW\*(C`Load\*(C'\fR and \f(CW\*(C`Dump\*(C'\fR. .PP Oh, and JSON::Syck doesn't use camelCase method names :\-) .SH "REFERENCES" .IX Header "REFERENCES" .SS "\s-1SCALAR REFERENCE\s0" .IX Subsection "SCALAR REFERENCE" For now, when you pass a scalar reference to JSON::Syck, it dereferences to get the actual scalar value. .PP JSON::Syck raises an exception when you pass in circular references. .PP If you want to serialize self referencing stuff, you should use \&\s-1YAML\s0 which supports it. .SS "\s-1SUBROUTINE REFERENCE\s0" .IX Subsection "SUBROUTINE REFERENCE" When you pass subroutine reference, JSON::Syck dumps it as null. .SH "UTF\-8 FLAGS" .IX Header "UTF-8 FLAGS" By default this module doesn't touch any of utf\-8 flags set in strings, and assumes \s-1UTF\-8\s0 bytes to be passed and emit. .PP However, when you set \f(CW$JSON::Syck::ImplicitUnicode\fR to 1, this module properly decodes \s-1UTF\-8\s0 binaries and sets \s-1UTF\-8\s0 flag everywhere, as in: .PP .Vb 4 \& JSON (UTF\-8 bytes) => Perl (UTF\-8 flagged) \& JSON (UTF\-8 flagged) => Perl (UTF\-8 flagged) \& Perl (UTF\-8 bytes) => JSON (UTF\-8 flagged) \& Perl (UTF\-8 flagged) => JSON (UTF\-8 flagged) .Ve .PP By default, JSON::Syck::Dump will only transverse up to 512 levels of a datastructure in order to avoid an infinite loop when it is presented with an circular reference. .PP However, you set \f(CW$JSON::Syck::MaxLevels\fR to a larger value if you have very complex structures. .PP Unfortunately, there's no implicit way to dump Perl \s-1UTF\-8\s0 flagged data structure to utf\-8 encoded \s-1JSON.\s0 To do this, simply use Encode module, e.g.: .PP .Vb 2 \& use Encode; \& use JSON::Syck qw(Dump); \& \& my $json = encode_utf8( Dump($data) ); .Ve .PP Alternatively you can use Encode::JavaScript::UCS to encode Unicode strings as in \fI\f(CI%uXXXX\fI\fR form. .PP .Vb 3 \& use Encode; \& use Encode::JavaScript::UCS; \& use JSON::Syck qw(Dump); \& \& my $json_unicode_escaped = encode( \*(AqJavaScript\-UCS\*(Aq, Dump($data) ); .Ve .SH "QUOTING" .IX Header "QUOTING" According to the \s-1JSON\s0 specification, all \s-1JSON\s0 strings are to be double-quoted. However, when embedding JavaScript in \s-1HTML\s0 attributes, it may be more convenient to use single quotes. .PP Set \f(CW$JSON::Syck::SingleQuote\fR to 1 will make both \f(CW\*(C`Dump\*(C'\fR and \f(CW\*(C`Load\*(C'\fR expect single-quoted string literals. .SH "BUGS" .IX Header "BUGS" Dumping into tied (or other magic variables) with \f(CW\*(C`DumpInto\*(C'\fR might not work properly in all cases. .PP When dumping with \f(CW\*(C`DumpFile\*(C'\fR, some spacing might be wrong and \&\f(CW$JSON::Syck::SingleQuote\fR might be handled incorrectly. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\s-1JSON::XS\s0, YAML::Syck .SH "AUTHORS" .IX Header "AUTHORS" Audrey Tang <cpan@audreyt.org> .PP Tatsuhiko Miyagawa <miyagawa@gmail.com> .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2005\-2009 by Audrey Tang <cpan@audreyt.org>. .PP This software is released under the \s-1MIT\s0 license cited below. .PP The \fIlibsyck\fR code bundled with this library is released by \&\*(L"why the lucky stiff\*(R", under a BSD-style license.
