.SH &quot;DESCRIPTION&quot;
.IX Header &quot;DESCRIPTION&quot;
\&amp;\fBParse::CPAN::Meta\fR is a parser for \fI\s-1META\s0.json\fR and \fI\s-1META\s0.yml\fR files, using
\&amp;\s-1JSON::PP\s0 and/or CPAN::Meta::YAML.
.PP
\&amp;\fBParse::CPAN::Meta\fR provides three methods: \f(CW\*(C`load_file\*(C'\fR, \f(CW\*(C`load_json_string\*(C'\fR,
and \f(CW\*(C`load_yaml_string\*(C'\fR.  These will read and deserialize \s-1CPAN\s0 metafiles, and
are described below in detail.
.PP
\&amp;\fBParse::CPAN::Meta\fR provides a legacy \s-1API\s0 of only two functions,
based on the \s-1YAML\s0 functions of the same name. Wherever possible,
identical calling semantics are used.  These may only be used with \s-1YAML\s0 sources.
.PP
All error reporting is done with exceptions (die'ing).
.PP
Note that \s-1META\s0 files are expected to be in \s-1UTF\-8\s0 encoding, only.  When
converted string data, it must first be decoded from \s-1UTF\-8.\s0
.SH &quot;METHODS&quot;
.IX Header &quot;METHODS&quot;
.SS &quot;load_file&quot;
.IX Subsection &quot;load_file&quot;
.Vb 1
\&amp;  my $metadata_structure = Parse::CPAN::Meta\-&gt;load_file(\*(AqMETA.json\*(Aq);
\&amp;
\&amp;  my $metadata_structure = Parse::CPAN::Meta\-&gt;load_file(\*(AqMETA.yml\*(Aq);
.Ve
.PP
This method will read the named file and deserialize it to a data structure,
determining whether it should be \s-1JSON\s0 or \s-1YAML\s0 based on the filename.
The file will be read using the \*(L&quot;:utf8\*(R&quot; \s-1IO\s0 layer.
.SS &quot;load_yaml_string&quot;
.IX Subsection &quot;load_yaml_string&quot;
.Vb 1
\&amp;  my $metadata_structure = Parse::CPAN::Meta\-&gt;load_yaml_string($yaml_string);
.Ve
.PP
This method deserializes the given string of \s-1YAML\s0 and returns the first
document in it.  (\s-1CPAN\s0 metadata files should always have only one document.)
If the source was \s-1UTF\-8\s0 encoded, the string must be decoded before calling
\&amp;\f(CW\*(C`load_yaml_string\*(C'\fR.
.SS &quot;load_json_string&quot;
.IX Subsection &quot;load_json_string&quot;
.Vb 1
\&amp;  my $metadata_structure = Parse::CPAN::Meta\-&gt;load_json_string($json_string);
.Ve
.PP
This method deserializes the given string of \s-1JSON\s0 and the result.  
If the source was \s-1UTF\-8\s0 encoded, the string must be decoded before calling
\&amp;\f(CW\*(C`load_json_string\*(C'\fR.
.SS &quot;load_string&quot;
.IX Subsection &quot;load_string&quot;
.Vb 1
\&amp;  my $metadata_structure = Parse::CPAN::Meta\-&gt;load_string($some_string);
.Ve
.PP
If you don't know whether a string contains \s-1YAML\s0 or \s-1JSON\s0 data, this method
will use some heuristics and guess.  If it can't tell, it assumes \s-1YAML.\s0
.SS &quot;yaml_backend&quot;
.IX Subsection &quot;yaml_backend&quot;
.Vb 1
\&amp;  my $backend = Parse::CPAN::Meta\-&gt;yaml_backend;
.Ve
.PP
Returns the module name of the \s-1YAML\s0 serializer. See \*(L&quot;\s-1ENVIRONMENT\*(R&quot;\s0
for details.
.SS &quot;json_backend&quot;
.IX Subsection &quot;json_backend&quot;
.Vb 1
\&amp;  my $backend = Parse::CPAN::Meta\-&gt;json_backend;
.Ve
.PP
Returns the module name of the \s-1JSON\s0 serializer.  This will either
be \s-1JSON::PP\s0 or \s-1JSON\s0.  Even if \f(CW\*(C`PERL_JSON_BACKEND\*(C'\fR is set,
this will return \s-1JSON\s0 as further delegation is handled by
the \s-1JSON\s0 module.  See \*(L&quot;\s-1ENVIRONMENT\*(R&quot;\s0 for details.
.SH &quot;FUNCTIONS&quot;
.IX Header &quot;FUNCTIONS&quot;
For maintenance clarity, no functions are exported by default.  These functions
are available for backwards compatibility only and are best avoided in favor of
\&amp;\f(CW\*(C`load_file\*(C'\fR.
.SS &quot;Load&quot;
.IX Subsection &quot;Load&quot;
.Vb 1
\&amp;  my @yaml = Parse::CPAN::Meta::Load( $string );
.Ve
.PP
Parses a string containing a valid \s-1YAML\s0 stream into a list of Perl data
structures.
.SS &quot;LoadFile&quot;
.IX Subsection &quot;LoadFile&quot;
.Vb 1
\&amp;  my @yaml = Parse::CPAN::Meta::LoadFile( \*(AqMETA.yml\*(Aq );
.Ve
.PP
Reads the \s-1YAML\s0 stream from a file instead of a string.
.SH &quot;ENVIRONMENT&quot;
.IX Header &quot;ENVIRONMENT&quot;
.SS &quot;\s-1PERL_JSON_BACKEND\s0&quot;
.IX Subsection &quot;PERL_JSON_BACKEND&quot;
By default, \s-1JSON::PP\s0 will be used for deserializing \s-1JSON\s0 data. If the
\&amp;\f(CW\*(C`PERL_JSON_BACKEND\*(C'\fR environment variable exists, is true and is not
\&amp;\*(L&quot;\s-1JSON::PP\*(R&quot;,\s0 then the \s-1JSON\s0 module (version 2.5 or greater) will be loaded and
used to interpret \f(CW\*(C`PERL_JSON_BACKEND\*(C'\fR.  If \s-1JSON\s0 is not installed or is too
old, an exception will be thrown.
.SS &quot;\s-1PERL_YAML_BACKEND\s0&quot;
.IX Subsection &quot;PERL_YAML_BACKEND&quot;
By default, CPAN::Meta::YAML will be used for deserializing \s-1YAML\s0 data. If
the \f(CW\*(C`PERL_YAML_BACKEND\*(C'\fR environment variable is defined, then it is interpreted
as a module to use for deserialization.  The given module must be installed,
must load correctly and must implement the \f(CW\*(C`Load()\*(C'\fR function or an exception
will be thrown.
