NAME

       YAML::PP::Schema::JSON - YAML 1.2 JSON Schema

SYNOPSIS

           my $yp = YAML::PP->new( schema => ['JSON'] );
           my $yp = YAML::PP->new( schema => [qw/ JSON empty=str /] );
           my $yp = YAML::PP->new( schema => [qw/ JSON empty=null /] );

DESCRIPTION

       With this schema, the resolution of plain values will work like in JSON.  Everything that
       matches a special value will be loaded as such, other plain scalars will be loaded as
       strings.

       Note that this is different from the official YAML 1.2 JSON Schema, where all strings have
       to be quoted.

       Here you can see all Schemas and examples implemented by YAML::PP:
       <https://perlpunk.github.io/YAML-PP-p5/schemas.html>

       Official Schema: <https://yaml.org/spec/1.2/spec.html#id2803231>

CONFIGURATION

       The official YAML 1.2 JSON Schema wants all strings to be quoted.  YAML::PP currently does
       not require that (it might do this optionally in the future).

       That means, there are no empty nodes allowed in the official schema. Example:

           ---
           key:

       The default behaviour of YAML::PP::Schema::JSON is to return an empty string, so it would
       be equivalent to:

           ---
           key: ''

       You can configure it to resolve this as "undef":

           my $yp = YAML::PP->new( schema => [qw/ JSON empty=null /] );

       This way it is equivalent to:

           ---
           key: null

       The default is:

           my $yp = YAML::PP->new( schema => [qw/ JSON empty=str /] );
