NAME
    Perinci::Object - Object-oriented interface for Rinci metadata

VERSION
    This document describes version 0.311 of Perinci::Object (from Perl
    distribution Perinci-Object), released on 2020-01-02.

SYNOPSIS
     use Perinci::Object; # automatically exports risub(), rivar(), ripkg(),
                          # envres(), envresmulti(), envrestable(), riresmeta()
     use Data::Dump; # for dd()

     # OO interface to function metadata.

     my $risub = risub {
         v => 1.1,
         summary => 'Calculate foo and bar',
         "summary.alt.lang.id_ID" => 'Menghitung foo dan bar',
         args => { a1 => { schema => 'int*' }, a2 => { schema => 'str' } },
         features => { pure=>1 },
     };
     dd $risub->type,                                 # "function"
        $risub->v,                                    # 1.1
        $risub->arg('a1'),                            # { schema=>'int*' }
        $risub->arg('a3'),                            # undef
        $risub->feature('pure'),                      # 1
        $risub->feature('foo'),                       # undef
        $risub->langprop('summary'),                  # 'Calculate foo and bar'
        $risub->langprop({lang=>'id_ID'}, 'summary'), # 'Menghitung foo dan bar'

     # setting arg and property
     $risub->arg('a3', 'array');  # will actually fail for 1.0 metadata
     $risub->feature('foo', 2);   # ditto

     # OO interface to variable metadata

     my $rivar = rivar { ... };

     # OO interface to package metadata

     my $ripkg = ripkg { ... };

     # OO interface to enveloped result

     my $envres = envres [200, "OK", [1, 2, 3]];
     dd $envres->is_success, # 1
        $envres->status,     # 200
        $envres->message,    # "OK"
        $envres->result,     # [1, 2, 3]
        $envres->meta;       # undef

     # setting status, message, result, extra
     $envres->status(404);
     $envres->message('Not found');
     $envres->result(undef);
     $envres->meta({errno=>-100});

     # OO interface to function/method result metadata
     my $riresmeta = riresmeta { ... };

     # an example of using envresmulti()
     sub myfunc {
         ...

         my $envres = envresmulti();

         # add result for each item
         $envres->add_result(200, "OK", {item_id=>1, payload=>"a"});
         $envres->add_result(202, "OK", {item_id=>2, note=>"blah", payload=>"b"});
         $envres->add_result(404, "Not found", {item_id=>3});
         ...

         # finally, return the result
         return $envres->as_struct;
     }

     # an example of using envrestable()
     sub myfunc {
         ...
         my $envres = envrestable();
         $envres->add_field('foo');
         $envres->add_field('bar');
         ...
         return $envres->as_struct;
     }

DESCRIPTION
    Rinci works using pure data structures, but sometimes it's convenient to
    have an object-oriented interface (wrapper) for those data. This module
    provides just that.
