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.
