NAME

Perinci::Access::Perl - Access Perl module, functions, variables through Riap

VERSION

version 0.50

SYNOPSIS

First write your code and add Rinci metadata to them:

package MyMod::MySubMod;

our %SPEC;

$SPEC{':package'} = {
    v => 1.1,
    summary => 'This package is blah blah',
};

$SPEC{'$var1'} = {
    v => 1.1,
    summary => 'This variable is blah blah',
};
our $var1;

$SPEC{func1} = {
    v => 1.1,
    summary => 'This function does blah blah',
    args => {
        a => { schema => 'int', req => 1 },
        b => { schema => 'int' },
    },
};
sub func1 {
    ...
}
1;

then access them through Riap:

use Perinci::Access::Perl;
my $pa = Perinci::Access::Perl->new;

# call function
$res = $pa->request(call => '/MyMod/MySubMod/func1', {args=>{a=>1, b=>2}});

# get variables
$res = $pa->request(get => '/MyMod/MySubMod/$var1');

DESCRIPTION

This class allows you to access Perl modules, functions, and variables through Riap. Only those which have Rinci metadata are accessible. The metadata is put in %SPEC package variables, with function names as keys, or :package for package metadata, or $NAME for variables. Functions will be wrapped before executed (unless you pass wrap => 0 to the constructor).

You should probably use this through Perinci::Access.

FUNCTIONS

new(%opts) => OBJ

Constructor. For a list of options, see superclass Perinci::Access::Schemeless except for package_prefix which are not recognized by this class.

$pa->request($action, $uri, \%extras) => RESP

$pa->parse_url($url) => HASH

FAQ

Why %SPEC (instead of %META, %METADATA, %RINCI, etc)?

The name was first chosen during Sub::Spec era (see BackPAN) in 2011, it stuck. By that time I already had had a lot of code written using %SPEC.

Why wrap?

The wrapping process accomplishes several things, among others: checking of metadata, normalization of schemas in metadata, also argument validation and exception trapping in function.

The function wrapping introduces a small overhead when performing a sub call (typically around several to tens of microseconds on an Intel Core i5 1.7GHz notebook). This is usually smaller than the overhead of Perinci::Access::Perl itself (typically in the range of 100 microseconds). But if you are concerned about the wrapping overhead, see the wrap => 0 option.
