Sah::PSchema - Retrieve and resolve parameterized Sah schema

VERSION

This document describes version 0.002 of Sah::PSchema (from Perl distribution Sah-PSchema), released on 2020-06-06.

SYNOPSIS

In YourModule.pm:

 package YourModule;
 use Sah::PSchema 'get_schema';

 our %SPEC;
 $SPEC{pick_word_from_wordlist} = {
     v => 1.1,
     args => {
         wordlist => {
             schema => get_schema('perl::modname', {ns_prefix=>'WordList'}, {req=>1}),
             req => 1,
             pos => 0,
         },
     }
 };
 sub pick_word_from_wordlist {
     ...
 }

 1;

DESCRIPTION

EXPERIMENTAL.

This module implements parameterized Sah schema in a simple way.

FUNCTIONS

get_schema

Usage:

 my $sch = get_schema($psch, \%args [ , \%clause_set ]);

Example:

 my $sch = get_schema("perl::modname", {ns_prefix=>"WordList"}, {req=>1});
 # => ["perl::modname", {req=>1, 'x.completion'=>[perl_modname => {ns_prefix=>"WordList"}]}]

The function simply loads Sah::PSchema::$psch module then calls its get_schema method with the arguments \%args and \%clause_set. In the above example, the module Sah::PSchema::perl::modname module is loaded. This parameterized schema basically just return the regular perl::modname (from Sah::Schema::perl::modname) but with the ns_prefix argument put into argument for x.completion.
