NAME

Rinci::Upgrading - Upgrading from previous version of specification

VERSION

This document describes version 1.1.84 of Rinci::Upgrading (from Perl distribution Rinci), released on 2016-12-28.

DESCRIPTION

This document gives guide on how to convert your metadata from older version.

Examples are written in Perl, but are not limited to this language.

UPGRADING FROM SUB::SPEC 1.0 TO RINCI 1.1

Upgrading function metadata

In Perl, you can use Perinci::Sub::Wrapper (which in turn is used by Perinci::Access) to automatically convert Sub::Spec 1.0 metadata to 1.1, so you can skip this document if you want.

Terminology change: (sub) spec is now called metadata: the reason is because there are now metadata for functions as well as other code entities like variables, packages, etc. clause is now called property: the reason is to avoid confusion with Data::Sah's clause.

The v (spec version) property is required, add

 v => 1.1

to your function metadata.

Each argument in the args property is now a hash, instead of a schema. Move the schema to the schema key of the hash. To specify required argument, add req set to 1 to hash key. Move arg_pos Sah clause to pos hash key. Move arg_greedy Sah clause to greedy hash key. Move arg_completion Sah clause to completion hash key.

Example, change this:

 args => {
     # a required argument
     arg1 => ['int*', {
         summary => 'Blah ...',
         min => 1, max => 100,
         arg_pos => 0,
     }],

     # an optional argument
     arg2 => ['bool', {
         summary => 'Blah ...',
         default => 0,
     }],
 }

Into this:

 args => {
     arg1 => {
         summary => 'Blah ...',
         schema => ['int*', {min=>1, max=>100}],
         req => 1,
         pos => 0,
     },

     arg2 => {
         summary => 'Blah ...',
         schema => [bool => {default=>0}],
     },
 }

It is now possible to give summary and description to the schema as well as to the argument.

Accordingly, the result property is also now a hash, instead of schema. Move the schema into the schema hash key.

Sub::Spec::HTTP

For the most part, you only need to upgrade client and server library. Client library is now Perinci::CmdLine and Perinci::Access. Server library is now Perinci::Access::HTTP::Server.

Specification is now Riap and Riap::HTTP. Terminology changes. SS request now becomes Riap request. Some key names changed (shortened). Special headers are now prefixed with X-Riap-* instead of X-SS-Req-*.

Log levels are now numeric only (1-6) instead of numeric/string.
