NAME

       Rinci::Upgrading - Upgrading from previous version of specification

VERSION

       This document describes version 1.1.78 of Rinci::Upgrading (from Perl distribution Rinci),
       released on 2015-09-03.

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.
