       Rinci::Upgrading - Upgrading from previous version of specification


       This document describes version 1.1.93 of Rinci::Upgrading (from Perl distribution Rinci),
       released on 2019-07-19.


       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 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

       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

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

       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

       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.
