Perinci::Sub::ConvertArgs::Array - Convert hash arguments to array

VERSION

This document describes version 0.08 of Perinci::Sub::ConvertArgs::Array (from Perl distribution Perinci-Sub-ConvertArgs-Array), released on 2015-12-29.

SYNOPSIS

 use Perinci::Sub::ConvertArgs::Array qw(convert_args_to_array);

 my $res = convert_args_to_array(args=>\%args, meta=>$meta, ...);

DESCRIPTION

This module provides convert_args_to_array() (and gencode_convert_args_to_array(), upcoming). This module is used by, among others, Perinci::Sub::Wrapper.

FUNCTIONS

convert_args_to_array(%args) -> [status, msg, result, meta]

Convert hash arguments to array.

Using information in 'args' property (particularly the 'pos' and 'greedy' of each argument spec), convert hash arguments to array.

Example:

 my $meta = {
     v => 1.1,
     summary => 'Multiply 2 numbers (a & b)',
     args => {
         a => ['num*' => {arg_pos=>0}],
         b => ['num*' => {arg_pos=>1}],
     }
 }

then 'convert_args_to_array(args=>{a=>2, b=>3}, meta=>$meta)' will produce:

 [200, "OK", [2, 3]]

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• args* => hash

• meta* => hash

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
