Perinci::Sub::ConvertArgs::Argv - Convert hash arguments to command-line options (and arguments)
This document describes version 0.110 of Perinci::Sub::ConvertArgs::Argv (from Perl distribution Perinci-Sub-ConvertArgs-Argv), released on 2019-04-15.
use Perinci::Sub::ConvertArgs::Argv qw(convert_args_to_argv); my $res = convert_args_to_argv(args=>\%args, meta=>$meta, ...);
Usage:
convert_args_to_argv(%args) -> [status, msg, payload, meta]
Convert hash arguments to command-line options (and arguments).
Convert hash arguments to command-line arguments. This is the reverse of Perinci::Sub::GetArgs::Argv::get_args_from_argv.
Perinci::Sub::GetArgs::Argv::get_args_from_argv
Note: currently the function expects schemas in metadata to be normalized already.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
args* => hash
meta => hash
use_pos => bool
Whether to use positional arguments.
For example, given this metadata:
{ v => 1.1, args => { arg1 => {pos=>0, req=>1}, arg2 => {pos=>1}, arg3 => {}, }, }
then under use_pos=0 the hash {arg1=>1, arg2=>2, arg3=>'a b'} will be converted to ['--arg1', 1, '--arg2', 2, '--arg3', 'a b']. Meanwhile if use_pos=1 the same hash will be converted to [1, 2, '--arg3', 'a b'].
use_pos=0
{arg1=>1, arg2=>2, arg3=>'a b'}
['--arg1', 1, '--arg2', 2, '--arg3', 'a b']
use_pos=1
[1, 2, '--arg3', 'a b']
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 (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
Return value: (any)
