NAME
    Perinci::CmdLine::Util::Config - Utility routines related to config
    files

VERSION
    This document describes version 1.724 of Perinci::CmdLine::Util::Config
    (from Perl distribution Perinci-CmdLine-Util-Config), released on
    2020-10-21.

FUNCTIONS
  get_args_from_config
    Usage:

     get_args_from_config(%args) -> [status, msg, payload, meta]

    "config" is a HoH (hashes of hashrefs) produced by reading an INI (IOD)
    configuration file using modules like Config::IOD::Reader.

    Hashref argument "args" will be set by parameters in "config", while
    "plugins" will be set by parameters in "[plugin=...]" sections in
    "config". For example, with this configuration:

     arg1=val1
     arg2=val2
     -special_arg1=val3
     -special_arg2=val4
 
     [plugin=DumpArgs]
     -event=before_validation
 
     [plugin=Foo]
     arg1=val1

    "args" will become:

     {
       arg1=>"val1",
       arg2=>"val2",
       -special_arg1=>"val3",
       -special_arg2=>"val4",
     }

    and "plugins" will become:

     [
       'DumpArgs@before_validation' => {},
       Foo => {arg1=>val},
     ]

    This function is not exported by default, but exportable.

    Arguments ('*' denotes required arguments):

    *   args => *hash*

    *   common_opts => *any*

    *   config => *any*

    *   config_profile => *any*

    *   meta => *any*

    *   meta_is_normalized => *any*

    *   plugins => *array*

    *   r => *any*

    *   subcommand_name => *any*

    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)
