NAME

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

VERSION

This document describes version 1.726 of Perinci::CmdLine::Util::Config (from Perl distribution Perinci-CmdLine-Util-Config), released on 2022-05-02.

FUNCTIONS

get_args_from_config

Usage:

get_args_from_config(%args) -> [$status_code, $reason, $payload, \%result_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 ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

get_default_config_dirs

Usage:

get_default_config_dirs() -> [$status_code, $reason, $payload, \%result_meta]

This function is not exported by default, but exportable.

No arguments.

Returns an enveloped result (an array).

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
