NAME
    App::AdditivesUtils - Utilities related to food additives
VERSION
    This document describes version 0.004 of App::AdditivesUtils (from Perl
    distribution App-AdditivesUtils), released on 2023-02-05.
DESCRIPTION
    This distributions provides the following command-line utilities:
    *   convert-benzoate-unit
FUNCTIONS
  convert_benzoate_unit
    Usage:
     convert_benzoate_unit(%args) -> [$status_code, $reason, $payload, \%result_meta]
    Convert a benzoate quantity from one unit to another.
    Examples:
    *   Show all possible conversions:
         convert_benzoate_unit(quantity => "ppm");
        Result:
         [
           200,
           "OK",
           [
             { amount => 1, unit => "ppm" },
             { amount => 0.847408229824443, unit => "ppm-as-benzoic-acid" },
             { amount => 1, unit => "ppm-as-sodium-benzoate" },
             { amount => 1, unit => "ppm-as-na-benzoate" },
             { amount => 1.11172021372563, unit => "ppm-as-potassium-benzoate" },
             { amount => 1.04239816806606, unit => "ppm-as-k-benzoate" },
             { amount => 0.979494830337937, unit => "ppm-as-calcium-benzoate" },
             { amount => 0.979494830337937, unit => "ppm-as-ca-benzoate" },
           ],
           {},
         ]
    *   Convert from ppm (as sodium benzoate) to ppm (as benzoic acid):
         convert_benzoate_unit(quantity => "250 ppm", to_unit => "ppm-as-benzoic-acid");
        Result:
         [200, "OK", 211.852057456111, {}]
    If target unit is not specified, will show all known conversions.
    This function is not exported.
    Arguments ('*' denotes required arguments):
    *   quantity* => *str*
        (No description)
    *   to_unit => *str*
        (No description)
    Returns an enveloped result (an array).
    First element ($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)

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,
    Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
    required beyond that are considered a bug and can be reported to me.
