NAME
    App::QRCodeUtils - Utilities related to QR Code

VERSION
    This document describes version 0.003 of App::QRCodeUtils (from Perl
    distribution App-QRCodeUtils), released on 2024-04-17.

DESCRIPTION
    This distributions provides the following command-line utilities:

    *   decode-qrcode

    *   gen-qrcode

FUNCTIONS
  decode_qrcode
    Usage:

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

    Decode QR Code.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   filename* => *filename*

        (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)

  gen_qrcode
    Usage:

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

    Generate QR Code and by default show it (or save it to a file).

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   filename => *filename*

        If unspecified, will save to a temporary filename and show it with
        Desktop::Open.

        (No description)

    *   text* => *str*

        (No description)

    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,
    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.
