VERSION

This document describes version 0.004 of App::QRCodeUtils (from Perl distribution App-QRCodeUtils), released on 2024-04-18.

DESCRIPTION

This distributions provides the following command-line utilities:

FUNCTIONS

decode_qrcode

Usage:

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

Decode QR Code.

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]

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.
