NAME
    Module::CheckVersion - Check module (e.g. check latest version) with
    CPAN (or equivalent repo)

VERSION
    This document describes version 0.090 of Module::CheckVersion (from Perl
    distribution Module-CheckVersion), released on 2026-04-07.

SYNOPSIS
    Check latest version of modules:

     use Module::CheckVersion qw(check_module_version);

     my $res = check_module_version(module => 'Clone');
     # sample result: [200, "OK", {latest_version=>'0.38', installed_version=>'0.37', is_latest_version=>0}]

     say "Module Clone is the latest version ($res->[2]{latest_version})"
         if $res->[2]{is_latest_version};

FUNCTIONS
  check_module_version
    Usage:

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

    Check module (e.g. check latest version) with CPAN (or equivalent repo).

    Designed to be more general and able to provide more information in the
    future in addition to mere checking of latest version, but checking
    latest version is currently the only implemented feature.

    Can handle non-CPAN modules, as long as you put the appropriate
    $AUTHORITY in your modules and create the
    "Module::CheckVersion::<scheme>" to handle your authority scheme.

    This function is not exported by default, but exportable.

    Arguments ('*' denotes required arguments):

    *   check_latest_version => *bool* (default: 1)

        (No description)

    *   default_authority_scheme => *str* (default: "cpan")

        If a module does not set $AUTHORITY (which contains string like
        "<scheme>:<extra>" like "cpan:PERLANCAR"), the default authority
        scheme will be determined from this setting. The module
        "Module::CheckVersion::<scheme>" module is used to implement actual
        checking.

        Can also be set to undef, in which case when module's $AUTHORITY is
        not available, will return 412 status.

    *   module* => *str*

        This routine will try to load the module, and retrieve its $VERSION.
        If loading fails will assume module's installed version is undef.

    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.
