NAME Module::CheckLatestVersion - Warn/die when a module is not the latest version VERSION This document describes version 0.001 of Module::CheckLatestVersion (from Perl distribution Module-CheckLatestVersion), released on 2026-04-08. SYNOPSIS In Your/Module.pm: package Your::Module; use Module::CheckVersion; # automatically exports 'check_latest_version' our $VERSION = 1.23; our $AUTHORITY = 'cpan:PERLANCAR'; check_latest_version(); If module is not the latest version (checked against authority) then a warn message is displayed. If the "die" option is set, program will die. FUNCTIONS check_latest_version Usage: check_latest_version([ \%opts, ] [ $mod ]) Check module $mod against authority (default is CPAN), using Module::CheckVersion. $mod defaults to the caller's package. If module is not the latest version, a warning is emitted. When one of these environment variables are set, will skip checking (no-op): "HARNESS_ACTIVE", "RELEASE_TESTING", "AUTOMATED_TESTING". Options: * die Bool. If set to true, will die instead of warn. ENVIRONMENT PERL_MODULE_CHECKLATESTVERSION_DIE Bool. Set default value for the "die" option.

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. COPYRIGHT AND LICENSE This software is copyright (c) 2026 by perlancar .
