NAME Version::Util - Version-number utilities VERSION This document describes version 0.732 of Version::Util (from Perl distribution Version-Util), released on 2022-09-22. DESCRIPTION This module provides several convenient functions related to version numbers, e.g. for comparing them. FUNCTIONS cmp_version($v1, $v2) => -1|0|1 Equivalent to: version->parse($v1) <=> version->parse($v2) version_eq($v1, $v2) => BOOL version_ne($v1, $v2) => BOOL version_lt($v1, $v2) => BOOL version_le($v1, $v2) => BOOL version_gt($v1, $v2) => BOOL version_ge($v1, $v2) => BOOL version_between($v, $v1, $v2[, $v1b, $v2b, ...]) => BOOL version_in($v, $v1[, $v2, ...]) => BOOL min_version($v1, ...) => $max_v max_version($v1, ...) => $max_v add_version($v, $increment) => $new_v Add $increment to version $v. Both increment and version must match: /\Av?\d{1,3}(?:\.\d{1,3}){0,2}\z/ so trial/dev releases like "v1.2.3_1" are not currently supported. Some examples: 0.1 + 0.1 -> 0.2 0.01 + 0.001 -> 0.011 0.01 + 0.1 -> 0.11 0.9 + 0.1 -> 1.0 0.99 + 0.1 -> 1.09 1.1.0 + 0.0.1 -> 1.1.1 subtract_version($v, $decrement) => $new_v Subtract $decrement from version $v. This is the reverse operation for "add_version". Will die if the result is negative. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at .

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) 2022, 2018, 2014 by perlancar .
