Version::Util - Version-number utilities
This document describes version 0.732 of Version::Util (from Perl distribution Version-Util), released on 2022-09-22.
This module provides several convenient functions related to version numbers, e.g. for comparing them.
Equivalent to:
version->parse($v1) <=> version->parse($v2)
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 $decrement from version $v. This is the reverse operation for "add_version".
Will die if the result is negative.

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.
