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.

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.
