VERSION

This document describes version 0.72 of Version::Util (from Perl distribution Version-Util), released on 2016-03-02.

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

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.
