Version::Util - Version-number utilities
This document describes version 0.731 of Version::Util (from Perl distribution Version-Util), released on 2018-06-10.
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.
