NAME
Version::Util - Version-number utilities
VERSION
This document describes version 0.730 of Version::Util (from Perl
distribution Version-Util), released on 2018-01-09.
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.
