Version::Next - increment module version numbers simply and correctly
version 0.002
use Version::Next; my $new_version = next_version( $old_version );
This module provides a simple, correct way to increment a Perl module version number. It does not attempt to guess what the original version number author intended, it simply increments in the smallest possible fashion. Decimals are incremented like an odometer. Dotted decimals are incremented piecewise and presented in a standardized way.
If more complex version manipulation is necessary, you may wish to consider Perl::Version.
This module uses Sub::Exporter for optional exporting. Nothing is exported by default.
next_version
my $new_version = next_version( $old_version );
Given a string, this function make the smallest logical increment and returns it. The input string is very minimally checked that it resembles a version number. Given undef, the function returns 0.
undef
0
Decimal versions are incremented like an odometer, preserving the original number of decimal places. If an underscore is present (indicating an "alpha" version), its relative position is preserved. Examples:
0.001 -> 0.002 0.999 -> 1.000 0.1229 -> 0.1230 0.12_34 -> 0.12_35 0.12_99 -> 0.13_00
Dotted-decimal versions have the least significant element incremented by one. If the result exceeds 999, the element resets to 0 and the next most significant element is incremented, and so on. Any leading zero padding is removed. Examples:
999
v1.2.3 -> v1.2.4 v1.2.999 -> v1.3.0 v1.999.999 -> v2.0.0 v1.2.3_4 -> v1.2.3_5 v1.2.3_999 -> v1.2.4_0
