NAME¶
Version::Next - increment module version numbers simply and correctly
VERSION¶
version 0.002
SYNOPSIS¶
use Version::Next;
my $new_version = next_version( $old_version );
DESCRIPTION¶
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.
USAGE¶
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.
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:
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
