NAME

Version::Next - increment module version numbers simply and correctly

VERSION

version 0.004

SYNOPSIS

   use Version::Next qw/next_version/;
 
   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 must be a "lax" version numbers as defined by the version module. The literal string "undef" is treated as "0" and incremented to "1". Leading or trailing periods have a "0" prepended or appended as appropriate before the version is incremented. For legacy reasons, given no argument, 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
