NAME

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

VERSION

       version 1.000

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 string "undef" is treated as 0 and
       incremented to 1.  Leading or trailing periods have a 0 (or "v0") prepended or appended as appropriate.
       For legacy reasons, given no argument or a literal "undef" (not the string "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

       NOTE: Due to changes in the interpretation of dotted-decimal version numbers with alpha elements in
       version 0.9913 and later, the notion of the 'next' dotted-decimal alpha is ill-defined.  Version::Next no
       longer supports dotted-decimals with alpha elements and a fatal exception will be thrown if one is
       provided to "next_version".
