NAME ^

version::AlphaBeta - Use alphanumeric version objects

SYNOPSIS ^

  use version::AlphaBeta;
  $VERSION = version::AlphaBeta->new("v1.2b");

ABSTRACT ^

  Derived class of version objects which permits use of specific
  alphanumeric version objects, patterned after the version strings
  used by many open source programs, like Mozilla.

DESCRIPTION ^

The base version objects only permit a sequence of numeric values to be used, which is not how some software chooses to label their version strings. This module permits a specific sequence of alpha, beta, release candidate, release, and patch versions to be specified instead of strictly numeric versions. Sorted in increasing order:

  Version     Meaning
  1.3a        1.3 alpha release
  1.3b        1.3 beta release
  1.3b2       1.3 second beta release
  1.3rc       1.3 release candidate
  1.3rc2      1.3 second release candidate
  1.3         1.3 final release
  1.3pl       1.3 first patch release
  1.3pl2      1.3 second patch release

This module can be used as a basis for other subclasses of version objects. The global hash object %IB defines the acceptable non-numeric version parameters:

  %IB = (
      'a' => -3,
      'b' => -2,
      'rc'=> -1,
      ''  =>  0,
      'pl'=>  1
  );

which, if present at all, must be located in the third sub-version.

OBJECT METHODS

This module overrides one of the base version object methods:

Additionally, this module provides two additional logical methods, apart from those already provided by the base version class.

EXPORT

None by default.
