Versioning::Scheme::Python - Python (PEP 440) version numbering

VERSION

This document describes version 0.001 of Versioning::Scheme::Python (from Perl distribution Versioning-Scheme-Python), released on 2018-11-18.

SYNOPSIS

 use Versioning::Scheme::Python;

 # checking validity
 Versioning::Scheme::Perl->is_valid_version('1.2.1a1');  # 1
 Versioning::Scheme::Perl->is_valid_version('foo1');     # 0

 # parsing
 $parsed = Versioning::Scheme::Perl->parse_version('1.2.1a1');  # => {base=>[1, 2, 1], prerelease=>["a",1]}

 # normalizing
 Versioning::Scheme::Perl->normalize_version('1.001');  # => '1.1'

 # comparing
 Versioning::Scheme::Perl->cmp_version('1.2.1', '1.2.01');    # 0
 Versioning::Scheme::Perl->cmp_version('1.2.1', '1.2.1a1');   # 1
 Versioning::Scheme::Perl->cmp_version('1.2.1', '1!1.1.0');   # -1

 # bumping
 Versioning::Scheme::Perl->bump_version('1.2.3');                               # => '1.2.4'
 Versioning::Scheme::Perl->bump_version('1.2.3', {num=>2});                     # => '1.2.5'
 Versioning::Scheme::Perl->bump_version('1.2.3', {num=>-1});                    # => '1.2.2'
 Versioning::Scheme::Perl->bump_version('1.2.3', {part=>-2});                   # => '1.3.0'
 Versioning::Scheme::Perl->bump_version('1.2.3', {part=>0});                    # => '2.0.0'
 Versioning::Scheme::Perl->bump_version('1.2.3', {part=>-2, reset_smaller=>0}); # => '1.3.3'
 Versioning::Scheme::Perl->bump_version('1.2.3a1', {part=>'a'});                # => '1.2.3a2'

You can also mix this role into your class.

DESCRIPTION

This role handles Python versioning scheme (as defined in PEP 440) which can be used to version Python-based projects. The role uses Python::Version internally.

METHODS

is_valid_version

parse_version

normalize_version

parse_version

cmp_version

bump_version

Usage:

 Versioning::Scheme::Python->bump_version($v [ , \%opts ]);

Options:

• num => int (default: 1)

• part => int|str (default: -1)

  Use number to bump base version, e.g.:

   Versioning::Scheme::Python->bump_version('1.2.7', {part=>1});                   # => 1.3.0
   Versioning::Scheme::Python->bump_version('1.2.7', {part=>1, reset_smaller=>0}); # => 1.3.7
  
   Versioning::Scheme::Python->bump_version('1.2.7', {part=>-3});                  # => 2.0.0

  Use dev, post, a, b, rc to bump dev/post/alpha/beta/rc numbers, respectively. Will die if version does not have those elements.

  Use epoch to bump epoch number.
