Versioning::Scheme::Semantic - Semantic versioning

VERSION

This document describes version 0.005 of Versioning::Scheme::Semantic (from Perl distribution Versioning-Scheme), released on 2018-10-11.

SYNOPSIS

 use Versioning::Scheme::Semantic;

 # checking validity
 Versioning::Scheme::Semantic->is_valid('0.0.1');    # 1
 Versioning::Scheme::Semantic->is_valid('0.01.1');   # 0 (zero prefix not allowed)
 Versioning::Scheme::Semantic->is_valid('0.1.1.0');  # 0 (only X.Y.Z permitted)

 # normalizing (currently does nothing other than checking for validity)
 Versioning::Scheme::Semantic->normalize('1.2.0'); # => '1.2.0'

 # comparing
 Versioning::Scheme::Semantic->compare('1.2.3', '1.2.3');  # 0
 Versioning::Scheme::Semantic->compare('1.2.3', '1.2.12'); # -1
 Versioning::Scheme::Semantic->compare('1.3.0', '1.2.12'); # 1

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

You can also mix this role into your class.

DESCRIPTION

This role implements the semantic versioning scheme as described in [1]. Version number comprises of three non-negative integers X.Y.Z where zero-prefix is not allowed.

This scheme is not the same as the Perl versioning scheme implemented by version, as the latter has some Perl-specific peculiarities.

Normalizing basically does nothing except checking the validity.

Comparing: Each part is compared numerically from the biggest (leftmost) part.

Bumping: By default the smallest (rightmost) part is increased by 1. You can specify options: num, part, reset_smaller like spacified in Role::Versioning::Scheme.

METHODS
