Rollerworks Semver Component

A small Semantic Versioning helper library.

Validation Continues Versions. Finding next possible version version increments.

Requirements

You need at least PHP 7.1

Installation

To install this package, add rollerworks/version to your composer.json

$ php composer.phar require rollerworks/version

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Now, Composer will automatically download all required files, and install them for you.

Basic usage

require 'vendor/autoload.php';

use Rollerworks\Component\Version\Version;
use Rollerworks\Component\Version\VersionsValidator;

// Creates an immutable Version value-object.
// Any call to this object will produce a new Version object
$version = Version::fromString('v1.3.2');

$newVersion = $version->increase('major');  // v2.0.0
$newVersion = $version->increase('minor');  // v1.4.0
$newVersion = $version->increase('next');   // v1.4.0
$newVersion = $version->increase('patch');  // v1.3.3
$newVersion = $version->increase('stable'); // v1.4.0

$newVersion = $version->increase('alpha'); // v1.4.0-ALPHA1
$newVersion = $version->increase('beta');  // v1.4.0-BETA1
$newVersion = $version->increase('rc');    // v1.4.0-RC1

// ...
// Increasing minor or patch is prohibited until the meta-ver (alpha,beta,rc) is 0
// For patch this resolves to "next".

$version = Version::fromString('v1.4.0-BETA1');
$newVersion = $version->increase('beta');   // v1.4.0-BETA2
$newVersion = $version->increase('rc');     // v1.4.0-RC1
$newVersion = $version->increase('major');  // v1.4.0
$newVersion = $version->increase('next');   // v1.4.0-BETA2
$newVersion = $version->increase('patch');  // v1.4.0-BETA2
$newVersion = $version->increase('stable'); // v1.4.0

// Version validation
// ... //

$existingVersions = [
    Version::fromString('0.1.0'),
    Version::fromString('v1.0.0-beta1'),
    Version::fromString('v1.0.0-beta2'),
    Version::fromString('v1.0.0-beta6'),
    Version::fromString('v1.0.0-beta7'),
    Version::fromString('1.0.0'),
    Version::fromString('v1.0.1'),
    Version::fromString('v1.1.0'),
    Version::fromString('v2.0.0'),
    Version::fromString('v3.5-beta1'),
];

$validator = new ContinuesVersionsValidator(...$existingVersions); // Expects the versions as a variadic arguments
//$validator = new ContinuesVersionsValidator(); // No existing versions

VersionsValidator::isVersionContinues(Version::fromString('v1.1.1'));      // true
VersionsValidator::isVersionContinues(Version::fromString('1.0.2'));       // true
VersionsValidator::isVersionContinues(Version::fromString('1.1.1.'));      // true
VersionsValidator::isVersionContinues(Version::fromString('2.0.1.'));      // true
VersionsValidator::isVersionContinues(Version::fromString('3.5.0-beta2')); // true
VersionsValidator::isVersionContinues(Version::fromString('3.5.0'));       // true

// A new minor or major version is not considered acceptable when there are already higher
// versions. Only patch releases are accepted then.
VersionsValidator::isVersionContinues(Version::fromString('0.2.0'));        // false
VersionsValidator::isVersionContinues(Version::fromString('v1.0.0-beta8')); // false
VersionsValidator::isVersionContinues(Version::fromString('v1.2'));         // false
VersionsValidator::isVersionContinues(Version::fromString('v2.1'));         // false
VersionsValidator::isVersionContinues(Version::fromString('v3.5-alpha1'));  // false
VersionsValidator::isVersionContinues(Version::fromString('v3.5-beta3'));   // false
VersionsValidator::isVersionContinues(Version::fromString('v3.6'));         // false

// A list of possible versions with respect to the major.minor bounds of any existing version
// For higher major.minor versions then validated only suggests a patch release, otherwise
// all possible increments till the next stable major are suggested.
$possibleVersions = $validator->getPossibleVersions();

Versioning

For transparency and insight into the release cycle, and for striving to maintain backward compatibility, this package is maintained under the Semantic Versioning guidelines as much as possible.

Releases will be numbered with the following format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

  • Breaking backward compatibility bumps the major (and resets the minor and patch)
  • New additions without breaking backward compatibility bumps the minor (and resets the patch)
  • Bug fixes and misc changes bumps the patch
