They return `Composer\Semver\Constraint\Bound` instances * Added `MultiConstraint::create` to create the most-optimal form of ConstraintInterface from an array of constraint strings ### [1.7.2] 2020-12-03 * Fixed: Allow installing on php 8 ### [1.7.1] 2020-09-27 * Fixed: accidental validation of broken constraints combining ^/~ and wildcards, and -dev suffix allowing weird cases * Fixed: normalization of beta0 and such which was dropping the 0 ### [1.7.0] 2020-09-09 * Added: support for `x || @dev`, not very useful but seen in the wild and failed to validate with 1.5.2/1.6.0 * Added: support for `foobar-dev` being equal to `dev-foobar`, dev-foobar is the official way to write it but we need to support the other for BC and convenience ### [1.6.0] 2020-09-08 * Added: support for constraints like `^2.x-dev` and `~2.x-dev`, not very useful but seen in the wild and failed to validate with 1.5.2 * Fixed: invalid aliases will no longer throw, unless explicitly validated by Composer in the root package ### [1.5.2] 2020-09-08 * Fixed: handling of some invalid -dev versions which were seen as valid * Fixed: some doctypes ### [1.5.1] 2020-01-13 * Fixed: Parsing of aliased version was not validating the alias to be a valid version ### [1.5.0] 2019-03-19 * Added: some support for date versions (e.g. 201903) in `~` operator * Fixed: support for stabilities in `~` operator was inconsistent ### [1.4.2] 2016-08-30 * Fixed: collapsing of complex constraints lead to buggy constraints ### [1.4.1] 2016-06-02 * Changed: branch-like requirements no longer strip build metadata - [composer/semver#38](https://github.com/composer/semver/pull/38). ### [1.4.0] 2016-03-30 * Added: getters on MultiConstraint - [composer/semver#35](https://github.com/composer/semver/pull/35). ### [1.3.0] 2016-02-25 * Fixed: stability parsing - [composer/composer#1234](https://github.com/composer/composer/issues/4889). * Changed: collapse contiguous constraints when possible. ### [1.2.0] 2015-11-10 * Changed: allow multiple numerical identifiers in 'pre-release' version part. * Changed: add more 'v' prefix support. ### [1.1.0] 2015-11-03 * Changed: dropped redundant `test` namespace. * Changed: minor adjustment in datetime parsing normalization. * Changed: `ConstraintInterface` relaxed, setPrettyString is not required anymore. * Changed: `AbstractConstraint` marked deprecated, will be removed in 2.0. * Changed: `Constraint` is now extensible. ### [1.0.0] 2015-09-21 * Break: `VersionConstraint` renamed to `Constraint`. * Break: `SpecificConstraint` renamed to `AbstractConstraint`. * Break: `LinkConstraintInterface` renamed to `ConstraintInterface`. * Break: `VersionParser::parseNameVersionPairs` was removed. * Changed: `VersionParser::parseConstraints` allows (but ignores) build metadata now. * Changed: `VersionParser::parseConstraints` allows (but ignores) prefixing numeric versions with a 'v' now. * Changed: Fixed namespace(s) of test files. * Changed: `Comparator::compare` no longer throws `InvalidArgumentException`. * Changed: `Constraint` now throws `InvalidArgumentException`. ### [0.1.0] 2015-07-23 * Added: `Composer\Semver\Comparator`, various methods to compare versions. * Added: various documents such as README.md, LICENSE, etc. * Added: configuration files for Git, Travis, php-cs-fixer, phpunit. * Break: the following namespaces were renamed: - Namespace: `Composer\Package\Version` -> `Composer\Semver` - Namespace: `Composer\Package\LinkConstraint` -> `Composer\Semver\Constraint` - Namespace: `Composer\Test\Package\Version` -> `Composer\Test\Semver` - Namespace: `Composer\Test\Package\LinkConstraint` -> `Composer\Test\Semver\Constraint` * Changed: code style using php-cs-fixer.

Originally written as part of [composer/composer](https://github.com/composer/composer), now extracted and made available as a stand-alone library. [](https://github.com/composer/semver/actions/workflows/continuous-integration.yml) [](https://github.com/composer/semver/actions/workflows/lint.yml) [](https://github.com/composer/semver/actions/workflows/phpstan.yml) Installation ------------ Install the latest version with: ```bash composer require composer/semver ``` Requirements ------------ * PHP 5.3.2 is required but using the latest version of PHP is highly recommended. Version Comparison ------------------ For details on how versions are compared, refer to the [Versions](https://getcomposer.org/doc/articles/versions.md) article in the documentation section of the [getcomposer.org](https://getcomposer.org) website. Basic usage ----------- ### Comparator The [`Composer\Semver\Comparator`](https://github.com/composer/semver/blob/main/src/Comparator.php) class provides the following methods for comparing versions: * greaterThan($v1, $v2) * greaterThanOrEqualTo($v1, $v2) * lessThan($v1, $v2) * lessThanOrEqualTo($v1, $v2) * equalTo($v1, $v2) * notEqualTo($v1, $v2) Each function takes two version strings as arguments and returns a boolean. For example: ```php use Composer\Semver\Comparator; Comparator::greaterThan('1.25.0', '1.24.0'); // 1.25.0 > 1.24.0 ``` ### Semver The [`Composer\Semver\Semver`](https://github.com/composer/semver/blob/main/src/Semver.php) class provides the following methods: * satisfies($version, $constraints) * satisfiedBy(array $versions, $constraint) * sort($versions) * rsort($versions) ### Intervals The [`Composer\Semver\Intervals`](https://github.com/composer/semver/blob/main/src/Intervals.php) static class provides a few utilities to work with complex constraints or read version intervals from a constraint: ```php use Composer\Semver\Intervals; // Checks whether $candidate is a subset of $constraint Intervals::isSubsetOf(ConstraintInterface $candidate, ConstraintInterface $constraint); // Checks whether $a and $b have any intersection, equivalent to $a->matches($b) Intervals::haveIntersections(ConstraintInterface $a, ConstraintInterface $b); // Optimizes a complex multi constraint by merging all intervals down to the smallest // possible multi constraint. The drawbacks are this is not very fast, and the resulting // multi constraint will have no human readable prettyConstraint configured on it Intervals::compactConstraint(ConstraintInterface $constraint); // Creates an array of numeric intervals and branch constraints representing a given constraint Intervals::get(ConstraintInterface $constraint); // Clears the memoization cache when you are done processing constraints Intervals::clear() ``` See the class docblocks for more details.
