Version parser.
$modifierRegex : string
Regex to match pre-release data (sort of).
Due to backwards compatibility:
Numerical-only pre-release identifiers are not supported, see tests.
|--------------|[major].[minor].[patch] -[pre-release] +[build-metadata]
parseNumericAliasPrefix(string $branch) : string|false
Extract numeric prefix from alias, if it is in numeric format, suitable for version comparison.
| string | $branch | Branch name (e.g. 2.1.x-dev) |
Numeric prefix if present (e.g. 2.1.) or false
parseConstraints(string $constraints) : \Composer\Semver\Constraint\ConstraintInterface
Parses a constraint string into MultiConstraint and/or Constraint objects.
| string | $constraints |
parseNameVersionPairs(array $pairs) : array<mixed,array>
Parses an array of strings representing package/version pairs.
The parsing results in an array of arrays, each of which contain a 'name' key with value and optionally a 'version' key with value.
| array | $pairs | a set of package/version pairs separated by ":", "=" or " " |
array of arrays containing a name and (if provided) a version
manipulateVersionString(array $matches, integer $position, integer $increment, string $pad = '0') : string
Increment, decrement, or simply pad a version number.
Support function for \Composer\Semver\parseConstraint()
| array | $matches | Array with version parts in array indexes 1,2,3,4 |
| integer | $position | 1,2,3,4 - which segment of the version to increment/decrement |
| integer | $increment | |
| string | $pad | The string to pad version parts after $position |
The new version
