VersionParser::$modifierRegex

Regex to match pre-release data (sort of).

Due to backwards compatibility:

  • Instead of enforcing hyphen, an underscore, dot or nothing at all are also accepted.
  • Only stabilities as recognized by Composer are allowed to precede a numerical identifier.
  • Numerical-only pre-release identifiers are not supported, see tests.
