Schlueter Usage: semver [options] <version> [<version> [...]] Prints valid versions sorted by SemVer precedence Options: -r --range <range> Print versions that match the specified range. -i --increment [<level>] Increment a version by the specified level. Level can be one of: major, minor, patch, premajor, preminor, prepatch, or prerelease. Default level is 'patch'. Only one version may be specified. --preid <identifier> Identifier to be used to prefix premajor, preminor, prepatch or prerelease version increments. -l --loose Interpret versions and ranges loosely -p --include-prerelease Always include prerelease versions in range matching -c --coerce Coerce a string into SemVer if possible (does not imply --loose) --rtl Coerce version strings right to left --ltr Coerce version strings left to right (default) Program exits successfully if any valid version satisfies all supplied ranges, and prints all satisfying versions. If no satisfying versions are found, then exits failure. Versions are printed in ascending order, so supplying multiple versions to the utility will just sort them.`) main()
