|
|
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.`)
