Python library

from newversion import Version

version = Version("1.2.3")
next_version = version.bump_minor() # Version("1.3.0")

# bump version same way as SemVer
version.dumps() # "1.2.3"
version.bump_micro().dumps() # "1.2.4"
version.bump_minor().dumps() # "1.3.0"
version.bump_major().dumps() # "2.0.0"

# create and bump pre-releases
version.bump_prerelease().dumps() # "1.2.4rc1"
version.bump_prerelease(bump_release="minor").dumps() # "1.3.0rc1"
version.bump_prerelease("alpha").dumps() # "1.2.4a1"
Version("1.2.3b4").bump_prerelease().dumps() # "1.2.3b5"
version.bump_micro().replace(dev=1234).dumps() # "1.2.4.dev1234"

# and post-releases
version.bump_postrelease().dumps() # "1.2.3.post1"
Version("1.2.3.post3").bump_postrelease(2).dumps() # "1.2.3.post5"

# easily check if this is a pre- or dev release or a stable version
Version("1.2.3").is_stable # True
Version("1.2.3a6").is_stable # False
Version("1.2.3.post3").is_stable # True
Version("1.2.3.post3").get_stable().dumps() # "1.2.3"
