Functions

func CompareWithBuildIdentifiers

func CompareWithBuildIdentifiers(a semver.Version, b semver.Version) int

CompareWithBuildIdentifiers compares 2 version a and b. Perfoms a standard version compare between a and b. If the versions are equal build identifiers will be used to compare further. -1 == a is less than b. 0 == a is equal to b. 1 == a is greater than b.

func ParseMajorMinorPatch

func ParseMajorMinorPatch(version string) (semver.Version, error)

ParseMajorMinorPatch returns a semver.Version from the string provided by looking only at major.minor.patch and stripping everything else out. It requires the version to have a "v" prefix.

func ParseMajorMinorPatchTolerant

func ParseMajorMinorPatchTolerant(version string) (semver.Version, error)

ParseMajorMinorPatchTolerant returns a semver.Version from the string provided by looking only at major.minor.patch and stripping everything else out. It does not require the version to have a "v" prefix.
