func IsConstraint ¶ added in v3.1.0

func IsConstraint(revision string) bool

Returns true if the given revision is not an exact semver and can be parsed as a semver constraint

func IsVersion ¶

func IsVersion(text string) bool

func MaxVersion ¶

func MaxVersion(revision string, tags []string, tagPrefix string) (string, error)

MaxVersion returns the highest version tag satisfying revision, optionally scoped to a tag prefix. If tagPrefix is non-empty, only tags with that prefix are considered; the prefix is stripped before semver comparison and re-added to the returned value. Exact versions and non-constraint strings are returned as-is (with prefix prepended) without consulting the tag list. Returns an error if revision is a constraint and no matching tag is found.
