Functions

func BinaryWith

func BinaryWith(binaryVersion, target string) error

BinaryWith tests that this binarie's version is greater or equal than some target version, but not further away than one minor version.

func EnsurePrefixV

func EnsurePrefixV(str string) string

EnsurePrefixV returns the input string prefixed with the letter "v", if the string doesn't already start with that letter.

func FilterNewerVersion

func FilterNewerVersion(currentVersion string, newVersions []string) []string

FilterNewerVersion filters the list of versions to only include versions newer than currentVersion.

func IsValidUpgrade

func IsValidUpgrade(a, b string) error

IsValidUpgrade checks that a and b adhere to a version drift of 1 and b is greater than a.

func NextMinorVersion

func NextMinorVersion(version string) (string, error)

NextMinorVersion returns the next minor version for a given canonical semver. The returned format is vMAJOR.MINOR.

Types

type InvalidUpgradeError

type InvalidUpgradeError struct {
	// contains filtered or unexported fields
}

InvalidUpgradeError present an invalid upgrade. It wraps the source and destination version for improved debuggability.

func NewInvalidUpgradeError

func NewInvalidUpgradeError(from string, to string, innerErr error) *InvalidUpgradeError

NewInvalidUpgradeError returns a new InvalidUpgradeError.

func (InvalidUpgradeError) Error

func (e InvalidUpgradeError) Error() string

Error returns the String representation of this error.

func (InvalidUpgradeError) Unwrap

func (e InvalidUpgradeError) Unwrap() error

Unwrap returns the inner error, which is nil in this case.
