Variables

var ErrInvalidPlatform = errors.New("invalid platform")

ErrInvalidPlatform represents a platform value error.

var SupportedPlatforms = []Platform{
	Arm64Sonoma,
	Arm64Ventura,
	Arm64Monterey,
	Arm64BigSur,
	Sonoma,
	Ventura,
	Monterey,
	BigSur,
	Catalina,
	Mojave,
	HighSierra,
	X8664Linux,
}

SupportedPlatforms contains all supported platforms.

var ValidPlatformValues = append([]Platform{All}, SupportedPlatforms...)

ValidPlatformValues validates flag values.

Functions

func IsValid

func IsValid(s string) bool

IsValid reports if s is a valid platform.

func NewErrInvalidPlatform

func NewErrInvalidPlatform(value string) error

NewErrInvalidPlatform wraps ErrInvalidPlatform with the invalid platform value.

func Satisfies

func Satisfies(plat Platform, constraint Platform) bool

Satisfies simply checks if the given platform satisfies the constraint. The selected platform will not exceed the constraint.

func SatisfiesOCI

func SatisfiesOCI(ociplat *ocispec.Platform, constraint Platform) bool

SatisfiesOCI checks if the given OCI image platform satisfies the constraint. The selected platform will not exceed the constraint.

func SelectIndex

func SelectIndex(candidates []Platform, constraint Platform) int

SelectIndex selects the most viable platform from a list of candidate platforms. The returned index will be -1 if a compatible platform is not found. The selected platform will not exceed the constraint.

func SelectManifest

func SelectManifest(index *ocispec.Index, constraint Platform) (ocispec.Descriptor, error)

SelectManifest selects the most viable manifest from an OCI image index. The returned index will be -1 if a compatible image is not found. The selected platform will not exceed the constraint.

func SelectManifestIndex

func SelectManifestIndex(index *ocispec.Index, constraint Platform) int

SelectManifestIndex selects the most viable manifest from an OCI image index. The returned index will be -1 if a compatible image is not found. The selected platform will not exceed the constraint.

Types

type Platform

type Platform string

Platform defines a platform.

const (
	Arm64Sonoma   Platform = "arm64_sonoma"   // macOS Sonoma ARM 64-bit
	Arm64Ventura  Platform = "arm64_ventura"  // macOS Sonoma ARM 64-bit

Set implements pflag.Value.

func (Platform) String

func (p Platform) String() string

String implements the fmt.Stringer interface.

func (Platform) Type

func (p Platform) Type() string

Type implements pflag.Value.
