Functions

func IsDrySuffix

func IsDrySuffix(file string) bool

func MergeCodes

func MergeCodes(codes []string) string

func ParseEnvDuration

func ParseEnvDuration(name string, defaultValue time.Duration) time.Duration

func ReadFile

func ReadFile(f *os.File) ([]byte, error)

ReadFile reads the named file and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported.

func TrimDrySuffix

func TrimDrySuffix(file string) string

Types

type Features

type Features map[string]bool

Features defines a feature map.

func NewFeatures

func NewFeatures(features ...string) Features

func (*Features) Has

func (f *Features) Has(feature string) bool

Has tells the feature map contains a features.

func (*Features) HasAny

func (f *Features) HasAny(features ...string) bool

HasAny tells the feature map contains any of the features.

func (*Features) IsNop

func (f *Features) IsNop() bool

func (*Features) Setup

func (f *Features) Setup(featuresArr []string)

Setup sets up a feature map by features string, which separates feature names by comma.
