var SupportsColor = func() bool {
	b, _ := exec.Command("tput", "colors").CombinedOutput()
	n, _ := strconv.ParseInt(strings.TrimSpace(string(b)), 10, 32)
	return n > 0
}()

SupportsColor returns true if current shell supports ANSI color

Functions ¶

func Base64 ¶

func Base64(string) []byte

Base64 from string

func ColorStr ¶

func ColorStr(c Color, s string) string

ColorStr string

func Cyclic ¶

func Cyclic(uintptr) interface{}

Cyclic reference

func F ¶

func F(v interface{}) string

F is a shortcut for Format with color

func Format ¶

func Format(ts []*Token, theme func(Type) Color) string

Format a list of tokens

func GetPrivateField ¶

func GetPrivateField(v reflect.Value, i int) reflect.Value

GetPrivateField field value via field index TODO: we can use a LRU cache for the copy of the values, but it might be trivial for just testing.

func P ¶

func P(vs ...interface{}) (int, error)

P pretty print the value list vs

func Plain ¶

func Plain(v interface{}) string

Plain is a shortcut for Format with plain color

func StripColor ¶ added in v0.15.2

func StripColor(str string) string

StripColor is copied from https://github.com/acarl005/stripansi

func ToPtr ¶

func ToPtr(interface{}) interface{}

ToPtr converts a Go value to its pointer
