func CommandExist

func CommandExist(command string) bool

CommandExist will check if command exist or not.

func Fatalf

func Fatalf(format string, v ...interface{})

Fatalf format text and call os.Exit 1.

func GetJson

func GetJson(url string, result interface{}) error

GetJson will fetch to api and decode json result into struct.

func GetRaw

func GetRaw(url string) ([]byte, error)

GetRaw will fetch to api and decode it to raw byte.

func NewSpinner

func NewSpinner() *yacspin.Spinner

NewSpinner will create new spinner.

func ReadFile

func ReadFile(target string) ([]byte, error)

ReadFile will read a file. Params target is the full path of the file. The result will be returned as []byte

func ReadJson

func ReadJson(target string, result interface{}) error

ReadJson will read json file. Params target is the full path of the file. Params result is interface of the file.

func ReadJsonUseNumber

ReadJsonUseNumber will read json file and use json.Number instead float64 for number inside json. Params target is the full path of the file. Params result is interface of the file.

func WriteFile

func WriteFile(target string, data []byte) error

WriteFile will write new file. Params target is the full path of the file.

func WriteJson

func WriteJson(target string, data interface{}) error

WriteJson will write json formated file. Params target is the full path of the file.

Types

type Cl

type Cl struct {
	Current string // The current used colors.
}

Cl are simple color library for the app.

func Colors

func Colors(color string) *Cl

Colors will set current colors.

func (*Cl) Sprint

func (c *Cl) Sprint(v string) string

Sprint will return string formated with colors.

func (*Cl) SprintFunc

func (c *Cl) SprintFunc() func(v string) string

SprintFunc will return Sprint function with colorized text.
