Functions

func HasNoError

func HasNoError(action func()) func() error

func HoldContext

func HoldContext(ctx context.Context, action func(context.Context) error) func() error

func Must

func Must(actions ...func() error)

Must execs the actions step by step and raises a panic with error and its stack trace if something went wrong.

func Configure(cmd *cobra.Command) {
	fn.Must(
		func() error { return cmd.MarkFlagRequired("file") },
		func() error { return cmd.MarkFlagRequired("format") },
	)
}

func Repeat

func Repeat(action func() error, times int) error

Repeat repeats the action the required number of times.

func FillByValue(slice []int, value int) error {
	return fn.Repeat(
		fn.HasNoError(func () { slice = append(slice, value) }),
		cap(slice) - len(slice),
	)
}
