type BLHistory ¶

type BLHistory struct {
	// contains filtered or unexported fields
}

BLHistory is a browser-like history: we can add more items to the history; we can go back and forth; when we're a few items back and we add a new item, a new item is added at this place in the history and all the previously existing newer items are dropped; there is no persistence.

A cache can be added to every history item too, but that's a TODO.

func New() *BLHistory

func (h *BLHistory) Add(s string)

func (h *BLHistory) Next() *Item

func (h *BLHistory) Prev() *Item

type Item ¶

type Item struct {
	Time time.Time

	Str string
}
