InputField

A one line InputField:

Code:

package main

import (
	"github.com/gdamore/tcell/v2"
	"github.com/rivo/tview"
)

func main() {
	app := tview.NewApplication()
	inputField := tview.NewInputField().
		SetLabel("Enter a number: ").
		SetFieldWidth(10).
		SetAcceptanceFunc(tview.InputFieldInteger).
		SetDoneFunc(func(key tcell.Key) {
			app.Stop()
		})
	if err := app.SetRoot(inputField, true).SetFocus(inputField).Run(); err != nil {
		panic(err)
	}
}

The InputField class also provides autocomplete functionality. The repo includes two examples for this. The first example, autocomplete.go, illustrates synchronous autocomplete functionality where the data is readily available in the same goroutine.

The second example, autocompleteasync.go, illustrates how autocomplete functionality can be implemented when the autocomplete entries need to be retrieved in a separate goroutine, e.g. by querying an external API.
