GOTUI - Go Terminal User Interface

Lightweight Go package for creating terminal user interfaces based on gocui

Features

• Minimalist API.
• Views (the "windows" in the GUI) implement the interface io.ReadWriter.
• Support for overlapping views.
• The GUI can be modified at runtime (concurrent-safe).
• Global and view-level keybindings.
• Mouse support.
• Colored text.
• Customizable edition mode.
• Easy to build reusable widgets, complex layouts...

func main() {
	g, err := gotui.NewGui(gotui.OutputNormal)
	if err != nil {
		log.Panicln(err)
	}
	defer g.Close()

	g.SetManagerFunc(layout)

	if err := g.SetKeybinding("", gotui.KeyCtrlC, gotui.ModNone, quit); err != nil {
		log.Panicln(err)
	}

	if err := g.MainLoop(); err != nil && err != gotui.ErrQuit {
		log.Panicln(err)
	}
}

func layout(g *gotui.Gui) error {
	maxX, maxY := g.Size()
	if v, err := g.SetView("hello", maxX/2-7, maxY/2, maxX/2+7, maxY/2+2); err != nil {
		if err != gotui.ErrUnknownView {
			return err
		}
		fmt.Fprintln(v, "Hello world!")
	}
	return nil
}

func quit(g *gotui.Gui, v *gotui.View) error {
	return gotui.ErrQuit
}
