GOCUI - Go Console User Interface

Minimalist Go package aimed at creating Console User Interfaces.

• 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...

    "log"

    "github.com/jroimartin/gocui"
)

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

    g.SetManagerFunc(layout)

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

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

func layout(g *gocui.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 != gocui.ErrUnknownView {
            return err
        }
        fmt.Fprintln(v, "Hello world!")
    }
    return nil
}

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