Rich Interactive Widgets for Terminal UIs

This Go package provides commonly needed components for terminal based user interfaces.

Among these components are:

• Input forms (include input/password fields, drop-down selections, checkboxes, and buttons)
• Navigable multi-color text views
• Sophisticated navigable table views
• Flexible tree views
• Selectable lists
• Grid, Flexbox and page layouts
• Modal message windows
• An application wrapper

They come with lots of customization options and can be easily extended to fit your needs.

Installation

go get github.com/rivo/tview

Hello World

This basic example creates a box titled "Hello, World!" and displays it in your terminal:

package main

import (
	"github.com/rivo/tview"
)

func main() {
	box := tview.NewBox().SetBorder(true).SetTitle("Hello, world!")
	if err := tview.NewApplication().SetRoot(box, true).Run(); err != nil {
		panic(err)
	}
}

Check out the GitHub Wiki for more examples along with screenshots. Or try the examples in the "demos" subdirectory.
