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

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.

For a presentation highlighting this package, compile and run the program found in the "demos/presentation" subdirectory.
