termui is a cross-platform and fully-customizable terminal dashboard and widget library built on top of [termbox-go](https://github.com/nsf/termbox-go). It is inspired by [blessed-contrib](https://github.com/yaronn/blessed-contrib) and written purely in Go.

## Installation

Installing from the master branch is recommended:

```bash
go get -u github.com/gizak/termui@master

func main() {
	if err := ui.Init(); err != nil {
		log.Fatalf("failed to initialize termui: %v", err)
	}
	defer ui.Close()

	p := widgets.NewParagraph()
	p.Text = "Hello World!"
	p.SetRect(0, 0, 25, 5)
