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)
}
}
