uilive 是一个用于实时更新终端输出的 Go 库
uilive is a go library for updating terminal output in realtime. It provides a buffered io.Writer that is flushed at a timed interval. uilive powers uiprogress.
Calling uilive.New() will create a new writer. To start rendering, simply call writer.Start() and update the ui by writing to the writer. Full source for the below example is in example/main.go.
writer := uilive.New()
// start listening for updates and render
writer.Start()
for i := 0; i <= 100; i++ {
fmt.Fprintf(writer, "Downloading.. (%d/%d) GB\n", i, 100)
time.Sleep(time.Millisecond * 5)
}
fmt.Fprintln(writer, "Finished: Downloaded 100GB")
writer.Stop() // flush and stop rendering
The above will render
$ go get -v github.com/gosuri/uilive
