How To: Use TextView with Spinner (io.Writer) like yacspin

[ghostsquad]

https://github.com/theckman/yacspin supports providing an io.Writer to write to via the spinner config. I tried just giving the spinner the TextView, and hooking up an "on changed" func per the wiki:

myTextView := tview.NewTextView()
myTextView.SetChangedFunc(func() {
	app.Draw()
})
menu.AddItem(myTextView, 1, 1, 1,1, 0, 0, false)

cfg := yacspin.Config{
	Frequency:         refreshInterval,
	CharSet:           yacspin.CharSets[14],
	StopCharacter:     "✓",
	StopColors:        []string{"fgGreen"},
	Writer: myTextView,
}

spinner, err := yacspin.New(cfg)
if err != nil {
	panic(err)
}

err = spinner.Start()
if err != nil {
	panic(err)
}

But I end up with this:

Ignoring for the moment the color incompatibility issue... it appears that the carriage return \r is not being respected, as that's I believe how yacspin returns the the beginning to rewrite.

Is there a correct way to do this?

I found an exceedingly simple alternative to yacspin that will work for my needs here: https://github.com/tj/go-spin
