Original GitHub issue: https://github.com/rivo/tview/issues/914

I have a simple Flex view with two panes, a sort of file explorer on the left and a markdown renderer view on the right

I want to use a custom renderer called glamour and (ideally) simply fmt.Print() the output of the render like it's indicated on the library's wiki.

So I basically want to avoid translating the output from ANSI to TextView using the TranslateANSI() function that defeats the purpose of using this render, is there any way I can do that?

Thanks

This part I don't understand. It seems to me that glamour outputs ANSI escape codes. To display them in a TextView, you'll have to use TranslateANSI(). Or the ANSIWriter if you're dealing with a continuous stream of text.

This part I don't understand. It seems to me that `glamour` outputs ANSI escape codes. To display them in a `TextView`, you'll *have* to use `TranslateANSI()`. Or the [`ANSIWriter`](https://pkg.go.dev/github.com/rivo/tview#ANSIWriter) if you're dealing with a continuous stream of text.

That's what I thought at first but it seems that I lose some formatting by doing so.
By using the TranslateAnsi() function like this:

func render() *tview.TextView {

	in := `# Hello World

This is a simple example of Markdown rendering with Glamour!
Check out the [other examples](https://github.com/charmbracelet/glamour/tree/master/examples) too.

Bye!
`

	out, err := glamour.Render(string(in), "dark")
	if err != nil {
		log.Fatal(err)
	}

	view := tview.NewTextView().SetText(tview.TranslateANSI(out)).SetDynamicColors(true)

	return view
}

I get this output:

While I want to get this:

I read the docs of the function TranslateANSI() and as the name rightly suggests it translates the string while I want to preserve the original formatting.
Is there any way I can avoid to use textView to display the rendered result?
