See #444. Apologies for creating the PR first. I should have read the contributing guide first.

Here's some sample code:

package main

import (
	"io"

	tviewfix "github.com/mjwhitta/tview"
	"github.com/rivo/tview"
	hl "gitlab.com/mjwhitta/hilighter"
)

var app *tview.Application

func createTV(title string) (tv *tview.TextView) {
	tv = tview.NewTextView()
	tv.SetBorder(true)
	tv.SetChangedFunc(
		func() {
			app.Draw()
		},
	)
	tv.SetDynamicColors(true)
	tv.SetScrollable(true)
	tv.SetTitle(title)
	tv.SetWordWrap(true)
	tv.SetWrap(true)

	return
}

func main() {
	var after *tview.TextView
	var before *tview.TextView
	var e error
	var layout *tview.Flex
	var newWriter io.Writer
	var oldWriter io.Writer
	var table []string = hl.Table()

	// Top widget
	before = createTV("BEFORE")
	oldWriter = tview.ANSIWriter(before)

	// Bottom widget
	after = createTV("AFTER")
	newWriter = tviewfix.ANSIWriter(after)

	// Layout
	layout = tview.NewFlex()
	layout.AddItem(before, 0, 1, false)
	layout.AddItem(after, 0, 1, false)
	layout.SetDirection(tview.FlexRow)

	// App
	app = tview.NewApplication()
	app.SetRoot(layout, true)

	// Add demo text
	hl.Fprintln(oldWriter, table[0])
	hl.Fprintln(oldWriter, table[1])
	hl.Fprintln(newWriter, table[0])
	hl.Fprintln(newWriter, table[1])

	if e = app.Run(); e != nil {
		hl.PrintlnRed("[!] " + e.Error())
	}
}
