Prevent clearing terminal at program start

[furysta]

Hello,
I write a program that does some work, prints results one by one, progress bar and summary at the end. It looks something like this:

✓ result
! result
✓ result
! result 
! result
✓ Completed!
────────────────────────────────────────────────────────────────────────────────

The problem is that when you run the program again, the last part of the previous output is erased (like when you call the clear command in the terminal).

The View() function:

func (m model) View() tea.View {
	if !m.ready {
		return tea.NewView("Initializing...")
	}

	status := checkMark.Render("Completed!")
	if m.completed < m.totalNodes {
		status = m.spinner.View() + " " + grayStyle.Render(" Running...")
	}
	if m.quitting {
		status = grayStyle.Render("Interrupted, shutting down...")
	}

	var problems strings.Builder

	if m.quitting || m.done {
		for problem := range m.problems {
			problems.WriteString(warnMark.Render(grayStyle.Render(problem)) + "\n")
		}
	}

	delimiter := grayStyle.Render(strings.Repeat("─", m.width))

	progressBar := m.progress.ViewAs(float64(m.completed) / float64(m.totalNodes))
	progress := fmt.Sprintf("[%3d/%3d] %s\n", m.completed, m.totalNodes, progressBar)

	info := grayStyle.Render("Press Esc, Q or Ctrl+C to exit")

	return tea.NewView(lipgloss.JoinVertical(lipgloss.Left, status, delimiter, problems.String(), progress, info))
}

The results are printed with tea.Println, View is used only for a bottom part (progress bar, status, summary)

The problem is solved. Don't know exactly why, but the cause of the problem was m.progress.ViewAs(...) in View() function. I've replaced it with a m.progress.View() and added proper progress logic into Update() function.

There is an example in package-manager.
