func (t *ToolTracker) FlushAllRemaining(
	width int,
	printedLines int,
	renderMd func(string, int) string,
) FlushToScrollbackResult

Parameters:

  • width: terminal width for rendering
  • printedLines: (unused, kept for API compatibility)
  • maxViewLines: minimum completed segments to keep unflushed for View()
  • renderMd: markdown render function (text, width) -> rendered
