I have a use case where I want to stream logs to a bubbletea-based TUI, which seems like a perfect use of the
viewport.Model! Particularly since logs can sometimes come at you quite fast, using the terminal built-in scrolling mechanisms seems prudent.However the current
viewport.Modelonly supports fully replacing the current content and re-syncing on every change.Here I've added two methods to
viewport.Model:AppendContent: adds to the end of the current content, and returns a tea.Cmd that "scrolls" the new content into view if necessary (i.e. ifPastBottom()andHighPerformanceRenderingis true).DeleteTopContent: deletesnlines from the top of the current content, and scrolls appropriately if this leaves you "passed the top".Open to feedback on everything here! I'll get around to making a few test apps myself to verify behavior before taking this out of draft.
