I can try, but the idea was half-baked from the start, so I'm not sure how much value it will bring. All I was saying is that depending on how robust TS is, feeding it: and then, knowing that the gap had moved, re-feeding it just the area that corresponds to the places around the boundaries of the gap might yield a speedup. So if the buffer is XYYGGGZ, where G is the gap, and becomes XGGIYYZ while we're scanning because of cursor motion + an insertion, then TS might see XYGIYYZ, due to concurrent mutations; but if we recorded that the gap moved and insertions happened at -#####---, then we can re-feed GGIYY to TS (omitting the Gs, of course), and hopefully it can reuse the parse of X and Z. If X and Z are long enough, that can be valuable. Alternatively, keeping the list of changes allows us to maintain a copy of the buffer that TS uses for scanning, with updates delayed until TS is done scanning.
