Ok. > Users have complained about this delay. It might be better if they > were able to scroll around, though =E2=80=94 is that what happens with WI= SI? wisi supports partial parse; if a buffer is larger than a user-settable threshold, for font-lock it parses only the request region of the file, expanded to reasonable start/end points. So in that mode, the initial parse of even a very large buffer is fast. However, using that for indentation is problematic, which is why I'm implementing incremental parse. I think continuing to support both will be useful. > But if we have a fully synchronous TS, then that won't be possible > either: it will be a complete Emacs freeze, no? It should only freeze write operations on that buffer, so marking it read-only while waiting for the parse results might be best. --=20 -- Stephe
