Re: Buffer's point changes when frame closed.

ms> The synchronization between the window point of the selected ms> window and its buffer's point is necessary so that commands ms> *you type* will DTRT, namely act at the point where the user ms> is typing. I think that is wrong. The reason for the synchronization window point -> buffer point is so that _programs_ will act at the point the user was typing or viewing, unless explicitly told to do otherwise. Then while the program is doing whatever it does, the reverse synchronization (buffer point -> window point) is done so that the user is aware of what the program did, again unless the program deliberately conceals any motion it executed. When the user is typing, there is no need whatsoever for a separate concept of buffer point (except in the sense of manipulating the gap, but that's not user-visible). Just insert/delete/twiddle/fix case/ whatever at _window point_, which is always well-defined while the user is typing. (This distinction is slightly incoherent, since of course user typing is meaningless except as it invokes programs. Presumably what I mean is programs that are invoked directly according to stable keymaps, etc, vs programs that are invoked asynchronously from the user's point of view, such as hooks and timers.) ms> There's no reason for this synchronicity to be in ms> place in windows where the user is *not* typing. ms> (In this case, selected windows of unselected frames.) That's a meaningless statement. Synchronicity is a property of how buffer and window points _change_ in response to selection state changes and buffer point motion, not of the particular buffer point <-> window point mapping at any given time or selection state. ms> There'd be no heuristics involved at all. No, just complete nondeterminism. :-) -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
