+
+;;; Commentary:
+;;
+;; This package defines a set of routines, windmove-{left,up,right,
+;; down}, for selection of windows in a frame geometrically. For
+;; example, `windmove-right' selects the window immediately to the
+;; right of the currently-selected one. This functionality is similar
+;; to the window-selection controls of the BRIEF editor of yore.
+;;
+;; One subtle point is what happens when the window to the right has
+;; been split vertically; for example, consider a call to
+;; `windmove-right' in this setup:
+;;
+;; -------------
+;; | | A |
+;; | | |
+;; | |-----
+;; | * | | (* is point in the currently
+;; | | B | selected window)
+;; | | |
+;; -------------
+;;
+;; There are (at least) three reasonable things to do:
+;; (1) Always move to the window to the right of the top edge of the
+;; selected window; in this case, this policy selects A.
+;; (2) Always move to the window to the right of the bottom edge of
+;; the selected window; in this case, this policy selects B.
+;; (3) Move to the window to the right of point in the slected
+;; window. This may select either A or B, depending on the
+;; position of point; in the illustrated example, it would select
+;; B.
+;;
+;; Similar issues arise for all the movement functions. Windmove
+;; resolves this problem by allowing the user to specify behavior
+;; through a prefix argument. The cases are thus:
+;; * if no argument is given to the movement functions, or the
+;; argument given is zero, movement is relative to point;
+;; * if a positive argument is given, movement is relative to the top
+;; or left edge of the selected window, depending on whether the
+;; movement is to be horizontal or vertical;
+;; * if a negative argument is given, movement is relative to the
+;; bottom or right edge of the selected window, depending on whether
+;; the movement is to be horizontal or vertical.
+;;
+;;
+;; Another feature enables wrap-around mode when the variable
+;; `windmove-wrap-around' is set to a non-nil value. In this mode,
+;; movement that falls off the edge of the frame will wrap around to
+;; find the window on the opposite side of the frame. Windmove does
+;; the Right Thing about the minibuffer; for example, consider:
+;;
+;; -------------
+;; | * |
+;; |-----------|
+;; | A |
+;; |-----------| (* is point in the currently
+;; | B | C | selected window)
+;; | | |
+;; -------------
+;;
+;; With wraparound enabled, windmove-down will move to A, while
+;; windmove-up will move to the minibuffer if it is active, or to
+;; either B or C depending on the prefix argument.
+;;
+;;
+;; A set of default keybindings is supplied: shift-{left,up,right,down}
+;; invoke the corresponding Windmove function. See the installation
+;; section if you wish to use these keybindings.
+
+
+;; Installation:
+;;
+;; Put the following line in your `.emacs' file:
+;;
+;; (windmove-default-keybindings) ; default keybindings
+;;
+;;
+;; If you wish to enable wrap-around, also add a line like:
+;;
+;; (setq windmove-wrap-around t)
+;;
+;;
+;; Note: If you have an Emacs that manifests a bug that sometimes
+;; causes the occasional creation of a "lost column" between windows,
+;; so that two adjacent windows do not actually touch, you may want to
+;; increase the value of `windmove-window-distance-delta' to 2 or 3:
+;;
+;; (setq windmove-window-distance-delta 2)

+
+;; Implementation overview:
+;;
+;; The conceptual framework behind this code is all fairly simple. We
+;; are on one window; we wish to move to another. The correct window
+;; to move to is determined by the position of point in the current
+;; window as well as the overall window setup.
+;;
+;; Early on, I made the decision to base my implementation around the
+;; built-in function `window-at'. This function takes a frame-based
+;; coordinate, and returns the window that contains it. Using this
+;; function, the job of the various top-level windmove functions can
+;; be decomposed: first, find the current frame-based location of
+;; point; second, manipulate it in some way to give a new location,
+;; that hopefully falls in the window immediately at left (or right,
+;; etc.); third, use `window-at' and `select-window' to select the
+;; window at that new location.
+;;
+;; This is probably not the only possible architecture, and it turns
+;; out to have some inherent cruftiness. (Well, okay, the third step
+;; is pretty clean....) We will consider each step in turn.
+;;
+;; A quick digression about coordinate frames: most of the functions
+;; in the windmove package deal with screen coordinates in one way or
+;; another. These coordinates are always relative to some reference
+;; points. Window-based coordinates have their reference point in the
+;; upper-left-hand corner of whatever window is being talked about;
+;; frame-based coordinates have their reference point in the
+;; upper-left-hand corner of the entire frame (of which the current
+;; window is a component).
+;;
+;; All coordinates are zero-based, which simply means that the
+;; reference point (whatever it is) is assigned the value (x=0, y=0).
+;; X-coordinates grow down the screen, and Y-coordinates grow towards
+;; the right of the screen.
+;;
+;; Okay, back to work. The first step is to gather information about
+;; the frame-based coordinates of point, or rather, the reference
+;; location. The reference location can be point, or the upper-left,
+;; or the lower-right corner of the window; the particular one used is
+;; controlled by the prefix argument to `windmove-left' and all the
+;; rest.
+;;
+;; This work is done by `windmove-reference-loc'. It can figure out
+;; the locations of the corners by calling `window-edges', but to
+;; calculate the frame-based location of point, it calls the workhorse
+;; function `windmove-coordinates-of-position', which itself calls the
+;; incredibly hairy builtin `compute-motion'. There is a good deal of
+;; black magic in getting all the arguments to this function just right.
+;;
+;; The second step is more messy. Conceptually, it is fairly simple:
+;; if we know the reference location, and the coordinates of the
+;; current window, we can "throw" our reference point just over the
+;; appropriate edge of the window, and see what other window is
+;; there. More explicitly, consider this example from the user
+;; documentation above.
+;;
+;; -------------
+;; | | A |
+;; | | |
+;; | |-----
+;; | * | | (* is point in the currently
+;; | | B | selected window)
+;; | | |
+;; -------------
+;;
+;; The asterisk marks the reference point; we wish to move right.
+;; Since we are moving horizontally, the Y coordinate of the new
+;; location will be the same. The X coordinate can be such that it is
+;; just past the edge of the present window. Obviously, the new point
+;; will be inside window B. This in itself is fairly simple: using
+;; the result of `windmove-reference-loc' and `window-edges', all the
+;; necessary math can be performed. (Having said that, there is a
+;; good deal of room for off-by-one errors, and Emacs 19.34, at least,
+;; sometimes manifests a bug where two windows don't actually touch,
+;; so a larger skip is required.) The actual math here is done by
+;; `windmove-other-window-loc'.
+;;
+;; But we can't just pass the result of `windmove-other-window-loc' to
+;; `window-at' directly. Why not? Suppose a move would take us off
+;; the edge of the screen, say to the left. We want to give a
+;; descriptive error message to the user. Or, suppose that a move
+;; would place us in the minibuffer. What if the minibuffer is
+;; inactive?
+;;
+;; Actually, the whole subject of the minibuffer edge of the frame is
+;; rather messy. It turns out that with a sufficiently large delta,
+;; we can fly off the bottom edge of the frame and miss the minibuffer
+;; altogther. This, I think, is never right: if there's a minibuffer
+;; and you're not in it, and you move down, the minibuffer should be
+;; in your way.
+;;
+;; (By the way, I'm not totally sure that the code does the right
+;; thing in really weird cases, like a frame with no minibuffer.)
+;;
+;; So, what we need is some ways to do constraining and such. The
+;; early versions of windmove took a fairly simplistic approach to all
+;; this. When I added the wrap-around option, those internals had to
+;; be rewritten. After a *lot* of futzing around, I came up with a
+;; two-step process that I think is general enough to cover the
+;; relevant cases. (I'm not totally happy with having to pass the
+;; window variable as deep as I do, but we can't have everything.)
+;;
+;; In the first phase, we make sure that the new location is sane.
+;; "Sane" means that we can only fall of the edge of the frame in the
+;; direction we're moving in, and that we don't miss the minibuffer if
+;; we're moving down and not already in the minibuffer. The function
+;; `windmove-constrain-loc-for-movement' takes care of all this.
+;;
+;; Then, we handle the wraparound, if it's enabled. The function
+;; `windmove-wrap-loc-for-movement' takes coordinate values (both X
+;; and Y) that fall off the edge of the frame, and replaces them with
+;; values on the other side of the frame. It also has special
+;; minibuffer-handling code again, because we want to wrap through the
+;; minibuffer if it's not enabled.
+;;
+;; So, that's it. Seems to work. All of this work is done by the fun
+;; function `windmove-find-other-window'.
+;;
+;; So, now we have a window to move to (or nil if something's gone
+;; wrong). The function `windmove-do-window-select' is the main
+;; driver function: it actually does the `select-window'. It is
+;; called by four little convenience wrappers, `windmove-left',
+;; `windmove-up', `windmove-right', and `windmove-down', which make
+;; for convenient keybinding.
+
+
+;; Quick & dirty utility function to add two (x . y) coords.
