;; See the "HY-COPY" file for license information.
;;
;; This file is part of GNU Hyperbole.
;;; Commentary:
;;
;; This library provides full interactive control of window and
;; frame sizes and locations utilizing quick single key commands.
;; It has the ability to change from increasing a window height by
;; 5 lines, {.5 h}, to moving a frame 82 pixels, {.82 right-arrow},
;; with just a few keystrokes (the leading . just resets the numeric
;; argument to 0 prior to typing the new number).
;;
;; See the Info manual entry "(hyperbole)HyControl" for reference
;; documentation. See below for key usage information.
;;
;; ----
;;
;; HyControl is invoked via either of two global minor modes under
;; the Hyperbole screen menu, both of which can toggle to the other
;; by pressing {t}. `hycontrol-enable-frames-mode' bound to {C-h h s
;; f} manages visible frame creation, deletion, sizing, position and
;; face zooming (enlarging and shrinking); if called interactively,
;; it stores the current frame configuration for restoration via a
;; press of the `)' key. `hycontrol-enable-windows-mode' manages
;; per frame window creation, deletion, sizing, reframing and face
;; zooming; if called interactively, it stores the current window
;; configuration for restoration via a press of the `)' key.
;; `hycontrol-enable-windows-mode' is typically bound by Hyperbole
;; to {C-c \ } or just use {C-h h s w}. Then press {t} if you want
;; to switch to frame control.
;;
;; With a HyControl minor mode active, a multi-line help summary of
;; most available key bindings is shown in the minibuffer. Simply
;; read this and try each command out to get a feel for it. Below
;; we highlight some of the most unique commands.
;;
;; ----
;;
;; In either HyControl mode, you can instantly create a grid of
;; windows to display many buffers by choosing a number of rows as
;; your first digit, then a number of columns of windows as the
;; second digit and then pressing {@}, e.g. {.26 @} produces 2 rows,
;; each with 6 columns of windows in the selected frame. Grids can
;; be from 1x1 to 9x9 windows. This command also works outside of a
;; HyControl mode when in Dired, Buffer Menu or IBuffer modes with
;; a prefix argument (no preceding period).
;;
;; The buffers displayed by the {@} command are chosen smartly.
;; With a current buffer in Dired, Buffer Menu or IBuffer mode with
;; marked items, the buffers associated with those items are
;; displayed first. Then the most recently used buffers are
;; displayed in each window, first selecting from buffers which
;; match any of the predicate expressions in
;; `hycontrol-display-buffer-predicate-list'. Then, if there are
;; not enough buffers for all windows, the buffers that failed to
;; match to any predicate are used. The default predicate list
;; chooses buffers with attached files. In all cases, buffers whose
;; names start with a space are filtered out. If a prefix argument
;; of 0 is given, a major mode symbol is prompted for and buffers
;; with that major mode are preferred for display instead of those
;; matching the predicate list.
;;
;; ----
;;
;; HyControl allows placement of frames at screen edges and corners
;; using the keys of the numeric keypad, matching their physical
;; layout, e.g. {3} moves to the lower right corner. Press {p} for
;; a prompt with a virtual numeric keypad if you lack a physical one.
;; You can also cycle through all of these placement positions with
;; the {c} key.
;;
;; HyControl can rapidly resize frames to common percentages of
;; screen sizes via a number of commands. Each press of {a} or {A}
;; cycles through resizing the selected frame's width and height
;; respectively to a percentage of the screen given by the lists,
;; `hycontrol-frame-widths' and `hycontrol-frame-heights', e.g. 25%,
;; 50%, etc. The keys: {i} top, {j} left, {k} right, and {m}
;; bottom, first maximize a frame to the respective screen edge and
;; then with successive presses, shrink the frame dimension
;; perpendicular to that edge by 50% while keeping the original edge
;; fixed in place. Try them and you will quickly see how they can
;; help.
;;
;; ----
;;
;; When HyControl creates a new frame, it automatically sizes it to the
;; same size as the previously selected frame and offsets it from that
;; frame by the (X . Y) number of pixels given in the variable,
;; `hycontrol-frame-offset'.
;;
;; A display screen may span multiple physical monitors. To prevent
;; widgets and toolbars at the corners of the screen from being
;; obscured, HyControl can offset each frame from each screen edge
;; by a fixed number of pixels. These offsets are specified by the
;; variable, `hycontrol-screen-offset-alist' and can differ for each
;; type of screen; see its documentation for details. If you change
;; its value, then call `hycontrol-set-screen-offsets' to set any
;; new offset values. `hycontrol-get-screen-offsets' returns the
;; list of offsets in clockwise order starting from the top edge.
;;
;; ----
;;
;; Please note that the frame zoom in/out commands on Z and z will
;; not work unless you have the separately available "zoom-frm.el"
;; library (which itself requires another library). If not available,
;; this command will just beep at you. The window-based zoom commands
;; utilize a built-in Emacs library, so they will always work under
;; any window system. These commands enlarge and shrink the default
;; text face.
