;;; Commentary:
|
|
|
|
;; This is the CUA package which provides a complete emulation of the
|
|
;; standard CUA key bindings (Motif/Windows/Mac GUI) for selecting and
|
|
;; manipulating the region where S-<movement> is used to highlight &
|
|
;; extend the region.
|
|
|
|
;; CUA style key bindings for cut and paste
|
|
;; ----------------------------------------
|
|
|
|
;; This package allows the C-z, C-x, C-c, and C-v keys to be
|
|
;; bound appropriately according to the Motif/Windows GUI, i.e.
|
|
;; C-z -> undo
|
|
;; C-x -> cut
|
|
;; C-c -> copy
|
|
;; C-v -> paste
|
|
;;
|
|
;; The tricky part is the handling of the C-x and C-c keys which
|
|
;; are normally used as prefix keys for most of emacs' built-in
|
|
;; commands. With CUA they still do!!!
|
|
;;
|
|
;; Only when the region is currently active (and highlighted since
|
|
;; transient-mark-mode is used), the C-x and C-c keys will work as CUA
|
|
;; keys
|
|
;; C-x -> cut
|
|
;; C-c -> copy
|
|
;; When the region is not active, C-x and C-c works as prefix keys!
|
|
;;
|
|
;; This probably sounds strange and difficult to get used to - but
|
|
;; based on my own experience and the feedback from many users of
|
|
;; this package, it actually works very well and users adapt to it
|
|
;; instantly - or at least very quickly. So give it a try!
|
|
;; ... and in the few cases where you make a mistake and accidentally
|
|
;; delete the region - you just undo the mistake (with C-z).
|
|
;;
|
|
;; If you really need to perform a command which starts with one of
|
|
;; the prefix keys even when the region is active, you have three options:
|
|
;; - press the prefix key twice very quickly (within 0.2 seconds),
|
|
;; - press the prefix key and the following key within 0.2 seconds, or
|
|
;; - use the SHIFT key with the prefix key, i.e. C-X or C-C
|
|
;;
|
|
;; This behaviour can be customized via the
|
|
;; cua-prefix-override-inhibit-delay variable.
|
|
|
|
;; In addition to using the shifted movement keys, you can also use
|
|
;; [C-space] to start the region and use unshifted movement keys to extend
|
|
;; it. To cancel the region, use [C-space] or [C-g].
|
|
|
|
;; If you prefer to use the standard emacs cut, copy, paste, and undo
|
|
;; bindings, customize cua-enable-cua-keys to nil.
|
|
|
|
|
|
;; Typing text replaces the region
|
|
;; -------------------------------
|
|
|
|
;; When the region is active, i.e. highlighted, the text in region is
|
|
;; replaced by the text you type.
|
|
|
|
;; The replaced text is saved in register 0 which can be inserted using
|
|
;; the key sequence M-0 C-v (see the section on register support below).
|
|
|
|
;; If you have just replaced a highlighted region with typed text,
|
|
;; you can repeat the replace with M-v. This will search forward
|
|
;; for a streach of text identical to the previous contents of the
|
|
;; region (i.e. the contents of register 0) and replace it with the
|
|
;; text you typed to replace the original region. Repeating M-v will
|
|
;; replace the next matching region and so on.
|
|
;;
|
|
;; Example: Suppose you have a line like this
|
|
;; The redo operation will redo the last redoable command
|
|
;; which you want to change into
|
|
;; The repeat operation will repeat the last repeatable command
|
|
;; This is done by highlighting the first occurrence of "redo"
|
|
;; and type "repeat" M-v M-v.
|
|
|
|
;; Note: Since CUA-mode duplicates the functionality of the
|
|
;; delete-selection-mode, that mode is automatically disabled when
|
|
;; CUA-mode is enabled.
|
|
|
|
|
|
;; CUA mode indications
|
|
;; --------------------
|
|
;; You can choose to let CUA use different cursor colors to indicate
|
|
;; overwrite mode and read-only buffers. For example, the following
|
|
;; setting will use a RED cursor in normal (insertion) mode in
|
|
;; read-write buffers, a YELLOW cursor in overwrite mode in read-write
|
|
;; buffers, and a GREEN cursor read-only buffers:
|
|
;;
|
|
;; (setq cua-normal-cursor-color "red")
|
|
;; (setq cua-overwrite-cursor-color "yellow")
|
|
;; (setq cua-read-only-cursor-color "green")
|
|
;;
|
|
|
|
;; CUA register support
|
|
;; --------------------
|
|
;; Emacs' standard register support is also based on a separate set of
|
|
;; "register commands".
|
|
;;
|
|
;; CUA's register support is activated by providing a numeric
|
|
;; prefix argument to the C-x, C-c, and C-v commands. For example,
|
|
;; to copy the selected region to register 2, enter [M-2 C-c].
|
|
;; Or if you have activated the keypad prefix mode, enter [kp-2 C-c].
|
|
;;
|
|
;; And CUA will copy and paste normal region as well as rectangles
|
|
;; into the registers, i.e. you use exactly the same command for both.
|
|
;;
|
|
;; In addition, the last highlighted text that is deleted (not
|
|
;; copied), e.g. by [delete] or by typing text over a highlighted
|
|
;; region, is automatically saved in register 0, so you can insert it
|
|
;; using [M-0 C-v].
|
|
|
|
;; CUA rectangle support
|
|
;; ---------------------
|
|
;; Emacs' normal rectangle support is based on interpreting the region
|
|
;; between the mark and point as a "virtual rectangle", and using a
|
|
;; completely separate set of "rectangle commands" [C-x r ...] on the
|
|
;; region to copy, kill, fill a.s.o. the virtual rectangle.
|
|
;;
|
|
;; cua-mode's superior rectangle support uses a true visual
|
|
;; representation of the selected rectangle, i.e. it highlights the
|
|
;; actual part of the buffer that is currently selected as part of the
|
|
;; rectangle. Unlike emacs' traditional rectangle commands, the
|
|
;; selected rectangle always as straight left and right edges, even
|
|
;; when those are in the middle of a TAB character or beyond the end
|
|
;; of the current line. And it does this without actually modifying
|
|
;; the buffer contents (it uses display overlays to visualize the
|
|
;; virtual dimensions of the rectangle).
|
|
;;
|
|
;; This means that cua-mode's rectangles are not limited to the actual
|
|
;; contents of the buffer, so if the cursor is currently at the end of a
|
|
;; short line, you can still extend the rectangle to include more columns
|
|
;; of longer lines in the same rectangle. And you can also have the
|
|
;; left edge of a rectangle start in the middle of a TAB character.
|
|
;; Sounds strange? Try it!
|
|
;;
|
|
;; To start a rectangle, use [C-return] and extend it using the normal
|
|
;; movement keys (up, down, left, right, home, end, C-home,
|
|
;; C-end). Once the rectangle has the desired size, you can cut or
|
|
;; copy it using C-x and C-c (or C-w and M-w), and you can
|
|
;; subsequently insert it - as a rectangle - using C-v (or C-y). So
|
|
;; the only new command you need to know to work with cua-mode
|
|
;; rectangles is C-return!
|
|
;;
|
|
;; Normally, when you paste a rectangle using C-v (C-y), each line of
|
|
;; the rectangle is inserted into the existing lines in the buffer.
|
|
;; If overwrite-mode is active when you paste a rectangle, it is
|
|
;; inserted as normal (multi-line) text.
|
|
;;
|
|
;; If you prefer the traditional rectangle marking (i.e. don't want
|
|
;; straight edges), [M-p] toggles this for the current rectangle,
|
|
;; or you can customize cua-virtual-rectangle-edges.
|
|
|
|
;; And there's more: If you want to extend or reduce the size of the
|
|
;; rectangle in one of the other corners of the rectangle, just use
|
|
;; [return] to move the cursor to the "next" corner. Or you can use
|
|
;; the [M-up], [M-down], [M-left], and [M-right] keys to move the
|
|
;; entire rectangle overlay (but not the contents) in the given
|
|
;; direction.
|
|
;;
|
|
;; [C-return] cancels the rectangle
|
|
;; [C-space] activates the region bounded by the rectangle
|
|
|
|
;; If you type a normal (self-inserting) character when the rectangle is
|
|
;; active, the character is inserted on the "current side" of every line
|
|
;; of the rectangle. The "current side" is the side on which the cursor
|
|
;; is currently located. If the rectangle is only 1 column wide,
|
|
;; insertion will be performed to the left when the cursor is at the
|
|
;; bottom of the rectangle. So, for example, to comment out an entire
|
|
;; paragraph like this one, just place the cursor on the first character
|
|
;; of the first line, and enter the following:
|
|
;; C-return M-} ; ; <space> C-return
|
|
|
|
;; cua-mode's rectangle support also includes all the normal rectangle
|
|
;; functions with easy access:
|
|
;;
|
|
;; [M-a] aligns all words at the left edge of the rectangle
|
|
;; [M-b] fills the rectangle with blanks (tabs and spaces)
|
|
;; [M-c] closes the rectangle by removing all blanks at the left edge
|
|
;; of the rectangle
|
|
;; [M-f] fills the rectangle with a single character (prompt)
|
|
;; [M-i] increases the first number found on each line of the rectangle
|
|
;; by the amount given by the numeric prefix argument (default 1)
|
|
;; It recognizes 0x... as hexadecimal numbers
|
|
;; [M-k] kills the rectangle as normal multi-line text (for paste)
|
|
;; [M-l] downcases the rectangle
|
|
;; [M-m] copies the rectangle as normal multi-line text (for paste)
|
|
;; [M-n] fills each line of the rectangle with increasing numbers using
|
|
;; a supplied format string (prompt)
|
|
;; [M-o] opens the rectangle by moving the highlighted text to the
|
|
;; right of the rectangle and filling the rectangle with blanks.
|
|
;; [M-p] toggles virtual straight rectangle edges
|
|
;; [M-P] inserts tabs and spaces (padding) to make real straight edges
|
|
;; [M-q] performs text filling on the rectangle
|
|
;; [M-r] replaces REGEXP (prompt) by STRING (prompt) in rectangle
|
|
;; [M-R] reverse the lines in the rectangle
|
|
;; [M-s] fills each line of the rectangle with the same STRING (prompt)
|
|
;; [M-t] performs text fill of the rectangle with TEXT (prompt)
|
|
;; [M-u] upcases the rectangle
|
|
;; [M-|] runs shell command on rectangle
|
|
;; [M-'] restricts rectangle to lines with CHAR (prompt) at left column
|
|
;; [M-/] restricts rectangle to lines matching REGEXP (prompt)
|
|
;; [C-?] Shows a brief list of the above commands.
|
|
|
|
;; [M-C-up] and [M-C-down] scrolls the lines INSIDE the rectangle up
|
|
;; and down; lines scrolled outside the top or bottom of the rectangle
|
|
;; are lost, but can be recovered using [C-z].
|
|
|
|
;; CUA Global Mark
|
|
;; ---------------
|
|
;; The final feature provided by CUA is the "global mark", which
|
|
;; makes it very easy to copy bits and pieces from the same and other
|
|
;; files into the current text. To enable and cancel the global mark,
|
|
;; use [S-C-space]. The cursor will blink when the global mark
|
|
;; is active. The following commands behave differently when the global
|
|
;; mark is set:
|
|
;; <ch> All characters (including newlines) you type are inserted
|
|
;; at the global mark!
|
|
;; [C-x] If you cut a region or rectangle, it is automatically inserted
|
|
;; at the global mark, and the global mark is advanced.
|
|
;; [C-c] If you copy a region or rectangle, it is immediately inserted
|
|
;; at the global mark, and the global mark is advanced.
|
|
;; [C-v] Copies a single character to the global mark.
|
|
;; [C-d] Moves (i.e. deletes and inserts) a single character to the
|
|
;; global mark.
|
|
;; [backspace] deletes the character before the global mark, while
|
|
;; [delete] deltes the character after the global mark.
|
|
|
|
;; [S-C-space] Jumps to and cancels the global mark.
|
|
;; [C-u S-C-space] Cancels the global mark (stays in current buffer).
|
|
|
|
;; [TAB] Indents the current line or rectangle to the column of the
|
|
;; global mark.

;; This keymap binds the C-x and C-c prefix keys to the

;; cua--prefix-override-handler function.
|
|
|
|
;; When a prefix key is typed in state [1], cua--prefix-override-handler
|
|
;; will push back the keys already read to the event queue. If input is
|
|
;; pending, it changes directly to state [3]. Otherwise, a short timer [T]
|
|
;; is started, and it changes to state [2].
|
|
|
|
;; In state [2], the cua--prefix-override-keymap is inactive. Instead the
|
|
;; cua--prefix-repeat-keymap is active. This keymap binds C-c C-c and C-x

;; C-x to the cua--prefix-repeat-handler function.
|

;; keys) to the event queue, and changes to state [3].
|
|
|
|
;; The basic cua--cua-keys-keymap binds [C-x timeout] to kill-region and
|
|
;; [C-c timeout] to copy-region-as-kill, so if [T] times out in state [2],
|
|
;; the cua--prefix-override-timeout function will push a `timeout' event on
|
|
;; the event queue, and changes to state [3].
|
|
|
|
;; In state [3] both cua--prefix-override-keymap and cua--prefix-repeat-keymap

CUA bindings, or `cua-prefix-override-inhibit-delay' to change

the prefix fallback behavior."
