| 24 | ;;; Commentary: |
| 25 | |
| 26 | ;; This is the CUA package which provides a complete emulation of the |
| 27 | ;; standard CUA key bindings (Motif/Windows/Mac GUI) for selecting and |
| 28 | ;; manipulating the region where S-<movement> is used to highlight & |
| 29 | ;; extend the region. |
| 30 | |
| 31 | ;; CUA style key bindings for cut and paste |
| 32 | ;; ---------------------------------------- |
| 33 | |
| 34 | ;; This package allows the C-z, C-x, C-c, and C-v keys to be |
| 35 | ;; bound appropriately according to the Motif/Windows GUI, i.e. |
| 36 | ;; C-z -> undo |
| 37 | ;; C-x -> cut |
| 38 | ;; C-c -> copy |
| 39 | ;; C-v -> paste |
| 40 | ;; |
| 41 | ;; The tricky part is the handling of the C-x and C-c keys which |
| 42 | ;; are normally used as prefix keys for most of emacs' built-in |
| 43 | ;; commands. With CUA they still do!!! |
| 44 | ;; |
| 45 | ;; Only when the region is currently active (and highlighted since |
| 46 | ;; transient-mark-mode is used), the C-x and C-c keys will work as CUA |
| 47 | ;; keys |
| 48 | ;; C-x -> cut |
| 49 | ;; C-c -> copy |
| 50 | ;; When the region is not active, C-x and C-c works as prefix keys! |
| 51 | ;; |
| 52 | ;; This probably sounds strange and difficult to get used to - but |
| 53 | ;; based on my own experience and the feedback from many users of |
| 54 | ;; this package, it actually works very well and users adapt to it |
| 55 | ;; instantly - or at least very quickly. So give it a try! |
| 56 | ;; ... and in the few cases where you make a mistake and accidentally |
| 57 | ;; delete the region - you just undo the mistake (with C-z). |
| 58 | ;; |
| 59 | ;; If you really need to perform a command which starts with one of |
| 60 | ;; the prefix keys even when the region is active, you have three options: |
| 61 | ;; - press the prefix key twice very quickly (within 0.2 seconds), |
| 62 | ;; - press the prefix key and the following key within 0.2 seconds, or |
| 63 | ;; - use the SHIFT key with the prefix key, i.e. C-X or C-C |
| 64 | ;; |
| 65 | ;; This behavior can be customized via the |
| 66 | ;; cua-prefix-override-inhibit-delay variable. |
| 67 | |
| 68 | ;; In addition to using the shifted movement keys, you can also use |
| 69 | ;; [C-space] to start the region and use unshifted movement keys to extend |
| 70 | ;; it. To cancel the region, use [C-space] or [C-g]. |
| 71 | |
| 72 | ;; If you prefer to use the standard emacs cut, copy, paste, and undo |
| 73 | ;; bindings, customize cua-enable-cua-keys to nil. |
| 74 | |
| 75 | |
| 76 | ;; Typing text replaces the region |
| 77 | ;; ------------------------------- |
| 78 | |
| 79 | ;; When the region is active, i.e. highlighted, the text in region is |
| 80 | ;; replaced by the text you type. |
| 81 | |
| 82 | ;; The replaced text is saved in register 0 which can be inserted using |
| 83 | ;; the key sequence M-0 C-v (see the section on register support below). |
| 84 | |
| 85 | ;; If you have just replaced a highlighted region with typed text, |
| 86 | ;; you can repeat the replace with M-v. This will search forward |
| 87 | ;; for a stretch of text identical to the previous contents of the |
| 88 | ;; region (i.e. the contents of register 0) and replace it with the |
| 89 | ;; text you typed to replace the original region. Repeating M-v will |
| 90 | ;; replace the next matching region and so on. |
| 91 | ;; |
| 92 | ;; Example: Suppose you have a line like this |
| 93 | ;; The redo operation will redo the last redoable command |
| 94 | ;; which you want to change into |
| 95 | ;; The repeat operation will repeat the last repeatable command |
| 96 | ;; This is done by highlighting the first occurrence of "redo" |
| 97 | ;; and type "repeat" M-v M-v. |
| 98 | |
| 99 | ;; Note: Since CUA-mode duplicates the functionality of the |
| 100 | ;; delete-selection-mode, that mode is automatically disabled when |
| 101 | ;; CUA-mode is enabled. |
| 102 | |
| 103 | |
| 104 | ;; CUA mode indications |
| 105 | ;; -------------------- |
| 106 | ;; You can choose to let CUA use different cursor colors to indicate |
| 107 | ;; overwrite mode and read-only buffers. For example, the following |
| 108 | ;; setting will use a RED cursor in normal (insertion) mode in |
| 109 | ;; read-write buffers, a YELLOW cursor in overwrite mode in read-write |
| 110 | ;; buffers, and a GREEN cursor read-only buffers: |
| 111 | ;; |
| 112 | ;; (setq cua-normal-cursor-color "red") |
| 113 | ;; (setq cua-overwrite-cursor-color "yellow") |
| 114 | ;; (setq cua-read-only-cursor-color "green") |
| 115 | ;; |
| 116 | |
| 117 | ;; CUA register support |
| 118 | ;; -------------------- |
| 119 | ;; Emacs' standard register support is also based on a separate set of |
| 120 | ;; "register commands". |
| 121 | ;; |
| 122 | ;; CUA's register support is activated by providing a numeric |
| 123 | ;; prefix argument to the C-x, C-c, and C-v commands. For example, |
| 124 | ;; to copy the selected region to register 2, enter [M-2 C-c]. |
| 125 | ;; Or if you have activated the keypad prefix mode, enter [kp-2 C-c]. |
| 126 | ;; |
| 127 | ;; And CUA will copy and paste normal region as well as rectangles |
| 128 | ;; into the registers, i.e. you use exactly the same command for both. |
| 129 | ;; |
| 130 | ;; In addition, the last highlighted text that is deleted (not |
| 131 | ;; copied), e.g. by [delete] or by typing text over a highlighted |
| 132 | ;; region, is automatically saved in register 0, so you can insert it |
| 133 | ;; using [M-0 C-v]. |
| 134 | |
| 135 | ;; CUA rectangle support |
| 136 | ;; --------------------- |
| 137 | ;; Emacs' normal rectangle support is based on interpreting the region |
| 138 | ;; between the mark and point as a "virtual rectangle", and using a |
| 139 | ;; completely separate set of "rectangle commands" [C-x r ...] on the |
| 140 | ;; region to copy, kill, fill a.s.o. the virtual rectangle. |
| 141 | ;; |
| 142 | ;; cua-mode's superior rectangle support uses a true visual |
| 143 | ;; representation of the selected rectangle, i.e. it highlights the |
| 144 | ;; actual part of the buffer that is currently selected as part of the |
| 145 | ;; rectangle. Unlike emacs' traditional rectangle commands, the |
| 146 | ;; selected rectangle always as straight left and right edges, even |
| 147 | ;; when those are in the middle of a TAB character or beyond the end |
| 148 | ;; of the current line. And it does this without actually modifying |
| 149 | ;; the buffer contents (it uses display overlays to visualize the |
| 150 | ;; virtual dimensions of the rectangle). |
| 151 | ;; |
| 152 | ;; This means that cua-mode's rectangles are not limited to the actual |
| 153 | ;; contents of the buffer, so if the cursor is currently at the end of a |
| 154 | ;; short line, you can still extend the rectangle to include more columns |
| 155 | ;; of longer lines in the same rectangle. And you can also have the |
| 156 | ;; left edge of a rectangle start in the middle of a TAB character. |
| 157 | ;; Sounds strange? Try it! |
| 158 | ;; |
| 159 | ;; To start a rectangle, use [C-return] and extend it using the normal |
| 160 | ;; movement keys (up, down, left, right, home, end, C-home, |
| 161 | ;; C-end). Once the rectangle has the desired size, you can cut or |
| 162 | ;; copy it using C-x and C-c (or C-w and M-w), and you can |
| 163 | ;; subsequently insert it - as a rectangle - using C-v (or C-y). So |
| 164 | ;; the only new command you need to know to work with cua-mode |
| 165 | ;; rectangles is C-return! |
| 166 | ;; |
| 167 | ;; Normally, when you paste a rectangle using C-v (C-y), each line of |
| 168 | ;; the rectangle is inserted into the existing lines in the buffer. |
| 169 | ;; If overwrite-mode is active when you paste a rectangle, it is |
| 170 | ;; inserted as normal (multi-line) text. |
| 171 | ;; |
| 172 | ;; If you prefer the traditional rectangle marking (i.e. don't want |
| 173 | ;; straight edges), [M-p] toggles this for the current rectangle, |
| 174 | ;; or you can customize cua-virtual-rectangle-edges. |
| 175 | |
| 176 | ;; And there's more: If you want to extend or reduce the size of the |
| 177 | ;; rectangle in one of the other corners of the rectangle, just use |
| 178 | ;; [return] to move the cursor to the "next" corner. Or you can use |
| 179 | ;; the [M-up], [M-down], [M-left], and [M-right] keys to move the |
| 180 | ;; entire rectangle overlay (but not the contents) in the given |
| 181 | ;; direction. |
| 182 | ;; |
| 183 | ;; [C-return] cancels the rectangle |
| 184 | ;; [C-space] activates the region bounded by the rectangle |
| 185 | |
| 186 | ;; If you type a normal (self-inserting) character when the rectangle is |
| 187 | ;; active, the character is inserted on the "current side" of every line |
| 188 | ;; of the rectangle. The "current side" is the side on which the cursor |
| 189 | ;; is currently located. If the rectangle is only 1 column wide, |
| 190 | ;; insertion will be performed to the left when the cursor is at the |
| 191 | ;; bottom of the rectangle. So, for example, to comment out an entire |
| 192 | ;; paragraph like this one, just place the cursor on the first character |
| 193 | ;; of the first line, and enter the following: |
| 194 | ;; C-return M-} ; ; <space> C-return |
| 195 | |
| 196 | ;; cua-mode's rectangle support also includes all the normal rectangle |
| 197 | ;; functions with easy access: |
| 198 | ;; |
| 199 | ;; [M-a] aligns all words at the left edge of the rectangle |
| 200 | ;; [M-b] fills the rectangle with blanks (tabs and spaces) |
| 201 | ;; [M-c] closes the rectangle by removing all blanks at the left edge |
| 202 | ;; of the rectangle |
| 203 | ;; [M-f] fills the rectangle with a single character (prompt) |
| 204 | ;; [M-i] increases the first number found on each line of the rectangle |
| 205 | ;; by the amount given by the numeric prefix argument (default 1) |
| 206 | ;; It recognizes 0x... as hexadecimal numbers |
| 207 | ;; [M-k] kills the rectangle as normal multi-line text (for paste) |
| 208 | ;; [M-l] downcases the rectangle |
| 209 | ;; [M-m] copies the rectangle as normal multi-line text (for paste) |
| 210 | ;; [M-n] fills each line of the rectangle with increasing numbers using |
| 211 | ;; a supplied format string (prompt) |
| 212 | ;; [M-o] opens the rectangle by moving the highlighted text to the |
| 213 | ;; right of the rectangle and filling the rectangle with blanks. |
| 214 | ;; [M-p] toggles virtual straight rectangle edges |
| 215 | ;; [M-P] inserts tabs and spaces (padding) to make real straight edges |
| 216 | ;; [M-q] performs text filling on the rectangle |
| 217 | ;; [M-r] replaces REGEXP (prompt) by STRING (prompt) in rectangle |
| 218 | ;; [M-R] reverse the lines in the rectangle |
| 219 | ;; [M-s] fills each line of the rectangle with the same STRING (prompt) |
| 220 | ;; [M-t] performs text fill of the rectangle with TEXT (prompt) |
| 221 | ;; [M-u] upcases the rectangle |
| 222 | ;; [M-|] runs shell command on rectangle |
| 223 | ;; [M-'] restricts rectangle to lines with CHAR (prompt) at left column |
| 224 | ;; [M-/] restricts rectangle to lines matching REGEXP (prompt) |
| 225 | ;; [C-?] Shows a brief list of the above commands. |
| 226 | |
| 227 | ;; [M-C-up] and [M-C-down] scrolls the lines INSIDE the rectangle up |
| 228 | ;; and down; lines scrolled outside the top or bottom of the rectangle |
| 229 | ;; are lost, but can be recovered using [C-z]. |
| 230 | |
| 231 | ;; CUA Global Mark |
| 232 | ;; --------------- |
| 233 | ;; The final feature provided by CUA is the "global mark", which |
| 234 | ;; makes it very easy to copy bits and pieces from the same and other |
| 235 | ;; files into the current text. To enable and cancel the global mark, |
| 236 | ;; use [S-C-space]. The cursor will blink when the global mark |
| 237 | ;; is active. The following commands behave differently when the global |
| 238 | ;; mark is set: |
| 239 | ;; <ch> All characters (including newlines) you type are inserted |
| 240 | ;; at the global mark! |
| 241 | ;; [C-x] If you cut a region or rectangle, it is automatically inserted |
| 242 | ;; at the global mark, and the global mark is advanced. |
| 243 | ;; [C-c] If you copy a region or rectangle, it is immediately inserted |
| 244 | ;; at the global mark, and the global mark is advanced. |
| 245 | ;; [C-v] Copies a single character to the global mark. |
| 246 | ;; [C-d] Moves (i.e. deletes and inserts) a single character to the |
| 247 | ;; global mark. |
| 248 | ;; [backspace] deletes the character before the global mark, while |
| 249 | ;; [delete] deletes the character after the global mark. |
| 250 | |
| 251 | ;; [S-C-space] Jumps to and cancels the global mark. |
| 252 | ;; [C-u S-C-space] Cancels the global mark (stays in current buffer). |
| 253 | |
| 254 | ;; [TAB] Indents the current line or rectangle to the column of the |
| 255 | ;; global mark. |

| 662 | |
| 663 | ;; When a prefix key is typed in state [1], cua--prefix-override-handler |

| 1535 | With a prefix argument ARG, enable CUA mode if ARG is positive, |
| 1536 | and disable it otherwise. If called from Lisp, enable the mode |
| 1537 | if ARG is omitted or nil. |
| 1538 | |
| 1539 | CUA mode is a global minor mode. When enabled, typed text |
| 1540 | replaces the active selection, and you can use C-z, C-x, C-c, and |
| 1541 | C-v to undo, cut, copy, and paste in addition to the normal Emacs |
| 1542 | bindings. The C-x and C-c keys only do cut and copy when the |
| 1543 | region is active, so in most cases, they do not conflict with the |
| 1544 | normal function of these prefix keys. |
| 1545 | |
| 1546 | If you really need to perform a command which starts with one of |
| 1547 | the prefix keys even when the region is active, you have three |
| 1548 | options: |
| 1549 | - press the prefix key twice very quickly (within 0.2 seconds), |
| 1550 | - press the prefix key and the following key within 0.2 seconds, or |
| 1551 | - use the SHIFT key with the prefix key, i.e. C-S-x or C-S-c. |
| 1552 | |
| 1553 | You can customize `cua-enable-cua-keys' to completely disable the |
| 1554 | CUA bindings, or `cua-prefix-override-inhibit-delay' to change |
| 1555 | the prefix fallback behavior. |
| 1556 | |
| 1557 | CUA mode manages Transient Mark mode internally. Trying to disable |
| 1558 | Transient Mark mode while CUA mode is enabled does not work; if you |
