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 | ||
34a63289 KS |
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 | |
72cc582e KS |
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 | |
a1506d29 | 55 | ;; instantly - or at least very quickly. So give it a try! |
72cc582e KS |
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), | |
1023b169 | 62 | ;; - press the prefix key and the following key within 0.2 seconds, or |
72cc582e KS |
63 | ;; - use the SHIFT key with the prefix key, i.e. C-X or C-C |
64 | ;; | |
fffa137c | 65 | ;; This behavior can be customized via the |
72cc582e KS |
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 | |
22bcf204 | 87 | ;; for a stretch of text identical to the previous contents of the |
34a63289 KS |
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 | ||
72cc582e KS |
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". | |
a1506d29 | 121 | ;; |
72cc582e KS |
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]. | |
a1506d29 | 126 | ;; |
72cc582e KS |
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. | |
a1506d29 | 129 | ;; |
72cc582e KS |
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. | |
a1506d29 | 141 | ;; |
85d392cb KS |
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 | ;; | |
c9ee062d | 159 | ;; To start a rectangle, use [C-return] and extend it using the normal |
85d392cb KS |
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 | |
c9ee062d | 165 | ;; rectangles is C-return! |
72cc582e KS |
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. | |
a1506d29 | 171 | ;; |
85d392cb KS |
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. | |
72cc582e KS |
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 | ;; | |
c9ee062d | 183 | ;; [C-return] cancels the rectangle |
72cc582e KS |
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: | |
c9ee062d | 194 | ;; C-return M-} ; ; <space> C-return |
a1506d29 | 195 | |
72cc582e KS |
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) | |
a1506d29 | 212 | ;; [M-o] opens the rectangle by moving the highlighted text to the |
72cc582e | 213 | ;; right of the rectangle and filling the rectangle with blanks. |
85d392cb KS |
214 | ;; [M-p] toggles virtual straight rectangle edges |
215 | ;; [M-P] inserts tabs and spaces (padding) to make real straight edges | |
72cc582e KS |
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 | |
a1506d29 | 232 | ;; --------------- |
72cc582e KS |
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: | |
a1506d29 | 239 | ;; <ch> All characters (including newlines) you type are inserted |
72cc582e KS |
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 | |
b762841f | 249 | ;; [delete] deletes the character after the global mark. |
72cc582e KS |
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. | |

1534 | "Toggle Common User Access style editing (CUA mode). |
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. | |
3685c8a4 KS |
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), | |
1023b169 | 1550 | - press the prefix key and the following key within 0.2 seconds, or |
3685c8a4 KS |
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 | |
2b3726c0 KS |
1555 | the prefix fallback behavior. |
