25 | ;;; Commentary: | |
26 | ||
27 | ;; This is the CUA package which provides a complete emulation of the | |
28 | ;; standard CUA key bindings (Motif/Windows/Mac GUI) for selecting and | |
29 | ;; manipulating the region where S-<movement> is used to highlight & | |
30 | ;; extend the region. | |
31 | ||
34a63289 KS |
32 | ;; CUA style key bindings for cut and paste |
33 | ;; ---------------------------------------- | |
34 | ||
35 | ;; This package allows the C-z, C-x, C-c, and C-v keys to be | |
72cc582e KS |
36 | ;; bound appropriately according to the Motif/Windows GUI, i.e. |
37 | ;; C-z -> undo | |
38 | ;; C-x -> cut | |
39 | ;; C-c -> copy | |
40 | ;; C-v -> paste | |
41 | ;; | |
42 | ;; The tricky part is the handling of the C-x and C-c keys which | |
43 | ;; are normally used as prefix keys for most of emacs' built-in | |
44 | ;; commands. With CUA they still do!!! | |
45 | ;; | |
46 | ;; Only when the region is currently active (and highlighted since | |
47 | ;; transient-mark-mode is used), the C-x and C-c keys will work as CUA | |
48 | ;; keys | |
49 | ;; C-x -> cut | |
50 | ;; C-c -> copy | |
51 | ;; When the region is not active, C-x and C-c works as prefix keys! | |
52 | ;; | |
53 | ;; This probably sounds strange and difficult to get used to - but | |
54 | ;; based on my own experience and the feedback from many users of | |
55 | ;; this package, it actually works very well and users adapt to it | |
a1506d29 | 56 | ;; instantly - or at least very quickly. So give it a try! |
72cc582e KS |
57 | ;; ... and in the few cases where you make a mistake and accidentally |
58 | ;; delete the region - you just undo the mistake (with C-z). | |
59 | ;; | |
60 | ;; If you really need to perform a command which starts with one of | |
61 | ;; the prefix keys even when the region is active, you have three options: | |
62 | ;; - press the prefix key twice very quickly (within 0.2 seconds), | |
1023b169 | 63 | ;; - press the prefix key and the following key within 0.2 seconds, or |
72cc582e KS |
64 | ;; - use the SHIFT key with the prefix key, i.e. C-X or C-C |
65 | ;; | |
fffa137c | 66 | ;; This behavior can be customized via the |
72cc582e KS |
67 | ;; cua-prefix-override-inhibit-delay variable. |
68 | ||
69 | ;; In addition to using the shifted movement keys, you can also use | |
70 | ;; [C-space] to start the region and use unshifted movement keys to extend | |
71 | ;; it. To cancel the region, use [C-space] or [C-g]. | |
72 | ||
73 | ;; If you prefer to use the standard emacs cut, copy, paste, and undo | |
74 | ;; bindings, customize cua-enable-cua-keys to nil. | |
75 | ||

76 | |
77 | ;; Typing text replaces the region | |
78 | ;; ------------------------------- | |
79 | ||
80 | ;; When the region is active, i.e. highlighted, the text in region is | |
81 | ;; replaced by the text you type. | |
82 | ||
83 | ;; The replaced text is saved in register 0 which can be inserted using | |
84 | ;; the key sequence M-0 C-v (see the section on register support below). | |
85 | ||
86 | ;; If you have just replaced a highlighted region with typed text, | |
87 | ;; you can repeat the replace with M-v. This will search forward | |
88 | ;; for a streach of text identical to the previous contents of the | |
89 | ;; region (i.e. the contents of register 0) and replace it with the | |
90 | ;; text you typed to replace the original region. Repeating M-v will | |
91 | ;; replace the next matching region and so on. | |
92 | ;; | |
93 | ;; Example: Suppose you have a line like this | |
94 | ;; The redo operation will redo the last redoable command | |
95 | ;; which you want to change into | |
96 | ;; The repeat operation will repeat the last repeatable command | |
97 | ;; This is done by highlighting the first occurrence of "redo" | |
98 | ;; and type "repeat" M-v M-v. | |
99 | ||
100 | ;; Note: Since CUA-mode duplicates the functionality of the | |
101 | ;; delete-selection-mode, that mode is automatically disabled when | |
102 | ;; CUA-mode is enabled. | |
103 | ||
104 | ||
72cc582e KS |
105 | ;; CUA mode indications |
106 | ;; -------------------- | |
107 | ;; You can choose to let CUA use different cursor colors to indicate | |
108 | ;; overwrite mode and read-only buffers. For example, the following | |
109 | ;; setting will use a RED cursor in normal (insertion) mode in | |
110 | ;; read-write buffers, a YELLOW cursor in overwrite mode in read-write | |
111 | ;; buffers, and a GREEN cursor read-only buffers: | |
112 | ;; | |
113 | ;; (setq cua-normal-cursor-color "red") | |
114 | ;; (setq cua-overwrite-cursor-color "yellow") | |
115 | ;; (setq cua-read-only-cursor-color "green") | |
116 | ;; | |
117 | ||
118 | ;; CUA register support | |
119 | ;; -------------------- | |
120 | ;; Emacs' standard register support is also based on a separate set of | |
121 | ;; "register commands". | |
a1506d29 | 122 | ;; |
72cc582e KS |
123 | ;; CUA's register support is activated by providing a numeric |
124 | ;; prefix argument to the C-x, C-c, and C-v commands. For example, | |
125 | ;; to copy the selected region to register 2, enter [M-2 C-c]. | |
126 | ;; Or if you have activated the keypad prefix mode, enter [kp-2 C-c]. | |
a1506d29 | 127 | ;; |
72cc582e KS |
128 | ;; And CUA will copy and paste normal region as well as rectangles |
129 | ;; into the registers, i.e. you use exactly the same command for both. | |
a1506d29 | 130 | ;; |
72cc582e KS |
131 | ;; In addition, the last highlighted text that is deleted (not |
132 | ;; copied), e.g. by [delete] or by typing text over a highlighted | |
133 | ;; region, is automatically saved in register 0, so you can insert it | |
134 | ;; using [M-0 C-v]. | |
135 | ||
136 | ;; CUA rectangle support | |
137 | ;; --------------------- | |
138 | ;; Emacs' normal rectangle support is based on interpreting the region | |
139 | ;; between the mark and point as a "virtual rectangle", and using a | |
140 | ;; completely separate set of "rectangle commands" [C-x r ...] on the | |
141 | ;; region to copy, kill, fill a.s.o. the virtual rectangle. | |
a1506d29 | 142 | ;; |
85d392cb KS |
143 | ;; cua-mode's superior rectangle support uses a true visual |
144 | ;; representation of the selected rectangle, i.e. it highlights the | |
145 | ;; actual part of the buffer that is currently selected as part of the | |
146 | ;; rectangle. Unlike emacs' traditional rectangle commands, the | |
147 | ;; selected rectangle always as straight left and right edges, even | |
148 | ;; when those are in the middle of a TAB character or beyond the end | |
149 | ;; of the current line. And it does this without actually modifying | |
150 | ;; the buffer contents (it uses display overlays to visualize the | |
151 | ;; virtual dimensions of the rectangle). | |
152 | ;; | |
153 | ;; This means that cua-mode's rectangles are not limited to the actual | |
154 | ;; contents of the buffer, so if the cursor is currently at the end of a | |
155 | ;; short line, you can still extend the rectangle to include more columns | |
156 | ;; of longer lines in the same rectangle. And you can also have the | |
157 | ;; left edge of a rectangle start in the middle of a TAB character. | |
158 | ;; Sounds strange? Try it! | |
159 | ;; | |
c9ee062d | 160 | ;; To start a rectangle, use [C-return] and extend it using the normal |
85d392cb KS |
161 | ;; movement keys (up, down, left, right, home, end, C-home, |
162 | ;; C-end). Once the rectangle has the desired size, you can cut or | |
163 | ;; copy it using C-x and C-c (or C-w and M-w), and you can | |
164 | ;; subsequently insert it - as a rectangle - using C-v (or C-y). So | |
165 | ;; the only new command you need to know to work with cua-mode | |
c9ee062d | 166 | ;; rectangles is C-return! |
72cc582e KS |
167 | ;; |
168 | ;; Normally, when you paste a rectangle using C-v (C-y), each line of | |
169 | ;; the rectangle is inserted into the existing lines in the buffer. | |
170 | ;; If overwrite-mode is active when you paste a rectangle, it is | |
171 | ;; inserted as normal (multi-line) text. | |
a1506d29 | 172 | ;; |
85d392cb KS |
173 | ;; If you prefer the traditional rectangle marking (i.e. don't want |
174 | ;; straight edges), [M-p] toggles this for the current rectangle, | |
175 | ;; or you can customize cua-virtual-rectangle-edges. | |
72cc582e KS |
176 | |
177 | ;; And there's more: If you want to extend or reduce the size of the | |
178 | ;; rectangle in one of the other corners of the rectangle, just use | |
179 | ;; [return] to move the cursor to the "next" corner. Or you can use | |
180 | ;; the [M-up], [M-down], [M-left], and [M-right] keys to move the | |
181 | ;; entire rectangle overlay (but not the contents) in the given | |
182 | ;; direction. | |
183 | ;; | |
c9ee062d | 184 | ;; [C-return] cancels the rectangle |
72cc582e KS |
185 | ;; [C-space] activates the region bounded by the rectangle |
186 | ||
187 | ;; If you type a normal (self-inserting) character when the rectangle is | |
188 | ;; active, the character is inserted on the "current side" of every line | |
189 | ;; of the rectangle. The "current side" is the side on which the cursor | |
190 | ;; is currently located. If the rectangle is only 1 column wide, | |
191 | ;; insertion will be performed to the left when the cursor is at the | |
192 | ;; bottom of the rectangle. So, for example, to comment out an entire | |
193 | ;; paragraph like this one, just place the cursor on the first character | |
194 | ;; of the first line, and enter the following: | |
c9ee062d | 195 | ;; C-return M-} ; ; <space> C-return |
a1506d29 | 196 | |
72cc582e KS |
197 | ;; cua-mode's rectangle support also includes all the normal rectangle |
198 | ;; functions with easy access: | |
199 | ;; | |
200 | ;; [M-a] aligns all words at the left edge of the rectangle | |
201 | ;; [M-b] fills the rectangle with blanks (tabs and spaces) | |
202 | ;; [M-c] closes the rectangle by removing all blanks at the left edge | |
203 | ;; of the rectangle | |
204 | ;; [M-f] fills the rectangle with a single character (prompt) | |
205 | ;; [M-i] increases the first number found on each line of the rectangle | |
206 | ;; by the amount given by the numeric prefix argument (default 1) | |
207 | ;; It recognizes 0x... as hexadecimal numbers | |
208 | ;; [M-k] kills the rectangle as normal multi-line text (for paste) | |
209 | ;; [M-l] downcases the rectangle | |
210 | ;; [M-m] copies the rectangle as normal multi-line text (for paste) | |
211 | ;; [M-n] fills each line of the rectangle with increasing numbers using | |
212 | ;; a supplied format string (prompt) | |
a1506d29 | 213 | ;; [M-o] opens the rectangle by moving the highlighted text to the |
72cc582e | 214 | ;; right of the rectangle and filling the rectangle with blanks. |
85d392cb KS |
215 | ;; [M-p] toggles virtual straight rectangle edges |
216 | ;; [M-P] inserts tabs and spaces (padding) to make real straight edges | |
72cc582e KS |
217 | ;; [M-q] performs text filling on the rectangle |
218 | ;; [M-r] replaces REGEXP (prompt) by STRING (prompt) in rectangle | |
219 | ;; [M-R] reverse the lines in the rectangle | |
220 | ;; [M-s] fills each line of the rectangle with the same STRING (prompt) | |
221 | ;; [M-t] performs text fill of the rectangle with TEXT (prompt) | |
222 | ;; [M-u] upcases the rectangle | |
223 | ;; [M-|] runs shell command on rectangle | |
224 | ;; [M-'] restricts rectangle to lines with CHAR (prompt) at left column | |
225 | ;; [M-/] restricts rectangle to lines matching REGEXP (prompt) | |
226 | ;; [C-?] Shows a brief list of the above commands. | |
227 | ||
228 | ;; [M-C-up] and [M-C-down] scrolls the lines INSIDE the rectangle up | |
229 | ;; and down; lines scrolled outside the top or bottom of the rectangle | |
230 | ;; are lost, but can be recovered using [C-z]. | |
231 | ||
232 | ;; CUA Global Mark | |
a1506d29 | 233 | ;; --------------- |
72cc582e KS |
234 | ;; The final feature provided by CUA is the "global mark", which |
235 | ;; makes it very easy to copy bits and pieces from the same and other | |
236 | ;; files into the current text. To enable and cancel the global mark, | |
237 | ;; use [S-C-space]. The cursor will blink when the global mark | |
238 | ;; is active. The following commands behave differently when the global | |
239 | ;; mark is set: | |
a1506d29 | 240 | ;; <ch> All characters (including newlines) you type are inserted |
72cc582e KS |
241 | ;; at the global mark! |
242 | ;; [C-x] If you cut a region or rectangle, it is automatically inserted | |
243 | ;; at the global mark, and the global mark is advanced. | |
244 | ;; [C-c] If you copy a region or rectangle, it is immediately inserted | |
245 | ;; at the global mark, and the global mark is advanced. | |
246 | ;; [C-v] Copies a single character to the global mark. | |
247 | ;; [C-d] Moves (i.e. deletes and inserts) a single character to the | |
248 | ;; global mark. | |
249 | ;; [backspace] deletes the character before the global mark, while | |
250 | ;; [delete] deltes the character after the global mark. | |
251 | ||
252 | ;; [S-C-space] Jumps to and cancels the global mark. | |
253 | ;; [C-u S-C-space] Cancels the global mark (stays in current buffer). | |
254 | ||
255 | ;; [TAB] Indents the current line or rectangle to the column of the | |
256 | ;; global mark. | |

1533 | When enabled, using shifted movement keys will activate the |
1534 | region (and highlight the region using `transient-mark-mode'), | |
1535 | and typed text replaces the active selection. | |
1536 | ||
1537 | Also when enabled, you can use C-z, C-x, C-c, and C-v to undo, | |
1538 | cut, copy, and paste in addition to the normal Emacs bindings. | |
1539 | The C-x and C-c keys only do cut and copy when the region is | |
1540 | active, so in most cases, they do not conflict with the normal | |
1541 | function of these prefix keys. | |
1542 | ||
1543 | If you really need to perform a command which starts with one of | |
1544 | the prefix keys even when the region is active, you have three | |
1545 | options: | |
1546 | - press the prefix key twice very quickly (within 0.2 seconds), | |
1023b169 | 1547 | - press the prefix key and the following key within 0.2 seconds, or |
3685c8a4 KS |
1548 | - use the SHIFT key with the prefix key, i.e. C-S-x or C-S-c. |
1549 | ||
1550 | You can customize `cua-enable-cua-keys' to completely disable the | |
1551 | CUA bindings, or `cua-prefix-override-inhibit-delay' to change | |
2b3726c0 KS |
1552 | the prefix fallback behavior. |
