7 This file describes commands that delete or change text. In this context, | |
8 changing text means deleting the text and replacing it with other text using | |
9 one command. You can undo all of these commands. You can repeat the non-Ex | |
10 commands with the "." command. | |

26 ============================================================================== | |
27 1. Deleting text *deleting* *E470* | |
28 | |
29 ["x]<Del> or *<Del>* *x* *dl* | |
30 ["x]x Delete [count] characters under and after the cursor | |
31 [into register x] (not |linewise|). Does the same as | |
32 "dl". | |
33 The <Del> key does not take a [count]. Instead, it | |
34 deletes the last character of the count. | |
35 See |:fixdel| if the <Del> key does not do what you | |
36 want. See |'whichwrap'| for deleting a line break | |
37 (join lines). {Vi does not support <Del>} | |
38 | |
39 *X* *dh* | |
40 ["x]X Delete [count] characters before the cursor [into | |
41 register x] (not |linewise|). Does the same as "dh". | |
42 Also see |'whichwrap'|. | |
43 | |
44 *d* | |
45 ["x]d{motion} Delete text that {motion} moves over [into register | |
46 x]. See below for exceptions. | |
47 | |
48 *dd* | |
49 ["x]dd Delete [count] lines [into register x] |linewise|. | |
50 | |
51 *D* | |
52 ["x]D Delete the characters under the cursor until the end | |
53 of the line and [count]-1 more lines [into register | |
54 x]; synonym for "d$". | |
55 (not |linewise|) | |
164 | 56 When the '#' flag is in 'cpoptions' the count is |
57 ignored. | |
7 | 58 |
59 {Visual}["x]x or *v_x* *v_d* *v_<Del>* | |
60 {Visual}["x]d or | |
61 {Visual}["x]<Del> Delete the highlighted text [into register x] (for | |
62 {Visual} see |Visual-mode|). {not in Vi} | |
63 | |
64 {Visual}["x]CTRL-H or *v_CTRL-H* *v_<BS>* | |
65 {Visual}["x]<BS> When in Select mode: Delete the highlighted text [into | |
66 register x]. | |
67 | |
68 {Visual}["x]X or *v_X* *v_D* *v_b_D* | |
69 {Visual}["x]D Delete the highlighted lines [into register x] (for | |
70 {Visual} see |Visual-mode|). In Visual block mode, | |
71 "D" deletes the highlighted text plus all text until | |
72 the end of the line. {not in Vi} | |
73 | |
5220 | 74 *:d* *:de* *:del* *:delete* *:dl* *:dp* |
7 | 75 :[range]d[elete] [x] Delete [range] lines (default: current line) [into |
76 register x]. | |
5220 | 77 Note these weird abbreviations: |
78 :dl delete and list | |
79 :dell idem | |
80 :delel idem | |
81 :deletl idem | |
82 :deletel idem | |
83 :dp delete and print | |
84 :dep idem | |
85 :delp idem | |
86 :delep idem | |
87 :deletp idem | |
88 :deletep idem | |
7 | 89 |
90 :[range]d[elete] [x] {count} | |
91 Delete {count} lines, starting with [range] | |
92 (default: current line |cmdline-ranges|) [into | |
93 register x]. | |
94 | |
3492 | 95 These commands delete text. You can repeat them with the `.` command |
96 (except `:d`) and undo them. Use Visual mode to delete blocks of text. See | |
7 | 97 |registers| for an explanation of registers. |
98 | |
99 An exception for the d{motion} command: If the motion is not linewise, the | |
100 start and end of the motion are not in the same line, and there are only | |
101 blanks before the start and after the end of the motion, the delete becomes | |
102 linewise. This means that the delete also removes the line of blanks that you | |
3256 | 103 might expect to remain. Use the |o_v| operator to force the motion to be |
104 characterwise. | |
7 | 105 |
106 Trying to delete an empty region of text (e.g., "d0" in the first column) | |
107 is an error when 'cpoptions' includes the 'E' flag. | |
108 | |
109 *J* | |
110 J Join [count] lines, with a minimum of two lines. | |
111 Remove the indent and insert up to two spaces (see | |
112 below). | |
113 | |
114 *v_J* | |
115 {Visual}J Join the highlighted lines, with a minimum of two | |
116 lines. Remove the indent and insert up to two spaces | |
117 (see below). {not in Vi} | |
118 | |
119 *gJ* | |
120 gJ Join [count] lines, with a minimum of two lines. | |
121 Don't insert or remove any spaces. {not in Vi} | |
122 | |
123 *v_gJ* | |
124 {Visual}gJ Join the highlighted lines, with a minimum of two | |
125 lines. Don't insert or remove any spaces. {not in | |
126 Vi} | |
127 | |
128 *:j* *:join* | |
168 | 129 :[range]j[oin][!] [flags] |
130 Join [range] lines. Same as "J", except with [!] | |
7 | 131 the join does not insert or delete any spaces. |
132 If a [range] has equal start and end values, this | |
133 command does nothing. The default behavior is to | |
134 join the current line with the line below it. | |
135 {not in Vi: !} | |
168 | 136 See |ex-flags| for [flags]. |
7 | 137 |
168 | 138 :[range]j[oin][!] {count} [flags] |
7 | 139 Join {count} lines, starting with [range] (default: |
140 current line |cmdline-ranges|). Same as "J", except | |
141 with [!] the join does not insert or delete any | |
142 spaces. | |
143 {not in Vi: !} | |
168 | 144 See |ex-flags| for [flags]. |
7 | 145 |
146 These commands delete the <EOL> between lines. This has the effect of joining | |
3492 | 147 multiple lines into one line. You can repeat these commands (except `:j`) and |
7 | 148 undo them. |
149 | |
150 These commands, except "gJ", insert one space in place of the <EOL> unless | |
151 there is trailing white space or the next line starts with a ')'. These | |
152 commands, except "gJ", delete any leading white space on the next line. If | |
153 the 'joinspaces' option is on, these commands insert two spaces after a '.', | |
154 '!' or '?' (but if 'cpoptions' includes the 'j' flag, they insert two spaces | |
155 only after a '.'). | |
156 The 'B' and 'M' flags in 'formatoptions' change the behavior for inserting | |
157 spaces before and after a multi-byte character |fo-table|. | |
158 | |
159 | |
160 ============================================================================== | |
161 2. Delete and insert *delete-insert* *replacing* | |
162 | |
163 *R* | |
164 R Enter Replace mode: Each character you type replaces | |
165 an existing character, starting with the character | |
166 under the cursor. Repeat the entered text [count]-1 | |
167 times. See |Replace-mode| for more details. | |
168 | |
169 *gR* | |
170 gR Enter Virtual Replace mode: Each character you type | |
171 replaces existing characters in screen space. So a | |
172 <Tab> may replace several characters at once. | |
173 Repeat the entered text [count]-1 times. See | |
174 |Virtual-Replace-mode| for more details. | |

175 {not available when compiled without the |+vreplace| |
7 | 176 feature} |
177 | |
178 *c* | |
179 ["x]c{motion} Delete {motion} text [into register x] and start | |
180 insert. When 'cpoptions' includes the 'E' flag and | |
181 there is no text to delete (e.g., with "cTx" when the | |
182 cursor is just after an 'x'), an error occurs and | |
183 insert mode does not start (this is Vi compatible). | |
184 When 'cpoptions' does not include the 'E' flag, the | |
185 "c" command always starts insert mode, even if there | |
186 is no text to delete. | |
187 | |
188 *cc* | |
189 ["x]cc Delete [count] lines [into register x] and start | |
190 insert |linewise|. If 'autoindent' is on, preserve | |
191 the indent of the first line. | |
192 | |
193 *C* | |
194 ["x]C Delete from the cursor position to the end of the | |
195 line and [count]-1 more lines [into register x], and | |
196 start insert. Synonym for c$ (not |linewise|). | |
197 | |
198 *s* | |
199 ["x]s Delete [count] characters [into register x] and start | |
200 insert (s stands for Substitute). Synonym for "cl" | |
201 (not |linewise|). | |
202 | |
203 *S* | |
204 ["x]S Delete [count] lines [into register x] and start | |
205 insert. Synonym for "cc" |linewise|. | |
206 | |
207 {Visual}["x]c or *v_c* *v_s* | |
208 {Visual}["x]s Delete the highlighted text [into register x] and | |
209 start insert (for {Visual} see |Visual-mode|). {not | |
210 in Vi} | |
211 | |
212 *v_r* | |
213 {Visual}["x]r{char} Replace all selected characters by {char}. | |
214 | |
215 *v_C* | |
216 {Visual}["x]C Delete the highlighted lines [into register x] and | |
217 start insert. In Visual block mode it works | |
218 differently |v_b_C|. {not in Vi} | |
219 *v_S* | |
220 {Visual}["x]S Delete the highlighted lines [into register x] and | |
221 start insert (for {Visual} see |Visual-mode|). {not | |
222 in Vi} | |
223 *v_R* | |
224 {Visual}["x]R Currently just like {Visual}["x]S. In a next version | |
225 it might work differently. {not in Vi} | |
226 | |
227 Notes: | |
228 - You can end Insert and Replace mode with <Esc>. | |
229 - See the section "Insert and Replace mode" |mode-ins-repl| for the other | |
230 special characters in these modes. | |
231 - The effect of [count] takes place after Vim exits Insert or Replace mode. | |
232 - When the 'cpoptions' option contains '$' and the change is within one line, | |
233 Vim continues to show the text to be deleted and puts a '$' at the last | |
234 deleted character. | |
235 | |
236 See |registers| for an explanation of registers. | |
237 | |
238 Replace mode is just like Insert mode, except that every character you enter | |
239 deletes one character. If you reach the end of a line, Vim appends any | |
240 further characters (just like Insert mode). In Replace mode, the backspace | |
241 key restores the original text (if there was any). (See section "Insert and | |
242 Replace mode" |mode-ins-repl|). | |
243 | |
244 *cw* *cW* | |
1621 | 245 Special case: When the cursor is in a word, "cw" and "cW" do not include the |
246 white space after a word, they only change up to the end of the word. This is | |
247 because Vim interprets "cw" as change-word, and a word does not include the | |
248 following white space. | |
249 {Vi: "cw" when on a blank followed by other blanks changes only the first | |
250 blank; this is probably a bug, because "dw" deletes all the blanks; use the | |
251 'w' flag in 'cpoptions' to make it work like Vi anyway} | |
7 | 252 |
253 If you prefer "cw" to include the space after a word, use this mapping: > | |
254 :map cw dwi | |
1621 | 255 Or use "caw" (see |aw|). |
256 | |
7 | 257 *:c* *:ch* *:change* |
168 | 258 :{range}c[hange][!] Replace lines of text with some different text. |
7 | 259 Type a line containing only "." to stop replacing. |
260 Without {range}, this command changes only the current | |
261 line. | |
168 | 262 Adding [!] toggles 'autoindent' for the time this |
263 command is executed. | |
7 | 264 |
265 ============================================================================== | |
266 3. Simple changes *simple-change* | |
267 | |
268 *r* | |
269 r{char} Replace the character under the cursor with {char}. | |
270 If {char} is a <CR> or <NL>, a line break replaces the | |
271 character. To replace with a real <CR>, use CTRL-V | |
272 <CR>. CTRL-V <NL> replaces with a <Nul>. | |
273 {Vi: CTRL-V <CR> still replaces with a line break, | |
274 cannot replace something with a <CR>} | |

7 | 281 If you give a [count], Vim replaces [count] characters |
282 with [count] {char}s. When {char} is a <CR> or <NL>, | |
283 however, Vim inserts only one <CR>: "5r<CR>" replaces | |
284 five characters with a single line break. | |
285 When {char} is a <CR> or <NL>, Vim performs | |
286 autoindenting. This works just like deleting the | |
287 characters that are replaced and then doing | |
288 "i<CR><Esc>". | |
289 {char} can be entered as a digraph |digraph-arg|. | |
290 |:lmap| mappings apply to {char}. The CTRL-^ command | |
291 in Insert mode can be used to switch this on/off | |
292 |i_CTRL-^|. See |utf-8-char-arg| about using | |
293 composing characters when 'encoding' is Unicode. | |
294 | |
295 *gr* | |
296 gr{char} Replace the virtual characters under the cursor with | |
297 {char}. This replaces in screen space, not file | |
298 space. See |gR| and |Virtual-Replace-mode| for more | |
299 details. As with |r| a count may be given. | |
300 {char} can be entered like with |r|. | |

303 | |
304 *digraph-arg* | |
305 The argument for Normal mode commands like |r| and |t| is a single character. | |
306 When 'cpo' doesn't contain the 'D' flag, this character can also be entered | |
307 like |digraphs|. First type CTRL-K and then the two digraph characters. | |
308 {not available when compiled without the |+digraphs| feature} | |
309 | |
310 *case* | |
311 The following commands change the case of letters. The currently active | |
312 |locale| is used. See |:language|. The LC_CTYPE value matters here. | |
313 | |
314 *~* | |
315 ~ 'notildeop' option: Switch case of the character | |
316 under the cursor and move the cursor to the right. | |
317 If a [count] is given, do that many characters. {Vi: | |
318 no count} | |
319 | |
320 ~{motion} 'tildeop' option: switch case of {motion} text. {Vi: | |
321 tilde cannot be used as an operator} | |

375 *CTRL-A* | |
376 CTRL-A Add [count] to the number or alphabetic character at | |
377 or after the cursor. {not in Vi} | |
378 | |
379 *CTRL-X* | |
380 CTRL-X Subtract [count] from the number or alphabetic | |
381 character at or after the cursor. {not in Vi} | |
382 | |
383 The CTRL-A and CTRL-X commands work for (signed) decimal numbers, unsigned | |
384 octal and hexadecimal numbers and alphabetic characters. This depends on the | |
385 'nrformats' option. | |
36 | 386 - When 'nrformats' includes "octal", Vim considers numbers starting with a '0' |
39 | 387 to be octal, unless the number includes a '8' or '9'. Other numbers are |
388 decimal and may have a preceding minus sign. | |
36 | 389 If the cursor is on a number, the commands apply to that number; otherwise |
390 Vim uses the number to the right of the cursor. | |
7 | 391 - When 'nrformats' includes "hex", Vim assumes numbers starting with '0x' or |
392 '0X' are hexadecimal. The case of the rightmost letter in the number | |
393 determines the case of the resulting hexadecimal number. If there is no | |
394 letter in the current number, Vim uses the previously detected case. | |
36 | 395 - When 'nrformats' includes "alpha", Vim will change the alphabetic character |
396 under or after the cursor. This is useful to make lists with an alphabetic | |
397 index. | |
7 | 398 |
399 For numbers with leading zeros (including all octal and hexadecimal numbers), | |
400 Vim preserves the number of characters in the number when possible. CTRL-A on | |
36 | 401 "0077" results in "0100", CTRL-X on "0x100" results in "0x0ff". |
39 | 402 There is one exception: When a number that starts with a zero is found not to |
403 be octal (it contains a '8' or '9'), but 'nrformats' does include "octal", | |
404 leading zeros are removed to avoid that the result may be recognized as an | |
405 octal number. | |
36 | 406 |
407 Note that when 'nrformats' includes "octal", decimal numbers with leading | |
39 | 408 zeros cause mistakes, because they can be confused with octal numbers. |
7 | 409 |
410 The CTRL-A command is very useful in a macro. Example: Use the following | |
411 steps to make a numbered list. | |
412 | |
413 1. Create the first list entry, make sure it starts with a number. | |
99 | 414 2. qa - start recording into register 'a' |
7 | 415 3. Y - yank the entry |
416 4. p - put a copy of the entry below the first one | |
417 5. CTRL-A - increment the number | |
418 6. q - stop recording | |
419 7. <count>@a - repeat the yank, put and increment <count> times | |
420 | |
421 | |
422 SHIFTING LINES LEFT OR RIGHT *shift-left-right* | |
423 | |
424 *<* | |
425 <{motion} Shift {motion} lines one 'shiftwidth' leftwards. | |

453 | |

168 | 458 :[range]> [flags] Shift {count} [range] lines one 'shiftwidth' right. |
7 | 459 Repeat '>' for shifting multiple 'shiftwidth's. |
168 | 460 See |ex-flags| for [flags]. |
7 | 461 |
168 | 462 :[range]> {count} [flags] |
463 Shift {count} lines one 'shiftwidth' right, starting | |
7 | 464 with [range] (default current line |cmdline-ranges|). |
465 Repeat '>' for shifting multiple 'shiftwidth's. | |
168 | 466 See |ex-flags| for [flags]. |
7 | 467 |
468 The ">" and "<" commands are handy for changing the indentation within | |
469 programs. Use the 'shiftwidth' option to set the size of the white space | |
470 which these commands insert or delete. Normally the 'shiftwidth' option is 8, | |
471 but you can set it to, say, 3 to make smaller indents. The shift leftwards | |
472 stops when there is no indent. The shift right does not affect empty lines. | |
473 | |
474 If the 'shiftround' option is on, the indent is rounded to a multiple of | |
475 'shiftwidth'. | |
476 | |
477 If the 'smartindent' option is on, or 'cindent' is on and 'cinkeys' contains | |
478 '#', shift right does not affect lines starting with '#' (these are supposed | |
479 to be C preprocessor lines that must stay in column 1). | |
480 | |
481 When the 'expandtab' option is off (this is the default) Vim uses <Tab>s as | |
482 much as possible to make the indent. You can use ">><<" to replace an indent | |
483 made out of spaces with the same indent made out of <Tab>s (and a few spaces | |
484 if necessary). If the 'expandtab' option is on, Vim uses only spaces. Then | |
485 you can use ">><<" to replace <Tab>s in the indent by spaces (or use | |
3492 | 486 `:retab!`). |
7 | 487 |
3492 | 488 To move a line several 'shiftwidth's, use Visual mode or the `:` commands. |
7 | 489 For example: > |
490 Vjj4> move three lines 4 indents to the right | |
491 :<<< move current line 3 indents to the left | |
492 :>> 5 move 5 lines 2 indents to the right | |
493 :5>> move line 5 2 indents to the right | |

856 | 498 4.1 Filter commands *filter* |
32 | 499 |
500 A filter is a program that accepts text at standard input, changes it in some | |
501 way, and sends it to standard output. You can use the commands below to send | |
1621 | 502 some text through a filter, so that it is replaced by the filter output. |
32 | 503 Examples of filters are "sort", which sorts lines alphabetically, and |
504 "indent", which formats C program files (you need a version of indent that | |
505 works like a filter; not all versions do). The 'shell' option specifies the | |
506 shell Vim uses to execute the filter command (See also the 'shelltype' | |
507 option). You can repeat filter commands with ".". Vim does not recognize a | |
3492 | 508 comment (starting with '"') after the `:!` command. |
32 | 509 |
510 *!* | |
7 | 511 !{motion}{filter} Filter {motion} text lines through the external |
512 program {filter}. | |
513 | |
514 *!!* | |
515 !!{filter} Filter [count] lines through the external program | |
516 {filter}. | |
517 | |
518 *v_!* | |
519 {Visual}!{filter} Filter the highlighted lines through the external | |
520 program {filter} (for {Visual} see |Visual-mode|). | |
521 {not in Vi} | |
522 | |
523 :{range}![!]{filter} [!][arg] *:range!* | |
524 Filter {range} lines through the external program | |
525 {filter}. Vim replaces the optional bangs with the | |
526 latest given command and appends the optional [arg]. | |
527 Vim saves the output of the filter command in a | |

534 the filtered lines are deleted, unless the | |
535 |:keepmarks| command is used. Example: > | |
536 :keepmarks '<,'>!sort | |
537 < When the number of lines after filtering is less than | |
538 before, marks in the missing lines are deleted anyway. | |

541 ={motion} Filter {motion} lines through the external program | |
542 given with the 'equalprg' option. When the 'equalprg' | |
543 option is empty (this is the default), use the | |
2833 | 544 internal formatting function |C-indenting| and |
545 |'lisp'|. But when 'indentexpr' is not empty, it will | |
546 be used instead |indent-expression|. When Vim was | |
547 compiled without internal formatting then the "indent" | |
548 program is used as a last resort. | |

7 | 577 For each line in [range] replace a match of {pattern} |
578 with {string}. | |
579 For the {pattern} see |pattern|. | |
580 {string} can be a literal string, or something | |
581 special; see |sub-replace-special|. | |
582 When [range] and [count] are omitted, replace in the | |
583 current line only. | |
584 When [count] is given, replace in [count] lines, | |
585 starting with the last line in [range]. When [range] | |
586 is omitted start in the current line. | |
587 Also see |cmdline-ranges|. | |
170 | 588 See |:s_flags| for [flags]. |
7 | 589 |
170 | 590 :[range]s[ubstitute] [flags] [count] |
591 :[range]&[&][flags] [count] *:&* | |
7 | 592 Repeat last :substitute with same search pattern and |
593 substitute string, but without the same flags. You | |
170 | 594 may add [flags], see |:s_flags|. |
3492 | 595 Note that after `:substitute` the '&' flag can't be |
7 | 596 used, it's recognized as a pattern separator. |
3492 | 597 The space between `:substitute` and the 'c', 'g' and |
7 | 598 'r' flags isn't required, but in scripts it's a good |
599 idea to keep it to avoid confusion. | |
600 | |
170 | 601 :[range]~[&][flags] [count] *:~* |
7 | 602 Repeat last substitute with same substitute string |
603 but with last used search pattern. This is like | |
3492 | 604 `:&r`. See |:s_flags| for [flags]. |
7 | 605 |
170 | 606 *&* |
3492 | 607 & Synonym for `:s` (repeat last substitute). Note |
7 | 608 that the flags are not remembered, thus it might |
3492 | 609 actually work differently. You can use `:&&` to keep |
7 | 610 the flags. |
611 | |
170 | 612 *g&* |
3920 | 613 g& Synonym for `:%s//~/&` (repeat last substitute with |
614 last search pattern on all lines with the same flags). | |
4186 | 615 For example, when you first do a substitution with |
3920 | 616 `:s/pattern/repl/flags` and then `/search` for |
617 something else, `g&` will do `:%s/search/repl/flags`. | |
7 | 618 Mnemonic: global substitute. {not in Vi} |
619 | |
620 *:snomagic* *:sno* | |
3492 | 621 :[range]sno[magic] ... Same as `:substitute`, but always use 'nomagic'. |

624 *:smagic* *:sm* | |
3492 | 625 :[range]sm[agic] ... Same as `:substitute`, but always use 'magic'. |
7 | 626 {not in Vi} |
627 | |
628 *:s_flags* | |
629 The flags that you can use for the substitute commands: | |
630 | |
631 [&] Must be the first one: Keep the flags from the previous substitute | |
632 command. Examples: > | |
633 :&& | |
634 :s/this/that/& | |
3492 | 635 < Note that `:s` and `:&` don't keep the flags. |
7 | 636 {not in Vi} |
637 | |
638 [c] Confirm each substitution. Vim highlights the matching string (with | |
639 |hl-IncSearch|). You can type: *:s_c* | |
640 'y' to substitute this match | |
641 'l' to substitute this match and then quit ("last") | |
642 'n' to skip this match | |
643 <Esc> to quit substituting | |

7 | 650 If the 'edcompatible' option is on, Vim remembers the [c] flag and |
651 toggles it each time you use it, but resets it when you give a new | |
652 search pattern. | |
653 {not in Vi: highlighting of the match, other responses than 'y' or 'n'} | |
654 | |
655 [e] When the search pattern fails, do not issue an error message and, in | |
656 particular, continue in maps as if no error occurred. This is most | |
657 useful to prevent the "No match" error from breaking a mapping. Vim | |
658 does not suppress the following error messages, however: | |
659 Regular expressions can't be delimited by letters | |
660 \ should be followed by /, ? or & | |
661 No previous substitute regular expression | |
662 Trailing characters | |
663 Interrupted | |
664 {not in Vi} | |
665 | |
666 [g] Replace all occurrences in the line. Without this argument, | |
667 replacement occurs only for the first occurrence in each line. If | |
668 the 'edcompatible' option is on, Vim remembers this flag and toggles | |
669 it each time you use it, but resets it when you give a new search | |
670 pattern. If the 'gdefault' option is on, this flag is on by default | |
671 and the [g] argument switches it off. | |
672 | |
673 [i] Ignore case for the pattern. The 'ignorecase' and 'smartcase' options | |
674 are not used. | |
675 {not in Vi} | |
676 | |
677 [I] Don't ignore case for the pattern. The 'ignorecase' and 'smartcase' | |
678 options are not used. | |
679 {not in Vi} | |
680 | |
170 | 681 [n] Report the number of matches, do not actually substitute. The [c] |
682 flag is ignored. The matches are reported as if 'report' is zero. | |
683 Useful to |count-items|. | |
3750 | 684 If \= |sub-replace-expression| is used, the expression will be |
685 evaluated in the |sandbox| at every match. | |
170 | 686 |
7 | 687 [p] Print the line containing the last substitute. |
168 | 688 |
689 [#] Like [p] and prepend the line number. | |
690 | |
1121 | 691 [l] Like [p] but print the text like |:list|. |
7 | 692 |
3492 | 693 [r] Only useful in combination with `:&` or `:s` without arguments. `:&r` |
694 works the same way as `:~`: When the search pattern is empty, use the | |
7 | 695 previously used search pattern instead of the search pattern from the |
3492 | 696 last substitute or `:global`. If the last command that did a search |
697 was a substitute or `:global`, there is no effect. If the last | |
7 | 698 command was a search command such as "/", use the pattern from that |
699 command. | |
3492 | 700 For `:s` with an argument this already happens: > |
7 | 701 :s/blue/red/ |
702 /green | |
703 :s//red/ or :~ or :&r | |
704 < The last commands will replace "green" with "red". > | |
705 :s/blue/red/ | |
706 /green | |
707 :& | |
708 < The last command will replace "blue" with "red". | |
709 {not in Vi} | |
710 | |
711 Note that there is no flag to change the "magicness" of the pattern. A | |
1621 | 712 different command is used instead, or you can use |/\v| and friends. The |
713 reason is that the flags can only be found by skipping the pattern, and in | |
714 order to skip the pattern the "magicness" must be known. Catch 22! | |
7 | 715 |
716 If the {pattern} for the substitute command is empty, the command uses the | |
3492 | 717 pattern from the last substitute or `:global` command. If there is none, but |
2725 | 718 there is a previous search pattern, that one is used. With the [r] flag, the |
3492 | 719 command uses the pattern from the last substitute, `:global`, or search |
7 | 720 command. |
721 | |
1121 | 722 If the {string} is omitted the substitute is done as if it's empty. Thus the |
723 matched pattern is deleted. The separator after {pattern} can also be left | |
724 out then. Example: > | |
725 :%s/TESTING | |
726 This deletes "TESTING" from all lines, but only one per line. | |
727 | |
7 | 728 For compatibility with Vi these two exceptions are allowed: |
729 "\/{string}/" and "\?{string}?" do the same as "//{string}/r". | |
730 "\&{string}&" does the same as "//{string}/". | |
731 *E146* | |
732 Instead of the '/' which surrounds the pattern and replacement string, you | |
1121 | 733 can use any other single-byte character, but not an alphanumeric character, |
734 '\', '"' or '|'. This is useful if you want to include a '/' in the search | |
735 pattern or replacement string. Example: > | |
7 | 736 :s+/+//+ |
737 | |
1621 | 738 For the definition of a pattern, see |pattern|. In Visual block mode, use |
739 |/\%V| in the pattern to have the substitute work in the block only. | |
740 Otherwise it works on whole lines anyway. | |
7 | 741 |
742 *sub-replace-special* *:s\=* | |
743 When the {string} starts with "\=" it is evaluated as an expression, see | |
2908 | 744 |sub-replace-expression|. You can use that for complex replacement or special |
745 characters. | |
746 | |
452 | 747 Otherwise these characters in {string} have a special meaning: |
168 | 748 *:s%* |
843 | 749 When {string} is equal to "%" and '/' is included with the 'cpoptions' option, |
2908 | 750 then the {string} of the previous substitute command is used, see |cpo-/| |

788 - magic is always set without regard to 'magic'. | |
789 - A ~ inserts a tilde literally. | |
790 - <CR> and \r inserts a carriage-return (CTRL-M). | |
791 - \<CR> does not have a special meaning. it's just one of \x. | |

797 :s/$/\^M/ modifies "abcde" to "abcde^M" | |
772 | 798 :s/\w\+/\u\0/g modifies "bla bla" to "Bla Bla" |
4264 | 799 :s/\w\+/\L\u/g modifies "BLA bla" to "Bla Bla" |
800 | |
801 Note: "\L\u" can be used to capitalize the first letter of a word. This is | |
802 not compatible with Vi and older versions of Vim, where the "\u" would cancel | |
803 out the "\L". Same for "\U\l". | |
7 | 804 |
805 Note: In previous versions CTRL-V was handled in a special way. Since this is | |
806 not Vi compatible, this was removed. Use a backslash instead. | |
807 | |
808 command text result ~ | |
809 :s/aa/a^Ma/ aa a<line-break>a | |
810 :s/aa/a\^Ma/ aa a^Ma | |
811 :s/aa/a\\^Ma/ aa a\<line-break>a | |
812 | |
813 (you need to type CTRL-V <CR> to get a ^M here) | |
814 | |
815 The numbering of "\1", "\2" etc. is done based on which "\(" comes first in | |
816 the pattern (going left to right). When a parentheses group matches several | |
817 times, the last one will be used for "\1", "\2", etc. Example: > | |
818 :s/\(\(a[a-d] \)*\)/\2/ modifies "aa ab x" to "ab x" | |
819 | |
820 When using parentheses in combination with '|', like in \([ab]\)\|\([cd]\), | |
821 either the first or second pattern in parentheses did not match, so either | |
822 \1 or \2 is empty. Example: > | |
823 :s/\([ab]\)\|\([cd]\)/\1x/g modifies "a b c d" to "ax bx x x" | |
824 < | |
825 | |
826 Substitute with an expression *sub-replace-expression* | |
270 | 827 *sub-replace-\=* |
828 When the substitute string starts with "\=" the remainder is interpreted as an | |
2908 | 829 expression. This does not work recursively: a |substitute()| function inside |
7 | 830 the expression cannot use "\=" for the substitute string. |
831 | |
832 The special meaning for characters as mentioned at |sub-replace-special| does | |
2908 | 833 not apply except for "<CR>". A <NL> character is used as a line break, you |
834 can get one with a double-quote string: "\n". Prepend a backslash to get a | |
835 real <NL> character (which will be a NUL in the file). | |
7 | 836 |
2908 | 837 The "\=" notation can also be used inside the third argument {sub} of |
838 |substitute()| function. In this case, the special meaning for characters as | |
839 mentioned at |sub-replace-special| does not apply at all. Especially, <CR> and | |
840 <NL> are interpreted not as a line break but as a carriage-return and a | |
841 new-line respectively. | |
7 | 842 |
714 | 843 When the result is a |List| then the items are joined with separating line |
844 breaks. Thus each item becomes a line, except that they can contain line | |
845 breaks themselves. | |
846 | |
7 | 847 The whole matched text can be accessed with "submatch(0)". The text matched |
848 with the first pair of () with "submatch(1)". Likewise for further | |
849 sub-matches in (). | |
850 | |
851 Be careful: The separation character must not appear in the expression! | |
852 Consider using a character like "@" or ":". There is no problem if the result | |
853 of the expression contains the separation character. | |
854 | |
452 | 855 Examples: > |
7 | 856 :s@\n@\="\r" . expand("$HOME") . "\r"@ |
452 | 857 This replaces an end-of-line with a new line containing the value of $HOME. > |
858 | |
859 s/E/\="\<Char-0x20ac>"/g | |

3492 | 879 *:ret* *:retab* *:retab!* |
7 | 880 :[range]ret[ab][!] [new_tabstop] |
881 Replace all sequences of white-space containing a | |
882 <Tab> with new strings of white-space using the new | |
883 tabstop value given. If you do not specify a new | |
884 tabstop size or it is zero, Vim uses the current value | |
885 of 'tabstop'. | |
886 The current value of 'tabstop' is always used to | |
887 compute the width of existing tabs. | |
888 With !, Vim also replaces strings of only normal | |
889 spaces with tabs where appropriate. | |
890 With 'expandtab' on, Vim replaces all tabs with the | |
891 appropriate number of spaces. | |
892 This command sets 'tabstop' to the new value given, | |
893 and if performed on the whole file, which is default, | |
894 should not make any visible change. | |
895 Careful: This command modifies any <Tab> characters | |
896 inside of strings in a C program. Use "\t" to avoid | |
897 this (that's a good habit anyway). | |
3492 | 898 `:retab!` may also change a sequence of spaces by |
7 | 899 <Tab> characters, which can mess up a printf(). |

3492 | 1012 Otherwise, paste from the unnamed register |
1013 |quote_quote|. | |
7 | 1014 The register can also be '=' followed by an optional |
1015 expression. The expression continues until the end of | |
1016 the command. You need to escape the '|' and '"' | |
1017 characters to prevent them from terminating the | |
1018 command. Example: > | |
1019 :put ='path' . \",/test\" | |
1020 < If there is no expression after '=', Vim uses the | |
1021 previous expression. You can see it with ":dis =". | |
1022 | |
1023 :[line]pu[t]! [x] Put the text [from register x] before [line] (default | |
1024 current line). | |
1025 | |
1026 ["x]]p or *]p* *]<MiddleMouse>* | |
1027 ["x]]<MiddleMouse> Like "p", but adjust the indent to the current line. | |

1035 Using the mouse only works when 'mouse' contains 'n' | |
1036 or 'a'. {not in Vi} | |
1037 | |
1038 You can use these commands to copy text from one place to another. Do this | |
1039 by first getting the text into a register with a yank, delete or change | |
1040 command, then inserting the register contents with a put command. You can | |
1041 also use these commands to move text from one file to another, because Vim | |
1042 preserves all registers when changing buffers (the CTRL-^ command is a quick | |
1043 way to toggle between two files). | |
1044 | |
1045 *linewise-register* *characterwise-register* | |
1046 You can repeat the put commands with "." (except for :put) and undo them. If | |
1047 the command that was used to get the text into the register was |linewise|, | |
1048 Vim inserts the text below ("p") or above ("P") the line where the cursor is. | |
1049 Otherwise Vim inserts the text after ("p") or before ("P") the cursor. With | |
1050 the ":put" command, Vim always inserts the text in the next line. You can | |
1051 exchange two characters with the command sequence "xp". You can exchange two | |
1052 lines with the command sequence "ddp". You can exchange two words with the | |
1053 command sequence "deep" (start with the cursor in the blank space before the | |
1054 first word). You can use the "']" or "`]" command after the put command to | |
1055 move the cursor to the end of the inserted text, or use "'[" or "`[" to move | |
1056 the cursor to the start. | |
1057 | |
1058 *put-Visual-mode* *v_p* *v_P* | |
1059 When using a put command like |p| or |P| in Visual mode, Vim will try to | |
1060 replace the selected text with the contents of the register. Whether this | |
1061 works well depends on the type of selection and the type of the text in the | |
1062 register. With blockwise selection it also depends on the size of the block | |
236 | 1063 and whether the corners are on an existing character. (Implementation detail: |
7 | 1064 it actually works by first putting the register after the selection and then |
236 | 1065 deleting the selection.) |

1070 unnamed register will be changed each time. |
7 | 1071 |
1072 *blockwise-register* | |
1073 If you use a blockwise Visual mode command to get the text into the register, | |
1074 the block of text will be inserted before ("P") or after ("p") the cursor | |
1075 column in the current and next lines. Vim makes the whole block of text start | |
1076 in the same column. Thus the inserted text looks the same as when it was | |
1077 yanked or deleted. Vim may replace some <Tab> characters with spaces to make | |
1078 this happen. However, if the width of the block is not a multiple of a <Tab> | |
1079 width and the text after the inserted block contains <Tab>s, that text may be | |
1080 misaligned. | |
1081 | |
1082 Note that after a characterwise yank command, Vim leaves the cursor on the | |
1083 first yanked character that is closest to the start of the buffer. This means | |
1084 that "yl" doesn't move the cursor, but "yh" moves the cursor one character | |
1085 left. | |
1086 Rationale: In Vi the "y" command followed by a backwards motion would | |
1087 sometimes not move the cursor to the first yanked character, | |
1088 because redisplaying was skipped. In Vim it always moves to | |
1089 the first character, as specified by Posix. | |
1090 With a linewise yank command the cursor is put in the first line, but the | |
1091 column is unmodified, thus it may not be on the first yanked character. | |
1092 | |
1093 There are nine types of registers: *registers* *E354* | |
1094 1. The unnamed register "" | |
1095 2. 10 numbered registers "0 to "9 | |
1096 3. The small delete register "- | |
1097 4. 26 named registers "a to "z or "A to "Z | |
1098 5. four read-only registers ":, "., "% and "# | |
1099 6. the expression register "= | |
1100 7. The selection and drop registers "*, "+ and "~ | |
1101 8. The black hole register "_ | |
1102 9. Last search pattern register "/ | |
1103 | |
1104 1. Unnamed register "" *quote_quote* *quotequote* | |
1105 Vim fills this register with text deleted with the "d", "c", "s", "x" commands | |
1106 or copied with the yank "y" command, regardless of whether or not a specific | |
8 | 1107 register was used (e.g. "xdd). This is like the unnamed register is pointing |

1111 register. |
42 | 1112 Vim uses the contents of the unnamed register for any put command (p or P) |
1113 which does not specify a register. Additionally you can access it with the | |
1114 name '"'. This means you have to type two double quotes. Writing to the "" | |
1115 register writes to register "0. | |
7 | 1116 {Vi: register contents are lost when changing files, no '"'} |
1117 | |
1118 2. Numbered registers "0 to "9 *quote_number* *quote0* *quote1* | |
1119 *quote2* *quote3* *quote4* *quote9* | |
1120 Vim fills these registers with text from yank and delete commands. | |
1121 Numbered register 0 contains the text from the most recent yank command, | |
1122 unless the command specified another register with ["x]. | |
1123 Numbered register 1 contains the text deleted by the most recent delete or | |
1124 change command, unless the command specified another register or the text is | |
1125 less than one line (the small delete register is used then). An exception is | |
42 | 1126 made for the delete operator with these movement commands: |%|, |(|, |)|, |`|, |
1127 |/|, |?|, |n|, |N|, |{| and |}|. Register "1 is always used then (this is Vi | |
1128 compatible). The "- register is used as well if the delete is within a line. | |
7 | 1129 With each successive deletion or change, Vim shifts the previous contents |
1130 of register 1 into register 2, 2 into 3, and so forth, losing the previous | |
1131 contents of register 9. | |
1132 {Vi: numbered register contents are lost when changing files; register 0 does | |
1133 not exist} | |
1134 | |
1135 3. Small delete register "- *quote_-* *quote-* | |
1136 This register contains text from commands that delete less than one line, | |
1137 except when the command specifies a register with ["x]. | |
1138 {not in Vi} | |
1139 | |
1140 4. Named registers "a to "z or "A to "Z *quote_alpha* *quotea* | |
1141 Vim fills these registers only when you say so. Specify them as lowercase | |
1142 letters to replace their previous contents or as uppercase letters to append | |
164 | 1143 to their previous contents. When the '>' flag is present in 'cpoptions' then |
1144 a line break is inserted before the appended text. | |
7 | 1145 |
1146 5. Read-only registers ":, "., "% and "# | |
1147 These are '%', '#', ':' and '.'. You can use them only with the "p", "P", | |
1148 and ":put" commands and with CTRL-R. {not in Vi} | |
1149 *quote_.* *quote.* *E29* | |
1150 ". Contains the last inserted text (the same as what is inserted | |
1151 with the insert mode commands CTRL-A and CTRL-@). Note: this | |
1152 doesn't work with CTRL-R on the command-line. It works a bit | |
1153 differently, like inserting the text instead of putting it | |
1154 ('textwidth' and other options affect what is inserted). | |
1155 *quote_%* *quote%* | |
1156 "% Contains the name of the current file. | |
1157 *quote_#* *quote#* | |
1158 "# Contains the name of the alternate file. | |
1159 *quote_:* *quote:* *E30* | |
1160 ": Contains the most recent executed command-line. Example: Use | |
1161 "@:" to repeat the previous command-line command. | |
1162 The command-line is only stored in this register when at least | |
1163 one character of it was typed. Thus it remains unchanged if | |
1164 the command was completely from a mapping. | |

7 | 1169 This is not really a register that stores text, but is a way to use an |
1170 expression in commands which use a register. The expression register is | |
1171 read-only; you cannot put text into it. After the '=', the cursor moves to | |
1172 the command-line, where you can enter any expression (see |expression|). All | |
1173 normal command-line editing commands are available, including a special | |
1174 history for expressions. When you end the command-line by typing <CR>, Vim | |
1175 computes the result of the expression. If you end it with <Esc>, Vim abandons | |
1176 the expression. If you do not enter an expression, Vim uses the previous | |

1190 Use these registers for storing and retrieving the selected text for the GUI. |
7 | 1191 See |quotestar| and |quoteplus|. When the clipboard is not available or not |
571 | 1192 working, the unnamed register is used instead. For Unix systems the clipboard |
1193 is only available when the |+xterm_clipboard| feature is present. {not in Vi} | |
7 | 1194 |
1195 Note that there is only a distinction between "* and "+ for X11 systems. For | |
1196 an explanation of the difference, see |x11-selection|. Under MS-Windows, use | |
1197 of "* and "+ is actually synonymous and refers to the |gui-clipboard|. | |
1198 | |
1199 *quote_~* *quote~* *<Drop>* | |
1200 The read-only "~ register stores the dropped text from the last drag'n'drop | |
1201 operation. When something has been dropped onto Vim, the "~ register is | |
1202 filled in and the <Drop> pseudo key is sent for notification. You can remap | |
1203 this key if you want; the default action (for all modes) is to insert the | |
1204 contents of the "~ register at the cursor position. {not in Vi} | |
9 | 1205 {only available when compiled with the |+dnd| feature, currently only with the |
7 | 1206 GTK GUI} |
1207 | |
1208 Note: The "~ register is only used when dropping plain text onto Vim. | |
1209 Drag'n'drop of URI lists is handled internally. | |
1210 | |
1211 8. Black hole register "_ *quote_* | |
1212 When writing to this register, nothing happens. This can be used to delete | |
1213 text without affecting the normal registers. When reading from this register, | |
1214 nothing is returned. {not in Vi} | |
1215 | |
1216 9. Last search pattern register "/ *quote_/* *quote/* | |
1217 Contains the most recent search-pattern. This is used for "n" and 'hlsearch'. | |
3492 | 1218 It is writable with `:let`, you can change it to have 'hlsearch' highlight |
7 | 1219 other matches without actually searching. You can't yank or delete into this |
1621 | 1220 register. The search direction is available in |v:searchforward|. |
1221 Note that the valued is restored when returning from a function | |
1222 |function-search-undo|. | |
1223 {not in Vi} | |
7 | 1224 |
1225 *@/* | |
3492 | 1226 You can write to a register with a `:let` command |:let-@|. Example: > |
7 | 1227 :let @/ = "the" |
1228 | |
1229 If you use a put command without specifying a register, Vim uses the register | |
1230 that was last filled (this is also the contents of the unnamed register). If | |
3492 | 1231 you are confused, use the `:dis` command to find out what Vim will put (this |
7 | 1232 command displays all named and numbered registers; the unnamed register is |
1233 labelled '"'). | |
1234 | |
1235 The next three commands always work on whole lines. | |
1236 | |
1237 :[range]co[py] {address} *:co* *:copy* | |
1238 Copy the lines given by [range] to below the line | |

1254 {not in Vi} | |
1255 Not available when |+ex_extra| feature was disabled at | |

1257 | |
1258 :[range]ri[ght] [width] *:ri* *:right* | |
1259 Right-align lines in [range] at [width] columns | |
1260 (default 'textwidth' or 80 when 'textwidth' is 0). | |
1261 {not in Vi} | |
1262 Not available when |+ex_extra| feature was disabled at | |
1263 compile time. | |
1264 | |
1265 *:le* *:left* | |
1266 :[range]le[ft] [indent] | |
1267 Left-align lines in [range]. Sets the indent in the | |
1268 lines to [indent] (default 0). {not in Vi} | |
1269 Not available when |+ex_extra| feature was disabled at | |
1270 compile time. | |
1271 | |
1272 *gq* | |
216 | 1273 gq{motion} Format the lines that {motion} moves over. |
667 | 1274 Formatting is done with one of three methods: |
1275 1. If 'formatexpr' is not empty the expression is | |
1276 evaluated. This can differ for each buffer. | |
670 | 1277 2. If 'formatprg' is not empty an external program |
667 | 1278 is used. |
843 | 1279 3. Otherwise formatting is done internally. |
667 | 1280 |
1281 In the third case the 'textwidth' option controls the | |
1282 length of each formatted line (see below). | |
216 | 1283 If the 'textwidth' option is 0, the formatted line |
1284 length is the screen width (with a maximum width of | |
667 | 1285 79). |
7 | 1286 The 'formatoptions' option controls the type of |
1287 formatting |fo-table|. | |
216 | 1288 The cursor is left on the first non-blank of the last |
1289 formatted line. | |
7 | 1290 NOTE: The "Q" command formerly performed this |
1291 function. If you still want to use "Q" for | |
1292 formatting, use this mapping: > | |
1293 :nnoremap Q gq | |

1299 *v_gq* | |
1300 {Visual}gq Format the highlighted text. (for {Visual} see | |
1301 |Visual-mode|). {not in Vi} | |
1302 | |
1303 *gw* | |
1304 gw{motion} Format the lines that {motion} moves over. Similar to | |
1305 |gq| but puts the cursor back at the same position in | |
667 | 1306 the text. However, 'formatprg' and 'formatexpr' are |
1307 not used. {not in Vi} | |
7 | 1308 |
9 | 1309 gwgw *gwgw* *gww* |
1310 gww Format the current line as with "gw". {not in Vi} | |
1311 | |
1312 *v_gw* | |
1313 {Visual}gw Format the highlighted text as with "gw". (for | |
1314 {Visual} see |Visual-mode|). {not in Vi} | |
1315 | |
7 | 1316 Example: To format the current paragraph use: *gqap* > |
1317 gqap | |
1318 | |
1319 The "gq" command leaves the cursor in the line where the motion command takes | |
1320 the cursor. This allows you to repeat formatting repeated with ".". This | |
1321 works well with "gqj" (format current and next line) and "gq}" (format until | |
1322 end of paragraph). Note: When 'formatprg' is set, "gq" leaves the cursor on | |
1323 the first formatted line (as with using a filter command). | |
1324 | |
1325 If you want to format the current paragraph and continue where you were, use: > | |
1326 gwap | |
1327 If you always want to keep paragraphs formatted you may want to add the 'a' | |
1328 flag to 'formatoptions'. See |auto-format|. | |
1329 | |
1330 If the 'autoindent' option is on, Vim uses the indent of the first line for | |
1331 the following lines. | |
1332 | |
1333 Formatting does not change empty lines (but it does change lines with only | |
1334 white space!). | |
1335 | |
1336 The 'joinspaces' option is used when lines are joined together. | |
1337 | |
667 | 1338 You can set the 'formatexpr' option to an expression or the 'formatprg' option |
1339 to the name of an external program for Vim to use for text formatting. The | |
1340 'textwidth' and other options have no effect on formatting by an external | |
1341 program. | |
7 | 1342 |
1343 *right-justify* | |
1344 There is no command in Vim to right justify text. You can do it with | |
1345 an external command, like "par" (e.g.: "!}par" to format until the end of the | |
1346 paragraph) or set 'formatprg' to "par". | |
1347 | |
1348 *format-comments* | |
1621 | 1349 An overview of comment formatting is in section |30.6| of the user manual. |
1350 | |
1351 Vim can automatically insert and format comments in a special way. Vim | |
1352 recognizes a comment by a specific string at the start of the line (ignoring | |
1353 white space). Three types of comments can be used: | |
7 | 1354 |
1355 - A comment string that repeats at the start of each line. An example is the | |
1356 type of comment used in shell scripts, starting with "#". | |
1357 - A comment string that occurs only in the first line, not in the following | |
1358 lines. An example is this list with dashes. | |
1359 - Three-piece comments that have a start string, an end string, and optional | |
1360 lines in between. The strings for the start, middle and end are different. | |
1621 | 1361 An example is the C style comment: |
7 | 1362 /* |
1363 * this is a C comment | |
1364 */ | |
1365 | |
1366 The 'comments' option is a comma-separated list of parts. Each part defines a | |
1367 type of comment string. A part consists of: | |
1368 {flags}:{string} | |
1369 | |
1370 {string} is the literal text that must appear. | |
1371 | |
1372 {flags}: | |
1373 n Nested comment. Nesting with mixed parts is allowed. If 'comments' | |
1374 is "n:),n:>" a line starting with "> ) >" is a comment. | |
1375 | |
1376 b Blank (<Space>, <Tab> or <EOL>) required after {string}. | |
1377 | |
1378 f Only the first line has the comment string. Do not repeat comment on | |
1379 the next line, but preserve indentation (e.g., a bullet-list). | |
1380 | |
1381 s Start of three-piece comment | |
1382 | |
1383 m Middle of a three-piece comment | |
1384 | |
1385 e End of a three-piece comment | |
1386 | |
1621 | 1387 l Left align. Used together with 's' or 'e', the leftmost character of |
1388 start or end will line up with the leftmost character from the middle. | |
1389 This is the default and can be omitted. See below for more details. | |
7 | 1390 |
1621 | 1391 r Right align. Same as above but rightmost instead of leftmost. See |
1392 below for more details. | |
7 | 1393 |
1621 | 1394 O Don't consider this comment for the "O" command. |
7 | 1395 |
1396 x Allows three-piece comments to be ended by just typing the last | |
1621 | 1397 character of the end-comment string as the first action on a new |
1398 line when the middle-comment string has been inserted automatically. | |
1399 See below for more details. | |
7 | 1400 |
1401 {digits} | |
1621 | 1402 When together with 's' or 'e': add {digit} amount of offset to an |
1403 automatically inserted middle or end comment leader. The offset begins | |
1404 from a left alignment. See below for more details. | |
7 | 1405 |
1406 -{digits} | |
1407 Like {digits} but reduce the indent. This only works when there is | |
1408 some indent for the start or end part that can be removed. | |
1409 | |
1410 When a string has none of the 'f', 's', 'm' or 'e' flags, Vim assumes the | |
1411 comment string repeats at the start of each line. The flags field may be | |
1412 empty. | |
1413 | |
1414 Any blank space in the text before and after the {string} is part of the | |
1415 {string}, so do not include leading or trailing blanks unless the blanks are a | |
1416 required part of the comment string. | |
1417 | |
1418 When one comment leader is part of another, specify the part after the whole. | |
1419 For example, to include both "-" and "->", use > | |
1420 :set comments=f:->,f:- | |
1421 | |
1422 A three-piece comment must always be given as start,middle,end, with no other | |
1423 parts in between. An example of a three-piece comment is > | |
1424 sr:/*,mb:*,ex:*/ | |
1425 for C-comments. To avoid recognizing "*ptr" as a comment, the middle string | |
1426 includes the 'b' flag. For three-piece comments, Vim checks the text after | |
1427 the start and middle strings for the end string. If Vim finds the end string, | |
1428 the comment does not continue on the next line. Three-piece comments must | |
1429 have a middle string because otherwise Vim can't recognize the middle lines. | |
1430 | |
1431 Notice the use of the "x" flag in the above three-piece comment definition. | |
1432 When you hit Return in a C-comment, Vim will insert the middle comment leader | |
1621 | 1433 for the new line: " * ". To close this comment you just have to type "/" |
7 | 1434 before typing anything else on the new line. This will replace the |
1621 | 1435 middle-comment leader with the end-comment leader and apply any specified |
1436 alignment, leaving just " */". There is no need to hit BackSpace first. | |
1437 | |
2826 | 1438 When there is a match with a middle part, but there also is a maching end part |
1439 which is longer, the end part is used. This makes a C style comment work | |
1440 without requiring the middle part to end with a space. | |
1621 | 1441 |
1442 Here is an example of alignment flags at work to make a comment stand out | |
2826 | 1443 (kind of looks like a 1 too). Consider comment string: > |
1444 :set comments=sr:/***,m:**,ex-2:******/ | |
1445 < | |
1446 /*** ~ | |
1447 **<--right aligned from "r" flag ~ | |
1448 ** ~ | |
1449 offset 2 spaces for the "-2" flag--->** ~ | |
1450 ******/ ~ | |
1621 | 1451 In this case, the first comment was typed, then return was pressed 4 times, |
1452 then "/" was pressed to end the comment. | |
7 | 1453 |
1621 | 1454 Here are some finer points of three part comments. There are three times when |
1455 alignment and offset flags are taken into consideration: opening a new line | |
1456 after a start-comment, opening a new line before an end-comment, and | |
1457 automatically ending a three-piece comment. The end alignment flag has a | |
1458 backwards perspective; the result is that the same alignment flag used with | |
1459 "s" and "e" will result in the same indent for the starting and ending pieces. | |
1460 Only one alignment per comment part is meant to be used, but an offset number | |
1461 will override the "r" and "l" flag. | |
1462 | |
1463 Enabling 'cindent' will override the alignment flags in many cases. | |
1464 Reindenting using a different method like |gq| or |=| will not consult | |
1465 alignment flags either. The same behaviour can be defined in those other | |
1466 formatting options. One consideration is that 'cindent' has additional options | |
1467 for context based indenting of comments but cannot replicate many three piece | |
2826 | 1468 indent alignments. However, 'indentexpr' has the ability to work better with |
1469 three piece comments. | |
1621 | 1470 |
1471 Other examples: > | |
7 | 1472 "b:*" Includes lines starting with "*", but not if the "*" is |
1473 followed by a non-blank. This avoids a pointer dereference | |
1474 like "*str" to be recognized as a comment. | |
1475 "n:>" Includes a line starting with ">", ">>", ">>>", etc. | |
1476 "fb:-" Format a list that starts with "- ". | |
1477 | |
1478 By default, "b:#" is included. This means that a line that starts with | |
1479 "#include" is not recognized as a comment line. But a line that starts with | |
1480 "# define" is recognized. This is a compromise. | |
1481 | |
1482 {not available when compiled without the |+comments| feature} | |
1483 | |
1484 *fo-table* | |
1485 You can use the 'formatoptions' option to influence how Vim formats text. | |
1486 'formatoptions' is a string that can contain any of the letters below. The | |
1487 default setting is "tcq". You can separate the option letters with commas for | |
1488 readability. | |
1489 | |
1490 letter meaning when present in 'formatoptions' ~ | |
1491 | |
1121 | 1492 t Auto-wrap text using textwidth |
7 | 1493 c Auto-wrap comments using textwidth, inserting the current comment |
1494 leader automatically. | |
1495 r Automatically insert the current comment leader after hitting | |
1496 <Enter> in Insert mode. | |
1497 o Automatically insert the current comment leader after hitting 'o' or | |
1498 'O' in Normal mode. | |
1499 q Allow formatting of comments with "gq". | |
1500 Note that formatting will not change blank lines or lines containing | |
1501 only the comment leader. A new paragraph starts after such a line, | |
1502 or when the comment leader changes. | |
1503 w Trailing white space indicates a paragraph continues in the next line. | |
1504 A line that ends in a non-white character ends a paragraph. | |
1505 a Automatic formatting of paragraphs. Every time text is inserted or | |
1506 deleted the paragraph will be reformatted. See |auto-format|. | |
1507 When the 'c' flag is present this only happens for recognized | |
1508 comments. | |
41 | 1509 n When formatting text, recognize numbered lists. This actually uses |
1510 the 'formatlistpat' option, thus any kind of list can be used. The | |
1511 indent of the text after the number is used for the next line. The | |
1621 | 1512 default is to find a number, optionally followed by '.', ':', ')', |
41 | 1513 ']' or '}'. Note that 'autoindent' must be set too. Doesn't work |
1514 well together with "2". | |
7 | 1515 Example: > |
1516 1. the first item | |
1517 wraps | |
1518 2. the second item | |
1519 2 When formatting text, use the indent of the second line of a paragraph | |
1520 for the rest of the paragraph, instead of the indent of the first | |
1521 line. This supports paragraphs in which the first line has a | |
1522 different indent than the rest. Note that 'autoindent' must be set | |
1523 too. Example: > | |
1524 first line of a paragraph | |
1525 second line of the same paragraph | |
1526 third line. | |
3682 | 1527 < This also works inside comments, ignoring the comment leader. |
7 | 1528 v Vi-compatible auto-wrapping in insert mode: Only break a line at a |
1529 blank that you have entered during the current insert command. (Note: | |
1530 this is not 100% Vi compatible. Vi has some "unexpected features" or | |
1531 bugs in this area. It uses the screen column instead of the line | |
1532 column.) | |
1533 b Like 'v', but only auto-wrap if you enter a blank at or before | |
1534 the wrap margin. If the line was longer than 'textwidth' when you | |
1535 started the insert, or you do not enter a blank in the insert before | |
1536 reaching 'textwidth', Vim does not perform auto-wrapping. | |
1537 l Long lines are not broken in insert mode: When a line was longer than | |
1538 'textwidth' when the insert command started, Vim does not | |
1539 automatically format it. | |
1540 m Also break at a multi-byte character above 255. This is useful for | |
1541 Asian text where every character is a word on its own. | |
1542 M When joining lines, don't insert a space before or after a multi-byte | |
1543 character. Overrules the 'B' flag. | |
1544 B When joining lines, don't insert a space between two multi-byte | |
1545 characters. Overruled by the 'M' flag. | |
1546 1 Don't break a line after a one-letter word. It's broken before it | |
1547 instead (if possible). | |
3562 | 1548 j Where it makes sense, remove a comment leader when joining lines. For |
1549 example, joining: | |
1550 int i; // the index ~ | |
1551 // in the list ~ | |
1552 Becomes: | |
1553 int i; // the index in the list ~ | |
7 | 1554 |
1555 | |
1556 With 't' and 'c' you can specify when Vim performs auto-wrapping: | |
1557 value action ~ | |
1558 "" no automatic formatting (you can use "gq" for manual formatting) | |
1559 "t" automatic formatting of text, but not comments | |
1560 "c" automatic formatting for comments, but not text (good for C code) | |
1561 "tc" automatic formatting for text and comments | |
1562 | |
867 | 1563 Note that when 'textwidth' is 0, Vim does no automatic formatting anyway (but |
1564 does insert comment leaders according to the 'comments' option). An exception | |
1565 is when the 'a' flag is present. |auto-format| | |
7 | 1566 |
1567 Note that when 'paste' is on, Vim does no formatting at all. | |
1568 | |
1569 Note that 'textwidth' can be non-zero even if Vim never performs auto-wrapping; | |
1570 'textwidth' is still useful for formatting with "gq". | |
1571 | |
1572 If the 'comments' option includes "/*", "*" and/or "*/", then Vim has some | |
1573 built in stuff to treat these types of comments a bit more cleverly. | |
1574 Opening a new line before or after "/*" or "*/" (with 'r' or 'o' present in | |
1575 'formatoptions') gives the correct start of the line automatically. The same | |
236 | 1576 happens with formatting and auto-wrapping. Opening a line after a line |
7 | 1577 starting with "/*" or "*" and containing "*/", will cause no comment leader to |
1578 be inserted, and the indent of the new line is taken from the line containing | |
1579 the start of the comment. | |
1580 E.g.: | |
1581 /* ~ | |
1582 * Your typical comment. ~ | |
1583 */ ~ | |
1584 The indent on this line is the same as the start of the above | |
1585 comment. | |
1586 | |
1587 All of this should be really cool, especially in conjunction with the new | |
1588 :autocmd command to prepare different settings for different types of file. | |
1589 | |
1590 Some examples: | |
1591 for C code (only format comments): > | |
1592 :set fo=croq | |
1593 < for Mail/news (format all, don't start comment with "o" command): > | |
1594 :set fo=tcrq | |
1595 < | |
1596 | |
3492 | 1597 Automatic formatting *auto-format* *autoformat* |
7 | 1598 |
1599 When the 'a' flag is present in 'formatoptions' text is formatted | |
1600 automatically when inserting text or deleting text. This works nice for | |
1601 editing text paragraphs. A few hints on how to use this: | |
1602 | |
1603 - You need to properly define paragraphs. The simplest is paragraphs that are | |
1604 separated by a blank line. When there is no separating blank line, consider | |
1605 using the 'w' flag and adding a space at the end of each line in the | |
1606 paragraphs except the last one. | |
1607 | |
1608 - You can set the 'formatoptions' based on the type of file |filetype| or | |
1609 specifically for one file with a |modeline|. | |
1610 | |
1611 - Set 'formatoptions' to "aw2tq" to make text with indents like this: | |
1612 | |
1613 bla bla foobar bla | |
1614 bla foobar bla foobar bla | |
1615 bla bla foobar bla | |
1616 bla foobar bla bla foobar | |
1617 | |
1618 - Add the 'c' flag to only auto-format comments. Useful in source code. | |
1619 | |
867 | 1620 - Set 'textwidth' to the desired width. If it is zero then 79 is used, or the |
1621 width of the screen if this is smaller. | |
1622 | |
7 | 1623 And a few warnings: |
1624 | |
1625 - When part of the text is not properly separated in paragraphs, making | |
1626 changes in this text will cause it to be formatted anyway. Consider doing > | |
1627 | |
1628 :set fo-=a | |
1629 | |
1630 - When using the 'w' flag (trailing space means paragraph continues) and | |
1631 deleting the last line of a paragraph with |dd|, the paragraph will be | |
1632 joined with the next one. | |
1633 | |
1634 - Changed text is saved for undo. Formatting is also a change. Thus each | |
1635 format action saves text for undo. This may consume quite a lot of memory. | |
1636 | |
1637 - Formatting a long paragraph and/or with complicated indenting may be slow. | |
1638 | |

1640 7. Sorting text *sorting* | |
1641 | |
1642 Vim has a sorting function and a sorting command. The sorting function can be | |
1643 found here: |sort()|. | |
1644 | |
1645 *:sor* *:sort* | |
826 | 1646 :[range]sor[t][!] [i][u][r][n][x][o] [/{pattern}/] |
586 | 1647 Sort lines in [range]. When no range is given all |
1648 lines are sorted. | |
282 | 1649 |
1650 With [!] the order is reversed. | |
1651 | |
1652 With [i] case is ignored. | |
1653 | |
293 | 1654 With [n] sorting is done on the first decimal number |
826 | 1655 in the line (after or inside a {pattern} match). |
1698 | 1656 One leading '-' is included in the number. |
293 | 1657 |
1658 With [x] sorting is done on the first hexadecimal | |
826 | 1659 number in the line (after or inside a {pattern} |
1660 match). A leading "0x" or "0X" is ignored. | |
1698 | 1661 One leading '-' is included in the number. |
293 | 1662 |
1663 With [o] sorting is done on the first octal number in | |
826 | 1664 the line (after or inside a {pattern} match). |
293 | 1665 |
282 | 1666 With [u] only keep the first of a sequence of |
1667 identical lines (ignoring case when [i] is used). | |
826 | 1668 Without this flag, a sequence of identical lines |
1669 will be kept in their original order. | |
293 | 1670 Note that leading and trailing white space may cause |
1671 lines to be different. | |
282 | 1672 |
826 | 1673 When /{pattern}/ is specified and there is no [r] flag |
1674 the text matched with {pattern} is skipped, so that | |
1675 you sort on what comes after the match. | |
282 | 1676 Instead of the slash any non-letter can be used. |
1677 For example, to sort on the second comma-separated | |
1678 field: > | |
1679 :sort /[^,]*,/ | |
1680 < To sort on the text at virtual column 10 (thus | |
1681 ignoring the difference between tabs and spaces): > | |
1682 :sort /.*\%10v/ | |
824 | 1683 < To sort on the first number in the line, no matter |
1684 what is in front of it: > | |
1621 | 1685 :sort /.\{-}\ze\d/ |
1686 < (Explanation: ".\{-}" matches any text, "\ze" sets the | |
1687 end of the match and \d matches a digit.) | |
1688 With [r] sorting is done on the matching {pattern} | |
826 | 1689 instead of skipping past it as described above. |
1690 For example, to sort on only the first three letters | |
1691 of each line: > | |
1692 :sort /\a\a\a/ r | |
1693 | |
1694 < If a {pattern} is used, any lines which don't have a | |
1695 match for {pattern} are kept in their current order, | |
1696 but separate from the lines which do match {pattern}. | |
1697 If you sorted in reverse, they will be in reverse | |
1698 order after the sorted lines, otherwise they will be | |
1699 in their original order, right before the sorted | |
1700 lines. | |
1701 | |
1314 | 1702 If {pattern} is empty (e.g. // is specified), the |
1703 last search pattern is used. This allows trying out | |
1704 a pattern first. | |
1705 | |
3492 | 1706 Note that using `:sort` with `:global` doesn't sort the matching lines, it's |
293 | 1707 quite useless. |
7 | 1708 |
359 | 1709 The details about sorting depend on the library function used. There is no |
1710 guarantee that sorting is "stable" or obeys the current locale. You will have | |
1711 to try it out. | |
1712 | |
826 | 1713 The sorting can be interrupted, but if you interrupt it too late in the |
1714 process you may end up with duplicated lines. This also depends on the system | |
1715 library function used. | |
