| 8 Text hardly ever comes in one sentence per line. This chapter is about | |
| 9 breaking sentences to make them fit on a page and other formatting. | |
| 10 Vim also has useful features for editing single-line paragraphs and tables. | |

| 22 ============================================================================== | |
| 23 *25.1* Breaking lines | |
| 24 | |
| 25 Vim has a number of functions that make dealing with text easier. By default, | |
| 26 the editor does not perform automatic line breaks. In other words, you have | |
| 27 to press <Enter> yourself. This is useful when you are writing programs where | |
| 28 you want to decide where the line ends. It is not so good when you are | |
| 29 creating documentation and want the text to be at most 70 character wide. | |
| 30 If you set the 'textwidth' option, Vim automatically inserts line breaks. | |
| 31 Suppose, for example, that you want a very narrow column of only 30 | |
| 32 characters. You need to execute the following command: > | |
| 33 | |
| 34 :set textwidth=30 | |
| 35 | |
| 36 Now you start typing (ruler added): | |
| 37 | |
| 38 1 2 3 | |
| 39 12345678901234567890123456789012345 | |
| 40 I taught programming for a whi ~ | |
| 41 | |
| 42 If you type "l" next, this makes the line longer than the 30-character limit. | |
| 43 When Vim sees this, it inserts a line break and you get the following: | |
| 44 | |
| 45 1 2 3 | |
| 46 12345678901234567890123456789012345 | |
| 47 I taught programming for a ~ | |
| 48 whil ~ | |
| 49 | |
| 50 Continuing on, you can type in the rest of the paragraph: | |
| 51 | |
| 52 1 2 3 | |
| 53 12345678901234567890123456789012345 | |
| 54 I taught programming for a ~ | |
| 55 while. One time, I was stopped ~ | |
| 56 by the Fort Worth police, ~ | |
| 57 because my homework was too ~ | |
| 58 hard. True story. ~ | |
| 59 | |
| 60 You do not have to type newlines; Vim puts them in automatically. | |
| 61 | |
| 62 Note: | |
| 63 The 'wrap' option makes Vim display lines with a line break, but this | |
| 64 doesn't insert a line break in the file. | |
| 65 | |
| 66 | |
| 67 REFORMATTING | |
| 68 | |
| 69 The Vim editor is not a word processor. In a word processor, if you delete | |
| 70 something at the beginning of the paragraph, the line breaks are reworked. In | |
| 71 Vim they are not; so if you delete the word "programming" from the first line, | |
| 72 all you get is a short line: | |
| 73 | |
| 74 1 2 3 | |
| 75 12345678901234567890123456789012345 | |
| 76 I taught for a ~ | |
| 77 while. One time, I was stopped ~ | |
| 78 by the Fort Worth police, ~ | |
| 79 because my homework was too ~ | |
| 80 hard. True story. ~ | |
| 81 | |
| 82 This does not look good. To get the paragraph into shape you use the "gq" | |
| 83 operator. | |
| 84 Let's first use this with a Visual selection. Starting from the first | |
| 85 line, type: > | |
| 86 | |
| 87 v4jgq | |
| 88 | |
| 5400 | 89 "v" to start Visual mode, "4j" to move to the end of the paragraph and then |
| 7 | 90 the "gq" operator. The result is: |
| 91 | |
| 92 1 2 3 | |
| 93 12345678901234567890123456789012345 | |
| 94 I taught for a while. One ~ | |
| 95 time, I was stopped by the ~ | |
| 96 Fort Worth police, because my ~ | |
| 97 homework was too hard. True ~ | |
| 98 story. ~ | |
| 99 | |
| 100 Note: there is a way to do automatic formatting for specific types of text | |
| 101 layouts, see |auto-format|. | |
| 102 | |
| 103 Since "gq" is an operator, you can use one of the three ways to select the | |
| 104 text it works on: With Visual mode, with a movement and with a text object. | |
| 105 The example above could also be done with "gq4j". That's less typing, but | |
| 106 you have to know the line count. A more useful motion command is "}". This | |
| 107 moves to the end of a paragraph. Thus "gq}" formats from the cursor to the | |
| 108 end of the current paragraph. | |
| 109 A very useful text object to use with "gq" is the paragraph. Try this: > | |
| 110 | |
| 111 gqap | |
| 112 | |
| 113 "ap" stands for "a-paragraph". This formats the text of one paragraph | |
| 114 (separated by empty lines). Also the part before the cursor. | |
| 115 If you have your paragraphs separated by empty lines, you can format the | |
| 116 whole file by typing this: > | |
| 117 | |
| 118 gggqG | |
| 119 | |
| 120 "gg" to move to the first line, "gqG" to format until the last line. | |
| 121 Warning: If your paragraphs are not properly separated, they will be joined | |
| 1256 | 122 together. A common mistake is to have a line with a space or tab. That's a |
| 7 | 123 blank line, but not an empty line. |
| 124 | |
| 1121 | 125 Vim is able to format more than just plain text. See |fo-table| for how to |
| 7 | 126 change this. See the 'joinspaces' option to change the number of spaces used |
| 127 after a full stop. | |
| 128 It is possible to use an external program for formatting. This is useful | |
| 129 if your text can't be properly formatted with Vim's builtin command. See the | |
| 130 'formatprg' option. | |
| 131 | |
| 132 ============================================================================== | |
| 133 *25.2* Aligning text | |
| 134 | |
| 135 To center a range of lines, use the following command: > | |
| 136 | |
| 137 :{range}center [width] | |
| 138 | |
| 139 {range} is the usual command-line range. [width] is an optional line width to | |
| 140 use for centering. If [width] is not specified, it defaults to the value of | |
| 141 'textwidth'. (If 'textwidth' is 0, the default is 80.) | |
| 142 For example: > | |
| 143 | |
| 144 :1,5center 40 | |
| 145 | |
| 146 results in the following: | |
| 147 | |
| 148 I taught for a while. One ~ | |
| 149 time, I was stopped by the ~ | |
| 150 Fort Worth police, because my ~ | |
| 151 homework was too hard. True ~ | |
| 152 story. ~ | |
| 153 | |
| 154 | |
| 155 RIGHT ALIGNMENT | |
| 156 | |
| 157 Similarly, the ":right" command right-justifies the text: > | |
| 158 | |
| 159 :1,5right 37 | |
| 160 | |
| 161 gives this result: | |
| 162 | |
| 163 I taught for a while. One ~ | |
| 164 time, I was stopped by the ~ | |
| 165 Fort Worth police, because my ~ | |
| 166 homework was too hard. True ~ | |
| 167 story. ~ | |
| 168 | |
| 169 LEFT ALIGNMENT | |
| 170 | |
| 171 Finally there is this command: > | |
| 172 | |
| 173 :{range}left [margin] | |
| 174 | |
| 175 Unlike ":center" and ":right", however, the argument to ":left" is not the | |
| 176 length of the line. Instead it is the left margin. If it is omitted, the | |
| 177 text will be put against the left side of the screen (using a zero margin | |
| 178 would do the same). If it is 5, the text will be indented 5 spaces. For | |
| 179 example, use these commands: > | |
| 180 | |
| 181 :1left 5 | |
| 182 :2,5left | |
| 183 | |
| 184 This results in the following: | |
| 185 | |
| 186 I taught for a while. One ~ | |
| 187 time, I was stopped by the ~ | |
| 188 Fort Worth police, because my ~ | |
| 189 homework was too hard. True ~ | |
| 190 story. ~ | |
| 191 | |
| 192 | |
| 193 JUSTIFYING TEXT | |
| 194 | |
| 195 Vim has no built-in way of justifying text. However, there is a neat macro | |
| 196 package that does the job. To use this package, execute the following | |
| 197 command: > | |
| 198 | |

208 $VIMRUNTIME/pack/dist/opt/justify/plugin/justify.vim. |
| 7 | 209 |
| 210 An alternative is to filter the text through an external program. Example: > | |
| 211 | |
| 212 :%!fmt | |
| 213 | |
| 214 ============================================================================== | |
| 215 *25.3* Indents and tabs | |
| 216 | |
| 217 Indents can be used to make text stand out from the rest. The example texts | |
| 218 in this manual, for example, are indented by eight spaces or a tab. You would | |
| 219 normally enter this by typing a tab at the start of each line. Take this | |
| 220 text: | |
| 221 the first line ~ | |
| 222 the second line ~ | |
| 223 | |
| 224 This is entered by typing a tab, some text, <Enter>, tab and more text. | |
| 225 The 'autoindent' option inserts indents automatically: > | |
| 226 | |
| 227 :set autoindent | |
| 228 | |
| 229 When a new line is started it gets the same indent as the previous line. In | |
| 230 the above example, the tab after the <Enter> is not needed anymore. | |
| 231 | |
| 232 | |
| 233 INCREASING INDENT | |
| 234 | |
| 235 To increase the amount of indent in a line, use the ">" operator. Often this | |
| 236 is used as ">>", which adds indent to the current line. | |
| 237 The amount of indent added is specified with the 'shiftwidth' option. The | |
| 238 default value is 8. To make ">>" insert four spaces worth of indent, for | |
| 239 example, type this: > | |
| 240 | |
| 241 :set shiftwidth=4 | |
| 242 | |
| 243 When used on the second line of the example text, this is what you get: | |
| 244 | |
| 245 the first line ~ | |
| 246 the second line ~ | |
| 247 | |
| 248 "4>>" will increase the indent of four lines. | |
| 249 | |
| 250 | |
| 251 TABSTOP | |
| 252 | |
| 253 If you want to make indents a multiple of 4, you set 'shiftwidth' to 4. But | |
| 1256 | 254 when pressing a <Tab> you still get 8 spaces worth of indent. To change this, |
| 7 | 255 set the 'softtabstop' option: > |
| 256 | |
| 257 :set softtabstop=4 | |
| 258 | |
| 259 This will make the <Tab> key insert 4 spaces worth of indent. If there are | |
| 260 already four spaces, a <Tab> character is used (saving seven characters in the | |
| 261 file). (If you always want spaces and no tab characters, set the 'expandtab' | |
| 262 option.) | |
| 263 | |
| 264 Note: | |
| 265 You could set the 'tabstop' option to 4. However, if you edit the | |
| 266 file another time, with 'tabstop' set to the default value of 8, it | |
| 267 will look wrong. In other programs and when printing the indent will | |
| 268 also be wrong. Therefore it is recommended to keep 'tabstop' at eight | |
| 269 all the time. That's the standard value everywhere. | |
| 270 | |
| 271 | |
| 272 CHANGING TABS | |
| 273 | |
| 274 You edit a file which was written with a tabstop of 3. In Vim it looks ugly, | |
| 275 because it uses the normal tabstop value of 8. You can fix this by setting | |
| 276 'tabstop' to 3. But you have to do this every time you edit this file. | |
| 277 Vim can change the use of tabstops in your file. First, set 'tabstop' to | |
| 278 make the indents look good, then use the ":retab" command: > | |
| 279 | |
| 280 :set tabstop=3 | |
| 281 :retab 8 | |
| 282 | |
| 283 The ":retab" command will change 'tabstop' to 8, while changing the text such | |
| 284 that it looks the same. It changes spans of white space into tabs and spaces | |
| 285 for this. You can now write the file. Next time you edit it the indents will | |
| 286 be right without setting an option. | |
| 287 Warning: When using ":retab" on a program, it may change white space inside | |
| 288 a string constant. Therefore it's a good habit to use "\t" instead of a | |
| 289 real tab. | |
| 290 | |
| 291 ============================================================================== | |
| 292 *25.4* Dealing with long lines | |
| 293 | |
| 294 Sometimes you will be editing a file that is wider than the number of columns | |
| 295 in the window. When that occurs, Vim wraps the lines so that everything fits | |
| 296 on the screen. | |
| 297 If you switch the 'wrap' option off, each line in the file shows up as one | |
| 298 line on the screen. Then the ends of the long lines disappear off the screen | |
| 299 to the right. | |
| 300 When you move the cursor to a character that can't be seen, Vim will scroll | |
| 301 the text to show it. This is like moving a viewport over the text in the | |
| 302 horizontal direction. | |
| 303 By default, Vim does not display a horizontal scrollbar in the GUI. If you | |
| 304 want to enable one, use the following command: > | |
| 305 | |
| 306 :set guioptions+=b | |
| 307 | |
| 308 One horizontal scrollbar will appear at the bottom of the Vim window. | |
| 309 | |
| 310 If you don't have a scrollbar or don't want to use it, use these commands to | |

311 scroll the text. The cursor will stay in the same place, but it's moved back |
| 7 | 312 into the visible text if necessary. |
| 313 | |
| 314 zh scroll right | |
| 315 4zh scroll four characters right | |
| 316 zH scroll half a window width right | |

| 319 4zl scroll four characters left | |
| 320 zL scroll half a window width left | |
| 321 zs scroll left to put the cursor at the start | |
| 322 | |
| 323 Let's attempt to show this with one line of text. The cursor is on the "w" of | |
| 324 "which". The "current window" above the line indicates the text that is | |
| 325 currently visible. The "window"s below the text indicate the text that is | |
| 326 visible after the command left of it. | |
| 327 | |
| 328 |<-- current window -->| | |
| 329 some long text, part of which is visible in the window ~ | |

| 340 MOVING WITH WRAP OFF | |
| 341 | |
| 342 When 'wrap' is off and the text has scrolled horizontally, you can use the | |
| 343 following commands to move the cursor to a character you can see. Thus text | |
| 344 left and right of the window is ignored. These never cause the text to | |
| 345 scroll: | |

| 358 BREAKING AT WORDS *edit-no-break* | |
| 359 | |
| 360 When preparing text for use by another program, you might have to make | |
| 361 paragraphs without a line break. A disadvantage of using 'nowrap' is that you | |
| 362 can't see the whole sentence you are working on. When 'wrap' is on, words are | |
| 363 broken halfway, which makes them hard to read. | |
| 364 A good solution for editing this kind of paragraph is setting the | |
| 365 'linebreak' option. Vim then breaks lines at an appropriate place when | |
| 366 displaying the line. The text in the file remains unchanged. | |
| 367 Without 'linebreak' text might look like this: | |
| 368 | |

| 393 Set 'textwidth' to zero to avoid a paragraph to be split. | |
| 394 | |
| 395 | |
| 396 MOVING BY VISIBLE LINES | |
| 397 | |
| 398 The "j" and "k" commands move to the next and previous lines. When used on | |
| 399 a long line, this means moving a lot of screen lines at once. | |
| 400 To move only one screen line, use the "gj" and "gk" commands. When a line | |
| 401 doesn't wrap they do the same as "j" and "k". When the line does wrap, they | |
| 402 move to a character displayed one line below or above. | |
| 403 You might like to use these mappings, which bind these movement commands to | |
| 404 the cursor keys: > | |
| 405 | |
| 406 :map <Up> gk | |
| 407 :map <Down> gj | |

| 6336 | 410 TURNING A PARAGRAPH INTO ONE LINE *edit-paragraph-join* |
| 7 | 411 |
| 412 If you want to import text into a program like MS-Word, each paragraph should | |
| 413 be a single line. If your paragraphs are currently separated with empty | |
| 414 lines, this is how you turn each paragraph into a single line: > | |
| 415 | |
| 416 :g/./,/^$/join | |
| 417 | |
| 418 That looks complicated. Let's break it up in pieces: | |
| 419 | |
| 420 :g/./ A ":global" command that finds all lines that contain | |
| 421 at least one character. | |
| 422 ,/^$/ A range, starting from the current line (the non-empty | |
| 423 line) until an empty line. | |
| 424 join The ":join" command joins the range of lines together | |
| 425 into one line. | |
| 426 | |
| 427 Starting with this text, containing eight lines broken at column 30: | |
| 428 | |
| 429 +----------------------------------+ | |
| 430 |A letter generation program | | |
| 431 |for a bank. They wanted to | | |
| 432 |send out a special, | | |
| 433 |personalized letter. | | |
| 434 | | | |
| 435 |To their richest 1000 | | |
| 436 |customers. Unfortunately for | | |
| 437 |the programmer, | | |
| 438 +----------------------------------+ | |
| 439 | |
| 440 You end up with two lines: | |
| 441 | |
| 442 +----------------------------------+ | |
| 443 |A letter generation program for a | | |
| 444 |bank. They wanted to send out a s| | |
| 445 |pecial, personalized letter. | | |
| 446 |To their richest 1000 customers. | | |
| 447 |Unfortunately for the programmer, | | |
| 448 +----------------------------------+ | |
| 449 | |
| 450 Note that this doesn't work when the separating line is blank but not empty; | |
| 451 when it contains spaces and/or tabs. This command does work with blank lines: | |
| 452 > | |
| 453 :g/\S/,/^\s*$/join | |
| 454 | |
| 455 This still requires a blank or empty line at the end of the file for the last | |
| 456 paragraph to be joined. | |
| 457 | |
| 458 ============================================================================== | |
| 459 *25.5* Editing tables | |
| 460 | |
| 461 Suppose you are editing a table with four columns: | |
| 462 | |
| 463 nice table test 1 test 2 test 3 ~ | |
| 464 input A 0.534 ~ | |
| 465 input B 0.913 ~ | |
| 466 | |
| 467 You need to enter numbers in the third column. You could move to the second | |
| 468 line, use "A", enter a lot of spaces and type the text. | |
| 469 For this kind of editing there is a special option: > | |
| 470 | |
| 471 set virtualedit=all | |
| 472 | |
| 473 Now you can move the cursor to positions where there isn't any text. This is | |
| 474 called "virtual space". Editing a table is a lot easier this way. | |
| 475 Move the cursor by searching for the header of the last column: > | |
| 476 | |
| 477 /test 3 | |
| 478 | |
| 479 Now press "j" and you are right where you can enter the value for "input A". | |
| 480 Typing "0.693" results in: | |
| 481 | |
| 482 nice table test 1 test 2 test 3 ~ | |
| 483 input A 0.534 0.693 ~ | |
| 484 input B 0.913 ~ | |
| 485 | |
| 486 Vim has automatically filled the gap in front of the new text for you. Now, | |
| 487 to enter the next field in this column use "Bj". "B" moves back to the start | |
| 488 of a white space separated word. Then "j" moves to the place where the next | |
| 489 field can be entered. | |
| 490 | |
| 491 Note: | |
| 492 You can move the cursor anywhere in the display, also beyond the end | |
| 493 of a line. But Vim will not insert spaces there, until you insert a | |
| 494 character in that position. | |
| 495 | |
| 496 | |
| 497 COPYING A COLUMN | |
| 498 | |
| 499 You want to add a column, which should be a copy of the third column and | |
| 500 placed before the "test 1" column. Do this in seven steps: | |
| 501 1. Move the cursor to the left upper corner of this column, e.g., with | |
| 502 "/test 3". | |
| 503 2. Press CTRL-V to start blockwise Visual mode. | |
| 504 3. Move the cursor down two lines with "2j". You are now in "virtual space": | |
| 505 the "input B" line of the "test 3" column. | |
| 506 4. Move the cursor right, to include the whole column in the selection, plus | |
| 507 the space that you want between the columns. "9l" should do it. | |
| 508 5. Yank the selected rectangle with "y". | |
| 509 6. Move the cursor to "test 1", where the new column must be placed. | |
| 510 7. Press "P". | |
| 511 | |
| 512 The result should be: | |
| 513 | |
| 514 nice table test 3 test 1 test 2 test 3 ~ | |
| 515 input A 0.693 0.534 0.693 ~ | |
| 516 input B 0.913 ~ | |
| 517 | |
| 518 Notice that the whole "test 1" column was shifted right, also the line where | |
| 519 the "test 3" column didn't have text. | |
| 520 | |
| 521 Go back to non-virtual cursor movements with: > | |
| 522 | |
| 523 :set virtualedit= | |
| 524 | |
| 525 | |
| 526 VIRTUAL REPLACE MODE | |
| 527 | |
| 528 The disadvantage of using 'virtualedit' is that it "feels" different. You | |
| 529 can't recognize tabs or spaces beyond the end of line when moving the cursor | |
| 530 around. Another method can be used: Virtual Replace mode. | |
| 531 Suppose you have a line in a table that contains both tabs and other | |
| 532 characters. Use "rx" on the first tab: | |
| 533 | |
| 534 inp 0.693 0.534 0.693 ~ | |
| 535 | |
| 536 | | |
| 537 rx | | |
| 538 V | |
| 539 | |
| 540 inpx0.693 0.534 0.693 ~ | |
| 541 | |
| 542 The layout is messed up. To avoid that, use the "gr" command: | |
| 543 | |
| 544 inp 0.693 0.534 0.693 ~ | |
| 545 | |
| 546 | | |
| 547 grx | | |
| 548 V | |
| 549 | |
| 550 inpx 0.693 0.534 0.693 ~ | |
| 551 | |
| 552 What happens is that the "gr" command makes sure the new character takes the | |
| 553 right amount of screen space. Extra spaces or tabs are inserted to fill the | |
| 554 gap. Thus what actually happens is that a tab is replaced by "x" and then | |
|

555 blanks added to make the text after it keep its place. In this case a |
| 7 | 556 tab is inserted. |
| 557 When you need to replace more than one character, you use the "R" command | |
| 558 to go to Replace mode (see |04.9|). This messes up the layout and replaces | |
| 559 the wrong characters: | |
| 560 | |
| 561 inp 0 0.534 0.693 ~ | |
| 562 | |
| 563 | | |
| 564 R0.786 | | |
| 565 V | |
| 566 | |
| 567 inp 0.78634 0.693 ~ | |
| 568 | |
| 569 The "gR" command uses Virtual Replace mode. This preserves the layout: | |
| 570 | |
| 571 inp 0 0.534 0.693 ~ | |
| 572 | |
| 573 | | |
| 574 gR0.786 | | |
| 575 V | |
| 576 | |
| 577 inp 0.786 0.534 0.693 ~ | |
