| 7 Editing with multiple windows and buffers. *windows* *buffers* | |
| 8 | |
| 9 The commands which have been added to use multiple windows and buffers are | |
| 10 explained here. Additionally, there are explanations for commands that work | |
| 11 differently when used in combination with more than one window. | |
| 12 | |
| 13 The basics are explained in chapter 7 and 8 of the user manual |usr_07.txt| | |

| 7 | 40 A window is a viewport onto a buffer. You can use multiple windows on one |
| 41 buffer, or several windows on different buffers. | |
| 42 | |
| 43 A buffer is a file loaded into memory for editing. The original file remains | |
| 44 unchanged until you write the buffer to the file. | |
| 45 | |
| 46 A buffer can be in one of three states: | |
| 47 | |
| 48 *active-buffer* | |
| 49 active: The buffer is displayed in a window. If there is a file for this | |
| 50 buffer, it has been read into the buffer. The buffer may have been | |
| 51 modified since then and thus be different from the file. | |
| 52 *hidden-buffer* | |
| 53 hidden: The buffer is not displayed. If there is a file for this buffer, it | |
| 54 has been read into the buffer. Otherwise it's the same as an active | |
| 55 buffer, you just can't see it. | |
| 56 *inactive-buffer* | |
| 57 inactive: The buffer is not displayed and does not contain anything. Options | |
| 58 for the buffer are remembered if the file was once loaded. It can | |
| 59 contain marks from the |viminfo| file. But the buffer doesn't | |
| 60 contain text. | |
| 61 | |
| 62 In a table: | |
| 63 | |
| 64 state displayed loaded ":buffers" ~ | |
| 65 in window shows ~ | |
| 66 active yes yes 'a' | |
| 67 hidden no yes 'h' | |
| 68 inactive no no ' ' | |
| 69 | |
| 70 Note: All CTRL-W commands can also be executed with |:wincmd|, for those | |
| 71 places where a Normal mode command can't be used or is inconvenient. | |
| 72 | |
| 674 | 73 The main Vim window can hold several split windows. There are also tab pages |
| 74 |tab-page|, each of which can hold multiple windows. | |

| 91 2. Starting Vim *windows-starting* | |
| 92 | |
| 93 By default, Vim starts with one window, just like Vi. | |
| 94 | |
| 95 The "-o" and "-O" arguments to Vim can be used to open a window for each file | |
| 96 in the argument list. The "-o" argument will split the windows horizontally; | |
| 97 the "-O" argument will split the windows vertically. If both "-o" and "-O" | |
| 98 are given, the last one encountered will be used to determine the split | |
| 99 orientation. For example, this will open three windows, split horizontally: > | |
| 100 vim -o file1 file2 file3 | |
| 101 | |
| 102 "-oN", where N is a decimal number, opens N windows split horizontally. If | |
| 103 there are more file names than windows, only N windows are opened and some | |
| 104 files do not get a window. If there are more windows than file names, the | |
| 105 last few windows will be editing empty buffers. Similarly, "-ON" opens N | |
| 106 windows split vertically, with the same restrictions. | |
| 107 | |
| 108 If there are many file names, the windows will become very small. You might | |
| 109 want to set the 'winheight' and/or 'winwidth' options to create a workable | |
| 110 situation. | |
| 111 | |
| 112 Buf/Win Enter/Leave |autocommand|s are not executed when opening the new | |
| 113 windows and reading the files, that's only done when they are really entered. | |
| 114 | |
| 115 *status-line* | |
| 116 A status line will be used to separate windows. The 'laststatus' option tells | |
| 117 when the last window also has a status line: | |
| 118 'laststatus' = 0 never a status line | |
| 119 'laststatus' = 1 status line if there is more than one window | |
| 120 'laststatus' = 2 always a status line | |
| 121 | |
| 122 You can change the contents of the status line with the 'statusline' option. | |
| 40 | 123 This option can be local to the window, so that you can have a different |
| 124 status line in each window. | |
| 7 | 125 |
| 126 Normally, inversion is used to display the status line. This can be changed | |
| 127 with the 's' character in the 'highlight' option. For example, "sb" sets it to | |
| 128 bold characters. If no highlighting is used for the status line ("sn"), the | |
| 129 '^' character is used for the current window, and '=' for other windows. If | |
| 130 the mouse is supported and enabled with the 'mouse' option, a status line can | |
| 131 be dragged to resize windows. | |
| 132 | |
| 133 Note: If you expect your status line to be in reverse video and it isn't, | |
| 134 check if the 'highlight' option contains "si". In version 3.0, this meant to | |
| 135 invert the status line. Now it should be "sr", reverse the status line, as | |
| 136 "si" now stands for italic! If italic is not available on your terminal, the | |
| 137 status line is inverted anyway; you will only see this problem on terminals | |
| 138 that have termcap codes for italics. | |
| 139 | |
| 140 ============================================================================== | |
| 141 3. Opening and closing a window *opening-window* *E36* | |
| 142 | |
| 143 CTRL-W s *CTRL-W_s* | |
| 144 CTRL-W S *CTRL-W_S* | |
| 145 CTRL-W CTRL-S *CTRL-W_CTRL-S* | |
| 5741 | 146 :[N]sp[lit] [++opt] [+cmd] [file] *:sp* *:split* |
| 7 | 147 Split current window in two. The result is two viewports on |
| 5741 | 148 the same file. |
| 149 | |
| 150 Make the new window N high (default is to use half the height | |
| 151 of the current window). Reduces the current window height to | |
| 152 create room (and others, if the 'equalalways' option is set, | |
| 153 'eadirection' isn't "hor", and one of them is higher than the | |
| 154 current or the new window). | |
| 155 | |
| 156 If [file] is given it will be edited in the new window. If it | |
| 157 is not loaded in any buffer, it will be read. Else the new | |
| 158 window will use the already loaded buffer. | |
| 159 | |
| 7 | 160 Note: CTRL-S does not work on all terminals and might block |
| 161 further input, use CTRL-Q to get going again. | |
| 162 Also see |++opt| and |+cmd|. | |
| 17571 | 163 *E242* |
| 164 Be careful when splitting a window in an autocommand, it may | |
| 165 mess up the window layout if this happens while making other | |
| 166 window layout changes. | |
| 7 | 167 |
| 168 CTRL-W CTRL-V *CTRL-W_CTRL-V* | |
| 169 CTRL-W v *CTRL-W_v* | |
| 170 :[N]vs[plit] [++opt] [+cmd] [file] *:vs* *:vsplit* | |
| 1354 | 171 Like |:split|, but split vertically. The windows will be |
| 172 spread out horizontally if | |
| 173 1. a width was not specified, | |
| 174 2. 'equalalways' is set, | |
| 175 3. 'eadirection' isn't "ver", and | |
| 1622 | 176 4. one of the other windows is wider than the current or new |
| 1354 | 177 window. |
| 7 | 178 Note: In other places CTRL-Q does the same as CTRL-V, but here |
| 179 it doesn't! | |
| 180 | |
| 181 CTRL-W n *CTRL-W_n* | |
| 182 CTRL-W CTRL_N *CTRL-W_CTRL-N* | |
| 183 :[N]new [++opt] [+cmd] *:new* | |
| 184 Create a new window and start editing an empty file in it. | |
| 185 Make new window N high (default is to use half the existing | |
| 186 height). Reduces the current window height to create room (and | |
| 187 others, if the 'equalalways' option is set and 'eadirection' | |
| 188 isn't "hor"). | |
| 189 Also see |++opt| and |+cmd|. | |
| 190 If 'fileformats' is not empty, the first format given will be | |
| 191 used for the new buffer. If 'fileformats' is empty, the | |
| 192 'fileformat' of the current buffer is used. This can be | |
| 193 overridden with the |++opt| argument. | |
| 194 Autocommands are executed in this order: | |
| 195 1. WinLeave for the current window | |
| 196 2. WinEnter for the new window | |
| 197 3. BufLeave for the current buffer | |
| 198 4. BufEnter for the new buffer | |
| 3465 | 199 This behaves like a ":split" first, and then an ":enew" |
| 200 command. | |
| 7 | 201 |
| 202 :[N]vne[w] [++opt] [+cmd] [file] *:vne* *:vnew* | |
| 203 Like |:new|, but split vertically. If 'equalalways' is set | |
| 204 and 'eadirection' isn't "ver" the windows will be spread out | |
| 205 horizontally, unless a width was specified. | |
| 206 | |
| 207 :[N]new [++opt] [+cmd] {file} | |
| 208 :[N]sp[lit] [++opt] [+cmd] {file} *:split_f* | |
| 3465 | 209 Create a new window and start editing file {file} in it. This |
| 210 behaves like a ":split" first, and then an ":e" command. | |
| 7 | 211 If [+cmd] is given, execute the command when the file has been |
| 212 loaded |+cmd|. | |
| 213 Also see |++opt|. | |
| 214 Make new window N high (default is to use half the existing | |
| 215 height). Reduces the current window height to create room | |
| 216 (and others, if the 'equalalways' option is set). | |
| 217 | |
| 218 :[N]sv[iew] [++opt] [+cmd] {file} *:sv* *:sview* *splitview* | |
| 219 Same as ":split", but set 'readonly' option for this buffer. | |
| 220 | |
| 16944 | 221 :[N]sf[ind] [++opt] [+cmd] {file} *:sf* *:sfi* *:sfind* *splitfind* |
| 1668 | 222 Same as ":split", but search for {file} in 'path' like in |
| 223 |:find|. Doesn't split if {file} is not found. | |
| 7 | 224 |

| 6398 | 314 < |
| 18456 | 315 When closing a help window, Vim will try to restore the |
| 316 previous window layout |:helpclose|. | |
| 317 | |
| 6398 | 318 :q[uit]! |
| 319 :{count}q[uit]! | |
| 320 Without {count}: Quit the current window. If {count} is | |
| 321 given quit the {count} window. | |
| 7 | 322 |
| 6398 | 323 If this was the last window for a buffer, any changes to that |
| 324 buffer are lost. When quitting the last window (not counting | |
| 325 help windows), exit Vim. The contents of the buffer are lost, | |
| 326 even when 'hidden' is set. | |
| 327 | |
| 328 :clo[se][!] | |
| 329 :{count}clo[se][!] | |
| 7 | 330 CTRL-W c *CTRL-W_c* *:clo* *:close* |
| 6398 | 331 Without {count}: Close the current window. If {count} is |
| 332 given close the {count} window. | |
| 333 | |
| 334 When the 'hidden' option is set, or when the buffer was | |
| 335 changed and the [!] is used, the buffer becomes hidden (unless | |
| 336 there is another window editing it). | |
| 337 | |
| 674 | 338 When there is only one window in the current tab page and |
| 339 there is another tab page, this closes the current tab page. | |
| 340 |tab-page|. | |
| 6398 | 341 |
| 7 | 342 This command fails when: *E444* |
| 343 - There is only one window on the screen. | |
| 344 - When 'hidden' is not set, [!] is not used, the buffer has | |
| 345 changes, and there is no other window on this buffer. | |
| 346 Changes to the buffer are not written and won't get lost, so | |
| 347 this is a "safe" command. | |
| 348 | |
| 349 CTRL-W CTRL-C *CTRL-W_CTRL-C* | |
| 350 You might have expected that CTRL-W CTRL-C closes the current | |
| 351 window, but that does not work, because the CTRL-C cancels the | |
| 352 command. | |
| 353 | |
| 354 *:hide* | |
| 6398 | 355 :hid[e] |
| 356 :{count}hid[e] | |
| 12254 | 357 Without {count}: Quit the current window, unless it is the |
| 358 last window on the screen. | |
| 359 If {count} is given quit the {count} window. | |
| 6398 | 360 |
| 361 The buffer becomes hidden (unless there is another window | |
| 6421 | 362 editing it or 'bufhidden' is "unload", "delete" or "wipe"). |
| 363 If the window is the last one in the current tab page the tab | |
| 364 page is closed. |tab-page| | |
| 6398 | 365 |
| 366 The value of 'hidden' is irrelevant for this command. Changes | |
| 367 to the buffer are not written and won't get lost, so this is a | |
| 368 "safe" command. | |
| 7 | 369 |
| 370 :hid[e] {cmd} Execute {cmd} with 'hidden' is set. The previous value of | |
| 371 'hidden' is restored after {cmd} has been executed. | |
| 372 Example: > | |
| 373 :hide edit Makefile | |
| 374 < This will edit "Makefile", and hide the current buffer if it | |
| 375 has any changes. | |

| 378 :{count}on[ly][!] | |
| 7 | 379 CTRL-W o *CTRL-W_o* *E445* |
| 380 CTRL-W CTRL-O *CTRL-W_CTRL-O* *:on* *:only* | |
| 6398 | 381 Make the current window the only one on the screen. All other |
| 382 windows are closed. For {count} see |:quit| command. | |
| 383 | |
| 7 | 384 When the 'hidden' option is set, all buffers in closed windows |
| 385 become hidden. | |
| 6398 | 386 |
| 7 | 387 When 'hidden' is not set, and the 'autowrite' option is set, |
| 388 modified buffers are written. Otherwise, windows that have | |
| 389 buffers that are modified are not removed, unless the [!] is | |
| 390 given, then they become hidden. But modified buffers are | |
| 391 never abandoned, so changes cannot get lost. | |

| 432 CTRL-W CTRL-T Move cursor to top-left window. | |
| 433 | |
| 434 CTRL-W b *CTRL-W_b* *CTRL-W_CTRL-B* | |
| 435 CTRL-W CTRL-B Move cursor to bottom-right window. | |
| 436 | |
| 437 CTRL-W p *CTRL-W_p* *CTRL-W_CTRL-P* | |
| 438 CTRL-W CTRL-P Go to previous (last accessed) window. | |
| 439 | |
| 440 *CTRL-W_P* *E441* | |
| 441 CTRL-W P Go to preview window. When there is no preview window this is | |
| 442 an error. | |
| 443 {not available when compiled without the |+quickfix| feature} | |
| 444 | |
| 445 If Visual mode is active and the new window is not for the same buffer, the | |
| 446 Visual mode is ended. If the window is on the same buffer, the cursor | |
| 447 position is set to keep the same Visual area selected. | |
| 448 | |
| 449 *:winc* *:wincmd* | |
| 450 These commands can also be executed with ":wincmd": | |
| 451 | |
| 452 :[count]winc[md] {arg} | |
| 453 Like executing CTRL-W [count] {arg}. Example: > | |
| 454 :wincmd j | |
| 455 < Moves to the window below the current one. | |
| 456 This command is useful when a Normal mode cannot be used (for | |
| 457 the |CursorHold| autocommand event). Or when a Normal mode | |
| 458 command is inconvenient. | |
| 459 The count can also be a window number. Example: > | |
| 460 :exe nr . "wincmd w" | |
| 461 < This goes to window "nr". | |
| 462 | |
| 463 ============================================================================== | |
| 464 5. Moving windows around *window-moving* | |
| 465 | |
| 466 CTRL-W r *CTRL-W_r* *CTRL-W_CTRL-R* *E443* | |
| 467 CTRL-W CTRL-R Rotate windows downwards/rightwards. The first window becomes | |
| 468 the second one, the second one becomes the third one, etc. | |
| 469 The last window becomes the first window. The cursor remains | |
| 470 in the same window. | |
| 471 This only works within the row or column of windows that the | |
| 472 current window is in. | |
| 473 | |
| 474 *CTRL-W_R* | |
| 475 CTRL-W R Rotate windows upwards/leftwards. The second window becomes | |
| 476 the first one, the third one becomes the second one, etc. The | |
| 477 first window becomes the last window. The cursor remains in | |
| 478 the same window. | |
| 479 This only works within the row or column of windows that the | |
| 480 current window is in. | |
| 481 | |
| 482 CTRL-W x *CTRL-W_x* *CTRL-W_CTRL-X* | |
| 483 CTRL-W CTRL-X Without count: Exchange current window with next one. If there | |
| 484 is no next window, exchange with previous window. | |
| 485 With count: Exchange current window with Nth window (first | |
| 486 window is 1). The cursor is put in the other window. | |
| 487 When vertical and horizontal window splits are mixed, the | |
| 488 exchange is only done in the row or column of windows that the | |
| 489 current window is in. | |
| 490 | |
| 491 The following commands can be used to change the window layout. For example, | |
| 492 when there are two vertically split windows, CTRL-W K will change that in | |
| 493 horizontally split windows. CTRL-W H does it the other way around. | |
| 494 | |
| 495 *CTRL-W_K* | |
| 496 CTRL-W K Move the current window to be at the very top, using the full | |
| 497 width of the screen. This works like closing the current | |
| 498 window and then creating another one with ":topleft split", | |
| 499 except that the current window contents is used for the new | |
| 500 window. | |
| 501 | |
| 502 *CTRL-W_J* | |
| 503 CTRL-W J Move the current window to be at the very bottom, using the | |
| 504 full width of the screen. This works like closing the current | |
| 505 window and then creating another one with ":botright split", | |
| 506 except that the current window contents is used for the new | |
| 507 window. | |
| 508 | |
| 509 *CTRL-W_H* | |
| 510 CTRL-W H Move the current window to be at the far left, using the | |
| 511 full height of the screen. This works like closing the | |
| 512 current window and then creating another one with | |
| 513 ":vert topleft split", except that the current window contents | |
| 514 is used for the new window. | |
| 515 | |
| 516 *CTRL-W_L* | |
| 517 CTRL-W L Move the current window to be at the far right, using the full | |
| 518 height of the screen. This works like closing the | |
| 519 current window and then creating another one with | |
| 520 ":vert botright split", except that the current window | |
| 521 contents is used for the new window. | |
| 522 | |
| 826 | 523 *CTRL-W_T* |
| 524 CTRL-W T Move the current window to a new tab page. This fails if | |
| 525 there is only one window in the current tab page. | |
| 526 When a count is specified the new tab page will be opened | |
| 527 before the tab page with this index. Otherwise it comes after | |
| 528 the current tab page. | |
| 529 | |
| 7 | 530 ============================================================================== |
| 531 6. Window resizing *window-resize* | |
| 532 | |
| 533 *CTRL-W_=* | |
| 534 CTRL-W = Make all windows (almost) equally high and wide, but use | |
| 535 'winheight' and 'winwidth' for the current window. | |
| 1123 | 536 Windows with 'winfixheight' set keep their height and windows |
| 537 with 'winfixwidth' set keep their width. | |
| 7 | 538 |
| 539 :res[ize] -N *:res* *:resize* *CTRL-W_-* | |
| 540 CTRL-W - Decrease current window height by N (default 1). | |
| 2152 | 541 If used after |:vertical|: decrease width by N. |
| 7 | 542 |
| 543 :res[ize] +N *CTRL-W_+* | |
| 544 CTRL-W + Increase current window height by N (default 1). | |
| 2152 | 545 If used after |:vertical|: increase width by N. |
| 7 | 546 |
| 547 :res[ize] [N] | |
| 548 CTRL-W CTRL-_ *CTRL-W_CTRL-_* *CTRL-W__* | |
| 549 CTRL-W _ Set current window height to N (default: highest possible). | |
| 550 | |
| 551 z{nr}<CR> Set current window height to {nr}. | |
| 552 | |
| 553 *CTRL-W_<* | |
| 554 CTRL-W < Decrease current window width by N (default 1). | |
| 555 | |
| 556 *CTRL-W_>* | |
| 557 CTRL-W > Increase current window width by N (default 1). | |
| 558 | |
| 559 :vertical res[ize] [N] *:vertical-resize* *CTRL-W_bar* | |
| 560 CTRL-W | Set current window width to N (default: widest possible). | |
| 561 | |
| 562 You can also resize a window by dragging a status line up or down with the | |
| 563 mouse. Or by dragging a vertical separator line left or right. This only | |
| 564 works if the version of Vim that is being used supports the mouse and the | |
| 565 'mouse' option has been set to enable it. | |
| 566 | |
| 567 The option 'winheight' ('wh') is used to set the minimal window height of the | |
| 568 current window. This option is used each time another window becomes the | |
| 569 current window. If the option is '0', it is disabled. Set 'winheight' to a | |
| 570 very large value, e.g., '9999', to make the current window always fill all | |
| 571 available space. Set it to a reasonable value, e.g., '10', to make editing in | |
| 572 the current window comfortable. | |
| 573 | |
| 574 The equivalent 'winwidth' ('wiw') option is used to set the minimal width of | |
| 575 the current window. | |
| 576 | |
| 577 When the option 'equalalways' ('ea') is set, all the windows are automatically | |
| 578 made the same size after splitting or closing a window. If you don't set this | |
| 579 option, splitting a window will reduce the size of the current window and | |
| 580 leave the other windows the same. When closing a window, the extra lines are | |
| 581 given to the window above it. | |
| 582 | |
| 583 The 'eadirection' option limits the direction in which the 'equalalways' | |
| 584 option is applied. The default "both" resizes in both directions. When the | |
| 585 value is "ver" only the heights of windows are equalized. Use this when you | |
| 586 have manually resized a vertically split window and want to keep this width. | |
| 587 Likewise, "hor" causes only the widths of windows to be equalized. | |
| 588 | |
| 589 The option 'cmdheight' ('ch') is used to set the height of the command-line. | |
| 590 If you are annoyed by the |hit-enter| prompt for long messages, set this | |
| 591 option to 2 or 3. | |
| 592 | |
| 593 If there is only one window, resizing that window will also change the command | |
| 594 line height. If there are several windows, resizing the current window will | |
| 595 also change the height of the window below it (and sometimes the window above | |
| 596 it). | |
| 597 | |
| 598 The minimal height and width of a window is set with 'winminheight' and | |
| 599 'winminwidth'. These are hard values, a window will never become smaller. | |
| 600 | |

| 602 7. Argument and buffer list commands *buffer-list* | |
| 603 | |
| 604 args list buffer list meaning ~ | |
| 605 1. :[N]argument [N] 11. :[N]buffer [N] to arg/buf N | |
| 606 2. :[N]next [file ..] 12. :[N]bnext [N] to Nth next arg/buf | |
| 607 3. :[N]Next [N] 13. :[N]bNext [N] to Nth previous arg/buf | |
| 608 4. :[N]previous [N] 14. :[N]bprevious [N] to Nth previous arg/buf | |
| 609 5. :rewind / :first 15. :brewind / :bfirst to first arg/buf | |
| 610 6. :last 16. :blast to last arg/buf | |
| 611 7. :all 17. :ball edit all args/buffers | |
| 612 18. :unhide edit all loaded buffers | |
| 613 19. :[N]bmod [N] to Nth modified buf | |
| 614 | |
| 615 split & args list split & buffer list meaning ~ | |
| 616 21. :[N]sargument [N] 31. :[N]sbuffer [N] split + to arg/buf N | |
| 617 22. :[N]snext [file ..] 32. :[N]sbnext [N] split + to Nth next arg/buf | |
| 618 23. :[N]sNext [N] 33. :[N]sbNext [N] split + to Nth previous arg/buf | |
| 619 24. :[N]sprevious [N] 34. :[N]sbprevious [N] split + to Nth previous arg/buf | |
| 620 25. :srewind / :sfirst 35. :sbrewind / :sbfirst split + to first arg/buf | |
| 621 26. :slast 36. :sblast split + to last arg/buf | |
| 237 | 622 27. :sall 37. :sball edit all args/buffers |
| 7 | 623 38. :sunhide edit all loaded buffers |
| 624 39. :[N]sbmod [N] split + to Nth modified buf | |
| 625 | |
| 626 40. :args list of arguments | |
| 627 41. :buffers list of buffers | |
| 628 | |
| 629 The meaning of [N] depends on the command: | |
| 12559 | 630 [N] is the number of buffers to go forward/backward on 2/12/22/32, |
| 631 3/13/23/33, and 4/14/24/34 | |
| 7 | 632 [N] is an argument number, defaulting to current argument, for 1 and 21 |
| 633 [N] is a buffer number, defaulting to current buffer, for 11 and 31 | |
| 634 [N] is a count for 19 and 39 | |
| 635 | |
| 636 Note: ":next" is an exception, because it must accept a list of file names | |
| 637 for compatibility with Vi. | |
| 638 | |
| 639 | |
| 640 The argument list and multiple windows | |
| 641 -------------------------------------- | |
| 642 | |
| 643 The current position in the argument list can be different for each window. | |
| 644 Remember that when doing ":e file", the position in the argument list stays | |
| 645 the same, but you are not editing the file at that position. To indicate | |
| 646 this, the file message (and the title, if you have one) shows | |
| 647 "(file (N) of M)", where "(N)" is the current position in the file list, and | |
| 648 "M" the number of files in the file list. | |
| 649 | |
| 650 All the entries in the argument list are added to the buffer list. Thus, you | |
| 651 can also get to them with the buffer list commands, like ":bnext". | |
| 652 | |
| 653 :[N]al[l][!] [N] *:al* *:all* *:sal* *:sall* | |
| 654 :[N]sal[l][!] [N] | |
| 655 Rearrange the screen to open one window for each argument. | |
| 656 All other windows are closed. When a count is given, this is | |
| 657 the maximum number of windows to open. | |
| 699 | 658 With the |:tab| modifier open a tab page for each argument. |
| 659 When there are more arguments than 'tabpagemax' further ones | |
| 660 become split windows in the last tab page. | |
| 7 | 661 When the 'hidden' option is set, all buffers in closed windows |
| 662 become hidden. | |
| 663 When 'hidden' is not set, and the 'autowrite' option is set, | |
| 664 modified buffers are written. Otherwise, windows that have | |
| 665 buffers that are modified are not removed, unless the [!] is | |
| 666 given, then they become hidden. But modified buffers are | |
| 667 never abandoned, so changes cannot get lost. | |
| 668 [N] is the maximum number of windows to open. 'winheight' | |
| 669 also limits the number of windows opened ('winwidth' if | |
| 670 |:vertical| was prepended). | |
| 671 Buf/Win Enter/Leave autocommands are not executed for the new | |
| 672 windows here, that's only done when they are really entered. | |
| 17571 | 673 If autocommands change the window layout while this command is |
| 674 busy an error will be given. *E249* | |
| 7 | 675 |
| 676 :[N]sa[rgument][!] [++opt] [+cmd] [N] *:sa* *:sargument* | |

| 719 The purpose of this command is that it can be used from a | |
| 720 program that wants Vim to edit another file, e.g., a debugger. | |
| 819 | 721 When using the |:tab| modifier each argument is opened in a |
| 722 tab page. The last window is used if it's empty. | |

| 861 The preview window is a special window to show (preview) another file. It is | |
| 862 normally a small window used to show an include file or definition of a | |
| 863 function. | |
| 864 {not available when compiled without the |+quickfix| feature} | |
| 865 | |
| 731 | 866 There can be only one preview window (per tab page). It is created with one |
| 867 of the commands below. The 'previewheight' option can be set to specify the | |
| 868 height of the preview window when it's opened. The 'previewwindow' option is | |
| 869 set in the preview window to be able to recognize it. The 'winfixheight' | |
| 870 option is set to have it keep the same height when opening/closing other | |
| 871 windows. | |

| 7 | 891 *:pta* *:ptag* |
| 892 :pta[g][!] [tagname] | |
| 893 Does ":tag[!] [tagname]" and shows the found tag in a | |
| 894 "Preview" window without changing the current buffer or cursor | |
| 237 | 895 position. If a "Preview" window already exists, it is re-used |
| 7 | 896 (like a help window is). If a new one is opened, |
| 897 'previewheight' is used for the height of the window. See | |
| 898 also |:tag|. | |
| 899 See below for an example. |CursorHold-example| | |
| 900 Small difference from |:tag|: When [tagname] is equal to the | |
| 901 already displayed tag, the position in the matching tag list | |
| 902 is not reset. This makes the CursorHold example work after a | |
| 903 |:ptnext|. | |

916 |:ptag|. |
| 7 | 917 |
| 918 CTRL-W } *CTRL-W_}* | |
| 919 Use identifier under cursor as a tag and perform a :ptag on | |
| 237 | 920 it. Make the new Preview window (if required) N high. If N is |
| 7 | 921 not given, 'previewheight' is used. |
| 922 | |
| 923 CTRL-W g } *CTRL-W_g}* | |
| 924 Use identifier under cursor as a tag and perform a :ptjump on | |
| 237 | 925 it. Make the new Preview window (if required) N high. If N is |
| 7 | 926 not given, 'previewheight' is used. |
| 927 | |
| 928 *:ped* *:pedit* | |
| 929 :ped[it][!] [++opt] [+cmd] {file} | |
| 930 Edit {file} in the preview window. The preview window is | |
| 931 opened like with |:ptag|. The current window and cursor | |
| 932 position isn't changed. Useful example: > | |
| 933 :pedit +/fputc /usr/include/stdio.h | |
| 934 < | |
| 935 *:ps* *:psearch* | |
| 936 :[range]ps[earch][!] [count] [/]pattern[/] | |
| 937 Works like |:ijump| but shows the found match in the preview | |
| 938 window. The preview window is opened like with |:ptag|. The | |
| 939 current window and cursor position isn't changed. Useful | |
| 940 example: > | |
| 941 :psearch popen | |
| 942 < Like with the |:ptag| command, you can use this to | |
| 943 automatically show information about the word under the | |
| 944 cursor. This is less clever than using |:ptag|, but you don't | |
| 945 need a tags file and it will also find matches in system | |
| 946 include files. Example: > | |
| 947 :au! CursorHold *.[ch] nested exe "silent! psearch " . expand("<cword>") | |
| 948 < Warning: This can be slow. | |
| 949 | |
| 950 Example *CursorHold-example* > | |
| 951 | |
| 952 :au! CursorHold *.[ch] nested exe "silent! ptag " . expand("<cword>") | |
| 953 | |
| 954 This will cause a ":ptag" to be executed for the keyword under the cursor, | |
| 955 when the cursor hasn't moved for the time set with 'updatetime'. The "nested" | |
| 956 makes other autocommands be executed, so that syntax highlighting works in the | |
| 957 preview window. The "silent!" avoids an error message when the tag could not | |
| 958 be found. Also see |CursorHold|. To disable this again: > | |
| 959 | |
| 960 :au! CursorHold | |
| 961 | |
| 962 A nice addition is to highlight the found tag, avoid the ":ptag" when there | |
| 963 is no word under the cursor, and a few other things: > | |
| 964 | |
| 965 :au! CursorHold *.[ch] nested call PreviewWord() | |
| 966 :func PreviewWord() | |
| 967 : if &previewwindow " don't do this in the preview window | |

| 1003 ============================================================================== | |
| 1004 11. Using hidden buffers *buffer-hidden* | |
| 1005 | |
| 1006 A hidden buffer is not displayed in a window, but is still loaded into memory. | |
| 1007 This makes it possible to jump from file to file, without the need to read or | |
| 1008 write the file every time you get another buffer in a window. | |
| 1009 | |
| 1010 *:buffer-!* | |
| 1011 If the option 'hidden' ('hid') is set, abandoned buffers are kept for all | |
| 1012 commands that start editing another file: ":edit", ":next", ":tag", etc. The | |
| 1013 commands that move through the buffer list sometimes make the current buffer | |
| 1014 hidden although the 'hidden' option is not set. This happens when a buffer is | |
| 1015 modified, but is forced (with '!') to be removed from a window, and | |
| 1016 'autowrite' is off or the buffer can't be written. | |
| 1017 | |
| 1018 You can make a hidden buffer not hidden by starting to edit it with any | |
| 1019 command. Or by deleting it with the ":bdelete" command. | |
| 1020 | |
| 1021 The 'hidden' is global, it is used for all buffers. The 'bufhidden' option | |
| 1022 can be used to make an exception for a specific buffer. It can take these | |
| 1023 values: | |
| 1024 <empty> Use the value of 'hidden'. | |
| 1025 hide Hide this buffer, also when 'hidden' is not set. | |
| 1026 unload Don't hide but unload this buffer, also when 'hidden' | |
| 1027 is set. | |
| 1028 delete Delete the buffer. | |
| 1029 | |
| 1030 *hidden-quit* | |
| 1031 When you try to quit Vim while there is a hidden, modified buffer, you will | |
| 1032 get an error message and Vim will make that buffer the current buffer. You | |
| 1033 can then decide to write this buffer (":wq") or quit without writing (":q!"). | |
| 1034 Be careful: there may be more hidden, modified buffers! | |
| 1035 | |
| 1036 A buffer can also be unlisted. This means it exists, but it is not in the | |
| 1037 list of buffers. |unlisted-buffer| | |
| 1038 | |
| 1039 | |
| 6945 | 1040 :files[!] [flags] *:files* |
| 1041 :buffers[!] [flags] *:buffers* *:ls* | |
| 1042 :ls[!] [flags] | |
| 1043 Show all buffers. Example: | |
| 7 | 1044 |
| 3920 | 1045 1 #h "/test/text" line 1 ~ |
| 1046 2u "asdf" line 0 ~ | |
| 1047 3 %a + "version.c" line 1 ~ | |
| 7 | 1048 |
| 1049 When the [!] is included the list will show unlisted buffers | |
| 1050 (the term "unlisted" is a bit confusing then...). | |
| 1051 | |
| 1052 Each buffer has a unique number. That number will not change, | |
| 6583 | 1053 thus you can always go to a specific buffer with ":buffer N" |
| 1054 or "N CTRL-^", where N is the buffer number. | |

| 6230 | 1274 :[N]bm[odified][!] [+cmd] [N] *:bm* *:bmodified* *E84* |
| 7 | 1275 Go to [N]th next modified buffer. Note: this command also |
| 1276 finds unlisted buffers. If there is no modified buffer the | |
| 1277 command fails. | |
| 1278 | |
| 6230 | 1279 :[N]sbm[odified] [+cmd] [N] *:sbm* *:sbmodified* |
| 7 | 1280 Split window and go to [N]th next modified buffer. |
| 1281 Respects 'switchbuf' option. | |

| 1286 Rearrange the screen to open one window for each loaded buffer | |
| 1287 in the buffer list. When a count is given, this is the | |
| 1288 maximum number of windows to open. | |
| 1289 | |

| 1291 :[N]sba[ll] [N] Rearrange the screen to open one window for each buffer in | |
| 1292 the buffer list. When a count is given, this is the maximum | |
| 1293 number of windows to open. 'winheight' also limits the number | |
| 1294 of windows opened ('winwidth' if |:vertical| was prepended). | |
| 1295 Buf/Win Enter/Leave autocommands are not executed for the new | |
| 1296 windows here, that's only done when they are really entered. | |
| 1123 | 1297 When the |:tab| modifier is used new windows are opened in a |
| 699 | 1298 new tab, up to 'tabpagemax'. |
| 7 | 1299 |
| 1300 Note: All the commands above that start editing another buffer, keep the | |
| 1301 'readonly' flag as it was. This differs from the ":edit" command, which sets | |
| 1302 the 'readonly' flag each time the file is read. | |

| 1305 12. Special kinds of buffers *special-buffers* | |
| 1306 | |
| 1307 Instead of containing the text of a file, buffers can also be used for other | |
| 1308 purposes. A few options can be set to change the behavior of a buffer: | |
| 1309 'bufhidden' what happens when the buffer is no longer displayed | |
| 1310 in a window. | |
| 1311 'buftype' what kind of a buffer this is | |
| 1312 'swapfile' whether the buffer will have a swap file | |
| 1313 'buflisted' buffer shows up in the buffer list | |
| 1314 | |
| 1315 A few useful kinds of a buffer: | |
| 1316 | |
| 648 | 1317 quickfix Used to contain the error list or the location list. See |
| 1318 |:cwindow| and |:lwindow|. This command sets the 'buftype' | |
| 1319 option to "quickfix". You are not supposed to change this! | |
| 1320 'swapfile' is off. | |
| 7 | 1321 |
| 1322 help Contains a help file. Will only be created with the |:help| | |
| 1323 command. The flag that indicates a help buffer is internal | |
| 1324 and can't be changed. The 'buflisted' option will be reset | |
| 1325 for a help buffer. | |

| 1333 :setlocal bufhidden=delete | |
| 1334 :setlocal noswapfile | |
| 7 | 1335 < The buffer name is the name of the directory and is adjusted |

| 1337 | |
| 1338 scratch Contains text that can be discarded at any time. It is kept | |

| 1347 *unlisted-buffer* | |
| 1348 unlisted The buffer is not in the buffer list. It is not used for | |
| 1349 normal editing, but to show a help file, remember a file name | |
| 1350 or marks. The ":bdelete" command will also set this option, | |
| 1351 thus it doesn't completely delete the buffer. Settings: > | |
