| 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| | |
| 14 |usr_08.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 | |
| 20856 | 140 *filler-lines* |
| 141 The lines after the last buffer line in a window are called filler lines. | |
| 142 These lines start with a tilde (~) character. By default, these are | |
| 143 highlighted as NonText (|hl-NonText|). The EndOfBuffer highlight group | |
| 144 (|hl-EndOfBuffer|) can be used to change the highlighting of filler lines. | |
| 145 | |

| 149 CTRL-W s *CTRL-W_s* | |
| 150 CTRL-W S *CTRL-W_S* | |
| 151 CTRL-W CTRL-S *CTRL-W_CTRL-S* | |
| 5741 | 152 :[N]sp[lit] [++opt] [+cmd] [file] *:sp* *:split* |
| 7 | 153 Split current window in two. The result is two viewports on |
| 5741 | 154 the same file. |
| 18831 | 155 |
| 5741 | 156 Make the new window N high (default is to use half the height |
| 157 of the current window). Reduces the current window height to | |
| 158 create room (and others, if the 'equalalways' option is set, | |
| 159 'eadirection' isn't "hor", and one of them is higher than the | |
| 160 current or the new window). | |
| 161 | |
| 162 If [file] is given it will be edited in the new window. If it | |
| 163 is not loaded in any buffer, it will be read. Else the new | |
| 164 window will use the already loaded buffer. | |
| 165 | |
| 7 | 166 Note: CTRL-S does not work on all terminals and might block |
| 167 further input, use CTRL-Q to get going again. | |
| 168 Also see |++opt| and |+cmd|. | |
| 17571 | 169 *E242* |
| 170 Be careful when splitting a window in an autocommand, it may | |
| 171 mess up the window layout if this happens while making other | |
| 172 window layout changes. | |
| 7 | 173 |
| 174 CTRL-W CTRL-V *CTRL-W_CTRL-V* | |
| 175 CTRL-W v *CTRL-W_v* | |
| 176 :[N]vs[plit] [++opt] [+cmd] [file] *:vs* *:vsplit* | |
| 1354 | 177 Like |:split|, but split vertically. The windows will be |
| 178 spread out horizontally if | |
| 179 1. a width was not specified, | |
| 180 2. 'equalalways' is set, | |
| 181 3. 'eadirection' isn't "ver", and | |
| 1622 | 182 4. one of the other windows is wider than the current or new |
| 1354 | 183 window. |
| 7 | 184 Note: In other places CTRL-Q does the same as CTRL-V, but here |
| 185 it doesn't! | |
| 186 | |
| 187 CTRL-W n *CTRL-W_n* | |
| 188 CTRL-W CTRL_N *CTRL-W_CTRL-N* | |
| 189 :[N]new [++opt] [+cmd] *:new* | |
| 190 Create a new window and start editing an empty file in it. | |
| 191 Make new window N high (default is to use half the existing | |
| 192 height). Reduces the current window height to create room (and | |
| 193 others, if the 'equalalways' option is set and 'eadirection' | |
| 194 isn't "hor"). | |
| 195 Also see |++opt| and |+cmd|. | |
| 196 If 'fileformats' is not empty, the first format given will be | |
| 197 used for the new buffer. If 'fileformats' is empty, the | |
| 198 'fileformat' of the current buffer is used. This can be | |
| 199 overridden with the |++opt| argument. | |
| 200 Autocommands are executed in this order: | |
| 201 1. WinLeave for the current window | |
| 202 2. WinEnter for the new window | |
| 203 3. BufLeave for the current buffer | |
| 204 4. BufEnter for the new buffer | |
| 3465 | 205 This behaves like a ":split" first, and then an ":enew" |
| 206 command. | |
| 7 | 207 |
| 208 :[N]vne[w] [++opt] [+cmd] [file] *:vne* *:vnew* | |
| 209 Like |:new|, but split vertically. If 'equalalways' is set | |
| 210 and 'eadirection' isn't "ver" the windows will be spread out | |
| 211 horizontally, unless a width was specified. | |
| 212 | |
| 213 :[N]new [++opt] [+cmd] {file} | |
| 214 :[N]sp[lit] [++opt] [+cmd] {file} *:split_f* | |
| 3465 | 215 Create a new window and start editing file {file} in it. This |
| 216 behaves like a ":split" first, and then an ":e" command. | |
| 7 | 217 If [+cmd] is given, execute the command when the file has been |
| 218 loaded |+cmd|. | |
| 219 Also see |++opt|. | |
| 220 Make new window N high (default is to use half the existing | |
| 221 height). Reduces the current window height to create room | |
| 222 (and others, if the 'equalalways' option is set). | |
| 223 | |
| 19721 | 224 :[N]sv[iew] [++opt] [+cmd] [file] *:sv* *:sview* *splitview* |
| 7 | 225 Same as ":split", but set 'readonly' option for this buffer. |
| 226 | |
| 16944 | 227 :[N]sf[ind] [++opt] [+cmd] {file} *:sf* *:sfi* *:sfind* *splitfind* |
| 1668 | 228 Same as ":split", but search for {file} in 'path' like in |
| 229 |:find|. Doesn't split if {file} is not found. | |

| 6398 | 320 < |
| 20379 | 321 When closing a help window, and this is not the only window, |
| 322 Vim will try to restore the previous window layout, see | |

| 328 given quit the {count} window. | |
| 7 | 329 |
| 6398 | 330 If this was the last window for a buffer, any changes to that |
| 331 buffer are lost. When quitting the last window (not counting | |
| 332 help windows), exit Vim. The contents of the buffer are lost, | |
| 333 even when 'hidden' is set. | |

| 335 :clo[se][!] | |

| 7 | 337 CTRL-W c *CTRL-W_c* *:clo* *:close* |
| 6398 | 338 Without {count}: Close the current window. If {count} is |
| 339 given close the {count} window. | |
| 340 | |
| 341 When the 'hidden' option is set, or when the buffer was | |
| 342 changed and the [!] is used, the buffer becomes hidden (unless | |
| 343 there is another window editing it). | |
| 18831 | 344 |
| 20379 | 345 When there is only one |edit-window| in the current tab page |
| 346 and there is another tab page, this closes the current tab | |
| 347 page. |tab-page|. | |
| 6398 | 348 |
| 7 | 349 This command fails when: *E444* |
| 350 - There is only one window on the screen. | |
| 351 - When 'hidden' is not set, [!] is not used, the buffer has | |
| 352 changes, and there is no other window on this buffer. | |
| 353 Changes to the buffer are not written and won't get lost, so | |
| 354 this is a "safe" command. | |
| 355 | |
| 356 CTRL-W CTRL-C *CTRL-W_CTRL-C* | |
| 357 You might have expected that CTRL-W CTRL-C closes the current | |
| 358 window, but that does not work, because the CTRL-C cancels the | |
| 359 command. | |
| 360 | |
| 361 *:hide* | |
| 6398 | 362 :hid[e] |
| 363 :{count}hid[e] | |
| 12254 | 364 Without {count}: Quit the current window, unless it is the |
| 365 last window on the screen. | |
| 366 If {count} is given quit the {count} window. | |
| 18831 | 367 |
| 6398 | 368 The buffer becomes hidden (unless there is another window |
| 6421 | 369 editing it or 'bufhidden' is "unload", "delete" or "wipe"). |
| 370 If the window is the last one in the current tab page the tab | |
| 18831 | 371 page is closed. |tab-page| |
| 372 | |
| 6398 | 373 The value of 'hidden' is irrelevant for this command. Changes |
| 374 to the buffer are not written and won't get lost, so this is a | |
| 375 "safe" command. | |
| 7 | 376 |
| 377 :hid[e] {cmd} Execute {cmd} with 'hidden' is set. The previous value of | |
| 378 'hidden' is restored after {cmd} has been executed. | |
| 379 Example: > | |
| 380 :hide edit Makefile | |
| 381 < This will edit "Makefile", and hide the current buffer if it | |
| 382 has any changes. | |

| 387 CTRL-W CTRL-O *CTRL-W_CTRL-O* *:on* *:only* | |
| 6398 | 388 Make the current window the only one on the screen. All other |
| 389 windows are closed. For {count} see |:quit| command. | |
| 18831 | 390 |
| 7 | 391 When the 'hidden' option is set, all buffers in closed windows |
| 392 become hidden. | |
| 18831 | 393 |
| 7 | 394 When 'hidden' is not set, and the 'autowrite' option is set, |
| 395 modified buffers are written. Otherwise, windows that have | |
| 396 buffers that are modified are not removed, unless the [!] is | |
| 397 given, then they become hidden. But modified buffers are | |
| 398 never abandoned, so changes cannot get lost. | |

| 446 | |
| 447 *CTRL-W_P* *E441* | |
| 448 CTRL-W P Go to preview window. When there is no preview window this is | |
| 449 an error. | |
| 450 {not available when compiled without the |+quickfix| feature} | |
| 451 | |
| 452 If Visual mode is active and the new window is not for the same buffer, the | |
| 453 Visual mode is ended. If the window is on the same buffer, the cursor | |
| 454 position is set to keep the same Visual area selected. | |
| 455 | |
| 456 *:winc* *:wincmd* | |
| 457 These commands can also be executed with ":wincmd": | |
| 458 | |
| 459 :[count]winc[md] {arg} | |
| 460 Like executing CTRL-W [count] {arg}. Example: > | |
| 461 :wincmd j | |
| 462 < Moves to the window below the current one. | |
| 463 This command is useful when a Normal mode cannot be used (for | |
| 464 the |CursorHold| autocommand event). Or when a Normal mode | |
| 465 command is inconvenient. | |
| 466 The count can also be a window number. Example: > | |
| 467 :exe nr . "wincmd w" | |
| 468 < This goes to window "nr". | |
| 469 | |
| 470 ============================================================================== | |
| 471 5. Moving windows around *window-moving* | |
| 472 | |
| 473 CTRL-W r *CTRL-W_r* *CTRL-W_CTRL-R* *E443* | |
| 474 CTRL-W CTRL-R Rotate windows downwards/rightwards. The first window becomes | |
| 475 the second one, the second one becomes the third one, etc. | |
| 476 The last window becomes the first window. The cursor remains | |
| 477 in the same window. | |
| 478 This only works within the row or column of windows that the | |
| 479 current window is in. | |
| 480 | |
| 481 *CTRL-W_R* | |
| 482 CTRL-W R Rotate windows upwards/leftwards. The second window becomes | |
| 483 the first one, the third one becomes the second one, etc. The | |
| 484 first window becomes the last window. The cursor remains in | |
| 485 the same window. | |
| 486 This only works within the row or column of windows that the | |
| 487 current window is in. | |
| 488 | |
| 489 CTRL-W x *CTRL-W_x* *CTRL-W_CTRL-X* | |
| 490 CTRL-W CTRL-X Without count: Exchange current window with next one. If there | |
| 491 is no next window, exchange with previous window. | |
| 492 With count: Exchange current window with Nth window (first | |
| 493 window is 1). The cursor is put in the other window. | |
| 494 When vertical and horizontal window splits are mixed, the | |
| 495 exchange is only done in the row or column of windows that the | |
| 496 current window is in. | |
| 497 | |
| 498 The following commands can be used to change the window layout. For example, | |
| 499 when there are two vertically split windows, CTRL-W K will change that in | |
| 500 horizontally split windows. CTRL-W H does it the other way around. | |
| 501 | |
| 502 *CTRL-W_K* | |
| 503 CTRL-W K Move the current window to be at the very top, using the full | |
| 504 width of the screen. This works like closing the current | |
| 505 window and then creating another one with ":topleft split", | |
| 506 except that the current window contents is used for the new | |
| 507 window. | |
| 508 | |
| 509 *CTRL-W_J* | |
| 510 CTRL-W J Move the current window to be at the very bottom, using the | |
| 511 full width of the screen. This works like closing the current | |
| 512 window and then creating another one with ":botright split", | |
| 513 except that the current window contents is used for the new | |
| 514 window. | |
| 515 | |
| 516 *CTRL-W_H* | |
| 517 CTRL-W H Move the current window to be at the far left, using the | |
| 518 full height of the screen. This works like closing the | |
| 519 current window and then creating another one with | |
| 520 ":vert topleft split", except that the current window contents | |
| 521 is used for the new window. | |
| 522 | |
| 523 *CTRL-W_L* | |
| 524 CTRL-W L Move the current window to be at the far right, using the full | |
| 525 height of the screen. This works like closing the | |
| 526 current window and then creating another one with | |
| 527 ":vert botright split", except that the current window | |
| 528 contents is used for the new window. | |
| 529 | |
| 826 | 530 *CTRL-W_T* |
| 531 CTRL-W T Move the current window to a new tab page. This fails if | |
| 532 there is only one window in the current tab page. | |
| 533 When a count is specified the new tab page will be opened | |
| 534 before the tab page with this index. Otherwise it comes after | |
| 535 the current tab page. | |
| 536 | |
| 7 | 537 ============================================================================== |
| 538 6. Window resizing *window-resize* | |
| 539 | |
| 540 *CTRL-W_=* | |
| 541 CTRL-W = Make all windows (almost) equally high and wide, but use | |
| 542 'winheight' and 'winwidth' for the current window. | |
| 1123 | 543 Windows with 'winfixheight' set keep their height and windows |
| 544 with 'winfixwidth' set keep their width. | |
| 7 | 545 |
| 546 :res[ize] -N *:res* *:resize* *CTRL-W_-* | |
| 547 CTRL-W - Decrease current window height by N (default 1). | |
| 2152 | 548 If used after |:vertical|: decrease width by N. |
| 7 | 549 |
| 550 :res[ize] +N *CTRL-W_+* | |
| 551 CTRL-W + Increase current window height by N (default 1). | |
| 2152 | 552 If used after |:vertical|: increase width by N. |
| 7 | 553 |
| 554 :res[ize] [N] | |
| 555 CTRL-W CTRL-_ *CTRL-W_CTRL-_* *CTRL-W__* | |
| 556 CTRL-W _ Set current window height to N (default: highest possible). | |
| 557 | |
| 18489 | 558 :{winnr}res[ize] [+-]N |
| 559 Like `:resize` above, but apply the size to window {winnr} | |
| 560 instead of the current window. | |
| 561 | |
| 7 | 562 z{nr}<CR> Set current window height to {nr}. |
| 563 | |
| 564 *CTRL-W_<* | |
| 565 CTRL-W < Decrease current window width by N (default 1). | |
| 566 | |
| 567 *CTRL-W_>* | |
| 568 CTRL-W > Increase current window width by N (default 1). | |
| 569 | |
| 570 :vertical res[ize] [N] *:vertical-resize* *CTRL-W_bar* | |
| 571 CTRL-W | Set current window width to N (default: widest possible). | |
| 572 | |
| 573 You can also resize a window by dragging a status line up or down with the | |
| 574 mouse. Or by dragging a vertical separator line left or right. This only | |
| 575 works if the version of Vim that is being used supports the mouse and the | |
| 576 'mouse' option has been set to enable it. | |
| 577 | |
| 578 The option 'winheight' ('wh') is used to set the minimal window height of the | |
| 579 current window. This option is used each time another window becomes the | |
| 580 current window. If the option is '0', it is disabled. Set 'winheight' to a | |
| 581 very large value, e.g., '9999', to make the current window always fill all | |
| 582 available space. Set it to a reasonable value, e.g., '10', to make editing in | |
| 583 the current window comfortable. | |
| 584 | |
| 585 The equivalent 'winwidth' ('wiw') option is used to set the minimal width of | |
| 586 the current window. | |
| 587 | |
| 588 When the option 'equalalways' ('ea') is set, all the windows are automatically | |
| 589 made the same size after splitting or closing a window. If you don't set this | |
| 590 option, splitting a window will reduce the size of the current window and | |
| 591 leave the other windows the same. When closing a window, the extra lines are | |
| 592 given to the window above it. | |
| 593 | |
| 594 The 'eadirection' option limits the direction in which the 'equalalways' | |
| 595 option is applied. The default "both" resizes in both directions. When the | |
| 596 value is "ver" only the heights of windows are equalized. Use this when you | |
| 597 have manually resized a vertically split window and want to keep this width. | |
| 598 Likewise, "hor" causes only the widths of windows to be equalized. | |
| 599 | |
| 600 The option 'cmdheight' ('ch') is used to set the height of the command-line. | |
| 601 If you are annoyed by the |hit-enter| prompt for long messages, set this | |
| 602 option to 2 or 3. | |
| 603 | |
| 604 If there is only one window, resizing that window will also change the command | |
| 605 line height. If there are several windows, resizing the current window will | |
| 606 also change the height of the window below it (and sometimes the window above | |
| 607 it). | |
| 608 | |
| 609 The minimal height and width of a window is set with 'winminheight' and | |
| 610 'winminwidth'. These are hard values, a window will never become smaller. | |
| 611 | |

| 614 | |
| 615 args list buffer list meaning ~ | |
| 616 1. :[N]argument [N] 11. :[N]buffer [N] to arg/buf N | |

| 622 7. :all 17. :ball edit all args/buffers | |
| 623 18. :unhide edit all loaded buffers | |
| 624 19. :[N]bmod [N] to Nth modified buf | |
| 625 | |
| 626 split & args list split & buffer list meaning ~ | |
| 627 21. :[N]sargument [N] 31. :[N]sbuffer [N] split + to arg/buf N | |
| 628 22. :[N]snext [file ..] 32. :[N]sbnext [N] split + to Nth next arg/buf | |
| 629 23. :[N]sNext [N] 33. :[N]sbNext [N] split + to Nth previous arg/buf | |
| 630 24. :[N]sprevious [N] 34. :[N]sbprevious [N] split + to Nth previous arg/buf | |
| 631 25. :srewind / :sfirst 35. :sbrewind / :sbfirst split + to first arg/buf | |
| 632 26. :slast 36. :sblast split + to last arg/buf | |
| 237 | 633 27. :sall 37. :sball edit all args/buffers |
| 7 | 634 38. :sunhide edit all loaded buffers |
| 635 39. :[N]sbmod [N] split + to Nth modified buf | |
| 636 | |
| 637 40. :args list of arguments | |
| 638 41. :buffers list of buffers | |
| 639 | |
| 640 The meaning of [N] depends on the command: | |
| 12559 | 641 [N] is the number of buffers to go forward/backward on 2/12/22/32, |
| 642 3/13/23/33, and 4/14/24/34 | |
| 7 | 643 [N] is an argument number, defaulting to current argument, for 1 and 21 |
| 644 [N] is a buffer number, defaulting to current buffer, for 11 and 31 | |
| 645 [N] is a count for 19 and 39 | |
| 646 | |
| 647 Note: ":next" is an exception, because it must accept a list of file names | |
| 648 for compatibility with Vi. | |
| 649 | |
| 650 | |
| 651 The argument list and multiple windows | |
| 652 -------------------------------------- | |
| 653 | |
| 654 The current position in the argument list can be different for each window. | |
| 655 Remember that when doing ":e file", the position in the argument list stays | |
| 656 the same, but you are not editing the file at that position. To indicate | |
| 657 this, the file message (and the title, if you have one) shows | |
| 658 "(file (N) of M)", where "(N)" is the current position in the file list, and | |
| 659 "M" the number of files in the file list. | |
| 660 | |
| 661 All the entries in the argument list are added to the buffer list. Thus, you | |
| 662 can also get to them with the buffer list commands, like ":bnext". | |
| 663 | |
| 664 :[N]al[l][!] [N] *:al* *:all* *:sal* *:sall* | |
| 665 :[N]sal[l][!] [N] | |
| 666 Rearrange the screen to open one window for each argument. | |
| 667 All other windows are closed. When a count is given, this is | |
| 668 the maximum number of windows to open. | |
| 699 | 669 With the |:tab| modifier open a tab page for each argument. |
| 670 When there are more arguments than 'tabpagemax' further ones | |
| 671 become split windows in the last tab page. | |
| 7 | 672 When the 'hidden' option is set, all buffers in closed windows |
| 673 become hidden. | |
| 674 When 'hidden' is not set, and the 'autowrite' option is set, | |
| 675 modified buffers are written. Otherwise, windows that have | |
| 676 buffers that are modified are not removed, unless the [!] is | |
| 677 given, then they become hidden. But modified buffers are | |
| 678 never abandoned, so changes cannot get lost. | |
| 679 [N] is the maximum number of windows to open. 'winheight' | |
| 680 also limits the number of windows opened ('winwidth' if | |

| 730 The purpose of this command is that it can be used from a | |
| 731 program that wants Vim to edit another file, e.g., a debugger. | |
| 819 | 732 When using the |:tab| modifier each argument is opened in a |
| 733 tab page. The last window is used if it's empty. | |

| 870 10. The preview window *preview-window* | |
| 871 | |
| 872 The preview window is a special window to show (preview) another file. It is | |
| 873 normally a small window used to show an include file or definition of a | |
| 874 function. | |
| 875 {not available when compiled without the |+quickfix| feature} | |
| 876 | |
| 731 | 877 There can be only one preview window (per tab page). It is created with one |
| 878 of the commands below. The 'previewheight' option can be set to specify the | |
| 879 height of the preview window when it's opened. The 'previewwindow' option is | |
| 880 set in the preview window to be able to recognize it. The 'winfixheight' | |
| 881 option is set to have it keep the same height when opening/closing other | |
| 882 windows. | |

| 7 | 902 *:pta* *:ptag* |
| 903 :pta[g][!] [tagname] | |
| 904 Does ":tag[!] [tagname]" and shows the found tag in a | |
| 905 "Preview" window without changing the current buffer or cursor | |
| 237 | 906 position. If a "Preview" window already exists, it is re-used |
| 7 | 907 (like a help window is). If a new one is opened, |
| 908 'previewheight' is used for the height of the window. See | |
| 909 also |:tag|. | |
| 910 See below for an example. |CursorHold-example| | |
| 911 Small difference from |:tag|: When [tagname] is equal to the | |
| 912 already displayed tag, the position in the matching tag list | |
| 913 is not reset. This makes the CursorHold example work after a | |
| 914 |:ptnext|. | |

927 |:ptag|. |
| 7 | 928 |
| 929 CTRL-W } *CTRL-W_}* | |
| 930 Use identifier under cursor as a tag and perform a :ptag on | |
| 237 | 931 it. Make the new Preview window (if required) N high. If N is |
| 7 | 932 not given, 'previewheight' is used. |
| 933 | |
| 934 CTRL-W g } *CTRL-W_g}* | |
| 935 Use identifier under cursor as a tag and perform a :ptjump on | |
| 237 | 936 it. Make the new Preview window (if required) N high. If N is |
| 7 | 937 not given, 'previewheight' is used. |
| 938 | |
| 939 *:ped* *:pedit* | |
| 940 :ped[it][!] [++opt] [+cmd] {file} | |
| 941 Edit {file} in the preview window. The preview window is | |
| 942 opened like with |:ptag|. The current window and cursor | |
| 943 position isn't changed. Useful example: > | |
| 944 :pedit +/fputc /usr/include/stdio.h | |
| 945 < | |
| 946 *:ps* *:psearch* | |
| 947 :[range]ps[earch][!] [count] [/]pattern[/] | |
| 948 Works like |:ijump| but shows the found match in the preview | |
| 949 window. The preview window is opened like with |:ptag|. The | |
| 950 current window and cursor position isn't changed. Useful | |
| 951 example: > | |
| 952 :psearch popen | |
| 953 < Like with the |:ptag| command, you can use this to | |
| 954 automatically show information about the word under the | |
| 955 cursor. This is less clever than using |:ptag|, but you don't | |
| 956 need a tags file and it will also find matches in system | |
| 957 include files. Example: > | |
| 22171 | 958 :au! CursorHold *.[ch] ++nested exe "silent! psearch " . expand("<cword>") |
| 7 | 959 < Warning: This can be slow. |
| 960 | |
| 961 Example *CursorHold-example* > | |
| 962 | |
| 22171 | 963 :au! CursorHold *.[ch] ++nested exe "silent! ptag " . expand("<cword>") |
| 7 | 964 |
| 965 This will cause a ":ptag" to be executed for the keyword under the cursor, | |
| 966 when the cursor hasn't moved for the time set with 'updatetime'. The "nested" | |
| 967 makes other autocommands be executed, so that syntax highlighting works in the | |
| 968 preview window. The "silent!" avoids an error message when the tag could not | |
| 969 be found. Also see |CursorHold|. To disable this again: > | |
| 970 | |
| 971 :au! CursorHold | |
| 972 | |
| 973 A nice addition is to highlight the found tag, avoid the ":ptag" when there | |
| 974 is no word under the cursor, and a few other things: > | |
| 975 | |
| 22171 | 976 :au! CursorHold *.[ch] ++nested call PreviewWord() |
| 7 | 977 :func PreviewWord() |
| 978 : if &previewwindow " don't do this in the preview window | |
| 979 : return | |
| 980 : endif | |
| 981 : let w = expand("<cword>") " get the word under cursor | |
| 982 : if w =~ '\a' " if the word contains a letter | |

| 1014 ============================================================================== | |
| 1015 11. Using hidden buffers *buffer-hidden* | |
| 1016 | |
| 1017 A hidden buffer is not displayed in a window, but is still loaded into memory. | |
| 1018 This makes it possible to jump from file to file, without the need to read or | |
| 1019 write the file every time you get another buffer in a window. | |
| 1020 | |
| 1021 *:buffer-!* | |
| 1022 If the option 'hidden' ('hid') is set, abandoned buffers are kept for all | |
| 1023 commands that start editing another file: ":edit", ":next", ":tag", etc. The | |
| 1024 commands that move through the buffer list sometimes make the current buffer | |
| 1025 hidden although the 'hidden' option is not set. This happens when a buffer is | |
| 1026 modified, but is forced (with '!') to be removed from a window, and | |
| 1027 'autowrite' is off or the buffer can't be written. | |
| 1028 | |
| 1029 You can make a hidden buffer not hidden by starting to edit it with any | |
| 1030 command. Or by deleting it with the ":bdelete" command. | |
| 1031 | |
| 1032 The 'hidden' is global, it is used for all buffers. The 'bufhidden' option | |
| 1033 can be used to make an exception for a specific buffer. It can take these | |
| 1034 values: | |
| 1035 <empty> Use the value of 'hidden'. | |
| 1036 hide Hide this buffer, also when 'hidden' is not set. | |
| 1037 unload Don't hide but unload this buffer, also when 'hidden' | |
| 1038 is set. | |
| 1039 delete Delete the buffer. | |
| 1040 | |
| 1041 *hidden-quit* | |
| 1042 When you try to quit Vim while there is a hidden, modified buffer, you will | |
| 1043 get an error message and Vim will make that buffer the current buffer. You | |
| 1044 can then decide to write this buffer (":wq") or quit without writing (":q!"). | |
| 1045 Be careful: there may be more hidden, modified buffers! | |
| 1046 | |
| 1047 A buffer can also be unlisted. This means it exists, but it is not in the | |
| 1048 list of buffers. |unlisted-buffer| | |
| 1049 | |
| 1050 | |
| 6945 | 1051 :files[!] [flags] *:files* |
| 1052 :buffers[!] [flags] *:buffers* *:ls* | |
| 1053 :ls[!] [flags] | |
| 1054 Show all buffers. Example: | |
| 7 | 1055 |
| 3920 | 1056 1 #h "/test/text" line 1 ~ |
| 1057 2u "asdf" line 0 ~ | |
| 1058 3 %a + "version.c" line 1 ~ | |
| 7 | 1059 |
| 1060 When the [!] is included the list will show unlisted buffers | |
| 1061 (the term "unlisted" is a bit confusing then...). | |
| 1062 | |
| 1063 Each buffer has a unique number. That number will not change, | |
| 6583 | 1064 thus you can always go to a specific buffer with ":buffer N" |
| 1065 or "N CTRL-^", where N is the buffer number. | |

| 1307 of windows opened ('winwidth' if |:vertical| was prepended). | |
| 1308 Buf/Win Enter/Leave autocommands are not executed for the new | |

| 1313 Note: All the commands above that start editing another buffer, keep the | |
| 1314 'readonly' flag as it was. This differs from the ":edit" command, which sets | |
| 1315 the 'readonly' flag each time the file is read. | |

| 1318 12. Special kinds of buffers *special-buffers* | |
| 1319 | |
| 1320 Instead of containing the text of a file, buffers can also be used for other | |
| 1321 purposes. A few options can be set to change the behavior of a buffer: | |
| 1322 'bufhidden' what happens when the buffer is no longer displayed | |
| 1323 in a window. | |
| 1324 'buftype' what kind of a buffer this is | |
| 1325 'swapfile' whether the buffer will have a swap file | |
| 1326 'buflisted' buffer shows up in the buffer list | |
| 1327 | |
| 1328 A few useful kinds of a buffer: | |
| 1329 | |
| 648 | 1330 quickfix Used to contain the error list or the location list. See |
| 1331 |:cwindow| and |:lwindow|. This command sets the 'buftype' | |
| 1332 option to "quickfix". You are not supposed to change this! | |
| 1333 'swapfile' is off. | |
| 7 | 1334 |
| 1335 help Contains a help file. Will only be created with the |:help| | |
| 1336 command. The flag that indicates a help buffer is internal | |
| 1337 and can't be changed. The 'buflisted' option will be reset | |
| 1338 for a help buffer. | |

| 1346 :setlocal bufhidden=delete | |
| 1347 :setlocal noswapfile | |

| 1361 unlisted The buffer is not in the buffer list. It is not used for | |
| 1362 normal editing, but to show a help file, remember a file name | |
| 1363 or marks. The ":bdelete" command will also set this option, | |
| 1364 thus it doesn't completely delete the buffer. Settings: > | |
