patch 8.1.1261: no error for quickfix commands with negative range
Problem: No error for quickfix commands with negative range.
Solution: Add ADDR_UNSIGNED and use it for quickfix commands. Make
assert_fails() show the command if the error doesn't match.

| 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 | 43 A window is a viewport onto a buffer. You can use multiple windows on one |
| 44 buffer, or several windows on different buffers. | |
| 45 | |
| 46 A buffer is a file loaded into memory for editing. The original file remains | |
| 47 unchanged until you write the buffer to the file. | |
| 48 | |
| 49 A buffer can be in one of three states: | |
| 50 | |
| 51 *active-buffer* | |
| 52 active: The buffer is displayed in a window. If there is a file for this | |
| 53 buffer, it has been read into the buffer. The buffer may have been | |
| 54 modified since then and thus be different from the file. | |
| 55 *hidden-buffer* | |
| 56 hidden: The buffer is not displayed. If there is a file for this buffer, it | |
| 57 has been read into the buffer. Otherwise it's the same as an active | |
| 58 buffer, you just can't see it. | |
| 59 *inactive-buffer* | |
| 60 inactive: The buffer is not displayed and does not contain anything. Options | |
| 61 for the buffer are remembered if the file was once loaded. It can | |
| 62 contain marks from the |viminfo| file. But the buffer doesn't | |
| 63 contain text. | |
| 64 | |
| 65 In a table: | |
| 66 | |
| 67 state displayed loaded ":buffers" ~ | |
| 68 in window shows ~ | |
| 69 active yes yes 'a' | |
| 70 hidden no yes 'h' | |
| 71 inactive no no ' ' | |
| 72 | |
| 73 Note: All CTRL-W commands can also be executed with |:wincmd|, for those | |
| 74 places where a Normal mode command can't be used or is inconvenient. | |
| 75 | |
| 674 | 76 The main Vim window can hold several split windows. There are also tab pages |
| 77 |tab-page|, each of which can hold multiple windows. | |

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

| 7 | 318 |
| 6398 | 319 If this was the last window for a buffer, any changes to that |
| 320 buffer are lost. When quitting the last window (not counting | |
| 321 help windows), exit Vim. The contents of the buffer are lost, | |
| 322 even when 'hidden' is set. | |

| 324 :clo[se][!] | |

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

| 6398 | 377 Make the current window the only one on the screen. All other |
| 378 windows are closed. For {count} see |:quit| command. | |
| 379 | |
| 7 | 380 When the 'hidden' option is set, all buffers in closed windows |
| 381 become hidden. | |
| 6398 | 382 |
| 7 | 383 When 'hidden' is not set, and the 'autowrite' option is set, |
| 384 modified buffers are written. Otherwise, windows that have | |
| 385 buffers that are modified are not removed, unless the [!] is | |
| 386 given, then they become hidden. But modified buffers are | |
| 387 never abandoned, so changes cannot get lost. | |

| 438 an error. | |
| 439 {not available when compiled without the |+quickfix| feature} | |
| 440 | |
| 441 If Visual mode is active and the new window is not for the same buffer, the | |
| 442 Visual mode is ended. If the window is on the same buffer, the cursor | |
| 443 position is set to keep the same Visual area selected. | |
| 444 | |
| 445 *:winc* *:wincmd* | |
| 446 These commands can also be executed with ":wincmd": | |
| 447 | |
| 448 :[count]winc[md] {arg} | |
| 449 Like executing CTRL-W [count] {arg}. Example: > | |
| 450 :wincmd j | |
| 451 < Moves to the window below the current one. | |
| 452 This command is useful when a Normal mode cannot be used (for | |
| 453 the |CursorHold| autocommand event). Or when a Normal mode | |
| 454 command is inconvenient. | |
| 455 The count can also be a window number. Example: > | |
| 456 :exe nr . "wincmd w" | |
| 457 < This goes to window "nr". | |
| 458 | |
| 459 ============================================================================== | |
| 460 5. Moving windows around *window-moving* | |
| 461 | |
| 462 CTRL-W r *CTRL-W_r* *CTRL-W_CTRL-R* *E443* | |
| 463 CTRL-W CTRL-R Rotate windows downwards/rightwards. The first window becomes | |
| 464 the second one, the second one becomes the third one, etc. | |
| 465 The last window becomes the first window. The cursor remains | |
| 466 in the same window. | |
| 467 This only works within the row or column of windows that the | |
| 468 current window is in. | |
| 469 | |
| 470 *CTRL-W_R* | |
| 471 CTRL-W R Rotate windows upwards/leftwards. The second window becomes | |
| 472 the first one, the third one becomes the second one, etc. The | |
| 473 first window becomes the last window. The cursor remains in | |
| 474 the same window. | |
| 475 This only works within the row or column of windows that the | |
| 476 current window is in. | |
| 477 | |
| 478 CTRL-W x *CTRL-W_x* *CTRL-W_CTRL-X* | |
| 479 CTRL-W CTRL-X Without count: Exchange current window with next one. If there | |
| 480 is no next window, exchange with previous window. | |
| 481 With count: Exchange current window with Nth window (first | |
| 482 window is 1). The cursor is put in the other window. | |
| 483 When vertical and horizontal window splits are mixed, the | |
| 484 exchange is only done in the row or column of windows that the | |
| 485 current window is in. | |
| 486 | |
| 487 The following commands can be used to change the window layout. For example, | |
| 488 when there are two vertically split windows, CTRL-W K will change that in | |
| 489 horizontally split windows. CTRL-W H does it the other way around. | |
| 490 | |
| 491 *CTRL-W_K* | |
| 492 CTRL-W K Move the current window to be at the very top, using the full | |
| 493 width of the screen. This works like closing the current | |
| 494 window and then creating another one with ":topleft split", | |
| 495 except that the current window contents is used for the new | |
| 496 window. | |
| 497 | |
| 498 *CTRL-W_J* | |
| 499 CTRL-W J Move the current window to be at the very bottom, using the | |
| 500 full width of the screen. This works like closing the current | |
| 501 window and then creating another one with ":botright split", | |
| 502 except that the current window contents is used for the new | |
| 503 window. | |
| 504 | |
| 505 *CTRL-W_H* | |
| 506 CTRL-W H Move the current window to be at the far left, using the | |
| 507 full height of the screen. This works like closing the | |
| 508 current window and then creating another one with | |
| 509 ":vert topleft split", except that the current window contents | |
| 510 is used for the new window. | |

| 522 CTRL-W T Move the current window to a new tab page. This fails if | |
| 523 there is only one window in the current tab page. | |
| 524 When a count is specified the new tab page will be opened | |
| 525 before the tab page with this index. Otherwise it comes after | |
| 526 the current tab page. | |

| 7 | 528 ============================================================================== |
| 529 6. Window resizing *window-resize* | |
| 530 | |
| 531 *CTRL-W_=* | |
| 532 CTRL-W = Make all windows (almost) equally high and wide, but use | |
| 533 'winheight' and 'winwidth' for the current window. | |
| 1123 | 534 Windows with 'winfixheight' set keep their height and windows |
| 535 with 'winfixwidth' set keep their width. | |
| 7 | 536 |
| 537 :res[ize] -N *:res* *:resize* *CTRL-W_-* | |
| 538 CTRL-W - Decrease current window height by N (default 1). | |
| 2152 | 539 If used after |:vertical|: decrease width by N. |
| 7 | 540 |
| 541 :res[ize] +N *CTRL-W_+* | |
| 542 CTRL-W + Increase current window height by N (default 1). | |
| 2152 | 543 If used after |:vertical|: increase width by N. |
| 7 | 544 |
| 545 :res[ize] [N] | |
| 546 CTRL-W CTRL-_ *CTRL-W_CTRL-_* *CTRL-W__* | |
| 547 CTRL-W _ Set current window height to N (default: highest possible). | |
| 548 | |
| 549 z{nr}<CR> Set current window height to {nr}. | |
| 550 | |
| 551 *CTRL-W_<* | |
| 552 CTRL-W < Decrease current window width by N (default 1). | |
| 553 | |
| 554 *CTRL-W_>* | |
| 555 CTRL-W > Increase current window width by N (default 1). | |
| 556 | |
| 557 :vertical res[ize] [N] *:vertical-resize* *CTRL-W_bar* | |
| 558 CTRL-W | Set current window width to N (default: widest possible). | |
| 559 | |
| 560 You can also resize a window by dragging a status line up or down with the | |
| 561 mouse. Or by dragging a vertical separator line left or right. This only | |
| 562 works if the version of Vim that is being used supports the mouse and the | |
| 563 'mouse' option has been set to enable it. | |
| 564 | |
| 565 The option 'winheight' ('wh') is used to set the minimal window height of the | |
| 566 current window. This option is used each time another window becomes the | |
| 567 current window. If the option is '0', it is disabled. Set 'winheight' to a | |
| 568 very large value, e.g., '9999', to make the current window always fill all | |
| 569 available space. Set it to a reasonable value, e.g., '10', to make editing in | |
| 570 the current window comfortable. | |
| 571 | |
| 572 The equivalent 'winwidth' ('wiw') option is used to set the minimal width of | |
| 573 the current window. | |
| 574 | |
| 575 When the option 'equalalways' ('ea') is set, all the windows are automatically | |
| 576 made the same size after splitting or closing a window. If you don't set this | |
| 577 option, splitting a window will reduce the size of the current window and | |
| 578 leave the other windows the same. When closing a window, the extra lines are | |
| 579 given to the window above it. | |
| 580 | |
| 581 The 'eadirection' option limits the direction in which the 'equalalways' | |
| 582 option is applied. The default "both" resizes in both directions. When the | |
| 583 value is "ver" only the heights of windows are equalized. Use this when you | |
| 584 have manually resized a vertically split window and want to keep this width. | |
| 585 Likewise, "hor" causes only the widths of windows to be equalized. | |
| 586 | |
| 587 The option 'cmdheight' ('ch') is used to set the height of the command-line. | |
| 588 If you are annoyed by the |hit-enter| prompt for long messages, set this | |
| 589 option to 2 or 3. | |
| 590 | |
| 591 If there is only one window, resizing that window will also change the command | |
| 592 line height. If there are several windows, resizing the current window will | |
| 593 also change the height of the window below it (and sometimes the window above | |
| 594 it). | |
| 595 | |
| 596 The minimal height and width of a window is set with 'winminheight' and | |
| 597 'winminwidth'. These are hard values, a window will never become smaller. | |
| 598 | |

| 610 18. :unhide edit all loaded buffers | |
| 611 19. :[N]bmod [N] to Nth modified buf | |
| 612 | |
| 613 split & args list split & buffer list meaning ~ | |
| 614 21. :[N]sargument [N] 31. :[N]sbuffer [N] split + to arg/buf N | |
| 615 22. :[N]snext [file ..] 32. :[N]sbnext [N] split + to Nth next arg/buf | |

| 237 | 620 27. :sall 37. :sball edit all args/buffers |
| 7 | 621 38. :sunhide edit all loaded buffers |
| 622 39. :[N]sbmod [N] split + to Nth modified buf | |
| 623 | |
| 624 40. :args list of arguments | |
| 625 41. :buffers list of buffers | |
| 626 | |
| 627 The meaning of [N] depends on the command: | |
| 12559 | 628 [N] is the number of buffers to go forward/backward on 2/12/22/32, |
| 629 3/13/23/33, and 4/14/24/34 | |
| 7 | 630 [N] is an argument number, defaulting to current argument, for 1 and 21 |
| 631 [N] is a buffer number, defaulting to current buffer, for 11 and 31 | |
| 632 [N] is a count for 19 and 39 | |
| 633 | |
| 634 Note: ":next" is an exception, because it must accept a list of file names | |
| 635 for compatibility with Vi. | |
| 636 | |
| 637 | |
| 638 The argument list and multiple windows | |
| 639 -------------------------------------- | |
| 640 | |
| 641 The current position in the argument list can be different for each window. | |
| 642 Remember that when doing ":e file", the position in the argument list stays | |
| 643 the same, but you are not editing the file at that position. To indicate | |
| 644 this, the file message (and the title, if you have one) shows | |
| 645 "(file (N) of M)", where "(N)" is the current position in the file list, and | |
| 646 "M" the number of files in the file list. | |
| 647 | |
| 648 All the entries in the argument list are added to the buffer list. Thus, you | |
| 649 can also get to them with the buffer list commands, like ":bnext". | |
| 650 | |
| 651 :[N]al[l][!] [N] *:al* *:all* *:sal* *:sall* | |
| 652 :[N]sal[l][!] [N] | |
| 653 Rearrange the screen to open one window for each argument. | |
| 654 All other windows are closed. When a count is given, this is | |
| 655 the maximum number of windows to open. | |
| 699 | 656 With the |:tab| modifier open a tab page for each argument. |
| 657 When there are more arguments than 'tabpagemax' further ones | |
| 658 become split windows in the last tab page. | |
| 7 | 659 When the 'hidden' option is set, all buffers in closed windows |
| 660 become hidden. | |
| 661 When 'hidden' is not set, and the 'autowrite' option is set, | |
| 662 modified buffers are written. Otherwise, windows that have | |
| 663 buffers that are modified are not removed, unless the [!] is | |
| 664 given, then they become hidden. But modified buffers are | |
| 665 never abandoned, so changes cannot get lost. | |
| 666 [N] is the maximum number of windows to open. 'winheight' | |
| 667 also limits the number of windows opened ('winwidth' if | |
| 668 |:vertical| was prepended). | |
| 669 Buf/Win Enter/Leave autocommands are not executed for the new | |
| 670 windows here, that's only done when they are really entered. | |

| 7 | 714 The |argument-list| is set, like with the |:next| command. |
| 715 The purpose of this command is that it can be used from a | |
| 716 program that wants Vim to edit another file, e.g., a debugger. | |
| 819 | 717 When using the |:tab| modifier each argument is opened in a |
| 718 tab page. The last window is used if it's empty. | |

| 751 :bnext | |

| 753 etc. | |
| 754 < When the current file can't be |abandon|ed and the [!] | |
| 755 is not present, the command fails. | |
| 756 When an error is detected on one buffer, further | |
| 757 buffers will not be visited. | |
| 758 Unlisted buffers are skipped. | |
| 759 The last buffer (or where an error occurred) becomes | |
| 760 the current buffer. | |
| 761 {cmd} can contain '|' to concatenate several commands. | |
| 762 {cmd} must not delete buffers or add buffers to the | |
| 763 buffer list. | |
| 764 Note: While this command is executing, the Syntax | |
| 765 autocommand event is disabled by adding it to | |
| 766 'eventignore'. This considerably speeds up editing | |
| 767 each buffer. | |

| 772 Examples: > | |

| 776 This resets the 'list' option and disables folding in all windows. > | |
| 777 | |
| 778 :bufdo set fileencoding= | update | |
| 779 | |
| 780 This resets the 'fileencoding' in each buffer and writes it if this changed | |
| 781 the buffer. The result is that all buffers will use the 'encoding' encoding | |
| 782 (if conversion works properly). | |

| 786 | |

| 788 :sta[g][!] [tagname] | |
| 789 Does ":tag[!] [tagname]" and splits the window for the found | |
| 790 tag. See also |:tag|. | |
| 791 | |
| 792 CTRL-W ] *CTRL-W_]* *CTRL-W_CTRL-]* | |
| 793 CTRL-W CTRL-] Split current window in two. Use identifier under cursor as a | |
| 6259 | 794 tag and jump to it in the new upper window. |
| 795 In Visual mode uses the Visually selected text as a tag. | |
| 796 Make new window N high. | |
| 7 | 797 |
| 798 *CTRL-W_g]* | |
| 799 CTRL-W g ] Split current window in two. Use identifier under cursor as a | |
| 800 tag and perform ":tselect" on it in the new upper window. | |
| 6259 | 801 In Visual mode uses the Visually selected text as a tag. |
| 7 | 802 Make new window N high. |
| 803 | |
| 804 *CTRL-W_g_CTRL-]* | |
| 805 CTRL-W g CTRL-] Split current window in two. Use identifier under cursor as a | |
| 6259 | 806 tag and perform ":tjump" on it in the new upper window. |
| 807 In Visual mode uses the Visually selected text as a tag. | |
| 808 Make new window N high. | |
| 7 | 809 |
| 810 CTRL-W f *CTRL-W_f* *CTRL-W_CTRL-F* | |
| 811 CTRL-W CTRL-F Split current window in two. Edit file name under cursor. | |
| 820 | 812 Like ":split gf", but window isn't split if the file does not |
| 7 | 813 exist. |
| 814 Uses the 'path' variable as a list of directory names where to | |
| 815 look for the file. Also the path for current file is | |
| 816 used to search for the file name. | |
| 817 If the name is a hypertext link that looks like | |
| 818 "type://machine/path", only "/path" is used. | |
| 819 If a count is given, the count'th matching file is edited. | |
| 820 {not available when the |+file_in_path| feature was disabled | |
| 821 at compile time} | |
| 822 | |
| 681 | 823 CTRL-W F *CTRL-W_F* |
| 824 Split current window in two. Edit file name under cursor and | |
| 825 jump to the line number following the file name. See |gF| for | |
| 826 details on how the line number is obtained. | |
| 839 | 827 {not available when the |+file_in_path| feature was disabled |
| 828 at compile time} | |
| 681 | 829 |
| 820 | 830 CTRL-W gf *CTRL-W_gf* |
| 831 Open a new tab page and edit the file name under the cursor. | |
| 832 Like "tab split" and "gf", but the new tab page isn't created | |
| 833 if the file does not exist. | |
| 834 {not available when the |+file_in_path| feature was disabled | |
| 835 at compile time} | |
| 836 | |
| 839 | 837 CTRL-W gF *CTRL-W_gF* |
| 838 Open a new tab page and edit the file name under the cursor | |
| 839 and jump to the line number following the file name. Like | |
| 840 "tab split" and "gF", but the new tab page isn't created if | |
| 841 the file does not exist. | |
| 842 {not available when the |+file_in_path| feature was disabled | |
| 843 at compile time} | |
| 844 | |
| 16023 | 845 CTRL-W gt *CTRL-W_gt* |
| 846 Go to next tab page, same as `gt`. | |
| 847 | |
| 848 CTRL-W gT *CTRL-W_gT* | |
| 849 Go to previous tab page, same as `gT`. | |
| 850 | |
| 7 | 851 Also see |CTRL-W_CTRL-I|: open window for an included file that includes |
| 852 the keyword under the cursor. | |
| 853 | |
| 854 ============================================================================== | |
| 855 10. The preview window *preview-window* | |
| 856 | |
| 857 The preview window is a special window to show (preview) another file. It is | |
| 858 normally a small window used to show an include file or definition of a | |
| 859 function. | |
| 860 {not available when compiled without the |+quickfix| feature} | |
| 861 | |
| 731 | 862 There can be only one preview window (per tab page). It is created with one |
| 863 of the commands below. The 'previewheight' option can be set to specify the | |
| 864 height of the preview window when it's opened. The 'previewwindow' option is | |
| 865 set in the preview window to be able to recognize it. The 'winfixheight' | |
| 866 option is set to have it keep the same height when opening/closing other | |
| 867 windows. | |
| 7 | 868 |
| 869 *:pta* *:ptag* | |
| 870 :pta[g][!] [tagname] | |
| 871 Does ":tag[!] [tagname]" and shows the found tag in a | |
| 872 "Preview" window without changing the current buffer or cursor | |
| 237 | 873 position. If a "Preview" window already exists, it is re-used |
| 7 | 874 (like a help window is). If a new one is opened, |
| 875 'previewheight' is used for the height of the window. See | |
| 876 also |:tag|. | |
| 877 See below for an example. |CursorHold-example| | |
| 878 Small difference from |:tag|: When [tagname] is equal to the | |
| 879 already displayed tag, the position in the matching tag list | |
| 880 is not reset. This makes the CursorHold example work after a | |
| 881 |:ptnext|. | |
| 882 | |
| 883 CTRL-W z *CTRL-W_z* | |
| 884 CTRL-W CTRL-Z *CTRL-W_CTRL-Z* *:pc* *:pclose* | |
| 885 :pc[lose][!] Close any "Preview" window currently open. When the 'hidden' | |
| 886 option is set, or when the buffer was changed and the [!] is | |
| 887 used, the buffer becomes hidden (unless there is another | |
| 888 window editing it). The command fails if any "Preview" buffer | |
| 889 cannot be closed. See also |:close|. | |
| 890 | |
| 891 *:pp* *:ppop* | |
| 892 :[count]pp[op][!] | |
| 893 Does ":[count]pop[!]" in the preview window. See |:pop| and | |
| 894 |:ptag|. {not in Vi} | |
| 895 | |
| 896 CTRL-W } *CTRL-W_}* | |
| 897 Use identifier under cursor as a tag and perform a :ptag on | |
| 237 | 898 it. Make the new Preview window (if required) N high. If N is |
| 7 | 899 not given, 'previewheight' is used. |
| 900 | |
| 901 CTRL-W g } *CTRL-W_g}* | |
| 902 Use identifier under cursor as a tag and perform a :ptjump on | |
| 237 | 903 it. Make the new Preview window (if required) N high. If N is |
| 7 | 904 not given, 'previewheight' is used. |
| 905 | |
| 906 *:ped* *:pedit* | |
| 907 :ped[it][!] [++opt] [+cmd] {file} | |
| 908 Edit {file} in the preview window. The preview window is | |
| 909 opened like with |:ptag|. The current window and cursor | |
| 910 position isn't changed. Useful example: > | |
| 911 :pedit +/fputc /usr/include/stdio.h | |
| 912 < | |
| 913 *:ps* *:psearch* | |
| 914 :[range]ps[earch][!] [count] [/]pattern[/] | |
| 915 Works like |:ijump| but shows the found match in the preview | |
| 916 window. The preview window is opened like with |:ptag|. The | |
| 917 current window and cursor position isn't changed. Useful | |
| 918 example: > | |
| 919 :psearch popen | |
| 920 < Like with the |:ptag| command, you can use this to | |
| 921 automatically show information about the word under the | |
| 922 cursor. This is less clever than using |:ptag|, but you don't | |
| 923 need a tags file and it will also find matches in system | |
| 924 include files. Example: > | |
| 925 :au! CursorHold *.[ch] nested exe "silent! psearch " . expand("<cword>") | |
| 926 < Warning: This can be slow. | |
| 927 | |
| 928 Example *CursorHold-example* > | |
| 929 | |
| 930 :au! CursorHold *.[ch] nested exe "silent! ptag " . expand("<cword>") | |
| 931 | |
| 932 This will cause a ":ptag" to be executed for the keyword under the cursor, | |
| 933 when the cursor hasn't moved for the time set with 'updatetime'. The "nested" | |
| 934 makes other autocommands be executed, so that syntax highlighting works in the | |
| 935 preview window. The "silent!" avoids an error message when the tag could not | |
| 936 be found. Also see |CursorHold|. To disable this again: > | |
| 937 | |
| 938 :au! CursorHold | |
| 939 | |
| 940 A nice addition is to highlight the found tag, avoid the ":ptag" when there | |
| 941 is no word under the cursor, and a few other things: > | |
| 942 | |
| 943 :au! CursorHold *.[ch] nested call PreviewWord() | |
| 944 :func PreviewWord() | |
| 945 : if &previewwindow " don't do this in the preview window | |
| 946 : return | |
| 947 : endif | |
| 948 : let w = expand("<cword>") " get the word under cursor | |
| 949 : if w =~ '\a' " if the word contains a letter | |
| 950 : | |
| 951 : " Delete any existing highlight before showing another tag | |
| 952 : silent! wincmd P " jump to preview window | |
| 953 : if &previewwindow " if we really get there... | |
| 954 : match none " delete existing highlight | |
| 955 : wincmd p " back to old window | |
| 956 : endif | |
| 957 : | |
| 958 : " Try displaying a matching tag for the word under the cursor | |
| 959 : try | |
| 960 : exe "ptag " . w | |
| 961 : catch | |
| 962 : return | |
| 963 : endtry | |
| 964 : | |
| 965 : silent! wincmd P " jump to preview window | |
| 966 : if &previewwindow " if we really get there... | |
| 967 : if has("folding") | |
| 968 : silent! .foldopen " don't want a closed fold | |
| 969 : endif | |
| 970 : call search("$", "b") " to end of previous line | |
| 971 : let w = substitute(w, '\\', '\\\\', "") | |
| 972 : call search('\<\V' . w . '\>') " position cursor on match | |
| 973 : " Add a match highlight to the word at this position | |
| 974 : hi previewWord term=bold ctermbg=green guibg=green | |
| 975 : exe 'match previewWord "\%' . line(".") . 'l\%' . col(".") . 'c\k*"' | |
| 976 : wincmd p " back to old window | |

| 978 : endif | |
| 979 :endfun | |
| 980 | |
| 981 ============================================================================== | |
| 982 11. Using hidden buffers *buffer-hidden* | |
| 983 | |
| 984 A hidden buffer is not displayed in a window, but is still loaded into memory. | |
| 985 This makes it possible to jump from file to file, without the need to read or | |
| 986 write the file every time you get another buffer in a window. | |
| 987 | |
| 988 *:buffer-!* | |
| 989 If the option 'hidden' ('hid') is set, abandoned buffers are kept for all | |
| 990 commands that start editing another file: ":edit", ":next", ":tag", etc. The | |
| 991 commands that move through the buffer list sometimes make the current buffer | |
| 992 hidden although the 'hidden' option is not set. This happens when a buffer is | |
| 993 modified, but is forced (with '!') to be removed from a window, and | |
| 994 'autowrite' is off or the buffer can't be written. | |
| 995 | |
| 996 You can make a hidden buffer not hidden by starting to edit it with any | |
| 997 command. Or by deleting it with the ":bdelete" command. | |
| 998 | |
| 999 The 'hidden' is global, it is used for all buffers. The 'bufhidden' option | |
| 1000 can be used to make an exception for a specific buffer. It can take these | |
| 1001 values: | |
| 1002 <empty> Use the value of 'hidden'. | |
| 1003 hide Hide this buffer, also when 'hidden' is not set. | |
| 1004 unload Don't hide but unload this buffer, also when 'hidden' | |
| 1005 is set. | |
| 1006 delete Delete the buffer. | |
| 1007 | |
| 1008 *hidden-quit* | |
| 1009 When you try to quit Vim while there is a hidden, modified buffer, you will | |
| 1010 get an error message and Vim will make that buffer the current buffer. You | |
| 1011 can then decide to write this buffer (":wq") or quit without writing (":q!"). | |
| 1012 Be careful: there may be more hidden, modified buffers! | |
| 1013 | |
| 1014 A buffer can also be unlisted. This means it exists, but it is not in the | |
| 1015 list of buffers. |unlisted-buffer| | |
| 1016 | |
| 1017 | |
| 6945 | 1018 :files[!] [flags] *:files* |
| 1019 :buffers[!] [flags] *:buffers* *:ls* | |
| 1020 :ls[!] [flags] | |
| 1021 Show all buffers. Example: | |
| 7 | 1022 |
| 3920 | 1023 1 #h "/test/text" line 1 ~ |
| 1024 2u "asdf" line 0 ~ | |
| 1025 3 %a + "version.c" line 1 ~ | |
| 7 | 1026 |
| 1027 When the [!] is included the list will show unlisted buffers | |
| 1028 (the term "unlisted" is a bit confusing then...). | |
| 1029 | |
| 1030 Each buffer has a unique number. That number will not change, | |
| 6583 | 1031 thus you can always go to a specific buffer with ":buffer N" |
| 1032 or "N CTRL-^", where N is the buffer number. | |
| 7 | 1033 |
| 1034 Indicators (chars in the same column are mutually exclusive): | |
| 1035 u an unlisted buffer (only displayed when [!] is used) | |
| 1036 |unlisted-buffer| | |
| 1037 % the buffer in the current window | |
| 1038 # the alternate buffer for ":e #" and CTRL-^ | |
| 1039 a an active buffer: it is loaded and visible | |
| 1040 h a hidden buffer: It is loaded, but currently not | |
| 1041 displayed in a window |hidden-buffer| | |
| 1042 - a buffer with 'modifiable' off | |
| 1043 = a readonly buffer | |
| 12254 | 1044 R a terminal buffer with a running job |

| 1074 Add file name {fname} to the buffer list, without loading it. | |
| 1075 If "lnum" is specified, the cursor will be positioned at that | |
| 237 | 1076 line when the buffer is first entered. Note that other |

| 1079 :[N]bd[elete][!] *:bd* *:bdel* *:bdelete* *E516* | |
| 1080 :bd[elete][!] [N] | |
| 1081 Unload buffer [N] (default: current buffer) and delete it from | |
| 1082 the buffer list. If the buffer was changed, this fails, | |
| 1083 unless when [!] is specified, in which case changes are lost. | |
| 1084 The file remains unaffected. Any windows for this buffer are | |
| 1085 closed. If buffer [N] is the current buffer, another buffer | |
| 1086 will be displayed instead. This is the most recent entry in | |
| 1087 the jump list that points into a loaded buffer. | |
| 1088 Actually, the buffer isn't completely deleted, it is removed | |
| 1089 from the buffer list |unlisted-buffer| and option values, | |
| 1090 variables and mappings/abbreviations for the buffer are | |

| 1276 12. Special kinds of buffers *special-buffers* | |
| 1277 | |
| 1278 Instead of containing the text of a file, buffers can also be used for other | |
| 1279 purposes. A few options can be set to change the behavior of a buffer: | |
| 1280 'bufhidden' what happens when the buffer is no longer displayed | |
| 1281 in a window. | |
| 1282 'buftype' what kind of a buffer this is | |
| 1283 'swapfile' whether the buffer will have a swap file | |
| 1284 'buflisted' buffer shows up in the buffer list | |
| 1285 | |
| 1286 A few useful kinds of a buffer: | |
| 1287 | |
| 648 | 1288 quickfix Used to contain the error list or the location list. See |
| 1289 |:cwindow| and |:lwindow|. This command sets the 'buftype' | |
| 1290 option to "quickfix". You are not supposed to change this! | |
| 1291 'swapfile' is off. | |
| 7 | 1292 |
| 1293 help Contains a help file. Will only be created with the |:help| | |
| 1294 command. The flag that indicates a help buffer is internal | |
| 1295 and can't be changed. The 'buflisted' option will be reset | |
| 1296 for a help buffer. | |
