| 9 The commands which have been added to use multiple tab pages are explained | |
| 10 here. Additionally, there are explanations for commands that work differently | |

| 22 ============================================================================== | |
| 23 1. Introduction *tab-page-intro* | |
| 24 | |
| 25 A tab page holds one or more windows. You can easily switch between tab | |
| 26 pages, so that you have several collections of windows to work on different | |
| 27 things. | |
| 28 | |
| 29 Usually you will see a list of labels at the top of the Vim window, one for | |
| 30 each tab page. With the mouse you can click on the label to jump to that tab | |
| 31 page. There are other ways to move between tab pages, see below. | |
| 32 | |
| 33 Most commands work only in the current tab page. That includes the |CTRL-W| | |
| 698 | 34 commands, |:windo|, |:all| and |:ball| (when not using the |:tab| modifier). |
| 35 The commands that are aware of other tab pages than the current one are | |
| 36 mentioned below. | |
| 674 | 37 |
| 38 Tabs are also a nice way to edit a buffer temporarily without changing the | |
| 39 current window layout. Open a new tab page, do whatever you want to do and | |
| 40 close the tab page. | |
| 41 | |
| 42 ============================================================================== | |
| 43 2. Commands *tab-page-commands* | |

48 tab page (up to 'tabpagemax'). See |-p| |
| 674 | 49 |
| 706 | 50 A double click with the mouse in the non-GUI tab pages line opens a new, empty |
| 51 tab page. It is placed left of the position of the click. The first click | |
| 52 may select another tab page first, causing an extra screen update. | |
| 53 | |
| 844 | 54 This also works in a few GUI versions, esp. Win32 and Motif. But only when |
| 55 clicking right of the labels. | |
| 56 | |
| 706 | 57 In the GUI tab pages line you can use the right mouse button to open menu. |

| 303 3. Other items *tab-page-other* | |
| 304 | |
| 706 | 305 *tabline-menu* |
| 306 The GUI tab pages line has a popup menu. It is accessed with a right click. | |
| 307 The entries are: | |
| 308 Close Close the tab page under the mouse pointer. The | |
| 309 current one if there is no label under the mouse | |
| 310 pointer. | |
| 311 New Tab Open a tab page, editing an empty buffer. It appears | |
| 312 to the left of the mouse pointer. | |
| 1118 | 313 Open Tab... Like "New Tab" and additionally use a file selector to |
| 706 | 314 select a file to edit. |
| 315 | |
| 674 | 316 Diff mode works per tab page. You can see the diffs between several files |
| 317 within one tab page. Other tab pages can show differences between other | |
| 318 files. | |
| 319 | |
| 819 | 320 Variables local to a tab page start with "t:". |tabpage-variable| |
| 321 | |
| 824 | 322 Currently there is only one option local to a tab page: 'cmdheight'. |

324 *tabnew-autocmd* |
| 675 | 325 The TabLeave and TabEnter autocommand events can be used to do something when |
| 326 switching from one tab page to another. The exact order depends on what you | |
| 327 are doing. When creating a new tab page this works as if you create a new | |
| 328 window on the same buffer and then edit another buffer. Thus ":tabnew" | |
| 329 triggers: | |
| 330 WinLeave leave current window | |
| 331 TabLeave leave current tab page | |
| 6474 | 332 WinEnter enter window in new tab page |
| 675 | 333 TabEnter enter new tab page |
| 334 BufLeave leave current buffer | |
| 335 BufEnter enter new empty buffer | |
| 336 | |
| 678 | 337 When switching to another tab page the order is: |
| 675 | 338 BufLeave |
| 339 WinLeave | |
| 340 TabLeave | |
| 341 TabEnter | |
| 342 WinEnter | |
| 343 BufEnter | |
| 674 | 344 |
| 678 | 345 ============================================================================== |
| 346 4. Setting 'tabline' *setting-tabline* | |
| 347 | |
| 686 | 348 The 'tabline' option specifies what the line with tab pages labels looks like. |
| 349 It is only used when there is no GUI tab line. | |
| 350 | |
| 678 | 351 You can use the 'showtabline' option to specify when you want the line with |
| 352 tab page labels to appear: never, when there is more than one tab page or | |
| 353 always. | |
| 354 | |
| 355 The highlighting of the tab pages line is set with the groups TabLine | |
| 356 TabLineSel and TabLineFill. |hl-TabLine| |hl-TabLineSel| |hl-TabLineFill| | |
| 357 | |
| 1118 | 358 A "+" will be shown for a tab page that has a modified window. The number of |
| 359 windows in a tabpage is also shown. Thus "3+" means three windows and one of | |
| 360 them has a modified buffer. | |
| 361 | |
| 678 | 362 The 'tabline' option allows you to define your preferred way to tab pages |
| 363 labels. This isn't easy, thus an example will be given here. | |
| 364 | |
| 365 For basics see the 'statusline' option. The same items can be used in the | |
| 366 'tabline' option. Additionally, the |tabpagebuflist()|, |tabpagenr()| and | |
| 367 |tabpagewinnr()| functions are useful. | |
| 368 | |
| 1118 | 369 Since the number of tab labels will vary, you need to use an expression for |
| 370 the whole option. Something like: > | |
| 678 | 371 :set tabline=%!MyTabLine() |
| 372 | |
| 373 Then define the MyTabLine() function to list all the tab pages labels. A | |
| 374 convenient method is to split it in two parts: First go over all the tab | |
| 375 pages and define labels for them. Then get the label for each tab page. > | |
| 376 | |
| 377 function MyTabLine() | |
| 378 let s = '' | |
| 379 for i in range(tabpagenr('$')) | |
| 681 | 380 " select the highlighting |
| 678 | 381 if i + 1 == tabpagenr() |
| 382 let s .= '%#TabLineSel#' | |
| 383 else | |
| 384 let s .= '%#TabLine#' | |
| 385 endif | |
| 681 | 386 |
| 387 " set the tab page number (for mouse clicks) | |
| 388 let s .= '%' . (i + 1) . 'T' | |
| 389 | |
| 390 " the label is made by MyTabLabel() | |
| 678 | 391 let s .= ' %{MyTabLabel(' . (i + 1) . ')} ' |
| 392 endfor | |
| 681 | 393 |
| 394 " after the last tab fill with TabLineFill and reset tab page nr | |
| 395 let s .= '%#TabLineFill#%T' | |
| 396 | |
| 397 " right-align the label to close the current tab page | |
| 398 if tabpagenr('$') > 1 | |
| 399 let s .= '%=%#TabLine#%999Xclose' | |
| 400 endif | |
| 401 | |
| 678 | 402 return s |
| 403 endfunction | |
| 404 | |
| 405 Now the MyTabLabel() function is called for each tab page to get its label. > | |
| 406 | |
| 407 function MyTabLabel(n) | |
| 408 let buflist = tabpagebuflist(a:n) | |
| 409 let winnr = tabpagewinnr(a:n) | |
| 410 return bufname(buflist[winnr - 1]) | |
| 411 endfunction | |
| 412 | |
| 413 This is just a simplistic example that results in a tab pages line that | |
| 414 resembles the default, but without adding a + for a modified buffer or | |
| 1118 | 415 truncating the names. You will want to reduce the width of labels in a |
| 678 | 416 clever way when there is not enough room. Check the 'columns' option for the |
| 681 | 417 space available. |
| 674 | 418 |
| 686 | 419 ============================================================================== |
| 420 5. Setting 'guitablabel' *setting-guitablabel* | |
| 421 | |
| 422 When the GUI tab pages line is displayed, 'guitablabel' can be used to | |
| 423 specify the label to display for each tab page. Unlike 'tabline', which | |
| 424 specifies the whole tab pages line at once, 'guitablabel' is used for each | |
| 425 label separately. | |
| 426 | |
| 839 | 427 'guitabtooltip' is very similar and is used for the tooltip of the same label. |
| 428 This only appears when the mouse pointer hovers over the label, thus it | |
| 429 usually is longer. Only supported on some systems though. | |
| 430 | |
| 686 | 431 See the 'statusline' option for the format of the value. |
| 432 | |
| 433 The "%N" item can be used for the current tab page number. The |v:lnum| | |
| 839 | 434 variable is also set to this number when the option is evaluated. |
| 690 | 435 The items that use a file name refer to the current window of the tab page. |
| 686 | 436 |
| 839 | 437 Note that syntax highlighting is not used for the option. The %T and %X |
| 690 | 438 items are also ignored. |
| 686 | 439 |
| 690 | 440 A simple example that puts the tab page number and the buffer name in the |
| 441 label: > | |
| 686 | 442 :set guitablabel=%N\ %f |
| 443 | |
| 839 | 444 An example that resembles the default 'guitablabel': Show the number of |
| 1118 | 445 windows in the tab page and a '+' if there is a modified buffer: > |
| 686 | 446 |
| 690 | 447 function GuiTabLabel() |
| 686 | 448 let label = '' |
| 449 let bufnrlist = tabpagebuflist(v:lnum) | |
| 450 | |
| 451 " Add '+' if one of the buffers in the tab page is modified | |
| 452 for bufnr in bufnrlist | |
| 453 if getbufvar(bufnr, "&modified") | |
| 454 let label = '+' | |
| 455 break | |
| 456 endif | |
| 457 endfor | |
| 458 | |
| 459 " Append the number of windows in the tab page if more than one | |
| 460 let wincount = tabpagewinnr(v:lnum, '$') | |
| 461 if wincount > 1 | |
| 462 let label .= wincount | |
| 463 endif | |
| 464 if label != '' | |
| 465 let label .= ' ' | |
| 466 endif | |
| 467 | |
| 468 " Append the buffer name | |
| 469 return label . bufname(bufnrlist[tabpagewinnr(v:lnum) - 1]) | |
| 470 endfunction | |
| 690 | 471 |
| 686 | 472 set guitablabel=%{GuiTabLabel()} |
| 690 | 473 |
| 474 Note that the function must be defined before setting the option, otherwise | |
| 475 you get an error message for the function not being known. | |
| 476 | |
| 857 | 477 If you want to fall back to the default label, return an empty string. |
| 478 | |
| 479 If you want to show something specific for a tab page, you might want to use a | |
| 480 tab page local variable. |t:var| | |
| 481 | |
