| 23 ============================================================================== | |
| 24 1. Introduction *tab-page-intro* | |
| 25 | |
| 26 A tab page holds one or more windows. You can easily switch between tab | |
| 27 pages, so that you have several collections of windows to work on different | |
| 28 things. | |
| 29 | |
| 30 Usually you will see a list of labels at the top of the Vim window, one for | |
| 31 each tab page. With the mouse you can click on the label to jump to that tab | |
| 32 page. There are other ways to move between tab pages, see below. | |
| 33 | |
| 34 Most commands work only in the current tab page. That includes the |CTRL-W| | |
| 698 | 35 commands, |:windo|, |:all| and |:ball| (when not using the |:tab| modifier). |
| 36 The commands that are aware of other tab pages than the current one are | |
| 37 mentioned below. | |
| 674 | 38 |
| 39 Tabs are also a nice way to edit a buffer temporarily without changing the | |
| 40 current window layout. Open a new tab page, do whatever you want to do and | |
| 41 close the tab page. | |
| 42 | |
| 43 ============================================================================== | |
| 44 2. Commands *tab-page-commands* | |

49 tab page (up to 'tabpagemax'). See |-p| |
| 674 | 50 |
| 706 | 51 A double click with the mouse in the non-GUI tab pages line opens a new, empty |
| 52 tab page. It is placed left of the position of the click. The first click | |
| 53 may select another tab page first, causing an extra screen update. | |
| 54 | |
| 844 | 55 This also works in a few GUI versions, esp. Win32 and Motif. But only when |
| 56 clicking right of the labels. | |
| 57 | |
| 706 | 58 In the GUI tab pages line you can use the right mouse button to open menu. |

| 115 CLOSING A TAB PAGE: | |
| 116 | |
| 682 | 117 Closing the last window of a tab page closes the tab page too, unless there is |
| 118 only one tab page. | |
| 674 | 119 |
| 120 Using the mouse: If the tab page line is displayed you can click in the "X" at | |
| 682 | 121 the top right to close the current tab page. A custom |'tabline'| may show |
| 122 something else. | |
| 674 | 123 |
| 124 *:tabc* *:tabclose* | |
| 125 :tabc[lose][!] Close current tab page. | |
| 126 This command fails when: | |
| 127 - There is only one tab page on the screen. *E784* | |
| 128 - When 'hidden' is not set, [!] is not used, a buffer has | |
| 129 changes, and there is no other window on this buffer. | |
| 130 Changes to the buffer are not written and won't get lost, so | |
| 6398 | 131 this is a "safe" command. > |
| 132 :tabclose " close the current tab page | |
| 674 | 133 |
| 6398 | 134 :{count}tabc[lose][!] |
| 674 | 135 :tabc[lose][!] {count} |
| 3750 | 136 Close tab page {count}. Fails in the same way as `:tabclose` |
| 6398 | 137 above. > |
| 138 :-tabclose " close the previous tab page | |
| 139 :+tabclose " close the next tab page | |

| 146 become hidden. | |
| 147 When 'hidden' is not set, and the 'autowrite' option is set, | |
| 148 modified buffers are written. Otherwise, windows that have | |
| 149 buffers that are modified are not removed, unless the [!] is | |
| 150 given, then they become hidden. But modified buffers are | |
| 6398 | 151 never abandoned, so changes cannot get lost. > |

| 250 Execute {cmd} in each tab page or if [range] is given only in | |
| 251 tab pages which tab page number is in the [range]. It works | |
| 252 like doing this: > | |
| 685 | 253 :tabfirst |
| 254 :{cmd} | |
| 255 :tabnext | |
| 256 :{cmd} | |
| 257 etc. | |
| 258 < This only operates in the current window of each tab page. | |
| 259 When an error is detected on one tab page, further tab pages | |
| 260 will not be visited. | |
| 261 The last tab page (or where an error occurred) becomes the | |
| 262 current tab page. | |
| 263 {cmd} can contain '|' to concatenate several commands. | |
| 264 {cmd} must not open or close tab pages or reorder them. | |
| 265 {not in Vi} {not available when compiled without the | |
| 266 |+listcmds| feature} | |

| 271 3. Other items *tab-page-other* | |
| 272 | |
| 706 | 273 *tabline-menu* |
| 274 The GUI tab pages line has a popup menu. It is accessed with a right click. | |
| 275 The entries are: | |
| 276 Close Close the tab page under the mouse pointer. The | |
| 277 current one if there is no label under the mouse | |
| 278 pointer. | |
| 279 New Tab Open a tab page, editing an empty buffer. It appears | |
| 280 to the left of the mouse pointer. | |
| 1118 | 281 Open Tab... Like "New Tab" and additionally use a file selector to |
| 706 | 282 select a file to edit. |
| 283 | |
| 674 | 284 Diff mode works per tab page. You can see the diffs between several files |
| 285 within one tab page. Other tab pages can show differences between other | |
| 286 files. | |
| 287 | |
| 819 | 288 Variables local to a tab page start with "t:". |tabpage-variable| |
| 289 | |
| 824 | 290 Currently there is only one option local to a tab page: 'cmdheight'. |

292 *tabnew-autocmd* |
| 675 | 293 The TabLeave and TabEnter autocommand events can be used to do something when |
| 294 switching from one tab page to another. The exact order depends on what you | |
| 295 are doing. When creating a new tab page this works as if you create a new | |
| 296 window on the same buffer and then edit another buffer. Thus ":tabnew" | |
| 297 triggers: | |
| 298 WinLeave leave current window | |
| 299 TabLeave leave current tab page | |
| 6474 | 300 WinEnter enter window in new tab page |
| 675 | 301 TabEnter enter new tab page |
| 302 BufLeave leave current buffer | |
| 303 BufEnter enter new empty buffer | |
| 304 | |
| 678 | 305 When switching to another tab page the order is: |
| 675 | 306 BufLeave |
| 307 WinLeave | |
| 308 TabLeave | |
| 309 TabEnter | |
| 310 WinEnter | |
| 311 BufEnter | |
| 674 | 312 |
| 678 | 313 ============================================================================== |
| 314 4. Setting 'tabline' *setting-tabline* | |
| 315 | |
| 686 | 316 The 'tabline' option specifies what the line with tab pages labels looks like. |
| 317 It is only used when there is no GUI tab line. | |
| 318 | |
| 678 | 319 You can use the 'showtabline' option to specify when you want the line with |
| 320 tab page labels to appear: never, when there is more than one tab page or | |
| 321 always. | |
| 322 | |
| 323 The highlighting of the tab pages line is set with the groups TabLine | |
| 324 TabLineSel and TabLineFill. |hl-TabLine| |hl-TabLineSel| |hl-TabLineFill| | |
| 325 | |
| 1118 | 326 A "+" will be shown for a tab page that has a modified window. The number of |
| 327 windows in a tabpage is also shown. Thus "3+" means three windows and one of | |
| 328 them has a modified buffer. | |
| 329 | |
| 678 | 330 The 'tabline' option allows you to define your preferred way to tab pages |
| 331 labels. This isn't easy, thus an example will be given here. | |
| 332 | |
| 333 For basics see the 'statusline' option. The same items can be used in the | |
| 334 'tabline' option. Additionally, the |tabpagebuflist()|, |tabpagenr()| and | |
| 335 |tabpagewinnr()| functions are useful. | |
| 336 | |
| 1118 | 337 Since the number of tab labels will vary, you need to use an expression for |
| 338 the whole option. Something like: > | |
| 678 | 339 :set tabline=%!MyTabLine() |
| 340 | |
| 341 Then define the MyTabLine() function to list all the tab pages labels. A | |
| 342 convenient method is to split it in two parts: First go over all the tab | |
| 343 pages and define labels for them. Then get the label for each tab page. > | |
| 344 | |
| 345 function MyTabLine() | |
| 346 let s = '' | |
| 347 for i in range(tabpagenr('$')) | |
| 681 | 348 " select the highlighting |
| 678 | 349 if i + 1 == tabpagenr() |
| 350 let s .= '%#TabLineSel#' | |
| 351 else | |
| 352 let s .= '%#TabLine#' | |
| 353 endif | |
| 681 | 354 |
| 355 " set the tab page number (for mouse clicks) | |
| 356 let s .= '%' . (i + 1) . 'T' | |
| 357 | |
| 358 " the label is made by MyTabLabel() | |
| 678 | 359 let s .= ' %{MyTabLabel(' . (i + 1) . ')} ' |
| 360 endfor | |
| 681 | 361 |
| 362 " after the last tab fill with TabLineFill and reset tab page nr | |
| 363 let s .= '%#TabLineFill#%T' | |
| 364 | |
| 365 " right-align the label to close the current tab page | |
| 366 if tabpagenr('$') > 1 | |
| 367 let s .= '%=%#TabLine#%999Xclose' | |
| 368 endif | |
| 369 | |
| 678 | 370 return s |
| 371 endfunction | |
| 372 | |
| 373 Now the MyTabLabel() function is called for each tab page to get its label. > | |
| 374 | |
| 375 function MyTabLabel(n) | |
| 376 let buflist = tabpagebuflist(a:n) | |
| 377 let winnr = tabpagewinnr(a:n) | |
| 378 return bufname(buflist[winnr - 1]) | |
| 379 endfunction | |
| 380 | |
| 381 This is just a simplistic example that results in a tab pages line that | |
| 382 resembles the default, but without adding a + for a modified buffer or | |
| 1118 | 383 truncating the names. You will want to reduce the width of labels in a |
| 678 | 384 clever way when there is not enough room. Check the 'columns' option for the |
| 681 | 385 space available. |
| 674 | 386 |
| 686 | 387 ============================================================================== |
| 388 5. Setting 'guitablabel' *setting-guitablabel* | |
| 389 | |
| 390 When the GUI tab pages line is displayed, 'guitablabel' can be used to | |
| 391 specify the label to display for each tab page. Unlike 'tabline', which | |
| 392 specifies the whole tab pages line at once, 'guitablabel' is used for each | |
| 393 label separately. | |
| 394 | |
| 839 | 395 'guitabtooltip' is very similar and is used for the tooltip of the same label. |
| 396 This only appears when the mouse pointer hovers over the label, thus it | |
| 397 usually is longer. Only supported on some systems though. | |
| 398 | |
| 686 | 399 See the 'statusline' option for the format of the value. |
| 400 | |
| 401 The "%N" item can be used for the current tab page number. The |v:lnum| | |
| 839 | 402 variable is also set to this number when the option is evaluated. |
| 690 | 403 The items that use a file name refer to the current window of the tab page. |
| 686 | 404 |
| 839 | 405 Note that syntax highlighting is not used for the option. The %T and %X |
| 690 | 406 items are also ignored. |
| 686 | 407 |
| 690 | 408 A simple example that puts the tab page number and the buffer name in the |
| 409 label: > | |
| 686 | 410 :set guitablabel=%N\ %f |
| 411 | |
| 839 | 412 An example that resembles the default 'guitablabel': Show the number of |
| 1118 | 413 windows in the tab page and a '+' if there is a modified buffer: > |
| 686 | 414 |
| 690 | 415 function GuiTabLabel() |
| 686 | 416 let label = '' |
| 417 let bufnrlist = tabpagebuflist(v:lnum) | |
| 418 | |
| 419 " Add '+' if one of the buffers in the tab page is modified | |
| 420 for bufnr in bufnrlist | |
| 421 if getbufvar(bufnr, "&modified") | |
| 422 let label = '+' | |
| 423 break | |
| 424 endif | |
| 425 endfor | |
| 426 | |
| 427 " Append the number of windows in the tab page if more than one | |
| 428 let wincount = tabpagewinnr(v:lnum, '$') | |
| 429 if wincount > 1 | |
| 430 let label .= wincount | |
| 431 endif | |
| 432 if label != '' | |
| 433 let label .= ' ' | |
| 434 endif | |
| 435 | |
| 436 " Append the buffer name | |
| 437 return label . bufname(bufnrlist[tabpagewinnr(v:lnum) - 1]) | |
| 438 endfunction | |
| 690 | 439 |
| 686 | 440 set guitablabel=%{GuiTabLabel()} |
| 690 | 441 |
| 442 Note that the function must be defined before setting the option, otherwise | |
| 443 you get an error message for the function not being known. | |
| 444 | |
| 857 | 445 If you want to fall back to the default label, return an empty string. |
| 446 | |
| 447 If you want to show something specific for a tab page, you might want to use a | |
| 448 tab page local variable. |t:var| | |
| 449 | |
