| 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. |

95 Examples: > |
| 682 | 96 :tab split " opens current buffer in new tab page |
| 97 :tab help gt " opens tab page with help for "gt" | |
| 98 | |
| 820 | 99 CTRL-W gf Open a new tab page and edit the file name under the cursor. |
| 100 See |CTRL-W_gf|. | |
| 101 | |
| 839 | 102 CTRL-W gF Open a new tab page and edit the file name under the cursor |
| 103 and jump to the line number following the file name. | |
| 104 See |CTRL-W_gF|. | |
| 674 | 105 |
| 106 CLOSING A TAB PAGE: | |
| 107 | |
| 682 | 108 Closing the last window of a tab page closes the tab page too, unless there is |
| 109 only one tab page. | |
| 674 | 110 |
| 111 Using the mouse: If the tab page line is displayed you can click in the "X" at | |
| 682 | 112 the top right to close the current tab page. A custom |'tabline'| may show |
| 113 something else. | |
| 674 | 114 |
| 115 *:tabc* *:tabclose* | |
| 116 :tabc[lose][!] Close current tab page. | |
| 117 This command fails when: | |
| 118 - There is only one tab page on the screen. *E784* | |
| 119 - When 'hidden' is not set, [!] is not used, a buffer has | |
| 120 changes, and there is no other window on this buffer. | |
| 121 Changes to the buffer are not written and won't get lost, so | |
| 6398 | 122 this is a "safe" command. > |
| 123 :tabclose " close the current tab page | |
| 674 | 124 |
| 6398 | 125 :{count}tabc[lose][!] |
| 674 | 126 :tabc[lose][!] {count} |
| 3750 | 127 Close tab page {count}. Fails in the same way as `:tabclose` |
| 6398 | 128 above. > |
| 129 :-tabclose " close the previous tab page | |
| 130 :+tabclose " close the next tab page | |
| 131 :1tabclose " close the first tab page | |
| 132 :$tabclose " close the last tab page | |
| 133 < | |
| 674 | 134 *:tabo* *:tabonly* |
| 135 :tabo[nly][!] Close all other tab pages. | |
| 136 When the 'hidden' option is set, all buffers in closed windows | |
| 137 become hidden. | |
| 138 When 'hidden' is not set, and the 'autowrite' option is set, | |
| 139 modified buffers are written. Otherwise, windows that have | |
| 140 buffers that are modified are not removed, unless the [!] is | |
| 141 given, then they become hidden. But modified buffers are | |
| 6398 | 142 never abandoned, so changes cannot get lost. > |
| 143 :tabonly " close all tab pages except the current | |
| 144 | |
| 145 :{count}tabo[nly][!] | |
| 146 Close all tab pages except the {count}th one. > | |
| 147 :.tabonly " one | |
| 148 :-tabonly " close all tab pages except the previous | |
| 149 " one | |
| 150 :+tabonly " close all tab pages except the next one | |
| 151 :1tabonly " close all tab pages except the first one | |
| 152 :$tabonly " close all tab pages except the last one | |
| 674 | 153 |
| 154 | |
| 155 SWITCHING TO ANOTHER TAB PAGE: | |
| 156 | |
| 157 Using the mouse: If the tab page line is displayed you can click in a tab page | |
| 682 | 158 label to switch to that tab page. Click where there is no label to go to the |
| 159 next tab page. |'tabline'| | |
| 674 | 160 |
| 819 | 161 :tabn[ext] *:tabn* *:tabnext* *gt* |
| 1118 | 162 <C-PageDown> *CTRL-<PageDown>* *<C-PageDown>* |
| 163 gt *i_CTRL-<PageDown>* *i_<C-PageDown>* | |
| 828 | 164 Go to the next tab page. Wraps around from the last to the |
| 674 | 165 first one. |
| 166 | |
| 1118 | 167 :tabn[ext] {count} |
| 168 {count}<C-PageDown> | |
| 169 {count}gt Go to tab page {count}. The first tab page has number one. | |
| 674 | 170 |
| 171 | |
| 1118 | 172 :tabp[revious] *:tabp* *:tabprevious* *gT* *:tabN* |
| 173 :tabN[ext] *:tabNext* *CTRL-<PageUp>* | |
| 174 <C-PageUp> *<C-PageUp>* *i_CTRL-<PageUp>* *i_<C-PageUp>* | |
| 682 | 175 gT Go to the previous tab page. Wraps around from the first one |
| 176 to the last one. | |
| 177 | |
| 178 :tabp[revious] {count} | |
| 179 :tabN[ext] {count} | |
| 1118 | 180 {count}<C-PageUp> |
| 682 | 181 {count}gT Go {count} tab pages back. Wraps around from the first one |
| 182 to the last one. | |
| 183 | |
| 685 | 184 :tabr[ewind] *:tabfir* *:tabfirst* *:tabr* *:tabrewind* |
| 686 | 185 :tabfir[st] Go to the first tab page. |
| 685 | 186 |
| 187 *:tabl* *:tablast* | |
| 188 :tabl[ast] Go to the last tab page. | |
| 189 | |
| 682 | 190 |
| 674 | 191 Other commands: |
| 192 *:tabs* | |
| 682 | 193 :tabs List the tab pages and the windows they contain. |
| 194 Shows a ">" for the current window. | |
| 195 Shows a "+" for modified buffers. | |
| 196 | |
| 197 | |
| 198 REORDERING TAB PAGES: | |
| 199 | |
| 843 | 200 :tabm[ove] [N] *:tabm* *:tabmove* |
| 3662 | 201 :[N]tabm[ove] |
| 843 | 202 Move the current tab page to after tab page N. Use zero to |
| 682 | 203 make the current tab page the first one. Without N the tab |
| 6398 | 204 page is made the last one. > |
| 205 :-tabmove " move the tab page to the left | |
| 206 :tabmove " move the tab page to the right | |
| 207 :.tabmove " as above | |
| 208 :+tabmove " as above | |
| 6474 | 209 :0tabmove " move the tab page to the beginning of the tab |
| 6398 | 210 " list |
| 211 :$tabmove " move the tab page to the end of the tab list | |
| 212 < | |
| 674 | 213 |
| 3662 | 214 :tabm[ove] +[N] |
| 215 :tabm[ove] -[N] | |
| 216 Move the current tab page N places to the right (with +) or to | |
| 217 the left (with -). | |
| 218 | |
| 219 Note that although it is possible to move a tab behind the N-th one by using | |
| 220 :Ntabmove, it is impossible to move it by N places by using :+Ntabmove. For | |
| 221 clarification what +N means in this context see |[range]|. | |
| 222 | |
| 685 | 223 |
| 224 LOOPING OVER TAB PAGES: | |
| 225 | |
| 226 *:tabd* *:tabdo* | |
| 6474 | 227 :[range]tabd[o] {cmd} |
| 228 Execute {cmd} in each tab page or if [range] is given only in | |
| 229 tab pages which tab page number is in the [range]. It works | |
| 230 like doing this: > | |
| 685 | 231 :tabfirst |
| 232 :{cmd} | |
| 233 :tabnext | |
| 234 :{cmd} | |
| 235 etc. | |
| 236 < This only operates in the current window of each tab page. | |
| 237 When an error is detected on one tab page, further tab pages | |
| 238 will not be visited. | |
| 239 The last tab page (or where an error occurred) becomes the | |
| 240 current tab page. | |
| 241 {cmd} can contain '|' to concatenate several commands. | |
| 242 {cmd} must not open or close tab pages or reorder them. | |
| 243 {not in Vi} {not available when compiled without the | |
| 244 |+listcmds| feature} | |
| 245 Also see |:windo|, |:argdo| and |:bufdo|. | |
| 246 | |
| 674 | 247 ============================================================================== |
| 248 3. Other items *tab-page-other* | |
| 249 | |
| 706 | 250 *tabline-menu* |
| 251 The GUI tab pages line has a popup menu. It is accessed with a right click. | |
| 252 The entries are: | |
| 253 Close Close the tab page under the mouse pointer. The | |
| 254 current one if there is no label under the mouse | |
| 255 pointer. | |
| 256 New Tab Open a tab page, editing an empty buffer. It appears | |
| 257 to the left of the mouse pointer. | |
| 1118 | 258 Open Tab... Like "New Tab" and additionally use a file selector to |
| 706 | 259 select a file to edit. |
| 260 | |
| 674 | 261 Diff mode works per tab page. You can see the diffs between several files |
| 262 within one tab page. Other tab pages can show differences between other | |
| 263 files. | |
| 264 | |
| 819 | 265 Variables local to a tab page start with "t:". |tabpage-variable| |
| 266 | |
| 824 | 267 Currently there is only one option local to a tab page: 'cmdheight'. |
| 268 | |
| 675 | 269 The TabLeave and TabEnter autocommand events can be used to do something when |
| 270 switching from one tab page to another. The exact order depends on what you | |
| 271 are doing. When creating a new tab page this works as if you create a new | |
| 272 window on the same buffer and then edit another buffer. Thus ":tabnew" | |
| 273 triggers: | |
| 274 WinLeave leave current window | |
| 275 TabLeave leave current tab page | |
| 6474 | 276 WinEnter enter window in new tab page |
| 675 | 277 TabEnter enter new tab page |
| 278 BufLeave leave current buffer | |
| 279 BufEnter enter new empty buffer | |
| 280 | |
| 678 | 281 When switching to another tab page the order is: |
| 675 | 282 BufLeave |
| 283 WinLeave | |
| 284 TabLeave | |
| 285 TabEnter | |
| 286 WinEnter | |
| 287 BufEnter | |
| 674 | 288 |
| 678 | 289 ============================================================================== |
| 290 4. Setting 'tabline' *setting-tabline* | |
| 291 | |
| 686 | 292 The 'tabline' option specifies what the line with tab pages labels looks like. |
| 293 It is only used when there is no GUI tab line. | |
| 294 | |
| 678 | 295 You can use the 'showtabline' option to specify when you want the line with |
| 296 tab page labels to appear: never, when there is more than one tab page or | |
| 297 always. | |
| 298 | |
| 299 The highlighting of the tab pages line is set with the groups TabLine | |
| 300 TabLineSel and TabLineFill. |hl-TabLine| |hl-TabLineSel| |hl-TabLineFill| | |
| 301 | |
| 1118 | 302 A "+" will be shown for a tab page that has a modified window. The number of |
| 303 windows in a tabpage is also shown. Thus "3+" means three windows and one of | |
| 304 them has a modified buffer. | |
| 305 | |
| 678 | 306 The 'tabline' option allows you to define your preferred way to tab pages |
| 307 labels. This isn't easy, thus an example will be given here. | |
| 308 | |
| 309 For basics see the 'statusline' option. The same items can be used in the | |
| 310 'tabline' option. Additionally, the |tabpagebuflist()|, |tabpagenr()| and | |
| 311 |tabpagewinnr()| functions are useful. | |
| 312 | |
| 1118 | 313 Since the number of tab labels will vary, you need to use an expression for |
| 314 the whole option. Something like: > | |
| 678 | 315 :set tabline=%!MyTabLine() |
| 316 | |
| 317 Then define the MyTabLine() function to list all the tab pages labels. A | |
| 318 convenient method is to split it in two parts: First go over all the tab | |
| 319 pages and define labels for them. Then get the label for each tab page. > | |
| 320 | |
| 321 function MyTabLine() | |
| 322 let s = '' | |
| 323 for i in range(tabpagenr('$')) | |
| 681 | 324 " select the highlighting |
| 678 | 325 if i + 1 == tabpagenr() |
| 326 let s .= '%#TabLineSel#' | |
| 327 else | |
| 328 let s .= '%#TabLine#' | |
| 329 endif | |
| 681 | 330 |
| 331 " set the tab page number (for mouse clicks) | |
| 332 let s .= '%' . (i + 1) . 'T' | |
| 333 | |
| 334 " the label is made by MyTabLabel() | |
| 678 | 335 let s .= ' %{MyTabLabel(' . (i + 1) . ')} ' |
| 336 endfor | |
| 681 | 337 |
| 338 " after the last tab fill with TabLineFill and reset tab page nr | |
| 339 let s .= '%#TabLineFill#%T' | |
| 340 | |
| 341 " right-align the label to close the current tab page | |
| 342 if tabpagenr('$') > 1 | |
| 343 let s .= '%=%#TabLine#%999Xclose' | |
| 344 endif | |
| 345 | |
| 678 | 346 return s |
| 347 endfunction | |
| 348 | |
| 349 Now the MyTabLabel() function is called for each tab page to get its label. > | |
| 350 | |
| 351 function MyTabLabel(n) | |
| 352 let buflist = tabpagebuflist(a:n) | |
| 353 let winnr = tabpagewinnr(a:n) | |
| 354 return bufname(buflist[winnr - 1]) | |
| 355 endfunction | |
| 356 | |
| 357 This is just a simplistic example that results in a tab pages line that | |
| 358 resembles the default, but without adding a + for a modified buffer or | |
| 1118 | 359 truncating the names. You will want to reduce the width of labels in a |
| 678 | 360 clever way when there is not enough room. Check the 'columns' option for the |
| 681 | 361 space available. |
| 674 | 362 |
| 686 | 363 ============================================================================== |
| 364 5. Setting 'guitablabel' *setting-guitablabel* | |
| 365 | |
| 366 When the GUI tab pages line is displayed, 'guitablabel' can be used to | |
| 367 specify the label to display for each tab page. Unlike 'tabline', which | |
| 368 specifies the whole tab pages line at once, 'guitablabel' is used for each | |
| 369 label separately. | |
| 370 | |
| 839 | 371 'guitabtooltip' is very similar and is used for the tooltip of the same label. |
| 372 This only appears when the mouse pointer hovers over the label, thus it | |
| 373 usually is longer. Only supported on some systems though. | |
| 374 | |
| 686 | 375 See the 'statusline' option for the format of the value. |
| 376 | |
| 377 The "%N" item can be used for the current tab page number. The |v:lnum| | |
| 839 | 378 variable is also set to this number when the option is evaluated. |
| 690 | 379 The items that use a file name refer to the current window of the tab page. |
| 686 | 380 |
| 839 | 381 Note that syntax highlighting is not used for the option. The %T and %X |
| 690 | 382 items are also ignored. |

| 690 | 384 A simple example that puts the tab page number and the buffer name in the |
| 385 label: > | |
| 686 | 386 :set guitablabel=%N\ %f |
| 387 | |
| 839 | 388 An example that resembles the default 'guitablabel': Show the number of |
| 1118 | 389 windows in the tab page and a '+' if there is a modified buffer: > |
| 686 | 390 |
| 690 | 391 function GuiTabLabel() |
| 686 | 392 let label = '' |
| 393 let bufnrlist = tabpagebuflist(v:lnum) | |
| 394 | |
| 395 " Add '+' if one of the buffers in the tab page is modified | |
| 396 for bufnr in bufnrlist | |
| 397 if getbufvar(bufnr, "&modified") | |
| 398 let label = '+' | |
| 399 break | |
| 400 endif | |
| 401 endfor | |
| 402 | |
| 403 " Append the number of windows in the tab page if more than one | |
| 404 let wincount = tabpagewinnr(v:lnum, '$') | |
| 405 if wincount > 1 | |
| 406 let label .= wincount | |
| 407 endif | |
| 408 if label != '' | |
| 409 let label .= ' ' | |
| 410 endif | |
| 411 | |
| 412 " Append the buffer name | |
| 413 return label . bufname(bufnrlist[tabpagewinnr(v:lnum) - 1]) | |
| 414 endfunction | |
| 690 | 415 |
| 686 | 416 set guitablabel=%{GuiTabLabel()} |
| 690 | 417 |
| 418 Note that the function must be defined before setting the option, otherwise | |
| 419 you get an error message for the function not being known. | |
| 420 | |
| 857 | 421 If you want to fall back to the default label, return an empty string. |
| 422 | |
| 423 If you want to show something specific for a tab page, you might want to use a | |
| 424 tab page local variable. |t:var| | |
