updated for version 7.3.398
Problem: When creating more than 10 location lists and adding items one by
one a previous location may be used. (Audrius Ka?ukauskas)

| 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 | |

86 Examples: > |
| 682 | 87 :tab split " opens current buffer in new tab page |
| 88 :tab help gt " opens tab page with help for "gt" | |
| 89 | |
| 820 | 90 CTRL-W gf Open a new tab page and edit the file name under the cursor. |
| 91 See |CTRL-W_gf|. | |
| 92 | |
| 839 | 93 CTRL-W gF Open a new tab page and edit the file name under the cursor |
| 94 and jump to the line number following the file name. | |
| 95 See |CTRL-W_gF|. | |
| 674 | 96 |
| 97 CLOSING A TAB PAGE: | |
| 98 | |
| 682 | 99 Closing the last window of a tab page closes the tab page too, unless there is |
| 100 only one tab page. | |
| 674 | 101 |
| 102 Using the mouse: If the tab page line is displayed you can click in the "X" at | |
| 682 | 103 the top right to close the current tab page. A custom |'tabline'| may show |
| 104 something else. | |
| 674 | 105 |
| 106 *:tabc* *:tabclose* | |
| 107 :tabc[lose][!] Close current tab page. | |
| 108 This command fails when: | |
| 109 - There is only one tab page on the screen. *E784* | |
| 110 - When 'hidden' is not set, [!] is not used, a buffer has | |
| 111 changes, and there is no other window on this buffer. | |
| 112 Changes to the buffer are not written and won't get lost, so | |
| 113 this is a "safe" command. | |
| 114 | |
| 115 :tabc[lose][!] {count} | |
| 116 Close tab page {count}. Fails in the same way as ':tabclose" | |
| 117 above. | |
| 118 | |
| 119 *:tabo* *:tabonly* | |
| 120 :tabo[nly][!] Close all other tab pages. | |
| 121 When the 'hidden' option is set, all buffers in closed windows | |
| 122 become hidden. | |
| 123 When 'hidden' is not set, and the 'autowrite' option is set, | |
| 124 modified buffers are written. Otherwise, windows that have | |
| 125 buffers that are modified are not removed, unless the [!] is | |
| 126 given, then they become hidden. But modified buffers are | |
| 127 never abandoned, so changes cannot get lost. | |
| 128 | |
| 129 | |
| 130 SWITCHING TO ANOTHER TAB PAGE: | |
| 131 | |
| 132 Using the mouse: If the tab page line is displayed you can click in a tab page | |
| 682 | 133 label to switch to that tab page. Click where there is no label to go to the |
| 134 next tab page. |'tabline'| | |
| 674 | 135 |
| 819 | 136 :tabn[ext] *:tabn* *:tabnext* *gt* |
| 1118 | 137 <C-PageDown> *CTRL-<PageDown>* *<C-PageDown>* |
| 138 gt *i_CTRL-<PageDown>* *i_<C-PageDown>* | |
| 828 | 139 Go to the next tab page. Wraps around from the last to the |
| 674 | 140 first one. |
| 141 | |
| 1118 | 142 :tabn[ext] {count} |
| 143 {count}<C-PageDown> | |
| 144 {count}gt Go to tab page {count}. The first tab page has number one. | |
| 674 | 145 |
| 146 | |
| 1118 | 147 :tabp[revious] *:tabp* *:tabprevious* *gT* *:tabN* |
| 148 :tabN[ext] *:tabNext* *CTRL-<PageUp>* | |
| 149 <C-PageUp> *<C-PageUp>* *i_CTRL-<PageUp>* *i_<C-PageUp>* | |
| 682 | 150 gT Go to the previous tab page. Wraps around from the first one |
| 151 to the last one. | |
| 152 | |
| 153 :tabp[revious] {count} | |
| 154 :tabN[ext] {count} | |
| 1118 | 155 {count}<C-PageUp> |
| 682 | 156 {count}gT Go {count} tab pages back. Wraps around from the first one |
| 157 to the last one. | |
| 158 | |
| 685 | 159 :tabr[ewind] *:tabfir* *:tabfirst* *:tabr* *:tabrewind* |
| 686 | 160 :tabfir[st] Go to the first tab page. |
| 685 | 161 |
| 162 *:tabl* *:tablast* | |
| 163 :tabl[ast] Go to the last tab page. | |
| 164 | |
| 682 | 165 |
| 674 | 166 Other commands: |
| 167 *:tabs* | |
| 682 | 168 :tabs List the tab pages and the windows they contain. |
| 169 Shows a ">" for the current window. | |
| 170 Shows a "+" for modified buffers. | |
| 171 | |
| 172 | |
| 173 REORDERING TAB PAGES: | |
| 174 | |
| 843 | 175 :tabm[ove] [N] *:tabm* *:tabmove* |
| 176 Move the current tab page to after tab page N. Use zero to | |
| 682 | 177 make the current tab page the first one. Without N the tab |
| 178 page is made the last one. | |
| 674 | 179 |
| 685 | 180 |
| 181 LOOPING OVER TAB PAGES: | |
| 182 | |
| 183 *:tabd* *:tabdo* | |
| 184 :tabd[o] {cmd} Execute {cmd} in each tab page. | |
| 185 It works like doing this: > | |
| 186 :tabfirst | |
| 187 :{cmd} | |
| 188 :tabnext | |
| 189 :{cmd} | |
| 190 etc. | |
| 191 < This only operates in the current window of each tab page. | |
| 192 When an error is detected on one tab page, further tab pages | |
| 193 will not be visited. | |
| 194 The last tab page (or where an error occurred) becomes the | |
| 195 current tab page. | |
| 196 {cmd} can contain '|' to concatenate several commands. | |
| 197 {cmd} must not open or close tab pages or reorder them. | |
| 198 {not in Vi} {not available when compiled without the | |
| 199 |+listcmds| feature} | |
| 200 Also see |:windo|, |:argdo| and |:bufdo|. | |
| 201 | |
| 674 | 202 ============================================================================== |
| 203 3. Other items *tab-page-other* | |
| 204 | |
| 706 | 205 *tabline-menu* |
| 206 The GUI tab pages line has a popup menu. It is accessed with a right click. | |
| 207 The entries are: | |
| 208 Close Close the tab page under the mouse pointer. The | |
| 209 current one if there is no label under the mouse | |
| 210 pointer. | |
| 211 New Tab Open a tab page, editing an empty buffer. It appears | |
| 212 to the left of the mouse pointer. | |
| 1118 | 213 Open Tab... Like "New Tab" and additionally use a file selector to |
| 706 | 214 select a file to edit. |
| 215 | |
| 674 | 216 Diff mode works per tab page. You can see the diffs between several files |
| 217 within one tab page. Other tab pages can show differences between other | |
| 218 files. | |
| 219 | |
| 819 | 220 Variables local to a tab page start with "t:". |tabpage-variable| |
| 221 | |
| 824 | 222 Currently there is only one option local to a tab page: 'cmdheight'. |
| 223 | |
| 675 | 224 The TabLeave and TabEnter autocommand events can be used to do something when |
| 225 switching from one tab page to another. The exact order depends on what you | |
| 226 are doing. When creating a new tab page this works as if you create a new | |
| 227 window on the same buffer and then edit another buffer. Thus ":tabnew" | |
| 228 triggers: | |
| 229 WinLeave leave current window | |
| 230 TabLeave leave current tab page | |
| 231 TabEnter enter new tab page | |
| 232 WinEnter enter window in new tab page | |
| 233 BufLeave leave current buffer | |
| 234 BufEnter enter new empty buffer | |
| 235 | |
| 678 | 236 When switching to another tab page the order is: |
| 675 | 237 BufLeave |
| 238 WinLeave | |
| 239 TabLeave | |
| 240 TabEnter | |
| 241 WinEnter | |
| 242 BufEnter | |
| 674 | 243 |
| 678 | 244 ============================================================================== |
| 245 4. Setting 'tabline' *setting-tabline* | |
| 246 | |
| 686 | 247 The 'tabline' option specifies what the line with tab pages labels looks like. |
| 248 It is only used when there is no GUI tab line. | |
| 249 | |
| 678 | 250 You can use the 'showtabline' option to specify when you want the line with |
| 251 tab page labels to appear: never, when there is more than one tab page or | |
| 252 always. | |
| 253 | |
| 254 The highlighting of the tab pages line is set with the groups TabLine | |
| 255 TabLineSel and TabLineFill. |hl-TabLine| |hl-TabLineSel| |hl-TabLineFill| | |
| 256 | |
| 1118 | 257 A "+" will be shown for a tab page that has a modified window. The number of |
| 258 windows in a tabpage is also shown. Thus "3+" means three windows and one of | |
| 259 them has a modified buffer. | |
| 260 | |
| 678 | 261 The 'tabline' option allows you to define your preferred way to tab pages |
| 262 labels. This isn't easy, thus an example will be given here. | |
| 263 | |
| 264 For basics see the 'statusline' option. The same items can be used in the | |
| 265 'tabline' option. Additionally, the |tabpagebuflist()|, |tabpagenr()| and | |
| 266 |tabpagewinnr()| functions are useful. | |
| 267 | |
| 1118 | 268 Since the number of tab labels will vary, you need to use an expression for |
| 269 the whole option. Something like: > | |
| 678 | 270 :set tabline=%!MyTabLine() |
| 271 | |
| 272 Then define the MyTabLine() function to list all the tab pages labels. A | |
| 273 convenient method is to split it in two parts: First go over all the tab | |
| 274 pages and define labels for them. Then get the label for each tab page. > | |
| 275 | |
| 276 function MyTabLine() | |
| 277 let s = '' | |
| 278 for i in range(tabpagenr('$')) | |
| 681 | 279 " select the highlighting |
| 678 | 280 if i + 1 == tabpagenr() |
| 281 let s .= '%#TabLineSel#' | |
| 282 else | |
| 283 let s .= '%#TabLine#' | |
| 284 endif | |
| 681 | 285 |
| 286 " set the tab page number (for mouse clicks) | |
| 287 let s .= '%' . (i + 1) . 'T' | |
| 288 | |
| 289 " the label is made by MyTabLabel() | |
| 678 | 290 let s .= ' %{MyTabLabel(' . (i + 1) . ')} ' |
| 291 endfor | |
| 681 | 292 |
| 293 " after the last tab fill with TabLineFill and reset tab page nr | |
| 294 let s .= '%#TabLineFill#%T' | |
| 295 | |
| 296 " right-align the label to close the current tab page | |
| 297 if tabpagenr('$') > 1 | |
| 298 let s .= '%=%#TabLine#%999Xclose' | |
| 299 endif | |
| 300 | |
| 678 | 301 return s |
| 302 endfunction | |
| 303 | |
| 304 Now the MyTabLabel() function is called for each tab page to get its label. > | |
| 305 | |
| 306 function MyTabLabel(n) | |
| 307 let buflist = tabpagebuflist(a:n) | |
| 308 let winnr = tabpagewinnr(a:n) | |
| 309 return bufname(buflist[winnr - 1]) | |
| 310 endfunction | |
| 311 | |
| 312 This is just a simplistic example that results in a tab pages line that | |
| 313 resembles the default, but without adding a + for a modified buffer or | |
| 1118 | 314 truncating the names. You will want to reduce the width of labels in a |
| 678 | 315 clever way when there is not enough room. Check the 'columns' option for the |
| 681 | 316 space available. |
| 674 | 317 |
| 686 | 318 ============================================================================== |
| 319 5. Setting 'guitablabel' *setting-guitablabel* | |
| 320 | |
| 321 When the GUI tab pages line is displayed, 'guitablabel' can be used to | |
| 322 specify the label to display for each tab page. Unlike 'tabline', which | |
| 323 specifies the whole tab pages line at once, 'guitablabel' is used for each | |
| 324 label separately. | |
| 325 | |
| 839 | 326 'guitabtooltip' is very similar and is used for the tooltip of the same label. |
| 327 This only appears when the mouse pointer hovers over the label, thus it | |
| 328 usually is longer. Only supported on some systems though. | |
| 329 | |
| 686 | 330 See the 'statusline' option for the format of the value. |
| 331 | |
| 332 The "%N" item can be used for the current tab page number. The |v:lnum| | |
| 839 | 333 variable is also set to this number when the option is evaluated. |
| 690 | 334 The items that use a file name refer to the current window of the tab page. |
| 686 | 335 |
| 839 | 336 Note that syntax highlighting is not used for the option. The %T and %X |
| 690 | 337 items are also ignored. |
| 686 | 338 |
| 690 | 339 A simple example that puts the tab page number and the buffer name in the |
| 340 label: > | |
| 686 | 341 :set guitablabel=%N\ %f |
| 342 | |
| 839 | 343 An example that resembles the default 'guitablabel': Show the number of |
| 1118 | 344 windows in the tab page and a '+' if there is a modified buffer: > |
| 686 | 345 |
| 690 | 346 function GuiTabLabel() |
| 686 | 347 let label = '' |
| 348 let bufnrlist = tabpagebuflist(v:lnum) | |
| 349 | |
| 350 " Add '+' if one of the buffers in the tab page is modified | |
| 351 for bufnr in bufnrlist | |
| 352 if getbufvar(bufnr, "&modified") | |
| 353 let label = '+' | |
| 354 break | |
| 355 endif | |
| 356 endfor | |
| 357 | |
| 358 " Append the number of windows in the tab page if more than one | |
| 359 let wincount = tabpagewinnr(v:lnum, '$') | |
| 360 if wincount > 1 | |
| 361 let label .= wincount | |
| 362 endif | |
| 363 if label != '' | |
| 364 let label .= ' ' | |
| 365 endif | |
| 366 | |
| 367 " Append the buffer name | |
| 368 return label . bufname(bufnrlist[tabpagewinnr(v:lnum) - 1]) | |
| 369 endfunction | |
| 690 | 370 |
| 686 | 371 set guitablabel=%{GuiTabLabel()} |
