| 7 Syntax highlighting *syntax* *syntax-highlighting* *coloring* | |
| 8 | |
| 9 Syntax highlighting enables Vim to show parts of the text in another font or | |
| 10 color. Those parts can be specific keywords or text matching a pattern. Vim | |
| 11 doesn't parse the whole file (to keep it fast), so the highlighting has its | |
| 12 limitations. Lexical highlighting might be a better name, but since everybody | |
| 13 calls it syntax highlighting we'll stick with that. | |
| 14 | |
| 15 Vim supports syntax highlighting on all terminals. But since most ordinary | |
| 16 terminals have very limited highlighting possibilities, it works best in the | |
| 17 GUI version, gvim. | |
| 18 | |
| 19 In the User Manual: | |
| 20 |usr_06.txt| introduces syntax highlighting. | |
| 21 |usr_44.txt| introduces writing a syntax file. | |
| 22 | |

| 7 | 42 |
| 43 {Vi does not have any of these commands} | |
| 44 | |
| 45 Syntax highlighting is not available when the |+syntax| feature has been | |
| 46 disabled at compile time. | |
| 47 | |
| 48 ============================================================================== | |
| 49 1. Quick start *:syn-qstart* | |
| 50 | |
| 51 *:syn-enable* *:syntax-enable* | |
| 52 This command switches on syntax highlighting: > | |
| 53 | |
| 54 :syntax enable | |
| 55 | |
| 56 What this command actually does is to execute the command > | |
| 57 :source $VIMRUNTIME/syntax/syntax.vim | |
| 58 | |
| 59 If the VIM environment variable is not set, Vim will try to find | |
| 60 the path in another way (see |$VIMRUNTIME|). Usually this works just | |
| 61 fine. If it doesn't, try setting the VIM environment variable to the | |
| 62 directory where the Vim stuff is located. For example, if your syntax files | |
| 19116 | 63 are in the "/usr/vim/vim82/syntax" directory, set $VIMRUNTIME to |
| 64 "/usr/vim/vim82". You must do this in the shell, before starting Vim. | |

66 will start soon. See |'go-M'| about avoiding that. |
| 7 | 67 |
| 68 *:syn-on* *:syntax-on* | |
| 23305 | 69 The `:syntax enable` command will keep most of your current color settings. |
| 70 This allows using `:highlight` commands to set your preferred colors before or | |
| 7 | 71 after using this command. If you want Vim to overrule your settings with the |
| 72 defaults, use: > | |
| 73 :syntax on | |
| 74 < | |
| 75 *:hi-normal* *:highlight-normal* | |
| 76 If you are running in the GUI, you can get white text on a black background | |
| 77 with: > | |
| 78 :highlight Normal guibg=Black guifg=White | |
| 79 For a color terminal see |:hi-normal-cterm|. | |
| 80 For setting up your own colors syntax highlighting see |syncolor|. | |
| 81 | |
| 18972 | 82 NOTE: The syntax files on MS-Windows have lines that end in <CR><NL>. |
| 7 | 83 The files for Unix end in <NL>. This means you should use the right type of |
| 18972 | 84 file for your system. Although on MS-Windows the right format is |
| 7 | 85 automatically selected if the 'fileformats' option is not empty. |
| 86 | |
| 87 NOTE: When using reverse video ("gvim -fg white -bg black"), the default value | |
| 88 of 'background' will not be set until the GUI window is opened, which is after | |
| 819 | 89 reading the |gvimrc|. This will cause the wrong default highlighting to be |
| 7 | 90 used. To set the default value of 'background' before switching on |
| 819 | 91 highlighting, include the ":gui" command in the |gvimrc|: > |
| 7 | 92 |
| 93 :gui " open window and set default for 'background' | |
| 94 :syntax on " start highlighting, use 'background' to set colors | |
| 95 | |
| 819 | 96 NOTE: Using ":gui" in the |gvimrc| means that "gvim -f" won't start in the |
| 7 | 97 foreground! Use ":gui -f" then. |
| 98 | |
| 2520 | 99 *g:syntax_on* |
| 100 You can toggle the syntax on/off with this command: > | |
| 101 :if exists("g:syntax_on") | syntax off | else | syntax enable | endif | |
| 7 | 102 |
| 103 To put this into a mapping, you can use: > | |
| 2520 | 104 :map <F7> :if exists("g:syntax_on") <Bar> |
| 7 | 105 \ syntax off <Bar> |
| 106 \ else <Bar> | |
| 107 \ syntax enable <Bar> | |
| 108 \ endif <CR> | |
| 109 [using the |<>| notation, type this literally] | |
| 110 | |
| 1624 | 111 Details: |
| 7 | 112 The ":syntax" commands are implemented by sourcing a file. To see exactly how |
| 113 this works, look in the file: | |
| 114 command file ~ | |
| 115 :syntax enable $VIMRUNTIME/syntax/syntax.vim | |
| 116 :syntax on $VIMRUNTIME/syntax/syntax.vim | |
| 117 :syntax manual $VIMRUNTIME/syntax/manual.vim | |
| 118 :syntax off $VIMRUNTIME/syntax/nosyntax.vim | |
| 119 Also see |syntax-loading|. | |

| 125 2. Syntax files *:syn-files* | |
| 126 | |
| 127 The syntax and highlighting commands for one language are normally stored in | |
| 128 a syntax file. The name convention is: "{name}.vim". Where {name} is the | |
| 129 name of the language, or an abbreviation (to fit the name in 8.3 characters, | |
| 130 a requirement in case the file is used on a DOS filesystem). | |
| 131 Examples: | |
| 132 c.vim perl.vim java.vim html.vim | |
| 133 cpp.vim sh.vim csh.vim | |
| 134 | |
| 135 The syntax file can contain any Ex commands, just like a vimrc file. But | |
| 136 the idea is that only commands for a specific language are included. When a | |
| 137 language is a superset of another language, it may include the other one, | |
| 138 for example, the cpp.vim file could include the c.vim file: > | |
| 139 :so $VIMRUNTIME/syntax/c.vim | |
| 140 | |
| 141 The .vim files are normally loaded with an autocommand. For example: > | |
| 142 :au Syntax c runtime! syntax/c.vim | |
| 143 :au Syntax cpp runtime! syntax/cpp.vim | |
| 144 These commands are normally in the file $VIMRUNTIME/syntax/synload.vim. | |
| 145 | |
| 146 | |
| 147 MAKING YOUR OWN SYNTAX FILES *mysyntaxfile* | |
| 148 | |
| 149 When you create your own syntax files, and you want to have Vim use these | |
| 150 automatically with ":syntax enable", do this: | |
| 151 | |
| 152 1. Create your user runtime directory. You would normally use the first item | |
| 153 of the 'runtimepath' option. Example for Unix: > | |
| 154 mkdir ~/.vim | |
| 155 | |
| 156 2. Create a directory in there called "syntax". For Unix: > | |
| 157 mkdir ~/.vim/syntax | |
| 158 | |
| 159 3. Write the Vim syntax file. Or download one from the internet. Then write | |
| 160 it in your syntax directory. For example, for the "mine" syntax: > | |
| 161 :w ~/.vim/syntax/mine.vim | |
| 162 | |
| 163 Now you can start using your syntax file manually: > | |
| 164 :set syntax=mine | |
| 165 You don't have to exit Vim to use this. | |
| 166 | |
| 167 If you also want Vim to detect the type of file, see |new-filetype|. | |
| 168 | |
| 169 If you are setting up a system with many users and you don't want each user | |
| 170 to add the same syntax file, you can use another directory from 'runtimepath'. | |
| 171 | |
| 172 | |
| 173 ADDING TO AN EXISTING SYNTAX FILE *mysyntaxfile-add* | |
| 174 | |
| 175 If you are mostly satisfied with an existing syntax file, but would like to | |
| 176 add a few items or change the highlighting, follow these steps: | |
| 177 | |
| 178 1. Create your user directory from 'runtimepath', see above. | |
| 179 | |
| 180 2. Create a directory in there called "after/syntax". For Unix: > | |
| 181 mkdir ~/.vim/after | |
| 182 mkdir ~/.vim/after/syntax | |
| 183 | |
| 184 3. Write a Vim script that contains the commands you want to use. For | |
| 185 example, to change the colors for the C syntax: > | |
| 186 highlight cComment ctermfg=Green guifg=Green | |
| 187 | |
| 188 4. Write that file in the "after/syntax" directory. Use the name of the | |
| 189 syntax, with ".vim" added. For our C syntax: > | |
| 190 :w ~/.vim/after/syntax/c.vim | |
| 191 | |
| 192 That's it. The next time you edit a C file the Comment color will be | |
| 193 different. You don't even have to restart Vim. | |
| 194 | |
| 169 | 195 If you have multiple files, you can use the filetype as the directory name. |
| 196 All the "*.vim" files in this directory will be used, for example: | |
| 197 ~/.vim/after/syntax/c/one.vim | |
| 198 ~/.vim/after/syntax/c/two.vim | |
| 199 | |
| 7 | 200 |
| 201 REPLACING AN EXISTING SYNTAX FILE *mysyntaxfile-replace* | |
| 202 | |
| 203 If you don't like a distributed syntax file, or you have downloaded a new | |
| 204 version, follow the same steps as for |mysyntaxfile| above. Just make sure | |
| 205 that you write the syntax file in a directory that is early in 'runtimepath'. | |
| 3445 | 206 Vim will only load the first syntax file found, assuming that it sets |
| 207 b:current_syntax. | |

| 7 | 216 The name for a highlight or syntax group must consist of ASCII letters, digits |
| 6647 | 217 and the underscore. As a regexp: "[a-zA-Z0-9_]*". However, Vim does not give |
| 28517 | 218 an error when using other characters. The maximum length of a group name is |
| 27537 | 219 about 200 bytes. *E1249* |
| 7 | 220 |
| 19574 | 221 To be able to allow each user to pick their favorite set of colors, there must |
| 7 | 222 be preferred names for highlight groups that are common for many languages. |
| 223 These are the suggested group names (if syntax highlighting works properly | |
| 224 you can see the actual color, except for "Ignore"): | |
| 225 | |
| 226 *Comment any comment | |
| 227 | |
| 228 *Constant any constant | |
| 229 String a string constant: "this is a string" | |
| 230 Character a character constant: 'c', '\n' | |
| 231 Number a number constant: 234, 0xff | |
| 232 Boolean a boolean constant: TRUE, false | |
| 233 Float a floating point constant: 2.3e10 | |
| 234 | |
| 235 *Identifier any variable name | |
| 236 Function function name (also: methods for classes) | |
| 237 | |
| 238 *Statement any statement | |
| 239 Conditional if, then, else, endif, switch, etc. | |
| 240 Repeat for, do, while, etc. | |
| 241 Label case, default, etc. | |
| 242 Operator "sizeof", "+", "*", etc. | |
| 243 Keyword any other keyword | |
| 244 Exception try, catch, throw | |
| 245 | |
| 246 *PreProc generic Preprocessor | |
| 247 Include preprocessor #include | |
| 248 Define preprocessor #define | |
| 249 Macro same as Define | |
| 250 PreCondit preprocessor #if, #else, #endif, etc. | |
| 251 | |
| 252 *Type int, long, char, etc. | |
| 253 StorageClass static, register, volatile, etc. | |
| 254 Structure struct, union, enum, etc. | |
| 255 Typedef A typedef | |
| 256 | |
| 257 *Special any special symbol | |
| 258 SpecialChar special character in a constant | |
| 259 Tag you can use CTRL-] on this | |
| 260 Delimiter character that needs attention | |
| 261 SpecialComment special things inside a comment | |
| 262 Debug debugging statements | |
| 263 | |
| 264 *Underlined text that stands out, HTML links | |

266 *Ignore left blank, hidden |hl-Ignore| |

| 268 *Error any erroneous construct | |
| 269 | |
| 270 *Todo anything that needs extra attention; mostly the | |
| 271 keywords TODO FIXME and XXX | |
| 272 | |
| 273 The names marked with * are the preferred groups; the others are minor groups. | |
| 274 For the preferred groups, the "syntax.vim" file contains default highlighting. | |
| 275 The minor groups are linked to the preferred groups, so they get the same | |
| 276 highlighting. You can override these defaults by using ":highlight" commands | |
| 277 after sourcing the "syntax.vim" file. | |
| 278 | |
| 279 Note that highlight group names are not case sensitive. "String" and "string" | |
| 280 can be used for the same group. | |

| 290 3. Syntax loading procedure *syntax-loading* | |
| 291 | |
| 292 This explains the details that happen when the command ":syntax enable" is | |
| 293 issued. When Vim initializes itself, it finds out where the runtime files are | |
| 294 located. This is used here as the variable |$VIMRUNTIME|. | |
| 295 | |
| 296 ":syntax enable" and ":syntax on" do the following: | |
| 297 | |
| 298 Source $VIMRUNTIME/syntax/syntax.vim | |
| 299 | | |
| 300 +- Clear out any old syntax by sourcing $VIMRUNTIME/syntax/nosyntax.vim | |
| 301 | | |
| 302 +- Source first syntax/synload.vim in 'runtimepath' | |
| 303 | | | |
| 304 | +- Setup the colors for syntax highlighting. If a color scheme is | |
| 305 | | defined it is loaded again with ":colors {name}". Otherwise | |
| 306 | | ":runtime! syntax/syncolor.vim" is used. ":syntax on" overrules | |
| 307 | | existing colors, ":syntax enable" only sets groups that weren't | |
| 308 | | set yet. | |
| 309 | | | |
| 310 | +- Set up syntax autocmds to load the appropriate syntax file when | |
| 311 | | the 'syntax' option is set. *synload-1* | |
| 312 | | | |
| 313 | +- Source the user's optional file, from the |mysyntaxfile| variable. | |
| 314 | This is for backwards compatibility with Vim 5.x only. *synload-2* | |
| 315 | | |
| 316 +- Do ":filetype on", which does ":runtime! filetype.vim". It loads any | |
| 317 | filetype.vim files found. It should always Source | |
| 318 | $VIMRUNTIME/filetype.vim, which does the following. | |
| 319 | | | |
| 320 | +- Install autocmds based on suffix to set the 'filetype' option | |
| 321 | | This is where the connection between file name and file type is | |
| 322 | | made for known file types. *synload-3* | |
| 323 | | | |
| 324 | +- Source the user's optional file, from the *myfiletypefile* | |
| 325 | | variable. This is for backwards compatibility with Vim 5.x only. | |
| 326 | | *synload-4* | |
| 327 | | | |
| 328 | +- Install one autocommand which sources scripts.vim when no file | |
| 329 | | type was detected yet. *synload-5* | |
| 330 | | | |
| 331 | +- Source $VIMRUNTIME/menu.vim, to setup the Syntax menu. |menu.vim| | |
| 332 | | |
| 333 +- Install a FileType autocommand to set the 'syntax' option when a file | |
| 334 | type has been detected. *synload-6* | |
| 335 | | |
| 336 +- Execute syntax autocommands to start syntax highlighting for each | |
| 337 already loaded buffer. | |
| 338 | |
| 339 | |
| 340 Upon loading a file, Vim finds the relevant syntax file as follows: | |
| 341 | |
| 342 Loading the file triggers the BufReadPost autocommands. | |
| 343 | | |
| 344 +- If there is a match with one of the autocommands from |synload-3| | |
| 345 | (known file types) or |synload-4| (user's file types), the 'filetype' | |
| 346 | option is set to the file type. | |
| 347 | | |
| 348 +- The autocommand at |synload-5| is triggered. If the file type was not | |
| 349 | found yet, then scripts.vim is searched for in 'runtimepath'. This | |
| 350 | should always load $VIMRUNTIME/scripts.vim, which does the following. | |
| 351 | | | |
| 352 | +- Source the user's optional file, from the *myscriptsfile* | |
| 353 | | variable. This is for backwards compatibility with Vim 5.x only. | |
| 354 | | | |
| 355 | +- If the file type is still unknown, check the contents of the file, | |
| 356 | again with checks like "getline(1) =~ pattern" as to whether the | |
| 357 | file type can be recognized, and set 'filetype'. | |
| 358 | | |
| 359 +- When the file type was determined and 'filetype' was set, this | |
| 360 | triggers the FileType autocommand |synload-6| above. It sets | |
| 361 | 'syntax' to the determined file type. | |
| 362 | | |
| 363 +- When the 'syntax' option was set above, this triggers an autocommand | |
| 364 | from |synload-1| (and |synload-2|). This find the main syntax file in | |
| 365 | 'runtimepath', with this command: | |
| 366 | runtime! syntax/<name>.vim | |
| 367 | | |
| 368 +- Any other user installed FileType or Syntax autocommands are | |
| 369 triggered. This can be used to change the highlighting for a specific | |
| 370 syntax. | |
| 371 | |

396 - Some truly ancient browsers may not show the background colors. |
| 7 | 397 - From most browsers you can also print the file (in color)! |
| 3713 | 398 - The latest TOhtml may actually work with older versions of Vim, but some |
| 2642 | 399 features such as conceal support will not function, and the colors may be |
| 400 incorrect for an old Vim without GUI support compiled in. | |
| 7 | 401 |

| 405 < | |
| 3713 | 406 *g:html_start_line* *g:html_end_line* |
| 407 To restrict the conversion to a range of lines, use a range with the |:TOhtml| | |
| 408 command below, or set "g:html_start_line" and "g:html_end_line" to the first | |
| 409 and last line to be converted. Example, using the last set Visual area: > | |

| 447 *g:html_whole_filler* | |
| 448 Default: 0. | |
| 449 When 0, if |g:html_diff_one_file| is 1, a sequence of more than 3 filler lines | |
| 450 is displayed as three lines with the middle line mentioning the total number | |
| 451 of inserted lines. | |
| 452 When 1, always display all inserted lines as if |g:html_diff_one_file| were | |
| 453 not set. | |

| 456 < | |
| 457 *TOhtml-performance* *g:html_no_progress* | |
| 458 Default: 0. | |
| 459 When 0, display a progress bar in the statusline for each major step in the | |
| 460 2html.vim conversion process. | |
| 461 When 1, do not display the progress bar. This offers a minor speed improvement | |
| 462 but you won't have any idea how much longer the conversion might take; for big | |
| 463 files it can take a long time! | |
| 464 Example: > | |
| 465 | |
| 466 let g:html_no_progress = 1 | |
| 467 < | |
| 468 You can obtain better performance improvements by also instructing Vim to not | |
| 469 run interactively, so that too much time is not taken to redraw as the script | |
| 470 moves through the buffer, switches windows, and the like: > | |
| 471 | |
| 472 vim -E -s -c "let g:html_no_progress=1" -c "syntax on" -c "set ft=c" -c "runtime syntax/2html.vim" -cwqa myfile.c | |
| 473 < | |
| 474 Note that the -s flag prevents loading your .vimrc and any plugins, so you | |
| 475 need to explicitly source/enable anything that will affect the HTML | |
| 476 conversion. See |-E| and |-s-ex| for details. It is probably best to create a | |
| 477 script to replace all the -c commands and use it with the -u flag instead of | |
| 478 specifying each command separately. | |
| 479 | |
| 18639 | 480 *hl-TOhtmlProgress* *TOhtml-progress-color* |
| 481 When displayed, the progress bar will show colored boxes along the statusline | |
| 482 as the HTML conversion proceeds. By default, the background color as the | |
| 483 current "DiffDelete" highlight group is used. If "DiffDelete" and "StatusLine" | |
| 484 have the same background color, TOhtml will automatically adjust the color to | |
| 485 differ. If you do not like the automatically selected colors, you can define | |
| 486 your own highlight colors for the progress bar. Example: > | |
| 487 | |
| 488 hi TOhtmlProgress guifg=#c0ffee ctermbg=7 | |
| 489 < | |

| 3713 | 519 *g:html_use_css* |
| 520 Default: 1. | |
| 18639 | 521 When 1, generate valid HTML 5 markup with CSS styling, supported in all modern |
| 522 browsers and many old browsers. | |
| 3713 | 523 When 0, generate <font> tags and similar outdated markup. This is not |
| 524 recommended but it may work better in really old browsers, email clients, | |
| 525 forum posts, and similar situations where basic CSS support is unavailable. | |
| 526 Example: > | |
| 527 :let g:html_use_css = 0 | |
| 528 < | |
| 529 *g:html_ignore_conceal* | |
| 530 Default: 0. | |
| 531 When 0, concealed text is removed from the HTML and replaced with a character | |
| 532 from |:syn-cchar| or 'listchars' as appropriate, depending on the current | |
| 533 value of 'conceallevel'. | |
| 534 When 1, include all text from the buffer in the generated HTML, even if it is | |
| 535 |conceal|ed. | |
| 536 | |
| 537 Either of the following commands will ensure that all text in the buffer is | |
| 538 included in the generated HTML (unless it is folded): > | |
| 539 :let g:html_ignore_conceal = 1 | |
| 540 :setl conceallevel=0 | |
| 541 < | |
| 542 *g:html_ignore_folding* | |
| 543 Default: 0. | |
| 544 When 0, text in a closed fold is replaced by the text shown for the fold in | |
| 545 Vim (|fold-foldtext|). See |g:html_dynamic_folds| if you also want to allow | |
| 546 the user to expand the fold as in Vim to see the text inside. | |
| 547 When 1, include all text from the buffer in the generated HTML; whether the | |
| 548 text is in a fold has no impact at all. |g:html_dynamic_folds| has no effect. | |
| 549 | |
| 550 Either of these commands will ensure that all text in the buffer is included | |
| 551 in the generated HTML (unless it is concealed): > | |
| 552 zR | |
| 553 :let g:html_ignore_folding = 1 | |
| 554 < | |
| 555 *g:html_dynamic_folds* | |
| 556 Default: 0. | |
| 557 When 0, text in a closed fold is not included at all in the generated HTML. | |
| 558 When 1, generate javascript to open a fold and show the text within, just like | |
| 559 in Vim. | |
| 560 | |
| 561 Setting this variable to 1 causes 2html.vim to always use CSS for styling, | |
| 562 regardless of what |g:html_use_css| is set to. | |
| 563 | |
| 564 This variable is ignored when |g:html_ignore_folding| is set. | |
| 565 > | |
| 566 :let g:html_dynamic_folds = 1 | |
| 567 < | |
| 568 *g:html_no_foldcolumn* | |
| 569 Default: 0. | |
| 570 When 0, if |g:html_dynamic_folds| is 1, generate a column of text similar to | |
| 571 Vim's foldcolumn (|fold-foldcolumn|) the user can click on to toggle folds | |
| 572 open or closed. The minimum width of the generated text column is the current | |
| 573 'foldcolumn' setting. | |
| 574 When 1, do not generate this column; instead, hovering the mouse cursor over | |
| 575 folded text will open the fold as if |g:html_hover_unfold| were set. | |
| 576 > | |

580 Default: Empty string. |
| 3713 | 581 This option prevents certain regions of the generated HTML from being copied, |
| 582 when you select all text in document rendered in a browser and copy it. Useful | |
| 583 for allowing users to copy-paste only the source text even if a fold column or | |
| 584 line numbers are shown in the generated content. Specify regions to be | |
| 585 affected in this way as follows: | |
| 586 f: fold column | |
| 587 n: line numbers (also within fold text) | |
| 588 t: fold text | |
| 589 d: diff filler | |
| 590 | |
| 591 Example, to make the fold column and line numbers uncopyable: > | |
| 592 :let g:html_prevent_copy = "fn" | |
| 593 < | |
| 18639 | 594 The method used to prevent copying in the generated page depends on the value |
| 595 of |g:html_use_input_for_pc|. | |
| 596 | |
| 597 *g:html_use_input_for_pc* | |
| 598 Default: "fallback" | |
| 599 If |g:html_prevent_copy| is non-empty, then: | |
| 600 | |
| 601 When "all", read-only <input> elements are used in place of normal text for | |
| 602 uncopyable regions. In some browsers, especially older browsers, after | |
| 603 selecting an entire page and copying the selection, the <input> tags are not | |
| 604 pasted with the page text. If |g:html_no_invalid| is 0, the <input> tags have | |
| 605 invalid type; this works in more browsers, but the page will not validate. | |

606 Note: This method does NOT work in recent versions of Chrome and equivalent |
| 18639 | 607 browsers; the <input> tags get pasted with the text. |
| 608 | |
| 609 When "fallback" (default value), the same <input> elements are generated for | |
| 610 older browsers, but newer browsers (detected by CSS feature query) hide the | |
| 611 <input> elements and instead use generated content in an ::before pseudoelement | |
| 612 to display the uncopyable text. This method should work with the largest | |
| 613 number of browsers, both old and new. | |
| 614 | |
| 615 When "none", the <input> elements are not generated at all. Only the | |
| 616 generated-content method is used. This means that old browsers, notably | |
| 617 Internet Explorer, will either copy the text intended not to be copyable, or | |
| 618 the non-copyable text may not appear at all. However, this is the most | |
| 619 standards-based method, and there will be much less markup. | |
| 3713 | 620 |
| 621 *g:html_no_invalid* | |
| 622 Default: 0. | |
| 18639 | 623 When 0, if |g:html_prevent_copy| is non-empty and |g:html_use_input_for_pc| is |
| 624 not "none", an invalid attribute is intentionally inserted into the <input> | |
| 625 element for the uncopyable areas. This prevents pasting the <input> elements | |
| 626 in some applications. Specifically, some versions of Microsoft Word will not | |
| 627 paste the <input> elements if they contain this invalid attribute. When 1, no | |
| 628 invalid markup is inserted, and the generated page should validate. However, | |
| 629 <input> elements may be pasted into some applications and can be difficult to | |
| 630 remove afterward. | |
| 3713 | 631 |
| 632 *g:html_hover_unfold* | |
| 633 Default: 0. | |
| 634 When 0, the only way to open a fold generated by 2html.vim with | |
| 635 |g:html_dynamic_folds| set, is to click on the generated fold column. | |
| 636 When 1, use CSS 2.0 to allow the user to open a fold by moving the mouse | |
| 637 cursor over the displayed fold text. This is useful to allow users with | |
| 638 disabled javascript to view the folded text. | |
| 639 | |
| 640 Note that old browsers (notably Internet Explorer 6) will not support this | |
| 641 feature. Browser-specific markup for IE6 is included to fall back to the | |
| 642 normal CSS1 styling so that the folds show up correctly for this browser, but | |
| 643 they will not be openable without a foldcolumn. | |

667 Default: Current 'wrap' setting. |
| 3713 | 668 When 0, if |g:html_no_pre| is 0 or unset, the text in the generated HTML does |
| 669 not wrap at the edge of the browser window. | |
| 670 When 1, if |g:html_use_css| is 1, the CSS 2.0 "white-space:pre-wrap" value is | |
| 671 used, causing the text to wrap at whitespace at the edge of the browser | |
| 672 window. | |
| 673 Explicitly enable text wrapping: > | |
| 674 :let g:html_pre_wrap = 1 | |
| 675 Explicitly disable wrapping: > | |
| 676 :let g:html_pre_wrap = 0 | |
| 677 Go back to default, determine wrapping from 'wrap' setting: > | |
| 678 :unlet g:html_pre_wrap | |
| 679 < | |
| 680 *g:html_no_pre* | |
| 681 Default: 0. | |
| 682 When 0, buffer text in the generated HTML is surrounded by <pre>...</pre> | |
| 683 tags. Series of whitespace is shown as in Vim without special markup, and tab | |
| 684 characters can be included literally (see |g:html_expand_tabs|). | |
| 685 When 1 (not recommended), the <pre> tags are omitted, and a plain <div> is | |
| 686 used instead. Whitespace is replaced by a series of character | |
| 687 references, and <br> is used to end each line. This is another way to allow | |
| 688 text in the generated HTML is wrap (see |g:html_pre_wrap|) which also works in | |
| 689 old browsers, but may cause noticeable differences between Vim's display and | |
| 690 the rendered page generated by 2html.vim. | |
| 691 > | |
| 692 :let g:html_no_pre = 1 | |
| 693 < | |
| 694 *g:html_expand_tabs* | |
| 15033 | 695 Default: 0 if 'tabstop' is 8, 'expandtab' is 0, 'vartabstop' is not in use, |
| 696 and no fold column or line numbers occur in the generated HTML; | |
| 697 1 otherwise. | |
| 698 When 1, <Tab> characters in the buffer text are replaced with an appropriate | |
| 3713 | 699 number of space characters, or references if |g:html_no_pre| is 1. |
| 15033 | 700 When 0, if |g:html_no_pre| is 0 or unset, <Tab> characters in the buffer text |
| 3713 | 701 are included as-is in the generated HTML. This is useful for when you want to |
| 702 allow copy and paste from a browser without losing the actual whitespace in | |
| 703 the source document. Note that this can easily break text alignment and | |
| 704 indentation in the HTML, unless set by default. | |
| 705 | |
| 706 Force |2html.vim| to keep <Tab> characters: > | |
| 707 :let g:html_expand_tabs = 0 | |
| 708 < | |

| 710 :let g:html_expand_tabs = 1 | |

| 712 *TOhtml-encoding-detect* *TOhtml-encoding* | |
| 713 It is highly recommended to set your desired encoding with | |
| 714 |g:html_use_encoding| for any content which will be placed on a web server. | |
| 715 | |
| 716 If you do not specify an encoding, |2html.vim| uses the preferred IANA name | |
| 717 for the current value of 'fileencoding' if set, or 'encoding' if not. | |
| 718 'encoding' is always used for certain 'buftype' values. 'fileencoding' will be | |
| 719 set to match the chosen document encoding. | |
| 720 | |
| 721 Automatic detection works for the encodings mentioned specifically by name in | |
| 722 |encoding-names|, but TOhtml will only automatically use those encodings with | |
| 723 wide browser support. However, you can override this to support specific | |
| 724 encodings that may not be automatically detected by default (see options | |
| 725 below). See http://www.iana.org/assignments/character-sets for the IANA names. | |

727 Note: By default all Unicode encodings are converted to UTF-8 with no BOM in |
| 3713 | 728 the generated HTML, as recommended by W3C: |
| 729 | |
| 730 http://www.w3.org/International/questions/qa-choosing-encodings | |
| 731 http://www.w3.org/International/questions/qa-byte-order-mark | |
| 732 | |
| 733 *g:html_use_encoding* | |
| 734 Default: none, uses IANA name for current 'fileencoding' as above. | |
| 735 To overrule all automatic charset detection, set g:html_use_encoding to the | |
| 736 name of the charset to be used. It is recommended to set this variable to | |
| 737 something widely supported, like UTF-8, for anything you will be hosting on a | |
| 738 webserver: > | |
| 739 :let g:html_use_encoding = "UTF-8" | |
| 740 You can also use this option to omit the line that specifies the charset | |
| 741 entirely, by setting g:html_use_encoding to an empty string (NOT recommended): > | |
| 742 :let g:html_use_encoding = "" | |
| 743 To go back to the automatic mechanism, delete the |g:html_use_encoding| | |
| 744 variable: > | |
| 745 :unlet g:html_use_encoding | |
| 746 < | |
| 747 *g:html_encoding_override* | |
| 748 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
| 749 mentioned by name at |encoding-names|. | |
| 750 This option allows |2html.vim| to detect the correct 'fileencoding' when you | |
| 751 specify an encoding with |g:html_use_encoding| which is not in the default | |
| 752 list of conversions. | |
| 753 | |
| 754 This is a dictionary of charset-encoding pairs that will replace existing | |
| 755 pairs automatically detected by TOhtml, or supplement with new pairs. | |
| 756 | |
| 757 Detect the HTML charset "windows-1252" as the encoding "8bit-cp1252": > | |
| 758 :let g:html_encoding_override = {'windows-1252': '8bit-cp1252'} | |
| 759 < | |
| 760 *g:html_charset_override* | |
| 761 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
| 762 mentioned by name at |encoding-names| and which have wide | |
| 763 browser support. | |
| 764 This option allows |2html.vim| to detect the HTML charset for any | |
| 765 'fileencoding' or 'encoding' which is not detected automatically. You can also | |
| 766 use it to override specific existing encoding-charset pairs. For example, | |
| 767 TOhtml will by default use UTF-8 for all Unicode/UCS encodings. To use UTF-16 | |
| 768 and UTF-32 instead, use: > | |
| 769 :let g:html_charset_override = {'ucs-4': 'UTF-32', 'utf-16': 'UTF-16'} | |
| 770 | |
| 771 Note that documents encoded in either UTF-32 or UTF-16 have known | |
| 772 compatibility problems with some major browsers. | |

880 one of the first five lines in the file. No non-white text must be |
| 3682 | 881 immediately before or after this text. Note that specifying asmsyntax=foo is |
| 882 equivalent to setting ft=foo in a |modeline|, and that in case of a conflict | |
| 883 between the two settings the one from the modeline will take precedence (in | |
| 884 particular, if you have ft=asm in the modeline, you will get the GNU syntax | |
| 885 highlighting regardless of what is specified as asmsyntax). | |
| 7 | 886 |
| 887 The syntax type can always be overruled for a specific buffer by setting the | |
| 888 b:asmsyntax variable: > | |
| 1624 | 889 :let b:asmsyntax = "nasm" |
| 7 | 890 |
| 891 If b:asmsyntax is not set, either automatically or by hand, then the value of | |
| 892 the global variable asmsyntax is used. This can be seen as a default assembly | |
| 893 language: > | |
| 1624 | 894 :let asmsyntax = "nasm" |
| 7 | 895 |
| 896 As a last resort, if nothing is defined, the "asm" syntax is used. | |

| 915 *.asp and *.asa files could be either Perl or Visual Basic script. Since it's | |
| 916 hard to detect this you can set two global variables to tell Vim what you are | |
| 917 using. For Perl script use: > | |
| 918 :let g:filetype_asa = "aspperl" | |
| 919 :let g:filetype_asp = "aspperl" | |
| 920 For Visual Basic use: > | |

| 856 | 925 BAAN *baan.vim* *baan-syntax* |
| 844 | 926 |
| 25402 | 927 The baan.vim gives syntax support for BaanC of release BaanIV up to SSA ERP LN |
| 844 | 928 for both 3 GL and 4 GL programming. Large number of standard defines/constants |
| 929 are supported. | |
| 930 | |
| 931 Some special violation of coding standards will be signalled when one specify | |
| 932 in ones |.vimrc|: > | |
| 933 let baan_code_stds=1 | |
| 934 | |
| 935 *baan-folding* | |
| 936 | |
| 937 Syntax folding can be enabled at various levels through the variables | |
| 938 mentioned below (Set those in your |.vimrc|). The more complex folding on | |
| 939 source blocks and SQL can be CPU intensive. | |
| 940 | |
| 941 To allow any folding and enable folding at function level use: > | |
| 942 let baan_fold=1 | |
| 943 Folding can be enabled at source block level as if, while, for ,... The | |
| 944 indentation preceding the begin/end keywords has to match (spaces are not | |
| 945 considered equal to a tab). > | |
| 946 let baan_fold_block=1 | |
| 947 Folding can be enabled for embedded SQL blocks as SELECT, SELECTDO, | |
| 856 | 948 SELECTEMPTY, ... The indentation preceding the begin/end keywords has to |
| 844 | 949 match (spaces are not considered equal to a tab). > |
| 950 let baan_fold_sql=1 | |
| 856 | 951 Note: Block folding can result in many small folds. It is suggested to |:set| |
| 844 | 952 the options 'foldminlines' and 'foldnestmax' in |.vimrc| or use |:setlocal| in |
| 953 .../after/syntax/baan.vim (see |after-directory|). Eg: > | |
| 954 set foldminlines=5 | |
| 955 set foldnestmax=6 | |

| 957 | |
| 501 | 958 BASIC *basic.vim* *vb.vim* *ft-basic-syntax* *ft-vb-syntax* |
| 7 | 959 |
| 27321 | 960 Both Visual Basic and "normal" BASIC use the extension ".bas". To detect |
| 7 | 961 which one should be used, Vim checks for the string "VB_Name" in the first |
| 962 five lines of the file. If it is not found, filetype will be "basic", | |
| 963 otherwise "vb". Files with the ".frm" extension will always be seen as Visual | |
| 964 Basic. | |
| 965 | |
| 27321 | 966 If the automatic detection doesn't work for you or you only edit, for |
| 967 example, FreeBASIC files, use this in your startup vimrc: > | |
| 968 :let filetype_bas = "freebasic" | |
| 969 | |
| 7 | 970 |
| 501 | 971 C *c.vim* *ft-c-syntax* |
| 7 | 972 |
| 973 A few things in C highlighting are optional. To enable them assign any value | |
| 18750 | 974 (including zero) to the respective variable. Example: > |
| 1624 | 975 :let c_comment_strings = 1 |
| 18750 | 976 :let c_no_bracket_error = 0 |
| 977 To disable them use `:unlet`. Example: > | |
| 7 | 978 :unlet c_comment_strings |
| 18750 | 979 Setting the value to zero doesn't work! |
| 7 | 980 |
| 14999 | 981 An alternative is to switch to the C++ highlighting: > |
| 982 :set filetype=cpp | |
| 983 | |

1007 *c_no_bsd* don't highlight BSD specific types |
| 7 | 1008 |
| 36 | 1009 When 'foldmethod' is set to "syntax" then /* */ comments and { } blocks will |
| 1010 become a fold. If you don't want comments to become a fold use: > | |
| 1011 :let c_no_comment_fold = 1 | |
| 842 | 1012 "#if 0" blocks are also folded, unless: > |
| 1013 :let c_no_if0_fold = 1 | |
| 36 | 1014 |
| 7 | 1015 If you notice highlighting errors while scrolling backwards, which are fixed |
| 1016 when redrawing with CTRL-L, try setting the "c_minlines" internal variable | |
| 1017 to a larger number: > | |
| 1018 :let c_minlines = 100 | |
| 1019 This will make the syntax synchronization start 100 lines before the first | |
| 1020 displayed line. The default value is 50 (15 when c_no_if0 is set). The | |
| 1021 disadvantage of using a larger number is that redrawing can become slow. | |
| 1022 | |
| 1023 When using the "#if 0" / "#endif" comment highlighting, notice that this only | |
| 1024 works when the "#if 0" is within "c_minlines" from the top of the window. If | |
| 1025 you have a long "#if 0" construct it will not be highlighted correctly. | |
| 1026 | |
| 1027 To match extra items in comments, use the cCommentGroup cluster. | |
| 1028 Example: > | |
| 1029 :au Syntax c call MyCadd() | |
| 1030 :function MyCadd() | |
| 1031 : syn keyword cMyItem contained Ni | |
| 1032 : syn cluster cCommentGroup add=cMyItem | |
| 1033 : hi link cMyItem Title | |
| 1034 :endfun | |
| 1035 | |
| 1036 ANSI constants will be highlighted with the "cConstant" group. This includes | |
| 1037 "NULL", "SIG_IGN" and others. But not "TRUE", for example, because this is | |
| 1038 not in the ANSI standard. If you find this confusing, remove the cConstant | |
| 1039 highlighting: > | |
| 1040 :hi link cConstant NONE | |
| 1041 | |
| 1042 If you see '{' and '}' highlighted as an error where they are OK, reset the | |
| 1043 highlighting for cErrInParen and cErrInBracket. | |
| 1044 | |
| 1045 If you want to use folding in your C files, you can add these lines in a file | |

| 1054 the C syntax file. See |c.vim| for all the settings that are available for C. | |
| 1055 | |
| 1056 By setting a variable you can tell Vim to use Ch syntax for *.h files, instead | |
| 1057 of C or C++: > | |
| 1058 :let ch_syntax_for_h = 1 | |
| 1059 | |

| 1063 Chill syntax highlighting is similar to C. See |c.vim| for all the settings | |
| 1064 that are available. Additionally there is: | |
| 1065 | |
| 1066 chill_space_errors like c_space_errors | |
| 1067 chill_comment_string like c_comment_strings | |
| 1068 chill_minlines like c_minlines | |

| 501 | 1071 CHANGELOG *changelog.vim* *ft-changelog-syntax* |
| 7 | 1072 |
| 1073 ChangeLog supports highlighting spaces at the start of a line. | |
| 1074 If you do not like this, add following line to your .vimrc: > | |
| 1075 let g:changelog_spacing_errors = 0 | |
| 1076 This works the next time you edit a changelog file. You can also use | |
| 1077 "b:changelog_spacing_errors" to set this per buffer (before loading the syntax | |
| 1078 file). | |
| 1079 | |
| 1080 You can change the highlighting used, e.g., to flag the spaces as an error: > | |
| 1081 :hi link ChangelogError Error | |
| 1082 Or to avoid the highlighting: > | |
| 1083 :hi link ChangelogError NONE | |

| 26100 | 1103 There is also *b:clojure_syntax_keywords* which is a buffer-local variant of |
| 1104 this variable intended for use by plugin authors to highlight symbols | |
| 1105 dynamically. | |
| 1106 | |
| 1107 By setting the *b:clojure_syntax_without_core_keywords* variable, vars from | |
| 1108 "clojure.core" will not be highlighted by default. This is useful for | |

| 1135 versus development) and other factors. To enable legacy code highlighting, | |
| 1136 add this line to your .vimrc: > | |
| 1137 :let cobol_legacy_code = 1 | |
| 1138 To disable it again, use this: > | |

| 501 | 1163 CSH *csh.vim* *ft-csh-syntax* |
| 7 | 1164 |
| 1165 This covers the shell named "csh". Note that on some systems tcsh is actually | |
| 1166 used. | |
| 1167 | |
| 1168 Detecting whether a file is csh or tcsh is notoriously hard. Some systems | |
| 1169 symlink /bin/csh to /bin/tcsh, making it almost impossible to distinguish | |
| 1170 between csh and tcsh. In case VIM guesses wrong you can set the | |
| 2965 | 1171 "filetype_csh" variable. For using csh: *g:filetype_csh* |
| 1172 > | |
| 1173 :let g:filetype_csh = "csh" | |
| 7 | 1174 |
| 1175 For using tcsh: > | |
| 1176 | |
| 2965 | 1177 :let g:filetype_csh = "tcsh" |
| 7 | 1178 |
| 1179 Any script with a tcsh extension or a standard tcsh filename (.tcshrc, | |
| 1180 tcsh.tcshrc, tcsh.login) will have filetype tcsh. All other tcsh/csh scripts | |
| 237 | 1181 will be classified as tcsh, UNLESS the "filetype_csh" variable exists. If the |
| 7 | 1182 "filetype_csh" variable exists, the filetype will be set to the value of the |
| 1183 variable. | |
| 1184 | |
| 1185 | |
| 501 | 1186 CYNLIB *cynlib.vim* *ft-cynlib-syntax* |
| 7 | 1187 |
| 1188 Cynlib files are C++ files that use the Cynlib class library to enable | |
| 237 | 1189 hardware modelling and simulation using C++. Typically Cynlib files have a .cc |
| 7 | 1190 or a .cpp extension, which makes it very difficult to distinguish them from a |
| 237 | 1191 normal C++ file. Thus, to enable Cynlib highlighting for .cc files, add this |
| 7 | 1192 line to your .vimrc file: > |
| 1193 | |
| 1194 :let cynlib_cyntax_for_cc=1 | |
| 1195 | |
| 1196 Similarly for cpp files (this extension is only usually used in Windows) > | |
| 1197 | |
| 1198 :let cynlib_cyntax_for_cpp=1 | |
| 1199 | |
| 1200 To disable these again, use this: > | |

| 501 | 1206 CWEB *cweb.vim* *ft-cweb-syntax* |

| 1209 doesn't work for you, or you don't edit Progress at all, use this in your | |
| 1210 startup vimrc: > | |

| 18456 | 1214 DART *dart.vim* *ft-dart-syntax* |
| 1215 | |
| 1216 Dart is an object-oriented, typed, class defined, garbage collected language | |
| 1217 used for developing mobile, desktop, web, and back-end applications. Dart uses | |
| 1218 a C-like syntax derived from C, Java, and JavaScript, with features adopted | |
| 1219 from Smalltalk, Python, Ruby, and others. | |
| 1220 | |
| 1221 More information about the language and its development environment at the | |
| 1222 official Dart language website at https://dart.dev | |
| 1223 | |
| 1224 dart.vim syntax detects and highlights Dart statements, reserved words, | |
| 1225 type declarations, storage classes, conditionals, loops, interpolated values, | |
| 1226 and comments. There is no support idioms from Flutter or any other Dart | |
| 1227 framework. | |

| 501 | 1257 DIRCOLORS *dircolors.vim* *ft-dircolors-syntax* |
| 7 | 1258 |
| 1259 The dircolors utility highlighting definition has one option. It exists to | |
| 1260 provide compatibility with the Slackware GNU/Linux distributions version of | |
| 1261 the command. It adds a few keywords that are generally ignored by most | |
| 1262 versions. On Slackware systems, however, the utility accepts the keywords and | |
| 1263 uses them for processing. To enable the Slackware keywords add the following | |
| 1264 line to your startup file: > | |
| 1265 let dircolors_is_slackware = 1 | |
| 1266 | |
| 1267 | |
| 501 | 1268 DOCBOOK *docbk.vim* *ft-docbk-syntax* *docbook* |
| 2662 | 1269 DOCBOOK XML *docbkxml.vim* *ft-docbkxml-syntax* |
| 1270 DOCBOOK SGML *docbksgml.vim* *ft-docbksgml-syntax* | |
| 7 | 1271 |
| 1272 There are two types of DocBook files: SGML and XML. To specify what type you | |
| 1273 are using the "b:docbk_type" variable should be set. Vim does this for you | |
| 1274 automatically if it can recognize the type. When Vim can't guess it the type | |
| 1275 defaults to XML. | |
| 1276 You can set the type manually: > | |
| 1277 :let docbk_type = "sgml" | |
| 1278 or: > | |
| 1279 :let docbk_type = "xml" | |
| 1280 You need to do this before loading the syntax file, which is complicated. | |
| 1281 Simpler is setting the filetype to "docbkxml" or "docbksgml": > | |
| 1282 :set filetype=docbksgml | |
| 1283 or: > | |
| 1284 :set filetype=docbkxml | |
| 1285 | |
| 3967 | 1286 You can specify the DocBook version: > |
| 1287 :let docbk_ver = 3 | |
| 1288 When not set 4 is used. | |
| 1289 | |
| 7 | 1290 |
| 501 | 1291 DOSBATCH *dosbatch.vim* *ft-dosbatch-syntax* |
| 7 | 1292 |
| 1293 There is one option with highlighting DOS batch files. This covers new | |
| 1294 extensions to the Command Interpreter introduced with Windows 2000 and | |
| 1295 is controlled by the variable dosbatch_cmdextversion. For Windows NT | |
| 1296 this should have the value 1, and for Windows 2000 it should be 2. | |
| 1297 Select the version you want with the following line: > | |
| 1298 | |
| 15 | 1299 :let dosbatch_cmdextversion = 1 |
| 7 | 1300 |
| 1301 If this variable is not defined it defaults to a value of 2 to support | |
| 1302 Windows 2000. | |
| 1303 | |
| 15 | 1304 A second option covers whether *.btm files should be detected as type |
| 237 | 1305 "dosbatch" (MS-DOS batch files) or type "btm" (4DOS batch files). The latter |
| 1306 is used by default. You may select the former with the following line: > | |
| 15 | 1307 |
| 1308 :let g:dosbatch_syntax_for_btm = 1 | |
| 1309 | |
| 1310 If this variable is undefined or zero, btm syntax is selected. | |
| 1311 | |
| 1312 | |
| 832 | 1313 DOXYGEN *doxygen.vim* *doxygen-syntax* |
| 1314 | |
| 1315 Doxygen generates code documentation using a special documentation format | |
| 1698 | 1316 (similar to Javadoc). This syntax script adds doxygen highlighting to c, cpp, |
| 1317 idl and php files, and should also work with java. | |
| 832 | 1318 |
| 1224 | 1319 There are a few of ways to turn on doxygen formatting. It can be done |
| 1320 explicitly or in a modeline by appending '.doxygen' to the syntax of the file. | |
| 1321 Example: > | |
| 832 | 1322 :set syntax=c.doxygen |
| 1323 or > | |
| 1324 // vim:syntax=c.doxygen | |
| 1325 | |
| 3356 | 1326 It can also be done automatically for C, C++, C#, IDL and PHP files by setting |
| 1327 the global or buffer-local variable load_doxygen_syntax. This is done by | |
| 1328 adding the following to your .vimrc. > | |
| 832 | 1329 :let g:load_doxygen_syntax=1 |

1332 and are to do with non-standard highlighting options. |
| 832 | 1333 |
| 1334 Variable Default Effect ~ | |
| 1335 g:doxygen_enhanced_color | |
| 1336 g:doxygen_enhanced_colour 0 Use non-standard highlighting for | |
| 1337 doxygen comments. | |
| 1338 | |
| 1339 doxygen_my_rendering 0 Disable rendering of HTML bold, italic | |
| 1340 and html_my_rendering underline. | |
| 1341 | |
| 1342 doxygen_javadoc_autobrief 1 Set to 0 to disable javadoc autobrief | |
| 1343 colour highlighting. | |
| 1344 | |
| 1345 doxygen_end_punctuation '[.]' Set to regexp match for the ending | |
| 856 | 1346 punctuation of brief |
| 832 | 1347 |
| 14637 | 1348 There are also some highlight groups worth mentioning as they can be useful in |
| 832 | 1349 configuration. |
| 1350 | |
| 1351 Highlight Effect ~ | |
| 1352 doxygenErrorComment The colour of an end-comment when missing | |
| 1353 punctuation in a code, verbatim or dot section | |
| 1354 doxygenLinkError The colour of an end-comment when missing the | |
| 1355 \endlink from a \link section. | |
| 1356 | |
| 7 | 1357 |
| 501 | 1358 DTD *dtd.vim* *ft-dtd-syntax* |
| 7 | 1359 |
| 237 | 1360 The DTD syntax highlighting is case sensitive by default. To disable |
| 7 | 1361 case-sensitive highlighting, add the following line to your startup file: > |
| 1362 | |
| 1363 :let dtd_ignore_case=1 | |
| 1364 | |
| 237 | 1365 The DTD syntax file will highlight unknown tags as errors. If |
| 7 | 1366 this is annoying, it can be turned off by setting: > |
| 1367 | |
| 1368 :let dtd_no_tag_errors=1 | |
| 1369 | |
| 1370 before sourcing the dtd.vim syntax file. | |
| 1371 Parameter entity names are highlighted in the definition using the | |
| 1372 'Type' highlighting group and 'Comment' for punctuation and '%'. | |
| 1373 Parameter entity instances are highlighted using the 'Constant' | |
| 1374 highlighting group and the 'Type' highlighting group for the | |
| 237 | 1375 delimiters % and ;. This can be turned off by setting: > |
| 7 | 1376 |
| 1377 :let dtd_no_param_entities=1 | |
| 1378 | |
| 1379 The DTD syntax file is also included by xml.vim to highlight included dtd's. | |
| 1380 | |
| 1381 | |
| 501 | 1382 EIFFEL *eiffel.vim* *ft-eiffel-syntax* |
| 7 | 1383 |
| 1384 While Eiffel is not case-sensitive, its style guidelines are, and the | |
| 237 | 1385 syntax highlighting file encourages their use. This also allows to |
| 1386 highlight class names differently. If you want to disable case-sensitive | |
| 7 | 1387 highlighting, add the following line to your startup file: > |
| 1388 | |
| 1389 :let eiffel_ignore_case=1 | |
| 1390 | |
| 1391 Case still matters for class names and TODO marks in comments. | |
| 1392 | |
| 1393 Conversely, for even stricter checks, add one of the following lines: > | |
| 1394 | |
| 1395 :let eiffel_strict=1 | |
| 1396 :let eiffel_pedantic=1 | |
| 1397 | |
| 1398 Setting eiffel_strict will only catch improper capitalization for the | |
| 1399 five predefined words "Current", "Void", "Result", "Precursor", and | |
| 1400 "NONE", to warn against their accidental use as feature or class names. | |
| 1401 | |
| 1402 Setting eiffel_pedantic will enforce adherence to the Eiffel style | |
| 1403 guidelines fairly rigorously (like arbitrary mixes of upper- and | |
| 1404 lowercase letters as well as outdated ways to capitalize keywords). | |
| 1405 | |
| 1406 If you want to use the lower-case version of "Current", "Void", | |
| 1407 "Result", and "Precursor", you can use > | |
| 1408 | |
| 1409 :let eiffel_lower_case_predef=1 | |
| 1410 | |
| 1411 instead of completely turning case-sensitive highlighting off. | |
| 1412 | |
| 1413 Support for ISE's proposed new creation syntax that is already | |
| 1414 experimentally handled by some compilers can be enabled by: > | |
| 1415 | |
| 1416 :let eiffel_ise=1 | |
| 1417 | |
| 237 | 1418 Finally, some vendors support hexadecimal constants. To handle them, add > |
| 7 | 1419 |
| 1420 :let eiffel_hex_constants=1 | |
| 1421 | |
| 1422 to your startup file. | |
| 1423 | |
| 1424 | |
| 5697 | 1425 EUPHORIA *euphoria3.vim* *euphoria4.vim* *ft-euphoria-syntax* |
| 1426 | |
| 21250 | 1427 Two syntax highlighting files exist for Euphoria. One for Euphoria |
| 18831 | 1428 version 3.1.1, which is the default syntax highlighting file, and one for |
| 5697 | 1429 Euphoria version 4.0.5 or later. |
| 1430 | |
| 18831 | 1431 Euphoria version 3.1.1 (http://www.rapideuphoria.com/) is still necessary |
| 1432 for developing applications for the DOS platform, which Euphoria version 4 | |
| 5697 | 1433 (http://www.openeuphoria.org/) does not support. |
| 1434 | |
| 18831 | 1435 The following file extensions are auto-detected as Euphoria file type: |
| 1436 | |
| 5697 | 1437 *.e, *.eu, *.ew, *.ex, *.exu, *.exw |
| 1438 *.E, *.EU, *.EW, *.EX, *.EXU, *.EXW | |
| 1439 | |
| 18831 | 1440 To select syntax highlighting file for Euphoria, as well as for |
| 5697 | 1441 auto-detecting the *.e and *.E file extensions as Euphoria file type, |
| 1442 add the following line to your startup file: > | |
| 1443 | |
| 25161 | 1444 :let g:filetype_euphoria = "euphoria3" |
| 25056 | 1445 |
| 1446 < or > | |
| 1447 | |
| 25161 | 1448 :let g:filetype_euphoria = "euphoria4" |
| 1449 | |
| 27036 | 1450 Elixir and Euphoria share the *.ex file extension. If the filetype is |
| 25161 | 1451 specifically set as Euphoria with the g:filetype_euphoria variable, or the |
| 1452 file is determined to be Euphoria based on keywords in the file, then the | |
| 1453 filetype will be set as Euphoria. Otherwise, the filetype will default to | |
| 1454 Elixir. | |

1491 NOTE: This site currently doesn't work, on Wikipedia is mentioned that |
| 2826 | 1492 development stopped in 2009. |
| 857 | 1493 |
| 1494 Syntax highlighting is available for the most common elements of FlexWiki | |
| 1495 syntax. The associated ftplugin script sets some buffer-local options to make | |
| 1496 editing FlexWiki pages more convenient. FlexWiki considers a newline as the | |
| 1497 start of a new paragraph, so the ftplugin sets 'tw'=0 (unlimited line length), | |
| 1498 'wrap' (wrap long lines instead of using horizontal scrolling), 'linebreak' | |
| 1499 (to wrap at a character in 'breakat' instead of at the last char on screen), | |
| 1500 and so on. It also includes some keymaps that are disabled by default. | |
| 1501 | |
| 1502 If you want to enable the keymaps that make "j" and "k" and the cursor keys | |
| 1503 move up and down by display lines, add this to your .vimrc: > | |

| 7 | 1512 J.A.M. Vermaseren, CAN, Netherlands, 1991. |
| 1513 | |
| 1514 If you want include your own changes to the default colors, you have to | |
| 1515 redefine the following syntax groups: | |
| 1516 | |
| 1517 - formConditional | |
| 1518 - formNumber | |
| 1519 - formStatement | |
| 1520 - formHeaderStatement | |
| 1521 - formComment | |
| 1522 - formPreProc | |
| 1523 - formDirective | |
| 1524 - formType | |
| 1525 - formString | |
| 1526 | |
| 1527 Note that the form.vim syntax file implements FORM preprocessor commands and | |
| 1528 directives per default in the same syntax group. | |
| 1529 | |
| 1530 A predefined enhanced color mode for FORM is available to distinguish between | |
| 237 | 1531 header statements and statements in the body of a FORM program. To activate |
| 7 | 1532 this mode define the following variable in your vimrc file > |
| 1533 | |
| 1534 :let form_enhanced_color=1 | |
| 1535 | |
| 1536 The enhanced mode also takes advantage of additional color features for a dark | |
| 237 | 1537 gvim display. Here, statements are colored LightYellow instead of Yellow, and |
| 7 | 1538 conditionals are LightBlue for better distinction. |
| 1539 | |
| 27537 | 1540 Both Visual Basic and FORM use the extension ".frm". To detect which one |
| 1541 should be used, Vim checks for the string "VB_Name" in the first five lines of | |
| 1542 the file. If it is found, filetype will be "vb", otherwise "form". | |
| 1543 | |
| 1544 If the automatic detection doesn't work for you or you only edit, for | |
| 1545 example, FORM files, use this in your startup vimrc: > | |
| 1546 :let filetype_frm = "form" | |

| 1559 Default highlighting and dialect ~ | |
| 3256 | 1560 Highlighting appropriate for Fortran 2008 is used by default. This choice |
| 4992 | 1561 should be appropriate for most users most of the time because Fortran 2008 is |

| 7 | 1597 |
| 1598 Tabs in fortran files ~ | |
| 237 | 1599 Tabs are not recognized by the Fortran standards. Tabs are not a good idea in |
| 7 | 1600 fixed format fortran source code which requires fixed column boundaries. |
| 237 | 1601 Therefore, tabs are marked as errors. Nevertheless, some programmers like |
| 1602 using tabs. If your fortran files contain tabs, then you should set the | |
| 7 | 1603 variable fortran_have_tabs in your .vimrc with a command such as > |
| 1604 :let fortran_have_tabs=1 | |
| 237 | 1605 placed prior to the :syntax on command. Unfortunately, the use of tabs will |
| 7 | 1606 mean that the syntax file will not be able to detect incorrect margins. |
| 1607 | |
| 1608 Syntax folding of fortran files ~ | |
| 1609 If you wish to use foldmethod=syntax, then you must first set the variable | |
| 1610 fortran_fold with a command such as > | |
| 1611 :let fortran_fold=1 | |
| 1612 to instruct the syntax script to define fold regions for program units, that | |
| 1613 is main programs starting with a program statement, subroutines, function | |
| 237 | 1614 subprograms, block data subprograms, interface blocks, and modules. If you |
| 7 | 1615 also set the variable fortran_fold_conditionals with a command such as > |
| 1616 :let fortran_fold_conditionals=1 | |
| 1617 then fold regions will also be defined for do loops, if blocks, and select | |
| 237 | 1618 case constructs. If you also set the variable |
| 7 | 1619 fortran_fold_multilinecomments with a command such as > |
| 1620 :let fortran_fold_multilinecomments=1 | |
| 1621 then fold regions will also be defined for three or more consecutive comment | |
| 237 | 1622 lines. Note that defining fold regions can be slow for large files. |
| 7 | 1623 |
| 1624 If fortran_fold, and possibly fortran_fold_conditionals and/or | |
| 1625 fortran_fold_multilinecomments, have been set, then vim will fold your file if | |
| 237 | 1626 you set foldmethod=syntax. Comments or blank lines placed between two program |
| 7 | 1627 units are not folded because they are seen as not belonging to any program |
| 1628 unit. | |
| 1629 | |
| 1630 More precise fortran syntax ~ | |
| 1631 If you set the variable fortran_more_precise with a command such as > | |
| 1632 :let fortran_more_precise=1 | |
| 237 | 1633 then the syntax coloring will be more precise but slower. In particular, |
| 7 | 1634 statement labels used in do, goto and arithmetic if statements will be |
| 1635 recognized, as will construct names at the end of a do, if, select or forall | |
| 1636 construct. | |
| 1637 | |
| 1638 Non-default fortran dialects ~ | |
| 3281 | 1639 The syntax script supports two Fortran dialects: f08 and F. You will probably |
| 1640 find the default highlighting (f08) satisfactory. A few legacy constructs | |
| 1641 deleted or declared obsolescent in the 2008 standard are highlighted as todo | |
| 1642 items. | |
| 1643 | |
| 1644 If you use F, the advantage of setting the dialect appropriately is that | |
| 1645 other legacy features excluded from F will be highlighted as todo items and | |
| 4992 | 1646 that free source form will be assumed. |
| 3281 | 1647 |
| 1648 The dialect can be selected in various ways. If all your fortran files use | |
| 1649 the same dialect, set the global variable fortran_dialect in your .vimrc prior | |
| 1650 to your syntax on statement. The case-sensitive, permissible values of | |
| 1651 fortran_dialect are "f08" or "F". Invalid values of fortran_dialect are | |
| 1652 ignored. | |
| 1653 | |
| 1654 If the dialect depends upon the file extension, then it is most convenient to | |
| 1655 set a buffer-local variable in a ftplugin file. For more information on | |
| 1656 ftplugin files, see |ftplugin|. For example, if all your fortran files with | |
| 1657 an .f90 extension are written in the F subset, your ftplugin file should | |
| 1658 contain the code > | |
| 7 | 1659 let s:extfname = expand("%:e") |
| 1660 if s:extfname ==? "f90" | |
| 3281 | 1661 let b:fortran_dialect="F" |
| 7 | 1662 else |
| 3281 | 1663 unlet! b:fortran_dialect |
| 7 | 1664 endif |
| 1665 Note that this will work only if the "filetype plugin indent on" command | |
| 1666 precedes the "syntax on" command in your .vimrc file. | |
| 1667 | |
| 1668 Finer control is necessary if the file extension does not uniquely identify | |
| 3281 | 1669 the dialect. You can override the default dialect, on a file-by-file basis, |
| 1670 by including a comment with the directive "fortran_dialect=xx" (where xx=F or | |
| 1671 f08) in one of the first three lines in your file. For example, your older .f | |
| 1672 files may be legacy code but your newer ones may be F codes, and you would | |
| 1673 identify the latter by including in the first three lines of those files a | |
| 1674 Fortran comment of the form > | |
| 7 | 1675 ! fortran_dialect=F |
| 3281 | 1676 |
| 1677 For previous versions of the syntax, you may have set fortran_dialect to the | |
| 1678 now-obsolete values "f77", "f90", "f95", or "elf". Such settings will be | |
| 1679 silently handled as "f08". Users of "elf" may wish to experiment with "F" | |
| 4992 | 1680 instead. |
| 3281 | 1681 |
| 1682 The syntax/fortran.vim script contains embedded comments that tell you how to | |
| 1683 comment and/or uncomment some lines to (a) activate recognition of some | |
| 1684 non-standard, vendor-supplied intrinsics and (b) to prevent features deleted | |
| 1685 or declared obsolescent in the 2008 standard from being highlighted as todo | |
| 4992 | 1686 items. |
| 7 | 1687 |
| 1688 Limitations ~ | |
| 237 | 1689 Parenthesis checking does not catch too few closing parentheses. Hollerith |
| 1690 strings are not recognized. Some keywords may be highlighted incorrectly | |
| 7 | 1691 because Fortran90 has no reserved words. |
| 1692 | |
| 501 | 1693 For further information related to fortran, see |ft-fortran-indent| and |
| 1694 |ft-fortran-plugin|. | |
| 1695 | |
| 1696 | |
| 1697 FVWM CONFIGURATION FILES *fvwm.vim* *ft-fvwm-syntax* | |
| 7 | 1698 |
| 1699 In order for Vim to recognize Fvwm configuration files that do not match | |
| 1700 the patterns *fvwmrc* or *fvwm2rc* , you must put additional patterns | |
| 1701 appropriate to your system in your myfiletypes.vim file. For these | |
| 1702 patterns, you must set the variable "b:fvwm_version" to the major version | |
| 1703 number of Fvwm, and the 'filetype' option to fvwm. | |
| 1704 | |
| 1705 For example, to make Vim identify all files in /etc/X11/fvwm2/ | |
| 1706 as Fvwm2 configuration files, add the following: > | |
| 1707 | |
| 1708 :au! BufNewFile,BufRead /etc/X11/fvwm2/* let b:fvwm_version = 2 | | |
| 1709 \ set filetype=fvwm | |
| 1710 | |
| 501 | 1711 GSP *gsp.vim* *ft-gsp-syntax* |
| 7 | 1712 |
| 1713 The default coloring style for GSP pages is defined by |html.vim|, and | |
| 1714 the coloring for java code (within java tags or inline between backticks) | |
| 1715 is defined by |java.vim|. The following HTML groups defined in |html.vim| | |
| 1716 are redefined to incorporate and highlight inline java code: | |
| 1717 | |
| 1718 htmlString | |
| 1719 htmlValue | |
| 1720 htmlEndTag | |
| 1721 htmlTag | |
| 1722 htmlTagN | |
| 1723 | |
| 1724 Highlighting should look fine most of the places where you'd see inline | |
| 1725 java code, but in some special cases it may not. To add another HTML | |
| 1726 group where you will have inline java code where it does not highlight | |
| 1727 correctly, just copy the line you want from |html.vim| and add gspJava | |
| 1728 to the contains clause. | |
| 1729 | |
| 1730 The backticks for inline java are highlighted according to the htmlError | |
| 1731 group to make them easier to see. | |
| 1732 | |
| 1733 | |
| 501 | 1734 GROFF *groff.vim* *ft-groff-syntax* |
| 7 | 1735 |
| 1736 The groff syntax file is a wrapper for |nroff.vim|, see the notes | |
| 237 | 1737 under that heading for examples of use and configuration. The purpose |
| 7 | 1738 of this wrapper is to set up groff syntax extensions by setting the |
| 1739 filetype from a |modeline| or in a personal filetype definitions file | |
| 1740 (see |filetype.txt|). | |
| 1741 | |
| 1742 | |
| 501 | 1743 HASKELL *haskell.vim* *lhaskell.vim* *ft-haskell-syntax* |
| 7 | 1744 |
| 1745 The Haskell syntax files support plain Haskell code as well as literate | |
| 237 | 1746 Haskell code, the latter in both Bird style and TeX style. The Haskell |
| 7 | 1747 syntax highlighting will also highlight C preprocessor directives. |
| 1748 | |
| 1749 If you want to highlight delimiter characters (useful if you have a | |
| 1750 light-coloured background), add to your .vimrc: > | |
| 1751 :let hs_highlight_delimiters = 1 | |
| 1752 To treat True and False as keywords as opposed to ordinary identifiers, | |
| 1753 add: > | |
| 1754 :let hs_highlight_boolean = 1 | |
| 1755 To also treat the names of primitive types as keywords: > | |
| 1756 :let hs_highlight_types = 1 | |
| 1757 And to treat the names of even more relatively common types as keywords: > | |
| 1758 :let hs_highlight_more_types = 1 | |
| 1759 If you want to highlight the names of debugging functions, put in | |
| 1760 your .vimrc: > | |
| 1761 :let hs_highlight_debug = 1 | |
| 1762 | |
| 1763 The Haskell syntax highlighting also highlights C preprocessor | |
| 1764 directives, and flags lines that start with # but are not valid | |
| 237 | 1765 directives as erroneous. This interferes with Haskell's syntax for |
| 1766 operators, as they may start with #. If you want to highlight those | |
| 7 | 1767 as operators as opposed to errors, put in your .vimrc: > |
| 1768 :let hs_allow_hash_operator = 1 | |
| 1769 | |
| 1770 The syntax highlighting for literate Haskell code will try to | |
| 1771 automatically guess whether your literate Haskell code contains | |
| 1772 TeX markup or not, and correspondingly highlight TeX constructs | |
| 237 | 1773 or nothing at all. You can override this globally by putting |
| 7 | 1774 in your .vimrc > |
| 1775 :let lhs_markup = none | |
| 1776 for no highlighting at all, or > | |
| 1777 :let lhs_markup = tex | |
| 1778 to force the highlighting to always try to highlight TeX markup. | |
| 1779 For more flexibility, you may also use buffer local versions of | |
| 1780 this variable, so e.g. > | |
| 1781 :let b:lhs_markup = tex | |
| 237 | 1782 will force TeX highlighting for a particular buffer. It has to be |
| 7 | 1783 set before turning syntax highlighting on for the buffer or |
| 1784 loading a file. | |
| 1785 | |
| 1786 | |
| 501 | 1787 HTML *html.vim* *ft-html-syntax* |
| 7 | 1788 |
| 1789 The coloring scheme for tags in the HTML file works as follows. | |
| 1790 | |
| 1791 The <> of opening tags are colored differently than the </> of a closing tag. | |
| 1792 This is on purpose! For opening tags the 'Function' color is used, while for | |
| 24103 | 1793 closing tags the 'Identifier' color is used (See syntax.vim to check how those |
| 1794 are defined for you) | |
| 7 | 1795 |
| 1796 Known tag names are colored the same way as statements in C. Unknown tag | |
| 1797 names are colored with the same color as the <> or </> respectively which | |
| 1798 makes it easy to spot errors | |
| 1799 | |
| 237 | 1800 Note that the same is true for argument (or attribute) names. Known attribute |
| 7 | 1801 names are colored differently than unknown ones. |
| 1802 | |
| 237 | 1803 Some HTML tags are used to change the rendering of text. The following tags |
| 7 | 1804 are recognized by the html.vim syntax coloring file and change the way normal |
| 1805 text is shown: <B> <I> <U> <EM> <STRONG> (<EM> is used as an alias for <I>, | |
| 1806 while <STRONG> as an alias for <B>), <H1> - <H6>, <HEAD>, <TITLE> and <A>, but | |
| 237 | 1807 only if used as a link (that is, it must include a href as in |
| 1224 | 1808 <A href="somefile.html">). |
| 7 | 1809 |
| 1810 If you want to change how such text is rendered, you must redefine the | |
| 1811 following syntax groups: | |
| 1812 | |
| 1813 - htmlBold | |
| 1814 - htmlBoldUnderline | |
| 1815 - htmlBoldUnderlineItalic | |
| 1816 - htmlUnderline | |
| 1817 - htmlUnderlineItalic | |
| 1818 - htmlItalic | |
| 1819 - htmlTitle for titles | |
| 1820 - htmlH1 - htmlH6 for headings | |
| 1821 | |
| 1822 To make this redefinition work you must redefine them all with the exception | |
| 1823 of the last two (htmlTitle and htmlH[1-6], which are optional) and define the | |
| 1824 following variable in your vimrc (this is due to the order in which the files | |
| 1825 are read during initialization) > | |
| 1826 :let html_my_rendering=1 | |
| 1827 | |
| 1828 If you'd like to see an example download mysyntax.vim at | |
| 1829 http://www.fleiner.com/vim/download.html | |
| 1830 | |
| 1831 You can also disable this rendering by adding the following line to your | |
| 1832 vimrc file: > | |
| 1833 :let html_no_rendering=1 | |
| 1834 | |
| 1835 HTML comments are rather special (see an HTML reference document for the | |
| 1836 details), and the syntax coloring scheme will highlight all errors. | |
| 1837 However, if you prefer to use the wrong style (starts with <!-- and | |

1844 currently supported, no other scripting language has been added yet. |
| 7 | 1845 |
| 1846 Embedded and inlined cascading style sheets (CSS) are highlighted too. | |
| 1847 | |
| 237 | 1848 There are several html preprocessor languages out there. html.vim has been |
| 1849 written such that it should be trivial to include it. To do so add the | |
| 7 | 1850 following two lines to the syntax coloring file for that language |
| 1851 (the example comes from the asp.vim file): | |
| 18016 | 1852 > |
| 7 | 1853 runtime! syntax/html.vim |
| 1854 syn cluster htmlPreproc add=asp | |
| 1855 | |
| 1856 Now you just need to make sure that you add all regions that contain | |
| 1857 the preprocessor language to the cluster htmlPreproc. | |
| 1858 | |
| 1859 | |
| 501 | 1860 HTML/OS (by Aestiva) *htmlos.vim* *ft-htmlos-syntax* |
| 7 | 1861 |
| 1862 The coloring scheme for HTML/OS works as follows: | |
| 1863 | |
| 1864 Functions and variable names are the same color by default, because VIM | |
| 1865 doesn't specify different colors for Functions and Identifiers. To change | |
| 1866 this (which is recommended if you want function names to be recognizable in a | |
| 1867 different color) you need to add the following line to either your ~/.vimrc: > | |
| 1868 :hi Function term=underline cterm=bold ctermfg=LightGray | |
| 1869 | |
| 1870 Of course, the ctermfg can be a different color if you choose. | |
| 1871 | |
| 1872 Another issues that HTML/OS runs into is that there is no special filetype to | |
| 1873 signify that it is a file with HTML/OS coding. You can change this by opening | |
| 1874 a file and turning on HTML/OS syntax by doing the following: > | |
| 1875 :set syntax=htmlos | |
| 1876 | |
| 1877 Lastly, it should be noted that the opening and closing characters to begin a | |
| 1878 block of HTML/OS code can either be << or [[ and >> or ]], respectively. | |
| 1879 | |
| 1880 | |
| 501 | 1881 IA64 *ia64.vim* *intel-itanium* *ft-ia64-syntax* |
| 7 | 1882 |
| 1883 Highlighting for the Intel Itanium 64 assembly language. See |asm.vim| for | |
| 1884 how to recognize this filetype. | |
| 1885 | |
| 1886 To have *.inc files be recognized as IA64, add this to your .vimrc file: > | |
| 1887 :let g:filetype_inc = "ia64" | |
| 1888 | |
| 1889 | |
| 501 | 1890 INFORM *inform.vim* *ft-inform-syntax* |
| 7 | 1891 |
| 1892 Inform highlighting includes symbols provided by the Inform Library, as | |
| 1893 most programs make extensive use of it. If do not wish Library symbols | |
| 1894 to be highlighted add this to your vim startup: > | |
| 1895 :let inform_highlight_simple=1 | |
| 1896 | |
| 1897 By default it is assumed that Inform programs are Z-machine targeted, | |
| 1898 and highlights Z-machine assembly language symbols appropriately. If | |
| 1899 you intend your program to be targeted to a Glulx/Glk environment you | |
| 1900 need to add this to your startup sequence: > | |
| 1901 :let inform_highlight_glulx=1 | |
| 1902 | |
| 1903 This will highlight Glulx opcodes instead, and also adds glk() to the | |
| 1904 set of highlighted system functions. | |
| 1905 | |
| 1906 The Inform compiler will flag certain obsolete keywords as errors when | |
| 1907 it encounters them. These keywords are normally highlighted as errors | |
| 1908 by Vim. To prevent such error highlighting, you must add this to your | |
| 1909 startup sequence: > | |
| 1910 :let inform_suppress_obsolete=1 | |
| 1911 | |
| 1912 By default, the language features highlighted conform to Compiler | |
| 1913 version 6.30 and Library version 6.11. If you are using an older | |
| 1914 Inform development environment, you may with to add this to your | |
| 1915 startup sequence: > | |
| 1916 :let inform_highlight_old=1 | |
| 1917 | |
| 829 | 1918 IDL *idl.vim* *idl-syntax* |
| 1919 | |
| 1920 IDL (Interface Definition Language) files are used to define RPC calls. In | |
| 1921 Microsoft land, this is also used for defining COM interfaces and calls. | |
| 1922 | |
| 1923 IDL's structure is simple enough to permit a full grammar based approach to | |
| 1924 rather than using a few heuristics. The result is large and somewhat | |
| 1224 | 1925 repetitive but seems to work. |
| 829 | 1926 |
| 1927 There are some Microsoft extensions to idl files that are here. Some of them | |
| 1928 are disabled by defining idl_no_ms_extensions. | |
| 1929 | |
| 1930 The more complex of the extensions are disabled by defining idl_no_extensions. | |
| 1931 | |
| 1932 Variable Effect ~ | |
| 1933 | |
| 1934 idl_no_ms_extensions Disable some of the Microsoft specific | |
| 1935 extensions | |
| 1936 idl_no_extensions Disable complex extensions | |

| 1944 The java.vim syntax highlighting file offers several options: | |
| 1945 | |
| 1946 In Java 1.0.2 it was never possible to have braces inside parens, so this was | |
| 1947 flagged as an error. Since Java 1.1 this is possible (with anonymous | |

1949 old way, put the following line into your vim startup file: > |
| 7 | 1950 :let java_mark_braces_in_parens_as_errors=1 |
| 1951 | |
| 1952 All identifiers in java.lang.* are always visible in all classes. To | |
| 1953 highlight them use: > | |
| 1954 :let java_highlight_java_lang_ids=1 | |
| 1955 | |
| 237 | 1956 You can also highlight identifiers of most standard Java packages if you |
| 7 | 1957 download the javaid.vim script at http://www.fleiner.com/vim/download.html. |
| 1958 If you prefer to only highlight identifiers of a certain package, say java.io | |
| 1959 use the following: > | |
| 1960 :let java_highlight_java_io=1 | |
| 1961 Check the javaid.vim file for a list of all the packages that are supported. | |
| 1962 | |
| 1963 Function names are not highlighted, as the way to find functions depends on | |
| 237 | 1964 how you write Java code. The syntax file knows two possible ways to highlight |
| 7 | 1965 functions: |
| 1966 | |
| 1967 If you write function declarations that are always indented by either | |
| 1968 a tab, 8 spaces or 2 spaces you may want to set > | |
| 1969 :let java_highlight_functions="indent" | |
| 1970 However, if you follow the Java guidelines about how functions and classes are | |
| 1971 supposed to be named (with respect to upper and lowercase), use > | |
| 1972 :let java_highlight_functions="style" | |
| 1973 If both options do not work for you, but you would still want function | |
| 1974 declarations to be highlighted create your own definitions by changing the | |
| 1975 definitions in java.vim or by creating your own java.vim which includes the | |
| 1976 original one and then adds the code to highlight functions. | |
| 1977 | |
| 237 | 1978 In Java 1.1 the functions System.out.println() and System.err.println() should |
| 8 | 1979 only be used for debugging. Therefore it is possible to highlight debugging |
| 237 | 1980 statements differently. To do this you must add the following definition in |
| 7 | 1981 your startup file: > |
| 1982 :let java_highlight_debug=1 | |
| 1983 The result will be that those statements are highlighted as 'Special' | |
| 237 | 1984 characters. If you prefer to have them highlighted differently you must define |
| 7 | 1985 new highlightings for the following groups.: |
| 1986 Debug, DebugSpecial, DebugString, DebugBoolean, DebugType | |
| 1987 which are used for the statement itself, special characters used in debug | |
| 237 | 1988 strings, strings, boolean constants and types (this, super) respectively. I |
| 21499 | 1989 have opted to choose another background for those statements. |
| 7 | 1990 |
| 237 | 1991 Javadoc is a program that takes special comments out of Java program files and |
| 1992 creates HTML pages. The standard configuration will highlight this HTML code | |
| 1993 similarly to HTML files (see |html.vim|). You can even add Javascript | |
| 1994 and CSS inside this code (see below). There are four differences however: | |
| 7 | 1995 1. The title (all characters up to the first '.' which is followed by |
| 1996 some white space or up to the first '@') is colored differently (to change | |
| 1997 the color change the group CommentTitle). | |
| 1998 2. The text is colored as 'Comment'. | |
| 1999 3. HTML comments are colored as 'Special' | |
| 237 | 2000 4. The special Javadoc tags (@see, @param, ...) are highlighted as specials |
| 7 | 2001 and the argument (for @see, @param, @exception) as Function. |
| 2002 To turn this feature off add the following line to your startup file: > | |
| 2003 :let java_ignore_javadoc=1 | |
| 2004 | |
| 237 | 2005 If you use the special Javadoc comment highlighting described above you |
| 2006 can also turn on special highlighting for Javascript, visual basic | |
| 2007 scripts and embedded CSS (stylesheets). This makes only sense if you | |
| 2008 actually have Javadoc comments that include either Javascript or embedded | |
| 2009 CSS. The options to use are > | |
| 7 | 2010 :let java_javascript=1 |
| 2011 :let java_css=1 | |
| 2012 :let java_vb=1 | |
| 2013 | |
| 2014 In order to highlight nested parens with different colors define colors | |
| 2015 for javaParen, javaParen1 and javaParen2, for example with > | |
| 2016 :hi link javaParen Comment | |
| 2017 or > | |
| 2018 :hi javaParen ctermfg=blue guifg=#0000ff | |
| 2019 | |
| 2020 If you notice highlighting errors while scrolling backwards, which are fixed | |
| 2021 when redrawing with CTRL-L, try setting the "java_minlines" internal variable | |
| 2022 to a larger number: > | |
| 2023 :let java_minlines = 50 | |
| 2024 This will make the syntax synchronization start 50 lines before the first | |
| 2025 displayed line. The default value is 10. The disadvantage of using a larger | |
| 2026 number is that redrawing can become slow. | |
| 2027 | |
| 2028 | |
| 18130 | 2029 JSON *json.vim* *ft-json-syntax* |
| 2030 | |
| 2031 The json syntax file provides syntax highlighting with conceal support by | |
| 2032 default. To disable concealment: > | |
| 2033 let g:vim_json_conceal = 0 | |
| 2034 | |
| 2035 To disable syntax highlighting of errors: > | |
| 2036 let g:vim_json_warnings = 0 | |

| 501 | 2039 LACE *lace.vim* *ft-lace-syntax* |
| 7 | 2040 |
| 2041 Lace (Language for Assembly of Classes in Eiffel) is case insensitive, but the | |
| 2042 style guide lines are not. If you prefer case insensitive highlighting, just | |
| 2043 define the vim variable 'lace_case_insensitive' in your startup file: > | |
| 2044 :let lace_case_insensitive=1 | |
| 2045 | |
| 2046 | |
| 501 | 2047 LEX *lex.vim* *ft-lex-syntax* |
| 7 | 2048 |
| 2049 Lex uses brute-force synchronizing as the "^%%$" section delimiter | |
| 2050 gives no clue as to what section follows. Consequently, the value for > | |
| 2051 :syn sync minlines=300 | |
| 2052 may be changed by the user if s/he is experiencing synchronization | |
| 2053 difficulties (such as may happen with large lex files). | |

| 2073 < | |
| 2074 The g:lisp_rainbow option provides 10 levels of individual colorization for | |
| 2075 the parentheses and backquoted parentheses. Because of the quantity of | |
| 2076 colorization levels, unlike non-rainbow highlighting, the rainbow mode | |
| 2077 specifies its highlighting using ctermfg and guifg, thereby bypassing the | |
| 16208 | 2078 usual color scheme control using standard highlighting groups. The actual |

| 501 | 2096 LPC *lpc.vim* *ft-lpc-syntax* |
| 7 | 2097 |
| 14123 | 2098 LPC stands for a simple, memory-efficient language: Lars Pensjö C. The |
| 7 | 2099 file name of LPC is usually *.c. Recognizing these files as LPC would bother |
| 2100 users writing only C programs. If you want to use LPC syntax in Vim, you | |
| 2101 should set a variable in your .vimrc file: > | |
| 2102 | |
| 2103 :let lpc_syntax_for_c = 1 | |
| 2104 | |
| 2105 If it doesn't work properly for some particular C or LPC files, use a | |
| 2106 modeline. For a LPC file: | |
| 2107 | |
| 2108 // vim:set ft=lpc: | |
| 2109 | |
| 2110 For a C file that is recognized as LPC: | |
| 2111 | |
| 2112 // vim:set ft=c: | |
| 2113 | |
| 2114 If you don't want to set the variable, use the modeline in EVERY LPC file. | |
| 2115 | |
| 2116 There are several implementations for LPC, we intend to support most widely | |
| 237 | 2117 used ones. Here the default LPC syntax is for MudOS series, for MudOS v22 |
| 7 | 2118 and before, you should turn off the sensible modifiers, and this will also |
| 5814 | 2119 assert the new efuns after v22 to be invalid, don't set this variable when |
| 7 | 2120 you are using the latest version of MudOS: > |
| 2121 | |
| 2122 :let lpc_pre_v22 = 1 | |
| 2123 | |
| 2124 For LpMud 3.2 series of LPC: > | |
| 2125 | |
| 2126 :let lpc_compat_32 = 1 | |
| 2127 | |
| 2128 For LPC4 series of LPC: > | |
| 2129 | |
| 2130 :let lpc_use_lpc4_syntax = 1 | |
| 2131 | |
| 2132 For uLPC series of LPC: | |
| 2133 uLPC has been developed to Pike, so you should use Pike syntax | |
| 2134 instead, and the name of your source file should be *.pike | |

| 3356 | 2139 The Lua syntax file can be used for versions 4.0, 5.0, 5.1 and 5.2 (5.2 is |
| 838 | 2140 the default). You can select one of these versions using the global variables |
| 2141 lua_version and lua_subversion. For example, to activate Lua | |
| 3356 | 2142 5.1 syntax highlighting, set the variables like this: |
| 838 | 2143 |

| 501 | 2148 MAIL *mail.vim* *ft-mail.vim* |
| 7 | 2149 |
| 2150 Vim highlights all the standard elements of an email (headers, signatures, | |
| 237 | 2151 quoted text and URLs / email addresses). In keeping with standard conventions, |
| 7 | 2152 signatures begin in a line containing only "--" followed optionally by |
| 2153 whitespaces and end with a newline. | |
| 2154 | |
| 2155 Vim treats lines beginning with ']', '}', '|', '>' or a word followed by '>' | |
| 237 | 2156 as quoted text. However Vim highlights headers and signatures in quoted text |
| 7 | 2157 only if the text is quoted with '>' (optionally followed by one space). |
| 2158 | |
| 2159 By default mail.vim synchronises syntax to 100 lines before the first | |
| 237 | 2160 displayed line. If you have a slow machine, and generally deal with emails |
| 7 | 2161 with short headers, you can change this to a smaller value: > |
| 2162 | |
| 2163 :let mail_minlines = 30 | |
| 2164 | |
| 2165 | |
| 501 | 2166 MAKE *make.vim* *ft-make-syntax* |
| 7 | 2167 |
| 2168 In makefiles, commands are usually highlighted to make it easy for you to spot | |
| 2169 errors. However, this may be too much coloring for you. You can turn this | |
| 2170 feature off by using: > | |
| 2171 | |
| 2172 :let make_no_commands = 1 | |
| 2173 | |
| 2174 | |
| 501 | 2175 MAPLE *maple.vim* *ft-maple-syntax* |
| 7 | 2176 |
| 2177 Maple V, by Waterloo Maple Inc, supports symbolic algebra. The language | |
| 2178 supports many packages of functions which are selectively loaded by the user. | |
| 2179 The standard set of packages' functions as supplied in Maple V release 4 may be | |
| 2180 highlighted at the user's discretion. Users may place in their .vimrc file: > | |
| 2181 | |
| 2182 :let mvpkg_all= 1 | |
| 2183 | |
| 2184 to get all package functions highlighted, or users may select any subset by | |
| 2185 choosing a variable/package from the table below and setting that variable to | |
| 2186 1, also in their .vimrc file (prior to sourcing | |
| 2187 $VIMRUNTIME/syntax/syntax.vim). | |

| 28620 | 2200 MARKDOWN *ft-markdown-syntax* |
| 2201 | |
| 2202 If you have long regions there might be wrong highlighting. At the cost of | |
| 2203 slowing down displaying, you can have the engine look further back to sync on | |
| 2204 the start of a region, for example 500 lines: > | |
| 2205 | |
| 2206 :let g:markdown_minlines = 500 | |
| 2207 | |

| 271 | 2210 |

| 2215 | |
| 2216 | |
| 501 | 2217 MOO *moo.vim* *ft-moo-syntax* |
| 7 | 2218 |
| 2219 If you use C-style comments inside expressions and find it mangles your | |
| 2220 highlighting, you may want to use extended (slow!) matches for C-style | |
| 2221 comments: > | |

| 2238 To highlight builtin properties (.name, .location, .programmer etc.): > | |
| 2239 | |
| 2240 :let moo_builtin_properties = 1 | |
| 2241 | |
| 237 | 2242 Unknown builtin functions can be recognized and highlighted as errors. If you |
| 7 | 2243 use this option, add your own extensions to the mooKnownBuiltinFunction group. |
| 2244 To enable this option: > | |
| 2245 | |
| 2246 :let moo_unknown_builtin_functions = 1 | |

| 2251 | |
| 2252 | |
| 501 | 2253 MSQL *msql.vim* *ft-msql-syntax* |
| 7 | 2254 |
| 2255 There are two options for the msql syntax highlighting. | |
| 2256 | |
| 2257 If you like SQL syntax highlighting inside Strings, use this: > | |
| 2258 | |
| 2259 :let msql_sql_query = 1 | |
| 2260 | |
| 2261 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 2262 set "msql_minlines" to the value you desire. Example: > | |
| 2263 | |
| 2264 :let msql_minlines = 200 | |
| 2265 | |
| 2266 | |
| 12254 | 2267 N1QL *n1ql.vim* *ft-n1ql-syntax* |
| 2268 | |
| 2269 N1QL is a SQL-like declarative language for manipulating JSON documents in | |
| 2270 Couchbase Server databases. | |
| 2271 | |
| 2272 Vim syntax highlights N1QL statements, keywords, operators, types, comments, | |
| 2273 and special values. Vim ignores syntactical elements specific to SQL or its | |
| 2274 many dialects, like COLUMN or CHAR, that don't exist in N1QL. | |
| 2275 | |
| 2276 | |
| 501 | 2277 NCF *ncf.vim* *ft-ncf-syntax* |
| 7 | 2278 |
| 2279 There is one option for NCF syntax highlighting. | |
| 2280 | |
| 2281 If you want to have unrecognized (by ncf.vim) statements highlighted as | |
| 2282 errors, use this: > | |
| 2283 | |
| 2284 :let ncf_highlight_unknowns = 1 | |
| 2285 | |
| 2286 If you don't want to highlight these errors, leave it unset. | |
| 2287 | |
| 2288 | |
| 501 | 2289 NROFF *nroff.vim* *ft-nroff-syntax* |
| 7 | 2290 |
| 2291 The nroff syntax file works with AT&T n/troff out of the box. You need to | |
| 2292 activate the GNU groff extra features included in the syntax file before you | |
| 2293 can use them. | |
| 2294 | |
| 2295 For example, Linux and BSD distributions use groff as their default text | |
| 237 | 2296 processing package. In order to activate the extra syntax highlighting |
| 24278 | 2297 features for groff, arrange for files to be recognized as groff (see |
| 2298 |ft-groff-syntax|) or add the following option to your start-up files: > | |
| 2299 | |
| 2300 :let nroff_is_groff = 1 | |
| 7 | 2301 |
| 2302 Groff is different from the old AT&T n/troff that you may still find in | |
| 2303 Solaris. Groff macro and request names can be longer than 2 characters and | |
| 2304 there are extensions to the language primitives. For example, in AT&T troff | |
| 237 | 2305 you access the year as a 2-digit number with the request \(yr. In groff you |
| 7 | 2306 can use the same request, recognized for compatibility, or you can use groff's |
| 2307 native syntax, \[yr]. Furthermore, you can use a 4-digit year directly: | |
| 2308 \[year]. Macro requests can be longer than 2 characters, for example, GNU mm | |
| 2309 accepts the requests ".VERBON" and ".VERBOFF" for creating verbatim | |
| 2310 environments. | |
| 2311 | |
| 2312 In order to obtain the best formatted output g/troff can give you, you should | |
| 2313 follow a few simple rules about spacing and punctuation. | |
| 2314 | |
| 2315 1. Do not leave empty spaces at the end of lines. | |
| 2316 | |
| 2317 2. Leave one space and one space only after an end-of-sentence period, | |
| 2318 exclamation mark, etc. | |
| 2319 | |
| 2320 3. For reasons stated below, it is best to follow all period marks with a | |
| 2321 carriage return. | |
| 2322 | |
| 2323 The reason behind these unusual tips is that g/n/troff have a line breaking | |
| 2324 algorithm that can be easily upset if you don't follow the rules given above. | |
| 2325 | |
| 2326 Unlike TeX, troff fills text line-by-line, not paragraph-by-paragraph and, | |
| 2327 furthermore, it does not have a concept of glue or stretch, all horizontal and | |
| 2328 vertical space input will be output as is. | |
| 2329 | |
| 2330 Therefore, you should be careful about not using more space between sentences | |
| 2331 than you intend to have in your final document. For this reason, the common | |
| 2332 practice is to insert a carriage return immediately after all punctuation | |
| 237 | 2333 marks. If you want to have "even" text in your final processed output, you |
| 4264 | 2334 need to maintain regular spacing in the input text. To mark both trailing |
| 7 | 2335 spaces and two or more spaces after a punctuation as an error, use: > |
| 2336 | |
| 2337 :let nroff_space_errors = 1 | |
| 2338 | |
| 2339 Another technique to detect extra spacing and other errors that will interfere | |
| 2340 with the correct typesetting of your file, is to define an eye-catching | |
| 2341 highlighting definition for the syntax groups "nroffDefinition" and | |
| 237 | 2342 "nroffDefSpecial" in your configuration files. For example: > |
| 7 | 2343 |
| 2344 hi def nroffDefinition term=italic cterm=italic gui=reverse | |
| 2345 hi def nroffDefSpecial term=italic,bold cterm=italic,bold | |
| 2346 \ gui=reverse,bold | |
| 2347 | |
| 2348 If you want to navigate preprocessor entries in your source file as easily as | |
| 2349 with section markers, you can activate the following option in your .vimrc | |
| 2350 file: > | |
| 2351 | |
| 2352 let b:preprocs_as_sections = 1 | |
| 2353 | |
| 9 | 2354 As well, the syntax file adds an extra paragraph marker for the extended |
| 7 | 2355 paragraph macro (.XP) in the ms package. |
| 2356 | |
| 2357 Finally, there is a |groff.vim| syntax file that can be used for enabling | |
| 2358 groff syntax highlighting either on a file basis or globally by default. | |
| 2359 | |
| 2360 | |
| 501 | 2361 OCAML *ocaml.vim* *ft-ocaml-syntax* |
| 7 | 2362 |
| 2363 The OCaml syntax file handles files having the following prefixes: .ml, | |
| 2364 .mli, .mll and .mly. By setting the following variable > | |
| 2365 | |
| 2366 :let ocaml_revised = 1 | |
| 2367 | |
| 2368 you can switch from standard OCaml-syntax to revised syntax as supported | |
| 2369 by the camlp4 preprocessor. Setting the variable > | |
| 2370 | |
| 2371 :let ocaml_noend_error = 1 | |
| 2372 | |
| 2373 prevents highlighting of "end" as error, which is useful when sources | |
| 2374 contain very long structures that Vim does not synchronize anymore. | |
| 2375 | |
| 2376 | |
| 501 | 2377 PAPP *papp.vim* *ft-papp-syntax* |
| 7 | 2378 |
| 19163 | 2379 The PApp syntax file handles .papp files and, to a lesser extent, .pxml |
| 7 | 2380 and .pxsl files which are all a mixture of perl/xml/html/other using xml |
| 237 | 2381 as the top-level file format. By default everything inside phtml or pxml |
| 2382 sections is treated as a string with embedded preprocessor commands. If | |
| 7 | 2383 you set the variable: > |
| 2384 | |
| 2385 :let papp_include_html=1 | |
| 2386 | |
| 2387 in your startup file it will try to syntax-hilight html code inside phtml | |
| 2388 sections, but this is relatively slow and much too colourful to be able to | |
| 237 | 2389 edit sensibly. ;) |
| 7 | 2390 |
| 2391 The newest version of the papp.vim syntax file can usually be found at | |
| 2392 http://papp.plan9.de. | |
| 2393 | |
| 2394 | |
| 501 | 2395 PASCAL *pascal.vim* *ft-pascal-syntax* |
| 7 | 2396 |
| 23666 | 2397 Files matching "*.p" could be Progress or Pascal and those matching "*.pp" |
| 2398 could be Puppet or Pascal. If the automatic detection doesn't work for you, | |
| 2399 or you only edit Pascal files, use this in your startup vimrc: > | |
| 2400 | |
| 2401 :let filetype_p = "pascal" | |
| 2402 :let filetype_pp = "pascal" | |
| 7 | 2403 |
| 2404 The Pascal syntax file has been extended to take into account some extensions | |
| 2405 provided by Turbo Pascal, Free Pascal Compiler and GNU Pascal Compiler. | |
| 237 | 2406 Delphi keywords are also supported. By default, Turbo Pascal 7.0 features are |
| 7 | 2407 enabled. If you prefer to stick with the standard Pascal keywords, add the |
| 2408 following line to your startup file: > | |
| 2409 | |
| 2410 :let pascal_traditional=1 | |
| 2411 | |
| 2412 To switch on Delphi specific constructions (such as one-line comments, | |
| 2413 keywords, etc): > | |
| 2414 | |
| 2415 :let pascal_delphi=1 | |
| 2416 | |
| 2417 | |
| 2418 The option pascal_symbol_operator controls whether symbol operators such as +, | |
| 2419 *, .., etc. are displayed using the Operator color or not. To colorize symbol | |
| 2420 operators, add the following line to your startup file: > | |
| 2421 | |
| 2422 :let pascal_symbol_operator=1 | |
| 2423 | |
| 2424 Some functions are highlighted by default. To switch it off: > | |
| 2425 | |
| 2426 :let pascal_no_functions=1 | |
| 2427 | |

2428 Furthermore, there are specific variables for some compilers. Besides |
| 7 | 2429 pascal_delphi, there are pascal_gpc and pascal_fpc. Default extensions try to |
| 2430 match Turbo Pascal. > | |
| 2431 | |

| 2438 To ensure that strings are defined on a single line, you can define the | |
| 2439 pascal_one_line_string variable. > | |
| 2440 | |
| 2441 :let pascal_one_line_string=1 | |
| 2442 | |
| 2443 If you dislike <Tab> chars, you can set the pascal_no_tabs variable. Tabs | |
| 2444 will be highlighted as Error. > | |

| 501 | 2450 PERL *perl.vim* *ft-perl-syntax* |
| 7 | 2451 |
| 2452 There are a number of possible options to the perl syntax highlighting. | |
| 2453 | |
| 4992 | 2454 Inline POD highlighting is now turned on by default. If you don't wish |
| 2455 to have the added complexity of highlighting POD embedded within Perl | |
| 2456 files, you may set the 'perl_include_pod' option to 0: > | |
| 2457 | |
| 2458 :let perl_include_pod = 0 | |
| 7 | 2459 |
| 5968 | 2460 To reduce the complexity of parsing (and increase performance) you can switch |
| 22 | 2461 off two elements in the parsing of variable names and contents. > |
| 2462 | |
| 2463 To handle package references in variable and function names not differently | |
| 2464 from the rest of the name (like 'PkgName::' in '$PkgName::VarName'): > | |
| 2465 | |
| 2466 :let perl_no_scope_in_variables = 1 | |
| 2467 | |
| 2468 (In Vim 6.x it was the other way around: "perl_want_scope_in_variables" | |
| 2469 enabled it.) | |
| 2470 | |
| 2471 If you do not want complex things like '@{${"foo"}}' to be parsed: > | |
| 2472 | |
| 2473 :let perl_no_extended_vars = 1 | |
| 2474 | |
| 26 | 2475 (In Vim 6.x it was the other way around: "perl_extended_vars" enabled it.) |

2606 continuation symbols. |
| 7 | 2607 |
| 2608 The default setting for ppwiz_highlight_defs is 1. | |
| 2609 | |
| 2610 - ppwiz_with_html : If the value is 1 (the default), highlight literal | |
| 2611 HTML code; if 0, treat HTML code like ordinary text. | |
| 2612 | |
| 2613 | |
| 501 | 2614 PHTML *phtml.vim* *ft-phtml-syntax* |
| 7 | 2615 |
| 2616 There are two options for the phtml syntax highlighting. | |
| 2617 | |
| 2618 If you like SQL syntax highlighting inside Strings, use this: > | |
| 2619 | |
| 2620 :let phtml_sql_query = 1 | |
| 2621 | |
| 2622 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 2623 set "phtml_minlines" to the value you desire. Example: > | |
| 2624 | |
| 2625 :let phtml_minlines = 200 | |
| 2626 | |
| 2627 | |
| 501 | 2628 POSTSCRIPT *postscr.vim* *ft-postscr-syntax* |
| 7 | 2629 |
| 2630 There are several options when it comes to highlighting PostScript. | |
| 2631 | |
| 2632 First which version of the PostScript language to highlight. There are | |
| 2633 currently three defined language versions, or levels. Level 1 is the original | |
| 2634 and base version, and includes all extensions prior to the release of level 2. | |
| 2635 Level 2 is the most common version around, and includes its own set of | |
| 2636 extensions prior to the release of level 3. Level 3 is currently the highest | |
| 2637 level supported. You select which level of the PostScript language you want | |
| 2638 highlighted by defining the postscr_level variable as follows: > | |
| 2639 | |
| 2640 :let postscr_level=2 | |
| 2641 | |
| 2642 If this variable is not defined it defaults to 2 (level 2) since this is | |
| 2643 the most prevalent version currently. | |

2645 Note: Not all PS interpreters will support all language features for a |
| 7 | 2646 particular language level. In particular the %!PS-Adobe-3.0 at the start of |
| 2647 PS files does NOT mean the PostScript present is level 3 PostScript! | |
| 2648 | |
| 2649 If you are working with Display PostScript, you can include highlighting of | |
| 2650 Display PS language features by defining the postscr_display variable as | |
| 2651 follows: > | |
| 2652 | |
| 2653 :let postscr_display=1 | |
| 2654 | |
| 2655 If you are working with Ghostscript, you can include highlighting of | |
| 2656 Ghostscript specific language features by defining the variable | |
| 2657 postscr_ghostscript as follows: > | |
| 2658 | |
| 2659 :let postscr_ghostscript=1 | |
| 2660 | |
| 2661 PostScript is a large language, with many predefined elements. While it | |
| 2662 useful to have all these elements highlighted, on slower machines this can | |
| 2663 cause Vim to slow down. In an attempt to be machine friendly font names and | |
| 2664 character encodings are not highlighted by default. Unless you are working | |
| 2665 explicitly with either of these this should be ok. If you want them to be | |
| 2666 highlighted you should set one or both of the following variables: > | |
| 2667 | |
| 2668 :let postscr_fonts=1 | |
| 2669 :let postscr_encodings=1 | |
| 2670 | |
| 2671 There is a stylistic option to the highlighting of and, or, and not. In | |
| 2672 PostScript the function of these operators depends on the types of their | |
| 2673 operands - if the operands are booleans then they are the logical operators, | |
| 2674 if they are integers then they are binary operators. As binary and logical | |
| 2675 operators can be highlighted differently they have to be highlighted one way | |
| 2676 or the other. By default they are treated as logical operators. They can be | |
| 2677 highlighted as binary operators by defining the variable | |
| 2678 postscr_andornot_binary as follows: > | |
| 2679 | |
| 2680 :let postscr_andornot_binary=1 | |
| 2681 < | |
| 2682 | |
| 501 | 2683 *ptcap.vim* *ft-printcap-syntax* |
| 2684 PRINTCAP + TERMCAP *ft-ptcap-syntax* *ft-termcap-syntax* | |
| 7 | 2685 |
| 2686 This syntax file applies to the printcap and termcap databases. | |
| 2687 | |
| 2688 In order for Vim to recognize printcap/termcap files that do not match | |
| 2689 the patterns *printcap*, or *termcap*, you must put additional patterns | |
| 2690 appropriate to your system in your |myfiletypefile| file. For these | |
| 2691 patterns, you must set the variable "b:ptcap_type" to either "print" or | |
| 2692 "term", and then the 'filetype' option to ptcap. | |
| 2693 | |
| 2694 For example, to make Vim identify all files in /etc/termcaps/ as termcap | |
| 2695 files, add the following: > | |
| 2696 | |
| 2697 :au BufNewFile,BufRead /etc/termcaps/* let b:ptcap_type = "term" | | |
| 2698 \ set filetype=ptcap | |
| 2699 | |
| 2700 If you notice highlighting errors while scrolling backwards, which | |
| 2701 are fixed when redrawing with CTRL-L, try setting the "ptcap_minlines" | |
| 2702 internal variable to a larger number: > | |
| 2703 | |
| 2704 :let ptcap_minlines = 50 | |
| 2705 | |
| 2706 (The default is 20 lines.) | |
| 2707 | |
| 2708 | |
| 501 | 2709 PROGRESS *progress.vim* *ft-progress-syntax* |
| 7 | 2710 |
| 2711 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
| 2712 doesn't work for you, or you don't edit cweb at all, use this in your | |
| 2713 startup vimrc: > | |
| 2714 :let filetype_w = "progress" | |
| 2715 The same happens for "*.i", which could be assembly, and "*.p", which could be | |
| 2716 Pascal. Use this if you don't use assembly and Pascal: > | |
| 2717 :let filetype_i = "progress" | |
| 2718 :let filetype_p = "progress" | |
| 2719 | |
| 2720 | |
| 501 | 2721 PYTHON *python.vim* *ft-python-syntax* |
| 7 | 2722 |
| 4186 | 2723 There are six options to control Python syntax highlighting. |
| 7 | 2724 |
| 2725 For highlighted numbers: > | |
| 4186 | 2726 :let python_no_number_highlight = 1 |
| 7 | 2727 |
| 2728 For highlighted builtin functions: > | |
| 4186 | 2729 :let python_no_builtin_highlight = 1 |
| 7 | 2730 |
| 2731 For highlighted standard exceptions: > | |
| 4186 | 2732 :let python_no_exception_highlight = 1 |
| 2733 | |
| 2734 For highlighted doctests and code inside: > | |
| 2735 :let python_no_doctest_highlight = 1 | |
| 2736 or > | |
| 2737 :let python_no_doctest_code_highlight = 1 | |
| 2738 (first option implies second one). | |
| 7 | 2739 |
| 2596 | 2740 For highlighted trailing whitespace and mix of spaces and tabs: > |
| 4186 | 2741 :let python_space_error_highlight = 1 |
| 7 | 2742 |
| 2743 If you want all possible Python highlighting (the same as setting the | |
| 4186 | 2744 preceding last option and unsetting all other ones): > |
| 7 | 2745 :let python_highlight_all = 1 |
| 2746 | |

2747 Note: Only existence of these options matter, not their value. You can replace |
| 4186 | 2748 1 above with anything. |
| 2749 | |
| 501 | 2750 QUAKE *quake.vim* *ft-quake-syntax* |
| 7 | 2751 |
| 19163 | 2752 The Quake syntax definition should work for most FPS (First Person Shooter) |
| 2753 based on one of the Quake engines. However, the command names vary a bit | |
| 2754 between the three games (Quake, Quake 2, and Quake 3 Arena) so the syntax | |
| 2755 definition checks for the existence of three global variables to allow users | |
| 2756 to specify what commands are legal in their files. The three variables can | |
| 2757 be set for the following effects: | |
| 7 | 2758 |
| 2759 set to highlight commands only available in Quake: > | |
| 2760 :let quake_is_quake1 = 1 | |
| 2761 | |
| 2762 set to highlight commands only available in Quake 2: > | |
| 2763 :let quake_is_quake2 = 1 | |
| 2764 | |
| 2765 set to highlight commands only available in Quake 3 Arena: > | |
| 2766 :let quake_is_quake3 = 1 | |
| 2767 | |
| 2768 Any combination of these three variables is legal, but might highlight more | |
| 2769 commands than are actually available to you by the game. | |
| 2770 | |
| 2771 | |
| 14637 | 2772 R *r.vim* *ft-r-syntax* |
| 2773 | |
| 2774 The parsing of R code for syntax highlight starts 40 lines backwards, but you | |
| 2775 can set a different value in your |vimrc|. Example: > | |
| 2776 let r_syntax_minlines = 60 | |
| 2777 | |
| 2778 You can also turn off syntax highlighting of ROxygen: > | |
| 2779 let r_syntax_hl_roxygen = 0 | |
| 2780 | |
| 2781 enable folding of code delimited by parentheses, square brackets and curly | |
| 2782 braces: > | |
| 2783 let r_syntax_folding = 1 | |
| 2784 | |
| 2785 and highlight as functions all keywords followed by an opening parenthesis: > | |
| 2786 let r_syntax_fun_pattern = 1 | |
| 2787 | |
| 2788 | |
| 2789 R MARKDOWN *rmd.vim* *ft-rmd-syntax* | |
| 2790 | |
| 2791 To disable syntax highlight of YAML header, add to your |vimrc|: > | |
| 2792 let rmd_syn_hl_yaml = 0 | |
| 2793 | |
| 2794 To disable syntax highlighting of citation keys: > | |
| 2795 let rmd_syn_hl_citations = 0 | |
| 2796 | |
| 2797 To highlight R code in knitr chunk headers: > | |
| 2798 let rmd_syn_hl_chunk = 1 | |
| 2799 | |
| 2800 By default, chunks of R code will be highlighted following the rules of R | |
| 2801 language. If you want proper syntax highlighting of chunks of other languages, | |
| 2802 you should add them to either `markdown_fenced_languages` or | |
| 2803 `rmd_fenced_languages`. For example to properly highlight both R and Python, | |
| 2804 you may add this to your |vimrc|: > | |
| 2805 let rmd_fenced_languages = ['r', 'python'] | |
| 2806 | |
| 2807 | |
| 2808 R RESTRUCTURED TEXT *rrst.vim* *ft-rrst-syntax* | |
| 2809 | |
| 2810 To highlight R code in knitr chunk headers, add to your |vimrc|: > | |
| 2811 let rrst_syn_hl_chunk = 1 | |
| 2812 | |
| 2813 | |
| 501 | 2814 READLINE *readline.vim* *ft-readline-syntax* |
| 7 | 2815 |
| 2816 The readline library is primarily used by the BASH shell, which adds quite a | |
| 237 | 2817 few commands and options to the ones already available. To highlight these |
| 7 | 2818 items as well you can add the following to your |vimrc| or just type it in the |
| 2819 command line before loading a file with the readline syntax: > | |
| 2820 let readline_has_bash = 1 | |
| 2821 | |
| 2822 This will add highlighting for the commands that BASH (version 2.05a and | |
| 2823 later, and part earlier) adds. | |
| 2824 | |
| 2825 | |
| 18928 | 2826 REGO *rego.vim* *ft-rego-syntax* |
| 2827 | |
| 2828 Rego is a query language developed by Styra. It is mostly used as a policy | |
| 2829 language for kubernetes, but can be applied to almost anything. Files with | |
| 2830 the following extensions are recognized as rego files: .rego. | |
| 2831 | |
| 2832 | |
| 3920 | 2833 RESTRUCTURED TEXT *rst.vim* *ft-rst-syntax* |
| 2834 | |
| 15334 | 2835 Syntax highlighting is enabled for code blocks within the document for a |
| 2836 select number of file types. See $VIMRUNTIME/syntax/rst.vim for the default | |
| 2837 syntax list. | |
| 2838 | |
| 2839 To set a user-defined list of code block syntax highlighting: > | |
| 3920 | 2840 let rst_syntax_code_list = ['vim', 'lisp', ...] |
| 15334 | 2841 |
| 2842 To assign multiple code block types to a single syntax, define | |
| 2843 `rst_syntax_code_list` as a mapping: > | |
| 2844 let rst_syntax_code_list = { | |
| 18719 | 2845 \ 'cpp': ['cpp', 'c++'], |
| 2846 \ 'bash': ['bash', 'sh'], | |
| 15334 | 2847 ... |
| 18719 | 2848 \ } |
| 15334 | 2849 |
| 2850 To use color highlighting for emphasis text: > | |
| 2851 let rst_use_emphasis_colors = 1 | |
| 2852 | |
| 2853 To enable folding of sections: > | |
| 2854 let rst_fold_enabled = 1 | |
| 2855 | |
| 2856 Note that folding can cause performance issues on some platforms. | |
| 2857 | |
| 3920 | 2858 |
| 501 | 2859 REXX *rexx.vim* *ft-rexx-syntax* |
| 7 | 2860 |
| 2861 If you notice highlighting errors while scrolling backwards, which are fixed | |
| 2862 when redrawing with CTRL-L, try setting the "rexx_minlines" internal variable | |
| 2863 to a larger number: > | |
| 2864 :let rexx_minlines = 50 | |
| 2865 This will make the syntax synchronization start 50 lines before the first | |
| 2866 displayed line. The default value is 10. The disadvantage of using a larger | |
| 2867 number is that redrawing can become slow. | |
| 2868 | |
| 2965 | 2869 Vim tries to guess what type a ".r" file is. If it can't be detected (from |
| 2870 comment lines), the default is "r". To make the default rexx add this line to | |
| 2871 your .vimrc: *g:filetype_r* | |
| 2872 > | |
| 2873 :let g:filetype_r = "r" | |

2946 Ruby: Reducing expensive operations ~ |
| 7 | 2947 |
| 2948 By default, the "end" keyword is colorized according to the opening statement | |
| 572 | 2949 of the block it closes. While useful, this feature can be expensive; if you |
| 7 | 2950 experience slow redrawing (or you are on a terminal with poor color support) |
| 2951 you may want to turn it off by defining the "ruby_no_expensive" variable: > | |
| 572 | 2952 |
| 7 | 2953 :let ruby_no_expensive = 1 |
| 1224 | 2954 < |
| 7 | 2955 In this case the same color will be used for all control keywords. |

| 7 | 2959 If you do want this feature enabled, but notice highlighting errors while |
| 2960 scrolling backwards, which are fixed when redrawing with CTRL-L, try setting | |

| 572 | 2962 |
| 7 | 2963 :let ruby_minlines = 100 |
| 1224 | 2964 < |
| 7 | 2965 Ideally, this value should be a number of lines large enough to embrace your |
| 2966 largest class or module. | |

| 501 | 2977 SCHEME *scheme.vim* *ft-scheme-syntax* |
| 17 | 2978 |
| 13231 | 2979 By default only R7RS keywords are highlighted and properly indented. |
| 2980 | |
| 2981 scheme.vim also supports extensions of the CHICKEN Scheme->C compiler. | |
| 2982 Define b:is_chicken or g:is_chicken, if you need them. | |
| 17 | 2983 |
| 2984 | |
| 501 | 2985 SDL *sdl.vim* *ft-sdl-syntax* |
| 7 | 2986 |
| 2987 The SDL highlighting probably misses a few keywords, but SDL has so many | |
| 2988 of them it's almost impossibly to cope. | |
| 2989 | |
| 2990 The new standard, SDL-2000, specifies that all identifiers are | |
| 2991 case-sensitive (which was not so before), and that all keywords can be | |
| 237 | 2992 used either completely lowercase or completely uppercase. To have the |
| 7 | 2993 highlighting reflect this, you can set the following variable: > |
| 2994 :let sdl_2000=1 | |
| 2995 | |
| 237 | 2996 This also sets many new keywords. If you want to disable the old |
| 7 | 2997 keywords, which is probably a good idea, use: > |
| 2998 :let SDL_no_96=1 | |
| 2999 | |
| 3000 | |
| 3001 The indentation is probably also incomplete, but right now I am very | |
| 3002 satisfied with it for my own projects. | |
| 3003 | |
| 3004 | |
| 501 | 3005 SED *sed.vim* *ft-sed-syntax* |
| 7 | 3006 |
| 3007 To make tabs stand out from regular blanks (accomplished by using Todo | |
| 3008 highlighting on the tabs), define "highlight_sedtabs" by putting > | |
| 3009 | |
| 3010 :let highlight_sedtabs = 1 | |
| 3011 | |
| 3012 in the vimrc file. (This special highlighting only applies for tabs | |
| 3013 inside search patterns, replacement texts, addresses or text included | |
| 3014 by an Append/Change/Insert command.) If you enable this option, it is | |
| 3015 also a good idea to set the tab width to one character; by doing that, | |
| 3016 you can easily count the number of tabs in a string. | |
| 3017 | |
| 3018 Bugs: | |
| 3019 | |
| 3020 The transform command (y) is treated exactly like the substitute | |
| 3021 command. This means that, as far as this syntax file is concerned, | |
| 3022 transform accepts the same flags as substitute, which is wrong. | |
| 3023 (Transform accepts no flags.) I tolerate this bug because the | |
| 3024 involved commands need very complex treatment (95 patterns, one for | |
| 3025 each plausible pattern delimiter). | |
| 3026 | |
| 3027 | |
| 501 | 3028 SGML *sgml.vim* *ft-sgml-syntax* |
| 7 | 3029 |
| 3030 The coloring scheme for tags in the SGML file works as follows. | |
| 3031 | |
| 3032 The <> of opening tags are colored differently than the </> of a closing tag. | |
| 3033 This is on purpose! For opening tags the 'Function' color is used, while for | |
| 3034 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
| 3035 defined for you) | |
| 3036 | |
| 3037 Known tag names are colored the same way as statements in C. Unknown tag | |
| 3038 names are not colored which makes it easy to spot errors. | |
| 3039 | |
| 237 | 3040 Note that the same is true for argument (or attribute) names. Known attribute |
| 7 | 3041 names are colored differently than unknown ones. |
| 3042 | |
| 237 | 3043 Some SGML tags are used to change the rendering of text. The following tags |
| 7 | 3044 are recognized by the sgml.vim syntax coloring file and change the way normal |
| 3045 text is shown: <varname> <emphasis> <command> <function> <literal> | |
| 3046 <replaceable> <ulink> and <link>. | |
| 3047 | |
| 3048 If you want to change how such text is rendered, you must redefine the | |
| 3049 following syntax groups: | |
| 3050 | |
| 3051 - sgmlBold | |
| 3052 - sgmlBoldItalic | |
| 3053 - sgmlUnderline | |
| 3054 - sgmlItalic | |
| 3055 - sgmlLink for links | |
| 3056 | |
| 3057 To make this redefinition work you must redefine them all and define the | |
| 3058 following variable in your vimrc (this is due to the order in which the files | |
| 3059 are read during initialization) > | |
| 3060 let sgml_my_rendering=1 | |
| 3061 | |
| 3062 You can also disable this rendering by adding the following line to your | |
| 3063 vimrc file: > | |
| 3064 let sgml_no_rendering=1 | |
| 3065 | |

3073 shells such as bash, dash, posix, and the Korn shells. |
| 7 | 3074 |
| 3075 Vim attempts to determine which shell type is in use by specifying that | |
| 14421 | 3076 various filenames are of specific types, e.g.: > |
| 7 | 3077 |
| 3078 ksh : .kshrc* *.ksh | |
| 3079 bash: .bashrc* bashrc bash.bashrc .bash_profile* *.bash | |
| 3080 < | |
| 14421 | 3081 See $VIMRUNTIME/filetype.vim for the full list of patterns. If none of these |
| 3082 cases pertain, then the first line of the file is examined (ex. looking for | |
| 3083 /bin/sh /bin/ksh /bin/bash). If the first line specifies a shelltype, then | |
| 3084 that shelltype is used. However some files (ex. .profile) are known to be | |
| 3085 shell files but the type is not apparent. Furthermore, on many systems sh is | |
| 3086 symbolically linked to "bash" (Linux, Windows+cygwin) or "ksh" (Posix). | |

3115 then various syntax items (ie. HereDocuments and function bodies) become |
| 1624 | 3116 syntax-foldable (see |:syn-fold|). You also may add these together |
| 3117 to get multiple types of folding: > | |
| 3118 | |
| 3119 let g:sh_fold_enabled= 3 (enables function and heredoc folding) | |
| 3120 | |
| 3121 If you notice highlighting errors while scrolling backwards which are fixed | |
| 3122 when one redraws with CTRL-L, try setting the "sh_minlines" internal variable | |
| 7 | 3123 to a larger number. Example: > |
| 3124 | |
| 3125 let sh_minlines = 500 | |
| 3126 | |
| 3127 This will make syntax synchronization start 500 lines before the first | |
| 3128 displayed line. The default value is 200. The disadvantage of using a larger | |
| 3129 number is that redrawing can become slow. | |
| 3130 | |
| 3131 If you don't have much to synchronize on, displaying can be very slow. To | |
| 3132 reduce this, the "sh_maxlines" internal variable can be set. Example: > | |
| 3133 | |
| 3134 let sh_maxlines = 100 | |
| 3135 < | |
| 3136 The default is to use the twice sh_minlines. Set it to a smaller number to | |
| 3137 speed up displaying. The disadvantage is that highlight errors may appear. | |

| 3209 While there is an ANSI standard for SQL, most database engines add their own | |

| 3212 | |
| 3213 Vim currently has SQL support for a variety of different vendors via syntax | |
| 3214 scripts. You can change Vim's default from Oracle to any of the current SQL | |

3312 Tex: Run-on Comments or MathZones ~ |

| 3315 highlighting supports three primary zones/regions: normal, texZone, and | |
| 3316 texMathZone. Although considerable effort has been made to have these zones | |
| 3317 terminate properly, zones delineated by $..$ and $$..$$ cannot be synchronized | |
| 3318 as there's no difference between start and end patterns. Consequently, a | |
| 7 | 3319 special "TeX comment" has been provided > |
| 3320 %stopzone | |
| 3321 which will forcibly terminate the highlighting of either a texZone or a | |
| 3322 texMathZone. | |

| 3339 Finally, if syntax highlighting is still too slow, you may set > | |
| 3340 | |
| 3341 :let g:tex_fast= "" | |
| 3342 | |
| 3343 in your .vimrc. Used this way, the g:tex_fast variable causes the syntax | |
| 3344 highlighting script to avoid defining any regions and associated | |
| 3345 synchronization. The result will be much faster syntax highlighting; the | |
| 3346 price: you will no longer have as much highlighting or any syntax-based | |
| 3347 folding, and you will be missing syntax-based error checking. | |
| 3348 | |
| 3349 You may decide that some syntax is acceptable; you may use the following table | |
| 3350 selectively to enable just some syntax highlighting: > | |
| 3351 | |
| 3352 b : allow bold and italic syntax | |
| 3353 c : allow texComment syntax | |
| 3354 m : allow texMatcher syntax (ie. {...} and [...]) | |
| 3355 M : allow texMath syntax | |
| 3356 p : allow parts, chapter, section, etc syntax | |
| 3357 r : allow texRefZone syntax (nocite, bibliography, label, pageref, eqref) | |
| 3358 s : allow superscript/subscript regions | |
| 3359 S : allow texStyle syntax | |
| 3360 v : allow verbatim syntax | |
| 3361 V : allow texNewEnv and texNewCmd syntax | |
| 3362 < | |

3368 Tex: Want To Highlight More Commands? ~ |
| 1125 | 3369 |
| 3370 LaTeX is a programmable language, and so there are thousands of packages full | |
| 3371 of specialized LaTeX commands, syntax, and fonts. If you're using such a | |
| 3372 package you'll often wish that the distributed syntax/tex.vim would support | |
| 3373 it. However, clearly this is impractical. So please consider using the | |
| 3374 techniques in |mysyntaxfile-add| to extend or modify the highlighting provided | |
| 3237 | 3375 by syntax/tex.vim. Please consider uploading any extensions that you write, |
| 3376 which typically would go in $HOME/after/syntax/tex/[pkgname].vim, to | |
| 3377 http://vim.sf.net/. | |

| 3398 If you want to include a new math group in your LaTeX, the following | |
| 3399 code shows you an example as to how you might do so: > | |
| 477 | 3400 call TexNewMathZone(sfx,mathzone,starform) |
| 3401 You'll want to provide the new math group with a unique suffix | |
| 3402 (currently, A-L and V-Z are taken by <syntax/tex.vim> itself). | |
| 3403 As an example, consider how eqnarray is set up by <syntax/tex.vim>: > | |
| 3404 call TexNewMathZone("D","eqnarray",1) | |
| 3405 You'll need to change "mathzone" to the name of your new math group, | |
| 3406 and then to the call to it in .vim/after/syntax/tex.vim. | |
| 3407 The "starform" variable, if true, implies that your new math group | |

| 3414 commands available. However, since the *.tex file doesn't have one of the | |

3425 Tex: Taking Advantage of Conceal Mode~ |
| 2417 | 3426 |
| 2426 | 3427 If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a |
| 3428 number of character sequences can be translated into appropriate utf-8 glyphs, | |
| 3429 including various accented characters, Greek characters in MathZones, and | |
| 3430 superscripts and subscripts in MathZones. Not all characters can be made into | |
| 3431 superscripts or subscripts; the constraint is due to what utf-8 supports. | |
| 3432 In fact, only a few characters are supported as subscripts. | |
| 3433 | |
| 3434 One way to use this is to have vertically split windows (see |CTRL-W_v|); one | |
| 3435 with |'conceallevel'| at 0 and the other at 2; and both using |'scrollbind'|. | |

| 3459 syntax highlighting script handles this with the following logic: | |
| 3460 | |
| 3461 * If g:tex_stylish exists and is 1 | |
| 3462 then the file will be treated as a "sty" file, so the "_" | |
| 3463 will be allowed as part of keywords | |

| 3466 then the file will be treated as a "sty" file, so the "_" | |

| 3470 * If g:tex_isk exists, then it will be used for the local 'iskeyword' | |

| 3474 Tex: Fine Subscript and Superscript Control~ | |
| 3475 | |
| 3476 See |tex-conceal| for how to enable concealed character replacement. | |
| 3477 | |
| 3478 See |g:tex_conceal| for selectively concealing accents, bold/italic, | |
| 3479 math, Greek, and superscripts/subscripts. | |
| 3480 | |
| 3481 One may exert fine control over which superscripts and subscripts one | |
| 3482 wants syntax-based concealment for (see |:syn-cchar|). Since not all | |
| 3483 fonts support all characters, one may override the | |
| 3484 concealed-replacement lists; by default these lists are given by: > | |
| 3485 | |
| 3486 let g:tex_superscripts= "[0-9a-zA-W.,:;+-<>/()=]" | |
| 3487 let g:tex_subscripts= "[0-9aehijklmnoprstuvx,+-/().]" | |
| 3488 < | |
| 3489 For example, I use Luxi Mono Bold; it doesn't support subscript | |
| 3490 characters for "hklmnpst", so I put > | |
| 3491 let g:tex_subscripts= "[0-9aeijoruvx,+-/().]" | |
| 3492 < in ~/.vim/ftplugin/tex/tex.vim in order to avoid having inscrutable | |
| 3493 utf-8 glyphs appear. | |
| 3494 | |
| 23164 | 3495 *tex-matchcheck* *g:tex_matchcheck* |
| 3496 Tex: Match Check Control~ | |
| 3497 | |
| 3498 Sometimes one actually wants mismatched parentheses, square braces, | |
| 24911 | 3499 and or curly braces; for example, \text{(1,10]} is a range from but |
| 3500 not including 1 to and including 10. This wish, of course, conflicts | |
| 23164 | 3501 with the desire to provide delimiter mismatch detection. To |
| 3502 accommodate these conflicting goals, syntax/tex.vim provides > | |
| 3503 g:tex_matchcheck = '[({[]' | |
| 3504 < which is shown along with its default setting. So, if one doesn't | |
| 3505 want [] and () to be checked for mismatches, try using > | |
| 3506 let g:tex_matchcheck= '[{}]' | |
| 3507 < If you don't want matching to occur inside bold and italicized | |
| 3508 regions, > | |
| 3509 let g:tex_excludematcher= 1 | |
| 3510 < will prevent the texMatcher group from being included in those regions. | |

3566 is a difficult language to highlight correctly. A way to suppress error |
| 1624 | 3567 highlighting is to put the following line in your |vimrc|: > |
| 3568 | |

| 3570 < | |

| 501 | 3573 XF86CONFIG *xf86conf.vim* *ft-xf86conf-syntax* |
| 7 | 3574 |
| 3575 The syntax of XF86Config file differs in XFree86 v3.x and v4.x. Both | |
| 3576 variants are supported. Automatic detection is used, but is far from perfect. | |
| 3577 You may need to specify the version manually. Set the variable | |
| 3578 xf86conf_xfree86_version to 3 or 4 according to your XFree86 version in | |
| 3579 your .vimrc. Example: > | |
| 3580 :let xf86conf_xfree86_version=3 | |
| 3581 When using a mix of versions, set the b:xf86conf_xfree86_version variable. | |
| 3582 | |
| 3583 Note that spaces and underscores in option names are not supported. Use | |
| 3584 "SyncOnGreen" instead of "__s yn con gr_e_e_n" if you want the option name | |
| 3585 highlighted. | |

| 3587 | |

| 3595 *xml-folding* | |
| 3596 The xml syntax file provides syntax |folding| (see |:syn-fold|) between | |
| 237 | 3597 start and end tags. This can be turned on by > |
| 7 | 3598 |
| 3599 :let g:xml_syntax_folding = 1 | |

3602 Note: Syntax folding might slow down syntax highlighting significantly, |
| 7 | 3603 especially for large files. |
| 3604 | |
| 3605 | |
| 501 | 3606 X Pixmaps (XPM) *xpm.vim* *ft-xpm-syntax* |
| 7 | 3607 |
| 3608 xpm.vim creates its syntax items dynamically based upon the contents of the | |
| 3609 XPM file. Thus if you make changes e.g. in the color specification strings, | |
| 3610 you have to source it again e.g. with ":set syn=xpm". | |
| 3611 | |
| 3612 To copy a pixel with one of the colors, yank a "pixel" with "yl" and insert it | |
| 3613 somewhere else with "P". | |
| 3614 | |
| 3615 Do you want to draw with the mouse? Try the following: > | |
| 3616 :function! GetPixel() | |
| 823 | 3617 : let c = getline(".")[col(".") - 1] |
| 7 | 3618 : echo c |
| 27903 | 3619 : exe "noremap <LeftMouse> <LeftMouse>r" .. c |
| 3620 : exe "noremap <LeftDrag> <LeftMouse>r" .. c | |
| 7 | 3621 :endfunction |
| 3622 :noremap <RightMouse> <LeftMouse>:call GetPixel()<CR> | |
| 3623 :set guicursor=n:hor20 " to see the color beneath the cursor | |
| 3624 This turns the right button into a pipette and the left button into a pen. | |
| 3625 It will work with XPM files that have one character per pixel only and you | |
| 3626 must not click outside of the pixel strings, but feel free to improve it. | |
| 3627 | |
| 3628 It will look much better with a font in a quadratic cell size, e.g. for X: > | |
| 3629 :set guifont=-*-clean-medium-r-*-*-8-*-*-*-*-80-* | |
| 3630 | |
| 6741 | 3631 |
| 3632 YAML *yaml.vim* *ft-yaml-syntax* | |
| 3633 | |
| 3634 *g:yaml_schema* *b:yaml_schema* | |
| 18831 | 3635 A YAML schema is a combination of a set of tags and a mechanism for resolving |
| 3636 non-specific tags. For user this means that YAML parser may, depending on | |
| 3637 plain scalar contents, treat plain scalar (which can actually be only string | |
| 3638 and nothing else) as a value of the other type: null, boolean, floating-point, | |
| 3639 integer. `g:yaml_schema` option determines according to which schema values | |
| 6741 | 3640 will be highlighted specially. Supported schemas are |
| 3641 | |
| 3642 Schema Description ~ | |
| 3643 failsafe No additional highlighting. | |
| 3644 json Supports JSON-style numbers, booleans and null. | |
| 3645 core Supports more number, boolean and null styles. | |
| 18831 | 3646 pyyaml In addition to core schema supports highlighting timestamps, |
| 3647 but there are some differences in what is recognized as | |
| 3648 numbers and many additional boolean values not present in core | |
| 6741 | 3649 schema. |
| 3650 | |
| 3651 Default schema is `core`. | |
| 3652 | |
| 18831 | 3653 Note that schemas are not actually limited to plain scalars, but this is the |
| 3654 only difference between schemas defined in YAML specification and the only | |
| 6741 | 3655 difference defined in the syntax file. |

| 7 | 3664 ============================================================================== |
| 15194 | 3665 6. Defining a syntax *:syn-define* *E410* |
| 7 | 3666 |
| 3667 Vim understands three types of syntax items: | |
| 3668 | |
| 419 | 3669 1. Keyword |
| 7 | 3670 It can only contain keyword characters, according to the 'iskeyword' |
| 3671 option. It cannot contain other syntax items. It will only match with a | |
| 3672 complete word (there are no keyword characters before or after the match). | |
| 3673 The keyword "if" would match in "if(a=b)", but not in "ifdef x", because | |
| 3674 "(" is not a keyword character and "d" is. | |
| 3675 | |
| 419 | 3676 2. Match |
| 7 | 3677 This is a match with a single regexp pattern. |
| 3678 | |
| 419 | 3679 3. Region |
| 7 | 3680 This starts at a match of the "start" regexp pattern and ends with a match |
| 3681 with the "end" regexp pattern. Any other text can appear in between. A | |
| 3682 "skip" regexp pattern can be used to avoid matching the "end" pattern. | |
| 3683 | |
| 3684 Several syntax ITEMs can be put into one syntax GROUP. For a syntax group | |
| 3685 you can give highlighting attributes. For example, you could have an item | |
| 3686 to define a "/* .. */" comment and another one that defines a "// .." comment, | |
| 3687 and put them both in the "Comment" group. You can then specify that a | |
| 3688 "Comment" will be in bold font and have a blue color. You are free to make | |
| 3689 one highlight group for one syntax item, or put all items into one group. | |
| 3690 This depends on how you want to specify your highlighting attributes. Putting | |
| 3691 each item in its own group results in having to specify the highlighting | |
| 3692 for a lot of groups. | |
| 3693 | |
| 3694 Note that a syntax group and a highlight group are similar. For a highlight | |
| 3695 group you will have given highlight attributes. These attributes will be used | |
| 3696 for the syntax group with the same name. | |
| 3697 | |
| 3698 In case more than one item matches at the same position, the one that was | |
| 3699 defined LAST wins. Thus you can override previously defined syntax items by | |
| 3700 using an item that matches the same text. But a keyword always goes before a | |
| 3701 match or region. And a keyword with matching case always goes before a | |
| 3702 keyword with ignoring case. | |
| 3703 | |
| 3704 | |
| 3705 PRIORITY *:syn-priority* | |
| 3706 | |
| 3707 When several syntax items may match, these rules are used: | |
| 3708 | |
| 3709 1. When multiple Match or Region items start in the same position, the item | |
| 3710 defined last has priority. | |
| 3711 2. A Keyword has priority over Match and Region items. | |
| 3712 3. An item that starts in an earlier position has priority over items that | |
| 3713 start in later positions. | |
| 3714 | |
| 3715 | |
| 3716 DEFINING CASE *:syn-case* *E390* | |
| 3717 | |
| 419 | 3718 :sy[ntax] case [match | ignore] |
| 7 | 3719 This defines if the following ":syntax" commands will work with |
| 3720 matching case, when using "match", or with ignoring case, when using | |
| 3721 "ignore". Note that any items before this are not affected, and all | |
| 3722 items until the next ":syntax case" command are affected. | |
| 3723 | |
| 10734 | 3724 :sy[ntax] case |
| 27623 | 3725 Show either "syntax case match" or "syntax case ignore". |

3818 < *E789* *E890* |
| 7 | 3819 When you have a keyword with an optional tail, like Ex commands in |
| 3820 Vim, you can put the optional characters inside [], to define all the | |
| 3821 variations at once: > | |
| 3822 :syntax keyword vimCommand ab[breviate] n[ext] | |
| 3823 < | |
| 3824 Don't forget that a keyword can only be recognized if all the | |
| 3825 characters are included in the 'iskeyword' option. If one character | |
| 3826 isn't, the keyword will never be recognized. | |
| 3827 Multi-byte characters can also be used. These do not have to be in | |
| 3828 'iskeyword'. | |

3829 See |:syn-iskeyword| for defining syntax specific iskeyword settings. |
| 7 | 3830 |
| 3831 A keyword always has higher priority than a match or region, the | |
| 3832 keyword is used if more than one item matches. Keywords do not nest | |
| 3833 and a keyword can't contain anything else. | |
| 3834 | |
| 3835 Note that when you have a keyword that is the same as an option (even | |
| 3836 one that isn't allowed here), you can not use it. Use a match | |
| 3837 instead. | |
| 3838 | |
| 3839 The maximum length of a keyword is 80 characters. | |
| 3840 | |
| 3841 The same keyword can be defined multiple times, when its containment | |
| 3842 differs. For example, you can define the keyword once not contained | |
| 3843 and use one highlight group, and once contained, and use a different | |
| 237 | 3844 highlight group. Example: > |
| 7 | 3845 :syn keyword vimCommand tag |
| 3846 :syn keyword vimSetting contained tag | |
| 3847 < When finding "tag" outside of any syntax item, the "vimCommand" | |
| 3848 highlight group is used. When finding "tag" in a syntax item that | |
| 3849 contains "vimSetting", the "vimSetting" group is used. | |

| 3925 start and end patterns. This means that you can omit the skip | |
| 3926 pattern, but you must give at least one start and one end pattern. It | |
| 3927 is allowed to have white space before and after the equal sign | |
| 3928 (although it mostly looks better without white space). | |
| 3929 | |
| 3930 When more than one start pattern is given, a match with one of these | |
| 3931 is sufficient. This means there is an OR relation between the start | |
| 3932 patterns. The last one that matches is used. The same is true for | |
| 3933 the end patterns. | |
| 3934 | |
| 3935 The search for the end pattern starts right after the start pattern. | |
| 3936 Offsets are not used for this. This implies that the match for the | |
| 3937 end pattern will never overlap with the start pattern. | |
| 3938 | |
| 3939 The skip and end pattern can match across line breaks, but since the | |
| 3940 search for the pattern can start in any line it often does not do what | |
| 3941 you want. The skip pattern doesn't avoid a match of an end pattern in | |
| 3942 the next line. Use single-line patterns to avoid trouble. | |
| 3943 | |
| 3944 Note: The decision to start a region is only based on a matching start | |
| 3945 pattern. There is no check for a matching end pattern. This does NOT | |
| 3946 work: > | |
| 3947 :syn region First start="(" end=":" | |
| 3948 :syn region Second start="(" end=";" | |
| 3949 < The Second always matches before the First (last defined pattern has | |
| 3950 higher priority). The Second region then continues until the next | |
| 3951 ';', no matter if there is a ':' before it. Using a match does work: > | |
| 3952 :syn match First "(\_.\{-}:" | |
| 3953 :syn match Second "(\_.\{-};" | |
| 3954 < This pattern matches any character or line break with "\_." and | |
| 3955 repeats that with "\{-}" (repeat as few as possible). | |
| 3956 | |
| 3957 *:syn-keepend* | |
| 3958 By default, a contained match can obscure a match for the end pattern. | |
| 3959 This is useful for nesting. For example, a region that starts with | |
| 3960 "{" and ends with "}", can contain another region. An encountered "}" | |
| 3961 will then end the contained region, but not the outer region: | |
| 3962 { starts outer "{}" region | |
| 3963 { starts contained "{}" region | |
| 3964 } ends contained "{}" region | |
| 3965 } ends outer "{} region | |
| 3966 If you don't want this, the "keepend" argument will make the matching | |
| 3967 of an end pattern of the outer region also end any contained item. | |
| 3968 This makes it impossible to nest the same region, but allows for | |
| 3969 contained items to highlight parts of the end pattern, without causing | |
| 3970 that to skip the match with the end pattern. Example: > | |
| 3971 :syn match vimComment +"[^"]\+$+ | |
| 3972 :syn region vimCommand start="set" end="$" contains=vimComment keepend | |
| 3973 < The "keepend" makes the vimCommand always end at the end of the line, | |
| 3974 even though the contained vimComment includes a match with the <EOL>. | |
| 3975 | |
| 3976 When "keepend" is not used, a match with an end pattern is retried | |
| 3977 after each contained match. When "keepend" is included, the first | |
| 3978 encountered match with an end pattern is used, truncating any | |
| 3979 contained matches. | |
| 3980 *:syn-extend* | |
| 3981 The "keepend" behavior can be changed by using the "extend" argument. | |
| 3982 When an item with "extend" is contained in an item that uses | |
| 3983 "keepend", the "keepend" is ignored and the containing region will be | |
| 3984 extended. | |
| 3985 This can be used to have some contained items extend a region while | |
| 3986 others don't. Example: > | |
| 3987 | |
| 3988 :syn region htmlRef start=+<a>+ end=+</a>+ keepend contains=htmlItem,htmlScript | |
| 3989 :syn match htmlItem +<[^>]*>+ contained | |
| 3990 :syn region htmlScript start=+<script+ end=+</script[^>]*>+ contained extend | |
| 3991 | |
| 3992 < Here the htmlItem item does not make the htmlRef item continue | |
| 3993 further, it is only used to highlight the <> items. The htmlScript | |
| 3994 item does extend the htmlRef item. | |
| 3995 | |
| 3996 Another example: > | |
| 3997 :syn region xmlFold start="<a>" end="</a>" fold transparent keepend extend | |
| 3998 < This defines a region with "keepend", so that its end cannot be | |
| 3999 changed by contained items, like when the "</a>" is matched to | |
| 4000 highlight it differently. But when the xmlFold region is nested (it | |
| 4001 includes itself), the "extend" applies, so that the "</a>" of a nested | |
| 4002 region only ends that region, and not the one it is contained in. | |
| 4003 | |
| 4004 *:syn-excludenl* | |
| 4005 When a pattern for a match or end pattern of a region includes a '$' | |
| 4006 to match the end-of-line, it will make a region item that it is | |
| 4007 contained in continue on the next line. For example, a match with | |
| 4008 "\\$" (backslash at the end of the line) can make a region continue | |
| 4009 that would normally stop at the end of the line. This is the default | |
| 4010 behavior. If this is not wanted, there are two ways to avoid it: | |
| 4011 1. Use "keepend" for the containing item. This will keep all | |
| 4012 contained matches from extending the match or region. It can be | |
| 4013 used when all contained items must not extend the containing item. | |
| 4014 2. Use "excludenl" in the contained item. This will keep that match | |
| 4015 from extending the containing match or region. It can be used if | |
| 4016 only some contained items must not extend the containing item. | |
| 4017 "excludenl" must be given before the pattern it applies to. | |
| 4018 | |
| 4019 *:syn-matchgroup* | |
| 4020 "matchgroup" can be used to highlight the start and/or end pattern | |
| 4021 differently than the body of the region. Example: > | |
| 4022 :syntax region String matchgroup=Quote start=+"+ skip=+\\"+ end=+"+ | |
| 4023 < This will highlight the quotes with the "Quote" group, and the text in | |
| 4024 between with the "String" group. | |
| 4025 The "matchgroup" is used for all start and end patterns that follow, | |
| 4026 until the next "matchgroup". Use "matchgroup=NONE" to go back to not | |
| 4027 using a matchgroup. | |
| 4028 | |
| 4029 In a start or end pattern that is highlighted with "matchgroup" the | |
| 4030 contained items of the region are not used. This can be used to avoid | |
| 4031 that a contained item matches in the start or end pattern match. When | |
| 4032 using "transparent", this does not apply to a start or end pattern | |
| 4033 match that is highlighted with "matchgroup". | |
| 4034 | |
| 4035 Here is an example, which highlights three levels of parentheses in | |
| 4036 different colors: > | |
| 4037 :sy region par1 matchgroup=par1 start=/(/ end=/)/ contains=par2 | |
| 4038 :sy region par2 matchgroup=par2 start=/(/ end=/)/ contains=par3 contained | |
| 4039 :sy region par3 matchgroup=par3 start=/(/ end=/)/ contains=par1 contained | |
| 4040 :hi par1 ctermfg=red guifg=red | |
| 4041 :hi par2 ctermfg=blue guifg=blue | |
| 4042 :hi par3 ctermfg=darkgreen guifg=darkgreen | |
| 2751 | 4043 < |
| 4044 *E849* | |
| 4045 The maximum number of syntax groups is 19999. | |

4098 See |hl-Conceal| for highlighting. |
| 7 | 4099 |
| 4100 contained *:syn-contained* | |
| 4101 | |
| 4102 When the "contained" argument is given, this item will not be recognized at | |
| 4103 the top level, but only when it is mentioned in the "contains" field of | |
| 4104 another match. Example: > | |
| 4105 :syntax keyword Todo TODO contained | |
| 4106 :syntax match Comment "//.*" contains=Todo | |
| 4107 | |
| 4108 | |
| 4109 display *:syn-display* | |
| 4110 | |
| 4111 If the "display" argument is given, this item will be skipped when the | |
| 4112 detected highlighting will not be displayed. This will speed up highlighting, | |
| 4113 by skipping this item when only finding the syntax state for the text that is | |
| 4114 to be displayed. | |
| 4115 | |
| 4116 Generally, you can use "display" for match and region items that meet these | |
| 4117 conditions: | |
| 4118 - The item does not continue past the end of a line. Example for C: A region | |
| 4119 for a "/*" comment can't contain "display", because it continues on the next | |
| 4120 line. | |
| 4121 - The item does not contain items that continue past the end of the line or | |
| 4122 make it continue on the next line. | |
| 4123 - The item does not change the size of any item it is contained in. Example | |
| 4124 for C: A match with "\\$" in a preprocessor match can't have "display", | |
| 4125 because it may make that preprocessor match shorter. | |
| 4126 - The item does not allow other items to match that didn't match otherwise, | |
| 4127 and that item may extend the match too far. Example for C: A match for a | |
| 4128 "//" comment can't use "display", because a "/*" inside that comment would | |
| 4129 match then and start a comment which extends past the end of the line. | |
| 4130 | |
| 4131 Examples, for the C language, where "display" can be used: | |
| 4132 - match with a number | |
| 4133 - match with a label | |
| 4134 | |
| 4135 | |
| 4136 transparent *:syn-transparent* | |
| 4137 | |
| 4138 If the "transparent" argument is given, this item will not be highlighted | |
| 4139 itself, but will take the highlighting of the item it is contained in. This | |
| 4140 is useful for syntax items that don't need any highlighting but are used | |
| 4141 only to skip over a part of the text. | |
| 4142 | |
| 4143 The "contains=" argument is also inherited from the item it is contained in, | |
| 4144 unless a "contains" argument is given for the transparent item itself. To | |
| 4145 avoid that unwanted items are contained, use "contains=NONE". Example, which | |
| 4146 highlights words in strings, but makes an exception for "vim": > | |
| 4147 :syn match myString /'[^']*'/ contains=myWord,myVim | |
| 4148 :syn match myWord /\<[a-z]*\>/ contained | |
| 4149 :syn match myVim /\<vim\>/ transparent contained contains=NONE | |
| 4150 :hi link myString String | |
| 4151 :hi link myWord Comment | |
| 4152 Since the "myVim" match comes after "myWord" it is the preferred match (last | |
| 4153 match in the same position overrules an earlier one). The "transparent" | |
| 4154 argument makes the "myVim" match use the same highlighting as "myString". But | |
| 4155 it does not contain anything. If the "contains=NONE" argument would be left | |
| 4156 out, then "myVim" would use the contains argument from myString and allow | |
| 24911 | 4157 "myWord" to be contained, which will be highlighted as a Comment. This |
| 7 | 4158 happens because a contained match doesn't match inside itself in the same |
| 4159 position, thus the "myVim" match doesn't overrule the "myWord" match here. | |
| 4160 | |
| 4161 When you look at the colored text, it is like looking at layers of contained | |
| 4162 items. The contained item is on top of the item it is contained in, thus you | |
| 4163 see the contained item. When a contained item is transparent, you can look | |
| 4164 through, thus you see the item it is contained in. In a picture: | |
| 4165 | |
| 4166 look from here | |
| 4167 | |
| 4168 | | | | | | | |
| 4169 V V V V V V | |
| 4170 | |
| 4171 xxxx yyy more contained items | |
| 4172 .................... contained item (transparent) | |
| 4173 ============================= first item | |
| 4174 | |
| 4175 The 'x', 'y' and '=' represent a highlighted syntax item. The '.' represent a | |
| 4176 transparent group. | |
| 4177 | |
| 4178 What you see is: | |
| 4179 | |
| 4180 =======xxxx=======yyy======== | |
| 4181 | |
| 4182 Thus you look through the transparent "....". | |
| 4183 | |
| 4184 | |
| 4185 oneline *:syn-oneline* | |
| 4186 | |
| 4187 The "oneline" argument indicates that the region does not cross a line | |
| 4188 boundary. It must match completely in the current line. However, when the | |
| 4189 region has a contained item that does cross a line boundary, it continues on | |
| 4190 the next line anyway. A contained item can be used to recognize a line | |
| 4191 continuation pattern. But the "end" pattern must still match in the first | |
| 4192 line, otherwise the region doesn't even start. | |
| 4193 | |
| 4194 When the start pattern includes a "\n" to match an end-of-line, the end | |
| 4195 pattern must be found in the same line as where the start pattern ends. The | |
| 4196 end pattern may also include an end-of-line. Thus the "oneline" argument | |
| 4197 means that the end of the start pattern and the start of the end pattern must | |
| 4198 be within one line. This can't be changed by a skip pattern that matches a | |
| 4199 line break. | |
| 4200 | |
| 4201 | |
| 4202 fold *:syn-fold* | |
| 4203 | |
| 1624 | 4204 The "fold" argument makes the fold level increase by one for this item. |
| 7 | 4205 Example: > |
| 4206 :syn region myFold start="{" end="}" transparent fold | |
| 4207 :syn sync fromstart | |
| 4208 :set foldmethod=syntax | |
| 4209 This will make each {} block form one fold. | |
| 4210 | |
| 4211 The fold will start on the line where the item starts, and end where the item | |
| 4212 ends. If the start and end are within the same line, there is no fold. | |
| 4213 The 'foldnestmax' option limits the nesting of syntax folds. | |

| 4219 *:syn-contains* *E405* *E406* *E407* *E408* *E409* | |
| 6259 | 4220 contains={group-name},.. |
| 7 | 4221 |
| 4222 The "contains" argument is followed by a list of syntax group names. These | |
| 4223 groups will be allowed to begin inside the item (they may extend past the | |
| 4224 containing group's end). This allows for recursive nesting of matches and | |
| 4225 regions. If there is no "contains" argument, no groups will be contained in | |
| 4226 this item. The group names do not need to be defined before they can be used | |
| 4227 here. | |
| 4228 | |
| 4229 contains=ALL | |
| 4230 If the only item in the contains list is "ALL", then all | |
| 4231 groups will be accepted inside the item. | |
| 4232 | |
| 4233 contains=ALLBUT,{group-name},.. | |
| 4234 If the first item in the contains list is "ALLBUT", then all | |
| 4235 groups will be accepted inside the item, except the ones that | |
| 4236 are listed. Example: > | |
| 4237 :syntax region Block start="{" end="}" ... contains=ALLBUT,Function | |
| 4238 | |
| 4239 contains=TOP | |
| 4240 If the first item in the contains list is "TOP", then all | |
| 4241 groups will be accepted that don't have the "contained" | |
| 4242 argument. | |
| 4243 contains=TOP,{group-name},.. | |
| 4244 Like "TOP", but excluding the groups that are listed. | |
| 4245 | |
| 4246 contains=CONTAINED | |
| 4247 If the first item in the contains list is "CONTAINED", then | |
| 4248 all groups will be accepted that have the "contained" | |
| 4249 argument. | |
| 4250 contains=CONTAINED,{group-name},.. | |
| 4251 Like "CONTAINED", but excluding the groups that are | |
| 4252 listed. | |
| 4253 | |
| 4254 | |
| 4255 The {group-name} in the "contains" list can be a pattern. All group names | |
| 4256 that match the pattern will be included (or excluded, if "ALLBUT" is used). | |
| 4257 The pattern cannot contain white space or a ','. Example: > | |
| 4258 ... contains=Comment.*,Keyw[0-3] | |
| 4259 The matching will be done at moment the syntax command is executed. Groups | |
| 4260 that are defined later will not be matched. Also, if the current syntax | |
| 4261 command defines a new group, it is not matched. Be careful: When putting | |
| 4262 syntax commands in a file you can't rely on groups NOT being defined, because | |
| 4263 the file may have been sourced before, and ":syn clear" doesn't remove the | |
| 4264 group names. | |
| 4265 | |
| 4266 The contained groups will also match in the start and end patterns of a | |
| 4267 region. If this is not wanted, the "matchgroup" argument can be used | |
| 4268 |:syn-matchgroup|. The "ms=" and "me=" offsets can be used to change the | |
| 4269 region where contained items do match. Note that this may also limit the | |
| 4270 area that is highlighted | |
| 4271 | |
| 4272 | |
| 6259 | 4273 containedin={group-name}... *:syn-containedin* |
| 7 | 4274 |
| 4275 The "containedin" argument is followed by a list of syntax group names. The | |
| 4276 item will be allowed to begin inside these groups. This works as if the | |
| 4277 containing item has a "contains=" argument that includes this item. | |
| 4278 | |
| 6259 | 4279 The {group-name}... can be used just like for "contains", as explained above. |
| 7 | 4280 |
| 4281 This is useful when adding a syntax item afterwards. An item can be told to | |
| 4282 be included inside an already existing item, without changing the definition | |
| 4283 of that item. For example, to highlight a word in a C comment after loading | |
| 4284 the C syntax: > | |
| 4285 :syn keyword myword HELP containedin=cComment contained | |
| 4286 Note that "contained" is also used, to avoid that the item matches at the top | |
| 4287 level. | |
| 4288 | |
| 4289 Matches for "containedin" are added to the other places where the item can | |
| 4290 appear. A "contains" argument may also be added as usual. Don't forget that | |
| 4291 keywords never contain another item, thus adding them to "containedin" won't | |
| 4292 work. | |
| 4293 | |
| 4294 | |
| 6259 | 4295 nextgroup={group-name},.. *:syn-nextgroup* |
| 7 | 4296 |
| 4297 The "nextgroup" argument is followed by a list of syntax group names, | |
| 4298 separated by commas (just like with "contains", so you can also use patterns). | |
| 4299 | |
| 4300 If the "nextgroup" argument is given, the mentioned syntax groups will be | |
| 4301 tried for a match, after the match or region ends. If none of the groups have | |
| 4302 a match, highlighting continues normally. If there is a match, this group | |
| 4303 will be used, even when it is not mentioned in the "contains" field of the | |
| 4304 current group. This is like giving the mentioned group priority over all | |
| 4305 other groups. Example: > | |
| 4306 :syntax match ccFoobar "Foo.\{-}Bar" contains=ccFoo | |
| 4307 :syntax match ccFoo "Foo" contained nextgroup=ccFiller | |
| 4308 :syntax region ccFiller start="." matchgroup=ccBar end="Bar" contained | |
| 4309 | |
| 4310 This will highlight "Foo" and "Bar" differently, and only when there is a | |
| 4311 "Bar" after "Foo". In the text line below, "f" shows where ccFoo is used for | |
| 4312 highlighting, and "bbb" where ccBar is used. > | |
| 4313 | |
| 4314 Foo asdfasd Bar asdf Foo asdf Bar asdf | |
| 4315 fff bbb fff bbb | |
| 4316 | |
| 4317 Note the use of ".\{-}" to skip as little as possible until the next Bar. | |
| 4318 when ".*" would be used, the "asdf" in between "Bar" and "Foo" would be | |
| 4319 highlighted according to the "ccFoobar" group, because the ccFooBar match | |
| 4320 would include the first "Foo" and the last "Bar" in the line (see |pattern|). | |
| 4321 | |
| 4322 | |
| 4323 skipwhite *:syn-skipwhite* | |
| 4324 skipnl *:syn-skipnl* | |
| 4325 skipempty *:syn-skipempty* | |
| 4326 | |
| 4327 These arguments are only used in combination with "nextgroup". They can be | |
| 4328 used to allow the next group to match after skipping some text: | |
| 1275 | 4329 skipwhite skip over space and tab characters |
| 7 | 4330 skipnl skip over the end of a line |
| 4331 skipempty skip over empty lines (implies a "skipnl") | |
| 4332 | |
| 4333 When "skipwhite" is present, the white space is only skipped if there is no | |
| 4334 next group that matches the white space. | |
| 4335 | |
| 4336 When "skipnl" is present, the match with nextgroup may be found in the next | |
| 4337 line. This only happens when the current item ends at the end of the current | |
| 4338 line! When "skipnl" is not present, the nextgroup will only be found after | |
| 4339 the current item in the same line. | |
| 4340 | |
| 4341 When skipping text while looking for a next group, the matches for other | |
| 4342 groups are ignored. Only when no next group matches, other items are tried | |
| 4343 for a match again. This means that matching a next group and skipping white | |
| 4344 space and <EOL>s has a higher priority than other items. | |
| 4345 | |
| 4346 Example: > | |
| 4347 :syn match ifstart "\<if.*" nextgroup=ifline skipwhite skipempty | |
| 4348 :syn match ifline "[^ \t].*" nextgroup=ifline skipwhite skipempty contained | |
| 4349 :syn match ifline "endif" contained | |
| 4350 Note that the "[^ \t].*" match matches all non-white text. Thus it would also | |
| 4351 match "endif". Therefore the "endif" match is put last, so that it takes | |
| 4352 precedence. | |
| 4353 Note that this example doesn't work for nested "if"s. You need to add | |
| 4354 "contains" arguments to make that work (omitted for simplicity of the | |
| 4355 example). | |

| 15194 | 4371 8. Syntax patterns *:syn-pattern* *E401* *E402* |
| 7 | 4372 |
| 4373 In the syntax commands, a pattern must be surrounded by two identical | |
| 4374 characters. This is like it works for the ":s" command. The most common to | |
| 4375 use is the double quote. But if the pattern contains a double quote, you can | |
| 4376 use another character that is not used in the pattern. Examples: > | |
| 4377 :syntax region Comment start="/\*" end="\*/" | |
| 4378 :syntax region String start=+"+ end=+"+ skip=+\\"+ | |
| 4379 | |
| 4380 See |pattern| for the explanation of what a pattern is. Syntax patterns are | |
| 1624 | 4381 always interpreted like the 'magic' option is set, no matter what the actual |
| 7 | 4382 value of 'magic' is. And the patterns are interpreted like the 'l' flag is |
| 4383 not included in 'cpoptions'. This was done to make syntax files portable and | |
| 4384 independent of 'compatible' and 'magic' settings. | |
| 4385 | |
| 4386 Try to avoid patterns that can match an empty string, such as "[a-z]*". | |
| 4387 This slows down the highlighting a lot, because it matches everywhere. | |
| 4388 | |
| 4389 *:syn-pattern-offset* | |
| 4390 The pattern can be followed by a character offset. This can be used to | |
| 4391 change the highlighted part, and to change the text area included in the | |
| 4392 match or region (which only matters when trying to match other items). Both | |
| 4393 are relative to the matched pattern. The character offset for a skip | |
| 4394 pattern can be used to tell where to continue looking for an end pattern. | |
| 4395 | |
| 4396 The offset takes the form of "{what}={offset}" | |
| 4397 The {what} can be one of seven strings: | |
| 4398 | |
| 4399 ms Match Start offset for the start of the matched text | |
| 4400 me Match End offset for the end of the matched text | |
| 4401 hs Highlight Start offset for where the highlighting starts | |
| 4402 he Highlight End offset for where the highlighting ends | |
| 4403 rs Region Start offset for where the body of a region starts | |
| 4404 re Region End offset for where the body of a region ends | |
| 4405 lc Leading Context offset past "leading context" of pattern | |
| 4406 | |
| 4407 The {offset} can be: | |
| 4408 | |
| 4409 s start of the matched pattern | |
| 4410 s+{nr} start of the matched pattern plus {nr} chars to the right | |
| 4411 s-{nr} start of the matched pattern plus {nr} chars to the left | |
| 4412 e end of the matched pattern | |
| 4413 e+{nr} end of the matched pattern plus {nr} chars to the right | |
| 4414 e-{nr} end of the matched pattern plus {nr} chars to the left | |
| 4229 | 4415 {nr} (for "lc" only): start matching {nr} chars right of the start |
| 7 | 4416 |
| 4417 Examples: "ms=s+1", "hs=e-2", "lc=3". | |
| 4418 | |
| 4419 Although all offsets are accepted after any pattern, they are not always | |
| 4420 meaningful. This table shows which offsets are actually used: | |
| 4421 | |
| 4422 ms me hs he rs re lc ~ | |
| 4423 match item yes yes yes yes - - yes | |
| 4424 region item start yes - yes - yes - yes | |
| 4425 region item skip - yes - - - - yes | |
| 4426 region item end - yes - yes - yes yes | |
| 4427 | |
| 4428 Offsets can be concatenated, with a ',' in between. Example: > | |
| 4429 :syn match String /"[^"]*"/hs=s+1,he=e-1 | |
| 4430 < | |
| 4431 some "string" text | |
| 4432 ^^^^^^ highlighted | |
| 4433 | |
| 4434 Notes: | |
| 4435 - There must be no white space between the pattern and the character | |
| 4436 offset(s). | |
| 4437 - The highlighted area will never be outside of the matched text. | |
| 4438 - A negative offset for an end pattern may not always work, because the end | |
| 4439 pattern may be detected when the highlighting should already have stopped. | |

4442 Vim 7.2 release. |
| 7 | 4443 - The start of a match cannot be in a line other than where the pattern |
| 4444 matched. This doesn't work: "a\nb"ms=e. You can make the highlighting | |
| 4445 start in another line, this does work: "a\nb"hs=e. | |
| 4446 | |
| 4447 Example (match a comment but don't highlight the /* and */): > | |
| 4448 :syntax region Comment start="/\*"hs=e+1 end="\*/"he=s-1 | |
| 4449 < | |
| 4450 /* this is a comment */ | |
| 4451 ^^^^^^^^^^^^^^^^^^^ highlighted | |
| 4452 | |
| 4453 A more complicated Example: > | |
| 4454 :syn region Exa matchgroup=Foo start="foo"hs=s+2,rs=e+2 matchgroup=Bar end="bar"me=e-1,he=e-1,re=s-1 | |
| 4455 < | |
| 4456 abcfoostringbarabc | |
| 4457 mmmmmmmmmmm match | |
| 625 | 4458 sssrrreee highlight start/region/end ("Foo", "Exa" and "Bar") |
| 7 | 4459 |
| 4460 Leading context *:syn-lc* *:syn-leading* *:syn-context* | |
| 4461 | |
| 4462 Note: This is an obsolete feature, only included for backwards compatibility | |
| 4463 with previous Vim versions. It's now recommended to use the |/\@<=| construct | |
| 28010 | 4464 in the pattern. You can also often use |/\zs|. |
| 7 | 4465 |
| 4466 The "lc" offset specifies leading context -- a part of the pattern that must | |
| 4467 be present, but is not considered part of the match. An offset of "lc=n" will | |
| 4468 cause Vim to step back n columns before attempting the pattern match, allowing | |
| 4469 characters which have already been matched in previous patterns to also be | |
| 4470 used as leading context for this match. This can be used, for instance, to | |
| 4471 specify that an "escaping" character must not precede the match: > | |
| 4472 | |
| 4473 :syn match ZNoBackslash "[^\\]z"ms=s+1 | |
| 4474 :syn match WNoBackslash "[^\\]w"lc=1 | |
| 4475 :syn match Underline "_\+" | |
| 4476 < | |
| 4477 ___zzzz ___wwww | |
| 4478 ^^^ ^^^ matches Underline | |
| 4479 ^ ^ matches ZNoBackslash | |
| 4480 ^^^^ matches WNoBackslash | |
| 4481 | |
| 4482 The "ms" offset is automatically set to the same value as the "lc" offset, | |
| 4483 unless you set "ms" explicitly. | |
| 4484 | |
| 4485 | |
| 4486 Multi-line patterns *:syn-multi-line* | |
| 4487 | |
| 4488 The patterns can include "\n" to match an end-of-line. Mostly this works as | |
| 4489 expected, but there are a few exceptions. | |
| 4490 | |
| 4491 When using a start pattern with an offset, the start of the match is not | |
| 4492 allowed to start in a following line. The highlighting can start in a | |

4494 the match doesn't move to another line. |
| 7 | 4495 |
| 4496 The skip pattern can include the "\n", but the search for an end pattern will | |
| 4497 continue in the first character of the next line, also when that character is | |
| 4498 matched by the skip pattern. This is because redrawing may start in any line | |
| 4499 halfway a region and there is no check if the skip pattern started in a | |
| 4500 previous line. For example, if the skip pattern is "a\nb" and an end pattern | |
| 4501 is "b", the end pattern does match in the second line of this: > | |
| 4502 x x a | |
| 4503 b x x | |
| 4504 Generally this means that the skip pattern should not match any characters | |
| 4505 after the "\n". | |
| 4506 | |
| 4507 | |
| 4508 External matches *:syn-ext-match* | |
| 4509 | |
| 4510 These extra regular expression items are available in region patterns: | |
| 4511 | |
| 4780 | 4512 */\z(* */\z(\)* *E50* *E52* *E879* |
| 4073 | 4513 \z(\) Marks the sub-expression as "external", meaning that it can be |
| 4514 accessed from another pattern match. Currently only usable in | |
| 4515 defining a syntax region start pattern. | |
| 7 | 4516 |
| 4517 */\z1* */\z2* */\z3* */\z4* */\z5* | |
| 4518 \z1 ... \z9 */\z6* */\z7* */\z8* */\z9* *E66* *E67* | |
| 4519 Matches the same string that was matched by the corresponding | |
| 4520 sub-expression in a previous start pattern match. | |
| 4521 | |
| 4522 Sometimes the start and end patterns of a region need to share a common | |
| 4523 sub-expression. A common example is the "here" document in Perl and many Unix | |
| 4524 shells. This effect can be achieved with the "\z" special regular expression | |
| 4525 items, which marks a sub-expression as "external", in the sense that it can be | |
| 4526 referenced from outside the pattern in which it is defined. The here-document | |
| 4527 example, for instance, can be done like this: > | |
| 4528 :syn region hereDoc start="<<\z(\I\i*\)" end="^\z1$" | |
| 4529 | |
| 4530 As can be seen here, the \z actually does double duty. In the start pattern, | |
| 4531 it marks the "\(\I\i*\)" sub-expression as external; in the end pattern, it | |

4532 changes the \z1 back-reference into an external reference referring to the |
| 7 | 4533 first external sub-expression in the start pattern. External references can |
| 4534 also be used in skip patterns: > | |
| 26708 | 4535 :syn region foo start="start \z(\I\i*\)" skip="not end \z1" end="end \z1" |
| 7 | 4536 |
| 4537 Note that normal and external sub-expressions are completely orthogonal and | |
| 4538 indexed separately; for instance, if the pattern "\z(..\)\(..\)" is applied | |
| 4539 to the string "aabb", then \1 will refer to "bb" and \z1 will refer to "aa". | |
| 4540 Note also that external sub-expressions cannot be accessed as back-references | |
| 4541 within the same pattern like normal sub-expressions. If you want to use one | |
| 4542 sub-expression as both a normal and an external sub-expression, you can nest | |
| 4543 the two, as in "\(\z(...\)\)". | |
| 4544 | |
| 4545 Note that only matches within a single line can be used. Multi-line matches | |
| 4546 cannot be referred to. | |

| 4566 nextgroup=.., add=.. or remove=.. list with a "@" prefix. You can also use | |
| 4567 this notation to implicitly declare a cluster before specifying its contents. | |
| 7 | 4568 |
| 4569 Example: > | |
| 4570 :syntax match Thing "# [^#]\+ #" contains=@ThingMembers | |
| 4571 :syntax cluster ThingMembers contains=ThingMember1,ThingMember2 | |
| 4572 | |
| 4573 As the previous example suggests, modifications to a cluster are effectively | |
| 4574 retroactive; the membership of the cluster is checked at the last minute, so | |
| 4575 to speak: > | |
| 4576 :syntax keyword A aaa | |
| 4577 :syntax keyword B bbb | |
| 4578 :syntax cluster AandB contains=A | |
| 4579 :syntax match Stuff "( aaa bbb )" contains=@AandB | |
| 4580 :syntax cluster AandB add=B " now both keywords are matched in Stuff | |
| 4581 | |
| 4582 This also has implications for nested clusters: > | |
| 4583 :syntax keyword A aaa | |
| 4584 :syntax keyword B bbb | |
| 4585 :syntax cluster SmallGroup contains=B | |
| 4586 :syntax cluster BigGroup contains=A,@SmallGroup | |
| 4587 :syntax match Stuff "( aaa bbb )" contains=@BigGroup | |
| 4588 :syntax cluster BigGroup remove=B " no effect, since B isn't in BigGroup | |
| 4589 :syntax cluster SmallGroup remove=B " now bbb isn't matched within Stuff | |
| 2751 | 4590 < |
| 4591 *E848* | |
| 4592 The maximum number of clusters is 9767. | |

| 4594 ============================================================================== | |
| 15194 | 4595 10. Including syntax files *:syn-include* *E397* |
| 7 | 4596 |
| 4597 It is often useful for one language's syntax file to include a syntax file for | |
| 4598 a related language. Depending on the exact relationship, this can be done in | |
| 4599 two different ways: | |
| 4600 | |
| 4601 - If top-level syntax items in the included syntax file are to be | |
| 4602 allowed at the top level in the including syntax, you can simply use | |
| 4603 the |:runtime| command: > | |
| 4604 | |
| 4605 " In cpp.vim: | |
| 4606 :runtime! syntax/c.vim | |
| 4607 :unlet b:current_syntax | |
| 4608 | |
| 4609 < - If top-level syntax items in the included syntax file are to be | |
| 4610 contained within a region in the including syntax, you can use the | |
| 4611 ":syntax include" command: | |
| 4612 | |
| 4613 :sy[ntax] include [@{grouplist-name}] {file-name} | |
| 4614 | |
| 4615 All syntax items declared in the included file will have the | |
| 4616 "contained" flag added. In addition, if a group list is specified, | |
| 4617 all top-level syntax items in the included file will be added to | |
| 4618 that list. > | |
| 4619 | |
| 4620 " In perl.vim: | |
| 4621 :syntax include @Pod <sfile>:p:h/pod.vim | |
| 4622 :syntax region perlPOD start="^=head" end="^=cut" contains=@Pod | |
| 4623 < | |
| 4624 When {file-name} is an absolute path (starts with "/", "c:", "$VAR" | |
| 4625 or "<sfile>") that file is sourced. When it is a relative path | |
| 4626 (e.g., "syntax/pod.vim") the file is searched for in 'runtimepath'. | |
| 4627 All matching files are loaded. Using a relative path is | |
| 4628 recommended, because it allows a user to replace the included file | |
| 19574 | 4629 with their own version, without replacing the file that does the |
| 4630 ":syn include". | |
| 7 | 4631 |
| 2751 | 4632 *E847* |
| 4633 The maximum number of includes is 999. | |
| 4634 | |
| 7 | 4635 ============================================================================== |
| 15194 | 4636 11. Synchronizing *:syn-sync* *E403* *E404* |
| 7 | 4637 |
| 4638 Vim wants to be able to start redrawing in any position in the document. To | |
| 4639 make this possible it needs to know the syntax state at the position where | |
| 4640 redrawing starts. | |
| 4641 | |
| 4642 :sy[ntax] sync [ccomment [group-name] | minlines={N} | ...] | |
| 4643 | |
| 4644 There are four ways to synchronize: | |
| 4645 1. Always parse from the start of the file. | |
| 4646 |:syn-sync-first| | |
| 4647 2. Based on C-style comments. Vim understands how C-comments work and can | |
| 4648 figure out if the current line starts inside or outside a comment. | |
| 4649 |:syn-sync-second| | |
| 4650 3. Jumping back a certain number of lines and start parsing there. | |
| 4651 |:syn-sync-third| | |
| 4652 4. Searching backwards in the text for a pattern to sync on. | |
| 4653 |:syn-sync-fourth| | |
| 4654 | |
| 4655 *:syn-sync-maxlines* *:syn-sync-minlines* | |
| 4656 For the last three methods, the line range where the parsing can start is | |
| 4657 limited by "minlines" and "maxlines". | |
| 4658 | |
| 4659 If the "minlines={N}" argument is given, the parsing always starts at least | |
| 4660 that many lines backwards. This can be used if the parsing may take a few | |
| 4661 lines before it's correct, or when it's not possible to use syncing. | |
| 4662 | |
| 4663 If the "maxlines={N}" argument is given, the number of lines that are searched | |
| 4664 for a comment or syncing pattern is restricted to N lines backwards (after | |
| 4665 adding "minlines"). This is useful if you have few things to sync on and a | |
| 4666 slow machine. Example: > | |
| 6647 | 4667 :syntax sync maxlines=500 ccomment |
| 7 | 4668 < |
| 4669 *:syn-sync-linebreaks* | |
| 4670 When using a pattern that matches multiple lines, a change in one line may | |
| 4671 cause a pattern to no longer match in a previous line. This means has to | |
| 4672 start above where the change was made. How many lines can be specified with | |
| 4673 the "linebreaks" argument. For example, when a pattern may include one line | |
| 4674 break use this: > | |
| 4675 :syntax sync linebreaks=1 | |
| 4676 The result is that redrawing always starts at least one line before where a | |
| 4677 change was made. The default value for "linebreaks" is zero. Usually the | |
| 4678 value for "minlines" is bigger than "linebreaks". | |
| 4679 | |
| 4680 | |
| 4681 First syncing method: *:syn-sync-first* | |
| 4682 > | |
| 4683 :syntax sync fromstart | |
| 4684 | |
| 4685 The file will be parsed from the start. This makes syntax highlighting | |
| 4686 accurate, but can be slow for long files. Vim caches previously parsed text, | |
| 4687 so that it's only slow when parsing the text for the first time. However, | |
| 3224 | 4688 when making changes some part of the text needs to be parsed again (worst |
| 7 | 4689 case: to the end of the file). |
| 4690 | |
| 4691 Using "fromstart" is equivalent to using "minlines" with a very large number. | |
| 4692 | |
| 4693 | |
| 4694 Second syncing method: *:syn-sync-second* *:syn-sync-ccomment* | |
| 4695 | |
| 4696 For the second method, only the "ccomment" argument needs to be given. | |
| 4697 Example: > | |
| 4698 :syntax sync ccomment | |
| 4699 | |
| 4700 When Vim finds that the line where displaying starts is inside a C-style | |
| 4701 comment, the last region syntax item with the group-name "Comment" will be | |
| 4702 used. This requires that there is a region with the group-name "Comment"! | |
| 4703 An alternate group name can be specified, for example: > | |
| 4704 :syntax sync ccomment javaComment | |
| 4705 This means that the last item specified with "syn region javaComment" will be | |
| 4706 used for the detected C comment region. This only works properly if that | |
| 4707 region does have a start pattern "\/*" and an end pattern "*\/". | |
| 4708 | |
| 4709 The "maxlines" argument can be used to restrict the search to a number of | |
| 4710 lines. The "minlines" argument can be used to at least start a number of | |
| 4711 lines back (e.g., for when there is some construct that only takes a few | |
| 4712 lines, but it hard to sync on). | |
| 4713 | |
| 4714 Note: Syncing on a C comment doesn't work properly when strings are used | |
| 4715 that cross a line and contain a "*/". Since letting strings cross a line | |
| 4716 is a bad programming habit (many compilers give a warning message), and the | |
| 4717 chance of a "*/" appearing inside a comment is very small, this restriction | |
| 4718 is hardly ever noticed. | |
| 4719 | |
| 4720 | |
| 4721 Third syncing method: *:syn-sync-third* | |
| 4722 | |
| 4723 For the third method, only the "minlines={N}" argument needs to be given. | |
| 4724 Vim will subtract {N} from the line number and start parsing there. This | |
| 4725 means {N} extra lines need to be parsed, which makes this method a bit slower. | |
| 4726 Example: > | |
| 4727 :syntax sync minlines=50 | |
| 4728 | |
| 4729 "lines" is equivalent to "minlines" (used by older versions). | |
| 4730 | |
| 4731 | |
| 4732 Fourth syncing method: *:syn-sync-fourth* | |
| 4733 | |
| 4734 The idea is to synchronize on the end of a few specific regions, called a | |
| 4735 sync pattern. Only regions can cross lines, so when we find the end of some | |
| 4736 region, we might be able to know in which syntax item we are. The search | |
| 4737 starts in the line just above the one where redrawing starts. From there | |
| 4738 the search continues backwards in the file. | |
| 4739 | |
| 4740 This works just like the non-syncing syntax items. You can use contained | |
| 4741 matches, nextgroup, etc. But there are a few differences: | |
| 4742 - Keywords cannot be used. | |
| 4743 - The syntax items with the "sync" keyword form a completely separated group | |
| 4744 of syntax items. You can't mix syncing groups and non-syncing groups. | |
| 4745 - The matching works backwards in the buffer (line by line), instead of | |
| 4746 forwards. | |
| 4747 - A line continuation pattern can be given. It is used to decide which group | |
| 4748 of lines need to be searched like they were one line. This means that the | |
| 4749 search for a match with the specified items starts in the first of the | |
| 24103 | 4750 consecutive lines that contain the continuation pattern. |
| 7 | 4751 - When using "nextgroup" or "contains", this only works within one line (or |
| 4752 group of continued lines). | |
| 4753 - When using a region, it must start and end in the same line (or group of | |
| 4754 continued lines). Otherwise the end is assumed to be at the end of the | |
| 4755 line (or group of continued lines). | |
| 4756 - When a match with a sync pattern is found, the rest of the line (or group of | |
| 4757 continued lines) is searched for another match. The last match is used. | |
| 4758 This is used when a line can contain both the start end the end of a region | |
| 4759 (e.g., in a C-comment like /* this */, the last "*/" is used). | |
| 4760 | |
| 4761 There are two ways how a match with a sync pattern can be used: | |
| 4762 1. Parsing for highlighting starts where redrawing starts (and where the | |
| 4763 search for the sync pattern started). The syntax group that is expected | |
| 4764 to be valid there must be specified. This works well when the regions | |
| 4765 that cross lines cannot contain other regions. | |
| 4766 2. Parsing for highlighting continues just after the match. The syntax group | |
| 4767 that is expected to be present just after the match must be specified. | |
| 4768 This can be used when the previous method doesn't work well. It's much | |
| 4769 slower, because more text needs to be parsed. | |
| 4770 Both types of sync patterns can be used at the same time. | |
| 4771 | |
| 4772 Besides the sync patterns, other matches and regions can be specified, to | |
| 4773 avoid finding unwanted matches. | |
| 4774 | |
| 4775 [The reason that the sync patterns are given separately, is that mostly the | |
| 4776 search for the sync point can be much simpler than figuring out the | |
| 4777 highlighting. The reduced number of patterns means it will go (much) | |
| 4778 faster.] | |
| 4779 | |
| 4780 *syn-sync-grouphere* *E393* *E394* | |
| 4781 :syntax sync match {sync-group-name} grouphere {group-name} "pattern" .. | |
| 4782 | |
| 4783 Define a match that is used for syncing. {group-name} is the | |
| 4784 name of a syntax group that follows just after the match. Parsing | |
| 4785 of the text for highlighting starts just after the match. A region | |
| 4786 must exist for this {group-name}. The first one defined will be used. | |
| 4787 "NONE" can be used for when there is no syntax group after the match. | |
| 4788 | |
| 4789 *syn-sync-groupthere* | |
| 4790 :syntax sync match {sync-group-name} groupthere {group-name} "pattern" .. | |
| 4791 | |
| 4792 Like "grouphere", but {group-name} is the name of a syntax group that | |
| 4793 is to be used at the start of the line where searching for the sync | |
| 4794 point started. The text between the match and the start of the sync | |
| 4795 pattern searching is assumed not to change the syntax highlighting. | |
| 4796 For example, in C you could search backwards for "/*" and "*/". If | |
| 4797 "/*" is found first, you know that you are inside a comment, so the | |
| 4798 "groupthere" is "cComment". If "*/" is found first, you know that you | |
| 4799 are not in a comment, so the "groupthere" is "NONE". (in practice | |
| 4800 it's a bit more complicated, because the "/*" and "*/" could appear | |
| 4801 inside a string. That's left as an exercise to the reader...). | |
| 4802 | |
| 4803 :syntax sync match .. | |
| 4804 :syntax sync region .. | |
| 4805 | |
| 4806 Without a "groupthere" argument. Define a region or match that is | |
| 4807 skipped while searching for a sync point. | |
| 4808 | |
| 856 | 4809 *syn-sync-linecont* |
| 7 | 4810 :syntax sync linecont {pattern} |
| 4811 | |
| 4812 When {pattern} matches in a line, it is considered to continue in | |
| 4813 the next line. This means that the search for a sync point will | |
| 4814 consider the lines to be concatenated. | |
| 4815 | |
| 4816 If the "maxlines={N}" argument is given too, the number of lines that are | |
| 4817 searched for a match is restricted to N. This is useful if you have very | |
| 4818 few things to sync on and a slow machine. Example: > | |
| 4819 :syntax sync maxlines=100 | |
| 4820 | |
| 4821 You can clear all sync settings with: > | |
| 4822 :syntax sync clear | |
| 4823 | |
| 4824 You can clear specific sync patterns with: > | |
| 4825 :syntax sync clear {sync-group-name} .. | |
| 4826 | |
| 4827 ============================================================================== | |
| 15194 | 4828 12. Listing syntax items *:syntax* *:sy* *:syn* *:syn-list* |
| 7 | 4829 |
| 534 | 4830 This command lists all the syntax items: > |
| 7 | 4831 |
| 4832 :sy[ntax] [list] | |
| 4833 | |
| 4834 To show the syntax items for one syntax group: > | |
| 4835 | |
| 4836 :sy[ntax] list {group-name} | |
| 4837 | |
| 2581 | 4838 To list the syntax groups in one cluster: *E392* > |
| 7 | 4839 |
| 4840 :sy[ntax] list @{cluster-name} | |
| 4841 | |
| 4842 See above for other arguments for the ":syntax" command. | |
| 4843 | |
| 4844 Note that the ":syntax" command can be abbreviated to ":sy", although ":syn" | |
| 4845 is mostly used, because it looks better. | |
| 4846 | |
| 4847 ============================================================================== | |
| 15194 | 4848 13. Highlight command *:highlight* *:hi* *E28* *E411* *E415* |
| 7 | 4849 |
| 4850 There are three types of highlight groups: | |
| 4851 - The ones used for specific languages. For these the name starts with the | |
| 4852 name of the language. Many of these don't have any attributes, but are | |
| 4853 linked to a group of the second type. | |
| 4854 - The ones used for all syntax languages. | |
| 4855 - The ones used for the 'highlight' option. | |
| 4856 *hitest.vim* | |
| 4857 You can see all the groups currently active with this command: > | |
| 4858 :so $VIMRUNTIME/syntax/hitest.vim | |
| 4859 This will open a new window containing all highlight group names, displayed | |
| 4860 in their own color. | |
| 4861 | |
| 4862 *:colo* *:colorscheme* *E185* | |
| 2152 | 4863 :colo[rscheme] Output the name of the currently active color scheme. |
| 4864 This is basically the same as > | |
| 4865 :echo g:colors_name | |
| 4866 < In case g:colors_name has not been defined :colo will | |
| 4867 output "default". When compiled without the |+eval| | |
| 4868 feature it will output "unknown". | |
| 4869 | |
| 7 | 4870 :colo[rscheme] {name} Load color scheme {name}. This searches 'runtimepath' |

| 4918 :hi[ghlight] {group-name} NONE | |
| 4919 Disable the highlighting for one highlight group. It | |
| 4920 is _not_ set back to the default colors. | |
| 4921 | |
| 4922 :hi[ghlight] [default] {group-name} {key}={arg} .. | |
| 4923 Add a highlight group, or change the highlighting for | |
| 26100 | 4924 an existing group. If a given color name is not |
| 26148 | 4925 recognized, each `colors/lists/default.vim` found on |
| 26100 | 4926 |'runtimepath'| will be loaded. |
| 7 | 4927 See |highlight-args| for the {key}={arg} arguments. |
| 4928 See |:highlight-default| for the optional [default] | |
| 4929 argument. | |
| 4930 | |
| 4931 Normally a highlight group is added once when starting up. This sets the | |
| 4932 default values for the highlighting. After that, you can use additional | |
| 4933 highlight commands to change the arguments that you want to set to non-default | |
| 4934 values. The value "NONE" can be used to switch the value off or go back to | |
| 4935 the default value. | |
| 4936 | |
| 4937 A simple way to change colors is with the |:colorscheme| command. This loads | |
| 4938 a file with ":highlight" commands such as this: > | |
| 4939 | |
| 4940 :hi Comment gui=bold | |
| 4941 | |
| 4942 Note that all settings that are not included remain the same, only the | |
| 4943 specified field is used, and settings are merged with previous ones. So, the | |
| 4944 result is like this single command has been used: > | |
| 4945 :hi Comment term=bold ctermfg=Cyan guifg=#80a0ff gui=bold | |
| 4946 < | |
| 856 | 4947 *:highlight-verbose* |
| 448 | 4948 When listing a highlight group and 'verbose' is non-zero, the listing will |
| 4949 also tell where it was last set. Example: > | |
| 4950 :verbose hi Comment | |
| 4951 < Comment xxx term=bold ctermfg=4 guifg=Blue ~ | |
| 856 | 4952 Last set from /home/mool/vim/vim7/runtime/syntax/syncolor.vim ~ |
| 448 | 4953 |
| 484 | 4954 When ":hi clear" is used then the script where this command is used will be |
| 4955 mentioned for the default values. See |:verbose-cmd| for more information. | |
| 448 | 4956 |
| 7 | 4957 *highlight-args* *E416* *E417* *E423* |
| 4958 There are three types of terminals for highlighting: | |
| 4959 term a normal terminal (vt100, xterm) | |
| 18972 | 4960 cterm a color terminal (MS-Windows console, color-xterm, these have the "Co" |
| 7 | 4961 termcap entry) |
| 4962 gui the GUI | |
| 4963 | |
| 4964 For each type the highlighting can be given. This makes it possible to use | |
| 4965 the same syntax file on all terminals, and use the optimal highlighting. | |

4989 then "underline" is used. In general "undercurl" and "strikethrough" |
| 20753 | 4990 are only available in the GUI and some terminals. The color is set |
| 4991 with |highlight-guisp| or |highlight-ctermul|. You can try these | |
| 4992 termcap entries to make undercurl work in a terminal: > | |
| 4993 let &t_Cs = "\e[4:3m" | |
| 4994 let &t_Ce = "\e[4:0m" | |

| 7 | 4996 |
| 4997 start={term-list} *highlight-start* *E422* | |
| 4998 stop={term-list} *term-list* *highlight-stop* | |
| 4999 These lists of terminal codes can be used to get | |
| 5000 non-standard attributes on a terminal. | |
| 5001 | |
| 5002 The escape sequence specified with the "start" argument | |
| 5003 is written before the characters in the highlighted | |
| 5004 area. It can be anything that you want to send to the | |
| 5005 terminal to highlight this area. The escape sequence | |
| 5006 specified with the "stop" argument is written after the | |
| 5007 highlighted area. This should undo the "start" argument. | |
| 5008 Otherwise the screen will look messed up. | |
| 5009 | |
| 5010 The {term-list} can have two forms: | |
| 5011 | |
| 5012 1. A string with escape sequences. | |
| 5013 This is any string of characters, except that it can't start with | |
| 5014 "t_" and blanks are not allowed. The <> notation is recognized | |
| 5015 here, so you can use things like "<Esc>" and "<Space>". Example: | |
| 5016 start=<Esc>[27h;<Esc>[<Space>r; | |
| 5017 | |
| 5018 2. A list of terminal codes. | |
| 5019 Each terminal code has the form "t_xx", where "xx" is the name of | |
| 5020 the termcap entry. The codes have to be separated with commas. | |
| 5021 White space is not allowed. Example: | |
| 5022 start=t_C1,t_BL | |
| 5023 The terminal codes must exist for this to work. | |
| 5024 | |
| 5025 | |
| 5026 2. highlight arguments for color terminals | |
| 5027 | |
| 5028 cterm={attr-list} *highlight-cterm* | |
| 5029 See above for the description of {attr-list} |attr-list|. | |
| 5030 The "cterm" argument is likely to be different from "term", when | |
| 5031 colors are used. For example, in a normal terminal comments could | |
| 5032 be underlined, in a color terminal they can be made Blue. | |
| 16808 | 5033 Note: Some terminals (e.g., DOS console) can't mix these attributes |
| 5034 with coloring. To be portable, use only one of "cterm=" OR "ctermfg=" | |
| 5035 OR "ctermbg=". | |

| 7 | 5043 The {color-nr} argument is a color number. Its range is zero to |
| 5044 (not including) the number given by the termcap entry "Co". | |
| 5045 The actual color with this number depends on the type of terminal | |
| 5046 and its settings. Sometimes the color also depends on the settings of | |
| 5047 "cterm". For example, on some systems "cterm=bold ctermfg=3" gives | |
| 5048 another color, on others you just get color 3. | |
| 5049 | |
| 5050 For an xterm this depends on your resources, and is a bit | |
| 5051 unpredictable. See your xterm documentation for the defaults. The | |
| 5052 colors for a color-xterm can be changed from the .Xdefaults file. | |
| 5053 Unfortunately this means that it's not possible to get the same colors | |
| 5054 for each user. See |xterm-color| for info about color xterms. | |
| 24751 | 5055 *tmux* |
| 5056 When using tmux you may want to use this in the tmux config: > | |
| 5057 # tmux colors | |
| 24911 | 5058 set -s default-terminal "tmux-256color" |
| 5059 set -as terminal-overrides ",*-256color:Tc" | |

| 7 | 5063 |
| 18972 | 5064 The MS-Windows standard colors are fixed (in a console window), so |
| 5065 these have been used for the names. But the meaning of color names in | |
| 5066 X11 are fixed, so these color settings have been used, to make the | |
| 7 | 5067 highlighting settings portable (complicated, isn't it?). The |
| 5068 following names are recognized, with the color number used: | |
| 5069 | |
| 5070 *cterm-colors* | |
| 5071 NR-16 NR-8 COLOR NAME ~ | |
| 5072 0 0 Black | |
| 5073 1 4 DarkBlue | |
| 5074 2 2 DarkGreen | |
| 5075 3 6 DarkCyan | |
| 5076 4 1 DarkRed | |
| 5077 5 5 DarkMagenta | |
| 5078 6 3 Brown, DarkYellow | |
| 5079 7 7 LightGray, LightGrey, Gray, Grey | |
| 5080 8 0* DarkGray, DarkGrey | |
| 5081 9 4* Blue, LightBlue | |
| 5082 10 2* Green, LightGreen | |
| 5083 11 6* Cyan, LightCyan | |
| 5084 12 1* Red, LightRed | |
| 5085 13 5* Magenta, LightMagenta | |
| 5086 14 3* Yellow, LightYellow | |
| 5087 15 7* White | |
| 5088 | |
| 5089 The number under "NR-16" is used for 16-color terminals ('t_Co' | |
| 5090 greater than or equal to 16). The number under "NR-8" is used for | |
| 5091 8-color terminals ('t_Co' less than 16). The '*' indicates that the | |
| 5092 bold attribute is set for ctermfg. In many 8-color terminals (e.g., | |
| 5093 "linux"), this causes the bright colors to appear. This doesn't work | |
| 5094 for background colors! Without the '*' the bold attribute is removed. | |
| 5095 If you want to set the bold attribute in a different way, put a | |
| 5096 "cterm=" argument AFTER the "ctermfg=" or "ctermbg=" argument. Or use | |
| 5097 a number instead of a color name. | |
| 5098 | |
| 5099 The case of the color names is ignored. | |

5102 Blue is 12, DarkGray is 8 etc. |
| 7 | 5103 |
| 5104 Note that for some color terminals these names may result in the wrong | |
| 5105 colors! | |

| 6697 | 5107 You can also use "NONE" to remove the color. |
| 5108 | |
| 7 | 5109 *:hi-normal-cterm* |
| 5110 When setting the "ctermfg" or "ctermbg" colors for the Normal group, | |
| 5111 these will become the colors used for the non-highlighted text. | |
| 5112 Example: > | |
| 5113 :highlight Normal ctermfg=grey ctermbg=darkblue | |
| 5114 < When setting the "ctermbg" color for the Normal group, the | |
| 11473 | 5115 'background' option will be adjusted automatically, under the |
| 5116 condition that the color is recognized and 'background' was not set | |
| 5117 explicitly. This causes the highlight groups that depend on | |
| 5118 'background' to change! This means you should set the colors for | |
| 5119 Normal first, before setting other colors. | |
| 16208 | 5120 When a color scheme is being used, changing 'background' causes it to |
| 7 | 5121 be reloaded, which may reset all colors (including Normal). First |

| 7 | 5123 |
| 5124 When you have set "ctermfg" or "ctermbg" for the Normal group, Vim | |
| 5125 needs to reset the color when exiting. This is done with the "op" | |
| 5126 termcap entry |t_op|. If this doesn't work correctly, try setting the | |
| 5127 't_op' option in your .vimrc. | |

| 5148 font={font-name} *highlight-font* | |
| 5149 font-name is the name of a font, as it is used on the system Vim | |

| 5151 font=-misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1 | |
| 5152 < | |
| 5153 The font-name "NONE" can be used to revert to the default font. | |
| 5154 When setting the font for the "Normal" group, this becomes the default | |
| 5155 font (until the 'guifont' option is changed; the last one set is | |
| 5156 used). | |
| 28379 | 5157 The following only works with Motif, not with other GUIs: |
| 7 | 5158 When setting the font for the "Menu" group, the menus will be changed. |
| 5159 When setting the font for the "Tooltip" group, the tooltips will be | |
| 5160 changed. | |

| 5162 character size as the default font! Otherwise redrawing problems will | |

5383 WildMenu Current match in 'wildmenu' completion. |
| 7 | 5384 |
| 523 | 5385 *hl-User1* *hl-User1..9* *hl-User9* |
| 7 | 5386 The 'statusline' syntax allows the use of 9 different highlights in the |
| 237 | 5387 statusline and ruler (via 'rulerformat'). The names are User1 to User9. |
| 7 | 5388 |
| 1624 | 5389 For the GUI you can use the following groups to set the colors for the menu, |
| 7 | 5390 scrollbars and tooltips. They don't have defaults. This doesn't work for the |
| 5391 Win32 GUI. Only three highlight arguments have any effect here: font, guibg, | |
| 5392 and guifg. | |
| 5393 | |
| 5394 *hl-Menu* | |
| 5395 Menu Current font, background and foreground colors of the menus. | |

| 5398 | |
| 28379 | 5399 NOTE: For Motif the font argument actually |
| 7 | 5400 specifies a fontset at all times, no matter if 'guifontset' is |
| 5401 empty, and as such it is tied to the current |:language| when | |

| 5418 ============================================================================== | |
| 15194 | 5419 14. Linking groups *:hi-link* *:highlight-link* *E412* *E413* |
| 7 | 5420 |
| 5421 When you want to use the same highlighting for several syntax groups, you | |
| 5422 can do this more easily by linking the groups into one common highlight | |
| 5423 group, and give the color attributes only for that group. | |
| 5424 | |
| 5425 To set a link: | |
| 5426 | |
| 5427 :hi[ghlight][!] [default] link {from-group} {to-group} | |
| 5428 | |
| 5429 To remove a link: | |
| 5430 | |
| 5431 :hi[ghlight][!] [default] link {from-group} NONE | |
| 5432 | |
| 5433 Notes: *E414* | |
| 5434 - If the {from-group} and/or {to-group} doesn't exist, it is created. You | |
| 5435 don't get an error message for a non-existing group. | |
| 5436 - As soon as you use a ":highlight" command for a linked group, the link is | |
| 5437 removed. | |
| 5438 - If there are already highlight settings for the {from-group}, the link is | |
| 5439 not made, unless the '!' is given. For a ":highlight link" command in a | |
| 5440 sourced file, you don't get an error message. This can be used to skip | |
| 5441 links for groups that already have settings. | |
| 5442 | |
| 5443 *:hi-default* *:highlight-default* | |
| 5444 The [default] argument is used for setting the default highlighting for a | |
| 5445 group. If highlighting has already been specified for the group the command | |
| 5446 will be ignored. Also when there is an existing link. | |
| 5447 | |
| 5448 Using [default] is especially useful to overrule the highlighting of a | |
| 5449 specific syntax file. For example, the C syntax file contains: > | |
| 5450 :highlight default link cComment Comment | |
| 5451 If you like Question highlighting for C comments, put this in your vimrc file: > | |
| 5452 :highlight link cComment Question | |
| 5453 Without the "default" in the C syntax file, the highlighting would be | |
| 5454 overruled when the syntax file is loaded. | |
| 5455 | |
| 23047 | 5456 To have a link survive `:highlight clear`, which is useful if you have |
| 5457 highlighting for a specific filetype and you want to keep it when selecting | |
| 5458 another color scheme, put a command like this in the | |
| 5459 "after/syntax/{filetype}.vim" file: > | |
| 5460 highlight! default link cComment Question | |
| 5461 | |
| 7 | 5462 ============================================================================== |
| 15194 | 5463 15. Cleaning up *:syn-clear* *E391* |
| 7 | 5464 |
| 5465 If you want to clear the syntax stuff for the current buffer, you can use this | |
| 5466 command: > | |
| 5467 :syntax clear | |
| 5468 | |
| 5469 This command should be used when you want to switch off syntax highlighting, | |
| 5470 or when you want to switch to using another syntax. It's normally not needed | |
| 5471 in a syntax file itself, because syntax is cleared by the autocommands that | |
| 5472 load the syntax file. | |
| 5473 The command also deletes the "b:current_syntax" variable, since no syntax is | |
| 5474 loaded after this command. | |
| 5475 | |
| 16944 | 5476 To clean up specific syntax groups for the current buffer: > |
| 5477 :syntax clear {group-name} .. | |
| 5478 This removes all patterns and keywords for {group-name}. | |
| 5479 | |
| 5480 To clean up specific syntax group lists for the current buffer: > | |
| 5481 :syntax clear @{grouplist-name} .. | |
| 5482 This sets {grouplist-name}'s contents to an empty list. | |
| 5483 | |
| 5484 *:syntax-off* *:syn-off* | |
| 7 | 5485 If you want to disable syntax highlighting for all buffers, you need to remove |
| 5486 the autocommands that load the syntax files: > | |
| 5487 :syntax off | |
| 5488 | |
| 5489 What this command actually does, is executing the command > | |
| 5490 :source $VIMRUNTIME/syntax/nosyntax.vim | |
| 5491 See the "nosyntax.vim" file for details. Note that for this to work | |
| 5492 $VIMRUNTIME must be valid. See |$VIMRUNTIME|. | |
| 5493 | |
| 5494 *:syntax-reset* *:syn-reset* | |
| 5495 If you have changed the colors and messed them up, use this command to get the | |
| 5496 defaults back: > | |
| 5497 | |
| 5498 :syntax reset | |
| 5499 | |

5502 |
| 7 | 5503 This doesn't change the colors for the 'highlight' option. |
| 5504 | |
| 5505 Note that the syntax colors that you set in your vimrc file will also be reset | |
| 5506 back to their Vim default. | |
| 5507 Note that if you are using a color scheme, the colors defined by the color | |
| 5508 scheme for syntax highlighting will be lost. | |
| 5509 | |
| 5510 What this actually does is: > | |
| 5511 | |
| 5512 let g:syntax_cmd = "reset" | |
| 5513 runtime! syntax/syncolor.vim | |
| 5514 | |
| 5515 Note that this uses the 'runtimepath' option. | |
| 5516 | |
| 5517 *syncolor* | |
| 5518 If you want to use different colors for syntax highlighting, you can add a Vim | |
| 5519 script file to set these colors. Put this file in a directory in | |
| 5520 'runtimepath' which comes after $VIMRUNTIME, so that your settings overrule | |
| 5521 the default colors. This way these colors will be used after the ":syntax | |
| 5522 reset" command. | |
| 5523 | |
| 5524 For Unix you can use the file ~/.vim/after/syntax/syncolor.vim. Example: > | |
| 5525 | |
| 5526 if &background == "light" | |
| 5527 highlight comment ctermfg=darkgreen guifg=darkgreen | |
| 5528 else | |
| 5529 highlight comment ctermfg=green guifg=green | |
| 5530 endif | |
| 26219 | 5531 < |
| 24 | 5532 *E679* |
| 5533 Do make sure this syncolor.vim script does not use a "syntax on", set the | |
| 5534 'background' option or uses a "colorscheme" command, because it results in an | |
| 5535 endless loop. | |
| 5536 | |
| 7 | 5537 Note that when a color scheme is used, there might be some confusion whether |
| 5538 your defined colors are to be used or the colors from the scheme. This | |
| 5539 depends on the color scheme file. See |:colorscheme|. | |
| 5540 | |
| 5541 *syntax_cmd* | |
| 5542 The "syntax_cmd" variable is set to one of these values when the | |
| 5543 syntax/syncolor.vim files are loaded: | |
| 26219 | 5544 "on" `:syntax on` command. Highlight colors are overruled but |
| 7 | 5545 links are kept |
| 26219 | 5546 "enable" `:syntax enable` command. Only define colors for groups that |
| 5547 don't have highlighting yet. Use `:highlight default` . | |
| 5548 "reset" `:syntax reset` command or loading a color scheme. Define all | |
| 7 | 5549 the colors. |
| 5550 "skip" Don't define colors. Used to skip the default settings when a | |
| 5551 syncolor.vim file earlier in 'runtimepath' has already set | |
| 5552 them. | |
| 5553 | |
| 5554 ============================================================================== | |
| 15194 | 5555 16. Highlighting tags *tag-highlight* |
| 7 | 5556 |
| 5557 If you want to highlight all the tags in your file, you can use the following | |
| 5558 mappings. | |
| 5559 | |
| 5560 <F11> -- Generate tags.vim file, and highlight tags. | |
| 5561 <F12> -- Just highlight tags based on existing tags.vim file. | |
| 5562 > | |
| 5563 :map <F11> :sp tags<CR>:%s/^\([^ :]*:\)\=\([^ ]*\).*/syntax keyword Tag \2/<CR>:wq! tags.vim<CR>/^<CR><F12> | |
| 5564 :map <F12> :so tags.vim<CR> | |
| 5565 | |
| 5566 WARNING: The longer the tags file, the slower this will be, and the more | |
| 5567 memory Vim will consume. | |
| 5568 | |
| 5569 Only highlighting typedefs, unions and structs can be done too. For this you | |
| 28141 | 5570 must use Universal Ctags (found at https://ctags.io) or Exuberant ctags (found |
| 5571 at http://ctags.sf.net). | |
| 7 | 5572 |
| 5573 Put these lines in your Makefile: | |
| 5574 | |
| 28141 | 5575 # Make a highlight file for types. Requires Universal/Exuberant ctags and awk |
| 7 | 5576 types: types.vim |
| 5577 types.vim: *.[ch] | |

| 7 | 5579 awk 'BEGIN{printf("syntax keyword Type\t")}\ |
| 5580 {printf("%s ", $$1)}END{print ""}' > $@ | |
| 5581 | |
| 5582 And put these lines in your .vimrc: > | |
| 5583 | |
| 5584 " load the types.vim highlighting file, if it exists | |
| 27903 | 5585 autocmd BufRead,BufNewFile *.[ch] let fname = expand('<afile>:p:h') .. '/types.vim' |

5620 ============================================================================== |
| 15194 | 5621 18. Color xterms *xterm-color* *color-xterm* |
| 7 | 5622 |
| 5623 Most color xterms have only eight colors. If you don't get colors with the | |
| 5624 default setup, it should work with these lines in your .vimrc: > | |
| 5625 :if &term =~ "xterm" | |
| 5626 : if has("terminfo") | |
| 5627 : set t_Co=8 | |
| 5628 : set t_Sf=<Esc>[3%p1%dm | |
| 5629 : set t_Sb=<Esc>[4%p1%dm | |
| 5630 : else | |
| 5631 : set t_Co=8 | |
| 5632 : set t_Sf=<Esc>[3%dm | |
| 5633 : set t_Sb=<Esc>[4%dm | |
| 5634 : endif | |
| 5635 :endif | |
| 5636 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 5637 | |
| 5638 You might want to change the first "if" to match the name of your terminal, | |
| 5639 e.g. "dtterm" instead of "xterm". | |
| 5640 | |
| 5641 Note: Do these settings BEFORE doing ":syntax on". Otherwise the colors may | |
| 5642 be wrong. | |
| 5643 *xiterm* *rxvt* | |
| 5644 The above settings have been mentioned to work for xiterm and rxvt too. | |
| 5645 But for using 16 colors in an rxvt these should work with terminfo: > | |
| 5646 :set t_AB=<Esc>[%?%p1%{8}%<%t25;%p1%{40}%+%e5;%p1%{32}%+%;%dm | |
| 5647 :set t_AF=<Esc>[%?%p1%{8}%<%t22;%p1%{30}%+%e1;%p1%{22}%+%;%dm | |
| 5648 < | |
| 5649 *colortest.vim* | |
| 5650 To test your color setup, a file has been included in the Vim distribution. | |
| 671 | 5651 To use it, execute this command: > |
| 5652 :runtime syntax/colortest.vim | |
| 7 | 5653 |
| 237 | 5654 Some versions of xterm (and other terminals, like the Linux console) can |
| 7 | 5655 output lighter foreground colors, even though the number of colors is defined |
| 5656 at 8. Therefore Vim sets the "cterm=bold" attribute for light foreground | |
| 5657 colors, when 't_Co' is 8. | |
| 5658 | |
| 5659 *xfree-xterm* | |
| 5660 To get 16 colors or more, get the newest xterm version (which should be | |
| 237 | 5661 included with XFree86 3.3 and later). You can also find the latest version |
| 7 | 5662 at: > |
| 5663 http://invisible-island.net/xterm/xterm.html | |
| 5664 Here is a good way to configure it. This uses 88 colors and enables the | |
| 5665 termcap-query feature, which allows Vim to ask the xterm how many colors it | |
| 5666 supports. > | |
| 5667 ./configure --disable-bold-color --enable-88-color --enable-tcap-query | |
| 5668 If you only get 8 colors, check the xterm compilation settings. | |
| 5669 (Also see |UTF8-xterm| for using this xterm with UTF-8 character encoding). | |
| 5670 | |
| 5671 This xterm should work with these lines in your .vimrc (for 16 colors): > | |
| 5672 :if has("terminfo") | |
| 5673 : set t_Co=16 | |
| 5674 : set t_AB=<Esc>[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{92}%+%;%dm | |
| 5675 : set t_AF=<Esc>[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{82}%+%;%dm | |
| 5676 :else | |
| 5677 : set t_Co=16 | |
| 5678 : set t_Sf=<Esc>[3%dm | |
| 5679 : set t_Sb=<Esc>[4%dm | |
| 5680 :endif | |
| 5681 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 5682 | |
| 5683 Without |+terminfo|, Vim will recognize these settings, and automatically | |
| 5684 translate cterm colors of 8 and above to "<Esc>[9%dm" and "<Esc>[10%dm". | |
| 5685 Colors above 16 are also translated automatically. | |
| 5686 | |
| 5687 For 256 colors this has been reported to work: > | |
| 5688 | |
| 5689 :set t_AB=<Esc>[48;5;%dm | |
| 5690 :set t_AF=<Esc>[38;5;%dm | |
| 5691 | |
| 5692 Or just set the TERM environment variable to "xterm-color" or "xterm-16color" | |
| 5693 and try if that works. | |
| 5694 | |
| 5695 You probably want to use these X resources (in your ~/.Xdefaults file): | |
| 5696 XTerm*color0: #000000 | |
| 5697 XTerm*color1: #c00000 | |
| 5698 XTerm*color2: #008000 | |
| 5699 XTerm*color3: #808000 | |
| 5700 XTerm*color4: #0000c0 | |
| 5701 XTerm*color5: #c000c0 | |
| 5702 XTerm*color6: #008080 | |
| 5703 XTerm*color7: #c0c0c0 | |
| 5704 XTerm*color8: #808080 | |
| 5705 XTerm*color9: #ff6060 | |
| 5706 XTerm*color10: #00ff00 | |
| 5707 XTerm*color11: #ffff00 | |
| 5708 XTerm*color12: #8080ff | |
| 5709 XTerm*color13: #ff40ff | |
| 5710 XTerm*color14: #00ffff | |
| 5711 XTerm*color15: #ffffff | |
| 5712 Xterm*cursorColor: Black | |
| 5713 | |
| 5714 [Note: The cursorColor is required to work around a bug, which changes the | |
| 5715 cursor color to the color of the last drawn text. This has been fixed by a | |
| 1125 | 5716 newer version of xterm, but not everybody is using it yet.] |
| 7 | 5717 |
| 5718 To get these right away, reload the .Xdefaults file to the X Option database | |
| 5719 Manager (you only need to do this when you just changed the .Xdefaults file): > | |
| 5720 xrdb -merge ~/.Xdefaults | |
| 5721 < | |
| 5722 *xterm-blink* *xterm-blinking-cursor* | |
| 5723 To make the cursor blink in an xterm, see tools/blink.c. Or use Thomas | |
| 5724 Dickey's xterm above patchlevel 107 (see above for where to get it), with | |
| 5725 these resources: | |
| 5726 XTerm*cursorBlink: on | |
| 5727 XTerm*cursorOnTime: 400 | |
| 5728 XTerm*cursorOffTime: 250 | |
| 5729 XTerm*cursorColor: White | |
| 5730 | |
| 5731 *hpterm-color* | |
| 1125 | 5732 These settings work (more or less) for an hpterm, which only supports 8 |
| 7 | 5733 foreground colors: > |
| 5734 :if has("terminfo") | |
| 5735 : set t_Co=8 | |
| 5736 : set t_Sf=<Esc>[&v%p1%dS | |
| 5737 : set t_Sb=<Esc>[&v7S | |
| 5738 :else | |
| 5739 : set t_Co=8 | |
| 5740 : set t_Sf=<Esc>[&v%dS | |
| 5741 : set t_Sb=<Esc>[&v7S | |
| 5742 :endif | |
| 5743 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 5744 | |
| 5745 *Eterm* *enlightened-terminal* | |
| 5746 These settings have been reported to work for the Enlightened terminal | |
| 5747 emulator, or Eterm. They might work for all xterm-like terminals that use the | |
| 5748 bold attribute to get bright colors. Add an ":if" like above when needed. > | |
| 5749 :set t_Co=16 | |
| 5750 :set t_AF=^[[%?%p1%{8}%<%t3%p1%d%e%p1%{22}%+%d;1%;m | |
| 5751 :set t_AB=^[[%?%p1%{8}%<%t4%p1%d%e%p1%{32}%+%d;1%;m | |
| 5752 < | |
| 5753 *TTpro-telnet* | |
| 5754 These settings should work for TTpro telnet. Tera Term Pro is a freeware / | |
| 5755 open-source program for MS-Windows. > | |
| 5756 set t_Co=16 | |
| 5757 set t_AB=^[[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{32}%+5;%;%dm | |
| 5758 set t_AF=^[[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{22}%+1;%;%dm | |
| 5759 Also make sure TTpro's Setup / Window / Full Color is enabled, and make sure | |
| 5760 that Setup / Font / Enable Bold is NOT enabled. | |
