| 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 | |
| 23 1. Quick start |:syn-qstart| | |

| 41 19. When syntax is slow |:syntime| | |
| 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 | |
| 18343 | 63 are in the "/usr/vim/vim81/syntax" directory, set $VIMRUNTIME to |
| 64 "/usr/vim/vim81". You must do this in the shell, before starting Vim. | |

70 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 | |
| 82 NOTE: The syntax files on MS-DOS and Windows have lines that end in <CR><NL>. | |
| 83 The files for Unix end in <NL>. This means you should use the right type of | |
| 84 file for your system. Although on MS-DOS and Windows the right format is | |
| 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 |
| 218 an error when using other characters. | |
| 7 | 219 |
| 220 To be able to allow each user to pick his favorite set of colors, there must | |
| 221 be preferred names for highlight groups that are common for many languages. | |
| 222 These are the suggested group names (if syntax highlighting works properly | |
| 223 you can see the actual color, except for "Ignore"): | |
| 224 | |
| 225 *Comment any comment | |
| 226 | |
| 227 *Constant any constant | |
| 228 String a string constant: "this is a string" | |
| 229 Character a character constant: 'c', '\n' | |
| 230 Number a number constant: 234, 0xff | |
| 231 Boolean a boolean constant: TRUE, false | |
| 232 Float a floating point constant: 2.3e10 | |
| 233 | |
| 234 *Identifier any variable name | |
| 235 Function function name (also: methods for classes) | |
| 236 | |
| 237 *Statement any statement | |
| 238 Conditional if, then, else, endif, switch, etc. | |
| 239 Repeat for, do, while, etc. | |
| 240 Label case, default, etc. | |
| 241 Operator "sizeof", "+", "*", etc. | |
| 242 Keyword any other keyword | |
| 243 Exception try, catch, throw | |
| 244 | |
| 245 *PreProc generic Preprocessor | |
| 246 Include preprocessor #include | |
| 247 Define preprocessor #define | |
| 248 Macro same as Define | |
| 249 PreCondit preprocessor #if, #else, #endif, etc. | |
| 250 | |
| 251 *Type int, long, char, etc. | |
| 252 StorageClass static, register, volatile, etc. | |
| 253 Structure struct, union, enum, etc. | |
| 254 Typedef A typedef | |
| 255 | |
| 256 *Special any special symbol | |
| 257 SpecialChar special character in a constant | |
| 258 Tag you can use CTRL-] on this | |
| 259 Delimiter character that needs attention | |
| 260 SpecialComment special things inside a comment | |
| 261 Debug debugging statements | |
| 262 | |
| 263 *Underlined text that stands out, HTML links | |

265 *Ignore left blank, hidden |hl-Ignore| |
| 7 | 266 |
| 267 *Error any erroneous construct | |
| 268 | |
| 269 *Todo anything that needs extra attention; mostly the | |
| 270 keywords TODO FIXME and XXX | |
| 271 | |
| 272 The names marked with * are the preferred groups; the others are minor groups. | |
| 273 For the preferred groups, the "syntax.vim" file contains default highlighting. | |
| 274 The minor groups are linked to the preferred groups, so they get the same | |
| 275 highlighting. You can override these defaults by using ":highlight" commands | |
| 276 after sourcing the "syntax.vim" file. | |
| 277 | |
| 278 Note that highlight group names are not case sensitive. "String" and "string" | |
| 279 can be used for the same group. | |
| 280 | |
| 281 The following names are reserved and cannot be used as a group name: | |

| 289 3. Syntax loading procedure *syntax-loading* | |
| 290 | |
| 291 This explains the details that happen when the command ":syntax enable" is | |
| 292 issued. When Vim initializes itself, it finds out where the runtime files are | |
| 293 located. This is used here as the variable |$VIMRUNTIME|. | |
| 294 | |
| 295 ":syntax enable" and ":syntax on" do the following: | |
| 296 | |
| 297 Source $VIMRUNTIME/syntax/syntax.vim | |
| 298 | | |
| 299 +- Clear out any old syntax by sourcing $VIMRUNTIME/syntax/nosyntax.vim | |
| 300 | | |
| 301 +- Source first syntax/synload.vim in 'runtimepath' | |
| 302 | | | |
| 303 | +- Setup the colors for syntax highlighting. If a color scheme is | |
| 304 | | defined it is loaded again with ":colors {name}". Otherwise | |
| 305 | | ":runtime! syntax/syncolor.vim" is used. ":syntax on" overrules | |
| 306 | | existing colors, ":syntax enable" only sets groups that weren't | |
| 307 | | set yet. | |
| 308 | | | |
| 309 | +- Set up syntax autocmds to load the appropriate syntax file when | |
| 310 | | the 'syntax' option is set. *synload-1* | |
| 311 | | | |
| 312 | +- Source the user's optional file, from the |mysyntaxfile| variable. | |
| 313 | This is for backwards compatibility with Vim 5.x only. *synload-2* | |
| 314 | | |
| 315 +- Do ":filetype on", which does ":runtime! filetype.vim". It loads any | |
| 316 | filetype.vim files found. It should always Source | |
| 317 | $VIMRUNTIME/filetype.vim, which does the following. | |
| 318 | | | |
| 319 | +- Install autocmds based on suffix to set the 'filetype' option | |
| 320 | | This is where the connection between file name and file type is | |
| 321 | | made for known file types. *synload-3* | |
| 322 | | | |
| 323 | +- Source the user's optional file, from the *myfiletypefile* | |
| 324 | | variable. This is for backwards compatibility with Vim 5.x only. | |
| 325 | | *synload-4* | |
| 326 | | | |
| 327 | +- Install one autocommand which sources scripts.vim when no file | |
| 328 | | type was detected yet. *synload-5* | |
| 329 | | | |
| 330 | +- Source $VIMRUNTIME/menu.vim, to setup the Syntax menu. |menu.vim| | |
| 331 | | |
| 332 +- Install a FileType autocommand to set the 'syntax' option when a file | |
| 333 | type has been detected. *synload-6* | |
| 334 | | |
| 335 +- Execute syntax autocommands to start syntax highlighting for each | |
| 336 already loaded buffer. | |
| 337 | |
| 338 | |
| 339 Upon loading a file, Vim finds the relevant syntax file as follows: | |
| 340 | |
| 341 Loading the file triggers the BufReadPost autocommands. | |
| 342 | | |
| 343 +- If there is a match with one of the autocommands from |synload-3| | |
| 344 | (known file types) or |synload-4| (user's file types), the 'filetype' | |
| 345 | option is set to the file type. | |
| 346 | | |
| 347 +- The autocommand at |synload-5| is triggered. If the file type was not | |
| 348 | found yet, then scripts.vim is searched for in 'runtimepath'. This | |
| 349 | should always load $VIMRUNTIME/scripts.vim, which does the following. | |
| 350 | | | |
| 351 | +- Source the user's optional file, from the *myscriptsfile* | |
| 352 | | variable. This is for backwards compatibility with Vim 5.x only. | |
| 353 | | | |
| 354 | +- If the file type is still unknown, check the contents of the file, | |
| 355 | again with checks like "getline(1) =~ pattern" as to whether the | |
| 356 | file type can be recognized, and set 'filetype'. | |
| 357 | | |
| 358 +- When the file type was determined and 'filetype' was set, this | |
| 359 | triggers the FileType autocommand |synload-6| above. It sets | |
| 360 | 'syntax' to the determined file type. | |
| 361 | | |
| 362 +- When the 'syntax' option was set above, this triggers an autocommand | |
| 363 | from |synload-1| (and |synload-2|). This find the main syntax file in | |
| 364 | 'runtimepath', with this command: | |
| 365 | runtime! syntax/<name>.vim | |
| 366 | | |
| 367 +- Any other user installed FileType or Syntax autocommands are | |
| 368 triggered. This can be used to change the highlighting for a specific | |
| 369 syntax. | |

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

| 407 command below, or set "g:html_start_line" and "g:html_end_line" to the first | |
| 408 and last line to be converted. Example, using the last set Visual area: > | |

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

| 454 :let g:html_whole_filler = 1 | |
| 455 < | |
| 456 *TOhtml-performance* *g:html_no_progress* | |
| 457 Default: 0. | |
| 458 When 0, display a progress bar in the statusline for each major step in the | |
| 459 2html.vim conversion process. | |
| 460 When 1, do not display the progress bar. This offers a minor speed improvement | |
| 461 but you won't have any idea how much longer the conversion might take; for big | |
| 462 files it can take a long time! | |
| 463 Example: > | |
| 464 | |
| 465 let g:html_no_progress = 1 | |
| 466 < | |
| 467 You can obtain better performance improvements by also instructing Vim to not | |
| 468 run interactively, so that too much time is not taken to redraw as the script | |
| 469 moves through the buffer, switches windows, and the like: > | |
| 470 | |
| 471 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 | |
| 472 < | |
| 473 Note that the -s flag prevents loading your .vimrc and any plugins, so you | |
| 474 need to explicitly source/enable anything that will affect the HTML | |
| 475 conversion. See |-E| and |-s-ex| for details. It is probably best to create a | |
| 476 script to replace all the -c commands and use it with the -u flag instead of | |
| 477 specifying each command separately. | |
| 478 | |
| 479 *g:html_number_lines* | |
| 480 Default: current 'number' setting. | |
| 481 When 0, buffer text is displayed in the generated HTML without line numbering. | |
| 482 When 1, a column of line numbers is added to the generated HTML with the same | |
| 483 highlighting as the line number column in Vim (|hl-LineNr|). | |
| 484 Force line numbers even if 'number' is not set: > | |
| 485 :let g:html_number_lines = 1 | |
| 486 Force to omit the line numbers: > | |
| 487 :let g:html_number_lines = 0 | |
| 488 Go back to the default to use 'number' by deleting the variable: > | |
| 489 :unlet g:html_number_lines | |
| 490 < | |

| 3713 | 508 *g:html_use_css* |
| 509 Default: 1. | |
| 510 When 1, generate valid HTML 4.01 markup with CSS1 styling, supported in all | |
| 511 modern browsers and most old browsers. | |
| 512 When 0, generate <font> tags and similar outdated markup. This is not | |
| 513 recommended but it may work better in really old browsers, email clients, | |
| 514 forum posts, and similar situations where basic CSS support is unavailable. | |
| 515 Example: > | |
| 516 :let g:html_use_css = 0 | |
| 517 < | |
| 518 *g:html_ignore_conceal* | |
| 519 Default: 0. | |
| 520 When 0, concealed text is removed from the HTML and replaced with a character | |
| 521 from |:syn-cchar| or 'listchars' as appropriate, depending on the current | |
| 522 value of 'conceallevel'. | |
| 523 When 1, include all text from the buffer in the generated HTML, even if it is | |
| 524 |conceal|ed. | |
| 525 | |
| 526 Either of the following commands will ensure that all text in the buffer is | |
| 527 included in the generated HTML (unless it is folded): > | |
| 528 :let g:html_ignore_conceal = 1 | |
| 529 :setl conceallevel=0 | |
| 530 < | |
| 531 *g:html_ignore_folding* | |
| 532 Default: 0. | |
| 533 When 0, text in a closed fold is replaced by the text shown for the fold in | |
| 534 Vim (|fold-foldtext|). See |g:html_dynamic_folds| if you also want to allow | |
| 535 the user to expand the fold as in Vim to see the text inside. | |
| 536 When 1, include all text from the buffer in the generated HTML; whether the | |
| 537 text is in a fold has no impact at all. |g:html_dynamic_folds| has no effect. | |
| 538 | |
| 539 Either of these commands will ensure that all text in the buffer is included | |
| 540 in the generated HTML (unless it is concealed): > | |
| 541 zR | |
| 542 :let g:html_ignore_folding = 1 | |
| 543 < | |
| 544 *g:html_dynamic_folds* | |
| 545 Default: 0. | |
| 546 When 0, text in a closed fold is not included at all in the generated HTML. | |
| 547 When 1, generate javascript to open a fold and show the text within, just like | |
| 548 in Vim. | |
| 549 | |
| 550 Setting this variable to 1 causes 2html.vim to always use CSS for styling, | |
| 551 regardless of what |g:html_use_css| is set to. | |
| 552 | |
| 553 This variable is ignored when |g:html_ignore_folding| is set. | |
| 554 > | |
| 555 :let g:html_dynamic_folds = 1 | |
| 556 < | |
| 557 *g:html_no_foldcolumn* | |
| 558 Default: 0. | |
| 559 When 0, if |g:html_dynamic_folds| is 1, generate a column of text similar to | |
| 560 Vim's foldcolumn (|fold-foldcolumn|) the user can click on to toggle folds | |
| 561 open or closed. The minimum width of the generated text column is the current | |
| 562 'foldcolumn' setting. | |
| 563 When 1, do not generate this column; instead, hovering the mouse cursor over | |
| 564 folded text will open the fold as if |g:html_hover_unfold| were set. | |
| 565 > | |
| 566 :let g:html_no_foldcolumn = 1 | |
| 567 < | |
| 568 *TOhtml-uncopyable-text* *g:html_prevent_copy* | |
| 569 Default: empty string. | |
| 570 This option prevents certain regions of the generated HTML from being copied, | |
| 571 when you select all text in document rendered in a browser and copy it. Useful | |
| 572 for allowing users to copy-paste only the source text even if a fold column or | |
| 573 line numbers are shown in the generated content. Specify regions to be | |
| 574 affected in this way as follows: | |
| 575 f: fold column | |
| 576 n: line numbers (also within fold text) | |
| 577 t: fold text | |
| 578 d: diff filler | |
| 579 | |
| 580 Example, to make the fold column and line numbers uncopyable: > | |
| 581 :let g:html_prevent_copy = "fn" | |
| 582 < | |
| 583 This feature is currently implemented by inserting read-only <input> elements | |
| 584 into the markup to contain the uncopyable areas. This does not work well in | |
| 585 all cases. When pasting to some applications which understand HTML, the | |
| 586 <input> elements also get pasted. But plain-text paste destinations should | |
| 587 always work. | |
| 588 | |
| 589 *g:html_no_invalid* | |
| 590 Default: 0. | |
| 591 When 0, if |g:html_prevent_copy| is non-empty, an invalid attribute is | |
| 592 intentionally inserted into the <input> element for the uncopyable areas. This | |
| 593 increases the number of applications you can paste to without also pasting the | |
| 594 <input> elements. Specifically, Microsoft Word will not paste the <input> | |
| 595 elements if they contain this invalid attribute. | |
| 596 When 1, no invalid markup is ever intentionally inserted, and the generated | |
| 597 page should validate. However, be careful pasting into Microsoft Word when | |
| 598 |g:html_prevent_copy| is non-empty; it can be hard to get rid of the <input> | |
| 599 elements which get pasted. | |
| 600 | |
| 601 *g:html_hover_unfold* | |
| 602 Default: 0. | |
| 603 When 0, the only way to open a fold generated by 2html.vim with | |
| 604 |g:html_dynamic_folds| set, is to click on the generated fold column. | |
| 605 When 1, use CSS 2.0 to allow the user to open a fold by moving the mouse | |
| 606 cursor over the displayed fold text. This is useful to allow users with | |
| 607 disabled javascript to view the folded text. | |
| 608 | |
| 609 Note that old browsers (notably Internet Explorer 6) will not support this | |
| 610 feature. Browser-specific markup for IE6 is included to fall back to the | |
| 611 normal CSS1 styling so that the folds show up correctly for this browser, but | |
| 612 they will not be openable without a foldcolumn. | |

| 3713 | 635 *TOhtml-wrap-text* *g:html_pre_wrap* |
| 636 Default: current 'wrap' setting. | |
| 637 When 0, if |g:html_no_pre| is 0 or unset, the text in the generated HTML does | |
| 638 not wrap at the edge of the browser window. | |
| 639 When 1, if |g:html_use_css| is 1, the CSS 2.0 "white-space:pre-wrap" value is | |
| 640 used, causing the text to wrap at whitespace at the edge of the browser | |
| 641 window. | |
| 642 Explicitly enable text wrapping: > | |
| 643 :let g:html_pre_wrap = 1 | |
| 644 Explicitly disable wrapping: > | |
| 645 :let g:html_pre_wrap = 0 | |

| 647 :unlet g:html_pre_wrap | |
| 648 < | |
| 649 *g:html_no_pre* | |
| 650 Default: 0. | |
| 651 When 0, buffer text in the generated HTML is surrounded by <pre>...</pre> | |
| 652 tags. Series of whitespace is shown as in Vim without special markup, and tab | |
| 653 characters can be included literally (see |g:html_expand_tabs|). | |
| 654 When 1 (not recommended), the <pre> tags are omitted, and a plain <div> is | |
| 655 used instead. Whitespace is replaced by a series of character | |
| 656 references, and <br> is used to end each line. This is another way to allow | |
| 657 text in the generated HTML is wrap (see |g:html_pre_wrap|) which also works in | |
| 658 old browsers, but may cause noticeable differences between Vim's display and | |
| 659 the rendered page generated by 2html.vim. | |
| 660 > | |
| 661 :let g:html_no_pre = 1 | |
| 662 < | |
| 663 *g:html_expand_tabs* | |
| 15033 | 664 Default: 0 if 'tabstop' is 8, 'expandtab' is 0, 'vartabstop' is not in use, |
| 665 and no fold column or line numbers occur in the generated HTML; | |
| 666 1 otherwise. | |
| 667 When 1, <Tab> characters in the buffer text are replaced with an appropriate | |
| 3713 | 668 number of space characters, or references if |g:html_no_pre| is 1. |
| 15033 | 669 When 0, if |g:html_no_pre| is 0 or unset, <Tab> characters in the buffer text |
| 3713 | 670 are included as-is in the generated HTML. This is useful for when you want to |
| 671 allow copy and paste from a browser without losing the actual whitespace in | |
| 672 the source document. Note that this can easily break text alignment and | |
| 673 indentation in the HTML, unless set by default. | |
| 674 | |
| 675 Force |2html.vim| to keep <Tab> characters: > | |
| 676 :let g:html_expand_tabs = 0 | |

| 679 :let g:html_expand_tabs = 1 | |

| 681 *TOhtml-encoding-detect* *TOhtml-encoding* | |
| 682 It is highly recommended to set your desired encoding with | |
| 683 |g:html_use_encoding| for any content which will be placed on a web server. | |
| 684 | |
| 685 If you do not specify an encoding, |2html.vim| uses the preferred IANA name | |
| 686 for the current value of 'fileencoding' if set, or 'encoding' if not. | |
| 687 'encoding' is always used for certain 'buftype' values. 'fileencoding' will be | |
| 688 set to match the chosen document encoding. | |
| 689 | |
| 690 Automatic detection works for the encodings mentioned specifically by name in | |
| 691 |encoding-names|, but TOhtml will only automatically use those encodings with | |
| 692 wide browser support. However, you can override this to support specific | |
| 693 encodings that may not be automatically detected by default (see options | |
| 694 below). See http://www.iana.org/assignments/character-sets for the IANA names. | |
| 695 | |
| 696 Note, by default all Unicode encodings are converted to UTF-8 with no BOM in | |
| 697 the generated HTML, as recommended by W3C: | |
| 698 | |
| 699 http://www.w3.org/International/questions/qa-choosing-encodings | |
| 700 http://www.w3.org/International/questions/qa-byte-order-mark | |
| 701 | |
| 702 *g:html_use_encoding* | |
| 703 Default: none, uses IANA name for current 'fileencoding' as above. | |
| 704 To overrule all automatic charset detection, set g:html_use_encoding to the | |
| 705 name of the charset to be used. It is recommended to set this variable to | |
| 706 something widely supported, like UTF-8, for anything you will be hosting on a | |
| 707 webserver: > | |
| 708 :let g:html_use_encoding = "UTF-8" | |
| 709 You can also use this option to omit the line that specifies the charset | |
| 710 entirely, by setting g:html_use_encoding to an empty string (NOT recommended): > | |
| 711 :let g:html_use_encoding = "" | |
| 712 To go back to the automatic mechanism, delete the |g:html_use_encoding| | |
| 713 variable: > | |
| 714 :unlet g:html_use_encoding | |
| 715 < | |
| 716 *g:html_encoding_override* | |
| 717 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
| 718 mentioned by name at |encoding-names|. | |
| 719 This option allows |2html.vim| to detect the correct 'fileencoding' when you | |
| 720 specify an encoding with |g:html_use_encoding| which is not in the default | |
| 721 list of conversions. | |
| 722 | |
| 723 This is a dictionary of charset-encoding pairs that will replace existing | |
| 724 pairs automatically detected by TOhtml, or supplement with new pairs. | |
| 725 | |
| 726 Detect the HTML charset "windows-1252" as the encoding "8bit-cp1252": > | |
| 727 :let g:html_encoding_override = {'windows-1252': '8bit-cp1252'} | |
| 728 < | |
| 729 *g:html_charset_override* | |
| 730 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
| 731 mentioned by name at |encoding-names| and which have wide | |
| 732 browser support. | |
| 733 This option allows |2html.vim| to detect the HTML charset for any | |
| 734 'fileencoding' or 'encoding' which is not detected automatically. You can also | |
| 735 use it to override specific existing encoding-charset pairs. For example, | |
| 736 TOhtml will by default use UTF-8 for all Unicode/UCS encodings. To use UTF-16 | |
| 737 and UTF-32 instead, use: > | |
| 738 :let g:html_charset_override = {'ucs-4': 'UTF-32', 'utf-16': 'UTF-16'} | |
| 739 | |
| 740 Note that documents encoded in either UTF-32 or UTF-16 have known | |
| 741 compatibility problems with some major browsers. | |

| 827 startup vimrc: > | |
| 828 :let filetype_i = "asm" | |
| 829 Replace "asm" with the type of assembly you use. | |
| 830 | |
| 831 There are many types of assembly languages that all use the same file name | |
| 832 extensions. Therefore you will have to select the type yourself, or add a | |
| 833 line in the assembly file that Vim will recognize. Currently these syntax | |
| 834 files are included: | |
| 835 asm GNU assembly (the default) | |
| 836 asm68k Motorola 680x0 assembly | |
| 837 asmh8300 Hitachi H-8300 version of GNU assembly | |
| 838 ia64 Intel Itanium 64 | |
| 839 fasm Flat assembly (http://flatassembler.net) | |
| 840 masm Microsoft assembly (probably works for any 80x86) | |
| 841 nasm Netwide assembly | |
| 842 tasm Turbo Assembly (with opcodes 80x86 up to Pentium, and | |
| 843 MMX) | |
| 844 pic PIC assembly (currently for PIC16F84) | |
| 845 | |
| 846 The most flexible is to add a line in your assembly file containing: > | |

849 one of the first five lines in the file. No non-white text must be |
| 3682 | 850 immediately before or after this text. Note that specifying asmsyntax=foo is |
| 851 equivalent to setting ft=foo in a |modeline|, and that in case of a conflict | |
| 852 between the two settings the one from the modeline will take precedence (in | |
| 853 particular, if you have ft=asm in the modeline, you will get the GNU syntax | |
| 854 highlighting regardless of what is specified as asmsyntax). | |
| 7 | 855 |
| 856 The syntax type can always be overruled for a specific buffer by setting the | |
| 857 b:asmsyntax variable: > | |
| 1624 | 858 :let b:asmsyntax = "nasm" |
| 7 | 859 |
| 860 If b:asmsyntax is not set, either automatically or by hand, then the value of | |
| 861 the global variable asmsyntax is used. This can be seen as a default assembly | |
| 862 language: > | |
| 1624 | 863 :let asmsyntax = "nasm" |
| 7 | 864 |
| 865 As a last resort, if nothing is defined, the "asm" syntax is used. | |

| 501 | 882 ASPPERL and ASPVBS *ft-aspperl-syntax* *ft-aspvbs-syntax* |
| 7 | 883 |
| 884 *.asp and *.asa files could be either Perl or Visual Basic script. Since it's | |
| 885 hard to detect this you can set two global variables to tell Vim what you are | |
| 886 using. For Perl script use: > | |
| 887 :let g:filetype_asa = "aspperl" | |
| 888 :let g:filetype_asp = "aspperl" | |
| 889 For Visual Basic use: > | |
| 890 :let g:filetype_asa = "aspvbs" | |
| 891 :let g:filetype_asp = "aspvbs" | |

| 893 | |
| 856 | 894 BAAN *baan.vim* *baan-syntax* |
| 844 | 895 |
| 896 The baan.vim gives syntax support for BaanC of release BaanIV upto SSA ERP LN | |
| 897 for both 3 GL and 4 GL programming. Large number of standard defines/constants | |
| 898 are supported. | |
| 899 | |
| 900 Some special violation of coding standards will be signalled when one specify | |
| 901 in ones |.vimrc|: > | |
| 902 let baan_code_stds=1 | |
| 903 | |
| 904 *baan-folding* | |
| 905 | |
| 906 Syntax folding can be enabled at various levels through the variables | |
| 907 mentioned below (Set those in your |.vimrc|). The more complex folding on | |
| 908 source blocks and SQL can be CPU intensive. | |
| 909 | |
| 910 To allow any folding and enable folding at function level use: > | |
| 911 let baan_fold=1 | |
| 912 Folding can be enabled at source block level as if, while, for ,... The | |
| 913 indentation preceding the begin/end keywords has to match (spaces are not | |
| 914 considered equal to a tab). > | |
| 915 let baan_fold_block=1 | |
| 916 Folding can be enabled for embedded SQL blocks as SELECT, SELECTDO, | |
| 856 | 917 SELECTEMPTY, ... The indentation preceding the begin/end keywords has to |
| 844 | 918 match (spaces are not considered equal to a tab). > |
| 919 let baan_fold_sql=1 | |
| 856 | 920 Note: Block folding can result in many small folds. It is suggested to |:set| |
| 844 | 921 the options 'foldminlines' and 'foldnestmax' in |.vimrc| or use |:setlocal| in |
| 922 .../after/syntax/baan.vim (see |after-directory|). Eg: > | |
| 923 set foldminlines=5 | |
| 924 set foldnestmax=6 | |
| 925 | |
| 926 | |
| 501 | 927 BASIC *basic.vim* *vb.vim* *ft-basic-syntax* *ft-vb-syntax* |
| 7 | 928 |
| 929 Both Visual Basic and "normal" basic use the extension ".bas". To detect | |
| 930 which one should be used, Vim checks for the string "VB_Name" in the first | |
| 931 five lines of the file. If it is not found, filetype will be "basic", | |
| 932 otherwise "vb". Files with the ".frm" extension will always be seen as Visual | |
| 933 Basic. | |
| 934 | |
| 935 | |
| 501 | 936 C *c.vim* *ft-c-syntax* |
| 7 | 937 |
| 938 A few things in C highlighting are optional. To enable them assign any value | |
| 939 to the respective variable. Example: > | |
| 1624 | 940 :let c_comment_strings = 1 |
| 7 | 941 To disable them use ":unlet". Example: > |
| 942 :unlet c_comment_strings | |
| 943 | |
| 14999 | 944 An alternative is to switch to the C++ highlighting: > |
| 945 :set filetype=cpp | |

970 *c_no_bsd* don't highlight BSD specific types |
| 7 | 971 |
| 36 | 972 When 'foldmethod' is set to "syntax" then /* */ comments and { } blocks will |
| 973 become a fold. If you don't want comments to become a fold use: > | |
| 974 :let c_no_comment_fold = 1 | |
| 842 | 975 "#if 0" blocks are also folded, unless: > |
| 976 :let c_no_if0_fold = 1 | |
| 36 | 977 |
| 7 | 978 If you notice highlighting errors while scrolling backwards, which are fixed |
| 979 when redrawing with CTRL-L, try setting the "c_minlines" internal variable | |
| 980 to a larger number: > | |
| 981 :let c_minlines = 100 | |
| 982 This will make the syntax synchronization start 100 lines before the first | |
| 983 displayed line. The default value is 50 (15 when c_no_if0 is set). The | |
| 984 disadvantage of using a larger number is that redrawing can become slow. | |
| 985 | |
| 986 When using the "#if 0" / "#endif" comment highlighting, notice that this only | |
| 987 works when the "#if 0" is within "c_minlines" from the top of the window. If | |
| 988 you have a long "#if 0" construct it will not be highlighted correctly. | |
| 989 | |
| 990 To match extra items in comments, use the cCommentGroup cluster. | |
| 991 Example: > | |
| 992 :au Syntax c call MyCadd() | |
| 993 :function MyCadd() | |
| 994 : syn keyword cMyItem contained Ni | |
| 995 : syn cluster cCommentGroup add=cMyItem | |
| 996 : hi link cMyItem Title | |
| 997 :endfun | |
| 998 | |
| 999 ANSI constants will be highlighted with the "cConstant" group. This includes | |
| 1000 "NULL", "SIG_IGN" and others. But not "TRUE", for example, because this is | |
| 1001 not in the ANSI standard. If you find this confusing, remove the cConstant | |
| 1002 highlighting: > | |
| 1003 :hi link cConstant NONE | |
| 1004 | |
| 1005 If you see '{' and '}' highlighted as an error where they are OK, reset the | |
| 1006 highlighting for cErrInParen and cErrInBracket. | |
| 1007 | |
| 1008 If you want to use folding in your C files, you can add these lines in a file | |

| 1016 C/C++ interpreter. Ch has similar syntax highlighting to C and builds upon | |
| 1017 the C syntax file. See |c.vim| for all the settings that are available for C. | |
| 1018 | |
| 1019 By setting a variable you can tell Vim to use Ch syntax for *.h files, instead | |
| 1020 of C or C++: > | |
| 1021 :let ch_syntax_for_h = 1 | |
| 1022 | |
| 7 | 1023 |
| 501 | 1024 CHILL *chill.vim* *ft-chill-syntax* |
| 7 | 1025 |
| 1026 Chill syntax highlighting is similar to C. See |c.vim| for all the settings | |
| 1027 that are available. Additionally there is: | |
| 1028 | |
| 1029 chill_space_errors like c_space_errors | |
| 1030 chill_comment_string like c_comment_strings | |
| 1031 chill_minlines like c_minlines | |
| 1032 | |
| 1033 | |
| 501 | 1034 CHANGELOG *changelog.vim* *ft-changelog-syntax* |
| 7 | 1035 |
| 1036 ChangeLog supports highlighting spaces at the start of a line. | |
| 1037 If you do not like this, add following line to your .vimrc: > | |
| 1038 let g:changelog_spacing_errors = 0 | |
| 1039 This works the next time you edit a changelog file. You can also use | |
| 1040 "b:changelog_spacing_errors" to set this per buffer (before loading the syntax | |
| 1041 file). | |
| 1042 | |
| 1043 You can change the highlighting used, e.g., to flag the spaces as an error: > | |
| 1044 :hi link ChangelogError Error | |
| 1045 Or to avoid the highlighting: > | |
| 1046 :hi link ChangelogError NONE | |
| 1047 This works immediately. | |

| 1082 COBOL highlighting has different needs for legacy code than it does for fresh | |
| 1083 development. This is due to differences in what is being done (maintenance | |
| 1084 versus development) and other factors. To enable legacy code highlighting, | |
| 1085 add this line to your .vimrc: > | |
| 1086 :let cobol_legacy_code = 1 | |
| 1087 To disable it again, use this: > | |

1107 cpp_no_cpp14 don't highlight C++14 standard items |

| 501 | 1110 CSH *csh.vim* *ft-csh-syntax* |
| 7 | 1111 |
| 1112 This covers the shell named "csh". Note that on some systems tcsh is actually | |
| 1113 used. | |
| 1114 | |
| 1115 Detecting whether a file is csh or tcsh is notoriously hard. Some systems | |
| 1116 symlink /bin/csh to /bin/tcsh, making it almost impossible to distinguish | |
| 1117 between csh and tcsh. In case VIM guesses wrong you can set the | |
| 2965 | 1118 "filetype_csh" variable. For using csh: *g:filetype_csh* |
| 1119 > | |
| 1120 :let g:filetype_csh = "csh" | |
| 7 | 1121 |
| 1122 For using tcsh: > | |
| 1123 | |
| 2965 | 1124 :let g:filetype_csh = "tcsh" |
| 7 | 1125 |
| 1126 Any script with a tcsh extension or a standard tcsh filename (.tcshrc, | |
| 1127 tcsh.tcshrc, tcsh.login) will have filetype tcsh. All other tcsh/csh scripts | |
| 237 | 1128 will be classified as tcsh, UNLESS the "filetype_csh" variable exists. If the |
| 7 | 1129 "filetype_csh" variable exists, the filetype will be set to the value of the |
| 1130 variable. | |
| 1131 | |
| 1132 | |
| 501 | 1133 CYNLIB *cynlib.vim* *ft-cynlib-syntax* |
| 7 | 1134 |
| 1135 Cynlib files are C++ files that use the Cynlib class library to enable | |
| 237 | 1136 hardware modelling and simulation using C++. Typically Cynlib files have a .cc |
| 7 | 1137 or a .cpp extension, which makes it very difficult to distinguish them from a |
| 237 | 1138 normal C++ file. Thus, to enable Cynlib highlighting for .cc files, add this |
| 7 | 1139 line to your .vimrc file: > |
| 1140 | |
| 1141 :let cynlib_cyntax_for_cc=1 | |
| 1142 | |
| 1143 Similarly for cpp files (this extension is only usually used in Windows) > | |
| 1144 | |
| 1145 :let cynlib_cyntax_for_cpp=1 | |
| 1146 | |
| 1147 To disable these again, use this: > | |
| 1148 | |
| 1149 :unlet cynlib_cyntax_for_cc | |
| 1150 :unlet cynlib_cyntax_for_cpp | |
| 1151 < | |
| 1152 | |
| 501 | 1153 CWEB *cweb.vim* *ft-cweb-syntax* |
| 7 | 1154 |
| 1155 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
| 1156 doesn't work for you, or you don't edit Progress at all, use this in your | |
| 1157 startup vimrc: > | |
| 1158 :let filetype_w = "cweb" | |
| 1159 | |
| 1160 | |
| 18456 | 1161 DART *dart.vim* *ft-dart-syntax* |
| 1162 | |
| 1163 Dart is an object-oriented, typed, class defined, garbage collected language | |
| 1164 used for developing mobile, desktop, web, and back-end applications. Dart uses | |
| 1165 a C-like syntax derived from C, Java, and JavaScript, with features adopted | |
| 1166 from Smalltalk, Python, Ruby, and others. | |
| 1167 | |
| 1168 More information about the language and its development environment at the | |
| 1169 official Dart language website at https://dart.dev | |
| 1170 | |
| 1171 dart.vim syntax detects and highlights Dart statements, reserved words, | |
| 1172 type declarations, storage classes, conditionals, loops, interpolated values, | |
| 1173 and comments. There is no support idioms from Flutter or any other Dart | |
| 1174 framework. | |

| 7 | 1186 But actually almost none implements this standard fully. Thus it will |
| 237 | 1187 highlight all Unix ini files. But you can force strict highlighting according |

| 1193 | |
| 1194 The diff highlighting normally finds translated headers. This can be slow if | |

| 501 | 1202 DIRCOLORS *dircolors.vim* *ft-dircolors-syntax* |
| 7 | 1203 |
| 1204 The dircolors utility highlighting definition has one option. It exists to | |
| 1205 provide compatibility with the Slackware GNU/Linux distributions version of | |
| 1206 the command. It adds a few keywords that are generally ignored by most | |
| 1207 versions. On Slackware systems, however, the utility accepts the keywords and | |
| 1208 uses them for processing. To enable the Slackware keywords add the following | |
| 1209 line to your startup file: > | |
| 1210 let dircolors_is_slackware = 1 | |
| 1211 | |
| 1212 | |
| 501 | 1213 DOCBOOK *docbk.vim* *ft-docbk-syntax* *docbook* |
| 2662 | 1214 DOCBOOK XML *docbkxml.vim* *ft-docbkxml-syntax* |
| 1215 DOCBOOK SGML *docbksgml.vim* *ft-docbksgml-syntax* | |
| 7 | 1216 |
| 1217 There are two types of DocBook files: SGML and XML. To specify what type you | |
| 1218 are using the "b:docbk_type" variable should be set. Vim does this for you | |
| 1219 automatically if it can recognize the type. When Vim can't guess it the type | |
| 1220 defaults to XML. | |
| 1221 You can set the type manually: > | |
| 1222 :let docbk_type = "sgml" | |
| 1223 or: > | |
| 1224 :let docbk_type = "xml" | |
| 1225 You need to do this before loading the syntax file, which is complicated. | |
| 1226 Simpler is setting the filetype to "docbkxml" or "docbksgml": > | |
| 1227 :set filetype=docbksgml | |
| 1228 or: > | |
| 1229 :set filetype=docbkxml | |
| 1230 | |
| 3967 | 1231 You can specify the DocBook version: > |
| 1232 :let docbk_ver = 3 | |
| 1233 When not set 4 is used. | |
| 1234 | |
| 7 | 1235 |
| 501 | 1236 DOSBATCH *dosbatch.vim* *ft-dosbatch-syntax* |
| 7 | 1237 |
| 1238 There is one option with highlighting DOS batch files. This covers new | |
| 1239 extensions to the Command Interpreter introduced with Windows 2000 and | |
| 1240 is controlled by the variable dosbatch_cmdextversion. For Windows NT | |
| 1241 this should have the value 1, and for Windows 2000 it should be 2. | |
| 1242 Select the version you want with the following line: > | |
| 1243 | |
| 15 | 1244 :let dosbatch_cmdextversion = 1 |
| 7 | 1245 |
| 1246 If this variable is not defined it defaults to a value of 2 to support | |
| 1247 Windows 2000. | |
| 1248 | |
| 15 | 1249 A second option covers whether *.btm files should be detected as type |
| 237 | 1250 "dosbatch" (MS-DOS batch files) or type "btm" (4DOS batch files). The latter |
| 1251 is used by default. You may select the former with the following line: > | |
| 15 | 1252 |
| 1253 :let g:dosbatch_syntax_for_btm = 1 | |
| 1254 | |
| 1255 If this variable is undefined or zero, btm syntax is selected. | |
| 1256 | |
| 1257 | |
| 832 | 1258 DOXYGEN *doxygen.vim* *doxygen-syntax* |
| 1259 | |
| 1260 Doxygen generates code documentation using a special documentation format | |
| 1698 | 1261 (similar to Javadoc). This syntax script adds doxygen highlighting to c, cpp, |
| 1262 idl and php files, and should also work with java. | |
| 832 | 1263 |
| 1224 | 1264 There are a few of ways to turn on doxygen formatting. It can be done |
| 1265 explicitly or in a modeline by appending '.doxygen' to the syntax of the file. | |
| 1266 Example: > | |
| 832 | 1267 :set syntax=c.doxygen |
| 1268 or > | |
| 1269 // vim:syntax=c.doxygen | |
| 1270 | |
| 3356 | 1271 It can also be done automatically for C, C++, C#, IDL and PHP files by setting |
| 1272 the global or buffer-local variable load_doxygen_syntax. This is done by | |
| 1273 adding the following to your .vimrc. > | |
| 832 | 1274 :let g:load_doxygen_syntax=1 |

1276 There are a couple of variables that have an effect on syntax highlighting, and |
| 832 | 1277 are to do with non-standard highlighting options. |
| 1278 | |
| 1279 Variable Default Effect ~ | |
| 1280 g:doxygen_enhanced_color | |
| 1281 g:doxygen_enhanced_colour 0 Use non-standard highlighting for | |
| 1282 doxygen comments. | |
| 1283 | |
| 1284 doxygen_my_rendering 0 Disable rendering of HTML bold, italic | |
| 1285 and html_my_rendering underline. | |
| 1286 | |
| 1287 doxygen_javadoc_autobrief 1 Set to 0 to disable javadoc autobrief | |
| 1288 colour highlighting. | |
| 1289 | |
| 1290 doxygen_end_punctuation '[.]' Set to regexp match for the ending | |
| 856 | 1291 punctuation of brief |
| 832 | 1292 |
| 14637 | 1293 There are also some highlight groups worth mentioning as they can be useful in |
| 832 | 1294 configuration. |
| 1295 | |
| 1296 Highlight Effect ~ | |
| 1297 doxygenErrorComment The colour of an end-comment when missing | |
| 1298 punctuation in a code, verbatim or dot section | |
| 1299 doxygenLinkError The colour of an end-comment when missing the | |
| 1300 \endlink from a \link section. | |
| 1301 | |
| 7 | 1302 |
| 501 | 1303 DTD *dtd.vim* *ft-dtd-syntax* |
| 7 | 1304 |
| 237 | 1305 The DTD syntax highlighting is case sensitive by default. To disable |
| 7 | 1306 case-sensitive highlighting, add the following line to your startup file: > |
| 1307 | |
| 1308 :let dtd_ignore_case=1 | |
| 1309 | |
| 237 | 1310 The DTD syntax file will highlight unknown tags as errors. If |
| 7 | 1311 this is annoying, it can be turned off by setting: > |
| 1312 | |
| 1313 :let dtd_no_tag_errors=1 | |
| 1314 | |
| 1315 before sourcing the dtd.vim syntax file. | |
| 1316 Parameter entity names are highlighted in the definition using the | |
| 1317 'Type' highlighting group and 'Comment' for punctuation and '%'. | |
| 1318 Parameter entity instances are highlighted using the 'Constant' | |
| 1319 highlighting group and the 'Type' highlighting group for the | |
| 237 | 1320 delimiters % and ;. This can be turned off by setting: > |
| 7 | 1321 |
| 1322 :let dtd_no_param_entities=1 | |
| 1323 | |
| 1324 The DTD syntax file is also included by xml.vim to highlight included dtd's. | |
| 1325 | |
| 1326 | |
| 501 | 1327 EIFFEL *eiffel.vim* *ft-eiffel-syntax* |
| 7 | 1328 |
| 1329 While Eiffel is not case-sensitive, its style guidelines are, and the | |
| 237 | 1330 syntax highlighting file encourages their use. This also allows to |
| 1331 highlight class names differently. If you want to disable case-sensitive | |
| 7 | 1332 highlighting, add the following line to your startup file: > |
| 1333 | |
| 1334 :let eiffel_ignore_case=1 | |
| 1335 | |
| 1336 Case still matters for class names and TODO marks in comments. | |
| 1337 | |
| 1338 Conversely, for even stricter checks, add one of the following lines: > | |
| 1339 | |
| 1340 :let eiffel_strict=1 | |
| 1341 :let eiffel_pedantic=1 | |
| 1342 | |
| 1343 Setting eiffel_strict will only catch improper capitalization for the | |
| 1344 five predefined words "Current", "Void", "Result", "Precursor", and | |
| 1345 "NONE", to warn against their accidental use as feature or class names. | |
| 1346 | |
| 1347 Setting eiffel_pedantic will enforce adherence to the Eiffel style | |
| 1348 guidelines fairly rigorously (like arbitrary mixes of upper- and | |
| 1349 lowercase letters as well as outdated ways to capitalize keywords). | |
| 1350 | |
| 1351 If you want to use the lower-case version of "Current", "Void", | |
| 1352 "Result", and "Precursor", you can use > | |
| 1353 | |
| 1354 :let eiffel_lower_case_predef=1 | |
| 1355 | |
| 1356 instead of completely turning case-sensitive highlighting off. | |
| 1357 | |
| 1358 Support for ISE's proposed new creation syntax that is already | |
| 1359 experimentally handled by some compilers can be enabled by: > | |
| 1360 | |
| 1361 :let eiffel_ise=1 | |
| 1362 | |
| 237 | 1363 Finally, some vendors support hexadecimal constants. To handle them, add > |
| 7 | 1364 |
| 1365 :let eiffel_hex_constants=1 | |
| 1366 | |
| 1367 to your startup file. | |
| 1368 | |
| 1369 | |
| 5697 | 1370 EUPHORIA *euphoria3.vim* *euphoria4.vim* *ft-euphoria-syntax* |
| 1371 | |
| 1372 Two syntax highlighting files exists for Euphoria. One for Euphoria | |
| 1373 version 3.1.1, which is the default syntax highlighting file, and one for | |
| 1374 Euphoria version 4.0.5 or later. | |
| 1375 | |
| 1376 Euphoria version 3.1.1 (http://www.rapideuphoria.com/) is still necessary | |
| 1377 for developing applications for the DOS platform, which Euphoria version 4 | |
| 1378 (http://www.openeuphoria.org/) does not support. | |
| 1379 | |
| 1380 The following file extensions are auto-detected as Euphoria file type: | |
| 1381 | |
| 1382 *.e, *.eu, *.ew, *.ex, *.exu, *.exw | |
| 1383 *.E, *.EU, *.EW, *.EX, *.EXU, *.EXW | |
| 1384 | |
| 1385 To select syntax highlighting file for Euphoria, as well as for | |
| 1386 auto-detecting the *.e and *.E file extensions as Euphoria file type, | |
| 1387 add the following line to your startup file: > | |
| 1388 | |
| 1389 :let filetype_euphoria="euphoria3" | |
| 1390 | |
| 1391 or | |

| 857 | 1411 FLEXWIKI *flexwiki.vim* *ft-flexwiki-syntax* |
| 1412 | |
| 1413 FlexWiki is an ASP.NET-based wiki package available at http://www.flexwiki.com | |
| 2826 | 1414 NOTE: this site currently doesn't work, on Wikipedia is mentioned that |
| 1415 development stopped in 2009. | |
| 857 | 1416 |
| 1417 Syntax highlighting is available for the most common elements of FlexWiki | |
| 1418 syntax. The associated ftplugin script sets some buffer-local options to make | |
| 1419 editing FlexWiki pages more convenient. FlexWiki considers a newline as the | |
| 1420 start of a new paragraph, so the ftplugin sets 'tw'=0 (unlimited line length), | |
| 1421 'wrap' (wrap long lines instead of using horizontal scrolling), 'linebreak' | |
| 1422 (to wrap at a character in 'breakat' instead of at the last char on screen), | |
| 1423 and so on. It also includes some keymaps that are disabled by default. | |
| 1424 | |
| 1425 If you want to enable the keymaps that make "j" and "k" and the cursor keys | |
| 1426 move up and down by display lines, add this to your .vimrc: > | |
| 1427 :let flexwiki_maps = 1 | |
| 1428 | |
| 1429 | |
| 501 | 1430 FORM *form.vim* *ft-form-syntax* |
| 7 | 1431 |
| 1432 The coloring scheme for syntax elements in the FORM file uses the default | |
| 1433 modes Conditional, Number, Statement, Comment, PreProc, Type, and String, | |
| 1275 | 1434 following the language specifications in 'Symbolic Manipulation with FORM' by |
| 7 | 1435 J.A.M. Vermaseren, CAN, Netherlands, 1991. |
| 1436 | |
| 1437 If you want include your own changes to the default colors, you have to | |
| 1438 redefine the following syntax groups: | |
| 1439 | |
| 1440 - formConditional | |
| 1441 - formNumber | |
| 1442 - formStatement | |
| 1443 - formHeaderStatement | |
| 1444 - formComment | |
| 1445 - formPreProc | |
| 1446 - formDirective | |
| 1447 - formType | |
| 1448 - formString | |
| 1449 | |
| 1450 Note that the form.vim syntax file implements FORM preprocessor commands and | |
| 1451 directives per default in the same syntax group. | |
| 1452 | |
| 1453 A predefined enhanced color mode for FORM is available to distinguish between | |
| 237 | 1454 header statements and statements in the body of a FORM program. To activate |
| 7 | 1455 this mode define the following variable in your vimrc file > |
| 1456 | |
| 1457 :let form_enhanced_color=1 | |
| 1458 | |
| 1459 The enhanced mode also takes advantage of additional color features for a dark | |
| 237 | 1460 gvim display. Here, statements are colored LightYellow instead of Yellow, and |
| 7 | 1461 conditionals are LightBlue for better distinction. |
| 1462 | |
| 1463 | |
| 501 | 1464 FORTRAN *fortran.vim* *ft-fortran-syntax* |
| 7 | 1465 |
| 1466 Default highlighting and dialect ~ | |
| 3256 | 1467 Highlighting appropriate for Fortran 2008 is used by default. This choice |
| 4992 | 1468 should be appropriate for most users most of the time because Fortran 2008 is |
| 1469 almost a superset of previous versions (Fortran 2003, 95, 90, and 77). | |
| 7 | 1470 |
| 1471 Fortran source code form ~ | |
| 3281 | 1472 Fortran code can be in either fixed or free source form. Note that the |
| 7 | 1473 syntax highlighting will not be correct if the form is incorrectly set. |
| 1474 | |
| 1475 When you create a new fortran file, the syntax script assumes fixed source | |
| 237 | 1476 form. If you always use free source form, then > |
| 7 | 1477 :let fortran_free_source=1 |
| 237 | 1478 in your .vimrc prior to the :syntax on command. If you always use fixed source |
| 7 | 1479 form, then > |
| 1480 :let fortran_fixed_source=1 | |
| 1481 in your .vimrc prior to the :syntax on command. | |

1503 of the first twenty-five lines, save (:w) and then reload (:e!) the file. |
| 7 | 1504 |
| 1505 Tabs in fortran files ~ | |
| 237 | 1506 Tabs are not recognized by the Fortran standards. Tabs are not a good idea in |
| 7 | 1507 fixed format fortran source code which requires fixed column boundaries. |
| 237 | 1508 Therefore, tabs are marked as errors. Nevertheless, some programmers like |
| 1509 using tabs. If your fortran files contain tabs, then you should set the | |
| 7 | 1510 variable fortran_have_tabs in your .vimrc with a command such as > |
| 1511 :let fortran_have_tabs=1 | |
| 237 | 1512 placed prior to the :syntax on command. Unfortunately, the use of tabs will |
| 7 | 1513 mean that the syntax file will not be able to detect incorrect margins. |
| 1514 | |
| 1515 Syntax folding of fortran files ~ | |
| 1516 If you wish to use foldmethod=syntax, then you must first set the variable | |
| 1517 fortran_fold with a command such as > | |
| 1518 :let fortran_fold=1 | |
| 1519 to instruct the syntax script to define fold regions for program units, that | |
| 1520 is main programs starting with a program statement, subroutines, function | |
| 237 | 1521 subprograms, block data subprograms, interface blocks, and modules. If you |
| 7 | 1522 also set the variable fortran_fold_conditionals with a command such as > |
| 1523 :let fortran_fold_conditionals=1 | |
| 1524 then fold regions will also be defined for do loops, if blocks, and select | |
| 237 | 1525 case constructs. If you also set the variable |
| 7 | 1526 fortran_fold_multilinecomments with a command such as > |
| 1527 :let fortran_fold_multilinecomments=1 | |
| 1528 then fold regions will also be defined for three or more consecutive comment | |
| 237 | 1529 lines. Note that defining fold regions can be slow for large files. |
| 7 | 1530 |
| 1531 If fortran_fold, and possibly fortran_fold_conditionals and/or | |
| 1532 fortran_fold_multilinecomments, have been set, then vim will fold your file if | |
| 237 | 1533 you set foldmethod=syntax. Comments or blank lines placed between two program |
| 7 | 1534 units are not folded because they are seen as not belonging to any program |
| 1535 unit. | |
| 1536 | |
| 1537 More precise fortran syntax ~ | |
| 1538 If you set the variable fortran_more_precise with a command such as > | |
| 1539 :let fortran_more_precise=1 | |
| 237 | 1540 then the syntax coloring will be more precise but slower. In particular, |
| 7 | 1541 statement labels used in do, goto and arithmetic if statements will be |
| 1542 recognized, as will construct names at the end of a do, if, select or forall | |
| 1543 construct. | |
| 1544 | |
| 1545 Non-default fortran dialects ~ | |
| 3281 | 1546 The syntax script supports two Fortran dialects: f08 and F. You will probably |
| 1547 find the default highlighting (f08) satisfactory. A few legacy constructs | |
| 1548 deleted or declared obsolescent in the 2008 standard are highlighted as todo | |
| 1549 items. | |
| 1550 | |
| 1551 If you use F, the advantage of setting the dialect appropriately is that | |
| 1552 other legacy features excluded from F will be highlighted as todo items and | |
| 4992 | 1553 that free source form will be assumed. |
| 3281 | 1554 |
| 1555 The dialect can be selected in various ways. If all your fortran files use | |
| 1556 the same dialect, set the global variable fortran_dialect in your .vimrc prior | |
| 1557 to your syntax on statement. The case-sensitive, permissible values of | |
| 1558 fortran_dialect are "f08" or "F". Invalid values of fortran_dialect are | |
| 1559 ignored. | |
| 1560 | |
| 1561 If the dialect depends upon the file extension, then it is most convenient to | |
| 1562 set a buffer-local variable in a ftplugin file. For more information on | |
| 1563 ftplugin files, see |ftplugin|. For example, if all your fortran files with | |
| 1564 an .f90 extension are written in the F subset, your ftplugin file should | |
| 1565 contain the code > | |
| 7 | 1566 let s:extfname = expand("%:e") |
| 1567 if s:extfname ==? "f90" | |
| 3281 | 1568 let b:fortran_dialect="F" |
| 7 | 1569 else |
| 3281 | 1570 unlet! b:fortran_dialect |
| 7 | 1571 endif |
| 1572 Note that this will work only if the "filetype plugin indent on" command | |
| 1573 precedes the "syntax on" command in your .vimrc file. | |
| 1574 | |
| 1575 Finer control is necessary if the file extension does not uniquely identify | |
| 3281 | 1576 the dialect. You can override the default dialect, on a file-by-file basis, |
| 1577 by including a comment with the directive "fortran_dialect=xx" (where xx=F or | |
| 1578 f08) in one of the first three lines in your file. For example, your older .f | |
| 1579 files may be legacy code but your newer ones may be F codes, and you would | |
| 1580 identify the latter by including in the first three lines of those files a | |
| 1581 Fortran comment of the form > | |
| 7 | 1582 ! fortran_dialect=F |
| 3281 | 1583 |
| 1584 For previous versions of the syntax, you may have set fortran_dialect to the | |
| 1585 now-obsolete values "f77", "f90", "f95", or "elf". Such settings will be | |
| 1586 silently handled as "f08". Users of "elf" may wish to experiment with "F" | |
| 4992 | 1587 instead. |
| 3281 | 1588 |
| 1589 The syntax/fortran.vim script contains embedded comments that tell you how to | |
| 1590 comment and/or uncomment some lines to (a) activate recognition of some | |
| 1591 non-standard, vendor-supplied intrinsics and (b) to prevent features deleted | |
| 1592 or declared obsolescent in the 2008 standard from being highlighted as todo | |
| 4992 | 1593 items. |
| 7 | 1594 |
| 1595 Limitations ~ | |
| 237 | 1596 Parenthesis checking does not catch too few closing parentheses. Hollerith |
| 1597 strings are not recognized. Some keywords may be highlighted incorrectly | |
| 7 | 1598 because Fortran90 has no reserved words. |
| 1599 | |
| 501 | 1600 For further information related to fortran, see |ft-fortran-indent| and |
| 1601 |ft-fortran-plugin|. | |
| 1602 | |
| 1603 | |
| 1604 FVWM CONFIGURATION FILES *fvwm.vim* *ft-fvwm-syntax* | |
| 7 | 1605 |
| 1606 In order for Vim to recognize Fvwm configuration files that do not match | |
| 1607 the patterns *fvwmrc* or *fvwm2rc* , you must put additional patterns | |
| 1608 appropriate to your system in your myfiletypes.vim file. For these | |
| 1609 patterns, you must set the variable "b:fvwm_version" to the major version | |
| 1610 number of Fvwm, and the 'filetype' option to fvwm. | |
| 1611 | |
| 1612 For example, to make Vim identify all files in /etc/X11/fvwm2/ | |
| 1613 as Fvwm2 configuration files, add the following: > | |
| 1614 | |
| 1615 :au! BufNewFile,BufRead /etc/X11/fvwm2/* let b:fvwm_version = 2 | | |
| 1616 \ set filetype=fvwm | |
| 1617 | |
| 1618 If you'd like Vim to highlight all valid color names, tell it where to | |
| 1619 find the color database (rgb.txt) on your system. Do this by setting | |
| 1620 "rgb_file" to its location. Assuming your color database is located | |
| 1621 in /usr/X11/lib/X11/, you should add the line > | |
| 1622 | |
| 1623 :let rgb_file = "/usr/X11/lib/X11/rgb.txt" | |
| 1624 | |
| 1625 to your .vimrc file. | |
| 1626 | |
| 1627 | |
| 501 | 1628 GSP *gsp.vim* *ft-gsp-syntax* |
| 7 | 1629 |
| 1630 The default coloring style for GSP pages is defined by |html.vim|, and | |
| 1631 the coloring for java code (within java tags or inline between backticks) | |
| 1632 is defined by |java.vim|. The following HTML groups defined in |html.vim| | |
| 1633 are redefined to incorporate and highlight inline java code: | |
| 1634 | |
| 1635 htmlString | |
| 1636 htmlValue | |
| 1637 htmlEndTag | |
| 1638 htmlTag | |
| 1639 htmlTagN | |
| 1640 | |
| 1641 Highlighting should look fine most of the places where you'd see inline | |
| 1642 java code, but in some special cases it may not. To add another HTML | |
| 1643 group where you will have inline java code where it does not highlight | |
| 1644 correctly, just copy the line you want from |html.vim| and add gspJava | |
| 1645 to the contains clause. | |
| 1646 | |
| 1647 The backticks for inline java are highlighted according to the htmlError | |
| 1648 group to make them easier to see. | |
| 1649 | |
| 1650 | |
| 501 | 1651 GROFF *groff.vim* *ft-groff-syntax* |
| 7 | 1652 |
| 1653 The groff syntax file is a wrapper for |nroff.vim|, see the notes | |
| 237 | 1654 under that heading for examples of use and configuration. The purpose |
| 7 | 1655 of this wrapper is to set up groff syntax extensions by setting the |
| 1656 filetype from a |modeline| or in a personal filetype definitions file | |
| 1657 (see |filetype.txt|). | |
| 1658 | |
| 1659 | |
| 501 | 1660 HASKELL *haskell.vim* *lhaskell.vim* *ft-haskell-syntax* |
| 7 | 1661 |
| 1662 The Haskell syntax files support plain Haskell code as well as literate | |
| 237 | 1663 Haskell code, the latter in both Bird style and TeX style. The Haskell |
| 7 | 1664 syntax highlighting will also highlight C preprocessor directives. |
| 1665 | |
| 1666 If you want to highlight delimiter characters (useful if you have a | |
| 1667 light-coloured background), add to your .vimrc: > | |
| 1668 :let hs_highlight_delimiters = 1 | |
| 1669 To treat True and False as keywords as opposed to ordinary identifiers, | |
| 1670 add: > | |
| 1671 :let hs_highlight_boolean = 1 | |
| 1672 To also treat the names of primitive types as keywords: > | |
| 1673 :let hs_highlight_types = 1 | |
| 1674 And to treat the names of even more relatively common types as keywords: > | |
| 1675 :let hs_highlight_more_types = 1 | |
| 1676 If you want to highlight the names of debugging functions, put in | |
| 1677 your .vimrc: > | |
| 1678 :let hs_highlight_debug = 1 | |
| 1679 | |
| 1680 The Haskell syntax highlighting also highlights C preprocessor | |
| 1681 directives, and flags lines that start with # but are not valid | |
| 237 | 1682 directives as erroneous. This interferes with Haskell's syntax for |
| 1683 operators, as they may start with #. If you want to highlight those | |
| 7 | 1684 as operators as opposed to errors, put in your .vimrc: > |
| 1685 :let hs_allow_hash_operator = 1 | |
| 1686 | |
| 1687 The syntax highlighting for literate Haskell code will try to | |
| 1688 automatically guess whether your literate Haskell code contains | |
| 1689 TeX markup or not, and correspondingly highlight TeX constructs | |
| 237 | 1690 or nothing at all. You can override this globally by putting |
| 7 | 1691 in your .vimrc > |
| 1692 :let lhs_markup = none | |
| 1693 for no highlighting at all, or > | |
| 1694 :let lhs_markup = tex | |
| 1695 to force the highlighting to always try to highlight TeX markup. | |
| 1696 For more flexibility, you may also use buffer local versions of | |
| 1697 this variable, so e.g. > | |
| 1698 :let b:lhs_markup = tex | |
| 237 | 1699 will force TeX highlighting for a particular buffer. It has to be |
| 7 | 1700 set before turning syntax highlighting on for the buffer or |
| 1701 loading a file. | |
| 1702 | |
| 1703 | |
| 501 | 1704 HTML *html.vim* *ft-html-syntax* |
| 7 | 1705 |
| 1706 The coloring scheme for tags in the HTML file works as follows. | |
| 1707 | |
| 1708 The <> of opening tags are colored differently than the </> of a closing tag. | |
| 1709 This is on purpose! For opening tags the 'Function' color is used, while for | |
| 1710 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
| 1711 defined for you) | |
| 1712 | |
| 1713 Known tag names are colored the same way as statements in C. Unknown tag | |
| 1714 names are colored with the same color as the <> or </> respectively which | |
| 1715 makes it easy to spot errors | |
| 1716 | |
| 237 | 1717 Note that the same is true for argument (or attribute) names. Known attribute |
| 7 | 1718 names are colored differently than unknown ones. |
| 1719 | |
| 237 | 1720 Some HTML tags are used to change the rendering of text. The following tags |
| 7 | 1721 are recognized by the html.vim syntax coloring file and change the way normal |
| 1722 text is shown: <B> <I> <U> <EM> <STRONG> (<EM> is used as an alias for <I>, | |
| 1723 while <STRONG> as an alias for <B>), <H1> - <H6>, <HEAD>, <TITLE> and <A>, but | |
| 237 | 1724 only if used as a link (that is, it must include a href as in |
| 1224 | 1725 <A href="somefile.html">). |
| 7 | 1726 |
| 1727 If you want to change how such text is rendered, you must redefine the | |
| 1728 following syntax groups: | |
| 1729 | |
| 1730 - htmlBold | |
| 1731 - htmlBoldUnderline | |
| 1732 - htmlBoldUnderlineItalic | |
| 1733 - htmlUnderline | |
| 1734 - htmlUnderlineItalic | |
| 1735 - htmlItalic | |
| 1736 - htmlTitle for titles | |
| 1737 - htmlH1 - htmlH6 for headings | |
| 1738 | |
| 1739 To make this redefinition work you must redefine them all with the exception | |
| 1740 of the last two (htmlTitle and htmlH[1-6], which are optional) and define the | |
| 1741 following variable in your vimrc (this is due to the order in which the files | |
| 1742 are read during initialization) > | |
| 1743 :let html_my_rendering=1 | |
| 1744 | |
| 1745 If you'd like to see an example download mysyntax.vim at | |
| 1746 http://www.fleiner.com/vim/download.html | |
| 1747 | |
| 1748 You can also disable this rendering by adding the following line to your | |
| 1749 vimrc file: > | |
| 1750 :let html_no_rendering=1 | |
| 1751 | |
| 1752 HTML comments are rather special (see an HTML reference document for the | |
| 1753 details), and the syntax coloring scheme will highlight all errors. | |
| 1754 However, if you prefer to use the wrong style (starts with <!-- and | |

1755 ends with -->) you can define > |
| 7 | 1756 :let html_wrong_comments=1 |
| 1757 | |
| 1758 JavaScript and Visual Basic embedded inside HTML documents are highlighted as | |
| 1759 'Special' with statements, comments, strings and so on colored as in standard | |
| 237 | 1760 programming languages. Note that only JavaScript and Visual Basic are currently |
| 7 | 1761 supported, no other scripting language has been added yet. |
| 1762 | |
| 1763 Embedded and inlined cascading style sheets (CSS) are highlighted too. | |
| 1764 | |
| 237 | 1765 There are several html preprocessor languages out there. html.vim has been |
| 1766 written such that it should be trivial to include it. To do so add the | |
| 7 | 1767 following two lines to the syntax coloring file for that language |
| 1768 (the example comes from the asp.vim file): | |
| 18016 | 1769 > |
| 7 | 1770 runtime! syntax/html.vim |
| 1771 syn cluster htmlPreproc add=asp | |
| 1772 | |
| 1773 Now you just need to make sure that you add all regions that contain | |
| 1774 the preprocessor language to the cluster htmlPreproc. | |
| 1775 | |
| 1776 | |
| 501 | 1777 HTML/OS (by Aestiva) *htmlos.vim* *ft-htmlos-syntax* |
| 7 | 1778 |
| 1779 The coloring scheme for HTML/OS works as follows: | |
| 1780 | |
| 1781 Functions and variable names are the same color by default, because VIM | |
| 1782 doesn't specify different colors for Functions and Identifiers. To change | |
| 1783 this (which is recommended if you want function names to be recognizable in a | |
| 1784 different color) you need to add the following line to either your ~/.vimrc: > | |
| 1785 :hi Function term=underline cterm=bold ctermfg=LightGray | |
| 1786 | |
| 1787 Of course, the ctermfg can be a different color if you choose. | |
| 1788 | |
| 1789 Another issues that HTML/OS runs into is that there is no special filetype to | |
| 1790 signify that it is a file with HTML/OS coding. You can change this by opening | |
| 1791 a file and turning on HTML/OS syntax by doing the following: > | |
| 1792 :set syntax=htmlos | |
| 1793 | |
| 1794 Lastly, it should be noted that the opening and closing characters to begin a | |
| 1795 block of HTML/OS code can either be << or [[ and >> or ]], respectively. | |
| 1796 | |

| 1809 Inform highlighting includes symbols provided by the Inform Library, as | |
| 1810 most programs make extensive use of it. If do not wish Library symbols | |
| 1811 to be highlighted add this to your vim startup: > | |
| 1812 :let inform_highlight_simple=1 | |
| 1813 | |
| 1814 By default it is assumed that Inform programs are Z-machine targeted, | |
| 1815 and highlights Z-machine assembly language symbols appropriately. If | |
| 1816 you intend your program to be targeted to a Glulx/Glk environment you | |
| 1817 need to add this to your startup sequence: > | |
| 1818 :let inform_highlight_glulx=1 | |
| 1819 | |
| 1820 This will highlight Glulx opcodes instead, and also adds glk() to the | |
| 1821 set of highlighted system functions. | |
| 1822 | |
| 1823 The Inform compiler will flag certain obsolete keywords as errors when | |
| 1824 it encounters them. These keywords are normally highlighted as errors | |
| 1825 by Vim. To prevent such error highlighting, you must add this to your | |
| 1826 startup sequence: > | |
| 1827 :let inform_suppress_obsolete=1 | |
| 1828 | |
| 1829 By default, the language features highlighted conform to Compiler | |
| 1830 version 6.30 and Library version 6.11. If you are using an older | |
| 1831 Inform development environment, you may with to add this to your | |
| 1832 startup sequence: > | |
| 1833 :let inform_highlight_old=1 | |
| 1834 | |
| 829 | 1835 IDL *idl.vim* *idl-syntax* |
| 1836 | |
| 1837 IDL (Interface Definition Language) files are used to define RPC calls. In | |
| 1838 Microsoft land, this is also used for defining COM interfaces and calls. | |
| 1839 | |
| 1840 IDL's structure is simple enough to permit a full grammar based approach to | |
| 1841 rather than using a few heuristics. The result is large and somewhat | |
| 1224 | 1842 repetitive but seems to work. |
| 829 | 1843 |
| 1844 There are some Microsoft extensions to idl files that are here. Some of them | |
| 1845 are disabled by defining idl_no_ms_extensions. | |
| 1846 | |
| 1847 The more complex of the extensions are disabled by defining idl_no_extensions. | |
| 1848 | |
| 1849 Variable Effect ~ | |
| 1850 | |
| 1851 idl_no_ms_extensions Disable some of the Microsoft specific | |
| 1852 extensions | |
| 1853 idl_no_extensions Disable complex extensions | |
| 1854 idlsyntax_showerror Show IDL errors (can be rather intrusive, but | |
| 1855 quite helpful) | |
| 1856 idlsyntax_showerror_soft Use softer colours by default for errors | |
| 1857 | |

| 501 | 1859 JAVA *java.vim* *ft-java-syntax* |
| 7 | 1860 |
| 1861 The java.vim syntax highlighting file offers several options: | |
| 1862 | |
| 1863 In Java 1.0.2 it was never possible to have braces inside parens, so this was | |
| 1864 flagged as an error. Since Java 1.1 this is possible (with anonymous | |
| 237 | 1865 classes), and therefore is no longer marked as an error. If you prefer the old |
| 7 | 1866 way, put the following line into your vim startup file: > |
| 1867 :let java_mark_braces_in_parens_as_errors=1 | |
| 1868 | |
| 1869 All identifiers in java.lang.* are always visible in all classes. To | |
| 1870 highlight them use: > | |
| 1871 :let java_highlight_java_lang_ids=1 | |
| 1872 | |
| 237 | 1873 You can also highlight identifiers of most standard Java packages if you |
| 7 | 1874 download the javaid.vim script at http://www.fleiner.com/vim/download.html. |
| 1875 If you prefer to only highlight identifiers of a certain package, say java.io | |
| 1876 use the following: > | |
| 1877 :let java_highlight_java_io=1 | |
| 1878 Check the javaid.vim file for a list of all the packages that are supported. | |
| 1879 | |
| 1880 Function names are not highlighted, as the way to find functions depends on | |
| 237 | 1881 how you write Java code. The syntax file knows two possible ways to highlight |
| 7 | 1882 functions: |
| 1883 | |
| 1884 If you write function declarations that are always indented by either | |
| 1885 a tab, 8 spaces or 2 spaces you may want to set > | |
| 1886 :let java_highlight_functions="indent" | |
| 1887 However, if you follow the Java guidelines about how functions and classes are | |
| 1888 supposed to be named (with respect to upper and lowercase), use > | |
| 1889 :let java_highlight_functions="style" | |
| 1890 If both options do not work for you, but you would still want function | |
| 1891 declarations to be highlighted create your own definitions by changing the | |
| 1892 definitions in java.vim or by creating your own java.vim which includes the | |
| 1893 original one and then adds the code to highlight functions. | |
| 1894 | |
| 237 | 1895 In Java 1.1 the functions System.out.println() and System.err.println() should |
| 8 | 1896 only be used for debugging. Therefore it is possible to highlight debugging |
| 237 | 1897 statements differently. To do this you must add the following definition in |
| 7 | 1898 your startup file: > |
| 1899 :let java_highlight_debug=1 | |
| 1900 The result will be that those statements are highlighted as 'Special' | |
| 237 | 1901 characters. If you prefer to have them highlighted differently you must define |
| 7 | 1902 new highlightings for the following groups.: |
| 1903 Debug, DebugSpecial, DebugString, DebugBoolean, DebugType | |
| 1904 which are used for the statement itself, special characters used in debug | |
| 237 | 1905 strings, strings, boolean constants and types (this, super) respectively. I |
| 7 | 1906 have opted to chose another background for those statements. |
| 1907 | |
| 237 | 1908 Javadoc is a program that takes special comments out of Java program files and |
| 1909 creates HTML pages. The standard configuration will highlight this HTML code | |
| 1910 similarly to HTML files (see |html.vim|). You can even add Javascript | |
| 1911 and CSS inside this code (see below). There are four differences however: | |
| 7 | 1912 1. The title (all characters up to the first '.' which is followed by |
| 1913 some white space or up to the first '@') is colored differently (to change | |
| 1914 the color change the group CommentTitle). | |
| 1915 2. The text is colored as 'Comment'. | |
| 1916 3. HTML comments are colored as 'Special' | |
| 237 | 1917 4. The special Javadoc tags (@see, @param, ...) are highlighted as specials |
| 7 | 1918 and the argument (for @see, @param, @exception) as Function. |
| 1919 To turn this feature off add the following line to your startup file: > | |
| 1920 :let java_ignore_javadoc=1 | |
| 1921 | |
| 237 | 1922 If you use the special Javadoc comment highlighting described above you |
| 1923 can also turn on special highlighting for Javascript, visual basic | |
| 1924 scripts and embedded CSS (stylesheets). This makes only sense if you | |
| 1925 actually have Javadoc comments that include either Javascript or embedded | |
| 1926 CSS. The options to use are > | |
| 7 | 1927 :let java_javascript=1 |
| 1928 :let java_css=1 | |
| 1929 :let java_vb=1 | |
| 1930 | |
| 1931 In order to highlight nested parens with different colors define colors | |
| 1932 for javaParen, javaParen1 and javaParen2, for example with > | |
| 1933 :hi link javaParen Comment | |
| 1934 or > | |
| 1935 :hi javaParen ctermfg=blue guifg=#0000ff | |
| 1936 | |
| 1937 If you notice highlighting errors while scrolling backwards, which are fixed | |
| 1938 when redrawing with CTRL-L, try setting the "java_minlines" internal variable | |
| 1939 to a larger number: > | |
| 1940 :let java_minlines = 50 | |
| 1941 This will make the syntax synchronization start 50 lines before the first | |
| 1942 displayed line. The default value is 10. The disadvantage of using a larger | |
| 1943 number is that redrawing can become slow. | |
| 1944 | |
| 1945 | |
| 18130 | 1946 JSON *json.vim* *ft-json-syntax* |
| 1947 | |
| 1948 The json syntax file provides syntax highlighting with conceal support by | |
| 1949 default. To disable concealment: > | |
| 1950 let g:vim_json_conceal = 0 | |
| 1951 | |
| 1952 To disable syntax highlighting of errors: > | |
| 1953 let g:vim_json_warnings = 0 | |
| 1954 | |
| 1955 | |
| 501 | 1956 LACE *lace.vim* *ft-lace-syntax* |
| 7 | 1957 |
| 1958 Lace (Language for Assembly of Classes in Eiffel) is case insensitive, but the | |
| 1959 style guide lines are not. If you prefer case insensitive highlighting, just | |
| 1960 define the vim variable 'lace_case_insensitive' in your startup file: > | |
| 1961 :let lace_case_insensitive=1 | |
| 1962 | |
| 1963 | |
| 501 | 1964 LEX *lex.vim* *ft-lex-syntax* |
| 7 | 1965 |
| 1966 Lex uses brute-force synchronizing as the "^%%$" section delimiter | |
| 1967 gives no clue as to what section follows. Consequently, the value for > | |
| 1968 :syn sync minlines=300 | |
| 1969 may be changed by the user if s/he is experiencing synchronization | |
| 1970 difficulties (such as may happen with large lex files). | |

| 555 | 1980 LISP *lisp.vim* *ft-lisp-syntax* |
| 1981 | |
| 1982 The lisp syntax highlighting provides two options: > | |
| 1983 | |
| 1984 g:lisp_instring : if it exists, then "(...)" strings are highlighted | |
| 1985 as if the contents of the string were lisp. | |
| 1986 Useful for AutoLisp. | |
| 1987 g:lisp_rainbow : if it exists and is nonzero, then differing levels | |
| 1988 of parenthesization will receive different | |
| 1989 highlighting. | |
| 1990 < | |
| 1991 The g:lisp_rainbow option provides 10 levels of individual colorization for | |
| 1992 the parentheses and backquoted parentheses. Because of the quantity of | |
| 1993 colorization levels, unlike non-rainbow highlighting, the rainbow mode | |
| 1994 specifies its highlighting using ctermfg and guifg, thereby bypassing the | |
| 16208 | 1995 usual color scheme control using standard highlighting groups. The actual |
| 555 | 1996 highlighting used depends on the dark/bright setting (see |'bg'|). |
| 1997 | |
| 1998 | |
| 501 | 1999 LITE *lite.vim* *ft-lite-syntax* |
| 7 | 2000 |
| 2001 There are two options for the lite syntax highlighting. | |
| 2002 | |
| 2003 If you like SQL syntax highlighting inside Strings, use this: > | |
| 2004 | |
| 2005 :let lite_sql_query = 1 | |
| 2006 | |
| 2007 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 2008 set "lite_minlines" to the value you desire. Example: > | |
| 2009 | |
| 2010 :let lite_minlines = 200 | |
| 2011 | |
| 2012 | |
| 501 | 2013 LPC *lpc.vim* *ft-lpc-syntax* |
| 7 | 2014 |
| 14123 | 2015 LPC stands for a simple, memory-efficient language: Lars Pensjö C. The |
| 7 | 2016 file name of LPC is usually *.c. Recognizing these files as LPC would bother |
| 2017 users writing only C programs. If you want to use LPC syntax in Vim, you | |
| 2018 should set a variable in your .vimrc file: > | |
| 2019 | |
| 2020 :let lpc_syntax_for_c = 1 | |
| 2021 | |
| 2022 If it doesn't work properly for some particular C or LPC files, use a | |
| 2023 modeline. For a LPC file: | |
| 2024 | |
| 2025 // vim:set ft=lpc: | |
| 2026 | |
| 2027 For a C file that is recognized as LPC: | |
| 2028 | |
| 2029 // vim:set ft=c: | |
| 2030 | |
| 2031 If you don't want to set the variable, use the modeline in EVERY LPC file. | |
| 2032 | |
| 2033 There are several implementations for LPC, we intend to support most widely | |
| 237 | 2034 used ones. Here the default LPC syntax is for MudOS series, for MudOS v22 |
| 7 | 2035 and before, you should turn off the sensible modifiers, and this will also |
| 5814 | 2036 assert the new efuns after v22 to be invalid, don't set this variable when |
| 7 | 2037 you are using the latest version of MudOS: > |
| 2038 | |
| 2039 :let lpc_pre_v22 = 1 | |
| 2040 | |
| 2041 For LpMud 3.2 series of LPC: > | |
| 2042 | |
| 2043 :let lpc_compat_32 = 1 | |
| 2044 | |
| 2045 For LPC4 series of LPC: > | |
| 2046 | |
| 2047 :let lpc_use_lpc4_syntax = 1 | |
| 2048 | |
| 2049 For uLPC series of LPC: | |
| 2050 uLPC has been developed to Pike, so you should use Pike syntax | |
| 2051 instead, and the name of your source file should be *.pike | |
| 2052 | |
| 2053 | |
| 501 | 2054 LUA *lua.vim* *ft-lua-syntax* |
| 7 | 2055 |
| 3356 | 2056 The Lua syntax file can be used for versions 4.0, 5.0, 5.1 and 5.2 (5.2 is |
| 838 | 2057 the default). You can select one of these versions using the global variables |
| 2058 lua_version and lua_subversion. For example, to activate Lua | |
| 3356 | 2059 5.1 syntax highlighting, set the variables like this: |
| 838 | 2060 |
| 2061 :let lua_version = 5 | |
| 2062 :let lua_subversion = 1 | |
| 7 | 2063 |
| 2064 | |
| 501 | 2065 MAIL *mail.vim* *ft-mail.vim* |
| 7 | 2066 |
| 2067 Vim highlights all the standard elements of an email (headers, signatures, | |
| 237 | 2068 quoted text and URLs / email addresses). In keeping with standard conventions, |
| 7 | 2069 signatures begin in a line containing only "--" followed optionally by |
| 2070 whitespaces and end with a newline. | |
| 2071 | |
| 2072 Vim treats lines beginning with ']', '}', '|', '>' or a word followed by '>' | |
| 237 | 2073 as quoted text. However Vim highlights headers and signatures in quoted text |
| 7 | 2074 only if the text is quoted with '>' (optionally followed by one space). |
| 2075 | |
| 2076 By default mail.vim synchronises syntax to 100 lines before the first | |
| 237 | 2077 displayed line. If you have a slow machine, and generally deal with emails |
| 7 | 2078 with short headers, you can change this to a smaller value: > |
| 2079 | |
| 2080 :let mail_minlines = 30 | |
| 2081 | |
| 2082 | |
| 501 | 2083 MAKE *make.vim* *ft-make-syntax* |
| 7 | 2084 |
| 2085 In makefiles, commands are usually highlighted to make it easy for you to spot | |
| 2086 errors. However, this may be too much coloring for you. You can turn this | |
| 2087 feature off by using: > | |
| 2088 | |
| 2089 :let make_no_commands = 1 | |
| 2090 | |
| 2091 | |
| 501 | 2092 MAPLE *maple.vim* *ft-maple-syntax* |

| 2094 Maple V, by Waterloo Maple Inc, supports symbolic algebra. The language | |
| 2095 supports many packages of functions which are selectively loaded by the user. | |
| 2096 The standard set of packages' functions as supplied in Maple V release 4 may be | |
| 2097 highlighted at the user's discretion. Users may place in their .vimrc file: > | |
| 2098 | |
| 2099 :let mvpkg_all= 1 | |
| 2100 | |
| 2101 to get all package functions highlighted, or users may select any subset by | |
| 2102 choosing a variable/package from the table below and setting that variable to | |
| 2103 1, also in their .vimrc file (prior to sourcing | |
| 2104 $VIMRUNTIME/syntax/syntax.vim). | |

| 7 | 2126 |
| 2127 If you use C-style comments inside expressions and find it mangles your | |
| 2128 highlighting, you may want to use extended (slow!) matches for C-style | |
| 2129 comments: > | |

| 2146 To highlight builtin properties (.name, .location, .programmer etc.): > | |
| 2147 | |
| 2148 :let moo_builtin_properties = 1 | |
| 2149 | |
| 237 | 2150 Unknown builtin functions can be recognized and highlighted as errors. If you |
| 7 | 2151 use this option, add your own extensions to the mooKnownBuiltinFunction group. |
| 2152 To enable this option: > | |
| 2153 | |
| 2154 :let moo_unknown_builtin_functions = 1 | |
| 2155 | |
| 2156 An example of adding sprintf() to the list of known builtin functions: > | |

| 2159 | |
| 2160 | |
| 501 | 2161 MSQL *msql.vim* *ft-msql-syntax* |
| 7 | 2162 |
| 2163 There are two options for the msql syntax highlighting. | |
| 2164 | |
| 2165 If you like SQL syntax highlighting inside Strings, use this: > | |
| 2166 | |
| 2167 :let msql_sql_query = 1 | |
| 2168 | |
| 2169 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 2170 set "msql_minlines" to the value you desire. Example: > | |
| 2171 | |
| 2172 :let msql_minlines = 200 | |
| 2173 | |
| 2174 | |
| 12254 | 2175 N1QL *n1ql.vim* *ft-n1ql-syntax* |
| 2176 | |
| 2177 N1QL is a SQL-like declarative language for manipulating JSON documents in | |
| 2178 Couchbase Server databases. | |
| 2179 | |
| 2180 Vim syntax highlights N1QL statements, keywords, operators, types, comments, | |
| 2181 and special values. Vim ignores syntactical elements specific to SQL or its | |
| 2182 many dialects, like COLUMN or CHAR, that don't exist in N1QL. | |
| 2183 | |
| 2184 | |
| 501 | 2185 NCF *ncf.vim* *ft-ncf-syntax* |
| 7 | 2186 |
| 2187 There is one option for NCF syntax highlighting. | |
| 2188 | |
| 2189 If you want to have unrecognized (by ncf.vim) statements highlighted as | |
| 2190 errors, use this: > | |
| 2191 | |
| 2192 :let ncf_highlight_unknowns = 1 | |
| 2193 | |
| 2194 If you don't want to highlight these errors, leave it unset. | |
| 2195 | |
| 2196 | |
| 501 | 2197 NROFF *nroff.vim* *ft-nroff-syntax* |
| 7 | 2198 |
| 2199 The nroff syntax file works with AT&T n/troff out of the box. You need to | |
| 2200 activate the GNU groff extra features included in the syntax file before you | |
| 2201 can use them. | |
| 2202 | |
| 2203 For example, Linux and BSD distributions use groff as their default text | |
| 237 | 2204 processing package. In order to activate the extra syntax highlighting |
| 7 | 2205 features for groff, add the following option to your start-up files: > |
| 2206 | |
| 2207 :let b:nroff_is_groff = 1 | |
| 2208 | |
| 2209 Groff is different from the old AT&T n/troff that you may still find in | |
| 2210 Solaris. Groff macro and request names can be longer than 2 characters and | |
| 2211 there are extensions to the language primitives. For example, in AT&T troff | |
| 237 | 2212 you access the year as a 2-digit number with the request \(yr. In groff you |
| 7 | 2213 can use the same request, recognized for compatibility, or you can use groff's |
| 2214 native syntax, \[yr]. Furthermore, you can use a 4-digit year directly: | |
| 2215 \[year]. Macro requests can be longer than 2 characters, for example, GNU mm | |
| 2216 accepts the requests ".VERBON" and ".VERBOFF" for creating verbatim | |
| 2217 environments. | |
| 2218 | |
| 2219 In order to obtain the best formatted output g/troff can give you, you should | |
| 2220 follow a few simple rules about spacing and punctuation. | |
| 2221 | |
| 2222 1. Do not leave empty spaces at the end of lines. | |
| 2223 | |
| 2224 2. Leave one space and one space only after an end-of-sentence period, | |
| 2225 exclamation mark, etc. | |
| 2226 | |
| 2227 3. For reasons stated below, it is best to follow all period marks with a | |
| 2228 carriage return. | |
| 2229 | |
| 2230 The reason behind these unusual tips is that g/n/troff have a line breaking | |
| 2231 algorithm that can be easily upset if you don't follow the rules given above. | |
| 2232 | |
| 2233 Unlike TeX, troff fills text line-by-line, not paragraph-by-paragraph and, | |
| 2234 furthermore, it does not have a concept of glue or stretch, all horizontal and | |
| 2235 vertical space input will be output as is. | |
| 2236 | |
| 2237 Therefore, you should be careful about not using more space between sentences | |
| 2238 than you intend to have in your final document. For this reason, the common | |
| 2239 practice is to insert a carriage return immediately after all punctuation | |
| 237 | 2240 marks. If you want to have "even" text in your final processed output, you |
| 4264 | 2241 need to maintain regular spacing in the input text. To mark both trailing |
| 7 | 2242 spaces and two or more spaces after a punctuation as an error, use: > |
| 2243 | |
| 2244 :let nroff_space_errors = 1 | |
| 2245 | |
| 2246 Another technique to detect extra spacing and other errors that will interfere | |
| 2247 with the correct typesetting of your file, is to define an eye-catching | |
| 2248 highlighting definition for the syntax groups "nroffDefinition" and | |
| 237 | 2249 "nroffDefSpecial" in your configuration files. For example: > |
| 7 | 2250 |
| 2251 hi def nroffDefinition term=italic cterm=italic gui=reverse | |
| 2252 hi def nroffDefSpecial term=italic,bold cterm=italic,bold | |
| 2253 \ gui=reverse,bold | |
| 2254 | |
| 2255 If you want to navigate preprocessor entries in your source file as easily as | |
| 2256 with section markers, you can activate the following option in your .vimrc | |
| 2257 file: > | |
| 2258 | |
| 2259 let b:preprocs_as_sections = 1 | |
| 2260 | |
| 9 | 2261 As well, the syntax file adds an extra paragraph marker for the extended |
| 7 | 2262 paragraph macro (.XP) in the ms package. |
| 2263 | |
| 2264 Finally, there is a |groff.vim| syntax file that can be used for enabling | |
| 2265 groff syntax highlighting either on a file basis or globally by default. | |
| 2266 | |
| 2267 | |
| 501 | 2268 OCAML *ocaml.vim* *ft-ocaml-syntax* |
| 7 | 2269 |
| 2270 The OCaml syntax file handles files having the following prefixes: .ml, | |
| 2271 .mli, .mll and .mly. By setting the following variable > | |
| 2272 | |
| 2273 :let ocaml_revised = 1 | |
| 2274 | |
| 2275 you can switch from standard OCaml-syntax to revised syntax as supported | |
| 2276 by the camlp4 preprocessor. Setting the variable > | |
| 2277 | |
| 2278 :let ocaml_noend_error = 1 | |
| 2279 | |
| 2280 prevents highlighting of "end" as error, which is useful when sources | |
| 2281 contain very long structures that Vim does not synchronize anymore. | |
| 2282 | |
| 2283 | |
| 501 | 2284 PAPP *papp.vim* *ft-papp-syntax* |
| 7 | 2285 |
| 2286 The PApp syntax file handles .papp files and, to a lesser extend, .pxml | |
| 2287 and .pxsl files which are all a mixture of perl/xml/html/other using xml | |
| 237 | 2288 as the top-level file format. By default everything inside phtml or pxml |
| 2289 sections is treated as a string with embedded preprocessor commands. If | |
| 7 | 2290 you set the variable: > |
| 2291 | |
| 2292 :let papp_include_html=1 | |
| 2293 | |
| 2294 in your startup file it will try to syntax-hilight html code inside phtml | |
| 2295 sections, but this is relatively slow and much too colourful to be able to | |
| 237 | 2296 edit sensibly. ;) |
| 7 | 2297 |
| 2298 The newest version of the papp.vim syntax file can usually be found at | |
| 2299 http://papp.plan9.de. | |
| 2300 | |
| 2301 | |
| 501 | 2302 PASCAL *pascal.vim* *ft-pascal-syntax* |
| 7 | 2303 |
| 2304 Files matching "*.p" could be Progress or Pascal. If the automatic detection | |
| 2305 doesn't work for you, or you don't edit Progress at all, use this in your | |
| 2306 startup vimrc: > | |
| 2307 | |
| 2308 :let filetype_p = "pascal" | |
| 2309 | |
| 2310 The Pascal syntax file has been extended to take into account some extensions | |
| 2311 provided by Turbo Pascal, Free Pascal Compiler and GNU Pascal Compiler. | |
| 237 | 2312 Delphi keywords are also supported. By default, Turbo Pascal 7.0 features are |
| 7 | 2313 enabled. If you prefer to stick with the standard Pascal keywords, add the |
| 2314 following line to your startup file: > | |
| 2315 | |
| 2316 :let pascal_traditional=1 | |
| 2317 | |
| 2318 To switch on Delphi specific constructions (such as one-line comments, | |
| 2319 keywords, etc): > | |
| 2320 | |
| 2321 :let pascal_delphi=1 | |
| 2322 | |
| 2323 | |
| 2324 The option pascal_symbol_operator controls whether symbol operators such as +, | |
| 2325 *, .., etc. are displayed using the Operator color or not. To colorize symbol | |
| 2326 operators, add the following line to your startup file: > | |
| 2327 | |
| 2328 :let pascal_symbol_operator=1 | |
| 2329 | |
| 2330 Some functions are highlighted by default. To switch it off: > | |
| 2331 | |
| 2332 :let pascal_no_functions=1 | |
| 2333 | |

2334 Furthermore, there are specific variables for some compilers. Besides |
| 7 | 2335 pascal_delphi, there are pascal_gpc and pascal_fpc. Default extensions try to |
| 2336 match Turbo Pascal. > | |

| 2344 To ensure that strings are defined on a single line, you can define the | |
| 2345 pascal_one_line_string variable. > | |
| 2346 | |
| 2347 :let pascal_one_line_string=1 | |
| 2348 | |
| 2349 If you dislike <Tab> chars, you can set the pascal_no_tabs variable. Tabs | |
| 2350 will be highlighted as Error. > | |

| 501 | 2356 PERL *perl.vim* *ft-perl-syntax* |
| 7 | 2357 |
| 2358 There are a number of possible options to the perl syntax highlighting. | |
| 2359 | |
| 4992 | 2360 Inline POD highlighting is now turned on by default. If you don't wish |
| 2361 to have the added complexity of highlighting POD embedded within Perl | |
| 2362 files, you may set the 'perl_include_pod' option to 0: > | |
| 2363 | |
| 2364 :let perl_include_pod = 0 | |
| 7 | 2365 |
| 5968 | 2366 To reduce the complexity of parsing (and increase performance) you can switch |
| 22 | 2367 off two elements in the parsing of variable names and contents. > |
| 2368 | |
| 2369 To handle package references in variable and function names not differently | |
| 2370 from the rest of the name (like 'PkgName::' in '$PkgName::VarName'): > | |
| 2371 | |
| 2372 :let perl_no_scope_in_variables = 1 | |
| 2373 | |
| 2374 (In Vim 6.x it was the other way around: "perl_want_scope_in_variables" | |
| 2375 enabled it.) | |
| 2376 | |
| 2377 If you do not want complex things like '@{${"foo"}}' to be parsed: > | |
| 2378 | |
| 2379 :let perl_no_extended_vars = 1 | |
| 2380 | |
| 26 | 2381 (In Vim 6.x it was the other way around: "perl_extended_vars" enabled it.) |
| 7 | 2382 |
| 237 | 2383 The coloring strings can be changed. By default strings and qq friends will be |
| 2384 highlighted like the first line. If you set the variable | |
| 7 | 2385 perl_string_as_statement, it will be highlighted as in the second line. |
| 2386 | |
| 2387 "hello world!"; qq|hello world|; | |
| 2388 ^^^^^^^^^^^^^^NN^^^^^^^^^^^^^^^N (unlet perl_string_as_statement) | |
| 2389 S^^^^^^^^^^^^SNNSSS^^^^^^^^^^^SN (let perl_string_as_statement) | |
| 2390 | |
| 2391 (^ = perlString, S = perlStatement, N = None at all) | |
| 2392 | |
| 237 | 2393 The syncing has 3 options. The first two switch off some triggering of |
| 7 | 2394 synchronization and should only be needed in case it fails to work properly. |
| 2395 If while scrolling all of a sudden the whole screen changes color completely | |
| 237 | 2396 then you should try and switch off one of those. Let me know if you can figure |
| 7 | 2397 out the line that causes the mistake. |
| 2398 | |
| 2399 One triggers on "^\s*sub\s*" and the other on "^[$@%]" more or less. > | |
| 2400 | |
| 2401 :let perl_no_sync_on_sub | |
| 2402 :let perl_no_sync_on_global_var | |
| 2403 | |
| 2404 Below you can set the maximum distance VIM should look for starting points for | |
| 2405 its attempts in syntax highlighting. > | |
| 2406 | |
| 2407 :let perl_sync_dist = 100 | |
| 2408 | |
| 2409 If you want to use folding with perl, set perl_fold: > | |
| 2410 | |
| 22 | 2411 :let perl_fold = 1 |
| 2412 | |
| 2413 If you want to fold blocks in if statements, etc. as well set the following: > | |
| 2414 | |
| 2415 :let perl_fold_blocks = 1 | |
| 7 | 2416 |
| 4992 | 2417 Subroutines are folded by default if 'perl_fold' is set. If you do not want |
| 2418 this, you can set 'perl_nofold_subs': > | |
| 2419 | |
| 2420 :let perl_nofold_subs = 1 | |
| 2421 | |
| 2422 Anonymous subroutines are not folded by default; you may enable their folding | |
| 2423 via 'perl_fold_anonymous_subs': > | |
| 2424 | |
| 2425 :let perl_fold_anonymous_subs = 1 | |
| 2426 | |
| 2427 Packages are also folded by default if 'perl_fold' is set. To disable this | |
| 2428 behavior, set 'perl_nofold_packages': > | |
| 2429 | |
| 2430 :let perl_nofold_packages = 1 | |

| 501 | 2498 PPWIZARD *ppwiz.vim* *ft-ppwiz-syntax* |
| 7 | 2499 |
| 2500 PPWizard is a preprocessor for HTML and OS/2 INF files | |
| 2501 | |
| 2502 This syntax file has the options: | |
| 2503 | |
| 2504 - ppwiz_highlight_defs : determines highlighting mode for PPWizard's | |
| 237 | 2505 definitions. Possible values are |
| 7 | 2506 |
| 2507 ppwiz_highlight_defs = 1 : PPWizard #define statements retain the | |
| 237 | 2508 colors of their contents (e.g. PPWizard macros and variables) |
| 7 | 2509 |
| 2510 ppwiz_highlight_defs = 2 : preprocessor #define and #evaluate | |
| 2511 statements are shown in a single color with the exception of line | |
| 2512 continuation symbols | |
| 2513 | |
| 2514 The default setting for ppwiz_highlight_defs is 1. | |
| 2515 | |
| 2516 - ppwiz_with_html : If the value is 1 (the default), highlight literal | |
| 2517 HTML code; if 0, treat HTML code like ordinary text. | |
| 2518 | |
| 2519 | |
| 501 | 2520 PHTML *phtml.vim* *ft-phtml-syntax* |
| 7 | 2521 |
| 2522 There are two options for the phtml syntax highlighting. | |
| 2523 | |
| 2524 If you like SQL syntax highlighting inside Strings, use this: > | |
| 2525 | |
| 2526 :let phtml_sql_query = 1 | |
| 2527 | |
| 2528 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 2529 set "phtml_minlines" to the value you desire. Example: > | |
| 2530 | |
| 2531 :let phtml_minlines = 200 | |
| 2532 | |
| 2533 | |
| 501 | 2534 POSTSCRIPT *postscr.vim* *ft-postscr-syntax* |
| 7 | 2535 |
| 2536 There are several options when it comes to highlighting PostScript. | |
| 2537 | |
| 2538 First which version of the PostScript language to highlight. There are | |
| 2539 currently three defined language versions, or levels. Level 1 is the original | |
| 2540 and base version, and includes all extensions prior to the release of level 2. | |
| 2541 Level 2 is the most common version around, and includes its own set of | |
| 2542 extensions prior to the release of level 3. Level 3 is currently the highest | |
| 2543 level supported. You select which level of the PostScript language you want | |
| 2544 highlighted by defining the postscr_level variable as follows: > | |
| 2545 | |
| 2546 :let postscr_level=2 | |
| 2547 | |
| 2548 If this variable is not defined it defaults to 2 (level 2) since this is | |
| 2549 the most prevalent version currently. | |
| 2550 | |
| 2551 Note, not all PS interpreters will support all language features for a | |
| 2552 particular language level. In particular the %!PS-Adobe-3.0 at the start of | |
| 2553 PS files does NOT mean the PostScript present is level 3 PostScript! | |
| 2554 | |
| 2555 If you are working with Display PostScript, you can include highlighting of | |
| 2556 Display PS language features by defining the postscr_display variable as | |
| 2557 follows: > | |
| 2558 | |
| 2559 :let postscr_display=1 | |
| 2560 | |
| 2561 If you are working with Ghostscript, you can include highlighting of | |
| 2562 Ghostscript specific language features by defining the variable | |
| 2563 postscr_ghostscript as follows: > | |
| 2564 | |
| 2565 :let postscr_ghostscript=1 | |
| 2566 | |
| 2567 PostScript is a large language, with many predefined elements. While it | |
| 2568 useful to have all these elements highlighted, on slower machines this can | |
| 2569 cause Vim to slow down. In an attempt to be machine friendly font names and | |
| 2570 character encodings are not highlighted by default. Unless you are working | |
| 2571 explicitly with either of these this should be ok. If you want them to be | |
| 2572 highlighted you should set one or both of the following variables: > | |
| 2573 | |
| 2574 :let postscr_fonts=1 | |
| 2575 :let postscr_encodings=1 | |
| 2576 | |
| 2577 There is a stylistic option to the highlighting of and, or, and not. In | |
| 2578 PostScript the function of these operators depends on the types of their | |
| 2579 operands - if the operands are booleans then they are the logical operators, | |
| 2580 if they are integers then they are binary operators. As binary and logical | |
| 2581 operators can be highlighted differently they have to be highlighted one way | |
| 2582 or the other. By default they are treated as logical operators. They can be | |
| 2583 highlighted as binary operators by defining the variable | |
| 2584 postscr_andornot_binary as follows: > | |
| 2585 | |
| 2586 :let postscr_andornot_binary=1 | |
| 2587 < | |
| 2588 | |
| 501 | 2589 *ptcap.vim* *ft-printcap-syntax* |
| 2590 PRINTCAP + TERMCAP *ft-ptcap-syntax* *ft-termcap-syntax* | |
| 7 | 2591 |
| 2592 This syntax file applies to the printcap and termcap databases. | |
| 2593 | |
| 2594 In order for Vim to recognize printcap/termcap files that do not match | |
| 2595 the patterns *printcap*, or *termcap*, you must put additional patterns | |
| 2596 appropriate to your system in your |myfiletypefile| file. For these | |
| 2597 patterns, you must set the variable "b:ptcap_type" to either "print" or | |
| 2598 "term", and then the 'filetype' option to ptcap. | |
| 2599 | |
| 2600 For example, to make Vim identify all files in /etc/termcaps/ as termcap | |
| 2601 files, add the following: > | |
| 2602 | |
| 2603 :au BufNewFile,BufRead /etc/termcaps/* let b:ptcap_type = "term" | | |
| 2604 \ set filetype=ptcap | |
| 2605 | |
| 2606 If you notice highlighting errors while scrolling backwards, which | |
| 2607 are fixed when redrawing with CTRL-L, try setting the "ptcap_minlines" | |
| 2608 internal variable to a larger number: > | |
| 2609 | |
| 2610 :let ptcap_minlines = 50 | |
| 2611 | |
| 2612 (The default is 20 lines.) | |
| 2613 | |
| 2614 | |
| 501 | 2615 PROGRESS *progress.vim* *ft-progress-syntax* |
| 7 | 2616 |
| 2617 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
| 2618 doesn't work for you, or you don't edit cweb at all, use this in your | |
| 2619 startup vimrc: > | |
| 2620 :let filetype_w = "progress" | |
| 2621 The same happens for "*.i", which could be assembly, and "*.p", which could be | |
| 2622 Pascal. Use this if you don't use assembly and Pascal: > | |
| 2623 :let filetype_i = "progress" | |
| 2624 :let filetype_p = "progress" | |
| 2625 | |
| 2626 | |
| 501 | 2627 PYTHON *python.vim* *ft-python-syntax* |
| 7 | 2628 |
| 4186 | 2629 There are six options to control Python syntax highlighting. |

| 4186 | 2647 :let python_space_error_highlight = 1 |
| 7 | 2648 |
| 2649 If you want all possible Python highlighting (the same as setting the | |
| 4186 | 2650 preceding last option and unsetting all other ones): > |
| 7 | 2651 :let python_highlight_all = 1 |
| 2652 | |
| 4992 | 2653 Note: only existence of these options matter, not their value. You can replace |
| 4186 | 2654 1 above with anything. |
| 2655 | |
| 501 | 2656 QUAKE *quake.vim* *ft-quake-syntax* |
| 7 | 2657 |
| 2658 The Quake syntax definition should work for most any FPS (First Person | |
| 237 | 2659 Shooter) based on one of the Quake engines. However, the command names vary |
| 7 | 2660 a bit between the three games (Quake, Quake 2, and Quake 3 Arena) so the |
| 2661 syntax definition checks for the existence of three global variables to allow | |
| 237 | 2662 users to specify what commands are legal in their files. The three variables |
| 7 | 2663 can be set for the following effects: |
| 2664 | |
| 2665 set to highlight commands only available in Quake: > | |
| 2666 :let quake_is_quake1 = 1 | |
| 2667 | |
| 2668 set to highlight commands only available in Quake 2: > | |
| 2669 :let quake_is_quake2 = 1 | |
| 2670 | |
| 2671 set to highlight commands only available in Quake 3 Arena: > | |
| 2672 :let quake_is_quake3 = 1 | |
| 2673 | |
| 2674 Any combination of these three variables is legal, but might highlight more | |
| 2675 commands than are actually available to you by the game. | |
| 2676 | |
| 2677 | |
| 14637 | 2678 R *r.vim* *ft-r-syntax* |
| 2679 | |
| 2680 The parsing of R code for syntax highlight starts 40 lines backwards, but you | |
| 2681 can set a different value in your |vimrc|. Example: > | |
| 2682 let r_syntax_minlines = 60 | |
| 2683 | |
| 2684 You can also turn off syntax highlighting of ROxygen: > | |
| 2685 let r_syntax_hl_roxygen = 0 | |
| 2686 | |
| 2687 enable folding of code delimited by parentheses, square brackets and curly | |
| 2688 braces: > | |
| 2689 let r_syntax_folding = 1 | |
| 2690 | |
| 2691 and highlight as functions all keywords followed by an opening parenthesis: > | |
| 2692 let r_syntax_fun_pattern = 1 | |
| 2693 | |
| 2694 | |
| 2695 R MARKDOWN *rmd.vim* *ft-rmd-syntax* | |
| 2696 | |
| 2697 To disable syntax highlight of YAML header, add to your |vimrc|: > | |
| 2698 let rmd_syn_hl_yaml = 0 | |
| 2699 | |
| 2700 To disable syntax highlighting of citation keys: > | |
| 2701 let rmd_syn_hl_citations = 0 | |
| 2702 | |
| 2703 To highlight R code in knitr chunk headers: > | |
| 2704 let rmd_syn_hl_chunk = 1 | |
| 2705 | |
| 2706 By default, chunks of R code will be highlighted following the rules of R | |
| 2707 language. If you want proper syntax highlighting of chunks of other languages, | |
| 2708 you should add them to either `markdown_fenced_languages` or | |
| 2709 `rmd_fenced_languages`. For example to properly highlight both R and Python, | |
| 2710 you may add this to your |vimrc|: > | |
| 2711 let rmd_fenced_languages = ['r', 'python'] | |
| 2712 | |
| 2713 | |
| 2714 R RESTRUCTURED TEXT *rrst.vim* *ft-rrst-syntax* | |
| 2715 | |
| 2716 To highlight R code in knitr chunk headers, add to your |vimrc|: > | |
| 2717 let rrst_syn_hl_chunk = 1 | |
| 2718 | |
| 2719 | |
| 501 | 2720 READLINE *readline.vim* *ft-readline-syntax* |
| 7 | 2721 |
| 2722 The readline library is primarily used by the BASH shell, which adds quite a | |
| 237 | 2723 few commands and options to the ones already available. To highlight these |
| 7 | 2724 items as well you can add the following to your |vimrc| or just type it in the |
| 2725 command line before loading a file with the readline syntax: > | |
| 2726 let readline_has_bash = 1 | |
| 2727 | |
| 2728 This will add highlighting for the commands that BASH (version 2.05a and | |
| 2729 later, and part earlier) adds. | |
| 2730 | |
| 2731 | |
| 3920 | 2732 RESTRUCTURED TEXT *rst.vim* *ft-rst-syntax* |
| 2733 | |
| 15334 | 2734 Syntax highlighting is enabled for code blocks within the document for a |
| 2735 select number of file types. See $VIMRUNTIME/syntax/rst.vim for the default | |
| 2736 syntax list. | |
| 2737 | |
| 2738 To set a user-defined list of code block syntax highlighting: > | |
| 3920 | 2739 let rst_syntax_code_list = ['vim', 'lisp', ...] |
| 15334 | 2740 |
| 2741 To assign multiple code block types to a single syntax, define | |
| 2742 `rst_syntax_code_list` as a mapping: > | |
| 2743 let rst_syntax_code_list = { | |
| 2744 \ 'cpp' = ['cpp', 'c++'], | |
| 2745 \ 'bash' = ['bash', 'sh'], | |
| 2746 ... | |
| 2747 } | |
| 2748 | |
| 2749 To use color highlighting for emphasis text: > | |
| 2750 let rst_use_emphasis_colors = 1 | |
| 2751 | |
| 2752 To enable folding of sections: > | |
| 2753 let rst_fold_enabled = 1 | |
| 2754 | |
| 2755 Note that folding can cause performance issues on some platforms. | |
| 2756 | |
| 3920 | 2757 |
| 501 | 2758 REXX *rexx.vim* *ft-rexx-syntax* |
| 7 | 2759 |
| 2760 If you notice highlighting errors while scrolling backwards, which are fixed | |
| 2761 when redrawing with CTRL-L, try setting the "rexx_minlines" internal variable | |
| 2762 to a larger number: > | |
| 2763 :let rexx_minlines = 50 | |
| 2764 This will make the syntax synchronization start 50 lines before the first | |
| 2765 displayed line. The default value is 10. The disadvantage of using a larger | |
| 2766 number is that redrawing can become slow. | |
| 2767 | |
| 2965 | 2768 Vim tries to guess what type a ".r" file is. If it can't be detected (from |
| 2769 comment lines), the default is "r". To make the default rexx add this line to | |
| 2770 your .vimrc: *g:filetype_r* | |
| 2771 > | |
| 2772 :let g:filetype_r = "r" | |
| 2773 | |

2845 Ruby: Reducing expensive operations ~ |
| 7 | 2846 |
| 2847 By default, the "end" keyword is colorized according to the opening statement | |
| 572 | 2848 of the block it closes. While useful, this feature can be expensive; if you |
| 7 | 2849 experience slow redrawing (or you are on a terminal with poor color support) |
| 2850 you may want to turn it off by defining the "ruby_no_expensive" variable: > | |
| 572 | 2851 |
| 7 | 2852 :let ruby_no_expensive = 1 |
| 1224 | 2853 < |
| 7 | 2854 In this case the same color will be used for all control keywords. |

2857 |
| 7 | 2858 If you do want this feature enabled, but notice highlighting errors while |
| 2859 scrolling backwards, which are fixed when redrawing with CTRL-L, try setting | |
| 2860 the "ruby_minlines" variable to a value larger than 50: > | |
| 572 | 2861 |
| 7 | 2862 :let ruby_minlines = 100 |
| 1224 | 2863 < |
| 7 | 2864 Ideally, this value should be a number of lines large enough to embrace your |
| 2865 largest class or module. | |

| 1224 | 2874 < |
| 1125 | 2875 |
| 501 | 2876 SCHEME *scheme.vim* *ft-scheme-syntax* |
| 17 | 2877 |
| 13231 | 2878 By default only R7RS keywords are highlighted and properly indented. |
| 2879 | |
| 2880 scheme.vim also supports extensions of the CHICKEN Scheme->C compiler. | |
| 2881 Define b:is_chicken or g:is_chicken, if you need them. | |
| 17 | 2882 |
| 2883 | |
| 501 | 2884 SDL *sdl.vim* *ft-sdl-syntax* |
| 7 | 2885 |
| 2886 The SDL highlighting probably misses a few keywords, but SDL has so many | |
| 2887 of them it's almost impossibly to cope. | |
| 2888 | |
| 2889 The new standard, SDL-2000, specifies that all identifiers are | |
| 2890 case-sensitive (which was not so before), and that all keywords can be | |
| 237 | 2891 used either completely lowercase or completely uppercase. To have the |
| 7 | 2892 highlighting reflect this, you can set the following variable: > |
| 2893 :let sdl_2000=1 | |
| 2894 | |
| 237 | 2895 This also sets many new keywords. If you want to disable the old |
| 7 | 2896 keywords, which is probably a good idea, use: > |
| 2897 :let SDL_no_96=1 | |
| 2898 | |
| 2899 | |
| 2900 The indentation is probably also incomplete, but right now I am very | |
| 2901 satisfied with it for my own projects. | |
| 2902 | |
| 2903 | |
| 501 | 2904 SED *sed.vim* *ft-sed-syntax* |
| 7 | 2905 |
| 2906 To make tabs stand out from regular blanks (accomplished by using Todo | |
| 2907 highlighting on the tabs), define "highlight_sedtabs" by putting > | |
| 2908 | |
| 2909 :let highlight_sedtabs = 1 | |
| 2910 | |
| 2911 in the vimrc file. (This special highlighting only applies for tabs | |
| 2912 inside search patterns, replacement texts, addresses or text included | |
| 2913 by an Append/Change/Insert command.) If you enable this option, it is | |
| 2914 also a good idea to set the tab width to one character; by doing that, | |
| 2915 you can easily count the number of tabs in a string. | |
| 2916 | |
| 2917 Bugs: | |
| 2918 | |
| 2919 The transform command (y) is treated exactly like the substitute | |
| 2920 command. This means that, as far as this syntax file is concerned, | |
| 2921 transform accepts the same flags as substitute, which is wrong. | |
| 2922 (Transform accepts no flags.) I tolerate this bug because the | |
| 2923 involved commands need very complex treatment (95 patterns, one for | |
| 2924 each plausible pattern delimiter). | |
| 2925 | |
| 2926 | |
| 501 | 2927 SGML *sgml.vim* *ft-sgml-syntax* |
| 7 | 2928 |
| 2929 The coloring scheme for tags in the SGML file works as follows. | |
| 2930 | |
| 2931 The <> of opening tags are colored differently than the </> of a closing tag. | |
| 2932 This is on purpose! For opening tags the 'Function' color is used, while for | |
| 2933 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
| 2934 defined for you) | |
| 2935 | |
| 2936 Known tag names are colored the same way as statements in C. Unknown tag | |
| 2937 names are not colored which makes it easy to spot errors. | |
| 2938 | |
| 237 | 2939 Note that the same is true for argument (or attribute) names. Known attribute |
| 7 | 2940 names are colored differently than unknown ones. |
| 2941 | |
| 237 | 2942 Some SGML tags are used to change the rendering of text. The following tags |
| 7 | 2943 are recognized by the sgml.vim syntax coloring file and change the way normal |
| 2944 text is shown: <varname> <emphasis> <command> <function> <literal> | |
| 2945 <replaceable> <ulink> and <link>. | |
| 2946 | |
| 2947 If you want to change how such text is rendered, you must redefine the | |
| 2948 following syntax groups: | |
| 2949 | |
| 2950 - sgmlBold | |
| 2951 - sgmlBoldItalic | |
| 2952 - sgmlUnderline | |
| 2953 - sgmlItalic | |
| 2954 - sgmlLink for links | |
| 2955 | |
| 2956 To make this redefinition work you must redefine them all and define the | |
| 2957 following variable in your vimrc (this is due to the order in which the files | |
| 2958 are read during initialization) > | |
| 2959 let sgml_my_rendering=1 | |
| 2960 | |
| 2961 You can also disable this rendering by adding the following line to your | |
| 2962 vimrc file: > | |
| 2963 let sgml_no_rendering=1 | |
| 2964 | |

2972 shells such as bash, dash, posix, and the Korn shells. |
| 7 | 2973 |
| 2974 Vim attempts to determine which shell type is in use by specifying that | |
| 14421 | 2975 various filenames are of specific types, e.g.: > |
| 7 | 2976 |
| 2977 ksh : .kshrc* *.ksh | |
| 2978 bash: .bashrc* bashrc bash.bashrc .bash_profile* *.bash | |
| 2979 < | |
| 14421 | 2980 See $VIMRUNTIME/filetype.vim for the full list of patterns. If none of these |
| 2981 cases pertain, then the first line of the file is examined (ex. looking for | |
| 2982 /bin/sh /bin/ksh /bin/bash). If the first line specifies a shelltype, then | |
| 2983 that shelltype is used. However some files (ex. .profile) are known to be | |
| 2984 shell files but the type is not apparent. Furthermore, on many systems sh is | |
| 2985 symbolically linked to "bash" (Linux, Windows+cygwin) or "ksh" (Posix). | |

3014 then various syntax items (ie. HereDocuments and function bodies) become |
| 1624 | 3015 syntax-foldable (see |:syn-fold|). You also may add these together |
| 3016 to get multiple types of folding: > | |

| 3020 If you notice highlighting errors while scrolling backwards which are fixed | |
| 3021 when one redraws with CTRL-L, try setting the "sh_minlines" internal variable | |
| 7 | 3022 to a larger number. Example: > |
| 3023 | |
| 3024 let sh_minlines = 500 | |
| 3025 | |
| 3026 This will make syntax synchronization start 500 lines before the first | |
| 3027 displayed line. The default value is 200. The disadvantage of using a larger | |
| 3028 number is that redrawing can become slow. | |
| 3029 | |
| 3030 If you don't have much to synchronize on, displaying can be very slow. To | |
| 3031 reduce this, the "sh_maxlines" internal variable can be set. Example: > | |
| 3032 | |
| 3033 let sh_maxlines = 100 | |
| 3034 < | |
| 3035 The default is to use the twice sh_minlines. Set it to a smaller number to | |
| 3036 speed up displaying. The disadvantage is that highlight errors may appear. | |

3072 (AspenTech plant simulator) |
| 7 | 3073 |
| 3074 The Speedup syntax file has some options: | |
| 3075 | |
| 3076 - strict_subsections : If this variable is defined, only keywords for | |
| 3077 sections and subsections will be highlighted as statements but not | |
| 3078 other keywords (like WITHIN in the OPERATION section). | |
| 3079 | |
| 3080 - highlight_types : Definition of this variable causes stream types | |
| 3081 like temperature or pressure to be highlighted as Type, not as a | |
| 237 | 3082 plain Identifier. Included are the types that are usually found in |
| 7 | 3083 the DECLARE section; if you defined own types, you have to include |
| 3084 them in the syntax file. | |
| 3085 | |
| 3086 - oneline_comments : this value ranges from 1 to 3 and determines the | |
| 3087 highlighting of # style comments. | |
| 3088 | |
| 3089 oneline_comments = 1 : allow normal Speedup code after an even | |
| 3090 number of #s. | |
| 3091 | |
| 3092 oneline_comments = 2 : show code starting with the second # as | |
| 237 | 3093 error. This is the default setting. |
| 7 | 3094 |
| 3095 oneline_comments = 3 : show the whole line as error if it contains | |
| 3096 more than one #. | |
| 3097 | |
| 3098 Since especially OPERATION sections tend to become very large due to | |
| 237 | 3099 PRESETting variables, syncing may be critical. If your computer is |
| 7 | 3100 fast enough, you can increase minlines and/or maxlines near the end of |
| 3101 the syntax file. | |

| 3107 | |
| 3108 While there is an ANSI standard for SQL, most database engines add their own | |
| 3109 custom extensions. Vim currently supports the Oracle and Informix dialects of | |
| 3110 SQL. Vim assumes "*.sql" files are Oracle SQL by default. | |
| 3111 | |
| 3112 Vim currently has SQL support for a variety of different vendors via syntax | |
| 3113 scripts. You can change Vim's default from Oracle to any of the current SQL | |
| 3114 supported types. You can also easily alter the SQL dialect being used on a | |
| 3115 buffer by buffer basis. | |
| 3116 | |

| 3122 This covers the shell named "tcsh". It is a superset of csh. See |csh.vim| | |
| 3123 for how the filetype is detected. | |
| 3124 | |
| 3125 Tcsh does not allow \" in strings unless the "backslash_quote" shell variable | |
| 237 | 3126 is set. If you want VIM to assume that no backslash quote constructs exist add |
| 7 | 3127 this line to your .vimrc: > |
| 3128 | |
| 3129 :let tcsh_backslash_quote = 0 | |

| 3205 texMathZone. Although considerable effort has been made to have these zones | |
| 3206 terminate properly, zones delineated by $..$ and $$..$$ cannot be synchronized | |

| 3228 Finally, if syntax highlighting is still too slow, you may set > | |
| 3229 | |
| 3230 :let g:tex_fast= "" | |
| 3231 | |
| 3232 in your .vimrc. Used this way, the g:tex_fast variable causes the syntax | |
| 3233 highlighting script to avoid defining any regions and associated | |
| 3234 synchronization. The result will be much faster syntax highlighting; the | |
| 3235 price: you will no longer have as much highlighting or any syntax-based | |
| 3236 folding, and you will be missing syntax-based error checking. | |
| 3237 | |
| 3238 You may decide that some syntax is acceptable; you may use the following table | |
| 3239 selectively to enable just some syntax highlighting: > | |
| 3240 | |
| 3241 b : allow bold and italic syntax | |
| 3242 c : allow texComment syntax | |
| 3243 m : allow texMatcher syntax (ie. {...} and [...]) | |
| 3244 M : allow texMath syntax | |
| 3245 p : allow parts, chapter, section, etc syntax | |
| 3246 r : allow texRefZone syntax (nocite, bibliography, label, pageref, eqref) | |
| 3247 s : allow superscript/subscript regions | |
| 3248 S : allow texStyle syntax | |
| 3249 v : allow verbatim syntax | |
| 3250 V : allow texNewEnv and texNewCmd syntax | |
| 3251 < | |
| 3252 As an example, let g:tex_fast= "M" will allow math-associated highlighting | |
| 3253 but suppress all the other region-based syntax highlighting. | |

3257 Tex: Want To Highlight More Commands? ~ |
| 1125 | 3258 |
| 3259 LaTeX is a programmable language, and so there are thousands of packages full | |
| 3260 of specialized LaTeX commands, syntax, and fonts. If you're using such a | |
| 3261 package you'll often wish that the distributed syntax/tex.vim would support | |
| 3262 it. However, clearly this is impractical. So please consider using the | |
| 3263 techniques in |mysyntaxfile-add| to extend or modify the highlighting provided | |
| 3237 | 3264 by syntax/tex.vim. Please consider uploading any extensions that you write, |
| 3265 which typically would go in $HOME/after/syntax/tex/[pkgname].vim, to | |
| 3266 http://vim.sf.net/. | |
| 1125 | 3267 |

3275 Tex: Excessive Error Highlighting? ~ |
| 7 | 3276 |
| 3277 The <tex.vim> supports lexical error checking of various sorts. Thus, | |
| 3278 although the error checking is ofttimes very useful, it can indicate | |
| 3279 errors where none actually are. If this proves to be a problem for you, | |
| 3280 you may put in your <.vimrc> the following statement: > | |
| 4992 | 3281 let g:tex_no_error=1 |
| 477 | 3282 and all error checking by <syntax/tex.vim> will be suppressed. |

3285 Tex: Need a new Math Group? ~ |
| 7 | 3286 |
| 3287 If you want to include a new math group in your LaTeX, the following | |
| 3288 code shows you an example as to how you might do so: > | |
| 477 | 3289 call TexNewMathZone(sfx,mathzone,starform) |
| 3290 You'll want to provide the new math group with a unique suffix | |
| 3291 (currently, A-L and V-Z are taken by <syntax/tex.vim> itself). | |
| 3292 As an example, consider how eqnarray is set up by <syntax/tex.vim>: > | |
| 3293 call TexNewMathZone("D","eqnarray",1) | |
| 3294 You'll need to change "mathzone" to the name of your new math group, | |
| 3295 and then to the call to it in .vim/after/syntax/tex.vim. | |
| 3296 The "starform" variable, if true, implies that your new math group | |
| 3297 has a starred form (ie. eqnarray*). | |

3300 Tex: Starting a New Style? ~ |
| 7 | 3301 |
| 3302 One may use "\makeatletter" in *.tex files, thereby making the use of "@" in | |
| 3303 commands available. However, since the *.tex file doesn't have one of the | |
| 3304 following suffices: sty cls clo dtx ltx, the syntax highlighting will flag | |
| 3305 such use of @ as an error. To solve this: > | |
| 3306 | |
| 3307 :let b:tex_stylish = 1 | |
| 3308 :set ft=tex | |
| 3309 | |
| 3310 Putting "let g:tex_stylish=1" into your <.vimrc> will make <syntax/tex.vim> | |

3314 Tex: Taking Advantage of Conceal Mode~ |
| 2417 | 3315 |
| 2426 | 3316 If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a |
| 3317 number of character sequences can be translated into appropriate utf-8 glyphs, | |
| 3318 including various accented characters, Greek characters in MathZones, and | |
| 3319 superscripts and subscripts in MathZones. Not all characters can be made into | |
| 3320 superscripts or subscripts; the constraint is due to what utf-8 supports. | |
| 3321 In fact, only a few characters are supported as subscripts. | |
| 3322 | |
| 3323 One way to use this is to have vertically split windows (see |CTRL-W_v|); one | |
| 3324 with |'conceallevel'| at 0 and the other at 2; and both using |'scrollbind'|. | |

| 3346 Normally, LaTeX keywords support 0-9, a-z, A-z, and 192-255 only. Latex | |
| 3347 keywords don't support the underscore - except when in *.sty files. The | |
| 3348 syntax highlighting script handles this with the following logic: | |
| 3349 | |
| 3350 * If g:tex_stylish exists and is 1 | |
| 3351 then the file will be treated as a "sty" file, so the "_" | |

| 3364 | |
| 3365 See |tex-conceal| for how to enable concealed character replacement. | |
| 3366 | |
| 3367 See |g:tex_conceal| for selectively concealing accents, bold/italic, | |
| 3368 math, Greek, and superscripts/subscripts. | |
| 3369 | |
| 3370 One may exert fine control over which superscripts and subscripts one | |
| 3371 wants syntax-based concealment for (see |:syn-cchar|). Since not all | |
| 3372 fonts support all characters, one may override the | |
| 3373 concealed-replacement lists; by default these lists are given by: > | |
| 3374 | |
| 3375 let g:tex_superscripts= "[0-9a-zA-W.,:;+-<>/()=]" | |
| 3376 let g:tex_subscripts= "[0-9aehijklmnoprstuvx,+-/().]" | |
| 3377 < | |
| 3378 For example, I use Luxi Mono Bold; it doesn't support subscript | |
| 3379 characters for "hklmnpst", so I put > | |
| 3380 let g:tex_subscripts= "[0-9aeijoruvx,+-/().]" | |
| 3381 < in ~/.vim/ftplugin/tex/tex.vim in order to avoid having inscrutable | |
| 3382 utf-8 glyphs appear. | |

3439 is a difficult language to highlight correctly. A way to suppress error |
| 1624 | 3440 highlighting is to put the following line in your |vimrc|: > |

| 7 | 3447 |
| 3448 The syntax of XF86Config file differs in XFree86 v3.x and v4.x. Both | |
| 3449 variants are supported. Automatic detection is used, but is far from perfect. | |
| 3450 You may need to specify the version manually. Set the variable | |
| 3451 xf86conf_xfree86_version to 3 or 4 according to your XFree86 version in | |
| 3452 your .vimrc. Example: > | |
| 3453 :let xf86conf_xfree86_version=3 | |
| 3454 When using a mix of versions, set the b:xf86conf_xfree86_version variable. | |
| 3455 | |
| 3456 Note that spaces and underscores in option names are not supported. Use | |
| 3457 "SyncOnGreen" instead of "__s yn con gr_e_e_n" if you want the option name | |
| 3458 highlighted. | |

| 3465 | |
| 3466 :let g:xml_namespace_transparent=1 | |
| 3467 < | |
| 3468 *xml-folding* | |
| 3469 The xml syntax file provides syntax |folding| (see |:syn-fold|) between | |
| 237 | 3470 start and end tags. This can be turned on by > |
| 7 | 3471 |
| 3472 :let g:xml_syntax_folding = 1 | |
| 3473 :set foldmethod=syntax | |
| 3474 | |
| 3475 Note: syntax folding might slow down syntax highlighting significantly, | |
| 3476 especially for large files. | |
| 3477 | |
| 3478 | |
| 501 | 3479 X Pixmaps (XPM) *xpm.vim* *ft-xpm-syntax* |
| 7 | 3480 |
| 3481 xpm.vim creates its syntax items dynamically based upon the contents of the | |
| 3482 XPM file. Thus if you make changes e.g. in the color specification strings, | |
| 3483 you have to source it again e.g. with ":set syn=xpm". | |
| 3484 | |
| 3485 To copy a pixel with one of the colors, yank a "pixel" with "yl" and insert it | |
| 3486 somewhere else with "P". | |
| 3487 | |
| 3488 Do you want to draw with the mouse? Try the following: > | |
| 3489 :function! GetPixel() | |
| 823 | 3490 : let c = getline(".")[col(".") - 1] |
| 7 | 3491 : echo c |
| 3492 : exe "noremap <LeftMouse> <LeftMouse>r".c | |
| 3493 : exe "noremap <LeftDrag> <LeftMouse>r".c | |
| 3494 :endfunction | |
| 3495 :noremap <RightMouse> <LeftMouse>:call GetPixel()<CR> | |
| 3496 :set guicursor=n:hor20 " to see the color beneath the cursor | |
| 3497 This turns the right button into a pipette and the left button into a pen. | |
| 3498 It will work with XPM files that have one character per pixel only and you | |
| 3499 must not click outside of the pixel strings, but feel free to improve it. | |
| 3500 | |
| 3501 It will look much better with a font in a quadratic cell size, e.g. for X: > | |
| 3502 :set guifont=-*-clean-medium-r-*-*-8-*-*-*-*-80-* | |
| 3503 | |

| 3505 YAML *yaml.vim* *ft-yaml-syntax* | |
| 3506 | |
| 3507 *g:yaml_schema* *b:yaml_schema* | |
| 3508 A YAML schema is a combination of a set of tags and a mechanism for resolving | |
| 3509 non-specific tags. For user this means that YAML parser may, depending on | |
| 3510 plain scalar contents, treat plain scalar (which can actually be only string | |
| 3511 and nothing else) as a value of the other type: null, boolean, floating-point, | |
| 3512 integer. `g:yaml_schema` option determines according to which schema values | |
| 3513 will be highlighted specially. Supported schemas are | |
| 3514 | |
| 3515 Schema Description ~ | |
| 3516 failsafe No additional highlighting. | |
| 3517 json Supports JSON-style numbers, booleans and null. | |
| 3518 core Supports more number, boolean and null styles. | |
| 3519 pyyaml In addition to core schema supports highlighting timestamps, | |
| 3520 but there are some differences in what is recognized as | |
| 3521 numbers and many additional boolean values not present in core | |
| 3522 schema. | |
| 3523 | |
| 3524 Default schema is `core`. | |
| 3525 | |
| 3526 Note that schemas are not actually limited to plain scalars, but this is the | |
| 3527 only difference between schemas defined in YAML specification and the only | |
| 3528 difference defined in the syntax file. | |

| 7 | 3537 ============================================================================== |
| 15194 | 3538 6. Defining a syntax *:syn-define* *E410* |
| 7 | 3539 |
| 3540 Vim understands three types of syntax items: | |
| 3541 | |
| 419 | 3542 1. Keyword |
| 7 | 3543 It can only contain keyword characters, according to the 'iskeyword' |
| 3544 option. It cannot contain other syntax items. It will only match with a | |
| 3545 complete word (there are no keyword characters before or after the match). | |
| 3546 The keyword "if" would match in "if(a=b)", but not in "ifdef x", because | |
| 3547 "(" is not a keyword character and "d" is. | |
| 3548 | |
| 419 | 3549 2. Match |
| 7 | 3550 This is a match with a single regexp pattern. |
| 3551 | |
| 419 | 3552 3. Region |
| 7 | 3553 This starts at a match of the "start" regexp pattern and ends with a match |
| 3554 with the "end" regexp pattern. Any other text can appear in between. A | |
| 3555 "skip" regexp pattern can be used to avoid matching the "end" pattern. | |
| 3556 | |
| 3557 Several syntax ITEMs can be put into one syntax GROUP. For a syntax group | |
| 3558 you can give highlighting attributes. For example, you could have an item | |
| 3559 to define a "/* .. */" comment and another one that defines a "// .." comment, | |
| 3560 and put them both in the "Comment" group. You can then specify that a | |
| 3561 "Comment" will be in bold font and have a blue color. You are free to make | |
| 3562 one highlight group for one syntax item, or put all items into one group. | |
| 3563 This depends on how you want to specify your highlighting attributes. Putting | |
| 3564 each item in its own group results in having to specify the highlighting | |
| 3565 for a lot of groups. | |
| 3566 | |
| 3567 Note that a syntax group and a highlight group are similar. For a highlight | |
| 3568 group you will have given highlight attributes. These attributes will be used | |
| 3569 for the syntax group with the same name. | |
| 3570 | |
| 3571 In case more than one item matches at the same position, the one that was | |
| 3572 defined LAST wins. Thus you can override previously defined syntax items by | |
| 3573 using an item that matches the same text. But a keyword always goes before a | |
| 3574 match or region. And a keyword with matching case always goes before a | |
| 3575 keyword with ignoring case. | |
| 3576 | |
| 3577 | |
| 3578 PRIORITY *:syn-priority* | |
| 3579 | |
| 3580 When several syntax items may match, these rules are used: | |
| 3581 | |
| 3582 1. When multiple Match or Region items start in the same position, the item | |
| 3583 defined last has priority. | |
| 3584 2. A Keyword has priority over Match and Region items. | |
| 3585 3. An item that starts in an earlier position has priority over items that | |
| 3586 start in later positions. | |
| 3587 | |
| 3588 | |
| 3589 DEFINING CASE *:syn-case* *E390* | |
| 3590 | |
| 419 | 3591 :sy[ntax] case [match | ignore] |
| 7 | 3592 This defines if the following ":syntax" commands will work with |
| 3593 matching case, when using "match", or with ignoring case, when using | |
| 3594 "ignore". Note that any items before this are not affected, and all | |
| 3595 items until the next ":syntax case" command are affected. | |
| 3596 | |
| 10734 | 3597 :sy[ntax] case |
| 3598 Show either "syntax case match" or "syntax case ignore" (translated). | |
| 7 | 3599 |
| 419 | 3600 SPELL CHECKING *:syn-spell* |
| 3601 | |
| 3602 :sy[ntax] spell [toplevel | notoplevel | default] | |
| 3603 This defines where spell checking is to be done for text that is not | |
| 3604 in a syntax item: | |
| 3605 | |
| 3606 toplevel: Text is spell checked. | |
| 3607 notoplevel: Text is not spell checked. | |
| 3608 default: When there is a @Spell cluster no spell checking. | |
| 3609 | |
| 3610 For text in syntax items use the @Spell and @NoSpell clusters | |
| 3611 |spell-syntax|. When there is no @Spell and no @NoSpell cluster then | |
| 3612 spell checking is done for "default" and "toplevel". | |
| 3613 | |
| 3614 To activate spell checking the 'spell' option must be set. | |
| 3615 | |
| 10734 | 3616 :sy[ntax] spell |
| 3617 Show either "syntax spell toplevel", "syntax spell notoplevel" or | |
| 3618 "syntax spell default" (translated). | |

| 3653 | |
| 3654 {group-name} Is a syntax group name such as "Comment". | |
| 3655 [{options}] See |:syn-arguments| below. | |

3667 < *E789* *E890* |
| 7 | 3668 When you have a keyword with an optional tail, like Ex commands in |
| 3669 Vim, you can put the optional characters inside [], to define all the | |
| 3670 variations at once: > | |
| 3671 :syntax keyword vimCommand ab[breviate] n[ext] | |
| 3672 < | |
| 3673 Don't forget that a keyword can only be recognized if all the | |
| 3674 characters are included in the 'iskeyword' option. If one character | |
| 3675 isn't, the keyword will never be recognized. | |
| 3676 Multi-byte characters can also be used. These do not have to be in | |
| 3677 'iskeyword'. | |

3678 See |:syn-iskeyword| for defining syntax specific iskeyword settings. |
| 7 | 3679 |
| 3680 A keyword always has higher priority than a match or region, the | |
| 3681 keyword is used if more than one item matches. Keywords do not nest | |
| 3682 and a keyword can't contain anything else. | |
| 3683 | |
| 3684 Note that when you have a keyword that is the same as an option (even | |
| 3685 one that isn't allowed here), you can not use it. Use a match | |
| 3686 instead. | |
| 3687 | |
| 3688 The maximum length of a keyword is 80 characters. | |
| 3689 | |
| 3690 The same keyword can be defined multiple times, when its containment | |
| 3691 differs. For example, you can define the keyword once not contained | |
| 3692 and use one highlight group, and once contained, and use a different | |
| 237 | 3693 highlight group. Example: > |
| 7 | 3694 :syn keyword vimCommand tag |
| 3695 :syn keyword vimSetting contained tag | |
| 3696 < When finding "tag" outside of any syntax item, the "vimCommand" | |
| 3697 highlight group is used. When finding "tag" in a syntax item that | |
| 3698 contains "vimSetting", the "vimSetting" group is used. | |

3718 |:syn-keepend|. |
| 7 | 3719 {pattern} The search pattern that defines the match. |
| 3720 See |:syn-pattern| below. | |
| 3721 Note that the pattern may match more than one | |
| 3722 line, which makes the match depend on where | |
| 3723 Vim starts searching for the pattern. You | |
| 3724 need to make sure syncing takes care of this. | |
| 3725 | |
| 3726 Example (match a character constant): > | |
| 3727 :syntax match Character /'.'/hs=s+1,he=e-1 | |
| 3728 < | |
| 3729 | |
| 3730 DEFINING REGIONS *:syn-region* *:syn-start* *:syn-skip* *:syn-end* | |
| 3731 *E398* *E399* | |
| 3732 :sy[ntax] region {group-name} [{options}] | |
| 3733 [matchgroup={group-name}] | |
| 3734 [keepend] | |
| 3735 [extend] | |
| 3736 [excludenl] | |
| 3737 start={start_pattern} .. | |
| 3738 [skip={skip_pattern}] | |
| 3739 end={end_pattern} .. | |
| 3740 [{options}] | |
| 3741 | |
| 3742 This defines one region. It may span several lines. | |
| 3743 | |
| 3744 {group-name} A syntax group name such as "Comment". | |
| 3745 [{options}] See |:syn-arguments| below. | |
| 3746 [matchgroup={group-name}] The syntax group to use for the following | |
| 3747 start or end pattern matches only. Not used | |
| 3748 for the text in between the matched start and | |
| 3749 end patterns. Use NONE to reset to not using | |
| 3750 a different group for the start or end match. | |
| 3751 See |:syn-matchgroup|. | |
| 3752 keepend Don't allow contained matches to go past a | |
| 3753 match with the end pattern. See | |
| 3754 |:syn-keepend|. | |
| 3755 extend Override a "keepend" for an item this region | |
| 237 | 3756 is contained in. See |:syn-extend|. |
| 7 | 3757 excludenl Don't make a pattern with the end-of-line "$" |
| 3758 extend a containing match or item. Only | |
| 3759 useful for end patterns. Must be given before | |
| 3760 the patterns it applies to. |:syn-excludenl| | |
| 3761 start={start_pattern} The search pattern that defines the start of | |
| 3762 the region. See |:syn-pattern| below. | |
| 3763 skip={skip_pattern} The search pattern that defines text inside | |
| 3764 the region where not to look for the end | |
| 3765 pattern. See |:syn-pattern| below. | |
| 3766 end={end_pattern} The search pattern that defines the end of | |
| 3767 the region. See |:syn-pattern| below. | |
| 3768 | |
| 3769 Example: > | |
| 3770 :syntax region String start=+"+ skip=+\\"+ end=+"+ | |
| 3771 < | |
| 3772 The start/skip/end patterns and the options can be given in any order. | |
| 3773 There can be zero or one skip pattern. There must be one or more | |
| 3774 start and end patterns. This means that you can omit the skip | |
| 3775 pattern, but you must give at least one start and one end pattern. It | |
| 3776 is allowed to have white space before and after the equal sign | |
| 3777 (although it mostly looks better without white space). | |
| 3778 | |
| 3779 When more than one start pattern is given, a match with one of these | |
| 3780 is sufficient. This means there is an OR relation between the start | |
| 3781 patterns. The last one that matches is used. The same is true for | |
| 3782 the end patterns. | |
| 3783 | |
| 3784 The search for the end pattern starts right after the start pattern. | |
| 3785 Offsets are not used for this. This implies that the match for the | |
| 3786 end pattern will never overlap with the start pattern. | |
| 3787 | |
| 3788 The skip and end pattern can match across line breaks, but since the | |
| 3789 search for the pattern can start in any line it often does not do what | |
| 3790 you want. The skip pattern doesn't avoid a match of an end pattern in | |
| 3791 the next line. Use single-line patterns to avoid trouble. | |
| 3792 | |
| 3793 Note: The decision to start a region is only based on a matching start | |
| 3794 pattern. There is no check for a matching end pattern. This does NOT | |
| 3795 work: > | |
| 3796 :syn region First start="(" end=":" | |
| 3797 :syn region Second start="(" end=";" | |
| 3798 < The Second always matches before the First (last defined pattern has | |
| 3799 higher priority). The Second region then continues until the next | |
| 3800 ';', no matter if there is a ':' before it. Using a match does work: > | |
| 3801 :syn match First "(\_.\{-}:" | |
| 3802 :syn match Second "(\_.\{-};" | |
| 3803 < This pattern matches any character or line break with "\_." and | |
| 3804 repeats that with "\{-}" (repeat as few as possible). | |
| 3805 | |
| 3806 *:syn-keepend* | |
| 3807 By default, a contained match can obscure a match for the end pattern. | |
| 3808 This is useful for nesting. For example, a region that starts with | |
| 3809 "{" and ends with "}", can contain another region. An encountered "}" | |
| 3810 will then end the contained region, but not the outer region: | |
| 3811 { starts outer "{}" region | |
| 3812 { starts contained "{}" region | |
| 3813 } ends contained "{}" region | |
| 3814 } ends outer "{} region | |
| 3815 If you don't want this, the "keepend" argument will make the matching | |
| 3816 of an end pattern of the outer region also end any contained item. | |
| 3817 This makes it impossible to nest the same region, but allows for | |
| 3818 contained items to highlight parts of the end pattern, without causing | |
| 3819 that to skip the match with the end pattern. Example: > | |
| 3820 :syn match vimComment +"[^"]\+$+ | |
| 3821 :syn region vimCommand start="set" end="$" contains=vimComment keepend | |
| 3822 < The "keepend" makes the vimCommand always end at the end of the line, | |
| 3823 even though the contained vimComment includes a match with the <EOL>. | |
| 3824 | |
| 3825 When "keepend" is not used, a match with an end pattern is retried | |
| 3826 after each contained match. When "keepend" is included, the first | |
| 3827 encountered match with an end pattern is used, truncating any | |
| 3828 contained matches. | |
| 3829 *:syn-extend* | |
| 3830 The "keepend" behavior can be changed by using the "extend" argument. | |
| 3831 When an item with "extend" is contained in an item that uses | |
| 3832 "keepend", the "keepend" is ignored and the containing region will be | |
| 3833 extended. | |
| 3834 This can be used to have some contained items extend a region while | |
| 3835 others don't. Example: > | |
| 3836 | |
| 3837 :syn region htmlRef start=+<a>+ end=+</a>+ keepend contains=htmlItem,htmlScript | |
| 3838 :syn match htmlItem +<[^>]*>+ contained | |
| 3839 :syn region htmlScript start=+<script+ end=+</script[^>]*>+ contained extend | |
| 3840 | |
| 3841 < Here the htmlItem item does not make the htmlRef item continue | |
| 3842 further, it is only used to highlight the <> items. The htmlScript | |
| 3843 item does extend the htmlRef item. | |
| 3844 | |
| 3845 Another example: > | |
| 3846 :syn region xmlFold start="<a>" end="</a>" fold transparent keepend extend | |
| 3847 < This defines a region with "keepend", so that its end cannot be | |
| 3848 changed by contained items, like when the "</a>" is matched to | |
| 3849 highlight it differently. But when the xmlFold region is nested (it | |
| 3850 includes itself), the "extend" applies, so that the "</a>" of a nested | |
| 3851 region only ends that region, and not the one it is contained in. | |
| 3852 | |
| 3853 *:syn-excludenl* | |
| 3854 When a pattern for a match or end pattern of a region includes a '$' | |
| 3855 to match the end-of-line, it will make a region item that it is | |
| 3856 contained in continue on the next line. For example, a match with | |
| 3857 "\\$" (backslash at the end of the line) can make a region continue | |
| 3858 that would normally stop at the end of the line. This is the default | |
| 3859 behavior. If this is not wanted, there are two ways to avoid it: | |
| 3860 1. Use "keepend" for the containing item. This will keep all | |
| 3861 contained matches from extending the match or region. It can be | |
| 3862 used when all contained items must not extend the containing item. | |
| 3863 2. Use "excludenl" in the contained item. This will keep that match | |
| 3864 from extending the containing match or region. It can be used if | |
| 3865 only some contained items must not extend the containing item. | |
| 3866 "excludenl" must be given before the pattern it applies to. | |
| 3867 | |
| 3868 *:syn-matchgroup* | |
| 3869 "matchgroup" can be used to highlight the start and/or end pattern | |
| 3870 differently than the body of the region. Example: > | |
| 3871 :syntax region String matchgroup=Quote start=+"+ skip=+\\"+ end=+"+ | |
| 3872 < This will highlight the quotes with the "Quote" group, and the text in | |
| 3873 between with the "String" group. | |
| 3874 The "matchgroup" is used for all start and end patterns that follow, | |
| 3875 until the next "matchgroup". Use "matchgroup=NONE" to go back to not | |
| 3876 using a matchgroup. | |
| 3877 | |
| 3878 In a start or end pattern that is highlighted with "matchgroup" the | |
| 3879 contained items of the region are not used. This can be used to avoid | |
| 3880 that a contained item matches in the start or end pattern match. When | |
| 3881 using "transparent", this does not apply to a start or end pattern | |
| 3882 match that is highlighted with "matchgroup". | |
| 3883 | |
| 3884 Here is an example, which highlights three levels of parentheses in | |
| 3885 different colors: > | |
| 3886 :sy region par1 matchgroup=par1 start=/(/ end=/)/ contains=par2 | |
| 3887 :sy region par2 matchgroup=par2 start=/(/ end=/)/ contains=par3 contained | |
| 3888 :sy region par3 matchgroup=par3 start=/(/ end=/)/ contains=par1 contained | |
| 3889 :hi par1 ctermfg=red guifg=red | |
| 3890 :hi par2 ctermfg=blue guifg=blue | |
| 3891 :hi par3 ctermfg=darkgreen guifg=darkgreen | |

3947 See |hl-Conceal| for highlighting. |

| 3949 contained *:syn-contained* | |
| 3950 | |
| 3951 When the "contained" argument is given, this item will not be recognized at | |
| 3952 the top level, but only when it is mentioned in the "contains" field of | |
| 3953 another match. Example: > | |
| 3954 :syntax keyword Todo TODO contained | |
| 3955 :syntax match Comment "//.*" contains=Todo | |
| 3956 | |
| 3957 | |
| 3958 display *:syn-display* | |
| 3959 | |
| 3960 If the "display" argument is given, this item will be skipped when the | |
| 3961 detected highlighting will not be displayed. This will speed up highlighting, | |
| 3962 by skipping this item when only finding the syntax state for the text that is | |
| 3963 to be displayed. | |
| 3964 | |
| 3965 Generally, you can use "display" for match and region items that meet these | |
| 3966 conditions: | |
| 3967 - The item does not continue past the end of a line. Example for C: A region | |
| 3968 for a "/*" comment can't contain "display", because it continues on the next | |
| 3969 line. | |
| 3970 - The item does not contain items that continue past the end of the line or | |
| 3971 make it continue on the next line. | |
| 3972 - The item does not change the size of any item it is contained in. Example | |
| 3973 for C: A match with "\\$" in a preprocessor match can't have "display", | |
| 3974 because it may make that preprocessor match shorter. | |
| 3975 - The item does not allow other items to match that didn't match otherwise, | |
| 3976 and that item may extend the match too far. Example for C: A match for a | |
| 3977 "//" comment can't use "display", because a "/*" inside that comment would | |
| 3978 match then and start a comment which extends past the end of the line. | |
| 3979 | |
| 3980 Examples, for the C language, where "display" can be used: | |
| 3981 - match with a number | |
| 3982 - match with a label | |
| 3983 | |
| 3984 | |
| 3985 transparent *:syn-transparent* | |
| 3986 | |
| 3987 If the "transparent" argument is given, this item will not be highlighted | |
| 3988 itself, but will take the highlighting of the item it is contained in. This | |
| 3989 is useful for syntax items that don't need any highlighting but are used | |
| 3990 only to skip over a part of the text. | |
| 3991 | |
| 3992 The "contains=" argument is also inherited from the item it is contained in, | |
| 3993 unless a "contains" argument is given for the transparent item itself. To | |
| 3994 avoid that unwanted items are contained, use "contains=NONE". Example, which | |
| 3995 highlights words in strings, but makes an exception for "vim": > | |
| 3996 :syn match myString /'[^']*'/ contains=myWord,myVim | |
| 3997 :syn match myWord /\<[a-z]*\>/ contained | |
| 3998 :syn match myVim /\<vim\>/ transparent contained contains=NONE | |
| 3999 :hi link myString String | |
| 4000 :hi link myWord Comment | |
| 4001 Since the "myVim" match comes after "myWord" it is the preferred match (last | |
| 4002 match in the same position overrules an earlier one). The "transparent" | |
| 4003 argument makes the "myVim" match use the same highlighting as "myString". But | |
| 4004 it does not contain anything. If the "contains=NONE" argument would be left | |
| 4005 out, then "myVim" would use the contains argument from myString and allow | |
| 4006 "myWord" to be contained, which will be highlighted as a Constant. This | |
| 4007 happens because a contained match doesn't match inside itself in the same | |
| 4008 position, thus the "myVim" match doesn't overrule the "myWord" match here. | |
| 4009 | |
| 4010 When you look at the colored text, it is like looking at layers of contained | |
| 4011 items. The contained item is on top of the item it is contained in, thus you | |
| 4012 see the contained item. When a contained item is transparent, you can look | |
| 4013 through, thus you see the item it is contained in. In a picture: | |
| 4014 | |
| 4015 look from here | |
| 4016 | |
| 4017 | | | | | | | |
| 4018 V V V V V V | |
| 4019 | |
| 4020 xxxx yyy more contained items | |
| 4021 .................... contained item (transparent) | |
| 4022 ============================= first item | |
| 4023 | |
| 4024 The 'x', 'y' and '=' represent a highlighted syntax item. The '.' represent a | |
| 4025 transparent group. | |
| 4026 | |
| 4027 What you see is: | |
| 4028 | |
| 4029 =======xxxx=======yyy======== | |
| 4030 | |
| 4031 Thus you look through the transparent "....". | |
| 4032 | |
| 4033 | |
| 4034 oneline *:syn-oneline* | |
| 4035 | |
| 4036 The "oneline" argument indicates that the region does not cross a line | |
| 4037 boundary. It must match completely in the current line. However, when the | |
| 4038 region has a contained item that does cross a line boundary, it continues on | |
| 4039 the next line anyway. A contained item can be used to recognize a line | |
| 4040 continuation pattern. But the "end" pattern must still match in the first | |
| 4041 line, otherwise the region doesn't even start. | |
| 4042 | |
| 4043 When the start pattern includes a "\n" to match an end-of-line, the end | |
| 4044 pattern must be found in the same line as where the start pattern ends. The | |
| 4045 end pattern may also include an end-of-line. Thus the "oneline" argument | |
| 4046 means that the end of the start pattern and the start of the end pattern must | |
| 4047 be within one line. This can't be changed by a skip pattern that matches a | |
| 4048 line break. | |
| 4049 | |
| 4050 | |
| 4051 fold *:syn-fold* | |
| 4052 | |
| 1624 | 4053 The "fold" argument makes the fold level increase by one for this item. |
| 7 | 4054 Example: > |
| 4055 :syn region myFold start="{" end="}" transparent fold | |
| 4056 :syn sync fromstart | |
| 4057 :set foldmethod=syntax | |
| 4058 This will make each {} block form one fold. | |
| 4059 | |
| 4060 The fold will start on the line where the item starts, and end where the item | |
| 4061 ends. If the start and end are within the same line, there is no fold. | |
| 4062 The 'foldnestmax' option limits the nesting of syntax folds. | |
| 4063 {not available when Vim was compiled without |+folding| feature} | |
| 4064 | |
| 4065 | |
| 4066 *:syn-contains* *E405* *E406* *E407* *E408* *E409* | |
| 6259 | 4067 contains={group-name},.. |
| 7 | 4068 |
| 4069 The "contains" argument is followed by a list of syntax group names. These | |
| 4070 groups will be allowed to begin inside the item (they may extend past the | |
| 4071 containing group's end). This allows for recursive nesting of matches and | |
| 4072 regions. If there is no "contains" argument, no groups will be contained in | |
| 4073 this item. The group names do not need to be defined before they can be used | |
| 4074 here. | |
| 4075 | |
| 4076 contains=ALL | |
| 4077 If the only item in the contains list is "ALL", then all | |
| 4078 groups will be accepted inside the item. | |
| 4079 | |
| 4080 contains=ALLBUT,{group-name},.. | |
| 4081 If the first item in the contains list is "ALLBUT", then all | |
| 4082 groups will be accepted inside the item, except the ones that | |
| 4083 are listed. Example: > | |
| 4084 :syntax region Block start="{" end="}" ... contains=ALLBUT,Function | |
| 4085 | |
| 4086 contains=TOP | |
| 4087 If the first item in the contains list is "TOP", then all | |
| 4088 groups will be accepted that don't have the "contained" | |
| 4089 argument. | |
| 4090 contains=TOP,{group-name},.. | |
| 4091 Like "TOP", but excluding the groups that are listed. | |
| 4092 | |
| 4093 contains=CONTAINED | |
| 4094 If the first item in the contains list is "CONTAINED", then | |
| 4095 all groups will be accepted that have the "contained" | |
| 4096 argument. | |
| 4097 contains=CONTAINED,{group-name},.. | |
| 4098 Like "CONTAINED", but excluding the groups that are | |
| 4099 listed. | |
| 4100 | |
| 4101 | |
| 4102 The {group-name} in the "contains" list can be a pattern. All group names | |
| 4103 that match the pattern will be included (or excluded, if "ALLBUT" is used). | |
| 4104 The pattern cannot contain white space or a ','. Example: > | |
| 4105 ... contains=Comment.*,Keyw[0-3] | |
| 4106 The matching will be done at moment the syntax command is executed. Groups | |
| 4107 that are defined later will not be matched. Also, if the current syntax | |
| 4108 command defines a new group, it is not matched. Be careful: When putting | |
| 4109 syntax commands in a file you can't rely on groups NOT being defined, because | |
| 4110 the file may have been sourced before, and ":syn clear" doesn't remove the | |
| 4111 group names. | |
| 4112 | |
| 4113 The contained groups will also match in the start and end patterns of a | |
| 4114 region. If this is not wanted, the "matchgroup" argument can be used | |
| 4115 |:syn-matchgroup|. The "ms=" and "me=" offsets can be used to change the | |
| 4116 region where contained items do match. Note that this may also limit the | |
| 4117 area that is highlighted | |
| 4118 | |
| 4119 | |
| 6259 | 4120 containedin={group-name}... *:syn-containedin* |
| 7 | 4121 |
| 4122 The "containedin" argument is followed by a list of syntax group names. The | |
| 4123 item will be allowed to begin inside these groups. This works as if the | |
| 4124 containing item has a "contains=" argument that includes this item. | |
| 4125 | |
| 6259 | 4126 The {group-name}... can be used just like for "contains", as explained above. |
| 7 | 4127 |
| 4128 This is useful when adding a syntax item afterwards. An item can be told to | |
| 4129 be included inside an already existing item, without changing the definition | |
| 4130 of that item. For example, to highlight a word in a C comment after loading | |
| 4131 the C syntax: > | |
| 4132 :syn keyword myword HELP containedin=cComment contained | |
| 4133 Note that "contained" is also used, to avoid that the item matches at the top | |
| 4134 level. | |
| 4135 | |
| 4136 Matches for "containedin" are added to the other places where the item can | |
| 4137 appear. A "contains" argument may also be added as usual. Don't forget that | |
| 4138 keywords never contain another item, thus adding them to "containedin" won't | |
| 4139 work. | |
| 4140 | |
| 4141 | |
| 6259 | 4142 nextgroup={group-name},.. *:syn-nextgroup* |
| 7 | 4143 |
| 4144 The "nextgroup" argument is followed by a list of syntax group names, | |
| 4145 separated by commas (just like with "contains", so you can also use patterns). | |
| 4146 | |
| 4147 If the "nextgroup" argument is given, the mentioned syntax groups will be | |
| 4148 tried for a match, after the match or region ends. If none of the groups have | |
| 4149 a match, highlighting continues normally. If there is a match, this group | |
| 4150 will be used, even when it is not mentioned in the "contains" field of the | |
| 4151 current group. This is like giving the mentioned group priority over all | |
| 4152 other groups. Example: > | |
| 4153 :syntax match ccFoobar "Foo.\{-}Bar" contains=ccFoo | |
| 4154 :syntax match ccFoo "Foo" contained nextgroup=ccFiller | |
| 4155 :syntax region ccFiller start="." matchgroup=ccBar end="Bar" contained | |
| 4156 | |
| 4157 This will highlight "Foo" and "Bar" differently, and only when there is a | |
| 4158 "Bar" after "Foo". In the text line below, "f" shows where ccFoo is used for | |
| 4159 highlighting, and "bbb" where ccBar is used. > | |
| 4160 | |
| 4161 Foo asdfasd Bar asdf Foo asdf Bar asdf | |
| 4162 fff bbb fff bbb | |
| 4163 | |
| 4164 Note the use of ".\{-}" to skip as little as possible until the next Bar. | |
| 4165 when ".*" would be used, the "asdf" in between "Bar" and "Foo" would be | |
| 4166 highlighted according to the "ccFoobar" group, because the ccFooBar match | |
| 4167 would include the first "Foo" and the last "Bar" in the line (see |pattern|). | |
| 4168 | |
| 4169 | |
| 4170 skipwhite *:syn-skipwhite* | |
| 4171 skipnl *:syn-skipnl* | |
| 4172 skipempty *:syn-skipempty* | |
| 4173 | |
| 4174 These arguments are only used in combination with "nextgroup". They can be | |
| 4175 used to allow the next group to match after skipping some text: | |
| 1275 | 4176 skipwhite skip over space and tab characters |
| 7 | 4177 skipnl skip over the end of a line |
| 4178 skipempty skip over empty lines (implies a "skipnl") | |
| 4179 | |
| 4180 When "skipwhite" is present, the white space is only skipped if there is no | |
| 4181 next group that matches the white space. | |
| 4182 | |
| 4183 When "skipnl" is present, the match with nextgroup may be found in the next | |
| 4184 line. This only happens when the current item ends at the end of the current | |
| 4185 line! When "skipnl" is not present, the nextgroup will only be found after | |
| 4186 the current item in the same line. | |
| 4187 | |
| 4188 When skipping text while looking for a next group, the matches for other | |
| 4189 groups are ignored. Only when no next group matches, other items are tried | |
| 4190 for a match again. This means that matching a next group and skipping white | |
| 4191 space and <EOL>s has a higher priority than other items. | |
| 4192 | |
| 4193 Example: > | |
| 4194 :syn match ifstart "\<if.*" nextgroup=ifline skipwhite skipempty | |
| 4195 :syn match ifline "[^ \t].*" nextgroup=ifline skipwhite skipempty contained | |
| 4196 :syn match ifline "endif" contained | |
| 4197 Note that the "[^ \t].*" match matches all non-white text. Thus it would also | |
| 4198 match "endif". Therefore the "endif" match is put last, so that it takes | |
| 4199 precedence. | |
| 4200 Note that this example doesn't work for nested "if"s. You need to add | |
| 4201 "contains" arguments to make that work (omitted for simplicity of the | |
| 4202 example). | |

| 15194 | 4218 8. Syntax patterns *:syn-pattern* *E401* *E402* |
| 7 | 4219 |
| 4220 In the syntax commands, a pattern must be surrounded by two identical | |
| 4221 characters. This is like it works for the ":s" command. The most common to | |
| 4222 use is the double quote. But if the pattern contains a double quote, you can | |
| 4223 use another character that is not used in the pattern. Examples: > | |
| 4224 :syntax region Comment start="/\*" end="\*/" | |
| 4225 :syntax region String start=+"+ end=+"+ skip=+\\"+ | |
| 4226 | |
| 4227 See |pattern| for the explanation of what a pattern is. Syntax patterns are | |
| 1624 | 4228 always interpreted like the 'magic' option is set, no matter what the actual |
| 7 | 4229 value of 'magic' is. And the patterns are interpreted like the 'l' flag is |
| 4230 not included in 'cpoptions'. This was done to make syntax files portable and | |
| 4231 independent of 'compatible' and 'magic' settings. | |
| 4232 | |
| 4233 Try to avoid patterns that can match an empty string, such as "[a-z]*". | |
| 4234 This slows down the highlighting a lot, because it matches everywhere. | |
| 4235 | |
| 4236 *:syn-pattern-offset* | |
| 4237 The pattern can be followed by a character offset. This can be used to | |
| 4238 change the highlighted part, and to change the text area included in the | |
| 4239 match or region (which only matters when trying to match other items). Both | |
| 4240 are relative to the matched pattern. The character offset for a skip | |
| 4241 pattern can be used to tell where to continue looking for an end pattern. | |
| 4242 | |
| 4243 The offset takes the form of "{what}={offset}" | |
| 4244 The {what} can be one of seven strings: | |
| 4245 | |
| 4246 ms Match Start offset for the start of the matched text | |
| 4247 me Match End offset for the end of the matched text | |
| 4248 hs Highlight Start offset for where the highlighting starts | |
| 4249 he Highlight End offset for where the highlighting ends | |
| 4250 rs Region Start offset for where the body of a region starts | |
| 4251 re Region End offset for where the body of a region ends | |
| 4252 lc Leading Context offset past "leading context" of pattern | |
| 4253 | |
| 4254 The {offset} can be: | |
| 4255 | |
| 4256 s start of the matched pattern | |
| 4257 s+{nr} start of the matched pattern plus {nr} chars to the right | |
| 4258 s-{nr} start of the matched pattern plus {nr} chars to the left | |
| 4259 e end of the matched pattern | |
| 4260 e+{nr} end of the matched pattern plus {nr} chars to the right | |
| 4261 e-{nr} end of the matched pattern plus {nr} chars to the left | |
| 4229 | 4262 {nr} (for "lc" only): start matching {nr} chars right of the start |
| 7 | 4263 |
| 4264 Examples: "ms=s+1", "hs=e-2", "lc=3". | |
| 4265 | |
| 4266 Although all offsets are accepted after any pattern, they are not always | |
| 4267 meaningful. This table shows which offsets are actually used: | |
| 4268 | |
| 4269 ms me hs he rs re lc ~ | |
| 4270 match item yes yes yes yes - - yes | |
| 4271 region item start yes - yes - yes - yes | |
| 4272 region item skip - yes - - - - yes | |
| 4273 region item end - yes - yes - yes yes | |
| 4274 | |
| 4275 Offsets can be concatenated, with a ',' in between. Example: > | |
| 4276 :syn match String /"[^"]*"/hs=s+1,he=e-1 | |
| 4277 < | |
| 4278 some "string" text | |
| 4279 ^^^^^^ highlighted | |
| 4280 | |
| 4281 Notes: | |
| 4282 - There must be no white space between the pattern and the character | |
| 4283 offset(s). | |
| 4284 - The highlighted area will never be outside of the matched text. | |
| 4285 - A negative offset for an end pattern may not always work, because the end | |
| 4286 pattern may be detected when the highlighting should already have stopped. | |

4289 Vim 7.2 release. |
| 7 | 4290 - The start of a match cannot be in a line other than where the pattern |
| 4291 matched. This doesn't work: "a\nb"ms=e. You can make the highlighting | |
| 4292 start in another line, this does work: "a\nb"hs=e. | |
| 4293 | |
| 4294 Example (match a comment but don't highlight the /* and */): > | |
| 4295 :syntax region Comment start="/\*"hs=e+1 end="\*/"he=s-1 | |
| 4296 < | |
| 4297 /* this is a comment */ | |
| 4298 ^^^^^^^^^^^^^^^^^^^ highlighted | |

| 4301 :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 | |
| 4302 < | |

| 4304 mmmmmmmmmmm match | |

| 7 | 4306 |
| 4307 Leading context *:syn-lc* *:syn-leading* *:syn-context* | |
| 4308 | |
| 4309 Note: This is an obsolete feature, only included for backwards compatibility | |
| 4310 with previous Vim versions. It's now recommended to use the |/\@<=| construct | |
| 4311 in the pattern. | |
| 4312 | |
| 4313 The "lc" offset specifies leading context -- a part of the pattern that must | |
| 4314 be present, but is not considered part of the match. An offset of "lc=n" will | |
| 4315 cause Vim to step back n columns before attempting the pattern match, allowing | |
| 4316 characters which have already been matched in previous patterns to also be | |
| 4317 used as leading context for this match. This can be used, for instance, to | |
| 4318 specify that an "escaping" character must not precede the match: > | |
| 4319 | |
| 4320 :syn match ZNoBackslash "[^\\]z"ms=s+1 | |
| 4321 :syn match WNoBackslash "[^\\]w"lc=1 | |
| 4322 :syn match Underline "_\+" | |
| 4323 < | |
| 4324 ___zzzz ___wwww | |
| 4325 ^^^ ^^^ matches Underline | |
| 4326 ^ ^ matches ZNoBackslash | |
| 4327 ^^^^ matches WNoBackslash | |
| 4328 | |
| 4329 The "ms" offset is automatically set to the same value as the "lc" offset, | |
| 4330 unless you set "ms" explicitly. | |
| 4331 | |
| 4332 | |
| 4333 Multi-line patterns *:syn-multi-line* | |
| 4334 | |
| 4335 The patterns can include "\n" to match an end-of-line. Mostly this works as | |
| 4336 expected, but there are a few exceptions. | |
| 4337 | |
| 4338 When using a start pattern with an offset, the start of the match is not | |
| 4339 allowed to start in a following line. The highlighting can start in a | |

4341 the match doesn't move to another line. |
| 7 | 4342 |
| 4343 The skip pattern can include the "\n", but the search for an end pattern will | |
| 4344 continue in the first character of the next line, also when that character is | |
| 4345 matched by the skip pattern. This is because redrawing may start in any line | |
| 4346 halfway a region and there is no check if the skip pattern started in a | |
| 4347 previous line. For example, if the skip pattern is "a\nb" and an end pattern | |
| 4348 is "b", the end pattern does match in the second line of this: > | |
| 4349 x x a | |
| 4350 b x x | |
| 4351 Generally this means that the skip pattern should not match any characters | |
| 4352 after the "\n". | |
| 4353 | |
| 4354 | |
| 4355 External matches *:syn-ext-match* | |
| 4356 | |
| 4357 These extra regular expression items are available in region patterns: | |
| 4358 | |
| 4780 | 4359 */\z(* */\z(\)* *E50* *E52* *E879* |
| 4073 | 4360 \z(\) Marks the sub-expression as "external", meaning that it can be |
| 4361 accessed from another pattern match. Currently only usable in | |
| 4362 defining a syntax region start pattern. | |
| 7 | 4363 |
| 4364 */\z1* */\z2* */\z3* */\z4* */\z5* | |
| 4365 \z1 ... \z9 */\z6* */\z7* */\z8* */\z9* *E66* *E67* | |
| 4366 Matches the same string that was matched by the corresponding | |
| 4367 sub-expression in a previous start pattern match. | |
| 4368 | |
| 4369 Sometimes the start and end patterns of a region need to share a common | |
| 4370 sub-expression. A common example is the "here" document in Perl and many Unix | |
| 4371 shells. This effect can be achieved with the "\z" special regular expression | |
| 4372 items, which marks a sub-expression as "external", in the sense that it can be | |
| 4373 referenced from outside the pattern in which it is defined. The here-document | |
| 4374 example, for instance, can be done like this: > | |
| 4375 :syn region hereDoc start="<<\z(\I\i*\)" end="^\z1$" | |
| 4376 | |
| 4377 As can be seen here, the \z actually does double duty. In the start pattern, | |
| 4378 it marks the "\(\I\i*\)" sub-expression as external; in the end pattern, it | |

4379 changes the \z1 back-reference into an external reference referring to the |
| 7 | 4380 first external sub-expression in the start pattern. External references can |
| 4381 also be used in skip patterns: > | |
| 4382 :syn region foo start="start \(\I\i*\)" skip="not end \z1" end="end \z1" | |
| 4383 | |
| 4384 Note that normal and external sub-expressions are completely orthogonal and | |
| 4385 indexed separately; for instance, if the pattern "\z(..\)\(..\)" is applied | |
| 4386 to the string "aabb", then \1 will refer to "bb" and \z1 will refer to "aa". | |
| 4387 Note also that external sub-expressions cannot be accessed as back-references | |
| 4388 within the same pattern like normal sub-expressions. If you want to use one | |
| 4389 sub-expression as both a normal and an external sub-expression, you can nest | |
| 4390 the two, as in "\(\z(...\)\)". | |
| 4391 | |
| 4392 Note that only matches within a single line can be used. Multi-line matches | |
| 4393 cannot be referred to. | |
| 4394 | |
| 4395 ============================================================================== | |
| 15194 | 4396 9. Syntax clusters *:syn-cluster* *E400* |
| 7 | 4397 |
| 4398 :sy[ntax] cluster {cluster-name} [contains={group-name}..] | |
| 4399 [add={group-name}..] | |
| 4400 [remove={group-name}..] | |
| 4401 | |
| 4402 This command allows you to cluster a list of syntax groups together under a | |
| 4403 single name. | |
| 4404 | |
| 4405 contains={group-name}.. | |
| 4406 The cluster is set to the specified list of groups. | |
| 4407 add={group-name}.. | |
| 4408 The specified groups are added to the cluster. | |
| 4409 remove={group-name}.. | |
| 4410 The specified groups are removed from the cluster. | |
| 4411 | |
| 1624 | 4412 A cluster so defined may be referred to in a contains=.., containedin=.., |
| 4413 nextgroup=.., add=.. or remove=.. list with a "@" prefix. You can also use | |
| 4414 this notation to implicitly declare a cluster before specifying its contents. | |
| 7 | 4415 |
| 4416 Example: > | |
| 4417 :syntax match Thing "# [^#]\+ #" contains=@ThingMembers | |
| 4418 :syntax cluster ThingMembers contains=ThingMember1,ThingMember2 | |
| 4419 | |
| 4420 As the previous example suggests, modifications to a cluster are effectively | |
| 4421 retroactive; the membership of the cluster is checked at the last minute, so | |
| 4422 to speak: > | |
| 4423 :syntax keyword A aaa | |
| 4424 :syntax keyword B bbb | |
| 4425 :syntax cluster AandB contains=A | |
| 4426 :syntax match Stuff "( aaa bbb )" contains=@AandB | |
| 4427 :syntax cluster AandB add=B " now both keywords are matched in Stuff | |
| 4428 | |
| 4429 This also has implications for nested clusters: > | |
| 4430 :syntax keyword A aaa | |
| 4431 :syntax keyword B bbb | |
| 4432 :syntax cluster SmallGroup contains=B | |
| 4433 :syntax cluster BigGroup contains=A,@SmallGroup | |
| 4434 :syntax match Stuff "( aaa bbb )" contains=@BigGroup | |
| 4435 :syntax cluster BigGroup remove=B " no effect, since B isn't in BigGroup | |
| 4436 :syntax cluster SmallGroup remove=B " now bbb isn't matched within Stuff | |
| 2751 | 4437 < |
| 4438 *E848* | |
| 4439 The maximum number of clusters is 9767. | |
| 7 | 4440 |
| 4441 ============================================================================== | |
| 15194 | 4442 10. Including syntax files *:syn-include* *E397* |
| 7 | 4443 |
| 4444 It is often useful for one language's syntax file to include a syntax file for | |
| 4445 a related language. Depending on the exact relationship, this can be done in | |
| 4446 two different ways: | |
| 4447 | |
| 4448 - If top-level syntax items in the included syntax file are to be | |
| 4449 allowed at the top level in the including syntax, you can simply use | |
| 4450 the |:runtime| command: > | |
| 4451 | |
| 4452 " In cpp.vim: | |
| 4453 :runtime! syntax/c.vim | |
| 4454 :unlet b:current_syntax | |
| 4455 | |
| 4456 < - If top-level syntax items in the included syntax file are to be | |
| 4457 contained within a region in the including syntax, you can use the | |
| 4458 ":syntax include" command: | |
| 4459 | |
| 4460 :sy[ntax] include [@{grouplist-name}] {file-name} | |
| 4461 | |
| 4462 All syntax items declared in the included file will have the | |
| 4463 "contained" flag added. In addition, if a group list is specified, | |
| 4464 all top-level syntax items in the included file will be added to | |
| 4465 that list. > | |
| 4466 | |
| 4467 " In perl.vim: | |
| 4468 :syntax include @Pod <sfile>:p:h/pod.vim | |
| 4469 :syntax region perlPOD start="^=head" end="^=cut" contains=@Pod | |
| 4470 < | |
| 4471 When {file-name} is an absolute path (starts with "/", "c:", "$VAR" | |
| 4472 or "<sfile>") that file is sourced. When it is a relative path | |
| 4473 (e.g., "syntax/pod.vim") the file is searched for in 'runtimepath'. | |
| 4474 All matching files are loaded. Using a relative path is | |
| 4475 recommended, because it allows a user to replace the included file | |
| 4476 with his own version, without replacing the file that does the ":syn | |
| 4477 include". | |
| 4478 | |
| 2751 | 4479 *E847* |
| 4480 The maximum number of includes is 999. | |
| 4481 | |
| 7 | 4482 ============================================================================== |
| 15194 | 4483 11. Synchronizing *:syn-sync* *E403* *E404* |
| 7 | 4484 |
| 4485 Vim wants to be able to start redrawing in any position in the document. To | |
| 4486 make this possible it needs to know the syntax state at the position where | |
| 4487 redrawing starts. | |
| 4488 | |
| 4489 :sy[ntax] sync [ccomment [group-name] | minlines={N} | ...] | |
| 4490 | |
| 4491 There are four ways to synchronize: | |
| 4492 1. Always parse from the start of the file. | |
| 4493 |:syn-sync-first| | |
| 4494 2. Based on C-style comments. Vim understands how C-comments work and can | |
| 4495 figure out if the current line starts inside or outside a comment. | |
| 4496 |:syn-sync-second| | |
| 4497 3. Jumping back a certain number of lines and start parsing there. | |
| 4498 |:syn-sync-third| | |
| 4499 4. Searching backwards in the text for a pattern to sync on. | |
| 4500 |:syn-sync-fourth| | |
| 4501 | |
| 4502 *:syn-sync-maxlines* *:syn-sync-minlines* | |
| 4503 For the last three methods, the line range where the parsing can start is | |
| 4504 limited by "minlines" and "maxlines". | |
| 4505 | |
| 4506 If the "minlines={N}" argument is given, the parsing always starts at least | |
| 4507 that many lines backwards. This can be used if the parsing may take a few | |
| 4508 lines before it's correct, or when it's not possible to use syncing. | |
| 4509 | |
| 4510 If the "maxlines={N}" argument is given, the number of lines that are searched | |
| 4511 for a comment or syncing pattern is restricted to N lines backwards (after | |
| 4512 adding "minlines"). This is useful if you have few things to sync on and a | |
| 4513 slow machine. Example: > | |
| 6647 | 4514 :syntax sync maxlines=500 ccomment |
| 7 | 4515 < |
| 4516 *:syn-sync-linebreaks* | |
| 4517 When using a pattern that matches multiple lines, a change in one line may | |
| 4518 cause a pattern to no longer match in a previous line. This means has to | |
| 4519 start above where the change was made. How many lines can be specified with | |
| 4520 the "linebreaks" argument. For example, when a pattern may include one line | |
| 4521 break use this: > | |
| 4522 :syntax sync linebreaks=1 | |
| 4523 The result is that redrawing always starts at least one line before where a | |
| 4524 change was made. The default value for "linebreaks" is zero. Usually the | |
| 4525 value for "minlines" is bigger than "linebreaks". | |
| 4526 | |
| 4527 | |
| 4528 First syncing method: *:syn-sync-first* | |
| 4529 > | |
| 4530 :syntax sync fromstart | |
| 4531 | |
| 4532 The file will be parsed from the start. This makes syntax highlighting | |
| 4533 accurate, but can be slow for long files. Vim caches previously parsed text, | |
| 4534 so that it's only slow when parsing the text for the first time. However, | |
| 3224 | 4535 when making changes some part of the text needs to be parsed again (worst |
| 7 | 4536 case: to the end of the file). |
| 4537 | |
| 4538 Using "fromstart" is equivalent to using "minlines" with a very large number. | |
| 4539 | |
| 4540 | |
| 4541 Second syncing method: *:syn-sync-second* *:syn-sync-ccomment* | |
| 4542 | |
| 4543 For the second method, only the "ccomment" argument needs to be given. | |
| 4544 Example: > | |
| 4545 :syntax sync ccomment | |
| 4546 | |
| 4547 When Vim finds that the line where displaying starts is inside a C-style | |
| 4548 comment, the last region syntax item with the group-name "Comment" will be | |
| 4549 used. This requires that there is a region with the group-name "Comment"! | |
| 4550 An alternate group name can be specified, for example: > | |
| 4551 :syntax sync ccomment javaComment | |
| 4552 This means that the last item specified with "syn region javaComment" will be | |
| 4553 used for the detected C comment region. This only works properly if that | |
| 4554 region does have a start pattern "\/*" and an end pattern "*\/". | |
| 4555 | |
| 4556 The "maxlines" argument can be used to restrict the search to a number of | |
| 4557 lines. The "minlines" argument can be used to at least start a number of | |
| 4558 lines back (e.g., for when there is some construct that only takes a few | |
| 4559 lines, but it hard to sync on). | |
| 4560 | |
| 4561 Note: Syncing on a C comment doesn't work properly when strings are used | |
| 4562 that cross a line and contain a "*/". Since letting strings cross a line | |
| 4563 is a bad programming habit (many compilers give a warning message), and the | |
| 4564 chance of a "*/" appearing inside a comment is very small, this restriction | |
| 4565 is hardly ever noticed. | |
| 4566 | |
| 4567 | |
| 4568 Third syncing method: *:syn-sync-third* | |
| 4569 | |
| 4570 For the third method, only the "minlines={N}" argument needs to be given. | |
| 4571 Vim will subtract {N} from the line number and start parsing there. This | |
| 4572 means {N} extra lines need to be parsed, which makes this method a bit slower. | |
| 4573 Example: > | |
| 4574 :syntax sync minlines=50 | |
| 4575 | |
| 4576 "lines" is equivalent to "minlines" (used by older versions). | |
| 4577 | |
| 4578 | |
| 4579 Fourth syncing method: *:syn-sync-fourth* | |
| 4580 | |
| 4581 The idea is to synchronize on the end of a few specific regions, called a | |
| 4582 sync pattern. Only regions can cross lines, so when we find the end of some | |
| 4583 region, we might be able to know in which syntax item we are. The search | |
| 4584 starts in the line just above the one where redrawing starts. From there | |
| 4585 the search continues backwards in the file. | |
| 4586 | |
| 4587 This works just like the non-syncing syntax items. You can use contained | |
| 4588 matches, nextgroup, etc. But there are a few differences: | |
| 4589 - Keywords cannot be used. | |
| 4590 - The syntax items with the "sync" keyword form a completely separated group | |
| 4591 of syntax items. You can't mix syncing groups and non-syncing groups. | |
| 4592 - The matching works backwards in the buffer (line by line), instead of | |
| 4593 forwards. | |
| 4594 - A line continuation pattern can be given. It is used to decide which group | |
| 4595 of lines need to be searched like they were one line. This means that the | |
| 4596 search for a match with the specified items starts in the first of the | |
| 4597 consecutive that contain the continuation pattern. | |
| 4598 - When using "nextgroup" or "contains", this only works within one line (or | |
| 4599 group of continued lines). | |
| 4600 - When using a region, it must start and end in the same line (or group of | |
| 4601 continued lines). Otherwise the end is assumed to be at the end of the | |
| 4602 line (or group of continued lines). | |
| 4603 - When a match with a sync pattern is found, the rest of the line (or group of | |
| 4604 continued lines) is searched for another match. The last match is used. | |
| 4605 This is used when a line can contain both the start end the end of a region | |
| 4606 (e.g., in a C-comment like /* this */, the last "*/" is used). | |
| 4607 | |
| 4608 There are two ways how a match with a sync pattern can be used: | |
| 4609 1. Parsing for highlighting starts where redrawing starts (and where the | |
| 4610 search for the sync pattern started). The syntax group that is expected | |
| 4611 to be valid there must be specified. This works well when the regions | |
| 4612 that cross lines cannot contain other regions. | |
| 4613 2. Parsing for highlighting continues just after the match. The syntax group | |
| 4614 that is expected to be present just after the match must be specified. | |
| 4615 This can be used when the previous method doesn't work well. It's much | |
| 4616 slower, because more text needs to be parsed. | |
| 4617 Both types of sync patterns can be used at the same time. | |
| 4618 | |
| 4619 Besides the sync patterns, other matches and regions can be specified, to | |
| 4620 avoid finding unwanted matches. | |
| 4621 | |
| 4622 [The reason that the sync patterns are given separately, is that mostly the | |
| 4623 search for the sync point can be much simpler than figuring out the | |
| 4624 highlighting. The reduced number of patterns means it will go (much) | |
| 4625 faster.] | |
| 4626 | |
| 4627 *syn-sync-grouphere* *E393* *E394* | |
| 4628 :syntax sync match {sync-group-name} grouphere {group-name} "pattern" .. | |
| 4629 | |
| 4630 Define a match that is used for syncing. {group-name} is the | |
| 4631 name of a syntax group that follows just after the match. Parsing | |
| 4632 of the text for highlighting starts just after the match. A region | |
| 4633 must exist for this {group-name}. The first one defined will be used. | |
| 4634 "NONE" can be used for when there is no syntax group after the match. | |
| 4635 | |
| 4636 *syn-sync-groupthere* | |
| 4637 :syntax sync match {sync-group-name} groupthere {group-name} "pattern" .. | |
| 4638 | |
| 4639 Like "grouphere", but {group-name} is the name of a syntax group that | |
| 4640 is to be used at the start of the line where searching for the sync | |
| 4641 point started. The text between the match and the start of the sync | |
| 4642 pattern searching is assumed not to change the syntax highlighting. | |
| 4643 For example, in C you could search backwards for "/*" and "*/". If | |
| 4644 "/*" is found first, you know that you are inside a comment, so the | |
| 4645 "groupthere" is "cComment". If "*/" is found first, you know that you | |
| 4646 are not in a comment, so the "groupthere" is "NONE". (in practice | |
| 4647 it's a bit more complicated, because the "/*" and "*/" could appear | |
| 4648 inside a string. That's left as an exercise to the reader...). | |
| 4649 | |
| 4650 :syntax sync match .. | |
| 4651 :syntax sync region .. | |
| 4652 | |
| 4653 Without a "groupthere" argument. Define a region or match that is | |
| 4654 skipped while searching for a sync point. | |
| 4655 | |
| 856 | 4656 *syn-sync-linecont* |
| 7 | 4657 :syntax sync linecont {pattern} |
| 4658 | |
| 4659 When {pattern} matches in a line, it is considered to continue in | |
| 4660 the next line. This means that the search for a sync point will | |
| 4661 consider the lines to be concatenated. | |
| 4662 | |
| 4663 If the "maxlines={N}" argument is given too, the number of lines that are | |
| 4664 searched for a match is restricted to N. This is useful if you have very | |
| 4665 few things to sync on and a slow machine. Example: > | |
| 4666 :syntax sync maxlines=100 | |
| 4667 | |
| 4668 You can clear all sync settings with: > | |
| 4669 :syntax sync clear | |
| 4670 | |
| 4671 You can clear specific sync patterns with: > | |
| 4672 :syntax sync clear {sync-group-name} .. | |
| 4673 | |
| 4674 ============================================================================== | |
| 15194 | 4675 12. Listing syntax items *:syntax* *:sy* *:syn* *:syn-list* |
| 7 | 4676 |
| 534 | 4677 This command lists all the syntax items: > |
| 7 | 4678 |
| 4679 :sy[ntax] [list] | |
| 4680 | |
| 4681 To show the syntax items for one syntax group: > | |
| 4682 | |
| 4683 :sy[ntax] list {group-name} | |
| 4684 | |
| 2581 | 4685 To list the syntax groups in one cluster: *E392* > |
| 7 | 4686 |
| 4687 :sy[ntax] list @{cluster-name} | |
| 4688 | |
| 4689 See above for other arguments for the ":syntax" command. | |
| 4690 | |
| 4691 Note that the ":syntax" command can be abbreviated to ":sy", although ":syn" | |
| 4692 is mostly used, because it looks better. | |
| 4693 | |
| 4694 ============================================================================== | |
| 15194 | 4695 13. Highlight command *:highlight* *:hi* *E28* *E411* *E415* |
| 7 | 4696 |
| 4697 There are three types of highlight groups: | |
| 4698 - The ones used for specific languages. For these the name starts with the | |
| 4699 name of the language. Many of these don't have any attributes, but are | |
| 4700 linked to a group of the second type. | |
| 4701 - The ones used for all syntax languages. | |
| 4702 - The ones used for the 'highlight' option. | |
| 4703 *hitest.vim* | |
| 4704 You can see all the groups currently active with this command: > | |
| 4705 :so $VIMRUNTIME/syntax/hitest.vim | |
| 4706 This will open a new window containing all highlight group names, displayed | |
| 4707 in their own color. | |
| 4708 | |
| 4709 *:colo* *:colorscheme* *E185* | |
| 2152 | 4710 :colo[rscheme] Output the name of the currently active color scheme. |
| 4711 This is basically the same as > | |
| 4712 :echo g:colors_name | |
| 4713 < In case g:colors_name has not been defined :colo will | |
| 4714 output "default". When compiled without the |+eval| | |
| 4715 feature it will output "unknown". | |
| 4716 | |
| 7 | 4717 :colo[rscheme] {name} Load color scheme {name}. This searches 'runtimepath' |

| 4740 attributes set. | |
| 4741 | |
| 4742 :hi[ghlight] {group-name} | |
| 4743 List one highlight group. | |
| 4744 | |
| 4745 :hi[ghlight] clear Reset all highlighting to the defaults. Removes all | |
| 4746 highlighting for groups added by the user! | |
| 4747 Uses the current value of 'background' to decide which | |
| 4748 default colors to use. | |
| 4749 | |
| 4750 :hi[ghlight] clear {group-name} | |
| 4751 :hi[ghlight] {group-name} NONE | |
| 4752 Disable the highlighting for one highlight group. It | |
| 4753 is _not_ set back to the default colors. | |
| 4754 | |
| 4755 :hi[ghlight] [default] {group-name} {key}={arg} .. | |
| 4756 Add a highlight group, or change the highlighting for | |
| 4757 an existing group. | |
| 4758 See |highlight-args| for the {key}={arg} arguments. | |
| 4759 See |:highlight-default| for the optional [default] | |
| 4760 argument. | |
| 4761 | |
| 4762 Normally a highlight group is added once when starting up. This sets the | |
| 4763 default values for the highlighting. After that, you can use additional | |
| 4764 highlight commands to change the arguments that you want to set to non-default | |
| 4765 values. The value "NONE" can be used to switch the value off or go back to | |
| 4766 the default value. | |
| 4767 | |
| 4768 A simple way to change colors is with the |:colorscheme| command. This loads | |
| 4769 a file with ":highlight" commands such as this: > | |
| 4770 | |
| 4771 :hi Comment gui=bold | |
| 4772 | |
| 4773 Note that all settings that are not included remain the same, only the | |
| 4774 specified field is used, and settings are merged with previous ones. So, the | |
| 4775 result is like this single command has been used: > | |
| 4776 :hi Comment term=bold ctermfg=Cyan guifg=#80a0ff gui=bold | |
| 4777 < | |
| 856 | 4778 *:highlight-verbose* |
| 448 | 4779 When listing a highlight group and 'verbose' is non-zero, the listing will |
| 4780 also tell where it was last set. Example: > | |
| 4781 :verbose hi Comment | |
| 4782 < Comment xxx term=bold ctermfg=4 guifg=Blue ~ | |
| 856 | 4783 Last set from /home/mool/vim/vim7/runtime/syntax/syncolor.vim ~ |
| 448 | 4784 |
| 484 | 4785 When ":hi clear" is used then the script where this command is used will be |
| 4786 mentioned for the default values. See |:verbose-cmd| for more information. | |
| 448 | 4787 |
| 7 | 4788 *highlight-args* *E416* *E417* *E423* |
| 4789 There are three types of terminals for highlighting: | |
| 4790 term a normal terminal (vt100, xterm) | |
| 4791 cterm a color terminal (MS-DOS console, color-xterm, these have the "Co" | |
| 4792 termcap entry) | |
| 4793 gui the GUI | |
| 4794 | |
| 4795 For each type the highlighting can be given. This makes it possible to use | |
| 4796 the same syntax file on all terminals, and use the optimal highlighting. | |

4821 is only available in the GUI. The color is set with |highlight-guisp|. |
| 7 | 4822 |
| 4823 start={term-list} *highlight-start* *E422* | |
| 4824 stop={term-list} *term-list* *highlight-stop* | |
| 4825 These lists of terminal codes can be used to get | |
| 4826 non-standard attributes on a terminal. | |
| 4827 | |
| 4828 The escape sequence specified with the "start" argument | |
| 4829 is written before the characters in the highlighted | |
| 4830 area. It can be anything that you want to send to the | |
| 4831 terminal to highlight this area. The escape sequence | |
| 4832 specified with the "stop" argument is written after the | |
| 4833 highlighted area. This should undo the "start" argument. | |
| 4834 Otherwise the screen will look messed up. | |
| 4835 | |
| 4836 The {term-list} can have two forms: | |
| 4837 | |
| 4838 1. A string with escape sequences. | |
| 4839 This is any string of characters, except that it can't start with | |
| 4840 "t_" and blanks are not allowed. The <> notation is recognized | |
| 4841 here, so you can use things like "<Esc>" and "<Space>". Example: | |
| 4842 start=<Esc>[27h;<Esc>[<Space>r; | |
| 4843 | |
| 4844 2. A list of terminal codes. | |
| 4845 Each terminal code has the form "t_xx", where "xx" is the name of | |
| 4846 the termcap entry. The codes have to be separated with commas. | |
| 4847 White space is not allowed. Example: | |
| 4848 start=t_C1,t_BL | |
| 4849 The terminal codes must exist for this to work. | |
| 4850 | |
| 4851 | |
| 4852 2. highlight arguments for color terminals | |
| 4853 | |
| 4854 cterm={attr-list} *highlight-cterm* | |
| 4855 See above for the description of {attr-list} |attr-list|. | |
| 4856 The "cterm" argument is likely to be different from "term", when | |
| 4857 colors are used. For example, in a normal terminal comments could | |
| 4858 be underlined, in a color terminal they can be made Blue. | |
| 16808 | 4859 Note: Some terminals (e.g., DOS console) can't mix these attributes |
| 4860 with coloring. To be portable, use only one of "cterm=" OR "ctermfg=" | |
| 4861 OR "ctermbg=". | |
| 7 | 4862 |
| 4863 ctermfg={color-nr} *highlight-ctermfg* *E421* | |
| 4864 ctermbg={color-nr} *highlight-ctermbg* | |
| 4865 The {color-nr} argument is a color number. Its range is zero to | |
| 4866 (not including) the number given by the termcap entry "Co". | |
| 4867 The actual color with this number depends on the type of terminal | |
| 4868 and its settings. Sometimes the color also depends on the settings of | |
| 4869 "cterm". For example, on some systems "cterm=bold ctermfg=3" gives | |
| 4870 another color, on others you just get color 3. | |
| 4871 | |
| 4872 For an xterm this depends on your resources, and is a bit | |
| 4873 unpredictable. See your xterm documentation for the defaults. The | |
| 4874 colors for a color-xterm can be changed from the .Xdefaults file. | |
| 4875 Unfortunately this means that it's not possible to get the same colors | |
| 4876 for each user. See |xterm-color| for info about color xterms. | |
| 4877 | |
| 4878 The MSDOS standard colors are fixed (in a console window), so these | |
| 4879 have been used for the names. But the meaning of color names in X11 | |
| 4880 are fixed, so these color settings have been used, to make the | |
| 4881 highlighting settings portable (complicated, isn't it?). The | |
| 4882 following names are recognized, with the color number used: | |
| 4883 | |
| 4884 *cterm-colors* | |
| 4885 NR-16 NR-8 COLOR NAME ~ | |
| 4886 0 0 Black | |
| 4887 1 4 DarkBlue | |
| 4888 2 2 DarkGreen | |
| 4889 3 6 DarkCyan | |
| 4890 4 1 DarkRed | |
| 4891 5 5 DarkMagenta | |
| 4892 6 3 Brown, DarkYellow | |
| 4893 7 7 LightGray, LightGrey, Gray, Grey | |
| 4894 8 0* DarkGray, DarkGrey | |
| 4895 9 4* Blue, LightBlue | |
| 4896 10 2* Green, LightGreen | |
| 4897 11 6* Cyan, LightCyan | |
| 4898 12 1* Red, LightRed | |
| 4899 13 5* Magenta, LightMagenta | |
| 4900 14 3* Yellow, LightYellow | |
| 4901 15 7* White | |
| 4902 | |
| 4903 The number under "NR-16" is used for 16-color terminals ('t_Co' | |
| 4904 greater than or equal to 16). The number under "NR-8" is used for | |
| 4905 8-color terminals ('t_Co' less than 16). The '*' indicates that the | |
| 4906 bold attribute is set for ctermfg. In many 8-color terminals (e.g., | |
| 4907 "linux"), this causes the bright colors to appear. This doesn't work | |
| 4908 for background colors! Without the '*' the bold attribute is removed. | |
| 4909 If you want to set the bold attribute in a different way, put a | |
| 4910 "cterm=" argument AFTER the "ctermfg=" or "ctermbg=" argument. Or use | |
| 4911 a number instead of a color name. | |
| 4912 | |
| 4913 The case of the color names is ignored. | |
| 4914 Note that for 16 color ansi style terminals (including xterms), the | |
| 237 | 4915 numbers in the NR-8 column is used. Here '*' means 'add 8' so that Blue |
| 7 | 4916 is 12, DarkGray is 8 etc. |
| 4917 | |
| 4918 Note that for some color terminals these names may result in the wrong | |
| 4919 colors! | |
| 4920 | |
| 6697 | 4921 You can also use "NONE" to remove the color. |
| 4922 | |
| 7 | 4923 *:hi-normal-cterm* |
| 4924 When setting the "ctermfg" or "ctermbg" colors for the Normal group, | |
| 4925 these will become the colors used for the non-highlighted text. | |
| 4926 Example: > | |
| 4927 :highlight Normal ctermfg=grey ctermbg=darkblue | |
| 4928 < When setting the "ctermbg" color for the Normal group, the | |
| 11473 | 4929 'background' option will be adjusted automatically, under the |
| 4930 condition that the color is recognized and 'background' was not set | |
| 4931 explicitly. This causes the highlight groups that depend on | |
| 4932 'background' to change! This means you should set the colors for | |
| 4933 Normal first, before setting other colors. | |
| 16208 | 4934 When a color scheme is being used, changing 'background' causes it to |
| 7 | 4935 be reloaded, which may reset all colors (including Normal). First |

4936 delete the "g:colors_name" variable when you don't want this. |
| 7 | 4937 |
| 4938 When you have set "ctermfg" or "ctermbg" for the Normal group, Vim | |
| 4939 needs to reset the color when exiting. This is done with the "op" | |
| 4940 termcap entry |t_op|. If this doesn't work correctly, try setting the | |
| 4941 't_op' option in your .vimrc. | |
| 4942 *E419* *E420* | |
| 4943 When Vim knows the normal foreground and background colors, "fg" and | |
| 4944 "bg" can be used as color names. This only works after setting the | |
| 4945 colors for the Normal group and for the MS-DOS console. Example, for | |
| 4946 reverse video: > | |
| 4947 :highlight Visual ctermfg=bg ctermbg=fg | |
| 4948 < Note that the colors are used that are valid at the moment this | |
| 4949 command are given. If the Normal group colors are changed later, the | |
| 4950 "fg" and "bg" colors will not be adjusted. | |
| 4951 | |
| 4952 | |
| 4953 3. highlight arguments for the GUI | |
| 4954 | |
| 4955 gui={attr-list} *highlight-gui* | |
| 4956 These give the attributes to use in the GUI mode. | |
| 4957 See |attr-list| for a description. | |
| 4958 Note that "bold" can be used here and by using a bold font. They | |
| 4959 have the same effect. | |
| 4960 Note that the attributes are ignored for the "Normal" group. | |
| 4961 | |
| 4962 font={font-name} *highlight-font* | |
| 4963 font-name is the name of a font, as it is used on the system Vim | |
| 4964 runs on. For X11 this is a complicated name, for example: > | |
| 4965 font=-misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1 | |
| 4966 < | |
| 4967 The font-name "NONE" can be used to revert to the default font. | |
| 4968 When setting the font for the "Normal" group, this becomes the default | |
| 4969 font (until the 'guifont' option is changed; the last one set is | |
| 4970 used). | |
| 4971 The following only works with Motif and Athena, not with other GUIs: | |
| 4972 When setting the font for the "Menu" group, the menus will be changed. | |
| 4973 When setting the font for the "Tooltip" group, the tooltips will be | |
| 4974 changed. | |
| 4975 All fonts used, except for Menu and Tooltip, should be of the same | |
| 4976 character size as the default font! Otherwise redrawing problems will | |
| 4977 occur. | |

| 1624 | 5162 For the GUI you can use the following groups to set the colors for the menu, |

| 15194 | 5192 14. Linking groups *:hi-link* *:highlight-link* *E412* *E413* |
| 7 | 5193 |
| 5194 When you want to use the same highlighting for several syntax groups, you | |
| 5195 can do this more easily by linking the groups into one common highlight | |
| 5196 group, and give the color attributes only for that group. | |
| 5197 | |
| 5198 To set a link: | |
| 5199 | |
| 5200 :hi[ghlight][!] [default] link {from-group} {to-group} | |
| 5201 | |
| 5202 To remove a link: | |
| 5203 | |
| 5204 :hi[ghlight][!] [default] link {from-group} NONE | |
| 5205 | |
| 5206 Notes: *E414* | |
| 5207 - If the {from-group} and/or {to-group} doesn't exist, it is created. You | |
| 5208 don't get an error message for a non-existing group. | |
| 5209 - As soon as you use a ":highlight" command for a linked group, the link is | |
| 5210 removed. | |
| 5211 - If there are already highlight settings for the {from-group}, the link is | |
| 5212 not made, unless the '!' is given. For a ":highlight link" command in a | |
| 5213 sourced file, you don't get an error message. This can be used to skip | |
| 5214 links for groups that already have settings. | |
| 5215 | |
| 5216 *:hi-default* *:highlight-default* | |
| 5217 The [default] argument is used for setting the default highlighting for a | |
| 5218 group. If highlighting has already been specified for the group the command | |
| 5219 will be ignored. Also when there is an existing link. | |
| 5220 | |
| 5221 Using [default] is especially useful to overrule the highlighting of a | |
| 5222 specific syntax file. For example, the C syntax file contains: > | |
| 5223 :highlight default link cComment Comment | |
| 5224 If you like Question highlighting for C comments, put this in your vimrc file: > | |
| 5225 :highlight link cComment Question | |
| 5226 Without the "default" in the C syntax file, the highlighting would be | |
| 5227 overruled when the syntax file is loaded. | |
| 5228 | |
| 5229 ============================================================================== | |
| 15194 | 5230 15. Cleaning up *:syn-clear* *E391* |
| 7 | 5231 |
| 5232 If you want to clear the syntax stuff for the current buffer, you can use this | |
| 5233 command: > | |
| 5234 :syntax clear | |
| 5235 | |
| 5236 This command should be used when you want to switch off syntax highlighting, | |
| 5237 or when you want to switch to using another syntax. It's normally not needed | |
| 5238 in a syntax file itself, because syntax is cleared by the autocommands that | |
| 5239 load the syntax file. | |
| 5240 The command also deletes the "b:current_syntax" variable, since no syntax is | |
| 5241 loaded after this command. | |
| 5242 | |
| 16944 | 5243 To clean up specific syntax groups for the current buffer: > |
| 5244 :syntax clear {group-name} .. | |
| 5245 This removes all patterns and keywords for {group-name}. | |
| 5246 | |
| 5247 To clean up specific syntax group lists for the current buffer: > | |
| 5248 :syntax clear @{grouplist-name} .. | |
| 5249 This sets {grouplist-name}'s contents to an empty list. | |
| 5250 | |
| 5251 *:syntax-off* *:syn-off* | |
| 7 | 5252 If you want to disable syntax highlighting for all buffers, you need to remove |
| 5253 the autocommands that load the syntax files: > | |
| 5254 :syntax off | |
| 5255 | |
| 5256 What this command actually does, is executing the command > | |
| 5257 :source $VIMRUNTIME/syntax/nosyntax.vim | |
| 5258 See the "nosyntax.vim" file for details. Note that for this to work | |
| 5259 $VIMRUNTIME must be valid. See |$VIMRUNTIME|. | |
| 5260 | |
| 5261 *:syntax-reset* *:syn-reset* | |
| 5262 If you have changed the colors and messed them up, use this command to get the | |
| 5263 defaults back: > | |
| 5264 | |
| 5265 :syntax reset | |
| 5266 | |

5269 |
| 7 | 5270 This doesn't change the colors for the 'highlight' option. |
| 5271 | |
| 5272 Note that the syntax colors that you set in your vimrc file will also be reset | |
| 5273 back to their Vim default. | |
| 5274 Note that if you are using a color scheme, the colors defined by the color | |
| 5275 scheme for syntax highlighting will be lost. | |
| 5276 | |
| 5277 What this actually does is: > | |
| 5278 | |
| 5279 let g:syntax_cmd = "reset" | |
| 5280 runtime! syntax/syncolor.vim | |
| 5281 | |
| 5282 Note that this uses the 'runtimepath' option. | |
| 5283 | |
| 5284 *syncolor* | |
| 5285 If you want to use different colors for syntax highlighting, you can add a Vim | |
| 5286 script file to set these colors. Put this file in a directory in | |
| 5287 'runtimepath' which comes after $VIMRUNTIME, so that your settings overrule | |
| 5288 the default colors. This way these colors will be used after the ":syntax | |
| 5289 reset" command. | |
| 5290 | |
| 5291 For Unix you can use the file ~/.vim/after/syntax/syncolor.vim. Example: > | |
| 5292 | |
| 5293 if &background == "light" | |
| 5294 highlight comment ctermfg=darkgreen guifg=darkgreen | |
| 5295 else | |
| 5296 highlight comment ctermfg=green guifg=green | |
| 5297 endif | |
| 5298 | |
| 24 | 5299 *E679* |
| 5300 Do make sure this syncolor.vim script does not use a "syntax on", set the | |
| 5301 'background' option or uses a "colorscheme" command, because it results in an | |
| 5302 endless loop. | |
| 5303 | |
| 7 | 5304 Note that when a color scheme is used, there might be some confusion whether |
| 5305 your defined colors are to be used or the colors from the scheme. This | |
| 5306 depends on the color scheme file. See |:colorscheme|. | |
| 5307 | |
| 5308 *syntax_cmd* | |
| 5309 The "syntax_cmd" variable is set to one of these values when the | |
| 5310 syntax/syncolor.vim files are loaded: | |
| 5311 "on" ":syntax on" command. Highlight colors are overruled but | |
| 5312 links are kept | |
| 5313 "enable" ":syntax enable" command. Only define colors for groups that | |
| 5314 don't have highlighting yet. Use ":syntax default". | |
| 5315 "reset" ":syntax reset" command or loading a color scheme. Define all | |
| 5316 the colors. | |
| 5317 "skip" Don't define colors. Used to skip the default settings when a | |
| 5318 syncolor.vim file earlier in 'runtimepath' has already set | |
| 5319 them. | |
| 5320 | |
| 5321 ============================================================================== | |
| 15194 | 5322 16. Highlighting tags *tag-highlight* |
| 7 | 5323 |
| 5324 If you want to highlight all the tags in your file, you can use the following | |
| 5325 mappings. | |
| 5326 | |
| 5327 <F11> -- Generate tags.vim file, and highlight tags. | |
| 5328 <F12> -- Just highlight tags based on existing tags.vim file. | |
| 5329 > | |
| 5330 :map <F11> :sp tags<CR>:%s/^\([^ :]*:\)\=\([^ ]*\).*/syntax keyword Tag \2/<CR>:wq! tags.vim<CR>/^<CR><F12> | |
| 5331 :map <F12> :so tags.vim<CR> | |
| 5332 | |
| 5333 WARNING: The longer the tags file, the slower this will be, and the more | |
| 5334 memory Vim will consume. | |

| 5336 Only highlighting typedefs, unions and structs can be done too. For this you | |
| 5337 must use Exuberant ctags (found at http://ctags.sf.net). | |
| 5338 | |
| 5339 Put these lines in your Makefile: | |
| 5340 | |
| 5341 # Make a highlight file for types. Requires Exuberant ctags and awk | |
| 5342 types: types.vim | |
| 5343 types.vim: *.[ch] | |

| 5346 {printf("%s ", $$1)}END{print ""}' > $@ | |
| 5347 | |
| 5348 And put these lines in your .vimrc: > | |
| 5349 | |
| 5350 " load the types.vim highlighting file, if it exists | |
| 5351 autocmd BufRead,BufNewFile *.[ch] let fname = expand('<afile>:p:h') . '/types.vim' | |

| 15194 | 5387 18. Color xterms *xterm-color* *color-xterm* |
| 7 | 5388 |
| 5389 Most color xterms have only eight colors. If you don't get colors with the | |
| 5390 default setup, it should work with these lines in your .vimrc: > | |
| 5391 :if &term =~ "xterm" | |
| 5392 : if has("terminfo") | |
| 5393 : set t_Co=8 | |
| 5394 : set t_Sf=<Esc>[3%p1%dm | |
| 5395 : set t_Sb=<Esc>[4%p1%dm | |
| 5396 : else | |
| 5397 : set t_Co=8 | |
| 5398 : set t_Sf=<Esc>[3%dm | |
| 5399 : set t_Sb=<Esc>[4%dm | |
| 5400 : endif | |
| 5401 :endif | |
| 5402 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 5403 | |
| 5404 You might want to change the first "if" to match the name of your terminal, | |
| 5405 e.g. "dtterm" instead of "xterm". | |
| 5406 | |
| 5407 Note: Do these settings BEFORE doing ":syntax on". Otherwise the colors may | |
| 5408 be wrong. | |
| 5409 *xiterm* *rxvt* | |
| 5410 The above settings have been mentioned to work for xiterm and rxvt too. | |
| 5411 But for using 16 colors in an rxvt these should work with terminfo: > | |
| 5412 :set t_AB=<Esc>[%?%p1%{8}%<%t25;%p1%{40}%+%e5;%p1%{32}%+%;%dm | |
| 5413 :set t_AF=<Esc>[%?%p1%{8}%<%t22;%p1%{30}%+%e1;%p1%{22}%+%;%dm | |
| 5414 < | |
| 5415 *colortest.vim* | |
| 5416 To test your color setup, a file has been included in the Vim distribution. | |
| 671 | 5417 To use it, execute this command: > |
| 5418 :runtime syntax/colortest.vim | |
| 7 | 5419 |
| 237 | 5420 Some versions of xterm (and other terminals, like the Linux console) can |
| 7 | 5421 output lighter foreground colors, even though the number of colors is defined |
| 5422 at 8. Therefore Vim sets the "cterm=bold" attribute for light foreground | |
| 5423 colors, when 't_Co' is 8. | |
| 5424 | |
| 5425 *xfree-xterm* | |
| 5426 To get 16 colors or more, get the newest xterm version (which should be | |
| 237 | 5427 included with XFree86 3.3 and later). You can also find the latest version |
| 7 | 5428 at: > |
| 5429 http://invisible-island.net/xterm/xterm.html | |
| 5430 Here is a good way to configure it. This uses 88 colors and enables the | |
| 5431 termcap-query feature, which allows Vim to ask the xterm how many colors it | |
| 5432 supports. > | |
| 5433 ./configure --disable-bold-color --enable-88-color --enable-tcap-query | |
| 5434 If you only get 8 colors, check the xterm compilation settings. | |
| 5435 (Also see |UTF8-xterm| for using this xterm with UTF-8 character encoding). | |
| 5436 | |
| 5437 This xterm should work with these lines in your .vimrc (for 16 colors): > | |
| 5438 :if has("terminfo") | |
| 5439 : set t_Co=16 | |
| 5440 : set t_AB=<Esc>[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{92}%+%;%dm | |
| 5441 : set t_AF=<Esc>[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{82}%+%;%dm | |
| 5442 :else | |
| 5443 : set t_Co=16 | |
| 5444 : set t_Sf=<Esc>[3%dm | |
| 5445 : set t_Sb=<Esc>[4%dm | |
| 5446 :endif | |
| 5447 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 5448 | |
| 5449 Without |+terminfo|, Vim will recognize these settings, and automatically | |
| 5450 translate cterm colors of 8 and above to "<Esc>[9%dm" and "<Esc>[10%dm". | |
| 5451 Colors above 16 are also translated automatically. | |
| 5452 | |
| 5453 For 256 colors this has been reported to work: > | |
| 5454 | |
| 5455 :set t_AB=<Esc>[48;5;%dm | |
| 5456 :set t_AF=<Esc>[38;5;%dm | |
| 5457 | |
| 5458 Or just set the TERM environment variable to "xterm-color" or "xterm-16color" | |
| 5459 and try if that works. | |
| 5460 | |
| 5461 You probably want to use these X resources (in your ~/.Xdefaults file): | |
| 5462 XTerm*color0: #000000 | |
| 5463 XTerm*color1: #c00000 | |
| 5464 XTerm*color2: #008000 | |
| 5465 XTerm*color3: #808000 | |
| 5466 XTerm*color4: #0000c0 | |
| 5467 XTerm*color5: #c000c0 | |
| 5468 XTerm*color6: #008080 | |
| 5469 XTerm*color7: #c0c0c0 | |
| 5470 XTerm*color8: #808080 | |
| 5471 XTerm*color9: #ff6060 | |
| 5472 XTerm*color10: #00ff00 | |
| 5473 XTerm*color11: #ffff00 | |
| 5474 XTerm*color12: #8080ff | |
| 5475 XTerm*color13: #ff40ff | |
| 5476 XTerm*color14: #00ffff | |
| 5477 XTerm*color15: #ffffff | |
| 5478 Xterm*cursorColor: Black | |
| 5479 | |
| 5480 [Note: The cursorColor is required to work around a bug, which changes the | |
| 5481 cursor color to the color of the last drawn text. This has been fixed by a | |
| 1125 | 5482 newer version of xterm, but not everybody is using it yet.] |
| 7 | 5483 |
| 5484 To get these right away, reload the .Xdefaults file to the X Option database | |
| 5485 Manager (you only need to do this when you just changed the .Xdefaults file): > | |
| 5486 xrdb -merge ~/.Xdefaults | |
| 5487 < | |
| 5488 *xterm-blink* *xterm-blinking-cursor* | |
| 5489 To make the cursor blink in an xterm, see tools/blink.c. Or use Thomas | |
| 5490 Dickey's xterm above patchlevel 107 (see above for where to get it), with | |
| 5491 these resources: | |
| 5492 XTerm*cursorBlink: on | |
| 5493 XTerm*cursorOnTime: 400 | |
| 5494 XTerm*cursorOffTime: 250 | |
| 5495 XTerm*cursorColor: White | |
| 5496 | |
| 5497 *hpterm-color* | |
| 1125 | 5498 These settings work (more or less) for an hpterm, which only supports 8 |
| 7 | 5499 foreground colors: > |
| 5500 :if has("terminfo") | |
| 5501 : set t_Co=8 | |
| 5502 : set t_Sf=<Esc>[&v%p1%dS | |
| 5503 : set t_Sb=<Esc>[&v7S | |
| 5504 :else | |
| 5505 : set t_Co=8 | |
| 5506 : set t_Sf=<Esc>[&v%dS | |
| 5507 : set t_Sb=<Esc>[&v7S | |
| 5508 :endif | |
| 5509 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 5510 | |
| 5511 *Eterm* *enlightened-terminal* | |
| 5512 These settings have been reported to work for the Enlightened terminal | |
| 5513 emulator, or Eterm. They might work for all xterm-like terminals that use the | |
| 5514 bold attribute to get bright colors. Add an ":if" like above when needed. > | |
| 5515 :set t_Co=16 | |
| 5516 :set t_AF=^[[%?%p1%{8}%<%t3%p1%d%e%p1%{22}%+%d;1%;m | |
| 5517 :set t_AB=^[[%?%p1%{8}%<%t4%p1%d%e%p1%{32}%+%d;1%;m | |
| 5518 < | |
| 5519 *TTpro-telnet* | |
| 5520 These settings should work for TTpro telnet. Tera Term Pro is a freeware / | |
| 5521 open-source program for MS-Windows. > | |
| 5522 set t_Co=16 | |
| 5523 set t_AB=^[[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{32}%+5;%;%dm | |
| 5524 set t_AF=^[[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{22}%+1;%;%dm | |
| 5525 Also make sure TTpro's Setup / Window / Full Color is enabled, and make sure | |
| 5526 that Setup / Font / Enable Bold is NOT enabled. | |
