| 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. | |

| 41 {Vi does not have any of these commands} | |
| 42 | |
| 43 Syntax highlighting is not available when the |+syntax| feature has been | |
| 44 disabled at compile time. | |
| 45 | |
| 46 ============================================================================== | |
| 47 1. Quick start *:syn-qstart* | |
| 48 | |
| 49 *:syn-enable* *:syntax-enable* | |
| 50 This command switches on syntax highlighting: > | |
| 51 | |
| 52 :syntax enable | |
| 53 | |
| 54 What this command actually does is to execute the command > | |
| 55 :source $VIMRUNTIME/syntax/syntax.vim | |
| 56 | |
| 57 If the VIM environment variable is not set, Vim will try to find | |
| 58 the path in another way (see |$VIMRUNTIME|). Usually this works just | |
| 59 fine. If it doesn't, try setting the VIM environment variable to the | |
| 60 directory where the Vim stuff is located. For example, if your syntax files | |
| 61 are in the "/usr/vim/vim50/syntax" directory, set $VIMRUNTIME to | |
| 62 "/usr/vim/vim50". You must do this in the shell, before starting Vim. | |
| 63 | |
| 64 *:syn-on* *:syntax-on* | |
| 65 The ":syntax enable" command will keep your current color settings. This | |
| 66 allows using ":highlight" commands to set your preferred colors before or | |
| 67 after using this command. If you want Vim to overrule your settings with the | |
| 68 defaults, use: > | |
| 69 :syntax on | |
| 70 < | |
| 71 *:hi-normal* *:highlight-normal* | |
| 72 If you are running in the GUI, you can get white text on a black background | |
| 73 with: > | |
| 74 :highlight Normal guibg=Black guifg=White | |
| 75 For a color terminal see |:hi-normal-cterm|. | |
| 76 For setting up your own colors syntax highlighting see |syncolor|. | |
| 77 | |
| 78 NOTE: The syntax files on MS-DOS and Windows have lines that end in <CR><NL>. | |
| 79 The files for Unix end in <NL>. This means you should use the right type of | |
| 80 file for your system. Although on MS-DOS and Windows the right format is | |
| 81 automatically selected if the 'fileformats' option is not empty. | |
| 82 | |
| 83 NOTE: When using reverse video ("gvim -fg white -bg black"), the default value | |
| 84 of 'background' will not be set until the GUI window is opened, which is after | |
| 819 | 85 reading the |gvimrc|. This will cause the wrong default highlighting to be |
| 7 | 86 used. To set the default value of 'background' before switching on |
| 819 | 87 highlighting, include the ":gui" command in the |gvimrc|: > |
| 7 | 88 |
| 89 :gui " open window and set default for 'background' | |
| 90 :syntax on " start highlighting, use 'background' to set colors | |
| 91 | |
| 819 | 92 NOTE: Using ":gui" in the |gvimrc| means that "gvim -f" won't start in the |
| 7 | 93 foreground! Use ":gui -f" then. |
| 94 | |
| 2520 | 95 *g:syntax_on* |
| 96 You can toggle the syntax on/off with this command: > | |
| 97 :if exists("g:syntax_on") | syntax off | else | syntax enable | endif | |
| 7 | 98 |
| 99 To put this into a mapping, you can use: > | |
| 2520 | 100 :map <F7> :if exists("g:syntax_on") <Bar> |
| 7 | 101 \ syntax off <Bar> |
| 102 \ else <Bar> | |
| 103 \ syntax enable <Bar> | |
| 104 \ endif <CR> | |
| 105 [using the |<>| notation, type this literally] | |
| 106 | |
| 1624 | 107 Details: |
| 7 | 108 The ":syntax" commands are implemented by sourcing a file. To see exactly how |
| 109 this works, look in the file: | |
| 110 command file ~ | |
| 111 :syntax enable $VIMRUNTIME/syntax/syntax.vim | |
| 112 :syntax on $VIMRUNTIME/syntax/syntax.vim | |
| 113 :syntax manual $VIMRUNTIME/syntax/manual.vim | |
| 114 :syntax off $VIMRUNTIME/syntax/nosyntax.vim | |
| 115 Also see |syntax-loading|. | |

| 121 2. Syntax files *:syn-files* | |
| 122 | |
| 123 The syntax and highlighting commands for one language are normally stored in | |
| 124 a syntax file. The name convention is: "{name}.vim". Where {name} is the | |
| 125 name of the language, or an abbreviation (to fit the name in 8.3 characters, | |
| 126 a requirement in case the file is used on a DOS filesystem). | |
| 127 Examples: | |
| 128 c.vim perl.vim java.vim html.vim | |
| 129 cpp.vim sh.vim csh.vim | |
| 130 | |
| 131 The syntax file can contain any Ex commands, just like a vimrc file. But | |
| 132 the idea is that only commands for a specific language are included. When a | |
| 133 language is a superset of another language, it may include the other one, | |
| 134 for example, the cpp.vim file could include the c.vim file: > | |
| 135 :so $VIMRUNTIME/syntax/c.vim | |
| 136 | |
| 137 The .vim files are normally loaded with an autocommand. For example: > | |
| 138 :au Syntax c runtime! syntax/c.vim | |
| 139 :au Syntax cpp runtime! syntax/cpp.vim | |
| 140 These commands are normally in the file $VIMRUNTIME/syntax/synload.vim. | |
| 141 | |
| 142 | |
| 143 MAKING YOUR OWN SYNTAX FILES *mysyntaxfile* | |
| 144 | |
| 145 When you create your own syntax files, and you want to have Vim use these | |
| 146 automatically with ":syntax enable", do this: | |
| 147 | |
| 148 1. Create your user runtime directory. You would normally use the first item | |
| 149 of the 'runtimepath' option. Example for Unix: > | |
| 150 mkdir ~/.vim | |
| 151 | |
| 152 2. Create a directory in there called "syntax". For Unix: > | |
| 153 mkdir ~/.vim/syntax | |
| 154 | |
| 155 3. Write the Vim syntax file. Or download one from the internet. Then write | |
| 156 it in your syntax directory. For example, for the "mine" syntax: > | |
| 157 :w ~/.vim/syntax/mine.vim | |
| 158 | |
| 159 Now you can start using your syntax file manually: > | |
| 160 :set syntax=mine | |
| 161 You don't have to exit Vim to use this. | |
| 162 | |
| 163 If you also want Vim to detect the type of file, see |new-filetype|. | |
| 164 | |
| 165 If you are setting up a system with many users and you don't want each user | |
| 166 to add the same syntax file, you can use another directory from 'runtimepath'. | |
| 167 | |
| 168 | |
| 169 ADDING TO AN EXISTING SYNTAX FILE *mysyntaxfile-add* | |
| 170 | |
| 171 If you are mostly satisfied with an existing syntax file, but would like to | |
| 172 add a few items or change the highlighting, follow these steps: | |
| 173 | |
| 174 1. Create your user directory from 'runtimepath', see above. | |
| 175 | |
| 176 2. Create a directory in there called "after/syntax". For Unix: > | |
| 177 mkdir ~/.vim/after | |
| 178 mkdir ~/.vim/after/syntax | |
| 179 | |
| 180 3. Write a Vim script that contains the commands you want to use. For | |
| 181 example, to change the colors for the C syntax: > | |
| 182 highlight cComment ctermfg=Green guifg=Green | |
| 183 | |
| 184 4. Write that file in the "after/syntax" directory. Use the name of the | |
| 185 syntax, with ".vim" added. For our C syntax: > | |
| 186 :w ~/.vim/after/syntax/c.vim | |
| 187 | |
| 188 That's it. The next time you edit a C file the Comment color will be | |
| 189 different. You don't even have to restart Vim. | |
| 190 | |
| 169 | 191 If you have multiple files, you can use the filetype as the directory name. |
| 192 All the "*.vim" files in this directory will be used, for example: | |
| 193 ~/.vim/after/syntax/c/one.vim | |
| 194 ~/.vim/after/syntax/c/two.vim | |
| 195 | |
| 7 | 196 |
| 197 REPLACING AN EXISTING SYNTAX FILE *mysyntaxfile-replace* | |
| 198 | |
| 199 If you don't like a distributed syntax file, or you have downloaded a new | |
| 200 version, follow the same steps as for |mysyntaxfile| above. Just make sure | |
| 201 that you write the syntax file in a directory that is early in 'runtimepath'. | |
| 202 Vim will only load the first syntax file found. | |
| 203 | |

| 7 | 211 The name for a highlight or syntax group must consist of ASCII letters, digits |
| 212 and the underscore. As a regexp: "[a-zA-Z0-9_]*" | |
| 213 | |
| 214 To be able to allow each user to pick his favorite set of colors, there must | |
| 215 be preferred names for highlight groups that are common for many languages. | |
| 216 These are the suggested group names (if syntax highlighting works properly | |
| 217 you can see the actual color, except for "Ignore"): | |
| 218 | |
| 219 *Comment any comment | |
| 220 | |
| 221 *Constant any constant | |
| 222 String a string constant: "this is a string" | |
| 223 Character a character constant: 'c', '\n' | |
| 224 Number a number constant: 234, 0xff | |
| 225 Boolean a boolean constant: TRUE, false | |
| 226 Float a floating point constant: 2.3e10 | |
| 227 | |
| 228 *Identifier any variable name | |
| 229 Function function name (also: methods for classes) | |
| 230 | |
| 231 *Statement any statement | |
| 232 Conditional if, then, else, endif, switch, etc. | |
| 233 Repeat for, do, while, etc. | |
| 234 Label case, default, etc. | |
| 235 Operator "sizeof", "+", "*", etc. | |
| 236 Keyword any other keyword | |
| 237 Exception try, catch, throw | |
| 238 | |
| 239 *PreProc generic Preprocessor | |
| 240 Include preprocessor #include | |
| 241 Define preprocessor #define | |
| 242 Macro same as Define | |
| 243 PreCondit preprocessor #if, #else, #endif, etc. | |
| 244 | |
| 245 *Type int, long, char, etc. | |
| 246 StorageClass static, register, volatile, etc. | |
| 247 Structure struct, union, enum, etc. | |
| 248 Typedef A typedef | |
| 249 | |
| 250 *Special any special symbol | |
| 251 SpecialChar special character in a constant | |
| 252 Tag you can use CTRL-] on this | |
| 253 Delimiter character that needs attention | |
| 254 SpecialComment special things inside a comment | |

259 *Ignore left blank, hidden |hl-Ignore| |
| 7 | 260 |
| 261 *Error any erroneous construct | |
| 262 | |
| 263 *Todo anything that needs extra attention; mostly the | |
| 264 keywords TODO FIXME and XXX | |
| 265 | |
| 266 The names marked with * are the preferred groups; the others are minor groups. | |
| 267 For the preferred groups, the "syntax.vim" file contains default highlighting. | |
| 268 The minor groups are linked to the preferred groups, so they get the same | |
| 269 highlighting. You can override these defaults by using ":highlight" commands | |
| 270 after sourcing the "syntax.vim" file. | |
| 271 | |
| 272 Note that highlight group names are not case sensitive. "String" and "string" | |
| 273 can be used for the same group. | |
| 274 | |
| 275 The following names are reserved and cannot be used as a group name: | |
| 276 NONE ALL ALLBUT contains contained | |

| 283 3. Syntax loading procedure *syntax-loading* | |
| 284 | |
| 285 This explains the details that happen when the command ":syntax enable" is | |
| 286 issued. When Vim initializes itself, it finds out where the runtime files are | |
| 287 located. This is used here as the variable |$VIMRUNTIME|. | |
| 288 | |
| 289 ":syntax enable" and ":syntax on" do the following: | |
| 290 | |
| 291 Source $VIMRUNTIME/syntax/syntax.vim | |
| 292 | | |
| 293 +- Clear out any old syntax by sourcing $VIMRUNTIME/syntax/nosyntax.vim | |
| 294 | | |
| 295 +- Source first syntax/synload.vim in 'runtimepath' | |
| 296 | | | |
| 297 | +- Setup the colors for syntax highlighting. If a color scheme is | |
| 298 | | defined it is loaded again with ":colors {name}". Otherwise | |
| 299 | | ":runtime! syntax/syncolor.vim" is used. ":syntax on" overrules | |
| 300 | | existing colors, ":syntax enable" only sets groups that weren't | |
| 301 | | set yet. | |
| 302 | | | |
| 303 | +- Set up syntax autocmds to load the appropriate syntax file when | |
| 304 | | the 'syntax' option is set. *synload-1* | |
| 305 | | | |
| 306 | +- Source the user's optional file, from the |mysyntaxfile| variable. | |
| 307 | This is for backwards compatibility with Vim 5.x only. *synload-2* | |
| 308 | | |
| 309 +- Do ":filetype on", which does ":runtime! filetype.vim". It loads any | |
| 310 | filetype.vim files found. It should always Source | |
| 311 | $VIMRUNTIME/filetype.vim, which does the following. | |
| 312 | | | |
| 313 | +- Install autocmds based on suffix to set the 'filetype' option | |
| 314 | | This is where the connection between file name and file type is | |
| 315 | | made for known file types. *synload-3* | |
| 316 | | | |
| 317 | +- Source the user's optional file, from the *myfiletypefile* | |
| 318 | | variable. This is for backwards compatibility with Vim 5.x only. | |
| 319 | | *synload-4* | |
| 320 | | | |
| 321 | +- Install one autocommand which sources scripts.vim when no file | |
| 322 | | type was detected yet. *synload-5* | |
| 323 | | | |
| 324 | +- Source $VIMRUNTIME/menu.vim, to setup the Syntax menu. |menu.vim| | |
| 325 | | |
| 326 +- Install a FileType autocommand to set the 'syntax' option when a file | |
| 327 | type has been detected. *synload-6* | |
| 328 | | |
| 329 +- Execute syntax autocommands to start syntax highlighting for each | |
| 330 already loaded buffer. | |
| 331 | |
| 332 | |
| 333 Upon loading a file, Vim finds the relevant syntax file as follows: | |
| 334 | |
| 335 Loading the file triggers the BufReadPost autocommands. | |
| 336 | | |
| 337 +- If there is a match with one of the autocommands from |synload-3| | |
| 338 | (known file types) or |synload-4| (user's file types), the 'filetype' | |
| 339 | option is set to the file type. | |
| 340 | | |
| 341 +- The autocommand at |synload-5| is triggered. If the file type was not | |
| 342 | found yet, then scripts.vim is searched for in 'runtimepath'. This | |
| 343 | should always load $VIMRUNTIME/scripts.vim, which does the following. | |
| 344 | | | |
| 345 | +- Source the user's optional file, from the *myscriptsfile* | |
| 346 | | variable. This is for backwards compatibility with Vim 5.x only. | |
| 347 | | | |
| 348 | +- If the file type is still unknown, check the contents of the file, | |
| 349 | again with checks like "getline(1) =~ pattern" as to whether the | |
| 350 | file type can be recognized, and set 'filetype'. | |
| 351 | | |
| 352 +- When the file type was determined and 'filetype' was set, this | |
| 353 | triggers the FileType autocommand |synload-6| above. It sets | |
| 354 | 'syntax' to the determined file type. | |
| 355 | | |
| 356 +- When the 'syntax' option was set above, this triggers an autocommand | |
| 357 | from |synload-1| (and |synload-2|). This find the main syntax file in | |
| 358 | 'runtimepath', with this command: | |
| 359 | runtime! syntax/<name>.vim | |
| 360 | | |
| 361 +- Any other user installed FileType or Syntax autocommands are | |
| 362 triggered. This can be used to change the highlighting for a specific | |
| 363 syntax. | |
| 364 | |
| 365 ============================================================================== | |
| 366 4. Syntax file remarks *:syn-file-remarks* | |
| 367 | |
| 368 *b:current_syntax-variable* | |
| 369 Vim stores the name of the syntax that has been loaded in the | |
| 370 "b:current_syntax" variable. You can use this if you want to load other | |
| 371 settings, depending on which syntax is active. Example: > | |
| 372 :au BufReadPost * if b:current_syntax == "csh" | |
| 373 :au BufReadPost * do-some-things | |
| 374 :au BufReadPost * endif | |
| 375 | |
| 376 | |
| 377 2HTML *2html.vim* *convert-to-HTML* | |
| 378 | |
| 379 This is not a syntax file itself, but a script that converts the current | |
| 380 window into HTML. Vim opens a new window in which it builds the HTML file. | |
| 381 | |
| 382 You are not supposed to set the 'filetype' or 'syntax' option to "2html"! | |
| 383 Source the script to convert the current file: > | |
| 384 | |
| 385 :runtime! syntax/2html.vim | |
| 386 < | |
| 387 *:TOhtml* | |
| 388 Or use the ":TOhtml" user command. It is defined in a standard plugin. | |
| 389 ":TOhtml" also works with a range and in a Visual area: > | |
| 390 | |

| 486 TOhtml uses the current value of 'fileencoding' if set, or 'encoding' if not, | |
| 487 to determine the charset and 'fileencoding' of the HTML file. In general, this | |
| 488 works for the encodings mentioned specifically by name in |encoding-names|, but | |
| 489 TOhtml will only automatically use those encodings which are widely supported. | |
| 490 However, you can override this to support specific encodings that may not be | |
| 491 automatically detected by default. | |
| 492 | |
| 493 To overrule all automatic charset detection, set g:html_use_encoding to the | |
| 494 name of the charset to be used. TOhtml will try to determine the appropriate | |
| 495 'fileencoding' setting from the charset, but you may need to set it manually | |
| 496 if TOhtml cannot determine the encoding. It is recommended to set this | |
| 497 variable to something widely supported, like UTF-8, for anything you will be | |
| 498 hosting on a webserver: > | |
| 499 :let g:html_use_encoding = "UTF-8" | |
| 500 You can also use this option to omit the line that specifies the charset | |

| 2642 | 506 |
| 507 If you specify a charset with g:html_use_encoding for which TOhtml cannot | |
| 508 automatically detect the corresponding 'fileencoding' setting, you can use | |
| 509 g:html_encoding_override to allow TOhtml to detect the correct encoding. | |
| 510 This is a dictionary of charset-encoding pairs that will replace existing | |
| 511 pairs automatically detected by TOhtml, or supplement with new pairs. For | |
| 512 example, to allow TOhtml to detect the HTML charset "windows-1252" properly as | |
| 513 the encoding "8bit-cp1252", use: > | |
| 514 :let g:html_encoding_override = {'windows-1252': '8bit-cp1252'} | |
| 477 | 515 < |
| 2642 | 516 The g:html_charset_override is similar, it allows TOhtml to detect the HTML |
| 517 charset for any 'fileencoding' or 'encoding' which is not detected | |
| 518 automatically. You can also use it to override specific existing | |
| 519 encoding-charset pairs. For example, TOhtml will by default use UTF-8 for all | |
| 520 Unicode/UCS encodings. To use UTF-16 and UTF-32 instead, use: > | |
| 521 :let g:html_charset_override = {'ucs-4': 'UTF-32', 'utf-16': 'UTF-16'} | |
| 522 | |

536 - Some truly ancient browsers may not show the background colors. |

| 237 | 570 and the script syntax file name as second argument. Example: > |
| 7 | 571 |
| 572 :call AntSyntaxScript('perl', 'perl.vim') | |
| 573 | |
| 574 will install syntax perl highlighting for the following ant code > | |
| 575 | |
| 576 <script language = 'perl'><![CDATA[ | |
| 577 # everything inside is highlighted as perl | |
| 578 ]]></script> | |
| 579 | |

| 582 | |
| 501 | 583 APACHE *apache.vim* *ft-apache-syntax* |
| 7 | 584 |
| 585 The apache syntax file provides syntax highlighting depending on Apache HTTP | |
| 586 server version, by default for 1.3.x. Set "apache_version" to Apache version | |
| 587 (as a string) to get highlighting for another version. Example: > | |
| 588 | |
| 589 :let apache_version = "2.0" | |
| 590 < | |
| 591 | |
| 592 *asm.vim* *asmh8300.vim* *nasm.vim* *masm.vim* *asm68k* | |
| 501 | 593 ASSEMBLY *ft-asm-syntax* *ft-asmh8300-syntax* *ft-nasm-syntax* |
| 594 *ft-masm-syntax* *ft-asm68k-syntax* *fasm.vim* | |
| 7 | 595 |
| 596 Files matching "*.i" could be Progress or Assembly. If the automatic detection | |
| 597 doesn't work for you, or you don't edit Progress at all, use this in your | |
| 598 startup vimrc: > | |
| 599 :let filetype_i = "asm" | |
| 600 Replace "asm" with the type of assembly you use. | |
| 601 | |
| 602 There are many types of assembly languages that all use the same file name | |
| 603 extensions. Therefore you will have to select the type yourself, or add a | |
| 604 line in the assembly file that Vim will recognize. Currently these syntax | |
| 605 files are included: | |
| 606 asm GNU assembly (the default) | |
| 607 asm68k Motorola 680x0 assembly | |
| 608 asmh8300 Hitachi H-8300 version of GNU assembly | |
| 609 ia64 Intel Itanium 64 | |
| 610 fasm Flat assembly (http://flatassembler.net) | |
| 611 masm Microsoft assembly (probably works for any 80x86) | |
| 612 nasm Netwide assembly | |
| 613 tasm Turbo Assembly (with opcodes 80x86 up to Pentium, and | |
| 614 MMX) | |
| 615 pic PIC assembly (currently for PIC16F84) | |
| 616 | |
| 617 The most flexible is to add a line in your assembly file containing: > | |

| 624 b:asmsyntax variable: > | |
| 1624 | 625 :let b:asmsyntax = "nasm" |
| 7 | 626 |
| 627 If b:asmsyntax is not set, either automatically or by hand, then the value of | |
| 628 the global variable asmsyntax is used. This can be seen as a default assembly | |
| 629 language: > | |
| 1624 | 630 :let asmsyntax = "nasm" |

| 501 | 649 ASPPERL and ASPVBS *ft-aspperl-syntax* *ft-aspvbs-syntax* |
| 7 | 650 |
| 651 *.asp and *.asa files could be either Perl or Visual Basic script. Since it's | |
| 652 hard to detect this you can set two global variables to tell Vim what you are | |
| 653 using. For Perl script use: > | |
| 654 :let g:filetype_asa = "aspperl" | |
| 655 :let g:filetype_asp = "aspperl" | |
| 656 For Visual Basic use: > | |
| 657 :let g:filetype_asa = "aspvbs" | |
| 658 :let g:filetype_asp = "aspvbs" | |
| 659 | |
| 660 | |
| 856 | 661 BAAN *baan.vim* *baan-syntax* |
| 844 | 662 |
| 663 The baan.vim gives syntax support for BaanC of release BaanIV upto SSA ERP LN | |
| 664 for both 3 GL and 4 GL programming. Large number of standard defines/constants | |
| 665 are supported. | |
| 666 | |
| 667 Some special violation of coding standards will be signalled when one specify | |
| 668 in ones |.vimrc|: > | |
| 669 let baan_code_stds=1 | |
| 670 | |
| 671 *baan-folding* | |
| 672 | |
| 673 Syntax folding can be enabled at various levels through the variables | |
| 674 mentioned below (Set those in your |.vimrc|). The more complex folding on | |
| 675 source blocks and SQL can be CPU intensive. | |
| 676 | |
| 677 To allow any folding and enable folding at function level use: > | |
| 678 let baan_fold=1 | |
| 679 Folding can be enabled at source block level as if, while, for ,... The | |
| 680 indentation preceding the begin/end keywords has to match (spaces are not | |
| 681 considered equal to a tab). > | |
| 682 let baan_fold_block=1 | |
| 683 Folding can be enabled for embedded SQL blocks as SELECT, SELECTDO, | |
| 856 | 684 SELECTEMPTY, ... The indentation preceding the begin/end keywords has to |
| 844 | 685 match (spaces are not considered equal to a tab). > |
| 686 let baan_fold_sql=1 | |
| 856 | 687 Note: Block folding can result in many small folds. It is suggested to |:set| |
| 844 | 688 the options 'foldminlines' and 'foldnestmax' in |.vimrc| or use |:setlocal| in |
| 689 .../after/syntax/baan.vim (see |after-directory|). Eg: > | |
| 690 set foldminlines=5 | |
| 691 set foldnestmax=6 | |
| 692 | |
| 693 | |
| 501 | 694 BASIC *basic.vim* *vb.vim* *ft-basic-syntax* *ft-vb-syntax* |
| 7 | 695 |
| 696 Both Visual Basic and "normal" basic use the extension ".bas". To detect | |
| 697 which one should be used, Vim checks for the string "VB_Name" in the first | |
| 698 five lines of the file. If it is not found, filetype will be "basic", | |
| 699 otherwise "vb". Files with the ".frm" extension will always be seen as Visual | |
| 700 Basic. | |
| 701 | |
| 702 | |
| 501 | 703 C *c.vim* *ft-c-syntax* |
| 7 | 704 |
| 705 A few things in C highlighting are optional. To enable them assign any value | |
| 706 to the respective variable. Example: > | |
| 1624 | 707 :let c_comment_strings = 1 |
| 7 | 708 To disable them use ":unlet". Example: > |
| 709 :unlet c_comment_strings | |
| 710 | |
| 711 Variable Highlight ~ | |
| 712 c_gnu GNU gcc specific items | |
| 713 c_comment_strings strings and numbers inside a comment | |
| 714 c_space_errors trailing white space and spaces before a <Tab> | |
| 715 c_no_trail_space_error ... but no trailing spaces | |
| 716 c_no_tab_space_error ... but no spaces before a <Tab> | |
| 717 c_no_bracket_error don't highlight {}; inside [] as errors | |
| 140 | 718 c_no_curly_error don't highlight {}; inside [] and () as errors; |
| 719 except { and } in first column | |
| 1624 | 720 c_curly_error highlight a missing }; this forces syncing from the |
| 721 start of the file, can be slow | |
| 7 | 722 c_no_ansi don't do standard ANSI types and constants |
| 723 c_ansi_typedefs ... but do standard ANSI types | |
| 724 c_ansi_constants ... but do standard ANSI constants | |
| 725 c_no_utf don't highlight \u and \U in strings | |
| 726 c_syntax_for_h use C syntax for *.h files, instead of C++ | |
| 727 c_no_if0 don't highlight "#if 0" blocks as comments | |
| 728 c_no_cformat don't highlight %-formats in strings | |
| 729 c_no_c99 don't highlight C99 standard items | |
| 730 | |
| 36 | 731 When 'foldmethod' is set to "syntax" then /* */ comments and { } blocks will |
| 732 become a fold. If you don't want comments to become a fold use: > | |
| 733 :let c_no_comment_fold = 1 | |
| 842 | 734 "#if 0" blocks are also folded, unless: > |
| 735 :let c_no_if0_fold = 1 | |
| 36 | 736 |
| 7 | 737 If you notice highlighting errors while scrolling backwards, which are fixed |
| 738 when redrawing with CTRL-L, try setting the "c_minlines" internal variable | |
| 739 to a larger number: > | |
| 740 :let c_minlines = 100 | |
| 741 This will make the syntax synchronization start 100 lines before the first | |
| 742 displayed line. The default value is 50 (15 when c_no_if0 is set). The | |
| 743 disadvantage of using a larger number is that redrawing can become slow. | |
| 744 | |
| 745 When using the "#if 0" / "#endif" comment highlighting, notice that this only | |
| 746 works when the "#if 0" is within "c_minlines" from the top of the window. If | |
| 747 you have a long "#if 0" construct it will not be highlighted correctly. | |
| 748 | |
| 749 To match extra items in comments, use the cCommentGroup cluster. | |
| 750 Example: > | |
| 751 :au Syntax c call MyCadd() | |
| 752 :function MyCadd() | |
| 753 : syn keyword cMyItem contained Ni | |
| 754 : syn cluster cCommentGroup add=cMyItem | |
| 755 : hi link cMyItem Title | |
| 756 :endfun | |
| 757 | |
| 758 ANSI constants will be highlighted with the "cConstant" group. This includes | |
| 759 "NULL", "SIG_IGN" and others. But not "TRUE", for example, because this is | |
| 760 not in the ANSI standard. If you find this confusing, remove the cConstant | |
| 761 highlighting: > | |
| 762 :hi link cConstant NONE | |
| 763 | |
| 764 If you see '{' and '}' highlighted as an error where they are OK, reset the | |
| 765 highlighting for cErrInParen and cErrInBracket. | |
| 766 | |
| 767 If you want to use folding in your C files, you can add these lines in a file | |

| 777 | |

| 785 Chill syntax highlighting is similar to C. See |c.vim| for all the settings | |
| 786 that are available. Additionally there is: | |
| 787 | |
| 788 chill_space_errors like c_space_errors | |

| 790 chill_minlines like c_minlines | |

| 501 | 793 CHANGELOG *changelog.vim* *ft-changelog-syntax* |
| 7 | 794 |
| 795 ChangeLog supports highlighting spaces at the start of a line. | |
| 796 If you do not like this, add following line to your .vimrc: > | |
| 797 let g:changelog_spacing_errors = 0 | |
| 798 This works the next time you edit a changelog file. You can also use | |
| 799 "b:changelog_spacing_errors" to set this per buffer (before loading the syntax | |
| 800 file). | |
| 801 | |
| 802 You can change the highlighting used, e.g., to flag the spaces as an error: > | |
| 803 :hi link ChangelogError Error | |
| 804 Or to avoid the highlighting: > | |
| 805 :hi link ChangelogError NONE | |
| 806 This works immediately. | |

| 501 | 809 COBOL *cobol.vim* *ft-cobol-syntax* |
| 7 | 810 |
| 811 COBOL highlighting has different needs for legacy code than it does for fresh | |
| 812 development. This is due to differences in what is being done (maintenance | |
| 813 versus development) and other factors. To enable legacy code highlighting, | |
| 814 add this line to your .vimrc: > | |

| 7 | 821 |
| 237 | 822 The ColdFusion has its own version of HTML comments. To turn on ColdFusion |
| 7 | 823 comment highlighting, add the following line to your startup file: > |
| 824 | |
| 825 :let html_wrong_comments = 1 | |
| 826 | |
| 827 The ColdFusion syntax file is based on the HTML syntax file. | |
| 828 | |
| 829 | |
| 501 | 830 CSH *csh.vim* *ft-csh-syntax* |
| 7 | 831 |
| 832 This covers the shell named "csh". Note that on some systems tcsh is actually | |
| 833 used. | |
| 834 | |
| 835 Detecting whether a file is csh or tcsh is notoriously hard. Some systems | |
| 836 symlink /bin/csh to /bin/tcsh, making it almost impossible to distinguish | |
| 837 between csh and tcsh. In case VIM guesses wrong you can set the | |
| 838 "filetype_csh" variable. For using csh: > | |
| 839 | |
| 840 :let filetype_csh = "csh" | |
| 841 | |
| 842 For using tcsh: > | |
| 843 | |
| 844 :let filetype_csh = "tcsh" | |
| 845 | |
| 846 Any script with a tcsh extension or a standard tcsh filename (.tcshrc, | |
| 847 tcsh.tcshrc, tcsh.login) will have filetype tcsh. All other tcsh/csh scripts | |
| 237 | 848 will be classified as tcsh, UNLESS the "filetype_csh" variable exists. If the |
| 7 | 849 "filetype_csh" variable exists, the filetype will be set to the value of the |
| 850 variable. | |
| 851 | |
| 852 | |
| 501 | 853 CYNLIB *cynlib.vim* *ft-cynlib-syntax* |
| 7 | 854 |
| 855 Cynlib files are C++ files that use the Cynlib class library to enable | |
| 237 | 856 hardware modelling and simulation using C++. Typically Cynlib files have a .cc |
| 7 | 857 or a .cpp extension, which makes it very difficult to distinguish them from a |
| 237 | 858 normal C++ file. Thus, to enable Cynlib highlighting for .cc files, add this |
| 7 | 859 line to your .vimrc file: > |
| 860 | |
| 861 :let cynlib_cyntax_for_cc=1 | |
| 862 | |
| 863 Similarly for cpp files (this extension is only usually used in Windows) > | |
| 864 | |
| 865 :let cynlib_cyntax_for_cpp=1 | |
| 866 | |
| 867 To disable these again, use this: > | |

| 501 | 892 DIRCOLORS *dircolors.vim* *ft-dircolors-syntax* |
| 7 | 893 |
| 894 The dircolors utility highlighting definition has one option. It exists to | |
| 895 provide compatibility with the Slackware GNU/Linux distributions version of | |
| 896 the command. It adds a few keywords that are generally ignored by most | |
| 897 versions. On Slackware systems, however, the utility accepts the keywords and | |
| 898 uses them for processing. To enable the Slackware keywords add the following | |
| 899 line to your startup file: > | |
| 900 let dircolors_is_slackware = 1 | |

| 905 DOCBOOK SGML *docbksgml.vim* *ft-docbksgml-syntax* | |
| 7 | 906 |
| 907 There are two types of DocBook files: SGML and XML. To specify what type you | |
| 908 are using the "b:docbk_type" variable should be set. Vim does this for you | |
| 909 automatically if it can recognize the type. When Vim can't guess it the type | |
| 910 defaults to XML. | |
| 911 You can set the type manually: > | |
| 912 :let docbk_type = "sgml" | |
| 913 or: > | |
| 914 :let docbk_type = "xml" | |
| 915 You need to do this before loading the syntax file, which is complicated. | |
| 916 Simpler is setting the filetype to "docbkxml" or "docbksgml": > | |
| 917 :set filetype=docbksgml | |
| 918 or: > | |
| 919 :set filetype=docbkxml | |
| 920 | |
| 921 | |
| 501 | 922 DOSBATCH *dosbatch.vim* *ft-dosbatch-syntax* |
| 7 | 923 |
| 924 There is one option with highlighting DOS batch files. This covers new | |
| 925 extensions to the Command Interpreter introduced with Windows 2000 and | |
| 926 is controlled by the variable dosbatch_cmdextversion. For Windows NT | |
| 927 this should have the value 1, and for Windows 2000 it should be 2. | |
| 928 Select the version you want with the following line: > | |
| 929 | |
| 15 | 930 :let dosbatch_cmdextversion = 1 |
| 7 | 931 |
| 932 If this variable is not defined it defaults to a value of 2 to support | |
| 933 Windows 2000. | |
| 934 | |
| 15 | 935 A second option covers whether *.btm files should be detected as type |
| 237 | 936 "dosbatch" (MS-DOS batch files) or type "btm" (4DOS batch files). The latter |
| 937 is used by default. You may select the former with the following line: > | |
| 15 | 938 |
| 939 :let g:dosbatch_syntax_for_btm = 1 | |
| 940 | |
| 941 If this variable is undefined or zero, btm syntax is selected. | |
| 942 | |
| 943 | |
| 832 | 944 DOXYGEN *doxygen.vim* *doxygen-syntax* |
| 945 | |
| 946 Doxygen generates code documentation using a special documentation format | |
| 1698 | 947 (similar to Javadoc). This syntax script adds doxygen highlighting to c, cpp, |
| 948 idl and php files, and should also work with java. | |
| 832 | 949 |
| 1224 | 950 There are a few of ways to turn on doxygen formatting. It can be done |
| 951 explicitly or in a modeline by appending '.doxygen' to the syntax of the file. | |
| 952 Example: > | |
| 832 | 953 :set syntax=c.doxygen |
| 954 or > | |
| 955 // vim:syntax=c.doxygen | |
| 956 | |
| 2520 | 957 It can also be done automatically for C, C++, C# and IDL files by setting the |
| 1224 | 958 global or buffer-local variable load_doxygen_syntax. This is done by adding |
| 959 the following to your .vimrc. > | |
| 832 | 960 :let g:load_doxygen_syntax=1 |

| 501 | 989 DTD *dtd.vim* *ft-dtd-syntax* |
| 7 | 990 |
| 237 | 991 The DTD syntax highlighting is case sensitive by default. To disable |
| 7 | 992 case-sensitive highlighting, add the following line to your startup file: > |
| 993 | |
| 994 :let dtd_ignore_case=1 | |
| 995 | |
| 237 | 996 The DTD syntax file will highlight unknown tags as errors. If |
| 7 | 997 this is annoying, it can be turned off by setting: > |
| 998 | |
| 999 :let dtd_no_tag_errors=1 | |
| 1000 | |
| 1001 before sourcing the dtd.vim syntax file. | |
| 1002 Parameter entity names are highlighted in the definition using the | |
| 1003 'Type' highlighting group and 'Comment' for punctuation and '%'. | |
| 1004 Parameter entity instances are highlighted using the 'Constant' | |
| 1005 highlighting group and the 'Type' highlighting group for the | |
| 237 | 1006 delimiters % and ;. This can be turned off by setting: > |
| 7 | 1007 |
| 1008 :let dtd_no_param_entities=1 | |
| 1009 | |
| 1010 The DTD syntax file is also included by xml.vim to highlight included dtd's. | |
| 1011 | |
| 1012 | |
| 501 | 1013 EIFFEL *eiffel.vim* *ft-eiffel-syntax* |
| 7 | 1014 |
| 1015 While Eiffel is not case-sensitive, its style guidelines are, and the | |
| 237 | 1016 syntax highlighting file encourages their use. This also allows to |
| 1017 highlight class names differently. If you want to disable case-sensitive | |
| 7 | 1018 highlighting, add the following line to your startup file: > |
| 1019 | |
| 1020 :let eiffel_ignore_case=1 | |
| 1021 | |
| 1022 Case still matters for class names and TODO marks in comments. | |
| 1023 | |
| 1024 Conversely, for even stricter checks, add one of the following lines: > | |
| 1025 | |
| 1026 :let eiffel_strict=1 | |
| 1027 :let eiffel_pedantic=1 | |
| 1028 | |
| 1029 Setting eiffel_strict will only catch improper capitalization for the | |
| 1030 five predefined words "Current", "Void", "Result", "Precursor", and | |
| 1031 "NONE", to warn against their accidental use as feature or class names. | |
| 1032 | |
| 1033 Setting eiffel_pedantic will enforce adherence to the Eiffel style | |
| 1034 guidelines fairly rigorously (like arbitrary mixes of upper- and | |
| 1035 lowercase letters as well as outdated ways to capitalize keywords). | |
| 1036 | |
| 1037 If you want to use the lower-case version of "Current", "Void", | |
| 1038 "Result", and "Precursor", you can use > | |
| 1039 | |
| 1040 :let eiffel_lower_case_predef=1 | |
| 1041 | |
| 1042 instead of completely turning case-sensitive highlighting off. | |
| 1043 | |
| 1044 Support for ISE's proposed new creation syntax that is already | |
| 1045 experimentally handled by some compilers can be enabled by: > | |
| 1046 | |
| 1047 :let eiffel_ise=1 | |
| 1048 | |
| 237 | 1049 Finally, some vendors support hexadecimal constants. To handle them, add > |
| 7 | 1050 |
| 1051 :let eiffel_hex_constants=1 | |
| 1052 | |
| 1053 to your startup file. | |
| 1054 | |
| 1055 | |
| 501 | 1056 ERLANG *erlang.vim* *ft-erlang-syntax* |
| 7 | 1057 |
| 1058 The erlang highlighting supports Erlang (ERicsson LANGuage). | |
| 1059 Erlang is case sensitive and default extension is ".erl". | |
| 1060 | |
| 1061 If you want to disable keywords highlighting, put in your .vimrc: > | |
| 1062 :let erlang_keywords = 1 | |
| 1063 If you want to disable built-in-functions highlighting, put in your | |
| 1064 .vimrc file: > | |
| 1065 :let erlang_functions = 1 | |
| 1066 If you want to disable special characters highlighting, put in | |
| 1067 your .vimrc: > | |
| 1068 :let erlang_characters = 1 | |
| 1069 | |
| 1070 | |
| 857 | 1071 FLEXWIKI *flexwiki.vim* *ft-flexwiki-syntax* |
| 1072 | |
| 1073 FlexWiki is an ASP.NET-based wiki package available at http://www.flexwiki.com | |
| 1074 | |
| 1075 Syntax highlighting is available for the most common elements of FlexWiki | |
| 1076 syntax. The associated ftplugin script sets some buffer-local options to make | |
| 1077 editing FlexWiki pages more convenient. FlexWiki considers a newline as the | |
| 1078 start of a new paragraph, so the ftplugin sets 'tw'=0 (unlimited line length), | |
| 1079 'wrap' (wrap long lines instead of using horizontal scrolling), 'linebreak' | |
| 1080 (to wrap at a character in 'breakat' instead of at the last char on screen), | |
| 1081 and so on. It also includes some keymaps that are disabled by default. | |
| 1082 | |
| 1083 If you want to enable the keymaps that make "j" and "k" and the cursor keys | |
| 1084 move up and down by display lines, add this to your .vimrc: > | |
| 1085 :let flexwiki_maps = 1 | |
| 1086 | |
| 1087 | |
| 501 | 1088 FORM *form.vim* *ft-form-syntax* |
| 7 | 1089 |
| 1090 The coloring scheme for syntax elements in the FORM file uses the default | |
| 1091 modes Conditional, Number, Statement, Comment, PreProc, Type, and String, | |
| 1275 | 1092 following the language specifications in 'Symbolic Manipulation with FORM' by |
| 7 | 1093 J.A.M. Vermaseren, CAN, Netherlands, 1991. |
| 1094 | |
| 1095 If you want include your own changes to the default colors, you have to | |
| 1096 redefine the following syntax groups: | |
| 1097 | |
| 1098 - formConditional | |
| 1099 - formNumber | |
| 1100 - formStatement | |
| 1101 - formHeaderStatement | |
| 1102 - formComment | |
| 1103 - formPreProc | |
| 1104 - formDirective | |
| 1105 - formType | |
| 1106 - formString | |
| 1107 | |
| 1108 Note that the form.vim syntax file implements FORM preprocessor commands and | |
| 1109 directives per default in the same syntax group. | |
| 1110 | |
| 1111 A predefined enhanced color mode for FORM is available to distinguish between | |
| 237 | 1112 header statements and statements in the body of a FORM program. To activate |
| 7 | 1113 this mode define the following variable in your vimrc file > |
| 1114 | |
| 1115 :let form_enhanced_color=1 | |
| 1116 | |
| 1117 The enhanced mode also takes advantage of additional color features for a dark | |
| 237 | 1118 gvim display. Here, statements are colored LightYellow instead of Yellow, and |
| 7 | 1119 conditionals are LightBlue for better distinction. |

| 501 | 1122 FORTRAN *fortran.vim* *ft-fortran-syntax* |
| 7 | 1123 |
| 1124 Default highlighting and dialect ~ | |
| 237 | 1125 Highlighting appropriate for f95 (Fortran 95) is used by default. This choice |
| 7 | 1126 should be appropriate for most users most of the time because Fortran 95 is a |
| 2398 | 1127 superset of Fortran 90 and almost a superset of Fortran 77. Support for |
| 1128 Fortran 2003 and Fortran 2008 features has been introduced and is | |

1129 automatically available in the default (f95) highlighting. |
| 7 | 1130 |
| 1131 Fortran source code form ~ | |
| 237 | 1132 Fortran 9x code can be in either fixed or free source form. Note that the |
| 7 | 1133 syntax highlighting will not be correct if the form is incorrectly set. |
| 1134 | |
| 1135 When you create a new fortran file, the syntax script assumes fixed source | |
| 237 | 1136 form. If you always use free source form, then > |
| 7 | 1137 :let fortran_free_source=1 |
| 237 | 1138 in your .vimrc prior to the :syntax on command. If you always use fixed source |
| 7 | 1139 form, then > |
| 1140 :let fortran_fixed_source=1 | |
| 1141 in your .vimrc prior to the :syntax on command. | |
| 1142 | |
| 1143 If the form of the source code depends upon the file extension, then it is | |
| 237 | 1144 most convenient to set fortran_free_source in a ftplugin file. For more |
| 1145 information on ftplugin files, see |ftplugin|. For example, if all your | |
| 7 | 1146 fortran files with an .f90 extension are written in free source form and the |
| 1147 rest in fixed source form, add the following code to your ftplugin file > | |
| 1148 let s:extfname = expand("%:e") | |
| 1149 if s:extfname ==? "f90" | |
| 1150 let fortran_free_source=1 | |
| 1151 unlet! fortran_fixed_source | |
| 1152 else | |
| 1153 let fortran_fixed_source=1 | |
| 1154 unlet! fortran_free_source | |
| 1155 endif | |
| 1156 Note that this will work only if the "filetype plugin indent on" command | |
| 1157 precedes the "syntax on" command in your .vimrc file. | |
| 1158 | |
| 1159 When you edit an existing fortran file, the syntax script will assume free | |
| 1160 source form if the fortran_free_source variable has been set, and assumes | |
| 237 | 1161 fixed source form if the fortran_fixed_source variable has been set. If |
| 7 | 1162 neither of these variables have been set, the syntax script attempts to |
| 1163 determine which source form has been used by examining the first five columns | |
| 819 | 1164 of the first 250 lines of your file. If no signs of free source form are |
| 237 | 1165 detected, then the file is assumed to be in fixed source form. The algorithm |
| 1166 should work in the vast majority of cases. In some cases, such as a file that | |
| 819 | 1167 begins with 250 or more full-line comments, the script may incorrectly decide |
| 237 | 1168 that the fortran code is in fixed form. If that happens, just add a |
| 7 | 1169 non-comment statement beginning anywhere in the first five columns of the |
| 1170 first twenty five lines, save (:w) and then reload (:e!) the file. | |
| 1171 | |
| 1172 Tabs in fortran files ~ | |
| 237 | 1173 Tabs are not recognized by the Fortran standards. Tabs are not a good idea in |
| 7 | 1174 fixed format fortran source code which requires fixed column boundaries. |
| 237 | 1175 Therefore, tabs are marked as errors. Nevertheless, some programmers like |
| 1176 using tabs. If your fortran files contain tabs, then you should set the | |
| 7 | 1177 variable fortran_have_tabs in your .vimrc with a command such as > |
| 1178 :let fortran_have_tabs=1 | |
| 237 | 1179 placed prior to the :syntax on command. Unfortunately, the use of tabs will |
| 7 | 1180 mean that the syntax file will not be able to detect incorrect margins. |
| 1181 | |
| 1182 Syntax folding of fortran files ~ | |
| 1183 If you wish to use foldmethod=syntax, then you must first set the variable | |
| 1184 fortran_fold with a command such as > | |
| 1185 :let fortran_fold=1 | |
| 1186 to instruct the syntax script to define fold regions for program units, that | |
| 1187 is main programs starting with a program statement, subroutines, function | |
| 237 | 1188 subprograms, block data subprograms, interface blocks, and modules. If you |
| 7 | 1189 also set the variable fortran_fold_conditionals with a command such as > |
| 1190 :let fortran_fold_conditionals=1 | |
| 1191 then fold regions will also be defined for do loops, if blocks, and select | |
| 237 | 1192 case constructs. If you also set the variable |
| 7 | 1193 fortran_fold_multilinecomments with a command such as > |
| 1194 :let fortran_fold_multilinecomments=1 | |
| 1195 then fold regions will also be defined for three or more consecutive comment | |
| 237 | 1196 lines. Note that defining fold regions can be slow for large files. |
| 7 | 1197 |
| 1198 If fortran_fold, and possibly fortran_fold_conditionals and/or | |
| 1199 fortran_fold_multilinecomments, have been set, then vim will fold your file if | |
| 237 | 1200 you set foldmethod=syntax. Comments or blank lines placed between two program |
| 7 | 1201 units are not folded because they are seen as not belonging to any program |
| 1202 unit. | |
| 1203 | |
| 1204 More precise fortran syntax ~ | |
| 1205 If you set the variable fortran_more_precise with a command such as > | |
| 1206 :let fortran_more_precise=1 | |
| 237 | 1207 then the syntax coloring will be more precise but slower. In particular, |
| 7 | 1208 statement labels used in do, goto and arithmetic if statements will be |
| 1209 recognized, as will construct names at the end of a do, if, select or forall | |
| 1210 construct. | |
| 1211 | |
| 1212 Non-default fortran dialects ~ | |
| 1213 The syntax script supports five Fortran dialects: f95, f90, f77, the Lahey | |
| 1214 subset elf90, and the Imagine1 subset F. | |
| 1215 | |
| 1216 If you use f77 with extensions, even common ones like do/enddo loops, do/while | |
| 1217 loops and free source form that are supported by most f77 compilers including | |
| 1218 g77 (GNU Fortran), then you will probably find the default highlighting | |
| 237 | 1219 satisfactory. However, if you use strict f77 with no extensions, not even free |
| 7 | 1220 source form or the MIL STD 1753 extensions, then the advantages of setting the |
| 1221 dialect to f77 are that names such as SUM are recognized as user variable | |
| 1222 names and not highlighted as f9x intrinsic functions, that obsolete constructs | |
| 1223 such as ASSIGN statements are not highlighted as todo items, and that fixed | |
| 1224 source form will be assumed. | |
| 1225 | |
| 1226 If you use elf90 or F, the advantage of setting the dialect appropriately is | |
| 1227 that f90 features excluded from these dialects will be highlighted as todo | |
| 1228 items and that free source form will be assumed as required for these | |
| 1229 dialects. | |
| 1230 | |
| 237 | 1231 The dialect can be selected by setting the variable fortran_dialect. The |
| 7 | 1232 permissible values of fortran_dialect are case-sensitive and must be "f95", |
| 237 | 1233 "f90", "f77", "elf" or "F". Invalid values of fortran_dialect are ignored. |
| 7 | 1234 |
| 1235 If all your fortran files use the same dialect, set fortran_dialect in your | |
| 237 | 1236 .vimrc prior to your syntax on statement. If the dialect depends upon the file |
| 1237 extension, then it is most convenient to set it in a ftplugin file. For more | |
| 1238 information on ftplugin files, see |ftplugin|. For example, if all your | |
| 7 | 1239 fortran files with an .f90 extension are written in the elf subset, your |
| 1240 ftplugin file should contain the code > | |
| 1241 let s:extfname = expand("%:e") | |
| 1242 if s:extfname ==? "f90" | |
| 1243 let fortran_dialect="elf" | |
| 1244 else | |
| 1245 unlet! fortran_dialect | |
| 1246 endif | |
| 1247 Note that this will work only if the "filetype plugin indent on" command | |
| 1248 precedes the "syntax on" command in your .vimrc file. | |
| 1249 | |
| 1250 Finer control is necessary if the file extension does not uniquely identify | |
| 237 | 1251 the dialect. You can override the default dialect, on a file-by-file basis, by |
| 7 | 1252 including a comment with the directive "fortran_dialect=xx" (where xx=f77 or |
| 237 | 1253 elf or F or f90 or f95) in one of the first three lines in your file. For |
| 7 | 1254 example, your older .f files may be written in extended f77 but your newer |
| 1255 ones may be F codes, and you would identify the latter by including in the | |
| 1256 first three lines of those files a Fortran comment of the form > | |
| 1257 ! fortran_dialect=F | |
| 1258 F overrides elf if both directives are present. | |
| 1259 | |
| 1260 Limitations ~ | |
| 237 | 1261 Parenthesis checking does not catch too few closing parentheses. Hollerith |
| 1262 strings are not recognized. Some keywords may be highlighted incorrectly | |
| 7 | 1263 because Fortran90 has no reserved words. |
| 1264 | |
| 501 | 1265 For further information related to fortran, see |ft-fortran-indent| and |
| 1266 |ft-fortran-plugin|. | |
| 1267 | |
| 1268 | |
| 1269 FVWM CONFIGURATION FILES *fvwm.vim* *ft-fvwm-syntax* | |
| 7 | 1270 |
| 1271 In order for Vim to recognize Fvwm configuration files that do not match | |
| 1272 the patterns *fvwmrc* or *fvwm2rc* , you must put additional patterns | |
| 1273 appropriate to your system in your myfiletypes.vim file. For these | |
| 1274 patterns, you must set the variable "b:fvwm_version" to the major version | |
| 1275 number of Fvwm, and the 'filetype' option to fvwm. | |
| 1276 | |
| 1277 For example, to make Vim identify all files in /etc/X11/fvwm2/ | |
| 1278 as Fvwm2 configuration files, add the following: > | |
| 1279 | |
| 1280 :au! BufNewFile,BufRead /etc/X11/fvwm2/* let b:fvwm_version = 2 | | |
| 1281 \ set filetype=fvwm | |
| 1282 | |
| 1283 If you'd like Vim to highlight all valid color names, tell it where to | |
| 1284 find the color database (rgb.txt) on your system. Do this by setting | |
| 1285 "rgb_file" to its location. Assuming your color database is located | |
| 1286 in /usr/X11/lib/X11/, you should add the line > | |
| 1287 | |
| 1288 :let rgb_file = "/usr/X11/lib/X11/rgb.txt" | |
| 1289 | |
| 1290 to your .vimrc file. | |
| 1291 | |
| 1292 | |
| 501 | 1293 GSP *gsp.vim* *ft-gsp-syntax* |
| 7 | 1294 |
| 1295 The default coloring style for GSP pages is defined by |html.vim|, and | |
| 1296 the coloring for java code (within java tags or inline between backticks) | |
| 1297 is defined by |java.vim|. The following HTML groups defined in |html.vim| | |
| 1298 are redefined to incorporate and highlight inline java code: | |
| 1299 | |
| 1300 htmlString | |
| 1301 htmlValue | |
| 1302 htmlEndTag | |
| 1303 htmlTag | |
| 1304 htmlTagN | |
| 1305 | |
| 1306 Highlighting should look fine most of the places where you'd see inline | |
| 1307 java code, but in some special cases it may not. To add another HTML | |
| 1308 group where you will have inline java code where it does not highlight | |
| 1309 correctly, just copy the line you want from |html.vim| and add gspJava | |
| 1310 to the contains clause. | |
| 1311 | |
| 1312 The backticks for inline java are highlighted according to the htmlError | |
| 1313 group to make them easier to see. | |
| 1314 | |
| 1315 | |
| 501 | 1316 GROFF *groff.vim* *ft-groff-syntax* |
| 7 | 1317 |
| 1318 The groff syntax file is a wrapper for |nroff.vim|, see the notes | |
| 237 | 1319 under that heading for examples of use and configuration. The purpose |
| 7 | 1320 of this wrapper is to set up groff syntax extensions by setting the |
| 1321 filetype from a |modeline| or in a personal filetype definitions file | |
| 1322 (see |filetype.txt|). | |
| 1323 | |
| 1324 | |
| 501 | 1325 HASKELL *haskell.vim* *lhaskell.vim* *ft-haskell-syntax* |
| 7 | 1326 |
| 1327 The Haskell syntax files support plain Haskell code as well as literate | |
| 237 | 1328 Haskell code, the latter in both Bird style and TeX style. The Haskell |
| 7 | 1329 syntax highlighting will also highlight C preprocessor directives. |
| 1330 | |
| 1331 If you want to highlight delimiter characters (useful if you have a | |
| 1332 light-coloured background), add to your .vimrc: > | |
| 1333 :let hs_highlight_delimiters = 1 | |
| 1334 To treat True and False as keywords as opposed to ordinary identifiers, | |
| 1335 add: > | |
| 1336 :let hs_highlight_boolean = 1 | |
| 1337 To also treat the names of primitive types as keywords: > | |
| 1338 :let hs_highlight_types = 1 | |
| 1339 And to treat the names of even more relatively common types as keywords: > | |
| 1340 :let hs_highlight_more_types = 1 | |
| 1341 If you want to highlight the names of debugging functions, put in | |
| 1342 your .vimrc: > | |
| 1343 :let hs_highlight_debug = 1 | |
| 1344 | |
| 1345 The Haskell syntax highlighting also highlights C preprocessor | |
| 1346 directives, and flags lines that start with # but are not valid | |
| 237 | 1347 directives as erroneous. This interferes with Haskell's syntax for |
| 1348 operators, as they may start with #. If you want to highlight those | |
| 7 | 1349 as operators as opposed to errors, put in your .vimrc: > |
| 1350 :let hs_allow_hash_operator = 1 | |
| 1351 | |
| 1352 The syntax highlighting for literate Haskell code will try to | |
| 1353 automatically guess whether your literate Haskell code contains | |
| 1354 TeX markup or not, and correspondingly highlight TeX constructs | |
| 237 | 1355 or nothing at all. You can override this globally by putting |
| 7 | 1356 in your .vimrc > |
| 1357 :let lhs_markup = none | |
| 1358 for no highlighting at all, or > | |
| 1359 :let lhs_markup = tex | |
| 1360 to force the highlighting to always try to highlight TeX markup. | |
| 1361 For more flexibility, you may also use buffer local versions of | |
| 1362 this variable, so e.g. > | |
| 1363 :let b:lhs_markup = tex | |
| 237 | 1364 will force TeX highlighting for a particular buffer. It has to be |
| 7 | 1365 set before turning syntax highlighting on for the buffer or |
| 1366 loading a file. | |
| 1367 | |
| 1368 | |
| 501 | 1369 HTML *html.vim* *ft-html-syntax* |
| 7 | 1370 |
| 1371 The coloring scheme for tags in the HTML file works as follows. | |
| 1372 | |
| 1373 The <> of opening tags are colored differently than the </> of a closing tag. | |
| 1374 This is on purpose! For opening tags the 'Function' color is used, while for | |
| 1375 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
| 1376 defined for you) | |
| 1377 | |
| 1378 Known tag names are colored the same way as statements in C. Unknown tag | |
| 1379 names are colored with the same color as the <> or </> respectively which | |
| 1380 makes it easy to spot errors | |
| 1381 | |
| 237 | 1382 Note that the same is true for argument (or attribute) names. Known attribute |
| 7 | 1383 names are colored differently than unknown ones. |
| 1384 | |
| 237 | 1385 Some HTML tags are used to change the rendering of text. The following tags |
| 7 | 1386 are recognized by the html.vim syntax coloring file and change the way normal |
| 1387 text is shown: <B> <I> <U> <EM> <STRONG> (<EM> is used as an alias for <I>, | |
| 1388 while <STRONG> as an alias for <B>), <H1> - <H6>, <HEAD>, <TITLE> and <A>, but | |
| 237 | 1389 only if used as a link (that is, it must include a href as in |
| 1224 | 1390 <A href="somefile.html">). |
| 7 | 1391 |
| 1392 If you want to change how such text is rendered, you must redefine the | |
| 1393 following syntax groups: | |
| 1394 | |
| 1395 - htmlBold | |
| 1396 - htmlBoldUnderline | |
| 1397 - htmlBoldUnderlineItalic | |
| 1398 - htmlUnderline | |
| 1399 - htmlUnderlineItalic | |
| 1400 - htmlItalic | |
| 1401 - htmlTitle for titles | |
| 1402 - htmlH1 - htmlH6 for headings | |
| 1403 | |
| 1404 To make this redefinition work you must redefine them all with the exception | |
| 1405 of the last two (htmlTitle and htmlH[1-6], which are optional) and define the | |
| 1406 following variable in your vimrc (this is due to the order in which the files | |
| 1407 are read during initialization) > | |
| 1408 :let html_my_rendering=1 | |
| 1409 | |
| 1410 If you'd like to see an example download mysyntax.vim at | |
| 1411 http://www.fleiner.com/vim/download.html | |
| 1412 | |
| 1413 You can also disable this rendering by adding the following line to your | |
| 1414 vimrc file: > | |
| 1415 :let html_no_rendering=1 | |
| 1416 | |
| 1417 HTML comments are rather special (see an HTML reference document for the | |
| 1418 details), and the syntax coloring scheme will highlight all errors. | |
| 1419 However, if you prefer to use the wrong style (starts with <!-- and | |
| 1420 ends with --!>) you can define > | |
| 1421 :let html_wrong_comments=1 | |
| 1422 | |
| 1423 JavaScript and Visual Basic embedded inside HTML documents are highlighted as | |
| 1424 'Special' with statements, comments, strings and so on colored as in standard | |
| 237 | 1425 programming languages. Note that only JavaScript and Visual Basic are currently |
| 7 | 1426 supported, no other scripting language has been added yet. |
| 1427 | |
| 1428 Embedded and inlined cascading style sheets (CSS) are highlighted too. | |
| 1429 | |
| 237 | 1430 There are several html preprocessor languages out there. html.vim has been |
| 1431 written such that it should be trivial to include it. To do so add the | |
| 7 | 1432 following two lines to the syntax coloring file for that language |
| 1433 (the example comes from the asp.vim file): | |
| 1434 | |
| 1435 runtime! syntax/html.vim | |
| 1436 syn cluster htmlPreproc add=asp | |
| 1437 | |
| 1438 Now you just need to make sure that you add all regions that contain | |
| 1439 the preprocessor language to the cluster htmlPreproc. | |
| 1440 | |
| 1441 | |
| 501 | 1442 HTML/OS (by Aestiva) *htmlos.vim* *ft-htmlos-syntax* |
| 7 | 1443 |
| 1444 The coloring scheme for HTML/OS works as follows: | |
| 1445 | |
| 1446 Functions and variable names are the same color by default, because VIM | |
| 1447 doesn't specify different colors for Functions and Identifiers. To change | |
| 1448 this (which is recommended if you want function names to be recognizable in a | |
| 1449 different color) you need to add the following line to either your ~/.vimrc: > | |
| 1450 :hi Function term=underline cterm=bold ctermfg=LightGray | |
| 1451 | |
| 1452 Of course, the ctermfg can be a different color if you choose. | |
| 1453 | |
| 1454 Another issues that HTML/OS runs into is that there is no special filetype to | |
| 1455 signify that it is a file with HTML/OS coding. You can change this by opening | |
| 1456 a file and turning on HTML/OS syntax by doing the following: > | |
| 1457 :set syntax=htmlos | |
| 1458 | |
| 1459 Lastly, it should be noted that the opening and closing characters to begin a | |
| 1460 block of HTML/OS code can either be << or [[ and >> or ]], respectively. | |
| 1461 | |
| 1462 | |
| 501 | 1463 IA64 *ia64.vim* *intel-itanium* *ft-ia64-syntax* |
| 7 | 1464 |
| 1465 Highlighting for the Intel Itanium 64 assembly language. See |asm.vim| for | |
| 1466 how to recognize this filetype. | |
| 1467 | |
| 1468 To have *.inc files be recognized as IA64, add this to your .vimrc file: > | |
| 1469 :let g:filetype_inc = "ia64" | |
| 1470 | |
| 1471 | |
| 501 | 1472 INFORM *inform.vim* *ft-inform-syntax* |
| 7 | 1473 |
| 1474 Inform highlighting includes symbols provided by the Inform Library, as | |
| 1475 most programs make extensive use of it. If do not wish Library symbols | |
| 1476 to be highlighted add this to your vim startup: > | |
| 1477 :let inform_highlight_simple=1 | |
| 1478 | |
| 1479 By default it is assumed that Inform programs are Z-machine targeted, | |
| 1480 and highlights Z-machine assembly language symbols appropriately. If | |
| 1481 you intend your program to be targeted to a Glulx/Glk environment you | |
| 1482 need to add this to your startup sequence: > | |
| 1483 :let inform_highlight_glulx=1 | |
| 1484 | |
| 1485 This will highlight Glulx opcodes instead, and also adds glk() to the | |
| 1486 set of highlighted system functions. | |
| 1487 | |
| 1488 The Inform compiler will flag certain obsolete keywords as errors when | |
| 1489 it encounters them. These keywords are normally highlighted as errors | |
| 1490 by Vim. To prevent such error highlighting, you must add this to your | |
| 1491 startup sequence: > | |
| 1492 :let inform_suppress_obsolete=1 | |
| 1493 | |
| 1494 By default, the language features highlighted conform to Compiler | |
| 1495 version 6.30 and Library version 6.11. If you are using an older | |
| 1496 Inform development environment, you may with to add this to your | |
| 1497 startup sequence: > | |
| 1498 :let inform_highlight_old=1 | |
| 1499 | |
| 829 | 1500 IDL *idl.vim* *idl-syntax* |
| 1501 | |
| 1502 IDL (Interface Definition Language) files are used to define RPC calls. In | |
| 1503 Microsoft land, this is also used for defining COM interfaces and calls. | |
| 1504 | |
| 1505 IDL's structure is simple enough to permit a full grammar based approach to | |
| 1506 rather than using a few heuristics. The result is large and somewhat | |
| 1224 | 1507 repetitive but seems to work. |
| 829 | 1508 |
| 1509 There are some Microsoft extensions to idl files that are here. Some of them | |
| 1510 are disabled by defining idl_no_ms_extensions. | |
| 1511 | |
| 1512 The more complex of the extensions are disabled by defining idl_no_extensions. | |
| 1513 | |
| 1514 Variable Effect ~ | |
| 1515 | |
| 1516 idl_no_ms_extensions Disable some of the Microsoft specific | |
| 1517 extensions | |
| 1518 idl_no_extensions Disable complex extensions | |
| 1519 idlsyntax_showerror Show IDL errors (can be rather intrusive, but | |
| 1520 quite helpful) | |
| 1521 idlsyntax_showerror_soft Use softer colours by default for errors | |
| 1522 | |
| 7 | 1523 |
| 501 | 1524 JAVA *java.vim* *ft-java-syntax* |
| 7 | 1525 |
| 1526 The java.vim syntax highlighting file offers several options: | |
| 1527 | |
| 1528 In Java 1.0.2 it was never possible to have braces inside parens, so this was | |
| 1529 flagged as an error. Since Java 1.1 this is possible (with anonymous | |
| 237 | 1530 classes), and therefore is no longer marked as an error. If you prefer the old |
| 7 | 1531 way, put the following line into your vim startup file: > |
| 1532 :let java_mark_braces_in_parens_as_errors=1 | |
| 1533 | |
| 1534 All identifiers in java.lang.* are always visible in all classes. To | |
| 1535 highlight them use: > | |
| 1536 :let java_highlight_java_lang_ids=1 | |
| 1537 | |
| 237 | 1538 You can also highlight identifiers of most standard Java packages if you |
| 7 | 1539 download the javaid.vim script at http://www.fleiner.com/vim/download.html. |
| 1540 If you prefer to only highlight identifiers of a certain package, say java.io | |
| 1541 use the following: > | |
| 1542 :let java_highlight_java_io=1 | |
| 1543 Check the javaid.vim file for a list of all the packages that are supported. | |
| 1544 | |
| 1545 Function names are not highlighted, as the way to find functions depends on | |
| 237 | 1546 how you write Java code. The syntax file knows two possible ways to highlight |
| 7 | 1547 functions: |
| 1548 | |
| 1549 If you write function declarations that are always indented by either | |
| 1550 a tab, 8 spaces or 2 spaces you may want to set > | |
| 1551 :let java_highlight_functions="indent" | |
| 1552 However, if you follow the Java guidelines about how functions and classes are | |
| 1553 supposed to be named (with respect to upper and lowercase), use > | |
| 1554 :let java_highlight_functions="style" | |
| 1555 If both options do not work for you, but you would still want function | |
| 1556 declarations to be highlighted create your own definitions by changing the | |
| 1557 definitions in java.vim or by creating your own java.vim which includes the | |
| 1558 original one and then adds the code to highlight functions. | |
| 1559 | |
| 237 | 1560 In Java 1.1 the functions System.out.println() and System.err.println() should |
| 8 | 1561 only be used for debugging. Therefore it is possible to highlight debugging |
| 237 | 1562 statements differently. To do this you must add the following definition in |
| 7 | 1563 your startup file: > |
| 1564 :let java_highlight_debug=1 | |
| 1565 The result will be that those statements are highlighted as 'Special' | |
| 237 | 1566 characters. If you prefer to have them highlighted differently you must define |
| 7 | 1567 new highlightings for the following groups.: |
| 1568 Debug, DebugSpecial, DebugString, DebugBoolean, DebugType | |
| 1569 which are used for the statement itself, special characters used in debug | |
| 237 | 1570 strings, strings, boolean constants and types (this, super) respectively. I |
| 7 | 1571 have opted to chose another background for those statements. |
| 1572 | |
| 1624 | 1573 In order to help you write code that can be easily ported between Java and |
| 1574 C++, all C++ keywords can be marked as an error in a Java program. To | |
| 1575 have this add this line in your .vimrc file: > | |
| 1576 :let java_allow_cpp_keywords = 0 | |
| 7 | 1577 |
| 237 | 1578 Javadoc is a program that takes special comments out of Java program files and |
| 1579 creates HTML pages. The standard configuration will highlight this HTML code | |
| 1580 similarly to HTML files (see |html.vim|). You can even add Javascript | |
| 1581 and CSS inside this code (see below). There are four differences however: | |
| 7 | 1582 1. The title (all characters up to the first '.' which is followed by |
| 1583 some white space or up to the first '@') is colored differently (to change | |
| 1584 the color change the group CommentTitle). | |
| 1585 2. The text is colored as 'Comment'. | |
| 1586 3. HTML comments are colored as 'Special' | |
| 237 | 1587 4. The special Javadoc tags (@see, @param, ...) are highlighted as specials |
| 7 | 1588 and the argument (for @see, @param, @exception) as Function. |
| 1589 To turn this feature off add the following line to your startup file: > | |
| 1590 :let java_ignore_javadoc=1 | |
| 1591 | |
| 237 | 1592 If you use the special Javadoc comment highlighting described above you |
| 1593 can also turn on special highlighting for Javascript, visual basic | |
| 1594 scripts and embedded CSS (stylesheets). This makes only sense if you | |
| 1595 actually have Javadoc comments that include either Javascript or embedded | |
| 1596 CSS. The options to use are > | |
| 7 | 1597 :let java_javascript=1 |
| 1598 :let java_css=1 | |
| 1599 :let java_vb=1 | |
| 1600 | |
| 1601 In order to highlight nested parens with different colors define colors | |
| 1602 for javaParen, javaParen1 and javaParen2, for example with > | |
| 1603 :hi link javaParen Comment | |
| 1604 or > | |
| 1605 :hi javaParen ctermfg=blue guifg=#0000ff | |
| 1606 | |
| 1607 If you notice highlighting errors while scrolling backwards, which are fixed | |
| 1608 when redrawing with CTRL-L, try setting the "java_minlines" internal variable | |
| 1609 to a larger number: > | |
| 1610 :let java_minlines = 50 | |
| 1611 This will make the syntax synchronization start 50 lines before the first | |
| 1612 displayed line. The default value is 10. The disadvantage of using a larger | |
| 1613 number is that redrawing can become slow. | |
| 1614 | |
| 1615 | |
| 501 | 1616 LACE *lace.vim* *ft-lace-syntax* |
| 7 | 1617 |
| 1618 Lace (Language for Assembly of Classes in Eiffel) is case insensitive, but the | |
| 1619 style guide lines are not. If you prefer case insensitive highlighting, just | |
| 1620 define the vim variable 'lace_case_insensitive' in your startup file: > | |
| 1621 :let lace_case_insensitive=1 | |
| 1622 | |
| 1623 | |
| 501 | 1624 LEX *lex.vim* *ft-lex-syntax* |
| 7 | 1625 |
| 1626 Lex uses brute-force synchronizing as the "^%%$" section delimiter | |
| 1627 gives no clue as to what section follows. Consequently, the value for > | |
| 1628 :syn sync minlines=300 | |
| 1629 may be changed by the user if s/he is experiencing synchronization | |
| 1630 difficulties (such as may happen with large lex files). | |

| 555 | 1640 LISP *lisp.vim* *ft-lisp-syntax* |
| 1641 | |
| 1642 The lisp syntax highlighting provides two options: > | |
| 1643 | |
| 1644 g:lisp_instring : if it exists, then "(...)" strings are highlighted | |
| 1645 as if the contents of the string were lisp. | |
| 1646 Useful for AutoLisp. | |
| 1647 g:lisp_rainbow : if it exists and is nonzero, then differing levels | |
| 1648 of parenthesization will receive different | |
| 1649 highlighting. | |
| 1650 < | |
| 1651 The g:lisp_rainbow option provides 10 levels of individual colorization for | |
| 1652 the parentheses and backquoted parentheses. Because of the quantity of | |
| 1653 colorization levels, unlike non-rainbow highlighting, the rainbow mode | |
| 1654 specifies its highlighting using ctermfg and guifg, thereby bypassing the | |
| 1655 usual colorscheme control using standard highlighting groups. The actual | |
| 1656 highlighting used depends on the dark/bright setting (see |'bg'|). | |
| 1657 | |
| 1658 | |
| 501 | 1659 LITE *lite.vim* *ft-lite-syntax* |
| 7 | 1660 |
| 1661 There are two options for the lite syntax highlighting. | |
| 1662 | |
| 1663 If you like SQL syntax highlighting inside Strings, use this: > | |
| 1664 | |
| 1665 :let lite_sql_query = 1 | |
| 1666 | |
| 1667 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 1668 set "lite_minlines" to the value you desire. Example: > | |
| 1669 | |
| 1670 :let lite_minlines = 200 | |
| 1671 | |
| 1672 | |
| 501 | 1673 LPC *lpc.vim* *ft-lpc-syntax* |
| 7 | 1674 |
| 237 | 1675 LPC stands for a simple, memory-efficient language: Lars Pensj| C. The |
| 7 | 1676 file name of LPC is usually *.c. Recognizing these files as LPC would bother |
| 1677 users writing only C programs. If you want to use LPC syntax in Vim, you | |
| 1678 should set a variable in your .vimrc file: > | |
| 1679 | |
| 1680 :let lpc_syntax_for_c = 1 | |
| 1681 | |
| 1682 If it doesn't work properly for some particular C or LPC files, use a | |
| 1683 modeline. For a LPC file: | |
| 1684 | |
| 1685 // vim:set ft=lpc: | |
| 1686 | |
| 1687 For a C file that is recognized as LPC: | |
| 1688 | |
| 1689 // vim:set ft=c: | |
| 1690 | |
| 1691 If you don't want to set the variable, use the modeline in EVERY LPC file. | |
| 1692 | |
| 1693 There are several implementations for LPC, we intend to support most widely | |
| 237 | 1694 used ones. Here the default LPC syntax is for MudOS series, for MudOS v22 |
| 7 | 1695 and before, you should turn off the sensible modifiers, and this will also |
| 1696 asserts the new efuns after v22 to be invalid, don't set this variable when | |
| 1697 you are using the latest version of MudOS: > | |
| 1698 | |
| 1699 :let lpc_pre_v22 = 1 | |
| 1700 | |
| 1701 For LpMud 3.2 series of LPC: > | |
| 1702 | |
| 1703 :let lpc_compat_32 = 1 | |
| 1704 | |
| 1705 For LPC4 series of LPC: > | |
| 1706 | |
| 1707 :let lpc_use_lpc4_syntax = 1 | |
| 1708 | |
| 1709 For uLPC series of LPC: | |
| 1710 uLPC has been developed to Pike, so you should use Pike syntax | |
| 1711 instead, and the name of your source file should be *.pike | |
| 1712 | |
| 1713 | |
| 501 | 1714 LUA *lua.vim* *ft-lua-syntax* |
| 7 | 1715 |
| 838 | 1716 This syntax file may be used for Lua 4.0, Lua 5.0 or Lua 5.1 (the latter is |
| 1717 the default). You can select one of these versions using the global variables | |
| 1718 lua_version and lua_subversion. For example, to activate Lua | |
| 1719 4.0 syntax highlighting, use this command: > | |
| 7 | 1720 |
| 1721 :let lua_version = 4 | |
| 1722 | |
| 838 | 1723 If you are using Lua 5.0, use these commands: > |
| 1724 | |
| 1725 :let lua_version = 5 | |
| 1726 :let lua_subversion = 0 | |
| 1727 | |
| 1728 To restore highlighting for Lua 5.1: > | |
| 1729 | |
| 1730 :let lua_version = 5 | |
| 1731 :let lua_subversion = 1 | |
| 7 | 1732 |
| 1733 | |
| 501 | 1734 MAIL *mail.vim* *ft-mail.vim* |
| 7 | 1735 |
| 1736 Vim highlights all the standard elements of an email (headers, signatures, | |
| 237 | 1737 quoted text and URLs / email addresses). In keeping with standard conventions, |
| 7 | 1738 signatures begin in a line containing only "--" followed optionally by |
| 1739 whitespaces and end with a newline. | |
| 1740 | |
| 1741 Vim treats lines beginning with ']', '}', '|', '>' or a word followed by '>' | |
| 237 | 1742 as quoted text. However Vim highlights headers and signatures in quoted text |
| 7 | 1743 only if the text is quoted with '>' (optionally followed by one space). |
| 1744 | |
| 1745 By default mail.vim synchronises syntax to 100 lines before the first | |
| 237 | 1746 displayed line. If you have a slow machine, and generally deal with emails |
| 7 | 1747 with short headers, you can change this to a smaller value: > |
| 1748 | |
| 1749 :let mail_minlines = 30 | |
| 1750 | |
| 1751 | |
| 501 | 1752 MAKE *make.vim* *ft-make-syntax* |
| 7 | 1753 |
| 1754 In makefiles, commands are usually highlighted to make it easy for you to spot | |

| 1763 Maple V, by Waterloo Maple Inc, supports symbolic algebra. The language | |
| 1764 supports many packages of functions which are selectively loaded by the user. | |
| 1765 The standard set of packages' functions as supplied in Maple V release 4 may be | |
| 1766 highlighted at the user's discretion. Users may place in their .vimrc file: > | |
| 1767 | |

| 501 | 1830 MSQL *msql.vim* *ft-msql-syntax* |
| 7 | 1831 |
| 1832 There are two options for the msql syntax highlighting. | |
| 1833 | |
| 1834 If you like SQL syntax highlighting inside Strings, use this: > | |
| 1835 | |
| 1836 :let msql_sql_query = 1 | |
| 1837 | |
| 1838 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 1839 set "msql_minlines" to the value you desire. Example: > | |
| 1840 | |
| 1841 :let msql_minlines = 200 | |
| 1842 | |
| 1843 | |
| 501 | 1844 NCF *ncf.vim* *ft-ncf-syntax* |
| 7 | 1845 |
| 1846 There is one option for NCF syntax highlighting. | |
| 1847 | |
| 1848 If you want to have unrecognized (by ncf.vim) statements highlighted as | |
| 1849 errors, use this: > | |
| 1850 | |
| 1851 :let ncf_highlight_unknowns = 1 | |
| 1852 | |
| 1853 If you don't want to highlight these errors, leave it unset. | |
| 1854 | |
| 1855 | |
| 501 | 1856 NROFF *nroff.vim* *ft-nroff-syntax* |
| 7 | 1857 |
| 1858 The nroff syntax file works with AT&T n/troff out of the box. You need to | |
| 1859 activate the GNU groff extra features included in the syntax file before you | |
| 1860 can use them. | |
| 1861 | |
| 1862 For example, Linux and BSD distributions use groff as their default text | |
| 237 | 1863 processing package. In order to activate the extra syntax highlighting |
| 7 | 1864 features for groff, add the following option to your start-up files: > |
| 1865 | |
| 1866 :let b:nroff_is_groff = 1 | |
| 1867 | |
| 1868 Groff is different from the old AT&T n/troff that you may still find in | |
| 1869 Solaris. Groff macro and request names can be longer than 2 characters and | |
| 1870 there are extensions to the language primitives. For example, in AT&T troff | |
| 237 | 1871 you access the year as a 2-digit number with the request \(yr. In groff you |
| 7 | 1872 can use the same request, recognized for compatibility, or you can use groff's |
| 1873 native syntax, \[yr]. Furthermore, you can use a 4-digit year directly: | |
| 1874 \[year]. Macro requests can be longer than 2 characters, for example, GNU mm | |
| 1875 accepts the requests ".VERBON" and ".VERBOFF" for creating verbatim | |
| 1876 environments. | |
| 1877 | |
| 1878 In order to obtain the best formatted output g/troff can give you, you should | |
| 1879 follow a few simple rules about spacing and punctuation. | |
| 1880 | |
| 1881 1. Do not leave empty spaces at the end of lines. | |
| 1882 | |
| 1883 2. Leave one space and one space only after an end-of-sentence period, | |
| 1884 exclamation mark, etc. | |
| 1885 | |
| 1886 3. For reasons stated below, it is best to follow all period marks with a | |
| 1887 carriage return. | |
| 1888 | |
| 1889 The reason behind these unusual tips is that g/n/troff have a line breaking | |
| 1890 algorithm that can be easily upset if you don't follow the rules given above. | |
| 1891 | |
| 1892 Unlike TeX, troff fills text line-by-line, not paragraph-by-paragraph and, | |
| 1893 furthermore, it does not have a concept of glue or stretch, all horizontal and | |
| 1894 vertical space input will be output as is. | |
| 1895 | |
| 1896 Therefore, you should be careful about not using more space between sentences | |
| 1897 than you intend to have in your final document. For this reason, the common | |
| 1898 practice is to insert a carriage return immediately after all punctuation | |
| 237 | 1899 marks. If you want to have "even" text in your final processed output, you |
| 7 | 1900 need to maintaining regular spacing in the input text. To mark both trailing |
| 1901 spaces and two or more spaces after a punctuation as an error, use: > | |
| 1902 | |
| 1903 :let nroff_space_errors = 1 | |
| 1904 | |
| 1905 Another technique to detect extra spacing and other errors that will interfere | |
| 1906 with the correct typesetting of your file, is to define an eye-catching | |
| 1907 highlighting definition for the syntax groups "nroffDefinition" and | |
| 237 | 1908 "nroffDefSpecial" in your configuration files. For example: > |
| 7 | 1909 |
| 1910 hi def nroffDefinition term=italic cterm=italic gui=reverse | |
| 1911 hi def nroffDefSpecial term=italic,bold cterm=italic,bold | |
| 1912 \ gui=reverse,bold | |
| 1913 | |
| 1914 If you want to navigate preprocessor entries in your source file as easily as | |
| 1915 with section markers, you can activate the following option in your .vimrc | |
| 1916 file: > | |
| 1917 | |
| 1918 let b:preprocs_as_sections = 1 | |
| 1919 | |
| 9 | 1920 As well, the syntax file adds an extra paragraph marker for the extended |
| 7 | 1921 paragraph macro (.XP) in the ms package. |
| 1922 | |
| 1923 Finally, there is a |groff.vim| syntax file that can be used for enabling | |
| 1924 groff syntax highlighting either on a file basis or globally by default. | |
| 1925 | |
| 1926 | |
| 501 | 1927 OCAML *ocaml.vim* *ft-ocaml-syntax* |
| 7 | 1928 |
| 1929 The OCaml syntax file handles files having the following prefixes: .ml, | |
| 1930 .mli, .mll and .mly. By setting the following variable > | |
| 1931 | |
| 1932 :let ocaml_revised = 1 | |
| 1933 | |
| 1934 you can switch from standard OCaml-syntax to revised syntax as supported | |
| 1935 by the camlp4 preprocessor. Setting the variable > | |
| 1936 | |
| 1937 :let ocaml_noend_error = 1 | |
| 1938 | |
| 1939 prevents highlighting of "end" as error, which is useful when sources | |
| 1940 contain very long structures that Vim does not synchronize anymore. | |
| 1941 | |
| 1942 | |
| 501 | 1943 PAPP *papp.vim* *ft-papp-syntax* |
| 7 | 1944 |
| 1945 The PApp syntax file handles .papp files and, to a lesser extend, .pxml | |
| 1946 and .pxsl files which are all a mixture of perl/xml/html/other using xml | |
| 237 | 1947 as the top-level file format. By default everything inside phtml or pxml |
| 1948 sections is treated as a string with embedded preprocessor commands. If | |
| 7 | 1949 you set the variable: > |
| 1950 | |
| 1951 :let papp_include_html=1 | |
| 1952 | |
| 1953 in your startup file it will try to syntax-hilight html code inside phtml | |
| 1954 sections, but this is relatively slow and much too colourful to be able to | |
| 237 | 1955 edit sensibly. ;) |
| 7 | 1956 |
| 1957 The newest version of the papp.vim syntax file can usually be found at | |
| 1958 http://papp.plan9.de. | |
| 1959 | |
| 1960 | |
| 501 | 1961 PASCAL *pascal.vim* *ft-pascal-syntax* |
| 7 | 1962 |
| 1963 Files matching "*.p" could be Progress or Pascal. If the automatic detection | |
| 1964 doesn't work for you, or you don't edit Progress at all, use this in your | |
| 1965 startup vimrc: > | |
| 1966 | |
| 1967 :let filetype_p = "pascal" | |
| 1968 | |
| 1969 The Pascal syntax file has been extended to take into account some extensions | |
| 1970 provided by Turbo Pascal, Free Pascal Compiler and GNU Pascal Compiler. | |
| 237 | 1971 Delphi keywords are also supported. By default, Turbo Pascal 7.0 features are |
| 7 | 1972 enabled. If you prefer to stick with the standard Pascal keywords, add the |
| 1973 following line to your startup file: > | |
| 1974 | |
| 1975 :let pascal_traditional=1 | |
| 1976 | |
| 1977 To switch on Delphi specific constructions (such as one-line comments, | |
| 1978 keywords, etc): > | |
| 1979 | |
| 1980 :let pascal_delphi=1 | |
| 1981 | |
| 1982 | |
| 1983 The option pascal_symbol_operator controls whether symbol operators such as +, | |
| 1984 *, .., etc. are displayed using the Operator color or not. To colorize symbol | |
| 1985 operators, add the following line to your startup file: > | |
| 1986 | |
| 1987 :let pascal_symbol_operator=1 | |
| 1988 | |
| 1989 Some functions are highlighted by default. To switch it off: > | |
| 1990 | |
| 1991 :let pascal_no_functions=1 | |

1993 Furthermore, there are specific variables for some compilers. Besides |
| 7 | 1994 pascal_delphi, there are pascal_gpc and pascal_fpc. Default extensions try to |
| 1995 match Turbo Pascal. > | |

| 501 | 2015 PERL *perl.vim* *ft-perl-syntax* |
| 7 | 2016 |
| 2017 There are a number of possible options to the perl syntax highlighting. | |
| 2018 | |
| 2019 If you use POD files or POD segments, you might: > | |
| 2020 | |
| 2021 :let perl_include_pod = 1 | |
| 2022 | |
| 22 | 2023 The reduce the complexity of parsing (and increase performance) you can switch |
| 2024 off two elements in the parsing of variable names and contents. > | |
| 2025 | |
| 2026 To handle package references in variable and function names not differently | |
| 2027 from the rest of the name (like 'PkgName::' in '$PkgName::VarName'): > | |
| 2028 | |
| 2029 :let perl_no_scope_in_variables = 1 | |
| 2030 | |
| 2031 (In Vim 6.x it was the other way around: "perl_want_scope_in_variables" | |
| 2032 enabled it.) | |
| 2033 | |
| 2034 If you do not want complex things like '@{${"foo"}}' to be parsed: > | |
| 2035 | |
| 2036 :let perl_no_extended_vars = 1 | |
| 2037 | |
| 26 | 2038 (In Vim 6.x it was the other way around: "perl_extended_vars" enabled it.) |
| 7 | 2039 |
| 237 | 2040 The coloring strings can be changed. By default strings and qq friends will be |
| 2041 highlighted like the first line. If you set the variable | |
| 7 | 2042 perl_string_as_statement, it will be highlighted as in the second line. |
| 2043 | |
| 2044 "hello world!"; qq|hello world|; | |
| 2045 ^^^^^^^^^^^^^^NN^^^^^^^^^^^^^^^N (unlet perl_string_as_statement) | |
| 2046 S^^^^^^^^^^^^SNNSSS^^^^^^^^^^^SN (let perl_string_as_statement) | |
| 2047 | |
| 2048 (^ = perlString, S = perlStatement, N = None at all) | |
| 2049 | |
| 237 | 2050 The syncing has 3 options. The first two switch off some triggering of |
| 7 | 2051 synchronization and should only be needed in case it fails to work properly. |
| 2052 If while scrolling all of a sudden the whole screen changes color completely | |
| 237 | 2053 then you should try and switch off one of those. Let me know if you can figure |
| 7 | 2054 out the line that causes the mistake. |
| 2055 | |
| 2056 One triggers on "^\s*sub\s*" and the other on "^[$@%]" more or less. > | |

| 2066 If you want to use folding with perl, set perl_fold: > | |

| 7 | 2073 |
| 632 | 2074 To avoid folding packages or subs when perl_fold is let, let the appropriate |
| 2075 variable(s): > | |

| 501 | 2082 PHP3 and PHP4 *php.vim* *php3.vim* *ft-php-syntax* *ft-php3-syntax* |
| 7 | 2083 |
| 2084 [note: previously this was called "php3", but since it now also supports php4 | |
| 2085 it has been renamed to "php"] | |
| 2086 | |
| 2087 There are the following options for the php syntax highlighting. | |
| 2088 | |
| 2089 If you like SQL syntax highlighting inside Strings: > | |
| 2090 | |

| 2133 | |
| 2134 | |
| 816 | 2135 PLAINTEX *plaintex.vim* *ft-plaintex-syntax* |
| 2136 | |
| 2137 TeX is a typesetting language, and plaintex is the file type for the "plain" | |
| 2138 variant of TeX. If you never want your *.tex files recognized as plain TeX, | |
| 856 | 2139 see |ft-tex-plugin|. |
| 816 | 2140 |
| 2141 This syntax file has the option > | |
| 2142 | |
| 2143 let g:plaintex_delimiters = 1 | |
| 2144 | |
| 2145 if you want to highlight brackets "[]" and braces "{}". | |
| 2146 | |
| 2147 | |
| 501 | 2148 PPWIZARD *ppwiz.vim* *ft-ppwiz-syntax* |
| 7 | 2149 |
| 2150 PPWizard is a preprocessor for HTML and OS/2 INF files | |
| 2151 | |
| 2152 This syntax file has the options: | |
| 2153 | |
| 2154 - ppwiz_highlight_defs : determines highlighting mode for PPWizard's | |
| 237 | 2155 definitions. Possible values are |
| 7 | 2156 |
| 2157 ppwiz_highlight_defs = 1 : PPWizard #define statements retain the | |
| 237 | 2158 colors of their contents (e.g. PPWizard macros and variables) |
| 7 | 2159 |
| 2160 ppwiz_highlight_defs = 2 : preprocessor #define and #evaluate | |
| 2161 statements are shown in a single color with the exception of line | |
| 2162 continuation symbols | |
| 2163 | |
| 2164 The default setting for ppwiz_highlight_defs is 1. | |
| 2165 | |
| 2166 - ppwiz_with_html : If the value is 1 (the default), highlight literal | |
| 2167 HTML code; if 0, treat HTML code like ordinary text. | |
| 2168 | |
| 2169 | |
| 501 | 2170 PHTML *phtml.vim* *ft-phtml-syntax* |
| 7 | 2171 |
| 2172 There are two options for the phtml syntax highlighting. | |
| 2173 | |
| 2174 If you like SQL syntax highlighting inside Strings, use this: > | |
| 2175 | |
| 2176 :let phtml_sql_query = 1 | |
| 2177 | |
| 2178 For syncing, minlines defaults to 100. If you prefer another value, you can | |
| 2179 set "phtml_minlines" to the value you desire. Example: > | |
| 2180 | |
| 2181 :let phtml_minlines = 200 | |
| 2182 | |
| 2183 | |
| 501 | 2184 POSTSCRIPT *postscr.vim* *ft-postscr-syntax* |
| 7 | 2185 |
| 2186 There are several options when it comes to highlighting PostScript. | |
| 2187 | |
| 2188 First which version of the PostScript language to highlight. There are | |
| 2189 currently three defined language versions, or levels. Level 1 is the original | |
| 2190 and base version, and includes all extensions prior to the release of level 2. | |
| 2191 Level 2 is the most common version around, and includes its own set of | |
| 2192 extensions prior to the release of level 3. Level 3 is currently the highest | |
| 2193 level supported. You select which level of the PostScript language you want | |
| 2194 highlighted by defining the postscr_level variable as follows: > | |
| 2195 | |
| 2196 :let postscr_level=2 | |
| 2197 | |
| 2198 If this variable is not defined it defaults to 2 (level 2) since this is | |
| 2199 the most prevalent version currently. | |
| 2200 | |
| 2201 Note, not all PS interpreters will support all language features for a | |
| 2202 particular language level. In particular the %!PS-Adobe-3.0 at the start of | |
| 2203 PS files does NOT mean the PostScript present is level 3 PostScript! | |
| 2204 | |
| 2205 If you are working with Display PostScript, you can include highlighting of | |
| 2206 Display PS language features by defining the postscr_display variable as | |
| 2207 follows: > | |
| 2208 | |
| 2209 :let postscr_display=1 | |
| 2210 | |
| 2211 If you are working with Ghostscript, you can include highlighting of | |
| 2212 Ghostscript specific language features by defining the variable | |
| 2213 postscr_ghostscript as follows: > | |
| 2214 | |
| 2215 :let postscr_ghostscript=1 | |
| 2216 | |
| 2217 PostScript is a large language, with many predefined elements. While it | |
| 2218 useful to have all these elements highlighted, on slower machines this can | |
| 2219 cause Vim to slow down. In an attempt to be machine friendly font names and | |
| 2220 character encodings are not highlighted by default. Unless you are working | |
| 2221 explicitly with either of these this should be ok. If you want them to be | |
| 2222 highlighted you should set one or both of the following variables: > | |
| 2223 | |
| 2224 :let postscr_fonts=1 | |
| 2225 :let postscr_encodings=1 | |
| 2226 | |
| 2227 There is a stylistic option to the highlighting of and, or, and not. In | |
| 2228 PostScript the function of these operators depends on the types of their | |
| 2229 operands - if the operands are booleans then they are the logical operators, | |
| 2230 if they are integers then they are binary operators. As binary and logical | |
| 2231 operators can be highlighted differently they have to be highlighted one way | |
| 2232 or the other. By default they are treated as logical operators. They can be | |
| 2233 highlighted as binary operators by defining the variable | |
| 2234 postscr_andornot_binary as follows: > | |
| 2235 | |
| 2236 :let postscr_andornot_binary=1 | |
| 2237 < | |
| 2238 | |
| 501 | 2239 *ptcap.vim* *ft-printcap-syntax* |
| 2240 PRINTCAP + TERMCAP *ft-ptcap-syntax* *ft-termcap-syntax* | |
| 7 | 2241 |
| 2242 This syntax file applies to the printcap and termcap databases. | |
| 2243 | |
| 2244 In order for Vim to recognize printcap/termcap files that do not match | |
| 2245 the patterns *printcap*, or *termcap*, you must put additional patterns | |
| 2246 appropriate to your system in your |myfiletypefile| file. For these | |
| 2247 patterns, you must set the variable "b:ptcap_type" to either "print" or | |
| 2248 "term", and then the 'filetype' option to ptcap. | |
| 2249 | |
| 2250 For example, to make Vim identify all files in /etc/termcaps/ as termcap | |
| 2251 files, add the following: > | |
| 2252 | |
| 2253 :au BufNewFile,BufRead /etc/termcaps/* let b:ptcap_type = "term" | | |
| 2254 \ set filetype=ptcap | |
| 2255 | |
| 2256 If you notice highlighting errors while scrolling backwards, which | |
| 2257 are fixed when redrawing with CTRL-L, try setting the "ptcap_minlines" | |
| 2258 internal variable to a larger number: > | |
| 2259 | |
| 2260 :let ptcap_minlines = 50 | |
| 2261 | |
| 2262 (The default is 20 lines.) | |
| 2263 | |
| 2264 | |
| 501 | 2265 PROGRESS *progress.vim* *ft-progress-syntax* |
| 7 | 2266 |
| 2267 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
| 2268 doesn't work for you, or you don't edit cweb at all, use this in your | |
| 2269 startup vimrc: > | |
| 2270 :let filetype_w = "progress" | |
| 2271 The same happens for "*.i", which could be assembly, and "*.p", which could be | |
| 2272 Pascal. Use this if you don't use assembly and Pascal: > | |
| 2273 :let filetype_i = "progress" | |
| 2274 :let filetype_p = "progress" | |
| 2275 | |
| 2276 | |
| 501 | 2277 PYTHON *python.vim* *ft-python-syntax* |
| 7 | 2278 |
| 2279 There are four options to control Python syntax highlighting. | |
| 2280 | |
| 2281 For highlighted numbers: > | |
| 2282 :let python_highlight_numbers = 1 | |
| 2283 | |
| 2284 For highlighted builtin functions: > | |
| 2285 :let python_highlight_builtins = 1 | |
| 2286 | |
| 2287 For highlighted standard exceptions: > | |
| 2288 :let python_highlight_exceptions = 1 | |
| 2289 | |
| 2596 | 2290 For highlighted trailing whitespace and mix of spaces and tabs: > |
| 7 | 2291 :let python_highlight_space_errors = 1 |
| 2292 | |
| 2293 If you want all possible Python highlighting (the same as setting the | |
| 2294 preceding three options): > | |
| 2295 :let python_highlight_all = 1 | |
| 2296 | |
| 2297 | |
| 501 | 2298 QUAKE *quake.vim* *ft-quake-syntax* |
| 7 | 2299 |
| 2300 The Quake syntax definition should work for most any FPS (First Person | |
| 237 | 2301 Shooter) based on one of the Quake engines. However, the command names vary |
| 7 | 2302 a bit between the three games (Quake, Quake 2, and Quake 3 Arena) so the |
| 2303 syntax definition checks for the existence of three global variables to allow | |
| 237 | 2304 users to specify what commands are legal in their files. The three variables |
| 7 | 2305 can be set for the following effects: |
| 2306 | |
| 2307 set to highlight commands only available in Quake: > | |
| 2308 :let quake_is_quake1 = 1 | |
| 2309 | |
| 2310 set to highlight commands only available in Quake 2: > | |
| 2311 :let quake_is_quake2 = 1 | |
| 2312 | |
| 2313 set to highlight commands only available in Quake 3 Arena: > | |
| 2314 :let quake_is_quake3 = 1 | |
| 2315 | |
| 2316 Any combination of these three variables is legal, but might highlight more | |
| 2317 commands than are actually available to you by the game. | |
| 2318 | |
| 2319 | |
| 501 | 2320 READLINE *readline.vim* *ft-readline-syntax* |
| 7 | 2321 |
| 2322 The readline library is primarily used by the BASH shell, which adds quite a | |
| 237 | 2323 few commands and options to the ones already available. To highlight these |
| 7 | 2324 items as well you can add the following to your |vimrc| or just type it in the |
| 2325 command line before loading a file with the readline syntax: > | |
| 2326 let readline_has_bash = 1 | |
| 2327 | |
| 2328 This will add highlighting for the commands that BASH (version 2.05a and | |
| 2329 later, and part earlier) adds. | |
| 2330 | |
| 2331 | |
| 501 | 2332 REXX *rexx.vim* *ft-rexx-syntax* |
| 7 | 2333 |
| 2334 If you notice highlighting errors while scrolling backwards, which are fixed | |
| 2335 when redrawing with CTRL-L, try setting the "rexx_minlines" internal variable | |
| 2336 to a larger number: > | |
| 2337 :let rexx_minlines = 50 | |
| 2338 This will make the syntax synchronization start 50 lines before the first | |
| 2339 displayed line. The default value is 10. The disadvantage of using a larger | |
| 2340 number is that redrawing can become slow. | |
| 2341 | |
| 2342 | |
| 501 | 2343 RUBY *ruby.vim* *ft-ruby-syntax* |
| 7 | 2344 |
| 572 | 2345 There are a number of options to the Ruby syntax highlighting. |
| 7 | 2346 |
| 2347 By default, the "end" keyword is colorized according to the opening statement | |
| 572 | 2348 of the block it closes. While useful, this feature can be expensive; if you |
| 7 | 2349 experience slow redrawing (or you are on a terminal with poor color support) |
| 2350 you may want to turn it off by defining the "ruby_no_expensive" variable: > | |
| 572 | 2351 |
| 7 | 2352 :let ruby_no_expensive = 1 |
| 1224 | 2353 < |
| 7 | 2354 In this case the same color will be used for all control keywords. |
| 2355 | |
| 2356 If you do want this feature enabled, but notice highlighting errors while | |
| 2357 scrolling backwards, which are fixed when redrawing with CTRL-L, try setting | |
| 2358 the "ruby_minlines" variable to a value larger than 50: > | |
| 572 | 2359 |
| 7 | 2360 :let ruby_minlines = 100 |
| 1224 | 2361 < |
| 7 | 2362 Ideally, this value should be a number of lines large enough to embrace your |
| 2363 largest class or module. | |
| 2364 | |
| 1224 | 2365 Highlighting of special identifiers can be disabled by removing the |
| 2366 rubyIdentifier highlighting: > | |
| 2367 | |
| 2368 :hi link rubyIdentifier NONE | |
| 2369 < | |
| 7 | 2370 This will prevent highlighting of special identifiers like "ConstantName", |
| 572 | 2371 "$global_var", "@@class_var", "@instance_var", "| block_param |", and |
| 2372 ":symbol". | |
| 2373 | |
| 2374 Significant methods of Kernel, Module and Object are highlighted by default. | |
| 2375 This can be disabled by defining "ruby_no_special_methods": > | |
| 2376 | |
| 2377 :let ruby_no_special_methods = 1 | |
| 1224 | 2378 < |
| 572 | 2379 This will prevent highlighting of important methods such as "require", "attr", |
| 2380 "private", "raise" and "proc". | |
| 2381 | |
| 1224 | 2382 Ruby operators can be highlighted. This is enabled by defining |
| 2383 "ruby_operators": > | |
| 2384 | |
| 2385 :let ruby_operators = 1 | |
| 2386 < | |
| 572 | 2387 Whitespace errors can be highlighted by defining "ruby_space_errors": > |
| 2388 | |
| 2389 :let ruby_space_errors = 1 | |
| 1224 | 2390 < |
| 572 | 2391 This will highlight trailing whitespace and tabs preceded by a space character |
| 2392 as errors. This can be refined by defining "ruby_no_trail_space_error" and | |
| 2393 "ruby_no_tab_space_error" which will ignore trailing whitespace and tabs after | |
| 2394 spaces respectively. | |
| 2395 | |
| 2396 Folding can be enabled by defining "ruby_fold": > | |
| 2397 | |
| 2398 :let ruby_fold = 1 | |
| 1224 | 2399 < |
| 572 | 2400 This will set the 'foldmethod' option to "syntax" and allow folding of |
| 2401 classes, modules, methods, code blocks, heredocs and comments. | |
| 1125 | 2402 |
| 1224 | 2403 Folding of multiline comments can be disabled by defining |
| 2404 "ruby_no_comment_fold": > | |
| 2405 | |
| 2406 :let ruby_no_comment_fold = 1 | |
| 2407 < | |
| 1125 | 2408 |
| 501 | 2409 SCHEME *scheme.vim* *ft-scheme-syntax* |
| 17 | 2410 |
| 2411 By default only R5RS keywords are highlighted and properly indented. | |
| 2412 | |
| 2413 MzScheme-specific stuff will be used if b:is_mzscheme or g:is_mzscheme | |
| 2414 variables are defined. | |
| 856 | 2415 |
| 36 | 2416 Also scheme.vim supports keywords of the Chicken Scheme->C compiler. Define |
| 2417 b:is_chicken or g:is_chicken, if you need them. | |
| 17 | 2418 |
| 2419 | |
| 501 | 2420 SDL *sdl.vim* *ft-sdl-syntax* |
| 7 | 2421 |
| 2422 The SDL highlighting probably misses a few keywords, but SDL has so many | |
| 2423 of them it's almost impossibly to cope. | |
| 2424 | |
| 2425 The new standard, SDL-2000, specifies that all identifiers are | |
| 2426 case-sensitive (which was not so before), and that all keywords can be | |
| 237 | 2427 used either completely lowercase or completely uppercase. To have the |
| 7 | 2428 highlighting reflect this, you can set the following variable: > |
| 2429 :let sdl_2000=1 | |
| 2430 | |
| 237 | 2431 This also sets many new keywords. If you want to disable the old |
| 7 | 2432 keywords, which is probably a good idea, use: > |
| 2433 :let SDL_no_96=1 | |
| 2434 | |
| 2435 | |
| 2436 The indentation is probably also incomplete, but right now I am very | |
| 2437 satisfied with it for my own projects. | |
| 2438 | |
| 2439 | |
| 501 | 2440 SED *sed.vim* *ft-sed-syntax* |
| 7 | 2441 |
| 2442 To make tabs stand out from regular blanks (accomplished by using Todo | |
| 2443 highlighting on the tabs), define "highlight_sedtabs" by putting > | |
| 2444 | |
| 2445 :let highlight_sedtabs = 1 | |
| 2446 | |
| 2447 in the vimrc file. (This special highlighting only applies for tabs | |
| 2448 inside search patterns, replacement texts, addresses or text included | |
| 2449 by an Append/Change/Insert command.) If you enable this option, it is | |
| 2450 also a good idea to set the tab width to one character; by doing that, | |
| 2451 you can easily count the number of tabs in a string. | |
| 2452 | |
| 2453 Bugs: | |
| 2454 | |
| 2455 The transform command (y) is treated exactly like the substitute | |
| 2456 command. This means that, as far as this syntax file is concerned, | |
| 2457 transform accepts the same flags as substitute, which is wrong. | |
| 2458 (Transform accepts no flags.) I tolerate this bug because the | |
| 2459 involved commands need very complex treatment (95 patterns, one for | |
| 2460 each plausible pattern delimiter). | |
| 2461 | |
| 2462 | |
| 501 | 2463 SGML *sgml.vim* *ft-sgml-syntax* |
| 7 | 2464 |
| 2465 The coloring scheme for tags in the SGML file works as follows. | |
| 2466 | |
| 2467 The <> of opening tags are colored differently than the </> of a closing tag. | |
| 2468 This is on purpose! For opening tags the 'Function' color is used, while for | |
| 2469 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
| 2470 defined for you) | |
| 2471 | |
| 2472 Known tag names are colored the same way as statements in C. Unknown tag | |
| 2473 names are not colored which makes it easy to spot errors. | |
| 2474 | |
| 237 | 2475 Note that the same is true for argument (or attribute) names. Known attribute |
| 7 | 2476 names are colored differently than unknown ones. |
| 2477 | |
| 237 | 2478 Some SGML tags are used to change the rendering of text. The following tags |
| 7 | 2479 are recognized by the sgml.vim syntax coloring file and change the way normal |
| 2480 text is shown: <varname> <emphasis> <command> <function> <literal> | |
| 2481 <replaceable> <ulink> and <link>. | |
| 2482 | |
| 2483 If you want to change how such text is rendered, you must redefine the | |
| 2484 following syntax groups: | |
| 2485 | |
| 2486 - sgmlBold | |
| 2487 - sgmlBoldItalic | |
| 2488 - sgmlUnderline | |
| 2489 - sgmlItalic | |
| 2490 - sgmlLink for links | |
| 2491 | |
| 2492 To make this redefinition work you must redefine them all and define the | |
| 2493 following variable in your vimrc (this is due to the order in which the files | |
| 2494 are read during initialization) > | |
| 2495 let sgml_my_rendering=1 | |
| 2496 | |
| 2497 You can also disable this rendering by adding the following line to your | |
| 2498 vimrc file: > | |
| 2499 let sgml_no_rendering=1 | |
| 2500 | |
| 2501 (Adapted from the html.vim help text by Claudio Fleiner <claudio@fleiner.com>) | |
| 2502 | |
| 2503 | |
| 501 | 2504 SH *sh.vim* *ft-sh-syntax* *ft-bash-syntax* *ft-ksh-syntax* |
| 7 | 2505 |
| 1624 | 2506 This covers the "normal" Unix (Bourne) sh, bash and the Korn shell. |
| 7 | 2507 |
| 2508 Vim attempts to determine which shell type is in use by specifying that | |
| 2509 various filenames are of specific types: > | |
| 2510 | |
| 2511 ksh : .kshrc* *.ksh | |
| 2512 bash: .bashrc* bashrc bash.bashrc .bash_profile* *.bash | |
| 2513 < | |
| 2514 If none of these cases pertain, then the first line of the file is examined | |
| 2515 (ex. /bin/sh /bin/ksh /bin/bash). If the first line specifies a shelltype, | |
| 2516 then that shelltype is used. However some files (ex. .profile) are known to | |
| 2517 be shell files but the type is not apparent. Furthermore, on many systems | |
| 828 | 2518 sh is symbolically linked to "bash" (Linux, Windows+cygwin) or "ksh" (Posix). |
| 7 | 2519 |
| 2520 One may specify a global default by instantiating one of the following three | |
| 2521 variables in your <.vimrc>: | |
| 2522 | |
| 2523 ksh: > | |
| 828 | 2524 let g:is_kornshell = 1 |
| 2525 < posix: (using this is the same as setting is_kornshell to 1) > | |
| 2526 let g:is_posix = 1 | |
| 7 | 2527 < bash: > |
| 828 | 2528 let g:is_bash = 1 |
| 1624 | 2529 < sh: (default) Bourne shell > |
| 828 | 2530 let g:is_sh = 1 |
| 7 | 2531 |
| 819 | 2532 If there's no "#! ..." line, and the user hasn't availed himself/herself of a |
| 2533 default sh.vim syntax setting as just shown, then syntax/sh.vim will assume | |
| 1624 | 2534 the Bourne shell syntax. No need to quote RFCs or market penetration |
| 2535 statistics in error reports, please -- just select the default version of the | |
| 2536 sh your system uses in your <.vimrc>. | |
| 2537 | |
| 2538 The syntax/sh.vim file provides several levels of syntax-based folding: > | |
| 2539 | |
| 2540 let g:sh_fold_enabled= 0 (default, no syntax folding) | |
| 2541 let g:sh_fold_enabled= 1 (enable function folding) | |
| 2542 let g:sh_fold_enabled= 2 (enable heredoc folding) | |
| 2543 let g:sh_fold_enabled= 4 (enable if/do/for folding) | |
| 7 | 2544 > |
| 2545 then various syntax items (HereDocuments and function bodies) become | |
| 1624 | 2546 syntax-foldable (see |:syn-fold|). You also may add these together |
| 2547 to get multiple types of folding: > | |
| 2548 | |
| 2549 let g:sh_fold_enabled= 3 (enables function and heredoc folding) | |
| 2550 | |
| 2551 If you notice highlighting errors while scrolling backwards which are fixed | |
| 2552 when one redraws with CTRL-L, try setting the "sh_minlines" internal variable | |
| 7 | 2553 to a larger number. Example: > |
| 2554 | |
| 2555 let sh_minlines = 500 | |
| 2556 | |
| 2557 This will make syntax synchronization start 500 lines before the first | |
| 2558 displayed line. The default value is 200. The disadvantage of using a larger | |
| 2559 number is that redrawing can become slow. | |
| 2560 | |
| 2561 If you don't have much to synchronize on, displaying can be very slow. To | |
| 2562 reduce this, the "sh_maxlines" internal variable can be set. Example: > | |
| 2563 | |
| 2564 let sh_maxlines = 100 | |
| 2565 < | |
| 2566 The default is to use the twice sh_minlines. Set it to a smaller number to | |
| 2567 speed up displaying. The disadvantage is that highlight errors may appear. | |
| 2568 | |
| 2569 | |
| 501 | 2570 SPEEDUP (AspenTech plant simulator) *spup.vim* *ft-spup-syntax* |
| 7 | 2571 |
| 2572 The Speedup syntax file has some options: | |
| 2573 | |
| 2574 - strict_subsections : If this variable is defined, only keywords for | |
| 2575 sections and subsections will be highlighted as statements but not | |
| 2576 other keywords (like WITHIN in the OPERATION section). | |
| 2577 | |
| 2578 - highlight_types : Definition of this variable causes stream types | |
| 2579 like temperature or pressure to be highlighted as Type, not as a | |
| 237 | 2580 plain Identifier. Included are the types that are usually found in |
| 7 | 2581 the DECLARE section; if you defined own types, you have to include |
| 2582 them in the syntax file. | |
| 2583 | |
| 2584 - oneline_comments : this value ranges from 1 to 3 and determines the | |
| 2585 highlighting of # style comments. | |
| 2586 | |
| 2587 oneline_comments = 1 : allow normal Speedup code after an even | |
| 2588 number of #s. | |
| 2589 | |
| 2590 oneline_comments = 2 : show code starting with the second # as | |
| 237 | 2591 error. This is the default setting. |
| 7 | 2592 |
| 2593 oneline_comments = 3 : show the whole line as error if it contains | |
| 2594 more than one #. | |
| 2595 | |
| 2596 Since especially OPERATION sections tend to become very large due to | |
| 237 | 2597 PRESETting variables, syncing may be critical. If your computer is |
| 7 | 2598 fast enough, you can increase minlines and/or maxlines near the end of |
| 2599 the syntax file. | |
| 2600 | |
| 2601 | |
| 501 | 2602 SQL *sql.vim* *ft-sql-syntax* |
| 2603 *sqlinformix.vim* *ft-sqlinformix-syntax* | |
| 720 | 2604 *sqlanywhere.vim* *ft-sqlanywhere-syntax* |
| 2605 | |
| 2606 While there is an ANSI standard for SQL, most database engines add their own | |
| 2607 custom extensions. Vim currently supports the Oracle and Informix dialects of | |
| 2608 SQL. Vim assumes "*.sql" files are Oracle SQL by default. | |
| 2609 | |
| 2610 Vim currently has SQL support for a variety of different vendors via syntax | |
| 2611 scripts. You can change Vim's default from Oracle to any of the current SQL | |
| 2612 supported types. You can also easily alter the SQL dialect being used on a | |

| 2676 terminate properly, zones delineated by $..$ and $$..$$ cannot be synchronized | |
| 2677 as there's no difference between start and end patterns. Consequently, a | |
| 7 | 2678 special "TeX comment" has been provided > |

| 2717 code shows you an example as to how you might do so: > | |
| 477 | 2718 call TexNewMathZone(sfx,mathzone,starform) |
| 2719 You'll want to provide the new math group with a unique suffix | |
| 2720 (currently, A-L and V-Z are taken by <syntax/tex.vim> itself). | |
| 2721 As an example, consider how eqnarray is set up by <syntax/tex.vim>: > | |
| 2722 call TexNewMathZone("D","eqnarray",1) | |
| 2723 You'll need to change "mathzone" to the name of your new math group, | |
| 2724 and then to the call to it in .vim/after/syntax/tex.vim. | |
| 2725 The "starform" variable, if true, implies that your new math group | |

| 2731 One may use "\makeatletter" in *.tex files, thereby making the use of "@" in | |
| 2732 commands available. However, since the *.tex file doesn't have one of the | |
| 2733 following suffices: sty cls clo dtx ltx, the syntax highlighting will flag | |

2743 Tex: Taking Advantage of Conceal Mode~ |
| 2417 | 2744 |
| 2426 | 2745 If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a |
| 2746 number of character sequences can be translated into appropriate utf-8 glyphs, | |
| 2747 including various accented characters, Greek characters in MathZones, and | |
| 2748 superscripts and subscripts in MathZones. Not all characters can be made into | |
| 2749 superscripts or subscripts; the constraint is due to what utf-8 supports. | |
| 2750 In fact, only a few characters are supported as subscripts. | |
| 2751 | |
| 2752 One way to use this is to have vertically split windows (see |CTRL-W_v|); one | |
| 2753 with |'conceallevel'| at 0 and the other at 2; and both using |'scrollbind'|. | |

2784 There is a trade-off between more accurate syntax highlighting versus screen |
| 1624 | 2785 updating speed. To improve accuracy, you may wish to increase the |
| 2786 g:vimsyn_minlines variable. The g:vimsyn_maxlines variable may be used to | |
| 2787 improve screen updating rates (see |:syn-sync| for more on this). > | |

| 2793 these two options) | |
| 2794 | |
| 2795 *g:vimsyn_embed* | |
| 2796 The g:vimsyn_embed option allows users to select what, if any, types of | |
| 2797 embedded script highlighting they wish to have. > | |
| 2798 | |
| 2799 g:vimsyn_embed == 0 : don't embed any scripts | |

| 2802 g:vimsyn_embed =~ 'P' : embed python (but only if vim supports it) | |
| 2803 g:vimsyn_embed =~ 'r' : embed ruby (but only if vim supports it) | |
| 2804 g:vimsyn_embed =~ 't' : embed tcl (but only if vim supports it) | |
| 2805 < | |
| 2806 By default, g:vimsyn_embed is "mpPr"; ie. syntax/vim.vim will support | |
| 2807 highlighting mzscheme, perl, python, and ruby by default. Vim's has("tcl") | |
| 2808 test appears to hang vim when tcl is not truly available. Thus, by default, | |
| 2809 tcl is not supported for embedding (but those of you who like tcl embedded in | |
| 2810 their vim syntax highlighting can simply include it in the g:vimembedscript | |
| 2811 option). | |
| 2812 *g:vimsyn_folding* | |
| 2813 | |
| 2814 Some folding is now supported with syntax/vim.vim: > | |

| 2817 g:vimsyn_folding =~ 'a' : augroups | |

| 2823 g:vimsyn_folding =~ 't' : fold tcl script | |
| 2824 | |
| 2825 *g:vimsyn_noerror* | |
| 846 | 2826 Not all error highlighting that syntax/vim.vim does may be correct; VimL is a |
| 2827 difficult language to highlight correctly. A way to suppress error | |
| 1624 | 2828 highlighting is to put the following line in your |vimrc|: > |
| 2829 | |
| 2830 let g:vimsyn_noerror = 1 | |

| 501 | 2834 XF86CONFIG *xf86conf.vim* *ft-xf86conf-syntax* |
| 7 | 2835 |
| 2836 The syntax of XF86Config file differs in XFree86 v3.x and v4.x. Both | |
| 2837 variants are supported. Automatic detection is used, but is far from perfect. | |
| 2838 You may need to specify the version manually. Set the variable | |
| 2839 xf86conf_xfree86_version to 3 or 4 according to your XFree86 version in | |
| 2840 your .vimrc. Example: > | |
| 2841 :let xf86conf_xfree86_version=3 | |
| 2842 When using a mix of versions, set the b:xf86conf_xfree86_version variable. | |
| 2843 | |
| 2844 Note that spaces and underscores in option names are not supported. Use | |
| 2845 "SyncOnGreen" instead of "__s yn con gr_e_e_n" if you want the option name | |
| 2846 highlighted. | |
| 2847 | |
| 2848 | |
| 501 | 2849 XML *xml.vim* *ft-xml-syntax* |
| 7 | 2850 |
| 237 | 2851 Xml namespaces are highlighted by default. This can be inhibited by |
| 7 | 2852 setting a global variable: > |
| 2853 | |
| 2854 :let g:xml_namespace_transparent=1 | |
| 2855 < | |
| 2856 *xml-folding* | |
| 2857 The xml syntax file provides syntax |folding| (see |:syn-fold|) between | |
| 237 | 2858 start and end tags. This can be turned on by > |
| 7 | 2859 |
| 2860 :let g:xml_syntax_folding = 1 | |
| 2861 :set foldmethod=syntax | |
| 2862 | |
| 2863 Note: syntax folding might slow down syntax highlighting significantly, | |
| 2864 especially for large files. | |
| 2865 | |
| 2866 | |
| 501 | 2867 X Pixmaps (XPM) *xpm.vim* *ft-xpm-syntax* |
| 7 | 2868 |
| 2869 xpm.vim creates its syntax items dynamically based upon the contents of the | |
| 2870 XPM file. Thus if you make changes e.g. in the color specification strings, | |
| 2871 you have to source it again e.g. with ":set syn=xpm". | |
| 2872 | |
| 2873 To copy a pixel with one of the colors, yank a "pixel" with "yl" and insert it | |
| 2874 somewhere else with "P". | |
| 2875 | |
| 2876 Do you want to draw with the mouse? Try the following: > | |
| 2877 :function! GetPixel() | |
| 823 | 2878 : let c = getline(".")[col(".") - 1] |
| 7 | 2879 : echo c |
| 2880 : exe "noremap <LeftMouse> <LeftMouse>r".c | |
| 2881 : exe "noremap <LeftDrag> <LeftMouse>r".c | |
| 2882 :endfunction | |

| 2891 | |
| 2892 ============================================================================== | |
| 2893 5. Defining a syntax *:syn-define* *E410* | |
| 2894 | |
| 2895 Vim understands three types of syntax items: | |
| 2896 | |
| 419 | 2897 1. Keyword |
| 7 | 2898 It can only contain keyword characters, according to the 'iskeyword' |
| 2899 option. It cannot contain other syntax items. It will only match with a | |
| 2900 complete word (there are no keyword characters before or after the match). | |
| 2901 The keyword "if" would match in "if(a=b)", but not in "ifdef x", because | |
| 2902 "(" is not a keyword character and "d" is. | |
| 2903 | |
| 419 | 2904 2. Match |
| 7 | 2905 This is a match with a single regexp pattern. |
| 2906 | |
| 419 | 2907 3. Region |
| 7 | 2908 This starts at a match of the "start" regexp pattern and ends with a match |
| 2909 with the "end" regexp pattern. Any other text can appear in between. A | |
| 2910 "skip" regexp pattern can be used to avoid matching the "end" pattern. | |
| 2911 | |
| 2912 Several syntax ITEMs can be put into one syntax GROUP. For a syntax group | |
| 2913 you can give highlighting attributes. For example, you could have an item | |
| 2914 to define a "/* .. */" comment and another one that defines a "// .." comment, | |
| 2915 and put them both in the "Comment" group. You can then specify that a | |
| 2916 "Comment" will be in bold font and have a blue color. You are free to make | |
| 2917 one highlight group for one syntax item, or put all items into one group. | |
| 2918 This depends on how you want to specify your highlighting attributes. Putting | |
| 2919 each item in its own group results in having to specify the highlighting | |
| 2920 for a lot of groups. | |
| 2921 | |
| 2922 Note that a syntax group and a highlight group are similar. For a highlight | |
| 2923 group you will have given highlight attributes. These attributes will be used | |
| 2924 for the syntax group with the same name. | |
| 2925 | |
| 2926 In case more than one item matches at the same position, the one that was | |
| 2927 defined LAST wins. Thus you can override previously defined syntax items by | |
| 2928 using an item that matches the same text. But a keyword always goes before a | |
| 2929 match or region. And a keyword with matching case always goes before a | |
| 2930 keyword with ignoring case. | |
| 2931 | |
| 2932 | |
| 2933 PRIORITY *:syn-priority* | |
| 2934 | |
| 2935 When several syntax items may match, these rules are used: | |
| 2936 | |
| 2937 1. When multiple Match or Region items start in the same position, the item | |
| 2938 defined last has priority. | |
| 2939 2. A Keyword has priority over Match and Region items. | |
| 2940 3. An item that starts in an earlier position has priority over items that | |
| 2941 start in later positions. | |
| 2942 | |
| 2943 | |
| 2944 DEFINING CASE *:syn-case* *E390* | |
| 2945 | |
| 419 | 2946 :sy[ntax] case [match | ignore] |
| 7 | 2947 This defines if the following ":syntax" commands will work with |
| 2948 matching case, when using "match", or with ignoring case, when using | |
| 2949 "ignore". Note that any items before this are not affected, and all | |
| 2950 items until the next ":syntax case" command are affected. | |
| 2951 | |
| 2952 | |
| 419 | 2953 SPELL CHECKING *:syn-spell* |
| 2954 | |
| 2955 :sy[ntax] spell [toplevel | notoplevel | default] | |
| 2956 This defines where spell checking is to be done for text that is not | |
| 2957 in a syntax item: | |
| 2958 | |
| 2959 toplevel: Text is spell checked. | |
| 2960 notoplevel: Text is not spell checked. | |
| 2961 default: When there is a @Spell cluster no spell checking. | |
| 2962 | |
| 2963 For text in syntax items use the @Spell and @NoSpell clusters | |
| 2964 |spell-syntax|. When there is no @Spell and no @NoSpell cluster then | |
| 2965 spell checking is done for "default" and "toplevel". | |
| 2966 | |
| 2967 To activate spell checking the 'spell' option must be set. | |
| 2968 | |
| 2969 | |
| 7 | 2970 DEFINING KEYWORDS *:syn-keyword* |
| 2971 | |
| 2972 :sy[ntax] keyword {group-name} [{options}] {keyword} .. [{options}] | |
| 2973 | |
| 2974 This defines a number of keywords. | |
| 2975 | |
| 2976 {group-name} Is a syntax group name such as "Comment". | |
| 2977 [{options}] See |:syn-arguments| below. | |
| 2978 {keyword} .. Is a list of keywords which are part of this group. | |
| 2979 | |
| 2980 Example: > | |
| 2981 :syntax keyword Type int long char | |
| 2982 < | |
| 2983 The {options} can be given anywhere in the line. They will apply to | |
| 2984 all keywords given, also for options that come after a keyword. | |
| 2985 These examples do exactly the same: > | |
| 2986 :syntax keyword Type contained int long char | |
| 2987 :syntax keyword Type int long contained char | |
| 2988 :syntax keyword Type int long char contained | |
| 838 | 2989 < *E789* |
| 7 | 2990 When you have a keyword with an optional tail, like Ex commands in |
| 2991 Vim, you can put the optional characters inside [], to define all the | |
| 2992 variations at once: > | |
| 2993 :syntax keyword vimCommand ab[breviate] n[ext] | |
| 2994 < | |
| 2995 Don't forget that a keyword can only be recognized if all the | |
| 2996 characters are included in the 'iskeyword' option. If one character | |
| 2997 isn't, the keyword will never be recognized. | |
| 2998 Multi-byte characters can also be used. These do not have to be in | |
| 2999 'iskeyword'. | |
| 3000 | |
| 3001 A keyword always has higher priority than a match or region, the | |
| 3002 keyword is used if more than one item matches. Keywords do not nest | |
| 3003 and a keyword can't contain anything else. | |
| 3004 | |
| 3005 Note that when you have a keyword that is the same as an option (even | |
| 3006 one that isn't allowed here), you can not use it. Use a match | |
| 3007 instead. | |
| 3008 | |
| 3009 The maximum length of a keyword is 80 characters. | |
| 3010 | |
| 3011 The same keyword can be defined multiple times, when its containment | |
| 3012 differs. For example, you can define the keyword once not contained | |
| 3013 and use one highlight group, and once contained, and use a different | |
| 237 | 3014 highlight group. Example: > |
| 7 | 3015 :syn keyword vimCommand tag |
| 3016 :syn keyword vimSetting contained tag | |
| 3017 < When finding "tag" outside of any syntax item, the "vimCommand" | |
| 3018 highlight group is used. When finding "tag" in a syntax item that | |
| 3019 contains "vimSetting", the "vimSetting" group is used. | |
| 3020 | |
| 3021 | |
| 3022 DEFINING MATCHES *:syn-match* | |
| 3023 | |
| 3024 :sy[ntax] match {group-name} [{options}] [excludenl] {pattern} [{options}] | |
| 3025 | |
| 3026 This defines one match. | |
| 3027 | |
| 3028 {group-name} A syntax group name such as "Comment". | |
| 3029 [{options}] See |:syn-arguments| below. | |
| 3030 [excludenl] Don't make a pattern with the end-of-line "$" | |
| 3031 extend a containing match or region. Must be | |
| 3032 given before the pattern. |:syn-excludenl| | |
| 3033 {pattern} The search pattern that defines the match. | |
| 3034 See |:syn-pattern| below. | |
| 3035 Note that the pattern may match more than one | |
| 3036 line, which makes the match depend on where | |
| 3037 Vim starts searching for the pattern. You | |
| 3038 need to make sure syncing takes care of this. | |
| 3039 | |
| 3040 Example (match a character constant): > | |
| 3041 :syntax match Character /'.'/hs=s+1,he=e-1 | |
| 3042 < | |
| 3043 | |
| 3044 DEFINING REGIONS *:syn-region* *:syn-start* *:syn-skip* *:syn-end* | |
| 3045 *E398* *E399* | |
| 3046 :sy[ntax] region {group-name} [{options}] | |
| 3047 [matchgroup={group-name}] | |
| 3048 [keepend] | |
| 3049 [extend] | |
| 3050 [excludenl] | |
| 3051 start={start_pattern} .. | |
| 3052 [skip={skip_pattern}] | |
| 3053 end={end_pattern} .. | |
| 3054 [{options}] | |
| 3055 | |
| 3056 This defines one region. It may span several lines. | |
| 3057 | |
| 3058 {group-name} A syntax group name such as "Comment". | |
| 3059 [{options}] See |:syn-arguments| below. | |
| 3060 [matchgroup={group-name}] The syntax group to use for the following | |
| 3061 start or end pattern matches only. Not used | |
| 3062 for the text in between the matched start and | |
| 3063 end patterns. Use NONE to reset to not using | |
| 3064 a different group for the start or end match. | |
| 3065 See |:syn-matchgroup|. | |
| 3066 keepend Don't allow contained matches to go past a | |
| 3067 match with the end pattern. See | |
| 3068 |:syn-keepend|. | |
| 3069 extend Override a "keepend" for an item this region | |
| 237 | 3070 is contained in. See |:syn-extend|. |
| 7 | 3071 excludenl Don't make a pattern with the end-of-line "$" |
| 3072 extend a containing match or item. Only | |
| 3073 useful for end patterns. Must be given before | |
| 3074 the patterns it applies to. |:syn-excludenl| | |
| 3075 start={start_pattern} The search pattern that defines the start of | |
| 3076 the region. See |:syn-pattern| below. | |
| 3077 skip={skip_pattern} The search pattern that defines text inside | |
| 3078 the region where not to look for the end | |
| 3079 pattern. See |:syn-pattern| below. | |
| 3080 end={end_pattern} The search pattern that defines the end of | |
| 3081 the region. See |:syn-pattern| below. | |
| 3082 | |
| 3083 Example: > | |
| 3084 :syntax region String start=+"+ skip=+\\"+ end=+"+ | |
| 3085 < | |
| 3086 The start/skip/end patterns and the options can be given in any order. | |
| 3087 There can be zero or one skip pattern. There must be one or more | |
| 3088 start and end patterns. This means that you can omit the skip | |
| 3089 pattern, but you must give at least one start and one end pattern. It | |
| 3090 is allowed to have white space before and after the equal sign | |
| 3091 (although it mostly looks better without white space). | |
| 3092 | |
| 3093 When more than one start pattern is given, a match with one of these | |
| 3094 is sufficient. This means there is an OR relation between the start | |
| 3095 patterns. The last one that matches is used. The same is true for | |
| 3096 the end patterns. | |
| 3097 | |
| 3098 The search for the end pattern starts right after the start pattern. | |
| 3099 Offsets are not used for this. This implies that the match for the | |
| 3100 end pattern will never overlap with the start pattern. | |
| 3101 | |
| 3102 The skip and end pattern can match across line breaks, but since the | |
| 3103 search for the pattern can start in any line it often does not do what | |
| 3104 you want. The skip pattern doesn't avoid a match of an end pattern in | |
| 3105 the next line. Use single-line patterns to avoid trouble. | |
| 3106 | |
| 3107 Note: The decision to start a region is only based on a matching start | |
| 3108 pattern. There is no check for a matching end pattern. This does NOT | |
| 3109 work: > | |
| 3110 :syn region First start="(" end=":" | |
| 3111 :syn region Second start="(" end=";" | |
| 3112 < The Second always matches before the First (last defined pattern has | |
| 3113 higher priority). The Second region then continues until the next | |
| 3114 ';', no matter if there is a ':' before it. Using a match does work: > | |
| 3115 :syn match First "(\_.\{-}:" | |
| 3116 :syn match Second "(\_.\{-};" | |
| 3117 < This pattern matches any character or line break with "\_." and | |
| 3118 repeats that with "\{-}" (repeat as few as possible). | |
| 3119 | |
| 3120 *:syn-keepend* | |
| 3121 By default, a contained match can obscure a match for the end pattern. | |
| 3122 This is useful for nesting. For example, a region that starts with | |
| 3123 "{" and ends with "}", can contain another region. An encountered "}" | |
| 3124 will then end the contained region, but not the outer region: | |
| 3125 { starts outer "{}" region | |
| 3126 { starts contained "{}" region | |
| 3127 } ends contained "{}" region | |
| 3128 } ends outer "{} region | |
| 3129 If you don't want this, the "keepend" argument will make the matching | |
| 3130 of an end pattern of the outer region also end any contained item. | |
| 3131 This makes it impossible to nest the same region, but allows for | |
| 3132 contained items to highlight parts of the end pattern, without causing | |
| 3133 that to skip the match with the end pattern. Example: > | |
| 3134 :syn match vimComment +"[^"]\+$+ | |
| 3135 :syn region vimCommand start="set" end="$" contains=vimComment keepend | |
| 3136 < The "keepend" makes the vimCommand always end at the end of the line, | |
| 3137 even though the contained vimComment includes a match with the <EOL>. | |
| 3138 | |
| 3139 When "keepend" is not used, a match with an end pattern is retried | |
| 3140 after each contained match. When "keepend" is included, the first | |
| 3141 encountered match with an end pattern is used, truncating any | |
| 3142 contained matches. | |
| 3143 *:syn-extend* | |
| 3144 The "keepend" behavior can be changed by using the "extend" argument. | |
| 3145 When an item with "extend" is contained in an item that uses | |
| 3146 "keepend", the "keepend" is ignored and the containing region will be | |
| 3147 extended. | |
| 3148 This can be used to have some contained items extend a region while | |
| 3149 others don't. Example: > | |
| 3150 | |
| 3151 :syn region htmlRef start=+<a>+ end=+</a>+ keepend contains=htmlItem,htmlScript | |
| 3152 :syn match htmlItem +<[^>]*>+ contained | |
| 3153 :syn region htmlScript start=+<script+ end=+</script[^>]*>+ contained extend | |
| 3154 | |
| 3155 < Here the htmlItem item does not make the htmlRef item continue | |
| 3156 further, it is only used to highlight the <> items. The htmlScript | |
| 3157 item does extend the htmlRef item. | |
| 3158 | |
| 3159 Another example: > | |
| 3160 :syn region xmlFold start="<a>" end="</a>" fold transparent keepend extend | |
| 3161 < This defines a region with "keepend", so that its end cannot be | |
| 3162 changed by contained items, like when the "</a>" is matched to | |
| 3163 highlight it differently. But when the xmlFold region is nested (it | |
| 3164 includes itself), the "extend" applies, so that the "</a>" of a nested | |
| 3165 region only ends that region, and not the one it is contained in. | |
| 3166 | |
| 3167 *:syn-excludenl* | |
| 3168 When a pattern for a match or end pattern of a region includes a '$' | |
| 3169 to match the end-of-line, it will make a region item that it is | |
| 3170 contained in continue on the next line. For example, a match with | |
| 3171 "\\$" (backslash at the end of the line) can make a region continue | |
| 3172 that would normally stop at the end of the line. This is the default | |
| 3173 behavior. If this is not wanted, there are two ways to avoid it: | |
| 3174 1. Use "keepend" for the containing item. This will keep all | |
| 3175 contained matches from extending the match or region. It can be | |
| 3176 used when all contained items must not extend the containing item. | |
| 3177 2. Use "excludenl" in the contained item. This will keep that match | |
| 3178 from extending the containing match or region. It can be used if | |
| 3179 only some contained items must not extend the containing item. | |
| 3180 "excludenl" must be given before the pattern it applies to. | |
| 3181 | |
| 3182 *:syn-matchgroup* | |
| 3183 "matchgroup" can be used to highlight the start and/or end pattern | |
| 3184 differently than the body of the region. Example: > | |
| 3185 :syntax region String matchgroup=Quote start=+"+ skip=+\\"+ end=+"+ | |
| 3186 < This will highlight the quotes with the "Quote" group, and the text in | |
| 3187 between with the "String" group. | |
| 3188 The "matchgroup" is used for all start and end patterns that follow, | |
| 3189 until the next "matchgroup". Use "matchgroup=NONE" to go back to not | |
| 3190 using a matchgroup. | |
| 3191 | |
| 3192 In a start or end pattern that is highlighted with "matchgroup" the | |
| 3193 contained items of the region are not used. This can be used to avoid | |
| 3194 that a contained item matches in the start or end pattern match. When | |
| 3195 using "transparent", this does not apply to a start or end pattern | |
| 3196 match that is highlighted with "matchgroup". | |
| 3197 | |
| 3198 Here is an example, which highlights three levels of parentheses in | |
| 3199 different colors: > | |
| 3200 :sy region par1 matchgroup=par1 start=/(/ end=/)/ contains=par2 | |
| 3201 :sy region par2 matchgroup=par2 start=/(/ end=/)/ contains=par3 contained | |
| 3202 :sy region par3 matchgroup=par3 start=/(/ end=/)/ contains=par1 contained | |
| 3203 :hi par1 ctermfg=red guifg=red | |
| 3204 :hi par2 ctermfg=blue guifg=blue | |
| 3205 :hi par3 ctermfg=darkgreen guifg=darkgreen | |
| 3206 | |
| 3207 ============================================================================== | |
| 3208 6. :syntax arguments *:syn-arguments* | |
| 3209 | |
| 3210 The :syntax commands that define syntax items take a number of arguments. | |
| 3211 The common ones are explained here. The arguments may be given in any order | |
| 3212 and may be mixed with patterns. | |
| 3213 | |
| 3214 Not all commands accept all arguments. This table shows which arguments | |

3256 See |hl-Conceal| for highlighting. |
| 7 | 3257 |
| 3258 contained *:syn-contained* | |
| 3259 | |
| 3260 When the "contained" argument is given, this item will not be recognized at | |
| 3261 the top level, but only when it is mentioned in the "contains" field of | |
| 3262 another match. Example: > | |
| 3263 :syntax keyword Todo TODO contained | |
| 3264 :syntax match Comment "//.*" contains=Todo | |
| 3265 | |
| 3266 | |
| 3267 display *:syn-display* | |
| 3268 | |
| 3269 If the "display" argument is given, this item will be skipped when the | |
| 3270 detected highlighting will not be displayed. This will speed up highlighting, | |
| 3271 by skipping this item when only finding the syntax state for the text that is | |
| 3272 to be displayed. | |
| 3273 | |
| 3274 Generally, you can use "display" for match and region items that meet these | |
| 3275 conditions: | |
| 3276 - The item does not continue past the end of a line. Example for C: A region | |
| 3277 for a "/*" comment can't contain "display", because it continues on the next | |
| 3278 line. | |
| 3279 - The item does not contain items that continue past the end of the line or | |
| 3280 make it continue on the next line. | |
| 3281 - The item does not change the size of any item it is contained in. Example | |
| 3282 for C: A match with "\\$" in a preprocessor match can't have "display", | |
| 3283 because it may make that preprocessor match shorter. | |
| 3284 - The item does not allow other items to match that didn't match otherwise, | |
| 3285 and that item may extend the match too far. Example for C: A match for a | |
| 3286 "//" comment can't use "display", because a "/*" inside that comment would | |
| 3287 match then and start a comment which extends past the end of the line. | |
| 3288 | |
| 3289 Examples, for the C language, where "display" can be used: | |
| 3290 - match with a number | |
| 3291 - match with a label | |
| 3292 | |
| 3293 | |
| 3294 transparent *:syn-transparent* | |
| 3295 | |
| 3296 If the "transparent" argument is given, this item will not be highlighted | |
| 3297 itself, but will take the highlighting of the item it is contained in. This | |
| 3298 is useful for syntax items that don't need any highlighting but are used | |
| 3299 only to skip over a part of the text. | |
| 3300 | |
| 3301 The "contains=" argument is also inherited from the item it is contained in, | |
| 3302 unless a "contains" argument is given for the transparent item itself. To | |
| 3303 avoid that unwanted items are contained, use "contains=NONE". Example, which | |
| 3304 highlights words in strings, but makes an exception for "vim": > | |
| 3305 :syn match myString /'[^']*'/ contains=myWord,myVim | |
| 3306 :syn match myWord /\<[a-z]*\>/ contained | |
| 3307 :syn match myVim /\<vim\>/ transparent contained contains=NONE | |
| 3308 :hi link myString String | |
| 3309 :hi link myWord Comment | |
| 3310 Since the "myVim" match comes after "myWord" it is the preferred match (last | |
| 3311 match in the same position overrules an earlier one). The "transparent" | |
| 3312 argument makes the "myVim" match use the same highlighting as "myString". But | |
| 3313 it does not contain anything. If the "contains=NONE" argument would be left | |
| 3314 out, then "myVim" would use the contains argument from myString and allow | |
| 3315 "myWord" to be contained, which will be highlighted as a Constant. This | |
| 3316 happens because a contained match doesn't match inside itself in the same | |
| 3317 position, thus the "myVim" match doesn't overrule the "myWord" match here. | |
| 3318 | |
| 3319 When you look at the colored text, it is like looking at layers of contained | |
| 3320 items. The contained item is on top of the item it is contained in, thus you | |
| 3321 see the contained item. When a contained item is transparent, you can look | |
| 3322 through, thus you see the item it is contained in. In a picture: | |
| 3323 | |
| 3324 look from here | |
| 3325 | |
| 3326 | | | | | | | |
| 3327 V V V V V V | |
| 3328 | |
| 3329 xxxx yyy more contained items | |
| 3330 .................... contained item (transparent) | |
| 3331 ============================= first item | |
| 3332 | |
| 3333 The 'x', 'y' and '=' represent a highlighted syntax item. The '.' represent a | |
| 3334 transparent group. | |
| 3335 | |
| 3336 What you see is: | |
| 3337 | |
| 3338 =======xxxx=======yyy======== | |
| 3339 | |
| 3340 Thus you look through the transparent "....". | |
| 3341 | |
| 3342 | |
| 3343 oneline *:syn-oneline* | |
| 3344 | |
| 3345 The "oneline" argument indicates that the region does not cross a line | |
| 3346 boundary. It must match completely in the current line. However, when the | |
| 3347 region has a contained item that does cross a line boundary, it continues on | |
| 3348 the next line anyway. A contained item can be used to recognize a line | |
| 3349 continuation pattern. But the "end" pattern must still match in the first | |
| 3350 line, otherwise the region doesn't even start. | |
| 3351 | |
| 3352 When the start pattern includes a "\n" to match an end-of-line, the end | |
| 3353 pattern must be found in the same line as where the start pattern ends. The | |
| 3354 end pattern may also include an end-of-line. Thus the "oneline" argument | |
| 3355 means that the end of the start pattern and the start of the end pattern must | |
| 3356 be within one line. This can't be changed by a skip pattern that matches a | |
| 3357 line break. | |
| 3358 | |
| 3359 | |
| 3360 fold *:syn-fold* | |
| 3361 | |
| 1624 | 3362 The "fold" argument makes the fold level increase by one for this item. |
| 7 | 3363 Example: > |
| 3364 :syn region myFold start="{" end="}" transparent fold | |
| 3365 :syn sync fromstart | |
| 3366 :set foldmethod=syntax | |
| 3367 This will make each {} block form one fold. | |
| 3368 | |
| 3369 The fold will start on the line where the item starts, and end where the item | |
| 3370 ends. If the start and end are within the same line, there is no fold. | |
| 3371 The 'foldnestmax' option limits the nesting of syntax folds. | |
| 3372 {not available when Vim was compiled without |+folding| feature} | |
| 3373 | |
| 3374 | |
| 3375 *:syn-contains* *E405* *E406* *E407* *E408* *E409* | |
| 3376 contains={groupname},.. | |
| 3377 | |
| 3378 The "contains" argument is followed by a list of syntax group names. These | |
| 3379 groups will be allowed to begin inside the item (they may extend past the | |
| 3380 containing group's end). This allows for recursive nesting of matches and | |
| 3381 regions. If there is no "contains" argument, no groups will be contained in | |
| 3382 this item. The group names do not need to be defined before they can be used | |
| 3383 here. | |
| 3384 | |
| 3385 contains=ALL | |
| 3386 If the only item in the contains list is "ALL", then all | |
| 3387 groups will be accepted inside the item. | |
| 3388 | |
| 3389 contains=ALLBUT,{group-name},.. | |
| 3390 If the first item in the contains list is "ALLBUT", then all | |
| 3391 groups will be accepted inside the item, except the ones that | |
| 3392 are listed. Example: > | |
| 3393 :syntax region Block start="{" end="}" ... contains=ALLBUT,Function | |
| 3394 | |
| 3395 contains=TOP | |
| 3396 If the first item in the contains list is "TOP", then all | |
| 3397 groups will be accepted that don't have the "contained" | |
| 3398 argument. | |
| 3399 contains=TOP,{group-name},.. | |
| 3400 Like "TOP", but excluding the groups that are listed. | |
| 3401 | |
| 3402 contains=CONTAINED | |
| 3403 If the first item in the contains list is "CONTAINED", then | |
| 3404 all groups will be accepted that have the "contained" | |
| 3405 argument. | |
| 3406 contains=CONTAINED,{group-name},.. | |
| 3407 Like "CONTAINED", but excluding the groups that are | |
| 3408 listed. | |
| 3409 | |
| 3410 | |
| 3411 The {group-name} in the "contains" list can be a pattern. All group names | |
| 3412 that match the pattern will be included (or excluded, if "ALLBUT" is used). | |
| 3413 The pattern cannot contain white space or a ','. Example: > | |
| 3414 ... contains=Comment.*,Keyw[0-3] | |
| 3415 The matching will be done at moment the syntax command is executed. Groups | |
| 3416 that are defined later will not be matched. Also, if the current syntax | |
| 3417 command defines a new group, it is not matched. Be careful: When putting | |
| 3418 syntax commands in a file you can't rely on groups NOT being defined, because | |
| 3419 the file may have been sourced before, and ":syn clear" doesn't remove the | |
| 3420 group names. | |
| 3421 | |
| 3422 The contained groups will also match in the start and end patterns of a | |
| 3423 region. If this is not wanted, the "matchgroup" argument can be used | |
| 3424 |:syn-matchgroup|. The "ms=" and "me=" offsets can be used to change the | |
| 3425 region where contained items do match. Note that this may also limit the | |
| 3426 area that is highlighted | |
| 3427 | |
| 3428 | |
| 3429 containedin={groupname}... *:syn-containedin* | |
| 3430 | |
| 3431 The "containedin" argument is followed by a list of syntax group names. The | |
| 3432 item will be allowed to begin inside these groups. This works as if the | |
| 3433 containing item has a "contains=" argument that includes this item. | |
| 3434 | |
| 3435 The {groupname}... can be used just like for "contains", as explained above. | |
| 3436 | |
| 3437 This is useful when adding a syntax item afterwards. An item can be told to | |
| 3438 be included inside an already existing item, without changing the definition | |
| 3439 of that item. For example, to highlight a word in a C comment after loading | |
| 3440 the C syntax: > | |
| 3441 :syn keyword myword HELP containedin=cComment contained | |
| 3442 Note that "contained" is also used, to avoid that the item matches at the top | |
| 3443 level. | |
| 3444 | |
| 3445 Matches for "containedin" are added to the other places where the item can | |
| 3446 appear. A "contains" argument may also be added as usual. Don't forget that | |
| 3447 keywords never contain another item, thus adding them to "containedin" won't | |
| 3448 work. | |
| 3449 | |
| 3450 | |
| 3451 nextgroup={groupname},.. *:syn-nextgroup* | |
| 3452 | |
| 3453 The "nextgroup" argument is followed by a list of syntax group names, | |
| 3454 separated by commas (just like with "contains", so you can also use patterns). | |
| 3455 | |
| 3456 If the "nextgroup" argument is given, the mentioned syntax groups will be | |
| 3457 tried for a match, after the match or region ends. If none of the groups have | |
| 3458 a match, highlighting continues normally. If there is a match, this group | |
| 3459 will be used, even when it is not mentioned in the "contains" field of the | |
| 3460 current group. This is like giving the mentioned group priority over all | |
| 3461 other groups. Example: > | |
| 3462 :syntax match ccFoobar "Foo.\{-}Bar" contains=ccFoo | |
| 3463 :syntax match ccFoo "Foo" contained nextgroup=ccFiller | |
| 3464 :syntax region ccFiller start="." matchgroup=ccBar end="Bar" contained | |
| 3465 | |
| 3466 This will highlight "Foo" and "Bar" differently, and only when there is a | |
| 3467 "Bar" after "Foo". In the text line below, "f" shows where ccFoo is used for | |
| 3468 highlighting, and "bbb" where ccBar is used. > | |
| 3469 | |
| 3470 Foo asdfasd Bar asdf Foo asdf Bar asdf | |
| 3471 fff bbb fff bbb | |
| 3472 | |
| 3473 Note the use of ".\{-}" to skip as little as possible until the next Bar. | |
| 3474 when ".*" would be used, the "asdf" in between "Bar" and "Foo" would be | |
| 3475 highlighted according to the "ccFoobar" group, because the ccFooBar match | |
| 3476 would include the first "Foo" and the last "Bar" in the line (see |pattern|). | |
| 3477 | |
| 3478 | |
| 3479 skipwhite *:syn-skipwhite* | |
| 3480 skipnl *:syn-skipnl* | |
| 3481 skipempty *:syn-skipempty* | |
| 3482 | |
| 3483 These arguments are only used in combination with "nextgroup". They can be | |
| 3484 used to allow the next group to match after skipping some text: | |
| 1275 | 3485 skipwhite skip over space and tab characters |
| 7 | 3486 skipnl skip over the end of a line |
| 3487 skipempty skip over empty lines (implies a "skipnl") | |
| 3488 | |
| 3489 When "skipwhite" is present, the white space is only skipped if there is no | |
| 3490 next group that matches the white space. | |
| 3491 | |
| 3492 When "skipnl" is present, the match with nextgroup may be found in the next | |
| 3493 line. This only happens when the current item ends at the end of the current | |
| 3494 line! When "skipnl" is not present, the nextgroup will only be found after | |
| 3495 the current item in the same line. | |
| 3496 | |
| 3497 When skipping text while looking for a next group, the matches for other | |
| 3498 groups are ignored. Only when no next group matches, other items are tried | |
| 3499 for a match again. This means that matching a next group and skipping white | |
| 3500 space and <EOL>s has a higher priority than other items. | |
| 3501 | |
| 3502 Example: > | |
| 3503 :syn match ifstart "\<if.*" nextgroup=ifline skipwhite skipempty | |
| 3504 :syn match ifline "[^ \t].*" nextgroup=ifline skipwhite skipempty contained | |
| 3505 :syn match ifline "endif" contained | |
| 3506 Note that the "[^ \t].*" match matches all non-white text. Thus it would also | |
| 3507 match "endif". Therefore the "endif" match is put last, so that it takes | |
| 3508 precedence. | |
| 3509 Note that this example doesn't work for nested "if"s. You need to add | |
| 3510 "contains" arguments to make that work (omitted for simplicity of the | |
| 3511 example). | |

| 7 | 3523 ============================================================================== |
| 3524 7. Syntax patterns *:syn-pattern* *E401* *E402* | |
| 3525 | |
| 3526 In the syntax commands, a pattern must be surrounded by two identical | |
| 3527 characters. This is like it works for the ":s" command. The most common to | |
| 3528 use is the double quote. But if the pattern contains a double quote, you can | |
| 3529 use another character that is not used in the pattern. Examples: > | |
| 3530 :syntax region Comment start="/\*" end="\*/" | |
| 3531 :syntax region String start=+"+ end=+"+ skip=+\\"+ | |
| 3532 | |
| 3533 See |pattern| for the explanation of what a pattern is. Syntax patterns are | |
| 1624 | 3534 always interpreted like the 'magic' option is set, no matter what the actual |
| 7 | 3535 value of 'magic' is. And the patterns are interpreted like the 'l' flag is |
| 3536 not included in 'cpoptions'. This was done to make syntax files portable and | |
| 3537 independent of 'compatible' and 'magic' settings. | |
| 3538 | |
| 3539 Try to avoid patterns that can match an empty string, such as "[a-z]*". | |
| 3540 This slows down the highlighting a lot, because it matches everywhere. | |
| 3541 | |
| 3542 *:syn-pattern-offset* | |
| 3543 The pattern can be followed by a character offset. This can be used to | |
| 3544 change the highlighted part, and to change the text area included in the | |
| 3545 match or region (which only matters when trying to match other items). Both | |
| 3546 are relative to the matched pattern. The character offset for a skip | |
| 3547 pattern can be used to tell where to continue looking for an end pattern. | |
| 3548 | |
| 3549 The offset takes the form of "{what}={offset}" | |
| 3550 The {what} can be one of seven strings: | |
| 3551 | |
| 3552 ms Match Start offset for the start of the matched text | |
| 3553 me Match End offset for the end of the matched text | |
| 3554 hs Highlight Start offset for where the highlighting starts | |
| 3555 he Highlight End offset for where the highlighting ends | |
| 3556 rs Region Start offset for where the body of a region starts | |
| 3557 re Region End offset for where the body of a region ends | |
| 3558 lc Leading Context offset past "leading context" of pattern | |
| 3559 | |
| 3560 The {offset} can be: | |
| 3561 | |
| 3562 s start of the matched pattern | |
| 3563 s+{nr} start of the matched pattern plus {nr} chars to the right | |
| 3564 s-{nr} start of the matched pattern plus {nr} chars to the left | |
| 3565 e end of the matched pattern | |
| 3566 e+{nr} end of the matched pattern plus {nr} chars to the right | |
| 3567 e-{nr} end of the matched pattern plus {nr} chars to the left | |
| 3568 {nr} (for "lc" only): start matching {nr} chars to the left | |
| 3569 | |
| 3570 Examples: "ms=s+1", "hs=e-2", "lc=3". | |
| 3571 | |
| 3572 Although all offsets are accepted after any pattern, they are not always | |
| 3573 meaningful. This table shows which offsets are actually used: | |
| 3574 | |
| 3575 ms me hs he rs re lc ~ | |
| 3576 match item yes yes yes yes - - yes | |
| 3577 region item start yes - yes - yes - yes | |
| 3578 region item skip - yes - - - - yes | |
| 3579 region item end - yes - yes - yes yes | |
| 3580 | |
| 3581 Offsets can be concatenated, with a ',' in between. Example: > | |
| 3582 :syn match String /"[^"]*"/hs=s+1,he=e-1 | |
| 3583 < | |
| 3584 some "string" text | |
| 3585 ^^^^^^ highlighted | |
| 3586 | |
| 3587 Notes: | |
| 3588 - There must be no white space between the pattern and the character | |
| 3589 offset(s). | |
| 3590 - The highlighted area will never be outside of the matched text. | |
| 3591 - A negative offset for an end pattern may not always work, because the end | |
| 3592 pattern may be detected when the highlighting should already have stopped. | |

3595 Vim 7.2 release. |
| 7 | 3596 - The start of a match cannot be in a line other than where the pattern |
| 3597 matched. This doesn't work: "a\nb"ms=e. You can make the highlighting | |
| 3598 start in another line, this does work: "a\nb"hs=e. | |
| 3599 | |
| 3600 Example (match a comment but don't highlight the /* and */): > | |
| 3601 :syntax region Comment start="/\*"hs=e+1 end="\*/"he=s-1 | |
| 3602 < | |
| 3603 /* this is a comment */ | |
| 3604 ^^^^^^^^^^^^^^^^^^^ highlighted | |
| 3605 | |
| 3606 A more complicated Example: > | |
| 3607 :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 | |
| 3608 < | |
| 3609 abcfoostringbarabc | |
| 3610 mmmmmmmmmmm match | |
| 625 | 3611 sssrrreee highlight start/region/end ("Foo", "Exa" and "Bar") |
| 7 | 3612 |
| 3613 Leading context *:syn-lc* *:syn-leading* *:syn-context* | |
| 3614 | |
| 3615 Note: This is an obsolete feature, only included for backwards compatibility | |
| 3616 with previous Vim versions. It's now recommended to use the |/\@<=| construct | |
| 3617 in the pattern. | |
| 3618 | |
| 3619 The "lc" offset specifies leading context -- a part of the pattern that must | |
| 3620 be present, but is not considered part of the match. An offset of "lc=n" will | |
| 3621 cause Vim to step back n columns before attempting the pattern match, allowing | |
| 3622 characters which have already been matched in previous patterns to also be | |
| 3623 used as leading context for this match. This can be used, for instance, to | |
| 3624 specify that an "escaping" character must not precede the match: > | |
| 3625 | |
| 3626 :syn match ZNoBackslash "[^\\]z"ms=s+1 | |
| 3627 :syn match WNoBackslash "[^\\]w"lc=1 | |
| 3628 :syn match Underline "_\+" | |
| 3629 < | |
| 3630 ___zzzz ___wwww | |
| 3631 ^^^ ^^^ matches Underline | |
| 3632 ^ ^ matches ZNoBackslash | |
| 3633 ^^^^ matches WNoBackslash | |
| 3634 | |
| 3635 The "ms" offset is automatically set to the same value as the "lc" offset, | |
| 3636 unless you set "ms" explicitly. | |
| 3637 | |
| 3638 | |
| 3639 Multi-line patterns *:syn-multi-line* | |
| 3640 | |
| 3641 The patterns can include "\n" to match an end-of-line. Mostly this works as | |
| 3642 expected, but there are a few exceptions. | |
| 3643 | |
| 3644 When using a start pattern with an offset, the start of the match is not | |
| 3645 allowed to start in a following line. The highlighting can start in a | |

3647 the match doesn't move to another line. |
| 7 | 3648 |
| 3649 The skip pattern can include the "\n", but the search for an end pattern will | |
| 3650 continue in the first character of the next line, also when that character is | |
| 3651 matched by the skip pattern. This is because redrawing may start in any line | |
| 3652 halfway a region and there is no check if the skip pattern started in a | |
| 3653 previous line. For example, if the skip pattern is "a\nb" and an end pattern | |
| 3654 is "b", the end pattern does match in the second line of this: > | |
| 3655 x x a | |
| 3656 b x x | |
| 3657 Generally this means that the skip pattern should not match any characters | |
| 3658 after the "\n". | |
| 3659 | |
| 3660 | |
| 3661 External matches *:syn-ext-match* | |
| 3662 | |
| 3663 These extra regular expression items are available in region patterns: | |
| 3664 | |
| 3665 */\z(* */\z(\)* *E50* *E52* | |
| 3666 \z(\) Marks the sub-expression as "external", meaning that it is can | |
| 3667 be accessed from another pattern match. Currently only usable | |
| 3668 in defining a syntax region start pattern. | |
| 3669 | |
| 3670 */\z1* */\z2* */\z3* */\z4* */\z5* | |
| 3671 \z1 ... \z9 */\z6* */\z7* */\z8* */\z9* *E66* *E67* | |
| 3672 Matches the same string that was matched by the corresponding | |
| 3673 sub-expression in a previous start pattern match. | |
| 3674 | |
| 3675 Sometimes the start and end patterns of a region need to share a common | |
| 3676 sub-expression. A common example is the "here" document in Perl and many Unix | |
| 3677 shells. This effect can be achieved with the "\z" special regular expression | |
| 3678 items, which marks a sub-expression as "external", in the sense that it can be | |
| 3679 referenced from outside the pattern in which it is defined. The here-document | |
| 3680 example, for instance, can be done like this: > | |
| 3681 :syn region hereDoc start="<<\z(\I\i*\)" end="^\z1$" | |
| 3682 | |
| 3683 As can be seen here, the \z actually does double duty. In the start pattern, | |
| 3684 it marks the "\(\I\i*\)" sub-expression as external; in the end pattern, it | |
| 3685 changes the \1 back-reference into an external reference referring to the | |
| 3686 first external sub-expression in the start pattern. External references can | |
| 3687 also be used in skip patterns: > | |
| 3688 :syn region foo start="start \(\I\i*\)" skip="not end \z1" end="end \z1" | |
| 3689 | |
| 3690 Note that normal and external sub-expressions are completely orthogonal and | |
| 3691 indexed separately; for instance, if the pattern "\z(..\)\(..\)" is applied | |
| 3692 to the string "aabb", then \1 will refer to "bb" and \z1 will refer to "aa". | |
| 3693 Note also that external sub-expressions cannot be accessed as back-references | |
| 3694 within the same pattern like normal sub-expressions. If you want to use one | |
| 3695 sub-expression as both a normal and an external sub-expression, you can nest | |
| 3696 the two, as in "\(\z(...\)\)". | |
| 3697 | |
| 3698 Note that only matches within a single line can be used. Multi-line matches | |
| 3699 cannot be referred to. | |
| 3700 | |
| 3701 ============================================================================== | |
| 3702 8. Syntax clusters *:syn-cluster* *E400* | |
| 3703 | |
| 3704 :sy[ntax] cluster {cluster-name} [contains={group-name}..] | |
| 3705 [add={group-name}..] | |
| 3706 [remove={group-name}..] | |
| 3707 | |
| 3708 This command allows you to cluster a list of syntax groups together under a | |
| 3709 single name. | |
| 3710 | |
| 3711 contains={group-name}.. | |
| 3712 The cluster is set to the specified list of groups. | |
| 3713 add={group-name}.. | |
| 3714 The specified groups are added to the cluster. | |
| 3715 remove={group-name}.. | |
| 3716 The specified groups are removed from the cluster. | |
| 3717 | |
| 1624 | 3718 A cluster so defined may be referred to in a contains=.., containedin=.., |
| 3719 nextgroup=.., add=.. or remove=.. list with a "@" prefix. You can also use | |
| 3720 this notation to implicitly declare a cluster before specifying its contents. | |
| 7 | 3721 |
| 3722 Example: > | |
| 3723 :syntax match Thing "# [^#]\+ #" contains=@ThingMembers | |
| 3724 :syntax cluster ThingMembers contains=ThingMember1,ThingMember2 | |
| 3725 | |
| 3726 As the previous example suggests, modifications to a cluster are effectively | |
| 3727 retroactive; the membership of the cluster is checked at the last minute, so | |
| 3728 to speak: > | |
| 3729 :syntax keyword A aaa | |
| 3730 :syntax keyword B bbb | |
| 3731 :syntax cluster AandB contains=A | |
| 3732 :syntax match Stuff "( aaa bbb )" contains=@AandB | |
| 3733 :syntax cluster AandB add=B " now both keywords are matched in Stuff | |
| 3734 | |
| 3735 This also has implications for nested clusters: > | |
| 3736 :syntax keyword A aaa | |
| 3737 :syntax keyword B bbb | |
| 3738 :syntax cluster SmallGroup contains=B | |
| 3739 :syntax cluster BigGroup contains=A,@SmallGroup | |
| 3740 :syntax match Stuff "( aaa bbb )" contains=@BigGroup | |
| 3741 :syntax cluster BigGroup remove=B " no effect, since B isn't in BigGroup | |
| 3742 :syntax cluster SmallGroup remove=B " now bbb isn't matched within Stuff | |
| 3743 | |
| 3744 ============================================================================== | |
| 3745 9. Including syntax files *:syn-include* *E397* | |
| 3746 | |
| 3747 It is often useful for one language's syntax file to include a syntax file for | |
| 3748 a related language. Depending on the exact relationship, this can be done in | |
| 3749 two different ways: | |
| 3750 | |
| 3751 - If top-level syntax items in the included syntax file are to be | |
| 3752 allowed at the top level in the including syntax, you can simply use | |
| 3753 the |:runtime| command: > | |
| 3754 | |
| 3755 " In cpp.vim: | |
| 3756 :runtime! syntax/c.vim | |
| 3757 :unlet b:current_syntax | |
| 3758 | |
| 3759 < - If top-level syntax items in the included syntax file are to be | |
| 3760 contained within a region in the including syntax, you can use the | |
| 3761 ":syntax include" command: | |
| 3762 | |
| 3763 :sy[ntax] include [@{grouplist-name}] {file-name} | |
| 3764 | |
| 3765 All syntax items declared in the included file will have the | |
| 3766 "contained" flag added. In addition, if a group list is specified, | |
| 3767 all top-level syntax items in the included file will be added to | |
| 3768 that list. > | |
| 3769 | |
| 3770 " In perl.vim: | |
| 3771 :syntax include @Pod <sfile>:p:h/pod.vim | |
| 3772 :syntax region perlPOD start="^=head" end="^=cut" contains=@Pod | |
| 3773 < | |
| 3774 When {file-name} is an absolute path (starts with "/", "c:", "$VAR" | |
| 3775 or "<sfile>") that file is sourced. When it is a relative path | |
| 3776 (e.g., "syntax/pod.vim") the file is searched for in 'runtimepath'. | |
| 3777 All matching files are loaded. Using a relative path is | |
| 3778 recommended, because it allows a user to replace the included file | |
| 3779 with his own version, without replacing the file that does the ":syn | |
| 3780 include". | |
| 3781 | |
| 3782 ============================================================================== | |
| 3783 10. Synchronizing *:syn-sync* *E403* *E404* | |
| 3784 | |
| 3785 Vim wants to be able to start redrawing in any position in the document. To | |
| 3786 make this possible it needs to know the syntax state at the position where | |
| 3787 redrawing starts. | |
| 3788 | |
| 3789 :sy[ntax] sync [ccomment [group-name] | minlines={N} | ...] | |
| 3790 | |
| 3791 There are four ways to synchronize: | |
| 3792 1. Always parse from the start of the file. | |
| 3793 |:syn-sync-first| | |
| 3794 2. Based on C-style comments. Vim understands how C-comments work and can | |
| 3795 figure out if the current line starts inside or outside a comment. | |
| 3796 |:syn-sync-second| | |
| 3797 3. Jumping back a certain number of lines and start parsing there. | |
| 3798 |:syn-sync-third| | |
| 3799 4. Searching backwards in the text for a pattern to sync on. | |
| 3800 |:syn-sync-fourth| | |
| 3801 | |
| 3802 *:syn-sync-maxlines* *:syn-sync-minlines* | |
| 3803 For the last three methods, the line range where the parsing can start is | |
| 3804 limited by "minlines" and "maxlines". | |
| 3805 | |
| 3806 If the "minlines={N}" argument is given, the parsing always starts at least | |
| 3807 that many lines backwards. This can be used if the parsing may take a few | |
| 3808 lines before it's correct, or when it's not possible to use syncing. | |
| 3809 | |
| 3810 If the "maxlines={N}" argument is given, the number of lines that are searched | |
| 3811 for a comment or syncing pattern is restricted to N lines backwards (after | |
| 3812 adding "minlines"). This is useful if you have few things to sync on and a | |
| 3813 slow machine. Example: > | |
| 3814 :syntax sync ccomment maxlines=500 | |
| 3815 < | |
| 3816 *:syn-sync-linebreaks* | |
| 3817 When using a pattern that matches multiple lines, a change in one line may | |
| 3818 cause a pattern to no longer match in a previous line. This means has to | |
| 3819 start above where the change was made. How many lines can be specified with | |
| 3820 the "linebreaks" argument. For example, when a pattern may include one line | |
| 3821 break use this: > | |
| 3822 :syntax sync linebreaks=1 | |
| 3823 The result is that redrawing always starts at least one line before where a | |
| 3824 change was made. The default value for "linebreaks" is zero. Usually the | |
| 3825 value for "minlines" is bigger than "linebreaks". | |
| 3826 | |
| 3827 | |
| 3828 First syncing method: *:syn-sync-first* | |
| 3829 > | |
| 3830 :syntax sync fromstart | |
| 3831 | |
| 3832 The file will be parsed from the start. This makes syntax highlighting | |
| 3833 accurate, but can be slow for long files. Vim caches previously parsed text, | |
| 3834 so that it's only slow when parsing the text for the first time. However, | |
| 3835 when making changes some part of the next needs to be parsed again (worst | |
| 3836 case: to the end of the file). | |
| 3837 | |
| 3838 Using "fromstart" is equivalent to using "minlines" with a very large number. | |
| 3839 | |
| 3840 | |
| 3841 Second syncing method: *:syn-sync-second* *:syn-sync-ccomment* | |
| 3842 | |
| 3843 For the second method, only the "ccomment" argument needs to be given. | |
| 3844 Example: > | |
| 3845 :syntax sync ccomment | |
| 3846 | |
| 3847 When Vim finds that the line where displaying starts is inside a C-style | |
| 3848 comment, the last region syntax item with the group-name "Comment" will be | |
| 3849 used. This requires that there is a region with the group-name "Comment"! | |
| 3850 An alternate group name can be specified, for example: > | |
| 3851 :syntax sync ccomment javaComment | |
| 3852 This means that the last item specified with "syn region javaComment" will be | |
| 3853 used for the detected C comment region. This only works properly if that | |
| 3854 region does have a start pattern "\/*" and an end pattern "*\/". | |
| 3855 | |
| 3856 The "maxlines" argument can be used to restrict the search to a number of | |
| 3857 lines. The "minlines" argument can be used to at least start a number of | |
| 3858 lines back (e.g., for when there is some construct that only takes a few | |
| 3859 lines, but it hard to sync on). | |
| 3860 | |
| 3861 Note: Syncing on a C comment doesn't work properly when strings are used | |
| 3862 that cross a line and contain a "*/". Since letting strings cross a line | |
| 3863 is a bad programming habit (many compilers give a warning message), and the | |
| 3864 chance of a "*/" appearing inside a comment is very small, this restriction | |
| 3865 is hardly ever noticed. | |
| 3866 | |
| 3867 | |
| 3868 Third syncing method: *:syn-sync-third* | |
| 3869 | |
| 3870 For the third method, only the "minlines={N}" argument needs to be given. | |
| 3871 Vim will subtract {N} from the line number and start parsing there. This | |
| 3872 means {N} extra lines need to be parsed, which makes this method a bit slower. | |
| 3873 Example: > | |
| 3874 :syntax sync minlines=50 | |
| 3875 | |
| 3876 "lines" is equivalent to "minlines" (used by older versions). | |
| 3877 | |
| 3878 | |
| 3879 Fourth syncing method: *:syn-sync-fourth* | |
| 3880 | |
| 3881 The idea is to synchronize on the end of a few specific regions, called a | |
| 3882 sync pattern. Only regions can cross lines, so when we find the end of some | |
| 3883 region, we might be able to know in which syntax item we are. The search | |
| 3884 starts in the line just above the one where redrawing starts. From there | |
| 3885 the search continues backwards in the file. | |
| 3886 | |
| 3887 This works just like the non-syncing syntax items. You can use contained | |
| 3888 matches, nextgroup, etc. But there are a few differences: | |
| 3889 - Keywords cannot be used. | |
| 3890 - The syntax items with the "sync" keyword form a completely separated group | |
| 3891 of syntax items. You can't mix syncing groups and non-syncing groups. | |
| 3892 - The matching works backwards in the buffer (line by line), instead of | |
| 3893 forwards. | |
| 3894 - A line continuation pattern can be given. It is used to decide which group | |
| 3895 of lines need to be searched like they were one line. This means that the | |
| 3896 search for a match with the specified items starts in the first of the | |
| 3897 consecutive that contain the continuation pattern. | |
| 3898 - When using "nextgroup" or "contains", this only works within one line (or | |
| 3899 group of continued lines). | |
| 3900 - When using a region, it must start and end in the same line (or group of | |
| 3901 continued lines). Otherwise the end is assumed to be at the end of the | |
| 3902 line (or group of continued lines). | |
| 3903 - When a match with a sync pattern is found, the rest of the line (or group of | |
| 3904 continued lines) is searched for another match. The last match is used. | |
| 3905 This is used when a line can contain both the start end the end of a region | |
| 3906 (e.g., in a C-comment like /* this */, the last "*/" is used). | |
| 3907 | |
| 3908 There are two ways how a match with a sync pattern can be used: | |
| 3909 1. Parsing for highlighting starts where redrawing starts (and where the | |
| 3910 search for the sync pattern started). The syntax group that is expected | |
| 3911 to be valid there must be specified. This works well when the regions | |
| 3912 that cross lines cannot contain other regions. | |
| 3913 2. Parsing for highlighting continues just after the match. The syntax group | |
| 3914 that is expected to be present just after the match must be specified. | |
| 3915 This can be used when the previous method doesn't work well. It's much | |
| 3916 slower, because more text needs to be parsed. | |
| 3917 Both types of sync patterns can be used at the same time. | |
| 3918 | |
| 3919 Besides the sync patterns, other matches and regions can be specified, to | |
| 3920 avoid finding unwanted matches. | |
| 3921 | |
| 3922 [The reason that the sync patterns are given separately, is that mostly the | |
| 3923 search for the sync point can be much simpler than figuring out the | |
| 3924 highlighting. The reduced number of patterns means it will go (much) | |
| 3925 faster.] | |
| 3926 | |
| 3927 *syn-sync-grouphere* *E393* *E394* | |
| 3928 :syntax sync match {sync-group-name} grouphere {group-name} "pattern" .. | |
| 3929 | |
| 3930 Define a match that is used for syncing. {group-name} is the | |
| 3931 name of a syntax group that follows just after the match. Parsing | |
| 3932 of the text for highlighting starts just after the match. A region | |
| 3933 must exist for this {group-name}. The first one defined will be used. | |
| 3934 "NONE" can be used for when there is no syntax group after the match. | |
| 3935 | |
| 3936 *syn-sync-groupthere* | |
| 3937 :syntax sync match {sync-group-name} groupthere {group-name} "pattern" .. | |
| 3938 | |
| 3939 Like "grouphere", but {group-name} is the name of a syntax group that | |
| 3940 is to be used at the start of the line where searching for the sync | |
| 3941 point started. The text between the match and the start of the sync | |
| 3942 pattern searching is assumed not to change the syntax highlighting. | |
| 3943 For example, in C you could search backwards for "/*" and "*/". If | |
| 3944 "/*" is found first, you know that you are inside a comment, so the | |
| 3945 "groupthere" is "cComment". If "*/" is found first, you know that you | |
| 3946 are not in a comment, so the "groupthere" is "NONE". (in practice | |
| 3947 it's a bit more complicated, because the "/*" and "*/" could appear | |
| 3948 inside a string. That's left as an exercise to the reader...). | |
| 3949 | |
| 3950 :syntax sync match .. | |
| 3951 :syntax sync region .. | |
| 3952 | |
| 3953 Without a "groupthere" argument. Define a region or match that is | |
| 3954 skipped while searching for a sync point. | |
| 3955 | |
| 856 | 3956 *syn-sync-linecont* |
| 7 | 3957 :syntax sync linecont {pattern} |
| 3958 | |
| 3959 When {pattern} matches in a line, it is considered to continue in | |
| 3960 the next line. This means that the search for a sync point will | |
| 3961 consider the lines to be concatenated. | |
| 3962 | |
| 3963 If the "maxlines={N}" argument is given too, the number of lines that are | |
| 3964 searched for a match is restricted to N. This is useful if you have very | |
| 3965 few things to sync on and a slow machine. Example: > | |
| 3966 :syntax sync maxlines=100 | |
| 3967 | |
| 3968 You can clear all sync settings with: > | |
| 3969 :syntax sync clear | |
| 3970 | |
| 3971 You can clear specific sync patterns with: > | |
| 3972 :syntax sync clear {sync-group-name} .. | |
| 3973 | |
| 3974 ============================================================================== | |
| 3975 11. Listing syntax items *:syntax* *:sy* *:syn* *:syn-list* | |
| 3976 | |
| 534 | 3977 This command lists all the syntax items: > |
| 7 | 3978 |
| 3979 :sy[ntax] [list] | |
| 3980 | |
| 3981 To show the syntax items for one syntax group: > | |
| 3982 | |
| 3983 :sy[ntax] list {group-name} | |
| 3984 | |
| 2581 | 3985 To list the syntax groups in one cluster: *E392* > |
| 7 | 3986 |
| 3987 :sy[ntax] list @{cluster-name} | |
| 3988 | |
| 3989 See above for other arguments for the ":syntax" command. | |
| 3990 | |
| 3991 Note that the ":syntax" command can be abbreviated to ":sy", although ":syn" | |
| 3992 is mostly used, because it looks better. | |
| 3993 | |
| 3994 ============================================================================== | |
| 3995 12. Highlight command *:highlight* *:hi* *E28* *E411* *E415* | |
| 3996 | |
| 3997 There are three types of highlight groups: | |
| 3998 - The ones used for specific languages. For these the name starts with the | |
| 3999 name of the language. Many of these don't have any attributes, but are | |
| 4000 linked to a group of the second type. | |
| 4001 - The ones used for all syntax languages. | |
| 4002 - The ones used for the 'highlight' option. | |
| 4003 *hitest.vim* | |
| 4004 You can see all the groups currently active with this command: > | |
| 4005 :so $VIMRUNTIME/syntax/hitest.vim | |
| 4006 This will open a new window containing all highlight group names, displayed | |
| 4007 in their own color. | |
| 4008 | |
| 4009 *:colo* *:colorscheme* *E185* | |
| 2152 | 4010 :colo[rscheme] Output the name of the currently active color scheme. |
| 4011 This is basically the same as > | |
| 4012 :echo g:colors_name | |
| 4013 < In case g:colors_name has not been defined :colo will | |
| 4014 output "default". When compiled without the |+eval| | |
| 4015 feature it will output "unknown". | |
| 4016 | |
| 7 | 4017 :colo[rscheme] {name} Load color scheme {name}. This searches 'runtimepath' |
| 4018 for the file "colors/{name}.vim. The first one that | |
| 4019 is found is loaded. | |

| 4030 :hi[ghlight] List all the current highlight groups that have | |
| 4031 attributes set. | |
| 4032 | |
| 4033 :hi[ghlight] {group-name} | |
| 4034 List one highlight group. | |
| 4035 | |
| 4036 :hi[ghlight] clear Reset all highlighting to the defaults. Removes all | |
| 4037 highlighting for groups added by the user! | |
| 4038 Uses the current value of 'background' to decide which | |
| 4039 default colors to use. | |
| 4040 | |
| 4041 :hi[ghlight] clear {group-name} | |
| 4042 :hi[ghlight] {group-name} NONE | |
| 4043 Disable the highlighting for one highlight group. It | |
| 4044 is _not_ set back to the default colors. | |
| 4045 | |
| 4046 :hi[ghlight] [default] {group-name} {key}={arg} .. | |
| 4047 Add a highlight group, or change the highlighting for | |
| 4048 an existing group. | |
| 4049 See |highlight-args| for the {key}={arg} arguments. | |
| 4050 See |:highlight-default| for the optional [default] | |
| 4051 argument. | |
| 4052 | |
| 4053 Normally a highlight group is added once when starting up. This sets the | |
| 4054 default values for the highlighting. After that, you can use additional | |
| 4055 highlight commands to change the arguments that you want to set to non-default | |
| 4056 values. The value "NONE" can be used to switch the value off or go back to | |
| 4057 the default value. | |
| 4058 | |
| 4059 A simple way to change colors is with the |:colorscheme| command. This loads | |
| 4060 a file with ":highlight" commands such as this: > | |
| 4061 | |
| 4062 :hi Comment gui=bold | |
| 4063 | |
| 4064 Note that all settings that are not included remain the same, only the | |
| 4065 specified field is used, and settings are merged with previous ones. So, the | |
| 4066 result is like this single command has been used: > | |
| 4067 :hi Comment term=bold ctermfg=Cyan guifg=#80a0ff gui=bold | |
| 4068 < | |
| 856 | 4069 *:highlight-verbose* |
| 448 | 4070 When listing a highlight group and 'verbose' is non-zero, the listing will |
| 4071 also tell where it was last set. Example: > | |
| 4072 :verbose hi Comment | |
| 4073 < Comment xxx term=bold ctermfg=4 guifg=Blue ~ | |
| 856 | 4074 Last set from /home/mool/vim/vim7/runtime/syntax/syncolor.vim ~ |
| 448 | 4075 |
| 484 | 4076 When ":hi clear" is used then the script where this command is used will be |
| 4077 mentioned for the default values. See |:verbose-cmd| for more information. | |
| 448 | 4078 |
| 7 | 4079 *highlight-args* *E416* *E417* *E423* |
| 4080 There are three types of terminals for highlighting: | |
| 4081 term a normal terminal (vt100, xterm) | |
| 4082 cterm a color terminal (MS-DOS console, color-xterm, these have the "Co" | |
| 4083 termcap entry) | |
| 4084 gui the GUI | |
| 4085 | |
| 4086 For each type the highlighting can be given. This makes it possible to use | |
| 4087 the same syntax file on all terminals, and use the optimal highlighting. | |
| 4088 | |
| 4089 1. highlight arguments for normal terminals | |
| 4090 | |
| 301 | 4091 *bold* *underline* *undercurl* |
| 4092 *inverse* *italic* *standout* | |
| 7 | 4093 term={attr-list} *attr-list* *highlight-term* *E418* |
| 4094 attr-list is a comma separated list (without spaces) of the | |
| 4095 following items (in any order): | |
| 4096 bold | |
| 4097 underline | |
| 217 | 4098 undercurl not always available |
| 7 | 4099 reverse |
| 4100 inverse same as reverse | |
| 4101 italic | |
| 4102 standout | |
| 4103 NONE no attributes used (used to reset it) | |
| 4104 | |
| 4105 Note that "bold" can be used here and by using a bold font. They | |
| 4106 have the same effect. | |
| 217 | 4107 "undercurl" is a curly underline. When "undercurl" is not possible |
| 4108 then "underline" is used. In general "undercurl" is only available in | |
| 819 | 4109 the GUI. The color is set with |highlight-guisp|. |
| 7 | 4110 |
| 4111 start={term-list} *highlight-start* *E422* | |
| 4112 stop={term-list} *term-list* *highlight-stop* | |
| 4113 These lists of terminal codes can be used to get | |
| 4114 non-standard attributes on a terminal. | |
| 4115 | |
| 4116 The escape sequence specified with the "start" argument | |
| 4117 is written before the characters in the highlighted | |
| 4118 area. It can be anything that you want to send to the | |
| 4119 terminal to highlight this area. The escape sequence | |
| 4120 specified with the "stop" argument is written after the | |
| 4121 highlighted area. This should undo the "start" argument. | |
| 4122 Otherwise the screen will look messed up. | |
| 4123 | |
| 4124 The {term-list} can have two forms: | |
| 4125 | |
| 4126 1. A string with escape sequences. | |
| 4127 This is any string of characters, except that it can't start with | |
| 4128 "t_" and blanks are not allowed. The <> notation is recognized | |
| 4129 here, so you can use things like "<Esc>" and "<Space>". Example: | |
| 4130 start=<Esc>[27h;<Esc>[<Space>r; | |
| 4131 | |
| 4132 2. A list of terminal codes. | |
| 4133 Each terminal code has the form "t_xx", where "xx" is the name of | |
| 4134 the termcap entry. The codes have to be separated with commas. | |
| 4135 White space is not allowed. Example: | |
| 4136 start=t_C1,t_BL | |
| 4137 The terminal codes must exist for this to work. | |
| 4138 | |
| 4139 | |
| 4140 2. highlight arguments for color terminals | |
| 4141 | |
| 4142 cterm={attr-list} *highlight-cterm* | |
| 4143 See above for the description of {attr-list} |attr-list|. | |
| 4144 The "cterm" argument is likely to be different from "term", when | |
| 4145 colors are used. For example, in a normal terminal comments could | |
| 4146 be underlined, in a color terminal they can be made Blue. | |
| 4147 Note: Many terminals (e.g., DOS console) can't mix these attributes | |
| 4148 with coloring. Use only one of "cterm=" OR "ctermfg=" OR "ctermbg=". | |
| 4149 | |
| 4150 ctermfg={color-nr} *highlight-ctermfg* *E421* | |
| 4151 ctermbg={color-nr} *highlight-ctermbg* | |
| 4152 The {color-nr} argument is a color number. Its range is zero to | |
| 4153 (not including) the number given by the termcap entry "Co". | |
| 4154 The actual color with this number depends on the type of terminal | |
| 4155 and its settings. Sometimes the color also depends on the settings of | |
| 4156 "cterm". For example, on some systems "cterm=bold ctermfg=3" gives | |
| 4157 another color, on others you just get color 3. | |
| 4158 | |
| 4159 For an xterm this depends on your resources, and is a bit | |
| 4160 unpredictable. See your xterm documentation for the defaults. The | |
| 4161 colors for a color-xterm can be changed from the .Xdefaults file. | |
| 4162 Unfortunately this means that it's not possible to get the same colors | |
| 4163 for each user. See |xterm-color| for info about color xterms. | |
| 4164 | |
| 4165 The MSDOS standard colors are fixed (in a console window), so these | |
| 4166 have been used for the names. But the meaning of color names in X11 | |
| 4167 are fixed, so these color settings have been used, to make the | |
| 4168 highlighting settings portable (complicated, isn't it?). The | |
| 4169 following names are recognized, with the color number used: | |
| 4170 | |
| 4171 *cterm-colors* | |
| 4172 NR-16 NR-8 COLOR NAME ~ | |
| 4173 0 0 Black | |
| 4174 1 4 DarkBlue | |
| 4175 2 2 DarkGreen | |
| 4176 3 6 DarkCyan | |
| 4177 4 1 DarkRed | |
| 4178 5 5 DarkMagenta | |
| 4179 6 3 Brown, DarkYellow | |
| 4180 7 7 LightGray, LightGrey, Gray, Grey | |
| 4181 8 0* DarkGray, DarkGrey | |
| 4182 9 4* Blue, LightBlue | |
| 4183 10 2* Green, LightGreen | |
| 4184 11 6* Cyan, LightCyan | |
| 4185 12 1* Red, LightRed | |
| 4186 13 5* Magenta, LightMagenta | |
| 4187 14 3* Yellow, LightYellow | |
| 4188 15 7* White | |
| 4189 | |
| 4190 The number under "NR-16" is used for 16-color terminals ('t_Co' | |
| 4191 greater than or equal to 16). The number under "NR-8" is used for | |
| 4192 8-color terminals ('t_Co' less than 16). The '*' indicates that the | |
| 4193 bold attribute is set for ctermfg. In many 8-color terminals (e.g., | |
| 4194 "linux"), this causes the bright colors to appear. This doesn't work | |
| 4195 for background colors! Without the '*' the bold attribute is removed. | |
| 4196 If you want to set the bold attribute in a different way, put a | |
| 4197 "cterm=" argument AFTER the "ctermfg=" or "ctermbg=" argument. Or use | |
| 4198 a number instead of a color name. | |
| 4199 | |
| 4200 The case of the color names is ignored. | |
| 4201 Note that for 16 color ansi style terminals (including xterms), the | |
| 237 | 4202 numbers in the NR-8 column is used. Here '*' means 'add 8' so that Blue |
| 7 | 4203 is 12, DarkGray is 8 etc. |
| 4204 | |
| 4205 Note that for some color terminals these names may result in the wrong | |
| 4206 colors! | |
| 4207 | |
| 4208 *:hi-normal-cterm* | |
| 4209 When setting the "ctermfg" or "ctermbg" colors for the Normal group, | |
| 4210 these will become the colors used for the non-highlighted text. | |
| 4211 Example: > | |
| 4212 :highlight Normal ctermfg=grey ctermbg=darkblue | |
| 4213 < When setting the "ctermbg" color for the Normal group, the | |
| 4214 'background' option will be adjusted automatically. This causes the | |
| 4215 highlight groups that depend on 'background' to change! This means | |
| 4216 you should set the colors for Normal first, before setting other | |
| 4217 colors. | |
| 4218 When a colorscheme is being used, changing 'background' causes it to | |
| 4219 be reloaded, which may reset all colors (including Normal). First | |

4220 delete the "g:colors_name" variable when you don't want this. |
| 7 | 4221 |
| 4222 When you have set "ctermfg" or "ctermbg" for the Normal group, Vim | |
| 4223 needs to reset the color when exiting. This is done with the "op" | |
| 4224 termcap entry |t_op|. If this doesn't work correctly, try setting the | |
| 4225 't_op' option in your .vimrc. | |
| 4226 *E419* *E420* | |
| 4227 When Vim knows the normal foreground and background colors, "fg" and | |
| 4228 "bg" can be used as color names. This only works after setting the | |
| 4229 colors for the Normal group and for the MS-DOS console. Example, for | |
| 4230 reverse video: > | |
| 4231 :highlight Visual ctermfg=bg ctermbg=fg | |
| 4232 < Note that the colors are used that are valid at the moment this | |
| 4233 command are given. If the Normal group colors are changed later, the | |
| 4234 "fg" and "bg" colors will not be adjusted. | |
| 4235 | |
| 4236 | |
| 4237 3. highlight arguments for the GUI | |
| 4238 | |
| 4239 gui={attr-list} *highlight-gui* | |
| 4240 These give the attributes to use in the GUI mode. | |
| 4241 See |attr-list| for a description. | |
| 4242 Note that "bold" can be used here and by using a bold font. They | |
| 4243 have the same effect. | |
| 4244 Note that the attributes are ignored for the "Normal" group. | |
| 4245 | |
| 4246 font={font-name} *highlight-font* | |
| 4247 font-name is the name of a font, as it is used on the system Vim | |
| 4248 runs on. For X11 this is a complicated name, for example: > | |
| 4249 font=-misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1 | |
| 4250 < | |
| 4251 The font-name "NONE" can be used to revert to the default font. | |
| 4252 When setting the font for the "Normal" group, this becomes the default | |
| 4253 font (until the 'guifont' option is changed; the last one set is | |
| 4254 used). | |
| 4255 The following only works with Motif and Athena, not with other GUIs: | |
| 4256 When setting the font for the "Menu" group, the menus will be changed. | |
| 4257 When setting the font for the "Tooltip" group, the tooltips will be | |
| 4258 changed. | |
| 4259 All fonts used, except for Menu and Tooltip, should be of the same | |
| 4260 character size as the default font! Otherwise redrawing problems will | |
| 4261 occur. | |
| 4262 | |
| 4263 guifg={color-name} *highlight-guifg* | |
| 4264 guibg={color-name} *highlight-guibg* | |
| 217 | 4265 guisp={color-name} *highlight-guisp* |
| 4266 These give the foreground (guifg), background (guibg) and special | |
| 642 | 4267 (guisp) color to use in the GUI. "guisp" is used for undercurl. |
| 4268 There are a few special names: | |
| 7 | 4269 NONE no color (transparent) |
| 4270 bg use normal background color | |
| 4271 background use normal background color | |
| 4272 fg use normal foreground color | |
| 4273 foreground use normal foreground color | |
| 4274 To use a color name with an embedded space or other special character, | |
| 4275 put it in single quotes. The single quote cannot be used then. | |
| 4276 Example: > | |
| 4277 :hi comment guifg='salmon pink' | |
| 4278 < | |
| 4279 *gui-colors* | |
| 4280 Suggested color names (these are available on most systems): | |
| 4281 Red LightRed DarkRed | |
| 4282 Green LightGreen DarkGreen SeaGreen | |
| 4283 Blue LightBlue DarkBlue SlateBlue | |
| 4284 Cyan LightCyan DarkCyan | |
| 4285 Magenta LightMagenta DarkMagenta | |
| 4286 Yellow LightYellow Brown DarkYellow | |
| 4287 Gray LightGray DarkGray | |
| 4288 Black White | |
| 4289 Orange Purple Violet | |
| 4290 | |
| 4291 In the Win32 GUI version, additional system colors are available. See | |
| 4292 |win32-colors|. | |
| 4293 | |
| 4294 You can also specify a color by its Red, Green and Blue values. | |
| 4295 The format is "#rrggbb", where | |
| 4296 "rr" is the Red value | |
| 217 | 4297 "gg" is the Green value |
| 7 | 4298 "bb" is the Blue value |
| 4299 All values are hexadecimal, range from "00" to "ff". Examples: > | |
| 4300 :highlight Comment guifg=#11f0c3 guibg=#ff00ff | |
| 4301 < | |
| 4302 *highlight-groups* *highlight-default* | |
| 4303 These are the default highlighting groups. These groups are used by the | |
| 4304 'highlight' option default. Note that the highlighting depends on the value | |
| 4305 of 'background'. You can see the current settings with the ":highlight" | |
| 4306 command. | |

| 4410 *hl-Visual* | |
| 4411 Visual Visual mode selection | |
| 4412 *hl-VisualNOS* | |
| 4413 VisualNOS Visual mode selection when vim is "Not Owning the Selection". | |
| 4414 Only X11 Gui's |gui-x11| and |xterm-clipboard| supports this. | |
| 4415 *hl-WarningMsg* | |
| 4416 WarningMsg warning messages | |
| 4417 *hl-WildMenu* | |
| 4418 WildMenu current match in 'wildmenu' completion | |
| 4419 | |
| 523 | 4420 *hl-User1* *hl-User1..9* *hl-User9* |
| 7 | 4421 The 'statusline' syntax allows the use of 9 different highlights in the |
| 237 | 4422 statusline and ruler (via 'rulerformat'). The names are User1 to User9. |
| 7 | 4423 |
| 1624 | 4424 For the GUI you can use the following groups to set the colors for the menu, |
| 7 | 4425 scrollbars and tooltips. They don't have defaults. This doesn't work for the |
| 4426 Win32 GUI. Only three highlight arguments have any effect here: font, guibg, | |
| 4427 and guifg. | |
| 4428 | |
| 4429 *hl-Menu* | |
| 4430 Menu Current font, background and foreground colors of the menus. | |
| 4431 Also used for the toolbar. | |
| 4432 Applicable highlight arguments: font, guibg, guifg. | |
| 4433 | |
| 4434 NOTE: For Motif and Athena the font argument actually | |
| 4435 specifies a fontset at all times, no matter if 'guifontset' is | |
| 4436 empty, and as such it is tied to the current |:language| when | |
| 4437 set. | |
| 4438 | |
| 4439 *hl-Scrollbar* | |
| 4440 Scrollbar Current background and foreground of the main window's | |
| 4441 scrollbars. | |
| 4442 Applicable highlight arguments: guibg, guifg. | |
| 4443 | |
| 4444 *hl-Tooltip* | |
| 4445 Tooltip Current font, background and foreground of the tooltips. | |
| 4446 Applicable highlight arguments: font, guibg, guifg. | |
| 4447 | |
| 4448 NOTE: For Motif and Athena the font argument actually | |
| 4449 specifies a fontset at all times, no matter if 'guifontset' is | |
| 4450 empty, and as such it is tied to the current |:language| when | |
| 4451 set. | |
| 4452 | |
| 4453 ============================================================================== | |
| 4454 13. Linking groups *:hi-link* *:highlight-link* *E412* *E413* | |
| 4455 | |
| 4456 When you want to use the same highlighting for several syntax groups, you | |
| 4457 can do this more easily by linking the groups into one common highlight | |
| 4458 group, and give the color attributes only for that group. | |
| 4459 | |
| 4460 To set a link: | |
| 4461 | |
| 4462 :hi[ghlight][!] [default] link {from-group} {to-group} | |
| 4463 | |
| 4464 To remove a link: | |
| 4465 | |
| 4466 :hi[ghlight][!] [default] link {from-group} NONE | |
| 4467 | |
| 4468 Notes: *E414* | |
| 4469 - If the {from-group} and/or {to-group} doesn't exist, it is created. You | |
| 4470 don't get an error message for a non-existing group. | |
| 4471 - As soon as you use a ":highlight" command for a linked group, the link is | |
| 4472 removed. | |
| 4473 - If there are already highlight settings for the {from-group}, the link is | |
| 4474 not made, unless the '!' is given. For a ":highlight link" command in a | |
| 4475 sourced file, you don't get an error message. This can be used to skip | |
| 4476 links for groups that already have settings. | |
| 4477 | |
| 4478 *:hi-default* *:highlight-default* | |
| 4479 The [default] argument is used for setting the default highlighting for a | |
| 4480 group. If highlighting has already been specified for the group the command | |
| 4481 will be ignored. Also when there is an existing link. | |
| 4482 | |
| 4483 Using [default] is especially useful to overrule the highlighting of a | |
| 4484 specific syntax file. For example, the C syntax file contains: > | |
| 4485 :highlight default link cComment Comment | |
| 4486 If you like Question highlighting for C comments, put this in your vimrc file: > | |
| 4487 :highlight link cComment Question | |
| 4488 Without the "default" in the C syntax file, the highlighting would be | |
| 4489 overruled when the syntax file is loaded. | |
| 4490 | |
| 4491 ============================================================================== | |
| 4492 14. Cleaning up *:syn-clear* *E391* | |
| 4493 | |
| 4494 If you want to clear the syntax stuff for the current buffer, you can use this | |
| 4495 command: > | |
| 4496 :syntax clear | |
| 4497 | |
| 4498 This command should be used when you want to switch off syntax highlighting, | |
| 4499 or when you want to switch to using another syntax. It's normally not needed | |
| 4500 in a syntax file itself, because syntax is cleared by the autocommands that | |
| 4501 load the syntax file. | |
| 4502 The command also deletes the "b:current_syntax" variable, since no syntax is | |
| 4503 loaded after this command. | |
| 4504 | |
| 4505 If you want to disable syntax highlighting for all buffers, you need to remove | |
| 4506 the autocommands that load the syntax files: > | |
| 4507 :syntax off | |
| 4508 | |
| 4509 What this command actually does, is executing the command > | |
| 4510 :source $VIMRUNTIME/syntax/nosyntax.vim | |
| 4511 See the "nosyntax.vim" file for details. Note that for this to work | |
| 4512 $VIMRUNTIME must be valid. See |$VIMRUNTIME|. | |
| 4513 | |
| 4514 To clean up specific syntax groups for the current buffer: > | |
| 4515 :syntax clear {group-name} .. | |
| 4516 This removes all patterns and keywords for {group-name}. | |
| 4517 | |
| 4518 To clean up specific syntax group lists for the current buffer: > | |
| 4519 :syntax clear @{grouplist-name} .. | |
| 4520 This sets {grouplist-name}'s contents to an empty list. | |
| 4521 | |
| 4522 *:syntax-reset* *:syn-reset* | |
| 4523 If you have changed the colors and messed them up, use this command to get the | |
| 4524 defaults back: > | |
| 4525 | |
| 4526 :syntax reset | |
| 4527 | |
| 4528 This doesn't change the colors for the 'highlight' option. | |
| 4529 | |
| 4530 Note that the syntax colors that you set in your vimrc file will also be reset | |
| 4531 back to their Vim default. | |
| 4532 Note that if you are using a color scheme, the colors defined by the color | |
| 4533 scheme for syntax highlighting will be lost. | |
| 4534 | |
| 4535 What this actually does is: > | |
| 4536 | |
| 4537 let g:syntax_cmd = "reset" | |
| 4538 runtime! syntax/syncolor.vim | |
| 4539 | |
| 4540 Note that this uses the 'runtimepath' option. | |
| 4541 | |
| 4542 *syncolor* | |
| 4543 If you want to use different colors for syntax highlighting, you can add a Vim | |
| 4544 script file to set these colors. Put this file in a directory in | |
| 4545 'runtimepath' which comes after $VIMRUNTIME, so that your settings overrule | |
| 4546 the default colors. This way these colors will be used after the ":syntax | |
| 4547 reset" command. | |
| 4548 | |
| 4549 For Unix you can use the file ~/.vim/after/syntax/syncolor.vim. Example: > | |
| 4550 | |
| 4551 if &background == "light" | |
| 4552 highlight comment ctermfg=darkgreen guifg=darkgreen | |
| 4553 else | |
| 4554 highlight comment ctermfg=green guifg=green | |
| 4555 endif | |
| 4556 | |
| 24 | 4557 *E679* |
| 4558 Do make sure this syncolor.vim script does not use a "syntax on", set the | |
| 4559 'background' option or uses a "colorscheme" command, because it results in an | |
| 4560 endless loop. | |
| 4561 | |
| 7 | 4562 Note that when a color scheme is used, there might be some confusion whether |
| 4563 your defined colors are to be used or the colors from the scheme. This | |
| 4564 depends on the color scheme file. See |:colorscheme|. | |
| 4565 | |
| 4566 *syntax_cmd* | |
| 4567 The "syntax_cmd" variable is set to one of these values when the | |
| 4568 syntax/syncolor.vim files are loaded: | |
| 4569 "on" ":syntax on" command. Highlight colors are overruled but | |
| 4570 links are kept | |
| 4571 "enable" ":syntax enable" command. Only define colors for groups that | |
| 4572 don't have highlighting yet. Use ":syntax default". | |
| 4573 "reset" ":syntax reset" command or loading a color scheme. Define all | |
| 4574 the colors. | |
| 4575 "skip" Don't define colors. Used to skip the default settings when a | |
| 4576 syncolor.vim file earlier in 'runtimepath' has already set | |
| 4577 them. | |
| 4578 | |
| 4579 ============================================================================== | |
| 4580 15. Highlighting tags *tag-highlight* | |
| 4581 | |
| 4582 If you want to highlight all the tags in your file, you can use the following | |
| 4583 mappings. | |
| 4584 | |
| 4585 <F11> -- Generate tags.vim file, and highlight tags. | |
| 4586 <F12> -- Just highlight tags based on existing tags.vim file. | |
| 4587 > | |
| 4588 :map <F11> :sp tags<CR>:%s/^\([^ :]*:\)\=\([^ ]*\).*/syntax keyword Tag \2/<CR>:wq! tags.vim<CR>/^<CR><F12> | |
| 4589 :map <F12> :so tags.vim<CR> | |
| 4590 | |
| 4591 WARNING: The longer the tags file, the slower this will be, and the more | |
| 4592 memory Vim will consume. | |
| 4593 | |
| 4594 Only highlighting typedefs, unions and structs can be done too. For this you | |
| 4595 must use Exuberant ctags (found at http://ctags.sf.net). | |
| 4596 | |
| 4597 Put these lines in your Makefile: | |
| 4598 | |
| 4599 # Make a highlight file for types. Requires Exuberant ctags and awk | |
| 4600 types: types.vim | |
| 4601 types.vim: *.[ch] | |
| 1125 | 4602 ctags --c-kinds=gstu -o- *.[ch] |\ |
| 7 | 4603 awk 'BEGIN{printf("syntax keyword Type\t")}\ |
| 4604 {printf("%s ", $$1)}END{print ""}' > $@ | |
| 4605 | |
| 4606 And put these lines in your .vimrc: > | |
| 4607 | |
| 4608 " load the types.vim highlighting file, if it exists | |
| 4609 autocmd BufRead,BufNewFile *.[ch] let fname = expand('<afile>:p:h') . '/types.vim' | |
| 4610 autocmd BufRead,BufNewFile *.[ch] if filereadable(fname) | |
| 4611 autocmd BufRead,BufNewFile *.[ch] exe 'so ' . fname | |
| 4612 autocmd BufRead,BufNewFile *.[ch] endif | |

| 2581 | 4644 17. Color xterms *xterm-color* *color-xterm* |
| 7 | 4645 |
| 4646 Most color xterms have only eight colors. If you don't get colors with the | |
| 4647 default setup, it should work with these lines in your .vimrc: > | |
| 4648 :if &term =~ "xterm" | |
| 4649 : if has("terminfo") | |
| 4650 : set t_Co=8 | |
| 4651 : set t_Sf=<Esc>[3%p1%dm | |
| 4652 : set t_Sb=<Esc>[4%p1%dm | |
| 4653 : else | |
| 4654 : set t_Co=8 | |
| 4655 : set t_Sf=<Esc>[3%dm | |
| 4656 : set t_Sb=<Esc>[4%dm | |
| 4657 : endif | |
| 4658 :endif | |
| 4659 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 4660 | |
| 4661 You might want to change the first "if" to match the name of your terminal, | |
| 4662 e.g. "dtterm" instead of "xterm". | |
| 4663 | |
| 4664 Note: Do these settings BEFORE doing ":syntax on". Otherwise the colors may | |
| 4665 be wrong. | |
| 4666 *xiterm* *rxvt* | |
| 4667 The above settings have been mentioned to work for xiterm and rxvt too. | |
| 4668 But for using 16 colors in an rxvt these should work with terminfo: > | |

| 4672 *colortest.vim* | |
| 4673 To test your color setup, a file has been included in the Vim distribution. | |
| 671 | 4674 To use it, execute this command: > |
| 4675 :runtime syntax/colortest.vim | |
| 7 | 4676 |
| 237 | 4677 Some versions of xterm (and other terminals, like the Linux console) can |
| 7 | 4678 output lighter foreground colors, even though the number of colors is defined |
| 4679 at 8. Therefore Vim sets the "cterm=bold" attribute for light foreground | |
| 4680 colors, when 't_Co' is 8. | |
| 4681 | |
| 4682 *xfree-xterm* | |
| 4683 To get 16 colors or more, get the newest xterm version (which should be | |
| 237 | 4684 included with XFree86 3.3 and later). You can also find the latest version |
| 7 | 4685 at: > |
| 4686 http://invisible-island.net/xterm/xterm.html | |
| 4687 Here is a good way to configure it. This uses 88 colors and enables the | |
| 4688 termcap-query feature, which allows Vim to ask the xterm how many colors it | |
| 4689 supports. > | |
| 4690 ./configure --disable-bold-color --enable-88-color --enable-tcap-query | |
| 4691 If you only get 8 colors, check the xterm compilation settings. | |
| 4692 (Also see |UTF8-xterm| for using this xterm with UTF-8 character encoding). | |
| 4693 | |
| 4694 This xterm should work with these lines in your .vimrc (for 16 colors): > | |
| 4695 :if has("terminfo") | |
| 4696 : set t_Co=16 | |
| 4697 : set t_AB=<Esc>[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{92}%+%;%dm | |
| 4698 : set t_AF=<Esc>[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{82}%+%;%dm | |
| 4699 :else | |
| 4700 : set t_Co=16 | |
| 4701 : set t_Sf=<Esc>[3%dm | |
| 4702 : set t_Sb=<Esc>[4%dm | |
| 4703 :endif | |
| 4704 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 4705 | |
| 4706 Without |+terminfo|, Vim will recognize these settings, and automatically | |
| 4707 translate cterm colors of 8 and above to "<Esc>[9%dm" and "<Esc>[10%dm". | |
| 4708 Colors above 16 are also translated automatically. | |
| 4709 | |
| 4710 For 256 colors this has been reported to work: > | |
| 4711 | |
| 4712 :set t_AB=<Esc>[48;5;%dm | |
| 4713 :set t_AF=<Esc>[38;5;%dm | |
| 4714 | |
| 4715 Or just set the TERM environment variable to "xterm-color" or "xterm-16color" | |
| 4716 and try if that works. | |
| 4717 | |
| 4718 You probably want to use these X resources (in your ~/.Xdefaults file): | |
| 4719 XTerm*color0: #000000 | |
| 4720 XTerm*color1: #c00000 | |
| 4721 XTerm*color2: #008000 | |
| 4722 XTerm*color3: #808000 | |
| 4723 XTerm*color4: #0000c0 | |
| 4724 XTerm*color5: #c000c0 | |
| 4725 XTerm*color6: #008080 | |
| 4726 XTerm*color7: #c0c0c0 | |
| 4727 XTerm*color8: #808080 | |
| 4728 XTerm*color9: #ff6060 | |
| 4729 XTerm*color10: #00ff00 | |
| 4730 XTerm*color11: #ffff00 | |
| 4731 XTerm*color12: #8080ff | |
| 4732 XTerm*color13: #ff40ff | |
| 4733 XTerm*color14: #00ffff | |
| 4734 XTerm*color15: #ffffff | |
| 4735 Xterm*cursorColor: Black | |
| 4736 | |
| 4737 [Note: The cursorColor is required to work around a bug, which changes the | |
| 4738 cursor color to the color of the last drawn text. This has been fixed by a | |
| 1125 | 4739 newer version of xterm, but not everybody is using it yet.] |
| 7 | 4740 |
| 4741 To get these right away, reload the .Xdefaults file to the X Option database | |
| 4742 Manager (you only need to do this when you just changed the .Xdefaults file): > | |
| 4743 xrdb -merge ~/.Xdefaults | |
| 4744 < | |
| 4745 *xterm-blink* *xterm-blinking-cursor* | |
| 4746 To make the cursor blink in an xterm, see tools/blink.c. Or use Thomas | |
| 4747 Dickey's xterm above patchlevel 107 (see above for where to get it), with | |
| 4748 these resources: | |
| 4749 XTerm*cursorBlink: on | |
| 4750 XTerm*cursorOnTime: 400 | |
| 4751 XTerm*cursorOffTime: 250 | |
| 4752 XTerm*cursorColor: White | |
| 4753 | |
| 4754 *hpterm-color* | |
| 1125 | 4755 These settings work (more or less) for an hpterm, which only supports 8 |
| 7 | 4756 foreground colors: > |
| 4757 :if has("terminfo") | |
| 4758 : set t_Co=8 | |
| 4759 : set t_Sf=<Esc>[&v%p1%dS | |
| 4760 : set t_Sb=<Esc>[&v7S | |
| 4761 :else | |
| 4762 : set t_Co=8 | |
| 4763 : set t_Sf=<Esc>[&v%dS | |
| 4764 : set t_Sb=<Esc>[&v7S | |
| 4765 :endif | |
| 4766 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
| 4767 | |
| 4768 *Eterm* *enlightened-terminal* | |
| 4769 These settings have been reported to work for the Enlightened terminal | |
| 4770 emulator, or Eterm. They might work for all xterm-like terminals that use the | |
| 4771 bold attribute to get bright colors. Add an ":if" like above when needed. > | |
| 4772 :set t_Co=16 | |
| 4773 :set t_AF=^[[%?%p1%{8}%<%t3%p1%d%e%p1%{22}%+%d;1%;m | |
| 4774 :set t_AB=^[[%?%p1%{8}%<%t4%p1%d%e%p1%{32}%+%d;1%;m | |
| 4775 < | |
| 4776 *TTpro-telnet* | |
| 4777 These settings should work for TTpro telnet. Tera Term Pro is a freeware / | |
| 4778 open-source program for MS-Windows. > | |
| 4779 set t_Co=16 | |
| 4780 set t_AB=^[[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{32}%+5;%;%dm | |
| 4781 set t_AF=^[[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{22}%+1;%;%dm | |
| 4782 Also make sure TTpro's Setup / Window / Full Color is enabled, and make sure | |
| 4783 that Setup / Font / Enable Bold is NOT enabled. | |
