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. | |

45 Syntax highlighting is not available when the |+syntax| feature has been | |
46 disabled at compile time. | |

48 ============================================================================== | |
49 1. Quick start *:syn-qstart* | |
50 | |
51 *:syn-enable* *:syntax-enable* | |
52 This command switches on syntax highlighting: > | |
53 | |
54 :syntax enable | |
55 | |
56 What this command actually does is to execute the command > | |
57 :source $VIMRUNTIME/syntax/syntax.vim | |
58 | |
59 If the VIM environment variable is not set, Vim will try to find | |
60 the path in another way (see |$VIMRUNTIME|). Usually this works just | |
61 fine. If it doesn't, try setting the VIM environment variable to the | |
62 directory where the Vim stuff is located. For example, if your syntax files | |
18343 | 63 are in the "/usr/vim/vim81/syntax" directory, set $VIMRUNTIME to |
64 "/usr/vim/vim81". You must do this in the shell, before starting Vim. | |

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

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

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

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

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

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

454 :let g:html_whole_filler = 1 | |
455 < | |
456 *TOhtml-performance* *g:html_no_progress* | |
457 Default: 0. | |
458 When 0, display a progress bar in the statusline for each major step in the | |
459 2html.vim conversion process. | |
460 When 1, do not display the progress bar. This offers a minor speed improvement | |
461 but you won't have any idea how much longer the conversion might take; for big | |
462 files it can take a long time! | |
463 Example: > | |
464 | |
465 let g:html_no_progress = 1 | |
466 < | |
467 You can obtain better performance improvements by also instructing Vim to not | |
468 run interactively, so that too much time is not taken to redraw as the script | |
469 moves through the buffer, switches windows, and the like: > | |
470 | |
471 vim -E -s -c "let g:html_no_progress=1" -c "syntax on" -c "set ft=c" -c "runtime syntax/2html.vim" -cwqa myfile.c | |
472 < | |
473 Note that the -s flag prevents loading your .vimrc and any plugins, so you | |
474 need to explicitly source/enable anything that will affect the HTML | |
475 conversion. See |-E| and |-s-ex| for details. It is probably best to create a | |
476 script to replace all the -c commands and use it with the -u flag instead of | |
477 specifying each command separately. | |
478 | |
18639 | 479 *hl-TOhtmlProgress* *TOhtml-progress-color* |
480 When displayed, the progress bar will show colored boxes along the statusline | |
481 as the HTML conversion proceeds. By default, the background color as the | |
482 current "DiffDelete" highlight group is used. If "DiffDelete" and "StatusLine" | |
483 have the same background color, TOhtml will automatically adjust the color to | |
484 differ. If you do not like the automatically selected colors, you can define | |
485 your own highlight colors for the progress bar. Example: > | |
486 | |
487 hi TOhtmlProgress guifg=#c0ffee ctermbg=7 | |
488 < | |
3713 | 489 *g:html_number_lines* |
490 Default: current 'number' setting. | |
491 When 0, buffer text is displayed in the generated HTML without line numbering. | |
492 When 1, a column of line numbers is added to the generated HTML with the same | |
493 highlighting as the line number column in Vim (|hl-LineNr|). | |
494 Force line numbers even if 'number' is not set: > | |
495 :let g:html_number_lines = 1 | |
496 Force to omit the line numbers: > | |
497 :let g:html_number_lines = 0 | |
498 Go back to the default to use 'number' by deleting the variable: > | |
499 :unlet g:html_number_lines | |

3713 | 518 *g:html_use_css* |
519 Default: 1. | |
18639 | 520 When 1, generate valid HTML 5 markup with CSS styling, supported in all modern |
521 browsers and many old browsers. | |
3713 | 522 When 0, generate <font> tags and similar outdated markup. This is not |
523 recommended but it may work better in really old browsers, email clients, | |
524 forum posts, and similar situations where basic CSS support is unavailable. | |
525 Example: > | |
526 :let g:html_use_css = 0 | |
527 < | |
528 *g:html_ignore_conceal* | |
529 Default: 0. | |
530 When 0, concealed text is removed from the HTML and replaced with a character | |
531 from |:syn-cchar| or 'listchars' as appropriate, depending on the current | |
532 value of 'conceallevel'. | |
533 When 1, include all text from the buffer in the generated HTML, even if it is | |
534 |conceal|ed. | |
535 | |
536 Either of the following commands will ensure that all text in the buffer is | |
537 included in the generated HTML (unless it is folded): > | |
538 :let g:html_ignore_conceal = 1 | |
539 :setl conceallevel=0 | |
540 < | |
541 *g:html_ignore_folding* | |
542 Default: 0. | |
543 When 0, text in a closed fold is replaced by the text shown for the fold in | |
544 Vim (|fold-foldtext|). See |g:html_dynamic_folds| if you also want to allow | |
545 the user to expand the fold as in Vim to see the text inside. | |
546 When 1, include all text from the buffer in the generated HTML; whether the | |
547 text is in a fold has no impact at all. |g:html_dynamic_folds| has no effect. | |
548 | |
549 Either of these commands will ensure that all text in the buffer is included | |
550 in the generated HTML (unless it is concealed): > | |
551 zR | |
552 :let g:html_ignore_folding = 1 | |
553 < | |
554 *g:html_dynamic_folds* | |
555 Default: 0. | |
556 When 0, text in a closed fold is not included at all in the generated HTML. | |
557 When 1, generate javascript to open a fold and show the text within, just like | |
558 in Vim. | |
559 | |
560 Setting this variable to 1 causes 2html.vim to always use CSS for styling, | |
561 regardless of what |g:html_use_css| is set to. | |
562 | |
563 This variable is ignored when |g:html_ignore_folding| is set. | |
564 > | |
565 :let g:html_dynamic_folds = 1 | |
566 < | |
567 *g:html_no_foldcolumn* | |
568 Default: 0. | |
569 When 0, if |g:html_dynamic_folds| is 1, generate a column of text similar to | |
570 Vim's foldcolumn (|fold-foldcolumn|) the user can click on to toggle folds | |
571 open or closed. The minimum width of the generated text column is the current | |
572 'foldcolumn' setting. | |
573 When 1, do not generate this column; instead, hovering the mouse cursor over | |
574 folded text will open the fold as if |g:html_hover_unfold| were set. | |
575 > | |
576 :let g:html_no_foldcolumn = 1 | |
577 < | |
578 *TOhtml-uncopyable-text* *g:html_prevent_copy* | |
579 Default: empty string. | |
580 This option prevents certain regions of the generated HTML from being copied, | |
581 when you select all text in document rendered in a browser and copy it. Useful | |
582 for allowing users to copy-paste only the source text even if a fold column or | |
583 line numbers are shown in the generated content. Specify regions to be | |
584 affected in this way as follows: | |
585 f: fold column | |
586 n: line numbers (also within fold text) | |
587 t: fold text | |
588 d: diff filler | |
589 | |
590 Example, to make the fold column and line numbers uncopyable: > | |
591 :let g:html_prevent_copy = "fn" | |
592 < | |
18639 | 593 The method used to prevent copying in the generated page depends on the value |
594 of |g:html_use_input_for_pc|. | |
595 | |
596 *g:html_use_input_for_pc* | |
597 Default: "fallback" | |
598 If |g:html_prevent_copy| is non-empty, then: | |
599 | |
600 When "all", read-only <input> elements are used in place of normal text for | |
601 uncopyable regions. In some browsers, especially older browsers, after | |
602 selecting an entire page and copying the selection, the <input> tags are not | |
603 pasted with the page text. If |g:html_no_invalid| is 0, the <input> tags have | |
604 invalid type; this works in more browsers, but the page will not validate. | |
605 Note: this method does NOT work in recent versions of Chrome and equivalent | |
606 browsers; the <input> tags get pasted with the text. | |
607 | |
608 When "fallback" (default value), the same <input> elements are generated for | |
609 older browsers, but newer browsers (detected by CSS feature query) hide the | |
610 <input> elements and instead use generated content in an ::before pseudoelement | |
611 to display the uncopyable text. This method should work with the largest | |
612 number of browsers, both old and new. | |
613 | |
614 When "none", the <input> elements are not generated at all. Only the | |
615 generated-content method is used. This means that old browsers, notably | |
616 Internet Explorer, will either copy the text intended not to be copyable, or | |
617 the non-copyable text may not appear at all. However, this is the most | |
618 standards-based method, and there will be much less markup. | |
3713 | 619 |
620 *g:html_no_invalid* | |
621 Default: 0. | |
18639 | 622 When 0, if |g:html_prevent_copy| is non-empty and |g:html_use_input_for_pc| is |
623 not "none", an invalid attribute is intentionally inserted into the <input> | |
624 element for the uncopyable areas. This prevents pasting the <input> elements | |
625 in some applications. Specifically, some versions of Microsoft Word will not | |
626 paste the <input> elements if they contain this invalid attribute. When 1, no | |
627 invalid markup is inserted, and the generated page should validate. However, | |
628 <input> elements may be pasted into some applications and can be difficult to | |
629 remove afterward. | |
3713 | 630 |
631 *g:html_hover_unfold* | |
632 Default: 0. | |
633 When 0, the only way to open a fold generated by 2html.vim with | |
634 |g:html_dynamic_folds| set, is to click on the generated fold column. | |
635 When 1, use CSS 2.0 to allow the user to open a fold by moving the mouse | |
636 cursor over the displayed fold text. This is useful to allow users with | |
637 disabled javascript to view the folded text. | |
638 | |
639 Note that old browsers (notably Internet Explorer 6) will not support this | |
640 feature. Browser-specific markup for IE6 is included to fall back to the | |
641 normal CSS1 styling so that the folds show up correctly for this browser, but | |
642 they will not be openable without a foldcolumn. | |

3713 | 665 *TOhtml-wrap-text* *g:html_pre_wrap* |
666 Default: current 'wrap' setting. | |
667 When 0, if |g:html_no_pre| is 0 or unset, the text in the generated HTML does | |
668 not wrap at the edge of the browser window. | |
669 When 1, if |g:html_use_css| is 1, the CSS 2.0 "white-space:pre-wrap" value is | |
670 used, causing the text to wrap at whitespace at the edge of the browser | |
671 window. | |
672 Explicitly enable text wrapping: > | |
673 :let g:html_pre_wrap = 1 | |
674 Explicitly disable wrapping: > | |
675 :let g:html_pre_wrap = 0 | |
676 Go back to default, determine wrapping from 'wrap' setting: > | |
677 :unlet g:html_pre_wrap | |
678 < | |
679 *g:html_no_pre* | |
680 Default: 0. | |
681 When 0, buffer text in the generated HTML is surrounded by <pre>...</pre> | |
682 tags. Series of whitespace is shown as in Vim without special markup, and tab | |
683 characters can be included literally (see |g:html_expand_tabs|). | |
684 When 1 (not recommended), the <pre> tags are omitted, and a plain <div> is | |
685 used instead. Whitespace is replaced by a series of character | |
686 references, and <br> is used to end each line. This is another way to allow | |
687 text in the generated HTML is wrap (see |g:html_pre_wrap|) which also works in | |
688 old browsers, but may cause noticeable differences between Vim's display and | |
689 the rendered page generated by 2html.vim. | |
690 > | |
691 :let g:html_no_pre = 1 | |
692 < | |
693 *g:html_expand_tabs* | |
15033 | 694 Default: 0 if 'tabstop' is 8, 'expandtab' is 0, 'vartabstop' is not in use, |
695 and no fold column or line numbers occur in the generated HTML; | |
696 1 otherwise. | |
697 When 1, <Tab> characters in the buffer text are replaced with an appropriate | |
3713 | 698 number of space characters, or references if |g:html_no_pre| is 1. |
15033 | 699 When 0, if |g:html_no_pre| is 0 or unset, <Tab> characters in the buffer text |
3713 | 700 are included as-is in the generated HTML. This is useful for when you want to |
701 allow copy and paste from a browser without losing the actual whitespace in | |
702 the source document. Note that this can easily break text alignment and | |
703 indentation in the HTML, unless set by default. | |
704 | |
705 Force |2html.vim| to keep <Tab> characters: > | |
706 :let g:html_expand_tabs = 0 | |
707 < | |
708 Force tabs to be expanded: > | |
709 :let g:html_expand_tabs = 1 | |
710 < | |
711 *TOhtml-encoding-detect* *TOhtml-encoding* | |
712 It is highly recommended to set your desired encoding with | |
713 |g:html_use_encoding| for any content which will be placed on a web server. | |
714 | |
715 If you do not specify an encoding, |2html.vim| uses the preferred IANA name | |
716 for the current value of 'fileencoding' if set, or 'encoding' if not. | |
717 'encoding' is always used for certain 'buftype' values. 'fileencoding' will be | |
718 set to match the chosen document encoding. | |
719 | |
720 Automatic detection works for the encodings mentioned specifically by name in | |
721 |encoding-names|, but TOhtml will only automatically use those encodings with | |
722 wide browser support. However, you can override this to support specific | |
723 encodings that may not be automatically detected by default (see options | |
724 below). See http://www.iana.org/assignments/character-sets for the IANA names. | |
725 | |
726 Note, by default all Unicode encodings are converted to UTF-8 with no BOM in | |
727 the generated HTML, as recommended by W3C: | |
728 | |
729 http://www.w3.org/International/questions/qa-choosing-encodings | |
730 http://www.w3.org/International/questions/qa-byte-order-mark | |
731 | |
732 *g:html_use_encoding* | |
733 Default: none, uses IANA name for current 'fileencoding' as above. | |
734 To overrule all automatic charset detection, set g:html_use_encoding to the | |
735 name of the charset to be used. It is recommended to set this variable to | |
736 something widely supported, like UTF-8, for anything you will be hosting on a | |
737 webserver: > | |
738 :let g:html_use_encoding = "UTF-8" | |
739 You can also use this option to omit the line that specifies the charset | |
740 entirely, by setting g:html_use_encoding to an empty string (NOT recommended): > | |
741 :let g:html_use_encoding = "" | |
742 To go back to the automatic mechanism, delete the |g:html_use_encoding| | |
743 variable: > | |
744 :unlet g:html_use_encoding | |
745 < | |
746 *g:html_encoding_override* | |
747 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
748 mentioned by name at |encoding-names|. | |
749 This option allows |2html.vim| to detect the correct 'fileencoding' when you | |
750 specify an encoding with |g:html_use_encoding| which is not in the default | |
751 list of conversions. | |
752 | |
753 This is a dictionary of charset-encoding pairs that will replace existing | |
754 pairs automatically detected by TOhtml, or supplement with new pairs. | |
755 | |
756 Detect the HTML charset "windows-1252" as the encoding "8bit-cp1252": > | |
757 :let g:html_encoding_override = {'windows-1252': '8bit-cp1252'} | |
758 < | |
759 *g:html_charset_override* | |
760 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
761 mentioned by name at |encoding-names| and which have wide | |
762 browser support. | |
763 This option allows |2html.vim| to detect the HTML charset for any | |
764 'fileencoding' or 'encoding' which is not detected automatically. You can also | |
765 use it to override specific existing encoding-charset pairs. For example, | |
766 TOhtml will by default use UTF-8 for all Unicode/UCS encodings. To use UTF-16 | |
767 and UTF-32 instead, use: > | |
768 :let g:html_charset_override = {'ucs-4': 'UTF-32', 'utf-16': 'UTF-16'} | |
769 | |
770 Note that documents encoded in either UTF-32 or UTF-16 have known | |
771 compatibility problems with some major browsers. | |

855 Files matching "*.i" could be Progress or Assembly. If the automatic detection | |
856 doesn't work for you, or you don't edit Progress at all, use this in your | |
857 startup vimrc: > | |
858 :let filetype_i = "asm" | |
859 Replace "asm" with the type of assembly you use. | |
860 | |
861 There are many types of assembly languages that all use the same file name | |
862 extensions. Therefore you will have to select the type yourself, or add a | |
863 line in the assembly file that Vim will recognize. Currently these syntax | |
864 files are included: | |
865 asm GNU assembly (the default) | |
866 asm68k Motorola 680x0 assembly | |
867 asmh8300 Hitachi H-8300 version of GNU assembly | |
868 ia64 Intel Itanium 64 | |
869 fasm Flat assembly (http://flatassembler.net) | |
870 masm Microsoft assembly (probably works for any 80x86) | |
871 nasm Netwide assembly | |
872 tasm Turbo Assembly (with opcodes 80x86 up to Pentium, and | |
873 MMX) | |
874 pic PIC assembly (currently for PIC16F84) | |
875 | |
876 The most flexible is to add a line in your assembly file containing: > | |

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

7 | 913 |
914 *.asp and *.asa files could be either Perl or Visual Basic script. Since it's | |
915 hard to detect this you can set two global variables to tell Vim what you are | |
916 using. For Perl script use: > | |
917 :let g:filetype_asa = "aspperl" | |
918 :let g:filetype_asp = "aspperl" | |
919 For Visual Basic use: > | |
920 :let g:filetype_asa = "aspvbs" | |

935 | |
936 Syntax folding can be enabled at various levels through the variables | |
937 mentioned below (Set those in your |.vimrc|). The more complex folding on | |
938 source blocks and SQL can be CPU intensive. | |
939 | |
940 To allow any folding and enable folding at function level use: > | |
941 let baan_fold=1 | |
942 Folding can be enabled at source block level as if, while, for ,... The | |
943 indentation preceding the begin/end keywords has to match (spaces are not | |
944 considered equal to a tab). > | |
945 let baan_fold_block=1 | |
946 Folding can be enabled for embedded SQL blocks as SELECT, SELECTDO, | |
856 | 947 SELECTEMPTY, ... The indentation preceding the begin/end keywords has to |
844 | 948 match (spaces are not considered equal to a tab). > |
949 let baan_fold_sql=1 | |
856 | 950 Note: Block folding can result in many small folds. It is suggested to |:set| |
844 | 951 the options 'foldminlines' and 'foldnestmax' in |.vimrc| or use |:setlocal| in |
952 .../after/syntax/baan.vim (see |after-directory|). Eg: > | |
953 set foldminlines=5 | |
954 set foldnestmax=6 | |

501 | 957 BASIC *basic.vim* *vb.vim* *ft-basic-syntax* *ft-vb-syntax* |
7 | 958 |
959 Both Visual Basic and "normal" basic use the extension ".bas". To detect | |
960 which one should be used, Vim checks for the string "VB_Name" in the first | |
961 five lines of the file. If it is not found, filetype will be "basic", | |
962 otherwise "vb". Files with the ".frm" extension will always be seen as Visual | |
963 Basic. | |

501 | 966 C *c.vim* *ft-c-syntax* |
7 | 967 |
968 A few things in C highlighting are optional. To enable them assign any value | |
969 to the respective variable. Example: > | |
1624 | 970 :let c_comment_strings = 1 |
7 | 971 To disable them use ":unlet". Example: > |
972 :unlet c_comment_strings | |
973 | |
14999 | 974 An alternative is to switch to the C++ highlighting: > |
975 :set filetype=cpp | |

1000 *c_no_bsd* don't highlight BSD specific types |
7 | 1001 |
36 | 1002 When 'foldmethod' is set to "syntax" then /* */ comments and { } blocks will |
1003 become a fold. If you don't want comments to become a fold use: > | |
1004 :let c_no_comment_fold = 1 | |
842 | 1005 "#if 0" blocks are also folded, unless: > |
1006 :let c_no_if0_fold = 1 | |
36 | 1007 |
7 | 1008 If you notice highlighting errors while scrolling backwards, which are fixed |
1009 when redrawing with CTRL-L, try setting the "c_minlines" internal variable | |
1010 to a larger number: > | |
1011 :let c_minlines = 100 | |
1012 This will make the syntax synchronization start 100 lines before the first | |
1013 displayed line. The default value is 50 (15 when c_no_if0 is set). The | |
1014 disadvantage of using a larger number is that redrawing can become slow. | |
1015 | |
1016 When using the "#if 0" / "#endif" comment highlighting, notice that this only | |
1017 works when the "#if 0" is within "c_minlines" from the top of the window. If | |
1018 you have a long "#if 0" construct it will not be highlighted correctly. | |
1019 | |
1020 To match extra items in comments, use the cCommentGroup cluster. | |
1021 Example: > | |
1022 :au Syntax c call MyCadd() | |
1023 :function MyCadd() | |
1024 : syn keyword cMyItem contained Ni | |
1025 : syn cluster cCommentGroup add=cMyItem | |
1026 : hi link cMyItem Title | |
1027 :endfun | |
1028 | |
1029 ANSI constants will be highlighted with the "cConstant" group. This includes | |
1030 "NULL", "SIG_IGN" and others. But not "TRUE", for example, because this is | |
1031 not in the ANSI standard. If you find this confusing, remove the cConstant | |
1032 highlighting: > | |
1033 :hi link cConstant NONE | |
1034 | |
1035 If you see '{' and '}' highlighted as an error where they are OK, reset the | |
1036 highlighting for cErrInParen and cErrInBracket. | |
1037 | |
1038 If you want to use folding in your C files, you can add these lines in a file | |

1046 C/C++ interpreter. Ch has similar syntax highlighting to C and builds upon | |
1047 the C syntax file. See |c.vim| for all the settings that are available for C. | |
1048 | |
1049 By setting a variable you can tell Vim to use Ch syntax for *.h files, instead | |
1050 of C or C++: > | |
1051 :let ch_syntax_for_h = 1 | |
1052 | |
7 | 1053 |
501 | 1054 CHILL *chill.vim* *ft-chill-syntax* |
7 | 1055 |
1056 Chill syntax highlighting is similar to C. See |c.vim| for all the settings | |
1057 that are available. Additionally there is: | |
1058 | |
1059 chill_space_errors like c_space_errors | |
1060 chill_comment_string like c_comment_strings | |
1061 chill_minlines like c_minlines | |
1062 | |
1063 | |
501 | 1064 CHANGELOG *changelog.vim* *ft-changelog-syntax* |
7 | 1065 |
1066 ChangeLog supports highlighting spaces at the start of a line. | |
1067 If you do not like this, add following line to your .vimrc: > | |
1068 let g:changelog_spacing_errors = 0 | |
1069 This works the next time you edit a changelog file. You can also use | |
1070 "b:changelog_spacing_errors" to set this per buffer (before loading the syntax | |
1071 file). | |
1072 | |
1073 You can change the highlighting used, e.g., to flag the spaces as an error: > | |
1074 :hi link ChangelogError Error | |
1075 Or to avoid the highlighting: > | |
1076 :hi link ChangelogError NONE | |
1077 This works immediately. | |

5763 | 1097 Setting *g:clojure_fold* enables folding Clojure code via the syntax engine. |
1098 Any list, vector, or map that extends over more than one line can be folded | |
1099 using the standard Vim |fold-commands|. | |
1100 | |
1101 Please note that this option does not work with scripts that redefine the | |
1102 bracket syntax regions, such as rainbow-parentheses plugins. | |

1112 COBOL highlighting has different needs for legacy code than it does for fresh | |
1113 development. This is due to differences in what is being done (maintenance | |
1114 versus development) and other factors. To enable legacy code highlighting, | |
1115 add this line to your .vimrc: > | |
1116 :let cobol_legacy_code = 1 | |
1117 To disable it again, use this: > | |

501 | 1140 CSH *csh.vim* *ft-csh-syntax* |
7 | 1141 |
1142 This covers the shell named "csh". Note that on some systems tcsh is actually | |
1143 used. | |
1144 | |
1145 Detecting whether a file is csh or tcsh is notoriously hard. Some systems | |
1146 symlink /bin/csh to /bin/tcsh, making it almost impossible to distinguish | |
1147 between csh and tcsh. In case VIM guesses wrong you can set the | |
2965 | 1148 "filetype_csh" variable. For using csh: *g:filetype_csh* |
1149 > | |
1150 :let g:filetype_csh = "csh" | |
7 | 1151 |
1152 For using tcsh: > | |
1153 | |
2965 | 1154 :let g:filetype_csh = "tcsh" |
7 | 1155 |
1156 Any script with a tcsh extension or a standard tcsh filename (.tcshrc, | |
1157 tcsh.tcshrc, tcsh.login) will have filetype tcsh. All other tcsh/csh scripts | |

1160 variable. | |
1161 | |
1162 | |
501 | 1163 CYNLIB *cynlib.vim* *ft-cynlib-syntax* |
7 | 1164 |
1165 Cynlib files are C++ files that use the Cynlib class library to enable | |
237 | 1166 hardware modelling and simulation using C++. Typically Cynlib files have a .cc |
7 | 1167 or a .cpp extension, which makes it very difficult to distinguish them from a |
237 | 1168 normal C++ file. Thus, to enable Cynlib highlighting for .cc files, add this |
7 | 1169 line to your .vimrc file: > |
1170 | |
1171 :let cynlib_cyntax_for_cc=1 | |
1172 | |
1173 Similarly for cpp files (this extension is only usually used in Windows) > | |
1174 | |
1175 :let cynlib_cyntax_for_cpp=1 | |
1176 | |
1177 To disable these again, use this: > | |

1179 :unlet cynlib_cyntax_for_cc | |
1180 :unlet cynlib_cyntax_for_cpp | |

1182 | |
501 | 1183 CWEB *cweb.vim* *ft-cweb-syntax* |
7 | 1184 |
1185 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
1186 doesn't work for you, or you don't edit Progress at all, use this in your | |
1187 startup vimrc: > | |
1188 :let filetype_w = "cweb" | |
1189 | |
1190 | |
18456 | 1191 DART *dart.vim* *ft-dart-syntax* |
1192 | |
1193 Dart is an object-oriented, typed, class defined, garbage collected language | |
1194 used for developing mobile, desktop, web, and back-end applications. Dart uses | |
1195 a C-like syntax derived from C, Java, and JavaScript, with features adopted | |
1196 from Smalltalk, Python, Ruby, and others. | |
1197 | |
1198 More information about the language and its development environment at the | |
1199 official Dart language website at https://dart.dev | |
1200 | |
1201 dart.vim syntax detects and highlights Dart statements, reserved words, | |
1202 type declarations, storage classes, conditionals, loops, interpolated values, | |
1203 and comments. There is no support idioms from Flutter or any other Dart | |
1204 framework. | |

501 | 1232 DIRCOLORS *dircolors.vim* *ft-dircolors-syntax* |
7 | 1233 |
1234 The dircolors utility highlighting definition has one option. It exists to | |
1235 provide compatibility with the Slackware GNU/Linux distributions version of | |
1236 the command. It adds a few keywords that are generally ignored by most | |
1237 versions. On Slackware systems, however, the utility accepts the keywords and | |
1238 uses them for processing. To enable the Slackware keywords add the following | |
1239 line to your startup file: > | |
1240 let dircolors_is_slackware = 1 | |
1241 | |
1242 | |
501 | 1243 DOCBOOK *docbk.vim* *ft-docbk-syntax* *docbook* |
2662 | 1244 DOCBOOK XML *docbkxml.vim* *ft-docbkxml-syntax* |
1245 DOCBOOK SGML *docbksgml.vim* *ft-docbksgml-syntax* | |
7 | 1246 |
1247 There are two types of DocBook files: SGML and XML. To specify what type you | |
1248 are using the "b:docbk_type" variable should be set. Vim does this for you | |
1249 automatically if it can recognize the type. When Vim can't guess it the type | |
1250 defaults to XML. | |
1251 You can set the type manually: > | |
1252 :let docbk_type = "sgml" | |
1253 or: > | |
1254 :let docbk_type = "xml" | |
1255 You need to do this before loading the syntax file, which is complicated. | |
1256 Simpler is setting the filetype to "docbkxml" or "docbksgml": > | |
1257 :set filetype=docbksgml | |
1258 or: > | |
1259 :set filetype=docbkxml | |
1260 | |
3967 | 1261 You can specify the DocBook version: > |
1262 :let docbk_ver = 3 | |
1263 When not set 4 is used. | |
1264 | |
7 | 1265 |
501 | 1266 DOSBATCH *dosbatch.vim* *ft-dosbatch-syntax* |
7 | 1267 |
1268 There is one option with highlighting DOS batch files. This covers new | |
1269 extensions to the Command Interpreter introduced with Windows 2000 and | |
1270 is controlled by the variable dosbatch_cmdextversion. For Windows NT | |
1271 this should have the value 1, and for Windows 2000 it should be 2. | |
1272 Select the version you want with the following line: > | |
1273 | |
15 | 1274 :let dosbatch_cmdextversion = 1 |
7 | 1275 |
1276 If this variable is not defined it defaults to a value of 2 to support | |
1277 Windows 2000. | |
1278 | |
15 | 1279 A second option covers whether *.btm files should be detected as type |
237 | 1280 "dosbatch" (MS-DOS batch files) or type "btm" (4DOS batch files). The latter |
1281 is used by default. You may select the former with the following line: > | |
15 | 1282 |
1283 :let g:dosbatch_syntax_for_btm = 1 | |
1284 | |
1285 If this variable is undefined or zero, btm syntax is selected. | |
1286 | |
1287 | |
832 | 1288 DOXYGEN *doxygen.vim* *doxygen-syntax* |
1289 | |
1290 Doxygen generates code documentation using a special documentation format | |
1698 | 1291 (similar to Javadoc). This syntax script adds doxygen highlighting to c, cpp, |
1292 idl and php files, and should also work with java. | |
832 | 1293 |
1224 | 1294 There are a few of ways to turn on doxygen formatting. It can be done |
1295 explicitly or in a modeline by appending '.doxygen' to the syntax of the file. | |
1296 Example: > | |
832 | 1297 :set syntax=c.doxygen |
1298 or > | |
1299 // vim:syntax=c.doxygen | |
1300 | |
3356 | 1301 It can also be done automatically for C, C++, C#, IDL and PHP files by setting |
1302 the global or buffer-local variable load_doxygen_syntax. This is done by | |
1303 adding the following to your .vimrc. > | |
832 | 1304 :let g:load_doxygen_syntax=1 |

|
1306 There are a couple of variables that have an effect on syntax highlighting, and |
832 | 1307 are to do with non-standard highlighting options. |
1308 | |
1309 Variable Default Effect ~ | |
1310 g:doxygen_enhanced_color | |
1311 g:doxygen_enhanced_colour 0 Use non-standard highlighting for | |
1312 doxygen comments. | |
1313 | |
1314 doxygen_my_rendering 0 Disable rendering of HTML bold, italic | |
1315 and html_my_rendering underline. | |
1316 | |
1317 doxygen_javadoc_autobrief 1 Set to 0 to disable javadoc autobrief | |
1318 colour highlighting. | |
1319 | |
1320 doxygen_end_punctuation '[.]' Set to regexp match for the ending | |
856 | 1321 punctuation of brief |
832 | 1322 |
14637 | 1323 There are also some highlight groups worth mentioning as they can be useful in |
832 | 1324 configuration. |
1325 | |
1326 Highlight Effect ~ | |
1327 doxygenErrorComment The colour of an end-comment when missing | |
1328 punctuation in a code, verbatim or dot section | |
1329 doxygenLinkError The colour of an end-comment when missing the | |
1330 \endlink from a \link section. | |
1331 | |
7 | 1332 |
501 | 1333 DTD *dtd.vim* *ft-dtd-syntax* |
7 | 1334 |
237 | 1335 The DTD syntax highlighting is case sensitive by default. To disable |
7 | 1336 case-sensitive highlighting, add the following line to your startup file: > |
1337 | |
1338 :let dtd_ignore_case=1 | |
1339 | |
237 | 1340 The DTD syntax file will highlight unknown tags as errors. If |
7 | 1341 this is annoying, it can be turned off by setting: > |
1342 | |
1343 :let dtd_no_tag_errors=1 | |
1344 | |
1345 before sourcing the dtd.vim syntax file. | |
1346 Parameter entity names are highlighted in the definition using the | |
1347 'Type' highlighting group and 'Comment' for punctuation and '%'. | |
1348 Parameter entity instances are highlighted using the 'Constant' | |
1349 highlighting group and the 'Type' highlighting group for the | |
237 | 1350 delimiters % and ;. This can be turned off by setting: > |
7 | 1351 |
1352 :let dtd_no_param_entities=1 | |
1353 | |
1354 The DTD syntax file is also included by xml.vim to highlight included dtd's. | |
1355 | |
1356 | |
501 | 1357 EIFFEL *eiffel.vim* *ft-eiffel-syntax* |
7 | 1358 |
1359 While Eiffel is not case-sensitive, its style guidelines are, and the | |
237 | 1360 syntax highlighting file encourages their use. This also allows to |
1361 highlight class names differently. If you want to disable case-sensitive | |
7 | 1362 highlighting, add the following line to your startup file: > |
1363 | |
1364 :let eiffel_ignore_case=1 | |
1365 | |
1366 Case still matters for class names and TODO marks in comments. | |
1367 | |
1368 Conversely, for even stricter checks, add one of the following lines: > | |
1369 | |
1370 :let eiffel_strict=1 | |
1371 :let eiffel_pedantic=1 | |
1372 | |
1373 Setting eiffel_strict will only catch improper capitalization for the | |
1374 five predefined words "Current", "Void", "Result", "Precursor", and | |
1375 "NONE", to warn against their accidental use as feature or class names. | |
1376 | |
1377 Setting eiffel_pedantic will enforce adherence to the Eiffel style | |
1378 guidelines fairly rigorously (like arbitrary mixes of upper- and | |
1379 lowercase letters as well as outdated ways to capitalize keywords). | |
1380 | |
1381 If you want to use the lower-case version of "Current", "Void", | |
1382 "Result", and "Precursor", you can use > | |
1383 | |
1384 :let eiffel_lower_case_predef=1 | |
1385 | |
1386 instead of completely turning case-sensitive highlighting off. | |
1387 | |
1388 Support for ISE's proposed new creation syntax that is already | |
1389 experimentally handled by some compilers can be enabled by: > | |
1390 | |
1391 :let eiffel_ise=1 | |
1392 | |
237 | 1393 Finally, some vendors support hexadecimal constants. To handle them, add > |
7 | 1394 |
1395 :let eiffel_hex_constants=1 | |
1396 | |
1397 to your startup file. | |
1398 | |
1399 | |
5697 | 1400 EUPHORIA *euphoria3.vim* *euphoria4.vim* *ft-euphoria-syntax* |
1401 | |
1402 Two syntax highlighting files exists for Euphoria. One for Euphoria | |
1403 version 3.1.1, which is the default syntax highlighting file, and one for | |
1404 Euphoria version 4.0.5 or later. | |
1405 | |
1406 Euphoria version 3.1.1 (http://www.rapideuphoria.com/) is still necessary | |
1407 for developing applications for the DOS platform, which Euphoria version 4 | |
1408 (http://www.openeuphoria.org/) does not support. | |
1409 | |
1410 The following file extensions are auto-detected as Euphoria file type: | |
1411 | |
1412 *.e, *.eu, *.ew, *.ex, *.exu, *.exw | |
1413 *.E, *.EU, *.EW, *.EX, *.EXU, *.EXW | |
1414 | |
1415 To select syntax highlighting file for Euphoria, as well as for | |
1416 auto-detecting the *.e and *.E file extensions as Euphoria file type, | |
1417 add the following line to your startup file: > | |
1418 | |
1419 :let filetype_euphoria="euphoria3" | |
1420 | |
1421 or | |

857 | 1441 FLEXWIKI *flexwiki.vim* *ft-flexwiki-syntax* |
1442 | |
1443 FlexWiki is an ASP.NET-based wiki package available at http://www.flexwiki.com | |
2826 | 1444 NOTE: this site currently doesn't work, on Wikipedia is mentioned that |
1445 development stopped in 2009. | |
857 | 1446 |
1447 Syntax highlighting is available for the most common elements of FlexWiki | |
1448 syntax. The associated ftplugin script sets some buffer-local options to make | |
1449 editing FlexWiki pages more convenient. FlexWiki considers a newline as the | |
1450 start of a new paragraph, so the ftplugin sets 'tw'=0 (unlimited line length), | |
1451 'wrap' (wrap long lines instead of using horizontal scrolling), 'linebreak' | |
1452 (to wrap at a character in 'breakat' instead of at the last char on screen), | |
1453 and so on. It also includes some keymaps that are disabled by default. | |
1454 | |
1455 If you want to enable the keymaps that make "j" and "k" and the cursor keys | |
1456 move up and down by display lines, add this to your .vimrc: > | |
1457 :let flexwiki_maps = 1 | |
1458 | |
1459 | |
501 | 1460 FORM *form.vim* *ft-form-syntax* |
7 | 1461 |
1462 The coloring scheme for syntax elements in the FORM file uses the default | |
1463 modes Conditional, Number, Statement, Comment, PreProc, Type, and String, | |
1275 | 1464 following the language specifications in 'Symbolic Manipulation with FORM' by |
7 | 1465 J.A.M. Vermaseren, CAN, Netherlands, 1991. |
1466 | |
1467 If you want include your own changes to the default colors, you have to | |
1468 redefine the following syntax groups: | |
1469 | |
1470 - formConditional | |
1471 - formNumber | |
1472 - formStatement | |
1473 - formHeaderStatement | |
1474 - formComment | |
1475 - formPreProc | |
1476 - formDirective | |
1477 - formType | |
1478 - formString | |
1479 | |
1480 Note that the form.vim syntax file implements FORM preprocessor commands and | |
1481 directives per default in the same syntax group. | |
1482 | |
1483 A predefined enhanced color mode for FORM is available to distinguish between | |
237 | 1484 header statements and statements in the body of a FORM program. To activate |
7 | 1485 this mode define the following variable in your vimrc file > |
1486 | |
1487 :let form_enhanced_color=1 | |
1488 | |
1489 The enhanced mode also takes advantage of additional color features for a dark | |
237 | 1490 gvim display. Here, statements are colored LightYellow instead of Yellow, and |
7 | 1491 conditionals are LightBlue for better distinction. |
1492 | |
1493 | |
501 | 1494 FORTRAN *fortran.vim* *ft-fortran-syntax* |
7 | 1495 |
1496 Default highlighting and dialect ~ | |
3256 | 1497 Highlighting appropriate for Fortran 2008 is used by default. This choice |
4992 | 1498 should be appropriate for most users most of the time because Fortran 2008 is |
1499 almost a superset of previous versions (Fortran 2003, 95, 90, and 77). | |
7 | 1500 |
1501 Fortran source code form ~ | |
3281 | 1502 Fortran code can be in either fixed or free source form. Note that the |
7 | 1503 syntax highlighting will not be correct if the form is incorrectly set. |
1504 | |
1505 When you create a new fortran file, the syntax script assumes fixed source | |
237 | 1506 form. If you always use free source form, then > |
7 | 1507 :let fortran_free_source=1 |
237 | 1508 in your .vimrc prior to the :syntax on command. If you always use fixed source |
7 | 1509 form, then > |
1510 :let fortran_fixed_source=1 | |
1511 in your .vimrc prior to the :syntax on command. | |

1535 Tabs in fortran files ~ | |
237 | 1536 Tabs are not recognized by the Fortran standards. Tabs are not a good idea in |
7 | 1537 fixed format fortran source code which requires fixed column boundaries. |
237 | 1538 Therefore, tabs are marked as errors. Nevertheless, some programmers like |
1539 using tabs. If your fortran files contain tabs, then you should set the | |
7 | 1540 variable fortran_have_tabs in your .vimrc with a command such as > |
1541 :let fortran_have_tabs=1 | |
237 | 1542 placed prior to the :syntax on command. Unfortunately, the use of tabs will |
7 | 1543 mean that the syntax file will not be able to detect incorrect margins. |
1544 | |
1545 Syntax folding of fortran files ~ | |
1546 If you wish to use foldmethod=syntax, then you must first set the variable | |
1547 fortran_fold with a command such as > | |
1548 :let fortran_fold=1 | |
1549 to instruct the syntax script to define fold regions for program units, that | |
1550 is main programs starting with a program statement, subroutines, function | |
237 | 1551 subprograms, block data subprograms, interface blocks, and modules. If you |
7 | 1552 also set the variable fortran_fold_conditionals with a command such as > |
1553 :let fortran_fold_conditionals=1 | |
1554 then fold regions will also be defined for do loops, if blocks, and select | |
237 | 1555 case constructs. If you also set the variable |
7 | 1556 fortran_fold_multilinecomments with a command such as > |
1557 :let fortran_fold_multilinecomments=1 | |
1558 then fold regions will also be defined for three or more consecutive comment | |
237 | 1559 lines. Note that defining fold regions can be slow for large files. |
7 | 1560 |
1561 If fortran_fold, and possibly fortran_fold_conditionals and/or | |
1562 fortran_fold_multilinecomments, have been set, then vim will fold your file if | |
237 | 1563 you set foldmethod=syntax. Comments or blank lines placed between two program |
7 | 1564 units are not folded because they are seen as not belonging to any program |
1565 unit. | |
1566 | |
1567 More precise fortran syntax ~ | |
1568 If you set the variable fortran_more_precise with a command such as > | |
1569 :let fortran_more_precise=1 | |
237 | 1570 then the syntax coloring will be more precise but slower. In particular, |
7 | 1571 statement labels used in do, goto and arithmetic if statements will be |
1572 recognized, as will construct names at the end of a do, if, select or forall | |
1573 construct. | |
1574 | |
1575 Non-default fortran dialects ~ | |
3281 | 1576 The syntax script supports two Fortran dialects: f08 and F. You will probably |
1577 find the default highlighting (f08) satisfactory. A few legacy constructs | |
1578 deleted or declared obsolescent in the 2008 standard are highlighted as todo | |
1579 items. | |
1580 | |
1581 If you use F, the advantage of setting the dialect appropriately is that | |
1582 other legacy features excluded from F will be highlighted as todo items and | |
4992 | 1583 that free source form will be assumed. |
3281 | 1584 |
1585 The dialect can be selected in various ways. If all your fortran files use | |
1586 the same dialect, set the global variable fortran_dialect in your .vimrc prior | |
1587 to your syntax on statement. The case-sensitive, permissible values of | |
1588 fortran_dialect are "f08" or "F". Invalid values of fortran_dialect are | |
1589 ignored. | |
1590 | |
1591 If the dialect depends upon the file extension, then it is most convenient to | |
1592 set a buffer-local variable in a ftplugin file. For more information on | |
1593 ftplugin files, see |ftplugin|. For example, if all your fortran files with | |
1594 an .f90 extension are written in the F subset, your ftplugin file should | |
1595 contain the code > | |
7 | 1596 let s:extfname = expand("%:e") |
1597 if s:extfname ==? "f90" | |
3281 | 1598 let b:fortran_dialect="F" |
7 | 1599 else |
3281 | 1600 unlet! b:fortran_dialect |
7 | 1601 endif |
1602 Note that this will work only if the "filetype plugin indent on" command | |
1603 precedes the "syntax on" command in your .vimrc file. | |
1604 | |
1605 Finer control is necessary if the file extension does not uniquely identify | |
3281 | 1606 the dialect. You can override the default dialect, on a file-by-file basis, |
1607 by including a comment with the directive "fortran_dialect=xx" (where xx=F or | |
1608 f08) in one of the first three lines in your file. For example, your older .f | |
1609 files may be legacy code but your newer ones may be F codes, and you would | |
1610 identify the latter by including in the first three lines of those files a | |
1611 Fortran comment of the form > | |
7 | 1612 ! fortran_dialect=F |
3281 | 1613 |
1614 For previous versions of the syntax, you may have set fortran_dialect to the | |
1615 now-obsolete values "f77", "f90", "f95", or "elf". Such settings will be | |
1616 silently handled as "f08". Users of "elf" may wish to experiment with "F" | |
4992 | 1617 instead. |
3281 | 1618 |
1619 The syntax/fortran.vim script contains embedded comments that tell you how to | |
1620 comment and/or uncomment some lines to (a) activate recognition of some | |
1621 non-standard, vendor-supplied intrinsics and (b) to prevent features deleted | |
1622 or declared obsolescent in the 2008 standard from being highlighted as todo | |
4992 | 1623 items. |
7 | 1624 |
1625 Limitations ~ | |
237 | 1626 Parenthesis checking does not catch too few closing parentheses. Hollerith |
1627 strings are not recognized. Some keywords may be highlighted incorrectly | |
7 | 1628 because Fortran90 has no reserved words. |
1629 | |
501 | 1630 For further information related to fortran, see |ft-fortran-indent| and |
1631 |ft-fortran-plugin|. | |
1632 | |
1633 | |
1634 FVWM CONFIGURATION FILES *fvwm.vim* *ft-fvwm-syntax* | |
7 | 1635 |
1636 In order for Vim to recognize Fvwm configuration files that do not match | |
1637 the patterns *fvwmrc* or *fvwm2rc* , you must put additional patterns | |
1638 appropriate to your system in your myfiletypes.vim file. For these | |
1639 patterns, you must set the variable "b:fvwm_version" to the major version | |
1640 number of Fvwm, and the 'filetype' option to fvwm. | |
1641 | |
1642 For example, to make Vim identify all files in /etc/X11/fvwm2/ | |
1643 as Fvwm2 configuration files, add the following: > | |
1644 | |
1645 :au! BufNewFile,BufRead /etc/X11/fvwm2/* let b:fvwm_version = 2 | | |
1646 \ set filetype=fvwm | |
1647 | |
1648 If you'd like Vim to highlight all valid color names, tell it where to | |
1649 find the color database (rgb.txt) on your system. Do this by setting | |
1650 "rgb_file" to its location. Assuming your color database is located | |
1651 in /usr/X11/lib/X11/, you should add the line > | |
1652 | |
1653 :let rgb_file = "/usr/X11/lib/X11/rgb.txt" | |
1654 | |
1655 to your .vimrc file. | |
1656 | |
1657 | |
501 | 1658 GSP *gsp.vim* *ft-gsp-syntax* |
7 | 1659 |
1660 The default coloring style for GSP pages is defined by |html.vim|, and | |
1661 the coloring for java code (within java tags or inline between backticks) | |
1662 is defined by |java.vim|. The following HTML groups defined in |html.vim| | |
1663 are redefined to incorporate and highlight inline java code: | |
1664 | |
1665 htmlString | |
1666 htmlValue | |
1667 htmlEndTag | |
1668 htmlTag | |
1669 htmlTagN | |
1670 | |
1671 Highlighting should look fine most of the places where you'd see inline | |
1672 java code, but in some special cases it may not. To add another HTML | |
1673 group where you will have inline java code where it does not highlight | |
1674 correctly, just copy the line you want from |html.vim| and add gspJava | |
1675 to the contains clause. | |
1676 | |
1677 The backticks for inline java are highlighted according to the htmlError | |
1678 group to make them easier to see. | |
1679 | |
1680 | |
501 | 1681 GROFF *groff.vim* *ft-groff-syntax* |
7 | 1682 |
1683 The groff syntax file is a wrapper for |nroff.vim|, see the notes | |
237 | 1684 under that heading for examples of use and configuration. The purpose |
7 | 1685 of this wrapper is to set up groff syntax extensions by setting the |
1686 filetype from a |modeline| or in a personal filetype definitions file | |
1687 (see |filetype.txt|). | |
1688 | |
1689 | |
501 | 1690 HASKELL *haskell.vim* *lhaskell.vim* *ft-haskell-syntax* |
7 | 1691 |
1692 The Haskell syntax files support plain Haskell code as well as literate | |
237 | 1693 Haskell code, the latter in both Bird style and TeX style. The Haskell |
7 | 1694 syntax highlighting will also highlight C preprocessor directives. |
1695 | |
1696 If you want to highlight delimiter characters (useful if you have a | |
1697 light-coloured background), add to your .vimrc: > | |
1698 :let hs_highlight_delimiters = 1 | |
1699 To treat True and False as keywords as opposed to ordinary identifiers, | |
1700 add: > | |
1701 :let hs_highlight_boolean = 1 | |
1702 To also treat the names of primitive types as keywords: > | |
1703 :let hs_highlight_types = 1 | |
1704 And to treat the names of even more relatively common types as keywords: > | |
1705 :let hs_highlight_more_types = 1 | |
1706 If you want to highlight the names of debugging functions, put in | |
1707 your .vimrc: > | |
1708 :let hs_highlight_debug = 1 | |
1709 | |
1710 The Haskell syntax highlighting also highlights C preprocessor | |
1711 directives, and flags lines that start with # but are not valid | |
237 | 1712 directives as erroneous. This interferes with Haskell's syntax for |
1713 operators, as they may start with #. If you want to highlight those | |
7 | 1714 as operators as opposed to errors, put in your .vimrc: > |
1715 :let hs_allow_hash_operator = 1 | |
1716 | |
1717 The syntax highlighting for literate Haskell code will try to | |
1718 automatically guess whether your literate Haskell code contains | |
1719 TeX markup or not, and correspondingly highlight TeX constructs | |
237 | 1720 or nothing at all. You can override this globally by putting |
7 | 1721 in your .vimrc > |
1722 :let lhs_markup = none | |
1723 for no highlighting at all, or > | |
1724 :let lhs_markup = tex | |
1725 to force the highlighting to always try to highlight TeX markup. | |
1726 For more flexibility, you may also use buffer local versions of | |
1727 this variable, so e.g. > | |
1728 :let b:lhs_markup = tex | |
237 | 1729 will force TeX highlighting for a particular buffer. It has to be |
7 | 1730 set before turning syntax highlighting on for the buffer or |
1731 loading a file. | |
1732 | |
1733 | |
501 | 1734 HTML *html.vim* *ft-html-syntax* |
7 | 1735 |
1736 The coloring scheme for tags in the HTML file works as follows. | |
1737 | |
1738 The <> of opening tags are colored differently than the </> of a closing tag. | |
1739 This is on purpose! For opening tags the 'Function' color is used, while for | |
1740 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
1741 defined for you) | |
1742 | |
1743 Known tag names are colored the same way as statements in C. Unknown tag | |
1744 names are colored with the same color as the <> or </> respectively which | |
1745 makes it easy to spot errors | |
1746 | |
237 | 1747 Note that the same is true for argument (or attribute) names. Known attribute |
7 | 1748 names are colored differently than unknown ones. |
1749 | |
237 | 1750 Some HTML tags are used to change the rendering of text. The following tags |
7 | 1751 are recognized by the html.vim syntax coloring file and change the way normal |
1752 text is shown: <B> <I> <U> <EM> <STRONG> (<EM> is used as an alias for <I>, | |
1753 while <STRONG> as an alias for <B>), <H1> - <H6>, <HEAD>, <TITLE> and <A>, but | |
237 | 1754 only if used as a link (that is, it must include a href as in |
1224 | 1755 <A href="somefile.html">). |
7 | 1756 |
1757 If you want to change how such text is rendered, you must redefine the | |
1758 following syntax groups: | |
1759 | |
1760 - htmlBold | |
1761 - htmlBoldUnderline | |
1762 - htmlBoldUnderlineItalic | |
1763 - htmlUnderline | |
1764 - htmlUnderlineItalic | |
1765 - htmlItalic | |
1766 - htmlTitle for titles | |
1767 - htmlH1 - htmlH6 for headings | |
1768 | |
1769 To make this redefinition work you must redefine them all with the exception | |
1770 of the last two (htmlTitle and htmlH[1-6], which are optional) and define the | |
1771 following variable in your vimrc (this is due to the order in which the files | |
1772 are read during initialization) > | |
1773 :let html_my_rendering=1 | |
1774 | |
1775 If you'd like to see an example download mysyntax.vim at | |
1776 http://www.fleiner.com/vim/download.html | |
1777 | |
1778 You can also disable this rendering by adding the following line to your | |
1779 vimrc file: > | |
1780 :let html_no_rendering=1 | |
1781 | |
1782 HTML comments are rather special (see an HTML reference document for the | |
1783 details), and the syntax coloring scheme will highlight all errors. | |
1784 However, if you prefer to use the wrong style (starts with <!-- and | |

|
1785 ends with -->) you can define > |
7 | 1786 :let html_wrong_comments=1 |
1787 | |
1788 JavaScript and Visual Basic embedded inside HTML documents are highlighted as | |
1789 'Special' with statements, comments, strings and so on colored as in standard | |
237 | 1790 programming languages. Note that only JavaScript and Visual Basic are currently |
7 | 1791 supported, no other scripting language has been added yet. |
1792 | |
1793 Embedded and inlined cascading style sheets (CSS) are highlighted too. | |
1794 | |
237 | 1795 There are several html preprocessor languages out there. html.vim has been |
1796 written such that it should be trivial to include it. To do so add the | |
7 | 1797 following two lines to the syntax coloring file for that language |
1798 (the example comes from the asp.vim file): | |
18016 | 1799 > |
7 | 1800 runtime! syntax/html.vim |
1801 syn cluster htmlPreproc add=asp | |
1802 | |
1803 Now you just need to make sure that you add all regions that contain | |
1804 the preprocessor language to the cluster htmlPreproc. | |
1805 | |
1806 | |
501 | 1807 HTML/OS (by Aestiva) *htmlos.vim* *ft-htmlos-syntax* |
7 | 1808 |
1809 The coloring scheme for HTML/OS works as follows: | |
1810 | |
1811 Functions and variable names are the same color by default, because VIM | |
1812 doesn't specify different colors for Functions and Identifiers. To change | |
1813 this (which is recommended if you want function names to be recognizable in a | |
1814 different color) you need to add the following line to either your ~/.vimrc: > | |
1815 :hi Function term=underline cterm=bold ctermfg=LightGray | |
1816 | |
1817 Of course, the ctermfg can be a different color if you choose. | |
1818 | |
1819 Another issues that HTML/OS runs into is that there is no special filetype to | |
1820 signify that it is a file with HTML/OS coding. You can change this by opening | |
1821 a file and turning on HTML/OS syntax by doing the following: > | |
1822 :set syntax=htmlos | |
1823 | |
1824 Lastly, it should be noted that the opening and closing characters to begin a | |
1825 block of HTML/OS code can either be << or [[ and >> or ]], respectively. | |
1826 | |
1827 | |
501 | 1828 IA64 *ia64.vim* *intel-itanium* *ft-ia64-syntax* |
7 | 1829 |
1830 Highlighting for the Intel Itanium 64 assembly language. See |asm.vim| for | |
1831 how to recognize this filetype. | |
1832 | |
1833 To have *.inc files be recognized as IA64, add this to your .vimrc file: > | |
1834 :let g:filetype_inc = "ia64" | |
1835 | |
1836 | |
501 | 1837 INFORM *inform.vim* *ft-inform-syntax* |
7 | 1838 |
1839 Inform highlighting includes symbols provided by the Inform Library, as | |
1840 most programs make extensive use of it. If do not wish Library symbols | |
1841 to be highlighted add this to your vim startup: > | |
1842 :let inform_highlight_simple=1 | |
1843 | |
1844 By default it is assumed that Inform programs are Z-machine targeted, | |
1845 and highlights Z-machine assembly language symbols appropriately. If | |
1846 you intend your program to be targeted to a Glulx/Glk environment you | |
1847 need to add this to your startup sequence: > | |
1848 :let inform_highlight_glulx=1 | |
1849 | |
1850 This will highlight Glulx opcodes instead, and also adds glk() to the | |
1851 set of highlighted system functions. | |
1852 | |
1853 The Inform compiler will flag certain obsolete keywords as errors when | |
1854 it encounters them. These keywords are normally highlighted as errors | |
1855 by Vim. To prevent such error highlighting, you must add this to your | |
1856 startup sequence: > | |
1857 :let inform_suppress_obsolete=1 | |
1858 | |
1859 By default, the language features highlighted conform to Compiler | |
1860 version 6.30 and Library version 6.11. If you are using an older | |
1861 Inform development environment, you may with to add this to your | |
1862 startup sequence: > | |
1863 :let inform_highlight_old=1 | |
1864 | |
829 | 1865 IDL *idl.vim* *idl-syntax* |
1866 | |
1867 IDL (Interface Definition Language) files are used to define RPC calls. In | |
1868 Microsoft land, this is also used for defining COM interfaces and calls. | |
1869 | |
1870 IDL's structure is simple enough to permit a full grammar based approach to | |
1871 rather than using a few heuristics. The result is large and somewhat | |
1224 | 1872 repetitive but seems to work. |
829 | 1873 |
1874 There are some Microsoft extensions to idl files that are here. Some of them | |
1875 are disabled by defining idl_no_ms_extensions. | |
1876 | |
1877 The more complex of the extensions are disabled by defining idl_no_extensions. | |

501 | 1889 JAVA *java.vim* *ft-java-syntax* |
7 | 1890 |
1891 The java.vim syntax highlighting file offers several options: | |
1892 | |
1893 In Java 1.0.2 it was never possible to have braces inside parens, so this was | |
1894 flagged as an error. Since Java 1.1 this is possible (with anonymous | |
237 | 1895 classes), and therefore is no longer marked as an error. If you prefer the old |
7 | 1896 way, put the following line into your vim startup file: > |
1897 :let java_mark_braces_in_parens_as_errors=1 | |
1898 | |
1899 All identifiers in java.lang.* are always visible in all classes. To | |
1900 highlight them use: > | |
1901 :let java_highlight_java_lang_ids=1 | |
1902 | |
237 | 1903 You can also highlight identifiers of most standard Java packages if you |
7 | 1904 download the javaid.vim script at http://www.fleiner.com/vim/download.html. |
1905 If you prefer to only highlight identifiers of a certain package, say java.io | |
1906 use the following: > | |
1907 :let java_highlight_java_io=1 | |
1908 Check the javaid.vim file for a list of all the packages that are supported. | |
1909 | |
1910 Function names are not highlighted, as the way to find functions depends on | |
237 | 1911 how you write Java code. The syntax file knows two possible ways to highlight |
7 | 1912 functions: |
1913 | |
1914 If you write function declarations that are always indented by either | |
1915 a tab, 8 spaces or 2 spaces you may want to set > | |
1916 :let java_highlight_functions="indent" | |
1917 However, if you follow the Java guidelines about how functions and classes are | |
1918 supposed to be named (with respect to upper and lowercase), use > | |
1919 :let java_highlight_functions="style" | |
1920 If both options do not work for you, but you would still want function | |
1921 declarations to be highlighted create your own definitions by changing the | |
1922 definitions in java.vim or by creating your own java.vim which includes the | |
1923 original one and then adds the code to highlight functions. | |
1924 | |
237 | 1925 In Java 1.1 the functions System.out.println() and System.err.println() should |
8 | 1926 only be used for debugging. Therefore it is possible to highlight debugging |
237 | 1927 statements differently. To do this you must add the following definition in |
7 | 1928 your startup file: > |
1929 :let java_highlight_debug=1 | |
1930 The result will be that those statements are highlighted as 'Special' | |
237 | 1931 characters. If you prefer to have them highlighted differently you must define |
7 | 1932 new highlightings for the following groups.: |
1933 Debug, DebugSpecial, DebugString, DebugBoolean, DebugType | |
1934 which are used for the statement itself, special characters used in debug | |
237 | 1935 strings, strings, boolean constants and types (this, super) respectively. I |
7 | 1936 have opted to chose another background for those statements. |
1937 | |
237 | 1938 Javadoc is a program that takes special comments out of Java program files and |
1939 creates HTML pages. The standard configuration will highlight this HTML code | |
1940 similarly to HTML files (see |html.vim|). You can even add Javascript | |
1941 and CSS inside this code (see below). There are four differences however: | |
7 | 1942 1. The title (all characters up to the first '.' which is followed by |
1943 some white space or up to the first '@') is colored differently (to change | |
1944 the color change the group CommentTitle). | |
1945 2. The text is colored as 'Comment'. | |
1946 3. HTML comments are colored as 'Special' | |
237 | 1947 4. The special Javadoc tags (@see, @param, ...) are highlighted as specials |
7 | 1948 and the argument (for @see, @param, @exception) as Function. |
1949 To turn this feature off add the following line to your startup file: > | |
1950 :let java_ignore_javadoc=1 | |
1951 | |
237 | 1952 If you use the special Javadoc comment highlighting described above you |
1953 can also turn on special highlighting for Javascript, visual basic | |
1954 scripts and embedded CSS (stylesheets). This makes only sense if you | |
1955 actually have Javadoc comments that include either Javascript or embedded | |
1956 CSS. The options to use are > | |
7 | 1957 :let java_javascript=1 |
1958 :let java_css=1 | |
1959 :let java_vb=1 | |
1960 | |
1961 In order to highlight nested parens with different colors define colors | |
1962 for javaParen, javaParen1 and javaParen2, for example with > | |
1963 :hi link javaParen Comment | |
1964 or > | |
1965 :hi javaParen ctermfg=blue guifg=#0000ff | |
1966 | |
1967 If you notice highlighting errors while scrolling backwards, which are fixed | |
1968 when redrawing with CTRL-L, try setting the "java_minlines" internal variable | |
1969 to a larger number: > | |
1970 :let java_minlines = 50 | |
1971 This will make the syntax synchronization start 50 lines before the first | |
1972 displayed line. The default value is 10. The disadvantage of using a larger | |
1973 number is that redrawing can become slow. | |
1974 | |
1975 | |
18130 | 1976 JSON *json.vim* *ft-json-syntax* |
1977 | |
1978 The json syntax file provides syntax highlighting with conceal support by | |
1979 default. To disable concealment: > | |
1980 let g:vim_json_conceal = 0 | |
1981 | |
1982 To disable syntax highlighting of errors: > | |
1983 let g:vim_json_warnings = 0 | |
1984 | |
1985 | |
501 | 1986 LACE *lace.vim* *ft-lace-syntax* |
7 | 1987 |
1988 Lace (Language for Assembly of Classes in Eiffel) is case insensitive, but the | |
1989 style guide lines are not. If you prefer case insensitive highlighting, just | |
1990 define the vim variable 'lace_case_insensitive' in your startup file: > | |
1991 :let lace_case_insensitive=1 | |
1992 | |
1993 | |
501 | 1994 LEX *lex.vim* *ft-lex-syntax* |
7 | 1995 |
1996 Lex uses brute-force synchronizing as the "^%%$" section delimiter | |
1997 gives no clue as to what section follows. Consequently, the value for > | |
1998 :syn sync minlines=300 | |
1999 may be changed by the user if s/he is experiencing synchronization | |
2000 difficulties (such as may happen with large lex files). | |

555 | 2010 LISP *lisp.vim* *ft-lisp-syntax* |
2011 | |
2012 The lisp syntax highlighting provides two options: > | |
2013 | |
2014 g:lisp_instring : if it exists, then "(...)" strings are highlighted | |
2015 as if the contents of the string were lisp. | |
2016 Useful for AutoLisp. | |
2017 g:lisp_rainbow : if it exists and is nonzero, then differing levels | |
2018 of parenthesization will receive different | |
2019 highlighting. | |
2020 < | |
2021 The g:lisp_rainbow option provides 10 levels of individual colorization for | |
2022 the parentheses and backquoted parentheses. Because of the quantity of | |
2023 colorization levels, unlike non-rainbow highlighting, the rainbow mode | |
2024 specifies its highlighting using ctermfg and guifg, thereby bypassing the | |
16208 | 2025 usual color scheme control using standard highlighting groups. The actual |
555 | 2026 highlighting used depends on the dark/bright setting (see |'bg'|). |
2027 | |
2028 | |
501 | 2029 LITE *lite.vim* *ft-lite-syntax* |
7 | 2030 |
2031 There are two options for the lite syntax highlighting. | |
2032 | |
2033 If you like SQL syntax highlighting inside Strings, use this: > | |
2034 | |
2035 :let lite_sql_query = 1 | |
2036 | |
2037 For syncing, minlines defaults to 100. If you prefer another value, you can | |
2038 set "lite_minlines" to the value you desire. Example: > | |
2039 | |
2040 :let lite_minlines = 200 | |
2041 | |
2042 | |
501 | 2043 LPC *lpc.vim* *ft-lpc-syntax* |
7 | 2044 |
14123 | 2045 LPC stands for a simple, memory-efficient language: Lars Pensjö C. The |
7 | 2046 file name of LPC is usually *.c. Recognizing these files as LPC would bother |
2047 users writing only C programs. If you want to use LPC syntax in Vim, you | |
2048 should set a variable in your .vimrc file: > | |
2049 | |
2050 :let lpc_syntax_for_c = 1 | |
2051 | |
2052 If it doesn't work properly for some particular C or LPC files, use a | |
2053 modeline. For a LPC file: | |
2054 | |
2055 // vim:set ft=lpc: | |
2056 | |
2057 For a C file that is recognized as LPC: | |
2058 | |
2059 // vim:set ft=c: | |
2060 | |
2061 If you don't want to set the variable, use the modeline in EVERY LPC file. | |
2062 | |
2063 There are several implementations for LPC, we intend to support most widely | |
237 | 2064 used ones. Here the default LPC syntax is for MudOS series, for MudOS v22 |
7 | 2065 and before, you should turn off the sensible modifiers, and this will also |
5814 | 2066 assert the new efuns after v22 to be invalid, don't set this variable when |
7 | 2067 you are using the latest version of MudOS: > |
2068 | |
2069 :let lpc_pre_v22 = 1 | |
2070 | |
2071 For LpMud 3.2 series of LPC: > | |
2072 | |
2073 :let lpc_compat_32 = 1 | |
2074 | |
2075 For LPC4 series of LPC: > | |
2076 | |
2077 :let lpc_use_lpc4_syntax = 1 | |
2078 | |
2079 For uLPC series of LPC: | |
2080 uLPC has been developed to Pike, so you should use Pike syntax | |
2081 instead, and the name of your source file should be *.pike | |
2082 | |
2083 | |
501 | 2084 LUA *lua.vim* *ft-lua-syntax* |
7 | 2085 |
3356 | 2086 The Lua syntax file can be used for versions 4.0, 5.0, 5.1 and 5.2 (5.2 is |
838 | 2087 the default). You can select one of these versions using the global variables |
2088 lua_version and lua_subversion. For example, to activate Lua | |
3356 | 2089 5.1 syntax highlighting, set the variables like this: |
838 | 2090 |
2091 :let lua_version = 5 | |
2092 :let lua_subversion = 1 | |
7 | 2093 |
2094 | |
501 | 2095 MAIL *mail.vim* *ft-mail.vim* |
7 | 2096 |
2097 Vim highlights all the standard elements of an email (headers, signatures, | |
237 | 2098 quoted text and URLs / email addresses). In keeping with standard conventions, |
7 | 2099 signatures begin in a line containing only "--" followed optionally by |
2100 whitespaces and end with a newline. | |
2101 | |
2102 Vim treats lines beginning with ']', '}', '|', '>' or a word followed by '>' | |
237 | 2103 as quoted text. However Vim highlights headers and signatures in quoted text |
7 | 2104 only if the text is quoted with '>' (optionally followed by one space). |
2105 | |
2106 By default mail.vim synchronises syntax to 100 lines before the first | |
237 | 2107 displayed line. If you have a slow machine, and generally deal with emails |
7 | 2108 with short headers, you can change this to a smaller value: > |
2109 | |
2110 :let mail_minlines = 30 | |
2111 | |
2112 | |
501 | 2113 MAKE *make.vim* *ft-make-syntax* |

2115 In makefiles, commands are usually highlighted to make it easy for you to spot | |
2116 errors. However, this may be too much coloring for you. You can turn this | |
2117 feature off by using: > | |
2118 | |
2119 :let make_no_commands = 1 | |
2120 | |
2121 | |

2124 Maple V, by Waterloo Maple Inc, supports symbolic algebra. The language | |
2125 supports many packages of functions which are selectively loaded by the user. | |
2126 The standard set of packages' functions as supplied in Maple V release 4 may be | |
2127 highlighted at the user's discretion. Users may place in their .vimrc file: > | |
2128 | |
2129 :let mvpkg_all= 1 | |
2130 | |
2131 to get all package functions highlighted, or users may select any subset by | |
2132 choosing a variable/package from the table below and setting that variable to | |
2133 1, also in their .vimrc file (prior to sourcing | |

7 | 2156 |
2157 If you use C-style comments inside expressions and find it mangles your | |
2158 highlighting, you may want to use extended (slow!) matches for C-style | |
2159 comments: > | |
2160 | |
2161 :let moo_extended_cstyle_comments = 1 | |
2162 | |

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

2324 in your startup file it will try to syntax-hilight html code inside phtml | |

2331 | |
501 | 2332 PASCAL *pascal.vim* *ft-pascal-syntax* |
7 | 2333 |
2334 Files matching "*.p" could be Progress or Pascal. If the automatic detection | |
2335 doesn't work for you, or you don't edit Progress at all, use this in your | |
2336 startup vimrc: > | |
2337 | |
2338 :let filetype_p = "pascal" | |
2339 | |
2340 The Pascal syntax file has been extended to take into account some extensions | |
2341 provided by Turbo Pascal, Free Pascal Compiler and GNU Pascal Compiler. | |
237 | 2342 Delphi keywords are also supported. By default, Turbo Pascal 7.0 features are |
7 | 2343 enabled. If you prefer to stick with the standard Pascal keywords, add the |
2344 following line to your startup file: > | |
2345 | |
2346 :let pascal_traditional=1 | |
2347 | |
2348 To switch on Delphi specific constructions (such as one-line comments, | |
2349 keywords, etc): > | |
2350 | |
2351 :let pascal_delphi=1 | |
2352 | |
2353 | |
2354 The option pascal_symbol_operator controls whether symbol operators such as +, | |
2355 *, .., etc. are displayed using the Operator color or not. To colorize symbol | |
2356 operators, add the following line to your startup file: > | |
2357 | |
2358 :let pascal_symbol_operator=1 | |
2359 | |
2360 Some functions are highlighted by default. To switch it off: > | |
2361 | |
2362 :let pascal_no_functions=1 | |

2364 Furthermore, there are specific variables for some compilers. Besides |
7 | 2365 pascal_delphi, there are pascal_gpc and pascal_fpc. Default extensions try to |

501 | 2386 PERL *perl.vim* *ft-perl-syntax* |
7 | 2387 |
2388 There are a number of possible options to the perl syntax highlighting. | |
2389 | |
4992 | 2390 Inline POD highlighting is now turned on by default. If you don't wish |
2391 to have the added complexity of highlighting POD embedded within Perl | |
2392 files, you may set the 'perl_include_pod' option to 0: > | |
2393 | |
2394 :let perl_include_pod = 0 | |
7 | 2395 |
5968 | 2396 To reduce the complexity of parsing (and increase performance) you can switch |
22 | 2397 off two elements in the parsing of variable names and contents. > |
2398 | |
2399 To handle package references in variable and function names not differently | |
2400 from the rest of the name (like 'PkgName::' in '$PkgName::VarName'): > | |
2401 | |
2402 :let perl_no_scope_in_variables = 1 | |
2403 | |
2404 (In Vim 6.x it was the other way around: "perl_want_scope_in_variables" | |
2405 enabled it.) | |
2406 | |
2407 If you do not want complex things like '@{${"foo"}}' to be parsed: > | |
2408 | |
2409 :let perl_no_extended_vars = 1 | |
2410 | |
26 | 2411 (In Vim 6.x it was the other way around: "perl_extended_vars" enabled it.) |
7 | 2412 |
237 | 2413 The coloring strings can be changed. By default strings and qq friends will be |
2414 highlighted like the first line. If you set the variable | |
7 | 2415 perl_string_as_statement, it will be highlighted as in the second line. |
2416 | |
2417 "hello world!"; qq|hello world|; | |
2418 ^^^^^^^^^^^^^^NN^^^^^^^^^^^^^^^N (unlet perl_string_as_statement) | |
2419 S^^^^^^^^^^^^SNNSSS^^^^^^^^^^^SN (let perl_string_as_statement) | |
2420 | |
2421 (^ = perlString, S = perlStatement, N = None at all) | |
2422 | |
237 | 2423 The syncing has 3 options. The first two switch off some triggering of |
7 | 2424 synchronization and should only be needed in case it fails to work properly. |
2425 If while scrolling all of a sudden the whole screen changes color completely | |
237 | 2426 then you should try and switch off one of those. Let me know if you can figure |
7 | 2427 out the line that causes the mistake. |
2428 | |
2429 One triggers on "^\s*sub\s*" and the other on "^[$@%]" more or less. > | |
2430 | |
2431 :let perl_no_sync_on_sub | |
2432 :let perl_no_sync_on_global_var | |
2433 | |
2434 Below you can set the maximum distance VIM should look for starting points for | |
2435 its attempts in syntax highlighting. > | |
2436 | |
2437 :let perl_sync_dist = 100 | |
2438 | |
2439 If you want to use folding with perl, set perl_fold: > | |
2440 | |
22 | 2441 :let perl_fold = 1 |
2442 | |
2443 If you want to fold blocks in if statements, etc. as well set the following: > | |
2444 | |
2445 :let perl_fold_blocks = 1 | |
7 | 2446 |
4992 | 2447 Subroutines are folded by default if 'perl_fold' is set. If you do not want |
2448 this, you can set 'perl_nofold_subs': > | |
2449 | |
2450 :let perl_nofold_subs = 1 | |
2451 | |
2452 Anonymous subroutines are not folded by default; you may enable their folding | |
2453 via 'perl_fold_anonymous_subs': > | |
2454 | |
2455 :let perl_fold_anonymous_subs = 1 | |
2456 | |
2457 Packages are also folded by default if 'perl_fold' is set. To disable this | |
2458 behavior, set 'perl_nofold_packages': > | |
2459 | |
2460 :let perl_nofold_packages = 1 | |
7 | 2461 |

2464 [note: previously this was called "php3", but since it now also supports php4 | |
2465 it has been renamed to "php"] | |

2517 TeX is a typesetting language, and plaintex is the file type for the "plain" | |
2518 variant of TeX. If you never want your *.tex files recognized as plain TeX, | |
856 | 2519 see |ft-tex-plugin|. |

501 | 2528 PPWIZARD *ppwiz.vim* *ft-ppwiz-syntax* |
7 | 2529 |
2530 PPWizard is a preprocessor for HTML and OS/2 INF files | |
2531 | |
2532 This syntax file has the options: | |
2533 | |
2534 - ppwiz_highlight_defs : determines highlighting mode for PPWizard's | |
237 | 2535 definitions. Possible values are |
7 | 2536 |
2537 ppwiz_highlight_defs = 1 : PPWizard #define statements retain the | |
237 | 2538 colors of their contents (e.g. PPWizard macros and variables) |
7 | 2539 |
2540 ppwiz_highlight_defs = 2 : preprocessor #define and #evaluate | |
2541 statements are shown in a single color with the exception of line | |
2542 continuation symbols | |
2543 | |
2544 The default setting for ppwiz_highlight_defs is 1. | |
2545 | |
2546 - ppwiz_with_html : If the value is 1 (the default), highlight literal | |
2547 HTML code; if 0, treat HTML code like ordinary text. | |
2548 | |
2549 | |
501 | 2550 PHTML *phtml.vim* *ft-phtml-syntax* |
7 | 2551 |
2552 There are two options for the phtml syntax highlighting. | |
2553 | |
2554 If you like SQL syntax highlighting inside Strings, use this: > | |
2555 | |
2556 :let phtml_sql_query = 1 | |
2557 | |
2558 For syncing, minlines defaults to 100. If you prefer another value, you can | |
2559 set "phtml_minlines" to the value you desire. Example: > | |
2560 | |
2561 :let phtml_minlines = 200 | |
2562 | |
2563 | |
501 | 2564 POSTSCRIPT *postscr.vim* *ft-postscr-syntax* |
7 | 2565 |
2566 There are several options when it comes to highlighting PostScript. | |
2567 | |
2568 First which version of the PostScript language to highlight. There are | |
2569 currently three defined language versions, or levels. Level 1 is the original | |
2570 and base version, and includes all extensions prior to the release of level 2. | |
2571 Level 2 is the most common version around, and includes its own set of | |
2572 extensions prior to the release of level 3. Level 3 is currently the highest | |
2573 level supported. You select which level of the PostScript language you want | |
2574 highlighted by defining the postscr_level variable as follows: > | |
2575 | |
2576 :let postscr_level=2 | |
2577 | |
2578 If this variable is not defined it defaults to 2 (level 2) since this is | |
2579 the most prevalent version currently. | |
2580 | |
2581 Note, not all PS interpreters will support all language features for a | |
2582 particular language level. In particular the %!PS-Adobe-3.0 at the start of | |
2583 PS files does NOT mean the PostScript present is level 3 PostScript! | |
2584 | |
2585 If you are working with Display PostScript, you can include highlighting of | |
2586 Display PS language features by defining the postscr_display variable as | |
2587 follows: > | |
2588 | |
2589 :let postscr_display=1 | |
2590 | |
2591 If you are working with Ghostscript, you can include highlighting of | |
2592 Ghostscript specific language features by defining the variable | |
2593 postscr_ghostscript as follows: > | |
2594 | |
2595 :let postscr_ghostscript=1 | |
2596 | |
2597 PostScript is a large language, with many predefined elements. While it | |
2598 useful to have all these elements highlighted, on slower machines this can | |
2599 cause Vim to slow down. In an attempt to be machine friendly font names and | |
2600 character encodings are not highlighted by default. Unless you are working | |
2601 explicitly with either of these this should be ok. If you want them to be | |
2602 highlighted you should set one or both of the following variables: > | |
2603 | |
2604 :let postscr_fonts=1 | |
2605 :let postscr_encodings=1 | |
2606 | |
2607 There is a stylistic option to the highlighting of and, or, and not. In | |
2608 PostScript the function of these operators depends on the types of their | |
2609 operands - if the operands are booleans then they are the logical operators, | |
2610 if they are integers then they are binary operators. As binary and logical | |
2611 operators can be highlighted differently they have to be highlighted one way | |
2612 or the other. By default they are treated as logical operators. They can be | |
2613 highlighted as binary operators by defining the variable | |
2614 postscr_andornot_binary as follows: > | |
2615 | |
2616 :let postscr_andornot_binary=1 | |
2617 < | |
2618 | |
501 | 2619 *ptcap.vim* *ft-printcap-syntax* |
2620 PRINTCAP + TERMCAP *ft-ptcap-syntax* *ft-termcap-syntax* | |
7 | 2621 |
2622 This syntax file applies to the printcap and termcap databases. | |
2623 | |
2624 In order for Vim to recognize printcap/termcap files that do not match | |
2625 the patterns *printcap*, or *termcap*, you must put additional patterns | |
2626 appropriate to your system in your |myfiletypefile| file. For these | |
2627 patterns, you must set the variable "b:ptcap_type" to either "print" or | |
2628 "term", and then the 'filetype' option to ptcap. | |
2629 | |
2630 For example, to make Vim identify all files in /etc/termcaps/ as termcap | |
2631 files, add the following: > | |
2632 | |
2633 :au BufNewFile,BufRead /etc/termcaps/* let b:ptcap_type = "term" | | |
2634 \ set filetype=ptcap | |
2635 | |
2636 If you notice highlighting errors while scrolling backwards, which | |
2637 are fixed when redrawing with CTRL-L, try setting the "ptcap_minlines" | |
2638 internal variable to a larger number: > | |
2639 | |
2640 :let ptcap_minlines = 50 | |
2641 | |
2642 (The default is 20 lines.) | |
2643 | |
2644 | |
501 | 2645 PROGRESS *progress.vim* *ft-progress-syntax* |
7 | 2646 |
2647 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
2648 doesn't work for you, or you don't edit cweb at all, use this in your | |
2649 startup vimrc: > | |
2650 :let filetype_w = "progress" | |
2651 The same happens for "*.i", which could be assembly, and "*.p", which could be | |
2652 Pascal. Use this if you don't use assembly and Pascal: > | |
2653 :let filetype_i = "progress" | |
2654 :let filetype_p = "progress" | |
2655 | |
2656 | |
501 | 2657 PYTHON *python.vim* *ft-python-syntax* |
7 | 2658 |
4186 | 2659 There are six options to control Python syntax highlighting. |
7 | 2660 |
2661 For highlighted numbers: > | |
4186 | 2662 :let python_no_number_highlight = 1 |
7 | 2663 |
2664 For highlighted builtin functions: > | |
4186 | 2665 :let python_no_builtin_highlight = 1 |
7 | 2666 |
2667 For highlighted standard exceptions: > | |
4186 | 2668 :let python_no_exception_highlight = 1 |
2669 | |
2670 For highlighted doctests and code inside: > | |
2671 :let python_no_doctest_highlight = 1 | |
2672 or > | |
2673 :let python_no_doctest_code_highlight = 1 | |
2674 (first option implies second one). | |
7 | 2675 |
2596 | 2676 For highlighted trailing whitespace and mix of spaces and tabs: > |
4186 | 2677 :let python_space_error_highlight = 1 |
7 | 2678 |
2679 If you want all possible Python highlighting (the same as setting the | |
4186 | 2680 preceding last option and unsetting all other ones): > |
7 | 2681 :let python_highlight_all = 1 |
2682 | |
4992 | 2683 Note: only existence of these options matter, not their value. You can replace |
4186 | 2684 1 above with anything. |
2685 | |
501 | 2686 QUAKE *quake.vim* *ft-quake-syntax* |
7 | 2687 |
2688 The Quake syntax definition should work for most any FPS (First Person | |
237 | 2689 Shooter) based on one of the Quake engines. However, the command names vary |
7 | 2690 a bit between the three games (Quake, Quake 2, and Quake 3 Arena) so the |
2691 syntax definition checks for the existence of three global variables to allow | |
237 | 2692 users to specify what commands are legal in their files. The three variables |
7 | 2693 can be set for the following effects: |
2694 | |
2695 set to highlight commands only available in Quake: > | |
2696 :let quake_is_quake1 = 1 | |
2697 | |
2698 set to highlight commands only available in Quake 2: > | |
2699 :let quake_is_quake2 = 1 | |
2700 | |
2701 set to highlight commands only available in Quake 3 Arena: > | |
2702 :let quake_is_quake3 = 1 | |
2703 | |
2704 Any combination of these three variables is legal, but might highlight more | |
2705 commands than are actually available to you by the game. | |
2706 | |
2707 | |
14637 | 2708 R *r.vim* *ft-r-syntax* |
2709 | |
2710 The parsing of R code for syntax highlight starts 40 lines backwards, but you | |
2711 can set a different value in your |vimrc|. Example: > | |
2712 let r_syntax_minlines = 60 | |
2713 | |
2714 You can also turn off syntax highlighting of ROxygen: > | |
2715 let r_syntax_hl_roxygen = 0 | |
2716 | |
2717 enable folding of code delimited by parentheses, square brackets and curly | |
2718 braces: > | |
2719 let r_syntax_folding = 1 | |
2720 | |
2721 and highlight as functions all keywords followed by an opening parenthesis: > | |
2722 let r_syntax_fun_pattern = 1 | |
2723 | |
2724 | |
2725 R MARKDOWN *rmd.vim* *ft-rmd-syntax* | |
2726 | |
2727 To disable syntax highlight of YAML header, add to your |vimrc|: > | |
2728 let rmd_syn_hl_yaml = 0 | |
2729 | |
2730 To disable syntax highlighting of citation keys: > | |
2731 let rmd_syn_hl_citations = 0 | |
2732 | |
2733 To highlight R code in knitr chunk headers: > | |
2734 let rmd_syn_hl_chunk = 1 | |
2735 | |
2736 By default, chunks of R code will be highlighted following the rules of R | |
2737 language. If you want proper syntax highlighting of chunks of other languages, | |
2738 you should add them to either `markdown_fenced_languages` or | |
2739 `rmd_fenced_languages`. For example to properly highlight both R and Python, | |
2740 you may add this to your |vimrc|: > | |
2741 let rmd_fenced_languages = ['r', 'python'] | |
2742 | |
2743 | |
2744 R RESTRUCTURED TEXT *rrst.vim* *ft-rrst-syntax* | |
2745 | |
2746 To highlight R code in knitr chunk headers, add to your |vimrc|: > | |
2747 let rrst_syn_hl_chunk = 1 | |
2748 | |
2749 | |
501 | 2750 READLINE *readline.vim* *ft-readline-syntax* |
7 | 2751 |
2752 The readline library is primarily used by the BASH shell, which adds quite a | |
237 | 2753 few commands and options to the ones already available. To highlight these |
7 | 2754 items as well you can add the following to your |vimrc| or just type it in the |
2755 command line before loading a file with the readline syntax: > | |
2756 let readline_has_bash = 1 | |
2757 | |
2758 This will add highlighting for the commands that BASH (version 2.05a and | |
2759 later, and part earlier) adds. | |
2760 | |
2761 | |
3920 | 2762 RESTRUCTURED TEXT *rst.vim* *ft-rst-syntax* |
2763 | |
15334 | 2764 Syntax highlighting is enabled for code blocks within the document for a |
2765 select number of file types. See $VIMRUNTIME/syntax/rst.vim for the default | |
2766 syntax list. | |
2767 | |
2768 To set a user-defined list of code block syntax highlighting: > | |
3920 | 2769 let rst_syntax_code_list = ['vim', 'lisp', ...] |
15334 | 2770 |
2771 To assign multiple code block types to a single syntax, define | |
2772 `rst_syntax_code_list` as a mapping: > | |
2773 let rst_syntax_code_list = { | |
18719 | 2774 \ 'cpp': ['cpp', 'c++'], |
2775 \ 'bash': ['bash', 'sh'], | |
15334 | 2776 ... |
18719 | 2777 \ } |
15334 | 2778 |
2779 To use color highlighting for emphasis text: > | |

2790 If you notice highlighting errors while scrolling backwards, which are fixed | |
2791 when redrawing with CTRL-L, try setting the "rexx_minlines" internal variable | |
2792 to a larger number: > | |
2793 :let rexx_minlines = 50 | |
2794 This will make the syntax synchronization start 50 lines before the first | |
2795 displayed line. The default value is 10. The disadvantage of using a larger | |
2796 number is that redrawing can become slow. | |
2797 | |
2965 | 2798 Vim tries to guess what type a ".r" file is. If it can't be detected (from |
2799 comment lines), the default is "r". To make the default rexx add this line to | |
2800 your .vimrc: *g:filetype_r* | |

2875 Ruby: Reducing expensive operations ~ |
7 | 2876 |
2877 By default, the "end" keyword is colorized according to the opening statement | |
572 | 2878 of the block it closes. While useful, this feature can be expensive; if you |
7 | 2879 experience slow redrawing (or you are on a terminal with poor color support) |
2880 you may want to turn it off by defining the "ruby_no_expensive" variable: > | |
572 | 2881 |
7 | 2882 :let ruby_no_expensive = 1 |
1224 | 2883 < |
7 | 2884 In this case the same color will be used for all control keywords. |

7 | 2888 If you do want this feature enabled, but notice highlighting errors while |
2889 scrolling backwards, which are fixed when redrawing with CTRL-L, try setting | |
2890 the "ruby_minlines" variable to a value larger than 50: > | |
572 | 2891 |
7 | 2892 :let ruby_minlines = 100 |
1224 | 2893 < |
7 | 2894 Ideally, this value should be a number of lines large enough to embrace your |
2895 largest class or module. | |

2903 :let ruby_spellcheck_strings = 1 |
1224 | 2904 < |
1125 | 2905 |
501 | 2906 SCHEME *scheme.vim* *ft-scheme-syntax* |
17 | 2907 |
13231 | 2908 By default only R7RS keywords are highlighted and properly indented. |
2909 | |
2910 scheme.vim also supports extensions of the CHICKEN Scheme->C compiler. | |
2911 Define b:is_chicken or g:is_chicken, if you need them. | |
17 | 2912 |
2913 | |
501 | 2914 SDL *sdl.vim* *ft-sdl-syntax* |
7 | 2915 |
2916 The SDL highlighting probably misses a few keywords, but SDL has so many | |
2917 of them it's almost impossibly to cope. | |
2918 | |
2919 The new standard, SDL-2000, specifies that all identifiers are | |
2920 case-sensitive (which was not so before), and that all keywords can be | |
237 | 2921 used either completely lowercase or completely uppercase. To have the |
7 | 2922 highlighting reflect this, you can set the following variable: > |
2923 :let sdl_2000=1 | |
2924 | |
237 | 2925 This also sets many new keywords. If you want to disable the old |
7 | 2926 keywords, which is probably a good idea, use: > |
2927 :let SDL_no_96=1 | |
2928 | |
2929 | |
2930 The indentation is probably also incomplete, but right now I am very | |
2931 satisfied with it for my own projects. | |
2932 | |
2933 | |
501 | 2934 SED *sed.vim* *ft-sed-syntax* |
7 | 2935 |
2936 To make tabs stand out from regular blanks (accomplished by using Todo | |
2937 highlighting on the tabs), define "highlight_sedtabs" by putting > | |
2938 | |
2939 :let highlight_sedtabs = 1 | |
2940 | |
2941 in the vimrc file. (This special highlighting only applies for tabs | |
2942 inside search patterns, replacement texts, addresses or text included | |
2943 by an Append/Change/Insert command.) If you enable this option, it is | |
2944 also a good idea to set the tab width to one character; by doing that, | |
2945 you can easily count the number of tabs in a string. | |
2946 | |
2947 Bugs: | |
2948 | |
2949 The transform command (y) is treated exactly like the substitute | |
2950 command. This means that, as far as this syntax file is concerned, | |
2951 transform accepts the same flags as substitute, which is wrong. | |
2952 (Transform accepts no flags.) I tolerate this bug because the | |
2953 involved commands need very complex treatment (95 patterns, one for | |
2954 each plausible pattern delimiter). | |
2955 | |
2956 | |
501 | 2957 SGML *sgml.vim* *ft-sgml-syntax* |
7 | 2958 |
2959 The coloring scheme for tags in the SGML file works as follows. | |
2960 | |
2961 The <> of opening tags are colored differently than the </> of a closing tag. | |
2962 This is on purpose! For opening tags the 'Function' color is used, while for | |
2963 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
2964 defined for you) | |
2965 | |
2966 Known tag names are colored the same way as statements in C. Unknown tag | |
2967 names are not colored which makes it easy to spot errors. | |
2968 | |
237 | 2969 Note that the same is true for argument (or attribute) names. Known attribute |
7 | 2970 names are colored differently than unknown ones. |
2971 | |
237 | 2972 Some SGML tags are used to change the rendering of text. The following tags |
7 | 2973 are recognized by the sgml.vim syntax coloring file and change the way normal |
2974 text is shown: <varname> <emphasis> <command> <function> <literal> | |
2975 <replaceable> <ulink> and <link>. | |
2976 | |
2977 If you want to change how such text is rendered, you must redefine the | |
2978 following syntax groups: | |
2979 | |
2980 - sgmlBold | |
2981 - sgmlBoldItalic | |
2982 - sgmlUnderline | |
2983 - sgmlItalic | |
2984 - sgmlLink for links | |
2985 | |
2986 To make this redefinition work you must redefine them all and define the | |
2987 following variable in your vimrc (this is due to the order in which the files | |
2988 are read during initialization) > | |
2989 let sgml_my_rendering=1 | |
2990 | |
2991 You can also disable this rendering by adding the following line to your | |
2992 vimrc file: > | |
2993 let sgml_no_rendering=1 | |
2994 | |

3002 shells such as bash, dash, posix, and the Korn shells. |
7 | 3003 |
3004 Vim attempts to determine which shell type is in use by specifying that | |
14421 | 3005 various filenames are of specific types, e.g.: > |
7 | 3006 |
3007 ksh : .kshrc* *.ksh | |
3008 bash: .bashrc* bashrc bash.bashrc .bash_profile* *.bash | |
3009 < | |
14421 | 3010 See $VIMRUNTIME/filetype.vim for the full list of patterns. If none of these |
3011 cases pertain, then the first line of the file is examined (ex. looking for | |
3012 /bin/sh /bin/ksh /bin/bash). If the first line specifies a shelltype, then | |
3013 that shelltype is used. However some files (ex. .profile) are known to be | |
3014 shell files but the type is not apparent. Furthermore, on many systems sh is | |
3015 symbolically linked to "bash" (Linux, Windows+cygwin) or "ksh" (Posix). | |

3044 then various syntax items (ie. HereDocuments and function bodies) become |
1624 | 3045 syntax-foldable (see |:syn-fold|). You also may add these together |
3046 to get multiple types of folding: > | |
3047 | |
3048 let g:sh_fold_enabled= 3 (enables function and heredoc folding) | |
3049 | |
3050 If you notice highlighting errors while scrolling backwards which are fixed | |
3051 when one redraws with CTRL-L, try setting the "sh_minlines" internal variable | |
7 | 3052 to a larger number. Example: > |
3053 | |
3054 let sh_minlines = 500 | |
3055 | |
3056 This will make syntax synchronization start 500 lines before the first | |
3057 displayed line. The default value is 200. The disadvantage of using a larger | |
3058 number is that redrawing can become slow. | |
3059 | |
3060 If you don't have much to synchronize on, displaying can be very slow. To | |
3061 reduce this, the "sh_maxlines" internal variable can be set. Example: > | |
3062 | |
3063 let sh_maxlines = 100 | |
3064 < | |
3065 The default is to use the twice sh_minlines. Set it to a smaller number to | |
3066 speed up displaying. The disadvantage is that highlight errors may appear. | |

3102 (AspenTech plant simulator) |
7 | 3103 |
3104 The Speedup syntax file has some options: | |
3105 | |
3106 - strict_subsections : If this variable is defined, only keywords for | |
3107 sections and subsections will be highlighted as statements but not | |
3108 other keywords (like WITHIN in the OPERATION section). | |
3109 | |
3110 - highlight_types : Definition of this variable causes stream types | |
3111 like temperature or pressure to be highlighted as Type, not as a | |
237 | 3112 plain Identifier. Included are the types that are usually found in |
7 | 3113 the DECLARE section; if you defined own types, you have to include |
3114 them in the syntax file. | |
3115 | |
3116 - oneline_comments : this value ranges from 1 to 3 and determines the | |
3117 highlighting of # style comments. | |
3118 | |
3119 oneline_comments = 1 : allow normal Speedup code after an even | |
3120 number of #s. | |
3121 | |
3122 oneline_comments = 2 : show code starting with the second # as | |
237 | 3123 error. This is the default setting. |
7 | 3124 |
3125 oneline_comments = 3 : show the whole line as error if it contains | |
3126 more than one #. | |
3127 | |
3128 Since especially OPERATION sections tend to become very large due to | |
237 | 3129 PRESETting variables, syncing may be critical. If your computer is |
7 | 3130 fast enough, you can increase minlines and/or maxlines near the end of |
3131 the syntax file. | |

3137 | |
3138 While there is an ANSI standard for SQL, most database engines add their own | |
3139 custom extensions. Vim currently supports the Oracle and Informix dialects of | |
3140 SQL. Vim assumes "*.sql" files are Oracle SQL by default. | |
3141 | |
3142 Vim currently has SQL support for a variety of different vendors via syntax | |
3143 scripts. You can change Vim's default from Oracle to any of the current SQL | |
3144 supported types. You can also easily alter the SQL dialect being used on a | |
3145 buffer by buffer basis. | |

3153 for how the filetype is detected. | |
3154 | |
3155 Tcsh does not allow \" in strings unless the "backslash_quote" shell variable | |
237 | 3156 is set. If you want VIM to assume that no backslash quote constructs exist add |
7 | 3157 this line to your .vimrc: > |
3158 | |
3159 :let tcsh_backslash_quote = 0 | |
3160 | |

3236 terminate properly, zones delineated by $..$ and $$..$$ cannot be synchronized | |
3237 as there's no difference between start and end patterns. Consequently, a | |
7 | 3238 special "TeX comment" has been provided > |
3239 %stopzone | |

3258 Finally, if syntax highlighting is still too slow, you may set > | |
3259 | |
3260 :let g:tex_fast= "" | |
3261 | |
3262 in your .vimrc. Used this way, the g:tex_fast variable causes the syntax | |
3263 highlighting script to avoid defining any regions and associated | |
3264 synchronization. The result will be much faster syntax highlighting; the | |
3265 price: you will no longer have as much highlighting or any syntax-based | |
3266 folding, and you will be missing syntax-based error checking. | |
3267 | |
3268 You may decide that some syntax is acceptable; you may use the following table | |
3269 selectively to enable just some syntax highlighting: > | |
3270 | |
3271 b : allow bold and italic syntax | |
3272 c : allow texComment syntax | |
3273 m : allow texMatcher syntax (ie. {...} and [...]) | |
3274 M : allow texMath syntax | |
3275 p : allow parts, chapter, section, etc syntax | |
3276 r : allow texRefZone syntax (nocite, bibliography, label, pageref, eqref) | |
3277 s : allow superscript/subscript regions | |
3278 S : allow texStyle syntax | |
3279 v : allow verbatim syntax | |
3280 V : allow texNewEnv and texNewCmd syntax | |

3287 Tex: Want To Highlight More Commands? ~ |
1125 | 3288 |
3289 LaTeX is a programmable language, and so there are thousands of packages full | |
3290 of specialized LaTeX commands, syntax, and fonts. If you're using such a | |
3291 package you'll often wish that the distributed syntax/tex.vim would support | |
3292 it. However, clearly this is impractical. So please consider using the | |
3293 techniques in |mysyntaxfile-add| to extend or modify the highlighting provided | |
3237 | 3294 by syntax/tex.vim. Please consider uploading any extensions that you write, |
3295 which typically would go in $HOME/after/syntax/tex/[pkgname].vim, to | |
3296 http://vim.sf.net/. | |

3317 If you want to include a new math group in your LaTeX, the following | |
3318 code shows you an example as to how you might do so: > | |
477 | 3319 call TexNewMathZone(sfx,mathzone,starform) |
3320 You'll want to provide the new math group with a unique suffix | |
3321 (currently, A-L and V-Z are taken by <syntax/tex.vim> itself). | |
3322 As an example, consider how eqnarray is set up by <syntax/tex.vim>: > | |
3323 call TexNewMathZone("D","eqnarray",1) | |
3324 You'll need to change "mathzone" to the name of your new math group, | |
3325 and then to the call to it in .vim/after/syntax/tex.vim. | |
3326 The "starform" variable, if true, implies that your new math group | |
3327 has a starred form (ie. eqnarray*). | |

3332 One may use "\makeatletter" in *.tex files, thereby making the use of "@" in | |
3333 commands available. However, since the *.tex file doesn't have one of the | |
3334 following suffices: sty cls clo dtx ltx, the syntax highlighting will flag | |
3335 such use of @ as an error. To solve this: > | |

3344 Tex: Taking Advantage of Conceal Mode~ |
2417 | 3345 |
2426 | 3346 If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a |
3347 number of character sequences can be translated into appropriate utf-8 glyphs, | |
3348 including various accented characters, Greek characters in MathZones, and | |
3349 superscripts and subscripts in MathZones. Not all characters can be made into | |
3350 superscripts or subscripts; the constraint is due to what utf-8 supports. | |
3351 In fact, only a few characters are supported as subscripts. | |
3352 | |
3353 One way to use this is to have vertically split windows (see |CTRL-W_v|); one | |
3354 with |'conceallevel'| at 0 and the other at 2; and both using |'scrollbind'|. | |

3374 Tex: Controlling iskeyword~ | |
3375 | |
3376 Normally, LaTeX keywords support 0-9, a-z, A-z, and 192-255 only. Latex | |
3377 keywords don't support the underscore - except when in *.sty files. The | |
3378 syntax highlighting script handles this with the following logic: | |
3379 | |
3380 * If g:tex_stylish exists and is 1 | |
3381 then the file will be treated as a "sty" file, so the "_" | |
3382 will be allowed as part of keywords | |

3396 | |
3397 See |g:tex_conceal| for selectively concealing accents, bold/italic, | |
3398 math, Greek, and superscripts/subscripts. | |
3399 | |
3400 One may exert fine control over which superscripts and subscripts one | |
3401 wants syntax-based concealment for (see |:syn-cchar|). Since not all | |
3402 fonts support all characters, one may override the | |
3403 concealed-replacement lists; by default these lists are given by: > | |
3404 | |
3405 let g:tex_superscripts= "[0-9a-zA-W.,:;+-<>/()=]" | |
3406 let g:tex_subscripts= "[0-9aehijklmnoprstuvx,+-/().]" | |
3407 < | |
3408 For example, I use Luxi Mono Bold; it doesn't support subscript | |
3409 characters for "hklmnpst", so I put > | |
3410 let g:tex_subscripts= "[0-9aeijoruvx,+-/().]" | |
3411 < in ~/.vim/ftplugin/tex/tex.vim in order to avoid having inscrutable | |
3412 utf-8 glyphs appear. | |

3469 is a difficult language to highlight correctly. A way to suppress error |
1624 | 3470 highlighting is to put the following line in your |vimrc|: > |

3472 let g:vimsyn_noerror = 1 | |
3473 < | |

7 | 3475 |
501 | 3476 XF86CONFIG *xf86conf.vim* *ft-xf86conf-syntax* |
7 | 3477 |
3478 The syntax of XF86Config file differs in XFree86 v3.x and v4.x. Both | |
3479 variants are supported. Automatic detection is used, but is far from perfect. | |
3480 You may need to specify the version manually. Set the variable | |
3481 xf86conf_xfree86_version to 3 or 4 according to your XFree86 version in | |
3482 your .vimrc. Example: > | |
3483 :let xf86conf_xfree86_version=3 | |
3484 When using a mix of versions, set the b:xf86conf_xfree86_version variable. | |
3485 | |
3486 Note that spaces and underscores in option names are not supported. Use | |
3487 "SyncOnGreen" instead of "__s yn con gr_e_e_n" if you want the option name | |
3488 highlighted. | |
3489 | |
3490 | |
501 | 3491 XML *xml.vim* *ft-xml-syntax* |
7 | 3492 |
237 | 3493 Xml namespaces are highlighted by default. This can be inhibited by |
7 | 3494 setting a global variable: > |
3495 | |
3496 :let g:xml_namespace_transparent=1 | |
3497 < | |
3498 *xml-folding* | |
3499 The xml syntax file provides syntax |folding| (see |:syn-fold|) between | |
237 | 3500 start and end tags. This can be turned on by > |
7 | 3501 |
3502 :let g:xml_syntax_folding = 1 | |
3503 :set foldmethod=syntax | |
3504 | |
3505 Note: syntax folding might slow down syntax highlighting significantly, | |
3506 especially for large files. | |
3507 | |
3508 | |
501 | 3509 X Pixmaps (XPM) *xpm.vim* *ft-xpm-syntax* |
7 | 3510 |
3511 xpm.vim creates its syntax items dynamically based upon the contents of the | |
3512 XPM file. Thus if you make changes e.g. in the color specification strings, | |
3513 you have to source it again e.g. with ":set syn=xpm". | |
3514 | |
3515 To copy a pixel with one of the colors, yank a "pixel" with "yl" and insert it | |
3516 somewhere else with "P". | |
3517 | |
3518 Do you want to draw with the mouse? Try the following: > | |
3519 :function! GetPixel() | |
823 | 3520 : let c = getline(".")[col(".") - 1] |
7 | 3521 : echo c |
3522 : exe "noremap <LeftMouse> <LeftMouse>r".c | |
3523 : exe "noremap <LeftDrag> <LeftMouse>r".c | |
3524 :endfunction | |
3525 :noremap <RightMouse> <LeftMouse>:call GetPixel()<CR> | |
3526 :set guicursor=n:hor20 " to see the color beneath the cursor | |
3527 This turns the right button into a pipette and the left button into a pen. | |
3528 It will work with XPM files that have one character per pixel only and you | |
3529 must not click outside of the pixel strings, but feel free to improve it. | |
3530 | |
3531 It will look much better with a font in a quadratic cell size, e.g. for X: > | |
3532 :set guifont=-*-clean-medium-r-*-*-8-*-*-*-*-80-* | |
3533 | |
6741 | 3534 |
3535 YAML *yaml.vim* *ft-yaml-syntax* | |
3536 | |
3537 *g:yaml_schema* *b:yaml_schema* | |
3538 A YAML schema is a combination of a set of tags and a mechanism for resolving | |
3539 non-specific tags. For user this means that YAML parser may, depending on | |
3540 plain scalar contents, treat plain scalar (which can actually be only string | |
3541 and nothing else) as a value of the other type: null, boolean, floating-point, | |
3542 integer. `g:yaml_schema` option determines according to which schema values | |
3543 will be highlighted specially. Supported schemas are | |
3544 | |
3545 Schema Description ~ | |
3546 failsafe No additional highlighting. | |
3547 json Supports JSON-style numbers, booleans and null. | |
3548 core Supports more number, boolean and null styles. | |
3549 pyyaml In addition to core schema supports highlighting timestamps, | |
3550 but there are some differences in what is recognized as | |
3551 numbers and many additional boolean values not present in core | |
3552 schema. | |
3553 | |
3554 Default schema is `core`. | |
3555 | |
3556 Note that schemas are not actually limited to plain scalars, but this is the | |
3557 only difference between schemas defined in YAML specification and the only | |
3558 difference defined in the syntax file. | |

7 | 3567 ============================================================================== |
15194 | 3568 6. Defining a syntax *:syn-define* *E410* |
7 | 3569 |
3570 Vim understands three types of syntax items: | |
3571 | |
419 | 3572 1. Keyword |
7 | 3573 It can only contain keyword characters, according to the 'iskeyword' |
3574 option. It cannot contain other syntax items. It will only match with a | |
3575 complete word (there are no keyword characters before or after the match). | |
3576 The keyword "if" would match in "if(a=b)", but not in "ifdef x", because | |
3577 "(" is not a keyword character and "d" is. | |
3578 | |
419 | 3579 2. Match |
7 | 3580 This is a match with a single regexp pattern. |
3581 | |
419 | 3582 3. Region |
7 | 3583 This starts at a match of the "start" regexp pattern and ends with a match |
3584 with the "end" regexp pattern. Any other text can appear in between. A | |
3585 "skip" regexp pattern can be used to avoid matching the "end" pattern. | |
3586 | |
3587 Several syntax ITEMs can be put into one syntax GROUP. For a syntax group | |
3588 you can give highlighting attributes. For example, you could have an item | |
3589 to define a "/* .. */" comment and another one that defines a "// .." comment, | |
3590 and put them both in the "Comment" group. You can then specify that a | |
3591 "Comment" will be in bold font and have a blue color. You are free to make | |
3592 one highlight group for one syntax item, or put all items into one group. | |
3593 This depends on how you want to specify your highlighting attributes. Putting | |
3594 each item in its own group results in having to specify the highlighting | |
3595 for a lot of groups. | |
3596 | |
3597 Note that a syntax group and a highlight group are similar. For a highlight | |
3598 group you will have given highlight attributes. These attributes will be used | |
3599 for the syntax group with the same name. | |
3600 | |
3601 In case more than one item matches at the same position, the one that was | |
3602 defined LAST wins. Thus you can override previously defined syntax items by | |
3603 using an item that matches the same text. But a keyword always goes before a | |
3604 match or region. And a keyword with matching case always goes before a | |
3605 keyword with ignoring case. | |
3606 | |
3607 | |
3608 PRIORITY *:syn-priority* | |
3609 | |
3610 When several syntax items may match, these rules are used: | |
3611 | |
3612 1. When multiple Match or Region items start in the same position, the item | |
3613 defined last has priority. | |
3614 2. A Keyword has priority over Match and Region items. | |
3615 3. An item that starts in an earlier position has priority over items that | |
3616 start in later positions. | |
3617 | |
3618 | |
3619 DEFINING CASE *:syn-case* *E390* | |
3620 | |
419 | 3621 :sy[ntax] case [match | ignore] |
7 | 3622 This defines if the following ":syntax" commands will work with |
3623 matching case, when using "match", or with ignoring case, when using | |
3624 "ignore". Note that any items before this are not affected, and all | |
3625 items until the next ":syntax case" command are affected. | |
3626 | |
10734 | 3627 :sy[ntax] case |
3628 Show either "syntax case match" or "syntax case ignore" (translated). | |
7 | 3629 |
419 | 3630 SPELL CHECKING *:syn-spell* |
3631 | |
3632 :sy[ntax] spell [toplevel | notoplevel | default] | |
3633 This defines where spell checking is to be done for text that is not | |
3634 in a syntax item: | |
3635 | |
3636 toplevel: Text is spell checked. | |
3637 notoplevel: Text is not spell checked. | |
3638 default: When there is a @Spell cluster no spell checking. | |
3639 | |
3640 For text in syntax items use the @Spell and @NoSpell clusters | |
3641 |spell-syntax|. When there is no @Spell and no @NoSpell cluster then | |
3642 spell checking is done for "default" and "toplevel". | |
3643 | |
3644 To activate spell checking the 'spell' option must be set. | |
3645 | |
10734 | 3646 :sy[ntax] spell |
3647 Show either "syntax spell toplevel", "syntax spell notoplevel" or | |
3648 "syntax spell default" (translated). | |

3703 Don't forget that a keyword can only be recognized if all the | |
3704 characters are included in the 'iskeyword' option. If one character | |
3705 isn't, the keyword will never be recognized. | |
3706 Multi-byte characters can also be used. These do not have to be in | |
3707 'iskeyword'. | |

3708 See |:syn-iskeyword| for defining syntax specific iskeyword settings. |
7 | 3709 |
3710 A keyword always has higher priority than a match or region, the | |
3711 keyword is used if more than one item matches. Keywords do not nest | |
3712 and a keyword can't contain anything else. | |
3713 | |
3714 Note that when you have a keyword that is the same as an option (even | |
3715 one that isn't allowed here), you can not use it. Use a match | |
3716 instead. | |
3717 | |
3718 The maximum length of a keyword is 80 characters. | |
3719 | |
3720 The same keyword can be defined multiple times, when its containment | |
3721 differs. For example, you can define the keyword once not contained | |
3722 and use one highlight group, and once contained, and use a different | |
237 | 3723 highlight group. Example: > |
7 | 3724 :syn keyword vimCommand tag |
3725 :syn keyword vimSetting contained tag | |
3726 < When finding "tag" outside of any syntax item, the "vimCommand" | |
3727 highlight group is used. When finding "tag" in a syntax item that | |
3728 contains "vimSetting", the "vimSetting" group is used. | |

3748 |:syn-keepend|. |
7 | 3749 {pattern} The search pattern that defines the match. |
3750 See |:syn-pattern| below. | |
3751 Note that the pattern may match more than one | |
3752 line, which makes the match depend on where | |
3753 Vim starts searching for the pattern. You | |
3754 need to make sure syncing takes care of this. | |
3755 | |
3756 Example (match a character constant): > | |
3757 :syntax match Character /'.'/hs=s+1,he=e-1 | |
3758 < | |

3768 [skip={skip_pattern}] | |
3769 end={end_pattern} .. | |
3770 [{options}] | |
3771 | |
3772 This defines one region. It may span several lines. | |
3773 | |
3774 {group-name} A syntax group name such as "Comment". | |
3775 [{options}] See |:syn-arguments| below. | |
3776 [matchgroup={group-name}] The syntax group to use for the following | |
3777 start or end pattern matches only. Not used | |
3778 for the text in between the matched start and | |
3779 end patterns. Use NONE to reset to not using | |
3780 a different group for the start or end match. | |
3781 See |:syn-matchgroup|. | |
3782 keepend Don't allow contained matches to go past a | |
3783 match with the end pattern. See | |
3784 |:syn-keepend|. | |
3785 extend Override a "keepend" for an item this region | |
237 | 3786 is contained in. See |:syn-extend|. |
7 | 3787 excludenl Don't make a pattern with the end-of-line "$" |
3788 extend a containing match or item. Only | |
3789 useful for end patterns. Must be given before | |
3790 the patterns it applies to. |:syn-excludenl| | |
3791 start={start_pattern} The search pattern that defines the start of | |
3792 the region. See |:syn-pattern| below. | |
3793 skip={skip_pattern} The search pattern that defines text inside | |
3794 the region where not to look for the end | |
3795 pattern. See |:syn-pattern| below. | |
3796 end={end_pattern} The search pattern that defines the end of | |
3797 the region. See |:syn-pattern| below. | |
3798 | |
3799 Example: > | |
3800 :syntax region String start=+"+ skip=+\\"+ end=+"+ | |
3801 < | |
3802 The start/skip/end patterns and the options can be given in any order. | |
3803 There can be zero or one skip pattern. There must be one or more | |
3804 start and end patterns. This means that you can omit the skip | |
3805 pattern, but you must give at least one start and one end pattern. It | |
3806 is allowed to have white space before and after the equal sign | |
3807 (although it mostly looks better without white space). | |
3808 | |
3809 When more than one start pattern is given, a match with one of these | |
3810 is sufficient. This means there is an OR relation between the start | |
3811 patterns. The last one that matches is used. The same is true for | |
3812 the end patterns. | |
3813 | |
3814 The search for the end pattern starts right after the start pattern. | |
3815 Offsets are not used for this. This implies that the match for the | |
3816 end pattern will never overlap with the start pattern. | |
3817 | |
3818 The skip and end pattern can match across line breaks, but since the | |
3819 search for the pattern can start in any line it often does not do what | |
3820 you want. The skip pattern doesn't avoid a match of an end pattern in | |
3821 the next line. Use single-line patterns to avoid trouble. | |
3822 | |
3823 Note: The decision to start a region is only based on a matching start | |
3824 pattern. There is no check for a matching end pattern. This does NOT | |
3825 work: > | |
3826 :syn region First start="(" end=":" | |
3827 :syn region Second start="(" end=";" | |
3828 < The Second always matches before the First (last defined pattern has | |
3829 higher priority). The Second region then continues until the next | |
3830 ';', no matter if there is a ':' before it. Using a match does work: > | |
3831 :syn match First "(\_.\{-}:" | |
3832 :syn match Second "(\_.\{-};" | |
3833 < This pattern matches any character or line break with "\_." and | |
3834 repeats that with "\{-}" (repeat as few as possible). | |
3835 | |
3836 *:syn-keepend* | |
3837 By default, a contained match can obscure a match for the end pattern. | |
3838 This is useful for nesting. For example, a region that starts with | |
3839 "{" and ends with "}", can contain another region. An encountered "}" | |
3840 will then end the contained region, but not the outer region: | |
3841 { starts outer "{}" region | |
3842 { starts contained "{}" region | |
3843 } ends contained "{}" region | |
3844 } ends outer "{} region | |
3845 If you don't want this, the "keepend" argument will make the matching | |
3846 of an end pattern of the outer region also end any contained item. | |
3847 This makes it impossible to nest the same region, but allows for | |
3848 contained items to highlight parts of the end pattern, without causing | |
3849 that to skip the match with the end pattern. Example: > | |
3850 :syn match vimComment +"[^"]\+$+ | |
3851 :syn region vimCommand start="set" end="$" contains=vimComment keepend | |
3852 < The "keepend" makes the vimCommand always end at the end of the line, | |
3853 even though the contained vimComment includes a match with the <EOL>. | |
3854 | |
3855 When "keepend" is not used, a match with an end pattern is retried | |
3856 after each contained match. When "keepend" is included, the first | |
3857 encountered match with an end pattern is used, truncating any | |
3858 contained matches. | |
3859 *:syn-extend* | |
3860 The "keepend" behavior can be changed by using the "extend" argument. | |
3861 When an item with "extend" is contained in an item that uses | |
3862 "keepend", the "keepend" is ignored and the containing region will be | |
3863 extended. | |
3864 This can be used to have some contained items extend a region while | |
3865 others don't. Example: > | |
3866 | |
3867 :syn region htmlRef start=+<a>+ end=+</a>+ keepend contains=htmlItem,htmlScript | |
3868 :syn match htmlItem +<[^>]*>+ contained | |
3869 :syn region htmlScript start=+<script+ end=+</script[^>]*>+ contained extend | |
3870 | |
3871 < Here the htmlItem item does not make the htmlRef item continue | |
3872 further, it is only used to highlight the <> items. The htmlScript | |
3873 item does extend the htmlRef item. | |
3874 | |
3875 Another example: > | |
3876 :syn region xmlFold start="<a>" end="</a>" fold transparent keepend extend | |
3877 < This defines a region with "keepend", so that its end cannot be | |
3878 changed by contained items, like when the "</a>" is matched to | |
3879 highlight it differently. But when the xmlFold region is nested (it | |
3880 includes itself), the "extend" applies, so that the "</a>" of a nested | |
3881 region only ends that region, and not the one it is contained in. | |
3882 | |
3883 *:syn-excludenl* | |
3884 When a pattern for a match or end pattern of a region includes a '$' | |
3885 to match the end-of-line, it will make a region item that it is | |
3886 contained in continue on the next line. For example, a match with | |
3887 "\\$" (backslash at the end of the line) can make a region continue | |
3888 that would normally stop at the end of the line. This is the default | |
3889 behavior. If this is not wanted, there are two ways to avoid it: | |
3890 1. Use "keepend" for the containing item. This will keep all | |
3891 contained matches from extending the match or region. It can be | |
3892 used when all contained items must not extend the containing item. | |
3893 2. Use "excludenl" in the contained item. This will keep that match | |
3894 from extending the containing match or region. It can be used if | |
3895 only some contained items must not extend the containing item. | |
3896 "excludenl" must be given before the pattern it applies to. | |
3897 | |
3898 *:syn-matchgroup* | |
3899 "matchgroup" can be used to highlight the start and/or end pattern | |
3900 differently than the body of the region. Example: > | |
3901 :syntax region String matchgroup=Quote start=+"+ skip=+\\"+ end=+"+ | |
3902 < This will highlight the quotes with the "Quote" group, and the text in | |
3903 between with the "String" group. | |
3904 The "matchgroup" is used for all start and end patterns that follow, | |
3905 until the next "matchgroup". Use "matchgroup=NONE" to go back to not | |
3906 using a matchgroup. | |
3907 | |
3908 In a start or end pattern that is highlighted with "matchgroup" the | |
3909 contained items of the region are not used. This can be used to avoid | |
3910 that a contained item matches in the start or end pattern match. When | |
3911 using "transparent", this does not apply to a start or end pattern | |
3912 match that is highlighted with "matchgroup". | |
3913 | |
3914 Here is an example, which highlights three levels of parentheses in | |
3915 different colors: > | |
3916 :sy region par1 matchgroup=par1 start=/(/ end=/)/ contains=par2 | |
3917 :sy region par2 matchgroup=par2 start=/(/ end=/)/ contains=par3 contained | |
3918 :sy region par3 matchgroup=par3 start=/(/ end=/)/ contains=par1 contained | |
3919 :hi par1 ctermfg=red guifg=red | |
3920 :hi par2 ctermfg=blue guifg=blue | |
3921 :hi par3 ctermfg=darkgreen guifg=darkgreen | |

3977 See |hl-Conceal| for highlighting. |
7 | 3978 |
3979 contained *:syn-contained* | |
3980 | |
3981 When the "contained" argument is given, this item will not be recognized at | |
3982 the top level, but only when it is mentioned in the "contains" field of | |
3983 another match. Example: > | |
3984 :syntax keyword Todo TODO contained | |
3985 :syntax match Comment "//.*" contains=Todo | |
3986 | |
3987 | |
3988 display *:syn-display* | |
3989 | |
3990 If the "display" argument is given, this item will be skipped when the | |
3991 detected highlighting will not be displayed. This will speed up highlighting, | |
3992 by skipping this item when only finding the syntax state for the text that is | |
3993 to be displayed. | |
3994 | |
3995 Generally, you can use "display" for match and region items that meet these | |
3996 conditions: | |
3997 - The item does not continue past the end of a line. Example for C: A region | |
3998 for a "/*" comment can't contain "display", because it continues on the next | |
3999 line. | |
4000 - The item does not contain items that continue past the end of the line or | |
4001 make it continue on the next line. | |
4002 - The item does not change the size of any item it is contained in. Example | |
4003 for C: A match with "\\$" in a preprocessor match can't have "display", | |
4004 because it may make that preprocessor match shorter. | |
4005 - The item does not allow other items to match that didn't match otherwise, | |
4006 and that item may extend the match too far. Example for C: A match for a | |
4007 "//" comment can't use "display", because a "/*" inside that comment would | |
4008 match then and start a comment which extends past the end of the line. | |
4009 | |
4010 Examples, for the C language, where "display" can be used: | |
4011 - match with a number | |
4012 - match with a label | |
4013 | |
4014 | |
4015 transparent *:syn-transparent* | |
4016 | |
4017 If the "transparent" argument is given, this item will not be highlighted | |
4018 itself, but will take the highlighting of the item it is contained in. This | |
4019 is useful for syntax items that don't need any highlighting but are used | |
4020 only to skip over a part of the text. | |
4021 | |
4022 The "contains=" argument is also inherited from the item it is contained in, | |
4023 unless a "contains" argument is given for the transparent item itself. To | |
4024 avoid that unwanted items are contained, use "contains=NONE". Example, which | |
4025 highlights words in strings, but makes an exception for "vim": > | |
4026 :syn match myString /'[^']*'/ contains=myWord,myVim | |
4027 :syn match myWord /\<[a-z]*\>/ contained | |
4028 :syn match myVim /\<vim\>/ transparent contained contains=NONE | |
4029 :hi link myString String | |
4030 :hi link myWord Comment | |
4031 Since the "myVim" match comes after "myWord" it is the preferred match (last | |
4032 match in the same position overrules an earlier one). The "transparent" | |
4033 argument makes the "myVim" match use the same highlighting as "myString". But | |
4034 it does not contain anything. If the "contains=NONE" argument would be left | |
4035 out, then "myVim" would use the contains argument from myString and allow | |
4036 "myWord" to be contained, which will be highlighted as a Constant. This | |
4037 happens because a contained match doesn't match inside itself in the same | |
4038 position, thus the "myVim" match doesn't overrule the "myWord" match here. | |
4039 | |
4040 When you look at the colored text, it is like looking at layers of contained | |
4041 items. The contained item is on top of the item it is contained in, thus you | |
4042 see the contained item. When a contained item is transparent, you can look | |
4043 through, thus you see the item it is contained in. In a picture: | |
4044 | |
4045 look from here | |
4046 | |
4047 | | | | | | | |
4048 V V V V V V | |
4049 | |
4050 xxxx yyy more contained items | |
4051 .................... contained item (transparent) | |
4052 ============================= first item | |
4053 | |
4054 The 'x', 'y' and '=' represent a highlighted syntax item. The '.' represent a | |
4055 transparent group. | |
4056 | |
4057 What you see is: | |
4058 | |
4059 =======xxxx=======yyy======== | |
4060 | |
4061 Thus you look through the transparent "....". | |
4062 | |
4063 | |
4064 oneline *:syn-oneline* | |
4065 | |
4066 The "oneline" argument indicates that the region does not cross a line | |
4067 boundary. It must match completely in the current line. However, when the | |
4068 region has a contained item that does cross a line boundary, it continues on | |
4069 the next line anyway. A contained item can be used to recognize a line | |
4070 continuation pattern. But the "end" pattern must still match in the first | |
4071 line, otherwise the region doesn't even start. | |
4072 | |
4073 When the start pattern includes a "\n" to match an end-of-line, the end | |
4074 pattern must be found in the same line as where the start pattern ends. The | |
4075 end pattern may also include an end-of-line. Thus the "oneline" argument | |
4076 means that the end of the start pattern and the start of the end pattern must | |
4077 be within one line. This can't be changed by a skip pattern that matches a | |
4078 line break. | |
4079 | |
4080 | |
4081 fold *:syn-fold* | |
4082 | |
1624 | 4083 The "fold" argument makes the fold level increase by one for this item. |
7 | 4084 Example: > |
4085 :syn region myFold start="{" end="}" transparent fold | |
4086 :syn sync fromstart | |
4087 :set foldmethod=syntax | |
4088 This will make each {} block form one fold. | |
4089 | |
4090 The fold will start on the line where the item starts, and end where the item | |
4091 ends. If the start and end are within the same line, there is no fold. | |
4092 The 'foldnestmax' option limits the nesting of syntax folds. | |
4093 {not available when Vim was compiled without |+folding| feature} | |
4094 | |
4095 | |
4096 *:syn-contains* *E405* *E406* *E407* *E408* *E409* | |
6259 | 4097 contains={group-name},.. |
7 | 4098 |
4099 The "contains" argument is followed by a list of syntax group names. These | |
4100 groups will be allowed to begin inside the item (they may extend past the | |
4101 containing group's end). This allows for recursive nesting of matches and | |
4102 regions. If there is no "contains" argument, no groups will be contained in | |
4103 this item. The group names do not need to be defined before they can be used | |
4104 here. | |
4105 | |
4106 contains=ALL | |
4107 If the only item in the contains list is "ALL", then all | |
4108 groups will be accepted inside the item. | |
4109 | |
4110 contains=ALLBUT,{group-name},.. | |
4111 If the first item in the contains list is "ALLBUT", then all | |
4112 groups will be accepted inside the item, except the ones that | |
4113 are listed. Example: > | |
4114 :syntax region Block start="{" end="}" ... contains=ALLBUT,Function | |
4115 | |
4116 contains=TOP | |
4117 If the first item in the contains list is "TOP", then all | |
4118 groups will be accepted that don't have the "contained" | |
4119 argument. | |
4120 contains=TOP,{group-name},.. | |
4121 Like "TOP", but excluding the groups that are listed. | |
4122 | |
4123 contains=CONTAINED | |
4124 If the first item in the contains list is "CONTAINED", then | |
4125 all groups will be accepted that have the "contained" | |
4126 argument. | |
4127 contains=CONTAINED,{group-name},.. | |
4128 Like "CONTAINED", but excluding the groups that are | |
4129 listed. | |
4130 | |
4131 | |
4132 The {group-name} in the "contains" list can be a pattern. All group names | |
4133 that match the pattern will be included (or excluded, if "ALLBUT" is used). | |
4134 The pattern cannot contain white space or a ','. Example: > | |
4135 ... contains=Comment.*,Keyw[0-3] | |
4136 The matching will be done at moment the syntax command is executed. Groups | |
4137 that are defined later will not be matched. Also, if the current syntax | |
4138 command defines a new group, it is not matched. Be careful: When putting | |
4139 syntax commands in a file you can't rely on groups NOT being defined, because | |
4140 the file may have been sourced before, and ":syn clear" doesn't remove the | |
4141 group names. | |
4142 | |
4143 The contained groups will also match in the start and end patterns of a | |
4144 region. If this is not wanted, the "matchgroup" argument can be used | |
4145 |:syn-matchgroup|. The "ms=" and "me=" offsets can be used to change the | |
4146 region where contained items do match. Note that this may also limit the | |
4147 area that is highlighted | |
4148 | |
4149 | |
6259 | 4150 containedin={group-name}... *:syn-containedin* |
7 | 4151 |
4152 The "containedin" argument is followed by a list of syntax group names. The | |
4153 item will be allowed to begin inside these groups. This works as if the | |
4154 containing item has a "contains=" argument that includes this item. | |
4155 | |
6259 | 4156 The {group-name}... can be used just like for "contains", as explained above. |
7 | 4157 |
4158 This is useful when adding a syntax item afterwards. An item can be told to | |
4159 be included inside an already existing item, without changing the definition | |
4160 of that item. For example, to highlight a word in a C comment after loading | |
4161 the C syntax: > | |
4162 :syn keyword myword HELP containedin=cComment contained | |
4163 Note that "contained" is also used, to avoid that the item matches at the top | |
4164 level. | |
4165 | |
4166 Matches for "containedin" are added to the other places where the item can | |
4167 appear. A "contains" argument may also be added as usual. Don't forget that | |
4168 keywords never contain another item, thus adding them to "containedin" won't | |
4169 work. | |
4170 | |
4171 | |
6259 | 4172 nextgroup={group-name},.. *:syn-nextgroup* |
7 | 4173 |
4174 The "nextgroup" argument is followed by a list of syntax group names, | |
4175 separated by commas (just like with "contains", so you can also use patterns). | |
4176 | |
4177 If the "nextgroup" argument is given, the mentioned syntax groups will be | |
4178 tried for a match, after the match or region ends. If none of the groups have | |
4179 a match, highlighting continues normally. If there is a match, this group | |
4180 will be used, even when it is not mentioned in the "contains" field of the | |
4181 current group. This is like giving the mentioned group priority over all | |
4182 other groups. Example: > | |
4183 :syntax match ccFoobar "Foo.\{-}Bar" contains=ccFoo | |
4184 :syntax match ccFoo "Foo" contained nextgroup=ccFiller | |
4185 :syntax region ccFiller start="." matchgroup=ccBar end="Bar" contained | |
4186 | |
4187 This will highlight "Foo" and "Bar" differently, and only when there is a | |
4188 "Bar" after "Foo". In the text line below, "f" shows where ccFoo is used for | |
4189 highlighting, and "bbb" where ccBar is used. > | |
4190 | |
4191 Foo asdfasd Bar asdf Foo asdf Bar asdf | |
4192 fff bbb fff bbb | |
4193 | |
4194 Note the use of ".\{-}" to skip as little as possible until the next Bar. | |
4195 when ".*" would be used, the "asdf" in between "Bar" and "Foo" would be | |
4196 highlighted according to the "ccFoobar" group, because the ccFooBar match | |
4197 would include the first "Foo" and the last "Bar" in the line (see |pattern|). | |
4198 | |
4199 | |
4200 skipwhite *:syn-skipwhite* | |
4201 skipnl *:syn-skipnl* | |
4202 skipempty *:syn-skipempty* | |
4203 | |
4204 These arguments are only used in combination with "nextgroup". They can be | |
4205 used to allow the next group to match after skipping some text: | |
1275 | 4206 skipwhite skip over space and tab characters |
7 | 4207 skipnl skip over the end of a line |
4208 skipempty skip over empty lines (implies a "skipnl") | |
4209 | |
4210 When "skipwhite" is present, the white space is only skipped if there is no | |
4211 next group that matches the white space. | |
4212 | |
4213 When "skipnl" is present, the match with nextgroup may be found in the next | |
4214 line. This only happens when the current item ends at the end of the current | |
4215 line! When "skipnl" is not present, the nextgroup will only be found after | |
4216 the current item in the same line. | |
4217 | |
4218 When skipping text while looking for a next group, the matches for other | |
4219 groups are ignored. Only when no next group matches, other items are tried | |
4220 for a match again. This means that matching a next group and skipping white | |
4221 space and <EOL>s has a higher priority than other items. | |
4222 | |
4223 Example: > | |
4224 :syn match ifstart "\<if.*" nextgroup=ifline skipwhite skipempty | |
4225 :syn match ifline "[^ \t].*" nextgroup=ifline skipwhite skipempty contained | |
4226 :syn match ifline "endif" contained | |
4227 Note that the "[^ \t].*" match matches all non-white text. Thus it would also | |
4228 match "endif". Therefore the "endif" match is put last, so that it takes | |
4229 precedence. | |
4230 Note that this example doesn't work for nested "if"s. You need to add | |
4231 "contains" arguments to make that work (omitted for simplicity of the | |
4232 example). | |

15194 | 4248 8. Syntax patterns *:syn-pattern* *E401* *E402* |
7 | 4249 |
4250 In the syntax commands, a pattern must be surrounded by two identical | |
4251 characters. This is like it works for the ":s" command. The most common to | |
4252 use is the double quote. But if the pattern contains a double quote, you can | |
4253 use another character that is not used in the pattern. Examples: > | |
4254 :syntax region Comment start="/\*" end="\*/" | |
4255 :syntax region String start=+"+ end=+"+ skip=+\\"+ | |
4256 | |
4257 See |pattern| for the explanation of what a pattern is. Syntax patterns are | |
1624 | 4258 always interpreted like the 'magic' option is set, no matter what the actual |
7 | 4259 value of 'magic' is. And the patterns are interpreted like the 'l' flag is |
4260 not included in 'cpoptions'. This was done to make syntax files portable and | |
4261 independent of 'compatible' and 'magic' settings. | |
4262 | |
4263 Try to avoid patterns that can match an empty string, such as "[a-z]*". | |
4264 This slows down the highlighting a lot, because it matches everywhere. | |
4265 | |
4266 *:syn-pattern-offset* | |
4267 The pattern can be followed by a character offset. This can be used to | |
4268 change the highlighted part, and to change the text area included in the | |
4269 match or region (which only matters when trying to match other items). Both | |
4270 are relative to the matched pattern. The character offset for a skip | |
4271 pattern can be used to tell where to continue looking for an end pattern. | |
4272 | |
4273 The offset takes the form of "{what}={offset}" | |
4274 The {what} can be one of seven strings: | |
4275 | |
4276 ms Match Start offset for the start of the matched text | |
4277 me Match End offset for the end of the matched text | |
4278 hs Highlight Start offset for where the highlighting starts | |
4279 he Highlight End offset for where the highlighting ends | |
4280 rs Region Start offset for where the body of a region starts | |
4281 re Region End offset for where the body of a region ends | |
4282 lc Leading Context offset past "leading context" of pattern | |
4283 | |
4284 The {offset} can be: | |
4285 | |
4286 s start of the matched pattern | |
4287 s+{nr} start of the matched pattern plus {nr} chars to the right | |
4288 s-{nr} start of the matched pattern plus {nr} chars to the left | |
4289 e end of the matched pattern | |
4290 e+{nr} end of the matched pattern plus {nr} chars to the right | |
4291 e-{nr} end of the matched pattern plus {nr} chars to the left | |
4229 | 4292 {nr} (for "lc" only): start matching {nr} chars right of the start |
7 | 4293 |
4294 Examples: "ms=s+1", "hs=e-2", "lc=3". | |
4295 | |
4296 Although all offsets are accepted after any pattern, they are not always | |
4297 meaningful. This table shows which offsets are actually used: | |
4298 | |
4299 ms me hs he rs re lc ~ | |
4300 match item yes yes yes yes - - yes | |
4301 region item start yes - yes - yes - yes | |
4302 region item skip - yes - - - - yes | |
4303 region item end - yes - yes - yes yes | |
4304 | |
4305 Offsets can be concatenated, with a ',' in between. Example: > | |
4306 :syn match String /"[^"]*"/hs=s+1,he=e-1 | |
4307 < | |
4308 some "string" text | |
4309 ^^^^^^ highlighted | |
4310 | |
4311 Notes: | |
4312 - There must be no white space between the pattern and the character | |
4313 offset(s). | |
4314 - The highlighted area will never be outside of the matched text. | |
4315 - A negative offset for an end pattern may not always work, because the end | |
4316 pattern may be detected when the highlighting should already have stopped. | |

4319 Vim 7.2 release. |
7 | 4320 - The start of a match cannot be in a line other than where the pattern |
4321 matched. This doesn't work: "a\nb"ms=e. You can make the highlighting | |
4322 start in another line, this does work: "a\nb"hs=e. | |
4323 | |
4324 Example (match a comment but don't highlight the /* and */): > | |
4325 :syntax region Comment start="/\*"hs=e+1 end="\*/"he=s-1 | |
4326 < | |
4327 /* this is a comment */ | |
4328 ^^^^^^^^^^^^^^^^^^^ highlighted | |

4330 A more complicated Example: > | |
4331 :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 | |
4332 < | |
4333 abcfoostringbarabc | |
4334 mmmmmmmmmmm match | |
625 | 4335 sssrrreee highlight start/region/end ("Foo", "Exa" and "Bar") |
7 | 4336 |
4337 Leading context *:syn-lc* *:syn-leading* *:syn-context* | |
4338 | |
4339 Note: This is an obsolete feature, only included for backwards compatibility | |
4340 with previous Vim versions. It's now recommended to use the |/\@<=| construct | |
4341 in the pattern. | |
4342 | |
4343 The "lc" offset specifies leading context -- a part of the pattern that must | |
4344 be present, but is not considered part of the match. An offset of "lc=n" will | |
4345 cause Vim to step back n columns before attempting the pattern match, allowing | |
4346 characters which have already been matched in previous patterns to also be | |
4347 used as leading context for this match. This can be used, for instance, to | |
4348 specify that an "escaping" character must not precede the match: > | |
4349 | |
4350 :syn match ZNoBackslash "[^\\]z"ms=s+1 | |
4351 :syn match WNoBackslash "[^\\]w"lc=1 | |
4352 :syn match Underline "_\+" | |
4353 < | |
4354 ___zzzz ___wwww | |
4355 ^^^ ^^^ matches Underline | |
4356 ^ ^ matches ZNoBackslash | |
4357 ^^^^ matches WNoBackslash | |
4358 | |
4359 The "ms" offset is automatically set to the same value as the "lc" offset, | |
4360 unless you set "ms" explicitly. | |
4361 | |
4362 | |
4363 Multi-line patterns *:syn-multi-line* | |
4364 | |
4365 The patterns can include "\n" to match an end-of-line. Mostly this works as | |
4366 expected, but there are a few exceptions. | |
4367 | |
4368 When using a start pattern with an offset, the start of the match is not | |
4369 allowed to start in a following line. The highlighting can start in a | |

4371 the match doesn't move to another line. |
7 | 4372 |
4373 The skip pattern can include the "\n", but the search for an end pattern will | |
4374 continue in the first character of the next line, also when that character is | |
4375 matched by the skip pattern. This is because redrawing may start in any line | |
4376 halfway a region and there is no check if the skip pattern started in a | |
4377 previous line. For example, if the skip pattern is "a\nb" and an end pattern | |
4378 is "b", the end pattern does match in the second line of this: > | |
4379 x x a | |
4380 b x x | |
4381 Generally this means that the skip pattern should not match any characters | |
4382 after the "\n". | |
4383 | |
4384 | |
4385 External matches *:syn-ext-match* | |
4386 | |
4387 These extra regular expression items are available in region patterns: | |
4388 | |
4780 | 4389 */\z(* */\z(\)* *E50* *E52* *E879* |
4073 | 4390 \z(\) Marks the sub-expression as "external", meaning that it can be |
4391 accessed from another pattern match. Currently only usable in | |
4392 defining a syntax region start pattern. | |
7 | 4393 |
4394 */\z1* */\z2* */\z3* */\z4* */\z5* | |
4395 \z1 ... \z9 */\z6* */\z7* */\z8* */\z9* *E66* *E67* | |
4396 Matches the same string that was matched by the corresponding | |
4397 sub-expression in a previous start pattern match. | |
4398 | |
4399 Sometimes the start and end patterns of a region need to share a common | |
4400 sub-expression. A common example is the "here" document in Perl and many Unix | |
4401 shells. This effect can be achieved with the "\z" special regular expression | |
4402 items, which marks a sub-expression as "external", in the sense that it can be | |
4403 referenced from outside the pattern in which it is defined. The here-document | |
4404 example, for instance, can be done like this: > | |
4405 :syn region hereDoc start="<<\z(\I\i*\)" end="^\z1$" | |
4406 | |
4407 As can be seen here, the \z actually does double duty. In the start pattern, | |
4408 it marks the "\(\I\i*\)" sub-expression as external; in the end pattern, it | |

4409 changes the \z1 back-reference into an external reference referring to the |
7 | 4410 first external sub-expression in the start pattern. External references can |
4411 also be used in skip patterns: > | |
4412 :syn region foo start="start \(\I\i*\)" skip="not end \z1" end="end \z1" | |
4413 | |
4414 Note that normal and external sub-expressions are completely orthogonal and | |
4415 indexed separately; for instance, if the pattern "\z(..\)\(..\)" is applied | |
4416 to the string "aabb", then \1 will refer to "bb" and \z1 will refer to "aa". | |
4417 Note also that external sub-expressions cannot be accessed as back-references | |
4418 within the same pattern like normal sub-expressions. If you want to use one | |
4419 sub-expression as both a normal and an external sub-expression, you can nest | |
4420 the two, as in "\(\z(...\)\)". | |
4421 | |
4422 Note that only matches within a single line can be used. Multi-line matches | |
4423 cannot be referred to. | |

4425 ============================================================================== | |
15194 | 4426 9. Syntax clusters *:syn-cluster* *E400* |
7 | 4427 |
4428 :sy[ntax] cluster {cluster-name} [contains={group-name}..] | |
4429 [add={group-name}..] | |
4430 [remove={group-name}..] | |
4431 | |
4432 This command allows you to cluster a list of syntax groups together under a | |
4433 single name. | |
4434 | |
4435 contains={group-name}.. | |
4436 The cluster is set to the specified list of groups. | |
4437 add={group-name}.. | |
4438 The specified groups are added to the cluster. | |
4439 remove={group-name}.. | |
4440 The specified groups are removed from the cluster. | |
4441 | |
1624 | 4442 A cluster so defined may be referred to in a contains=.., containedin=.., |
4443 nextgroup=.., add=.. or remove=.. list with a "@" prefix. You can also use | |
4444 this notation to implicitly declare a cluster before specifying its contents. | |
7 | 4445 |
4446 Example: > | |
4447 :syntax match Thing "# [^#]\+ #" contains=@ThingMembers | |
4448 :syntax cluster ThingMembers contains=ThingMember1,ThingMember2 | |
4449 | |
4450 As the previous example suggests, modifications to a cluster are effectively | |
4451 retroactive; the membership of the cluster is checked at the last minute, so | |
4452 to speak: > | |
4453 :syntax keyword A aaa | |
4454 :syntax keyword B bbb | |
4455 :syntax cluster AandB contains=A | |
4456 :syntax match Stuff "( aaa bbb )" contains=@AandB | |
4457 :syntax cluster AandB add=B " now both keywords are matched in Stuff | |
4458 | |
4459 This also has implications for nested clusters: > | |
4460 :syntax keyword A aaa | |
4461 :syntax keyword B bbb | |
4462 :syntax cluster SmallGroup contains=B | |
4463 :syntax cluster BigGroup contains=A,@SmallGroup | |
4464 :syntax match Stuff "( aaa bbb )" contains=@BigGroup | |
4465 :syntax cluster BigGroup remove=B " no effect, since B isn't in BigGroup | |
4466 :syntax cluster SmallGroup remove=B " now bbb isn't matched within Stuff | |
2751 | 4467 < |
4468 *E848* | |
4469 The maximum number of clusters is 9767. | |
7 | 4470 |
4471 ============================================================================== | |
15194 | 4472 10. Including syntax files *:syn-include* *E397* |
7 | 4473 |
4474 It is often useful for one language's syntax file to include a syntax file for | |
4475 a related language. Depending on the exact relationship, this can be done in | |
4476 two different ways: | |
4477 | |
4478 - If top-level syntax items in the included syntax file are to be | |
4479 allowed at the top level in the including syntax, you can simply use | |
4480 the |:runtime| command: > | |
4481 | |
4482 " In cpp.vim: | |
4483 :runtime! syntax/c.vim | |
4484 :unlet b:current_syntax | |
4485 | |
4486 < - If top-level syntax items in the included syntax file are to be | |
4487 contained within a region in the including syntax, you can use the | |
4488 ":syntax include" command: | |
4489 | |
4490 :sy[ntax] include [@{grouplist-name}] {file-name} | |
4491 | |
4492 All syntax items declared in the included file will have the | |
4493 "contained" flag added. In addition, if a group list is specified, | |
4494 all top-level syntax items in the included file will be added to | |
4495 that list. > | |
4496 | |
4497 " In perl.vim: | |
4498 :syntax include @Pod <sfile>:p:h/pod.vim | |
4499 :syntax region perlPOD start="^=head" end="^=cut" contains=@Pod | |
4500 < | |
4501 When {file-name} is an absolute path (starts with "/", "c:", "$VAR" | |
4502 or "<sfile>") that file is sourced. When it is a relative path | |
4503 (e.g., "syntax/pod.vim") the file is searched for in 'runtimepath'. | |
4504 All matching files are loaded. Using a relative path is | |
4505 recommended, because it allows a user to replace the included file | |
4506 with his own version, without replacing the file that does the ":syn | |
4507 include". | |
4508 | |
2751 | 4509 *E847* |
4510 The maximum number of includes is 999. | |
4511 | |
7 | 4512 ============================================================================== |
15194 | 4513 11. Synchronizing *:syn-sync* *E403* *E404* |
7 | 4514 |
4515 Vim wants to be able to start redrawing in any position in the document. To | |
4516 make this possible it needs to know the syntax state at the position where | |
4517 redrawing starts. | |
4518 | |
4519 :sy[ntax] sync [ccomment [group-name] | minlines={N} | ...] | |
4520 | |
4521 There are four ways to synchronize: | |
4522 1. Always parse from the start of the file. | |
4523 |:syn-sync-first| | |
4524 2. Based on C-style comments. Vim understands how C-comments work and can | |
4525 figure out if the current line starts inside or outside a comment. | |
4526 |:syn-sync-second| | |
4527 3. Jumping back a certain number of lines and start parsing there. | |
4528 |:syn-sync-third| | |
4529 4. Searching backwards in the text for a pattern to sync on. | |
4530 |:syn-sync-fourth| | |
4531 | |
4532 *:syn-sync-maxlines* *:syn-sync-minlines* | |
4533 For the last three methods, the line range where the parsing can start is | |
4534 limited by "minlines" and "maxlines". | |
4535 | |
4536 If the "minlines={N}" argument is given, the parsing always starts at least | |
4537 that many lines backwards. This can be used if the parsing may take a few | |
4538 lines before it's correct, or when it's not possible to use syncing. | |
4539 | |
4540 If the "maxlines={N}" argument is given, the number of lines that are searched | |
4541 for a comment or syncing pattern is restricted to N lines backwards (after | |
4542 adding "minlines"). This is useful if you have few things to sync on and a | |
4543 slow machine. Example: > | |
6647 | 4544 :syntax sync maxlines=500 ccomment |
7 | 4545 < |
4546 *:syn-sync-linebreaks* | |
4547 When using a pattern that matches multiple lines, a change in one line may | |
4548 cause a pattern to no longer match in a previous line. This means has to | |
4549 start above where the change was made. How many lines can be specified with | |
4550 the "linebreaks" argument. For example, when a pattern may include one line | |
4551 break use this: > | |
4552 :syntax sync linebreaks=1 | |
4553 The result is that redrawing always starts at least one line before where a | |
4554 change was made. The default value for "linebreaks" is zero. Usually the | |
4555 value for "minlines" is bigger than "linebreaks". | |
4556 | |
4557 | |
4558 First syncing method: *:syn-sync-first* | |
4559 > | |
4560 :syntax sync fromstart | |
4561 | |
4562 The file will be parsed from the start. This makes syntax highlighting | |
4563 accurate, but can be slow for long files. Vim caches previously parsed text, | |
4564 so that it's only slow when parsing the text for the first time. However, | |
3224 | 4565 when making changes some part of the text needs to be parsed again (worst |
7 | 4566 case: to the end of the file). |
4567 | |
4568 Using "fromstart" is equivalent to using "minlines" with a very large number. | |
4569 | |
4570 | |
4571 Second syncing method: *:syn-sync-second* *:syn-sync-ccomment* | |
4572 | |
4573 For the second method, only the "ccomment" argument needs to be given. | |
4574 Example: > | |
4575 :syntax sync ccomment | |
4576 | |
4577 When Vim finds that the line where displaying starts is inside a C-style | |
4578 comment, the last region syntax item with the group-name "Comment" will be | |
4579 used. This requires that there is a region with the group-name "Comment"! | |
4580 An alternate group name can be specified, for example: > | |
4581 :syntax sync ccomment javaComment | |
4582 This means that the last item specified with "syn region javaComment" will be | |
4583 used for the detected C comment region. This only works properly if that | |
4584 region does have a start pattern "\/*" and an end pattern "*\/". | |
4585 | |
4586 The "maxlines" argument can be used to restrict the search to a number of | |
4587 lines. The "minlines" argument can be used to at least start a number of | |
4588 lines back (e.g., for when there is some construct that only takes a few | |
4589 lines, but it hard to sync on). | |
4590 | |
4591 Note: Syncing on a C comment doesn't work properly when strings are used | |
4592 that cross a line and contain a "*/". Since letting strings cross a line | |
4593 is a bad programming habit (many compilers give a warning message), and the | |
4594 chance of a "*/" appearing inside a comment is very small, this restriction | |
4595 is hardly ever noticed. | |
4596 | |
4597 | |
4598 Third syncing method: *:syn-sync-third* | |
4599 | |
4600 For the third method, only the "minlines={N}" argument needs to be given. | |
4601 Vim will subtract {N} from the line number and start parsing there. This | |
4602 means {N} extra lines need to be parsed, which makes this method a bit slower. | |
4603 Example: > | |
4604 :syntax sync minlines=50 | |
4605 | |
4606 "lines" is equivalent to "minlines" (used by older versions). | |
4607 | |
4608 | |
4609 Fourth syncing method: *:syn-sync-fourth* | |
4610 | |
4611 The idea is to synchronize on the end of a few specific regions, called a | |
4612 sync pattern. Only regions can cross lines, so when we find the end of some | |
4613 region, we might be able to know in which syntax item we are. The search | |
4614 starts in the line just above the one where redrawing starts. From there | |
4615 the search continues backwards in the file. | |
4616 | |
4617 This works just like the non-syncing syntax items. You can use contained | |
4618 matches, nextgroup, etc. But there are a few differences: | |
4619 - Keywords cannot be used. | |
4620 - The syntax items with the "sync" keyword form a completely separated group | |
4621 of syntax items. You can't mix syncing groups and non-syncing groups. | |
4622 - The matching works backwards in the buffer (line by line), instead of | |
4623 forwards. | |
4624 - A line continuation pattern can be given. It is used to decide which group | |
4625 of lines need to be searched like they were one line. This means that the | |
4626 search for a match with the specified items starts in the first of the | |
4627 consecutive that contain the continuation pattern. | |
4628 - When using "nextgroup" or "contains", this only works within one line (or | |
4629 group of continued lines). | |
4630 - When using a region, it must start and end in the same line (or group of | |
4631 continued lines). Otherwise the end is assumed to be at the end of the | |
4632 line (or group of continued lines). | |
4633 - When a match with a sync pattern is found, the rest of the line (or group of | |
4634 continued lines) is searched for another match. The last match is used. | |
4635 This is used when a line can contain both the start end the end of a region | |
4636 (e.g., in a C-comment like /* this */, the last "*/" is used). | |
4637 | |
4638 There are two ways how a match with a sync pattern can be used: | |
4639 1. Parsing for highlighting starts where redrawing starts (and where the | |
4640 search for the sync pattern started). The syntax group that is expected | |
4641 to be valid there must be specified. This works well when the regions | |
4642 that cross lines cannot contain other regions. | |
4643 2. Parsing for highlighting continues just after the match. The syntax group | |
4644 that is expected to be present just after the match must be specified. | |
4645 This can be used when the previous method doesn't work well. It's much | |
4646 slower, because more text needs to be parsed. | |
4647 Both types of sync patterns can be used at the same time. | |
4648 | |
4649 Besides the sync patterns, other matches and regions can be specified, to | |
4650 avoid finding unwanted matches. | |
4651 | |
4652 [The reason that the sync patterns are given separately, is that mostly the | |
4653 search for the sync point can be much simpler than figuring out the | |
4654 highlighting. The reduced number of patterns means it will go (much) | |
4655 faster.] | |
4656 | |
4657 *syn-sync-grouphere* *E393* *E394* | |
4658 :syntax sync match {sync-group-name} grouphere {group-name} "pattern" .. | |
4659 | |
4660 Define a match that is used for syncing. {group-name} is the | |
4661 name of a syntax group that follows just after the match. Parsing | |
4662 of the text for highlighting starts just after the match. A region | |
4663 must exist for this {group-name}. The first one defined will be used. | |
4664 "NONE" can be used for when there is no syntax group after the match. | |
4665 | |
4666 *syn-sync-groupthere* | |
4667 :syntax sync match {sync-group-name} groupthere {group-name} "pattern" .. | |
4668 | |
4669 Like "grouphere", but {group-name} is the name of a syntax group that | |
4670 is to be used at the start of the line where searching for the sync | |
4671 point started. The text between the match and the start of the sync | |
4672 pattern searching is assumed not to change the syntax highlighting. | |
4673 For example, in C you could search backwards for "/*" and "*/". If | |
4674 "/*" is found first, you know that you are inside a comment, so the | |
4675 "groupthere" is "cComment". If "*/" is found first, you know that you | |
4676 are not in a comment, so the "groupthere" is "NONE". (in practice | |
4677 it's a bit more complicated, because the "/*" and "*/" could appear | |
4678 inside a string. That's left as an exercise to the reader...). | |
4679 | |
4680 :syntax sync match .. | |
4681 :syntax sync region .. | |
4682 | |
4683 Without a "groupthere" argument. Define a region or match that is | |
4684 skipped while searching for a sync point. | |
4685 | |
856 | 4686 *syn-sync-linecont* |
7 | 4687 :syntax sync linecont {pattern} |
4688 | |
4689 When {pattern} matches in a line, it is considered to continue in | |
4690 the next line. This means that the search for a sync point will | |
4691 consider the lines to be concatenated. | |
4692 | |
4693 If the "maxlines={N}" argument is given too, the number of lines that are | |
4694 searched for a match is restricted to N. This is useful if you have very | |
4695 few things to sync on and a slow machine. Example: > | |
4696 :syntax sync maxlines=100 | |
4697 | |
4698 You can clear all sync settings with: > | |
4699 :syntax sync clear | |
4700 | |
4701 You can clear specific sync patterns with: > | |
4702 :syntax sync clear {sync-group-name} .. | |
4703 | |
4704 ============================================================================== | |
15194 | 4705 12. Listing syntax items *:syntax* *:sy* *:syn* *:syn-list* |
7 | 4706 |
534 | 4707 This command lists all the syntax items: > |
7 | 4708 |
4709 :sy[ntax] [list] | |
4710 | |
4711 To show the syntax items for one syntax group: > | |
4712 | |
4713 :sy[ntax] list {group-name} | |
4714 | |
2581 | 4715 To list the syntax groups in one cluster: *E392* > |
7 | 4716 |
4717 :sy[ntax] list @{cluster-name} | |
4718 | |
4719 See above for other arguments for the ":syntax" command. | |
4720 | |
4721 Note that the ":syntax" command can be abbreviated to ":sy", although ":syn" | |
4722 is mostly used, because it looks better. | |
4723 | |
4724 ============================================================================== | |
15194 | 4725 13. Highlight command *:highlight* *:hi* *E28* *E411* *E415* |
7 | 4726 |
4727 There are three types of highlight groups: | |
4728 - The ones used for specific languages. For these the name starts with the | |
4729 name of the language. Many of these don't have any attributes, but are | |
4730 linked to a group of the second type. | |
4731 - The ones used for all syntax languages. | |
4732 - The ones used for the 'highlight' option. | |
4733 *hitest.vim* | |
4734 You can see all the groups currently active with this command: > | |
4735 :so $VIMRUNTIME/syntax/hitest.vim | |
4736 This will open a new window containing all highlight group names, displayed | |
4737 in their own color. | |
4738 | |
4739 *:colo* *:colorscheme* *E185* | |
2152 | 4740 :colo[rscheme] Output the name of the currently active color scheme. |
4741 This is basically the same as > | |
4742 :echo g:colors_name | |
4743 < In case g:colors_name has not been defined :colo will | |
4744 output "default". When compiled without the |+eval| | |
4745 feature it will output "unknown". | |
4746 | |
7 | 4747 :colo[rscheme] {name} Load color scheme {name}. This searches 'runtimepath' |

4771 | |
4772 :hi[ghlight] {group-name} | |
4773 List one highlight group. | |
4774 | |
4775 :hi[ghlight] clear Reset all highlighting to the defaults. Removes all | |
4776 highlighting for groups added by the user! | |
4777 Uses the current value of 'background' to decide which | |
4778 default colors to use. | |
4779 | |
4780 :hi[ghlight] clear {group-name} | |
4781 :hi[ghlight] {group-name} NONE | |
4782 Disable the highlighting for one highlight group. It | |
4783 is _not_ set back to the default colors. | |
4784 | |
4785 :hi[ghlight] [default] {group-name} {key}={arg} .. | |
4786 Add a highlight group, or change the highlighting for | |
4787 an existing group. | |
4788 See |highlight-args| for the {key}={arg} arguments. | |
4789 See |:highlight-default| for the optional [default] | |
4790 argument. | |
4791 | |
4792 Normally a highlight group is added once when starting up. This sets the | |
4793 default values for the highlighting. After that, you can use additional | |
4794 highlight commands to change the arguments that you want to set to non-default | |
4795 values. The value "NONE" can be used to switch the value off or go back to | |
4796 the default value. | |
4797 | |
4798 A simple way to change colors is with the |:colorscheme| command. This loads | |
4799 a file with ":highlight" commands such as this: > | |
4800 | |
4801 :hi Comment gui=bold | |
4802 | |
4803 Note that all settings that are not included remain the same, only the | |
4804 specified field is used, and settings are merged with previous ones. So, the | |
4805 result is like this single command has been used: > | |
4806 :hi Comment term=bold ctermfg=Cyan guifg=#80a0ff gui=bold | |
4807 < | |
856 | 4808 *:highlight-verbose* |
448 | 4809 When listing a highlight group and 'verbose' is non-zero, the listing will |
4810 also tell where it was last set. Example: > | |
4811 :verbose hi Comment | |
4812 < Comment xxx term=bold ctermfg=4 guifg=Blue ~ | |
856 | 4813 Last set from /home/mool/vim/vim7/runtime/syntax/syncolor.vim ~ |
448 | 4814 |
484 | 4815 When ":hi clear" is used then the script where this command is used will be |
4816 mentioned for the default values. See |:verbose-cmd| for more information. | |
448 | 4817 |
7 | 4818 *highlight-args* *E416* *E417* *E423* |
4819 There are three types of terminals for highlighting: | |
4820 term a normal terminal (vt100, xterm) | |
4821 cterm a color terminal (MS-DOS console, color-xterm, these have the "Co" | |
4822 termcap entry) | |
4823 gui the GUI | |
4824 | |
4825 For each type the highlighting can be given. This makes it possible to use | |
4826 the same syntax file on all terminals, and use the optimal highlighting. | |

4851 is only available in the GUI. The color is set with |highlight-guisp|. |
7 | 4852 |
4853 start={term-list} *highlight-start* *E422* | |
4854 stop={term-list} *term-list* *highlight-stop* | |
4855 These lists of terminal codes can be used to get | |
4856 non-standard attributes on a terminal. | |
4857 | |
4858 The escape sequence specified with the "start" argument | |
4859 is written before the characters in the highlighted | |
4860 area. It can be anything that you want to send to the | |
4861 terminal to highlight this area. The escape sequence | |
4862 specified with the "stop" argument is written after the | |
4863 highlighted area. This should undo the "start" argument. | |
4864 Otherwise the screen will look messed up. | |
4865 | |
4866 The {term-list} can have two forms: | |
4867 | |
4868 1. A string with escape sequences. | |
4869 This is any string of characters, except that it can't start with | |
4870 "t_" and blanks are not allowed. The <> notation is recognized | |
4871 here, so you can use things like "<Esc>" and "<Space>". Example: | |
4872 start=<Esc>[27h;<Esc>[<Space>r; | |
4873 | |
4874 2. A list of terminal codes. | |
4875 Each terminal code has the form "t_xx", where "xx" is the name of | |
4876 the termcap entry. The codes have to be separated with commas. | |
4877 White space is not allowed. Example: | |
4878 start=t_C1,t_BL | |
4879 The terminal codes must exist for this to work. | |
4880 | |
4881 | |
4882 2. highlight arguments for color terminals | |
4883 | |
4884 cterm={attr-list} *highlight-cterm* | |
4885 See above for the description of {attr-list} |attr-list|. | |
4886 The "cterm" argument is likely to be different from "term", when | |
4887 colors are used. For example, in a normal terminal comments could | |
4888 be underlined, in a color terminal they can be made Blue. | |
16808 | 4889 Note: Some terminals (e.g., DOS console) can't mix these attributes |
4890 with coloring. To be portable, use only one of "cterm=" OR "ctermfg=" | |
4891 OR "ctermbg=". | |
7 | 4892 |
4893 ctermfg={color-nr} *highlight-ctermfg* *E421* | |
4894 ctermbg={color-nr} *highlight-ctermbg* | |
4895 The {color-nr} argument is a color number. Its range is zero to | |
4896 (not including) the number given by the termcap entry "Co". | |
4897 The actual color with this number depends on the type of terminal | |
4898 and its settings. Sometimes the color also depends on the settings of | |
4899 "cterm". For example, on some systems "cterm=bold ctermfg=3" gives | |
4900 another color, on others you just get color 3. | |
4901 | |
4902 For an xterm this depends on your resources, and is a bit | |
4903 unpredictable. See your xterm documentation for the defaults. The | |
4904 colors for a color-xterm can be changed from the .Xdefaults file. | |
4905 Unfortunately this means that it's not possible to get the same colors | |
4906 for each user. See |xterm-color| for info about color xterms. | |
4907 | |
4908 The MSDOS standard colors are fixed (in a console window), so these | |
4909 have been used for the names. But the meaning of color names in X11 | |
4910 are fixed, so these color settings have been used, to make the | |
4911 highlighting settings portable (complicated, isn't it?). The | |
4912 following names are recognized, with the color number used: | |
4913 | |
4914 *cterm-colors* | |
4915 NR-16 NR-8 COLOR NAME ~ | |
4916 0 0 Black | |
4917 1 4 DarkBlue | |
4918 2 2 DarkGreen | |
4919 3 6 DarkCyan | |
4920 4 1 DarkRed | |
4921 5 5 DarkMagenta | |
4922 6 3 Brown, DarkYellow | |
4923 7 7 LightGray, LightGrey, Gray, Grey | |
4924 8 0* DarkGray, DarkGrey | |
4925 9 4* Blue, LightBlue | |
4926 10 2* Green, LightGreen | |
4927 11 6* Cyan, LightCyan | |
4928 12 1* Red, LightRed | |
4929 13 5* Magenta, LightMagenta | |
4930 14 3* Yellow, LightYellow | |
4931 15 7* White | |
4932 | |
4933 The number under "NR-16" is used for 16-color terminals ('t_Co' | |
4934 greater than or equal to 16). The number under "NR-8" is used for | |
4935 8-color terminals ('t_Co' less than 16). The '*' indicates that the | |
4936 bold attribute is set for ctermfg. In many 8-color terminals (e.g., | |
4937 "linux"), this causes the bright colors to appear. This doesn't work | |
4938 for background colors! Without the '*' the bold attribute is removed. | |
4939 If you want to set the bold attribute in a different way, put a | |
4940 "cterm=" argument AFTER the "ctermfg=" or "ctermbg=" argument. Or use | |
4941 a number instead of a color name. | |
4942 | |
4943 The case of the color names is ignored. | |
4944 Note that for 16 color ansi style terminals (including xterms), the | |
237 | 4945 numbers in the NR-8 column is used. Here '*' means 'add 8' so that Blue |
7 | 4946 is 12, DarkGray is 8 etc. |
4947 | |
4948 Note that for some color terminals these names may result in the wrong | |
4949 colors! | |
4950 | |
6697 | 4951 You can also use "NONE" to remove the color. |
4952 | |
7 | 4953 *:hi-normal-cterm* |
4954 When setting the "ctermfg" or "ctermbg" colors for the Normal group, | |
4955 these will become the colors used for the non-highlighted text. | |
4956 Example: > | |
4957 :highlight Normal ctermfg=grey ctermbg=darkblue | |
4958 < When setting the "ctermbg" color for the Normal group, the | |
11473 | 4959 'background' option will be adjusted automatically, under the |
4960 condition that the color is recognized and 'background' was not set | |
4961 explicitly. This causes the highlight groups that depend on | |
4962 'background' to change! This means you should set the colors for | |
4963 Normal first, before setting other colors. | |
16208 | 4964 When a color scheme is being used, changing 'background' causes it to |
7 | 4965 be reloaded, which may reset all colors (including Normal). First |

4966 delete the "g:colors_name" variable when you don't want this. |
7 | 4967 |
4968 When you have set "ctermfg" or "ctermbg" for the Normal group, Vim | |
4969 needs to reset the color when exiting. This is done with the "op" | |
4970 termcap entry |t_op|. If this doesn't work correctly, try setting the | |
4971 't_op' option in your .vimrc. | |
4972 *E419* *E420* | |
4973 When Vim knows the normal foreground and background colors, "fg" and | |
4974 "bg" can be used as color names. This only works after setting the | |
4975 colors for the Normal group and for the MS-DOS console. Example, for | |
4976 reverse video: > | |
4977 :highlight Visual ctermfg=bg ctermbg=fg | |
4978 < Note that the colors are used that are valid at the moment this | |
4979 command are given. If the Normal group colors are changed later, the | |
4980 "fg" and "bg" colors will not be adjusted. | |
4981 | |
4982 | |
4983 3. highlight arguments for the GUI | |
4984 | |
4985 gui={attr-list} *highlight-gui* | |
4986 These give the attributes to use in the GUI mode. | |
4987 See |attr-list| for a description. | |
4988 Note that "bold" can be used here and by using a bold font. They | |
4989 have the same effect. | |
4990 Note that the attributes are ignored for the "Normal" group. | |
4991 | |
4992 font={font-name} *highlight-font* | |
4993 font-name is the name of a font, as it is used on the system Vim | |
4994 runs on. For X11 this is a complicated name, for example: > | |
4995 font=-misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1 | |
4996 < | |
4997 The font-name "NONE" can be used to revert to the default font. | |
4998 When setting the font for the "Normal" group, this becomes the default | |
4999 font (until the 'guifont' option is changed; the last one set is | |
5000 used). | |
5001 The following only works with Motif and Athena, not with other GUIs: | |
5002 When setting the font for the "Menu" group, the menus will be changed. | |
5003 When setting the font for the "Tooltip" group, the tooltips will be | |
5004 changed. | |
5005 All fonts used, except for Menu and Tooltip, should be of the same | |
5006 character size as the default font! Otherwise redrawing problems will | |
5007 occur. | |

5223 specifies a fontset at all times, no matter if 'guifontset' is | |
5224 empty, and as such it is tied to the current |:language| when | |
5225 set. | |

15194 | 5228 14. Linking groups *:hi-link* *:highlight-link* *E412* *E413* |
7 | 5229 |
5230 When you want to use the same highlighting for several syntax groups, you | |
5231 can do this more easily by linking the groups into one common highlight | |
5232 group, and give the color attributes only for that group. | |
5233 | |
5234 To set a link: | |
5235 | |
5236 :hi[ghlight][!] [default] link {from-group} {to-group} | |
5237 | |
5238 To remove a link: | |
5239 | |
5240 :hi[ghlight][!] [default] link {from-group} NONE | |
5241 | |
5242 Notes: *E414* | |
5243 - If the {from-group} and/or {to-group} doesn't exist, it is created. You | |
5244 don't get an error message for a non-existing group. | |
5245 - As soon as you use a ":highlight" command for a linked group, the link is | |
5246 removed. | |
5247 - If there are already highlight settings for the {from-group}, the link is | |
5248 not made, unless the '!' is given. For a ":highlight link" command in a | |
5249 sourced file, you don't get an error message. This can be used to skip | |
5250 links for groups that already have settings. | |
5251 | |
5252 *:hi-default* *:highlight-default* | |
5253 The [default] argument is used for setting the default highlighting for a | |
5254 group. If highlighting has already been specified for the group the command | |
5255 will be ignored. Also when there is an existing link. | |
5256 | |
5257 Using [default] is especially useful to overrule the highlighting of a | |
5258 specific syntax file. For example, the C syntax file contains: > | |
5259 :highlight default link cComment Comment | |
5260 If you like Question highlighting for C comments, put this in your vimrc file: > | |
5261 :highlight link cComment Question | |
5262 Without the "default" in the C syntax file, the highlighting would be | |
5263 overruled when the syntax file is loaded. | |
5264 | |
5265 ============================================================================== | |
15194 | 5266 15. Cleaning up *:syn-clear* *E391* |
7 | 5267 |
5268 If you want to clear the syntax stuff for the current buffer, you can use this | |
5269 command: > | |
5270 :syntax clear | |
5271 | |
5272 This command should be used when you want to switch off syntax highlighting, | |
5273 or when you want to switch to using another syntax. It's normally not needed | |
5274 in a syntax file itself, because syntax is cleared by the autocommands that | |
5275 load the syntax file. | |
5276 The command also deletes the "b:current_syntax" variable, since no syntax is | |
5277 loaded after this command. | |
5278 | |
16944 | 5279 To clean up specific syntax groups for the current buffer: > |
5280 :syntax clear {group-name} .. | |
5281 This removes all patterns and keywords for {group-name}. | |
5282 | |
5283 To clean up specific syntax group lists for the current buffer: > | |
5284 :syntax clear @{grouplist-name} .. | |
5285 This sets {grouplist-name}'s contents to an empty list. | |
5286 | |
5287 *:syntax-off* *:syn-off* | |
7 | 5288 If you want to disable syntax highlighting for all buffers, you need to remove |
5289 the autocommands that load the syntax files: > | |
5290 :syntax off | |
5291 | |
5292 What this command actually does, is executing the command > | |
5293 :source $VIMRUNTIME/syntax/nosyntax.vim | |
5294 See the "nosyntax.vim" file for details. Note that for this to work | |
5295 $VIMRUNTIME must be valid. See |$VIMRUNTIME|. | |
5296 | |
5297 *:syntax-reset* *:syn-reset* | |
5298 If you have changed the colors and messed them up, use this command to get the | |
5299 defaults back: > | |
5300 | |
5301 :syntax reset | |
5302 | |

7 | 5306 This doesn't change the colors for the 'highlight' option. |
5307 | |
5308 Note that the syntax colors that you set in your vimrc file will also be reset | |
5309 back to their Vim default. | |
5310 Note that if you are using a color scheme, the colors defined by the color | |
5311 scheme for syntax highlighting will be lost. | |
5312 | |
5313 What this actually does is: > | |
5314 | |
5315 let g:syntax_cmd = "reset" | |
5316 runtime! syntax/syncolor.vim | |
5317 | |
5318 Note that this uses the 'runtimepath' option. | |
5319 | |
5320 *syncolor* | |
5321 If you want to use different colors for syntax highlighting, you can add a Vim | |
5322 script file to set these colors. Put this file in a directory in | |
5323 'runtimepath' which comes after $VIMRUNTIME, so that your settings overrule | |
5324 the default colors. This way these colors will be used after the ":syntax | |
5325 reset" command. | |
5326 | |
5327 For Unix you can use the file ~/.vim/after/syntax/syncolor.vim. Example: > | |
5328 | |
5329 if &background == "light" | |
5330 highlight comment ctermfg=darkgreen guifg=darkgreen | |
5331 else | |
5332 highlight comment ctermfg=green guifg=green | |
5333 endif | |
5334 | |
24 | 5335 *E679* |
5336 Do make sure this syncolor.vim script does not use a "syntax on", set the | |
5337 'background' option or uses a "colorscheme" command, because it results in an | |
5338 endless loop. | |
5339 | |
7 | 5340 Note that when a color scheme is used, there might be some confusion whether |
5341 your defined colors are to be used or the colors from the scheme. This | |
5342 depends on the color scheme file. See |:colorscheme|. | |
5343 | |
5344 *syntax_cmd* | |
5345 The "syntax_cmd" variable is set to one of these values when the | |
5346 syntax/syncolor.vim files are loaded: | |
5347 "on" ":syntax on" command. Highlight colors are overruled but | |
5348 links are kept | |
5349 "enable" ":syntax enable" command. Only define colors for groups that | |
5350 don't have highlighting yet. Use ":syntax default". | |
5351 "reset" ":syntax reset" command or loading a color scheme. Define all | |
5352 the colors. | |
5353 "skip" Don't define colors. Used to skip the default settings when a | |
5354 syncolor.vim file earlier in 'runtimepath' has already set | |
5355 them. | |
5356 | |
5357 ============================================================================== | |
15194 | 5358 16. Highlighting tags *tag-highlight* |
7 | 5359 |
5360 If you want to highlight all the tags in your file, you can use the following | |
5361 mappings. | |
5362 | |
5363 <F11> -- Generate tags.vim file, and highlight tags. | |
5364 <F12> -- Just highlight tags based on existing tags.vim file. | |
5365 > | |
5366 :map <F11> :sp tags<CR>:%s/^\([^ :]*:\)\=\([^ ]*\).*/syntax keyword Tag \2/<CR>:wq! tags.vim<CR>/^<CR><F12> | |
5367 :map <F12> :so tags.vim<CR> | |
5368 | |
5369 WARNING: The longer the tags file, the slower this will be, and the more | |
5370 memory Vim will consume. | |
5371 | |
5372 Only highlighting typedefs, unions and structs can be done too. For this you | |
5373 must use Exuberant ctags (found at http://ctags.sf.net). | |
5374 | |
5375 Put these lines in your Makefile: | |
5376 | |
5377 # Make a highlight file for types. Requires Exuberant ctags and awk | |
5378 types: types.vim | |
5379 types.vim: *.[ch] | |
1125 | 5380 ctags --c-kinds=gstu -o- *.[ch] |\ |
7 | 5381 awk 'BEGIN{printf("syntax keyword Type\t")}\ |
5382 {printf("%s ", $$1)}END{print ""}' > $@ | |
5383 | |
5384 And put these lines in your .vimrc: > | |
5385 | |
5386 " load the types.vim highlighting file, if it exists | |
5387 autocmd BufRead,BufNewFile *.[ch] let fname = expand('<afile>:p:h') . '/types.vim' | |
5388 autocmd BufRead,BufNewFile *.[ch] if filereadable(fname) | |
5389 autocmd BufRead,BufNewFile *.[ch] exe 'so ' . fname | |
5390 autocmd BufRead,BufNewFile *.[ch] endif | |

15194 | 5423 18. Color xterms *xterm-color* *color-xterm* |
7 | 5424 |
5425 Most color xterms have only eight colors. If you don't get colors with the | |
5426 default setup, it should work with these lines in your .vimrc: > | |
5427 :if &term =~ "xterm" | |
5428 : if has("terminfo") | |
5429 : set t_Co=8 | |
5430 : set t_Sf=<Esc>[3%p1%dm | |
5431 : set t_Sb=<Esc>[4%p1%dm | |
5432 : else | |
5433 : set t_Co=8 | |
5434 : set t_Sf=<Esc>[3%dm | |
5435 : set t_Sb=<Esc>[4%dm | |
5436 : endif | |
5437 :endif | |
5438 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
5439 | |
5440 You might want to change the first "if" to match the name of your terminal, | |
5441 e.g. "dtterm" instead of "xterm". | |
5442 | |
5443 Note: Do these settings BEFORE doing ":syntax on". Otherwise the colors may | |
5444 be wrong. | |
5445 *xiterm* *rxvt* | |
5446 The above settings have been mentioned to work for xiterm and rxvt too. | |
5447 But for using 16 colors in an rxvt these should work with terminfo: > | |
5448 :set t_AB=<Esc>[%?%p1%{8}%<%t25;%p1%{40}%+%e5;%p1%{32}%+%;%dm | |
5449 :set t_AF=<Esc>[%?%p1%{8}%<%t22;%p1%{30}%+%e1;%p1%{22}%+%;%dm | |
5450 < | |
5451 *colortest.vim* | |
5452 To test your color setup, a file has been included in the Vim distribution. | |
671 | 5453 To use it, execute this command: > |
5454 :runtime syntax/colortest.vim | |
7 | 5455 |
237 | 5456 Some versions of xterm (and other terminals, like the Linux console) can |
7 | 5457 output lighter foreground colors, even though the number of colors is defined |
5458 at 8. Therefore Vim sets the "cterm=bold" attribute for light foreground | |
5459 colors, when 't_Co' is 8. | |
5460 | |
5461 *xfree-xterm* | |
5462 To get 16 colors or more, get the newest xterm version (which should be | |
237 | 5463 included with XFree86 3.3 and later). You can also find the latest version |
7 | 5464 at: > |
5465 http://invisible-island.net/xterm/xterm.html | |
5466 Here is a good way to configure it. This uses 88 colors and enables the | |
5467 termcap-query feature, which allows Vim to ask the xterm how many colors it | |
5468 supports. > | |
5469 ./configure --disable-bold-color --enable-88-color --enable-tcap-query | |
5470 If you only get 8 colors, check the xterm compilation settings. | |
5471 (Also see |UTF8-xterm| for using this xterm with UTF-8 character encoding). | |
5472 | |
5473 This xterm should work with these lines in your .vimrc (for 16 colors): > | |
5474 :if has("terminfo") | |
5475 : set t_Co=16 | |
5476 : set t_AB=<Esc>[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{92}%+%;%dm | |
5477 : set t_AF=<Esc>[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{82}%+%;%dm | |
5478 :else | |
5479 : set t_Co=16 | |
5480 : set t_Sf=<Esc>[3%dm | |
5481 : set t_Sb=<Esc>[4%dm | |
5482 :endif | |
5483 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
5484 | |
5485 Without |+terminfo|, Vim will recognize these settings, and automatically | |
5486 translate cterm colors of 8 and above to "<Esc>[9%dm" and "<Esc>[10%dm". | |
5487 Colors above 16 are also translated automatically. | |
5488 | |
5489 For 256 colors this has been reported to work: > | |
5490 | |
5491 :set t_AB=<Esc>[48;5;%dm | |
5492 :set t_AF=<Esc>[38;5;%dm | |
5493 | |
5494 Or just set the TERM environment variable to "xterm-color" or "xterm-16color" | |
5495 and try if that works. | |
5496 | |
5497 You probably want to use these X resources (in your ~/.Xdefaults file): | |
5498 XTerm*color0: #000000 | |
5499 XTerm*color1: #c00000 | |
5500 XTerm*color2: #008000 | |
5501 XTerm*color3: #808000 | |
5502 XTerm*color4: #0000c0 | |
5503 XTerm*color5: #c000c0 | |
5504 XTerm*color6: #008080 | |
5505 XTerm*color7: #c0c0c0 | |
5506 XTerm*color8: #808080 | |
5507 XTerm*color9: #ff6060 | |
5508 XTerm*color10: #00ff00 | |
5509 XTerm*color11: #ffff00 | |
5510 XTerm*color12: #8080ff | |
5511 XTerm*color13: #ff40ff | |
5512 XTerm*color14: #00ffff | |
5513 XTerm*color15: #ffffff | |
5514 Xterm*cursorColor: Black | |
5515 | |
5516 [Note: The cursorColor is required to work around a bug, which changes the | |
5517 cursor color to the color of the last drawn text. This has been fixed by a | |
1125 | 5518 newer version of xterm, but not everybody is using it yet.] |
7 | 5519 |
5520 To get these right away, reload the .Xdefaults file to the X Option database | |
5521 Manager (you only need to do this when you just changed the .Xdefaults file): > | |
5522 xrdb -merge ~/.Xdefaults | |
5523 < | |
5524 *xterm-blink* *xterm-blinking-cursor* | |
5525 To make the cursor blink in an xterm, see tools/blink.c. Or use Thomas | |
5526 Dickey's xterm above patchlevel 107 (see above for where to get it), with | |
5527 these resources: | |
5528 XTerm*cursorBlink: on | |
5529 XTerm*cursorOnTime: 400 | |
5530 XTerm*cursorOffTime: 250 | |
5531 XTerm*cursorColor: White | |
5532 | |
5533 *hpterm-color* | |
1125 | 5534 These settings work (more or less) for an hpterm, which only supports 8 |
7 | 5535 foreground colors: > |
5536 :if has("terminfo") | |
5537 : set t_Co=8 | |
5538 : set t_Sf=<Esc>[&v%p1%dS | |
5539 : set t_Sb=<Esc>[&v7S | |
5540 :else | |
5541 : set t_Co=8 | |
5542 : set t_Sf=<Esc>[&v%dS | |
5543 : set t_Sb=<Esc>[&v7S | |
5544 :endif | |
5545 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
5546 | |
