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. | |

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

122 2. Syntax files *:syn-files* | |
123 | |
124 The syntax and highlighting commands for one language are normally stored in | |
125 a syntax file. The name convention is: "{name}.vim". Where {name} is the | |
126 name of the language, or an abbreviation (to fit the name in 8.3 characters, | |
127 a requirement in case the file is used on a DOS filesystem). | |
128 Examples: | |
129 c.vim perl.vim java.vim html.vim | |
130 cpp.vim sh.vim csh.vim | |
131 | |
132 The syntax file can contain any Ex commands, just like a vimrc file. But | |
133 the idea is that only commands for a specific language are included. When a | |
134 language is a superset of another language, it may include the other one, | |
135 for example, the cpp.vim file could include the c.vim file: > | |
136 :so $VIMRUNTIME/syntax/c.vim | |
137 | |
138 The .vim files are normally loaded with an autocommand. For example: > | |
139 :au Syntax c runtime! syntax/c.vim | |
140 :au Syntax cpp runtime! syntax/cpp.vim | |
141 These commands are normally in the file $VIMRUNTIME/syntax/synload.vim. | |
142 | |
143 | |
144 MAKING YOUR OWN SYNTAX FILES *mysyntaxfile* | |
145 | |
146 When you create your own syntax files, and you want to have Vim use these | |
147 automatically with ":syntax enable", do this: | |
148 | |
149 1. Create your user runtime directory. You would normally use the first item | |
150 of the 'runtimepath' option. Example for Unix: > | |
151 mkdir ~/.vim | |
152 | |
153 2. Create a directory in there called "syntax". For Unix: > | |
154 mkdir ~/.vim/syntax | |
155 | |
156 3. Write the Vim syntax file. Or download one from the internet. Then write | |
157 it in your syntax directory. For example, for the "mine" syntax: > | |
158 :w ~/.vim/syntax/mine.vim | |
159 | |
160 Now you can start using your syntax file manually: > | |
161 :set syntax=mine | |
162 You don't have to exit Vim to use this. | |
163 | |
164 If you also want Vim to detect the type of file, see |new-filetype|. | |
165 | |
166 If you are setting up a system with many users and you don't want each user | |
167 to add the same syntax file, you can use another directory from 'runtimepath'. | |
168 | |
169 | |
170 ADDING TO AN EXISTING SYNTAX FILE *mysyntaxfile-add* | |
171 | |
172 If you are mostly satisfied with an existing syntax file, but would like to | |
173 add a few items or change the highlighting, follow these steps: | |
174 | |
175 1. Create your user directory from 'runtimepath', see above. | |
176 | |
177 2. Create a directory in there called "after/syntax". For Unix: > | |
178 mkdir ~/.vim/after | |
179 mkdir ~/.vim/after/syntax | |
180 | |
181 3. Write a Vim script that contains the commands you want to use. For | |
182 example, to change the colors for the C syntax: > | |
183 highlight cComment ctermfg=Green guifg=Green | |
184 | |
185 4. Write that file in the "after/syntax" directory. Use the name of the | |
186 syntax, with ".vim" added. For our C syntax: > | |
187 :w ~/.vim/after/syntax/c.vim | |
188 | |
189 That's it. The next time you edit a C file the Comment color will be | |
190 different. You don't even have to restart Vim. | |
191 | |
169 | 192 If you have multiple files, you can use the filetype as the directory name. |
193 All the "*.vim" files in this directory will be used, for example: | |
194 ~/.vim/after/syntax/c/one.vim | |
195 ~/.vim/after/syntax/c/two.vim | |
196 | |
7 | 197 |
198 REPLACING AN EXISTING SYNTAX FILE *mysyntaxfile-replace* | |
199 | |
200 If you don't like a distributed syntax file, or you have downloaded a new | |
201 version, follow the same steps as for |mysyntaxfile| above. Just make sure | |
202 that you write the syntax file in a directory that is early in 'runtimepath'. | |
3445 | 203 Vim will only load the first syntax file found, assuming that it sets |
204 b:current_syntax. | |

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

261 *Ignore left blank, hidden |hl-Ignore| |
7 | 262 |
263 *Error any erroneous construct | |
264 | |
265 *Todo anything that needs extra attention; mostly the | |
266 keywords TODO FIXME and XXX | |
267 | |
268 The names marked with * are the preferred groups; the others are minor groups. | |
269 For the preferred groups, the "syntax.vim" file contains default highlighting. | |
270 The minor groups are linked to the preferred groups, so they get the same | |
271 highlighting. You can override these defaults by using ":highlight" commands | |
272 after sourcing the "syntax.vim" file. | |
273 | |
274 Note that highlight group names are not case sensitive. "String" and "string" | |
275 can be used for the same group. | |
276 | |
277 The following names are reserved and cannot be used as a group name: | |

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

402 - Some truly ancient browsers may not show the background colors. |
7 | 403 - From most browsers you can also print the file (in color)! |
3713 | 404 - The latest TOhtml may actually work with older versions of Vim, but some |
2642 | 405 features such as conceal support will not function, and the colors may be |
406 incorrect for an old Vim without GUI support compiled in. | |

408 Here is an example how to run the script over all .c and .h files from a | |

411 < | |
3713 | 412 *g:html_start_line* *g:html_end_line* |
413 To restrict the conversion to a range of lines, use a range with the |:TOhtml| | |
414 command below, or set "g:html_start_line" and "g:html_end_line" to the first | |
415 and last line to be converted. Example, using the last set Visual area: > | |
416 | |
417 :let g:html_start_line = line("'<") | |
418 :let g:html_end_line = line("'>") | |
419 :runtime! syntax/2html.vim | |
420 < | |
421 *:TOhtml* | |
422 :[range]TOhtml The ":TOhtml" command is defined in a standard plugin. | |
423 This command will source |2html.vim| for you. When a | |
424 range is given, set |g:html_start_line| and | |
425 |g:html_end_line| to the start and end of the range, | |
426 respectively. Default range is the entire buffer. | |

452 *g:html_whole_filler* | |
453 Default: 0. | |
454 When 0, if |g:html_diff_one_file| is 1, a sequence of more than 3 filler lines | |
455 is displayed as three lines with the middle line mentioning the total number | |
456 of inserted lines. | |
457 When 1, always display all inserted lines as if |g:html_diff_one_file| were | |
458 not set. | |
459 > | |
460 :let g:html_whole_filler = 1 | |
461 < | |
462 *TOhtml-performance* *g:html_no_progress* | |
463 Default: 0. | |
464 When 0, display a progress bar in the statusline for each major step in the | |
465 2html.vim conversion process. | |
466 When 1, do not display the progress bar. This offers a minor speed improvement | |
467 but you won't have any idea how much longer the conversion might take; for big | |
468 files it can take a long time! | |
469 Example: > | |
470 | |
471 let g:html_no_progress = 1 | |
472 < | |
473 You can obtain better performance improvements by also instructing Vim to not | |
474 run interactively, so that too much time is not taken to redraw as the script | |
475 moves through the buffer, switches windows, and the like: > | |
476 | |
477 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 | |
478 < | |
479 Note that the -s flag prevents loading your .vimrc and any plugins, so you | |
480 need to explicitly source/enable anything that will affect the HTML | |
481 conversion. See |-E| and |-s-ex| for details. It is probably best to create a | |
482 script to replace all the -c commands and use it with the -u flag instead of | |
483 specifying each command separately. | |
484 | |
485 *g:html_number_lines* | |
486 Default: current 'number' setting. | |
487 When 0, buffer text is displayed in the generated HTML without line numbering. | |
488 When 1, a column of line numbers is added to the generated HTML with the same | |
489 highlighting as the line number column in Vim (|hl-LineNr|). | |
490 Force line numbers even if 'number' is not set: > | |
491 :let g:html_number_lines = 1 | |
492 Force to omit the line numbers: > | |
493 :let g:html_number_lines = 0 | |
494 Go back to the default to use 'number' by deleting the variable: > | |
495 :unlet g:html_number_lines | |

3713 | 514 *g:html_use_css* |
515 Default: 1. | |
516 When 1, generate valid HTML 4.01 markup with CSS1 styling, supported in all | |
517 modern browsers and most old browsers. | |
518 When 0, generate <font> tags and similar outdated markup. This is not | |
519 recommended but it may work better in really old browsers, email clients, | |
520 forum posts, and similar situations where basic CSS support is unavailable. | |
521 Example: > | |
522 :let g:html_use_css = 0 | |
523 < | |
524 *g:html_ignore_conceal* | |
525 Default: 0. | |
526 When 0, concealed text is removed from the HTML and replaced with a character | |
527 from |:syn-cchar| or 'listchars' as appropriate, depending on the current | |
528 value of 'conceallevel'. | |
529 When 1, include all text from the buffer in the generated HTML, even if it is | |
530 |conceal|ed. | |
531 | |
532 Either of the following commands will ensure that all text in the buffer is | |
533 included in the generated HTML (unless it is folded): > | |
534 :let g:html_ignore_conceal = 1 | |
535 :setl conceallevel=0 | |
536 < | |
537 *g:html_ignore_folding* | |
538 Default: 0. | |
539 When 0, text in a closed fold is replaced by the text shown for the fold in | |
540 Vim (|fold-foldtext|). See |g:html_dynamic_folds| if you also want to allow | |
541 the user to expand the fold as in Vim to see the text inside. | |
542 When 1, include all text from the buffer in the generated HTML; whether the | |
543 text is in a fold has no impact at all. |g:html_dynamic_folds| has no effect. | |
544 | |
545 Either of these commands will ensure that all text in the buffer is included | |
546 in the generated HTML (unless it is concealed): > | |
547 zR | |
548 :let g:html_ignore_folding = 1 | |
549 < | |
550 *g:html_dynamic_folds* | |
551 Default: 0. | |
552 When 0, text in a closed fold is not included at all in the generated HTML. | |
553 When 1, generate javascript to open a fold and show the text within, just like | |
554 in Vim. | |
555 | |
556 Setting this variable to 1 causes 2html.vim to always use CSS for styling, | |
557 regardless of what |g:html_use_css| is set to. | |
558 | |
559 This variable is ignored when |g:html_ignore_folding| is set. | |
560 > | |
561 :let g:html_dynamic_folds = 1 | |
562 < | |
563 *g:html_no_foldcolumn* | |
564 Default: 0. | |
565 When 0, if |g:html_dynamic_folds| is 1, generate a column of text similar to | |
566 Vim's foldcolumn (|fold-foldcolumn|) the user can click on to toggle folds | |
567 open or closed. The minimum width of the generated text column is the current | |
568 'foldcolumn' setting. | |
569 When 1, do not generate this column; instead, hovering the mouse cursor over | |
570 folded text will open the fold as if |g:html_hover_unfold| were set. | |
571 > | |
572 :let g:html_no_foldcolumn = 1 | |
573 < | |
574 *TOhtml-uncopyable-text* *g:html_prevent_copy* | |
575 Default: empty string. | |
576 This option prevents certain regions of the generated HTML from being copied, | |
577 when you select all text in document rendered in a browser and copy it. Useful | |
578 for allowing users to copy-paste only the source text even if a fold column or | |
579 line numbers are shown in the generated content. Specify regions to be | |
580 affected in this way as follows: | |
581 f: fold column | |
582 n: line numbers (also within fold text) | |
583 t: fold text | |
584 d: diff filler | |
585 | |
586 Example, to make the fold column and line numbers uncopyable: > | |
587 :let g:html_prevent_copy = "fn" | |
588 < | |
589 This feature is currently implemented by inserting read-only <input> elements | |
590 into the markup to contain the uncopyable areas. This does not work well in | |
591 all cases. When pasting to some applications which understand HTML, the | |
592 <input> elements also get pasted. But plain-text paste destinations should | |
593 always work. | |
594 | |
595 *g:html_no_invalid* | |
596 Default: 0. | |
597 When 0, if |g:html_prevent_copy| is non-empty, an invalid attribute is | |
598 intentionally inserted into the <input> element for the uncopyable areas. This | |
599 increases the number of applications you can paste to without also pasting the | |
600 <input> elements. Specifically, Microsoft Word will not paste the <input> | |
601 elements if they contain this invalid attribute. | |
602 When 1, no invalid markup is ever intentionally inserted, and the generated | |
603 page should validate. However, be careful pasting into Microsoft Word when | |
604 |g:html_prevent_copy| is non-empty; it can be hard to get rid of the <input> | |
605 elements which get pasted. | |
606 | |
607 *g:html_hover_unfold* | |
608 Default: 0. | |
609 When 0, the only way to open a fold generated by 2html.vim with | |
610 |g:html_dynamic_folds| set, is to click on the generated fold column. | |
611 When 1, use CSS 2.0 to allow the user to open a fold by moving the mouse | |
612 cursor over the displayed fold text. This is useful to allow users with | |
613 disabled javascript to view the folded text. | |
614 | |
615 Note that old browsers (notably Internet Explorer 6) will not support this | |
616 feature. Browser-specific markup for IE6 is included to fall back to the | |
617 normal CSS1 styling so that the folds show up correctly for this browser, but | |
618 they will not be openable without a foldcolumn. | |

655 *g:html_no_pre* | |
656 Default: 0. | |
657 When 0, buffer text in the generated HTML is surrounded by <pre>...</pre> | |
658 tags. Series of whitespace is shown as in Vim without special markup, and tab | |
659 characters can be included literally (see |g:html_expand_tabs|). | |
660 When 1 (not recommended), the <pre> tags are omitted, and a plain <div> is | |
661 used instead. Whitespace is replaced by a series of character | |
662 references, and <br> is used to end each line. This is another way to allow | |
663 text in the generated HTML is wrap (see |g:html_pre_wrap|) which also works in | |
664 old browsers, but may cause noticeable differences between Vim's display and | |
665 the rendered page generated by 2html.vim. | |
666 > | |
667 :let g:html_no_pre = 1 | |
668 < | |
669 *g:html_expand_tabs* | |
670 Default: 1 if 'tabstop' is 8, 'expandtab' is 0, and no fold column or line | |
671 numbers occur in the generated HTML; | |
672 0 otherwise. | |
673 When 0, <Tab> characters in the buffer text are replaced with an appropriate | |
674 number of space characters, or references if |g:html_no_pre| is 1. | |
675 When 1, if |g:html_no_pre| is 0 or unset, <Tab> characters in the buffer text | |
676 are included as-is in the generated HTML. This is useful for when you want to | |
677 allow copy and paste from a browser without losing the actual whitespace in | |
678 the source document. Note that this can easily break text alignment and | |
679 indentation in the HTML, unless set by default. | |
680 | |
681 Force |2html.vim| to keep <Tab> characters: > | |
682 :let g:html_expand_tabs = 0 | |
683 < | |
684 Force tabs to be expanded: > | |
685 :let g:html_expand_tabs = 1 | |
686 < | |
687 *TOhtml-encoding-detect* *TOhtml-encoding* | |
688 It is highly recommended to set your desired encoding with | |
689 |g:html_use_encoding| for any content which will be placed on a web server. | |
690 | |
691 If you do not specify an encoding, |2html.vim| uses the preferred IANA name | |
692 for the current value of 'fileencoding' if set, or 'encoding' if not. | |
693 'encoding' is always used for certain 'buftype' values. 'fileencoding' will be | |
694 set to match the chosen document encoding. | |
695 | |
696 Automatic detection works for the encodings mentioned specifically by name in | |
697 |encoding-names|, but TOhtml will only automatically use those encodings with | |
698 wide browser support. However, you can override this to support specific | |
699 encodings that may not be automatically detected by default (see options | |
700 below). See http://www.iana.org/assignments/character-sets for the IANA names. | |
701 | |
702 Note, by default all Unicode encodings are converted to UTF-8 with no BOM in | |
703 the generated HTML, as recommended by W3C: | |
704 | |
705 http://www.w3.org/International/questions/qa-choosing-encodings | |
706 http://www.w3.org/International/questions/qa-byte-order-mark | |
707 | |
708 *g:html_use_encoding* | |
709 Default: none, uses IANA name for current 'fileencoding' as above. | |
710 To overrule all automatic charset detection, set g:html_use_encoding to the | |
711 name of the charset to be used. It is recommended to set this variable to | |
712 something widely supported, like UTF-8, for anything you will be hosting on a | |
713 webserver: > | |
714 :let g:html_use_encoding = "UTF-8" | |
715 You can also use this option to omit the line that specifies the charset | |
716 entirely, by setting g:html_use_encoding to an empty string (NOT recommended): > | |
717 :let g:html_use_encoding = "" | |
718 To go back to the automatic mechanism, delete the |g:html_use_encoding| | |
719 variable: > | |
720 :unlet g:html_use_encoding | |
721 < | |
722 *g:html_encoding_override* | |
723 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
724 mentioned by name at |encoding-names|. | |
725 This option allows |2html.vim| to detect the correct 'fileencoding' when you | |
726 specify an encoding with |g:html_use_encoding| which is not in the default | |
727 list of conversions. | |
728 | |
729 This is a dictionary of charset-encoding pairs that will replace existing | |
730 pairs automatically detected by TOhtml, or supplement with new pairs. | |
731 | |
732 Detect the HTML charset "windows-1252" as the encoding "8bit-cp1252": > | |
733 :let g:html_encoding_override = {'windows-1252': '8bit-cp1252'} | |
734 < | |
735 *g:html_charset_override* | |
736 Default: none, autoload/tohtml.vim contains default conversions for encodings | |
737 mentioned by name at |encoding-names| and which have wide | |
738 browser support. | |
739 This option allows |2html.vim| to detect the HTML charset for any | |
740 'fileencoding' or 'encoding' which is not detected automatically. You can also | |
741 use it to override specific existing encoding-charset pairs. For example, | |
742 TOhtml will by default use UTF-8 for all Unicode/UCS encodings. To use UTF-16 | |
743 and UTF-32 instead, use: > | |
744 :let g:html_charset_override = {'ucs-4': 'UTF-32', 'utf-16': 'UTF-16'} | |
745 | |
746 Note that documents encoded in either UTF-32 or UTF-16 have known | |
747 compatibility problems with some major browsers. | |
748 | |
749 *convert-to-XML* *convert-to-XHTML* *g:html_use_xhtml* | |
750 Default: 0. | |
751 When 0, generate standard HTML 4.01 (strict when possible). | |
752 When 1, generate XHTML 1.0 instead (XML compliant HTML). | |
753 > | |
754 :let g:html_use_xhtml = 1 | |

501 | 757 ABEL *abel.vim* *ft-abel-syntax* |
7 | 758 |
759 ABEL highlighting provides some user-defined options. To enable them, assign | |
760 any value to the respective variable. Example: > | |
761 :let abel_obsolete_ok=1 | |
762 To disable them use ":unlet". Example: > | |
763 :unlet abel_obsolete_ok | |
764 | |
765 Variable Highlight ~ | |
766 abel_obsolete_ok obsolete keywords are statements, not errors | |

501 | 775 ANT *ant.vim* *ft-ant-syntax* |
7 | 776 |
777 The ant syntax file provides syntax highlighting for javascript and python | |
237 | 778 by default. Syntax highlighting for other script languages can be installed |
7 | 779 by the function AntSyntaxScript(), which takes the tag name as first argument |
237 | 780 and the script syntax file name as second argument. Example: > |
7 | 781 |
782 :call AntSyntaxScript('perl', 'perl.vim') | |
783 | |
784 will install syntax perl highlighting for the following ant code > | |
785 | |
786 <script language = 'perl'><![CDATA[ | |
787 # everything inside is highlighted as perl | |

501 | 793 APACHE *apache.vim* *ft-apache-syntax* |
7 | 794 |
795 The apache syntax file provides syntax highlighting depending on Apache HTTP | |
796 server version, by default for 1.3.x. Set "apache_version" to Apache version | |
797 (as a string) to get highlighting for another version. Example: > | |
798 | |
799 :let apache_version = "2.0" | |
800 < | |
801 | |
802 *asm.vim* *asmh8300.vim* *nasm.vim* *masm.vim* *asm68k* | |

804 *ft-masm-syntax* *ft-asm68k-syntax* *fasm.vim* | |
7 | 805 |
806 Files matching "*.i" could be Progress or Assembly. If the automatic detection | |
807 doesn't work for you, or you don't edit Progress at all, use this in your | |
808 startup vimrc: > | |
809 :let filetype_i = "asm" | |
810 Replace "asm" with the type of assembly you use. | |
811 | |
812 There are many types of assembly languages that all use the same file name | |
813 extensions. Therefore you will have to select the type yourself, or add a | |
814 line in the assembly file that Vim will recognize. Currently these syntax | |
815 files are included: | |
816 asm GNU assembly (the default) | |
817 asm68k Motorola 680x0 assembly | |
818 asmh8300 Hitachi H-8300 version of GNU assembly | |
819 ia64 Intel Itanium 64 | |
820 fasm Flat assembly (http://flatassembler.net) | |
821 masm Microsoft assembly (probably works for any 80x86) | |
822 nasm Netwide assembly | |
823 tasm Turbo Assembly (with opcodes 80x86 up to Pentium, and | |
824 MMX) | |
825 pic PIC assembly (currently for PIC16F84) | |
826 | |
827 The most flexible is to add a line in your assembly file containing: > | |
2033

|
830 one of the first five lines in the file. No non-white text must be |
3682 | 831 immediately before or after this text. Note that specifying asmsyntax=foo is |
832 equivalent to setting ft=foo in a |modeline|, and that in case of a conflict | |
833 between the two settings the one from the modeline will take precedence (in | |
834 particular, if you have ft=asm in the modeline, you will get the GNU syntax | |
835 highlighting regardless of what is specified as asmsyntax). | |
7 | 836 |
837 The syntax type can always be overruled for a specific buffer by setting the | |
838 b:asmsyntax variable: > | |
1624 | 839 :let b:asmsyntax = "nasm" |
7 | 840 |
841 If b:asmsyntax is not set, either automatically or by hand, then the value of | |
842 the global variable asmsyntax is used. This can be seen as a default assembly | |
843 language: > | |
1624 | 844 :let asmsyntax = "nasm" |
7 | 845 |
846 As a last resort, if nothing is defined, the "asm" syntax is used. | |

501 | 863 ASPPERL and ASPVBS *ft-aspperl-syntax* *ft-aspvbs-syntax* |
7 | 864 |
865 *.asp and *.asa files could be either Perl or Visual Basic script. Since it's | |
866 hard to detect this you can set two global variables to tell Vim what you are | |
867 using. For Perl script use: > | |
868 :let g:filetype_asa = "aspperl" | |
869 :let g:filetype_asp = "aspperl" | |
870 For Visual Basic use: > | |
871 :let g:filetype_asa = "aspvbs" | |
872 :let g:filetype_asp = "aspvbs" | |
873 | |
874 | |
856 | 875 BAAN *baan.vim* *baan-syntax* |
844 | 876 |
877 The baan.vim gives syntax support for BaanC of release BaanIV upto SSA ERP LN | |
878 for both 3 GL and 4 GL programming. Large number of standard defines/constants | |
879 are supported. | |
880 | |
881 Some special violation of coding standards will be signalled when one specify | |
882 in ones |.vimrc|: > | |
883 let baan_code_stds=1 | |
884 | |
885 *baan-folding* | |
886 | |
887 Syntax folding can be enabled at various levels through the variables | |
888 mentioned below (Set those in your |.vimrc|). The more complex folding on | |
889 source blocks and SQL can be CPU intensive. | |
890 | |
891 To allow any folding and enable folding at function level use: > | |
892 let baan_fold=1 | |
893 Folding can be enabled at source block level as if, while, for ,... The | |
894 indentation preceding the begin/end keywords has to match (spaces are not | |
895 considered equal to a tab). > | |
896 let baan_fold_block=1 | |
897 Folding can be enabled for embedded SQL blocks as SELECT, SELECTDO, | |
856 | 898 SELECTEMPTY, ... The indentation preceding the begin/end keywords has to |
844 | 899 match (spaces are not considered equal to a tab). > |
900 let baan_fold_sql=1 | |
856 | 901 Note: Block folding can result in many small folds. It is suggested to |:set| |
844 | 902 the options 'foldminlines' and 'foldnestmax' in |.vimrc| or use |:setlocal| in |
903 .../after/syntax/baan.vim (see |after-directory|). Eg: > | |
904 set foldminlines=5 | |
905 set foldnestmax=6 | |
906 | |
907 | |
501 | 908 BASIC *basic.vim* *vb.vim* *ft-basic-syntax* *ft-vb-syntax* |
7 | 909 |
910 Both Visual Basic and "normal" basic use the extension ".bas". To detect | |
911 which one should be used, Vim checks for the string "VB_Name" in the first | |
912 five lines of the file. If it is not found, filetype will be "basic", | |
913 otherwise "vb". Files with the ".frm" extension will always be seen as Visual | |
914 Basic. | |
915 | |
916 | |
501 | 917 C *c.vim* *ft-c-syntax* |
7 | 918 |
919 A few things in C highlighting are optional. To enable them assign any value | |
920 to the respective variable. Example: > | |
1624 | 921 :let c_comment_strings = 1 |
7 | 922 To disable them use ":unlet". Example: > |
923 :unlet c_comment_strings | |
924 | |
925 Variable Highlight ~ | |
926 c_gnu GNU gcc specific items | |
927 c_comment_strings strings and numbers inside a comment | |
928 c_space_errors trailing white space and spaces before a <Tab> | |
929 c_no_trail_space_error ... but no trailing spaces | |
930 c_no_tab_space_error ... but no spaces before a <Tab> | |
931 c_no_bracket_error don't highlight {}; inside [] as errors | |
140 | 932 c_no_curly_error don't highlight {}; inside [] and () as errors; |
933 except { and } in first column | |
1624 | 934 c_curly_error highlight a missing }; this forces syncing from the |
935 start of the file, can be slow | |
7 | 936 c_no_ansi don't do standard ANSI types and constants |
937 c_ansi_typedefs ... but do standard ANSI types | |
938 c_ansi_constants ... but do standard ANSI constants | |
939 c_no_utf don't highlight \u and \U in strings | |
3445 | 940 c_syntax_for_h for *.h files use C syntax instead of C++ and use objc |
941 syntax instead of objcpp | |
7 | 942 c_no_if0 don't highlight "#if 0" blocks as comments |
943 c_no_cformat don't highlight %-formats in strings | |
944 c_no_c99 don't highlight C99 standard items | |
3256 | 945 c_no_c11 don't highlight C11 standard items |
7 | 946 |
36 | 947 When 'foldmethod' is set to "syntax" then /* */ comments and { } blocks will |
948 become a fold. If you don't want comments to become a fold use: > | |
949 :let c_no_comment_fold = 1 | |
842 | 950 "#if 0" blocks are also folded, unless: > |
951 :let c_no_if0_fold = 1 | |
36 | 952 |
7 | 953 If you notice highlighting errors while scrolling backwards, which are fixed |
954 when redrawing with CTRL-L, try setting the "c_minlines" internal variable | |
955 to a larger number: > | |
956 :let c_minlines = 100 | |
957 This will make the syntax synchronization start 100 lines before the first | |
958 displayed line. The default value is 50 (15 when c_no_if0 is set). The | |
959 disadvantage of using a larger number is that redrawing can become slow. | |
960 | |
961 When using the "#if 0" / "#endif" comment highlighting, notice that this only | |
962 works when the "#if 0" is within "c_minlines" from the top of the window. If | |
963 you have a long "#if 0" construct it will not be highlighted correctly. | |
964 | |
965 To match extra items in comments, use the cCommentGroup cluster. | |
966 Example: > | |
967 :au Syntax c call MyCadd() | |
968 :function MyCadd() | |
969 : syn keyword cMyItem contained Ni | |
970 : syn cluster cCommentGroup add=cMyItem | |
971 : hi link cMyItem Title | |
972 :endfun | |
973 | |
974 ANSI constants will be highlighted with the "cConstant" group. This includes | |
975 "NULL", "SIG_IGN" and others. But not "TRUE", for example, because this is | |
976 not in the ANSI standard. If you find this confusing, remove the cConstant | |
977 highlighting: > | |
978 :hi link cConstant NONE | |
979 | |
980 If you see '{' and '}' highlighted as an error where they are OK, reset the | |
981 highlighting for cErrInParen and cErrInBracket. | |
982 | |
983 If you want to use folding in your C files, you can add these lines in a file | |

7 | 1000 |
1001 Chill syntax highlighting is similar to C. See |c.vim| for all the settings | |
1002 that are available. Additionally there is: | |
1003 | |
1004 chill_space_errors like c_space_errors | |
1005 chill_comment_string like c_comment_strings | |
1006 chill_minlines like c_minlines | |

501 | 1009 CHANGELOG *changelog.vim* *ft-changelog-syntax* |
7 | 1010 |
1011 ChangeLog supports highlighting spaces at the start of a line. | |
1012 If you do not like this, add following line to your .vimrc: > | |
1013 let g:changelog_spacing_errors = 0 | |
1014 This works the next time you edit a changelog file. You can also use | |
1015 "b:changelog_spacing_errors" to set this per buffer (before loading the syntax | |
1016 file). | |
1017 | |
1018 You can change the highlighting used, e.g., to flag the spaces as an error: > | |
1019 :hi link ChangelogError Error | |
1020 Or to avoid the highlighting: > | |
1021 :hi link ChangelogError NONE | |

1027 COBOL highlighting has different needs for legacy code than it does for fresh | |
1028 development. This is due to differences in what is being done (maintenance | |
1029 versus development) and other factors. To enable legacy code highlighting, | |
1030 add this line to your .vimrc: > | |
1031 :let cobol_legacy_code = 1 | |
1032 To disable it again, use this: > | |

1056 This covers the shell named "csh". Note that on some systems tcsh is actually | |
1057 used. | |
1058 | |
1059 Detecting whether a file is csh or tcsh is notoriously hard. Some systems | |
1060 symlink /bin/csh to /bin/tcsh, making it almost impossible to distinguish | |
1061 between csh and tcsh. In case VIM guesses wrong you can set the | |
2965 | 1062 "filetype_csh" variable. For using csh: *g:filetype_csh* |
1063 > | |
1064 :let g:filetype_csh = "csh" | |

1066 For using tcsh: > | |
1067 | |
2965 | 1068 :let g:filetype_csh = "tcsh" |
7 | 1069 |
1070 Any script with a tcsh extension or a standard tcsh filename (.tcshrc, | |
1071 tcsh.tcshrc, tcsh.login) will have filetype tcsh. All other tcsh/csh scripts | |
237 | 1072 will be classified as tcsh, UNLESS the "filetype_csh" variable exists. If the |
7 | 1073 "filetype_csh" variable exists, the filetype will be set to the value of the |
1074 variable. | |

1079 Cynlib files are C++ files that use the Cynlib class library to enable | |
237 | 1080 hardware modelling and simulation using C++. Typically Cynlib files have a .cc |
7 | 1081 or a .cpp extension, which makes it very difficult to distinguish them from a |
237 | 1082 normal C++ file. Thus, to enable Cynlib highlighting for .cc files, add this |
7 | 1083 line to your .vimrc file: > |
1084 | |
1085 :let cynlib_cyntax_for_cc=1 | |
1086 | |
1087 Similarly for cpp files (this extension is only usually used in Windows) > | |
1088 | |
1089 :let cynlib_cyntax_for_cpp=1 | |
1090 | |
1091 To disable these again, use this: > | |
1092 | |
1093 :unlet cynlib_cyntax_for_cc | |
1094 :unlet cynlib_cyntax_for_cpp | |
1095 < | |
1096 | |
501 | 1097 CWEB *cweb.vim* *ft-cweb-syntax* |
7 | 1098 |
1099 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
1100 doesn't work for you, or you don't edit Progress at all, use this in your | |
1101 startup vimrc: > | |
1102 :let filetype_w = "cweb" | |
1103 | |
1104 | |
501 | 1105 DESKTOP *desktop.vim* *ft-desktop-syntax* |
7 | 1106 |
1107 Primary goal of this syntax file is to highlight .desktop and .directory files | |

7 | 1110 But actually almost none implements this standard fully. Thus it will |
237 | 1111 highlight all Unix ini files. But you can force strict highlighting according |
7 | 1112 to standard by placing this in your vimrc file: > |

1114 | |
1115 | |
501 | 1116 DIRCOLORS *dircolors.vim* *ft-dircolors-syntax* |
7 | 1117 |
1118 The dircolors utility highlighting definition has one option. It exists to | |
1119 provide compatibility with the Slackware GNU/Linux distributions version of | |
1120 the command. It adds a few keywords that are generally ignored by most | |
1121 versions. On Slackware systems, however, the utility accepts the keywords and | |
1122 uses them for processing. To enable the Slackware keywords add the following | |
1123 line to your startup file: > | |
1124 let dircolors_is_slackware = 1 | |
1125 | |
1126 | |
501 | 1127 DOCBOOK *docbk.vim* *ft-docbk-syntax* *docbook* |
2662 | 1128 DOCBOOK XML *docbkxml.vim* *ft-docbkxml-syntax* |
1129 DOCBOOK SGML *docbksgml.vim* *ft-docbksgml-syntax* | |
7 | 1130 |
1131 There are two types of DocBook files: SGML and XML. To specify what type you | |
1132 are using the "b:docbk_type" variable should be set. Vim does this for you | |
1133 automatically if it can recognize the type. When Vim can't guess it the type | |
1134 defaults to XML. | |
1135 You can set the type manually: > | |
1136 :let docbk_type = "sgml" | |
1137 or: > | |
1138 :let docbk_type = "xml" | |
1139 You need to do this before loading the syntax file, which is complicated. | |
1140 Simpler is setting the filetype to "docbkxml" or "docbksgml": > | |
1141 :set filetype=docbksgml | |
1142 or: > | |
1143 :set filetype=docbkxml | |
1144 | |
3967 | 1145 You can specify the DocBook version: > |
1146 :let docbk_ver = 3 | |
1147 When not set 4 is used. | |
1148 | |
7 | 1149 |
501 | 1150 DOSBATCH *dosbatch.vim* *ft-dosbatch-syntax* |
7 | 1151 |
1152 There is one option with highlighting DOS batch files. This covers new | |
1153 extensions to the Command Interpreter introduced with Windows 2000 and | |
1154 is controlled by the variable dosbatch_cmdextversion. For Windows NT | |
1155 this should have the value 1, and for Windows 2000 it should be 2. | |
1156 Select the version you want with the following line: > | |
1157 | |
15 | 1158 :let dosbatch_cmdextversion = 1 |
7 | 1159 |
1160 If this variable is not defined it defaults to a value of 2 to support | |
1161 Windows 2000. | |
1162 | |
15 | 1163 A second option covers whether *.btm files should be detected as type |
237 | 1164 "dosbatch" (MS-DOS batch files) or type "btm" (4DOS batch files). The latter |
1165 is used by default. You may select the former with the following line: > | |
15 | 1166 |
1167 :let g:dosbatch_syntax_for_btm = 1 | |
1168 | |
1169 If this variable is undefined or zero, btm syntax is selected. | |
1170 | |
1171 | |
832 | 1172 DOXYGEN *doxygen.vim* *doxygen-syntax* |
1173 | |
1174 Doxygen generates code documentation using a special documentation format | |
1698 | 1175 (similar to Javadoc). This syntax script adds doxygen highlighting to c, cpp, |
1176 idl and php files, and should also work with java. | |
832 | 1177 |
1224 | 1178 There are a few of ways to turn on doxygen formatting. It can be done |
1179 explicitly or in a modeline by appending '.doxygen' to the syntax of the file. | |
1180 Example: > | |
832 | 1181 :set syntax=c.doxygen |
1182 or > | |
1183 // vim:syntax=c.doxygen | |
1184 | |
3356 | 1185 It can also be done automatically for C, C++, C#, IDL and PHP files by setting |
1186 the global or buffer-local variable load_doxygen_syntax. This is done by | |
1187 adding the following to your .vimrc. > | |
832 | 1188 :let g:load_doxygen_syntax=1 |

1190 There are a couple of variables that have an effect on syntax highlighting, and |
832 | 1191 are to do with non-standard highlighting options. |
1192 | |
1193 Variable Default Effect ~ | |
1194 g:doxygen_enhanced_color | |
1195 g:doxygen_enhanced_colour 0 Use non-standard highlighting for | |
1196 doxygen comments. | |
1197 | |

1199 and html_my_rendering underline. | |
1200 | |
1201 doxygen_javadoc_autobrief 1 Set to 0 to disable javadoc autobrief | |
1202 colour highlighting. | |
1203 | |
1204 doxygen_end_punctuation '[.]' Set to regexp match for the ending | |
856 | 1205 punctuation of brief |
832 | 1206 |
1207 There are also some hilight groups worth mentioning as they can be useful in | |
1208 configuration. | |
1209 | |
1210 Highlight Effect ~ | |
1211 doxygenErrorComment The colour of an end-comment when missing | |
1212 punctuation in a code, verbatim or dot section | |
1213 doxygenLinkError The colour of an end-comment when missing the | |
1214 \endlink from a \link section. | |
1215 | |
7 | 1216 |
501 | 1217 DTD *dtd.vim* *ft-dtd-syntax* |
7 | 1218 |
237 | 1219 The DTD syntax highlighting is case sensitive by default. To disable |
7 | 1220 case-sensitive highlighting, add the following line to your startup file: > |
1221 | |
1222 :let dtd_ignore_case=1 | |
1223 | |
237 | 1224 The DTD syntax file will highlight unknown tags as errors. If |
7 | 1225 this is annoying, it can be turned off by setting: > |
1226 | |
1227 :let dtd_no_tag_errors=1 | |
1228 | |
1229 before sourcing the dtd.vim syntax file. | |
1230 Parameter entity names are highlighted in the definition using the | |
1231 'Type' highlighting group and 'Comment' for punctuation and '%'. | |
1232 Parameter entity instances are highlighted using the 'Constant' | |
1233 highlighting group and the 'Type' highlighting group for the | |
237 | 1234 delimiters % and ;. This can be turned off by setting: > |
7 | 1235 |
1236 :let dtd_no_param_entities=1 | |
1237 | |
1238 The DTD syntax file is also included by xml.vim to highlight included dtd's. | |
1239 | |
1240 | |
501 | 1241 EIFFEL *eiffel.vim* *ft-eiffel-syntax* |
7 | 1242 |
1243 While Eiffel is not case-sensitive, its style guidelines are, and the | |
237 | 1244 syntax highlighting file encourages their use. This also allows to |
1245 highlight class names differently. If you want to disable case-sensitive | |
7 | 1246 highlighting, add the following line to your startup file: > |
1247 | |
1248 :let eiffel_ignore_case=1 | |
1249 | |
1250 Case still matters for class names and TODO marks in comments. | |
1251 | |
1252 Conversely, for even stricter checks, add one of the following lines: > | |
1253 | |
1254 :let eiffel_strict=1 | |
1255 :let eiffel_pedantic=1 | |
1256 | |
1257 Setting eiffel_strict will only catch improper capitalization for the | |
1258 five predefined words "Current", "Void", "Result", "Precursor", and | |
1259 "NONE", to warn against their accidental use as feature or class names. | |
1260 | |
1261 Setting eiffel_pedantic will enforce adherence to the Eiffel style | |
1262 guidelines fairly rigorously (like arbitrary mixes of upper- and | |
1263 lowercase letters as well as outdated ways to capitalize keywords). | |
1264 | |
1265 If you want to use the lower-case version of "Current", "Void", | |
1266 "Result", and "Precursor", you can use > | |
1267 | |
1268 :let eiffel_lower_case_predef=1 | |
1269 | |
1270 instead of completely turning case-sensitive highlighting off. | |
1271 | |
1272 Support for ISE's proposed new creation syntax that is already | |
1273 experimentally handled by some compilers can be enabled by: > | |
1274 | |
1275 :let eiffel_ise=1 | |
1276 | |
237 | 1277 Finally, some vendors support hexadecimal constants. To handle them, add > |
7 | 1278 |
1279 :let eiffel_hex_constants=1 | |
1280 | |
1281 to your startup file. | |

857 | 1299 FLEXWIKI *flexwiki.vim* *ft-flexwiki-syntax* |
1300 | |
1301 FlexWiki is an ASP.NET-based wiki package available at http://www.flexwiki.com | |
2826 | 1302 NOTE: this site currently doesn't work, on Wikipedia is mentioned that |
1303 development stopped in 2009. | |
857 | 1304 |
1305 Syntax highlighting is available for the most common elements of FlexWiki | |
1306 syntax. The associated ftplugin script sets some buffer-local options to make | |
1307 editing FlexWiki pages more convenient. FlexWiki considers a newline as the | |
1308 start of a new paragraph, so the ftplugin sets 'tw'=0 (unlimited line length), | |
1309 'wrap' (wrap long lines instead of using horizontal scrolling), 'linebreak' | |
1310 (to wrap at a character in 'breakat' instead of at the last char on screen), | |
1311 and so on. It also includes some keymaps that are disabled by default. | |
1312 | |
1313 If you want to enable the keymaps that make "j" and "k" and the cursor keys | |
1314 move up and down by display lines, add this to your .vimrc: > | |
1315 :let flexwiki_maps = 1 | |
1316 | |
1317 | |
501 | 1318 FORM *form.vim* *ft-form-syntax* |
7 | 1319 |
1320 The coloring scheme for syntax elements in the FORM file uses the default | |
1321 modes Conditional, Number, Statement, Comment, PreProc, Type, and String, | |
1275 | 1322 following the language specifications in 'Symbolic Manipulation with FORM' by |
7 | 1323 J.A.M. Vermaseren, CAN, Netherlands, 1991. |
1324 | |
1325 If you want include your own changes to the default colors, you have to | |
1326 redefine the following syntax groups: | |
1327 | |
1328 - formConditional | |
1329 - formNumber | |
1330 - formStatement | |
1331 - formHeaderStatement | |
1332 - formComment | |
1333 - formPreProc | |
1334 - formDirective | |
1335 - formType | |
1336 - formString | |
1337 | |
1338 Note that the form.vim syntax file implements FORM preprocessor commands and | |
1339 directives per default in the same syntax group. | |
1340 | |
1341 A predefined enhanced color mode for FORM is available to distinguish between | |
237 | 1342 header statements and statements in the body of a FORM program. To activate |
7 | 1343 this mode define the following variable in your vimrc file > |
1344 | |
1345 :let form_enhanced_color=1 | |
1346 | |
1347 The enhanced mode also takes advantage of additional color features for a dark | |
237 | 1348 gvim display. Here, statements are colored LightYellow instead of Yellow, and |
7 | 1349 conditionals are LightBlue for better distinction. |
1350 | |
1351 | |
501 | 1352 FORTRAN *fortran.vim* *ft-fortran-syntax* |
7 | 1353 |
1354 Default highlighting and dialect ~ | |
3256 | 1355 Highlighting appropriate for Fortran 2008 is used by default. This choice |
4992 | 1356 should be appropriate for most users most of the time because Fortran 2008 is |
1357 almost a superset of previous versions (Fortran 2003, 95, 90, and 77). | |
7 | 1358 |
1359 Fortran source code form ~ | |
3281 | 1360 Fortran code can be in either fixed or free source form. Note that the |
7 | 1361 syntax highlighting will not be correct if the form is incorrectly set. |
1362 | |
1363 When you create a new fortran file, the syntax script assumes fixed source | |
237 | 1364 form. If you always use free source form, then > |
7 | 1365 :let fortran_free_source=1 |
237 | 1366 in your .vimrc prior to the :syntax on command. If you always use fixed source |
7 | 1367 form, then > |
1368 :let fortran_fixed_source=1 | |
1369 in your .vimrc prior to the :syntax on command. | |
1370 | |
1371 If the form of the source code depends upon the file extension, then it is | |
237 | 1372 most convenient to set fortran_free_source in a ftplugin file. For more |
1373 information on ftplugin files, see |ftplugin|. For example, if all your | |
7 | 1374 fortran files with an .f90 extension are written in free source form and the |
1375 rest in fixed source form, add the following code to your ftplugin file > | |
1376 let s:extfname = expand("%:e") | |
1377 if s:extfname ==? "f90" | |
1378 let fortran_free_source=1 | |
1379 unlet! fortran_fixed_source | |
1380 else | |
1381 let fortran_fixed_source=1 | |
1382 unlet! fortran_free_source | |
1383 endif | |
1384 Note that this will work only if the "filetype plugin indent on" command | |
1385 precedes the "syntax on" command in your .vimrc file. | |
1386 | |
1387 When you edit an existing fortran file, the syntax script will assume free | |
1388 source form if the fortran_free_source variable has been set, and assumes | |
237 | 1389 fixed source form if the fortran_fixed_source variable has been set. If |
7 | 1390 neither of these variables have been set, the syntax script attempts to |
1391 determine which source form has been used by examining the first five columns | |
819 | 1392 of the first 250 lines of your file. If no signs of free source form are |
237 | 1393 detected, then the file is assumed to be in fixed source form. The algorithm |
1394 should work in the vast majority of cases. In some cases, such as a file that | |
819 | 1395 begins with 250 or more full-line comments, the script may incorrectly decide |
237 | 1396 that the fortran code is in fixed form. If that happens, just add a |
7 | 1397 non-comment statement beginning anywhere in the first five columns of the |
1398 first twenty five lines, save (:w) and then reload (:e!) the file. | |
1399 | |
1400 Tabs in fortran files ~ | |
237 | 1401 Tabs are not recognized by the Fortran standards. Tabs are not a good idea in |
7 | 1402 fixed format fortran source code which requires fixed column boundaries. |
237 | 1403 Therefore, tabs are marked as errors. Nevertheless, some programmers like |
1404 using tabs. If your fortran files contain tabs, then you should set the | |
7 | 1405 variable fortran_have_tabs in your .vimrc with a command such as > |
1406 :let fortran_have_tabs=1 | |
237 | 1407 placed prior to the :syntax on command. Unfortunately, the use of tabs will |
7 | 1408 mean that the syntax file will not be able to detect incorrect margins. |
1409 | |
1410 Syntax folding of fortran files ~ | |
1411 If you wish to use foldmethod=syntax, then you must first set the variable | |
1412 fortran_fold with a command such as > | |
1413 :let fortran_fold=1 | |
1414 to instruct the syntax script to define fold regions for program units, that | |
1415 is main programs starting with a program statement, subroutines, function | |
237 | 1416 subprograms, block data subprograms, interface blocks, and modules. If you |
7 | 1417 also set the variable fortran_fold_conditionals with a command such as > |
1418 :let fortran_fold_conditionals=1 | |
1419 then fold regions will also be defined for do loops, if blocks, and select | |
237 | 1420 case constructs. If you also set the variable |
7 | 1421 fortran_fold_multilinecomments with a command such as > |
1422 :let fortran_fold_multilinecomments=1 | |
1423 then fold regions will also be defined for three or more consecutive comment | |
237 | 1424 lines. Note that defining fold regions can be slow for large files. |
7 | 1425 |
1426 If fortran_fold, and possibly fortran_fold_conditionals and/or | |
1427 fortran_fold_multilinecomments, have been set, then vim will fold your file if | |
237 | 1428 you set foldmethod=syntax. Comments or blank lines placed between two program |
7 | 1429 units are not folded because they are seen as not belonging to any program |
1430 unit. | |
1431 | |
1432 More precise fortran syntax ~ | |
1433 If you set the variable fortran_more_precise with a command such as > | |
1434 :let fortran_more_precise=1 | |
237 | 1435 then the syntax coloring will be more precise but slower. In particular, |
7 | 1436 statement labels used in do, goto and arithmetic if statements will be |
1437 recognized, as will construct names at the end of a do, if, select or forall | |
1438 construct. | |
1439 | |
1440 Non-default fortran dialects ~ | |
3281 | 1441 The syntax script supports two Fortran dialects: f08 and F. You will probably |
1442 find the default highlighting (f08) satisfactory. A few legacy constructs | |
1443 deleted or declared obsolescent in the 2008 standard are highlighted as todo | |
1444 items. | |
1445 | |
1446 If you use F, the advantage of setting the dialect appropriately is that | |
1447 other legacy features excluded from F will be highlighted as todo items and | |
4992 | 1448 that free source form will be assumed. |
3281 | 1449 |
1450 The dialect can be selected in various ways. If all your fortran files use | |
1451 the same dialect, set the global variable fortran_dialect in your .vimrc prior | |
1452 to your syntax on statement. The case-sensitive, permissible values of | |
1453 fortran_dialect are "f08" or "F". Invalid values of fortran_dialect are | |
1454 ignored. | |
1455 | |
1456 If the dialect depends upon the file extension, then it is most convenient to | |
1457 set a buffer-local variable in a ftplugin file. For more information on | |
1458 ftplugin files, see |ftplugin|. For example, if all your fortran files with | |
1459 an .f90 extension are written in the F subset, your ftplugin file should | |
1460 contain the code > | |
7 | 1461 let s:extfname = expand("%:e") |
1462 if s:extfname ==? "f90" | |
3281 | 1463 let b:fortran_dialect="F" |
7 | 1464 else |
3281 | 1465 unlet! b:fortran_dialect |
7 | 1466 endif |
1467 Note that this will work only if the "filetype plugin indent on" command | |
1468 precedes the "syntax on" command in your .vimrc file. | |
1469 | |
1470 Finer control is necessary if the file extension does not uniquely identify | |
3281 | 1471 the dialect. You can override the default dialect, on a file-by-file basis, |
1472 by including a comment with the directive "fortran_dialect=xx" (where xx=F or | |
1473 f08) in one of the first three lines in your file. For example, your older .f | |
1474 files may be legacy code but your newer ones may be F codes, and you would | |
1475 identify the latter by including in the first three lines of those files a | |
1476 Fortran comment of the form > | |
7 | 1477 ! fortran_dialect=F |
3281 | 1478 |
1479 For previous versions of the syntax, you may have set fortran_dialect to the | |
1480 now-obsolete values "f77", "f90", "f95", or "elf". Such settings will be | |
1481 silently handled as "f08". Users of "elf" may wish to experiment with "F" | |
4992 | 1482 instead. |
3281 | 1483 |
1484 The syntax/fortran.vim script contains embedded comments that tell you how to | |
1485 comment and/or uncomment some lines to (a) activate recognition of some | |
1486 non-standard, vendor-supplied intrinsics and (b) to prevent features deleted | |
1487 or declared obsolescent in the 2008 standard from being highlighted as todo | |
4992 | 1488 items. |
7 | 1489 |
1490 Limitations ~ | |
237 | 1491 Parenthesis checking does not catch too few closing parentheses. Hollerith |
1492 strings are not recognized. Some keywords may be highlighted incorrectly | |
7 | 1493 because Fortran90 has no reserved words. |
1494 | |
501 | 1495 For further information related to fortran, see |ft-fortran-indent| and |
1496 |ft-fortran-plugin|. | |
1497 | |
1498 | |
1499 FVWM CONFIGURATION FILES *fvwm.vim* *ft-fvwm-syntax* | |
7 | 1500 |
1501 In order for Vim to recognize Fvwm configuration files that do not match | |
1502 the patterns *fvwmrc* or *fvwm2rc* , you must put additional patterns | |
1503 appropriate to your system in your myfiletypes.vim file. For these | |
1504 patterns, you must set the variable "b:fvwm_version" to the major version | |
1505 number of Fvwm, and the 'filetype' option to fvwm. | |
1506 | |
1507 For example, to make Vim identify all files in /etc/X11/fvwm2/ | |
1508 as Fvwm2 configuration files, add the following: > | |
1509 | |
1510 :au! BufNewFile,BufRead /etc/X11/fvwm2/* let b:fvwm_version = 2 | | |
1511 \ set filetype=fvwm | |
1512 | |
1513 If you'd like Vim to highlight all valid color names, tell it where to | |
1514 find the color database (rgb.txt) on your system. Do this by setting | |
1515 "rgb_file" to its location. Assuming your color database is located | |
1516 in /usr/X11/lib/X11/, you should add the line > | |
1517 | |
1518 :let rgb_file = "/usr/X11/lib/X11/rgb.txt" | |
1519 | |
1520 to your .vimrc file. | |
1521 | |
1522 | |
501 | 1523 GSP *gsp.vim* *ft-gsp-syntax* |
7 | 1524 |
1525 The default coloring style for GSP pages is defined by |html.vim|, and | |
1526 the coloring for java code (within java tags or inline between backticks) | |
1527 is defined by |java.vim|. The following HTML groups defined in |html.vim| | |
1528 are redefined to incorporate and highlight inline java code: | |
1529 | |
1530 htmlString | |
1531 htmlValue | |
1532 htmlEndTag | |
1533 htmlTag | |
1534 htmlTagN | |
1535 | |
1536 Highlighting should look fine most of the places where you'd see inline | |
1537 java code, but in some special cases it may not. To add another HTML | |
1538 group where you will have inline java code where it does not highlight | |
1539 correctly, just copy the line you want from |html.vim| and add gspJava | |
1540 to the contains clause. | |
1541 | |
1542 The backticks for inline java are highlighted according to the htmlError | |
1543 group to make them easier to see. | |
1544 | |
1545 | |
501 | 1546 GROFF *groff.vim* *ft-groff-syntax* |
7 | 1547 |
1548 The groff syntax file is a wrapper for |nroff.vim|, see the notes | |
237 | 1549 under that heading for examples of use and configuration. The purpose |
7 | 1550 of this wrapper is to set up groff syntax extensions by setting the |
1551 filetype from a |modeline| or in a personal filetype definitions file | |
1552 (see |filetype.txt|). | |
1553 | |
1554 | |
501 | 1555 HASKELL *haskell.vim* *lhaskell.vim* *ft-haskell-syntax* |
7 | 1556 |
1557 The Haskell syntax files support plain Haskell code as well as literate | |
237 | 1558 Haskell code, the latter in both Bird style and TeX style. The Haskell |
7 | 1559 syntax highlighting will also highlight C preprocessor directives. |
1560 | |
1561 If you want to highlight delimiter characters (useful if you have a | |
1562 light-coloured background), add to your .vimrc: > | |
1563 :let hs_highlight_delimiters = 1 | |
1564 To treat True and False as keywords as opposed to ordinary identifiers, | |
1565 add: > | |
1566 :let hs_highlight_boolean = 1 | |
1567 To also treat the names of primitive types as keywords: > | |
1568 :let hs_highlight_types = 1 | |
1569 And to treat the names of even more relatively common types as keywords: > | |
1570 :let hs_highlight_more_types = 1 | |
1571 If you want to highlight the names of debugging functions, put in | |
1572 your .vimrc: > | |
1573 :let hs_highlight_debug = 1 | |
1574 | |
1575 The Haskell syntax highlighting also highlights C preprocessor | |
1576 directives, and flags lines that start with # but are not valid | |
237 | 1577 directives as erroneous. This interferes with Haskell's syntax for |
1578 operators, as they may start with #. If you want to highlight those | |
7 | 1579 as operators as opposed to errors, put in your .vimrc: > |
1580 :let hs_allow_hash_operator = 1 | |
1581 | |
1582 The syntax highlighting for literate Haskell code will try to | |
1583 automatically guess whether your literate Haskell code contains | |
1584 TeX markup or not, and correspondingly highlight TeX constructs | |
237 | 1585 or nothing at all. You can override this globally by putting |
7 | 1586 in your .vimrc > |
1587 :let lhs_markup = none | |
1588 for no highlighting at all, or > | |
1589 :let lhs_markup = tex | |
1590 to force the highlighting to always try to highlight TeX markup. | |
1591 For more flexibility, you may also use buffer local versions of | |
1592 this variable, so e.g. > | |
1593 :let b:lhs_markup = tex | |
237 | 1594 will force TeX highlighting for a particular buffer. It has to be |
7 | 1595 set before turning syntax highlighting on for the buffer or |
1596 loading a file. | |
1597 | |
1598 | |
501 | 1599 HTML *html.vim* *ft-html-syntax* |
7 | 1600 |
1601 The coloring scheme for tags in the HTML file works as follows. | |
1602 | |
1603 The <> of opening tags are colored differently than the </> of a closing tag. | |
1604 This is on purpose! For opening tags the 'Function' color is used, while for | |
1605 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
1606 defined for you) | |
1607 | |
1608 Known tag names are colored the same way as statements in C. Unknown tag | |
1609 names are colored with the same color as the <> or </> respectively which | |
1610 makes it easy to spot errors | |
1611 | |
237 | 1612 Note that the same is true for argument (or attribute) names. Known attribute |
7 | 1613 names are colored differently than unknown ones. |
1614 | |
237 | 1615 Some HTML tags are used to change the rendering of text. The following tags |
7 | 1616 are recognized by the html.vim syntax coloring file and change the way normal |
1617 text is shown: <B> <I> <U> <EM> <STRONG> (<EM> is used as an alias for <I>, | |
1618 while <STRONG> as an alias for <B>), <H1> - <H6>, <HEAD>, <TITLE> and <A>, but | |
237 | 1619 only if used as a link (that is, it must include a href as in |
1224 | 1620 <A href="somefile.html">). |
7 | 1621 |
1622 If you want to change how such text is rendered, you must redefine the | |
1623 following syntax groups: | |
1624 | |
1625 - htmlBold | |
1626 - htmlBoldUnderline | |
1627 - htmlBoldUnderlineItalic | |
1628 - htmlUnderline | |
1629 - htmlUnderlineItalic | |
1630 - htmlItalic | |
1631 - htmlTitle for titles | |
1632 - htmlH1 - htmlH6 for headings | |
1633 | |
1634 To make this redefinition work you must redefine them all with the exception | |
1635 of the last two (htmlTitle and htmlH[1-6], which are optional) and define the | |
1636 following variable in your vimrc (this is due to the order in which the files | |
1637 are read during initialization) > | |
1638 :let html_my_rendering=1 | |
1639 | |
1640 If you'd like to see an example download mysyntax.vim at | |
1641 http://www.fleiner.com/vim/download.html | |
1642 | |
1643 You can also disable this rendering by adding the following line to your | |
1644 vimrc file: > | |
1645 :let html_no_rendering=1 | |
1646 | |
1647 HTML comments are rather special (see an HTML reference document for the | |
1648 details), and the syntax coloring scheme will highlight all errors. | |
1649 However, if you prefer to use the wrong style (starts with <!-- and | |
1650 ends with --!>) you can define > | |
1651 :let html_wrong_comments=1 | |
1652 | |
1653 JavaScript and Visual Basic embedded inside HTML documents are highlighted as | |
1654 'Special' with statements, comments, strings and so on colored as in standard | |
237 | 1655 programming languages. Note that only JavaScript and Visual Basic are currently |
7 | 1656 supported, no other scripting language has been added yet. |
1657 | |
1658 Embedded and inlined cascading style sheets (CSS) are highlighted too. | |
1659 | |
237 | 1660 There are several html preprocessor languages out there. html.vim has been |
1661 written such that it should be trivial to include it. To do so add the | |
7 | 1662 following two lines to the syntax coloring file for that language |
1663 (the example comes from the asp.vim file): | |
1664 | |
1665 runtime! syntax/html.vim | |
1666 syn cluster htmlPreproc add=asp | |
1667 | |
1668 Now you just need to make sure that you add all regions that contain | |
1669 the preprocessor language to the cluster htmlPreproc. | |
1670 | |
1671 | |
501 | 1672 HTML/OS (by Aestiva) *htmlos.vim* *ft-htmlos-syntax* |
7 | 1673 |
1674 The coloring scheme for HTML/OS works as follows: | |
1675 | |
1676 Functions and variable names are the same color by default, because VIM | |
1677 doesn't specify different colors for Functions and Identifiers. To change | |
1678 this (which is recommended if you want function names to be recognizable in a | |
1679 different color) you need to add the following line to either your ~/.vimrc: > | |
1680 :hi Function term=underline cterm=bold ctermfg=LightGray | |
1681 | |
1682 Of course, the ctermfg can be a different color if you choose. | |
1683 | |
1684 Another issues that HTML/OS runs into is that there is no special filetype to | |
1685 signify that it is a file with HTML/OS coding. You can change this by opening | |
1686 a file and turning on HTML/OS syntax by doing the following: > | |
1687 :set syntax=htmlos | |
1688 | |
1689 Lastly, it should be noted that the opening and closing characters to begin a | |
1690 block of HTML/OS code can either be << or [[ and >> or ]], respectively. | |
1691 | |
1692 | |
501 | 1693 IA64 *ia64.vim* *intel-itanium* *ft-ia64-syntax* |
7 | 1694 |
1695 Highlighting for the Intel Itanium 64 assembly language. See |asm.vim| for | |
1696 how to recognize this filetype. | |
1697 | |
1698 To have *.inc files be recognized as IA64, add this to your .vimrc file: > | |
1699 :let g:filetype_inc = "ia64" | |
1700 | |
1701 | |
501 | 1702 INFORM *inform.vim* *ft-inform-syntax* |
7 | 1703 |
1704 Inform highlighting includes symbols provided by the Inform Library, as | |
1705 most programs make extensive use of it. If do not wish Library symbols | |
1706 to be highlighted add this to your vim startup: > | |
1707 :let inform_highlight_simple=1 | |
1708 | |
1709 By default it is assumed that Inform programs are Z-machine targeted, | |
1710 and highlights Z-machine assembly language symbols appropriately. If | |
1711 you intend your program to be targeted to a Glulx/Glk environment you | |
1712 need to add this to your startup sequence: > | |
1713 :let inform_highlight_glulx=1 | |
1714 | |
1715 This will highlight Glulx opcodes instead, and also adds glk() to the | |
1716 set of highlighted system functions. | |
1717 | |
1718 The Inform compiler will flag certain obsolete keywords as errors when | |
1719 it encounters them. These keywords are normally highlighted as errors | |
1720 by Vim. To prevent such error highlighting, you must add this to your | |
1721 startup sequence: > | |
1722 :let inform_suppress_obsolete=1 | |
1723 | |
1724 By default, the language features highlighted conform to Compiler | |
1725 version 6.30 and Library version 6.11. If you are using an older | |
1726 Inform development environment, you may with to add this to your | |
1727 startup sequence: > | |
1728 :let inform_highlight_old=1 | |
1729 | |
829 | 1730 IDL *idl.vim* *idl-syntax* |
1731 | |
1732 IDL (Interface Definition Language) files are used to define RPC calls. In | |
1733 Microsoft land, this is also used for defining COM interfaces and calls. | |
1734 | |
1735 IDL's structure is simple enough to permit a full grammar based approach to | |
1736 rather than using a few heuristics. The result is large and somewhat | |
1224 | 1737 repetitive but seems to work. |
829 | 1738 |
1739 There are some Microsoft extensions to idl files that are here. Some of them | |
1740 are disabled by defining idl_no_ms_extensions. | |
1741 | |
1742 The more complex of the extensions are disabled by defining idl_no_extensions. | |
1743 | |
1744 Variable Effect ~ | |
1745 | |
1746 idl_no_ms_extensions Disable some of the Microsoft specific | |
1747 extensions | |
1748 idl_no_extensions Disable complex extensions | |
1749 idlsyntax_showerror Show IDL errors (can be rather intrusive, but | |
1750 quite helpful) | |
1751 idlsyntax_showerror_soft Use softer colours by default for errors | |
1752 | |
7 | 1753 |
501 | 1754 JAVA *java.vim* *ft-java-syntax* |
7 | 1755 |
1756 The java.vim syntax highlighting file offers several options: | |
1757 | |
1758 In Java 1.0.2 it was never possible to have braces inside parens, so this was | |
1759 flagged as an error. Since Java 1.1 this is possible (with anonymous | |
237 | 1760 classes), and therefore is no longer marked as an error. If you prefer the old |
7 | 1761 way, put the following line into your vim startup file: > |
1762 :let java_mark_braces_in_parens_as_errors=1 | |
1763 | |
1764 All identifiers in java.lang.* are always visible in all classes. To | |
1765 highlight them use: > | |
1766 :let java_highlight_java_lang_ids=1 | |
1767 | |
237 | 1768 You can also highlight identifiers of most standard Java packages if you |
7 | 1769 download the javaid.vim script at http://www.fleiner.com/vim/download.html. |
1770 If you prefer to only highlight identifiers of a certain package, say java.io | |
1771 use the following: > | |
1772 :let java_highlight_java_io=1 | |
1773 Check the javaid.vim file for a list of all the packages that are supported. | |
1774 | |
1775 Function names are not highlighted, as the way to find functions depends on | |
237 | 1776 how you write Java code. The syntax file knows two possible ways to highlight |
7 | 1777 functions: |
1778 | |
1779 If you write function declarations that are always indented by either | |
1780 a tab, 8 spaces or 2 spaces you may want to set > | |
1781 :let java_highlight_functions="indent" | |
1782 However, if you follow the Java guidelines about how functions and classes are | |
1783 supposed to be named (with respect to upper and lowercase), use > | |
1784 :let java_highlight_functions="style" | |
1785 If both options do not work for you, but you would still want function | |
1786 declarations to be highlighted create your own definitions by changing the | |
1787 definitions in java.vim or by creating your own java.vim which includes the | |
1788 original one and then adds the code to highlight functions. | |
1789 | |
237 | 1790 In Java 1.1 the functions System.out.println() and System.err.println() should |
8 | 1791 only be used for debugging. Therefore it is possible to highlight debugging |
237 | 1792 statements differently. To do this you must add the following definition in |
7 | 1793 your startup file: > |
1794 :let java_highlight_debug=1 | |
1795 The result will be that those statements are highlighted as 'Special' | |
237 | 1796 characters. If you prefer to have them highlighted differently you must define |
7 | 1797 new highlightings for the following groups.: |
1798 Debug, DebugSpecial, DebugString, DebugBoolean, DebugType | |
1799 which are used for the statement itself, special characters used in debug | |
237 | 1800 strings, strings, boolean constants and types (this, super) respectively. I |
7 | 1801 have opted to chose another background for those statements. |
1802 | |
237 | 1803 Javadoc is a program that takes special comments out of Java program files and |
1804 creates HTML pages. The standard configuration will highlight this HTML code | |
1805 similarly to HTML files (see |html.vim|). You can even add Javascript | |
1806 and CSS inside this code (see below). There are four differences however: | |
7 | 1807 1. The title (all characters up to the first '.' which is followed by |
1808 some white space or up to the first '@') is colored differently (to change | |
1809 the color change the group CommentTitle). | |
1810 2. The text is colored as 'Comment'. | |
1811 3. HTML comments are colored as 'Special' | |
237 | 1812 4. The special Javadoc tags (@see, @param, ...) are highlighted as specials |
7 | 1813 and the argument (for @see, @param, @exception) as Function. |
1814 To turn this feature off add the following line to your startup file: > | |
1815 :let java_ignore_javadoc=1 | |
1816 | |
237 | 1817 If you use the special Javadoc comment highlighting described above you |
1818 can also turn on special highlighting for Javascript, visual basic | |
1819 scripts and embedded CSS (stylesheets). This makes only sense if you | |
1820 actually have Javadoc comments that include either Javascript or embedded | |
1821 CSS. The options to use are > | |
7 | 1822 :let java_javascript=1 |
1823 :let java_css=1 | |
1824 :let java_vb=1 | |
1825 | |
1826 In order to highlight nested parens with different colors define colors | |
1827 for javaParen, javaParen1 and javaParen2, for example with > | |
1828 :hi link javaParen Comment | |
1829 or > | |
1830 :hi javaParen ctermfg=blue guifg=#0000ff | |
1831 | |
1832 If you notice highlighting errors while scrolling backwards, which are fixed | |
1833 when redrawing with CTRL-L, try setting the "java_minlines" internal variable | |
1834 to a larger number: > | |
1835 :let java_minlines = 50 | |
1836 This will make the syntax synchronization start 50 lines before the first | |
1837 displayed line. The default value is 10. The disadvantage of using a larger | |
1838 number is that redrawing can become slow. | |
1839 | |
1840 | |
501 | 1841 LACE *lace.vim* *ft-lace-syntax* |
7 | 1842 |
1843 Lace (Language for Assembly of Classes in Eiffel) is case insensitive, but the | |
1844 style guide lines are not. If you prefer case insensitive highlighting, just | |
1845 define the vim variable 'lace_case_insensitive' in your startup file: > | |
1846 :let lace_case_insensitive=1 | |
1847 | |
1848 | |
501 | 1849 LEX *lex.vim* *ft-lex-syntax* |
7 | 1850 |
1851 Lex uses brute-force synchronizing as the "^%%$" section delimiter | |
1852 gives no clue as to what section follows. Consequently, the value for > | |
1853 :syn sync minlines=300 | |
1854 may be changed by the user if s/he is experiencing synchronization | |
1855 difficulties (such as may happen with large lex files). | |

555 | 1865 LISP *lisp.vim* *ft-lisp-syntax* |
1866 | |
1867 The lisp syntax highlighting provides two options: > | |
1868 | |
1869 g:lisp_instring : if it exists, then "(...)" strings are highlighted | |
1870 as if the contents of the string were lisp. | |
1871 Useful for AutoLisp. | |
1872 g:lisp_rainbow : if it exists and is nonzero, then differing levels | |
1873 of parenthesization will receive different | |
1874 highlighting. | |
1875 < | |
1876 The g:lisp_rainbow option provides 10 levels of individual colorization for | |
1877 the parentheses and backquoted parentheses. Because of the quantity of | |
1878 colorization levels, unlike non-rainbow highlighting, the rainbow mode | |
1879 specifies its highlighting using ctermfg and guifg, thereby bypassing the | |
1880 usual colorscheme control using standard highlighting groups. The actual | |
1881 highlighting used depends on the dark/bright setting (see |'bg'|). | |
1882 | |
1883 | |

1889 | |
1890 :let lite_sql_query = 1 | |
1891 | |
1892 For syncing, minlines defaults to 100. If you prefer another value, you can | |
1893 set "lite_minlines" to the value you desire. Example: > | |
1894 | |
1895 :let lite_minlines = 200 | |
1896 | |
1897 | |
501 | 1898 LPC *lpc.vim* *ft-lpc-syntax* |
7 | 1899 |
237 | 1900 LPC stands for a simple, memory-efficient language: Lars Pensj| C. The |
7 | 1901 file name of LPC is usually *.c. Recognizing these files as LPC would bother |
1902 users writing only C programs. If you want to use LPC syntax in Vim, you | |
1903 should set a variable in your .vimrc file: > | |
1904 | |
1905 :let lpc_syntax_for_c = 1 | |
1906 | |
1907 If it doesn't work properly for some particular C or LPC files, use a | |
1908 modeline. For a LPC file: | |
1909 | |
1910 // vim:set ft=lpc: | |
1911 | |
1912 For a C file that is recognized as LPC: | |
1913 | |
1914 // vim:set ft=c: | |
1915 | |
1916 If you don't want to set the variable, use the modeline in EVERY LPC file. | |
1917 | |
1918 There are several implementations for LPC, we intend to support most widely | |
237 | 1919 used ones. Here the default LPC syntax is for MudOS series, for MudOS v22 |
7 | 1920 and before, you should turn off the sensible modifiers, and this will also |
1921 asserts the new efuns after v22 to be invalid, don't set this variable when | |
1922 you are using the latest version of MudOS: > | |
1923 | |
1924 :let lpc_pre_v22 = 1 | |
1925 | |
1926 For LpMud 3.2 series of LPC: > | |
1927 | |
1928 :let lpc_compat_32 = 1 | |
1929 | |
1930 For LPC4 series of LPC: > | |
1931 | |
1932 :let lpc_use_lpc4_syntax = 1 | |
1933 | |
1934 For uLPC series of LPC: | |
1935 uLPC has been developed to Pike, so you should use Pike syntax | |
1936 instead, and the name of your source file should be *.pike | |
1937 | |
1938 | |
501 | 1939 LUA *lua.vim* *ft-lua-syntax* |
7 | 1940 |
3356 | 1941 The Lua syntax file can be used for versions 4.0, 5.0, 5.1 and 5.2 (5.2 is |
838 | 1942 the default). You can select one of these versions using the global variables |
1943 lua_version and lua_subversion. For example, to activate Lua | |
3356 | 1944 5.1 syntax highlighting, set the variables like this: |
838 | 1945 |
1946 :let lua_version = 5 | |
1947 :let lua_subversion = 1 | |
7 | 1948 |
1949 | |
501 | 1950 MAIL *mail.vim* *ft-mail.vim* |
7 | 1951 |
1952 Vim highlights all the standard elements of an email (headers, signatures, | |
237 | 1953 quoted text and URLs / email addresses). In keeping with standard conventions, |
7 | 1954 signatures begin in a line containing only "--" followed optionally by |
1955 whitespaces and end with a newline. | |
1956 | |
1957 Vim treats lines beginning with ']', '}', '|', '>' or a word followed by '>' | |
237 | 1958 as quoted text. However Vim highlights headers and signatures in quoted text |
7 | 1959 only if the text is quoted with '>' (optionally followed by one space). |
1960 | |
1961 By default mail.vim synchronises syntax to 100 lines before the first | |
237 | 1962 displayed line. If you have a slow machine, and generally deal with emails |
7 | 1963 with short headers, you can change this to a smaller value: > |
1964 | |
1965 :let mail_minlines = 30 | |
1966 | |
1967 | |
501 | 1968 MAKE *make.vim* *ft-make-syntax* |
7 | 1969 |
1970 In makefiles, commands are usually highlighted to make it easy for you to spot | |
1971 errors. However, this may be too much coloring for you. You can turn this | |
1972 feature off by using: > | |
1973 | |
1974 :let make_no_commands = 1 | |
1975 | |
1976 | |
501 | 1977 MAPLE *maple.vim* *ft-maple-syntax* |
7 | 1978 |
1979 Maple V, by Waterloo Maple Inc, supports symbolic algebra. The language | |
1980 supports many packages of functions which are selectively loaded by the user. | |
1981 The standard set of packages' functions as supplied in Maple V release 4 may be | |
1982 highlighted at the user's discretion. Users may place in their .vimrc file: > | |
1983 | |
1984 :let mvpkg_all= 1 | |
1985 | |
1986 to get all package functions highlighted, or users may select any subset by | |
1987 choosing a variable/package from the table below and setting that variable to | |
1988 1, also in their .vimrc file (prior to sourcing | |
1989 $VIMRUNTIME/syntax/syntax.vim). | |

2004 Empty *.m files will automatically be presumed to be Matlab files unless you | |
2005 have the following in your .vimrc: > | |

2008 | |
2009 | |
501 | 2010 MOO *moo.vim* *ft-moo-syntax* |
7 | 2011 |
2012 If you use C-style comments inside expressions and find it mangles your | |
2013 highlighting, you may want to use extended (slow!) matches for C-style | |
2014 comments: > | |
2015 | |
2016 :let moo_extended_cstyle_comments = 1 | |

2032 | |
2033 :let moo_builtin_properties = 1 | |
2034 | |
237 | 2035 Unknown builtin functions can be recognized and highlighted as errors. If you |
7 | 2036 use this option, add your own extensions to the mooKnownBuiltinFunction group. |
2037 To enable this option: > | |
2038 | |
2039 :let moo_unknown_builtin_functions = 1 | |
2040 | |

2045 | |
501 | 2046 MSQL *msql.vim* *ft-msql-syntax* |
7 | 2047 |
2048 There are two options for the msql syntax highlighting. | |
2049 | |
2050 If you like SQL syntax highlighting inside Strings, use this: > | |
2051 | |
2052 :let msql_sql_query = 1 | |
2053 | |
2054 For syncing, minlines defaults to 100. If you prefer another value, you can | |
2055 set "msql_minlines" to the value you desire. Example: > | |
2056 | |
2057 :let msql_minlines = 200 | |
2058 | |
2059 | |
501 | 2060 NCF *ncf.vim* *ft-ncf-syntax* |
7 | 2061 |
2062 There is one option for NCF syntax highlighting. | |
2063 | |
2064 If you want to have unrecognized (by ncf.vim) statements highlighted as | |
2065 errors, use this: > | |
2066 | |
2067 :let ncf_highlight_unknowns = 1 | |
2068 | |
2069 If you don't want to highlight these errors, leave it unset. | |
2070 | |
2071 | |
501 | 2072 NROFF *nroff.vim* *ft-nroff-syntax* |
7 | 2073 |
2074 The nroff syntax file works with AT&T n/troff out of the box. You need to | |
2075 activate the GNU groff extra features included in the syntax file before you | |
2076 can use them. | |
2077 | |
2078 For example, Linux and BSD distributions use groff as their default text | |
237 | 2079 processing package. In order to activate the extra syntax highlighting |
7 | 2080 features for groff, add the following option to your start-up files: > |
2081 | |
2082 :let b:nroff_is_groff = 1 | |
2083 | |
2084 Groff is different from the old AT&T n/troff that you may still find in | |
2085 Solaris. Groff macro and request names can be longer than 2 characters and | |
2086 there are extensions to the language primitives. For example, in AT&T troff | |
237 | 2087 you access the year as a 2-digit number with the request \(yr. In groff you |
7 | 2088 can use the same request, recognized for compatibility, or you can use groff's |
2089 native syntax, \[yr]. Furthermore, you can use a 4-digit year directly: | |
2090 \[year]. Macro requests can be longer than 2 characters, for example, GNU mm | |
2091 accepts the requests ".VERBON" and ".VERBOFF" for creating verbatim | |
2092 environments. | |
2093 | |
2094 In order to obtain the best formatted output g/troff can give you, you should | |
2095 follow a few simple rules about spacing and punctuation. | |
2096 | |
2097 1. Do not leave empty spaces at the end of lines. | |
2098 | |
2099 2. Leave one space and one space only after an end-of-sentence period, | |
2100 exclamation mark, etc. | |
2101 | |
2102 3. For reasons stated below, it is best to follow all period marks with a | |
2103 carriage return. | |
2104 | |
2105 The reason behind these unusual tips is that g/n/troff have a line breaking | |
2106 algorithm that can be easily upset if you don't follow the rules given above. | |
2107 | |
2108 Unlike TeX, troff fills text line-by-line, not paragraph-by-paragraph and, | |
2109 furthermore, it does not have a concept of glue or stretch, all horizontal and | |
2110 vertical space input will be output as is. | |
2111 | |
2112 Therefore, you should be careful about not using more space between sentences | |
2113 than you intend to have in your final document. For this reason, the common | |
2114 practice is to insert a carriage return immediately after all punctuation | |
237 | 2115 marks. If you want to have "even" text in your final processed output, you |
4264 | 2116 need to maintain regular spacing in the input text. To mark both trailing |
7 | 2117 spaces and two or more spaces after a punctuation as an error, use: > |
2118 | |
2119 :let nroff_space_errors = 1 | |
2120 | |
2121 Another technique to detect extra spacing and other errors that will interfere | |
2122 with the correct typesetting of your file, is to define an eye-catching | |
2123 highlighting definition for the syntax groups "nroffDefinition" and | |
237 | 2124 "nroffDefSpecial" in your configuration files. For example: > |
7 | 2125 |
2126 hi def nroffDefinition term=italic cterm=italic gui=reverse | |
2127 hi def nroffDefSpecial term=italic,bold cterm=italic,bold | |
2128 \ gui=reverse,bold | |
2129 | |
2130 If you want to navigate preprocessor entries in your source file as easily as | |
2131 with section markers, you can activate the following option in your .vimrc | |
2132 file: > | |
2133 | |
2134 let b:preprocs_as_sections = 1 | |
2135 | |
9 | 2136 As well, the syntax file adds an extra paragraph marker for the extended |
7 | 2137 paragraph macro (.XP) in the ms package. |
2138 | |
2139 Finally, there is a |groff.vim| syntax file that can be used for enabling | |
2140 groff syntax highlighting either on a file basis or globally by default. | |
2141 | |
2142 | |
501 | 2143 OCAML *ocaml.vim* *ft-ocaml-syntax* |
7 | 2144 |
2145 The OCaml syntax file handles files having the following prefixes: .ml, | |
2146 .mli, .mll and .mly. By setting the following variable > | |
2147 | |
2148 :let ocaml_revised = 1 | |
2149 | |
2150 you can switch from standard OCaml-syntax to revised syntax as supported | |
2151 by the camlp4 preprocessor. Setting the variable > | |
2152 | |
2153 :let ocaml_noend_error = 1 | |
2154 | |
2155 prevents highlighting of "end" as error, which is useful when sources | |
2156 contain very long structures that Vim does not synchronize anymore. | |
2157 | |
2158 | |
501 | 2159 PAPP *papp.vim* *ft-papp-syntax* |
7 | 2160 |
2161 The PApp syntax file handles .papp files and, to a lesser extend, .pxml | |
2162 and .pxsl files which are all a mixture of perl/xml/html/other using xml | |
237 | 2163 as the top-level file format. By default everything inside phtml or pxml |
2164 sections is treated as a string with embedded preprocessor commands. If | |
7 | 2165 you set the variable: > |
2166 | |
2167 :let papp_include_html=1 | |
2168 | |
2169 in your startup file it will try to syntax-hilight html code inside phtml | |
2170 sections, but this is relatively slow and much too colourful to be able to | |
237 | 2171 edit sensibly. ;) |
7 | 2172 |
2173 The newest version of the papp.vim syntax file can usually be found at | |
2174 http://papp.plan9.de. | |
2175 | |
2176 | |
501 | 2177 PASCAL *pascal.vim* *ft-pascal-syntax* |
7 | 2178 |
2179 Files matching "*.p" could be Progress or Pascal. If the automatic detection | |
2180 doesn't work for you, or you don't edit Progress at all, use this in your | |
2181 startup vimrc: > | |
2182 | |
2183 :let filetype_p = "pascal" | |
2184 | |
2185 The Pascal syntax file has been extended to take into account some extensions | |
2186 provided by Turbo Pascal, Free Pascal Compiler and GNU Pascal Compiler. | |
237 | 2187 Delphi keywords are also supported. By default, Turbo Pascal 7.0 features are |
7 | 2188 enabled. If you prefer to stick with the standard Pascal keywords, add the |
2189 following line to your startup file: > | |
2190 | |
2191 :let pascal_traditional=1 | |
2192 | |
2193 To switch on Delphi specific constructions (such as one-line comments, | |
2194 keywords, etc): > | |
2195 | |
2196 :let pascal_delphi=1 | |
2197 | |
2198 | |
2199 The option pascal_symbol_operator controls whether symbol operators such as +, | |
2200 *, .., etc. are displayed using the Operator color or not. To colorize symbol | |
2201 operators, add the following line to your startup file: > | |
2202 | |
2203 :let pascal_symbol_operator=1 | |
2204 | |
2205 Some functions are highlighted by default. To switch it off: > | |
2206 | |
2207 :let pascal_no_functions=1 | |
2208 | |

2209 Furthermore, there are specific variables for some compilers. Besides |
7 | 2210 pascal_delphi, there are pascal_gpc and pascal_fpc. Default extensions try to |
2211 match Turbo Pascal. > | |
2212 | |

2220 pascal_one_line_string variable. > | |
2221 | |
2222 :let pascal_one_line_string=1 | |
2223 | |
2224 If you dislike <Tab> chars, you can set the pascal_no_tabs variable. Tabs | |
2225 will be highlighted as Error. > | |

2230 | |
501 | 2231 PERL *perl.vim* *ft-perl-syntax* |
7 | 2232 |
2233 There are a number of possible options to the perl syntax highlighting. | |
2234 | |
4992 | 2235 Inline POD highlighting is now turned on by default. If you don't wish |
2236 to have the added complexity of highlighting POD embedded within Perl | |
2237 files, you may set the 'perl_include_pod' option to 0: > | |
2238 | |
2239 :let perl_include_pod = 0 | |
7 | 2240 |
22 | 2241 The reduce the complexity of parsing (and increase performance) you can switch |
2242 off two elements in the parsing of variable names and contents. > | |
2243 | |
2244 To handle package references in variable and function names not differently | |
2245 from the rest of the name (like 'PkgName::' in '$PkgName::VarName'): > | |
2246 | |
2247 :let perl_no_scope_in_variables = 1 | |
2248 | |
2249 (In Vim 6.x it was the other way around: "perl_want_scope_in_variables" | |
2250 enabled it.) | |
2251 | |
2252 If you do not want complex things like '@{${"foo"}}' to be parsed: > | |
2253 | |
2254 :let perl_no_extended_vars = 1 | |
2255 | |
26 | 2256 (In Vim 6.x it was the other way around: "perl_extended_vars" enabled it.) |
7 | 2257 |
237 | 2258 The coloring strings can be changed. By default strings and qq friends will be |
2259 highlighted like the first line. If you set the variable | |
7 | 2260 perl_string_as_statement, it will be highlighted as in the second line. |
2261 | |
2262 "hello world!"; qq|hello world|; | |
2263 ^^^^^^^^^^^^^^NN^^^^^^^^^^^^^^^N (unlet perl_string_as_statement) | |
2264 S^^^^^^^^^^^^SNNSSS^^^^^^^^^^^SN (let perl_string_as_statement) | |
2265 | |
2266 (^ = perlString, S = perlStatement, N = None at all) | |
2267 | |
237 | 2268 The syncing has 3 options. The first two switch off some triggering of |
7 | 2269 synchronization and should only be needed in case it fails to work properly. |
2270 If while scrolling all of a sudden the whole screen changes color completely | |
237 | 2271 then you should try and switch off one of those. Let me know if you can figure |
7 | 2272 out the line that causes the mistake. |
2273 | |
2274 One triggers on "^\s*sub\s*" and the other on "^[$@%]" more or less. > | |
2275 | |
2276 :let perl_no_sync_on_sub | |
2277 :let perl_no_sync_on_global_var | |
2278 | |
2279 Below you can set the maximum distance VIM should look for starting points for | |
2280 its attempts in syntax highlighting. > | |
2281 | |
2282 :let perl_sync_dist = 100 | |
2283 | |
2284 If you want to use folding with perl, set perl_fold: > | |
2285 | |
22 | 2286 :let perl_fold = 1 |
2287 | |
2288 If you want to fold blocks in if statements, etc. as well set the following: > | |
2289 | |
2290 :let perl_fold_blocks = 1 | |
7 | 2291 |
4992 | 2292 Subroutines are folded by default if 'perl_fold' is set. If you do not want |
2293 this, you can set 'perl_nofold_subs': > | |
2294 | |
2295 :let perl_nofold_subs = 1 | |
2296 | |
2297 Anonymous subroutines are not folded by default; you may enable their folding | |
2298 via 'perl_fold_anonymous_subs': > | |
2299 | |
2300 :let perl_fold_anonymous_subs = 1 | |
2301 | |
2302 Packages are also folded by default if 'perl_fold' is set. To disable this | |
2303 behavior, set 'perl_nofold_packages': > | |
2304 | |
2305 :let perl_nofold_packages = 1 | |

2342 For skipping a php end tag, if there exists an open ( or [ without a closing |
7 | 2343 one: > |
2344 | |
2345 let php_parent_error_open = 1 | |

2351 Selecting syncing method: > | |
2352 | |
2353 let php_sync_method = x | |
2354 | |
2355 x = -1 to sync by search (default), | |
2356 x > 0 to sync at least x lines backwards, | |
2357 x = 0 to sync from start. | |
2358 | |
2359 | |
816 | 2360 PLAINTEX *plaintex.vim* *ft-plaintex-syntax* |
2361 | |
2362 TeX is a typesetting language, and plaintex is the file type for the "plain" | |
2363 variant of TeX. If you never want your *.tex files recognized as plain TeX, | |
856 | 2364 see |ft-tex-plugin|. |
816 | 2365 |
2366 This syntax file has the option > | |
2367 | |
2368 let g:plaintex_delimiters = 1 | |
2369 | |
2370 if you want to highlight brackets "[]" and braces "{}". | |
2371 | |
2372 | |
501 | 2373 PPWIZARD *ppwiz.vim* *ft-ppwiz-syntax* |
7 | 2374 |
2375 PPWizard is a preprocessor for HTML and OS/2 INF files | |
2376 | |
2377 This syntax file has the options: | |
2378 | |
2379 - ppwiz_highlight_defs : determines highlighting mode for PPWizard's | |
237 | 2380 definitions. Possible values are |
7 | 2381 |
2382 ppwiz_highlight_defs = 1 : PPWizard #define statements retain the | |
237 | 2383 colors of their contents (e.g. PPWizard macros and variables) |
7 | 2384 |
2385 ppwiz_highlight_defs = 2 : preprocessor #define and #evaluate | |
2386 statements are shown in a single color with the exception of line | |
2387 continuation symbols | |
2388 | |
2389 The default setting for ppwiz_highlight_defs is 1. | |
2390 | |
2391 - ppwiz_with_html : If the value is 1 (the default), highlight literal | |
2392 HTML code; if 0, treat HTML code like ordinary text. | |
2393 | |
2394 | |
501 | 2395 PHTML *phtml.vim* *ft-phtml-syntax* |
7 | 2396 |
2397 There are two options for the phtml syntax highlighting. | |
2398 | |
2399 If you like SQL syntax highlighting inside Strings, use this: > | |
2400 | |
2401 :let phtml_sql_query = 1 | |
2402 | |
2403 For syncing, minlines defaults to 100. If you prefer another value, you can | |
2404 set "phtml_minlines" to the value you desire. Example: > | |
2405 | |
2406 :let phtml_minlines = 200 | |
2407 | |
2408 | |
501 | 2409 POSTSCRIPT *postscr.vim* *ft-postscr-syntax* |
7 | 2410 |
2411 There are several options when it comes to highlighting PostScript. | |
2412 | |
2413 First which version of the PostScript language to highlight. There are | |
2414 currently three defined language versions, or levels. Level 1 is the original | |
2415 and base version, and includes all extensions prior to the release of level 2. | |
2416 Level 2 is the most common version around, and includes its own set of | |
2417 extensions prior to the release of level 3. Level 3 is currently the highest | |
2418 level supported. You select which level of the PostScript language you want | |
2419 highlighted by defining the postscr_level variable as follows: > | |
2420 | |
2421 :let postscr_level=2 | |
2422 | |
2423 If this variable is not defined it defaults to 2 (level 2) since this is | |
2424 the most prevalent version currently. | |
2425 | |
2426 Note, not all PS interpreters will support all language features for a | |
2427 particular language level. In particular the %!PS-Adobe-3.0 at the start of | |
2428 PS files does NOT mean the PostScript present is level 3 PostScript! | |
2429 | |
2430 If you are working with Display PostScript, you can include highlighting of | |
2431 Display PS language features by defining the postscr_display variable as | |
2432 follows: > | |
2433 | |
2434 :let postscr_display=1 | |
2435 | |
2436 If you are working with Ghostscript, you can include highlighting of | |
2437 Ghostscript specific language features by defining the variable | |
2438 postscr_ghostscript as follows: > | |
2439 | |
2440 :let postscr_ghostscript=1 | |
2441 | |
2442 PostScript is a large language, with many predefined elements. While it | |
2443 useful to have all these elements highlighted, on slower machines this can | |
2444 cause Vim to slow down. In an attempt to be machine friendly font names and | |
2445 character encodings are not highlighted by default. Unless you are working | |
2446 explicitly with either of these this should be ok. If you want them to be | |
2447 highlighted you should set one or both of the following variables: > | |
2448 | |
2449 :let postscr_fonts=1 | |
2450 :let postscr_encodings=1 | |
2451 | |
2452 There is a stylistic option to the highlighting of and, or, and not. In | |
2453 PostScript the function of these operators depends on the types of their | |
2454 operands - if the operands are booleans then they are the logical operators, | |
2455 if they are integers then they are binary operators. As binary and logical | |
2456 operators can be highlighted differently they have to be highlighted one way | |
2457 or the other. By default they are treated as logical operators. They can be | |
2458 highlighted as binary operators by defining the variable | |
2459 postscr_andornot_binary as follows: > | |
2460 | |
2461 :let postscr_andornot_binary=1 | |
2462 < | |
2463 | |
501 | 2464 *ptcap.vim* *ft-printcap-syntax* |
2465 PRINTCAP + TERMCAP *ft-ptcap-syntax* *ft-termcap-syntax* | |
7 | 2466 |
2467 This syntax file applies to the printcap and termcap databases. | |
2468 | |
2469 In order for Vim to recognize printcap/termcap files that do not match | |
2470 the patterns *printcap*, or *termcap*, you must put additional patterns | |
2471 appropriate to your system in your |myfiletypefile| file. For these | |
2472 patterns, you must set the variable "b:ptcap_type" to either "print" or | |
2473 "term", and then the 'filetype' option to ptcap. | |
2474 | |
2475 For example, to make Vim identify all files in /etc/termcaps/ as termcap | |
2476 files, add the following: > | |
2477 | |
2478 :au BufNewFile,BufRead /etc/termcaps/* let b:ptcap_type = "term" | | |
2479 \ set filetype=ptcap | |
2480 | |
2481 If you notice highlighting errors while scrolling backwards, which | |
2482 are fixed when redrawing with CTRL-L, try setting the "ptcap_minlines" | |
2483 internal variable to a larger number: > | |
2484 | |
2485 :let ptcap_minlines = 50 | |
2486 | |
2487 (The default is 20 lines.) | |
2488 | |
2489 | |
501 | 2490 PROGRESS *progress.vim* *ft-progress-syntax* |
7 | 2491 |
2492 Files matching "*.w" could be Progress or cweb. If the automatic detection | |
2493 doesn't work for you, or you don't edit cweb at all, use this in your | |
2494 startup vimrc: > | |
2495 :let filetype_w = "progress" | |
2496 The same happens for "*.i", which could be assembly, and "*.p", which could be | |
2497 Pascal. Use this if you don't use assembly and Pascal: > | |
2498 :let filetype_i = "progress" | |
2499 :let filetype_p = "progress" | |
2500 | |
2501 | |
501 | 2502 PYTHON *python.vim* *ft-python-syntax* |
7 | 2503 |
4186 | 2504 There are six options to control Python syntax highlighting. |
7 | 2505 |
2506 For highlighted numbers: > | |
4186 | 2507 :let python_no_number_highlight = 1 |
7 | 2508 |
2509 For highlighted builtin functions: > | |
4186 | 2510 :let python_no_builtin_highlight = 1 |
7 | 2511 |
2512 For highlighted standard exceptions: > | |
4186 | 2513 :let python_no_exception_highlight = 1 |
2514 | |
2515 For highlighted doctests and code inside: > | |
2516 :let python_no_doctest_highlight = 1 | |
2517 or > | |
2518 :let python_no_doctest_code_highlight = 1 | |
2519 (first option implies second one). | |
7 | 2520 |
2596 | 2521 For highlighted trailing whitespace and mix of spaces and tabs: > |
4186 | 2522 :let python_space_error_highlight = 1 |
7 | 2523 |
2524 If you want all possible Python highlighting (the same as setting the | |
4186 | 2525 preceding last option and unsetting all other ones): > |
7 | 2526 :let python_highlight_all = 1 |
2527 | |
4992 | 2528 Note: only existence of these options matter, not their value. You can replace |
4186 | 2529 1 above with anything. |
2530 | |
7 | 2531 |
501 | 2532 QUAKE *quake.vim* *ft-quake-syntax* |
7 | 2533 |
2534 The Quake syntax definition should work for most any FPS (First Person | |
237 | 2535 Shooter) based on one of the Quake engines. However, the command names vary |
7 | 2536 a bit between the three games (Quake, Quake 2, and Quake 3 Arena) so the |
2537 syntax definition checks for the existence of three global variables to allow | |
237 | 2538 users to specify what commands are legal in their files. The three variables |
7 | 2539 can be set for the following effects: |
2540 | |
2541 set to highlight commands only available in Quake: > | |
2542 :let quake_is_quake1 = 1 | |
2543 | |
2544 set to highlight commands only available in Quake 2: > | |
2545 :let quake_is_quake2 = 1 | |
2546 | |
2547 set to highlight commands only available in Quake 3 Arena: > | |
2548 :let quake_is_quake3 = 1 | |
2549 | |
2550 Any combination of these three variables is legal, but might highlight more | |
2551 commands than are actually available to you by the game. | |
2552 | |
2553 | |
501 | 2554 READLINE *readline.vim* *ft-readline-syntax* |
7 | 2555 |
2556 The readline library is primarily used by the BASH shell, which adds quite a | |
237 | 2557 few commands and options to the ones already available. To highlight these |
7 | 2558 items as well you can add the following to your |vimrc| or just type it in the |
2559 command line before loading a file with the readline syntax: > | |
2560 let readline_has_bash = 1 | |
2561 | |
2562 This will add highlighting for the commands that BASH (version 2.05a and | |
2563 later, and part earlier) adds. | |
2564 | |
2565 | |
3920 | 2566 RESTRUCTURED TEXT *rst.vim* *ft-rst-syntax* |
2567 | |
2568 You may set what syntax definitions should be used for code blocks via | |
2569 let rst_syntax_code_list = ['vim', 'lisp', ...] | |
2570 | |
2571 | |
501 | 2572 REXX *rexx.vim* *ft-rexx-syntax* |
7 | 2573 |
2574 If you notice highlighting errors while scrolling backwards, which are fixed | |
2575 when redrawing with CTRL-L, try setting the "rexx_minlines" internal variable | |
2576 to a larger number: > | |
2577 :let rexx_minlines = 50 | |
2578 This will make the syntax synchronization start 50 lines before the first | |
2579 displayed line. The default value is 10. The disadvantage of using a larger | |
2580 number is that redrawing can become slow. | |
2581 | |
2965 | 2582 Vim tries to guess what type a ".r" file is. If it can't be detected (from |
2583 comment lines), the default is "r". To make the default rexx add this line to | |
2584 your .vimrc: *g:filetype_r* | |
2585 > | |
2586 :let g:filetype_r = "r" | |
2587 | |
7 | 2588 |
501 | 2589 RUBY *ruby.vim* *ft-ruby-syntax* |
7 | 2590 |
572 | 2591 There are a number of options to the Ruby syntax highlighting. |
7 | 2592 |
2593 By default, the "end" keyword is colorized according to the opening statement | |
572 | 2594 of the block it closes. While useful, this feature can be expensive; if you |
7 | 2595 experience slow redrawing (or you are on a terminal with poor color support) |
2596 you may want to turn it off by defining the "ruby_no_expensive" variable: > | |
572 | 2597 |
7 | 2598 :let ruby_no_expensive = 1 |
1224 | 2599 < |
7 | 2600 In this case the same color will be used for all control keywords. |
2601 | |
2602 If you do want this feature enabled, but notice highlighting errors while | |
2603 scrolling backwards, which are fixed when redrawing with CTRL-L, try setting | |
2604 the "ruby_minlines" variable to a value larger than 50: > | |
572 | 2605 |
7 | 2606 :let ruby_minlines = 100 |
1224 | 2607 < |
7 | 2608 Ideally, this value should be a number of lines large enough to embrace your |
2609 largest class or module. | |
2610 | |
1224 | 2611 Highlighting of special identifiers can be disabled by removing the |
2612 rubyIdentifier highlighting: > | |
2613 | |
2614 :hi link rubyIdentifier NONE | |
2615 < | |
7 | 2616 This will prevent highlighting of special identifiers like "ConstantName", |
572 | 2617 "$global_var", "@@class_var", "@instance_var", "| block_param |", and |
2618 ":symbol". | |
2619 | |
2620 Significant methods of Kernel, Module and Object are highlighted by default. | |
2621 This can be disabled by defining "ruby_no_special_methods": > | |
2622 | |
2623 :let ruby_no_special_methods = 1 | |
1224 | 2624 < |
572 | 2625 This will prevent highlighting of important methods such as "require", "attr", |
2626 "private", "raise" and "proc". | |
2627 | |
1224 | 2628 Ruby operators can be highlighted. This is enabled by defining |
2629 "ruby_operators": > | |
2630 | |
2631 :let ruby_operators = 1 | |
2632 < | |
572 | 2633 Whitespace errors can be highlighted by defining "ruby_space_errors": > |
2634 | |
2635 :let ruby_space_errors = 1 | |
1224 | 2636 < |
572 | 2637 This will highlight trailing whitespace and tabs preceded by a space character |
2638 as errors. This can be refined by defining "ruby_no_trail_space_error" and | |
2639 "ruby_no_tab_space_error" which will ignore trailing whitespace and tabs after | |
2640 spaces respectively. | |
2641 | |
2642 Folding can be enabled by defining "ruby_fold": > | |
2643 | |
2644 :let ruby_fold = 1 | |
1224 | 2645 < |
572 | 2646 This will set the 'foldmethod' option to "syntax" and allow folding of |
2647 classes, modules, methods, code blocks, heredocs and comments. | |
1125 | 2648 |
1224 | 2649 Folding of multiline comments can be disabled by defining |
2650 "ruby_no_comment_fold": > | |
2651 | |
2652 :let ruby_no_comment_fold = 1 | |
2653 < | |
1125 | 2654 |
501 | 2655 SCHEME *scheme.vim* *ft-scheme-syntax* |
17 | 2656 |
2657 By default only R5RS keywords are highlighted and properly indented. | |
2658 | |
2659 MzScheme-specific stuff will be used if b:is_mzscheme or g:is_mzscheme | |
2660 variables are defined. | |
856 | 2661 |
36 | 2662 Also scheme.vim supports keywords of the Chicken Scheme->C compiler. Define |
2663 b:is_chicken or g:is_chicken, if you need them. | |
17 | 2664 |
2665 | |
501 | 2666 SDL *sdl.vim* *ft-sdl-syntax* |
7 | 2667 |
2668 The SDL highlighting probably misses a few keywords, but SDL has so many | |
2669 of them it's almost impossibly to cope. | |
2670 | |
2671 The new standard, SDL-2000, specifies that all identifiers are | |
2672 case-sensitive (which was not so before), and that all keywords can be | |
237 | 2673 used either completely lowercase or completely uppercase. To have the |
7 | 2674 highlighting reflect this, you can set the following variable: > |
2675 :let sdl_2000=1 | |
2676 | |
237 | 2677 This also sets many new keywords. If you want to disable the old |
7 | 2678 keywords, which is probably a good idea, use: > |
2679 :let SDL_no_96=1 | |
2680 | |
2681 | |
2682 The indentation is probably also incomplete, but right now I am very | |
2683 satisfied with it for my own projects. | |
2684 | |
2685 | |
501 | 2686 SED *sed.vim* *ft-sed-syntax* |
7 | 2687 |
2688 To make tabs stand out from regular blanks (accomplished by using Todo | |
2689 highlighting on the tabs), define "highlight_sedtabs" by putting > | |
2690 | |
2691 :let highlight_sedtabs = 1 | |
2692 | |
2693 in the vimrc file. (This special highlighting only applies for tabs | |
2694 inside search patterns, replacement texts, addresses or text included | |
2695 by an Append/Change/Insert command.) If you enable this option, it is | |
2696 also a good idea to set the tab width to one character; by doing that, | |
2697 you can easily count the number of tabs in a string. | |
2698 | |
2699 Bugs: | |
2700 | |
2701 The transform command (y) is treated exactly like the substitute | |
2702 command. This means that, as far as this syntax file is concerned, | |
2703 transform accepts the same flags as substitute, which is wrong. | |
2704 (Transform accepts no flags.) I tolerate this bug because the | |
2705 involved commands need very complex treatment (95 patterns, one for | |
2706 each plausible pattern delimiter). | |
2707 | |
2708 | |
501 | 2709 SGML *sgml.vim* *ft-sgml-syntax* |
7 | 2710 |
2711 The coloring scheme for tags in the SGML file works as follows. | |
2712 | |
2713 The <> of opening tags are colored differently than the </> of a closing tag. | |
2714 This is on purpose! For opening tags the 'Function' color is used, while for | |
2715 closing tags the 'Type' color is used (See syntax.vim to check how those are | |
2716 defined for you) | |
2717 | |
2718 Known tag names are colored the same way as statements in C. Unknown tag | |
2719 names are not colored which makes it easy to spot errors. | |
2720 | |
237 | 2721 Note that the same is true for argument (or attribute) names. Known attribute |
7 | 2722 names are colored differently than unknown ones. |
2723 | |
237 | 2724 Some SGML tags are used to change the rendering of text. The following tags |
7 | 2725 are recognized by the sgml.vim syntax coloring file and change the way normal |
2726 text is shown: <varname> <emphasis> <command> <function> <literal> | |
2727 <replaceable> <ulink> and <link>. | |
2728 | |
2729 If you want to change how such text is rendered, you must redefine the | |
2730 following syntax groups: | |
2731 | |
2732 - sgmlBold | |
2733 - sgmlBoldItalic | |
2734 - sgmlUnderline | |
2735 - sgmlItalic | |
2736 - sgmlLink for links | |
2737 | |
2738 To make this redefinition work you must redefine them all and define the | |
2739 following variable in your vimrc (this is due to the order in which the files | |
2740 are read during initialization) > | |
2741 let sgml_my_rendering=1 | |
2742 | |
2743 You can also disable this rendering by adding the following line to your | |
2744 vimrc file: > | |
2745 let sgml_no_rendering=1 | |
2746 | |
2747 (Adapted from the html.vim help text by Claudio Fleiner <claudio@fleiner.com>) | |
2748 | |
2749 | |
501 | 2750 SH *sh.vim* *ft-sh-syntax* *ft-bash-syntax* *ft-ksh-syntax* |
7 | 2751 |
1624 | 2752 This covers the "normal" Unix (Bourne) sh, bash and the Korn shell. |
7 | 2753 |
2754 Vim attempts to determine which shell type is in use by specifying that | |
2755 various filenames are of specific types: > | |
2756 | |
2757 ksh : .kshrc* *.ksh | |
2758 bash: .bashrc* bashrc bash.bashrc .bash_profile* *.bash | |
2759 < | |
2760 If none of these cases pertain, then the first line of the file is examined | |
2761 (ex. /bin/sh /bin/ksh /bin/bash). If the first line specifies a shelltype, | |
2762 then that shelltype is used. However some files (ex. .profile) are known to | |
2763 be shell files but the type is not apparent. Furthermore, on many systems | |
828 | 2764 sh is symbolically linked to "bash" (Linux, Windows+cygwin) or "ksh" (Posix). |
7 | 2765 |
2766 One may specify a global default by instantiating one of the following three | |
2767 variables in your <.vimrc>: | |
2768 | |
2769 ksh: > | |
828 | 2770 let g:is_kornshell = 1 |
2771 < posix: (using this is the same as setting is_kornshell to 1) > | |
2772 let g:is_posix = 1 | |
7 | 2773 < bash: > |
828 | 2774 let g:is_bash = 1 |
1624 | 2775 < sh: (default) Bourne shell > |
828 | 2776 let g:is_sh = 1 |
7 | 2777 |
819 | 2778 If there's no "#! ..." line, and the user hasn't availed himself/herself of a |
2779 default sh.vim syntax setting as just shown, then syntax/sh.vim will assume | |
1624 | 2780 the Bourne shell syntax. No need to quote RFCs or market penetration |
2781 statistics in error reports, please -- just select the default version of the | |
2782 sh your system uses in your <.vimrc>. | |
2783 | |
2784 The syntax/sh.vim file provides several levels of syntax-based folding: > | |
2785 | |

2787 let g:sh_fold_enabled= 1 (enable function folding) | |

2789 let g:sh_fold_enabled= 4 (enable if/do/for folding) | |

2791 then various syntax items (HereDocuments and function bodies) become | |
1624 | 2792 syntax-foldable (see |:syn-fold|). You also may add these together |
2793 to get multiple types of folding: > | |

2797 If you notice highlighting errors while scrolling backwards which are fixed | |
2798 when one redraws with CTRL-L, try setting the "sh_minlines" internal variable | |
7 | 2799 to a larger number. Example: > |
2800 | |
2801 let sh_minlines = 500 | |
2802 | |
2803 This will make syntax synchronization start 500 lines before the first | |
2804 displayed line. The default value is 200. The disadvantage of using a larger | |
2805 number is that redrawing can become slow. | |
2806 | |
2807 If you don't have much to synchronize on, displaying can be very slow. To | |
2808 reduce this, the "sh_maxlines" internal variable can be set. Example: > | |
2809 | |
2810 let sh_maxlines = 100 | |
2811 < | |
2812 The default is to use the twice sh_minlines. Set it to a smaller number to | |
2813 speed up displaying. The disadvantage is that highlight errors may appear. | |

2849 (AspenTech plant simulator) |
7 | 2850 |
2851 The Speedup syntax file has some options: | |
2852 | |
2853 - strict_subsections : If this variable is defined, only keywords for | |
2854 sections and subsections will be highlighted as statements but not | |
2855 other keywords (like WITHIN in the OPERATION section). | |
2856 | |
2857 - highlight_types : Definition of this variable causes stream types | |
2858 like temperature or pressure to be highlighted as Type, not as a | |
237 | 2859 plain Identifier. Included are the types that are usually found in |
7 | 2860 the DECLARE section; if you defined own types, you have to include |
2861 them in the syntax file. | |
2862 | |
2863 - oneline_comments : this value ranges from 1 to 3 and determines the | |
2864 highlighting of # style comments. | |
2865 | |
2866 oneline_comments = 1 : allow normal Speedup code after an even | |
2867 number of #s. | |
2868 | |
2869 oneline_comments = 2 : show code starting with the second # as | |
237 | 2870 error. This is the default setting. |
7 | 2871 |
2872 oneline_comments = 3 : show the whole line as error if it contains | |
2873 more than one #. | |
2874 | |
2875 Since especially OPERATION sections tend to become very large due to | |
237 | 2876 PRESETting variables, syncing may be critical. If your computer is |
7 | 2877 fast enough, you can increase minlines and/or maxlines near the end of |
2878 the syntax file. | |

2884 | |
2885 While there is an ANSI standard for SQL, most database engines add their own | |
2886 custom extensions. Vim currently supports the Oracle and Informix dialects of | |
2887 SQL. Vim assumes "*.sql" files are Oracle SQL by default. | |
2888 | |
2889 Vim currently has SQL support for a variety of different vendors via syntax | |
2890 scripts. You can change Vim's default from Oracle to any of the current SQL | |
2891 supported types. You can also easily alter the SQL dialect being used on a | |
2892 buffer by buffer basis. | |

2900 for how the filetype is detected. | |
2901 | |
2902 Tcsh does not allow \" in strings unless the "backslash_quote" shell variable | |
237 | 2903 is set. If you want VIM to assume that no backslash quote constructs exist add |
7 | 2904 this line to your .vimrc: > |
2905 | |

2977 Tex: Run-on Comments or MathZones ~ |

477 | 2979 The <syntax/tex.vim> highlighting supports TeX, LaTeX, and some AmsTeX. The |
2980 highlighting supports three primary zones/regions: normal, texZone, and | |
2981 texMathZone. Although considerable effort has been made to have these zones | |
2982 terminate properly, zones delineated by $..$ and $$..$$ cannot be synchronized | |
2983 as there's no difference between start and end patterns. Consequently, a | |
7 | 2984 special "TeX comment" has been provided > |
2985 %stopzone | |

3005 | |
3006 :let g:tex_fast= "" | |
3007 | |
3008 in your .vimrc. Used this way, the g:tex_fast variable causes the syntax | |
3009 highlighting script to avoid defining any regions and associated | |
3010 synchronization. The result will be much faster syntax highlighting; the | |
3011 price: you will no longer have as much highlighting or any syntax-based | |
3012 folding, and you will be missing syntax-based error checking. | |
3013 | |
3014 You may decide that some syntax is acceptable; you may use the following table | |
3015 selectively to enable just some syntax highlighting: > | |
3016 | |
3017 b : allow bold and italic syntax | |
3018 c : allow texComment syntax | |
3019 m : allow texMatcher syntax (ie. {...} and [...]) | |

3021 p : allow parts, chapter, section, etc syntax | |
3022 r : allow texRefZone syntax (nocite, bibliography, label, pageref, eqref) | |
3023 s : allow superscript/subscript regions | |

3025 v : allow verbatim syntax | |

3036 package you'll often wish that the distributed syntax/tex.vim would support | |
3037 it. However, clearly this is impractical. So please consider using the | |
3038 techniques in |mysyntaxfile-add| to extend or modify the highlighting provided | |
3237 | 3039 by syntax/tex.vim. Please consider uploading any extensions that you write, |
3040 which typically would go in $HOME/after/syntax/tex/[pkgname].vim, to | |
3041 http://vim.sf.net/. | |

3044 Tex: Excessive Error Highlighting? ~ |
7 | 3045 |
3046 The <tex.vim> supports lexical error checking of various sorts. Thus, | |
3047 although the error checking is ofttimes very useful, it can indicate | |
3048 errors where none actually are. If this proves to be a problem for you, | |
3049 you may put in your <.vimrc> the following statement: > | |
4992 | 3050 let g:tex_no_error=1 |
477 | 3051 and all error checking by <syntax/tex.vim> will be suppressed. |

3054 Tex: Need a new Math Group? ~ |
7 | 3055 |
3056 If you want to include a new math group in your LaTeX, the following | |
3057 code shows you an example as to how you might do so: > | |
477 | 3058 call TexNewMathZone(sfx,mathzone,starform) |
3059 You'll want to provide the new math group with a unique suffix | |
3060 (currently, A-L and V-Z are taken by <syntax/tex.vim> itself). | |
3061 As an example, consider how eqnarray is set up by <syntax/tex.vim>: > | |
3062 call TexNewMathZone("D","eqnarray",1) | |
3063 You'll need to change "mathzone" to the name of your new math group, | |
3064 and then to the call to it in .vim/after/syntax/tex.vim. | |
3065 The "starform" variable, if true, implies that your new math group | |
3066 has a starred form (ie. eqnarray*). | |

3069 Tex: Starting a New Style? ~ |
7 | 3070 |
3071 One may use "\makeatletter" in *.tex files, thereby making the use of "@" in | |
3072 commands available. However, since the *.tex file doesn't have one of the | |
3073 following suffices: sty cls clo dtx ltx, the syntax highlighting will flag | |
3074 such use of @ as an error. To solve this: > | |
3075 | |
3076 :let b:tex_stylish = 1 | |
3077 :set ft=tex | |
3078 | |
3079 Putting "let g:tex_stylish=1" into your <.vimrc> will make <syntax/tex.vim> | |

3083 Tex: Taking Advantage of Conceal Mode~ |
2417 | 3084 |
2426 | 3085 If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a |
3086 number of character sequences can be translated into appropriate utf-8 glyphs, | |
3087 including various accented characters, Greek characters in MathZones, and | |
3088 superscripts and subscripts in MathZones. Not all characters can be made into | |
3089 superscripts or subscripts; the constraint is due to what utf-8 supports. | |
3090 In fact, only a few characters are supported as subscripts. | |
3091 | |
3092 One way to use this is to have vertically split windows (see |CTRL-W_v|); one | |
3093 with |'conceallevel'| at 0 and the other at 2; and both using |'scrollbind'|. | |

3113 Tex: Controlling iskeyword~ | |
3114 | |
3115 Normally, LaTeX keywords support 0-9, a-z, A-z, and 192-255 only. Latex | |
3116 keywords don't support the underscore - except when in *.sty files. The | |
3117 syntax highlighting script handles this with the following logic: | |
3118 | |
3119 * If g:tex_stylish exists and is 1 | |
3120 then the file will be treated as a "sty" file, so the "_" | |
3121 will be allowed as part of keywords | |
3122 (irregardless of g:tex_isk) | |
3123 * Else if the file's suffix is sty, cls, clo, dtx, or ltx, | |
3124 then the file will be treated as a "sty" file, so the "_" | |
3125 will be allowed as part of keywords | |
3126 (irregardless of g:tex_isk) | |
3127 | |
3128 * If g:tex_isk exists, then it will be used for the local 'iskeyword' | |
3129 * Else the local 'iskeyword' will be set to 48-57,a-z,A-Z,192-255 | |

3143 There is a trade-off between more accurate syntax highlighting versus screen |
1624 | 3144 updating speed. To improve accuracy, you may wish to increase the |
3145 g:vimsyn_minlines variable. The g:vimsyn_maxlines variable may be used to | |
3146 improve screen updating rates (see |:syn-sync| for more on this). > | |

3152 these two options) | |
3153 | |
3154 *g:vimsyn_embed* | |
3155 The g:vimsyn_embed option allows users to select what, if any, types of | |

3157 | |
3158 g:vimsyn_embed == 0 : don't embed any scripts | |
3159 g:vimsyn_embed =~ 'm' : embed mzscheme (but only if vim supports it) | |
3160 g:vimsyn_embed =~ 'p' : embed perl (but only if vim supports it) | |
3161 g:vimsyn_embed =~ 'P' : embed python (but only if vim supports it) | |
3162 g:vimsyn_embed =~ 'r' : embed ruby (but only if vim supports it) | |
3163 g:vimsyn_embed =~ 't' : embed tcl (but only if vim supports it) | |
3164 < | |
3165 By default, g:vimsyn_embed is "mpPr"; ie. syntax/vim.vim will support | |
3166 highlighting mzscheme, perl, python, and ruby by default. Vim's has("tcl") | |
3167 test appears to hang vim when tcl is not truly available. Thus, by default, | |
3168 tcl is not supported for embedding (but those of you who like tcl embedded in | |
3169 their vim syntax highlighting can simply include it in the g:vimembedscript | |
3170 option). | |
3171 *g:vimsyn_folding* | |

1624 | 3184 *g:vimsyn_noerror* |
846 | 3185 Not all error highlighting that syntax/vim.vim does may be correct; VimL is a |
3186 difficult language to highlight correctly. A way to suppress error | |
1624 | 3187 highlighting is to put the following line in your |vimrc|: > |

7 | 3194 |
3195 The syntax of XF86Config file differs in XFree86 v3.x and v4.x. Both | |
3196 variants are supported. Automatic detection is used, but is far from perfect. | |
3197 You may need to specify the version manually. Set the variable | |
3198 xf86conf_xfree86_version to 3 or 4 according to your XFree86 version in | |
3199 your .vimrc. Example: > | |
3200 :let xf86conf_xfree86_version=3 | |
3201 When using a mix of versions, set the b:xf86conf_xfree86_version variable. | |
3202 | |
3203 Note that spaces and underscores in option names are not supported. Use | |
3204 "SyncOnGreen" instead of "__s yn con gr_e_e_n" if you want the option name | |
3205 highlighted. | |

3207 | |
501 | 3208 XML *xml.vim* *ft-xml-syntax* |
7 | 3209 |
237 | 3210 Xml namespaces are highlighted by default. This can be inhibited by |

3212 | |
3213 :let g:xml_namespace_transparent=1 | |
3214 < | |
3215 *xml-folding* | |
3216 The xml syntax file provides syntax |folding| (see |:syn-fold|) between | |
237 | 3217 start and end tags. This can be turned on by > |
7 | 3218 |
3219 :let g:xml_syntax_folding = 1 | |
3220 :set foldmethod=syntax | |
3221 | |
3222 Note: syntax folding might slow down syntax highlighting significantly, | |
3223 especially for large files. | |
3224 | |
3225 | |
501 | 3226 X Pixmaps (XPM) *xpm.vim* *ft-xpm-syntax* |
7 | 3227 |
3228 xpm.vim creates its syntax items dynamically based upon the contents of the | |
3229 XPM file. Thus if you make changes e.g. in the color specification strings, | |
3230 you have to source it again e.g. with ":set syn=xpm". | |
3231 | |
3232 To copy a pixel with one of the colors, yank a "pixel" with "yl" and insert it | |
3233 somewhere else with "P". | |
3234 | |
3235 Do you want to draw with the mouse? Try the following: > | |
3236 :function! GetPixel() | |
823 | 3237 : let c = getline(".")[col(".") - 1] |
7 | 3238 : echo c |
3239 : exe "noremap <LeftMouse> <LeftMouse>r".c | |
3240 : exe "noremap <LeftDrag> <LeftMouse>r".c | |
3241 :endfunction | |
3242 :noremap <RightMouse> <LeftMouse>:call GetPixel()<CR> | |
3243 :set guicursor=n:hor20 " to see the color beneath the cursor | |
3244 This turns the right button into a pipette and the left button into a pen. | |
3245 It will work with XPM files that have one character per pixel only and you | |
3246 must not click outside of the pixel strings, but feel free to improve it. | |
3247 | |
3248 It will look much better with a font in a quadratic cell size, e.g. for X: > | |
3249 :set guifont=-*-clean-medium-r-*-*-8-*-*-*-*-80-* | |
3250 | |
3251 ============================================================================== | |
3252 5. Defining a syntax *:syn-define* *E410* | |
3253 | |
3254 Vim understands three types of syntax items: | |
3255 | |
419 | 3256 1. Keyword |
7 | 3257 It can only contain keyword characters, according to the 'iskeyword' |
3258 option. It cannot contain other syntax items. It will only match with a | |
3259 complete word (there are no keyword characters before or after the match). | |
3260 The keyword "if" would match in "if(a=b)", but not in "ifdef x", because | |
3261 "(" is not a keyword character and "d" is. | |
3262 | |
419 | 3263 2. Match |
7 | 3264 This is a match with a single regexp pattern. |
3265 | |
419 | 3266 3. Region |
7 | 3267 This starts at a match of the "start" regexp pattern and ends with a match |
3268 with the "end" regexp pattern. Any other text can appear in between. A | |
3269 "skip" regexp pattern can be used to avoid matching the "end" pattern. | |
3270 | |
3271 Several syntax ITEMs can be put into one syntax GROUP. For a syntax group | |
3272 you can give highlighting attributes. For example, you could have an item | |
3273 to define a "/* .. */" comment and another one that defines a "// .." comment, | |
3274 and put them both in the "Comment" group. You can then specify that a | |
3275 "Comment" will be in bold font and have a blue color. You are free to make | |
3276 one highlight group for one syntax item, or put all items into one group. | |
3277 This depends on how you want to specify your highlighting attributes. Putting | |
3278 each item in its own group results in having to specify the highlighting | |
3279 for a lot of groups. | |
3280 | |
3281 Note that a syntax group and a highlight group are similar. For a highlight | |
3282 group you will have given highlight attributes. These attributes will be used | |
3283 for the syntax group with the same name. | |
3284 | |
3285 In case more than one item matches at the same position, the one that was | |
3286 defined LAST wins. Thus you can override previously defined syntax items by | |
3287 using an item that matches the same text. But a keyword always goes before a | |
3288 match or region. And a keyword with matching case always goes before a | |
3289 keyword with ignoring case. | |
3290 | |
3291 | |
3292 PRIORITY *:syn-priority* | |
3293 | |
3294 When several syntax items may match, these rules are used: | |
3295 | |
3296 1. When multiple Match or Region items start in the same position, the item | |
3297 defined last has priority. | |
3298 2. A Keyword has priority over Match and Region items. | |
3299 3. An item that starts in an earlier position has priority over items that | |
3300 start in later positions. | |
3301 | |
3302 | |
3303 DEFINING CASE *:syn-case* *E390* | |
3304 | |
419 | 3305 :sy[ntax] case [match | ignore] |
7 | 3306 This defines if the following ":syntax" commands will work with |
3307 matching case, when using "match", or with ignoring case, when using | |
3308 "ignore". Note that any items before this are not affected, and all | |
3309 items until the next ":syntax case" command are affected. | |
3310 | |
3311 | |
419 | 3312 SPELL CHECKING *:syn-spell* |
3313 | |
3314 :sy[ntax] spell [toplevel | notoplevel | default] | |
3315 This defines where spell checking is to be done for text that is not | |
3316 in a syntax item: | |
3317 | |
3318 toplevel: Text is spell checked. | |
3319 notoplevel: Text is not spell checked. | |
3320 default: When there is a @Spell cluster no spell checking. | |
3321 | |
3322 For text in syntax items use the @Spell and @NoSpell clusters | |
3323 |spell-syntax|. When there is no @Spell and no @NoSpell cluster then | |
3324 spell checking is done for "default" and "toplevel". | |
3325 | |
3326 To activate spell checking the 'spell' option must be set. | |
3327 | |
3328 | |
7 | 3329 DEFINING KEYWORDS *:syn-keyword* |
3330 | |
3331 :sy[ntax] keyword {group-name} [{options}] {keyword} .. [{options}] | |
3332 | |
3333 This defines a number of keywords. | |
3334 | |
3335 {group-name} Is a syntax group name such as "Comment". | |
3336 [{options}] See |:syn-arguments| below. | |
3337 {keyword} .. Is a list of keywords which are part of this group. | |
3338 | |
3339 Example: > | |
3340 :syntax keyword Type int long char | |
3341 < | |
3342 The {options} can be given anywhere in the line. They will apply to | |
3343 all keywords given, also for options that come after a keyword. | |
3344 These examples do exactly the same: > | |
3345 :syntax keyword Type contained int long char | |
3346 :syntax keyword Type int long contained char | |
3347 :syntax keyword Type int long char contained | |
838 | 3348 < *E789* |
7 | 3349 When you have a keyword with an optional tail, like Ex commands in |
3350 Vim, you can put the optional characters inside [], to define all the | |
3351 variations at once: > | |
3352 :syntax keyword vimCommand ab[breviate] n[ext] | |
3353 < | |
3354 Don't forget that a keyword can only be recognized if all the | |
3355 characters are included in the 'iskeyword' option. If one character | |
3356 isn't, the keyword will never be recognized. | |
3357 Multi-byte characters can also be used. These do not have to be in | |
3358 'iskeyword'. | |
3359 | |
3360 A keyword always has higher priority than a match or region, the | |
3361 keyword is used if more than one item matches. Keywords do not nest | |
3362 and a keyword can't contain anything else. | |
3363 | |
3364 Note that when you have a keyword that is the same as an option (even | |
3365 one that isn't allowed here), you can not use it. Use a match | |
3366 instead. | |
3367 | |
3368 The maximum length of a keyword is 80 characters. | |
3369 | |
3370 The same keyword can be defined multiple times, when its containment | |
3371 differs. For example, you can define the keyword once not contained | |
3372 and use one highlight group, and once contained, and use a different | |
237 | 3373 highlight group. Example: > |
7 | 3374 :syn keyword vimCommand tag |
3375 :syn keyword vimSetting contained tag | |
3376 < When finding "tag" outside of any syntax item, the "vimCommand" | |
3377 highlight group is used. When finding "tag" in a syntax item that | |
3378 contains "vimSetting", the "vimSetting" group is used. | |
3379 | |
3380 | |
3381 DEFINING MATCHES *:syn-match* | |
3382 | |
3383 :sy[ntax] match {group-name} [{options}] [excludenl] {pattern} [{options}] | |
3384 | |
3385 This defines one match. | |
3386 | |
3387 {group-name} A syntax group name such as "Comment". | |
3388 [{options}] See |:syn-arguments| below. | |
3389 [excludenl] Don't make a pattern with the end-of-line "$" | |
3390 extend a containing match or region. Must be | |
3391 given before the pattern. |:syn-excludenl| | |
3392 {pattern} The search pattern that defines the match. | |
3393 See |:syn-pattern| below. | |
3394 Note that the pattern may match more than one | |
3395 line, which makes the match depend on where | |
3396 Vim starts searching for the pattern. You | |
3397 need to make sure syncing takes care of this. | |
3398 | |
3399 Example (match a character constant): > | |
3400 :syntax match Character /'.'/hs=s+1,he=e-1 | |
3401 < | |
3402 | |
3403 DEFINING REGIONS *:syn-region* *:syn-start* *:syn-skip* *:syn-end* | |
3404 *E398* *E399* | |
3405 :sy[ntax] region {group-name} [{options}] | |
3406 [matchgroup={group-name}] | |
3407 [keepend] | |
3408 [extend] | |
3409 [excludenl] | |
3410 start={start_pattern} .. | |
3411 [skip={skip_pattern}] | |
3412 end={end_pattern} .. | |
3413 [{options}] | |
3414 | |
3415 This defines one region. It may span several lines. | |
3416 | |
3417 {group-name} A syntax group name such as "Comment". | |
3418 [{options}] See |:syn-arguments| below. | |
3419 [matchgroup={group-name}] The syntax group to use for the following | |
3420 start or end pattern matches only. Not used | |
3421 for the text in between the matched start and | |
3422 end patterns. Use NONE to reset to not using | |
3423 a different group for the start or end match. | |
3424 See |:syn-matchgroup|. | |
3425 keepend Don't allow contained matches to go past a | |
3426 match with the end pattern. See | |
3427 |:syn-keepend|. | |
3428 extend Override a "keepend" for an item this region | |
237 | 3429 is contained in. See |:syn-extend|. |
7 | 3430 excludenl Don't make a pattern with the end-of-line "$" |
3431 extend a containing match or item. Only | |
3432 useful for end patterns. Must be given before | |
3433 the patterns it applies to. |:syn-excludenl| | |
3434 start={start_pattern} The search pattern that defines the start of | |
3435 the region. See |:syn-pattern| below. | |
3436 skip={skip_pattern} The search pattern that defines text inside | |
3437 the region where not to look for the end | |
3438 pattern. See |:syn-pattern| below. | |
3439 end={end_pattern} The search pattern that defines the end of | |
3440 the region. See |:syn-pattern| below. | |
3441 | |
3442 Example: > | |
3443 :syntax region String start=+"+ skip=+\\"+ end=+"+ | |
3444 < | |
3445 The start/skip/end patterns and the options can be given in any order. | |
3446 There can be zero or one skip pattern. There must be one or more | |
3447 start and end patterns. This means that you can omit the skip | |
3448 pattern, but you must give at least one start and one end pattern. It | |
3449 is allowed to have white space before and after the equal sign | |
3450 (although it mostly looks better without white space). | |
3451 | |
3452 When more than one start pattern is given, a match with one of these | |
3453 is sufficient. This means there is an OR relation between the start | |
3454 patterns. The last one that matches is used. The same is true for | |
3455 the end patterns. | |
3456 | |
3457 The search for the end pattern starts right after the start pattern. | |
3458 Offsets are not used for this. This implies that the match for the | |
3459 end pattern will never overlap with the start pattern. | |
3460 | |
3461 The skip and end pattern can match across line breaks, but since the | |
3462 search for the pattern can start in any line it often does not do what | |
3463 you want. The skip pattern doesn't avoid a match of an end pattern in | |
3464 the next line. Use single-line patterns to avoid trouble. | |
3465 | |
3466 Note: The decision to start a region is only based on a matching start | |
3467 pattern. There is no check for a matching end pattern. This does NOT | |
3468 work: > | |
3469 :syn region First start="(" end=":" | |
3470 :syn region Second start="(" end=";" | |
3471 < The Second always matches before the First (last defined pattern has | |
3472 higher priority). The Second region then continues until the next | |
3473 ';', no matter if there is a ':' before it. Using a match does work: > | |
3474 :syn match First "(\_.\{-}:" | |
3475 :syn match Second "(\_.\{-};" | |
3476 < This pattern matches any character or line break with "\_." and | |
3477 repeats that with "\{-}" (repeat as few as possible). | |
3478 | |
3479 *:syn-keepend* | |
3480 By default, a contained match can obscure a match for the end pattern. | |
3481 This is useful for nesting. For example, a region that starts with | |
3482 "{" and ends with "}", can contain another region. An encountered "}" | |
3483 will then end the contained region, but not the outer region: | |
3484 { starts outer "{}" region | |
3485 { starts contained "{}" region | |
3486 } ends contained "{}" region | |
3487 } ends outer "{} region | |
3488 If you don't want this, the "keepend" argument will make the matching | |
3489 of an end pattern of the outer region also end any contained item. | |
3490 This makes it impossible to nest the same region, but allows for | |
3491 contained items to highlight parts of the end pattern, without causing | |
3492 that to skip the match with the end pattern. Example: > | |
3493 :syn match vimComment +"[^"]\+$+ | |
3494 :syn region vimCommand start="set" end="$" contains=vimComment keepend | |
3495 < The "keepend" makes the vimCommand always end at the end of the line, | |
3496 even though the contained vimComment includes a match with the <EOL>. | |
3497 | |
3498 When "keepend" is not used, a match with an end pattern is retried | |
3499 after each contained match. When "keepend" is included, the first | |
3500 encountered match with an end pattern is used, truncating any | |
3501 contained matches. | |
3502 *:syn-extend* | |
3503 The "keepend" behavior can be changed by using the "extend" argument. | |
3504 When an item with "extend" is contained in an item that uses | |
3505 "keepend", the "keepend" is ignored and the containing region will be | |
3506 extended. | |
3507 This can be used to have some contained items extend a region while | |
3508 others don't. Example: > | |
3509 | |
3510 :syn region htmlRef start=+<a>+ end=+</a>+ keepend contains=htmlItem,htmlScript | |
3511 :syn match htmlItem +<[^>]*>+ contained | |
3512 :syn region htmlScript start=+<script+ end=+</script[^>]*>+ contained extend | |
3513 | |
3514 < Here the htmlItem item does not make the htmlRef item continue | |
3515 further, it is only used to highlight the <> items. The htmlScript | |
3516 item does extend the htmlRef item. | |
3517 | |
3518 Another example: > | |
3519 :syn region xmlFold start="<a>" end="</a>" fold transparent keepend extend | |
3520 < This defines a region with "keepend", so that its end cannot be | |
3521 changed by contained items, like when the "</a>" is matched to | |
3522 highlight it differently. But when the xmlFold region is nested (it | |
3523 includes itself), the "extend" applies, so that the "</a>" of a nested | |
3524 region only ends that region, and not the one it is contained in. | |
3525 | |
3526 *:syn-excludenl* | |
3527 When a pattern for a match or end pattern of a region includes a '$' | |
3528 to match the end-of-line, it will make a region item that it is | |
3529 contained in continue on the next line. For example, a match with | |
3530 "\\$" (backslash at the end of the line) can make a region continue | |
3531 that would normally stop at the end of the line. This is the default | |
3532 behavior. If this is not wanted, there are two ways to avoid it: | |
3533 1. Use "keepend" for the containing item. This will keep all | |
3534 contained matches from extending the match or region. It can be | |
3535 used when all contained items must not extend the containing item. | |
3536 2. Use "excludenl" in the contained item. This will keep that match | |
3537 from extending the containing match or region. It can be used if | |
3538 only some contained items must not extend the containing item. | |
3539 "excludenl" must be given before the pattern it applies to. | |
3540 | |
3541 *:syn-matchgroup* | |
3542 "matchgroup" can be used to highlight the start and/or end pattern | |
3543 differently than the body of the region. Example: > | |
3544 :syntax region String matchgroup=Quote start=+"+ skip=+\\"+ end=+"+ | |
3545 < This will highlight the quotes with the "Quote" group, and the text in | |
3546 between with the "String" group. | |
3547 The "matchgroup" is used for all start and end patterns that follow, | |
3548 until the next "matchgroup". Use "matchgroup=NONE" to go back to not | |
3549 using a matchgroup. | |
3550 | |
3551 In a start or end pattern that is highlighted with "matchgroup" the | |
3552 contained items of the region are not used. This can be used to avoid | |
3553 that a contained item matches in the start or end pattern match. When | |
3554 using "transparent", this does not apply to a start or end pattern | |
3555 match that is highlighted with "matchgroup". | |
3556 | |
3557 Here is an example, which highlights three levels of parentheses in | |
3558 different colors: > | |
3559 :sy region par1 matchgroup=par1 start=/(/ end=/)/ contains=par2 | |
3560 :sy region par2 matchgroup=par2 start=/(/ end=/)/ contains=par3 contained | |
3561 :sy region par3 matchgroup=par3 start=/(/ end=/)/ contains=par1 contained | |
3562 :hi par1 ctermfg=red guifg=red | |
3563 :hi par2 ctermfg=blue guifg=blue | |
3564 :hi par3 ctermfg=darkgreen guifg=darkgreen | |
2751 | 3565 < |

3619 See |hl-Conceal| for highlighting. |
7 | 3620 |
3621 contained *:syn-contained* | |
3622 | |
3623 When the "contained" argument is given, this item will not be recognized at | |
3624 the top level, but only when it is mentioned in the "contains" field of | |
3625 another match. Example: > | |
3626 :syntax keyword Todo TODO contained | |
3627 :syntax match Comment "//.*" contains=Todo | |
3628 | |
3629 | |
3630 display *:syn-display* | |
3631 | |
3632 If the "display" argument is given, this item will be skipped when the | |
3633 detected highlighting will not be displayed. This will speed up highlighting, | |
3634 by skipping this item when only finding the syntax state for the text that is | |
3635 to be displayed. | |
3636 | |
3637 Generally, you can use "display" for match and region items that meet these | |
3638 conditions: | |
3639 - The item does not continue past the end of a line. Example for C: A region | |
3640 for a "/*" comment can't contain "display", because it continues on the next | |
3641 line. | |
3642 - The item does not contain items that continue past the end of the line or | |
3643 make it continue on the next line. | |
3644 - The item does not change the size of any item it is contained in. Example | |
3645 for C: A match with "\\$" in a preprocessor match can't have "display", | |
3646 because it may make that preprocessor match shorter. | |
3647 - The item does not allow other items to match that didn't match otherwise, | |
3648 and that item may extend the match too far. Example for C: A match for a | |
3649 "//" comment can't use "display", because a "/*" inside that comment would | |
3650 match then and start a comment which extends past the end of the line. | |
3651 | |
3652 Examples, for the C language, where "display" can be used: | |
3653 - match with a number | |
3654 - match with a label | |
3655 | |
3656 | |
3657 transparent *:syn-transparent* | |
3658 | |
3659 If the "transparent" argument is given, this item will not be highlighted | |
3660 itself, but will take the highlighting of the item it is contained in. This | |
3661 is useful for syntax items that don't need any highlighting but are used | |
3662 only to skip over a part of the text. | |
3663 | |
3664 The "contains=" argument is also inherited from the item it is contained in, | |
3665 unless a "contains" argument is given for the transparent item itself. To | |
3666 avoid that unwanted items are contained, use "contains=NONE". Example, which | |
3667 highlights words in strings, but makes an exception for "vim": > | |
3668 :syn match myString /'[^']*'/ contains=myWord,myVim | |
3669 :syn match myWord /\<[a-z]*\>/ contained | |
3670 :syn match myVim /\<vim\>/ transparent contained contains=NONE | |
3671 :hi link myString String | |
3672 :hi link myWord Comment | |
3673 Since the "myVim" match comes after "myWord" it is the preferred match (last | |
3674 match in the same position overrules an earlier one). The "transparent" | |
3675 argument makes the "myVim" match use the same highlighting as "myString". But | |
3676 it does not contain anything. If the "contains=NONE" argument would be left | |
3677 out, then "myVim" would use the contains argument from myString and allow | |
3678 "myWord" to be contained, which will be highlighted as a Constant. This | |
3679 happens because a contained match doesn't match inside itself in the same | |
3680 position, thus the "myVim" match doesn't overrule the "myWord" match here. | |
3681 | |
3682 When you look at the colored text, it is like looking at layers of contained | |
3683 items. The contained item is on top of the item it is contained in, thus you | |
3684 see the contained item. When a contained item is transparent, you can look | |
3685 through, thus you see the item it is contained in. In a picture: | |

3693 .................... contained item (transparent) | |
3694 ============================= first item | |
3695 | |
3696 The 'x', 'y' and '=' represent a highlighted syntax item. The '.' represent a | |
3697 transparent group. | |
3698 | |
3699 What you see is: | |
3700 | |
3701 =======xxxx=======yyy======== | |
3702 | |
3703 Thus you look through the transparent "....". | |
3704 | |
3705 | |
3706 oneline *:syn-oneline* | |
3707 | |
3708 The "oneline" argument indicates that the region does not cross a line | |
3709 boundary. It must match completely in the current line. However, when the | |
3710 region has a contained item that does cross a line boundary, it continues on | |
3711 the next line anyway. A contained item can be used to recognize a line | |
3712 continuation pattern. But the "end" pattern must still match in the first | |
3713 line, otherwise the region doesn't even start. | |
3714 | |
3715 When the start pattern includes a "\n" to match an end-of-line, the end | |
3716 pattern must be found in the same line as where the start pattern ends. The | |
3717 end pattern may also include an end-of-line. Thus the "oneline" argument | |
3718 means that the end of the start pattern and the start of the end pattern must | |
3719 be within one line. This can't be changed by a skip pattern that matches a | |
3720 line break. | |
3721 | |
3722 | |
3723 fold *:syn-fold* | |
3724 | |
1624 | 3725 The "fold" argument makes the fold level increase by one for this item. |
7 | 3726 Example: > |
3727 :syn region myFold start="{" end="}" transparent fold | |
3728 :syn sync fromstart | |
3729 :set foldmethod=syntax | |
3730 This will make each {} block form one fold. | |
3731 | |
3732 The fold will start on the line where the item starts, and end where the item | |
3733 ends. If the start and end are within the same line, there is no fold. | |
3734 The 'foldnestmax' option limits the nesting of syntax folds. | |
3735 {not available when Vim was compiled without |+folding| feature} | |
3736 | |
3737 | |
3738 *:syn-contains* *E405* *E406* *E407* *E408* *E409* | |
3739 contains={groupname},.. | |
3740 | |
3741 The "contains" argument is followed by a list of syntax group names. These | |
3742 groups will be allowed to begin inside the item (they may extend past the | |
3743 containing group's end). This allows for recursive nesting of matches and | |
3744 regions. If there is no "contains" argument, no groups will be contained in | |
3745 this item. The group names do not need to be defined before they can be used | |
3746 here. | |
3747 | |
3748 contains=ALL | |
3749 If the only item in the contains list is "ALL", then all | |
3750 groups will be accepted inside the item. | |
3751 | |
3752 contains=ALLBUT,{group-name},.. | |
3753 If the first item in the contains list is "ALLBUT", then all | |
3754 groups will be accepted inside the item, except the ones that | |
3755 are listed. Example: > | |
3756 :syntax region Block start="{" end="}" ... contains=ALLBUT,Function | |
3757 | |
3758 contains=TOP | |
3759 If the first item in the contains list is "TOP", then all | |
3760 groups will be accepted that don't have the "contained" | |
3761 argument. | |
3762 contains=TOP,{group-name},.. | |
3763 Like "TOP", but excluding the groups that are listed. | |
3764 | |
3765 contains=CONTAINED | |
3766 If the first item in the contains list is "CONTAINED", then | |
3767 all groups will be accepted that have the "contained" | |
3768 argument. | |
3769 contains=CONTAINED,{group-name},.. | |
3770 Like "CONTAINED", but excluding the groups that are | |
3771 listed. | |
3772 | |
3773 | |
3774 The {group-name} in the "contains" list can be a pattern. All group names | |
3775 that match the pattern will be included (or excluded, if "ALLBUT" is used). | |
3776 The pattern cannot contain white space or a ','. Example: > | |
3777 ... contains=Comment.*,Keyw[0-3] | |
3778 The matching will be done at moment the syntax command is executed. Groups | |
3779 that are defined later will not be matched. Also, if the current syntax | |
3780 command defines a new group, it is not matched. Be careful: When putting | |
3781 syntax commands in a file you can't rely on groups NOT being defined, because | |
3782 the file may have been sourced before, and ":syn clear" doesn't remove the | |
3783 group names. | |
3784 | |
3785 The contained groups will also match in the start and end patterns of a | |
3786 region. If this is not wanted, the "matchgroup" argument can be used | |
3787 |:syn-matchgroup|. The "ms=" and "me=" offsets can be used to change the | |
3788 region where contained items do match. Note that this may also limit the | |
3789 area that is highlighted | |
3790 | |
3791 | |
3792 containedin={groupname}... *:syn-containedin* | |
3793 | |
3794 The "containedin" argument is followed by a list of syntax group names. The | |
3795 item will be allowed to begin inside these groups. This works as if the | |
3796 containing item has a "contains=" argument that includes this item. | |
3797 | |
3798 The {groupname}... can be used just like for "contains", as explained above. | |
3799 | |
3800 This is useful when adding a syntax item afterwards. An item can be told to | |
3801 be included inside an already existing item, without changing the definition | |
3802 of that item. For example, to highlight a word in a C comment after loading | |
3803 the C syntax: > | |
3804 :syn keyword myword HELP containedin=cComment contained | |
3805 Note that "contained" is also used, to avoid that the item matches at the top | |
3806 level. | |
3807 | |
3808 Matches for "containedin" are added to the other places where the item can | |
3809 appear. A "contains" argument may also be added as usual. Don't forget that | |
3810 keywords never contain another item, thus adding them to "containedin" won't | |
3811 work. | |
3812 | |
3813 | |
3814 nextgroup={groupname},.. *:syn-nextgroup* | |
3815 | |
3816 The "nextgroup" argument is followed by a list of syntax group names, | |
3817 separated by commas (just like with "contains", so you can also use patterns). | |
3818 | |
3819 If the "nextgroup" argument is given, the mentioned syntax groups will be | |
3820 tried for a match, after the match or region ends. If none of the groups have | |
3821 a match, highlighting continues normally. If there is a match, this group | |
3822 will be used, even when it is not mentioned in the "contains" field of the | |
3823 current group. This is like giving the mentioned group priority over all | |
3824 other groups. Example: > | |
3825 :syntax match ccFoobar "Foo.\{-}Bar" contains=ccFoo | |
3826 :syntax match ccFoo "Foo" contained nextgroup=ccFiller | |
3827 :syntax region ccFiller start="." matchgroup=ccBar end="Bar" contained | |
3828 | |
3829 This will highlight "Foo" and "Bar" differently, and only when there is a | |
3830 "Bar" after "Foo". In the text line below, "f" shows where ccFoo is used for | |
3831 highlighting, and "bbb" where ccBar is used. > | |
3832 | |
3833 Foo asdfasd Bar asdf Foo asdf Bar asdf | |
3834 fff bbb fff bbb | |
3835 | |
3836 Note the use of ".\{-}" to skip as little as possible until the next Bar. | |
3837 when ".*" would be used, the "asdf" in between "Bar" and "Foo" would be | |
3838 highlighted according to the "ccFoobar" group, because the ccFooBar match | |
3839 would include the first "Foo" and the last "Bar" in the line (see |pattern|). | |
3840 | |
3841 | |
3842 skipwhite *:syn-skipwhite* | |
3843 skipnl *:syn-skipnl* | |
3844 skipempty *:syn-skipempty* | |
3845 | |
3846 These arguments are only used in combination with "nextgroup". They can be | |
3847 used to allow the next group to match after skipping some text: | |
1275 | 3848 skipwhite skip over space and tab characters |
7 | 3849 skipnl skip over the end of a line |
3850 skipempty skip over empty lines (implies a "skipnl") | |
3851 | |
3852 When "skipwhite" is present, the white space is only skipped if there is no | |
3853 next group that matches the white space. | |
3854 | |
3855 When "skipnl" is present, the match with nextgroup may be found in the next | |
3856 line. This only happens when the current item ends at the end of the current | |
3857 line! When "skipnl" is not present, the nextgroup will only be found after | |
3858 the current item in the same line. | |
3859 | |
3860 When skipping text while looking for a next group, the matches for other | |
3861 groups are ignored. Only when no next group matches, other items are tried | |
3862 for a match again. This means that matching a next group and skipping white | |
3863 space and <EOL>s has a higher priority than other items. | |
3864 | |
3865 Example: > | |
3866 :syn match ifstart "\<if.*" nextgroup=ifline skipwhite skipempty | |
3867 :syn match ifline "[^ \t].*" nextgroup=ifline skipwhite skipempty contained | |
3868 :syn match ifline "endif" contained | |
3869 Note that the "[^ \t].*" match matches all non-white text. Thus it would also | |
3870 match "endif". Therefore the "endif" match is put last, so that it takes | |
3871 precedence. | |
3872 Note that this example doesn't work for nested "if"s. You need to add | |
3873 "contains" arguments to make that work (omitted for simplicity of the | |
3874 example). | |

7 | 3886 ============================================================================== |
3887 7. Syntax patterns *:syn-pattern* *E401* *E402* | |
3888 | |
3889 In the syntax commands, a pattern must be surrounded by two identical | |
3890 characters. This is like it works for the ":s" command. The most common to | |
3891 use is the double quote. But if the pattern contains a double quote, you can | |
3892 use another character that is not used in the pattern. Examples: > | |
3893 :syntax region Comment start="/\*" end="\*/" | |
3894 :syntax region String start=+"+ end=+"+ skip=+\\"+ | |
3895 | |
3896 See |pattern| for the explanation of what a pattern is. Syntax patterns are | |
1624 | 3897 always interpreted like the 'magic' option is set, no matter what the actual |
7 | 3898 value of 'magic' is. And the patterns are interpreted like the 'l' flag is |
3899 not included in 'cpoptions'. This was done to make syntax files portable and | |
3900 independent of 'compatible' and 'magic' settings. | |
3901 | |
3902 Try to avoid patterns that can match an empty string, such as "[a-z]*". | |
3903 This slows down the highlighting a lot, because it matches everywhere. | |
3904 | |
3905 *:syn-pattern-offset* | |
3906 The pattern can be followed by a character offset. This can be used to | |
3907 change the highlighted part, and to change the text area included in the | |
3908 match or region (which only matters when trying to match other items). Both | |
3909 are relative to the matched pattern. The character offset for a skip | |
3910 pattern can be used to tell where to continue looking for an end pattern. | |
3911 | |
3912 The offset takes the form of "{what}={offset}" | |
3913 The {what} can be one of seven strings: | |
3914 | |
3915 ms Match Start offset for the start of the matched text | |
3916 me Match End offset for the end of the matched text | |
3917 hs Highlight Start offset for where the highlighting starts | |
3918 he Highlight End offset for where the highlighting ends | |
3919 rs Region Start offset for where the body of a region starts | |
3920 re Region End offset for where the body of a region ends | |
3921 lc Leading Context offset past "leading context" of pattern | |
3922 | |
3923 The {offset} can be: | |
3924 | |
3925 s start of the matched pattern | |
3926 s+{nr} start of the matched pattern plus {nr} chars to the right | |
3927 s-{nr} start of the matched pattern plus {nr} chars to the left | |
3928 e end of the matched pattern | |
3929 e+{nr} end of the matched pattern plus {nr} chars to the right | |
3930 e-{nr} end of the matched pattern plus {nr} chars to the left | |
4229 | 3931 {nr} (for "lc" only): start matching {nr} chars right of the start |
7 | 3932 |
3933 Examples: "ms=s+1", "hs=e-2", "lc=3". | |
3934 | |
3935 Although all offsets are accepted after any pattern, they are not always | |
3936 meaningful. This table shows which offsets are actually used: | |
3937 | |
3938 ms me hs he rs re lc ~ | |
3939 match item yes yes yes yes - - yes | |
3940 region item start yes - yes - yes - yes | |
3941 region item skip - yes - - - - yes | |
3942 region item end - yes - yes - yes yes | |
3943 | |
3944 Offsets can be concatenated, with a ',' in between. Example: > | |
3945 :syn match String /"[^"]*"/hs=s+1,he=e-1 | |
3946 < | |
3947 some "string" text | |
3948 ^^^^^^ highlighted | |
3949 | |
3950 Notes: | |
3951 - There must be no white space between the pattern and the character | |
3952 offset(s). | |
3953 - The highlighted area will never be outside of the matched text. | |
3954 - A negative offset for an end pattern may not always work, because the end | |
3955 pattern may be detected when the highlighting should already have stopped. | |

3958 Vim 7.2 release. |
7 | 3959 - The start of a match cannot be in a line other than where the pattern |
3960 matched. This doesn't work: "a\nb"ms=e. You can make the highlighting | |
3961 start in another line, this does work: "a\nb"hs=e. | |
3962 | |
3963 Example (match a comment but don't highlight the /* and */): > | |
3964 :syntax region Comment start="/\*"hs=e+1 end="\*/"he=s-1 | |
3965 < | |
3966 /* this is a comment */ | |
3967 ^^^^^^^^^^^^^^^^^^^ highlighted | |
3968 | |
3969 A more complicated Example: > | |
3970 :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 | |
3971 < | |
3972 abcfoostringbarabc | |
3973 mmmmmmmmmmm match | |
625 | 3974 sssrrreee highlight start/region/end ("Foo", "Exa" and "Bar") |
7 | 3975 |
3976 Leading context *:syn-lc* *:syn-leading* *:syn-context* | |
3977 | |
3978 Note: This is an obsolete feature, only included for backwards compatibility | |
3979 with previous Vim versions. It's now recommended to use the |/\@<=| construct | |
3980 in the pattern. | |
3981 | |
3982 The "lc" offset specifies leading context -- a part of the pattern that must | |
3983 be present, but is not considered part of the match. An offset of "lc=n" will | |
3984 cause Vim to step back n columns before attempting the pattern match, allowing | |
3985 characters which have already been matched in previous patterns to also be | |
3986 used as leading context for this match. This can be used, for instance, to | |
3987 specify that an "escaping" character must not precede the match: > | |
3988 | |
3989 :syn match ZNoBackslash "[^\\]z"ms=s+1 | |
3990 :syn match WNoBackslash "[^\\]w"lc=1 | |
3991 :syn match Underline "_\+" | |
3992 < | |
3993 ___zzzz ___wwww | |
3994 ^^^ ^^^ matches Underline | |
3995 ^ ^ matches ZNoBackslash | |
3996 ^^^^ matches WNoBackslash | |
3997 | |
3998 The "ms" offset is automatically set to the same value as the "lc" offset, | |
3999 unless you set "ms" explicitly. | |
4000 | |
4001 | |
4002 Multi-line patterns *:syn-multi-line* | |
4003 | |
4004 The patterns can include "\n" to match an end-of-line. Mostly this works as | |
4005 expected, but there are a few exceptions. | |
4006 | |
4007 When using a start pattern with an offset, the start of the match is not | |
4008 allowed to start in a following line. The highlighting can start in a | |

4009 following line though. Using the "\zs" item also requires that the start of |

|
4010 the match doesn't move to another line. |
7 | 4011 |
4012 The skip pattern can include the "\n", but the search for an end pattern will | |
4013 continue in the first character of the next line, also when that character is | |
4014 matched by the skip pattern. This is because redrawing may start in any line | |
4015 halfway a region and there is no check if the skip pattern started in a | |
4016 previous line. For example, if the skip pattern is "a\nb" and an end pattern | |
4017 is "b", the end pattern does match in the second line of this: > | |
4018 x x a | |
4019 b x x | |
4020 Generally this means that the skip pattern should not match any characters | |
4021 after the "\n". | |
4022 | |
4023 | |
4024 External matches *:syn-ext-match* | |
4025 | |
4026 These extra regular expression items are available in region patterns: | |
4027 | |
4780 | 4028 */\z(* */\z(\)* *E50* *E52* *E879* |
4073 | 4029 \z(\) Marks the sub-expression as "external", meaning that it can be |
4030 accessed from another pattern match. Currently only usable in | |
4031 defining a syntax region start pattern. | |
7 | 4032 |
4033 */\z1* */\z2* */\z3* */\z4* */\z5* | |
4034 \z1 ... \z9 */\z6* */\z7* */\z8* */\z9* *E66* *E67* | |
4035 Matches the same string that was matched by the corresponding | |
4036 sub-expression in a previous start pattern match. | |
4037 | |
4038 Sometimes the start and end patterns of a region need to share a common | |
4039 sub-expression. A common example is the "here" document in Perl and many Unix | |
4040 shells. This effect can be achieved with the "\z" special regular expression | |
4041 items, which marks a sub-expression as "external", in the sense that it can be | |
4042 referenced from outside the pattern in which it is defined. The here-document | |
4043 example, for instance, can be done like this: > | |
4044 :syn region hereDoc start="<<\z(\I\i*\)" end="^\z1$" | |
4045 | |
4046 As can be seen here, the \z actually does double duty. In the start pattern, | |
4047 it marks the "\(\I\i*\)" sub-expression as external; in the end pattern, it | |
4048 changes the \1 back-reference into an external reference referring to the | |
4049 first external sub-expression in the start pattern. External references can | |
4050 also be used in skip patterns: > | |
4051 :syn region foo start="start \(\I\i*\)" skip="not end \z1" end="end \z1" | |
4052 | |
4053 Note that normal and external sub-expressions are completely orthogonal and | |
4054 indexed separately; for instance, if the pattern "\z(..\)\(..\)" is applied | |
4055 to the string "aabb", then \1 will refer to "bb" and \z1 will refer to "aa". | |
4056 Note also that external sub-expressions cannot be accessed as back-references | |
4057 within the same pattern like normal sub-expressions. If you want to use one | |
4058 sub-expression as both a normal and an external sub-expression, you can nest | |
4059 the two, as in "\(\z(...\)\)". | |
4060 | |
4061 Note that only matches within a single line can be used. Multi-line matches | |
4062 cannot be referred to. | |

4070 | |
4071 This command allows you to cluster a list of syntax groups together under a | |
4072 single name. | |
4073 | |
4074 contains={group-name}.. | |
4075 The cluster is set to the specified list of groups. | |
4076 add={group-name}.. | |
4077 The specified groups are added to the cluster. | |
4078 remove={group-name}.. | |
4079 The specified groups are removed from the cluster. | |
4080 | |
1624 | 4081 A cluster so defined may be referred to in a contains=.., containedin=.., |
4082 nextgroup=.., add=.. or remove=.. list with a "@" prefix. You can also use | |
4083 this notation to implicitly declare a cluster before specifying its contents. | |
7 | 4084 |
4085 Example: > | |
4086 :syntax match Thing "# [^#]\+ #" contains=@ThingMembers | |
4087 :syntax cluster ThingMembers contains=ThingMember1,ThingMember2 | |
4088 | |
4089 As the previous example suggests, modifications to a cluster are effectively | |
4090 retroactive; the membership of the cluster is checked at the last minute, so | |
4091 to speak: > | |
4092 :syntax keyword A aaa | |
4093 :syntax keyword B bbb | |
4094 :syntax cluster AandB contains=A | |
4095 :syntax match Stuff "( aaa bbb )" contains=@AandB | |
4096 :syntax cluster AandB add=B " now both keywords are matched in Stuff | |
4097 | |
4098 This also has implications for nested clusters: > | |
4099 :syntax keyword A aaa | |
4100 :syntax keyword B bbb | |
4101 :syntax cluster SmallGroup contains=B | |
4102 :syntax cluster BigGroup contains=A,@SmallGroup | |
4103 :syntax match Stuff "( aaa bbb )" contains=@BigGroup | |
4104 :syntax cluster BigGroup remove=B " no effect, since B isn't in BigGroup | |
4105 :syntax cluster SmallGroup remove=B " now bbb isn't matched within Stuff | |
2751 | 4106 < |
4107 *E848* | |
4108 The maximum number of clusters is 9767. | |
7 | 4109 |
4110 ============================================================================== | |
4111 9. Including syntax files *:syn-include* *E397* | |
4112 | |
4113 It is often useful for one language's syntax file to include a syntax file for | |
4114 a related language. Depending on the exact relationship, this can be done in | |
4115 two different ways: | |
4116 | |
4117 - If top-level syntax items in the included syntax file are to be | |
4118 allowed at the top level in the including syntax, you can simply use | |
4119 the |:runtime| command: > | |
4120 | |
4121 " In cpp.vim: | |
4122 :runtime! syntax/c.vim | |
4123 :unlet b:current_syntax | |
4124 | |
4125 < - If top-level syntax items in the included syntax file are to be | |
4126 contained within a region in the including syntax, you can use the | |
4127 ":syntax include" command: | |
4128 | |
4129 :sy[ntax] include [@{grouplist-name}] {file-name} | |
4130 | |
4131 All syntax items declared in the included file will have the | |
4132 "contained" flag added. In addition, if a group list is specified, | |
4133 all top-level syntax items in the included file will be added to | |
4134 that list. > | |
4135 | |
4136 " In perl.vim: | |
4137 :syntax include @Pod <sfile>:p:h/pod.vim | |
4138 :syntax region perlPOD start="^=head" end="^=cut" contains=@Pod | |
4139 < | |
4140 When {file-name} is an absolute path (starts with "/", "c:", "$VAR" | |
4141 or "<sfile>") that file is sourced. When it is a relative path | |
4142 (e.g., "syntax/pod.vim") the file is searched for in 'runtimepath'. | |
4143 All matching files are loaded. Using a relative path is | |
4144 recommended, because it allows a user to replace the included file | |
4145 with his own version, without replacing the file that does the ":syn | |
4146 include". | |
4147 | |
2751 | 4148 *E847* |
4149 The maximum number of includes is 999. | |
4150 | |
7 | 4151 ============================================================================== |
4152 10. Synchronizing *:syn-sync* *E403* *E404* | |
4153 | |
4154 Vim wants to be able to start redrawing in any position in the document. To | |
4155 make this possible it needs to know the syntax state at the position where | |
4156 redrawing starts. | |
4157 | |
4158 :sy[ntax] sync [ccomment [group-name] | minlines={N} | ...] | |
4159 | |
4160 There are four ways to synchronize: | |
4161 1. Always parse from the start of the file. | |
4162 |:syn-sync-first| | |
4163 2. Based on C-style comments. Vim understands how C-comments work and can | |
4164 figure out if the current line starts inside or outside a comment. | |
4165 |:syn-sync-second| | |
4166 3. Jumping back a certain number of lines and start parsing there. | |
4167 |:syn-sync-third| | |
4168 4. Searching backwards in the text for a pattern to sync on. | |
4169 |:syn-sync-fourth| | |
4170 | |
4171 *:syn-sync-maxlines* *:syn-sync-minlines* | |
4172 For the last three methods, the line range where the parsing can start is | |
4173 limited by "minlines" and "maxlines". | |
4174 | |
4175 If the "minlines={N}" argument is given, the parsing always starts at least | |
4176 that many lines backwards. This can be used if the parsing may take a few | |
4177 lines before it's correct, or when it's not possible to use syncing. | |
4178 | |
4179 If the "maxlines={N}" argument is given, the number of lines that are searched | |
4180 for a comment or syncing pattern is restricted to N lines backwards (after | |
4181 adding "minlines"). This is useful if you have few things to sync on and a | |
4182 slow machine. Example: > | |
4183 :syntax sync ccomment maxlines=500 | |
4184 < | |
4185 *:syn-sync-linebreaks* | |
4186 When using a pattern that matches multiple lines, a change in one line may | |
4187 cause a pattern to no longer match in a previous line. This means has to | |
4188 start above where the change was made. How many lines can be specified with | |
4189 the "linebreaks" argument. For example, when a pattern may include one line | |
4190 break use this: > | |
4191 :syntax sync linebreaks=1 | |
4192 The result is that redrawing always starts at least one line before where a | |
4193 change was made. The default value for "linebreaks" is zero. Usually the | |
4194 value for "minlines" is bigger than "linebreaks". | |
4195 | |
4196 | |
4197 First syncing method: *:syn-sync-first* | |
4198 > | |
4199 :syntax sync fromstart | |
4200 | |
4201 The file will be parsed from the start. This makes syntax highlighting | |
4202 accurate, but can be slow for long files. Vim caches previously parsed text, | |
4203 so that it's only slow when parsing the text for the first time. However, | |
3224 | 4204 when making changes some part of the text needs to be parsed again (worst |
7 | 4205 case: to the end of the file). |
4206 | |
4207 Using "fromstart" is equivalent to using "minlines" with a very large number. | |
4208 | |
4209 | |
4210 Second syncing method: *:syn-sync-second* *:syn-sync-ccomment* | |
4211 | |
4212 For the second method, only the "ccomment" argument needs to be given. | |
4213 Example: > | |
4214 :syntax sync ccomment | |
4215 | |
4216 When Vim finds that the line where displaying starts is inside a C-style | |
4217 comment, the last region syntax item with the group-name "Comment" will be | |
4218 used. This requires that there is a region with the group-name "Comment"! | |
4219 An alternate group name can be specified, for example: > | |
4220 :syntax sync ccomment javaComment | |
4221 This means that the last item specified with "syn region javaComment" will be | |
4222 used for the detected C comment region. This only works properly if that | |
4223 region does have a start pattern "\/*" and an end pattern "*\/". | |
4224 | |
4225 The "maxlines" argument can be used to restrict the search to a number of | |
4226 lines. The "minlines" argument can be used to at least start a number of | |
4227 lines back (e.g., for when there is some construct that only takes a few | |
4228 lines, but it hard to sync on). | |
4229 | |
4230 Note: Syncing on a C comment doesn't work properly when strings are used | |
4231 that cross a line and contain a "*/". Since letting strings cross a line | |
4232 is a bad programming habit (many compilers give a warning message), and the | |
4233 chance of a "*/" appearing inside a comment is very small, this restriction | |
4234 is hardly ever noticed. | |
4235 | |
4236 | |
4237 Third syncing method: *:syn-sync-third* | |
4238 | |
4239 For the third method, only the "minlines={N}" argument needs to be given. | |
4240 Vim will subtract {N} from the line number and start parsing there. This | |
4241 means {N} extra lines need to be parsed, which makes this method a bit slower. | |
4242 Example: > | |
4243 :syntax sync minlines=50 | |
4244 | |
4245 "lines" is equivalent to "minlines" (used by older versions). | |
4246 | |
4247 | |
4248 Fourth syncing method: *:syn-sync-fourth* | |
4249 | |
4250 The idea is to synchronize on the end of a few specific regions, called a | |
4251 sync pattern. Only regions can cross lines, so when we find the end of some | |
4252 region, we might be able to know in which syntax item we are. The search | |
4253 starts in the line just above the one where redrawing starts. From there | |
4254 the search continues backwards in the file. | |
4255 | |
4256 This works just like the non-syncing syntax items. You can use contained | |
4257 matches, nextgroup, etc. But there are a few differences: | |
4258 - Keywords cannot be used. | |
4259 - The syntax items with the "sync" keyword form a completely separated group | |
4260 of syntax items. You can't mix syncing groups and non-syncing groups. | |
4261 - The matching works backwards in the buffer (line by line), instead of | |
4262 forwards. | |
4263 - A line continuation pattern can be given. It is used to decide which group | |
4264 of lines need to be searched like they were one line. This means that the | |
4265 search for a match with the specified items starts in the first of the | |
4266 consecutive that contain the continuation pattern. | |
4267 - When using "nextgroup" or "contains", this only works within one line (or | |
4268 group of continued lines). | |
4269 - When using a region, it must start and end in the same line (or group of | |
4270 continued lines). Otherwise the end is assumed to be at the end of the | |
4271 line (or group of continued lines). | |
4272 - When a match with a sync pattern is found, the rest of the line (or group of | |
4273 continued lines) is searched for another match. The last match is used. | |
4274 This is used when a line can contain both the start end the end of a region | |
4275 (e.g., in a C-comment like /* this */, the last "*/" is used). | |
4276 | |
4277 There are two ways how a match with a sync pattern can be used: | |
4278 1. Parsing for highlighting starts where redrawing starts (and where the | |
4279 search for the sync pattern started). The syntax group that is expected | |
4280 to be valid there must be specified. This works well when the regions | |
4281 that cross lines cannot contain other regions. | |
4282 2. Parsing for highlighting continues just after the match. The syntax group | |
4283 that is expected to be present just after the match must be specified. | |
4284 This can be used when the previous method doesn't work well. It's much | |
4285 slower, because more text needs to be parsed. | |
4286 Both types of sync patterns can be used at the same time. | |
4287 | |
4288 Besides the sync patterns, other matches and regions can be specified, to | |
4289 avoid finding unwanted matches. | |
4290 | |
4291 [The reason that the sync patterns are given separately, is that mostly the | |
4292 search for the sync point can be much simpler than figuring out the | |
4293 highlighting. The reduced number of patterns means it will go (much) | |
4294 faster.] | |
4295 | |
4296 *syn-sync-grouphere* *E393* *E394* | |
4297 :syntax sync match {sync-group-name} grouphere {group-name} "pattern" .. | |
4298 | |
4299 Define a match that is used for syncing. {group-name} is the | |
4300 name of a syntax group that follows just after the match. Parsing | |
4301 of the text for highlighting starts just after the match. A region | |
4302 must exist for this {group-name}. The first one defined will be used. | |
4303 "NONE" can be used for when there is no syntax group after the match. | |
4304 | |
4305 *syn-sync-groupthere* | |
4306 :syntax sync match {sync-group-name} groupthere {group-name} "pattern" .. | |
4307 | |
4308 Like "grouphere", but {group-name} is the name of a syntax group that | |
4309 is to be used at the start of the line where searching for the sync | |
4310 point started. The text between the match and the start of the sync | |
4311 pattern searching is assumed not to change the syntax highlighting. | |
4312 For example, in C you could search backwards for "/*" and "*/". If | |
4313 "/*" is found first, you know that you are inside a comment, so the | |
4314 "groupthere" is "cComment". If "*/" is found first, you know that you | |
4315 are not in a comment, so the "groupthere" is "NONE". (in practice | |
4316 it's a bit more complicated, because the "/*" and "*/" could appear | |
4317 inside a string. That's left as an exercise to the reader...). | |
4318 | |
4319 :syntax sync match .. | |
4320 :syntax sync region .. | |
4321 | |
4322 Without a "groupthere" argument. Define a region or match that is | |
4323 skipped while searching for a sync point. | |
4324 | |
856 | 4325 *syn-sync-linecont* |
7 | 4326 :syntax sync linecont {pattern} |
4327 | |
4328 When {pattern} matches in a line, it is considered to continue in | |
4329 the next line. This means that the search for a sync point will | |
4330 consider the lines to be concatenated. | |
4331 | |
4332 If the "maxlines={N}" argument is given too, the number of lines that are | |
4333 searched for a match is restricted to N. This is useful if you have very | |
4334 few things to sync on and a slow machine. Example: > | |
4335 :syntax sync maxlines=100 | |
4336 | |
4337 You can clear all sync settings with: > | |
4338 :syntax sync clear | |
4339 | |
4340 You can clear specific sync patterns with: > | |
4341 :syntax sync clear {sync-group-name} .. | |
4342 | |
4343 ============================================================================== | |
4344 11. Listing syntax items *:syntax* *:sy* *:syn* *:syn-list* | |
4345 | |
534 | 4346 This command lists all the syntax items: > |
7 | 4347 |
4348 :sy[ntax] [list] | |
4349 | |
4350 To show the syntax items for one syntax group: > | |
4351 | |
4352 :sy[ntax] list {group-name} | |
4353 | |
2581 | 4354 To list the syntax groups in one cluster: *E392* > |
7 | 4355 |
4356 :sy[ntax] list @{cluster-name} | |
4357 | |
4358 See above for other arguments for the ":syntax" command. | |
4359 | |
4360 Note that the ":syntax" command can be abbreviated to ":sy", although ":syn" | |
4361 is mostly used, because it looks better. | |
4362 | |
4363 ============================================================================== | |
4364 12. Highlight command *:highlight* *:hi* *E28* *E411* *E415* | |
4365 | |
4366 There are three types of highlight groups: | |
4367 - The ones used for specific languages. For these the name starts with the | |
4368 name of the language. Many of these don't have any attributes, but are | |
4369 linked to a group of the second type. | |
4370 - The ones used for all syntax languages. | |
4371 - The ones used for the 'highlight' option. | |
4372 *hitest.vim* | |
4373 You can see all the groups currently active with this command: > | |
4374 :so $VIMRUNTIME/syntax/hitest.vim | |
4375 This will open a new window containing all highlight group names, displayed | |
4376 in their own color. | |
4377 | |
4378 *:colo* *:colorscheme* *E185* | |
2152 | 4379 :colo[rscheme] Output the name of the currently active color scheme. |
4380 This is basically the same as > | |
4381 :echo g:colors_name | |
4382 < In case g:colors_name has not been defined :colo will | |
4383 output "default". When compiled without the |+eval| | |
4384 feature it will output "unknown". | |
4385 | |
7 | 4386 :colo[rscheme] {name} Load color scheme {name}. This searches 'runtimepath' |

4399 :hi[ghlight] List all the current highlight groups that have | |
4400 attributes set. | |
4401 | |
4402 :hi[ghlight] {group-name} | |
4403 List one highlight group. | |
4404 | |
4405 :hi[ghlight] clear Reset all highlighting to the defaults. Removes all | |
4406 highlighting for groups added by the user! | |
4407 Uses the current value of 'background' to decide which | |
4408 default colors to use. | |
4409 | |
4410 :hi[ghlight] clear {group-name} | |
4411 :hi[ghlight] {group-name} NONE | |
4412 Disable the highlighting for one highlight group. It | |
4413 is _not_ set back to the default colors. | |
4414 | |
4415 :hi[ghlight] [default] {group-name} {key}={arg} .. | |
4416 Add a highlight group, or change the highlighting for | |
4417 an existing group. | |
4418 See |highlight-args| for the {key}={arg} arguments. | |
4419 See |:highlight-default| for the optional [default] | |
4420 argument. | |
4421 | |
4422 Normally a highlight group is added once when starting up. This sets the | |
4423 default values for the highlighting. After that, you can use additional | |
4424 highlight commands to change the arguments that you want to set to non-default | |
4425 values. The value "NONE" can be used to switch the value off or go back to | |
4426 the default value. | |
4427 | |
4428 A simple way to change colors is with the |:colorscheme| command. This loads | |
4429 a file with ":highlight" commands such as this: > | |
4430 | |
4431 :hi Comment gui=bold | |
4432 | |
4433 Note that all settings that are not included remain the same, only the | |
4434 specified field is used, and settings are merged with previous ones. So, the | |
4435 result is like this single command has been used: > | |
4436 :hi Comment term=bold ctermfg=Cyan guifg=#80a0ff gui=bold | |
4437 < | |
856 | 4438 *:highlight-verbose* |
448 | 4439 When listing a highlight group and 'verbose' is non-zero, the listing will |
4440 also tell where it was last set. Example: > | |
4441 :verbose hi Comment | |
4442 < Comment xxx term=bold ctermfg=4 guifg=Blue ~ | |
856 | 4443 Last set from /home/mool/vim/vim7/runtime/syntax/syncolor.vim ~ |
448 | 4444 |
484 | 4445 When ":hi clear" is used then the script where this command is used will be |
4446 mentioned for the default values. See |:verbose-cmd| for more information. | |
448 | 4447 |
7 | 4448 *highlight-args* *E416* *E417* *E423* |
4449 There are three types of terminals for highlighting: | |
4450 term a normal terminal (vt100, xterm) | |
4451 cterm a color terminal (MS-DOS console, color-xterm, these have the "Co" | |
4452 termcap entry) | |
4453 gui the GUI | |
4454 | |
4455 For each type the highlighting can be given. This makes it possible to use | |
4456 the same syntax file on all terminals, and use the optimal highlighting. | |
4457 | |
4458 1. highlight arguments for normal terminals | |
4459 | |
301 | 4460 *bold* *underline* *undercurl* |
4461 *inverse* *italic* *standout* | |
7 | 4462 term={attr-list} *attr-list* *highlight-term* *E418* |
4463 attr-list is a comma separated list (without spaces) of the | |
4464 following items (in any order): | |
4465 bold | |
4466 underline | |
217 | 4467 undercurl not always available |
7 | 4468 reverse |
4469 inverse same as reverse | |
4470 italic | |
4471 standout | |
4472 NONE no attributes used (used to reset it) | |
4473 | |
4474 Note that "bold" can be used here and by using a bold font. They | |
4475 have the same effect. | |
217 | 4476 "undercurl" is a curly underline. When "undercurl" is not possible |
4477 then "underline" is used. In general "undercurl" is only available in | |
819 | 4478 the GUI. The color is set with |highlight-guisp|. |
7 | 4479 |
4480 start={term-list} *highlight-start* *E422* | |
4481 stop={term-list} *term-list* *highlight-stop* | |
4482 These lists of terminal codes can be used to get | |
4483 non-standard attributes on a terminal. | |
4484 | |
4485 The escape sequence specified with the "start" argument | |
4486 is written before the characters in the highlighted | |
4487 area. It can be anything that you want to send to the | |
4488 terminal to highlight this area. The escape sequence | |
4489 specified with the "stop" argument is written after the | |
4490 highlighted area. This should undo the "start" argument. | |
4491 Otherwise the screen will look messed up. | |
4492 | |
4493 The {term-list} can have two forms: | |
4494 | |
4495 1. A string with escape sequences. | |
4496 This is any string of characters, except that it can't start with | |
4497 "t_" and blanks are not allowed. The <> notation is recognized | |
4498 here, so you can use things like "<Esc>" and "<Space>". Example: | |
4499 start=<Esc>[27h;<Esc>[<Space>r; | |
4500 | |
4501 2. A list of terminal codes. | |
4502 Each terminal code has the form "t_xx", where "xx" is the name of | |
4503 the termcap entry. The codes have to be separated with commas. | |
4504 White space is not allowed. Example: | |
4505 start=t_C1,t_BL | |
4506 The terminal codes must exist for this to work. | |
4507 | |
4508 | |
4509 2. highlight arguments for color terminals | |
4510 | |
4511 cterm={attr-list} *highlight-cterm* | |
4512 See above for the description of {attr-list} |attr-list|. | |
4513 The "cterm" argument is likely to be different from "term", when | |
4514 colors are used. For example, in a normal terminal comments could | |
4515 be underlined, in a color terminal they can be made Blue. | |
4516 Note: Many terminals (e.g., DOS console) can't mix these attributes | |
4517 with coloring. Use only one of "cterm=" OR "ctermfg=" OR "ctermbg=". | |
4518 | |
4519 ctermfg={color-nr} *highlight-ctermfg* *E421* | |
4520 ctermbg={color-nr} *highlight-ctermbg* | |
4521 The {color-nr} argument is a color number. Its range is zero to | |
4522 (not including) the number given by the termcap entry "Co". | |
4523 The actual color with this number depends on the type of terminal | |
4524 and its settings. Sometimes the color also depends on the settings of | |
4525 "cterm". For example, on some systems "cterm=bold ctermfg=3" gives | |
4526 another color, on others you just get color 3. | |
4527 | |
4528 For an xterm this depends on your resources, and is a bit | |
4529 unpredictable. See your xterm documentation for the defaults. The | |
4530 colors for a color-xterm can be changed from the .Xdefaults file. | |
4531 Unfortunately this means that it's not possible to get the same colors | |
4532 for each user. See |xterm-color| for info about color xterms. | |
4533 | |
4534 The MSDOS standard colors are fixed (in a console window), so these | |
4535 have been used for the names. But the meaning of color names in X11 | |
4536 are fixed, so these color settings have been used, to make the | |
4537 highlighting settings portable (complicated, isn't it?). The | |
4538 following names are recognized, with the color number used: | |
4539 | |
4540 *cterm-colors* | |
4541 NR-16 NR-8 COLOR NAME ~ | |
4542 0 0 Black | |
4543 1 4 DarkBlue | |
4544 2 2 DarkGreen | |
4545 3 6 DarkCyan | |
4546 4 1 DarkRed | |
4547 5 5 DarkMagenta | |
4548 6 3 Brown, DarkYellow | |
4549 7 7 LightGray, LightGrey, Gray, Grey | |
4550 8 0* DarkGray, DarkGrey | |
4551 9 4* Blue, LightBlue | |
4552 10 2* Green, LightGreen | |
4553 11 6* Cyan, LightCyan | |
4554 12 1* Red, LightRed | |
4555 13 5* Magenta, LightMagenta | |
4556 14 3* Yellow, LightYellow | |
4557 15 7* White | |
4558 | |
4559 The number under "NR-16" is used for 16-color terminals ('t_Co' | |
4560 greater than or equal to 16). The number under "NR-8" is used for | |
4561 8-color terminals ('t_Co' less than 16). The '*' indicates that the | |
4562 bold attribute is set for ctermfg. In many 8-color terminals (e.g., | |
4563 "linux"), this causes the bright colors to appear. This doesn't work | |
4564 for background colors! Without the '*' the bold attribute is removed. | |
4565 If you want to set the bold attribute in a different way, put a | |
4566 "cterm=" argument AFTER the "ctermfg=" or "ctermbg=" argument. Or use | |
4567 a number instead of a color name. | |
4568 | |
4569 The case of the color names is ignored. | |
4570 Note that for 16 color ansi style terminals (including xterms), the | |
237 | 4571 numbers in the NR-8 column is used. Here '*' means 'add 8' so that Blue |
7 | 4572 is 12, DarkGray is 8 etc. |
4573 | |
4574 Note that for some color terminals these names may result in the wrong | |
4575 colors! | |
4576 | |
4577 *:hi-normal-cterm* | |
4578 When setting the "ctermfg" or "ctermbg" colors for the Normal group, | |
4579 these will become the colors used for the non-highlighted text. | |
4580 Example: > | |
4581 :highlight Normal ctermfg=grey ctermbg=darkblue | |
4582 < When setting the "ctermbg" color for the Normal group, the | |
4583 'background' option will be adjusted automatically. This causes the | |
4584 highlight groups that depend on 'background' to change! This means | |
4585 you should set the colors for Normal first, before setting other | |
4586 colors. | |
4587 When a colorscheme is being used, changing 'background' causes it to | |
4588 be reloaded, which may reset all colors (including Normal). First | |

4589 delete the "g:colors_name" variable when you don't want this. |
7 | 4590 |
4591 When you have set "ctermfg" or "ctermbg" for the Normal group, Vim | |
4592 needs to reset the color when exiting. This is done with the "op" | |
4593 termcap entry |t_op|. If this doesn't work correctly, try setting the | |
4594 't_op' option in your .vimrc. | |
4595 *E419* *E420* | |
4596 When Vim knows the normal foreground and background colors, "fg" and | |
4597 "bg" can be used as color names. This only works after setting the | |
4598 colors for the Normal group and for the MS-DOS console. Example, for | |
4599 reverse video: > | |
4600 :highlight Visual ctermfg=bg ctermbg=fg | |
4601 < Note that the colors are used that are valid at the moment this | |
4602 command are given. If the Normal group colors are changed later, the | |
4603 "fg" and "bg" colors will not be adjusted. | |
4604 | |
4605 | |
4606 3. highlight arguments for the GUI | |
4607 | |
4608 gui={attr-list} *highlight-gui* | |
4609 These give the attributes to use in the GUI mode. | |
4610 See |attr-list| for a description. | |
4611 Note that "bold" can be used here and by using a bold font. They | |
4612 have the same effect. | |
4613 Note that the attributes are ignored for the "Normal" group. | |
4614 | |
4615 font={font-name} *highlight-font* | |
4616 font-name is the name of a font, as it is used on the system Vim | |
4617 runs on. For X11 this is a complicated name, for example: > | |
4618 font=-misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1 | |
4619 < | |
4620 The font-name "NONE" can be used to revert to the default font. | |
4621 When setting the font for the "Normal" group, this becomes the default | |
4622 font (until the 'guifont' option is changed; the last one set is | |
4623 used). | |
4624 The following only works with Motif and Athena, not with other GUIs: | |
4625 When setting the font for the "Menu" group, the menus will be changed. | |
4626 When setting the font for the "Tooltip" group, the tooltips will be | |
4627 changed. | |
4628 All fonts used, except for Menu and Tooltip, should be of the same | |
4629 character size as the default font! Otherwise redrawing problems will | |
4630 occur. | |
4631 | |
4632 guifg={color-name} *highlight-guifg* | |
4633 guibg={color-name} *highlight-guibg* | |
217 | 4634 guisp={color-name} *highlight-guisp* |
4635 These give the foreground (guifg), background (guibg) and special | |
642 | 4636 (guisp) color to use in the GUI. "guisp" is used for undercurl. |
4637 There are a few special names: | |
7 | 4638 NONE no color (transparent) |
4639 bg use normal background color | |
4640 background use normal background color | |
4641 fg use normal foreground color | |
4642 foreground use normal foreground color | |
4643 To use a color name with an embedded space or other special character, | |
4644 put it in single quotes. The single quote cannot be used then. | |
4645 Example: > | |
4646 :hi comment guifg='salmon pink' | |
4647 < | |
4648 *gui-colors* | |
4649 Suggested color names (these are available on most systems): | |
4650 Red LightRed DarkRed | |
4651 Green LightGreen DarkGreen SeaGreen | |
4652 Blue LightBlue DarkBlue SlateBlue | |
4653 Cyan LightCyan DarkCyan | |
4654 Magenta LightMagenta DarkMagenta | |
4655 Yellow LightYellow Brown DarkYellow | |
4656 Gray LightGray DarkGray | |
4657 Black White | |
4658 Orange Purple Violet | |
4659 | |
4660 In the Win32 GUI version, additional system colors are available. See | |
4661 |win32-colors|. | |
4662 | |
4663 You can also specify a color by its Red, Green and Blue values. | |
4664 The format is "#rrggbb", where | |
4665 "rr" is the Red value | |
217 | 4666 "gg" is the Green value |
7 | 4667 "bb" is the Blue value |
4668 All values are hexadecimal, range from "00" to "ff". Examples: > | |
4669 :highlight Comment guifg=#11f0c3 guibg=#ff00ff | |
4670 < | |
4671 *highlight-groups* *highlight-default* | |
4672 These are the default highlighting groups. These groups are used by the | |
4673 'highlight' option default. Note that the highlighting depends on the value | |
4674 of 'background'. You can see the current settings with the ":highlight" | |
4675 command. | |

1624 | 4796 For the GUI you can use the following groups to set the colors for the menu, |
7 | 4797 scrollbars and tooltips. They don't have defaults. This doesn't work for the |
4798 Win32 GUI. Only three highlight arguments have any effect here: font, guibg, | |

4805 | |
4806 NOTE: For Motif and Athena the font argument actually | |
4807 specifies a fontset at all times, no matter if 'guifontset' is | |
4808 empty, and as such it is tied to the current |:language| when | |

4824 | |
4825 ============================================================================== | |
4826 13. Linking groups *:hi-link* *:highlight-link* *E412* *E413* | |
4827 | |
4828 When you want to use the same highlighting for several syntax groups, you | |
4829 can do this more easily by linking the groups into one common highlight | |
4830 group, and give the color attributes only for that group. | |
4831 | |
4832 To set a link: | |
4833 | |
4834 :hi[ghlight][!] [default] link {from-group} {to-group} | |
4835 | |
4836 To remove a link: | |
4837 | |
4838 :hi[ghlight][!] [default] link {from-group} NONE | |
4839 | |
4840 Notes: *E414* | |
4841 - If the {from-group} and/or {to-group} doesn't exist, it is created. You | |
4842 don't get an error message for a non-existing group. | |
4843 - As soon as you use a ":highlight" command for a linked group, the link is | |
4844 removed. | |
4845 - If there are already highlight settings for the {from-group}, the link is | |
4846 not made, unless the '!' is given. For a ":highlight link" command in a | |
4847 sourced file, you don't get an error message. This can be used to skip | |
4848 links for groups that already have settings. | |
4849 | |
4850 *:hi-default* *:highlight-default* | |
4851 The [default] argument is used for setting the default highlighting for a | |
4852 group. If highlighting has already been specified for the group the command | |
4853 will be ignored. Also when there is an existing link. | |
4854 | |
4855 Using [default] is especially useful to overrule the highlighting of a | |
4856 specific syntax file. For example, the C syntax file contains: > | |
4857 :highlight default link cComment Comment | |
4858 If you like Question highlighting for C comments, put this in your vimrc file: > | |
4859 :highlight link cComment Question | |
4860 Without the "default" in the C syntax file, the highlighting would be | |
4861 overruled when the syntax file is loaded. | |
4862 | |
4863 ============================================================================== | |
4864 14. Cleaning up *:syn-clear* *E391* | |
4865 | |
4866 If you want to clear the syntax stuff for the current buffer, you can use this | |
4867 command: > | |
4868 :syntax clear | |
4869 | |
4870 This command should be used when you want to switch off syntax highlighting, | |
4871 or when you want to switch to using another syntax. It's normally not needed | |
4872 in a syntax file itself, because syntax is cleared by the autocommands that | |
4873 load the syntax file. | |
4874 The command also deletes the "b:current_syntax" variable, since no syntax is | |
4875 loaded after this command. | |
4876 | |
4877 If you want to disable syntax highlighting for all buffers, you need to remove | |
4878 the autocommands that load the syntax files: > | |
4879 :syntax off | |
4880 | |
4881 What this command actually does, is executing the command > | |
4882 :source $VIMRUNTIME/syntax/nosyntax.vim | |
4883 See the "nosyntax.vim" file for details. Note that for this to work | |
4884 $VIMRUNTIME must be valid. See |$VIMRUNTIME|. | |
4885 | |
4886 To clean up specific syntax groups for the current buffer: > | |
4887 :syntax clear {group-name} .. | |
4888 This removes all patterns and keywords for {group-name}. | |
4889 | |
4890 To clean up specific syntax group lists for the current buffer: > | |
4891 :syntax clear @{grouplist-name} .. | |
4892 This sets {grouplist-name}'s contents to an empty list. | |
4893 | |
4894 *:syntax-reset* *:syn-reset* | |
4895 If you have changed the colors and messed them up, use this command to get the | |
4896 defaults back: > | |
4897 | |
4898 :syntax reset | |
4899 | |
4900 This doesn't change the colors for the 'highlight' option. | |
4901 | |
4902 Note that the syntax colors that you set in your vimrc file will also be reset | |
4903 back to their Vim default. | |
4904 Note that if you are using a color scheme, the colors defined by the color | |
4905 scheme for syntax highlighting will be lost. | |
4906 | |
4907 What this actually does is: > | |
4908 | |
4909 let g:syntax_cmd = "reset" | |
4910 runtime! syntax/syncolor.vim | |
4911 | |
4912 Note that this uses the 'runtimepath' option. | |
4913 | |
4914 *syncolor* | |
4915 If you want to use different colors for syntax highlighting, you can add a Vim | |
4916 script file to set these colors. Put this file in a directory in | |
4917 'runtimepath' which comes after $VIMRUNTIME, so that your settings overrule | |
4918 the default colors. This way these colors will be used after the ":syntax | |
4919 reset" command. | |
4920 | |
4921 For Unix you can use the file ~/.vim/after/syntax/syncolor.vim. Example: > | |
4922 | |
4923 if &background == "light" | |
4924 highlight comment ctermfg=darkgreen guifg=darkgreen | |
4925 else | |
4926 highlight comment ctermfg=green guifg=green | |
4927 endif | |
4928 | |
24 | 4929 *E679* |
4930 Do make sure this syncolor.vim script does not use a "syntax on", set the | |
4931 'background' option or uses a "colorscheme" command, because it results in an | |
4932 endless loop. | |
4933 | |
7 | 4934 Note that when a color scheme is used, there might be some confusion whether |
4935 your defined colors are to be used or the colors from the scheme. This | |
4936 depends on the color scheme file. See |:colorscheme|. | |
4937 | |
4938 *syntax_cmd* | |
4939 The "syntax_cmd" variable is set to one of these values when the | |
4940 syntax/syncolor.vim files are loaded: | |
4941 "on" ":syntax on" command. Highlight colors are overruled but | |
4942 links are kept | |
4943 "enable" ":syntax enable" command. Only define colors for groups that | |
4944 don't have highlighting yet. Use ":syntax default". | |
4945 "reset" ":syntax reset" command or loading a color scheme. Define all | |
4946 the colors. | |
4947 "skip" Don't define colors. Used to skip the default settings when a | |
4948 syncolor.vim file earlier in 'runtimepath' has already set | |
4949 them. | |
4950 | |
4951 ============================================================================== | |
4952 15. Highlighting tags *tag-highlight* | |
4953 | |
4954 If you want to highlight all the tags in your file, you can use the following | |
4955 mappings. | |
4956 | |
4957 <F11> -- Generate tags.vim file, and highlight tags. | |
4958 <F12> -- Just highlight tags based on existing tags.vim file. | |
4959 > | |
4960 :map <F11> :sp tags<CR>:%s/^\([^ :]*:\)\=\([^ ]*\).*/syntax keyword Tag \2/<CR>:wq! tags.vim<CR>/^<CR><F12> | |
4961 :map <F12> :so tags.vim<CR> | |
4962 | |
4963 WARNING: The longer the tags file, the slower this will be, and the more | |
4964 memory Vim will consume. | |
4965 | |
4966 Only highlighting typedefs, unions and structs can be done too. For this you | |
4967 must use Exuberant ctags (found at http://ctags.sf.net). | |
4968 | |
4969 Put these lines in your Makefile: | |
4970 | |
4971 # Make a highlight file for types. Requires Exuberant ctags and awk | |
4972 types: types.vim | |
4973 types.vim: *.[ch] | |
1125 | 4974 ctags --c-kinds=gstu -o- *.[ch] |\ |
7 | 4975 awk 'BEGIN{printf("syntax keyword Type\t")}\ |
4976 {printf("%s ", $$1)}END{print ""}' > $@ | |
4977 | |
4978 And put these lines in your .vimrc: > | |
4979 | |
4980 " load the types.vim highlighting file, if it exists | |
4981 autocmd BufRead,BufNewFile *.[ch] let fname = expand('<afile>:p:h') . '/types.vim' | |
4982 autocmd BufRead,BufNewFile *.[ch] if filereadable(fname) | |
4983 autocmd BufRead,BufNewFile *.[ch] exe 'so ' . fname | |
4984 autocmd BufRead,BufNewFile *.[ch] endif | |

2581 | 5016 17. Color xterms *xterm-color* *color-xterm* |
7 | 5017 |
5018 Most color xterms have only eight colors. If you don't get colors with the | |
5019 default setup, it should work with these lines in your .vimrc: > | |
5020 :if &term =~ "xterm" | |
5021 : if has("terminfo") | |
5022 : set t_Co=8 | |
5023 : set t_Sf=<Esc>[3%p1%dm | |
5024 : set t_Sb=<Esc>[4%p1%dm | |
5025 : else | |
5026 : set t_Co=8 | |
5027 : set t_Sf=<Esc>[3%dm | |
5028 : set t_Sb=<Esc>[4%dm | |
5029 : endif | |
5030 :endif | |
5031 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
5032 | |
5033 You might want to change the first "if" to match the name of your terminal, | |
5034 e.g. "dtterm" instead of "xterm". | |
5035 | |
5036 Note: Do these settings BEFORE doing ":syntax on". Otherwise the colors may | |
5037 be wrong. | |
5038 *xiterm* *rxvt* | |
5039 The above settings have been mentioned to work for xiterm and rxvt too. | |
5040 But for using 16 colors in an rxvt these should work with terminfo: > | |
5041 :set t_AB=<Esc>[%?%p1%{8}%<%t25;%p1%{40}%+%e5;%p1%{32}%+%;%dm | |
5042 :set t_AF=<Esc>[%?%p1%{8}%<%t22;%p1%{30}%+%e1;%p1%{22}%+%;%dm | |
5043 < | |
5044 *colortest.vim* | |
5045 To test your color setup, a file has been included in the Vim distribution. | |
671 | 5046 To use it, execute this command: > |
5047 :runtime syntax/colortest.vim | |
7 | 5048 |
237 | 5049 Some versions of xterm (and other terminals, like the Linux console) can |
7 | 5050 output lighter foreground colors, even though the number of colors is defined |
5051 at 8. Therefore Vim sets the "cterm=bold" attribute for light foreground | |
5052 colors, when 't_Co' is 8. | |
5053 | |
5054 *xfree-xterm* | |
5055 To get 16 colors or more, get the newest xterm version (which should be | |
237 | 5056 included with XFree86 3.3 and later). You can also find the latest version |
7 | 5057 at: > |
5058 http://invisible-island.net/xterm/xterm.html | |
5059 Here is a good way to configure it. This uses 88 colors and enables the | |
5060 termcap-query feature, which allows Vim to ask the xterm how many colors it | |
5061 supports. > | |
5062 ./configure --disable-bold-color --enable-88-color --enable-tcap-query | |
5063 If you only get 8 colors, check the xterm compilation settings. | |
5064 (Also see |UTF8-xterm| for using this xterm with UTF-8 character encoding). | |
5065 | |
5066 This xterm should work with these lines in your .vimrc (for 16 colors): > | |
5067 :if has("terminfo") | |
5068 : set t_Co=16 | |
5069 : set t_AB=<Esc>[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{92}%+%;%dm | |
5070 : set t_AF=<Esc>[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{82}%+%;%dm | |
5071 :else | |
5072 : set t_Co=16 | |
5073 : set t_Sf=<Esc>[3%dm | |
5074 : set t_Sb=<Esc>[4%dm | |
5075 :endif | |
5076 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
5077 | |
5078 Without |+terminfo|, Vim will recognize these settings, and automatically | |
5079 translate cterm colors of 8 and above to "<Esc>[9%dm" and "<Esc>[10%dm". | |
5080 Colors above 16 are also translated automatically. | |
5081 | |
5082 For 256 colors this has been reported to work: > | |
5083 | |
5084 :set t_AB=<Esc>[48;5;%dm | |
5085 :set t_AF=<Esc>[38;5;%dm | |
5086 | |
5087 Or just set the TERM environment variable to "xterm-color" or "xterm-16color" | |
5088 and try if that works. | |
5089 | |
5090 You probably want to use these X resources (in your ~/.Xdefaults file): | |
5091 XTerm*color0: #000000 | |
5092 XTerm*color1: #c00000 | |
5093 XTerm*color2: #008000 | |
5094 XTerm*color3: #808000 | |
5095 XTerm*color4: #0000c0 | |
5096 XTerm*color5: #c000c0 | |
5097 XTerm*color6: #008080 | |
5098 XTerm*color7: #c0c0c0 | |
5099 XTerm*color8: #808080 | |
5100 XTerm*color9: #ff6060 | |
5101 XTerm*color10: #00ff00 | |
5102 XTerm*color11: #ffff00 | |
5103 XTerm*color12: #8080ff | |
5104 XTerm*color13: #ff40ff | |
5105 XTerm*color14: #00ffff | |
5106 XTerm*color15: #ffffff | |
5107 Xterm*cursorColor: Black | |
5108 | |
5109 [Note: The cursorColor is required to work around a bug, which changes the | |
5110 cursor color to the color of the last drawn text. This has been fixed by a | |
1125 | 5111 newer version of xterm, but not everybody is using it yet.] |
7 | 5112 |
5113 To get these right away, reload the .Xdefaults file to the X Option database | |
5114 Manager (you only need to do this when you just changed the .Xdefaults file): > | |
5115 xrdb -merge ~/.Xdefaults | |
5116 < | |
5117 *xterm-blink* *xterm-blinking-cursor* | |
5118 To make the cursor blink in an xterm, see tools/blink.c. Or use Thomas | |
5119 Dickey's xterm above patchlevel 107 (see above for where to get it), with | |
5120 these resources: | |
5121 XTerm*cursorBlink: on | |
5122 XTerm*cursorOnTime: 400 | |
5123 XTerm*cursorOffTime: 250 | |
5124 XTerm*cursorColor: White | |
5125 | |
5126 *hpterm-color* | |
1125 | 5127 These settings work (more or less) for an hpterm, which only supports 8 |
7 | 5128 foreground colors: > |
5129 :if has("terminfo") | |
5130 : set t_Co=8 | |
5131 : set t_Sf=<Esc>[&v%p1%dS | |
5132 : set t_Sb=<Esc>[&v7S | |
5133 :else | |
5134 : set t_Co=8 | |
5135 : set t_Sf=<Esc>[&v%dS | |
5136 : set t_Sb=<Esc>[&v7S | |
5137 :endif | |
5138 < [<Esc> is a real escape, type CTRL-V <Esc>] | |
5139 | |
5140 *Eterm* *enlightened-terminal* | |
5141 These settings have been reported to work for the Enlightened terminal | |
5142 emulator, or Eterm. They might work for all xterm-like terminals that use the | |
5143 bold attribute to get bright colors. Add an ":if" like above when needed. > | |
5144 :set t_Co=16 | |
5145 :set t_AF=^[[%?%p1%{8}%<%t3%p1%d%e%p1%{22}%+%d;1%;m | |
5146 :set t_AB=^[[%?%p1%{8}%<%t4%p1%d%e%p1%{32}%+%d;1%;m | |
5147 < | |
5148 *TTpro-telnet* | |
5149 These settings should work for TTpro telnet. Tera Term Pro is a freeware / | |
5150 open-source program for MS-Windows. > | |
5151 set t_Co=16 | |
5152 set t_AB=^[[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{32}%+5;%;%dm | |
5153 set t_AF=^[[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{22}%+1;%;%dm | |
5154 Also make sure TTpro's Setup / Window / Full Color is enabled, and make sure | |
5155 that Setup / Font / Enable Bold is NOT enabled. | |
