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

43Syntax highlighting is not available when the |+syntax| feature has been
44disabled at compile time.
45
46==============================================================================
471. Quick start *:syn-qstart*
48
49 *:syn-enable* *:syntax-enable*
50This command switches on syntax highlighting: >
51
52 :syntax enable
53
54What this command actually does is to execute the command >
55 :source $VIMRUNTIME/syntax/syntax.vim
56
57If the VIM environment variable is not set, Vim will try to find
58the path in another way (see |$VIMRUNTIME|). Usually this works just
59fine. If it doesn't, try setting the VIM environment variable to the
60directory where the Vim stuff is located. For example, if your syntax files
61are in the "/usr/vim/vim50/syntax" directory, set $VIMRUNTIME to
62"/usr/vim/vim50". You must do this in the shell, before starting Vim.
63
64 *:syn-on* *:syntax-on*
65The ":syntax enable" command will keep your current color settings. This
66allows using ":highlight" commands to set your preferred colors before or
67after using this command. If you want Vim to overrule your settings with the
68defaults, use: >
69 :syntax on
70<
71 *:hi-normal* *:highlight-normal*
72If you are running in the GUI, you can get white text on a black background
73with: >
74 :highlight Normal guibg=Black guifg=White
75For a color terminal see |:hi-normal-cterm|.
76For setting up your own colors syntax highlighting see |syncolor|.
77
78NOTE: The syntax files on MS-DOS and Windows have lines that end in <CR><NL>.
79The files for Unix end in <NL>. This means you should use the right type of
80file for your system. Although on MS-DOS and Windows the right format is
81automatically selected if the 'fileformats' option is not empty.
82
83NOTE: When using reverse video ("gvim -fg white -bg black"), the default value
84of 'background' will not be set until the GUI window is opened, which is after
Bram Moolenaar910f66f2006-04-05 20:41:53 +000085reading the |gvimrc|. This will cause the wrong default highlighting to be
Bram Moolenaar071d4272004-06-13 20:20:40 +000086used. To set the default value of 'background' before switching on
Bram Moolenaar910f66f2006-04-05 20:41:53 +000087highlighting, include the ":gui" command in the |gvimrc|: >
Bram Moolenaar071d4272004-06-13 20:20:40 +000088
89 :gui " open window and set default for 'background'
90 :syntax on " start highlighting, use 'background' to set colors
91
Bram Moolenaar910f66f2006-04-05 20:41:53 +000092NOTE: Using ":gui" in the |gvimrc| means that "gvim -f" won't start in the
Bram Moolenaar071d4272004-06-13 20:20:40 +000093foreground! Use ":gui -f" then.
94
Bram Moolenaar09092152010-08-08 16:38:42 +020095 *g:syntax_on*
96You can toggle the syntax on/off with this command: >
97 :if exists("g:syntax_on") | syntax off | else | syntax enable | endif
Bram Moolenaar071d4272004-06-13 20:20:40 +000098
99To put this into a mapping, you can use: >
Bram Moolenaar09092152010-08-08 16:38:42 +0200100 :map <F7> :if exists("g:syntax_on") <Bar>
Bram Moolenaar071d4272004-06-13 20:20:40 +0000101 \ syntax off <Bar>
102 \ else <Bar>
103 \ syntax enable <Bar>
104 \ endif <CR>
105[using the |<>| notation, type this literally]
106
Bram Moolenaar8c8de832008-06-24 22:58:06 +0000107Details:
Bram Moolenaar071d4272004-06-13 20:20:40 +0000108The ":syntax" commands are implemented by sourcing a file. To see exactly how
109this works, look in the file:
110 command file ~
111 :syntax enable $VIMRUNTIME/syntax/syntax.vim
112 :syntax on $VIMRUNTIME/syntax/syntax.vim
113 :syntax manual $VIMRUNTIME/syntax/manual.vim
114 :syntax off $VIMRUNTIME/syntax/nosyntax.vim
115Also see |syntax-loading|.
116
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100117NOTE: If displaying long lines is slow and switching off syntax highlighting
118makes it fast, consider setting the 'synmaxcol' option to a lower value.
119
Bram Moolenaar071d4272004-06-13 20:20:40 +0000120==============================================================================
1212. Syntax files *:syn-files*
122
123The syntax and highlighting commands for one language are normally stored in
124a syntax file. The name convention is: "{name}.vim". Where {name} is the
125name of the language, or an abbreviation (to fit the name in 8.3 characters,
126a requirement in case the file is used on a DOS filesystem).
127Examples:
128 c.vim perl.vim java.vim html.vim
129 cpp.vim sh.vim csh.vim
130
131The syntax file can contain any Ex commands, just like a vimrc file. But
132the idea is that only commands for a specific language are included. When a
133language is a superset of another language, it may include the other one,
134for example, the cpp.vim file could include the c.vim file: >
135 :so $VIMRUNTIME/syntax/c.vim
136
137The .vim files are normally loaded with an autocommand. For example: >
138 :au Syntax c runtime! syntax/c.vim
139 :au Syntax cpp runtime! syntax/cpp.vim
140These commands are normally in the file $VIMRUNTIME/syntax/synload.vim.
141
142
143MAKING YOUR OWN SYNTAX FILES *mysyntaxfile*
144
145When you create your own syntax files, and you want to have Vim use these
146automatically with ":syntax enable", do this:
147
1481. Create your user runtime directory. You would normally use the first item
149 of the 'runtimepath' option. Example for Unix: >
150 mkdir ~/.vim
151
1522. Create a directory in there called "syntax". For Unix: >
153 mkdir ~/.vim/syntax
154
1553. Write the Vim syntax file. Or download one from the internet. Then write
156 it in your syntax directory. For example, for the "mine" syntax: >
157 :w ~/.vim/syntax/mine.vim
158
159Now you can start using your syntax file manually: >
160 :set syntax=mine
161You don't have to exit Vim to use this.
162
163If you also want Vim to detect the type of file, see |new-filetype|.
164
165If you are setting up a system with many users and you don't want each user
166to add the same syntax file, you can use another directory from 'runtimepath'.
167
168
169ADDING TO AN EXISTING SYNTAX FILE *mysyntaxfile-add*
170
171If you are mostly satisfied with an existing syntax file, but would like to
172add a few items or change the highlighting, follow these steps:
173
1741. Create your user directory from 'runtimepath', see above.
175
1762. Create a directory in there called "after/syntax". For Unix: >
177 mkdir ~/.vim/after
178 mkdir ~/.vim/after/syntax
179
1803. Write a Vim script that contains the commands you want to use. For
181 example, to change the colors for the C syntax: >
182 highlight cComment ctermfg=Green guifg=Green
183
1844. Write that file in the "after/syntax" directory. Use the name of the
185 syntax, with ".vim" added. For our C syntax: >
186 :w ~/.vim/after/syntax/c.vim
187
188That's it. The next time you edit a C file the Comment color will be
189different. You don't even have to restart Vim.
190
Bram Moolenaar5313dcb2005-02-22 08:56:13 +0000191If you have multiple files, you can use the filetype as the directory name.
192All the "*.vim" files in this directory will be used, for example:
193 ~/.vim/after/syntax/c/one.vim
194 ~/.vim/after/syntax/c/two.vim
195
Bram Moolenaar071d4272004-06-13 20:20:40 +0000196
197REPLACING AN EXISTING SYNTAX FILE *mysyntaxfile-replace*
198
199If you don't like a distributed syntax file, or you have downloaded a new
200version, follow the same steps as for |mysyntaxfile| above. Just make sure
201that you write the syntax file in a directory that is early in 'runtimepath'.
202Vim will only load the first syntax file found.
203
204
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100205NAMING CONVENTIONS *group-name* *{group-name}* *E669* *W18*
206
207A syntax group name is to be used for syntax items that match the same kind of
208thing. These are then linked to a highlight group that specifies the color.
209A syntax group name doesn't specify any color or attributes itself.
210
Bram Moolenaar071d4272004-06-13 20:20:40 +0000211The name for a highlight or syntax group must consist of ASCII letters, digits
212and the underscore. As a regexp: "[a-zA-Z0-9_]*"
213
214To be able to allow each user to pick his favorite set of colors, there must
215be preferred names for highlight groups that are common for many languages.
216These are the suggested group names (if syntax highlighting works properly
217you can see the actual color, except for "Ignore"):
218
219 *Comment any comment
220
221 *Constant any constant
222 String a string constant: "this is a string"
223 Character a character constant: 'c', '\n'
224 Number a number constant: 234, 0xff
225 Boolean a boolean constant: TRUE, false
226 Float a floating point constant: 2.3e10
227
228 *Identifier any variable name
229 Function function name (also: methods for classes)
230
231 *Statement any statement
232 Conditional if, then, else, endif, switch, etc.
233 Repeat for, do, while, etc.
234 Label case, default, etc.
235 Operator "sizeof", "+", "*", etc.
236 Keyword any other keyword
237 Exception try, catch, throw
238
239 *PreProc generic Preprocessor
240 Include preprocessor #include
241 Define preprocessor #define
242 Macro same as Define
243 PreCondit preprocessor #if, #else, #endif, etc.
244
245 *Type int, long, char, etc.
246 StorageClass static, register, volatile, etc.
247 Structure struct, union, enum, etc.
248 Typedef A typedef
249
250 *Special any special symbol
251 SpecialChar special character in a constant
252 Tag you can use CTRL-] on this
253 Delimiter character that needs attention
254 SpecialComment special things inside a comment
255 Debug debugging statements
256
257 *Underlined text that stands out, HTML links
258
Bram Moolenaar4f99eae2010-07-24 15:56:43 +0200259 *Ignore left blank, hidden |hl-Ignore|
Bram Moolenaar071d4272004-06-13 20:20:40 +0000260
261 *Error any erroneous construct
262
263 *Todo anything that needs extra attention; mostly the
264 keywords TODO FIXME and XXX
265
266The names marked with * are the preferred groups; the others are minor groups.
267For the preferred groups, the "syntax.vim" file contains default highlighting.
268The minor groups are linked to the preferred groups, so they get the same
269highlighting. You can override these defaults by using ":highlight" commands
270after sourcing the "syntax.vim" file.
271
272Note that highlight group names are not case sensitive. "String" and "string"
273can be used for the same group.
274
275The following names are reserved and cannot be used as a group name:
276 NONE ALL ALLBUT contains contained
277
Bram Moolenaar4f99eae2010-07-24 15:56:43 +0200278 *hl-Ignore*
279When using the Ignore group, you may also consider using the conceal
280mechanism. See |conceal|.
281
Bram Moolenaar071d4272004-06-13 20:20:40 +0000282==============================================================================
2833. Syntax loading procedure *syntax-loading*
284
285This explains the details that happen when the command ":syntax enable" is
286issued. When Vim initializes itself, it finds out where the runtime files are
287located. This is used here as the variable |$VIMRUNTIME|.
288
289":syntax enable" and ":syntax on" do the following:
290
291 Source $VIMRUNTIME/syntax/syntax.vim
292 |
293 +- Clear out any old syntax by sourcing $VIMRUNTIME/syntax/nosyntax.vim
294 |
295 +- Source first syntax/synload.vim in 'runtimepath'
296 | |
297 | +- Setup the colors for syntax highlighting. If a color scheme is
298 | | defined it is loaded again with ":colors {name}". Otherwise
299 | | ":runtime! syntax/syncolor.vim" is used. ":syntax on" overrules
300 | | existing colors, ":syntax enable" only sets groups that weren't
301 | | set yet.
302 | |
303 | +- Set up syntax autocmds to load the appropriate syntax file when
304 | | the 'syntax' option is set. *synload-1*
305 | |
306 | +- Source the user's optional file, from the |mysyntaxfile| variable.
307 | This is for backwards compatibility with Vim 5.x only. *synload-2*
308 |
309 +- Do ":filetype on", which does ":runtime! filetype.vim". It loads any
310 | filetype.vim files found. It should always Source
311 | $VIMRUNTIME/filetype.vim, which does the following.
312 | |
313 | +- Install autocmds based on suffix to set the 'filetype' option
314 | | This is where the connection between file name and file type is
315 | | made for known file types. *synload-3*
316 | |
317 | +- Source the user's optional file, from the *myfiletypefile*
318 | | variable. This is for backwards compatibility with Vim 5.x only.
319 | | *synload-4*
320 | |
321 | +- Install one autocommand which sources scripts.vim when no file
322 | | type was detected yet. *synload-5*
323 | |
324 | +- Source $VIMRUNTIME/menu.vim, to setup the Syntax menu. |menu.vim|
325 |
326 +- Install a FileType autocommand to set the 'syntax' option when a file
327 | type has been detected. *synload-6*
328 |
329 +- Execute syntax autocommands to start syntax highlighting for each
330 already loaded buffer.
331
332
333Upon loading a file, Vim finds the relevant syntax file as follows:
334
335 Loading the file triggers the BufReadPost autocommands.
336 |
337 +- If there is a match with one of the autocommands from |synload-3|
338 | (known file types) or |synload-4| (user's file types), the 'filetype'
339 | option is set to the file type.
340 |
341 +- The autocommand at |synload-5| is triggered. If the file type was not
342 | found yet, then scripts.vim is searched for in 'runtimepath'. This
343 | should always load $VIMRUNTIME/scripts.vim, which does the following.
344 | |
345 | +- Source the user's optional file, from the *myscriptsfile*
346 | | variable. This is for backwards compatibility with Vim 5.x only.
347 | |
348 | +- If the file type is still unknown, check the contents of the file,
349 | again with checks like "getline(1) =~ pattern" as to whether the
350 | file type can be recognized, and set 'filetype'.
351 |
352 +- When the file type was determined and 'filetype' was set, this
353 | triggers the FileType autocommand |synload-6| above. It sets
354 | 'syntax' to the determined file type.
355 |
356 +- When the 'syntax' option was set above, this triggers an autocommand
357 | from |synload-1| (and |synload-2|). This find the main syntax file in
358 | 'runtimepath', with this command:
359 | runtime! syntax/<name>.vim
360 |
361 +- Any other user installed FileType or Syntax autocommands are
362 triggered. This can be used to change the highlighting for a specific
363 syntax.
364
365==============================================================================
3664. Syntax file remarks *:syn-file-remarks*
367
368 *b:current_syntax-variable*
369Vim stores the name of the syntax that has been loaded in the
370"b:current_syntax" variable. You can use this if you want to load other
371settings, depending on which syntax is active. Example: >
372 :au BufReadPost * if b:current_syntax == "csh"
373 :au BufReadPost * do-some-things
374 :au BufReadPost * endif
375
376
3772HTML *2html.vim* *convert-to-HTML*
378
379This is not a syntax file itself, but a script that converts the current
380window into HTML. Vim opens a new window in which it builds the HTML file.
381
382You are not supposed to set the 'filetype' or 'syntax' option to "2html"!
383Source the script to convert the current file: >
384
385 :runtime! syntax/2html.vim
386<
Bram Moolenaar071d4272004-06-13 20:20:40 +0000387 *:TOhtml*
388Or use the ":TOhtml" user command. It is defined in a standard plugin.
389":TOhtml" also works with a range and in a Visual area: >
390
391 :10,40TOhtml
392
Bram Moolenaar166af9b2010-11-16 20:34:40 +0100393Warning: This can be slow! The script must process every character of every
394line. Because it can take a long time, by default a progress bar is displayed
395in the statusline for each major step in the conversion process. If you don't
396like seeing this progress bar, you can disable it and get a very minor speed
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200397improvement with: >
398
399 let g:html_no_progress = 1
400
Bram Moolenaarb02cbe32010-07-11 22:38:52 +0200401":TOhtml" has another special feature: if the window is in diff mode, it will
402generate HTML that shows all the related windows. This can be disabled by
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200403setting the g:html_diff_one_file variable: >
Bram Moolenaarb02cbe32010-07-11 22:38:52 +0200404
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200405 let g:html_diff_one_file = 1
Bram Moolenaarb02cbe32010-07-11 22:38:52 +0200406
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100407After you save the resulting file, you can view it with any browser. The
408colors should be exactly the same as you see them in Vim.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000409
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200410To restrict the conversion to a range of lines, use a range with the |:TOhtml|
411command, or set "g:html_start_line" and "g:html_end_line" to the first and
412last line to be converted. Example, using the last set Visual area: >
Bram Moolenaar071d4272004-06-13 20:20:40 +0000413
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200414 :let g:html_start_line = line("'<")
415 :let g:html_end_line = line("'>")
Bram Moolenaar071d4272004-06-13 20:20:40 +0000416
417The lines are numbered according to 'number' option and the Number
418highlighting. You can force lines to be numbered in the HTML output by
419setting "html_number_lines" to non-zero value: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200420 :let g:html_number_lines = 1
Bram Moolenaar071d4272004-06-13 20:20:40 +0000421Force to omit the line numbers by using a zero value: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200422 :let g:html_number_lines = 0
Bram Moolenaar071d4272004-06-13 20:20:40 +0000423Go back to the default to use 'number' by deleting the variable: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200424 :unlet g:html_number_lines
Bram Moolenaar071d4272004-06-13 20:20:40 +0000425
Bram Moolenaar076e8b22010-08-05 21:54:00 +0200426By default, valid HTML 4.01 using cascading style sheets (CSS1) is generated.
427If you need to generate markup for really old browsers or some other user
428agent that lacks basic CSS support, use: >
429 :let g:html_use_css = 0

Bram Moolenaar7510fe72010-07-25 12:46:44 +0200431Concealed text is removed from the HTML and replaced with the appropriate
Bram Moolenaarfa0ff9a2010-07-25 16:05:19 +0200432character from |:syn-cchar| or 'listchars' depending on the current value of
Bram Moolenaar7510fe72010-07-25 12:46:44 +0200433'conceallevel'. If you always want to display all text in your document,
Bram Moolenaar8ada2cc2010-07-29 20:43:36 +0200434either set 'conceallevel' to zero before invoking 2html, or use: >
Bram Moolenaar7510fe72010-07-25 12:46:44 +0200435 :let g:html_ignore_conceal = 1
436
437Similarly, closed folds are put in the HTML as they are displayed. If you
438don't want this, use the |zR| command before invoking 2html, or use: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200439 :let g:html_ignore_folding = 1
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100440
441You may want to generate HTML that includes all the data within the folds, and
442allow the user to view the folded data similar to how they would in Vim. To
443generate this dynamic fold information, use: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200444 :let g:html_dynamic_folds = 1
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100445
446Using html_dynamic_folds will imply html_use_css, because it would be far too
447difficult to do it for old browsers. However, html_ignore_folding overrides
448html_dynamic_folds.
449
450Using html_dynamic_folds will default to generating a foldcolumn in the html
451similar to Vim's foldcolumn, that will use javascript to open and close the
452folds in the HTML document. The width of this foldcolumn starts at the current
453setting of |'foldcolumn'| but grows to fit the greatest foldlevel in your
454document. If you do not want to show a foldcolumn at all, use: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200455 :let g:html_no_foldcolumn = 1
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100456
457Using this option, there will be no foldcolumn available to open the folds in
458the HTML. For this reason, another option is provided: html_hover_unfold.
459Enabling this option will use CSS 2.0 to allow a user to open a fold by
460hovering the mouse pointer over it. Note that old browsers (notably Internet
461Explorer 6) will not support this feature. Browser-specific markup for IE6 is
462included to fall back to the normal CSS1 code so that the folds show up
463correctly for this browser, but they will not be openable without a
464foldcolumn. Note that using html_hover_unfold will allow modern browsers with
465disabled javascript to view closed folds. To use this option, use: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200466 :let g:html_hover_unfold = 1
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100467
468Setting html_no_foldcolumn with html_dynamic_folds will automatically set
469html_hover_unfold, because otherwise the folds wouldn't be dynamic.
470
Bram Moolenaar071d4272004-06-13 20:20:40 +0000471By default "<pre>" and "</pre>" is used around the text. This makes it show
472up as you see it in Vim, but without wrapping. If you prefer wrapping, at the
473risk of making some things look a bit different, use: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200474 :let g:html_no_pre = 1
Bram Moolenaar071d4272004-06-13 20:20:40 +0000475This will use <br> at the end of each line and use "&nbsp;" for repeated
476spaces.
477
Bram Moolenaar2a8a3ec2011-01-08 16:06:37 +0100478If you do use the "<pre>" tags, <Tab> characters in the text are included in
479the generated output if they will have no effect on the appearance of the
480text and it looks like they are in the document intentionally. This allows for
481the HTML output to be copied and pasted from a browser without losing the
482actual whitespace used in the document.
483
484Specifically, <Tab> characters will be included if the 'tabstop' option is set
485to the default of 8, 'expandtab' is not set, and if neither the foldcolumn nor
486the line numbers are included in the HTML output (see options above). When any
487of these conditions are not met, any <Tab> characters in the text are expanded
488to the appropriate number of spaces in the HTML output.
489
490When "<pre>" is included, you can force |:TOhtml| to keep the tabs even if the
491other conditions are not met with: >
492 :let g:html_expand_tabs = 0
493Note that this can easily break text alignment and indentation in the HTML.
494
495Force tabs to be expanded even when they would be kept using: >
496 :let g:html_expand_tabs = 1
497
Bram Moolenaar166af9b2010-11-16 20:34:40 +0100498For diff mode on a single file (with g:html_diff_one_file) a sequence of more
499than 3 filler lines is displayed as three lines with the middle line
500mentioning the total number of inserted lines. If you prefer to see all the
501inserted lines as with the side-by-side diff, use: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200502 :let g:html_whole_filler = 1
Bram Moolenaar47136d72004-10-12 20:02:24 +0000503And to go back to displaying up to three lines again: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200504 :unlet g:html_whole_filler
Bram Moolenaar488c6512005-08-11 20:09:58 +0000505<
Bram Moolenaar166af9b2010-11-16 20:34:40 +0100506TOhtml uses the current value of 'fileencoding' if set, or 'encoding' if not,
507to determine the charset and 'fileencoding' of the HTML file. In general, this
508works for the encodings mentioned specifically by name in |encoding-names|, but
509TOhtml will only automatically use those encodings which are widely supported.
510However, you can override this to support specific encodings that may not be
511automatically detected by default.
512
513To overrule all automatic charset detection, set g:html_use_encoding to the
514name of the charset to be used. TOhtml will try to determine the appropriate
515'fileencoding' setting from the charset, but you may need to set it manually
516if TOhtml cannot determine the encoding. It is recommended to set this
517variable to something widely supported, like UTF-8, for anything you will be
518hosting on a webserver: >
519 :let g:html_use_encoding = "UTF-8"
520You can also use this option to omit the line that specifies the charset
521entirely, by setting g:html_use_encoding to an empty string: >
522 :let g:html_use_encoding = ""
523To go back to the automatic mechanism, delete the g:html_use_encoding
524variable: >
525 :unlet g:html_use_encoding
526
527If you specify a charset with g:html_use_encoding for which TOhtml cannot
528automatically detect the corresponding 'fileencoding' setting, you can use
529g:html_encoding_override to allow TOhtml to detect the correct encoding.
530This is a dictionary of charset-encoding pairs that will replace existing
531pairs automatically detected by TOhtml, or supplement with new pairs. For
532example, to allow TOhtml to detect the HTML charset "windows-1252" properly as
533the encoding "8bit-cp1252", use: >
534 :let g:html_encoding_override = {'windows-1252': '8bit-cp1252'}
535<
536The g:html_charset_override is similar, it allows TOhtml to detect the HTML
537charset for any 'fileencoding' or 'encoding' which is not detected
538automatically. You can also use it to override specific existing
539encoding-charset pairs. For example, TOhtml will by default use UTF-8 for all
540Unicode/UCS encodings. To use UTF-16 and UTF-32 instead, use: >
541 :let g:html_charset_override = {'ucs-4': 'UTF-32', 'utf-16': 'UTF-16'}
542
543Note that documents encoded in either UTF-32 or UTF-16 have known
544compatibility problems with at least one major browser.

Bram Moolenaar166af9b2010-11-16 20:34:40 +0100547If you do not like plain HTML, an alternative is to have the script generate
548XHTML (XML compliant HTML). To do this set the "html_use_xhtml" variable: >

Bram Moolenaar166af9b2010-11-16 20:34:40 +0100551Any of the on/off options listed above can be enabled or disabled by setting
552them explicitly to the desired value, or restored to their default by removing
553the variable using |:unlet|.

555Remarks:
Bram Moolenaar076e8b22010-08-05 21:54:00 +0200556- Some truly ancient browsers may not show the background colors.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000557- From most browsers you can also print the file (in color)!
Bram Moolenaar166af9b2010-11-16 20:34:40 +0100558- This version of TOhtml may work with older versions of Vim, but some
559 features such as conceal support will not function, and the colors may be
560 incorrect for an old Vim without GUI support compiled in.

616Files matching "*.i" could be Progress or Assembly. If the automatic detection
617doesn't work for you, or you don't edit Progress at all, use this in your
618startup vimrc: >
619 :let filetype_i = "asm"
620Replace "asm" with the type of assembly you use.
621
622There are many types of assembly languages that all use the same file name
623extensions. Therefore you will have to select the type yourself, or add a
624line in the assembly file that Vim will recognize. Currently these syntax
625files are included:
626 asm GNU assembly (the default)
627 asm68k Motorola 680x0 assembly
628 asmh8300 Hitachi H-8300 version of GNU assembly
629 ia64 Intel Itanium 64
630 fasm Flat assembly (http://flatassembler.net)
631 masm Microsoft assembly (probably works for any 80x86)
632 nasm Netwide assembly
633 tasm Turbo Assembly (with opcodes 80x86 up to Pentium, and
634 MMX)
635 pic PIC assembly (currently for PIC16F84)
636
637The most flexible is to add a line in your assembly file containing: >
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100638 asmsyntax=nasm
Bram Moolenaar071d4272004-06-13 20:20:40 +0000639Replace "nasm" with the name of the real assembly syntax. This line must be
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100640one of the first five lines in the file. No non-white text must be
641immediately before or after this text.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000642
643The syntax type can always be overruled for a specific buffer by setting the
644b:asmsyntax variable: >
Bram Moolenaar8c8de832008-06-24 22:58:06 +0000645 :let b:asmsyntax = "nasm"
Bram Moolenaar071d4272004-06-13 20:20:40 +0000646
647If b:asmsyntax is not set, either automatically or by hand, then the value of
648the global variable asmsyntax is used. This can be seen as a default assembly
649language: >
Bram Moolenaar8c8de832008-06-24 22:58:06 +0000650 :let asmsyntax = "nasm"
Bram Moolenaar071d4272004-06-13 20:20:40 +0000651
652As a last resort, if nothing is defined, the "asm" syntax is used.

671*.asp and *.asa files could be either Perl or Visual Basic script. Since it's
672hard to detect this you can set two global variables to tell Vim what you are
673using. For Perl script use: >
674 :let g:filetype_asa = "aspperl"
675 :let g:filetype_asp = "aspperl"

684for both 3 GL and 4 GL programming. Large number of standard defines/constants
685are supported.

692
693Syntax folding can be enabled at various levels through the variables
694mentioned below (Set those in your |.vimrc|). The more complex folding on
695source blocks and SQL can be CPU intensive.
696
697To allow any folding and enable folding at function level use: >

Bram Moolenaar071d4272004-06-13 20:20:40 +0000715
716Both Visual Basic and "normal" basic use the extension ".bas". To detect
717which one should be used, Vim checks for the string "VB_Name" in the first
718five lines of the file. If it is not found, filetype will be "basic",
719otherwise "vb". Files with the ".frm" extension will always be seen as Visual
720Basic.

761This will make the syntax synchronization start 100 lines before the first
762displayed line. The default value is 50 (15 when c_no_if0 is set). The
763disadvantage of using a larger number is that redrawing can become slow.
764
765When using the "#if 0" / "#endif" comment highlighting, notice that this only
766works when the "#if 0" is within "c_minlines" from the top of the window. If
767you have a long "#if 0" construct it will not be highlighted correctly.
768
769To match extra items in comments, use the cCommentGroup cluster.
770Example: >
771 :au Syntax c call MyCadd()
772 :function MyCadd()
773 : syn keyword cMyItem contained Ni
774 : syn cluster cCommentGroup add=cMyItem
775 : hi link cMyItem Title
776 :endfun
777
778ANSI constants will be highlighted with the "cConstant" group. This includes
779"NULL", "SIG_IGN" and others. But not "TRUE", for example, because this is
780not in the ANSI standard. If you find this confusing, remove the cConstant
781highlighting: >
782 :hi link cConstant NONE
783
784If you see '{' and '}' highlighted as an error where they are OK, reset the
785highlighting for cErrInParen and cErrInBracket.
786
787If you want to use folding in your C files, you can add these lines in a file
Bram Moolenaar06b5d512010-05-22 15:37:44 +0200788in the "after" directory in 'runtimepath'. For Unix this would be
Bram Moolenaar071d4272004-06-13 20:20:40 +0000789~/.vim/after/syntax/c.vim. >

Bram Moolenaard4755bb2004-09-02 19:12:26 +0000794
795C/C++ interpreter. Ch has similar syntax highlighting to C and builds upon
796the C syntax file. See |c.vim| for all the settings that are available for C.
797
798By setting a variable you can tell Vim to use Ch syntax for *.h files, instead
799of C or C++: >
800 :let ch_syntax_for_h = 1

Bram Moolenaar071d4272004-06-13 20:20:40 +0000804
805Chill syntax highlighting is similar to C. See |c.vim| for all the settings
806that are available. Additionally there is:
807
Bram Moolenaar071d4272004-06-13 20:20:40 +0000808chill_space_errors like c_space_errors
809chill_comment_string like c_comment_strings

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000813CHANGELOG *changelog.vim* *ft-changelog-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000814
815ChangeLog supports highlighting spaces at the start of a line.
816If you do not like this, add following line to your .vimrc: >
817 let g:changelog_spacing_errors = 0
818This works the next time you edit a changelog file. You can also use
819"b:changelog_spacing_errors" to set this per buffer (before loading the syntax
820file).
821
822You can change the highlighting used, e.g., to flag the spaces as an error: >
823 :hi link ChangelogError Error
824Or to avoid the highlighting: >
825 :hi link ChangelogError NONE
826This works immediately.

Bram Moolenaar071d4272004-06-13 20:20:40 +0000830
831COBOL highlighting has different needs for legacy code than it does for fresh
832development. This is due to differences in what is being done (maintenance
833versus development) and other factors. To enable legacy code highlighting,
834add this line to your .vimrc: >
835 :let cobol_legacy_code = 1
836To disable it again, use this: >
837 :unlet cobol_legacy_code

Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000842The ColdFusion has its own version of HTML comments. To turn on ColdFusion
Bram Moolenaar071d4272004-06-13 20:20:40 +0000843comment highlighting, add the following line to your startup file: >
844
845 :let html_wrong_comments = 1
846
847The ColdFusion syntax file is based on the HTML syntax file.
848
849
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000850CSH *csh.vim* *ft-csh-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000851
852This covers the shell named "csh". Note that on some systems tcsh is actually
853used.
854
855Detecting whether a file is csh or tcsh is notoriously hard. Some systems
856symlink /bin/csh to /bin/tcsh, making it almost impossible to distinguish
857between csh and tcsh. In case VIM guesses wrong you can set the
858"filetype_csh" variable. For using csh: >
859
860 :let filetype_csh = "csh"
861
862For using tcsh: >
863
864 :let filetype_csh = "tcsh"
865
866Any script with a tcsh extension or a standard tcsh filename (.tcshrc,
867tcsh.tcshrc, tcsh.login) will have filetype tcsh. All other tcsh/csh scripts
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000868will be classified as tcsh, UNLESS the "filetype_csh" variable exists. If the
Bram Moolenaar071d4272004-06-13 20:20:40 +0000869"filetype_csh" variable exists, the filetype will be set to the value of the
870variable.

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000873CYNLIB *cynlib.vim* *ft-cynlib-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000874
875Cynlib files are C++ files that use the Cynlib class library to enable
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000876hardware modelling and simulation using C++. Typically Cynlib files have a .cc
Bram Moolenaar071d4272004-06-13 20:20:40 +0000877or a .cpp extension, which makes it very difficult to distinguish them from a
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000878normal C++ file. Thus, to enable Cynlib highlighting for .cc files, add this
Bram Moolenaar071d4272004-06-13 20:20:40 +0000879line to your .vimrc file: >
880
881 :let cynlib_cyntax_for_cc=1
882
883Similarly for cpp files (this extension is only usually used in Windows) >
884
885 :let cynlib_cyntax_for_cpp=1
886
887To disable these again, use this: >
888
889 :unlet cynlib_cyntax_for_cc

Bram Moolenaar071d4272004-06-13 20:20:40 +0000894
895Files matching "*.w" could be Progress or cweb. If the automatic detection
896doesn't work for you, or you don't edit Progress at all, use this in your
897startup vimrc: >
898 :let filetype_w = "cweb"

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000901DESKTOP *desktop.vim* *ft-desktop-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000902
903Primary goal of this syntax file is to highlight .desktop and .directory files
Bram Moolenaara17d4c12010-05-30 18:30:36 +0200904according to freedesktop.org standard:
905http://standards.freedesktop.org/desktop-entry-spec/latest/
Bram Moolenaar071d4272004-06-13 20:20:40 +0000906But actually almost none implements this standard fully. Thus it will
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000907highlight all Unix ini files. But you can force strict highlighting according
Bram Moolenaar071d4272004-06-13 20:20:40 +0000908to standard by placing this in your vimrc file: >
909 :let enforce_freedesktop_standard = 1

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000912DIRCOLORS *dircolors.vim* *ft-dircolors-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000913
914The dircolors utility highlighting definition has one option. It exists to
915provide compatibility with the Slackware GNU/Linux distributions version of
916the command. It adds a few keywords that are generally ignored by most
917versions. On Slackware systems, however, the utility accepts the keywords and
918uses them for processing. To enable the Slackware keywords add the following
919line to your startup file: >
920 let dircolors_is_slackware = 1
921

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000923DOCBOOK *docbk.vim* *ft-docbk-syntax* *docbook*

925DOCBOOK SGML *docbksgml.vim* *ft-docbksgml-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000926
927There are two types of DocBook files: SGML and XML. To specify what type you
928are using the "b:docbk_type" variable should be set. Vim does this for you
929automatically if it can recognize the type. When Vim can't guess it the type
930defaults to XML.
931You can set the type manually: >
932 :let docbk_type = "sgml"
933or: >
934 :let docbk_type = "xml"
935You need to do this before loading the syntax file, which is complicated.
936Simpler is setting the filetype to "docbkxml" or "docbksgml": >
937 :set filetype=docbksgml
938or: >
939 :set filetype=docbkxml
940

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000942DOSBATCH *dosbatch.vim* *ft-dosbatch-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000943
944There is one option with highlighting DOS batch files. This covers new
945extensions to the Command Interpreter introduced with Windows 2000 and
946is controlled by the variable dosbatch_cmdextversion. For Windows NT
947this should have the value 1, and for Windows 2000 it should be 2.
948Select the version you want with the following line: >
949
Bram Moolenaar8299df92004-07-10 09:47:34 +0000950 :let dosbatch_cmdextversion = 1
Bram Moolenaar071d4272004-06-13 20:20:40 +0000951
952If this variable is not defined it defaults to a value of 2 to support
953Windows 2000.
954
Bram Moolenaar8299df92004-07-10 09:47:34 +0000955A second option covers whether *.btm files should be detected as type
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000956"dosbatch" (MS-DOS batch files) or type "btm" (4DOS batch files). The latter
957is used by default. You may select the former with the following line: >
Bram Moolenaar8299df92004-07-10 09:47:34 +0000958
959 :let g:dosbatch_syntax_for_btm = 1
960
961If this variable is undefined or zero, btm syntax is selected.

Bram Moolenaar8cacf352006-04-15 20:27:24 +0000964DOXYGEN *doxygen.vim* *doxygen-syntax*
965
966Doxygen generates code documentation using a special documentation format
Bram Moolenaare37d50a2008-08-06 17:06:04 +0000967(similar to Javadoc). This syntax script adds doxygen highlighting to c, cpp,
968idl and php files, and should also work with java.
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000969
Bram Moolenaar25394022007-05-10 19:06:20 +0000970There are a few of ways to turn on doxygen formatting. It can be done
971explicitly or in a modeline by appending '.doxygen' to the syntax of the file.
972Example: >
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000973 :set syntax=c.doxygen
974or >
975 // vim:syntax=c.doxygen
976
Bram Moolenaar09092152010-08-08 16:38:42 +0200977It can also be done automatically for C, C++, C# and IDL files by setting the
Bram Moolenaar25394022007-05-10 19:06:20 +0000978global or buffer-local variable load_doxygen_syntax. This is done by adding
979the following to your .vimrc. >
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000980 :let g:load_doxygen_syntax=1
981
Bram Moolenaar06b5d512010-05-22 15:37:44 +0200982There are a couple of variables that have an effect on syntax highlighting, and
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000983are to do with non-standard highlighting options.
984
985Variable Default Effect ~
986g:doxygen_enhanced_color
987g:doxygen_enhanced_colour 0 Use non-standard highlighting for
988 doxygen comments.
989
990doxygen_my_rendering 0 Disable rendering of HTML bold, italic
991 and html_my_rendering underline.
992
993doxygen_javadoc_autobrief 1 Set to 0 to disable javadoc autobrief
994 colour highlighting.
995
996doxygen_end_punctuation '[.]' Set to regexp match for the ending
Bram Moolenaarc9b4b052006-04-30 18:54:39 +0000997 punctuation of brief
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000998
999There are also some hilight groups worth mentioning as they can be useful in
1000configuration.
1001
1002Highlight Effect ~
1003doxygenErrorComment The colour of an end-comment when missing
1004 punctuation in a code, verbatim or dot section
1005doxygenLinkError The colour of an end-comment when missing the
1006 \endlink from a \link section.

Bram Moolenaar071d4272004-06-13 20:20:40 +00001010
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001011The DTD syntax highlighting is case sensitive by default. To disable
Bram Moolenaar071d4272004-06-13 20:20:40 +00001012case-sensitive highlighting, add the following line to your startup file: >
1013
1014 :let dtd_ignore_case=1
1015
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001016The DTD syntax file will highlight unknown tags as errors. If
Bram Moolenaar071d4272004-06-13 20:20:40 +00001017this is annoying, it can be turned off by setting: >
1018
1019 :let dtd_no_tag_errors=1
1020
1021before sourcing the dtd.vim syntax file.
1022Parameter entity names are highlighted in the definition using the
1023'Type' highlighting group and 'Comment' for punctuation and '%'.
1024Parameter entity instances are highlighted using the 'Constant'
1025highlighting group and the 'Type' highlighting group for the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001026delimiters % and ;. This can be turned off by setting: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001027
1028 :let dtd_no_param_entities=1
1029
1030The DTD syntax file is also included by xml.vim to highlight included dtd's.

1032
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001033EIFFEL *eiffel.vim* *ft-eiffel-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001034
1035While Eiffel is not case-sensitive, its style guidelines are, and the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001036syntax highlighting file encourages their use. This also allows to
1037highlight class names differently. If you want to disable case-sensitive
Bram Moolenaar071d4272004-06-13 20:20:40 +00001038highlighting, add the following line to your startup file: >
1039
1040 :let eiffel_ignore_case=1
1041
1042Case still matters for class names and TODO marks in comments.
1043
1044Conversely, for even stricter checks, add one of the following lines: >
1045
1046 :let eiffel_strict=1
1047 :let eiffel_pedantic=1
1048
1049Setting eiffel_strict will only catch improper capitalization for the
1050five predefined words "Current", "Void", "Result", "Precursor", and
1051"NONE", to warn against their accidental use as feature or class names.
1052
1053Setting eiffel_pedantic will enforce adherence to the Eiffel style
1054guidelines fairly rigorously (like arbitrary mixes of upper- and
1055lowercase letters as well as outdated ways to capitalize keywords).
1056
1057If you want to use the lower-case version of "Current", "Void",
1058"Result", and "Precursor", you can use >
1059
1060 :let eiffel_lower_case_predef=1
1061
1062instead of completely turning case-sensitive highlighting off.
1063
1064Support for ISE's proposed new creation syntax that is already
1065experimentally handled by some compilers can be enabled by: >
1066
1067 :let eiffel_ise=1
1068
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001069Finally, some vendors support hexadecimal constants. To handle them, add >

1092
1093FlexWiki is an ASP.NET-based wiki package available at http://www.flexwiki.com
1094
1095Syntax highlighting is available for the most common elements of FlexWiki
1096syntax. The associated ftplugin script sets some buffer-local options to make
1097editing FlexWiki pages more convenient. FlexWiki considers a newline as the
1098start of a new paragraph, so the ftplugin sets 'tw'=0 (unlimited line length),
1099'wrap' (wrap long lines instead of using horizontal scrolling), 'linebreak'
1100(to wrap at a character in 'breakat' instead of at the last char on screen),
1101and so on. It also includes some keymaps that are disabled by default.
1102
1103If you want to enable the keymaps that make "j" and "k" and the cursor keys
1104move up and down by display lines, add this to your .vimrc: >

Bram Moolenaar071d4272004-06-13 20:20:40 +00001109
1110The coloring scheme for syntax elements in the FORM file uses the default
1111modes Conditional, Number, Statement, Comment, PreProc, Type, and String,
Bram Moolenaardd2a0d82007-05-12 15:07:00 +00001112following the language specifications in 'Symbolic Manipulation with FORM' by
Bram Moolenaar071d4272004-06-13 20:20:40 +00001113J.A.M. Vermaseren, CAN, Netherlands, 1991.
1114
1115If you want include your own changes to the default colors, you have to
1116redefine the following syntax groups:

1118 - formConditional
1119 - formNumber
1120 - formStatement
1121 - formHeaderStatement
1122 - formComment
1123 - formPreProc
1124 - formDirective
1125 - formType
1126 - formString
1127
1128Note that the form.vim syntax file implements FORM preprocessor commands and
1129directives per default in the same syntax group.
1130
1131A predefined enhanced color mode for FORM is available to distinguish between
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001132header statements and statements in the body of a FORM program. To activate
Bram Moolenaar071d4272004-06-13 20:20:40 +00001133this mode define the following variable in your vimrc file >
1134
1135 :let form_enhanced_color=1
1136
1137The enhanced mode also takes advantage of additional color features for a dark
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001138gvim display. Here, statements are colored LightYellow instead of Yellow, and
Bram Moolenaar071d4272004-06-13 20:20:40 +00001139conditionals are LightBlue for better distinction.

Bram Moolenaar071d4272004-06-13 20:20:40 +00001143
1144Default highlighting and dialect ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001145Highlighting appropriate for f95 (Fortran 95) is used by default. This choice
Bram Moolenaar071d4272004-06-13 20:20:40 +00001146should be appropriate for most users most of the time because Fortran 95 is a
Bram Moolenaar365bdf72010-07-24 20:57:44 +02001147superset of Fortran 90 and almost a superset of Fortran 77. Support for
1148Fortran 2003 and Fortran 2008 features has been introduced and is
Bram Moolenaare06c1882010-07-21 22:05:20 +02001149automatically available in the default (f95) highlighting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001150
1151Fortran source code form ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001152Fortran 9x code can be in either fixed or free source form. Note that the
Bram Moolenaar071d4272004-06-13 20:20:40 +00001153syntax highlighting will not be correct if the form is incorrectly set.
1154
1155When you create a new fortran file, the syntax script assumes fixed source
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001156form. If you always use free source form, then >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001157 :let fortran_free_source=1
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001158in your .vimrc prior to the :syntax on command. If you always use fixed source
Bram Moolenaar071d4272004-06-13 20:20:40 +00001159form, then >
1160 :let fortran_fixed_source=1
1161in your .vimrc prior to the :syntax on command.
1162
1163If the form of the source code depends upon the file extension, then it is
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001164most convenient to set fortran_free_source in a ftplugin file. For more
1165information on ftplugin files, see |ftplugin|. For example, if all your
Bram Moolenaar071d4272004-06-13 20:20:40 +00001166fortran files with an .f90 extension are written in free source form and the
1167rest in fixed source form, add the following code to your ftplugin file >
1168 let s:extfname = expand("%:e")
1169 if s:extfname ==? "f90"
1170 let fortran_free_source=1
1171 unlet! fortran_fixed_source
1172 else
1173 let fortran_fixed_source=1
1174 unlet! fortran_free_source
1175 endif
1176Note that this will work only if the "filetype plugin indent on" command
1177precedes the "syntax on" command in your .vimrc file.
1178
1179When you edit an existing fortran file, the syntax script will assume free
1180source form if the fortran_free_source variable has been set, and assumes
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001181fixed source form if the fortran_fixed_source variable has been set. If
Bram Moolenaar071d4272004-06-13 20:20:40 +00001182neither of these variables have been set, the syntax script attempts to
1183determine which source form has been used by examining the first five columns
Bram Moolenaar910f66f2006-04-05 20:41:53 +00001184of the first 250 lines of your file. If no signs of free source form are
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001185detected, then the file is assumed to be in fixed source form. The algorithm
1186should work in the vast majority of cases. In some cases, such as a file that
Bram Moolenaar910f66f2006-04-05 20:41:53 +00001187begins with 250 or more full-line comments, the script may incorrectly decide
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001188that the fortran code is in fixed form. If that happens, just add a
Bram Moolenaar071d4272004-06-13 20:20:40 +00001189non-comment statement beginning anywhere in the first five columns of the
1190first twenty five lines, save (:w) and then reload (:e!) the file.
1191
1192Tabs in fortran files ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001193Tabs are not recognized by the Fortran standards. Tabs are not a good idea in
Bram Moolenaar071d4272004-06-13 20:20:40 +00001194fixed format fortran source code which requires fixed column boundaries.
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001195Therefore, tabs are marked as errors. Nevertheless, some programmers like
1196using tabs. If your fortran files contain tabs, then you should set the
Bram Moolenaar071d4272004-06-13 20:20:40 +00001197variable fortran_have_tabs in your .vimrc with a command such as >
1198 :let fortran_have_tabs=1
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001199placed prior to the :syntax on command. Unfortunately, the use of tabs will
Bram Moolenaar071d4272004-06-13 20:20:40 +00001200mean that the syntax file will not be able to detect incorrect margins.
1201
1202Syntax folding of fortran files ~
1203If you wish to use foldmethod=syntax, then you must first set the variable
1204fortran_fold with a command such as >
1205 :let fortran_fold=1
1206to instruct the syntax script to define fold regions for program units, that
1207is main programs starting with a program statement, subroutines, function
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001208subprograms, block data subprograms, interface blocks, and modules. If you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001209also set the variable fortran_fold_conditionals with a command such as >
1210 :let fortran_fold_conditionals=1
1211then fold regions will also be defined for do loops, if blocks, and select
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001212case constructs. If you also set the variable
Bram Moolenaar071d4272004-06-13 20:20:40 +00001213fortran_fold_multilinecomments with a command such as >
1214 :let fortran_fold_multilinecomments=1
1215then fold regions will also be defined for three or more consecutive comment
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001216lines. Note that defining fold regions can be slow for large files.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001217
1218If fortran_fold, and possibly fortran_fold_conditionals and/or
1219fortran_fold_multilinecomments, have been set, then vim will fold your file if
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001220you set foldmethod=syntax. Comments or blank lines placed between two program
Bram Moolenaar071d4272004-06-13 20:20:40 +00001221units are not folded because they are seen as not belonging to any program
1222unit.
1223
1224More precise fortran syntax ~
1225If you set the variable fortran_more_precise with a command such as >
1226 :let fortran_more_precise=1
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001227then the syntax coloring will be more precise but slower. In particular,
Bram Moolenaar071d4272004-06-13 20:20:40 +00001228statement labels used in do, goto and arithmetic if statements will be
1229recognized, as will construct names at the end of a do, if, select or forall
1230construct.
1231
1232Non-default fortran dialects ~
1233The syntax script supports five Fortran dialects: f95, f90, f77, the Lahey
1234subset elf90, and the Imagine1 subset F.
1235
1236If you use f77 with extensions, even common ones like do/enddo loops, do/while
1237loops and free source form that are supported by most f77 compilers including
1238g77 (GNU Fortran), then you will probably find the default highlighting
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001239satisfactory. However, if you use strict f77 with no extensions, not even free
Bram Moolenaar071d4272004-06-13 20:20:40 +00001240source form or the MIL STD 1753 extensions, then the advantages of setting the
1241dialect to f77 are that names such as SUM are recognized as user variable
1242names and not highlighted as f9x intrinsic functions, that obsolete constructs
1243such as ASSIGN statements are not highlighted as todo items, and that fixed
1244source form will be assumed.
1245
1246If you use elf90 or F, the advantage of setting the dialect appropriately is
1247that f90 features excluded from these dialects will be highlighted as todo
1248items and that free source form will be assumed as required for these
1249dialects.
1250
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001251The dialect can be selected by setting the variable fortran_dialect. The
Bram Moolenaar071d4272004-06-13 20:20:40 +00001252permissible values of fortran_dialect are case-sensitive and must be "f95",
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001253"f90", "f77", "elf" or "F". Invalid values of fortran_dialect are ignored.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001254
1255If all your fortran files use the same dialect, set fortran_dialect in your
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001256.vimrc prior to your syntax on statement. If the dialect depends upon the file
1257extension, then it is most convenient to set it in a ftplugin file. For more
1258information on ftplugin files, see |ftplugin|. For example, if all your
Bram Moolenaar071d4272004-06-13 20:20:40 +00001259fortran files with an .f90 extension are written in the elf subset, your
1260ftplugin file should contain the code >
1261 let s:extfname = expand("%:e")
1262 if s:extfname ==? "f90"
1263 let fortran_dialect="elf"
1264 else
1265 unlet! fortran_dialect
1266 endif
1267Note that this will work only if the "filetype plugin indent on" command
1268precedes the "syntax on" command in your .vimrc file.
1269
1270Finer control is necessary if the file extension does not uniquely identify
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001271the dialect. You can override the default dialect, on a file-by-file basis, by
Bram Moolenaar071d4272004-06-13 20:20:40 +00001272including a comment with the directive "fortran_dialect=xx" (where xx=f77 or
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001273elf or F or f90 or f95) in one of the first three lines in your file. For
Bram Moolenaar071d4272004-06-13 20:20:40 +00001274example, your older .f files may be written in extended f77 but your newer
1275ones may be F codes, and you would identify the latter by including in the
1276first three lines of those files a Fortran comment of the form >
1277 ! fortran_dialect=F
1278F overrides elf if both directives are present.
1279
1280Limitations ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001281Parenthesis checking does not catch too few closing parentheses. Hollerith
1282strings are not recognized. Some keywords may be highlighted incorrectly
Bram Moolenaar071d4272004-06-13 20:20:40 +00001283because Fortran90 has no reserved words.
1284
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001285For further information related to fortran, see |ft-fortran-indent| and
1286|ft-fortran-plugin|.

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001289FVWM CONFIGURATION FILES *fvwm.vim* *ft-fvwm-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001290
1291In order for Vim to recognize Fvwm configuration files that do not match
1292the patterns *fvwmrc* or *fvwm2rc* , you must put additional patterns
1293appropriate to your system in your myfiletypes.vim file. For these
1294patterns, you must set the variable "b:fvwm_version" to the major version
1295number of Fvwm, and the 'filetype' option to fvwm.
1296
1297For example, to make Vim identify all files in /etc/X11/fvwm2/
1298as Fvwm2 configuration files, add the following: >
1299
1300 :au! BufNewFile,BufRead /etc/X11/fvwm2/* let b:fvwm_version = 2 |
1301 \ set filetype=fvwm
1302
1303If you'd like Vim to highlight all valid color names, tell it where to
1304find the color database (rgb.txt) on your system. Do this by setting
1305"rgb_file" to its location. Assuming your color database is located
1306in /usr/X11/lib/X11/, you should add the line >
1307
1308 :let rgb_file = "/usr/X11/lib/X11/rgb.txt"
1309
1310to your .vimrc file.
1311
1312
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001313GSP *gsp.vim* *ft-gsp-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001314
1315The default coloring style for GSP pages is defined by |html.vim|, and
1316the coloring for java code (within java tags or inline between backticks)
1317is defined by |java.vim|. The following HTML groups defined in |html.vim|
1318are redefined to incorporate and highlight inline java code:
1319
1320 htmlString
1321 htmlValue
1322 htmlEndTag
1323 htmlTag
1324 htmlTagN
1325
1326Highlighting should look fine most of the places where you'd see inline
1327java code, but in some special cases it may not. To add another HTML
1328group where you will have inline java code where it does not highlight
1329correctly, just copy the line you want from |html.vim| and add gspJava
1330to the contains clause.
1331
1332The backticks for inline java are highlighted according to the htmlError
1333group to make them easier to see.
1334
1335
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001336GROFF *groff.vim* *ft-groff-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001337
1338The groff syntax file is a wrapper for |nroff.vim|, see the notes
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001339under that heading for examples of use and configuration. The purpose
Bram Moolenaar071d4272004-06-13 20:20:40 +00001340of this wrapper is to set up groff syntax extensions by setting the
1341filetype from a |modeline| or in a personal filetype definitions file
1342(see |filetype.txt|).
1343
1344
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001345HASKELL *haskell.vim* *lhaskell.vim* *ft-haskell-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001346
1347The Haskell syntax files support plain Haskell code as well as literate
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001348Haskell code, the latter in both Bird style and TeX style. The Haskell
Bram Moolenaar071d4272004-06-13 20:20:40 +00001349syntax highlighting will also highlight C preprocessor directives.
1350
1351If you want to highlight delimiter characters (useful if you have a
1352light-coloured background), add to your .vimrc: >
1353 :let hs_highlight_delimiters = 1
1354To treat True and False as keywords as opposed to ordinary identifiers,
1355add: >
1356 :let hs_highlight_boolean = 1
1357To also treat the names of primitive types as keywords: >
1358 :let hs_highlight_types = 1
1359And to treat the names of even more relatively common types as keywords: >
1360 :let hs_highlight_more_types = 1
1361If you want to highlight the names of debugging functions, put in
1362your .vimrc: >
1363 :let hs_highlight_debug = 1
1364
1365The Haskell syntax highlighting also highlights C preprocessor
1366directives, and flags lines that start with # but are not valid
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001367directives as erroneous. This interferes with Haskell's syntax for
1368operators, as they may start with #. If you want to highlight those
Bram Moolenaar071d4272004-06-13 20:20:40 +00001369as operators as opposed to errors, put in your .vimrc: >
1370 :let hs_allow_hash_operator = 1
1371
1372The syntax highlighting for literate Haskell code will try to
1373automatically guess whether your literate Haskell code contains
1374TeX markup or not, and correspondingly highlight TeX constructs
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001375or nothing at all. You can override this globally by putting
Bram Moolenaar071d4272004-06-13 20:20:40 +00001376in your .vimrc >
1377 :let lhs_markup = none
1378for no highlighting at all, or >
1379 :let lhs_markup = tex
1380to force the highlighting to always try to highlight TeX markup.
1381For more flexibility, you may also use buffer local versions of
1382this variable, so e.g. >
1383 :let b:lhs_markup = tex
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001384will force TeX highlighting for a particular buffer. It has to be
Bram Moolenaar071d4272004-06-13 20:20:40 +00001385set before turning syntax highlighting on for the buffer or
1386loading a file.
1387
1388
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001389HTML *html.vim* *ft-html-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001390
1391The coloring scheme for tags in the HTML file works as follows.
1392
1393The <> of opening tags are colored differently than the </> of a closing tag.
1394This is on purpose! For opening tags the 'Function' color is used, while for
1395closing tags the 'Type' color is used (See syntax.vim to check how those are
1396defined for you)
1397
1398Known tag names are colored the same way as statements in C. Unknown tag
1399names are colored with the same color as the <> or </> respectively which
1400makes it easy to spot errors
1401
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001402Note that the same is true for argument (or attribute) names. Known attribute
Bram Moolenaar071d4272004-06-13 20:20:40 +00001403names are colored differently than unknown ones.
1404
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001405Some HTML tags are used to change the rendering of text. The following tags
Bram Moolenaar071d4272004-06-13 20:20:40 +00001406are recognized by the html.vim syntax coloring file and change the way normal
1407text is shown: <B> <I> <U> <EM> <STRONG> (<EM> is used as an alias for <I>,
1408while <STRONG> as an alias for <B>), <H1> - <H6>, <HEAD>, <TITLE> and <A>, but
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001409only if used as a link (that is, it must include a href as in
Bram Moolenaar25394022007-05-10 19:06:20 +00001410<A href="somefile.html">).
Bram Moolenaar071d4272004-06-13 20:20:40 +00001411
1412If you want to change how such text is rendered, you must redefine the
1413following syntax groups:
1414
1415 - htmlBold
1416 - htmlBoldUnderline
1417 - htmlBoldUnderlineItalic
1418 - htmlUnderline
1419 - htmlUnderlineItalic
1420 - htmlItalic
1421 - htmlTitle for titles
1422 - htmlH1 - htmlH6 for headings
1423
1424To make this redefinition work you must redefine them all with the exception
1425of the last two (htmlTitle and htmlH[1-6], which are optional) and define the
1426following variable in your vimrc (this is due to the order in which the files
1427are read during initialization) >
1428 :let html_my_rendering=1
1429
1430If you'd like to see an example download mysyntax.vim at
1431http://www.fleiner.com/vim/download.html
1432
1433You can also disable this rendering by adding the following line to your
1434vimrc file: >
1435 :let html_no_rendering=1
1436
1437HTML comments are rather special (see an HTML reference document for the
1438details), and the syntax coloring scheme will highlight all errors.
1439However, if you prefer to use the wrong style (starts with <!-- and
1440ends with --!>) you can define >
1441 :let html_wrong_comments=1
1442
1443JavaScript and Visual Basic embedded inside HTML documents are highlighted as
1444'Special' with statements, comments, strings and so on colored as in standard
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001445programming languages. Note that only JavaScript and Visual Basic are currently
Bram Moolenaar071d4272004-06-13 20:20:40 +00001446supported, no other scripting language has been added yet.
1447
1448Embedded and inlined cascading style sheets (CSS) are highlighted too.
1449
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001450There are several html preprocessor languages out there. html.vim has been
1451written such that it should be trivial to include it. To do so add the
Bram Moolenaar071d4272004-06-13 20:20:40 +00001452following two lines to the syntax coloring file for that language
1453(the example comes from the asp.vim file):
1454
1455 runtime! syntax/html.vim
1456 syn cluster htmlPreproc add=asp
1457
1458Now you just need to make sure that you add all regions that contain
1459the preprocessor language to the cluster htmlPreproc.

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001462HTML/OS (by Aestiva) *htmlos.vim* *ft-htmlos-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001463
1464The coloring scheme for HTML/OS works as follows:
1465
1466Functions and variable names are the same color by default, because VIM
1467doesn't specify different colors for Functions and Identifiers. To change
1468this (which is recommended if you want function names to be recognizable in a
1469different color) you need to add the following line to either your ~/.vimrc: >
1470 :hi Function term=underline cterm=bold ctermfg=LightGray
1471
1472Of course, the ctermfg can be a different color if you choose.
1473
1474Another issues that HTML/OS runs into is that there is no special filetype to
1475signify that it is a file with HTML/OS coding. You can change this by opening
1476a file and turning on HTML/OS syntax by doing the following: >
1477 :set syntax=htmlos
1478
1479Lastly, it should be noted that the opening and closing characters to begin a
1480block of HTML/OS code can either be << or [[ and >> or ]], respectively.

Bram Moolenaar071d4272004-06-13 20:20:40 +00001484
1485Highlighting for the Intel Itanium 64 assembly language. See |asm.vim| for
1486how to recognize this filetype.
1487
1488To have *.inc files be recognized as IA64, add this to your .vimrc file: >
1489 :let g:filetype_inc = "ia64"
1490
1491
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001492INFORM *inform.vim* *ft-inform-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001493
1494Inform highlighting includes symbols provided by the Inform Library, as
1495most programs make extensive use of it. If do not wish Library symbols
1496to be highlighted add this to your vim startup: >
1497 :let inform_highlight_simple=1
1498
1499By default it is assumed that Inform programs are Z-machine targeted,
1500and highlights Z-machine assembly language symbols appropriately. If
1501you intend your program to be targeted to a Glulx/Glk environment you
1502need to add this to your startup sequence: >
1503 :let inform_highlight_glulx=1
1504
1505This will highlight Glulx opcodes instead, and also adds glk() to the
1506set of highlighted system functions.
1507
1508The Inform compiler will flag certain obsolete keywords as errors when
1509it encounters them. These keywords are normally highlighted as errors
1510by Vim. To prevent such error highlighting, you must add this to your
1511startup sequence: >
1512 :let inform_suppress_obsolete=1
1513
1514By default, the language features highlighted conform to Compiler
1515version 6.30 and Library version 6.11. If you are using an older
1516Inform development environment, you may with to add this to your
1517startup sequence: >
1518 :let inform_highlight_old=1

Bram Moolenaar9e54a0e2006-04-14 20:42:25 +00001520IDL *idl.vim* *idl-syntax*
1521
1522IDL (Interface Definition Language) files are used to define RPC calls. In
1523Microsoft land, this is also used for defining COM interfaces and calls.
1524
1525IDL's structure is simple enough to permit a full grammar based approach to
1526rather than using a few heuristics. The result is large and somewhat
Bram Moolenaar25394022007-05-10 19:06:20 +00001527repetitive but seems to work.
Bram Moolenaar9e54a0e2006-04-14 20:42:25 +00001528
1529There are some Microsoft extensions to idl files that are here. Some of them
1530are disabled by defining idl_no_ms_extensions.
1531
1532The more complex of the extensions are disabled by defining idl_no_extensions.
1533
1534Variable Effect ~
1535
1536idl_no_ms_extensions Disable some of the Microsoft specific
1537 extensions
1538idl_no_extensions Disable complex extensions

1540 quite helpful)

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001544JAVA *java.vim* *ft-java-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001545
1546The java.vim syntax highlighting file offers several options:
1547
1548In Java 1.0.2 it was never possible to have braces inside parens, so this was
1549flagged as an error. Since Java 1.1 this is possible (with anonymous
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001550classes), and therefore is no longer marked as an error. If you prefer the old
Bram Moolenaar071d4272004-06-13 20:20:40 +00001551way, put the following line into your vim startup file: >
1552 :let java_mark_braces_in_parens_as_errors=1
1553
1554All identifiers in java.lang.* are always visible in all classes. To
1555highlight them use: >
1556 :let java_highlight_java_lang_ids=1
1557
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001558You can also highlight identifiers of most standard Java packages if you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001559download the javaid.vim script at http://www.fleiner.com/vim/download.html.
1560If you prefer to only highlight identifiers of a certain package, say java.io
1561use the following: >
1562 :let java_highlight_java_io=1
1563Check the javaid.vim file for a list of all the packages that are supported.
1564
1565Function names are not highlighted, as the way to find functions depends on
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001566how you write Java code. The syntax file knows two possible ways to highlight
Bram Moolenaar071d4272004-06-13 20:20:40 +00001567functions:
1568
1569If you write function declarations that are always indented by either
1570a tab, 8 spaces or 2 spaces you may want to set >
1571 :let java_highlight_functions="indent"
1572However, if you follow the Java guidelines about how functions and classes are
1573supposed to be named (with respect to upper and lowercase), use >
1574 :let java_highlight_functions="style"
1575If both options do not work for you, but you would still want function
1576declarations to be highlighted create your own definitions by changing the
1577definitions in java.vim or by creating your own java.vim which includes the
1578original one and then adds the code to highlight functions.
1579
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001580In Java 1.1 the functions System.out.println() and System.err.println() should
Bram Moolenaared203462004-06-16 11:19:22 +00001581only be used for debugging. Therefore it is possible to highlight debugging
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001582statements differently. To do this you must add the following definition in
Bram Moolenaar071d4272004-06-13 20:20:40 +00001583your startup file: >
1584 :let java_highlight_debug=1
1585The result will be that those statements are highlighted as 'Special'
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001586characters. If you prefer to have them highlighted differently you must define
Bram Moolenaar071d4272004-06-13 20:20:40 +00001587new highlightings for the following groups.:
1588 Debug, DebugSpecial, DebugString, DebugBoolean, DebugType
1589which are used for the statement itself, special characters used in debug
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001590strings, strings, boolean constants and types (this, super) respectively. I
Bram Moolenaar071d4272004-06-13 20:20:40 +00001591have opted to chose another background for those statements.
1592
Bram Moolenaar8c8de832008-06-24 22:58:06 +00001593In order to help you write code that can be easily ported between Java and
1594C++, all C++ keywords can be marked as an error in a Java program. To
1595have this add this line in your .vimrc file: >
1596 :let java_allow_cpp_keywords = 0
Bram Moolenaar071d4272004-06-13 20:20:40 +00001597
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001598Javadoc is a program that takes special comments out of Java program files and
1599creates HTML pages. The standard configuration will highlight this HTML code
1600similarly to HTML files (see |html.vim|). You can even add Javascript
1601and CSS inside this code (see below). There are four differences however:
Bram Moolenaar071d4272004-06-13 20:20:40 +00001602 1. The title (all characters up to the first '.' which is followed by
1603 some white space or up to the first '@') is colored differently (to change
1604 the color change the group CommentTitle).
1605 2. The text is colored as 'Comment'.
1606 3. HTML comments are colored as 'Special'
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001607 4. The special Javadoc tags (@see, @param, ...) are highlighted as specials
Bram Moolenaar071d4272004-06-13 20:20:40 +00001608 and the argument (for @see, @param, @exception) as Function.
1609To turn this feature off add the following line to your startup file: >
1610 :let java_ignore_javadoc=1
1611
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001612If you use the special Javadoc comment highlighting described above you
1613can also turn on special highlighting for Javascript, visual basic
1614scripts and embedded CSS (stylesheets). This makes only sense if you
1615actually have Javadoc comments that include either Javascript or embedded
1616CSS. The options to use are >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001617 :let java_javascript=1
1618 :let java_css=1
1619 :let java_vb=1
1620
1621In order to highlight nested parens with different colors define colors
1622for javaParen, javaParen1 and javaParen2, for example with >
1623 :hi link javaParen Comment
1624or >
1625 :hi javaParen ctermfg=blue guifg=#0000ff
1626
1627If you notice highlighting errors while scrolling backwards, which are fixed
1628when redrawing with CTRL-L, try setting the "java_minlines" internal variable
1629to a larger number: >
1630 :let java_minlines = 50
1631This will make the syntax synchronization start 50 lines before the first
1632displayed line. The default value is 10. The disadvantage of using a larger
1633number is that redrawing can become slow.
1634
1635
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001636LACE *lace.vim* *ft-lace-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001637
1638Lace (Language for Assembly of Classes in Eiffel) is case insensitive, but the
1639style guide lines are not. If you prefer case insensitive highlighting, just
1640define the vim variable 'lace_case_insensitive' in your startup file: >
1641 :let lace_case_insensitive=1
1642
1643
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001644LEX *lex.vim* *ft-lex-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001645
1646Lex uses brute-force synchronizing as the "^%%$" section delimiter
1647gives no clue as to what section follows. Consequently, the value for >
1648 :syn sync minlines=300
1649may be changed by the user if s/he is experiencing synchronization
1650difficulties (such as may happen with large lex files).

Bram Moolenaar6fc45b52010-07-25 17:42:45 +02001653LIFELINES *lifelines.vim* *ft-lifelines-syntax*
1654
1655To highlight deprecated functions as errors, add in your .vimrc: >
1656
1657 :let g:lifelines_deprecated = 1
1658<
1659
Bram Moolenaara5fac542005-10-12 20:58:49 +00001660LISP *lisp.vim* *ft-lisp-syntax*
1661
1662The lisp syntax highlighting provides two options: >
1663
1664 g:lisp_instring : if it exists, then "(...)" strings are highlighted
1665 as if the contents of the string were lisp.
1666 Useful for AutoLisp.
1667 g:lisp_rainbow : if it exists and is nonzero, then differing levels
1668 of parenthesization will receive different
1669 highlighting.
1670<
1671The g:lisp_rainbow option provides 10 levels of individual colorization for
1672the parentheses and backquoted parentheses. Because of the quantity of
1673colorization levels, unlike non-rainbow highlighting, the rainbow mode
1674specifies its highlighting using ctermfg and guifg, thereby bypassing the
1675usual colorscheme control using standard highlighting groups. The actual
1676highlighting used depends on the dark/bright setting (see |'bg'|).
1677
1678
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001679LITE *lite.vim* *ft-lite-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001680
1681There are two options for the lite syntax highlighting.
1682
1683If you like SQL syntax highlighting inside Strings, use this: >
1684
1685 :let lite_sql_query = 1
1686
1687For syncing, minlines defaults to 100. If you prefer another value, you can
1688set "lite_minlines" to the value you desire. Example: >
1689
1690 :let lite_minlines = 200

Bram Moolenaar071d4272004-06-13 20:20:40 +00001694
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001695LPC stands for a simple, memory-efficient language: Lars Pensj| C. The
Bram Moolenaar071d4272004-06-13 20:20:40 +00001696file name of LPC is usually *.c. Recognizing these files as LPC would bother
1697users writing only C programs. If you want to use LPC syntax in Vim, you
1698should set a variable in your .vimrc file: >
1699
1700 :let lpc_syntax_for_c = 1
1701
1702If it doesn't work properly for some particular C or LPC files, use a
1703modeline. For a LPC file:
1704
1705 // vim:set ft=lpc:
1706
1707For a C file that is recognized as LPC:
1708
1709 // vim:set ft=c:
1710
1711If you don't want to set the variable, use the modeline in EVERY LPC file.
1712
1713There are several implementations for LPC, we intend to support most widely
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001714used ones. Here the default LPC syntax is for MudOS series, for MudOS v22
Bram Moolenaar071d4272004-06-13 20:20:40 +00001715and before, you should turn off the sensible modifiers, and this will also
1716asserts the new efuns after v22 to be invalid, don't set this variable when
1717you are using the latest version of MudOS: >
1718
1719 :let lpc_pre_v22 = 1
1720
1721For LpMud 3.2 series of LPC: >

1725For LPC4 series of LPC: >
1726
1727 :let lpc_use_lpc4_syntax = 1
1728
1729For uLPC series of LPC:
1730uLPC has been developed to Pike, so you should use Pike syntax
1731instead, and the name of your source file should be *.pike

Bram Moolenaarfc1421e2006-04-20 22:17:20 +00001736This syntax file may be used for Lua 4.0, Lua 5.0 or Lua 5.1 (the latter is
1737the default). You can select one of these versions using the global variables
1738lua_version and lua_subversion. For example, to activate Lua
17394.0 syntax highlighting, use this command: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001740
1741 :let lua_version = 4
1742

Bram Moolenaar071d4272004-06-13 20:20:40 +00001755
1756Vim highlights all the standard elements of an email (headers, signatures,
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001757quoted text and URLs / email addresses). In keeping with standard conventions,
Bram Moolenaar071d4272004-06-13 20:20:40 +00001758signatures begin in a line containing only "--" followed optionally by
1759whitespaces and end with a newline.
1760
1761Vim treats lines beginning with ']', '}', '|', '>' or a word followed by '>'
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001762as quoted text. However Vim highlights headers and signatures in quoted text
Bram Moolenaar071d4272004-06-13 20:20:40 +00001763only if the text is quoted with '>' (optionally followed by one space).
1764
1765By default mail.vim synchronises syntax to 100 lines before the first
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001766displayed line. If you have a slow machine, and generally deal with emails
Bram Moolenaar071d4272004-06-13 20:20:40 +00001767with short headers, you can change this to a smaller value: >

1783Maple V, by Waterloo Maple Inc, supports symbolic algebra. The language
1784supports many packages of functions which are selectively loaded by the user.
1785The standard set of packages' functions as supplied in Maple V release 4 may be
1786highlighted at the user's discretion. Users may place in their .vimrc file: >
1787
1788 :let mvpkg_all= 1
1789

Bram Moolenaar071d4272004-06-13 20:20:40 +00001851
1852There are two options for the msql syntax highlighting.
1853
1854If you like SQL syntax highlighting inside Strings, use this: >
1855
1856 :let msql_sql_query = 1
1857
1858For syncing, minlines defaults to 100. If you prefer another value, you can
1859set "msql_minlines" to the value you desire. Example: >
1860
1861 :let msql_minlines = 200

Bram Moolenaar071d4272004-06-13 20:20:40 +00001865
1866There is one option for NCF syntax highlighting.
1867
1868If you want to have unrecognized (by ncf.vim) statements highlighted as
1869errors, use this: >
1870
1871 :let ncf_highlight_unknowns = 1
1872
1873If you don't want to highlight these errors, leave it unset.
1874
1875
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001876NROFF *nroff.vim* *ft-nroff-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001877
1878The nroff syntax file works with AT&T n/troff out of the box. You need to
1879activate the GNU groff extra features included in the syntax file before you
1880can use them.
1881
1882For example, Linux and BSD distributions use groff as their default text
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001883processing package. In order to activate the extra syntax highlighting
Bram Moolenaar071d4272004-06-13 20:20:40 +00001884features for groff, add the following option to your start-up files: >
1885
1886 :let b:nroff_is_groff = 1
1887
1888Groff is different from the old AT&T n/troff that you may still find in
1889Solaris. Groff macro and request names can be longer than 2 characters and
1890there are extensions to the language primitives. For example, in AT&T troff
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001891you access the year as a 2-digit number with the request \(yr. In groff you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001892can use the same request, recognized for compatibility, or you can use groff's
1893native syntax, \[yr]. Furthermore, you can use a 4-digit year directly:
1894\[year]. Macro requests can be longer than 2 characters, for example, GNU mm
1895accepts the requests ".VERBON" and ".VERBOFF" for creating verbatim
1896environments.
1897
1898In order to obtain the best formatted output g/troff can give you, you should
1899follow a few simple rules about spacing and punctuation.
1900
19011. Do not leave empty spaces at the end of lines.
1902
19032. Leave one space and one space only after an end-of-sentence period,
1904 exclamation mark, etc.
1905
19063. For reasons stated below, it is best to follow all period marks with a
1907 carriage return.
1908
1909The reason behind these unusual tips is that g/n/troff have a line breaking
1910algorithm that can be easily upset if you don't follow the rules given above.
1911
1912Unlike TeX, troff fills text line-by-line, not paragraph-by-paragraph and,
1913furthermore, it does not have a concept of glue or stretch, all horizontal and
1914vertical space input will be output as is.
1915
1916Therefore, you should be careful about not using more space between sentences
1917than you intend to have in your final document. For this reason, the common
1918practice is to insert a carriage return immediately after all punctuation
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001919marks. If you want to have "even" text in your final processed output, you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001920need to maintaining regular spacing in the input text. To mark both trailing
1921spaces and two or more spaces after a punctuation as an error, use: >
1922
1923 :let nroff_space_errors = 1
1924
1925Another technique to detect extra spacing and other errors that will interfere
1926with the correct typesetting of your file, is to define an eye-catching
1927highlighting definition for the syntax groups "nroffDefinition" and
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001928"nroffDefSpecial" in your configuration files. For example: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001929
1930 hi def nroffDefinition term=italic cterm=italic gui=reverse
1931 hi def nroffDefSpecial term=italic,bold cterm=italic,bold
1932 \ gui=reverse,bold
1933
1934If you want to navigate preprocessor entries in your source file as easily as
1935with section markers, you can activate the following option in your .vimrc
1936file: >
1937
1938 let b:preprocs_as_sections = 1
1939
Bram Moolenaar69a7cb42004-06-20 12:51:53 +00001940As well, the syntax file adds an extra paragraph marker for the extended
Bram Moolenaar071d4272004-06-13 20:20:40 +00001941paragraph macro (.XP) in the ms package.
1942
1943Finally, there is a |groff.vim| syntax file that can be used for enabling
1944groff syntax highlighting either on a file basis or globally by default.
1945
1946
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001947OCAML *ocaml.vim* *ft-ocaml-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001948
1949The OCaml syntax file handles files having the following prefixes: .ml,
1950.mli, .mll and .mly. By setting the following variable >
1951
1952 :let ocaml_revised = 1
1953
1954you can switch from standard OCaml-syntax to revised syntax as supported
1955by the camlp4 preprocessor. Setting the variable >
1956
1957 :let ocaml_noend_error = 1
1958
1959prevents highlighting of "end" as error, which is useful when sources
1960contain very long structures that Vim does not synchronize anymore.
1961
1962
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001963PAPP *papp.vim* *ft-papp-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001964
1965The PApp syntax file handles .papp files and, to a lesser extend, .pxml
1966and .pxsl files which are all a mixture of perl/xml/html/other using xml
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001967as the top-level file format. By default everything inside phtml or pxml
1968sections is treated as a string with embedded preprocessor commands. If
Bram Moolenaar071d4272004-06-13 20:20:40 +00001969you set the variable: >
1970
1971 :let papp_include_html=1
1972
1973in your startup file it will try to syntax-hilight html code inside phtml
1974sections, but this is relatively slow and much too colourful to be able to
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001975edit sensibly. ;)
Bram Moolenaar071d4272004-06-13 20:20:40 +00001976
1977The newest version of the papp.vim syntax file can usually be found at
1978http://papp.plan9.de.
1979
1980
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001981PASCAL *pascal.vim* *ft-pascal-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001982
1983Files matching "*.p" could be Progress or Pascal. If the automatic detection
1984doesn't work for you, or you don't edit Progress at all, use this in your
1985startup vimrc: >
1986
1987 :let filetype_p = "pascal"
1988
1989The Pascal syntax file has been extended to take into account some extensions
1990provided by Turbo Pascal, Free Pascal Compiler and GNU Pascal Compiler.
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001991Delphi keywords are also supported. By default, Turbo Pascal 7.0 features are
Bram Moolenaar071d4272004-06-13 20:20:40 +00001992enabled. If you prefer to stick with the standard Pascal keywords, add the
1993following line to your startup file: >
1994
1995 :let pascal_traditional=1
1996
1997To switch on Delphi specific constructions (such as one-line comments,
1998keywords, etc): >
1999
2000 :let pascal_delphi=1
2001
2002
2003The option pascal_symbol_operator controls whether symbol operators such as +,
2004*, .., etc. are displayed using the Operator color or not. To colorize symbol
2005operators, add the following line to your startup file: >
2006
2007 :let pascal_symbol_operator=1
2008
2009Some functions are highlighted by default. To switch it off: >
2010
2011 :let pascal_no_functions=1
2012
Bram Moolenaar996343d2010-07-04 22:20:21 +02002013Furthermore, there are specific variables for some compilers. Besides
Bram Moolenaar071d4272004-06-13 20:20:40 +00002014pascal_delphi, there are pascal_gpc and pascal_fpc. Default extensions try to
2015match Turbo Pascal. >
2016
2017 :let pascal_gpc=1
2018
2019or >
2020
2021 :let pascal_fpc=1
2022
2023To ensure that strings are defined on a single line, you can define the
2024pascal_one_line_string variable. >
2025
2026 :let pascal_one_line_string=1
2027
2028If you dislike <Tab> chars, you can set the pascal_no_tabs variable. Tabs
2029will be highlighted as Error. >
2030
2031 :let pascal_no_tabs=1
2032
2033
2034
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002035PERL *perl.vim* *ft-perl-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002036
2037There are a number of possible options to the perl syntax highlighting.
2038

2052enabled it.)
2053
2054If you do not want complex things like '@{${"foo"}}' to be parsed: >
2055
2056 :let perl_no_extended_vars = 1
2057
Bram Moolenaar3fdfa4a2004-10-07 21:02:47 +00002058(In Vim 6.x it was the other way around: "perl_extended_vars" enabled it.)

Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002060The coloring strings can be changed. By default strings and qq friends will be
2061highlighted like the first line. If you set the variable
Bram Moolenaar071d4272004-06-13 20:20:40 +00002062perl_string_as_statement, it will be highlighted as in the second line.
2063
2064 "hello world!"; qq|hello world|;
2065 ^^^^^^^^^^^^^^NN^^^^^^^^^^^^^^^N (unlet perl_string_as_statement)
2066 S^^^^^^^^^^^^SNNSSS^^^^^^^^^^^SN (let perl_string_as_statement)
2067
2068(^ = perlString, S = perlStatement, N = None at all)
2069
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002070The syncing has 3 options. The first two switch off some triggering of
Bram Moolenaar071d4272004-06-13 20:20:40 +00002071synchronization and should only be needed in case it fails to work properly.
2072If while scrolling all of a sudden the whole screen changes color completely
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002073then you should try and switch off one of those. Let me know if you can figure
Bram Moolenaar071d4272004-06-13 20:20:40 +00002074out the line that causes the mistake.

2186- ppwiz_with_html : If the value is 1 (the default), highlight literal
2187 HTML code; if 0, treat HTML code like ordinary text.
2188
2189
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002190PHTML *phtml.vim* *ft-phtml-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002191
2192There are two options for the phtml syntax highlighting.
2193
2194If you like SQL syntax highlighting inside Strings, use this: >
2195
2196 :let phtml_sql_query = 1
2197
2198For syncing, minlines defaults to 100. If you prefer another value, you can
2199set "phtml_minlines" to the value you desire. Example: >
2200
2201 :let phtml_minlines = 200
2202
2203
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002204POSTSCRIPT *postscr.vim* *ft-postscr-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002205
2206There are several options when it comes to highlighting PostScript.
2207
2208First which version of the PostScript language to highlight. There are
2209currently three defined language versions, or levels. Level 1 is the original
2210and base version, and includes all extensions prior to the release of level 2.
2211Level 2 is the most common version around, and includes its own set of
2212extensions prior to the release of level 3. Level 3 is currently the highest
2213level supported. You select which level of the PostScript language you want
2214highlighted by defining the postscr_level variable as follows: >
2215
2216 :let postscr_level=2
2217
2218If this variable is not defined it defaults to 2 (level 2) since this is
2219the most prevalent version currently.
2220
2221Note, not all PS interpreters will support all language features for a
2222particular language level. In particular the %!PS-Adobe-3.0 at the start of
2223PS files does NOT mean the PostScript present is level 3 PostScript!
2224
2225If you are working with Display PostScript, you can include highlighting of
2226Display PS language features by defining the postscr_display variable as
2227follows: >
2228
2229 :let postscr_display=1
2230
2231If you are working with Ghostscript, you can include highlighting of
2232Ghostscript specific language features by defining the variable
2233postscr_ghostscript as follows: >
2234
2235 :let postscr_ghostscript=1
2236
2237PostScript is a large language, with many predefined elements. While it
2238useful to have all these elements highlighted, on slower machines this can
2239cause Vim to slow down. In an attempt to be machine friendly font names and
2240character encodings are not highlighted by default. Unless you are working
2241explicitly with either of these this should be ok. If you want them to be
2242highlighted you should set one or both of the following variables: >
2243
2244 :let postscr_fonts=1
2245 :let postscr_encodings=1
2246
2247There is a stylistic option to the highlighting of and, or, and not. In
2248PostScript the function of these operators depends on the types of their
2249operands - if the operands are booleans then they are the logical operators,
2250if they are integers then they are binary operators. As binary and logical
2251operators can be highlighted differently they have to be highlighted one way
2252or the other. By default they are treated as logical operators. They can be
2253highlighted as binary operators by defining the variable
2254postscr_andornot_binary as follows: >
2255
2256 :let postscr_andornot_binary=1
2257<
2258
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002259 *ptcap.vim* *ft-printcap-syntax*
2260PRINTCAP + TERMCAP *ft-ptcap-syntax* *ft-termcap-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002261
2262This syntax file applies to the printcap and termcap databases.
2263
2264In order for Vim to recognize printcap/termcap files that do not match
2265the patterns *printcap*, or *termcap*, you must put additional patterns
2266appropriate to your system in your |myfiletypefile| file. For these
2267patterns, you must set the variable "b:ptcap_type" to either "print" or
2268"term", and then the 'filetype' option to ptcap.
2269
2270For example, to make Vim identify all files in /etc/termcaps/ as termcap
2271files, add the following: >
2272
2273 :au BufNewFile,BufRead /etc/termcaps/* let b:ptcap_type = "term" |
2274 \ set filetype=ptcap
2275
2276If you notice highlighting errors while scrolling backwards, which
2277are fixed when redrawing with CTRL-L, try setting the "ptcap_minlines"
2278internal variable to a larger number: >
2279
2280 :let ptcap_minlines = 50
2281
2282(The default is 20 lines.)
2283
2284
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002285PROGRESS *progress.vim* *ft-progress-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002286
2287Files matching "*.w" could be Progress or cweb. If the automatic detection
2288doesn't work for you, or you don't edit cweb at all, use this in your
2289startup vimrc: >
2290 :let filetype_w = "progress"
2291The same happens for "*.i", which could be assembly, and "*.p", which could be
2292Pascal. Use this if you don't use assembly and Pascal: >
2293 :let filetype_i = "progress"
2294 :let filetype_p = "progress"
2295
2296
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002297PYTHON *python.vim* *ft-python-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002298
2299There are four options to control Python syntax highlighting.
2300
2301For highlighted numbers: >
2302 :let python_highlight_numbers = 1
2303
2304For highlighted builtin functions: >
2305 :let python_highlight_builtins = 1
2306
2307For highlighted standard exceptions: >
2308 :let python_highlight_exceptions = 1
2309
Bram Moolenaar4a748032010-09-30 21:47:56 +02002310For highlighted trailing whitespace and mix of spaces and tabs: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00002311 :let python_highlight_space_errors = 1
2312
2313If you want all possible Python highlighting (the same as setting the
2314preceding three options): >
2315 :let python_highlight_all = 1
2316
2317
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002318QUAKE *quake.vim* *ft-quake-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002319
2320The Quake syntax definition should work for most any FPS (First Person
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002321Shooter) based on one of the Quake engines. However, the command names vary
Bram Moolenaar071d4272004-06-13 20:20:40 +00002322a bit between the three games (Quake, Quake 2, and Quake 3 Arena) so the
2323syntax definition checks for the existence of three global variables to allow
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002324users to specify what commands are legal in their files. The three variables
Bram Moolenaar071d4272004-06-13 20:20:40 +00002325can be set for the following effects:
2326
2327set to highlight commands only available in Quake: >
2328 :let quake_is_quake1 = 1
2329
2330set to highlight commands only available in Quake 2: >
2331 :let quake_is_quake2 = 1
2332
2333set to highlight commands only available in Quake 3 Arena: >
2334 :let quake_is_quake3 = 1
2335
2336Any combination of these three variables is legal, but might highlight more
2337commands than are actually available to you by the game.
2338
2339
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002340READLINE *readline.vim* *ft-readline-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002341
2342The readline library is primarily used by the BASH shell, which adds quite a
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002343few commands and options to the ones already available. To highlight these
Bram Moolenaar071d4272004-06-13 20:20:40 +00002344items as well you can add the following to your |vimrc| or just type it in the
2345command line before loading a file with the readline syntax: >
2346 let readline_has_bash = 1
2347
2348This will add highlighting for the commands that BASH (version 2.05a and
2349later, and part earlier) adds.
2350
2351
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002352REXX *rexx.vim* *ft-rexx-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002353
2354If you notice highlighting errors while scrolling backwards, which are fixed
2355when redrawing with CTRL-L, try setting the "rexx_minlines" internal variable
2356to a larger number: >
2357 :let rexx_minlines = 50
2358This will make the syntax synchronization start 50 lines before the first
2359displayed line. The default value is 10. The disadvantage of using a larger
2360number is that redrawing can become slow.
2361
2362
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002363RUBY *ruby.vim* *ft-ruby-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002364
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002365There are a number of options to the Ruby syntax highlighting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002366
2367By default, the "end" keyword is colorized according to the opening statement
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002368of the block it closes. While useful, this feature can be expensive; if you
Bram Moolenaar071d4272004-06-13 20:20:40 +00002369experience slow redrawing (or you are on a terminal with poor color support)
2370you may want to turn it off by defining the "ruby_no_expensive" variable: >
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002371
Bram Moolenaar071d4272004-06-13 20:20:40 +00002372 :let ruby_no_expensive = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002373<
Bram Moolenaar071d4272004-06-13 20:20:40 +00002374In this case the same color will be used for all control keywords.
2375
2376If you do want this feature enabled, but notice highlighting errors while
2377scrolling backwards, which are fixed when redrawing with CTRL-L, try setting
2378the "ruby_minlines" variable to a value larger than 50: >
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002379
Bram Moolenaar071d4272004-06-13 20:20:40 +00002380 :let ruby_minlines = 100
Bram Moolenaar25394022007-05-10 19:06:20 +00002381<
Bram Moolenaar071d4272004-06-13 20:20:40 +00002382Ideally, this value should be a number of lines large enough to embrace your
2383largest class or module.
2384
Bram Moolenaar25394022007-05-10 19:06:20 +00002385Highlighting of special identifiers can be disabled by removing the
2386rubyIdentifier highlighting: >
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002387
Bram Moolenaar25394022007-05-10 19:06:20 +00002388 :hi link rubyIdentifier NONE
2389<
Bram Moolenaar071d4272004-06-13 20:20:40 +00002390This will prevent highlighting of special identifiers like "ConstantName",
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002391"$global_var", "@@class_var", "@instance_var", "| block_param |", and
2392":symbol".
Bram Moolenaar071d4272004-06-13 20:20:40 +00002393
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002394Significant methods of Kernel, Module and Object are highlighted by default.
2395This can be disabled by defining "ruby_no_special_methods": >
Bram Moolenaar071d4272004-06-13 20:20:40 +00002396
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002397 :let ruby_no_special_methods = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002398<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002399This will prevent highlighting of important methods such as "require", "attr",
2400"private", "raise" and "proc".
2401
Bram Moolenaar25394022007-05-10 19:06:20 +00002402Ruby operators can be highlighted. This is enabled by defining
2403"ruby_operators": >
2404
2405 :let ruby_operators = 1
2406<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002407Whitespace errors can be highlighted by defining "ruby_space_errors": >
2408
2409 :let ruby_space_errors = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002410<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002411This will highlight trailing whitespace and tabs preceded by a space character
2412as errors. This can be refined by defining "ruby_no_trail_space_error" and
2413"ruby_no_tab_space_error" which will ignore trailing whitespace and tabs after
2414spaces respectively.
2415
2416Folding can be enabled by defining "ruby_fold": >
2417
2418 :let ruby_fold = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002419<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002420This will set the 'foldmethod' option to "syntax" and allow folding of
2421classes, modules, methods, code blocks, heredocs and comments.
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00002422
Bram Moolenaar25394022007-05-10 19:06:20 +00002423Folding of multiline comments can be disabled by defining
2424"ruby_no_comment_fold": >
2425
2426 :let ruby_no_comment_fold = 1

Bram Moolenaarda2303d2005-08-30 21:55:26 +00002429SCHEME *scheme.vim* *ft-scheme-syntax*
Bram Moolenaar21cf8232004-07-16 20:18:37 +00002430
2431By default only R5RS keywords are highlighted and properly indented.
2432
2433MzScheme-specific stuff will be used if b:is_mzscheme or g:is_mzscheme
2434variables are defined.
Bram Moolenaarc9b4b052006-04-30 18:54:39 +00002435
Bram Moolenaar293ee4d2004-12-09 21:34:53 +00002436Also scheme.vim supports keywords of the Chicken Scheme->C compiler. Define
2437b:is_chicken or g:is_chicken, if you need them.
Bram Moolenaar21cf8232004-07-16 20:18:37 +00002438

Bram Moolenaarda2303d2005-08-30 21:55:26 +00002440SDL *sdl.vim* *ft-sdl-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002441
2442The SDL highlighting probably misses a few keywords, but SDL has so many
2443of them it's almost impossibly to cope.
2444
2445The new standard, SDL-2000, specifies that all identifiers are
2446case-sensitive (which was not so before), and that all keywords can be
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002447used either completely lowercase or completely uppercase. To have the
Bram Moolenaar071d4272004-06-13 20:20:40 +00002448highlighting reflect this, you can set the following variable: >
2449 :let sdl_2000=1
2450
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002451This also sets many new keywords. If you want to disable the old
Bram Moolenaar071d4272004-06-13 20:20:40 +00002452keywords, which is probably a good idea, use: >
2453 :let SDL_no_96=1
2454
2455
2456The indentation is probably also incomplete, but right now I am very
2457satisfied with it for my own projects.
2458
2459
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002460SED *sed.vim* *ft-sed-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002461
2462To make tabs stand out from regular blanks (accomplished by using Todo
2463highlighting on the tabs), define "highlight_sedtabs" by putting >
2464
2465 :let highlight_sedtabs = 1
2466
2467in the vimrc file. (This special highlighting only applies for tabs
2468inside search patterns, replacement texts, addresses or text included
2469by an Append/Change/Insert command.) If you enable this option, it is
2470also a good idea to set the tab width to one character; by doing that,
2471you can easily count the number of tabs in a string.
2472
2473Bugs:
2474
2475 The transform command (y) is treated exactly like the substitute
2476 command. This means that, as far as this syntax file is concerned,
2477 transform accepts the same flags as substitute, which is wrong.
2478 (Transform accepts no flags.) I tolerate this bug because the
2479 involved commands need very complex treatment (95 patterns, one for
2480 each plausible pattern delimiter).
2481
2482
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002483SGML *sgml.vim* *ft-sgml-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002484
2485The coloring scheme for tags in the SGML file works as follows.
2486
2487The <> of opening tags are colored differently than the </> of a closing tag.
2488This is on purpose! For opening tags the 'Function' color is used, while for
2489closing tags the 'Type' color is used (See syntax.vim to check how those are
2490defined for you)
2491
2492Known tag names are colored the same way as statements in C. Unknown tag
2493names are not colored which makes it easy to spot errors.
2494
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002495Note that the same is true for argument (or attribute) names. Known attribute
Bram Moolenaar071d4272004-06-13 20:20:40 +00002496names are colored differently than unknown ones.
2497
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002498Some SGML tags are used to change the rendering of text. The following tags
Bram Moolenaar071d4272004-06-13 20:20:40 +00002499are recognized by the sgml.vim syntax coloring file and change the way normal
2500text is shown: <varname> <emphasis> <command> <function> <literal>
2501<replaceable> <ulink> and <link>.
2502
2503If you want to change how such text is rendered, you must redefine the
2504following syntax groups:
2505
2506 - sgmlBold
2507 - sgmlBoldItalic
2508 - sgmlUnderline
2509 - sgmlItalic
2510 - sgmlLink for links
2511
2512To make this redefinition work you must redefine them all and define the
2513following variable in your vimrc (this is due to the order in which the files
2514are read during initialization) >
2515 let sgml_my_rendering=1
2516
2517You can also disable this rendering by adding the following line to your
2518vimrc file: >
2519 let sgml_no_rendering=1

Bram Moolenaar071d4272004-06-13 20:20:40 +00002525
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002526This covers the "normal" Unix (Bourne) sh, bash and the Korn shell.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002527
2528Vim attempts to determine which shell type is in use by specifying that
2529various filenames are of specific types: >
2530
2531 ksh : .kshrc* *.ksh
2532 bash: .bashrc* bashrc bash.bashrc .bash_profile* *.bash
2533<
2534If none of these cases pertain, then the first line of the file is examined
2535(ex. /bin/sh /bin/ksh /bin/bash). If the first line specifies a shelltype,
2536then that shelltype is used. However some files (ex. .profile) are known to
2537be shell files but the type is not apparent. Furthermore, on many systems
Bram Moolenaar7fc904b2006-04-13 20:37:35 +00002538sh is symbolically linked to "bash" (Linux, Windows+cygwin) or "ksh" (Posix).
Bram Moolenaar071d4272004-06-13 20:20:40 +00002539
2540One may specify a global default by instantiating one of the following three
2541variables in your <.vimrc>:
2542
2543 ksh: >
Bram Moolenaar7fc904b2006-04-13 20:37:35 +00002544 let g:is_kornshell = 1
2545< posix: (using this is the same as setting is_kornshell to 1) >
2546 let g:is_posix = 1
Bram Moolenaar071d4272004-06-13 20:20:40 +00002547< bash: >
Bram Moolenaar7fc904b2006-04-13 20:37:35 +00002548 let g:is_bash = 1
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002549< sh: (default) Bourne shell >
Bram Moolenaar7fc904b2006-04-13 20:37:35 +00002550 let g:is_sh = 1
Bram Moolenaar071d4272004-06-13 20:20:40 +00002551
Bram Moolenaar910f66f2006-04-05 20:41:53 +00002552If there's no "#! ..." line, and the user hasn't availed himself/herself of a
2553default sh.vim syntax setting as just shown, then syntax/sh.vim will assume
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002554the Bourne shell syntax. No need to quote RFCs or market penetration
2555statistics in error reports, please -- just select the default version of the
2556sh your system uses in your <.vimrc>.
Bram Moolenaar910f66f2006-04-05 20:41:53 +00002557
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002558The syntax/sh.vim file provides several levels of syntax-based folding: >
2559
2560 let g:sh_fold_enabled= 0 (default, no syntax folding)
2561 let g:sh_fold_enabled= 1 (enable function folding)
2562 let g:sh_fold_enabled= 2 (enable heredoc folding)
2563 let g:sh_fold_enabled= 4 (enable if/do/for folding)
Bram Moolenaar071d4272004-06-13 20:20:40 +00002564>
2565then various syntax items (HereDocuments and function bodies) become
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002566syntax-foldable (see |:syn-fold|). You also may add these together
2567to get multiple types of folding: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00002568
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002569 let g:sh_fold_enabled= 3 (enables function and heredoc folding)
2570
2571If you notice highlighting errors while scrolling backwards which are fixed
2572when one redraws with CTRL-L, try setting the "sh_minlines" internal variable
Bram Moolenaar071d4272004-06-13 20:20:40 +00002573to a larger number. Example: >
2574
2575 let sh_minlines = 500
2576
2577This will make syntax synchronization start 500 lines before the first
2578displayed line. The default value is 200. The disadvantage of using a larger
2579number is that redrawing can become slow.
2580
2581If you don't have much to synchronize on, displaying can be very slow. To
2582reduce this, the "sh_maxlines" internal variable can be set. Example: >
2583
2584 let sh_maxlines = 100
2585<
2586The default is to use the twice sh_minlines. Set it to a smaller number to
2587speed up displaying. The disadvantage is that highlight errors may appear.
2588
2589
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002590SPEEDUP (AspenTech plant simulator) *spup.vim* *ft-spup-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002591
2592The Speedup syntax file has some options:
2593
2594- strict_subsections : If this variable is defined, only keywords for
2595 sections and subsections will be highlighted as statements but not
2596 other keywords (like WITHIN in the OPERATION section).
2597
2598- highlight_types : Definition of this variable causes stream types
2599 like temperature or pressure to be highlighted as Type, not as a
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002600 plain Identifier. Included are the types that are usually found in
Bram Moolenaar071d4272004-06-13 20:20:40 +00002601 the DECLARE section; if you defined own types, you have to include
2602 them in the syntax file.
2603
2604- oneline_comments : this value ranges from 1 to 3 and determines the
2605 highlighting of # style comments.
2606
2607 oneline_comments = 1 : allow normal Speedup code after an even
2608 number of #s.
2609
2610 oneline_comments = 2 : show code starting with the second # as
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002611 error. This is the default setting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002612
2613 oneline_comments = 3 : show the whole line as error if it contains
2614 more than one #.
2615
2616Since especially OPERATION sections tend to become very large due to
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002617PRESETting variables, syncing may be critical. If your computer is
Bram Moolenaar071d4272004-06-13 20:20:40 +00002618fast enough, you can increase minlines and/or maxlines near the end of
2619the syntax file.

Bram Moolenaar1056d982006-03-09 22:37:52 +00002626While there is an ANSI standard for SQL, most database engines add their own
2627custom extensions. Vim currently supports the Oracle and Informix dialects of
2628SQL. Vim assumes "*.sql" files are Oracle SQL by default.

Bram Moolenaar1056d982006-03-09 22:37:52 +00002630Vim currently has SQL support for a variety of different vendors via syntax

Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002644is set. If you want VIM to assume that no backslash quote constructs exist add
Bram Moolenaar071d4272004-06-13 20:20:40 +00002645this line to your .vimrc: >
2646
2647 :let tcsh_backslash_quote = 0
2648
2649If you notice highlighting errors while scrolling backwards, which are fixed

Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01002655This will make the syntax synchronization start 1000 lines before the first
2656displayed line. If you set "tcsh_minlines" to "fromstart", then
2657synchronization is done from the start of the file. The default value for
2658tcsh_minlines is 100. The disadvantage of using a larger number is that
2659redrawing can become slow.

Bram Moolenaar488c6512005-08-11 20:09:58 +00002693The <syntax/tex.vim> highlighting supports TeX, LaTeX, and some AmsTeX. The
2694highlighting supports three primary zones/regions: normal, texZone, and
2695texMathZone. Although considerable effort has been made to have these zones
2696terminate properly, zones delineated by $..$ and $$..$$ cannot be synchronized
2697as there's no difference between start and end patterns. Consequently, a

2726The <tex.vim> supports lexical error checking of various sorts. Thus,
2727although the error checking is ofttimes very useful, it can indicate
2728errors where none actually are. If this proves to be a problem for you,
2729you may put in your <.vimrc> the following statement: >
2730 let tex_no_error=1

Bram Moolenaar488c6512005-08-11 20:09:58 +00002738 call TexNewMathZone(sfx,mathzone,starform)
2739You'll want to provide the new math group with a unique suffix
2740(currently, A-L and V-Z are taken by <syntax/tex.vim> itself).
2741As an example, consider how eqnarray is set up by <syntax/tex.vim>: >
2742 call TexNewMathZone("D","eqnarray",1)
2743You'll need to change "mathzone" to the name of your new math group,
2744and then to the call to it in .vim/after/syntax/tex.vim.
2745The "starform" variable, if true, implies that your new math group
2746has a starred form (ie. eqnarray*).

2752commands available. However, since the *.tex file doesn't have one of the

2757 :set ft=tex
2758

Bram Moolenaar477db062010-07-28 18:17:41 +02002765If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a

2767including various accented characters, Greek characters in MathZones, and
2768superscripts and subscripts in MathZones. Not all characters can be made into
2769superscripts or subscripts; the constraint is due to what utf-8 supports.
2770In fact, only a few characters are supported as subscripts.
2771
2772One way to use this is to have vertically split windows (see |CTRL-W_v|); one

2856The syntax of XF86Config file differs in XFree86 v3.x and v4.x. Both
2857variants are supported. Automatic detection is used, but is far from perfect.
2858You may need to specify the version manually. Set the variable

Bram Moolenaar071d4272004-06-13 20:20:40 +00002888
2889xpm.vim creates its syntax items dynamically based upon the contents of the
2890XPM file. Thus if you make changes e.g. in the color specification strings,
2891you have to source it again e.g. with ":set syn=xpm".
2892
2893To copy a pixel with one of the colors, yank a "pixel" with "yl" and insert it
2894somewhere else with "P".
2895
2896Do you want to draw with the mouse? Try the following: >
2897 :function! GetPixel()
Bram Moolenaar61660ea2006-04-07 21:40:07 +00002898 : let c = getline(".")[col(".") - 1]

2901 : exe "noremap <LeftDrag> <LeftMouse>r".c
2902 :endfunction
2903 :noremap <RightMouse> <LeftMouse>:call GetPixel()<CR>
2904 :set guicursor=n:hor20 " to see the color beneath the cursor
2905This turns the right button into a pipette and the left button into a pen.
2906It will work with XPM files that have one character per pixel only and you
2907must not click outside of the pixel strings, but feel free to improve it.
2908
2909It will look much better with a font in a quadratic cell size, e.g. for X: >

2911
2912==============================================================================
29135. Defining a syntax *:syn-define* *E410*
2914
2915Vim understands three types of syntax items:
2916
Bram Moolenaarce0842a2005-07-18 21:58:11 +000029171. Keyword
Bram Moolenaar071d4272004-06-13 20:20:40 +00002918 It can only contain keyword characters, according to the 'iskeyword'
2919 option. It cannot contain other syntax items. It will only match with a
2920 complete word (there are no keyword characters before or after the match).
2921 The keyword "if" would match in "if(a=b)", but not in "ifdef x", because
2922 "(" is not a keyword character and "d" is.
2923
Bram Moolenaarce0842a2005-07-18 21:58:11 +000029242. Match
Bram Moolenaar071d4272004-06-13 20:20:40 +00002925 This is a match with a single regexp pattern.
2926
Bram Moolenaarce0842a2005-07-18 21:58:11 +000029273. Region
Bram Moolenaar071d4272004-06-13 20:20:40 +00002928 This starts at a match of the "start" regexp pattern and ends with a match
2929 with the "end" regexp pattern. Any other text can appear in between. A
2930 "skip" regexp pattern can be used to avoid matching the "end" pattern.
2931
2932Several syntax ITEMs can be put into one syntax GROUP. For a syntax group
2933you can give highlighting attributes. For example, you could have an item
2934to define a "/* .. */" comment and another one that defines a "// .." comment,
2935and put them both in the "Comment" group. You can then specify that a
2936"Comment" will be in bold font and have a blue color. You are free to make
2937one highlight group for one syntax item, or put all items into one group.
2938This depends on how you want to specify your highlighting attributes. Putting
2939each item in its own group results in having to specify the highlighting
2940for a lot of groups.
2941
2942Note that a syntax group and a highlight group are similar. For a highlight
2943group you will have given highlight attributes. These attributes will be used
2944for the syntax group with the same name.
2945
2946In case more than one item matches at the same position, the one that was
2947defined LAST wins. Thus you can override previously defined syntax items by
2948using an item that matches the same text. But a keyword always goes before a
2949match or region. And a keyword with matching case always goes before a
2950keyword with ignoring case.
2951
2952
2953PRIORITY *:syn-priority*
2954
2955When several syntax items may match, these rules are used:
2956
29571. When multiple Match or Region items start in the same position, the item
2958 defined last has priority.
29592. A Keyword has priority over Match and Region items.
29603. An item that starts in an earlier position has priority over items that
2961 start in later positions.
2962
2963
2964DEFINING CASE *:syn-case* *E390*
2965
Bram Moolenaarce0842a2005-07-18 21:58:11 +00002966:sy[ntax] case [match | ignore]
Bram Moolenaar071d4272004-06-13 20:20:40 +00002967 This defines if the following ":syntax" commands will work with
2968 matching case, when using "match", or with ignoring case, when using
2969 "ignore". Note that any items before this are not affected, and all
2970 items until the next ":syntax case" command are affected.
2971
2972
Bram Moolenaarce0842a2005-07-18 21:58:11 +00002973SPELL CHECKING *:syn-spell*
2974
2975:sy[ntax] spell [toplevel | notoplevel | default]
2976 This defines where spell checking is to be done for text that is not
2977 in a syntax item:
2978
2979 toplevel: Text is spell checked.
2980 notoplevel: Text is not spell checked.
2981 default: When there is a @Spell cluster no spell checking.
2982
2983 For text in syntax items use the @Spell and @NoSpell clusters
2984 |spell-syntax|. When there is no @Spell and no @NoSpell cluster then
2985 spell checking is done for "default" and "toplevel".
2986
2987 To activate spell checking the 'spell' option must be set.
2988
2989
Bram Moolenaar071d4272004-06-13 20:20:40 +00002990DEFINING KEYWORDS *:syn-keyword*
2991
2992:sy[ntax] keyword {group-name} [{options}] {keyword} .. [{options}]
2993
2994 This defines a number of keywords.
2995
2996 {group-name} Is a syntax group name such as "Comment".
2997 [{options}] See |:syn-arguments| below.
2998 {keyword} .. Is a list of keywords which are part of this group.
2999
3000 Example: >
3001 :syntax keyword Type int long char
3002<
3003 The {options} can be given anywhere in the line. They will apply to
3004 all keywords given, also for options that come after a keyword.
3005 These examples do exactly the same: >
3006 :syntax keyword Type contained int long char
3007 :syntax keyword Type int long contained char
3008 :syntax keyword Type int long char contained
Bram Moolenaarfc1421e2006-04-20 22:17:20 +00003009< *E789*
Bram Moolenaar071d4272004-06-13 20:20:40 +00003010 When you have a keyword with an optional tail, like Ex commands in
3011 Vim, you can put the optional characters inside [], to define all the
3012 variations at once: >
3013 :syntax keyword vimCommand ab[breviate] n[ext]
3014<
3015 Don't forget that a keyword can only be recognized if all the
3016 characters are included in the 'iskeyword' option. If one character
3017 isn't, the keyword will never be recognized.
3018 Multi-byte characters can also be used. These do not have to be in
3019 'iskeyword'.
3020
3021 A keyword always has higher priority than a match or region, the
3022 keyword is used if more than one item matches. Keywords do not nest
3023 and a keyword can't contain anything else.
3024
3025 Note that when you have a keyword that is the same as an option (even
3026 one that isn't allowed here), you can not use it. Use a match
3027 instead.
3028
3029 The maximum length of a keyword is 80 characters.
3030
3031 The same keyword can be defined multiple times, when its containment
3032 differs. For example, you can define the keyword once not contained
3033 and use one highlight group, and once contained, and use a different
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00003034 highlight group. Example: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00003035 :syn keyword vimCommand tag
3036 :syn keyword vimSetting contained tag
3037< When finding "tag" outside of any syntax item, the "vimCommand"
3038 highlight group is used. When finding "tag" in a syntax item that
3039 contains "vimSetting", the "vimSetting" group is used.
3040
3041
3042DEFINING MATCHES *:syn-match*
3043
3044:sy[ntax] match {group-name} [{options}] [excludenl] {pattern} [{options}]
3045
3046 This defines one match.
3047
3048 {group-name} A syntax group name such as "Comment".
3049 [{options}] See |:syn-arguments| below.
3050 [excludenl] Don't make a pattern with the end-of-line "$"
3051 extend a containing match or region. Must be
3052 given before the pattern. |:syn-excludenl|
3053 {pattern} The search pattern that defines the match.
3054 See |:syn-pattern| below.
3055 Note that the pattern may match more than one
3056 line, which makes the match depend on where
3057 Vim starts searching for the pattern. You
3058 need to make sure syncing takes care of this.
3059
3060 Example (match a character constant): >
3061 :syntax match Character /'.'/hs=s+1,he=e-1
3062<
3063
3064DEFINING REGIONS *:syn-region* *:syn-start* *:syn-skip* *:syn-end*
3065 *E398* *E399*
3066:sy[ntax] region {group-name} [{options}]
3067 [matchgroup={group-name}]
3068 [keepend]
3069 [extend]
3070 [excludenl]
3071 start={start_pattern} ..
3072 [skip={skip_pattern}]
3073 end={end_pattern} ..
3074 [{options}]
3075
3076 This defines one region. It may span several lines.
3077
3078 {group-name} A syntax group name such as "Comment".
3079 [{options}] See |:syn-arguments| below.
3080 [matchgroup={group-name}] The syntax group to use for the following
3081 start or end pattern matches only. Not used
3082 for the text in between the matched start and
3083 end patterns. Use NONE to reset to not using
3084 a different group for the start or end match.
3085 See |:syn-matchgroup|.
3086 keepend Don't allow contained matches to go past a
3087 match with the end pattern. See
3088 |:syn-keepend|.
3089 extend Override a "keepend" for an item this region
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00003090 is contained in. See |:syn-extend|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003091 excludenl Don't make a pattern with the end-of-line "$"
3092 extend a containing match or item. Only
3093 useful for end patterns. Must be given before
3094 the patterns it applies to. |:syn-excludenl|
3095 start={start_pattern} The search pattern that defines the start of
3096 the region. See |:syn-pattern| below.
3097 skip={skip_pattern} The search pattern that defines text inside
3098 the region where not to look for the end
3099 pattern. See |:syn-pattern| below.
3100 end={end_pattern} The search pattern that defines the end of
3101 the region. See |:syn-pattern| below.
3102
3103 Example: >
3104 :syntax region String start=+"+ skip=+\\"+ end=+"+
3105<
3106 The start/skip/end patterns and the options can be given in any order.
3107 There can be zero or one skip pattern. There must be one or more
3108 start and end patterns. This means that you can omit the skip
3109 pattern, but you must give at least one start and one end pattern. It
3110 is allowed to have white space before and after the equal sign
3111 (although it mostly looks better without white space).
3112
3113 When more than one start pattern is given, a match with one of these
3114 is sufficient. This means there is an OR relation between the start
3115 patterns. The last one that matches is used. The same is true for
3116 the end patterns.
3117
3118 The search for the end pattern starts right after the start pattern.
3119 Offsets are not used for this. This implies that the match for the
3120 end pattern will never overlap with the start pattern.
3121
3122 The skip and end pattern can match across line breaks, but since the
3123 search for the pattern can start in any line it often does not do what
3124 you want. The skip pattern doesn't avoid a match of an end pattern in
3125 the next line. Use single-line patterns to avoid trouble.
3126
3127 Note: The decision to start a region is only based on a matching start
3128 pattern. There is no check for a matching end pattern. This does NOT
3129 work: >
3130 :syn region First start="(" end=":"
3131 :syn region Second start="(" end=";"
3132< The Second always matches before the First (last defined pattern has
3133 higher priority). The Second region then continues until the next
3134 ';', no matter if there is a ':' before it. Using a match does work: >
3135 :syn match First "(\_.\{-}:"
3136 :syn match Second "(\_.\{-};"
3137< This pattern matches any character or line break with "\_." and
3138 repeats that with "\{-}" (repeat as few as possible).
3139
3140 *:syn-keepend*
3141 By default, a contained match can obscure a match for the end pattern.
3142 This is useful for nesting. For example, a region that starts with
3143 "{" and ends with "}", can contain another region. An encountered "}"
3144 will then end the contained region, but not the outer region:
3145 { starts outer "{}" region
3146 { starts contained "{}" region
3147 } ends contained "{}" region
3148 } ends outer "{} region
3149 If you don't want this, the "keepend" argument will make the matching
3150 of an end pattern of the outer region also end any contained item.
3151 This makes it impossible to nest the same region, but allows for
3152 contained items to highlight parts of the end pattern, without causing
3153 that to skip the match with the end pattern. Example: >
3154 :syn match vimComment +"[^"]\+$+
3155 :syn region vimCommand start="set" end="$" contains=vimComment keepend
3156< The "keepend" makes the vimCommand always end at the end of the line,
3157 even though the contained vimComment includes a match with the <EOL>.
3158
3159 When "keepend" is not used, a match with an end pattern is retried
3160 after each contained match. When "keepend" is included, the first
3161 encountered match with an end pattern is used, truncating any
3162 contained matches.
3163 *:syn-extend*
3164 The "keepend" behavior can be changed by using the "extend" argument.
3165 When an item with "extend" is contained in an item that uses
3166 "keepend", the "keepend" is ignored and the containing region will be
3167 extended.
3168 This can be used to have some contained items extend a region while
3169 others don't. Example: >
3170
3171 :syn region htmlRef start=+<a>+ end=+</a>+ keepend contains=htmlItem,htmlScript
3172 :syn match htmlItem +<[^>]*>+ contained
3173 :syn region htmlScript start=+<script+ end=+</script[^>]*>+ contained extend
3174
3175< Here the htmlItem item does not make the htmlRef item continue
3176 further, it is only used to highlight the <> items. The htmlScript
3177 item does extend the htmlRef item.
3178
3179 Another example: >
3180 :syn region xmlFold start="<a>" end="</a>" fold transparent keepend extend
3181< This defines a region with "keepend", so that its end cannot be
3182 changed by contained items, like when the "</a>" is matched to
3183 highlight it differently. But when the xmlFold region is nested (it
3184 includes itself), the "extend" applies, so that the "</a>" of a nested
3185 region only ends that region, and not the one it is contained in.
3186
3187 *:syn-excludenl*
3188 When a pattern for a match or end pattern of a region includes a '$'
3189 to match the end-of-line, it will make a region item that it is
3190 contained in continue on the next line. For example, a match with
3191 "\\$" (backslash at the end of the line) can make a region continue
3192 that would normally stop at the end of the line. This is the default
3193 behavior. If this is not wanted, there are two ways to avoid it:
3194 1. Use "keepend" for the containing item. This will keep all
3195 contained matches from extending the match or region. It can be
3196 used when all contained items must not extend the containing item.
3197 2. Use "excludenl" in the contained item. This will keep that match
3198 from extending the containing match or region. It can be used if
3199 only some contained items must not extend the containing item.
3200 "excludenl" must be given before the pattern it applies to.
3201
3202 *:syn-matchgroup*
3203 "matchgroup" can be used to highlight the start and/or end pattern
3204 differently than the body of the region. Example: >
3205 :syntax region String matchgroup=Quote start=+"+ skip=+\\"+ end=+"+
3206< This will highlight the quotes with the "Quote" group, and the text in
3207 between with the "String" group.
3208 The "matchgroup" is used for all start and end patterns that follow,
3209 until the next "matchgroup". Use "matchgroup=NONE" to go back to not
3210 using a matchgroup.
3211
3212 In a start or end pattern that is highlighted with "matchgroup" the
3213 contained items of the region are not used. This can be used to avoid
3214 that a contained item matches in the start or end pattern match. When
3215 using "transparent", this does not apply to a start or end pattern
3216 match that is highlighted with "matchgroup".
3217
3218 Here is an example, which highlights three levels of parentheses in
3219 different colors: >
3220 :sy region par1 matchgroup=par1 start=/(/ end=/)/ contains=par2

32286. :syntax arguments *:syn-arguments*
3229
3230The :syntax commands that define syntax items take a number of arguments.
3231The common ones are explained here. The arguments may be given in any order
3232and may be mixed with patterns.
3233
3234Not all commands accept all arguments. This table shows which arguments
3235can not be used for all commands:
Bram Moolenaar09092152010-08-08 16:38:42 +02003236 *E395*
Bram Moolenaar860cae12010-06-05 23:22:07 +02003237 contains oneline fold display extend concealends~
3238:syntax keyword - - - - - -
3239:syntax match yes - yes yes yes -
3240:syntax region yes yes yes yes yes yes
Bram Moolenaar071d4272004-06-13 20:20:40 +00003241
3242These arguments can be used for all three commands:
Bram Moolenaar860cae12010-06-05 23:22:07 +02003243 conceal
3244 cchar
Bram Moolenaar071d4272004-06-13 20:20:40 +00003245 contained
3246 containedin
3247 nextgroup
3248 transparent
3249 skipwhite
3250 skipnl
3251 skipempty
3252
Bram Moolenaar860cae12010-06-05 23:22:07 +02003253conceal *conceal* *:syn-conceal*
3254
3255When the "conceal" argument is given, the item is marked as concealable.
Bram Moolenaar370df582010-06-22 05:16:38 +02003256Whether or not it is actually concealed depends on the value of the
Bram Moolenaarf5963f72010-07-23 22:10:27 +02003257'conceallevel' option. The 'concealcursor' option is used to decide whether
3258concealable items in the current line are displayed unconcealed to be able to
3259edit the line.
Bram Moolenaar860cae12010-06-05 23:22:07 +02003260
3261concealends *:syn-concealends*
3262
3263When the "concealends" argument is given, the start and end matches of
3264the region, but not the contents of the region, are marked as concealable.
3265Whether or not they are actually concealed depends on the setting on the
3266'conceallevel' option. The ends of a region can only be concealed separately
3267in this way when they have their own highlighting via "matchgroup"
3268
3269cchar *:syn-cchar*
Bram Moolenaard58e9292011-02-09 17:07:58 +01003270 *E844*
Bram Moolenaar860cae12010-06-05 23:22:07 +02003271The "cchar" argument defines the character shown in place of the item
3272when it is concealed (setting "cchar" only makes sense when the conceal
3273argument is given.) If "cchar" is not set then the default conceal
Bram Moolenaard58e9292011-02-09 17:07:58 +01003274character defined in the 'listchars' option is used. The character cannot be
3275a control character such as Tab. Example: >
Bram Moolenaar860cae12010-06-05 23:22:07 +02003276 :syntax match Entity "&amp;" conceal cchar=&
Bram Moolenaar9028b102010-07-11 16:58:51 +02003277See |hl-Conceal| for highlighting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003278
3279contained *:syn-contained*
3280
3281When the "contained" argument is given, this item will not be recognized at
3282the top level, but only when it is mentioned in the "contains" field of
3283another match. Example: >
3284 :syntax keyword Todo TODO contained
3285 :syntax match Comment "//.*" contains=Todo
3286
3287
3288display *:syn-display*
3289
3290If the "display" argument is given, this item will be skipped when the
3291detected highlighting will not be displayed. This will speed up highlighting,
3292by skipping this item when only finding the syntax state for the text that is
3293to be displayed.
3294
3295Generally, you can use "display" for match and region items that meet these
3296conditions:
3297- The item does not continue past the end of a line. Example for C: A region
3298 for a "/*" comment can't contain "display", because it continues on the next
3299 line.
3300- The item does not contain items that continue past the end of the line or
3301 make it continue on the next line.
3302- The item does not change the size of any item it is contained in. Example
3303 for C: A match with "\\$" in a preprocessor match can't have "display",
3304 because it may make that preprocessor match shorter.
3305- The item does not allow other items to match that didn't match otherwise,
3306 and that item may extend the match too far. Example for C: A match for a
3307 "//" comment can't use "display", because a "/*" inside that comment would
3308 match then and start a comment which extends past the end of the line.
3309
3310Examples, for the C language, where "display" can be used:
3311- match with a number
3312- match with a label
3313
3314
3315transparent *:syn-transparent*
3316
3317If the "transparent" argument is given, this item will not be highlighted
3318itself, but will take the highlighting of the item it is contained in. This
3319is useful for syntax items that don't need any highlighting but are used
3320only to skip over a part of the text.
3321
3322The "contains=" argument is also inherited from the item it is contained in,
3323unless a "contains" argument is given for the transparent item itself. To
3324avoid that unwanted items are contained, use "contains=NONE". Example, which
3325highlights words in strings, but makes an exception for "vim": >
3326 :syn match myString /'[^']*'/ contains=myWord,myVim
3327 :syn match myWord /\<[a-z]*\>/ contained
3328 :syn match myVim /\<vim\>/ transparent contained contains=NONE
3329 :hi link myString String
3330 :hi link myWord Comment
3331Since the "myVim" match comes after "myWord" it is the preferred match (last
3332match in the same position overrules an earlier one). The "transparent"
3333argument makes the "myVim" match use the same highlighting as "myString". But
3334it does not contain anything. If the "contains=NONE" argument would be left
3335out, then "myVim" would use the contains argument from myString and allow
3336"myWord" to be contained, which will be highlighted as a Constant. This
3337happens because a contained match doesn't match inside itself in the same
3338position, thus the "myVim" match doesn't overrule the "myWord" match here.
3339
3340When you look at the colored text, it is like looking at layers of contained
3341items. The contained item is on top of the item it is contained in, thus you
3342see the contained item. When a contained item is transparent, you can look
3343through, thus you see the item it is contained in. In a picture:
3344
3345 look from here
3346
3347 | | | | | |
3348 V V V V V V
3349
3350 xxxx yyy more contained items
3351 .................... contained item (transparent)
3352 ============================= first item
3353
3354The 'x', 'y' and '=' represent a highlighted syntax item. The '.' represent a
3355transparent group.
3356
3357What you see is:
3358
3359 =======xxxx=======yyy========
3360
3361Thus you look through the transparent "....".
3362
3363
3364oneline *:syn-oneline*
3365
3366The "oneline" argument indicates that the region does not cross a line
3367boundary. It must match completely in the current line. However, when the
3368region has a contained item that does cross a line boundary, it continues on
3369the next line anyway. A contained item can be used to recognize a line
3370continuation pattern. But the "end" pattern must still match in the first
3371line, otherwise the region doesn't even start.
3372
3373When the start pattern includes a "\n" to match an end-of-line, the end
3374pattern must be found in the same line as where the start pattern ends. The
3375end pattern may also include an end-of-line. Thus the "oneline" argument
3376means that the end of the start pattern and the start of the end pattern must
3377be within one line. This can't be changed by a skip pattern that matches a
3378line break.
3379
3380
3381fold *:syn-fold*
3382
Bram Moolenaar8c8de832008-06-24 22:58:06 +00003383The "fold" argument makes the fold level increase by one for this item.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003384Example: >
3385 :syn region myFold start="{" end="}" transparent fold
3386 :syn sync fromstart
3387 :set foldmethod=syntax
3388This will make each {} block form one fold.
3389
3390The fold will start on the line where the item starts, and end where the item
3391ends. If the start and end are within the same line, there is no fold.
3392The 'foldnestmax' option limits the nesting of syntax folds.
3393{not available when Vim was compiled without |+folding| feature}
3394
3395
3396 *:syn-contains* *E405* *E406* *E407* *E408* *E409*
3397contains={groupname},..
3398
3399The "contains" argument is followed by a list of syntax group names. These
3400groups will be allowed to begin inside the item (they may extend past the
3401containing group's end). This allows for recursive nesting of matches and
3402regions. If there is no "contains" argument, no groups will be contained in
3403this item. The group names do not need to be defined before they can be used
3404here.
3405
3406contains=ALL
3407 If the only item in the contains list is "ALL", then all
3408 groups will be accepted inside the item.
3409
3410contains=ALLBUT,{group-name},..
3411 If the first item in the contains list is "ALLBUT", then all
3412 groups will be accepted inside the item, except the ones that
3413 are listed. Example: >
3414 :syntax region Block start="{" end="}" ... contains=ALLBUT,Function
3415
3416contains=TOP
3417 If the first item in the contains list is "TOP", then all
3418 groups will be accepted that don't have the "contained"
3419 argument.
3420contains=TOP,{group-name},..
3421 Like "TOP", but excluding the groups that are listed.
3422
3423contains=CONTAINED
3424 If the first item in the contains list is "CONTAINED", then
3425 all groups will be accepted that have the "contained"
3426 argument.
3427contains=CONTAINED,{group-name},..
3428 Like "CONTAINED", but excluding the groups that are
3429 listed.
3430
3431
3432The {group-name} in the "contains" list can be a pattern. All group names
3433that match the pattern will be included (or excluded, if "ALLBUT" is used).
3434The pattern cannot contain white space or a ','. Example: >
3435 ... contains=Comment.*,Keyw[0-3]
3436The matching will be done at moment the syntax command is executed. Groups
3437that are defined later will not be matched. Also, if the current syntax
3438command defines a new group, it is not matched. Be careful: When putting
3439syntax commands in a file you can't rely on groups NOT being defined, because
3440the file may have been sourced before, and ":syn clear" doesn't remove the
3441group names.
3442
3443The contained groups will also match in the start and end patterns of a
3444region. If this is not wanted, the "matchgroup" argument can be used
3445|:syn-matchgroup|. The "ms=" and "me=" offsets can be used to change the
3446region where contained items do match. Note that this may also limit the
3447area that is highlighted
3448
3449
3450containedin={groupname}... *:syn-containedin*
3451
3452The "containedin" argument is followed by a list of syntax group names. The
3453item will be allowed to begin inside these groups. This works as if the
3454containing item has a "contains=" argument that includes this item.
3455
3456The {groupname}... can be used just like for "contains", as explained above.
3457
3458This is useful when adding a syntax item afterwards. An item can be told to
3459be included inside an already existing item, without changing the definition
3460of that item. For example, to highlight a word in a C comment after loading
3461the C syntax: >
3462 :syn keyword myword HELP containedin=cComment contained
3463Note that "contained" is also used, to avoid that the item matches at the top
3464level.
3465
3466Matches for "containedin" are added to the other places where the item can
3467appear. A "contains" argument may also be added as usual. Don't forget that
3468keywords never contain another item, thus adding them to "containedin" won't
3469work.
3470
3471
3472nextgroup={groupname},.. *:syn-nextgroup*
3473
3474The "nextgroup" argument is followed by a list of syntax group names,
3475separated by commas (just like with "contains", so you can also use patterns).
3476
3477If the "nextgroup" argument is given, the mentioned syntax groups will be
3478tried for a match, after the match or region ends. If none of the groups have
3479a match, highlighting continues normally. If there is a match, this group
3480will be used, even when it is not mentioned in the "contains" field of the
3481current group. This is like giving the mentioned group priority over all
3482other groups. Example: >
3483 :syntax match ccFoobar "Foo.\{-}Bar" contains=ccFoo
3484 :syntax match ccFoo "Foo" contained nextgroup=ccFiller
3485 :syntax region ccFiller start="." matchgroup=ccBar end="Bar" contained
3486
3487This will highlight "Foo" and "Bar" differently, and only when there is a
3488"Bar" after "Foo". In the text line below, "f" shows where ccFoo is used for
3489highlighting, and "bbb" where ccBar is used. >
3490
3491 Foo asdfasd Bar asdf Foo asdf Bar asdf
3492 fff bbb fff bbb
3493
3494Note the use of ".\{-}" to skip as little as possible until the next Bar.
3495when ".*" would be used, the "asdf" in between "Bar" and "Foo" would be
3496highlighted according to the "ccFoobar" group, because the ccFooBar match
3497would include the first "Foo" and the last "Bar" in the line (see |pattern|).
3498
3499
3500skipwhite *:syn-skipwhite*
3501skipnl *:syn-skipnl*
3502skipempty *:syn-skipempty*
3503
3504These arguments are only used in combination with "nextgroup". They can be
3505used to allow the next group to match after skipping some text:
Bram Moolenaardd2a0d82007-05-12 15:07:00 +00003506 skipwhite skip over space and tab characters
Bram Moolenaar071d4272004-06-13 20:20:40 +00003507 skipnl skip over the end of a line
3508 skipempty skip over empty lines (implies a "skipnl")
3509
3510When "skipwhite" is present, the white space is only skipped if there is no
3511next group that matches the white space.
3512
3513When "skipnl" is present, the match with nextgroup may be found in the next
3514line. This only happens when the current item ends at the end of the current
3515line! When "skipnl" is not present, the nextgroup will only be found after
3516the current item in the same line.
3517
3518When skipping text while looking for a next group, the matches for other
3519groups are ignored. Only when no next group matches, other items are tried
3520for a match again. This means that matching a next group and skipping white
3521space and <EOL>s has a higher priority than other items.
3522
3523Example: >
3524 :syn match ifstart "\<if.*" nextgroup=ifline skipwhite skipempty
3525 :syn match ifline "[^ \t].*" nextgroup=ifline skipwhite skipempty contained
3526 :syn match ifline "endif" contained
3527Note that the "[^ \t].*" match matches all non-white text. Thus it would also
3528match "endif". Therefore the "endif" match is put last, so that it takes
3529precedence.
3530Note that this example doesn't work for nested "if"s. You need to add
3531"contains" arguments to make that work (omitted for simplicity of the
3532example).
3533
Bram Moolenaar860cae12010-06-05 23:22:07 +02003534IMPLICIT CONCEAL *:syn-conceal-implicit*
3535
3536:sy[ntax] conceal [on|off]
3537 This defines if the following ":syntax" commands will define keywords,
3538 matches or regions with the "conceal" flag set. After ":syn conceal
3539 on", all subsequent ":syn keyword", ":syn match" or ":syn region"
3540 defined will have the "conceal" flag set implicitly. ":syn conceal
3541 off" returns to the normal state where the "conceal" flag must be
3542 given explicitly.
3543
Bram Moolenaar071d4272004-06-13 20:20:40 +00003544==============================================================================
35457. Syntax patterns *:syn-pattern* *E401* *E402*
3546
3547In the syntax commands, a pattern must be surrounded by two identical
3548characters. This is like it works for the ":s" command. The most common to
3549use is the double quote. But if the pattern contains a double quote, you can
3550use another character that is not used in the pattern. Examples: >
3551 :syntax region Comment start="/\*" end="\*/"
3552 :syntax region String start=+"+ end=+"+ skip=+\\"+
3553
3554See |pattern| for the explanation of what a pattern is. Syntax patterns are
Bram Moolenaar8c8de832008-06-24 22:58:06 +00003555always interpreted like the 'magic' option is set, no matter what the actual
Bram Moolenaar071d4272004-06-13 20:20:40 +00003556value of 'magic' is. And the patterns are interpreted like the 'l' flag is
3557not included in 'cpoptions'. This was done to make syntax files portable and
3558independent of 'compatible' and 'magic' settings.
3559
3560Try to avoid patterns that can match an empty string, such as "[a-z]*".
3561This slows down the highlighting a lot, because it matches everywhere.
3562
3563 *:syn-pattern-offset*
3564The pattern can be followed by a character offset. This can be used to
3565change the highlighted part, and to change the text area included in the
3566match or region (which only matters when trying to match other items). Both
3567are relative to the matched pattern. The character offset for a skip
3568pattern can be used to tell where to continue looking for an end pattern.
3569
3570The offset takes the form of "{what}={offset}"
3571The {what} can be one of seven strings:
3572
3573ms Match Start offset for the start of the matched text
3574me Match End offset for the end of the matched text
3575hs Highlight Start offset for where the highlighting starts
3576he Highlight End offset for where the highlighting ends
3577rs Region Start offset for where the body of a region starts
3578re Region End offset for where the body of a region ends
3579lc Leading Context offset past "leading context" of pattern
3580
3581The {offset} can be:
3582
3583s start of the matched pattern
3584s+{nr} start of the matched pattern plus {nr} chars to the right
3585s-{nr} start of the matched pattern plus {nr} chars to the left
3586e end of the matched pattern
3587e+{nr} end of the matched pattern plus {nr} chars to the right
3588e-{nr} end of the matched pattern plus {nr} chars to the left
3589{nr} (for "lc" only): start matching {nr} chars to the left
3590
3591Examples: "ms=s+1", "hs=e-2", "lc=3".
3592
3593Although all offsets are accepted after any pattern, they are not always
3594meaningful. This table shows which offsets are actually used:
3595
3596 ms me hs he rs re lc ~
3597match item yes yes yes yes - - yes
3598region item start yes - yes - yes - yes
3599region item skip - yes - - - - yes
3600region item end - yes - yes - yes yes
3601
3602Offsets can be concatenated, with a ',' in between. Example: >
3603 :syn match String /"[^"]*"/hs=s+1,he=e-1
3604<
3605 some "string" text
3606 ^^^^^^ highlighted
3607
3608Notes:
3609- There must be no white space between the pattern and the character
3610 offset(s).
3611- The highlighted area will never be outside of the matched text.
3612- A negative offset for an end pattern may not always work, because the end
3613 pattern may be detected when the highlighting should already have stopped.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003614- Before Vim 7.2 the offsets were counted in bytes instead of characters.
3615 This didn't work well for multi-byte characters, so it was changed with the
3616 Vim 7.2 release.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003617- The start of a match cannot be in a line other than where the pattern
3618 matched. This doesn't work: "a\nb"ms=e. You can make the highlighting
3619 start in another line, this does work: "a\nb"hs=e.
3620
3621Example (match a comment but don't highlight the /* and */): >
3622 :syntax region Comment start="/\*"hs=e+1 end="\*/"he=s-1
3623<
3624 /* this is a comment */
3625 ^^^^^^^^^^^^^^^^^^^ highlighted
3626
3627A more complicated Example: >
3628 :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
3629<
3630 abcfoostringbarabc
3631 mmmmmmmmmmm match
Bram Moolenaar4770d092006-01-12 23:22:24 +00003632 sssrrreee highlight start/region/end ("Foo", "Exa" and "Bar")
Bram Moolenaar071d4272004-06-13 20:20:40 +00003633
3634Leading context *:syn-lc* *:syn-leading* *:syn-context*
3635
3636Note: This is an obsolete feature, only included for backwards compatibility
3637with previous Vim versions. It's now recommended to use the |/\@<=| construct
3638in the pattern.
3639
3640The "lc" offset specifies leading context -- a part of the pattern that must
3641be present, but is not considered part of the match. An offset of "lc=n" will
3642cause Vim to step back n columns before attempting the pattern match, allowing
3643characters which have already been matched in previous patterns to also be
3644used as leading context for this match. This can be used, for instance, to
3645specify that an "escaping" character must not precede the match: >
3646
3647 :syn match ZNoBackslash "[^\\]z"ms=s+1
3648 :syn match WNoBackslash "[^\\]w"lc=1
3649 :syn match Underline "_\+"
3650<
3651 ___zzzz ___wwww
3652 ^^^ ^^^ matches Underline
3653 ^ ^ matches ZNoBackslash
3654 ^^^^ matches WNoBackslash
3655
3656The "ms" offset is automatically set to the same value as the "lc" offset,
3657unless you set "ms" explicitly.
3658
3659
3660Multi-line patterns *:syn-multi-line*
3661
3662The patterns can include "\n" to match an end-of-line. Mostly this works as
3663expected, but there are a few exceptions.
3664
3665When using a start pattern with an offset, the start of the match is not
3666allowed to start in a following line. The highlighting can start in a
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003667following line though. Using the "\zs" item also requires that the start of
3668the match doesn't move to another line.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003669
3670The skip pattern can include the "\n", but the search for an end pattern will
3671continue in the first character of the next line, also when that character is
3672matched by the skip pattern. This is because redrawing may start in any line
3673halfway a region and there is no check if the skip pattern started in a
3674previous line. For example, if the skip pattern is "a\nb" and an end pattern
3675is "b", the end pattern does match in the second line of this: >
3676 x x a
3677 b x x
3678Generally this means that the skip pattern should not match any characters
3679after the "\n".
3680
3681
3682External matches *:syn-ext-match*
3683
3684These extra regular expression items are available in region patterns:
3685
3686 */\z(* */\z(\)* *E50* *E52*
3687 \z(\) Marks the sub-expression as "external", meaning that it is can
3688 be accessed from another pattern match. Currently only usable
3689 in defining a syntax region start pattern.
3690
3691 */\z1* */\z2* */\z3* */\z4* */\z5*
3692 \z1 ... \z9 */\z6* */\z7* */\z8* */\z9* *E66* *E67*
3693 Matches the same string that was matched by the corresponding
3694 sub-expression in a previous start pattern match.
3695
3696Sometimes the start and end patterns of a region need to share a common
3697sub-expression. A common example is the "here" document in Perl and many Unix
3698shells. This effect can be achieved with the "\z" special regular expression
3699items, which marks a sub-expression as "external", in the sense that it can be
3700referenced from outside the pattern in which it is defined. The here-document
3701example, for instance, can be done like this: >
3702 :syn region hereDoc start="<<\z(\I\i*\)" end="^\z1$"
3703
3704As can be seen here, the \z actually does double duty. In the start pattern,
3705it marks the "\(\I\i*\)" sub-expression as external; in the end pattern, it
3706changes the \1 back-reference into an external reference referring to the
3707first external sub-expression in the start pattern. External references can
3708also be used in skip patterns: >
3709 :syn region foo start="start \(\I\i*\)" skip="not end \z1" end="end \z1"
3710
3711Note that normal and external sub-expressions are completely orthogonal and
3712indexed separately; for instance, if the pattern "\z(..\)\(..\)" is applied
3713to the string "aabb", then \1 will refer to "bb" and \z1 will refer to "aa".
3714Note also that external sub-expressions cannot be accessed as back-references
3715within the same pattern like normal sub-expressions. If you want to use one
3716sub-expression as both a normal and an external sub-expression, you can nest
3717the two, as in "\(\z(...\)\)".
3718
3719Note that only matches within a single line can be used. Multi-line matches
3720cannot be referred to.
3721
3722==============================================================================
37238. Syntax clusters *:syn-cluster* *E400*
3724
3725:sy[ntax] cluster {cluster-name} [contains={group-name}..]
3726 [add={group-name}..]
3727 [remove={group-name}..]
3728
3729This command allows you to cluster a list of syntax groups together under a
3730single name.
3731
3732 contains={group-name}..
3733 The cluster is set to the specified list of groups.
3734 add={group-name}..
3735 The specified groups are added to the cluster.
3736 remove={group-name}..
3737 The specified groups are removed from the cluster.
3738
Bram Moolenaar8c8de832008-06-24 22:58:06 +00003739A cluster so defined may be referred to in a contains=.., containedin=..,
3740nextgroup=.., add=.. or remove=.. list with a "@" prefix. You can also use
3741this notation to implicitly declare a cluster before specifying its contents.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003742
3743Example: >
3744 :syntax match Thing "# [^#]\+ #" contains=@ThingMembers
3745 :syntax cluster ThingMembers contains=ThingMember1,ThingMember2
3746
3747As the previous example suggests, modifications to a cluster are effectively
3748retroactive; the membership of the cluster is checked at the last minute, so
3749to speak: >
3750 :syntax keyword A aaa
3751 :syntax keyword B bbb
3752 :syntax cluster AandB contains=A
3753 :syntax match Stuff "( aaa bbb )" contains=@AandB
3754 :syntax cluster AandB add=B " now both keywords are matched in Stuff
3755
3756This also has implications for nested clusters: >
3757 :syntax keyword A aaa
3758 :syntax keyword B bbb
3759 :syntax cluster SmallGroup contains=B
3760 :syntax cluster BigGroup contains=A,@SmallGroup
3761 :syntax match Stuff "( aaa bbb )" contains=@BigGroup
3762 :syntax cluster BigGroup remove=B " no effect, since B isn't in BigGroup
3763 :syntax cluster SmallGroup remove=B " now bbb isn't matched within Stuff
3764
3765==============================================================================
37669. Including syntax files *:syn-include* *E397*
3767
3768It is often useful for one language's syntax file to include a syntax file for
3769a related language. Depending on the exact relationship, this can be done in
3770two different ways:
3771
3772 - If top-level syntax items in the included syntax file are to be
3773 allowed at the top level in the including syntax, you can simply use
3774 the |:runtime| command: >
3775
3776 " In cpp.vim:
3777 :runtime! syntax/c.vim
3778 :unlet b:current_syntax
3779
3780< - If top-level syntax items in the included syntax file are to be
3781 contained within a region in the including syntax, you can use the
3782 ":syntax include" command:
3783
3784:sy[ntax] include [@{grouplist-name}] {file-name}
3785
3786 All syntax items declared in the included file will have the
3787 "contained" flag added. In addition, if a group list is specified,
3788 all top-level syntax items in the included file will be added to
3789 that list. >
3790
3791 " In perl.vim:
3792 :syntax include @Pod <sfile>:p:h/pod.vim
3793 :syntax region perlPOD start="^=head" end="^=cut" contains=@Pod
3794<
3795 When {file-name} is an absolute path (starts with "/", "c:", "$VAR"
3796 or "<sfile>") that file is sourced. When it is a relative path
3797 (e.g., "syntax/pod.vim") the file is searched for in 'runtimepath'.
3798 All matching files are loaded. Using a relative path is
3799 recommended, because it allows a user to replace the included file
3800 with his own version, without replacing the file that does the ":syn
3801 include".
3802
3803==============================================================================
380410. Synchronizing *:syn-sync* *E403* *E404*
3805
3806Vim wants to be able to start redrawing in any position in the document. To
3807make this possible it needs to know the syntax state at the position where
3808redrawing starts.
3809
3810:sy[ntax] sync [ccomment [group-name] | minlines={N} | ...]
3811
3812There are four ways to synchronize:
38131. Always parse from the start of the file.
3814 |:syn-sync-first|
38152. Based on C-style comments. Vim understands how C-comments work and can
3816 figure out if the current line starts inside or outside a comment.
3817 |:syn-sync-second|
38183. Jumping back a certain number of lines and start parsing there.
3819 |:syn-sync-third|
38204. Searching backwards in the text for a pattern to sync on.
3821 |:syn-sync-fourth|
3822
3823 *:syn-sync-maxlines* *:syn-sync-minlines*
3824For the last three methods, the line range where the parsing can start is
3825limited by "minlines" and "maxlines".
3826
3827If the "minlines={N}" argument is given, the parsing always starts at least
3828that many lines backwards. This can be used if the parsing may take a few
3829lines before it's correct, or when it's not possible to use syncing.
3830
3831If the "maxlines={N}" argument is given, the number of lines that are searched
3832for a comment or syncing pattern is restricted to N lines backwards (after
3833adding "minlines"). This is useful if you have few things to sync on and a
3834slow machine. Example: >
3835 :syntax sync ccomment maxlines=500
3836<
3837 *:syn-sync-linebreaks*
3838When using a pattern that matches multiple lines, a change in one line may
3839cause a pattern to no longer match in a previous line. This means has to
3840start above where the change was made. How many lines can be specified with
3841the "linebreaks" argument. For example, when a pattern may include one line
3842break use this: >
3843 :syntax sync linebreaks=1
3844The result is that redrawing always starts at least one line before where a
3845change was made. The default value for "linebreaks" is zero. Usually the
3846value for "minlines" is bigger than "linebreaks".
3847
3848
3849First syncing method: *:syn-sync-first*
3850>
3851 :syntax sync fromstart
3852
3853The file will be parsed from the start. This makes syntax highlighting
3854accurate, but can be slow for long files. Vim caches previously parsed text,
3855so that it's only slow when parsing the text for the first time. However,
3856when making changes some part of the next needs to be parsed again (worst
3857case: to the end of the file).
3858
3859Using "fromstart" is equivalent to using "minlines" with a very large number.
3860
3861
3862Second syncing method: *:syn-sync-second* *:syn-sync-ccomment*
3863
3864For the second method, only the "ccomment" argument needs to be given.
3865Example: >
3866 :syntax sync ccomment
3867
3868When Vim finds that the line where displaying starts is inside a C-style
3869comment, the last region syntax item with the group-name "Comment" will be
3870used. This requires that there is a region with the group-name "Comment"!
3871An alternate group name can be specified, for example: >
3872 :syntax sync ccomment javaComment
3873This means that the last item specified with "syn region javaComment" will be
3874used for the detected C comment region. This only works properly if that
3875region does have a start pattern "\/*" and an end pattern "*\/".
3876
3877The "maxlines" argument can be used to restrict the search to a number of
3878lines. The "minlines" argument can be used to at least start a number of
3879lines back (e.g., for when there is some construct that only takes a few
3880lines, but it hard to sync on).
3881
3882Note: Syncing on a C comment doesn't work properly when strings are used
3883that cross a line and contain a "*/". Since letting strings cross a line
3884is a bad programming habit (many compilers give a warning message), and the
3885chance of a "*/" appearing inside a comment is very small, this restriction
3886is hardly ever noticed.
3887
3888
3889Third syncing method: *:syn-sync-third*
3890
3891For the third method, only the "minlines={N}" argument needs to be given.
3892Vim will subtract {N} from the line number and start parsing there. This
3893means {N} extra lines need to be parsed, which makes this method a bit slower.
3894Example: >
3895 :syntax sync minlines=50
3896
3897"lines" is equivalent to "minlines" (used by older versions).
3898
3899
3900Fourth syncing method: *:syn-sync-fourth*
3901
3902The idea is to synchronize on the end of a few specific regions, called a
3903sync pattern. Only regions can cross lines, so when we find the end of some
3904region, we might be able to know in which syntax item we are. The search
3905starts in the line just above the one where redrawing starts. From there
3906the search continues backwards in the file.
3907
3908This works just like the non-syncing syntax items. You can use contained
3909matches, nextgroup, etc. But there are a few differences:
3910- Keywords cannot be used.
3911- The syntax items with the "sync" keyword form a completely separated group
3912 of syntax items. You can't mix syncing groups and non-syncing groups.
3913- The matching works backwards in the buffer (line by line), instead of
3914 forwards.
3915- A line continuation pattern can be given. It is used to decide which group
3916 of lines need to be searched like they were one line. This means that the
3917 search for a match with the specified items starts in the first of the
3918 consecutive that contain the continuation pattern.
3919- When using "nextgroup" or "contains", this only works within one line (or
3920 group of continued lines).
3921- When using a region, it must start and end in the same line (or group of
3922 continued lines). Otherwise the end is assumed to be at the end of the
3923 line (or group of continued lines).
3924- When a match with a sync pattern is found, the rest of the line (or group of
3925 continued lines) is searched for another match. The last match is used.
3926 This is used when a line can contain both the start end the end of a region
3927 (e.g., in a C-comment like /* this */, the last "*/" is used).
3928
3929There are two ways how a match with a sync pattern can be used:
39301. Parsing for highlighting starts where redrawing starts (and where the
3931 search for the sync pattern started). The syntax group that is expected
3932 to be valid there must be specified. This works well when the regions
3933 that cross lines cannot contain other regions.
39342. Parsing for highlighting continues just after the match. The syntax group
3935 that is expected to be present just after the match must be specified.
3936 This can be used when the previous method doesn't work well. It's much
3937 slower, because more text needs to be parsed.
3938Both types of sync patterns can be used at the same time.
3939
3940Besides the sync patterns, other matches and regions can be specified, to
3941avoid finding unwanted matches.
3942
3943[The reason that the sync patterns are given separately, is that mostly the
3944search for the sync point can be much simpler than figuring out the
3945highlighting. The reduced number of patterns means it will go (much)
3946faster.]
3947
3948 *syn-sync-grouphere* *E393* *E394*
3949 :syntax sync match {sync-group-name} grouphere {group-name} "pattern" ..
3950
3951 Define a match that is used for syncing. {group-name} is the
3952 name of a syntax group that follows just after the match. Parsing
3953 of the text for highlighting starts just after the match. A region
3954 must exist for this {group-name}. The first one defined will be used.
3955 "NONE" can be used for when there is no syntax group after the match.
3956
3957 *syn-sync-groupthere*
3958 :syntax sync match {sync-group-name} groupthere {group-name} "pattern" ..
3959
3960 Like "grouphere", but {group-name} is the name of a syntax group that
3961 is to be used at the start of the line where searching for the sync
3962 point started. The text between the match and the start of the sync
3963 pattern searching is assumed not to change the syntax highlighting.
3964 For example, in C you could search backwards for "/*" and "*/". If
3965 "/*" is found first, you know that you are inside a comment, so the
3966 "groupthere" is "cComment". If "*/" is found first, you know that you
3967 are not in a comment, so the "groupthere" is "NONE". (in practice
3968 it's a bit more complicated, because the "/*" and "*/" could appear
3969 inside a string. That's left as an exercise to the reader...).
3970
3971 :syntax sync match ..
3972 :syntax sync region ..
3973
3974 Without a "groupthere" argument. Define a region or match that is
3975 skipped while searching for a sync point.
3976
Bram Moolenaarc9b4b052006-04-30 18:54:39 +00003977 *syn-sync-linecont*
Bram Moolenaar071d4272004-06-13 20:20:40 +00003978 :syntax sync linecont {pattern}
3979
3980 When {pattern} matches in a line, it is considered to continue in
3981 the next line. This means that the search for a sync point will
3982 consider the lines to be concatenated.
3983
3984If the "maxlines={N}" argument is given too, the number of lines that are
3985searched for a match is restricted to N. This is useful if you have very
3986few things to sync on and a slow machine. Example: >
3987 :syntax sync maxlines=100
3988
3989You can clear all sync settings with: >
3990 :syntax sync clear
3991
3992You can clear specific sync patterns with: >
3993 :syntax sync clear {sync-group-name} ..
3994

399611. Listing syntax items *:syntax* *:sy* *:syn* *:syn-list*
3997
Bram Moolenaar482aaeb2005-09-29 18:26:07 +00003998This command lists all the syntax items: >

4003
4004 :sy[ntax] list {group-name}
4005
Bram Moolenaar24ea3ba2010-09-19 19:01:21 +02004006To list the syntax groups in one cluster: *E392* >

4008 :sy[ntax] list @{cluster-name}
4009
4010See above for other arguments for the ":syntax" command.
4011
4012Note that the ":syntax" command can be abbreviated to ":sy", although ":syn"
4013is mostly used, because it looks better.
4014
4015==============================================================================
401612. Highlight command *:highlight* *:hi* *E28* *E411* *E415*
4017
4018There are three types of highlight groups:
4019- The ones used for specific languages. For these the name starts with the
4020 name of the language. Many of these don't have any attributes, but are
4021 linked to a group of the second type.
4022- The ones used for all syntax languages.
4023- The ones used for the 'highlight' option.
4024 *hitest.vim*
4025You can see all the groups currently active with this command: >
4026 :so $VIMRUNTIME/syntax/hitest.vim
4027This will open a new window containing all highlight group names, displayed
4028in their own color.
4029
4030 *:colo* *:colorscheme* *E185*
Bram Moolenaar00a927d2010-05-14 23:24:24 +02004031:colo[rscheme] Output the name of the currently active color scheme.
4032 This is basically the same as >
4033 :echo g:colors_name
4034< In case g:colors_name has not been defined :colo will
4035 output "default". When compiled without the |+eval|
4036 feature it will output "unknown".
4037
Bram Moolenaar071d4272004-06-13 20:20:40 +00004038:colo[rscheme] {name} Load color scheme {name}. This searches 'runtimepath'
4039 for the file "colors/{name}.vim. The first one that
4040 is found is loaded.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01004041 To see the name of the currently active color scheme: >
Bram Moolenaar00a927d2010-05-14 23:24:24 +02004042 :colo
4043< The name is also stored in the g:colors_name variable.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01004044 Doesn't work recursively, thus you can't use
Bram Moolenaar071d4272004-06-13 20:20:40 +00004045 ":colorscheme" in a color scheme script.
Bram Moolenaarcfbc5ee2004-07-02 15:38:35 +00004046 After the color scheme has been loaded the
4047 |ColorScheme| autocommand event is triggered.

Bram Moolenaar071d4272004-06-13 20:20:40 +00004050
4051:hi[ghlight] List all the current highlight groups that have
4052 attributes set.
4053
4054:hi[ghlight] {group-name}
4055 List one highlight group.
4056
4057:hi[ghlight] clear Reset all highlighting to the defaults. Removes all
4058 highlighting for groups added by the user!
4059 Uses the current value of 'background' to decide which
4060 default colors to use.
4061
4062:hi[ghlight] clear {group-name}
4063:hi[ghlight] {group-name} NONE
4064 Disable the highlighting for one highlight group. It
4065 is _not_ set back to the default colors.
4066
4067:hi[ghlight] [default] {group-name} {key}={arg} ..
4068 Add a highlight group, or change the highlighting for
4069 an existing group.
4070 See |highlight-args| for the {key}={arg} arguments.
4071 See |:highlight-default| for the optional [default]
4072 argument.
4073
4074Normally a highlight group is added once when starting up. This sets the
4075default values for the highlighting. After that, you can use additional
4076highlight commands to change the arguments that you want to set to non-default
4077values. The value "NONE" can be used to switch the value off or go back to
4078the default value.
4079
4080A simple way to change colors is with the |:colorscheme| command. This loads
4081a file with ":highlight" commands such as this: >
4082
4083 :hi Comment gui=bold
4084
4085Note that all settings that are not included remain the same, only the
4086specified field is used, and settings are merged with previous ones. So, the
4087result is like this single command has been used: >

Bram Moolenaar661b1822005-07-28 22:36:45 +00004091When listing a highlight group and 'verbose' is non-zero, the listing will
4092also tell where it was last set. Example: >

Bram Moolenaar8aff23a2005-08-19 20:40:30 +00004097When ":hi clear" is used then the script where this command is used will be
4098mentioned for the default values. See |:verbose-cmd| for more information.

Bram Moolenaar071d4272004-06-13 20:20:40 +00004100 *highlight-args* *E416* *E417* *E423*
4101There are three types of terminals for highlighting:
4102term a normal terminal (vt100, xterm)
4103cterm a color terminal (MS-DOS console, color-xterm, these have the "Co"
4104 termcap entry)
4105gui the GUI
4106
4107For each type the highlighting can be given. This makes it possible to use
4108the same syntax file on all terminals, and use the optimal highlighting.
4109
41101. highlight arguments for normal terminals
4111
Bram Moolenaar75c50c42005-06-04 22:06:24 +00004112 *bold* *underline* *undercurl*
4113 *inverse* *italic* *standout*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004114term={attr-list} *attr-list* *highlight-term* *E418*
4115 attr-list is a comma separated list (without spaces) of the
4116 following items (in any order):
4117 bold
4118 underline
Bram Moolenaar5409c052005-03-18 20:27:04 +00004119 undercurl not always available
Bram Moolenaar071d4272004-06-13 20:20:40 +00004120 reverse
4121 inverse same as reverse
4122 italic
4123 standout
4124 NONE no attributes used (used to reset it)
4125
4126 Note that "bold" can be used here and by using a bold font. They
4127 have the same effect.
Bram Moolenaar5409c052005-03-18 20:27:04 +00004128 "undercurl" is a curly underline. When "undercurl" is not possible
4129 then "underline" is used. In general "undercurl" is only available in
Bram Moolenaar910f66f2006-04-05 20:41:53 +00004130 the GUI. The color is set with |highlight-guisp|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004131
4132start={term-list} *highlight-start* *E422*
4133stop={term-list} *term-list* *highlight-stop*
4134 These lists of terminal codes can be used to get
4135 non-standard attributes on a terminal.
4136
4137 The escape sequence specified with the "start" argument
4138 is written before the characters in the highlighted
4139 area. It can be anything that you want to send to the
4140 terminal to highlight this area. The escape sequence
4141 specified with the "stop" argument is written after the
4142 highlighted area. This should undo the "start" argument.
4143 Otherwise the screen will look messed up.
4144
4145 The {term-list} can have two forms:
4146
4147 1. A string with escape sequences.
4148 This is any string of characters, except that it can't start with
4149 "t_" and blanks are not allowed. The <> notation is recognized
4150 here, so you can use things like "<Esc>" and "<Space>". Example:
4151 start=<Esc>[27h;<Esc>[<Space>r;
4152
4153 2. A list of terminal codes.
4154 Each terminal code has the form "t_xx", where "xx" is the name of
4155 the termcap entry. The codes have to be separated with commas.
4156 White space is not allowed. Example:
4157 start=t_C1,t_BL
4158 The terminal codes must exist for this to work.
4159
4160
41612. highlight arguments for color terminals
4162
4163cterm={attr-list} *highlight-cterm*
4164 See above for the description of {attr-list} |attr-list|.
4165 The "cterm" argument is likely to be different from "term", when
4166 colors are used. For example, in a normal terminal comments could
4167 be underlined, in a color terminal they can be made Blue.
4168 Note: Many terminals (e.g., DOS console) can't mix these attributes
4169 with coloring. Use only one of "cterm=" OR "ctermfg=" OR "ctermbg=".
4170
4171ctermfg={color-nr} *highlight-ctermfg* *E421*
4172ctermbg={color-nr} *highlight-ctermbg*
4173 The {color-nr} argument is a color number. Its range is zero to
4174 (not including) the number given by the termcap entry "Co".
4175 The actual color with this number depends on the type of terminal
4176 and its settings. Sometimes the color also depends on the settings of
4177 "cterm". For example, on some systems "cterm=bold ctermfg=3" gives
4178 another color, on others you just get color 3.
4179
4180 For an xterm this depends on your resources, and is a bit
4181 unpredictable. See your xterm documentation for the defaults. The
4182 colors for a color-xterm can be changed from the .Xdefaults file.
4183 Unfortunately this means that it's not possible to get the same colors
4184 for each user. See |xterm-color| for info about color xterms.
4185
4186 The MSDOS standard colors are fixed (in a console window), so these
4187 have been used for the names. But the meaning of color names in X11
4188 are fixed, so these color settings have been used, to make the
4189 highlighting settings portable (complicated, isn't it?). The
4190 following names are recognized, with the color number used:
4191
4192 *cterm-colors*
4193 NR-16 NR-8 COLOR NAME ~
4194 0 0 Black
4195 1 4 DarkBlue
4196 2 2 DarkGreen
4197 3 6 DarkCyan
4198 4 1 DarkRed
4199 5 5 DarkMagenta
4200 6 3 Brown, DarkYellow
4201 7 7 LightGray, LightGrey, Gray, Grey
4202 8 0* DarkGray, DarkGrey
4203 9 4* Blue, LightBlue
4204 10 2* Green, LightGreen
4205 11 6* Cyan, LightCyan
4206 12 1* Red, LightRed
4207 13 5* Magenta, LightMagenta
4208 14 3* Yellow, LightYellow
4209 15 7* White
4210
4211 The number under "NR-16" is used for 16-color terminals ('t_Co'
4212 greater than or equal to 16). The number under "NR-8" is used for
4213 8-color terminals ('t_Co' less than 16). The '*' indicates that the
4214 bold attribute is set for ctermfg. In many 8-color terminals (e.g.,
4215 "linux"), this causes the bright colors to appear. This doesn't work
4216 for background colors! Without the '*' the bold attribute is removed.
4217 If you want to set the bold attribute in a different way, put a
4218 "cterm=" argument AFTER the "ctermfg=" or "ctermbg=" argument. Or use
4219 a number instead of a color name.
4220
4221 The case of the color names is ignored.
4222 Note that for 16 color ansi style terminals (including xterms), the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004223 numbers in the NR-8 column is used. Here '*' means 'add 8' so that Blue
Bram Moolenaar071d4272004-06-13 20:20:40 +00004224 is 12, DarkGray is 8 etc.
4225
4226 Note that for some color terminals these names may result in the wrong
4227 colors!
4228
4229 *:hi-normal-cterm*
4230 When setting the "ctermfg" or "ctermbg" colors for the Normal group,
4231 these will become the colors used for the non-highlighted text.
4232 Example: >
4233 :highlight Normal ctermfg=grey ctermbg=darkblue
4234< When setting the "ctermbg" color for the Normal group, the
4235 'background' option will be adjusted automatically. This causes the
4236 highlight groups that depend on 'background' to change! This means
4237 you should set the colors for Normal first, before setting other
4238 colors.
4239 When a colorscheme is being used, changing 'background' causes it to
4240 be reloaded, which may reset all colors (including Normal). First
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01004241 delete the "g:colors_name" variable when you don't want this.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004242
4243 When you have set "ctermfg" or "ctermbg" for the Normal group, Vim
4244 needs to reset the color when exiting. This is done with the "op"
4245 termcap entry |t_op|. If this doesn't work correctly, try setting the
4246 't_op' option in your .vimrc.
4247 *E419* *E420*
4248 When Vim knows the normal foreground and background colors, "fg" and
4249 "bg" can be used as color names. This only works after setting the
4250 colors for the Normal group and for the MS-DOS console. Example, for
4251 reverse video: >
4252 :highlight Visual ctermfg=bg ctermbg=fg
4253< Note that the colors are used that are valid at the moment this
4254 command are given. If the Normal group colors are changed later, the
4255 "fg" and "bg" colors will not be adjusted.
4256
4257
42583. highlight arguments for the GUI
4259
4260gui={attr-list} *highlight-gui*
4261 These give the attributes to use in the GUI mode.
4262 See |attr-list| for a description.
4263 Note that "bold" can be used here and by using a bold font. They
4264 have the same effect.
4265 Note that the attributes are ignored for the "Normal" group.
4266
4267font={font-name} *highlight-font*
4268 font-name is the name of a font, as it is used on the system Vim
4269 runs on. For X11 this is a complicated name, for example: >
4270 font=-misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1
4271<
4272 The font-name "NONE" can be used to revert to the default font.
4273 When setting the font for the "Normal" group, this becomes the default
4274 font (until the 'guifont' option is changed; the last one set is
4275 used).
4276 The following only works with Motif and Athena, not with other GUIs:
4277 When setting the font for the "Menu" group, the menus will be changed.
4278 When setting the font for the "Tooltip" group, the tooltips will be
4279 changed.
4280 All fonts used, except for Menu and Tooltip, should be of the same
4281 character size as the default font! Otherwise redrawing problems will
4282 occur.
4283
4284guifg={color-name} *highlight-guifg*
4285guibg={color-name} *highlight-guibg*
Bram Moolenaar5409c052005-03-18 20:27:04 +00004286guisp={color-name} *highlight-guisp*
4287 These give the foreground (guifg), background (guibg) and special
Bram Moolenaar7df351e2006-01-23 22:30:28 +00004288 (guisp) color to use in the GUI. "guisp" is used for undercurl.
4289 There are a few special names:
Bram Moolenaar071d4272004-06-13 20:20:40 +00004290 NONE no color (transparent)
4291 bg use normal background color
4292 background use normal background color
4293 fg use normal foreground color
4294 foreground use normal foreground color
4295 To use a color name with an embedded space or other special character,
4296 put it in single quotes. The single quote cannot be used then.
4297 Example: >
4298 :hi comment guifg='salmon pink'
4299<
4300 *gui-colors*
4301 Suggested color names (these are available on most systems):
4302 Red LightRed DarkRed
4303 Green LightGreen DarkGreen SeaGreen
4304 Blue LightBlue DarkBlue SlateBlue
4305 Cyan LightCyan DarkCyan
4306 Magenta LightMagenta DarkMagenta
4307 Yellow LightYellow Brown DarkYellow
4308 Gray LightGray DarkGray
4309 Black White
4310 Orange Purple Violet
4311
4312 In the Win32 GUI version, additional system colors are available. See
4313 |win32-colors|.
4314
4315 You can also specify a color by its Red, Green and Blue values.
4316 The format is "#rrggbb", where
4317 "rr" is the Red value
Bram Moolenaar071d4272004-06-13 20:20:40 +00004318 "gg" is the Green value
Bram Moolenaar5409c052005-03-18 20:27:04 +00004319 "bb" is the Blue value
Bram Moolenaar071d4272004-06-13 20:20:40 +00004320 All values are hexadecimal, range from "00" to "ff". Examples: >
4321 :highlight Comment guifg=#11f0c3 guibg=#ff00ff
4322<
4323 *highlight-groups* *highlight-default*
4324These are the default highlighting groups. These groups are used by the
4325'highlight' option default. Note that the highlighting depends on the value
4326of 'background'. You can see the current settings with the ":highlight"
4327command.

Bram Moolenaarf75a9632005-09-13 21:20:47 +00004441 *hl-User1* *hl-User1..9* *hl-User9*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004442The 'statusline' syntax allows the use of 9 different highlights in the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004443statusline and ruler (via 'rulerformat'). The names are User1 to User9.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004444
Bram Moolenaar8c8de832008-06-24 22:58:06 +00004445For the GUI you can use the following groups to set the colors for the menu,
Bram Moolenaar071d4272004-06-13 20:20:40 +00004446scrollbars and tooltips. They don't have defaults. This doesn't work for the
4447Win32 GUI. Only three highlight arguments have any effect here: font, guibg,
4448and guifg.
4449
4450 *hl-Menu*
4451Menu Current font, background and foreground colors of the menus.
4452 Also used for the toolbar.
4453 Applicable highlight arguments: font, guibg, guifg.
4454
4455 NOTE: For Motif and Athena the font argument actually
4456 specifies a fontset at all times, no matter if 'guifontset' is
4457 empty, and as such it is tied to the current |:language| when
4458 set.
4459
4460 *hl-Scrollbar*
4461Scrollbar Current background and foreground of the main window's
4462 scrollbars.
4463 Applicable highlight arguments: guibg, guifg.
4464
4465 *hl-Tooltip*
4466Tooltip Current font, background and foreground of the tooltips.
4467 Applicable highlight arguments: font, guibg, guifg.
4468
4469 NOTE: For Motif and Athena the font argument actually
4470 specifies a fontset at all times, no matter if 'guifontset' is
4471 empty, and as such it is tied to the current |:language| when
4472 set.
4473
4474==============================================================================
447513. Linking groups *:hi-link* *:highlight-link* *E412* *E413*
4476
4477When you want to use the same highlighting for several syntax groups, you
4478can do this more easily by linking the groups into one common highlight
4479group, and give the color attributes only for that group.
4480
4481To set a link:
4482
4483 :hi[ghlight][!] [default] link {from-group} {to-group}
4484
4485To remove a link:
4486
4487 :hi[ghlight][!] [default] link {from-group} NONE
4488
4489Notes: *E414*
4490- If the {from-group} and/or {to-group} doesn't exist, it is created. You
4491 don't get an error message for a non-existing group.
4492- As soon as you use a ":highlight" command for a linked group, the link is
4493 removed.
4494- If there are already highlight settings for the {from-group}, the link is
4495 not made, unless the '!' is given. For a ":highlight link" command in a
4496 sourced file, you don't get an error message. This can be used to skip
4497 links for groups that already have settings.
4498
4499 *:hi-default* *:highlight-default*
4500The [default] argument is used for setting the default highlighting for a
4501group. If highlighting has already been specified for the group the command
4502will be ignored. Also when there is an existing link.
4503
4504Using [default] is especially useful to overrule the highlighting of a
4505specific syntax file. For example, the C syntax file contains: >
4506 :highlight default link cComment Comment
4507If you like Question highlighting for C comments, put this in your vimrc file: >
4508 :highlight link cComment Question
4509Without the "default" in the C syntax file, the highlighting would be
4510overruled when the syntax file is loaded.
4511
4512==============================================================================
451314. Cleaning up *:syn-clear* *E391*
4514
4515If you want to clear the syntax stuff for the current buffer, you can use this
4516command: >
4517 :syntax clear
4518
4519This command should be used when you want to switch off syntax highlighting,
4520or when you want to switch to using another syntax. It's normally not needed
4521in a syntax file itself, because syntax is cleared by the autocommands that
4522load the syntax file.
4523The command also deletes the "b:current_syntax" variable, since no syntax is
4524loaded after this command.
4525
4526If you want to disable syntax highlighting for all buffers, you need to remove
4527the autocommands that load the syntax files: >
4528 :syntax off
4529
4530What this command actually does, is executing the command >
4531 :source $VIMRUNTIME/syntax/nosyntax.vim
4532See the "nosyntax.vim" file for details. Note that for this to work
4533$VIMRUNTIME must be valid. See |$VIMRUNTIME|.
4534
4535To clean up specific syntax groups for the current buffer: >
4536 :syntax clear {group-name} ..
4537This removes all patterns and keywords for {group-name}.
4538
4539To clean up specific syntax group lists for the current buffer: >
4540 :syntax clear @{grouplist-name} ..
4541This sets {grouplist-name}'s contents to an empty list.
4542
4543 *:syntax-reset* *:syn-reset*
4544If you have changed the colors and messed them up, use this command to get the
4545defaults back: >
4546
4547 :syntax reset
4548
4549This doesn't change the colors for the 'highlight' option.
4550
4551Note that the syntax colors that you set in your vimrc file will also be reset
4552back to their Vim default.
4553Note that if you are using a color scheme, the colors defined by the color
4554scheme for syntax highlighting will be lost.
4555
4556What this actually does is: >
4557
4558 let g:syntax_cmd = "reset"
4559 runtime! syntax/syncolor.vim
4560
4561Note that this uses the 'runtimepath' option.
4562
4563 *syncolor*
4564If you want to use different colors for syntax highlighting, you can add a Vim
4565script file to set these colors. Put this file in a directory in
4566'runtimepath' which comes after $VIMRUNTIME, so that your settings overrule
4567the default colors. This way these colors will be used after the ":syntax
4568reset" command.
4569
4570For Unix you can use the file ~/.vim/after/syntax/syncolor.vim. Example: >
4571
4572 if &background == "light"
4573 highlight comment ctermfg=darkgreen guifg=darkgreen
4574 else
4575 highlight comment ctermfg=green guifg=green
4576 endif
4577
Bram Moolenaarc0197e22004-09-13 20:26:32 +00004578 *E679*
4579Do make sure this syncolor.vim script does not use a "syntax on", set the
4580'background' option or uses a "colorscheme" command, because it results in an
4581endless loop.
4582
Bram Moolenaar071d4272004-06-13 20:20:40 +00004583Note that when a color scheme is used, there might be some confusion whether
4584your defined colors are to be used or the colors from the scheme. This
4585depends on the color scheme file. See |:colorscheme|.
4586
4587 *syntax_cmd*
4588The "syntax_cmd" variable is set to one of these values when the
4589syntax/syncolor.vim files are loaded:
4590 "on" ":syntax on" command. Highlight colors are overruled but
4591 links are kept
4592 "enable" ":syntax enable" command. Only define colors for groups that
4593 don't have highlighting yet. Use ":syntax default".
4594 "reset" ":syntax reset" command or loading a color scheme. Define all
4595 the colors.
4596 "skip" Don't define colors. Used to skip the default settings when a
4597 syncolor.vim file earlier in 'runtimepath' has already set
4598 them.
4599
4600==============================================================================
460115. Highlighting tags *tag-highlight*
4602
4603If you want to highlight all the tags in your file, you can use the following
4604mappings.
4605
4606 <F11> -- Generate tags.vim file, and highlight tags.
4607 <F12> -- Just highlight tags based on existing tags.vim file.
4608>
4609 :map <F11> :sp tags<CR>:%s/^\([^ :]*:\)\=\([^ ]*\).*/syntax keyword Tag \2/<CR>:wq! tags.vim<CR>/^<CR><F12>
4610 :map <F12> :so tags.vim<CR>
4611
4612WARNING: The longer the tags file, the slower this will be, and the more
4613memory Vim will consume.
4614
4615Only highlighting typedefs, unions and structs can be done too. For this you
4616must use Exuberant ctags (found at http://ctags.sf.net).
4617
4618Put these lines in your Makefile:
4619
4620# Make a highlight file for types. Requires Exuberant ctags and awk
4621types: types.vim
4622types.vim: *.[ch]
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00004623 ctags --c-kinds=gstu -o- *.[ch] |\
Bram Moolenaar071d4272004-06-13 20:20:40 +00004624 awk 'BEGIN{printf("syntax keyword Type\t")}\
4625 {printf("%s ", $$1)}END{print ""}' > $@
4626
4627And put these lines in your .vimrc: >
4628
4629 " load the types.vim highlighting file, if it exists
4630 autocmd BufRead,BufNewFile *.[ch] let fname = expand('<afile>:p:h') . '/types.vim'
4631 autocmd BufRead,BufNewFile *.[ch] if filereadable(fname)
4632 autocmd BufRead,BufNewFile *.[ch] exe 'so ' . fname
4633 autocmd BufRead,BufNewFile *.[ch] endif
4634
4635==============================================================================
Bram Moolenaar860cae12010-06-05 23:22:07 +0200463616. Window-local syntax *:ownsyntax*
4637
4638Normally all windows on a buffer share the same syntax settings. It is
4639possible, however, to set a particular window on a file to have its own
4640private syntax setting. A possible example would be to edit LaTeX source
4641with conventional highlighting in one window, while seeing the same source
4642highlighted differently (so as to hide control sequences and indicate bold,
4643italic etc regions) in another. The 'scrollbind' option is useful here.
4644
4645To set the current window to have the syntax "foo", separately from all other
4646windows on the buffer: >
4647 :ownsyntax foo
Bram Moolenaardebe25a2010-06-06 17:41:24 +02004648< *w:current_syntax*
4649This will set the "w:current_syntax" variable to "foo". The value of
4650"b:current_syntax" does not change. This is implemented by saving and
4651restoring "b:current_syntax", since the syntax files do set
4652"b:current_syntax". The value set by the syntax file is assigned to
4653"w:current_syntax".
Bram Moolenaar860cae12010-06-05 23:22:07 +02004654
4655Once a window has its own syntax, syntax commands executed from other windows
4656on the same buffer (including :syntax clear) have no effect. Conversely,
4657syntax commands executed from that window do not effect other windows on the
4658same buffer.
4659
Bram Moolenaardebe25a2010-06-06 17:41:24 +02004660A window with its own syntax reverts to normal behavior when another buffer
4661is loaded into that window or the file is reloaded.
4662When splitting the window, the new window will use the original syntax.
Bram Moolenaar860cae12010-06-05 23:22:07 +02004663
4664==============================================================================
Bram Moolenaar24ea3ba2010-09-19 19:01:21 +0200466517. Color xterms *xterm-color* *color-xterm*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004666
4667Most color xterms have only eight colors. If you don't get colors with the
4668default setup, it should work with these lines in your .vimrc: >
4669 :if &term =~ "xterm"
4670 : if has("terminfo")
4671 : set t_Co=8
4672 : set t_Sf=<Esc>[3%p1%dm
4673 : set t_Sb=<Esc>[4%p1%dm
4674 : else
4675 : set t_Co=8
4676 : set t_Sf=<Esc>[3%dm
4677 : set t_Sb=<Esc>[4%dm
4678 : endif
4679 :endif
4680< [<Esc> is a real escape, type CTRL-V <Esc>]
4681
4682You might want to change the first "if" to match the name of your terminal,
4683e.g. "dtterm" instead of "xterm".
4684
4685Note: Do these settings BEFORE doing ":syntax on". Otherwise the colors may
4686be wrong.
4687 *xiterm* *rxvt*
4688The above settings have been mentioned to work for xiterm and rxvt too.
4689But for using 16 colors in an rxvt these should work with terminfo: >
4690 :set t_AB=<Esc>[%?%p1%{8}%<%t25;%p1%{40}%+%e5;%p1%{32}%+%;%dm
4691 :set t_AF=<Esc>[%?%p1%{8}%<%t22;%p1%{30}%+%e1;%p1%{22}%+%;%dm
4692<
4693 *colortest.vim*
4694To test your color setup, a file has been included in the Vim distribution.
Bram Moolenaarf740b292006-02-16 22:11:02 +00004695To use it, execute this command: >
4696 :runtime syntax/colortest.vim
Bram Moolenaar071d4272004-06-13 20:20:40 +00004697
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004698Some versions of xterm (and other terminals, like the Linux console) can
Bram Moolenaar071d4272004-06-13 20:20:40 +00004699output lighter foreground colors, even though the number of colors is defined
4700at 8. Therefore Vim sets the "cterm=bold" attribute for light foreground
4701colors, when 't_Co' is 8.
4702
4703 *xfree-xterm*
4704To get 16 colors or more, get the newest xterm version (which should be
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004705included with XFree86 3.3 and later). You can also find the latest version
Bram Moolenaar071d4272004-06-13 20:20:40 +00004706at: >
4707 http://invisible-island.net/xterm/xterm.html
4708Here is a good way to configure it. This uses 88 colors and enables the
4709termcap-query feature, which allows Vim to ask the xterm how many colors it
4710supports. >
4711 ./configure --disable-bold-color --enable-88-color --enable-tcap-query
4712If you only get 8 colors, check the xterm compilation settings.
4713(Also see |UTF8-xterm| for using this xterm with UTF-8 character encoding).
4714
4715This xterm should work with these lines in your .vimrc (for 16 colors): >
4716 :if has("terminfo")
4717 : set t_Co=16
4718 : set t_AB=<Esc>[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{92}%+%;%dm
4719 : set t_AF=<Esc>[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{82}%+%;%dm
4720 :else
4721 : set t_Co=16
4722 : set t_Sf=<Esc>[3%dm
4723 : set t_Sb=<Esc>[4%dm
4724 :endif
4725< [<Esc> is a real escape, type CTRL-V <Esc>]
4726
4727Without |+terminfo|, Vim will recognize these settings, and automatically
4728translate cterm colors of 8 and above to "<Esc>[9%dm" and "<Esc>[10%dm".
4729Colors above 16 are also translated automatically.
4730
4731For 256 colors this has been reported to work: >
4732
4733 :set t_AB=<Esc>[48;5;%dm
4734 :set t_AF=<Esc>[38;5;%dm
4735
4736Or just set the TERM environment variable to "xterm-color" or "xterm-16color"
4737and try if that works.
4738
4739You probably want to use these X resources (in your ~/.Xdefaults file):
4740 XTerm*color0: #000000
4741 XTerm*color1: #c00000
4742 XTerm*color2: #008000
4743 XTerm*color3: #808000
4744 XTerm*color4: #0000c0
4745 XTerm*color5: #c000c0
4746 XTerm*color6: #008080
4747 XTerm*color7: #c0c0c0
4748 XTerm*color8: #808080
4749 XTerm*color9: #ff6060
4750 XTerm*color10: #00ff00
4751 XTerm*color11: #ffff00
4752 XTerm*color12: #8080ff
4753 XTerm*color13: #ff40ff
4754 XTerm*color14: #00ffff
4755 XTerm*color15: #ffffff
4756 Xterm*cursorColor: Black
4757
4758[Note: The cursorColor is required to work around a bug, which changes the
4759cursor color to the color of the last drawn text. This has been fixed by a
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00004760newer version of xterm, but not everybody is using it yet.]
Bram Moolenaar071d4272004-06-13 20:20:40 +00004761
4762To get these right away, reload the .Xdefaults file to the X Option database
4763Manager (you only need to do this when you just changed the .Xdefaults file): >
4764 xrdb -merge ~/.Xdefaults
4765<
4766 *xterm-blink* *xterm-blinking-cursor*
4767To make the cursor blink in an xterm, see tools/blink.c. Or use Thomas
4768Dickey's xterm above patchlevel 107 (see above for where to get it), with
4769these resources:
4770 XTerm*cursorBlink: on
4771 XTerm*cursorOnTime: 400
4772 XTerm*cursorOffTime: 250
4773 XTerm*cursorColor: White
4774
4775 *hpterm-color*
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00004776These settings work (more or less) for an hpterm, which only supports 8
Bram Moolenaar071d4272004-06-13 20:20:40 +00004777foreground colors: >
4778 :if has("terminfo")
4779 : set t_Co=8
4780 : set t_Sf=<Esc>[&v%p1%dS
4781 : set t_Sb=<Esc>[&v7S
4782 :else
4783 : set t_Co=8
4784 : set t_Sf=<Esc>[&v%dS
4785 : set t_Sb=<Esc>[&v7S
4786 :endif
4787< [<Esc> is a real escape, type CTRL-V <Esc>]
4788
4789 *Eterm* *enlightened-terminal*
4790These settings have been reported to work for the Enlightened terminal
4791emulator, or Eterm. They might work for all xterm-like terminals that use the
4792bold attribute to get bright colors. Add an ":if" like above when needed. >
4793 :set t_Co=16
4794 :set t_AF=^[[%?%p1%{8}%<%t3%p1%d%e%p1%{22}%+%d;1%;m
4795 :set t_AB=^[[%?%p1%{8}%<%t4%p1%d%e%p1%{32}%+%d;1%;m
4796<
4797 *TTpro-telnet*
4798These settings should work for TTpro telnet. Tera Term Pro is a freeware /
4799open-source program for MS-Windows. >
4800 set t_Co=16
4801 set t_AB=^[[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{32}%+5;%;%dm
4802 set t_AF=^[[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{22}%+1;%;%dm
4803Also make sure TTpro's Setup / Window / Full Color is enabled, and make sure
4804that Setup / Font / Enable Bold is NOT enabled.
