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 Moolenaar166af9b2010-11-16 20:34:40 +0100478For diff mode on a single file (with g:html_diff_one_file) a sequence of more
479than 3 filler lines is displayed as three lines with the middle line
480mentioning the total number of inserted lines. If you prefer to see all the
481inserted lines as with the side-by-side diff, use: >
Bram Moolenaar349b2fb2010-07-16 20:35:36 +0200482 :let g:html_whole_filler = 1
Bram Moolenaar47136d72004-10-12 20:02:24 +0000483And to go back to displaying up to three lines again: >

Bram Moolenaar488c6512005-08-11 20:09:58 +0000485<
Bram Moolenaar166af9b2010-11-16 20:34:40 +0100486TOhtml uses the current value of 'fileencoding' if set, or 'encoding' if not,
487to determine the charset and 'fileencoding' of the HTML file. In general, this
488works for the encodings mentioned specifically by name in |encoding-names|, but
489TOhtml will only automatically use those encodings which are widely supported.
490However, you can override this to support specific encodings that may not be
491automatically detected by default.
492
493To overrule all automatic charset detection, set g:html_use_encoding to the
494name of the charset to be used. TOhtml will try to determine the appropriate
495'fileencoding' setting from the charset, but you may need to set it manually
496if TOhtml cannot determine the encoding. It is recommended to set this
497variable to something widely supported, like UTF-8, for anything you will be
498hosting on a webserver: >
499 :let g:html_use_encoding = "UTF-8"
500You can also use this option to omit the line that specifies the charset
501entirely, by setting g:html_use_encoding to an empty string: >
502 :let g:html_use_encoding = ""
503To go back to the automatic mechanism, delete the g:html_use_encoding
504variable: >
505 :unlet g:html_use_encoding
506
507If you specify a charset with g:html_use_encoding for which TOhtml cannot
508automatically detect the corresponding 'fileencoding' setting, you can use
509g:html_encoding_override to allow TOhtml to detect the correct encoding.
510This is a dictionary of charset-encoding pairs that will replace existing
511pairs automatically detected by TOhtml, or supplement with new pairs. For
512example, to allow TOhtml to detect the HTML charset "windows-1252" properly as
513the encoding "8bit-cp1252", use: >
514 :let g:html_encoding_override = {'windows-1252': '8bit-cp1252'}
515<
516The g:html_charset_override is similar, it allows TOhtml to detect the HTML
517charset for any 'fileencoding' or 'encoding' which is not detected
518automatically. You can also use it to override specific existing
519encoding-charset pairs. For example, TOhtml will by default use UTF-8 for all
520Unicode/UCS encodings. To use UTF-16 and UTF-32 instead, use: >
521 :let g:html_charset_override = {'ucs-4': 'UTF-32', 'utf-16': 'UTF-16'}
522
523Note that documents encoded in either UTF-32 or UTF-16 have known
524compatibility problems with at least one major browser.

Bram Moolenaar166af9b2010-11-16 20:34:40 +0100527If you do not like plain HTML, an alternative is to have the script generate
528XHTML (XML compliant HTML). To do this set the "html_use_xhtml" variable: >

Bram Moolenaar166af9b2010-11-16 20:34:40 +0100531Any of the on/off options listed above can be enabled or disabled by setting
532them explicitly to the desired value, or restored to their default by removing
533the variable using |:unlet|.

535Remarks:
Bram Moolenaar076e8b22010-08-05 21:54:00 +0200536- Some truly ancient browsers may not show the background colors.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000537- From most browsers you can also print the file (in color)!
Bram Moolenaar166af9b2010-11-16 20:34:40 +0100538- This version of TOhtml may work with older versions of Vim, but some
539 features such as conceal support will not function, and the colors may be
540 incorrect for an old Vim without GUI support compiled in.

596Files matching "*.i" could be Progress or Assembly. If the automatic detection
597doesn't work for you, or you don't edit Progress at all, use this in your
598startup vimrc: >
599 :let filetype_i = "asm"
600Replace "asm" with the type of assembly you use.
601
602There are many types of assembly languages that all use the same file name
603extensions. Therefore you will have to select the type yourself, or add a
604line in the assembly file that Vim will recognize. Currently these syntax
605files are included:
606 asm GNU assembly (the default)
607 asm68k Motorola 680x0 assembly
608 asmh8300 Hitachi H-8300 version of GNU assembly
609 ia64 Intel Itanium 64
610 fasm Flat assembly (http://flatassembler.net)
611 masm Microsoft assembly (probably works for any 80x86)
612 nasm Netwide assembly
613 tasm Turbo Assembly (with opcodes 80x86 up to Pentium, and
614 MMX)
615 pic PIC assembly (currently for PIC16F84)
616
617The most flexible is to add a line in your assembly file containing: >
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100618 asmsyntax=nasm
Bram Moolenaar071d4272004-06-13 20:20:40 +0000619Replace "nasm" with the name of the real assembly syntax. This line must be
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +0100620one of the first five lines in the file. No non-white text must be
621immediately before or after this text.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000622
623The syntax type can always be overruled for a specific buffer by setting the
624b:asmsyntax variable: >
Bram Moolenaar8c8de832008-06-24 22:58:06 +0000625 :let b:asmsyntax = "nasm"
Bram Moolenaar071d4272004-06-13 20:20:40 +0000626
627If b:asmsyntax is not set, either automatically or by hand, then the value of
628the global variable asmsyntax is used. This can be seen as a default assembly
629language: >
Bram Moolenaar8c8de832008-06-24 22:58:06 +0000630 :let asmsyntax = "nasm"
Bram Moolenaar071d4272004-06-13 20:20:40 +0000631
632As a last resort, if nothing is defined, the "asm" syntax is used.

651*.asp and *.asa files could be either Perl or Visual Basic script. Since it's
652hard to detect this you can set two global variables to tell Vim what you are

655 :let g:filetype_asp = "aspperl"

664for both 3 GL and 4 GL programming. Large number of standard defines/constants
665are supported.

672
673Syntax folding can be enabled at various levels through the variables
674mentioned below (Set those in your |.vimrc|). The more complex folding on
675source blocks and SQL can be CPU intensive.
676
677To allow any folding and enable folding at function level use: >
678 let baan_fold=1
679Folding can be enabled at source block level as if, while, for ,... The
680indentation preceding the begin/end keywords has to match (spaces are not
681considered equal to a tab). >
682 let baan_fold_block=1

Bram Moolenaar071d4272004-06-13 20:20:40 +0000695
696Both Visual Basic and "normal" basic use the extension ".bas". To detect
697which one should be used, Vim checks for the string "VB_Name" in the first
698five lines of the file. If it is not found, filetype will be "basic",
699otherwise "vb". Files with the ".frm" extension will always be seen as Visual
700Basic.

733 :let c_no_comment_fold = 1

Bram Moolenaar071d4272004-06-13 20:20:40 +0000737If you notice highlighting errors while scrolling backwards, which are fixed
738when redrawing with CTRL-L, try setting the "c_minlines" internal variable
739to a larger number: >
740 :let c_minlines = 100
741This will make the syntax synchronization start 100 lines before the first
742displayed line. The default value is 50 (15 when c_no_if0 is set). The
743disadvantage of using a larger number is that redrawing can become slow.
744
745When using the "#if 0" / "#endif" comment highlighting, notice that this only
746works when the "#if 0" is within "c_minlines" from the top of the window. If
747you have a long "#if 0" construct it will not be highlighted correctly.
748
749To match extra items in comments, use the cCommentGroup cluster.
750Example: >
751 :au Syntax c call MyCadd()
752 :function MyCadd()
753 : syn keyword cMyItem contained Ni
754 : syn cluster cCommentGroup add=cMyItem
755 : hi link cMyItem Title
756 :endfun
757
758ANSI constants will be highlighted with the "cConstant" group. This includes
759"NULL", "SIG_IGN" and others. But not "TRUE", for example, because this is
760not in the ANSI standard. If you find this confusing, remove the cConstant
761highlighting: >
762 :hi link cConstant NONE
763
764If you see '{' and '}' highlighted as an error where they are OK, reset the
765highlighting for cErrInParen and cErrInBracket.
766
767If you want to use folding in your C files, you can add these lines in a file
Bram Moolenaar06b5d512010-05-22 15:37:44 +0200768in the "after" directory in 'runtimepath'. For Unix this would be
Bram Moolenaar071d4272004-06-13 20:20:40 +0000769~/.vim/after/syntax/c.vim. >
Bram Moolenaar071d4272004-06-13 20:20:40 +0000770 syn sync fromstart

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000773CH *ch.vim* *ft-ch-syntax*
Bram Moolenaard4755bb2004-09-02 19:12:26 +0000774
775C/C++ interpreter. Ch has similar syntax highlighting to C and builds upon
776the C syntax file. See |c.vim| for all the settings that are available for C.
777
778By setting a variable you can tell Vim to use Ch syntax for *.h files, instead
779of C or C++: >
780 :let ch_syntax_for_h = 1

Bram Moolenaar071d4272004-06-13 20:20:40 +0000784
785Chill syntax highlighting is similar to C. See |c.vim| for all the settings
786that are available. Additionally there is:
787
Bram Moolenaar071d4272004-06-13 20:20:40 +0000788chill_space_errors like c_space_errors
789chill_comment_string like c_comment_strings

792
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000793CHANGELOG *changelog.vim* *ft-changelog-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000794
795ChangeLog supports highlighting spaces at the start of a line.
796If you do not like this, add following line to your .vimrc: >
797 let g:changelog_spacing_errors = 0
798This works the next time you edit a changelog file. You can also use
799"b:changelog_spacing_errors" to set this per buffer (before loading the syntax
800file).
801
802You can change the highlighting used, e.g., to flag the spaces as an error: >
803 :hi link ChangelogError Error
804Or to avoid the highlighting: >
805 :hi link ChangelogError NONE
806This works immediately.

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000809COBOL *cobol.vim* *ft-cobol-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000810
811COBOL highlighting has different needs for legacy code than it does for fresh
812development. This is due to differences in what is being done (maintenance
813versus development) and other factors. To enable legacy code highlighting,
814add this line to your .vimrc: >
815 :let cobol_legacy_code = 1
816To disable it again, use this: >
817 :unlet cobol_legacy_code

Bram Moolenaar071d4272004-06-13 20:20:40 +0000821
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000822The ColdFusion has its own version of HTML comments. To turn on ColdFusion
Bram Moolenaar071d4272004-06-13 20:20:40 +0000823comment highlighting, add the following line to your startup file: >
824
825 :let html_wrong_comments = 1
826
827The ColdFusion syntax file is based on the HTML syntax file.
828
829
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000830CSH *csh.vim* *ft-csh-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000831
832This covers the shell named "csh". Note that on some systems tcsh is actually
833used.
834
835Detecting whether a file is csh or tcsh is notoriously hard. Some systems
836symlink /bin/csh to /bin/tcsh, making it almost impossible to distinguish
837between csh and tcsh. In case VIM guesses wrong you can set the
838"filetype_csh" variable. For using csh: >
839
840 :let filetype_csh = "csh"
841
842For using tcsh: >
843
844 :let filetype_csh = "tcsh"
845
846Any script with a tcsh extension or a standard tcsh filename (.tcshrc,
847tcsh.tcshrc, tcsh.login) will have filetype tcsh. All other tcsh/csh scripts
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000848will be classified as tcsh, UNLESS the "filetype_csh" variable exists. If the
Bram Moolenaar071d4272004-06-13 20:20:40 +0000849"filetype_csh" variable exists, the filetype will be set to the value of the
850variable.

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000853CYNLIB *cynlib.vim* *ft-cynlib-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000854
855Cynlib files are C++ files that use the Cynlib class library to enable
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000856hardware modelling and simulation using C++. Typically Cynlib files have a .cc
Bram Moolenaar071d4272004-06-13 20:20:40 +0000857or a .cpp extension, which makes it very difficult to distinguish them from a
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000858normal C++ file. Thus, to enable Cynlib highlighting for .cc files, add this
Bram Moolenaar071d4272004-06-13 20:20:40 +0000859line to your .vimrc file: >
860
861 :let cynlib_cyntax_for_cc=1
862
863Similarly for cpp files (this extension is only usually used in Windows) >
864
865 :let cynlib_cyntax_for_cpp=1
866
867To disable these again, use this: >
868
869 :unlet cynlib_cyntax_for_cc
870 :unlet cynlib_cyntax_for_cpp
871<
872
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000873CWEB *cweb.vim* *ft-cweb-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000874
875Files matching "*.w" could be Progress or cweb. If the automatic detection
876doesn't work for you, or you don't edit Progress at all, use this in your
877startup vimrc: >
878 :let filetype_w = "cweb"
879
880
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000881DESKTOP *desktop.vim* *ft-desktop-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000882
883Primary goal of this syntax file is to highlight .desktop and .directory files
Bram Moolenaara17d4c12010-05-30 18:30:36 +0200884according to freedesktop.org standard:
885http://standards.freedesktop.org/desktop-entry-spec/latest/
Bram Moolenaar071d4272004-06-13 20:20:40 +0000886But actually almost none implements this standard fully. Thus it will
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000887highlight all Unix ini files. But you can force strict highlighting according
Bram Moolenaar071d4272004-06-13 20:20:40 +0000888to standard by placing this in your vimrc file: >
889 :let enforce_freedesktop_standard = 1
890
891
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000892DIRCOLORS *dircolors.vim* *ft-dircolors-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000893
894The dircolors utility highlighting definition has one option. It exists to
895provide compatibility with the Slackware GNU/Linux distributions version of
896the command. It adds a few keywords that are generally ignored by most
897versions. On Slackware systems, however, the utility accepts the keywords and
898uses them for processing. To enable the Slackware keywords add the following
899line to your startup file: >
900 let dircolors_is_slackware = 1
901
902
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000903DOCBOOK *docbk.vim* *ft-docbk-syntax* *docbook*
904DOCBOOK XML *docbkxml.vim* *ft-docbkxml-syntax*
905DOCBOOK SGML *docbksgml.vim* *ft-docbksgml-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000906
907There are two types of DocBook files: SGML and XML. To specify what type you
908are using the "b:docbk_type" variable should be set. Vim does this for you
909automatically if it can recognize the type. When Vim can't guess it the type
910defaults to XML.
911You can set the type manually: >
912 :let docbk_type = "sgml"
913or: >
914 :let docbk_type = "xml"
915You need to do this before loading the syntax file, which is complicated.
916Simpler is setting the filetype to "docbkxml" or "docbksgml": >
917 :set filetype=docbksgml
918or: >
919 :set filetype=docbkxml
920
921
Bram Moolenaarda2303d2005-08-30 21:55:26 +0000922DOSBATCH *dosbatch.vim* *ft-dosbatch-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000923
924There is one option with highlighting DOS batch files. This covers new
925extensions to the Command Interpreter introduced with Windows 2000 and
926is controlled by the variable dosbatch_cmdextversion. For Windows NT
927this should have the value 1, and for Windows 2000 it should be 2.
928Select the version you want with the following line: >
929
Bram Moolenaar8299df92004-07-10 09:47:34 +0000930 :let dosbatch_cmdextversion = 1
Bram Moolenaar071d4272004-06-13 20:20:40 +0000931
932If this variable is not defined it defaults to a value of 2 to support
933Windows 2000.
934
Bram Moolenaar8299df92004-07-10 09:47:34 +0000935A second option covers whether *.btm files should be detected as type
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000936"dosbatch" (MS-DOS batch files) or type "btm" (4DOS batch files). The latter
937is used by default. You may select the former with the following line: >
Bram Moolenaar8299df92004-07-10 09:47:34 +0000938
939 :let g:dosbatch_syntax_for_btm = 1
940
941If this variable is undefined or zero, btm syntax is selected.
942
943
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000944DOXYGEN *doxygen.vim* *doxygen-syntax*
945
946Doxygen generates code documentation using a special documentation format
Bram Moolenaare37d50a2008-08-06 17:06:04 +0000947(similar to Javadoc). This syntax script adds doxygen highlighting to c, cpp,
948idl and php files, and should also work with java.
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000949
Bram Moolenaar25394022007-05-10 19:06:20 +0000950There are a few of ways to turn on doxygen formatting. It can be done
951explicitly or in a modeline by appending '.doxygen' to the syntax of the file.
952Example: >
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000953 :set syntax=c.doxygen
954or >
955 // vim:syntax=c.doxygen
956
Bram Moolenaar09092152010-08-08 16:38:42 +0200957It can also be done automatically for C, C++, C# and IDL files by setting the
Bram Moolenaar25394022007-05-10 19:06:20 +0000958global or buffer-local variable load_doxygen_syntax. This is done by adding
959the following to your .vimrc. >
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000960 :let g:load_doxygen_syntax=1
961
Bram Moolenaar06b5d512010-05-22 15:37:44 +0200962There are a couple of variables that have an effect on syntax highlighting, and
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000963are to do with non-standard highlighting options.
964
965Variable Default Effect ~
966g:doxygen_enhanced_color
967g:doxygen_enhanced_colour 0 Use non-standard highlighting for
968 doxygen comments.
969
970doxygen_my_rendering 0 Disable rendering of HTML bold, italic
971 and html_my_rendering underline.
972
973doxygen_javadoc_autobrief 1 Set to 0 to disable javadoc autobrief
974 colour highlighting.
975
976doxygen_end_punctuation '[.]' Set to regexp match for the ending
Bram Moolenaarc9b4b052006-04-30 18:54:39 +0000977 punctuation of brief
Bram Moolenaar8cacf352006-04-15 20:27:24 +0000978
979There are also some hilight groups worth mentioning as they can be useful in
980configuration.
981
982Highlight Effect ~
983doxygenErrorComment The colour of an end-comment when missing
984 punctuation in a code, verbatim or dot section
985doxygenLinkError The colour of an end-comment when missing the
986 \endlink from a \link section.
987

Bram Moolenaarda2303d2005-08-30 21:55:26 +0000989DTD *dtd.vim* *ft-dtd-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000990
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000991The DTD syntax highlighting is case sensitive by default. To disable
Bram Moolenaar071d4272004-06-13 20:20:40 +0000992case-sensitive highlighting, add the following line to your startup file: >
993
994 :let dtd_ignore_case=1
995
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +0000996The DTD syntax file will highlight unknown tags as errors. If
Bram Moolenaar071d4272004-06-13 20:20:40 +0000997this is annoying, it can be turned off by setting: >
998
999 :let dtd_no_tag_errors=1
1000
1001before sourcing the dtd.vim syntax file.
1002Parameter entity names are highlighted in the definition using the
1003'Type' highlighting group and 'Comment' for punctuation and '%'.
1004Parameter entity instances are highlighted using the 'Constant'
1005highlighting group and the 'Type' highlighting group for the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001006delimiters % and ;. This can be turned off by setting: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001007
1008 :let dtd_no_param_entities=1
1009
1010The DTD syntax file is also included by xml.vim to highlight included dtd's.
1011
1012
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001013EIFFEL *eiffel.vim* *ft-eiffel-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001014
1015While Eiffel is not case-sensitive, its style guidelines are, and the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001016syntax highlighting file encourages their use. This also allows to
1017highlight class names differently. If you want to disable case-sensitive
Bram Moolenaar071d4272004-06-13 20:20:40 +00001018highlighting, add the following line to your startup file: >
1019
1020 :let eiffel_ignore_case=1
1021
1022Case still matters for class names and TODO marks in comments.
1023
1024Conversely, for even stricter checks, add one of the following lines: >
1025
1026 :let eiffel_strict=1
1027 :let eiffel_pedantic=1
1028
1029Setting eiffel_strict will only catch improper capitalization for the
1030five predefined words "Current", "Void", "Result", "Precursor", and
1031"NONE", to warn against their accidental use as feature or class names.
1032
1033Setting eiffel_pedantic will enforce adherence to the Eiffel style
1034guidelines fairly rigorously (like arbitrary mixes of upper- and
1035lowercase letters as well as outdated ways to capitalize keywords).
1036
1037If you want to use the lower-case version of "Current", "Void",
1038"Result", and "Precursor", you can use >
1039
1040 :let eiffel_lower_case_predef=1
1041
1042instead of completely turning case-sensitive highlighting off.
1043
1044Support for ISE's proposed new creation syntax that is already
1045experimentally handled by some compilers can be enabled by: >
1046
1047 :let eiffel_ise=1
1048
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001049Finally, some vendors support hexadecimal constants. To handle them, add >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001050
1051 :let eiffel_hex_constants=1
1052
1053to your startup file.

Bram Moolenaar071d4272004-06-13 20:20:40 +00001057
1058The erlang highlighting supports Erlang (ERicsson LANGuage).
1059Erlang is case sensitive and default extension is ".erl".
1060
1061If you want to disable keywords highlighting, put in your .vimrc: >
1062 :let erlang_keywords = 1
1063If you want to disable built-in-functions highlighting, put in your
1064.vimrc file: >
1065 :let erlang_functions = 1
1066If you want to disable special characters highlighting, put in
1067your .vimrc: >

Bram Moolenaard68071d2006-05-02 22:08:30 +00001071FLEXWIKI *flexwiki.vim* *ft-flexwiki-syntax*
1072
1073FlexWiki is an ASP.NET-based wiki package available at http://www.flexwiki.com
1074
1075Syntax highlighting is available for the most common elements of FlexWiki
1076syntax. The associated ftplugin script sets some buffer-local options to make
1077editing FlexWiki pages more convenient. FlexWiki considers a newline as the
1078start of a new paragraph, so the ftplugin sets 'tw'=0 (unlimited line length),
1079'wrap' (wrap long lines instead of using horizontal scrolling), 'linebreak'
1080(to wrap at a character in 'breakat' instead of at the last char on screen),
1081and so on. It also includes some keymaps that are disabled by default.
1082
1083If you want to enable the keymaps that make "j" and "k" and the cursor keys
1084move up and down by display lines, add this to your .vimrc: >
1085 :let flexwiki_maps = 1

1087
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001088FORM *form.vim* *ft-form-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001089
1090The coloring scheme for syntax elements in the FORM file uses the default
1091modes Conditional, Number, Statement, Comment, PreProc, Type, and String,
Bram Moolenaardd2a0d82007-05-12 15:07:00 +00001092following the language specifications in 'Symbolic Manipulation with FORM' by
Bram Moolenaar071d4272004-06-13 20:20:40 +00001093J.A.M. Vermaseren, CAN, Netherlands, 1991.
1094
1095If you want include your own changes to the default colors, you have to
1096redefine the following syntax groups:
1097
1098 - formConditional
1099 - formNumber
1100 - formStatement
1101 - formHeaderStatement
1102 - formComment
1103 - formPreProc
1104 - formDirective
1105 - formType
1106 - formString
1107
1108Note that the form.vim syntax file implements FORM preprocessor commands and
1109directives per default in the same syntax group.
1110
1111A predefined enhanced color mode for FORM is available to distinguish between
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001112header statements and statements in the body of a FORM program. To activate
Bram Moolenaar071d4272004-06-13 20:20:40 +00001113this mode define the following variable in your vimrc file >
1114
1115 :let form_enhanced_color=1
1116
1117The enhanced mode also takes advantage of additional color features for a dark
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001118gvim display. Here, statements are colored LightYellow instead of Yellow, and
Bram Moolenaar071d4272004-06-13 20:20:40 +00001119conditionals are LightBlue for better distinction.
1120

1124Default highlighting and dialect ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001125Highlighting appropriate for f95 (Fortran 95) is used by default. This choice
Bram Moolenaar071d4272004-06-13 20:20:40 +00001126should be appropriate for most users most of the time because Fortran 95 is a
Bram Moolenaar365bdf72010-07-24 20:57:44 +02001127superset of Fortran 90 and almost a superset of Fortran 77. Support for
1128Fortran 2003 and Fortran 2008 features has been introduced and is
Bram Moolenaare06c1882010-07-21 22:05:20 +02001129automatically available in the default (f95) highlighting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001130
1131Fortran source code form ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001132Fortran 9x code can be in either fixed or free source form. Note that the
Bram Moolenaar071d4272004-06-13 20:20:40 +00001133syntax highlighting will not be correct if the form is incorrectly set.
1134
1135When you create a new fortran file, the syntax script assumes fixed source
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001136form. If you always use free source form, then >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001137 :let fortran_free_source=1
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001138in your .vimrc prior to the :syntax on command. If you always use fixed source
Bram Moolenaar071d4272004-06-13 20:20:40 +00001139form, then >
1140 :let fortran_fixed_source=1
1141in your .vimrc prior to the :syntax on command.
1142
1143If the form of the source code depends upon the file extension, then it is
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001144most convenient to set fortran_free_source in a ftplugin file. For more
1145information on ftplugin files, see |ftplugin|. For example, if all your
Bram Moolenaar071d4272004-06-13 20:20:40 +00001146fortran files with an .f90 extension are written in free source form and the
1147rest in fixed source form, add the following code to your ftplugin file >
1148 let s:extfname = expand("%:e")
1149 if s:extfname ==? "f90"
1150 let fortran_free_source=1
1151 unlet! fortran_fixed_source
1152 else
1153 let fortran_fixed_source=1
1154 unlet! fortran_free_source
1155 endif
1156Note that this will work only if the "filetype plugin indent on" command
1157precedes the "syntax on" command in your .vimrc file.
1158
1159When you edit an existing fortran file, the syntax script will assume free
1160source form if the fortran_free_source variable has been set, and assumes
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001161fixed source form if the fortran_fixed_source variable has been set. If
Bram Moolenaar071d4272004-06-13 20:20:40 +00001162neither of these variables have been set, the syntax script attempts to
1163determine which source form has been used by examining the first five columns
Bram Moolenaar910f66f2006-04-05 20:41:53 +00001164of the first 250 lines of your file. If no signs of free source form are
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001165detected, then the file is assumed to be in fixed source form. The algorithm
1166should work in the vast majority of cases. In some cases, such as a file that
Bram Moolenaar910f66f2006-04-05 20:41:53 +00001167begins with 250 or more full-line comments, the script may incorrectly decide
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001168that the fortran code is in fixed form. If that happens, just add a
Bram Moolenaar071d4272004-06-13 20:20:40 +00001169non-comment statement beginning anywhere in the first five columns of the
1170first twenty five lines, save (:w) and then reload (:e!) the file.
1171
1172Tabs in fortran files ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001173Tabs are not recognized by the Fortran standards. Tabs are not a good idea in
Bram Moolenaar071d4272004-06-13 20:20:40 +00001174fixed format fortran source code which requires fixed column boundaries.
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001175Therefore, tabs are marked as errors. Nevertheless, some programmers like
1176using tabs. If your fortran files contain tabs, then you should set the
Bram Moolenaar071d4272004-06-13 20:20:40 +00001177variable fortran_have_tabs in your .vimrc with a command such as >
1178 :let fortran_have_tabs=1
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001179placed prior to the :syntax on command. Unfortunately, the use of tabs will
Bram Moolenaar071d4272004-06-13 20:20:40 +00001180mean that the syntax file will not be able to detect incorrect margins.
1181
1182Syntax folding of fortran files ~
1183If you wish to use foldmethod=syntax, then you must first set the variable
1184fortran_fold with a command such as >
1185 :let fortran_fold=1
1186to instruct the syntax script to define fold regions for program units, that
1187is main programs starting with a program statement, subroutines, function
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001188subprograms, block data subprograms, interface blocks, and modules. If you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001189also set the variable fortran_fold_conditionals with a command such as >
1190 :let fortran_fold_conditionals=1
1191then fold regions will also be defined for do loops, if blocks, and select
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001192case constructs. If you also set the variable
Bram Moolenaar071d4272004-06-13 20:20:40 +00001193fortran_fold_multilinecomments with a command such as >
1194 :let fortran_fold_multilinecomments=1
1195then fold regions will also be defined for three or more consecutive comment
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001196lines. Note that defining fold regions can be slow for large files.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001197
1198If fortran_fold, and possibly fortran_fold_conditionals and/or
1199fortran_fold_multilinecomments, have been set, then vim will fold your file if
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001200you set foldmethod=syntax. Comments or blank lines placed between two program
Bram Moolenaar071d4272004-06-13 20:20:40 +00001201units are not folded because they are seen as not belonging to any program
1202unit.
1203
1204More precise fortran syntax ~
1205If you set the variable fortran_more_precise with a command such as >
1206 :let fortran_more_precise=1
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001207then the syntax coloring will be more precise but slower. In particular,
Bram Moolenaar071d4272004-06-13 20:20:40 +00001208statement labels used in do, goto and arithmetic if statements will be
1209recognized, as will construct names at the end of a do, if, select or forall
1210construct.
1211
1212Non-default fortran dialects ~
1213The syntax script supports five Fortran dialects: f95, f90, f77, the Lahey
1214subset elf90, and the Imagine1 subset F.
1215
1216If you use f77 with extensions, even common ones like do/enddo loops, do/while
1217loops and free source form that are supported by most f77 compilers including
1218g77 (GNU Fortran), then you will probably find the default highlighting
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001219satisfactory. However, if you use strict f77 with no extensions, not even free
Bram Moolenaar071d4272004-06-13 20:20:40 +00001220source form or the MIL STD 1753 extensions, then the advantages of setting the
1221dialect to f77 are that names such as SUM are recognized as user variable
1222names and not highlighted as f9x intrinsic functions, that obsolete constructs
1223such as ASSIGN statements are not highlighted as todo items, and that fixed
1224source form will be assumed.
1225
1226If you use elf90 or F, the advantage of setting the dialect appropriately is
1227that f90 features excluded from these dialects will be highlighted as todo
1228items and that free source form will be assumed as required for these
1229dialects.
1230
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001231The dialect can be selected by setting the variable fortran_dialect. The
Bram Moolenaar071d4272004-06-13 20:20:40 +00001232permissible values of fortran_dialect are case-sensitive and must be "f95",
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001233"f90", "f77", "elf" or "F". Invalid values of fortran_dialect are ignored.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001234
1235If all your fortran files use the same dialect, set fortran_dialect in your
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001236.vimrc prior to your syntax on statement. If the dialect depends upon the file
1237extension, then it is most convenient to set it in a ftplugin file. For more
1238information on ftplugin files, see |ftplugin|. For example, if all your
Bram Moolenaar071d4272004-06-13 20:20:40 +00001239fortran files with an .f90 extension are written in the elf subset, your
1240ftplugin file should contain the code >
1241 let s:extfname = expand("%:e")
1242 if s:extfname ==? "f90"
1243 let fortran_dialect="elf"
1244 else
1245 unlet! fortran_dialect
1246 endif
1247Note that this will work only if the "filetype plugin indent on" command
1248precedes the "syntax on" command in your .vimrc file.
1249
1250Finer control is necessary if the file extension does not uniquely identify
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001251the dialect. You can override the default dialect, on a file-by-file basis, by
Bram Moolenaar071d4272004-06-13 20:20:40 +00001252including a comment with the directive "fortran_dialect=xx" (where xx=f77 or
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001253elf or F or f90 or f95) in one of the first three lines in your file. For
Bram Moolenaar071d4272004-06-13 20:20:40 +00001254example, your older .f files may be written in extended f77 but your newer
1255ones may be F codes, and you would identify the latter by including in the
1256first three lines of those files a Fortran comment of the form >
1257 ! fortran_dialect=F
1258F overrides elf if both directives are present.
1259
1260Limitations ~
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001261Parenthesis checking does not catch too few closing parentheses. Hollerith
1262strings are not recognized. Some keywords may be highlighted incorrectly
Bram Moolenaar071d4272004-06-13 20:20:40 +00001263because Fortran90 has no reserved words.
1264
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001265For further information related to fortran, see |ft-fortran-indent| and
1266|ft-fortran-plugin|.

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001269FVWM CONFIGURATION FILES *fvwm.vim* *ft-fvwm-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001270
1271In order for Vim to recognize Fvwm configuration files that do not match
1272the patterns *fvwmrc* or *fvwm2rc* , you must put additional patterns
1273appropriate to your system in your myfiletypes.vim file. For these
1274patterns, you must set the variable "b:fvwm_version" to the major version
1275number of Fvwm, and the 'filetype' option to fvwm.
1276
1277For example, to make Vim identify all files in /etc/X11/fvwm2/
1278as Fvwm2 configuration files, add the following: >
1279
1280 :au! BufNewFile,BufRead /etc/X11/fvwm2/* let b:fvwm_version = 2 |
1281 \ set filetype=fvwm
1282
1283If you'd like Vim to highlight all valid color names, tell it where to
1284find the color database (rgb.txt) on your system. Do this by setting
1285"rgb_file" to its location. Assuming your color database is located
1286in /usr/X11/lib/X11/, you should add the line >
1287
1288 :let rgb_file = "/usr/X11/lib/X11/rgb.txt"
1289
1290to your .vimrc file.
1291
1292
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001293GSP *gsp.vim* *ft-gsp-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001294
1295The default coloring style for GSP pages is defined by |html.vim|, and
1296the coloring for java code (within java tags or inline between backticks)
1297is defined by |java.vim|. The following HTML groups defined in |html.vim|
1298are redefined to incorporate and highlight inline java code:
1299
1300 htmlString
1301 htmlValue
1302 htmlEndTag
1303 htmlTag
1304 htmlTagN
1305
1306Highlighting should look fine most of the places where you'd see inline
1307java code, but in some special cases it may not. To add another HTML
1308group where you will have inline java code where it does not highlight
1309correctly, just copy the line you want from |html.vim| and add gspJava
1310to the contains clause.
1311
1312The backticks for inline java are highlighted according to the htmlError
1313group to make them easier to see.
1314
1315
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001316GROFF *groff.vim* *ft-groff-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001317
1318The groff syntax file is a wrapper for |nroff.vim|, see the notes
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001319under that heading for examples of use and configuration. The purpose
Bram Moolenaar071d4272004-06-13 20:20:40 +00001320of this wrapper is to set up groff syntax extensions by setting the
1321filetype from a |modeline| or in a personal filetype definitions file
1322(see |filetype.txt|).
1323
1324
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001325HASKELL *haskell.vim* *lhaskell.vim* *ft-haskell-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001326
1327The Haskell syntax files support plain Haskell code as well as literate
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001328Haskell code, the latter in both Bird style and TeX style. The Haskell
Bram Moolenaar071d4272004-06-13 20:20:40 +00001329syntax highlighting will also highlight C preprocessor directives.
1330
1331If you want to highlight delimiter characters (useful if you have a
1332light-coloured background), add to your .vimrc: >
1333 :let hs_highlight_delimiters = 1
1334To treat True and False as keywords as opposed to ordinary identifiers,
1335add: >
1336 :let hs_highlight_boolean = 1
1337To also treat the names of primitive types as keywords: >
1338 :let hs_highlight_types = 1
1339And to treat the names of even more relatively common types as keywords: >
1340 :let hs_highlight_more_types = 1
1341If you want to highlight the names of debugging functions, put in
1342your .vimrc: >
1343 :let hs_highlight_debug = 1
1344
1345The Haskell syntax highlighting also highlights C preprocessor
1346directives, and flags lines that start with # but are not valid
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001347directives as erroneous. This interferes with Haskell's syntax for
1348operators, as they may start with #. If you want to highlight those
Bram Moolenaar071d4272004-06-13 20:20:40 +00001349as operators as opposed to errors, put in your .vimrc: >
1350 :let hs_allow_hash_operator = 1
1351
1352The syntax highlighting for literate Haskell code will try to
1353automatically guess whether your literate Haskell code contains
1354TeX markup or not, and correspondingly highlight TeX constructs
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001355or nothing at all. You can override this globally by putting
Bram Moolenaar071d4272004-06-13 20:20:40 +00001356in your .vimrc >
1357 :let lhs_markup = none
1358for no highlighting at all, or >
1359 :let lhs_markup = tex
1360to force the highlighting to always try to highlight TeX markup.
1361For more flexibility, you may also use buffer local versions of
1362this variable, so e.g. >
1363 :let b:lhs_markup = tex
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001364will force TeX highlighting for a particular buffer. It has to be
Bram Moolenaar071d4272004-06-13 20:20:40 +00001365set before turning syntax highlighting on for the buffer or
1366loading a file.
1367
1368
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001369HTML *html.vim* *ft-html-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001370
1371The coloring scheme for tags in the HTML file works as follows.
1372
1373The <> of opening tags are colored differently than the </> of a closing tag.
1374This is on purpose! For opening tags the 'Function' color is used, while for
1375closing tags the 'Type' color is used (See syntax.vim to check how those are
1376defined for you)
1377
1378Known tag names are colored the same way as statements in C. Unknown tag
1379names are colored with the same color as the <> or </> respectively which
1380makes it easy to spot errors
1381
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001382Note that the same is true for argument (or attribute) names. Known attribute
Bram Moolenaar071d4272004-06-13 20:20:40 +00001383names are colored differently than unknown ones.
1384
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001385Some HTML tags are used to change the rendering of text. The following tags
Bram Moolenaar071d4272004-06-13 20:20:40 +00001386are recognized by the html.vim syntax coloring file and change the way normal
1387text is shown: <B> <I> <U> <EM> <STRONG> (<EM> is used as an alias for <I>,
1388while <STRONG> as an alias for <B>), <H1> - <H6>, <HEAD>, <TITLE> and <A>, but
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001389only if used as a link (that is, it must include a href as in
Bram Moolenaar25394022007-05-10 19:06:20 +00001390<A href="somefile.html">).
Bram Moolenaar071d4272004-06-13 20:20:40 +00001391
1392If you want to change how such text is rendered, you must redefine the
1393following syntax groups:
1394
1395 - htmlBold
1396 - htmlBoldUnderline
1397 - htmlBoldUnderlineItalic
1398 - htmlUnderline
1399 - htmlUnderlineItalic
1400 - htmlItalic
1401 - htmlTitle for titles
1402 - htmlH1 - htmlH6 for headings
1403
1404To make this redefinition work you must redefine them all with the exception
1405of the last two (htmlTitle and htmlH[1-6], which are optional) and define the
1406following variable in your vimrc (this is due to the order in which the files
1407are read during initialization) >
1408 :let html_my_rendering=1
1409
1410If you'd like to see an example download mysyntax.vim at
1411http://www.fleiner.com/vim/download.html
1412
1413You can also disable this rendering by adding the following line to your
1414vimrc file: >
1415 :let html_no_rendering=1
1416
1417HTML comments are rather special (see an HTML reference document for the
1418details), and the syntax coloring scheme will highlight all errors.
1419However, if you prefer to use the wrong style (starts with <!-- and
1420ends with --!>) you can define >
1421 :let html_wrong_comments=1
1422
1423JavaScript and Visual Basic embedded inside HTML documents are highlighted as
1424'Special' with statements, comments, strings and so on colored as in standard
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001425programming languages. Note that only JavaScript and Visual Basic are currently
Bram Moolenaar071d4272004-06-13 20:20:40 +00001426supported, no other scripting language has been added yet.
1427
1428Embedded and inlined cascading style sheets (CSS) are highlighted too.
1429
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001430There are several html preprocessor languages out there. html.vim has been
1431written such that it should be trivial to include it. To do so add the
Bram Moolenaar071d4272004-06-13 20:20:40 +00001432following two lines to the syntax coloring file for that language
1433(the example comes from the asp.vim file):
1434
1435 runtime! syntax/html.vim
1436 syn cluster htmlPreproc add=asp
1437
1438Now you just need to make sure that you add all regions that contain
1439the preprocessor language to the cluster htmlPreproc.
1440

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001442HTML/OS (by Aestiva) *htmlos.vim* *ft-htmlos-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001443
1444The coloring scheme for HTML/OS works as follows:
1445
1446Functions and variable names are the same color by default, because VIM
1447doesn't specify different colors for Functions and Identifiers. To change
1448this (which is recommended if you want function names to be recognizable in a
1449different color) you need to add the following line to either your ~/.vimrc: >
1450 :hi Function term=underline cterm=bold ctermfg=LightGray
1451
1452Of course, the ctermfg can be a different color if you choose.
1453
1454Another issues that HTML/OS runs into is that there is no special filetype to
1455signify that it is a file with HTML/OS coding. You can change this by opening
1456a file and turning on HTML/OS syntax by doing the following: >
1457 :set syntax=htmlos
1458
1459Lastly, it should be noted that the opening and closing characters to begin a
1460block of HTML/OS code can either be << or [[ and >> or ]], respectively.
1461

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001463IA64 *ia64.vim* *intel-itanium* *ft-ia64-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001464
1465Highlighting for the Intel Itanium 64 assembly language. See |asm.vim| for
1466how to recognize this filetype.
1467
1468To have *.inc files be recognized as IA64, add this to your .vimrc file: >
1469 :let g:filetype_inc = "ia64"
1470
1471
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001472INFORM *inform.vim* *ft-inform-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001473
1474Inform highlighting includes symbols provided by the Inform Library, as
1475most programs make extensive use of it. If do not wish Library symbols
1476to be highlighted add this to your vim startup: >
1477 :let inform_highlight_simple=1
1478
1479By default it is assumed that Inform programs are Z-machine targeted,
1480and highlights Z-machine assembly language symbols appropriately. If
1481you intend your program to be targeted to a Glulx/Glk environment you
1482need to add this to your startup sequence: >
1483 :let inform_highlight_glulx=1
1484
1485This will highlight Glulx opcodes instead, and also adds glk() to the
1486set of highlighted system functions.
1487
1488The Inform compiler will flag certain obsolete keywords as errors when
1489it encounters them. These keywords are normally highlighted as errors
1490by Vim. To prevent such error highlighting, you must add this to your
1491startup sequence: >
1492 :let inform_suppress_obsolete=1
1493
1494By default, the language features highlighted conform to Compiler
1495version 6.30 and Library version 6.11. If you are using an older
1496Inform development environment, you may with to add this to your
1497startup sequence: >
1498 :let inform_highlight_old=1

Bram Moolenaar9e54a0e2006-04-14 20:42:25 +00001500IDL *idl.vim* *idl-syntax*
1501
1502IDL (Interface Definition Language) files are used to define RPC calls. In
1503Microsoft land, this is also used for defining COM interfaces and calls.
1504
1505IDL's structure is simple enough to permit a full grammar based approach to
1506rather than using a few heuristics. The result is large and somewhat
Bram Moolenaar25394022007-05-10 19:06:20 +00001507repetitive but seems to work.
Bram Moolenaar9e54a0e2006-04-14 20:42:25 +00001508
1509There are some Microsoft extensions to idl files that are here. Some of them
1510are disabled by defining idl_no_ms_extensions.
1511
1512The more complex of the extensions are disabled by defining idl_no_extensions.
1513
1514Variable Effect ~
1515
1516idl_no_ms_extensions Disable some of the Microsoft specific
1517 extensions
1518idl_no_extensions Disable complex extensions

1520 quite helpful)

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001524JAVA *java.vim* *ft-java-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001525
1526The java.vim syntax highlighting file offers several options:
1527
1528In Java 1.0.2 it was never possible to have braces inside parens, so this was
1529flagged as an error. Since Java 1.1 this is possible (with anonymous
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001530classes), and therefore is no longer marked as an error. If you prefer the old
Bram Moolenaar071d4272004-06-13 20:20:40 +00001531way, put the following line into your vim startup file: >
1532 :let java_mark_braces_in_parens_as_errors=1
1533
1534All identifiers in java.lang.* are always visible in all classes. To
1535highlight them use: >
1536 :let java_highlight_java_lang_ids=1
1537
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001538You can also highlight identifiers of most standard Java packages if you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001539download the javaid.vim script at http://www.fleiner.com/vim/download.html.
1540If you prefer to only highlight identifiers of a certain package, say java.io
1541use the following: >
1542 :let java_highlight_java_io=1
1543Check the javaid.vim file for a list of all the packages that are supported.
1544
1545Function names are not highlighted, as the way to find functions depends on
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001546how you write Java code. The syntax file knows two possible ways to highlight
Bram Moolenaar071d4272004-06-13 20:20:40 +00001547functions:
1548
1549If you write function declarations that are always indented by either
1550a tab, 8 spaces or 2 spaces you may want to set >
1551 :let java_highlight_functions="indent"
1552However, if you follow the Java guidelines about how functions and classes are
1553supposed to be named (with respect to upper and lowercase), use >
1554 :let java_highlight_functions="style"
1555If both options do not work for you, but you would still want function
1556declarations to be highlighted create your own definitions by changing the
1557definitions in java.vim or by creating your own java.vim which includes the
1558original one and then adds the code to highlight functions.
1559
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001560In Java 1.1 the functions System.out.println() and System.err.println() should
Bram Moolenaared203462004-06-16 11:19:22 +00001561only be used for debugging. Therefore it is possible to highlight debugging
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001562statements differently. To do this you must add the following definition in
Bram Moolenaar071d4272004-06-13 20:20:40 +00001563your startup file: >
1564 :let java_highlight_debug=1
1565The result will be that those statements are highlighted as 'Special'
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001566characters. If you prefer to have them highlighted differently you must define
Bram Moolenaar071d4272004-06-13 20:20:40 +00001567new highlightings for the following groups.:
1568 Debug, DebugSpecial, DebugString, DebugBoolean, DebugType
1569which are used for the statement itself, special characters used in debug
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001570strings, strings, boolean constants and types (this, super) respectively. I
Bram Moolenaar071d4272004-06-13 20:20:40 +00001571have opted to chose another background for those statements.
1572
Bram Moolenaar8c8de832008-06-24 22:58:06 +00001573In order to help you write code that can be easily ported between Java and
1574C++, all C++ keywords can be marked as an error in a Java program. To
1575have this add this line in your .vimrc file: >
1576 :let java_allow_cpp_keywords = 0
Bram Moolenaar071d4272004-06-13 20:20:40 +00001577
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001578Javadoc is a program that takes special comments out of Java program files and
1579creates HTML pages. The standard configuration will highlight this HTML code
1580similarly to HTML files (see |html.vim|). You can even add Javascript
1581and CSS inside this code (see below). There are four differences however:
Bram Moolenaar071d4272004-06-13 20:20:40 +00001582 1. The title (all characters up to the first '.' which is followed by
1583 some white space or up to the first '@') is colored differently (to change
1584 the color change the group CommentTitle).
1585 2. The text is colored as 'Comment'.
1586 3. HTML comments are colored as 'Special'
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001587 4. The special Javadoc tags (@see, @param, ...) are highlighted as specials
Bram Moolenaar071d4272004-06-13 20:20:40 +00001588 and the argument (for @see, @param, @exception) as Function.
1589To turn this feature off add the following line to your startup file: >
1590 :let java_ignore_javadoc=1
1591
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001592If you use the special Javadoc comment highlighting described above you
1593can also turn on special highlighting for Javascript, visual basic
1594scripts and embedded CSS (stylesheets). This makes only sense if you
1595actually have Javadoc comments that include either Javascript or embedded
1596CSS. The options to use are >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001597 :let java_javascript=1
1598 :let java_css=1
1599 :let java_vb=1
1600
1601In order to highlight nested parens with different colors define colors
1602for javaParen, javaParen1 and javaParen2, for example with >
1603 :hi link javaParen Comment
1604or >
1605 :hi javaParen ctermfg=blue guifg=#0000ff
1606
1607If you notice highlighting errors while scrolling backwards, which are fixed
1608when redrawing with CTRL-L, try setting the "java_minlines" internal variable
1609to a larger number: >
1610 :let java_minlines = 50
1611This will make the syntax synchronization start 50 lines before the first
1612displayed line. The default value is 10. The disadvantage of using a larger
1613number is that redrawing can become slow.
1614
1615
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001616LACE *lace.vim* *ft-lace-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001617
1618Lace (Language for Assembly of Classes in Eiffel) is case insensitive, but the
1619style guide lines are not. If you prefer case insensitive highlighting, just
1620define the vim variable 'lace_case_insensitive' in your startup file: >
1621 :let lace_case_insensitive=1
1622
1623
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001624LEX *lex.vim* *ft-lex-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001625
1626Lex uses brute-force synchronizing as the "^%%$" section delimiter
1627gives no clue as to what section follows. Consequently, the value for >
1628 :syn sync minlines=300
1629may be changed by the user if s/he is experiencing synchronization
1630difficulties (such as may happen with large lex files).

Bram Moolenaar6fc45b52010-07-25 17:42:45 +02001633LIFELINES *lifelines.vim* *ft-lifelines-syntax*
1634
1635To highlight deprecated functions as errors, add in your .vimrc: >
1636
1637 :let g:lifelines_deprecated = 1
1638<
1639
Bram Moolenaara5fac542005-10-12 20:58:49 +00001640LISP *lisp.vim* *ft-lisp-syntax*
1641
1642The lisp syntax highlighting provides two options: >
1643
1644 g:lisp_instring : if it exists, then "(...)" strings are highlighted
1645 as if the contents of the string were lisp.
1646 Useful for AutoLisp.
1647 g:lisp_rainbow : if it exists and is nonzero, then differing levels
1648 of parenthesization will receive different
1649 highlighting.
1650<
1651The g:lisp_rainbow option provides 10 levels of individual colorization for
1652the parentheses and backquoted parentheses. Because of the quantity of
1653colorization levels, unlike non-rainbow highlighting, the rainbow mode
1654specifies its highlighting using ctermfg and guifg, thereby bypassing the
1655usual colorscheme control using standard highlighting groups. The actual
1656highlighting used depends on the dark/bright setting (see |'bg'|).
1657
1658
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001659LITE *lite.vim* *ft-lite-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001660
1661There are two options for the lite syntax highlighting.
1662
1663If you like SQL syntax highlighting inside Strings, use this: >
1664
1665 :let lite_sql_query = 1
1666
1667For syncing, minlines defaults to 100. If you prefer another value, you can
1668set "lite_minlines" to the value you desire. Example: >
1669
1670 :let lite_minlines = 200
1671

Bram Moolenaarda2303d2005-08-30 21:55:26 +00001673LPC *lpc.vim* *ft-lpc-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001674
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001675LPC stands for a simple, memory-efficient language: Lars Pensj| C. The
Bram Moolenaar071d4272004-06-13 20:20:40 +00001676file name of LPC is usually *.c. Recognizing these files as LPC would bother
1677users writing only C programs. If you want to use LPC syntax in Vim, you
1678should set a variable in your .vimrc file: >
1679
1680 :let lpc_syntax_for_c = 1
1681
1682If it doesn't work properly for some particular C or LPC files, use a
1683modeline. For a LPC file:
1684
1685 // vim:set ft=lpc:
1686
1687For a C file that is recognized as LPC:
1688
1689 // vim:set ft=c:
1690
1691If you don't want to set the variable, use the modeline in EVERY LPC file.
1692
1693There are several implementations for LPC, we intend to support most widely
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001694used ones. Here the default LPC syntax is for MudOS series, for MudOS v22
Bram Moolenaar071d4272004-06-13 20:20:40 +00001695and before, you should turn off the sensible modifiers, and this will also
1696asserts the new efuns after v22 to be invalid, don't set this variable when
1697you are using the latest version of MudOS: >
1698
1699 :let lpc_pre_v22 = 1
1700
1701For LpMud 3.2 series of LPC: >
1702
1703 :let lpc_compat_32 = 1
1704
1705For LPC4 series of LPC: >
1706
1707 :let lpc_use_lpc4_syntax = 1
1708
1709For uLPC series of LPC:
1710uLPC has been developed to Pike, so you should use Pike syntax
1711instead, and the name of your source file should be *.pike

Bram Moolenaarfc1421e2006-04-20 22:17:20 +00001716This syntax file may be used for Lua 4.0, Lua 5.0 or Lua 5.1 (the latter is
1717the default). You can select one of these versions using the global variables
1718lua_version and lua_subversion. For example, to activate Lua
17194.0 syntax highlighting, use this command: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001720
1721 :let lua_version = 4
1722

Bram Moolenaar071d4272004-06-13 20:20:40 +00001735
1736Vim highlights all the standard elements of an email (headers, signatures,
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001737quoted text and URLs / email addresses). In keeping with standard conventions,
Bram Moolenaar071d4272004-06-13 20:20:40 +00001738signatures begin in a line containing only "--" followed optionally by
1739whitespaces and end with a newline.
1740
1741Vim treats lines beginning with ']', '}', '|', '>' or a word followed by '>'
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001742as quoted text. However Vim highlights headers and signatures in quoted text
Bram Moolenaar071d4272004-06-13 20:20:40 +00001743only if the text is quoted with '>' (optionally followed by one space).
1744
1745By default mail.vim synchronises syntax to 100 lines before the first
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001746displayed line. If you have a slow machine, and generally deal with emails
Bram Moolenaar071d4272004-06-13 20:20:40 +00001747with short headers, you can change this to a smaller value: >

1764supports many packages of functions which are selectively loaded by the user.
1765The standard set of packages' functions as supplied in Maple V release 4 may be

Bram Moolenaar071d4272004-06-13 20:20:40 +00001831
1832There are two options for the msql syntax highlighting.
1833
1834If you like SQL syntax highlighting inside Strings, use this: >
1835
1836 :let msql_sql_query = 1
1837
1838For syncing, minlines defaults to 100. If you prefer another value, you can
1839set "msql_minlines" to the value you desire. Example: >
1840
1841 :let msql_minlines = 200

1843
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001844NCF *ncf.vim* *ft-ncf-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001845
1846There is one option for NCF syntax highlighting.
1847
1848If you want to have unrecognized (by ncf.vim) statements highlighted as
1849errors, use this: >
1850
1851 :let ncf_highlight_unknowns = 1
1852
1853If you don't want to highlight these errors, leave it unset.
1854
1855
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001856NROFF *nroff.vim* *ft-nroff-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001857
1858The nroff syntax file works with AT&T n/troff out of the box. You need to
1859activate the GNU groff extra features included in the syntax file before you
1860can use them.
1861
1862For example, Linux and BSD distributions use groff as their default text
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001863processing package. In order to activate the extra syntax highlighting
Bram Moolenaar071d4272004-06-13 20:20:40 +00001864features for groff, add the following option to your start-up files: >
1865
1866 :let b:nroff_is_groff = 1
1867
1868Groff is different from the old AT&T n/troff that you may still find in
1869Solaris. Groff macro and request names can be longer than 2 characters and
1870there are extensions to the language primitives. For example, in AT&T troff
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001871you access the year as a 2-digit number with the request \(yr. In groff you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001872can use the same request, recognized for compatibility, or you can use groff's
1873native syntax, \[yr]. Furthermore, you can use a 4-digit year directly:
1874\[year]. Macro requests can be longer than 2 characters, for example, GNU mm
1875accepts the requests ".VERBON" and ".VERBOFF" for creating verbatim
1876environments.
1877
1878In order to obtain the best formatted output g/troff can give you, you should
1879follow a few simple rules about spacing and punctuation.
1880
18811. Do not leave empty spaces at the end of lines.
1882
18832. Leave one space and one space only after an end-of-sentence period,
1884 exclamation mark, etc.
1885
18863. For reasons stated below, it is best to follow all period marks with a
1887 carriage return.
1888
1889The reason behind these unusual tips is that g/n/troff have a line breaking
1890algorithm that can be easily upset if you don't follow the rules given above.
1891
1892Unlike TeX, troff fills text line-by-line, not paragraph-by-paragraph and,
1893furthermore, it does not have a concept of glue or stretch, all horizontal and
1894vertical space input will be output as is.
1895
1896Therefore, you should be careful about not using more space between sentences
1897than you intend to have in your final document. For this reason, the common
1898practice is to insert a carriage return immediately after all punctuation
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001899marks. If you want to have "even" text in your final processed output, you
Bram Moolenaar071d4272004-06-13 20:20:40 +00001900need to maintaining regular spacing in the input text. To mark both trailing
1901spaces and two or more spaces after a punctuation as an error, use: >
1902
1903 :let nroff_space_errors = 1
1904
1905Another technique to detect extra spacing and other errors that will interfere
1906with the correct typesetting of your file, is to define an eye-catching
1907highlighting definition for the syntax groups "nroffDefinition" and
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001908"nroffDefSpecial" in your configuration files. For example: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00001909
1910 hi def nroffDefinition term=italic cterm=italic gui=reverse
1911 hi def nroffDefSpecial term=italic,bold cterm=italic,bold
1912 \ gui=reverse,bold
1913
1914If you want to navigate preprocessor entries in your source file as easily as
1915with section markers, you can activate the following option in your .vimrc
1916file: >
1917
1918 let b:preprocs_as_sections = 1
1919
Bram Moolenaar69a7cb42004-06-20 12:51:53 +00001920As well, the syntax file adds an extra paragraph marker for the extended
Bram Moolenaar071d4272004-06-13 20:20:40 +00001921paragraph macro (.XP) in the ms package.
1922
1923Finally, there is a |groff.vim| syntax file that can be used for enabling
1924groff syntax highlighting either on a file basis or globally by default.
1925
1926
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001927OCAML *ocaml.vim* *ft-ocaml-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001928
1929The OCaml syntax file handles files having the following prefixes: .ml,
1930.mli, .mll and .mly. By setting the following variable >
1931
1932 :let ocaml_revised = 1
1933
1934you can switch from standard OCaml-syntax to revised syntax as supported
1935by the camlp4 preprocessor. Setting the variable >
1936
1937 :let ocaml_noend_error = 1
1938
1939prevents highlighting of "end" as error, which is useful when sources
1940contain very long structures that Vim does not synchronize anymore.
1941
1942
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001943PAPP *papp.vim* *ft-papp-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001944
1945The PApp syntax file handles .papp files and, to a lesser extend, .pxml
1946and .pxsl files which are all a mixture of perl/xml/html/other using xml
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001947as the top-level file format. By default everything inside phtml or pxml
1948sections is treated as a string with embedded preprocessor commands. If
Bram Moolenaar071d4272004-06-13 20:20:40 +00001949you set the variable: >
1950
1951 :let papp_include_html=1
1952
1953in your startup file it will try to syntax-hilight html code inside phtml
1954sections, but this is relatively slow and much too colourful to be able to
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001955edit sensibly. ;)
Bram Moolenaar071d4272004-06-13 20:20:40 +00001956
1957The newest version of the papp.vim syntax file can usually be found at
1958http://papp.plan9.de.
1959
1960
Bram Moolenaarda2303d2005-08-30 21:55:26 +00001961PASCAL *pascal.vim* *ft-pascal-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001962
1963Files matching "*.p" could be Progress or Pascal. If the automatic detection
1964doesn't work for you, or you don't edit Progress at all, use this in your
1965startup vimrc: >
1966
1967 :let filetype_p = "pascal"
1968
1969The Pascal syntax file has been extended to take into account some extensions
1970provided by Turbo Pascal, Free Pascal Compiler and GNU Pascal Compiler.
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00001971Delphi keywords are also supported. By default, Turbo Pascal 7.0 features are
Bram Moolenaar071d4272004-06-13 20:20:40 +00001972enabled. If you prefer to stick with the standard Pascal keywords, add the
1973following line to your startup file: >
1974
1975 :let pascal_traditional=1
1976
1977To switch on Delphi specific constructions (such as one-line comments,
1978keywords, etc): >
1979
1980 :let pascal_delphi=1
1981
1982
1983The option pascal_symbol_operator controls whether symbol operators such as +,
1984*, .., etc. are displayed using the Operator color or not. To colorize symbol
1985operators, add the following line to your startup file: >
1986
1987 :let pascal_symbol_operator=1
1988
1989Some functions are highlighted by default. To switch it off: >
1990
1991 :let pascal_no_functions=1
1992
Bram Moolenaar996343d2010-07-04 22:20:21 +02001993Furthermore, there are specific variables for some compilers. Besides
Bram Moolenaar071d4272004-06-13 20:20:40 +00001994pascal_delphi, there are pascal_gpc and pascal_fpc. Default extensions try to
1995match Turbo Pascal. >
1996
1997 :let pascal_gpc=1
1998
1999or >
2000
2001 :let pascal_fpc=1
2002
2003To ensure that strings are defined on a single line, you can define the
2004pascal_one_line_string variable. >
2005
2006 :let pascal_one_line_string=1
2007
2008If you dislike <Tab> chars, you can set the pascal_no_tabs variable. Tabs
2009will be highlighted as Error. >
2010
2011 :let pascal_no_tabs=1
2012
2013
2014

Bram Moolenaar071d4272004-06-13 20:20:40 +00002016
2017There are a number of possible options to the perl syntax highlighting.
2018

Bram Moolenaar071d4272004-06-13 20:20:40 +00002030
Bram Moolenaard4755bb2004-09-02 19:12:26 +00002031(In Vim 6.x it was the other way around: "perl_want_scope_in_variables"
2032enabled it.)
2033
2034If you do not want complex things like '@{${"foo"}}' to be parsed: >
2035
2036 :let perl_no_extended_vars = 1
2037
Bram Moolenaar3fdfa4a2004-10-07 21:02:47 +00002038(In Vim 6.x it was the other way around: "perl_extended_vars" enabled it.)
Bram Moolenaar071d4272004-06-13 20:20:40 +00002039
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002040The coloring strings can be changed. By default strings and qq friends will be
2041highlighted like the first line. If you set the variable
Bram Moolenaar071d4272004-06-13 20:20:40 +00002042perl_string_as_statement, it will be highlighted as in the second line.
2043
2044 "hello world!"; qq|hello world|;
2045 ^^^^^^^^^^^^^^NN^^^^^^^^^^^^^^^N (unlet perl_string_as_statement)
2046 S^^^^^^^^^^^^SNNSSS^^^^^^^^^^^SN (let perl_string_as_statement)
2047
2048(^ = perlString, S = perlStatement, N = None at all)
2049
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002050The syncing has 3 options. The first two switch off some triggering of
Bram Moolenaar071d4272004-06-13 20:20:40 +00002051synchronization and should only be needed in case it fails to work properly.
2052If while scrolling all of a sudden the whole screen changes color completely
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002053then you should try and switch off one of those. Let me know if you can figure
Bram Moolenaar071d4272004-06-13 20:20:40 +00002054out the line that causes the mistake.

Bram Moolenaar071d4272004-06-13 20:20:40 +00002185
2186There are several options when it comes to highlighting PostScript.
2187
2188First which version of the PostScript language to highlight. There are
2189currently three defined language versions, or levels. Level 1 is the original
2190and base version, and includes all extensions prior to the release of level 2.
2191Level 2 is the most common version around, and includes its own set of
2192extensions prior to the release of level 3. Level 3 is currently the highest
2193level supported. You select which level of the PostScript language you want
2194highlighted by defining the postscr_level variable as follows: >
2195
2196 :let postscr_level=2
2197
2198If this variable is not defined it defaults to 2 (level 2) since this is
2199the most prevalent version currently.
2200
2201Note, not all PS interpreters will support all language features for a
2202particular language level. In particular the %!PS-Adobe-3.0 at the start of
2203PS files does NOT mean the PostScript present is level 3 PostScript!
2204
2205If you are working with Display PostScript, you can include highlighting of
2206Display PS language features by defining the postscr_display variable as
2207follows: >
2208
2209 :let postscr_display=1
2210
2211If you are working with Ghostscript, you can include highlighting of
2212Ghostscript specific language features by defining the variable
2213postscr_ghostscript as follows: >
2214
2215 :let postscr_ghostscript=1
2216
2217PostScript is a large language, with many predefined elements. While it
2218useful to have all these elements highlighted, on slower machines this can
2219cause Vim to slow down. In an attempt to be machine friendly font names and
2220character encodings are not highlighted by default. Unless you are working
2221explicitly with either of these this should be ok. If you want them to be
2222highlighted you should set one or both of the following variables: >
2223
2224 :let postscr_fonts=1
2225 :let postscr_encodings=1
2226
2227There is a stylistic option to the highlighting of and, or, and not. In
2228PostScript the function of these operators depends on the types of their
2229operands - if the operands are booleans then they are the logical operators,
2230if they are integers then they are binary operators. As binary and logical
2231operators can be highlighted differently they have to be highlighted one way
2232or the other. By default they are treated as logical operators. They can be
2233highlighted as binary operators by defining the variable
2234postscr_andornot_binary as follows: >
2235
2236 :let postscr_andornot_binary=1
2237<
2238
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002239 *ptcap.vim* *ft-printcap-syntax*
2240PRINTCAP + TERMCAP *ft-ptcap-syntax* *ft-termcap-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002241
2242This syntax file applies to the printcap and termcap databases.
2243
2244In order for Vim to recognize printcap/termcap files that do not match
2245the patterns *printcap*, or *termcap*, you must put additional patterns
2246appropriate to your system in your |myfiletypefile| file. For these
2247patterns, you must set the variable "b:ptcap_type" to either "print" or
2248"term", and then the 'filetype' option to ptcap.
2249
2250For example, to make Vim identify all files in /etc/termcaps/ as termcap
2251files, add the following: >
2252
2253 :au BufNewFile,BufRead /etc/termcaps/* let b:ptcap_type = "term" |
2254 \ set filetype=ptcap
2255
2256If you notice highlighting errors while scrolling backwards, which
2257are fixed when redrawing with CTRL-L, try setting the "ptcap_minlines"
2258internal variable to a larger number: >
2259
2260 :let ptcap_minlines = 50
2261
2262(The default is 20 lines.)
2263
2264
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002265PROGRESS *progress.vim* *ft-progress-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002266
2267Files matching "*.w" could be Progress or cweb. If the automatic detection
2268doesn't work for you, or you don't edit cweb at all, use this in your
2269startup vimrc: >
2270 :let filetype_w = "progress"
2271The same happens for "*.i", which could be assembly, and "*.p", which could be
2272Pascal. Use this if you don't use assembly and Pascal: >
2273 :let filetype_i = "progress"
2274 :let filetype_p = "progress"
2275
2276
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002277PYTHON *python.vim* *ft-python-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002278
2279There are four options to control Python syntax highlighting.
2280
2281For highlighted numbers: >
2282 :let python_highlight_numbers = 1
2283
2284For highlighted builtin functions: >
2285 :let python_highlight_builtins = 1
2286
2287For highlighted standard exceptions: >
2288 :let python_highlight_exceptions = 1
2289
Bram Moolenaar4a748032010-09-30 21:47:56 +02002290For highlighted trailing whitespace and mix of spaces and tabs: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00002291 :let python_highlight_space_errors = 1
2292
2293If you want all possible Python highlighting (the same as setting the
2294preceding three options): >
2295 :let python_highlight_all = 1
2296
2297
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002298QUAKE *quake.vim* *ft-quake-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002299
2300The Quake syntax definition should work for most any FPS (First Person
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002301Shooter) based on one of the Quake engines. However, the command names vary
Bram Moolenaar071d4272004-06-13 20:20:40 +00002302a bit between the three games (Quake, Quake 2, and Quake 3 Arena) so the
2303syntax definition checks for the existence of three global variables to allow
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002304users to specify what commands are legal in their files. The three variables
Bram Moolenaar071d4272004-06-13 20:20:40 +00002305can be set for the following effects:
2306
2307set to highlight commands only available in Quake: >
2308 :let quake_is_quake1 = 1
2309
2310set to highlight commands only available in Quake 2: >
2311 :let quake_is_quake2 = 1
2312
2313set to highlight commands only available in Quake 3 Arena: >
2314 :let quake_is_quake3 = 1
2315
2316Any combination of these three variables is legal, but might highlight more
2317commands than are actually available to you by the game.
2318
2319
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002320READLINE *readline.vim* *ft-readline-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002321
2322The readline library is primarily used by the BASH shell, which adds quite a
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002323few commands and options to the ones already available. To highlight these
Bram Moolenaar071d4272004-06-13 20:20:40 +00002324items as well you can add the following to your |vimrc| or just type it in the
2325command line before loading a file with the readline syntax: >
2326 let readline_has_bash = 1
2327
2328This will add highlighting for the commands that BASH (version 2.05a and
2329later, and part earlier) adds.
2330
2331
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002332REXX *rexx.vim* *ft-rexx-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002333
2334If you notice highlighting errors while scrolling backwards, which are fixed
2335when redrawing with CTRL-L, try setting the "rexx_minlines" internal variable
2336to a larger number: >
2337 :let rexx_minlines = 50
2338This will make the syntax synchronization start 50 lines before the first
2339displayed line. The default value is 10. The disadvantage of using a larger
2340number is that redrawing can become slow.
2341
2342
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002343RUBY *ruby.vim* *ft-ruby-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002344
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002345There are a number of options to the Ruby syntax highlighting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002346
2347By default, the "end" keyword is colorized according to the opening statement
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002348of the block it closes. While useful, this feature can be expensive; if you
Bram Moolenaar071d4272004-06-13 20:20:40 +00002349experience slow redrawing (or you are on a terminal with poor color support)
2350you may want to turn it off by defining the "ruby_no_expensive" variable: >
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002351
Bram Moolenaar071d4272004-06-13 20:20:40 +00002352 :let ruby_no_expensive = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002353<
Bram Moolenaar071d4272004-06-13 20:20:40 +00002354In this case the same color will be used for all control keywords.
2355
2356If you do want this feature enabled, but notice highlighting errors while
2357scrolling backwards, which are fixed when redrawing with CTRL-L, try setting
2358the "ruby_minlines" variable to a value larger than 50: >
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002359
Bram Moolenaar071d4272004-06-13 20:20:40 +00002360 :let ruby_minlines = 100
Bram Moolenaar25394022007-05-10 19:06:20 +00002361<
Bram Moolenaar071d4272004-06-13 20:20:40 +00002362Ideally, this value should be a number of lines large enough to embrace your
2363largest class or module.
2364
Bram Moolenaar25394022007-05-10 19:06:20 +00002365Highlighting of special identifiers can be disabled by removing the
2366rubyIdentifier highlighting: >
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002367
Bram Moolenaar25394022007-05-10 19:06:20 +00002368 :hi link rubyIdentifier NONE
2369<
Bram Moolenaar071d4272004-06-13 20:20:40 +00002370This will prevent highlighting of special identifiers like "ConstantName",
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002371"$global_var", "@@class_var", "@instance_var", "| block_param |", and
2372":symbol".
Bram Moolenaar071d4272004-06-13 20:20:40 +00002373
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002374Significant methods of Kernel, Module and Object are highlighted by default.
2375This can be disabled by defining "ruby_no_special_methods": >
Bram Moolenaar071d4272004-06-13 20:20:40 +00002376
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002377 :let ruby_no_special_methods = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002378<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002379This will prevent highlighting of important methods such as "require", "attr",
2380"private", "raise" and "proc".
2381
Bram Moolenaar25394022007-05-10 19:06:20 +00002382Ruby operators can be highlighted. This is enabled by defining
2383"ruby_operators": >
2384
2385 :let ruby_operators = 1
2386<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002387Whitespace errors can be highlighted by defining "ruby_space_errors": >
2388
2389 :let ruby_space_errors = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002390<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002391This will highlight trailing whitespace and tabs preceded by a space character
2392as errors. This can be refined by defining "ruby_no_trail_space_error" and
2393"ruby_no_tab_space_error" which will ignore trailing whitespace and tabs after
2394spaces respectively.
2395
2396Folding can be enabled by defining "ruby_fold": >
2397
2398 :let ruby_fold = 1
Bram Moolenaar25394022007-05-10 19:06:20 +00002399<
Bram Moolenaar943d2b52005-12-02 00:50:49 +00002400This will set the 'foldmethod' option to "syntax" and allow folding of
2401classes, modules, methods, code blocks, heredocs and comments.
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00002402
Bram Moolenaar25394022007-05-10 19:06:20 +00002403Folding of multiline comments can be disabled by defining
2404"ruby_no_comment_fold": >
2405
2406 :let ruby_no_comment_fold = 1
2407<

Bram Moolenaarda2303d2005-08-30 21:55:26 +00002409SCHEME *scheme.vim* *ft-scheme-syntax*
Bram Moolenaar21cf8232004-07-16 20:18:37 +00002410
2411By default only R5RS keywords are highlighted and properly indented.
2412
2413MzScheme-specific stuff will be used if b:is_mzscheme or g:is_mzscheme
2414variables are defined.
Bram Moolenaarc9b4b052006-04-30 18:54:39 +00002415
Bram Moolenaar293ee4d2004-12-09 21:34:53 +00002416Also scheme.vim supports keywords of the Chicken Scheme->C compiler. Define
2417b:is_chicken or g:is_chicken, if you need them.
Bram Moolenaar21cf8232004-07-16 20:18:37 +00002418

Bram Moolenaarda2303d2005-08-30 21:55:26 +00002420SDL *sdl.vim* *ft-sdl-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002421
2422The SDL highlighting probably misses a few keywords, but SDL has so many
2423of them it's almost impossibly to cope.
2424
2425The new standard, SDL-2000, specifies that all identifiers are
2426case-sensitive (which was not so before), and that all keywords can be
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002427used either completely lowercase or completely uppercase. To have the
Bram Moolenaar071d4272004-06-13 20:20:40 +00002428highlighting reflect this, you can set the following variable: >
2429 :let sdl_2000=1
2430
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002431This also sets many new keywords. If you want to disable the old
Bram Moolenaar071d4272004-06-13 20:20:40 +00002432keywords, which is probably a good idea, use: >
2433 :let SDL_no_96=1
2434
2435
2436The indentation is probably also incomplete, but right now I am very
2437satisfied with it for my own projects.
2438
2439
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002440SED *sed.vim* *ft-sed-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002441
2442To make tabs stand out from regular blanks (accomplished by using Todo
2443highlighting on the tabs), define "highlight_sedtabs" by putting >
2444
2445 :let highlight_sedtabs = 1
2446
2447in the vimrc file. (This special highlighting only applies for tabs
2448inside search patterns, replacement texts, addresses or text included
2449by an Append/Change/Insert command.) If you enable this option, it is
2450also a good idea to set the tab width to one character; by doing that,
2451you can easily count the number of tabs in a string.
2452
2453Bugs:
2454
2455 The transform command (y) is treated exactly like the substitute
2456 command. This means that, as far as this syntax file is concerned,
2457 transform accepts the same flags as substitute, which is wrong.
2458 (Transform accepts no flags.) I tolerate this bug because the
2459 involved commands need very complex treatment (95 patterns, one for
2460 each plausible pattern delimiter).
2461
2462
Bram Moolenaarda2303d2005-08-30 21:55:26 +00002463SGML *sgml.vim* *ft-sgml-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002464
2465The coloring scheme for tags in the SGML file works as follows.
2466
2467The <> of opening tags are colored differently than the </> of a closing tag.
2468This is on purpose! For opening tags the 'Function' color is used, while for
2469closing tags the 'Type' color is used (See syntax.vim to check how those are
2470defined for you)
2471
2472Known tag names are colored the same way as statements in C. Unknown tag
2473names are not colored which makes it easy to spot errors.
2474
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002475Note that the same is true for argument (or attribute) names. Known attribute
Bram Moolenaar071d4272004-06-13 20:20:40 +00002476names are colored differently than unknown ones.
2477
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002478Some SGML tags are used to change the rendering of text. The following tags
Bram Moolenaar071d4272004-06-13 20:20:40 +00002479are recognized by the sgml.vim syntax coloring file and change the way normal
2480text is shown: <varname> <emphasis> <command> <function> <literal>
2481<replaceable> <ulink> and <link>.
2482
2483If you want to change how such text is rendered, you must redefine the
2484following syntax groups:
2485
2486 - sgmlBold
2487 - sgmlBoldItalic
2488 - sgmlUnderline
2489 - sgmlItalic
2490 - sgmlLink for links
2491
2492To make this redefinition work you must redefine them all and define the
2493following variable in your vimrc (this is due to the order in which the files
2494are read during initialization) >
2495 let sgml_my_rendering=1
2496
2497You can also disable this rendering by adding the following line to your
2498vimrc file: >
2499 let sgml_no_rendering=1

Bram Moolenaar8c8de832008-06-24 22:58:06 +00002506This covers the "normal" Unix (Bourne) sh, bash and the Korn shell.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002507
2508Vim attempts to determine which shell type is in use by specifying that
2509various filenames are of specific types: >
2510
2511 ksh : .kshrc* *.ksh
2512 bash: .bashrc* bashrc bash.bashrc .bash_profile* *.bash
2513<
2514If none of these cases pertain, then the first line of the file is examined
2515(ex. /bin/sh /bin/ksh /bin/bash). If the first line specifies a shelltype,
2516then that shelltype is used. However some files (ex. .profile) are known to
2517be shell files but the type is not apparent. Furthermore, on many systems
Bram Moolenaar7fc904b2006-04-13 20:37:35 +00002518sh is symbolically linked to "bash" (Linux, Windows+cygwin) or "ksh" (Posix).

Bram Moolenaar8c8de832008-06-24 22:58:06 +00002538The syntax/sh.vim file provides several levels of syntax-based folding: >
2539
2540 let g:sh_fold_enabled= 0 (default, no syntax folding)
2541 let g:sh_fold_enabled= 1 (enable function folding)
2542 let g:sh_fold_enabled= 2 (enable heredoc folding)
2543 let g:sh_fold_enabled= 4 (enable if/do/for folding)
Bram Moolenaar071d4272004-06-13 20:20:40 +00002544>
2545then various syntax items (HereDocuments and function bodies) become
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002546syntax-foldable (see |:syn-fold|). You also may add these together
2547to get multiple types of folding: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00002548
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002549 let g:sh_fold_enabled= 3 (enables function and heredoc folding)
2550
2551If you notice highlighting errors while scrolling backwards which are fixed
2552when one redraws with CTRL-L, try setting the "sh_minlines" internal variable
Bram Moolenaar071d4272004-06-13 20:20:40 +00002553to a larger number. Example: >
2554
2555 let sh_minlines = 500
2556
2557This will make syntax synchronization start 500 lines before the first
2558displayed line. The default value is 200. The disadvantage of using a larger
2559number is that redrawing can become slow.
2560
2561If you don't have much to synchronize on, displaying can be very slow. To
2562reduce this, the "sh_maxlines" internal variable can be set. Example: >
2563
2564 let sh_maxlines = 100
2565<
2566The default is to use the twice sh_minlines. Set it to a smaller number to
2567speed up displaying. The disadvantage is that highlight errors may appear.

Bram Moolenaar071d4272004-06-13 20:20:40 +00002571
2572The Speedup syntax file has some options:
2573
2574- strict_subsections : If this variable is defined, only keywords for
2575 sections and subsections will be highlighted as statements but not
2576 other keywords (like WITHIN in the OPERATION section).
2577
2578- highlight_types : Definition of this variable causes stream types
2579 like temperature or pressure to be highlighted as Type, not as a
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002580 plain Identifier. Included are the types that are usually found in
Bram Moolenaar071d4272004-06-13 20:20:40 +00002581 the DECLARE section; if you defined own types, you have to include
2582 them in the syntax file.
2583
2584- oneline_comments : this value ranges from 1 to 3 and determines the
2585 highlighting of # style comments.
2586
2587 oneline_comments = 1 : allow normal Speedup code after an even
2588 number of #s.
2589
2590 oneline_comments = 2 : show code starting with the second # as
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002591 error. This is the default setting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002592
2593 oneline_comments = 3 : show the whole line as error if it contains
2594 more than one #.
2595
2596Since especially OPERATION sections tend to become very large due to
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002597PRESETting variables, syncing may be critical. If your computer is
Bram Moolenaar071d4272004-06-13 20:20:40 +00002598fast enough, you can increase minlines and/or maxlines near the end of
2599the syntax file.

Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01002635This will make the syntax synchronization start 1000 lines before the first
2636displayed line. If you set "tcsh_minlines" to "fromstart", then
2637synchronization is done from the start of the file. The default value for
2638tcsh_minlines is 100. The disadvantage of using a larger number is that

Bram Moolenaar488c6512005-08-11 20:09:58 +00002673The <syntax/tex.vim> highlighting supports TeX, LaTeX, and some AmsTeX. The
2674highlighting supports three primary zones/regions: normal, texZone, and
2675texMathZone. Although considerable effort has been made to have these zones
2676terminate properly, zones delineated by $..$ and $$..$$ cannot be synchronized
2677as there's no difference between start and end patterns. Consequently, a

2706The <tex.vim> supports lexical error checking of various sorts. Thus,
2707although the error checking is ofttimes very useful, it can indicate
2708errors where none actually are. If this proves to be a problem for you,

Bram Moolenaar488c6512005-08-11 20:09:58 +00002718 call TexNewMathZone(sfx,mathzone,starform)
2719You'll want to provide the new math group with a unique suffix
2720(currently, A-L and V-Z are taken by <syntax/tex.vim> itself).
2721As an example, consider how eqnarray is set up by <syntax/tex.vim>: >
2722 call TexNewMathZone("D","eqnarray",1)
2723You'll need to change "mathzone" to the name of your new math group,
2724and then to the call to it in .vim/after/syntax/tex.vim.
2725The "starform" variable, if true, implies that your new math group
2726has a starred form (ie. eqnarray*).

Bram Moolenaar477db062010-07-28 18:17:41 +02002745If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a

2747including various accented characters, Greek characters in MathZones, and
2748superscripts and subscripts in MathZones. Not all characters can be made into
2749superscripts or subscripts; the constraint is due to what utf-8 supports.
2750In fact, only a few characters are supported as subscripts.
2751
2752One way to use this is to have vertically split windows (see |CTRL-W_v|); one
2753with |'conceallevel'| at 0 and the other at 2; and both using |'scrollbind'|.

2827difficult language to highlight correctly. A way to suppress error
Bram Moolenaar8c8de832008-06-24 22:58:06 +00002828highlighting is to put the following line in your |vimrc|: >

Bram Moolenaar071d4272004-06-13 20:20:40 +00002835
2836The syntax of XF86Config file differs in XFree86 v3.x and v4.x. Both
2837variants are supported. Automatic detection is used, but is far from perfect.
2838You may need to specify the version manually. Set the variable
2839xf86conf_xfree86_version to 3 or 4 according to your XFree86 version in
2840your .vimrc. Example: >
2841 :let xf86conf_xfree86_version=3
2842When using a mix of versions, set the b:xf86conf_xfree86_version variable.
2843
2844Note that spaces and underscores in option names are not supported. Use
2845"SyncOnGreen" instead of "__s yn con gr_e_e_n" if you want the option name
2846highlighted.

Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002851Xml namespaces are highlighted by default. This can be inhibited by
Bram Moolenaar071d4272004-06-13 20:20:40 +00002852setting a global variable: >
2853

2855<
2856 *xml-folding*
2857The xml syntax file provides syntax |folding| (see |:syn-fold|) between
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00002858start and end tags. This can be turned on by >

2860 :let g:xml_syntax_folding = 1

2864especially for large files.

Bram Moolenaarda2303d2005-08-30 21:55:26 +00002867X Pixmaps (XPM) *xpm.vim* *ft-xpm-syntax*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002868
2869xpm.vim creates its syntax items dynamically based upon the contents of the
2870XPM file. Thus if you make changes e.g. in the color specification strings,
2871you have to source it again e.g. with ":set syn=xpm".
2872
2873To copy a pixel with one of the colors, yank a "pixel" with "yl" and insert it
2874somewhere else with "P".
2875
2876Do you want to draw with the mouse? Try the following: >
2877 :function! GetPixel()
Bram Moolenaar61660ea2006-04-07 21:40:07 +00002878 : let c = getline(".")[col(".") - 1]
Bram Moolenaar071d4272004-06-13 20:20:40 +00002879 : echo c
2880 : exe "noremap <LeftMouse> <LeftMouse>r".c
2881 : exe "noremap <LeftDrag> <LeftMouse>r".c
2882 :endfunction
2883 :noremap <RightMouse> <LeftMouse>:call GetPixel()<CR>
2884 :set guicursor=n:hor20 " to see the color beneath the cursor
2885This turns the right button into a pipette and the left button into a pen.
2886It will work with XPM files that have one character per pixel only and you
2887must not click outside of the pixel strings, but feel free to improve it.
2888
2889It will look much better with a font in a quadratic cell size, e.g. for X: >
2890 :set guifont=-*-clean-medium-r-*-*-8-*-*-*-*-80-*
2891
2892==============================================================================
28935. Defining a syntax *:syn-define* *E410*
2894
2895Vim understands three types of syntax items:
2896
Bram Moolenaarce0842a2005-07-18 21:58:11 +000028971. Keyword
Bram Moolenaar071d4272004-06-13 20:20:40 +00002898 It can only contain keyword characters, according to the 'iskeyword'
2899 option. It cannot contain other syntax items. It will only match with a
2900 complete word (there are no keyword characters before or after the match).
2901 The keyword "if" would match in "if(a=b)", but not in "ifdef x", because
2902 "(" is not a keyword character and "d" is.
2903
Bram Moolenaarce0842a2005-07-18 21:58:11 +000029042. Match
Bram Moolenaar071d4272004-06-13 20:20:40 +00002905 This is a match with a single regexp pattern.
2906
Bram Moolenaarce0842a2005-07-18 21:58:11 +000029073. Region
Bram Moolenaar071d4272004-06-13 20:20:40 +00002908 This starts at a match of the "start" regexp pattern and ends with a match
2909 with the "end" regexp pattern. Any other text can appear in between. A
2910 "skip" regexp pattern can be used to avoid matching the "end" pattern.
2911
2912Several syntax ITEMs can be put into one syntax GROUP. For a syntax group
2913you can give highlighting attributes. For example, you could have an item
2914to define a "/* .. */" comment and another one that defines a "// .." comment,
2915and put them both in the "Comment" group. You can then specify that a
2916"Comment" will be in bold font and have a blue color. You are free to make
2917one highlight group for one syntax item, or put all items into one group.
2918This depends on how you want to specify your highlighting attributes. Putting
2919each item in its own group results in having to specify the highlighting
2920for a lot of groups.
2921
2922Note that a syntax group and a highlight group are similar. For a highlight
2923group you will have given highlight attributes. These attributes will be used
2924for the syntax group with the same name.
2925
2926In case more than one item matches at the same position, the one that was
2927defined LAST wins. Thus you can override previously defined syntax items by
2928using an item that matches the same text. But a keyword always goes before a
2929match or region. And a keyword with matching case always goes before a
2930keyword with ignoring case.
2931
2932
2933PRIORITY *:syn-priority*
2934
2935When several syntax items may match, these rules are used:
2936
29371. When multiple Match or Region items start in the same position, the item
2938 defined last has priority.
29392. A Keyword has priority over Match and Region items.
29403. An item that starts in an earlier position has priority over items that
2941 start in later positions.
2942
2943
2944DEFINING CASE *:syn-case* *E390*
2945
Bram Moolenaarce0842a2005-07-18 21:58:11 +00002946:sy[ntax] case [match | ignore]
Bram Moolenaar071d4272004-06-13 20:20:40 +00002947 This defines if the following ":syntax" commands will work with
2948 matching case, when using "match", or with ignoring case, when using
2949 "ignore". Note that any items before this are not affected, and all
2950 items until the next ":syntax case" command are affected.
2951
2952
Bram Moolenaarce0842a2005-07-18 21:58:11 +00002953SPELL CHECKING *:syn-spell*
2954
2955:sy[ntax] spell [toplevel | notoplevel | default]
2956 This defines where spell checking is to be done for text that is not
2957 in a syntax item:
2958
2959 toplevel: Text is spell checked.
2960 notoplevel: Text is not spell checked.
2961 default: When there is a @Spell cluster no spell checking.
2962
2963 For text in syntax items use the @Spell and @NoSpell clusters
2964 |spell-syntax|. When there is no @Spell and no @NoSpell cluster then
2965 spell checking is done for "default" and "toplevel".
2966
2967 To activate spell checking the 'spell' option must be set.
2968
2969
Bram Moolenaar071d4272004-06-13 20:20:40 +00002970DEFINING KEYWORDS *:syn-keyword*
2971
2972:sy[ntax] keyword {group-name} [{options}] {keyword} .. [{options}]
2973
2974 This defines a number of keywords.
2975
2976 {group-name} Is a syntax group name such as "Comment".
2977 [{options}] See |:syn-arguments| below.
2978 {keyword} .. Is a list of keywords which are part of this group.
2979
2980 Example: >
2981 :syntax keyword Type int long char
2982<
2983 The {options} can be given anywhere in the line. They will apply to
2984 all keywords given, also for options that come after a keyword.
2985 These examples do exactly the same: >
2986 :syntax keyword Type contained int long char
2987 :syntax keyword Type int long contained char
2988 :syntax keyword Type int long char contained
Bram Moolenaarfc1421e2006-04-20 22:17:20 +00002989< *E789*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002990 When you have a keyword with an optional tail, like Ex commands in
2991 Vim, you can put the optional characters inside [], to define all the
2992 variations at once: >
2993 :syntax keyword vimCommand ab[breviate] n[ext]
2994<
2995 Don't forget that a keyword can only be recognized if all the
2996 characters are included in the 'iskeyword' option. If one character
2997 isn't, the keyword will never be recognized.
2998 Multi-byte characters can also be used. These do not have to be in
2999 'iskeyword'.
3000
3001 A keyword always has higher priority than a match or region, the
3002 keyword is used if more than one item matches. Keywords do not nest
3003 and a keyword can't contain anything else.
3004
3005 Note that when you have a keyword that is the same as an option (even
3006 one that isn't allowed here), you can not use it. Use a match
3007 instead.
3008
3009 The maximum length of a keyword is 80 characters.
3010
3011 The same keyword can be defined multiple times, when its containment
3012 differs. For example, you can define the keyword once not contained
3013 and use one highlight group, and once contained, and use a different
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00003014 highlight group. Example: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00003015 :syn keyword vimCommand tag
3016 :syn keyword vimSetting contained tag
3017< When finding "tag" outside of any syntax item, the "vimCommand"
3018 highlight group is used. When finding "tag" in a syntax item that
3019 contains "vimSetting", the "vimSetting" group is used.
3020
3021
3022DEFINING MATCHES *:syn-match*
3023
3024:sy[ntax] match {group-name} [{options}] [excludenl] {pattern} [{options}]
3025
3026 This defines one match.
3027
3028 {group-name} A syntax group name such as "Comment".
3029 [{options}] See |:syn-arguments| below.
3030 [excludenl] Don't make a pattern with the end-of-line "$"
3031 extend a containing match or region. Must be
3032 given before the pattern. |:syn-excludenl|
3033 {pattern} The search pattern that defines the match.
3034 See |:syn-pattern| below.
3035 Note that the pattern may match more than one
3036 line, which makes the match depend on where
3037 Vim starts searching for the pattern. You
3038 need to make sure syncing takes care of this.
3039
3040 Example (match a character constant): >
3041 :syntax match Character /'.'/hs=s+1,he=e-1
3042<
3043
3044DEFINING REGIONS *:syn-region* *:syn-start* *:syn-skip* *:syn-end*
3045 *E398* *E399*
3046:sy[ntax] region {group-name} [{options}]
3047 [matchgroup={group-name}]
3048 [keepend]
3049 [extend]
3050 [excludenl]
3051 start={start_pattern} ..
3052 [skip={skip_pattern}]
3053 end={end_pattern} ..
3054 [{options}]
3055
3056 This defines one region. It may span several lines.
3057
3058 {group-name} A syntax group name such as "Comment".
3059 [{options}] See |:syn-arguments| below.
3060 [matchgroup={group-name}] The syntax group to use for the following
3061 start or end pattern matches only. Not used
3062 for the text in between the matched start and
3063 end patterns. Use NONE to reset to not using
3064 a different group for the start or end match.
3065 See |:syn-matchgroup|.
3066 keepend Don't allow contained matches to go past a
3067 match with the end pattern. See
3068 |:syn-keepend|.
3069 extend Override a "keepend" for an item this region
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00003070 is contained in. See |:syn-extend|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003071 excludenl Don't make a pattern with the end-of-line "$"
3072 extend a containing match or item. Only
3073 useful for end patterns. Must be given before
3074 the patterns it applies to. |:syn-excludenl|
3075 start={start_pattern} The search pattern that defines the start of
3076 the region. See |:syn-pattern| below.
3077 skip={skip_pattern} The search pattern that defines text inside
3078 the region where not to look for the end
3079 pattern. See |:syn-pattern| below.
3080 end={end_pattern} The search pattern that defines the end of
3081 the region. See |:syn-pattern| below.
3082
3083 Example: >
3084 :syntax region String start=+"+ skip=+\\"+ end=+"+
3085<
3086 The start/skip/end patterns and the options can be given in any order.
3087 There can be zero or one skip pattern. There must be one or more
3088 start and end patterns. This means that you can omit the skip
3089 pattern, but you must give at least one start and one end pattern. It
3090 is allowed to have white space before and after the equal sign
3091 (although it mostly looks better without white space).
3092
3093 When more than one start pattern is given, a match with one of these
3094 is sufficient. This means there is an OR relation between the start
3095 patterns. The last one that matches is used. The same is true for
3096 the end patterns.
3097
3098 The search for the end pattern starts right after the start pattern.
3099 Offsets are not used for this. This implies that the match for the
3100 end pattern will never overlap with the start pattern.
3101
3102 The skip and end pattern can match across line breaks, but since the
3103 search for the pattern can start in any line it often does not do what
3104 you want. The skip pattern doesn't avoid a match of an end pattern in
3105 the next line. Use single-line patterns to avoid trouble.
3106
3107 Note: The decision to start a region is only based on a matching start
3108 pattern. There is no check for a matching end pattern. This does NOT
3109 work: >
3110 :syn region First start="(" end=":"
3111 :syn region Second start="(" end=";"
3112< The Second always matches before the First (last defined pattern has
3113 higher priority). The Second region then continues until the next
3114 ';', no matter if there is a ':' before it. Using a match does work: >
3115 :syn match First "(\_.\{-}:"
3116 :syn match Second "(\_.\{-};"
3117< This pattern matches any character or line break with "\_." and
3118 repeats that with "\{-}" (repeat as few as possible).
3119
3120 *:syn-keepend*
3121 By default, a contained match can obscure a match for the end pattern.
3122 This is useful for nesting. For example, a region that starts with
3123 "{" and ends with "}", can contain another region. An encountered "}"
3124 will then end the contained region, but not the outer region:
3125 { starts outer "{}" region
3126 { starts contained "{}" region
3127 } ends contained "{}" region
3128 } ends outer "{} region
3129 If you don't want this, the "keepend" argument will make the matching
3130 of an end pattern of the outer region also end any contained item.
3131 This makes it impossible to nest the same region, but allows for
3132 contained items to highlight parts of the end pattern, without causing
3133 that to skip the match with the end pattern. Example: >
3134 :syn match vimComment +"[^"]\+$+
3135 :syn region vimCommand start="set" end="$" contains=vimComment keepend
3136< The "keepend" makes the vimCommand always end at the end of the line,
3137 even though the contained vimComment includes a match with the <EOL>.
3138
3139 When "keepend" is not used, a match with an end pattern is retried
3140 after each contained match. When "keepend" is included, the first
3141 encountered match with an end pattern is used, truncating any
3142 contained matches.
3143 *:syn-extend*
3144 The "keepend" behavior can be changed by using the "extend" argument.
3145 When an item with "extend" is contained in an item that uses
3146 "keepend", the "keepend" is ignored and the containing region will be
3147 extended.
3148 This can be used to have some contained items extend a region while
3149 others don't. Example: >
3150
3151 :syn region htmlRef start=+<a>+ end=+</a>+ keepend contains=htmlItem,htmlScript
3152 :syn match htmlItem +<[^>]*>+ contained
3153 :syn region htmlScript start=+<script+ end=+</script[^>]*>+ contained extend
3154
3155< Here the htmlItem item does not make the htmlRef item continue
3156 further, it is only used to highlight the <> items. The htmlScript
3157 item does extend the htmlRef item.
3158
3159 Another example: >
3160 :syn region xmlFold start="<a>" end="</a>" fold transparent keepend extend
3161< This defines a region with "keepend", so that its end cannot be
3162 changed by contained items, like when the "</a>" is matched to
3163 highlight it differently. But when the xmlFold region is nested (it
3164 includes itself), the "extend" applies, so that the "</a>" of a nested
3165 region only ends that region, and not the one it is contained in.
3166
3167 *:syn-excludenl*
3168 When a pattern for a match or end pattern of a region includes a '$'
3169 to match the end-of-line, it will make a region item that it is
3170 contained in continue on the next line. For example, a match with
3171 "\\$" (backslash at the end of the line) can make a region continue
3172 that would normally stop at the end of the line. This is the default
3173 behavior. If this is not wanted, there are two ways to avoid it:
3174 1. Use "keepend" for the containing item. This will keep all
3175 contained matches from extending the match or region. It can be
3176 used when all contained items must not extend the containing item.
3177 2. Use "excludenl" in the contained item. This will keep that match
3178 from extending the containing match or region. It can be used if
3179 only some contained items must not extend the containing item.
3180 "excludenl" must be given before the pattern it applies to.
3181
3182 *:syn-matchgroup*
3183 "matchgroup" can be used to highlight the start and/or end pattern
3184 differently than the body of the region. Example: >
3185 :syntax region String matchgroup=Quote start=+"+ skip=+\\"+ end=+"+
3186< This will highlight the quotes with the "Quote" group, and the text in
3187 between with the "String" group.
3188 The "matchgroup" is used for all start and end patterns that follow,
3189 until the next "matchgroup". Use "matchgroup=NONE" to go back to not
3190 using a matchgroup.
3191
3192 In a start or end pattern that is highlighted with "matchgroup" the
3193 contained items of the region are not used. This can be used to avoid
3194 that a contained item matches in the start or end pattern match. When
3195 using "transparent", this does not apply to a start or end pattern
3196 match that is highlighted with "matchgroup".
3197
3198 Here is an example, which highlights three levels of parentheses in
3199 different colors: >
3200 :sy region par1 matchgroup=par1 start=/(/ end=/)/ contains=par2
3201 :sy region par2 matchgroup=par2 start=/(/ end=/)/ contains=par3 contained
3202 :sy region par3 matchgroup=par3 start=/(/ end=/)/ contains=par1 contained
3203 :hi par1 ctermfg=red guifg=red
3204 :hi par2 ctermfg=blue guifg=blue
3205 :hi par3 ctermfg=darkgreen guifg=darkgreen
3206

Bram Moolenaar860cae12010-06-05 23:22:07 +02003233conceal *conceal* *:syn-conceal*
3234
3235When the "conceal" argument is given, the item is marked as concealable.
Bram Moolenaar370df582010-06-22 05:16:38 +02003236Whether or not it is actually concealed depends on the value of the
Bram Moolenaarf5963f72010-07-23 22:10:27 +02003237'conceallevel' option. The 'concealcursor' option is used to decide whether
3238concealable items in the current line are displayed unconcealed to be able to
3239edit the line.
Bram Moolenaar860cae12010-06-05 23:22:07 +02003240
3241concealends *:syn-concealends*
3242
3243When the "concealends" argument is given, the start and end matches of
3244the region, but not the contents of the region, are marked as concealable.
3245Whether or not they are actually concealed depends on the setting on the
3246'conceallevel' option. The ends of a region can only be concealed separately
3247in this way when they have their own highlighting via "matchgroup"
3248
3249cchar *:syn-cchar*
3250
3251The "cchar" argument defines the character shown in place of the item
3252when it is concealed (setting "cchar" only makes sense when the conceal
3253argument is given.) If "cchar" is not set then the default conceal
3254character defined in the 'listchars' option is used. Example: >
3255 :syntax match Entity "&amp;" conceal cchar=&
Bram Moolenaar9028b102010-07-11 16:58:51 +02003256See |hl-Conceal| for highlighting.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003257
3258contained *:syn-contained*
3259
3260When the "contained" argument is given, this item will not be recognized at
3261the top level, but only when it is mentioned in the "contains" field of
3262another match. Example: >
3263 :syntax keyword Todo TODO contained
3264 :syntax match Comment "//.*" contains=Todo
3265
3266
3267display *:syn-display*
3268
3269If the "display" argument is given, this item will be skipped when the
3270detected highlighting will not be displayed. This will speed up highlighting,
3271by skipping this item when only finding the syntax state for the text that is
3272to be displayed.
3273
3274Generally, you can use "display" for match and region items that meet these
3275conditions:
3276- The item does not continue past the end of a line. Example for C: A region
3277 for a "/*" comment can't contain "display", because it continues on the next
3278 line.
3279- The item does not contain items that continue past the end of the line or
3280 make it continue on the next line.
3281- The item does not change the size of any item it is contained in. Example
3282 for C: A match with "\\$" in a preprocessor match can't have "display",
3283 because it may make that preprocessor match shorter.
3284- The item does not allow other items to match that didn't match otherwise,
3285 and that item may extend the match too far. Example for C: A match for a
3286 "//" comment can't use "display", because a "/*" inside that comment would
3287 match then and start a comment which extends past the end of the line.
3288
3289Examples, for the C language, where "display" can be used:
3290- match with a number
3291- match with a label
3292
3293
3294transparent *:syn-transparent*
3295
3296If the "transparent" argument is given, this item will not be highlighted
3297itself, but will take the highlighting of the item it is contained in. This
3298is useful for syntax items that don't need any highlighting but are used
3299only to skip over a part of the text.
3300
3301The "contains=" argument is also inherited from the item it is contained in,
3302unless a "contains" argument is given for the transparent item itself. To
3303avoid that unwanted items are contained, use "contains=NONE". Example, which
3304highlights words in strings, but makes an exception for "vim": >
3305 :syn match myString /'[^']*'/ contains=myWord,myVim
3306 :syn match myWord /\<[a-z]*\>/ contained
3307 :syn match myVim /\<vim\>/ transparent contained contains=NONE
3308 :hi link myString String
3309 :hi link myWord Comment
3310Since the "myVim" match comes after "myWord" it is the preferred match (last
3311match in the same position overrules an earlier one). The "transparent"
3312argument makes the "myVim" match use the same highlighting as "myString". But
3313it does not contain anything. If the "contains=NONE" argument would be left
3314out, then "myVim" would use the contains argument from myString and allow
3315"myWord" to be contained, which will be highlighted as a Constant. This
3316happens because a contained match doesn't match inside itself in the same
3317position, thus the "myVim" match doesn't overrule the "myWord" match here.
3318
3319When you look at the colored text, it is like looking at layers of contained
3320items. The contained item is on top of the item it is contained in, thus you
3321see the contained item. When a contained item is transparent, you can look
3322through, thus you see the item it is contained in. In a picture:
3323
3324 look from here
3325
3326 | | | | | |
3327 V V V V V V
3328
3329 xxxx yyy more contained items
3330 .................... contained item (transparent)
3331 ============================= first item
3332
3333The 'x', 'y' and '=' represent a highlighted syntax item. The '.' represent a
3334transparent group.
3335
3336What you see is:
3337
3338 =======xxxx=======yyy========
3339
3340Thus you look through the transparent "....".
3341
3342
3343oneline *:syn-oneline*
3344
3345The "oneline" argument indicates that the region does not cross a line
3346boundary. It must match completely in the current line. However, when the
3347region has a contained item that does cross a line boundary, it continues on
3348the next line anyway. A contained item can be used to recognize a line
3349continuation pattern. But the "end" pattern must still match in the first
3350line, otherwise the region doesn't even start.
3351
3352When the start pattern includes a "\n" to match an end-of-line, the end
3353pattern must be found in the same line as where the start pattern ends. The
3354end pattern may also include an end-of-line. Thus the "oneline" argument
3355means that the end of the start pattern and the start of the end pattern must
3356be within one line. This can't be changed by a skip pattern that matches a
3357line break.
3358
3359
3360fold *:syn-fold*
3361
Bram Moolenaar8c8de832008-06-24 22:58:06 +00003362The "fold" argument makes the fold level increase by one for this item.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003363Example: >
3364 :syn region myFold start="{" end="}" transparent fold
3365 :syn sync fromstart
3366 :set foldmethod=syntax
3367This will make each {} block form one fold.
3368
3369The fold will start on the line where the item starts, and end where the item
3370ends. If the start and end are within the same line, there is no fold.
3371The 'foldnestmax' option limits the nesting of syntax folds.
3372{not available when Vim was compiled without |+folding| feature}
3373
3374
3375 *:syn-contains* *E405* *E406* *E407* *E408* *E409*
3376contains={groupname},..
3377
3378The "contains" argument is followed by a list of syntax group names. These
3379groups will be allowed to begin inside the item (they may extend past the
3380containing group's end). This allows for recursive nesting of matches and
3381regions. If there is no "contains" argument, no groups will be contained in
3382this item. The group names do not need to be defined before they can be used
3383here.
3384
3385contains=ALL
3386 If the only item in the contains list is "ALL", then all
3387 groups will be accepted inside the item.
3388
3389contains=ALLBUT,{group-name},..
3390 If the first item in the contains list is "ALLBUT", then all
3391 groups will be accepted inside the item, except the ones that
3392 are listed. Example: >
3393 :syntax region Block start="{" end="}" ... contains=ALLBUT,Function
3394
3395contains=TOP
3396 If the first item in the contains list is "TOP", then all
3397 groups will be accepted that don't have the "contained"
3398 argument.
3399contains=TOP,{group-name},..
3400 Like "TOP", but excluding the groups that are listed.
3401
3402contains=CONTAINED
3403 If the first item in the contains list is "CONTAINED", then
3404 all groups will be accepted that have the "contained"
3405 argument.
3406contains=CONTAINED,{group-name},..
3407 Like "CONTAINED", but excluding the groups that are
3408 listed.
3409
3410
3411The {group-name} in the "contains" list can be a pattern. All group names
3412that match the pattern will be included (or excluded, if "ALLBUT" is used).
3413The pattern cannot contain white space or a ','. Example: >
3414 ... contains=Comment.*,Keyw[0-3]
3415The matching will be done at moment the syntax command is executed. Groups
3416that are defined later will not be matched. Also, if the current syntax
3417command defines a new group, it is not matched. Be careful: When putting
3418syntax commands in a file you can't rely on groups NOT being defined, because
3419the file may have been sourced before, and ":syn clear" doesn't remove the
3420group names.
3421
3422The contained groups will also match in the start and end patterns of a
3423region. If this is not wanted, the "matchgroup" argument can be used
3424|:syn-matchgroup|. The "ms=" and "me=" offsets can be used to change the
3425region where contained items do match. Note that this may also limit the
3426area that is highlighted
3427
3428
3429containedin={groupname}... *:syn-containedin*
3430
3431The "containedin" argument is followed by a list of syntax group names. The
3432item will be allowed to begin inside these groups. This works as if the
3433containing item has a "contains=" argument that includes this item.
3434
3435The {groupname}... can be used just like for "contains", as explained above.
3436
3437This is useful when adding a syntax item afterwards. An item can be told to
3438be included inside an already existing item, without changing the definition
3439of that item. For example, to highlight a word in a C comment after loading
3440the C syntax: >
3441 :syn keyword myword HELP containedin=cComment contained
3442Note that "contained" is also used, to avoid that the item matches at the top
3443level.
3444
3445Matches for "containedin" are added to the other places where the item can
3446appear. A "contains" argument may also be added as usual. Don't forget that
3447keywords never contain another item, thus adding them to "containedin" won't
3448work.
3449
3450
3451nextgroup={groupname},.. *:syn-nextgroup*
3452
3453The "nextgroup" argument is followed by a list of syntax group names,
3454separated by commas (just like with "contains", so you can also use patterns).
3455
3456If the "nextgroup" argument is given, the mentioned syntax groups will be
3457tried for a match, after the match or region ends. If none of the groups have
3458a match, highlighting continues normally. If there is a match, this group
3459will be used, even when it is not mentioned in the "contains" field of the
3460current group. This is like giving the mentioned group priority over all
3461other groups. Example: >
3462 :syntax match ccFoobar "Foo.\{-}Bar" contains=ccFoo
3463 :syntax match ccFoo "Foo" contained nextgroup=ccFiller
3464 :syntax region ccFiller start="." matchgroup=ccBar end="Bar" contained
3465
3466This will highlight "Foo" and "Bar" differently, and only when there is a
3467"Bar" after "Foo". In the text line below, "f" shows where ccFoo is used for
3468highlighting, and "bbb" where ccBar is used. >
3469
3470 Foo asdfasd Bar asdf Foo asdf Bar asdf
3471 fff bbb fff bbb
3472
3473Note the use of ".\{-}" to skip as little as possible until the next Bar.
3474when ".*" would be used, the "asdf" in between "Bar" and "Foo" would be
3475highlighted according to the "ccFoobar" group, because the ccFooBar match
3476would include the first "Foo" and the last "Bar" in the line (see |pattern|).
3477
3478
3479skipwhite *:syn-skipwhite*
3480skipnl *:syn-skipnl*
3481skipempty *:syn-skipempty*
3482
3483These arguments are only used in combination with "nextgroup". They can be
3484used to allow the next group to match after skipping some text:
Bram Moolenaardd2a0d82007-05-12 15:07:00 +00003485 skipwhite skip over space and tab characters
Bram Moolenaar071d4272004-06-13 20:20:40 +00003486 skipnl skip over the end of a line
3487 skipempty skip over empty lines (implies a "skipnl")
3488
3489When "skipwhite" is present, the white space is only skipped if there is no
3490next group that matches the white space.
3491
3492When "skipnl" is present, the match with nextgroup may be found in the next
3493line. This only happens when the current item ends at the end of the current
3494line! When "skipnl" is not present, the nextgroup will only be found after
3495the current item in the same line.
3496
3497When skipping text while looking for a next group, the matches for other
3498groups are ignored. Only when no next group matches, other items are tried
3499for a match again. This means that matching a next group and skipping white
3500space and <EOL>s has a higher priority than other items.
3501
3502Example: >
3503 :syn match ifstart "\<if.*" nextgroup=ifline skipwhite skipempty
3504 :syn match ifline "[^ \t].*" nextgroup=ifline skipwhite skipempty contained
3505 :syn match ifline "endif" contained
3506Note that the "[^ \t].*" match matches all non-white text. Thus it would also
3507match "endif". Therefore the "endif" match is put last, so that it takes
3508precedence.
3509Note that this example doesn't work for nested "if"s. You need to add
3510"contains" arguments to make that work (omitted for simplicity of the
3511example).
3512
Bram Moolenaar860cae12010-06-05 23:22:07 +02003513IMPLICIT CONCEAL *:syn-conceal-implicit*
3514
3515:sy[ntax] conceal [on|off]
3516 This defines if the following ":syntax" commands will define keywords,
3517 matches or regions with the "conceal" flag set. After ":syn conceal
3518 on", all subsequent ":syn keyword", ":syn match" or ":syn region"
3519 defined will have the "conceal" flag set implicitly. ":syn conceal
3520 off" returns to the normal state where the "conceal" flag must be
3521 given explicitly.
3522
Bram Moolenaar071d4272004-06-13 20:20:40 +00003523==============================================================================
35247. Syntax patterns *:syn-pattern* *E401* *E402*
3525
3526In the syntax commands, a pattern must be surrounded by two identical
3527characters. This is like it works for the ":s" command. The most common to
3528use is the double quote. But if the pattern contains a double quote, you can
3529use another character that is not used in the pattern. Examples: >
3530 :syntax region Comment start="/\*" end="\*/"
3531 :syntax region String start=+"+ end=+"+ skip=+\\"+
3532
3533See |pattern| for the explanation of what a pattern is. Syntax patterns are
Bram Moolenaar8c8de832008-06-24 22:58:06 +00003534always interpreted like the 'magic' option is set, no matter what the actual
Bram Moolenaar071d4272004-06-13 20:20:40 +00003535value of 'magic' is. And the patterns are interpreted like the 'l' flag is
3536not included in 'cpoptions'. This was done to make syntax files portable and
3537independent of 'compatible' and 'magic' settings.
3538
3539Try to avoid patterns that can match an empty string, such as "[a-z]*".
3540This slows down the highlighting a lot, because it matches everywhere.
3541
3542 *:syn-pattern-offset*
3543The pattern can be followed by a character offset. This can be used to
3544change the highlighted part, and to change the text area included in the
3545match or region (which only matters when trying to match other items). Both
3546are relative to the matched pattern. The character offset for a skip
3547pattern can be used to tell where to continue looking for an end pattern.
3548
3549The offset takes the form of "{what}={offset}"
3550The {what} can be one of seven strings:
3551
3552ms Match Start offset for the start of the matched text
3553me Match End offset for the end of the matched text
3554hs Highlight Start offset for where the highlighting starts
3555he Highlight End offset for where the highlighting ends
3556rs Region Start offset for where the body of a region starts
3557re Region End offset for where the body of a region ends
3558lc Leading Context offset past "leading context" of pattern
3559
3560The {offset} can be:
3561
3562s start of the matched pattern
3563s+{nr} start of the matched pattern plus {nr} chars to the right
3564s-{nr} start of the matched pattern plus {nr} chars to the left
3565e end of the matched pattern
3566e+{nr} end of the matched pattern plus {nr} chars to the right
3567e-{nr} end of the matched pattern plus {nr} chars to the left
3568{nr} (for "lc" only): start matching {nr} chars to the left
3569
3570Examples: "ms=s+1", "hs=e-2", "lc=3".
3571
3572Although all offsets are accepted after any pattern, they are not always
3573meaningful. This table shows which offsets are actually used:
3574
3575 ms me hs he rs re lc ~
3576match item yes yes yes yes - - yes
3577region item start yes - yes - yes - yes
3578region item skip - yes - - - - yes
3579region item end - yes - yes - yes yes
3580
3581Offsets can be concatenated, with a ',' in between. Example: >
3582 :syn match String /"[^"]*"/hs=s+1,he=e-1
3583<
3584 some "string" text
3585 ^^^^^^ highlighted
3586
3587Notes:
3588- There must be no white space between the pattern and the character
3589 offset(s).
3590- The highlighted area will never be outside of the matched text.
3591- A negative offset for an end pattern may not always work, because the end
3592 pattern may be detected when the highlighting should already have stopped.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003593- Before Vim 7.2 the offsets were counted in bytes instead of characters.
3594 This didn't work well for multi-byte characters, so it was changed with the
3595 Vim 7.2 release.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003596- The start of a match cannot be in a line other than where the pattern
3597 matched. This doesn't work: "a\nb"ms=e. You can make the highlighting
3598 start in another line, this does work: "a\nb"hs=e.
3599
3600Example (match a comment but don't highlight the /* and */): >
3601 :syntax region Comment start="/\*"hs=e+1 end="\*/"he=s-1
3602<
3603 /* this is a comment */
3604 ^^^^^^^^^^^^^^^^^^^ highlighted
3605
3606A more complicated Example: >
3607 :syn region Exa matchgroup=Foo start="foo"hs=s+2,rs=e+2 matchgroup=Bar end="bar"me=e-1,he=e-1,re=s-1
3608<
3609 abcfoostringbarabc
3610 mmmmmmmmmmm match
Bram Moolenaar4770d092006-01-12 23:22:24 +00003611 sssrrreee highlight start/region/end ("Foo", "Exa" and "Bar")
Bram Moolenaar071d4272004-06-13 20:20:40 +00003612
3613Leading context *:syn-lc* *:syn-leading* *:syn-context*
3614
3615Note: This is an obsolete feature, only included for backwards compatibility
3616with previous Vim versions. It's now recommended to use the |/\@<=| construct
3617in the pattern.
3618
3619The "lc" offset specifies leading context -- a part of the pattern that must
3620be present, but is not considered part of the match. An offset of "lc=n" will
3621cause Vim to step back n columns before attempting the pattern match, allowing
3622characters which have already been matched in previous patterns to also be
3623used as leading context for this match. This can be used, for instance, to
3624specify that an "escaping" character must not precede the match: >
3625
3626 :syn match ZNoBackslash "[^\\]z"ms=s+1
3627 :syn match WNoBackslash "[^\\]w"lc=1
3628 :syn match Underline "_\+"
3629<
3630 ___zzzz ___wwww
3631 ^^^ ^^^ matches Underline
3632 ^ ^ matches ZNoBackslash
3633 ^^^^ matches WNoBackslash
3634
3635The "ms" offset is automatically set to the same value as the "lc" offset,
3636unless you set "ms" explicitly.
3637
3638
3639Multi-line patterns *:syn-multi-line*
3640
3641The patterns can include "\n" to match an end-of-line. Mostly this works as
3642expected, but there are a few exceptions.
3643
3644When using a start pattern with an offset, the start of the match is not
3645allowed to start in a following line. The highlighting can start in a
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003646following line though. Using the "\zs" item also requires that the start of
3647the match doesn't move to another line.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003648
3649The skip pattern can include the "\n", but the search for an end pattern will
3650continue in the first character of the next line, also when that character is
3651matched by the skip pattern. This is because redrawing may start in any line
3652halfway a region and there is no check if the skip pattern started in a
3653previous line. For example, if the skip pattern is "a\nb" and an end pattern
3654is "b", the end pattern does match in the second line of this: >
3655 x x a
3656 b x x
3657Generally this means that the skip pattern should not match any characters
3658after the "\n".
3659
3660
3661External matches *:syn-ext-match*
3662
3663These extra regular expression items are available in region patterns:
3664
3665 */\z(* */\z(\)* *E50* *E52*
3666 \z(\) Marks the sub-expression as "external", meaning that it is can
3667 be accessed from another pattern match. Currently only usable
3668 in defining a syntax region start pattern.
3669
3670 */\z1* */\z2* */\z3* */\z4* */\z5*
3671 \z1 ... \z9 */\z6* */\z7* */\z8* */\z9* *E66* *E67*
3672 Matches the same string that was matched by the corresponding
3673 sub-expression in a previous start pattern match.
3674
3675Sometimes the start and end patterns of a region need to share a common
3676sub-expression. A common example is the "here" document in Perl and many Unix
3677shells. This effect can be achieved with the "\z" special regular expression
3678items, which marks a sub-expression as "external", in the sense that it can be
3679referenced from outside the pattern in which it is defined. The here-document
3680example, for instance, can be done like this: >
3681 :syn region hereDoc start="<<\z(\I\i*\)" end="^\z1$"
3682
3683As can be seen here, the \z actually does double duty. In the start pattern,
3684it marks the "\(\I\i*\)" sub-expression as external; in the end pattern, it
3685changes the \1 back-reference into an external reference referring to the
3686first external sub-expression in the start pattern. External references can
3687also be used in skip patterns: >
3688 :syn region foo start="start \(\I\i*\)" skip="not end \z1" end="end \z1"
3689
3690Note that normal and external sub-expressions are completely orthogonal and
3691indexed separately; for instance, if the pattern "\z(..\)\(..\)" is applied
3692to the string "aabb", then \1 will refer to "bb" and \z1 will refer to "aa".
3693Note also that external sub-expressions cannot be accessed as back-references
3694within the same pattern like normal sub-expressions. If you want to use one
3695sub-expression as both a normal and an external sub-expression, you can nest
3696the two, as in "\(\z(...\)\)".
3697
3698Note that only matches within a single line can be used. Multi-line matches
3699cannot be referred to.
3700
3701==============================================================================
37028. Syntax clusters *:syn-cluster* *E400*
3703
3704:sy[ntax] cluster {cluster-name} [contains={group-name}..]
3705 [add={group-name}..]
3706 [remove={group-name}..]
3707
3708This command allows you to cluster a list of syntax groups together under a
3709single name.
3710
3711 contains={group-name}..
3712 The cluster is set to the specified list of groups.
3713 add={group-name}..
3714 The specified groups are added to the cluster.
3715 remove={group-name}..
3716 The specified groups are removed from the cluster.
3717
Bram Moolenaar8c8de832008-06-24 22:58:06 +00003718A cluster so defined may be referred to in a contains=.., containedin=..,
3719nextgroup=.., add=.. or remove=.. list with a "@" prefix. You can also use
3720this notation to implicitly declare a cluster before specifying its contents.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003721
3722Example: >
3723 :syntax match Thing "# [^#]\+ #" contains=@ThingMembers
3724 :syntax cluster ThingMembers contains=ThingMember1,ThingMember2
3725
3726As the previous example suggests, modifications to a cluster are effectively
3727retroactive; the membership of the cluster is checked at the last minute, so
3728to speak: >
3729 :syntax keyword A aaa
3730 :syntax keyword B bbb
3731 :syntax cluster AandB contains=A
3732 :syntax match Stuff "( aaa bbb )" contains=@AandB
3733 :syntax cluster AandB add=B " now both keywords are matched in Stuff
3734
3735This also has implications for nested clusters: >
3736 :syntax keyword A aaa
3737 :syntax keyword B bbb
3738 :syntax cluster SmallGroup contains=B
3739 :syntax cluster BigGroup contains=A,@SmallGroup
3740 :syntax match Stuff "( aaa bbb )" contains=@BigGroup
3741 :syntax cluster BigGroup remove=B " no effect, since B isn't in BigGroup
3742 :syntax cluster SmallGroup remove=B " now bbb isn't matched within Stuff
3743
3744==============================================================================
37459. Including syntax files *:syn-include* *E397*
3746
3747It is often useful for one language's syntax file to include a syntax file for
3748a related language. Depending on the exact relationship, this can be done in
3749two different ways:
3750
3751 - If top-level syntax items in the included syntax file are to be
3752 allowed at the top level in the including syntax, you can simply use
3753 the |:runtime| command: >
3754
3755 " In cpp.vim:
3756 :runtime! syntax/c.vim
3757 :unlet b:current_syntax
3758
3759< - If top-level syntax items in the included syntax file are to be
3760 contained within a region in the including syntax, you can use the
3761 ":syntax include" command:
3762
3763:sy[ntax] include [@{grouplist-name}] {file-name}
3764
3765 All syntax items declared in the included file will have the
3766 "contained" flag added. In addition, if a group list is specified,
3767 all top-level syntax items in the included file will be added to
3768 that list. >
3769
3770 " In perl.vim:
3771 :syntax include @Pod <sfile>:p:h/pod.vim
3772 :syntax region perlPOD start="^=head" end="^=cut" contains=@Pod
3773<
3774 When {file-name} is an absolute path (starts with "/", "c:", "$VAR"
3775 or "<sfile>") that file is sourced. When it is a relative path
3776 (e.g., "syntax/pod.vim") the file is searched for in 'runtimepath'.
3777 All matching files are loaded. Using a relative path is
3778 recommended, because it allows a user to replace the included file
3779 with his own version, without replacing the file that does the ":syn
3780 include".
3781
3782==============================================================================
378310. Synchronizing *:syn-sync* *E403* *E404*
3784
3785Vim wants to be able to start redrawing in any position in the document. To
3786make this possible it needs to know the syntax state at the position where
3787redrawing starts.
3788
3789:sy[ntax] sync [ccomment [group-name] | minlines={N} | ...]
3790
3791There are four ways to synchronize:
37921. Always parse from the start of the file.
3793 |:syn-sync-first|
37942. Based on C-style comments. Vim understands how C-comments work and can
3795 figure out if the current line starts inside or outside a comment.
3796 |:syn-sync-second|
37973. Jumping back a certain number of lines and start parsing there.
3798 |:syn-sync-third|
37994. Searching backwards in the text for a pattern to sync on.
3800 |:syn-sync-fourth|
3801
3802 *:syn-sync-maxlines* *:syn-sync-minlines*
3803For the last three methods, the line range where the parsing can start is
3804limited by "minlines" and "maxlines".
3805
3806If the "minlines={N}" argument is given, the parsing always starts at least
3807that many lines backwards. This can be used if the parsing may take a few
3808lines before it's correct, or when it's not possible to use syncing.
3809
3810If the "maxlines={N}" argument is given, the number of lines that are searched
3811for a comment or syncing pattern is restricted to N lines backwards (after
3812adding "minlines"). This is useful if you have few things to sync on and a
3813slow machine. Example: >
3814 :syntax sync ccomment maxlines=500
3815<
3816 *:syn-sync-linebreaks*
3817When using a pattern that matches multiple lines, a change in one line may
3818cause a pattern to no longer match in a previous line. This means has to
3819start above where the change was made. How many lines can be specified with
3820the "linebreaks" argument. For example, when a pattern may include one line
3821break use this: >
3822 :syntax sync linebreaks=1
3823The result is that redrawing always starts at least one line before where a
3824change was made. The default value for "linebreaks" is zero. Usually the
3825value for "minlines" is bigger than "linebreaks".
3826
3827
3828First syncing method: *:syn-sync-first*
3829>
3830 :syntax sync fromstart
3831
3832The file will be parsed from the start. This makes syntax highlighting
3833accurate, but can be slow for long files. Vim caches previously parsed text,
3834so that it's only slow when parsing the text for the first time. However,
3835when making changes some part of the next needs to be parsed again (worst
3836case: to the end of the file).
3837
3838Using "fromstart" is equivalent to using "minlines" with a very large number.
3839
3840
3841Second syncing method: *:syn-sync-second* *:syn-sync-ccomment*
3842
3843For the second method, only the "ccomment" argument needs to be given.
3844Example: >
3845 :syntax sync ccomment
3846
3847When Vim finds that the line where displaying starts is inside a C-style
3848comment, the last region syntax item with the group-name "Comment" will be
3849used. This requires that there is a region with the group-name "Comment"!
3850An alternate group name can be specified, for example: >
3851 :syntax sync ccomment javaComment
3852This means that the last item specified with "syn region javaComment" will be
3853used for the detected C comment region. This only works properly if that
3854region does have a start pattern "\/*" and an end pattern "*\/".
3855
3856The "maxlines" argument can be used to restrict the search to a number of
3857lines. The "minlines" argument can be used to at least start a number of
3858lines back (e.g., for when there is some construct that only takes a few
3859lines, but it hard to sync on).
3860
3861Note: Syncing on a C comment doesn't work properly when strings are used
3862that cross a line and contain a "*/". Since letting strings cross a line
3863is a bad programming habit (many compilers give a warning message), and the
3864chance of a "*/" appearing inside a comment is very small, this restriction
3865is hardly ever noticed.
3866
3867
3868Third syncing method: *:syn-sync-third*
3869
3870For the third method, only the "minlines={N}" argument needs to be given.
3871Vim will subtract {N} from the line number and start parsing there. This
3872means {N} extra lines need to be parsed, which makes this method a bit slower.
3873Example: >
3874 :syntax sync minlines=50
3875
3876"lines" is equivalent to "minlines" (used by older versions).
3877
3878
3879Fourth syncing method: *:syn-sync-fourth*
3880
3881The idea is to synchronize on the end of a few specific regions, called a
3882sync pattern. Only regions can cross lines, so when we find the end of some
3883region, we might be able to know in which syntax item we are. The search
3884starts in the line just above the one where redrawing starts. From there
3885the search continues backwards in the file.
3886
3887This works just like the non-syncing syntax items. You can use contained
3888matches, nextgroup, etc. But there are a few differences:
3889- Keywords cannot be used.
3890- The syntax items with the "sync" keyword form a completely separated group
3891 of syntax items. You can't mix syncing groups and non-syncing groups.
3892- The matching works backwards in the buffer (line by line), instead of
3893 forwards.
3894- A line continuation pattern can be given. It is used to decide which group
3895 of lines need to be searched like they were one line. This means that the
3896 search for a match with the specified items starts in the first of the
3897 consecutive that contain the continuation pattern.
3898- When using "nextgroup" or "contains", this only works within one line (or
3899 group of continued lines).
3900- When using a region, it must start and end in the same line (or group of
3901 continued lines). Otherwise the end is assumed to be at the end of the
3902 line (or group of continued lines).
3903- When a match with a sync pattern is found, the rest of the line (or group of
3904 continued lines) is searched for another match. The last match is used.
3905 This is used when a line can contain both the start end the end of a region
3906 (e.g., in a C-comment like /* this */, the last "*/" is used).
3907
3908There are two ways how a match with a sync pattern can be used:
39091. Parsing for highlighting starts where redrawing starts (and where the
3910 search for the sync pattern started). The syntax group that is expected
3911 to be valid there must be specified. This works well when the regions
3912 that cross lines cannot contain other regions.
39132. Parsing for highlighting continues just after the match. The syntax group
3914 that is expected to be present just after the match must be specified.
3915 This can be used when the previous method doesn't work well. It's much
3916 slower, because more text needs to be parsed.
3917Both types of sync patterns can be used at the same time.
3918
3919Besides the sync patterns, other matches and regions can be specified, to
3920avoid finding unwanted matches.
3921
3922[The reason that the sync patterns are given separately, is that mostly the
3923search for the sync point can be much simpler than figuring out the
3924highlighting. The reduced number of patterns means it will go (much)
3925faster.]
3926
3927 *syn-sync-grouphere* *E393* *E394*
3928 :syntax sync match {sync-group-name} grouphere {group-name} "pattern" ..
3929
3930 Define a match that is used for syncing. {group-name} is the
3931 name of a syntax group that follows just after the match. Parsing
3932 of the text for highlighting starts just after the match. A region
3933 must exist for this {group-name}. The first one defined will be used.
3934 "NONE" can be used for when there is no syntax group after the match.
3935
3936 *syn-sync-groupthere*
3937 :syntax sync match {sync-group-name} groupthere {group-name} "pattern" ..
3938
3939 Like "grouphere", but {group-name} is the name of a syntax group that
3940 is to be used at the start of the line where searching for the sync
3941 point started. The text between the match and the start of the sync
3942 pattern searching is assumed not to change the syntax highlighting.
3943 For example, in C you could search backwards for "/*" and "*/". If
3944 "/*" is found first, you know that you are inside a comment, so the
3945 "groupthere" is "cComment". If "*/" is found first, you know that you
3946 are not in a comment, so the "groupthere" is "NONE". (in practice
3947 it's a bit more complicated, because the "/*" and "*/" could appear
3948 inside a string. That's left as an exercise to the reader...).
3949
3950 :syntax sync match ..
3951 :syntax sync region ..
3952
3953 Without a "groupthere" argument. Define a region or match that is
3954 skipped while searching for a sync point.
3955
Bram Moolenaarc9b4b052006-04-30 18:54:39 +00003956 *syn-sync-linecont*
Bram Moolenaar071d4272004-06-13 20:20:40 +00003957 :syntax sync linecont {pattern}
3958
3959 When {pattern} matches in a line, it is considered to continue in
3960 the next line. This means that the search for a sync point will
3961 consider the lines to be concatenated.
3962
3963If the "maxlines={N}" argument is given too, the number of lines that are
3964searched for a match is restricted to N. This is useful if you have very
3965few things to sync on and a slow machine. Example: >
3966 :syntax sync maxlines=100
3967
3968You can clear all sync settings with: >
3969 :syntax sync clear
3970
3971You can clear specific sync patterns with: >
3972 :syntax sync clear {sync-group-name} ..
3973

397511. Listing syntax items *:syntax* *:sy* *:syn* *:syn-list*
3976
Bram Moolenaar482aaeb2005-09-29 18:26:07 +00003977This command lists all the syntax items: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00003978
3979 :sy[ntax] [list]
3980
3981To show the syntax items for one syntax group: >
3982
3983 :sy[ntax] list {group-name}
3984
Bram Moolenaar24ea3ba2010-09-19 19:01:21 +02003985To list the syntax groups in one cluster: *E392* >
Bram Moolenaar071d4272004-06-13 20:20:40 +00003986
3987 :sy[ntax] list @{cluster-name}
3988
3989See above for other arguments for the ":syntax" command.
3990
3991Note that the ":syntax" command can be abbreviated to ":sy", although ":syn"
3992is mostly used, because it looks better.
3993
3994==============================================================================
399512. Highlight command *:highlight* *:hi* *E28* *E411* *E415*
3996
3997There are three types of highlight groups:
3998- The ones used for specific languages. For these the name starts with the
3999 name of the language. Many of these don't have any attributes, but are
4000 linked to a group of the second type.
4001- The ones used for all syntax languages.
4002- The ones used for the 'highlight' option.
4003 *hitest.vim*
4004You can see all the groups currently active with this command: >
4005 :so $VIMRUNTIME/syntax/hitest.vim
4006This will open a new window containing all highlight group names, displayed
4007in their own color.
4008
4009 *:colo* *:colorscheme* *E185*
Bram Moolenaar00a927d2010-05-14 23:24:24 +02004010:colo[rscheme] Output the name of the currently active color scheme.
4011 This is basically the same as >
4012 :echo g:colors_name
4013< In case g:colors_name has not been defined :colo will
4014 output "default". When compiled without the |+eval|
4015 feature it will output "unknown".
4016
Bram Moolenaar071d4272004-06-13 20:20:40 +00004017:colo[rscheme] {name} Load color scheme {name}. This searches 'runtimepath'
4018 for the file "colors/{name}.vim. The first one that
4019 is found is loaded.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01004020 To see the name of the currently active color scheme: >
Bram Moolenaar00a927d2010-05-14 23:24:24 +02004021 :colo
4022< The name is also stored in the g:colors_name variable.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01004023 Doesn't work recursively, thus you can't use
Bram Moolenaar071d4272004-06-13 20:20:40 +00004024 ":colorscheme" in a color scheme script.
Bram Moolenaarcfbc5ee2004-07-02 15:38:35 +00004025 After the color scheme has been loaded the
4026 |ColorScheme| autocommand event is triggered.

4030:hi[ghlight] List all the current highlight groups that have
4031 attributes set.
4032
4033:hi[ghlight] {group-name}
4034 List one highlight group.
4035
4036:hi[ghlight] clear Reset all highlighting to the defaults. Removes all
4037 highlighting for groups added by the user!
4038 Uses the current value of 'background' to decide which
4039 default colors to use.
4040
4041:hi[ghlight] clear {group-name}
4042:hi[ghlight] {group-name} NONE
4043 Disable the highlighting for one highlight group. It
4044 is _not_ set back to the default colors.
4045
4046:hi[ghlight] [default] {group-name} {key}={arg} ..
4047 Add a highlight group, or change the highlighting for
4048 an existing group.
4049 See |highlight-args| for the {key}={arg} arguments.
4050 See |:highlight-default| for the optional [default]
4051 argument.
4052
4053Normally a highlight group is added once when starting up. This sets the
4054default values for the highlighting. After that, you can use additional
4055highlight commands to change the arguments that you want to set to non-default
4056values. The value "NONE" can be used to switch the value off or go back to
4057the default value.
4058
4059A simple way to change colors is with the |:colorscheme| command. This loads
4060a file with ":highlight" commands such as this: >
4061
4062 :hi Comment gui=bold
4063
4064Note that all settings that are not included remain the same, only the
4065specified field is used, and settings are merged with previous ones. So, the
4066result is like this single command has been used: >
4067 :hi Comment term=bold ctermfg=Cyan guifg=#80a0ff gui=bold
4068<
Bram Moolenaarc9b4b052006-04-30 18:54:39 +00004069 *:highlight-verbose*
Bram Moolenaar661b1822005-07-28 22:36:45 +00004070When listing a highlight group and 'verbose' is non-zero, the listing will
4071also tell where it was last set. Example: >
4072 :verbose hi Comment
4073< Comment xxx term=bold ctermfg=4 guifg=Blue ~

Bram Moolenaar8aff23a2005-08-19 20:40:30 +00004076When ":hi clear" is used then the script where this command is used will be
4077mentioned for the default values. See |:verbose-cmd| for more information.

4080There are three types of terminals for highlighting:
4081term a normal terminal (vt100, xterm)
4082cterm a color terminal (MS-DOS console, color-xterm, these have the "Co"
4083 termcap entry)
4084gui the GUI
4085
4086For each type the highlighting can be given. This makes it possible to use
4087the same syntax file on all terminals, and use the optimal highlighting.

4090
Bram Moolenaar75c50c42005-06-04 22:06:24 +00004091 *bold* *underline* *undercurl*
4092 *inverse* *italic* *standout*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004093term={attr-list} *attr-list* *highlight-term* *E418*
4094 attr-list is a comma separated list (without spaces) of the
4095 following items (in any order):
4096 bold
4097 underline
Bram Moolenaar5409c052005-03-18 20:27:04 +00004098 undercurl not always available
Bram Moolenaar071d4272004-06-13 20:20:40 +00004099 reverse
4100 inverse same as reverse
4101 italic
4102 standout
4103 NONE no attributes used (used to reset it)
4104
4105 Note that "bold" can be used here and by using a bold font. They
4106 have the same effect.
Bram Moolenaar5409c052005-03-18 20:27:04 +00004107 "undercurl" is a curly underline. When "undercurl" is not possible
4108 then "underline" is used. In general "undercurl" is only available in
Bram Moolenaar910f66f2006-04-05 20:41:53 +00004109 the GUI. The color is set with |highlight-guisp|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004110
4111start={term-list} *highlight-start* *E422*
4112stop={term-list} *term-list* *highlight-stop*
4113 These lists of terminal codes can be used to get
4114 non-standard attributes on a terminal.
4115
4116 The escape sequence specified with the "start" argument
4117 is written before the characters in the highlighted
4118 area. It can be anything that you want to send to the
4119 terminal to highlight this area. The escape sequence
4120 specified with the "stop" argument is written after the
4121 highlighted area. This should undo the "start" argument.
4122 Otherwise the screen will look messed up.
4123
4124 The {term-list} can have two forms:
4125
4126 1. A string with escape sequences.
4127 This is any string of characters, except that it can't start with
4128 "t_" and blanks are not allowed. The <> notation is recognized
4129 here, so you can use things like "<Esc>" and "<Space>". Example:
4130 start=<Esc>[27h;<Esc>[<Space>r;
4131
4132 2. A list of terminal codes.
4133 Each terminal code has the form "t_xx", where "xx" is the name of
4134 the termcap entry. The codes have to be separated with commas.
4135 White space is not allowed. Example:
4136 start=t_C1,t_BL
4137 The terminal codes must exist for this to work.
4138
4139
41402. highlight arguments for color terminals
4141
4142cterm={attr-list} *highlight-cterm*
4143 See above for the description of {attr-list} |attr-list|.
4144 The "cterm" argument is likely to be different from "term", when
4145 colors are used. For example, in a normal terminal comments could
4146 be underlined, in a color terminal they can be made Blue.
4147 Note: Many terminals (e.g., DOS console) can't mix these attributes
4148 with coloring. Use only one of "cterm=" OR "ctermfg=" OR "ctermbg=".
4149
4150ctermfg={color-nr} *highlight-ctermfg* *E421*
4151ctermbg={color-nr} *highlight-ctermbg*
4152 The {color-nr} argument is a color number. Its range is zero to
4153 (not including) the number given by the termcap entry "Co".
4154 The actual color with this number depends on the type of terminal
4155 and its settings. Sometimes the color also depends on the settings of
4156 "cterm". For example, on some systems "cterm=bold ctermfg=3" gives
4157 another color, on others you just get color 3.
4158
4159 For an xterm this depends on your resources, and is a bit
4160 unpredictable. See your xterm documentation for the defaults. The
4161 colors for a color-xterm can be changed from the .Xdefaults file.
4162 Unfortunately this means that it's not possible to get the same colors
4163 for each user. See |xterm-color| for info about color xterms.
4164
4165 The MSDOS standard colors are fixed (in a console window), so these
4166 have been used for the names. But the meaning of color names in X11
4167 are fixed, so these color settings have been used, to make the
4168 highlighting settings portable (complicated, isn't it?). The
4169 following names are recognized, with the color number used:
4170
4171 *cterm-colors*
4172 NR-16 NR-8 COLOR NAME ~
4173 0 0 Black
4174 1 4 DarkBlue
4175 2 2 DarkGreen
4176 3 6 DarkCyan
4177 4 1 DarkRed
4178 5 5 DarkMagenta
4179 6 3 Brown, DarkYellow
4180 7 7 LightGray, LightGrey, Gray, Grey
4181 8 0* DarkGray, DarkGrey
4182 9 4* Blue, LightBlue
4183 10 2* Green, LightGreen
4184 11 6* Cyan, LightCyan
4185 12 1* Red, LightRed
4186 13 5* Magenta, LightMagenta
4187 14 3* Yellow, LightYellow
4188 15 7* White
4189
4190 The number under "NR-16" is used for 16-color terminals ('t_Co'
4191 greater than or equal to 16). The number under "NR-8" is used for
4192 8-color terminals ('t_Co' less than 16). The '*' indicates that the
4193 bold attribute is set for ctermfg. In many 8-color terminals (e.g.,
4194 "linux"), this causes the bright colors to appear. This doesn't work
4195 for background colors! Without the '*' the bold attribute is removed.
4196 If you want to set the bold attribute in a different way, put a
4197 "cterm=" argument AFTER the "ctermfg=" or "ctermbg=" argument. Or use
4198 a number instead of a color name.
4199
4200 The case of the color names is ignored.
4201 Note that for 16 color ansi style terminals (including xterms), the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004202 numbers in the NR-8 column is used. Here '*' means 'add 8' so that Blue
Bram Moolenaar071d4272004-06-13 20:20:40 +00004203 is 12, DarkGray is 8 etc.
4204
4205 Note that for some color terminals these names may result in the wrong
4206 colors!
4207
4208 *:hi-normal-cterm*
4209 When setting the "ctermfg" or "ctermbg" colors for the Normal group,
4210 these will become the colors used for the non-highlighted text.
4211 Example: >
4212 :highlight Normal ctermfg=grey ctermbg=darkblue
4213< When setting the "ctermbg" color for the Normal group, the
4214 'background' option will be adjusted automatically. This causes the
4215 highlight groups that depend on 'background' to change! This means
4216 you should set the colors for Normal first, before setting other
4217 colors.
4218 When a colorscheme is being used, changing 'background' causes it to
4219 be reloaded, which may reset all colors (including Normal). First
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01004220 delete the "g:colors_name" variable when you don't want this.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004221
4222 When you have set "ctermfg" or "ctermbg" for the Normal group, Vim
4223 needs to reset the color when exiting. This is done with the "op"
4224 termcap entry |t_op|. If this doesn't work correctly, try setting the
4225 't_op' option in your .vimrc.
4226 *E419* *E420*
4227 When Vim knows the normal foreground and background colors, "fg" and
4228 "bg" can be used as color names. This only works after setting the
4229 colors for the Normal group and for the MS-DOS console. Example, for
4230 reverse video: >
4231 :highlight Visual ctermfg=bg ctermbg=fg
4232< Note that the colors are used that are valid at the moment this
4233 command are given. If the Normal group colors are changed later, the
4234 "fg" and "bg" colors will not be adjusted.
4235
4236
42373. highlight arguments for the GUI
4238
4239gui={attr-list} *highlight-gui*
4240 These give the attributes to use in the GUI mode.
4241 See |attr-list| for a description.
4242 Note that "bold" can be used here and by using a bold font. They
4243 have the same effect.
4244 Note that the attributes are ignored for the "Normal" group.
4245
4246font={font-name} *highlight-font*
4247 font-name is the name of a font, as it is used on the system Vim
4248 runs on. For X11 this is a complicated name, for example: >
4249 font=-misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1
4250<
4251 The font-name "NONE" can be used to revert to the default font.
4252 When setting the font for the "Normal" group, this becomes the default
4253 font (until the 'guifont' option is changed; the last one set is
4254 used).
4255 The following only works with Motif and Athena, not with other GUIs:
4256 When setting the font for the "Menu" group, the menus will be changed.
4257 When setting the font for the "Tooltip" group, the tooltips will be
4258 changed.
4259 All fonts used, except for Menu and Tooltip, should be of the same
4260 character size as the default font! Otherwise redrawing problems will
4261 occur.
4262
4263guifg={color-name} *highlight-guifg*
4264guibg={color-name} *highlight-guibg*
Bram Moolenaar5409c052005-03-18 20:27:04 +00004265guisp={color-name} *highlight-guisp*
4266 These give the foreground (guifg), background (guibg) and special
Bram Moolenaar7df351e2006-01-23 22:30:28 +00004267 (guisp) color to use in the GUI. "guisp" is used for undercurl.
4268 There are a few special names:
Bram Moolenaar071d4272004-06-13 20:20:40 +00004269 NONE no color (transparent)
4270 bg use normal background color
4271 background use normal background color
4272 fg use normal foreground color
4273 foreground use normal foreground color
4274 To use a color name with an embedded space or other special character,
4275 put it in single quotes. The single quote cannot be used then.
4276 Example: >
4277 :hi comment guifg='salmon pink'
4278<
4279 *gui-colors*
4280 Suggested color names (these are available on most systems):
4281 Red LightRed DarkRed
4282 Green LightGreen DarkGreen SeaGreen
4283 Blue LightBlue DarkBlue SlateBlue
4284 Cyan LightCyan DarkCyan
4285 Magenta LightMagenta DarkMagenta
4286 Yellow LightYellow Brown DarkYellow
4287 Gray LightGray DarkGray
4288 Black White
4289 Orange Purple Violet
4290
4291 In the Win32 GUI version, additional system colors are available. See
4292 |win32-colors|.
4293
4294 You can also specify a color by its Red, Green and Blue values.
4295 The format is "#rrggbb", where
4296 "rr" is the Red value
Bram Moolenaar071d4272004-06-13 20:20:40 +00004297 "gg" is the Green value
Bram Moolenaar5409c052005-03-18 20:27:04 +00004298 "bb" is the Blue value
Bram Moolenaar071d4272004-06-13 20:20:40 +00004299 All values are hexadecimal, range from "00" to "ff". Examples: >
4300 :highlight Comment guifg=#11f0c3 guibg=#ff00ff
4301<
4302 *highlight-groups* *highlight-default*
4303These are the default highlighting groups. These groups are used by the
4304'highlight' option default. Note that the highlighting depends on the value
4305of 'background'. You can see the current settings with the ":highlight"
4306command.

4415 *hl-WarningMsg*
4416WarningMsg warning messages
4417 *hl-WildMenu*
4418WildMenu current match in 'wildmenu' completion

Bram Moolenaarf75a9632005-09-13 21:20:47 +00004420 *hl-User1* *hl-User1..9* *hl-User9*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004421The 'statusline' syntax allows the use of 9 different highlights in the
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004422statusline and ruler (via 'rulerformat'). The names are User1 to User9.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004423
Bram Moolenaar8c8de832008-06-24 22:58:06 +00004424For the GUI you can use the following groups to set the colors for the menu,
Bram Moolenaar071d4272004-06-13 20:20:40 +00004425scrollbars and tooltips. They don't have defaults. This doesn't work for the
4426Win32 GUI. Only three highlight arguments have any effect here: font, guibg,
4427and guifg.
4428
4429 *hl-Menu*
4430Menu Current font, background and foreground colors of the menus.
4431 Also used for the toolbar.
4432 Applicable highlight arguments: font, guibg, guifg.
4433
4434 NOTE: For Motif and Athena the font argument actually
4435 specifies a fontset at all times, no matter if 'guifontset' is
4436 empty, and as such it is tied to the current |:language| when
4437 set.
4438
4439 *hl-Scrollbar*
4440Scrollbar Current background and foreground of the main window's
4441 scrollbars.
4442 Applicable highlight arguments: guibg, guifg.
4443
4444 *hl-Tooltip*
4445Tooltip Current font, background and foreground of the tooltips.
4446 Applicable highlight arguments: font, guibg, guifg.
4447
4448 NOTE: For Motif and Athena the font argument actually
4449 specifies a fontset at all times, no matter if 'guifontset' is
4450 empty, and as such it is tied to the current |:language| when
4451 set.
4452
4453==============================================================================
445413. Linking groups *:hi-link* *:highlight-link* *E412* *E413*
4455
4456When you want to use the same highlighting for several syntax groups, you
4457can do this more easily by linking the groups into one common highlight
4458group, and give the color attributes only for that group.
4459
4460To set a link:
4461
4462 :hi[ghlight][!] [default] link {from-group} {to-group}
4463
4464To remove a link:
4465
4466 :hi[ghlight][!] [default] link {from-group} NONE
4467
4468Notes: *E414*
4469- If the {from-group} and/or {to-group} doesn't exist, it is created. You
4470 don't get an error message for a non-existing group.
4471- As soon as you use a ":highlight" command for a linked group, the link is
4472 removed.
4473- If there are already highlight settings for the {from-group}, the link is
4474 not made, unless the '!' is given. For a ":highlight link" command in a
4475 sourced file, you don't get an error message. This can be used to skip
4476 links for groups that already have settings.
4477
4478 *:hi-default* *:highlight-default*
4479The [default] argument is used for setting the default highlighting for a
4480group. If highlighting has already been specified for the group the command
4481will be ignored. Also when there is an existing link.
4482
4483Using [default] is especially useful to overrule the highlighting of a
4484specific syntax file. For example, the C syntax file contains: >
4485 :highlight default link cComment Comment
4486If you like Question highlighting for C comments, put this in your vimrc file: >
4487 :highlight link cComment Question
4488Without the "default" in the C syntax file, the highlighting would be
4489overruled when the syntax file is loaded.
4490
4491==============================================================================
449214. Cleaning up *:syn-clear* *E391*
4493
4494If you want to clear the syntax stuff for the current buffer, you can use this
4495command: >
4496 :syntax clear
4497
4498This command should be used when you want to switch off syntax highlighting,
4499or when you want to switch to using another syntax. It's normally not needed
4500in a syntax file itself, because syntax is cleared by the autocommands that
4501load the syntax file.
4502The command also deletes the "b:current_syntax" variable, since no syntax is
4503loaded after this command.
4504
4505If you want to disable syntax highlighting for all buffers, you need to remove
4506the autocommands that load the syntax files: >
4507 :syntax off
4508
4509What this command actually does, is executing the command >
4510 :source $VIMRUNTIME/syntax/nosyntax.vim
4511See the "nosyntax.vim" file for details. Note that for this to work
4512$VIMRUNTIME must be valid. See |$VIMRUNTIME|.
4513
4514To clean up specific syntax groups for the current buffer: >
4515 :syntax clear {group-name} ..
4516This removes all patterns and keywords for {group-name}.
4517
4518To clean up specific syntax group lists for the current buffer: >
4519 :syntax clear @{grouplist-name} ..
4520This sets {grouplist-name}'s contents to an empty list.
4521
4522 *:syntax-reset* *:syn-reset*
4523If you have changed the colors and messed them up, use this command to get the
4524defaults back: >
4525
4526 :syntax reset
4527
4528This doesn't change the colors for the 'highlight' option.
4529
4530Note that the syntax colors that you set in your vimrc file will also be reset
4531back to their Vim default.
4532Note that if you are using a color scheme, the colors defined by the color
4533scheme for syntax highlighting will be lost.
4534
4535What this actually does is: >
4536
4537 let g:syntax_cmd = "reset"
4538 runtime! syntax/syncolor.vim
4539
4540Note that this uses the 'runtimepath' option.
4541
4542 *syncolor*
4543If you want to use different colors for syntax highlighting, you can add a Vim
4544script file to set these colors. Put this file in a directory in
4545'runtimepath' which comes after $VIMRUNTIME, so that your settings overrule
4546the default colors. This way these colors will be used after the ":syntax
4547reset" command.
4548
4549For Unix you can use the file ~/.vim/after/syntax/syncolor.vim. Example: >
4550
4551 if &background == "light"
4552 highlight comment ctermfg=darkgreen guifg=darkgreen
4553 else
4554 highlight comment ctermfg=green guifg=green
4555 endif
4556
Bram Moolenaarc0197e22004-09-13 20:26:32 +00004557 *E679*
4558Do make sure this syncolor.vim script does not use a "syntax on", set the
4559'background' option or uses a "colorscheme" command, because it results in an
4560endless loop.
4561
Bram Moolenaar071d4272004-06-13 20:20:40 +00004562Note that when a color scheme is used, there might be some confusion whether
4563your defined colors are to be used or the colors from the scheme. This
4564depends on the color scheme file. See |:colorscheme|.
4565
4566 *syntax_cmd*
4567The "syntax_cmd" variable is set to one of these values when the
4568syntax/syncolor.vim files are loaded:
4569 "on" ":syntax on" command. Highlight colors are overruled but
4570 links are kept
4571 "enable" ":syntax enable" command. Only define colors for groups that
4572 don't have highlighting yet. Use ":syntax default".
4573 "reset" ":syntax reset" command or loading a color scheme. Define all
4574 the colors.
4575 "skip" Don't define colors. Used to skip the default settings when a
4576 syncolor.vim file earlier in 'runtimepath' has already set
4577 them.
4578
4579==============================================================================
458015. Highlighting tags *tag-highlight*
4581
4582If you want to highlight all the tags in your file, you can use the following
4583mappings.
4584
4585 <F11> -- Generate tags.vim file, and highlight tags.
4586 <F12> -- Just highlight tags based on existing tags.vim file.
4587>
4588 :map <F11> :sp tags<CR>:%s/^\([^ :]*:\)\=\([^ ]*\).*/syntax keyword Tag \2/<CR>:wq! tags.vim<CR>/^<CR><F12>
4589 :map <F12> :so tags.vim<CR>
4590
4591WARNING: The longer the tags file, the slower this will be, and the more
4592memory Vim will consume.
4593
4594Only highlighting typedefs, unions and structs can be done too. For this you
4595must use Exuberant ctags (found at http://ctags.sf.net).
4596
4597Put these lines in your Makefile:
4598
4599# Make a highlight file for types. Requires Exuberant ctags and awk
4600types: types.vim
4601types.vim: *.[ch]
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00004602 ctags --c-kinds=gstu -o- *.[ch] |\
Bram Moolenaar071d4272004-06-13 20:20:40 +00004603 awk 'BEGIN{printf("syntax keyword Type\t")}\
4604 {printf("%s ", $$1)}END{print ""}' > $@
4605
4606And put these lines in your .vimrc: >
4607
4608 " load the types.vim highlighting file, if it exists
4609 autocmd BufRead,BufNewFile *.[ch] let fname = expand('<afile>:p:h') . '/types.vim'
4610 autocmd BufRead,BufNewFile *.[ch] if filereadable(fname)
4611 autocmd BufRead,BufNewFile *.[ch] exe 'so ' . fname
4612 autocmd BufRead,BufNewFile *.[ch] endif
4613
4614==============================================================================
Bram Moolenaar860cae12010-06-05 23:22:07 +0200461516. Window-local syntax *:ownsyntax*
4616
4617Normally all windows on a buffer share the same syntax settings. It is
4618possible, however, to set a particular window on a file to have its own
4619private syntax setting. A possible example would be to edit LaTeX source
4620with conventional highlighting in one window, while seeing the same source
4621highlighted differently (so as to hide control sequences and indicate bold,
4622italic etc regions) in another. The 'scrollbind' option is useful here.
4623
4624To set the current window to have the syntax "foo", separately from all other
4625windows on the buffer: >
4626 :ownsyntax foo
Bram Moolenaardebe25a2010-06-06 17:41:24 +02004627< *w:current_syntax*
4628This will set the "w:current_syntax" variable to "foo". The value of
4629"b:current_syntax" does not change. This is implemented by saving and
4630restoring "b:current_syntax", since the syntax files do set
4631"b:current_syntax". The value set by the syntax file is assigned to
4632"w:current_syntax".
Bram Moolenaar860cae12010-06-05 23:22:07 +02004633
4634Once a window has its own syntax, syntax commands executed from other windows
4635on the same buffer (including :syntax clear) have no effect. Conversely,
4636syntax commands executed from that window do not effect other windows on the
4637same buffer.
4638
Bram Moolenaardebe25a2010-06-06 17:41:24 +02004639A window with its own syntax reverts to normal behavior when another buffer
4640is loaded into that window or the file is reloaded.
4641When splitting the window, the new window will use the original syntax.

4643==============================================================================
Bram Moolenaar24ea3ba2010-09-19 19:01:21 +0200464417. Color xterms *xterm-color* *color-xterm*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004645
4646Most color xterms have only eight colors. If you don't get colors with the
4647default setup, it should work with these lines in your .vimrc: >
4648 :if &term =~ "xterm"
4649 : if has("terminfo")
4650 : set t_Co=8
4651 : set t_Sf=<Esc>[3%p1%dm
4652 : set t_Sb=<Esc>[4%p1%dm
4653 : else
4654 : set t_Co=8
4655 : set t_Sf=<Esc>[3%dm
4656 : set t_Sb=<Esc>[4%dm
4657 : endif
4658 :endif
4659< [<Esc> is a real escape, type CTRL-V <Esc>]
4660
4661You might want to change the first "if" to match the name of your terminal,
4662e.g. "dtterm" instead of "xterm".
4663
4664Note: Do these settings BEFORE doing ":syntax on". Otherwise the colors may
4665be wrong.
4666 *xiterm* *rxvt*
4667The above settings have been mentioned to work for xiterm and rxvt too.
4668But for using 16 colors in an rxvt these should work with terminfo: >
4669 :set t_AB=<Esc>[%?%p1%{8}%<%t25;%p1%{40}%+%e5;%p1%{32}%+%;%dm
4670 :set t_AF=<Esc>[%?%p1%{8}%<%t22;%p1%{30}%+%e1;%p1%{22}%+%;%dm
4671<
4672 *colortest.vim*
4673To test your color setup, a file has been included in the Vim distribution.
Bram Moolenaarf740b292006-02-16 22:11:02 +00004674To use it, execute this command: >
4675 :runtime syntax/colortest.vim
Bram Moolenaar071d4272004-06-13 20:20:40 +00004676
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004677Some versions of xterm (and other terminals, like the Linux console) can
Bram Moolenaar071d4272004-06-13 20:20:40 +00004678output lighter foreground colors, even though the number of colors is defined
4679at 8. Therefore Vim sets the "cterm=bold" attribute for light foreground
4680colors, when 't_Co' is 8.
4681
4682 *xfree-xterm*
4683To get 16 colors or more, get the newest xterm version (which should be
Bram Moolenaar13fcaaf2005-04-15 21:13:42 +00004684included with XFree86 3.3 and later). You can also find the latest version
Bram Moolenaar071d4272004-06-13 20:20:40 +00004685at: >
4686 http://invisible-island.net/xterm/xterm.html
4687Here is a good way to configure it. This uses 88 colors and enables the
4688termcap-query feature, which allows Vim to ask the xterm how many colors it
4689supports. >
4690 ./configure --disable-bold-color --enable-88-color --enable-tcap-query
4691If you only get 8 colors, check the xterm compilation settings.
4692(Also see |UTF8-xterm| for using this xterm with UTF-8 character encoding).
4693
4694This xterm should work with these lines in your .vimrc (for 16 colors): >
4695 :if has("terminfo")
4696 : set t_Co=16
4697 : set t_AB=<Esc>[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{92}%+%;%dm
4698 : set t_AF=<Esc>[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{82}%+%;%dm
4699 :else
4700 : set t_Co=16
4701 : set t_Sf=<Esc>[3%dm
4702 : set t_Sb=<Esc>[4%dm
4703 :endif
4704< [<Esc> is a real escape, type CTRL-V <Esc>]
4705
4706Without |+terminfo|, Vim will recognize these settings, and automatically
4707translate cterm colors of 8 and above to "<Esc>[9%dm" and "<Esc>[10%dm".
4708Colors above 16 are also translated automatically.
4709
4710For 256 colors this has been reported to work: >
4711
4712 :set t_AB=<Esc>[48;5;%dm
4713 :set t_AF=<Esc>[38;5;%dm
4714
4715Or just set the TERM environment variable to "xterm-color" or "xterm-16color"
4716and try if that works.
4717
4718You probably want to use these X resources (in your ~/.Xdefaults file):
4719 XTerm*color0: #000000
4720 XTerm*color1: #c00000
4721 XTerm*color2: #008000
4722 XTerm*color3: #808000
4723 XTerm*color4: #0000c0
4724 XTerm*color5: #c000c0
4725 XTerm*color6: #008080
4726 XTerm*color7: #c0c0c0
4727 XTerm*color8: #808080
4728 XTerm*color9: #ff6060
4729 XTerm*color10: #00ff00
4730 XTerm*color11: #ffff00
4731 XTerm*color12: #8080ff
4732 XTerm*color13: #ff40ff
4733 XTerm*color14: #00ffff
4734 XTerm*color15: #ffffff
4735 Xterm*cursorColor: Black
4736
4737[Note: The cursorColor is required to work around a bug, which changes the
4738cursor color to the color of the last drawn text. This has been fixed by a
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00004739newer version of xterm, but not everybody is using it yet.]
Bram Moolenaar071d4272004-06-13 20:20:40 +00004740
4741To get these right away, reload the .Xdefaults file to the X Option database
4742Manager (you only need to do this when you just changed the .Xdefaults file): >
4743 xrdb -merge ~/.Xdefaults
4744<
4745 *xterm-blink* *xterm-blinking-cursor*
4746To make the cursor blink in an xterm, see tools/blink.c. Or use Thomas
4747Dickey's xterm above patchlevel 107 (see above for where to get it), with
4748these resources:
4749 XTerm*cursorBlink: on
4750 XTerm*cursorOnTime: 400
4751 XTerm*cursorOffTime: 250
4752 XTerm*cursorColor: White
4753
4754 *hpterm-color*
Bram Moolenaarc81e5e72007-05-05 18:24:42 +00004755These settings work (more or less) for an hpterm, which only supports 8
Bram Moolenaar071d4272004-06-13 20:20:40 +00004756foreground colors: >
4757 :if has("terminfo")
4758 : set t_Co=8
4759 : set t_Sf=<Esc>[&v%p1%dS
4760 : set t_Sb=<Esc>[&v7S
4761 :else
4762 : set t_Co=8
4763 : set t_Sf=<Esc>[&v%dS
4764 : set t_Sb=<Esc>[&v7S
4765 :endif
4766< [<Esc> is a real escape, type CTRL-V <Esc>]
4767
4768 *Eterm* *enlightened-terminal*
4769These settings have been reported to work for the Enlightened terminal
4770emulator, or Eterm. They might work for all xterm-like terminals that use the
4771bold attribute to get bright colors. Add an ":if" like above when needed. >
4772 :set t_Co=16
4773 :set t_AF=^[[%?%p1%{8}%<%t3%p1%d%e%p1%{22}%+%d;1%;m
4774 :set t_AB=^[[%?%p1%{8}%<%t4%p1%d%e%p1%{32}%+%d;1%;m
4775<
4776 *TTpro-telnet*
4777These settings should work for TTpro telnet. Tera Term Pro is a freeware /
4778open-source program for MS-Windows. >
4779 set t_Co=16
4780 set t_AB=^[[%?%p1%{8}%<%t%p1%{40}%+%e%p1%{32}%+5;%;%dm
4781 set t_AF=^[[%?%p1%{8}%<%t%p1%{30}%+%e%p1%{22}%+1;%;%dm
4782Also make sure TTpro's Setup / Window / Full Color is enabled, and make sure
4783that Setup / Font / Enable Bold is NOT enabled.
