37 ;; Font-lock-mode is a minor mode that causes your comments to be
|
|
|
38 ;; displayed in one face, strings in another, reserved words in another,
|
|
|
39 ;; documentation strings in another, and so on.
|
|
|
40 ;;
|
|
|
41 ;; Comments will be displayed in `font-lock-comment-face'.
|
|
|
42 ;; Strings will be displayed in `font-lock-string-face'.
|
|
|
43 ;; Doc strings will be displayed in `font-lock-doc-string-face'.
|
|
|
44 ;; Function and variable names (in their defining forms) will be
|
|
|
45 ;; displayed in `font-lock-function-name-face'.
|
|
|
46 ;; Reserved words will be displayed in `font-lock-keyword-face'.
|
|
|
47 ;;
|
|
|
48 ;; Don't let the name fool you: you can highlight things using different
|
|
|
49 ;; colors or background stipples instead of fonts, though that is not the
|
|
|
50 ;; default. See the variables `font-lock-use-colors' and
|
|
|
51 ;; `font-lock-use-fonts' for broad control over this, or see the
|
|
|
52 ;; documentation on faces and how to change their attributes for
|
|
|
53 ;; fine-grained control.
|
|
|
54 ;;
|
|
|
55 ;; To make the text you type be fontified, use M-x font-lock-mode. When
|
|
|
56 ;; this minor mode is on, the fonts of the current line will be updated
|
|
|
57 ;; with every insertion or deletion.
|
|
|
58 ;;
|
|
|
59 ;; By default, font-lock will automatically put newly loaded files
|
|
|
60 ;; into font-lock-mode if it knows about the file's mode. See the
|
|
|
61 ;; variables `font-lock-auto-fontify', `font-lock-mode-enable-list',
|
|
|
62 ;; and `font-lock-mode-disable-list' for control over this.
|
|
|
63 ;;
|
|
|
64 ;; The `font-lock-keywords' variable defines other patterns to highlight.
|
|
|
65 ;; The default font-lock-mode-hook sets it to the value of the variables
|
|
|
66 ;; lisp-font-lock-keywords, c-font-lock-keywords, etc, as appropriate.
|
|
|
67 ;; The easiest way to change the highlighting patterns is to change the
|
|
|
68 ;; values of c-font-lock-keywords and related variables. See the doc
|
|
|
69 ;; string of the variable `font-lock-keywords' for the appropriate syntax.
|
|
|
70 ;;
|
|
|
71 ;; The default value for `lisp-font-lock-keywords' is the value of the variable
|
|
|
72 ;; `lisp-font-lock-keywords-1'. You may like `lisp-font-lock-keywords-2'
|
|
|
73 ;; better; it highlights many more words, but is slower and makes your buffers
|
|
|
74 ;; be very visually noisy.
|
|
|
75 ;;
|
|
|
76 ;; The same is true of `c-font-lock-keywords-1' and `c-font-lock-keywords-2';
|
|
|
77 ;; the former is subdued, the latter is loud.
|
|
|
78 ;;
|
|
|
79 ;; You can make font-lock default to the gaudier variety of keyword
|
|
|
80 ;; highlighting by setting the variable `font-lock-maximum-decoration'
|
|
|
81 ;; before loading font-lock, or by calling the functions
|
|
|
82 ;; `font-lock-use-default-maximal-decoration' or
|
|
|
83 ;; `font-lock-use-default-minimal-decoration'.
|
|
|
84 ;;
|
|
|
85 ;; On a Sparc10, the initial fontification takes about 6 seconds for a typical
|
|
|
86 ;; 140k file of C code, using the default configuration. The actual speed
|
|
|
87 ;; depends heavily on the type of code in the file, and how many non-syntactic
|
|
|
88 ;; patterns match; for example, Xlib.h takes 23 seconds for 101k, because many
|
|
|
89 ;; patterns match in it. You can speed this up substantially by removing some
|
|
|
90 ;; of the patterns that are highlighted by default. Fontifying lisp code is
|
|
|
91 ;; significantly faster, because lisp has a more regular syntax than C, so the
|
|
|
92 ;; regular expressions don't have to be as complicated.
|
|
|
93 ;;
|
|
|
94 ;; It's called font-lock-mode here because on the Lispms it was called
|
|
|
95 ;; "Electric Font Lock Mode." It was called that because there was an older
|
|
|
96 ;; mode called "Electric Caps Lock Mode" which had the function of causing all
|
|
|
97 ;; of your source code to be in upper case except for strings and comments,
|
|
|
98 ;; without you having to blip the caps lock key by hand all the time (thus the
|
|
|
99 ;; "electric", as in `electric-c-brace'.)
|
|
|
100
|
|
|
101 ;; See also the related packages `fast-lock' and `lazy-lock'. Both
|
|
|
102 ;; attempt to speed up the initial fontification. `fast-lock' saves
|
|
|
103 ;; the fontification info when you exit Emacs and reloads it next time
|
|
|
104 ;; you load the file, so that the file doesn't have to be fontified
|
|
|
105 ;; again. `lazy-lock' does "lazy" fontification -- i.e. it only
|
|
|
106 ;; fontifies the text as it becomes visible rather than fontifying
|
|
|
107 ;; the whole file when it's first loaded in.
|
|
|
108
|
|
|
109 ;; Further comments from the FSF:
|
|
|
110
|
|
|
111 ;; Nasty regexps of the form "bar\\(\\|lo\\)\\|f\\(oo\\|u\\(\\|bar\\)\\)\\|lo"
|
|
|
112 ;; are made thusly: (regexp-opt '("foo" "fu" "fubar" "bar" "barlo" "lo")) for
|
|
|
113 ;; efficiency.
|
|
|
114
|
|
|
115 ;; What is fontification for? You might say, "It's to make my code look nice."
|
|
|
116 ;; I think it should be for adding information in the form of cues. These cues
|
|
|
117 ;; should provide you with enough information to both (a) distinguish between
|
|
|
118 ;; different items, and (b) identify the item meanings, without having to read
|
|
|
119 ;; the items and think about it. Therefore, fontification allows you to think
|
|
|
120 ;; less about, say, the structure of code, and more about, say, why the code
|
|
|
121 ;; doesn't work. Or maybe it allows you to think less and drift off to sleep.
|
|
|
122 ;;
|
|
|
123 ;; So, here are my opinions/advice/guidelines:
|
|
|
124 ;;
|
|
|
125 ;; - Use the same face for the same conceptual object, across all modes.
|
|
|
126 ;; i.e., (b) above, all modes that have items that can be thought of as, say,
|
|
|
127 ;; keywords, should be highlighted with the same face, etc.
|
|
|
128 ;; - Keep the faces distinct from each other as far as possible.
|
|
|
129 ;; i.e., (a) above.
|
|
|
130 ;; - Make the face attributes fit the concept as far as possible.
|
|
|
131 ;; i.e., function names might be a bold color such as blue, comments might
|
|
|
132 ;; be a bright color such as red, character strings might be brown, because,
|
|
|
133 ;; err, strings are brown (that was not the reason, please believe me).
|
|
|
134 ;; - Don't use a non-nil OVERRIDE unless you have a good reason.
|
|
|
135 ;; Only use OVERRIDE for special things that are easy to define, such as the
|
|
|
136 ;; way `...' quotes are treated in strings and comments in Emacs Lisp mode.
|
|
|
137 ;; Don't use it to, say, highlight keywords in commented out code or strings.
|
|
|
138 ;; - Err, that's it.

321 "A list of the keywords to highlight.
|
|
|
322 Each element should be of the form:
|
|
|
323
|
|
|
324 MATCHER
|
|
|
325 (MATCHER . MATCH)
|
|
|
326 (MATCHER . FACENAME)

327 (MATCHER . HIGHLIGHT)

|
328 (MATCHER HIGHLIGHT ...)
|
|
|
329 (eval . FORM)
|
|
|
330
|
|
|
331 where HIGHLIGHT should be either MATCH-HIGHLIGHT or MATCH-ANCHORED.
|
|
|
332
|
|
|
333 FORM is an expression, whose value should be a keyword element,
|
|
|
334 evaluated when the keyword is (first) used in a buffer. This feature
|
|
|
335 can be used to provide a keyword that can only be generated when Font
|
|
|
336 Lock mode is actually turned on.
|
|
|
337
|
|
|
338 For highlighting single items, typically only MATCH-HIGHLIGHT is required.
|
|
|
339 However, if an item or (typically) items is to be highlighted following the
|
|
|
340 instance of another item (the anchor) then MATCH-ANCHORED may be required.
|
|
|
341
|
|
|
342 MATCH-HIGHLIGHT should be of the form:
|
|
|
343
|
|
|
344 (MATCH FACENAME OVERRIDE LAXMATCH)
|
|
|
345
|
|
|
346 Where MATCHER can be either the regexp to search for, a variable
|
|
|
347 containing the regexp to search for, or the function to call to make
|
|
|
348 the search (called with one argument, the limit of the search). MATCH
|
|
|
349 is the subexpression of MATCHER to be highlighted. FACENAME is either
|
|
|
350 a symbol naming a face, or an expression whose value is the face name
|
|
|
351 to use. If you want FACENAME to be a symbol that evaluates to a face,
|
|
|
352 use a form like \"(progn sym)\".
|
|
|
353
|
|
|
354 OVERRIDE and LAXMATCH are flags. If OVERRIDE is t, existing fontification may
|
|
|
355 be overwritten. If `keep', only parts not already fontified are highlighted.
|
|
|
356 If `prepend' or `append', existing fontification is merged with the new, in
|
|
|
357 which the new or existing fontification, respectively, takes precedence.
|
|
|
358 If LAXMATCH is non-nil, no error is signalled if there is no MATCH in MATCHER.
|
|
|
359
|
|
|
360 For example, an element of the form highlights (if not already highlighted):
|
|
|
361
|
|
|
362 \"\\\\\\=<foo\\\\\\=>\" Discrete occurrences of \"foo\" in the value of the
|
|
|
363 variable `font-lock-keyword-face'.
|
|
|
364 (\"fu\\\\(bar\\\\)\" . 1) Substring \"bar\" within all occurrences of \"fubar\" in
|
|
|
365 the value of `font-lock-keyword-face'.
|
|
|
366 (\"fubar\" . fubar-face) Occurrences of \"fubar\" in the value of `fubar-face'.
|
|
|
367 (\"foo\\\\|bar\" 0 foo-bar-face t)
|
|
|
368 Occurrences of either \"foo\" or \"bar\" in the value
|
|
|
369 of `foo-bar-face', even if already highlighted.
|
|
|
370
|
|
|
371 MATCH-ANCHORED should be of the form:
|
|
|
372
|
|
|
373 (MATCHER PRE-MATCH-FORM POST-MATCH-FORM MATCH-HIGHLIGHT ...)
|
|
|
374
|
|
|
375 Where MATCHER is as for MATCH-HIGHLIGHT with one exception; see below.
|
|
|
376 PRE-MATCH-FORM and POST-MATCH-FORM are evaluated before the first, and after
|
|
|
377 the last, instance MATCH-ANCHORED's MATCHER is used. Therefore they can be
|
|
|
378 used to initialize before, and cleanup after, MATCHER is used. Typically,
|
|
|
379 PRE-MATCH-FORM is used to move to some position relative to the original
|
|
|
380 MATCHER, before starting with MATCH-ANCHORED's MATCHER. POST-MATCH-FORM might
|
|
|
381 be used to move, before resuming with MATCH-ANCHORED's parent's MATCHER.
|
|
|
382
|
|
|
383 For example, an element of the form highlights (if not already highlighted):
|
|
|
384
|
|
|
385 (\"\\\\\\=<anchor\\\\\\=>\" (0 anchor-face) (\"\\\\\\=<item\\\\\\=>\" nil nil (0 item-face)))
|
|
|
386
|
|
|
387 Discrete occurrences of \"anchor\" in the value of `anchor-face', and subsequent
|
|
|
388 discrete occurrences of \"item\" (on the same line) in the value of `item-face'.
|
|
|
389 (Here PRE-MATCH-FORM and POST-MATCH-FORM are nil. Therefore \"item\" is
|
|
|
390 initially searched for starting from the end of the match of \"anchor\", and
|
|
|
391 searching for subsequent instance of \"anchor\" resumes from where searching
|
|
|
392 for \"item\" concluded.)
|
|
|
393
|
|
|
394 The above-mentioned exception is as follows. The limit of the MATCHER search
|
|
|
395 defaults to the end of the line after PRE-MATCH-FORM is evaluated.
|
|
|
396 However, if PRE-MATCH-FORM returns a position greater than the position after
|
|
|
397 PRE-MATCH-FORM is evaluated, that position is used as the limit of the search.
|
|
|
398 It is generally a bad idea to return a position greater than the end of the
|
|
|
399 line, i.e., cause the MATCHER search to span lines.
|
|
|
400
|
|
|
401 Note that the MATCH-ANCHORED feature is experimental; in the future, we may
|
|
|
402 replace it with other ways of providing this functionality.
|
|
|
403
|
|
|
404 These regular expressions should not match text which spans lines. While
|
|
|
405 \\[font-lock-fontify-buffer] handles multi-line patterns correctly, updating
|
|
|
406 when you edit the buffer does not, since it considers text one line at a time.
|
|
|
407
|
|
|
408 Be very careful composing regexps for this list;
|
|
|
409 the wrong pattern can dramatically slow things down!")

423 KEYWORDS may be a symbol (a variable or function whose value is the keywords

424 to use for fontification) or a list of symbols. If KEYWORDS-ONLY is non-nil,
|
|

425 syntactic fontification (strings and comments) is not performed. If CASE-FOLD

434 be outside a syntactic block), or `beginning-of-defun' for programming modes or
