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

|
|
|
267 However, if an item or (typically) items is to be hightlighted following the
|
|

268 instance of another item (the anchor) then MATCH-ANCHORED may be required.

269
|

270 MATCH-HIGHLIGHT should be of the form:

271
|
|
|
272 (MATCH FACENAME OVERRIDE LAXMATCH)
|
|
|
273
|
|
|
274 Where MATCHER can be either the regexp to search for, or the function name to
|
|
|
275 call to make the search (called with one argument, the limit of the search).
|
|
|
276 MATCH is the subexpression of MATCHER to be highlighted. FACENAME is either
|
|
|
277 a symbol naming a face, or an expression whose value is the face name to use.
|
|
|
278 If you want FACENAME to be a symbol that evaluates to a face, use a form

|
|
283 If `prepend' or `append', existing fontification is merged with the new, in
|
|
|
284 which the new or existing fontification, respectively, takes precedence.
|
|
|
285 If LAXMATCH is non-nil, no error is signalled if there is no MATCH in MATCHER.
|
|

286
|
|

287 For example, an element of the form highlights (if not already highlighted):

289 \"\\\\\\=<foo\\\\\\=>\" Discrete occurrences of \"foo\" in the value of the
|
|
|
290 variable `font-lock-keyword-face'.
|
|
|
291 (\"fu\\\\(bar\\\\)\" . 1) Substring \"bar\" within all occurrences of \"fubar\" in
|
|
|
292 the value of `font-lock-keyword-face'.
|
|
|
293 (\"fubar\" . fubar-face) Occurrences of \"fubar\" in the value of `fubar-face'.
|
|
|
294 (\"foo\\\\|bar\" 0 foo-bar-face t)
|
|
|
295 Occurrences of either \"foo\" or \"bar\" in the value
|
|
|
296 of `foo-bar-face', even if already highlighted.
|
|
|
297
|
|
|
298 MATCH-ANCHORED should be of the form:
|
|
|
299
|
|
|
300 (MATCHER PRE-MATCH-FORM POST-MATCH-FORM MATCH-HIGHLIGHT ...)
|
|
|
301
|
|
|
302 Where MATCHER is as for MATCH-HIGHLIGHT with one exception. The limit of the
|
|
|
303 search is currently guaranteed to be (no greater than) the end of the line.
|
|
|
304 PRE-MATCH-FORM and POST-MATCH-FORM are evaluated before the first, and after
|
|
|
305 the last, instance MATCH-ANCHORED's MATCHER is used. Therefore they can be
|
|
|
306 used to initialise before, and cleanup after, MATCHER is used. Typically,
|
|

307 PRE-MATCH-FORM is used to move to some position relative to the original

308 MATCHER, before starting with MATCH-ANCHORED's MATCHER. POST-MATCH-FORM might

309 be used to move, before resuming with MATCH-ANCHORED's parent's MATCHER.
|

311 For example, an element of the form highlights (if not already highlighted):
|
|
|
312
|
|
|
313 (\"\\\\\\=<anchor\\\\\\=>\" (0 anchor-face) (\"\\\\\\=<item\\\\\\=>\" nil nil (0 item-face)))
|
|
|
314
|
|
|
315 Discrete occurrences of \"anchor\" in the value of `anchor-face', and subsequent
|
|
|
316 discrete occurrences of \"item\" (on the same line) in the value of `item-face'.
|
|
|
317 (Here PRE-MATCH-FORM and POST-MATCH-FORM are nil. Therefore \"item\" is
|
|
|
318 initially searched for starting from the end of the match of \"anchor\", and
|
|
|
319 searching for subsequent instance of \"anchor\" resumes from where searching
|
|
|
320 for \"item\" concluded.)
|
|
|
321
|
|
|
322 Note that the MATCH-ANCHORED feature is experimental; in the future, we may
|
|
|
323 replace it with other ways of providing this functionality.

325 These regular expressions should not match text which spans lines. While
|

326 \\[font-lock-fontify-buffer] handles multi-line patterns correctly, updating
|
|
|
327 when you edit the buffer does not, since it considers text one line at a time.

328
|
|
|
329 Be very careful composing regexps for this list;

330 the wrong pattern can dramatically slow things down!")
