27 ;;; Commentary:
29 ;; Some comments on the use of faces:
30 ;;
31 ;; o `c-label-face-name' is either `font-lock-constant-face' (in
32 ;; Emacs), or `font-lock-reference-face'.
33 ;;
34 ;; o `c-constant-face-name', `c-reference-face-name' and
35 ;; `c-doc-markup-face-name' are essentially set up like
36 ;; `c-label-face-name'.
37 ;;
38 ;; o `c-preprocessor-face-name' is `font-lock-preprocessor-face' in
39 ;; XEmacs and - in lack of a closer equivalent -
40 ;; `font-lock-builtin-face' or `font-lock-reference-face' in Emacs.
41 ;;
42 ;; o `c-doc-face-name' is `font-lock-doc-string-face' in XEmacs,
43 ;; `font-lock-doc-face' in Emacs 21 and later, or
44 ;; `font-lock-comment-face' in older Emacs (that since source
45 ;; documentation are actually comments in these languages, as opposed
46 ;; to elisp).
47 ;;
48 ;; TBD: We should probably provide real faces for the above uses and
49 ;; instead initialize them from the standard faces.
51 ;;; Code:
53 ;; The faces that already have been put onto the text is tested in
54 ;; various places to direct further fontifications. For this to work,
55 ;; the following assumptions regarding the faces must hold (apart from
56 ;; the dependencies on the font locking order):
57 ;;
58 ;; o `font-lock-comment-face' and the face in `c-doc-face-name' is
59 ;; not used in anything but comments.
60 ;; o If any face (e.g. `c-doc-markup-face-name') but those above is
61 ;; used in comments, it doesn't replace them.
62 ;; o `font-lock-string-face' is not used in anything but string
63 ;; literals (single or double quoted).
64 ;; o `font-lock-keyword-face' and the face in `c-label-face-name' are
65 ;; never overlaid with other faces.
