21 | /* New face implementation by Gerd Moellmann <gerd@gnu.org>. */ |
22 | ||
23 | /* Faces. | |
24 | ||
25 | When using Emacs with X, the display style of characters can be | |
26 | changed by defining `faces'. Each face can specify the following | |
27 | display attributes: | |
28 | ||
29 | 1. Font family or fontset alias name. | |
30 | ||
31 | 2. Relative proportionate width, aka character set width or set | |
32 | width (swidth), e.g. `semi-compressed'. | |
33 | ||
34 | 3. Font height in 1/10pt | |
35 | ||
36 | 4. Font weight, e.g. `bold'. | |
37 | ||
38 | 5. Font slant, e.g. `italic'. | |
39 | ||
40 | 6. Foreground color. | |
41 | ||
42 | 7. Background color. | |
43 | ||
44 | 8. Whether or not characters should be underlined, and in what color. | |
45 | ||
46 | 9. Whether or not characters should be displayed in inverse video. | |
47 | ||
48 | 10. A background stipple, a bitmap. | |
49 | ||
50 | 11. Whether or not characters should be overlined, and in what color. | |
51 | ||
52 | 12. Whether or not characters should be strike-through, and in what | |
53 | color. | |
54 | ||
55 | 13. Whether or not a box should be drawn around characters, the box | |
56 | type, and, for simple boxes, in what color. | |
57 | ||
58 | Faces are frame-local by nature because Emacs allows to define the | |
59 | same named face (face names are symbols) differently for different | |
60 | frames. Each frame has an alist of face definitions for all named | |
61 | faces. The value of a named face in such an alist is a Lisp vector | |
62 | with the symbol `face' in slot 0, and a slot for each each of the | |
63 | face attributes mentioned above. | |
64 | ||
65 | There is also a global face alist `Vface_new_frame_defaults'. Face | |
66 | definitions from this list are used to initialize faces of newly | |
67 | created frames. | |
68 | ||
69 | A face doesn't have to specify all attributes. Those not specified | |
70 | have a value of `unspecified'. Faces specifying all attributes are | |
71 | called `fully-specified'. | |
72 | ||
73 | ||
74 | Face merging. | |
75 | ||
76 | The display style of a given character in the text is determined by | |
77 | combining several faces. This process is called `face merging'. | |
78 | Any aspect of the display style that isn't specified by overlays or | |
79 | text properties is taken from the `default' face. Since it is made | |
80 | sure that the default face is always fully-specified, face merging | |
81 | always results in a fully-specified face. | |
82 | ||
83 | ||
84 | Face realization. | |
85 | ||
86 | After all face attributes for a character have been determined by | |
87 | merging faces of that character, that face is `realized'. The | |
88 | realization process maps face attributes to what is physically | |
89 | available on the system where Emacs runs. The result is a | |
90 | `realized face' in form of a struct face which is stored in the | |
91 | face cache of the frame on which it was realized. | |
92 | ||
93 | Face realization is done in the context of the charset of the | |
94 | character to display because different fonts and encodings are used | |
95 | for different charsets. In other words, for characters of | |
96 | different charsets, different realized faces are needed to display | |
97 | them. | |
98 | ||
99 | Faces are always realized for a specific character set and contain | |
100 | a specific font, even if the face being realized specifies a | |
101 | fontset (see `font selection' below). The reason is that the | |
102 | result of the new font selection stage is better than what can be | |
103 | done with statically defined font name patterns in fontsets. | |
104 | ||
105 | ||
106 | Unibyte text. | |
107 | ||
108 | In unibyte text, Emacs' charsets aren't applicable; function | |
109 | `char-charset' reports CHARSET_ASCII for all characters, including | |
110 | those > 0x7f. The X registry and encoding of fonts to use is | |
111 | determined from the variable `x-unibyte-registry-and-encoding' in | |
112 | this case. The variable is initialized at Emacs startup time from | |
113 | the font the user specified for Emacs. | |
114 | ||
115 | Currently all unibyte text, i.e. all buffers with | |
116 | enable_multibyte_characters nil are displayed with fonts of the | |
117 | same registry and encoding `x-unibyte-registry-and-encoding'. This | |
118 | is consistent with the fact that languages can also be set | |
119 | globally, only. | |
120 | ||
121 | ||
122 | Font selection. | |
123 | ||
124 | Font selection tries to find the best available matching font for a | |
125 | given (charset, face) combination. This is done slightly | |
126 | differently for faces specifying a fontset, or a font family name. | |
127 | ||
128 | If the face specifies a fontset alias name, that fontset determines | |
129 | a pattern for fonts of the given charset. If the face specifies a | |
130 | font family, a font pattern is constructed. Charset symbols have a | |
131 | property `x-charset-registry' for that purpose that maps a charset | |
132 | to an XLFD registry and encoding in the font pattern constructed. | |
133 | ||
134 | Available fonts on the system on which Emacs runs are then matched | |
135 | against the font pattern. The result of font selection is the best | |
136 | match for the given face attributes in this font list. | |
137 | ||
138 | Font selection can be influenced by the user. | |
139 | ||
140 | 1. The user can specify the relative importance he gives the face | |
141 | attributes width, height, weight, and slant by setting | |
142 | face-font-selection-order (faces.el) to a list of face attribute | |
143 | names. The default is '(:width :height :weight :slant), and means | |
144 | that font selection first tries to find a good match for the font | |
145 | width specified by a face, then---within fonts with that | |
146 | width---tries to find a best match for the specified font height, | |
147 | etc. | |
148 | ||
149 | 2. Setting face-alternative-font-family-alist allows the user to | |
150 | specify alternative font families to try if a family specified by a | |
151 | face doesn't exist. | |
152 | ||
153 | ||
154 | Composite characters. | |
155 | ||
156 | Realized faces for composite characters are the only ones having a | |
157 | fontset id >= 0. When a composite character is encoded into a | |
158 | sequence of non-composite characters (in xterm.c), a suitable font | |
159 | for the non-composite characters is then selected and realized, | |
160 | i.e. the realization process is delayed but in principle the same. | |
161 | ||
162 | ||
163 | Initialization of basic faces. | |
164 | ||
165 | The faces `default', `modeline' are considered `basic faces'. | |
166 | When redisplay happens the first time for a newly created frame, | |
167 | basic faces are realized for CHARSET_ASCII. Frame parameters are | |
168 | used to fill in unspecified attributes of the default face. */ | |
169 | ||

174 | servers. That's why I've put the code dealing with scalable fonts | |
175 | in #if's. */ | |
