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 | ||
39506348 | 29 | 1. Font family name. |
82641697 GM |
30 | |
31 | 2. Relative proportionate width, aka character set width or set | |
32 | width (swidth), e.g. `semi-compressed'. | |
33 | ||
39506348 | 34 | 3. Font height in 1/10pt. |
82641697 GM |
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 | ||
39506348 KH |
58 | 14. Font or fontset pattern, or nil. This is a special attribute. |
59 | When this attribyte is specified, the face uses a font opened by | |
60 | that pattern as is. In addition, all the other font-related | |
61 | attributes (1st thru 5th) are generated from the opened font name. | |
62 | On the other hand, if one of the other font-related attributes are | |
63 | specified, this attribute is set to nil. In that case, the face | |
64 | doesn't inherit this attribute from the `default' face, and uses a | |
65 | font determined by the other attributes (those may be inherited | |
66 | from the `default' face). | |
67 | ||
82641697 GM |
68 | Faces are frame-local by nature because Emacs allows to define the |
69 | same named face (face names are symbols) differently for different | |
70 | frames. Each frame has an alist of face definitions for all named | |
71 | faces. The value of a named face in such an alist is a Lisp vector | |
39506348 KH |
72 | with the symbol `face' in slot 0, and a slot for each of the face |
73 | attributes mentioned above. | |
82641697 GM |
74 | |
75 | There is also a global face alist `Vface_new_frame_defaults'. Face | |
76 | definitions from this list are used to initialize faces of newly | |
77 | created frames. | |
78 | ||
79 | A face doesn't have to specify all attributes. Those not specified | |
39506348 KH |
80 | have a value of `unspecified'. Faces specifying all attributes but |
81 | the 14th are called `fully-specified'. | |
82641697 GM |
82 | |
83 | ||
84 | Face merging. | |
85 | ||
86 | The display style of a given character in the text is determined by | |
87 | combining several faces. This process is called `face merging'. | |
88 | Any aspect of the display style that isn't specified by overlays or | |
89 | text properties is taken from the `default' face. Since it is made | |
90 | sure that the default face is always fully-specified, face merging | |
91 | always results in a fully-specified face. | |
92 | ||
93 | ||
94 | Face realization. | |
95 | ||
96 | After all face attributes for a character have been determined by | |
97 | merging faces of that character, that face is `realized'. The | |
98 | realization process maps face attributes to what is physically | |
99 | available on the system where Emacs runs. The result is a | |
100 | `realized face' in form of a struct face which is stored in the | |
101 | face cache of the frame on which it was realized. | |
102 | ||
39506348 KH |
103 | Face realization is done in the context of the character to display |
104 | because different fonts may be used for different characters. In | |
105 | other words, for characters that have different font | |
106 | specifications, different realized faces are needed to display | |
82641697 GM |
107 | them. |
108 | ||
39506348 KH |
109 | Font specification is done by fontsets. See the comment in |
110 | fontset.c for the details. In the current implementation, all ASCII | |
111 | characters share the same font in a fontset. | |
112 | ||
113 | Faces are at first realized for ASCII characters, and, at that | |
114 | time, assigned a specific realized fontset. Hereafter, we call | |
115 | such a face as `ASCII face'. When a face for a multibyte character | |
116 | is realized, it inherits (thus shares) a fontset of an ASCII face | |
117 | that has the same attributes other than font-related ones. | |
118 | ||
119 | Thus, all realzied face have a realized fontset. | |
82641697 GM |
120 | |
121 | ||
122 | Unibyte text. | |
123 | ||
39506348 KH |
124 | Unibyte text (i.e. raw 8-bit characters) is displayed with the same |
125 | font as ASCII characters. That is because it is expected that | |
126 | unibyte text users specify a font that is suitable both for ASCII | |
127 | and raw 8-bit characters. | |
128 | ||
82641697 GM |
129 | |
130 | Font selection. | |
131 | ||
132 | Font selection tries to find the best available matching font for a | |
39506348 | 133 | given (character, face) combination. |
82641697 | 134 | |
39506348 KH |
135 | If the face specifies a fontset name, that fontset determines a |
136 | pattern for fonts of the given character. If the face specifies a | |
137 | font name or the other font-related attributes, a fontset is | |
138 | realized from the default fontset. In that case, that | |
139 | specification determines a pattern for ASCII characters and the | |
140 | default fontset determines a pattern for multibyte characters. | |
82641697 GM |
141 | |
142 | Available fonts on the system on which Emacs runs are then matched | |
143 | against the font pattern. The result of font selection is the best | |
144 | match for the given face attributes in this font list. | |
145 | ||
146 | Font selection can be influenced by the user. | |
147 | ||
148 | 1. The user can specify the relative importance he gives the face | |
149 | attributes width, height, weight, and slant by setting | |
150 | face-font-selection-order (faces.el) to a list of face attribute | |
151 | names. The default is '(:width :height :weight :slant), and means | |
152 | that font selection first tries to find a good match for the font | |
153 | width specified by a face, then---within fonts with that | |
154 | width---tries to find a best match for the specified font height, | |
155 | etc. | |
156 | ||
157 | 2. Setting face-alternative-font-family-alist allows the user to | |
158 | specify alternative font families to try if a family specified by a | |
159 | face doesn't exist. | |
160 | ||
161 | ||
39506348 KH |
162 | Character compositition. |
163 | ||
164 | Usually, the realization process is already finished when Emacs | |
165 | actually reflects the desired glyph matrix on the screen. However, | |
166 | on displaying a composition (sequence of characters to be composed | |
167 | on the screen), a suitable font for the components of the | |
168 | composition is selected and realized while drawing them on the | |
169 | screen, i.e. the realization process is delayed but in principle | |
170 | the same. | |
82641697 GM |
171 | |
172 | ||
173 | Initialization of basic faces. | |
174 | ||
175 | The faces `default', `modeline' are considered `basic faces'. | |
176 | When redisplay happens the first time for a newly created frame, | |
177 | basic faces are realized for CHARSET_ASCII. Frame parameters are | |
178 | used to fill in unspecified attributes of the default face. */ | |
