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. |
178c5d9c | 30 | |
82641697 GM |
31 | 2. Relative proportionate width, aka character set width or set |
32 | width (swidth), e.g. `semi-compressed'. | |
178c5d9c | 33 | |
39506348 | 34 | 3. Font height in 1/10pt. |
178c5d9c | 35 | |
82641697 | 36 | 4. Font weight, e.g. `bold'. |
178c5d9c | 37 | |
82641697 | 38 | 5. Font slant, e.g. `italic'. |
178c5d9c | 39 | |
82641697 | 40 | 6. Foreground color. |
178c5d9c | 41 | |
82641697 GM |
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 | ||
2c20458f MB |
68 | 15. A face name or list of face names from which to inherit attributes. |
69 | ||
82641697 GM |
70 | Faces are frame-local by nature because Emacs allows to define the |
71 | same named face (face names are symbols) differently for different | |
72 | frames. Each frame has an alist of face definitions for all named | |
73 | faces. The value of a named face in such an alist is a Lisp vector | |
39506348 KH |
74 | with the symbol `face' in slot 0, and a slot for each of the face |
75 | attributes mentioned above. | |
82641697 GM |
76 | |
77 | There is also a global face alist `Vface_new_frame_defaults'. Face | |
78 | definitions from this list are used to initialize faces of newly | |
79 | created frames. | |
178c5d9c | 80 | |
82641697 | 81 | A face doesn't have to specify all attributes. Those not specified |
39506348 KH |
82 | have a value of `unspecified'. Faces specifying all attributes but |
83 | the 14th are called `fully-specified'. | |
82641697 GM |
84 | |
85 | ||
86 | Face merging. | |
87 | ||
88 | The display style of a given character in the text is determined by | |
89 | combining several faces. This process is called `face merging'. | |
90 | Any aspect of the display style that isn't specified by overlays or | |
91 | text properties is taken from the `default' face. Since it is made | |
92 | sure that the default face is always fully-specified, face merging | |
93 | always results in a fully-specified face. | |
94 | ||
95 | ||
96 | Face realization. | |
178c5d9c | 97 | |
82641697 GM |
98 | After all face attributes for a character have been determined by |
99 | merging faces of that character, that face is `realized'. The | |
100 | realization process maps face attributes to what is physically | |
101 | available on the system where Emacs runs. The result is a | |
102 | `realized face' in form of a struct face which is stored in the | |
103 | face cache of the frame on which it was realized. | |
104 | ||
39506348 KH |
105 | Face realization is done in the context of the character to display |
106 | because different fonts may be used for different characters. In | |
107 | other words, for characters that have different font | |
108 | specifications, different realized faces are needed to display | |
82641697 GM |
109 | them. |
110 | ||
39506348 KH |
111 | Font specification is done by fontsets. See the comment in |
112 | fontset.c for the details. In the current implementation, all ASCII | |
113 | characters share the same font in a fontset. | |
114 | ||
115 | Faces are at first realized for ASCII characters, and, at that | |
116 | time, assigned a specific realized fontset. Hereafter, we call | |
117 | such a face as `ASCII face'. When a face for a multibyte character | |
118 | is realized, it inherits (thus shares) a fontset of an ASCII face | |
119 | that has the same attributes other than font-related ones. | |
120 | ||
121 | Thus, all realzied face have a realized fontset. | |
82641697 GM |
122 | |
123 | ||
124 | Unibyte text. | |
125 | ||
39506348 KH |
126 | Unibyte text (i.e. raw 8-bit characters) is displayed with the same |
127 | font as ASCII characters. That is because it is expected that | |
128 | unibyte text users specify a font that is suitable both for ASCII | |
129 | and raw 8-bit characters. | |
130 | ||
82641697 GM |
131 | |
132 | Font selection. | |
133 | ||
134 | Font selection tries to find the best available matching font for a | |
39506348 | 135 | given (character, face) combination. |
82641697 | 136 | |
39506348 KH |
137 | If the face specifies a fontset name, that fontset determines a |
138 | pattern for fonts of the given character. If the face specifies a | |
139 | font name or the other font-related attributes, a fontset is | |
140 | realized from the default fontset. In that case, that | |
141 | specification determines a pattern for ASCII characters and the | |
142 | default fontset determines a pattern for multibyte characters. | |
82641697 GM |
143 | |
144 | Available fonts on the system on which Emacs runs are then matched | |
145 | against the font pattern. The result of font selection is the best | |
146 | match for the given face attributes in this font list. | |
147 | ||
148 | Font selection can be influenced by the user. | |
149 | ||
150 | 1. The user can specify the relative importance he gives the face | |
151 | attributes width, height, weight, and slant by setting | |
152 | face-font-selection-order (faces.el) to a list of face attribute | |
153 | names. The default is '(:width :height :weight :slant), and means | |
154 | that font selection first tries to find a good match for the font | |
155 | width specified by a face, then---within fonts with that | |
156 | width---tries to find a best match for the specified font height, | |
157 | etc. | |
158 | ||
159 | 2. Setting face-alternative-font-family-alist allows the user to | |
160 | specify alternative font families to try if a family specified by a | |
161 | face doesn't exist. | |
162 | ||
163 | ||
178c5d9c | 164 | Character compositition. |
39506348 KH |
165 | |
166 | Usually, the realization process is already finished when Emacs | |
167 | actually reflects the desired glyph matrix on the screen. However, | |
168 | on displaying a composition (sequence of characters to be composed | |
169 | on the screen), a suitable font for the components of the | |
170 | composition is selected and realized while drawing them on the | |
171 | screen, i.e. the realization process is delayed but in principle | |
172 | the same. | |
82641697 | 173 | |
178c5d9c | 174 | |
82641697 GM |
175 | Initialization of basic faces. |
176 | ||
177 | The faces `default', `modeline' are considered `basic faces'. | |
178 | When redisplay happens the first time for a newly created frame, | |
179 | basic faces are realized for CHARSET_ASCII. Frame parameters are | |
180 | used to fill in unspecified attributes of the default face. */ | |
