22 | /* Faces. | |
23 | ||
24 | When using Emacs with X, the display style of characters can be | |
25 | changed by defining `faces'. Each face can specify the following | |
26 | display attributes: | |
27 | ||
39506348 | 28 | 1. Font family name. |
178c5d9c | 29 | |
53aaf1e2 KH |
30 | 2. Font foundary name. |
31 | ||
32 | 3. Relative proportionate width, aka character set width or set | |
82641697 | 33 | width (swidth), e.g. `semi-compressed'. |
178c5d9c | 34 | |
53aaf1e2 | 35 | 4. Font height in 1/10pt. |
178c5d9c | 36 | |
53aaf1e2 | 37 | 5. Font weight, e.g. `bold'. |
178c5d9c | 38 | |
53aaf1e2 | 39 | 6. Font slant, e.g. `italic'. |
178c5d9c | 40 | |
53aaf1e2 | 41 | 7. Foreground color. |
178c5d9c | 42 | |
53aaf1e2 | 43 | 8. Background color. |
82641697 | 44 | |
53aaf1e2 | 45 | 9. Whether or not characters should be underlined, and in what color. |
82641697 | 46 | |
53aaf1e2 | 47 | 10. Whether or not characters should be displayed in inverse video. |
82641697 | 48 | |
53aaf1e2 | 49 | 11. A background stipple, a bitmap. |
82641697 | 50 | |
53aaf1e2 | 51 | 12. Whether or not characters should be overlined, and in what color. |
82641697 | 52 | |
53aaf1e2 | 53 | 13. Whether or not characters should be strike-through, and in what |
82641697 GM |
54 | color. |
55 | ||
53aaf1e2 | 56 | 14. Whether or not a box should be drawn around characters, the box |
82641697 GM |
57 | type, and, for simple boxes, in what color. |
58 | ||
53aaf1e2 | 59 | 15. Font-spec, or nil. This is a special attribute. |
2dee4c0b KH |
60 | |
61 | A font-spec is a collection of font attributes (specs). | |
62 | ||
63 | When this attribute is specified, the face uses a font matching | |
64 | with the specs as is except for what overwritten by the specs in | |
65 | the fontset (see below). In addition, the other font-related | |
66 | attributes (1st thru 5th) are updated from the spec. | |
67 | ||
39506348 | 68 | On the other hand, if one of the other font-related attributes are |
2dee4c0b | 69 | specified, the correspoinding specs in this attribute is set to nil. |
39506348 | 70 | |
2c20458f MB |
71 | 15. A face name or list of face names from which to inherit attributes. |
72 | ||
a08332c0 GM |
73 | 16. A specified average font width, which is invisible from Lisp, |
74 | and is used to ensure that a font specified on the command line, | |
75 | for example, can be matched exactly. | |
76 | ||
2dee4c0b KH |
77 | 17. A fontset name. This is another special attribute. |
78 | ||
79 | A fontset is a mappings from characters to font-specs, and the | |
80 | specs overwrite the font-spec in the 14th attribute. | |

83 | Faces are frame-local by nature because Emacs allows to define the |
84 | same named face (face names are symbols) differently for different | |
85 | frames. Each frame has an alist of face definitions for all named | |
86 | faces. The value of a named face in such an alist is a Lisp vector | |
39506348 KH |
87 | with the symbol `face' in slot 0, and a slot for each of the face |
88 | attributes mentioned above. | |
82641697 GM |
89 | |
90 | There is also a global face alist `Vface_new_frame_defaults'. Face | |
91 | definitions from this list are used to initialize faces of newly | |
92 | created frames. | |
178c5d9c | 93 | |
82641697 | 94 | A face doesn't have to specify all attributes. Those not specified |
39506348 KH |
95 | have a value of `unspecified'. Faces specifying all attributes but |
96 | the 14th are called `fully-specified'. | |
82641697 GM |
97 | |
98 | ||
99 | Face merging. | |
100 | ||
101 | The display style of a given character in the text is determined by | |
102 | combining several faces. This process is called `face merging'. | |
103 | Any aspect of the display style that isn't specified by overlays or | |
104 | text properties is taken from the `default' face. Since it is made | |
105 | sure that the default face is always fully-specified, face merging | |
106 | always results in a fully-specified face. | |
107 | ||
108 | ||
109 | Face realization. | |
178c5d9c | 110 | |
82641697 GM |
111 | After all face attributes for a character have been determined by |
112 | merging faces of that character, that face is `realized'. The | |
113 | realization process maps face attributes to what is physically | |
114 | available on the system where Emacs runs. The result is a | |
115 | `realized face' in form of a struct face which is stored in the | |
116 | face cache of the frame on which it was realized. | |
117 | ||
39506348 KH |
118 | Face realization is done in the context of the character to display |
119 | because different fonts may be used for different characters. In | |
120 | other words, for characters that have different font | |
121 | specifications, different realized faces are needed to display | |
82641697 GM |
122 | them. |
123 | ||
39506348 KH |
124 | Font specification is done by fontsets. See the comment in |
125 | fontset.c for the details. In the current implementation, all ASCII | |
126 | characters share the same font in a fontset. | |
127 | ||
128 | Faces are at first realized for ASCII characters, and, at that | |
129 | time, assigned a specific realized fontset. Hereafter, we call | |
130 | such a face as `ASCII face'. When a face for a multibyte character | |
131 | is realized, it inherits (thus shares) a fontset of an ASCII face | |
132 | that has the same attributes other than font-related ones. | |
133 | ||
763bc839 | 134 | Thus, all realized faces have a realized fontset. |
82641697 GM |
135 | |
136 | ||
137 | Unibyte text. | |
138 | ||
39506348 KH |
139 | Unibyte text (i.e. raw 8-bit characters) is displayed with the same |
140 | font as ASCII characters. That is because it is expected that | |
141 | unibyte text users specify a font that is suitable both for ASCII | |
142 | and raw 8-bit characters. | |
143 | ||
82641697 GM |
144 | |
145 | Font selection. | |
146 | ||
147 | Font selection tries to find the best available matching font for a | |
39506348 | 148 | given (character, face) combination. |
82641697 | 149 | |
39506348 KH |
150 | If the face specifies a fontset name, that fontset determines a |
151 | pattern for fonts of the given character. If the face specifies a | |
152 | font name or the other font-related attributes, a fontset is | |
153 | realized from the default fontset. In that case, that | |
154 | specification determines a pattern for ASCII characters and the | |
155 | default fontset determines a pattern for multibyte characters. | |
82641697 GM |
156 | |
157 | Available fonts on the system on which Emacs runs are then matched | |
158 | against the font pattern. The result of font selection is the best | |
159 | match for the given face attributes in this font list. | |
160 | ||
161 | Font selection can be influenced by the user. | |
162 | ||
163 | 1. The user can specify the relative importance he gives the face | |
164 | attributes width, height, weight, and slant by setting | |
165 | face-font-selection-order (faces.el) to a list of face attribute | |
166 | names. The default is '(:width :height :weight :slant), and means | |
167 | that font selection first tries to find a good match for the font | |
168 | width specified by a face, then---within fonts with that | |
169 | width---tries to find a best match for the specified font height, | |
170 | etc. | |
171 | ||
c824bfbc | 172 | 2. Setting face-font-family-alternatives allows the user to |
82641697 GM |
173 | specify alternative font families to try if a family specified by a |
174 | face doesn't exist. | |
175 | ||
c824bfbc KH |
176 | 3. Setting face-font-registry-alternatives allows the user to |
177 | specify all alternative font registries to try for a face | |
178 | specifying a registry. | |
179 | ||
180 | 4. Setting face-ignored-fonts allows the user to ignore specific | |
181 | fonts. | |
182 | ||
82641697 | 183 | |
ec7a10e3 | 184 | Character composition. |
39506348 KH |
185 | |
186 | Usually, the realization process is already finished when Emacs | |
187 | actually reflects the desired glyph matrix on the screen. However, | |
188 | on displaying a composition (sequence of characters to be composed | |
189 | on the screen), a suitable font for the components of the | |
190 | composition is selected and realized while drawing them on the | |
191 | screen, i.e. the realization process is delayed but in principle | |
192 | the same. | |
82641697 | 193 | |

82641697 GM |
195 | Initialization of basic faces. |
196 | ||
197 | The faces `default', `modeline' are considered `basic faces'. | |
198 | When redisplay happens the first time for a newly created frame, | |
199 | basic faces are realized for CHARSET_ASCII. Frame parameters are | |
200 | used to fill in unspecified attributes of the default face. */ | |

6755 | Each element is of the form: | |
6756 | ||
6757 | (FACE REPLACEMENT...), | |
6758 | ||
6759 | which causes display of the face FACE to use REPLACEMENT... instead. | |
635c0aa1 CY |
6760 | REPLACEMENT... is interpreted the same way as the value of a `face' |
6761 | text property: it may be (1) A face name, (2) A list of face names, | |
6762 | (3) A property-list of face attribute/value pairs, or (4) A list of | |
6763 | face names or lists containing face attribute/value pairs. | |
f2cec7a9 MB |
6764 | |
6765 | Multiple entries in REPLACEMENT... are merged together to form the final | |
6766 | result, with faces or attributes earlier in the list taking precedence | |
6767 | over those that are later. | |
6768 | ||
6769 | Face-name remapping cycles are suppressed; recursive references use the | |
6770 | underlying face instead of the remapped face. So a remapping of the form: | |
6771 | ||
6772 | (FACE EXTRA-FACE... FACE) | |
6773 | ||
6774 | or: | |
6775 | ||
6776 | (FACE (FACE-ATTR VAL ...) FACE) | |
6777 | ||
6778 | will cause EXTRA-FACE... or (FACE-ATTR VAL ...) to be _merged_ with the | |
6779 | existing definition of FACE. Note that for the default face, this isn't | |
6780 | necessary, as every face inherits from the default face. | |
6781 | ||
6782 | Making this variable buffer-local is a good way to allow buffer-specific | |
6783 | face definitions. For instance, the mode my-mode could define a face | |
6784 | `my-mode-default', and then in the mode setup function, do: | |
6785 | ||
6786 | (set (make-local-variable 'face-remapping-alist) | |
635c0aa1 CY |
6787 | '((default my-mode-default)))). |
6788 | ||
6789 | Because Emacs normally only redraws screen areas when the underlying | |
6790 | buffer contents change, you may need to call `redraw-display' after | |
6791 | changing this variable for it to take effect. */); | |
