58 | ||
59 | A fontset is a collection of font related information to give | |
60 | similar appearance (style, size, etc) of characters. There are two | |
61 | kinds of fontsets; base and realized. A base fontset is created by | |
62 | new-fontset from Emacs Lisp explicitly. A realized fontset is | |
63 | created implicitly when a face is realized for ASCII characters. A | |
64 | face is also realized for multibyte characters based on an ASCII | |
65 | face. All of the multibyte faces based on the same ASCII face | |
66 | share the same realized fontset. | |
fc8865fc | 67 | |
0d407d77 KH |
68 | A fontset object is implemented by a char-table. |
69 | ||
70 | An element of a base fontset is: | |
71 | (INDEX . FONTNAME) or | |
72 | (INDEX . (FOUNDRY . REGISTRY )) | |
73 | FONTNAME is a font name pattern for the corresponding character. | |
fc8865fc | 74 | FOUNDRY and REGISTRY are respectively foundry and registry fields of |
0d407d77 KH |
75 | a font name for the corresponding character. INDEX specifies for |
76 | which character (or generic character) the element is defined. It | |
77 | may be different from an index to access this element. For | |
78 | instance, if a fontset defines some font for all characters of | |
79 | charset `japanese-jisx0208', INDEX is the generic character of this | |
80 | charset. REGISTRY is the | |
81 | ||
82 | An element of a realized fontset is FACE-ID which is a face to use | |
fc8865fc | 83 | for displaying the corresponding character. |
0d407d77 | 84 | |
fc8865fc | 85 | All single byte characters (ASCII and 8bit-unibyte) share the same |
11d9bd93 KH |
86 | element in a fontset. The element is stored in the first element |
87 | of the fontset. | |
0d407d77 KH |
88 | |
89 | To access or set each element, use macros FONTSET_REF and | |
90 | FONTSET_SET respectively for efficiency. | |
91 | ||
92 | A fontset has 3 extra slots. | |
93 | ||
94 | The 1st slot is an ID number of the fontset. | |
95 | ||
96 | The 2nd slot is a name of the fontset. This is nil for a realized | |
97 | face. | |
98 | ||
99 | The 3rd slot is a frame that the fontset belongs to. This is nil | |
100 | for a default face. | |
101 | ||
102 | A parent of a base fontset is nil. A parent of a realized fontset | |
103 | is a base fontset. | |
104 | ||
afe93d01 | 105 | All fontsets are recorded in Vfontset_table. |
0d407d77 KH |
106 | |
107 | ||
108 | DEFAULT FONTSET | |
109 | ||
110 | There's a special fontset named `default fontset' which defines a | |
afe93d01 KH |
111 | default fontname pattern. When a base fontset doesn't specify a |
112 | font for a specific character, the corresponding value in the | |
113 | default fontset is used. The format is the same as a base fontset. | |
0d407d77 | 114 | |
afe93d01 KH |
115 | The parent of a realized fontset created for such a face that has |
116 | no fontset is the default fontset. | |
0d407d77 KH |
117 | |
118 | ||
119 | These structures are hidden from the other codes than this file. | |
120 | The other codes handle fontsets only by their ID numbers. They | |
121 | usually use variable name `fontset' for IDs. But, in this file, we | |
fc8865fc | 122 | always use variable name `id' for IDs, and name `fontset' for the |
0d407d77 KH |
123 | actual fontset objects. |
