49 | ||
50 | A fontset is a collection of font related information to give | |
51 | similar appearance (style, size, etc) of characters. There are two | |
52 | kinds of fontsets; base and realized. A base fontset is created by | |
53 | new-fontset from Emacs Lisp explicitly. A realized fontset is | |
54 | created implicitly when a face is realized for ASCII characters. A | |
55 | face is also realized for multibyte characters based on an ASCII | |
56 | face. All of the multibyte faces based on the same ASCII face | |
57 | share the same realized fontset. | |
fc8865fc | 58 | |
0d407d77 KH |
59 | A fontset object is implemented by a char-table. |
60 | ||
61 | An element of a base fontset is: | |
62 | (INDEX . FONTNAME) or | |
63 | (INDEX . (FOUNDRY . REGISTRY )) | |
64 | FONTNAME is a font name pattern for the corresponding character. | |
fc8865fc | 65 | FOUNDRY and REGISTRY are respectively foundry and registry fields of |
0d407d77 KH |
66 | a font name for the corresponding character. INDEX specifies for |
67 | which character (or generic character) the element is defined. It | |
68 | may be different from an index to access this element. For | |
69 | instance, if a fontset defines some font for all characters of | |
70 | charset `japanese-jisx0208', INDEX is the generic character of this | |
71 | charset. REGISTRY is the | |
72 | ||
73 | An element of a realized fontset is FACE-ID which is a face to use | |
fc8865fc | 74 | for displaying the corresponding character. |
0d407d77 | 75 | |
fc8865fc | 76 | All single byte characters (ASCII and 8bit-unibyte) share the same |
11d9bd93 KH |
77 | element in a fontset. The element is stored in the first element |
78 | of the fontset. | |
0d407d77 KH |
79 | |
80 | To access or set each element, use macros FONTSET_REF and | |
81 | FONTSET_SET respectively for efficiency. | |
82 | ||
83 | A fontset has 3 extra slots. | |
84 | ||
85 | The 1st slot is an ID number of the fontset. | |
86 | ||
87 | The 2nd slot is a name of the fontset. This is nil for a realized | |
88 | face. | |
89 | ||
90 | The 3rd slot is a frame that the fontset belongs to. This is nil | |
91 | for a default face. | |
92 | ||
93 | A parent of a base fontset is nil. A parent of a realized fontset | |
94 | is a base fontset. | |
95 | ||
afe93d01 | 96 | All fontsets are recorded in Vfontset_table. |
0d407d77 KH |
97 | |
98 | ||
99 | DEFAULT FONTSET | |
100 | ||
101 | There's a special fontset named `default fontset' which defines a | |
afe93d01 KH |
102 | default fontname pattern. When a base fontset doesn't specify a |
103 | font for a specific character, the corresponding value in the | |
104 | default fontset is used. The format is the same as a base fontset. | |
0d407d77 | 105 | |
afe93d01 KH |
106 | The parent of a realized fontset created for such a face that has |
107 | no fontset is the default fontset. | |
0d407d77 KH |
108 | |
109 | ||
110 | These structures are hidden from the other codes than this file. | |
111 | The other codes handle fontsets only by their ID numbers. They | |
112 | usually use variable name `fontset' for IDs. But, in this file, we | |
fc8865fc | 113 | always use variable name `id' for IDs, and name `fontset' for the |
0d407d77 KH |
114 | actual fontset objects. |
