57 | ||
58 | A fontset is a collection of font related information to give | |
1d5d7200 KH |
59 | similar appearance (style, etc) of characters. A fontset has two |
60 | roles. One is to use for the frame parameter `font' as if it is an | |
61 | ASCII font. In that case, Emacs uses the font specified for | |
62 | `ascii' script for the frame's default font. | |
63 | ||
64 | Another role, the more important one, is to provide information | |
65 | about which font to use for each non-ASCII character. | |
66 | ||
67 | There are two kinds of fontsets; base and realized. A base fontset | |
68 | is created by `new-fontset' from Emacs Lisp explicitly. A realized | |
69 | fontset is created implicitly when a face is realized for ASCII | |
70 | characters. A face is also realized for non-ASCII characters based | |
71 | on an ASCII face. All of non-ASCII faces based on the same ASCII | |
72 | face share the same realized fontset. | |
8f924df7 | 73 | |
06f76f0d KH |
74 | A fontset object is implemented by a char-table whose default value |
75 | and parent are always nil. | |
fc8865fc | 76 | |
1d5d7200 KH |
77 | An element of a base fontset is a vector of FONT-DEFs which itself |
78 | is a vector [ FONT-SPEC ENCODING REPERTORY ]. | |
79 | ||
80 | FONT-SPEC is: | |
81 | [ FAMILY WEIGHT SLANT SWIDTH ADSTYLE REGISTRY ] | |
06f76f0d | 82 | or |
1d5d7200 KH |
83 | FONT-NAME |
84 | where FAMILY, WEIGHT, SLANT, SWIDTH, ADSTYLE, REGISTRY, and | |
85 | FONT-NAME are strings. | |
86 | ||
87 | ENCODING is a charset ID or a char-table that can convert | |
88 | characters to glyph codes of the corresponding font. | |
89 | ||
90 | REPERTORY is a charset ID or nil. If REPERTORY is a charset ID, | |
91 | the repertory of the charset exactly matches with that of the font. | |
92 | If REPERTORY is nil, we consult with the font itself to get the | |
93 | repertory. | |
94 | ||
95 | ENCODING and REPERTORY are extracted from the variable | |
96 | Vfont_encoding_alist by using a font name generated form FONT-SPEC | |
97 | (if it is a vector) or FONT-NAME as a key. | |
98 | ||
99 | ||
100 | An element of a realized fontset is nil or t, or has this form: | |
fc8865fc | 101 | |
1d5d7200 | 102 | ( CHARSET-PRIORITY-LIST-TICK . FONT-VECTOR ) |
0d407d77 | 103 | |
1d5d7200 | 104 | FONT-VECTOR is a vector whose elements have this form: |
0d407d77 | 105 | |
1d5d7200 | 106 | [ FACE-ID FONT-INDEX FONT-DEF ] |
0d407d77 | 107 | |
1d5d7200 KH |
108 | FONT-VECTOR is automatically reordered by the current charset |
109 | priority list. | |
0d407d77 | 110 | |
1d5d7200 KH |
111 | The value nil means that we have not yet generated FONT-VECTOR from |
112 | the base of the fontset. | |
0d407d77 | 113 | |
1d5d7200 KH |
114 | The value t means that no font is available for the corresponding |
115 | range of characters. | |
0d407d77 | 116 | |
0d407d77 | 117 | |
d6aaac9e | 118 | A fontset has 8 extra slots. |
0d407d77 | 119 | |
1d5d7200 | 120 | The 1st slot: the ID number of the fontset |
0d407d77 | 121 | |
1d5d7200 KH |
122 | The 2nd slot: |
123 | base: the name of the fontset | |
124 | realized: nil | |
0d407d77 | 125 | |
1d5d7200 | 126 | The 3rd slot: |
d6aaac9e | 127 | base: nil |
1d5d7200 | 128 | realized: the base fontset |
06f76f0d | 129 | |
1d5d7200 KH |
130 | The 4th slot: |
131 | base: nil | |
132 | realized: the frame that the fontset belongs to | |
0d407d77 | 133 | |
1d5d7200 KH |
134 | The 5th slot: |
135 | base: the font name for ASCII characters | |
136 | realized: nil | |
0d407d77 | 137 | |
1d5d7200 KH |
138 | The 6th slot: |
139 | base: nil | |
140 | realized: the ID number of a face to use for characters that | |
141 | has no font in a realized fontset. | |
0d407d77 | 142 | |
1d5d7200 KH |
143 | The 7th slot: |
144 | base: nil | |
145 | realized: Alist of font index vs the corresponding repertory | |
146 | char-table. | |
147 | ||
d6aaac9e KH |
148 | The 8th slot: |
149 | base: nil | |
150 | realized: If the base is not the default fontset, a fontset | |
151 | realized from the default fontset, else nil. | |
1d5d7200 KH |
152 | |
153 | All fontsets are recorded in the vector Vfontset_table. | |
0d407d77 KH |
154 | |
155 | ||
156 | DEFAULT FONTSET | |
157 | ||
1d5d7200 KH |
158 | There's a special base fontset named `default fontset' which |
159 | defines the default font specifications. When a base fontset | |
160 | doesn't specify a font for a specific character, the corresponding | |
161 | value in the default fontset is used. | |
0d407d77 | 162 | |
afe93d01 KH |
163 | The parent of a realized fontset created for such a face that has |
164 | no fontset is the default fontset. | |
0d407d77 KH |
165 | |
166 | ||
167 | These structures are hidden from the other codes than this file. | |
168 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d KH |
169 | usually use the variable name `fontset' for IDs. But, in this |
170 | file, we always use varialbe name `id' for IDs, and name `fontset' | |
1d5d7200 | 171 | for an actual fontset object, i.e., char-table. |
