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 | |
6bad8007 KH |
102 | [CHARSET-PRIORITY-LIST-TICK PREFERRED-CHARSET-ID PREFERRED-FONT-DEF |
103 | FONT-DEF0 FONT-DEF1 ...]. | |
0d407d77 | 104 | |
6bad8007 | 105 | FONT-DEFn has this form: |
0d407d77 | 106 | |
1d5d7200 | 107 | [ FACE-ID FONT-INDEX FONT-DEF ] |
0d407d77 | 108 | |
6bad8007 | 109 | FONT-DEFn is automatically reordered by the current charset |
1d5d7200 | 110 | priority list. |
0d407d77 | 111 | |
1d5d7200 KH |
112 | The value nil means that we have not yet generated FONT-VECTOR from |
113 | the base of the fontset. | |
0d407d77 | 114 | |
1d5d7200 KH |
115 | The value t means that no font is available for the corresponding |
116 | range of characters. | |
0d407d77 | 117 | |
0d407d77 | 118 | |
eb36588a | 119 | A fontset has 9 extra slots. |
0d407d77 | 120 | |
1d5d7200 | 121 | The 1st slot: the ID number of the fontset |
0d407d77 | 122 | |
1d5d7200 KH |
123 | The 2nd slot: |
124 | base: the name of the fontset | |
125 | realized: nil | |
0d407d77 | 126 | |
1d5d7200 | 127 | The 3rd slot: |
d6aaac9e | 128 | base: nil |
1d5d7200 | 129 | realized: the base fontset |
06f76f0d | 130 | |
1d5d7200 KH |
131 | The 4th slot: |
132 | base: nil | |
133 | realized: the frame that the fontset belongs to | |
0d407d77 | 134 | |
1d5d7200 KH |
135 | The 5th slot: |
136 | base: the font name for ASCII characters | |
137 | realized: nil | |
0d407d77 | 138 | |
1d5d7200 KH |
139 | The 6th slot: |
140 | base: nil | |
141 | realized: the ID number of a face to use for characters that | |
142 | has no font in a realized fontset. | |
0d407d77 | 143 | |
1d5d7200 KH |
144 | The 7th slot: |
145 | base: nil | |
146 | realized: Alist of font index vs the corresponding repertory | |
147 | char-table. | |
148 | ||
d6aaac9e KH |
149 | The 8th slot: |
150 | base: nil | |
151 | realized: If the base is not the default fontset, a fontset | |
152 | realized from the default fontset, else nil. | |
1d5d7200 | 153 | |
eb36588a | 154 | The 9th slot: |
cc7b6145 KH |
155 | base: Same as element value (but for fallback fonts). |
156 | realized: Likewise. | |
eb36588a | 157 | |
1d5d7200 | 158 | All fontsets are recorded in the vector Vfontset_table. |
0d407d77 KH |
159 | |
160 | ||
161 | DEFAULT FONTSET | |
162 | ||
1d5d7200 KH |
163 | There's a special base fontset named `default fontset' which |
164 | defines the default font specifications. When a base fontset | |
165 | doesn't specify a font for a specific character, the corresponding | |
166 | value in the default fontset is used. | |
0d407d77 | 167 | |
afe93d01 KH |
168 | The parent of a realized fontset created for such a face that has |
169 | no fontset is the default fontset. | |
0d407d77 KH |
170 | |
171 | ||
172 | These structures are hidden from the other codes than this file. | |
173 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d KH |
174 | usually use the variable name `fontset' for IDs. But, in this |
175 | file, we always use varialbe name `id' for IDs, and name `fontset' | |
1d5d7200 | 176 | for an actual fontset object, i.e., char-table. |
