75 | ||
76 | A fontset is a collection of font related information to give | |
1d5d7200 KH |
77 | similar appearance (style, etc) of characters. A fontset has two |
78 | roles. One is to use for the frame parameter `font' as if it is an | |
79 | ASCII font. In that case, Emacs uses the font specified for | |
80 | `ascii' script for the frame's default font. | |
81 | ||
82 | Another role, the more important one, is to provide information | |
83 | about which font to use for each non-ASCII character. | |
84 | ||
85 | There are two kinds of fontsets; base and realized. A base fontset | |
86 | is created by `new-fontset' from Emacs Lisp explicitly. A realized | |
87 | fontset is created implicitly when a face is realized for ASCII | |
88 | characters. A face is also realized for non-ASCII characters based | |
89 | on an ASCII face. All of non-ASCII faces based on the same ASCII | |
90 | face share the same realized fontset. | |
8f924df7 | 91 | |
06f76f0d KH |
92 | A fontset object is implemented by a char-table whose default value |
93 | and parent are always nil. | |
fc8865fc | 94 | |
1d5d7200 KH |
95 | An element of a base fontset is a vector of FONT-DEFs which itself |
96 | is a vector [ FONT-SPEC ENCODING REPERTORY ]. | |
97 | ||
98 | FONT-SPEC is: | |
99 | [ FAMILY WEIGHT SLANT SWIDTH ADSTYLE REGISTRY ] | |
06f76f0d | 100 | or |
1d5d7200 KH |
101 | FONT-NAME |
102 | where FAMILY, WEIGHT, SLANT, SWIDTH, ADSTYLE, REGISTRY, and | |
103 | FONT-NAME are strings. | |
104 | ||
7e1a1cd9 KH |
105 | Note: Currently WEIGHT through ADSTYLE are ignored. |
106 | ||
57e13af9 KH |
107 | ENCODING is a charset ID that can convert characters to glyph codes |
108 | of the corresponding font. | |
1d5d7200 | 109 | |
57e13af9 KH |
110 | REPERTORY is a charset ID, a char-table, or nil. If REPERTORY is a |
111 | charset ID, the repertory of the charset exactly matches with that | |
112 | of the font. If REPERTORY is a char-table, all characters who have | |
113 | a non-nil value in the table are supported. If REPERTORY is nil, | |
114 | we consult with the font itself to get the repertory. | |
1d5d7200 KH |
115 | |
116 | ENCODING and REPERTORY are extracted from the variable | |
57e13af9 | 117 | Vfont_encoding_alist by using a font name generated from FONT-SPEC |
7e1a1cd9 | 118 | (if it is a vector) or FONT-NAME as a matching target. |
1d5d7200 KH |
119 | |
120 | ||
121 | An element of a realized fontset is nil or t, or has this form: | |
fc8865fc | 122 | |
7e1a1cd9 KH |
123 | [CHARSET-ORDERED-LIST-TICK PREFERRED-CHARSET-ID |
124 | PREFERRED-RFONT-DEF RFONT-DEF0 RFONT-DEF1 ...]. | |
0d407d77 | 125 | |
7e1a1cd9 | 126 | RFONT-DEFn (i.e. Realized FONT-DEF) has this form: |
0d407d77 | 127 | |
7e1a1cd9 | 128 | [ FACE-ID FONT-INDEX FONT-DEF OPENED-FONT-NAME ] |
0d407d77 | 129 | |
7e1a1cd9 | 130 | RFONT-DEFn is automatically reordered by the current charset |
1d5d7200 | 131 | priority list. |
0d407d77 | 132 | |
7e1a1cd9 KH |
133 | The value nil means that we have not yet generated the above vector |
134 | from the base of the fontset. | |
0d407d77 | 135 | |
1d5d7200 KH |
136 | The value t means that no font is available for the corresponding |
137 | range of characters. | |
0d407d77 | 138 | |
0d407d77 | 139 | |
eb36588a | 140 | A fontset has 9 extra slots. |
0d407d77 | 141 | |
1d5d7200 | 142 | The 1st slot: the ID number of the fontset |
0d407d77 | 143 | |
1d5d7200 KH |
144 | The 2nd slot: |
145 | base: the name of the fontset | |
146 | realized: nil | |
0d407d77 | 147 | |
1d5d7200 | 148 | The 3rd slot: |
d6aaac9e | 149 | base: nil |
1d5d7200 | 150 | realized: the base fontset |
06f76f0d | 151 | |
1d5d7200 KH |
152 | The 4th slot: |
153 | base: nil | |
154 | realized: the frame that the fontset belongs to | |
0d407d77 | 155 | |
1d5d7200 KH |
156 | The 5th slot: |
157 | base: the font name for ASCII characters | |
158 | realized: nil | |
0d407d77 | 159 | |
1d5d7200 KH |
160 | The 6th slot: |
161 | base: nil | |
162 | realized: the ID number of a face to use for characters that | |
163 | has no font in a realized fontset. | |
0d407d77 | 164 | |
1d5d7200 KH |
165 | The 7th slot: |
166 | base: nil | |
167 | realized: Alist of font index vs the corresponding repertory | |
168 | char-table. | |
169 | ||
d6aaac9e KH |
170 | The 8th slot: |
171 | base: nil | |
172 | realized: If the base is not the default fontset, a fontset | |
173 | realized from the default fontset, else nil. | |
1d5d7200 | 174 | |
eb36588a | 175 | The 9th slot: |
cc7b6145 KH |
176 | base: Same as element value (but for fallback fonts). |
177 | realized: Likewise. | |
eb36588a | 178 | |
1d5d7200 | 179 | All fontsets are recorded in the vector Vfontset_table. |
0d407d77 KH |
180 | |
181 | ||
182 | DEFAULT FONTSET | |
183 | ||
1d5d7200 KH |
184 | There's a special base fontset named `default fontset' which |
185 | defines the default font specifications. When a base fontset | |
186 | doesn't specify a font for a specific character, the corresponding | |
187 | value in the default fontset is used. | |
0d407d77 | 188 | |
afe93d01 KH |
189 | The parent of a realized fontset created for such a face that has |
190 | no fontset is the default fontset. | |
0d407d77 KH |
191 | |
192 | ||
193 | These structures are hidden from the other codes than this file. | |
194 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d KH |
195 | usually use the variable name `fontset' for IDs. But, in this |
196 | file, we always use varialbe name `id' for IDs, and name `fontset' | |
1d5d7200 | 197 | for an actual fontset object, i.e., char-table. |
