73 | ||
74 | A fontset is a collection of font related information to give | |
1d5d7200 KH |
75 | similar appearance (style, etc) of characters. A fontset has two |
76 | roles. One is to use for the frame parameter `font' as if it is an | |
77 | ASCII font. In that case, Emacs uses the font specified for | |
78 | `ascii' script for the frame's default font. | |
79 | ||
80 | Another role, the more important one, is to provide information | |
81 | about which font to use for each non-ASCII character. | |
82 | ||
83 | There are two kinds of fontsets; base and realized. A base fontset | |
84 | is created by `new-fontset' from Emacs Lisp explicitly. A realized | |
85 | fontset is created implicitly when a face is realized for ASCII | |
86 | characters. A face is also realized for non-ASCII characters based | |
87 | on an ASCII face. All of non-ASCII faces based on the same ASCII | |
88 | face share the same realized fontset. | |
8f924df7 | 89 | |
06f76f0d KH |
90 | A fontset object is implemented by a char-table whose default value |
91 | and parent are always nil. | |
fc8865fc | 92 | |
1d5d7200 KH |
93 | An element of a base fontset is a vector of FONT-DEFs which itself |
94 | is a vector [ FONT-SPEC ENCODING REPERTORY ]. | |
95 | ||
96 | FONT-SPEC is: | |
97 | [ FAMILY WEIGHT SLANT SWIDTH ADSTYLE REGISTRY ] | |
06f76f0d | 98 | or |
1d5d7200 KH |
99 | FONT-NAME |
100 | where FAMILY, WEIGHT, SLANT, SWIDTH, ADSTYLE, REGISTRY, and | |
101 | FONT-NAME are strings. | |
102 | ||
7e1a1cd9 KH |
103 | Note: Currently WEIGHT through ADSTYLE are ignored. |
104 | ||
57e13af9 KH |
105 | ENCODING is a charset ID that can convert characters to glyph codes |
106 | of the corresponding font. | |
1d5d7200 | 107 | |
57e13af9 KH |
108 | REPERTORY is a charset ID, a char-table, or nil. If REPERTORY is a |
109 | charset ID, the repertory of the charset exactly matches with that | |
110 | of the font. If REPERTORY is a char-table, all characters who have | |
111 | a non-nil value in the table are supported. If REPERTORY is nil, | |
112 | we consult with the font itself to get the repertory. | |
1d5d7200 KH |
113 | |
114 | ENCODING and REPERTORY are extracted from the variable | |
57e13af9 | 115 | Vfont_encoding_alist by using a font name generated from FONT-SPEC |
7e1a1cd9 | 116 | (if it is a vector) or FONT-NAME as a matching target. |
1d5d7200 KH |
117 | |
118 | ||
119 | An element of a realized fontset is nil or t, or has this form: | |
fc8865fc | 120 | |
7e1a1cd9 KH |
121 | [CHARSET-ORDERED-LIST-TICK PREFERRED-CHARSET-ID |
122 | PREFERRED-RFONT-DEF RFONT-DEF0 RFONT-DEF1 ...]. | |
0d407d77 | 123 | |
7e1a1cd9 | 124 | RFONT-DEFn (i.e. Realized FONT-DEF) has this form: |
0d407d77 | 125 | |
7e1a1cd9 | 126 | [ FACE-ID FONT-INDEX FONT-DEF OPENED-FONT-NAME ] |
0d407d77 | 127 | |
7e1a1cd9 | 128 | RFONT-DEFn is automatically reordered by the current charset |
1d5d7200 | 129 | priority list. |
0d407d77 | 130 | |
7e1a1cd9 KH |
131 | The value nil means that we have not yet generated the above vector |
132 | from the base of the fontset. | |
0d407d77 | 133 | |
1d5d7200 KH |
134 | The value t means that no font is available for the corresponding |
135 | range of characters. | |
0d407d77 | 136 | |
0d407d77 | 137 | |
eb36588a | 138 | A fontset has 9 extra slots. |
0d407d77 | 139 | |
1d5d7200 | 140 | The 1st slot: the ID number of the fontset |
0d407d77 | 141 | |
1d5d7200 KH |
142 | The 2nd slot: |
143 | base: the name of the fontset | |
144 | realized: nil | |
0d407d77 | 145 | |
1d5d7200 | 146 | The 3rd slot: |
d6aaac9e | 147 | base: nil |
1d5d7200 | 148 | realized: the base fontset |
06f76f0d | 149 | |
1d5d7200 KH |
150 | The 4th slot: |
151 | base: nil | |
152 | realized: the frame that the fontset belongs to | |
0d407d77 | 153 | |
1d5d7200 KH |
154 | The 5th slot: |
155 | base: the font name for ASCII characters | |
156 | realized: nil | |
0d407d77 | 157 | |
1d5d7200 KH |
158 | The 6th slot: |
159 | base: nil | |
160 | realized: the ID number of a face to use for characters that | |
161 | has no font in a realized fontset. | |
0d407d77 | 162 | |
1d5d7200 KH |
163 | The 7th slot: |
164 | base: nil | |
165 | realized: Alist of font index vs the corresponding repertory | |
166 | char-table. | |
167 | ||
d6aaac9e KH |
168 | The 8th slot: |
169 | base: nil | |
170 | realized: If the base is not the default fontset, a fontset | |
171 | realized from the default fontset, else nil. | |
1d5d7200 | 172 | |
eb36588a | 173 | The 9th slot: |
cc7b6145 KH |
174 | base: Same as element value (but for fallback fonts). |
175 | realized: Likewise. | |
eb36588a | 176 | |
1d5d7200 | 177 | All fontsets are recorded in the vector Vfontset_table. |
0d407d77 KH |
178 | |
179 | ||
180 | DEFAULT FONTSET | |
181 | ||
1d5d7200 KH |
182 | There's a special base fontset named `default fontset' which |
183 | defines the default font specifications. When a base fontset | |
184 | doesn't specify a font for a specific character, the corresponding | |
185 | value in the default fontset is used. | |
0d407d77 | 186 | |
afe93d01 KH |
187 | The parent of a realized fontset created for such a face that has |
188 | no fontset is the default fontset. | |
0d407d77 KH |
189 | |
190 | ||
191 | These structures are hidden from the other codes than this file. | |
192 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d KH |
193 | usually use the variable name `fontset' for IDs. But, in this |
194 | file, we always use varialbe name `id' for IDs, and name `fontset' | |
1d5d7200 | 195 | for an actual fontset object, i.e., char-table. |
