74 | ||
75 | A fontset is a collection of font related information to give | |
1d5d7200 KH |
76 | similar appearance (style, etc) of characters. A fontset has two |
77 | roles. One is to use for the frame parameter `font' as if it is an | |
78 | ASCII font. In that case, Emacs uses the font specified for | |
79 | `ascii' script for the frame's default font. | |
80 | ||
81 | Another role, the more important one, is to provide information | |
82 | about which font to use for each non-ASCII character. | |
83 | ||
84 | There are two kinds of fontsets; base and realized. A base fontset | |
85 | is created by `new-fontset' from Emacs Lisp explicitly. A realized | |
86 | fontset is created implicitly when a face is realized for ASCII | |
87 | characters. A face is also realized for non-ASCII characters based | |
88 | on an ASCII face. All of non-ASCII faces based on the same ASCII | |
89 | face share the same realized fontset. | |
8f924df7 | 90 | |
06f76f0d KH |
91 | A fontset object is implemented by a char-table whose default value |
92 | and parent are always nil. | |
fc8865fc | 93 | |
1d5d7200 KH |
94 | An element of a base fontset is a vector of FONT-DEFs which itself |
95 | is a vector [ FONT-SPEC ENCODING REPERTORY ]. | |
96 | ||
7ff614ed KH |
97 | FONT-SPEC is a font-spec created by `font-spec' or |
98 | ( FAMILY . REGISTRY ) | |
06f76f0d | 99 | or |
1d5d7200 | 100 | FONT-NAME |
7ff614ed | 101 | where FAMILY, REGISTRY, and FONT-NAME are strings. |
7e1a1cd9 | 102 | |
57e13af9 KH |
103 | ENCODING is a charset ID that can convert characters to glyph codes |
104 | of the corresponding font. | |
1d5d7200 | 105 | |
57e13af9 KH |
106 | REPERTORY is a charset ID, a char-table, or nil. If REPERTORY is a |
107 | charset ID, the repertory of the charset exactly matches with that | |
108 | of the font. If REPERTORY is a char-table, all characters who have | |
109 | a non-nil value in the table are supported. If REPERTORY is nil, | |
110 | we consult with the font itself to get the repertory. | |
1d5d7200 KH |
111 | |
112 | ENCODING and REPERTORY are extracted from the variable | |
57e13af9 | 113 | Vfont_encoding_alist by using a font name generated from FONT-SPEC |
7e1a1cd9 | 114 | (if it is a vector) or FONT-NAME as a matching target. |
1d5d7200 KH |
115 | |
116 | ||
117 | An element of a realized fontset is nil or t, or has this form: | |
fc8865fc | 118 | |
ea0162a6 KH |
119 | [CHARSET-ORDERED-LIST-TICK PREFERRED-CHARSET-ID PREFERRED-FAMILY |
120 | RFONT-DEF0 RFONT-DEF1 ...]. | |
0d407d77 | 121 | |
7e1a1cd9 | 122 | RFONT-DEFn (i.e. Realized FONT-DEF) has this form: |
0d407d77 | 123 | |
7e1a1cd9 | 124 | [ FACE-ID FONT-INDEX FONT-DEF OPENED-FONT-NAME ] |
0d407d77 | 125 | |
7e1a1cd9 | 126 | RFONT-DEFn is automatically reordered by the current charset |
1d5d7200 | 127 | priority list. |
0d407d77 | 128 | |
7e1a1cd9 KH |
129 | The value nil means that we have not yet generated the above vector |
130 | from the base of the fontset. | |
0d407d77 | 131 | |
1d5d7200 KH |
132 | The value t means that no font is available for the corresponding |
133 | range of characters. | |
0d407d77 | 134 | |
0d407d77 | 135 | |
eb36588a | 136 | A fontset has 9 extra slots. |
0d407d77 | 137 | |
1d5d7200 | 138 | The 1st slot: the ID number of the fontset |
0d407d77 | 139 | |
1d5d7200 KH |
140 | The 2nd slot: |
141 | base: the name of the fontset | |
142 | realized: nil | |
0d407d77 | 143 | |
1d5d7200 | 144 | The 3rd slot: |
d6aaac9e | 145 | base: nil |
1d5d7200 | 146 | realized: the base fontset |
06f76f0d | 147 | |
1d5d7200 KH |
148 | The 4th slot: |
149 | base: nil | |
150 | realized: the frame that the fontset belongs to | |
0d407d77 | 151 | |
1d5d7200 KH |
152 | The 5th slot: |
153 | base: the font name for ASCII characters | |
154 | realized: nil | |
0d407d77 | 155 | |
1d5d7200 KH |
156 | The 6th slot: |
157 | base: nil | |
158 | realized: the ID number of a face to use for characters that | |
159 | has no font in a realized fontset. | |
0d407d77 | 160 | |
1d5d7200 KH |
161 | The 7th slot: |
162 | base: nil | |
163 | realized: Alist of font index vs the corresponding repertory | |
164 | char-table. | |
165 | ||
d6aaac9e KH |
166 | The 8th slot: |
167 | base: nil | |
168 | realized: If the base is not the default fontset, a fontset | |
169 | realized from the default fontset, else nil. | |
1d5d7200 | 170 | |
eb36588a | 171 | The 9th slot: |
cc7b6145 KH |
172 | base: Same as element value (but for fallback fonts). |
173 | realized: Likewise. | |
eb36588a | 174 | |
1d5d7200 | 175 | All fontsets are recorded in the vector Vfontset_table. |
0d407d77 KH |
176 | |
177 | ||
178 | DEFAULT FONTSET | |
179 | ||
1d5d7200 KH |
180 | There's a special base fontset named `default fontset' which |
181 | defines the default font specifications. When a base fontset | |
182 | doesn't specify a font for a specific character, the corresponding | |
183 | value in the default fontset is used. | |
0d407d77 | 184 | |
afe93d01 KH |
185 | The parent of a realized fontset created for such a face that has |
186 | no fontset is the default fontset. | |
0d407d77 KH |
187 | |
188 | ||
189 | These structures are hidden from the other codes than this file. | |
190 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d KH |
191 | usually use the variable name `fontset' for IDs. But, in this |
192 | file, we always use varialbe name `id' for IDs, and name `fontset' | |
1d5d7200 | 193 | for an actual fontset object, i.e., char-table. |
