68 | ||
69 | A fontset is a collection of font related information to give | |
1d5d7200 KH |
70 | similar appearance (style, etc) of characters. A fontset has two |
71 | roles. One is to use for the frame parameter `font' as if it is an | |
72 | ASCII font. In that case, Emacs uses the font specified for | |
73 | `ascii' script for the frame's default font. | |
74 | ||
75 | Another role, the more important one, is to provide information | |
76 | about which font to use for each non-ASCII character. | |
77 | ||
78 | There are two kinds of fontsets; base and realized. A base fontset | |
79 | is created by `new-fontset' from Emacs Lisp explicitly. A realized | |
80 | fontset is created implicitly when a face is realized for ASCII | |
81 | characters. A face is also realized for non-ASCII characters based | |
82 | on an ASCII face. All of non-ASCII faces based on the same ASCII | |
83 | face share the same realized fontset. | |
8f924df7 | 84 | |
06f76f0d KH |
85 | A fontset object is implemented by a char-table whose default value |
86 | and parent are always nil. | |
fc8865fc | 87 | |
1d5d7200 KH |
88 | An element of a base fontset is a vector of FONT-DEFs which itself |
89 | is a vector [ FONT-SPEC ENCODING REPERTORY ]. | |
90 | ||
f088b054 KH |
91 | An element of a realized fontset is nil, t, 0, or a vector of this |
92 | form: | |
7e1a1cd9 | 93 | |
581f7ac7 KH |
94 | [ CHARSET-ORDERED-LIST-TICK PREFERRED-RFONT-DEF |
95 | RFONT-DEF0 RFONT-DEF1 ... ] | |
0d407d77 | 96 | |
7e1a1cd9 | 97 | RFONT-DEFn (i.e. Realized FONT-DEF) has this form: |
0d407d77 | 98 | |
581f7ac7 | 99 | [ FACE-ID FONT-DEF FONT-OBJECT SORTING-SCORE ] |
0d407d77 | 100 | |
581f7ac7 | 101 | RFONT-DEFn are automatically reordered by the current charset |
1d5d7200 | 102 | priority list. |
0d407d77 | 103 | |
7e1a1cd9 KH |
104 | The value nil means that we have not yet generated the above vector |
105 | from the base of the fontset. | |
0d407d77 | 106 | |
1d5d7200 KH |
107 | The value t means that no font is available for the corresponding |
108 | range of characters. | |
0d407d77 | 109 | |
f088b054 KH |
110 | The value 0 means that no font is available for the corresponding |
111 | range of characters in this fontset, but may be available in the | |
112 | default fontset. | |
113 | ||
0d407d77 | 114 | |
eb36588a | 115 | A fontset has 9 extra slots. |
0d407d77 | 116 | |
1d5d7200 | 117 | The 1st slot: the ID number of the fontset |
0d407d77 | 118 | |
1d5d7200 KH |
119 | The 2nd slot: |
120 | base: the name of the fontset | |
121 | realized: nil | |
0d407d77 | 122 | |
1d5d7200 | 123 | The 3rd slot: |
d6aaac9e | 124 | base: nil |
1d5d7200 | 125 | realized: the base fontset |
06f76f0d | 126 | |
1d5d7200 KH |
127 | The 4th slot: |
128 | base: nil | |
129 | realized: the frame that the fontset belongs to | |
0d407d77 | 130 | |
1d5d7200 KH |
131 | The 5th slot: |
132 | base: the font name for ASCII characters | |
133 | realized: nil | |
0d407d77 | 134 | |
1d5d7200 KH |
135 | The 6th slot: |
136 | base: nil | |
137 | realized: the ID number of a face to use for characters that | |
138 | has no font in a realized fontset. | |
0d407d77 | 139 | |
1d5d7200 KH |
140 | The 7th slot: |
141 | base: nil | |
142 | realized: Alist of font index vs the corresponding repertory | |
143 | char-table. | |
eb152aa9 | 144 | |
d6aaac9e KH |
145 | The 8th slot: |
146 | base: nil | |
147 | realized: If the base is not the default fontset, a fontset | |
148 | realized from the default fontset, else nil. | |
1d5d7200 | 149 | |
eb36588a | 150 | The 9th slot: |
cc7b6145 KH |
151 | base: Same as element value (but for fallback fonts). |
152 | realized: Likewise. | |
eb36588a | 153 | |
1d5d7200 | 154 | All fontsets are recorded in the vector Vfontset_table. |
0d407d77 KH |
155 | |
156 | ||
157 | DEFAULT FONTSET | |
158 | ||
1d5d7200 KH |
159 | There's a special base fontset named `default fontset' which |
160 | defines the default font specifications. When a base fontset | |
161 | doesn't specify a font for a specific character, the corresponding | |
162 | value in the default fontset is used. | |
0d407d77 | 163 | |
afe93d01 KH |
164 | The parent of a realized fontset created for such a face that has |
165 | no fontset is the default fontset. | |
0d407d77 KH |
166 | |
167 | ||
168 | These structures are hidden from the other codes than this file. | |
169 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d KH |
170 | usually use the variable name `fontset' for IDs. But, in this |
171 | file, we always use varialbe name `id' for IDs, and name `fontset' | |
1d5d7200 | 172 | for an actual fontset object, i.e., char-table. |
