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