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