56 | /* FONTSET |
57 | ||
58 | A fontset is a collection of font related information to give | |
1d5d7200 KH |
59 | similar appearance (style, etc) of characters. A fontset has two |
60 | roles. One is to use for the frame parameter `font' as if it is an | |
61 | ASCII font. In that case, Emacs uses the font specified for | |
62 | `ascii' script for the frame's default font. | |
63 | ||
64 | Another role, the more important one, is to provide information | |
65 | about which font to use for each non-ASCII character. | |
66 | ||
67 | There are two kinds of fontsets; base and realized. A base fontset | |
68 | is created by `new-fontset' from Emacs Lisp explicitly. A realized | |
69 | fontset is created implicitly when a face is realized for ASCII | |
70 | characters. A face is also realized for non-ASCII characters based | |
71 | on an ASCII face. All of non-ASCII faces based on the same ASCII | |
72 | face share the same realized fontset. | |
8f924df7 | 73 | |
06f76f0d KH |
74 | A fontset object is implemented by a char-table whose default value |
75 | and parent are always nil. | |
fc8865fc | 76 | |
1d5d7200 KH |
77 | An element of a base fontset is a vector of FONT-DEFs which itself |
78 | is a vector [ FONT-SPEC ENCODING REPERTORY ]. | |
79 | ||
f088b054 KH |
80 | An element of a realized fontset is nil, t, 0, or a vector of this |
81 | form: | |
7e1a1cd9 | 82 | |
581f7ac7 KH |
83 | [ CHARSET-ORDERED-LIST-TICK PREFERRED-RFONT-DEF |
84 | RFONT-DEF0 RFONT-DEF1 ... ] | |
0d407d77 | 85 | |
7e1a1cd9 | 86 | RFONT-DEFn (i.e. Realized FONT-DEF) has this form: |
0d407d77 | 87 | |
581f7ac7 | 88 | [ FACE-ID FONT-DEF FONT-OBJECT SORTING-SCORE ] |
0d407d77 | 89 | |
581f7ac7 | 90 | RFONT-DEFn are automatically reordered by the current charset |
1d5d7200 | 91 | priority list. |
0d407d77 | 92 | |
7e1a1cd9 KH |
93 | The value nil means that we have not yet generated the above vector |
94 | from the base of the fontset. | |
0d407d77 | 95 | |
1d5d7200 KH |
96 | The value t means that no font is available for the corresponding |
97 | range of characters. | |
0d407d77 | 98 | |
f088b054 KH |
99 | The value 0 means that no font is available for the corresponding |
100 | range of characters in this fontset, but may be available in the | |
101 | default fontset. | |
102 | ||
0d407d77 | 103 | |
eb36588a | 104 | A fontset has 9 extra slots. |
0d407d77 | 105 | |
1d5d7200 | 106 | The 1st slot: the ID number of the fontset |
0d407d77 | 107 | |
1d5d7200 KH |
108 | The 2nd slot: |
109 | base: the name of the fontset | |
110 | realized: nil | |
0d407d77 | 111 | |
1d5d7200 | 112 | The 3rd slot: |
d6aaac9e | 113 | base: nil |
1d5d7200 | 114 | realized: the base fontset |
06f76f0d | 115 | |
1d5d7200 KH |
116 | The 4th slot: |
117 | base: nil | |
118 | realized: the frame that the fontset belongs to | |
0d407d77 | 119 | |
1d5d7200 KH |
120 | The 5th slot: |
121 | base: the font name for ASCII characters | |
122 | realized: nil | |
0d407d77 | 123 | |
1d5d7200 KH |
124 | The 6th slot: |
125 | base: nil | |
126 | realized: the ID number of a face to use for characters that | |
127 | has no font in a realized fontset. | |
0d407d77 | 128 | |
1d5d7200 KH |
129 | The 7th slot: |
130 | base: nil | |
131 | realized: Alist of font index vs the corresponding repertory | |
132 | char-table. | |
eb152aa9 | 133 | |
d6aaac9e KH |
134 | The 8th slot: |
135 | base: nil | |
136 | realized: If the base is not the default fontset, a fontset | |
137 | realized from the default fontset, else nil. | |
1d5d7200 | 138 | |
eb36588a | 139 | The 9th slot: |
cc7b6145 KH |
140 | base: Same as element value (but for fallback fonts). |
141 | realized: Likewise. | |
eb36588a | 142 | |
1d5d7200 | 143 | All fontsets are recorded in the vector Vfontset_table. |
0d407d77 KH |
144 | |
145 | ||
146 | DEFAULT FONTSET | |
147 | ||
1d5d7200 KH |
148 | There's a special base fontset named `default fontset' which |
149 | defines the default font specifications. When a base fontset | |
150 | doesn't specify a font for a specific character, the corresponding | |
151 | value in the default fontset is used. | |
0d407d77 | 152 | |
afe93d01 KH |
153 | The parent of a realized fontset created for such a face that has |
154 | no fontset is the default fontset. | |
0d407d77 KH |
155 | |
156 | ||
157 | These structures are hidden from the other codes than this file. | |
158 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d | 159 | usually use the variable name `fontset' for IDs. But, in this |
c80e3b4a | 160 | file, we always use variable name `id' for IDs, and name `fontset' |
1d5d7200 | 161 | for an actual fontset object, i.e., char-table. |
