58 | ||
59 | A fontset is a collection of font related information to give | |
1d5d7200 KH |
60 | similar appearance (style, etc) of characters. A fontset has two |
61 | roles. One is to use for the frame parameter `font' as if it is an | |
62 | ASCII font. In that case, Emacs uses the font specified for | |
63 | `ascii' script for the frame's default font. | |
64 | ||
65 | Another role, the more important one, is to provide information | |
66 | about which font to use for each non-ASCII character. | |
67 | ||
68 | There are two kinds of fontsets; base and realized. A base fontset | |
69 | is created by `new-fontset' from Emacs Lisp explicitly. A realized | |
70 | fontset is created implicitly when a face is realized for ASCII | |
71 | characters. A face is also realized for non-ASCII characters based | |
72 | on an ASCII face. All of non-ASCII faces based on the same ASCII | |
73 | face share the same realized fontset. | |
8f924df7 | 74 | |
06f76f0d KH |
75 | A fontset object is implemented by a char-table whose default value |
76 | and parent are always nil. | |
fc8865fc | 77 | |
1d5d7200 KH |
78 | An element of a base fontset is a vector of FONT-DEFs which itself |
79 | is a vector [ FONT-SPEC ENCODING REPERTORY ]. | |
80 | ||
81 | FONT-SPEC is: | |
82 | [ FAMILY WEIGHT SLANT SWIDTH ADSTYLE REGISTRY ] | |
06f76f0d | 83 | or |
1d5d7200 KH |
84 | FONT-NAME |
85 | where FAMILY, WEIGHT, SLANT, SWIDTH, ADSTYLE, REGISTRY, and | |
86 | FONT-NAME are strings. | |
87 | ||
7e1a1cd9 KH |
88 | Note: Currently WEIGHT through ADSTYLE are ignored. |
89 | ||
57e13af9 KH |
90 | ENCODING is a charset ID that can convert characters to glyph codes |
91 | of the corresponding font. | |
1d5d7200 | 92 | |
57e13af9 KH |
93 | REPERTORY is a charset ID, a char-table, or nil. If REPERTORY is a |
94 | charset ID, the repertory of the charset exactly matches with that | |
95 | of the font. If REPERTORY is a char-table, all characters who have | |
96 | a non-nil value in the table are supported. If REPERTORY is nil, | |
97 | we consult with the font itself to get the repertory. | |
1d5d7200 KH |
98 | |
99 | ENCODING and REPERTORY are extracted from the variable | |
57e13af9 | 100 | Vfont_encoding_alist by using a font name generated from FONT-SPEC |
7e1a1cd9 | 101 | (if it is a vector) or FONT-NAME as a matching target. |
1d5d7200 KH |
102 | |
103 | ||
104 | An element of a realized fontset is nil or t, or has this form: | |
fc8865fc | 105 | |
7e1a1cd9 KH |
106 | [CHARSET-ORDERED-LIST-TICK PREFERRED-CHARSET-ID |
107 | PREFERRED-RFONT-DEF RFONT-DEF0 RFONT-DEF1 ...]. | |
0d407d77 | 108 | |
7e1a1cd9 | 109 | RFONT-DEFn (i.e. Realized FONT-DEF) has this form: |
0d407d77 | 110 | |
7e1a1cd9 | 111 | [ FACE-ID FONT-INDEX FONT-DEF OPENED-FONT-NAME ] |
0d407d77 | 112 | |
7e1a1cd9 | 113 | RFONT-DEFn is automatically reordered by the current charset |
1d5d7200 | 114 | priority list. |
0d407d77 | 115 | |
7e1a1cd9 KH |
116 | The value nil means that we have not yet generated the above vector |
117 | from the base of the fontset. | |
0d407d77 | 118 | |
1d5d7200 KH |
119 | The value t means that no font is available for the corresponding |
120 | range of characters. | |
0d407d77 | 121 | |
0d407d77 | 122 | |
eb36588a | 123 | A fontset has 9 extra slots. |
0d407d77 | 124 | |
1d5d7200 | 125 | The 1st slot: the ID number of the fontset |
0d407d77 | 126 | |
1d5d7200 KH |
127 | The 2nd slot: |
128 | base: the name of the fontset | |
129 | realized: nil | |
0d407d77 | 130 | |
1d5d7200 | 131 | The 3rd slot: |
d6aaac9e | 132 | base: nil |
1d5d7200 | 133 | realized: the base fontset |
06f76f0d | 134 | |
1d5d7200 KH |
135 | The 4th slot: |
136 | base: nil | |
137 | realized: the frame that the fontset belongs to | |
0d407d77 | 138 | |
1d5d7200 KH |
139 | The 5th slot: |
140 | base: the font name for ASCII characters | |
141 | realized: nil | |
0d407d77 | 142 | |
1d5d7200 KH |
143 | The 6th slot: |
144 | base: nil | |
145 | realized: the ID number of a face to use for characters that | |
146 | has no font in a realized fontset. | |
0d407d77 | 147 | |
1d5d7200 KH |
148 | The 7th slot: |
149 | base: nil | |
150 | realized: Alist of font index vs the corresponding repertory | |
151 | char-table. | |
152 | ||
d6aaac9e KH |
153 | The 8th slot: |
154 | base: nil | |
155 | realized: If the base is not the default fontset, a fontset | |
156 | realized from the default fontset, else nil. | |
1d5d7200 | 157 | |
eb36588a | 158 | The 9th slot: |
cc7b6145 KH |
159 | base: Same as element value (but for fallback fonts). |
160 | realized: Likewise. | |
eb36588a | 161 | |
1d5d7200 | 162 | All fontsets are recorded in the vector Vfontset_table. |
0d407d77 KH |
163 | |
164 | ||
165 | DEFAULT FONTSET | |
166 | ||
1d5d7200 KH |
167 | There's a special base fontset named `default fontset' which |
168 | defines the default font specifications. When a base fontset | |
169 | doesn't specify a font for a specific character, the corresponding | |
170 | value in the default fontset is used. | |
0d407d77 | 171 | |
afe93d01 KH |
172 | The parent of a realized fontset created for such a face that has |
173 | no fontset is the default fontset. | |
0d407d77 KH |
174 | |
175 | ||
176 | These structures are hidden from the other codes than this file. | |
177 | The other codes handle fontsets only by their ID numbers. They | |
06f76f0d KH |
178 | usually use the variable name `fontset' for IDs. But, in this |
179 | file, we always use varialbe name `id' for IDs, and name `fontset' | |
1d5d7200 | 180 | for an actual fontset object, i.e., char-table. |
