f600cf3a | 49 | ;; where PROP is the same as above, and CHAR-TABLE is a |
1275c1dc | 50 | ;; char-table containing property values in a compressed format. |
f600cf3a KH |
51 | ;; |
52 | ;; When they are installed in .../lisp/international/, the file | |
53 | ;; "charprop.el" is preloaded in loadup.el. The other files are | |
c805dec0 KH |
54 | ;; automatically loaded when the Lisp functions |

58 | ;; FORMAT OF A CHAR TABLE | |
59 | ;; | |
60 | ;; We want to make a file size containing a char-table small. We | |
61 | ;; also want to load the file and get a property value fast. We | |
62 | ;; also want to reduce the used memory after loading it. So, | |
63 | ;; instead of naively storing a property value for each character in | |
64 | ;; a char-table (and write it out into a file), we store compressed | |
65 | ;; data in a char-table as below. | |
66 | ;; | |
67 | ;; If succeeding 128*N characters have the same property value, we | |
c805dec0 KH |
68 | ;; store that value (or the encoded one) for them. Otherwise, |
69 | ;; compress values (or the encoded ones) for succeeding 128 | |
70 | ;; characters into a single string and store it for those | |
71 | ;; characters. The way of compression depends on a property. See | |
72 | ;; the section "SIMPLE TABLE", "RUN-LENGTH TABLE", and "WORD-LIST | |
73 | ;; TABLE". | |
74 | ||
75 | ;; The char table has five extra slots: | |
f600cf3a | 76 | ;; 1st: property symbol |
c805dec0 KH |
77 | ;; 2nd: function to call to get a property value, |
78 | ;; or an index number of C function to decode the value, | |
79 | ;; or nil if the value can be directly got from the table. | |
80 | ;; 3nd: function to call to put a property value, | |
81 | ;; or an index number of C function to encode the value, | |
82 | ;; or nil if the value can be directly stored in the table. | |
83 | ;; 4th: function to call to get a description of a property value, or nil | |
f600cf3a | 84 | ;; 5th: data referred by the above functions |
