30 | ;; | |

32 | ;; the current directory. |
33 | ;; | |
34 | ;; charprop.el | |
35 | ;; It contains a series of forms of this format: | |
36 | ;; (char-code-property-register PROP FILE) | |
37 | ;; where PROP is a symbol representing a character property | |
1275c1dc | 38 | ;; (name, generic-category, etc), and FILE is a name of one of |
f600cf3a KH |
39 | ;; the following files. |
40 | ;; | |
dd7d19d7 JB |
41 | ;; uni-name.el, uni-category.el, uni-combining.el, uni-bidi.el, |
42 | ;; uni-decomposition.el, uni-decimal.el, uni-digit.el, uni-numeric.el, | |
43 | ;; uni-mirrored.el, uni-old-name.el, uni-comment.el, uni-uppercase.el, | |
44 | ;; uni-lowercase.el, uni-titlecase.el | |
45 | ;; They each contain a single form of this format: | |
f600cf3a KH |
46 | ;; (char-code-property-register PROP CHAR-TABLE) |
47 | ;; where PROP is the same as above, and CHAR-TABLE is a | |
1275c1dc | 48 | ;; char-table containing property values in a compressed format. |
f600cf3a KH |
49 | ;; |
50 | ;; When they are installed in .../lisp/international/, the file | |
51 | ;; "charprop.el" is preloaded in loadup.el. The other files are | |
52 | ;; automatically loaded when the functions `get-char-code-property' | |
53 | ;; and `put-char-code-property' are called. | |
54 | ;; | |
55 | ;; FORMAT OF A CHAR TABLE | |
56 | ;; | |
57 | ;; We want to make a file size containing a char-table small. We | |
58 | ;; also want to load the file and get a property value fast. We | |
59 | ;; also want to reduce the used memory after loading it. So, | |
60 | ;; instead of naively storing a property value for each character in | |
61 | ;; a char-table (and write it out into a file), we store compressed | |
62 | ;; data in a char-table as below. | |
63 | ;; | |
64 | ;; If succeeding 128*N characters have the same property value, we | |
1275c1dc | 65 | ;; store that value for them. Otherwise, compress values for |
f600cf3a KH |
66 | ;; succeeding 128 characters into a single string and store it as a |
67 | ;; value for those characters. The way of compression depends on a | |
68 | ;; property. See the section "SIMPLE TABLE", "RUN-LENGTH TABLE", | |
69 | ;; and "WORD-LIST TABLE". | |
70 | ||
71 | ;; The char table has four extra slots: | |
72 | ;; 1st: property symbol | |
73 | ;; 2nd: function to call to get a property value | |
74 | ;; 3nd: function to call to put a property value | |
75 | ;; 4th: function to call to get a description of a property value | |
76 | ;; 5th: data referred by the above functions | |
