33 Ben Wing: wrote, for 19.13 (Mule). Some category table stuff
34 loosely based on the original Mule.
35 Jareth Hein: fixed a couple of bugs in the implementation, and
36 added regex support for categories with check_category_at

1265 happens, it should suffice (and is usually more convenient, anyway)
1266 when dealing with characters to restrict the sorts of ranges that
1267 can be assigned values, as follows:
1270 2) All characters in a charset.
1271 3) All characters in a particular row of a charset, where a "row"
1272 means all characters with the same first byte.
1273 4) A particular character in a charset.
1275 We use char tables to generalize the 256-element vectors now
1276 littering the Emacs code.
1278 Possible uses (all should be converted at some point):
1284 5) keyboard-translate-table?

1715 loses in generality, it makes for extremely fast (constant-time)

1717 large number of lookups (e.g. scanning a buffer for a character in
1718 a particular syntax, where a lookup in the syntax table must occur
1719 once per character).
1721 When Mule support exists, the types of ranges that can be assigned
1725 -- an entire charset
1726 -- a single row in a two-octet charset
1727 -- a single character
1729 When Mule support is not present, the types of ranges that can be

1735 To create a char table, use `make-char-table'.
1736 To modify a char table, use `put-char-table' or `remove-char-table'.
1737 To retrieve the value for a particular character, use `get-char-table'.

4370 A category table is a type of char table used for keeping track of
4371 categories. Categories are used for classifying characters for use
4372 in regexps -- you can refer to a category rather than having to use
4373 a complicated [] expression (and category lookups are significantly
4376 There are 95 different categories available, one for each printable
4377 character (including space) in the ASCII charset. Each category
4378 is designated by one such character, called a "category designator".
4379 They are specified in a regexp using the syntax "\\cX", where X is
4380 a category designator.
4382 A category table specifies, for each character, the categories that
4383 the character is in. Note that a character can be in more than one
4384 category. More specifically, a category table maps from a character
4385 to either the value nil (meaning the character is in no categories)
4386 or a 95-element bit vector, specifying for each of the 95 categories
4387 whether the character is in that category.

4778 Emacs treats a sequence of word constituent characters as a single
4779 word (i.e. finds no word boundary between them) iff they belongs to
4780 the same charset. But, exceptions are allowed in the following cases.
4782 \(1) The case that characters are in different charsets is controlled
4783 by the variable `word-combining-categories'.
4785 Emacs finds no word boundary between characters of different charsets
4786 if they have categories matching some element of this list.
4788 More precisely, if an element of this list is a cons of category CAT1
4789 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4790 C2 which has CAT2, there's no word boundary between C1 and C2.
4792 For instance, to tell that ASCII characters and Latin-1 characters can
4793 form a single word, the element `(?l . ?l)' should be in this list
4794 because both characters have the category `l' (Latin characters).
4796 \(2) The case that character are in the same charset is controlled by
4797 the variable `word-separating-categories'.
4799 Emacs find a word boundary between characters of the same charset
4800 if they have categories matching some element of this list.
4802 More precisely, if an element of this list is a cons of category CAT1
4803 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4804 C2 which has CAT2, there's a word boundary between C1 and C2.
4806 For instance, to tell that there's a word boundary between Japanese
4807 Hiragana and Japanese Kanji (both are in the same charset), the
4808 element `(?H . ?C) should be in this list.
