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

1255 Implementing a general data structure that maps from arbitrary

1257 happens, it should suffice (and is usually more convenient, anyway)
1258 when dealing with characters to restrict the sorts of ranges that
1259 can be assigned values, as follows:
1262 2) All characters in a charset.
1263 3) All characters in a particular row of a charset, where a "row"
1264 means all characters with the same first byte.
1265 4) A particular character in a charset.
1267 We use char tables to generalize the 256-element vectors now
1268 littering the Emacs code.
1270 Possible uses (all should be converted at some point):
1276 5) keyboard-translate-table?

1704 A char table is a table that maps characters (or ranges of characters)

1706 particular sorts of ranges to be assigned values. Although this
1707 loses in generality, it makes for extremely fast (constant-time)
1708 lookups, and thus is feasible for applications that do an extremely
1709 large number of lookups (e.g. scanning a buffer for a character in
1710 a particular syntax, where a lookup in the syntax table must occur
1711 once per character).
1713 When Mule support exists, the types of ranges that can be assigned
1717 -- an entire charset
1718 -- a single row in a two-octet charset
1719 -- a single character
1721 When Mule support is not present, the types of ranges that can be
1725 -- a single character
1727 To create a char table, use `make-char-table'.
1728 To modify a char table, use `put-char-table' or `remove-char-table'.
1729 To retrieve the value for a particular character, use `get-char-table'.

4269 A category table is a type of char table used for keeping track of
4270 categories. Categories are used for classifying characters for use
4271 in regexps -- you can refer to a category rather than having to use
4272 a complicated [] expression (and category lookups are significantly
4275 There are 95 different categories available, one for each printable
4276 character (including space) in the ASCII charset. Each category
4277 is designated by one such character, called a "category designator".
4278 They are specified in a regexp using the syntax "\\cX", where X is
4279 a category designator.
4281 A category table specifies, for each character, the categories that
4282 the character is in. Note that a character can be in more than one
4283 category. More specifically, a category table maps from a character
4284 to either the value nil (meaning the character is in no categories)
4285 or a 95-element bit vector, specifying for each of the 95 categories
4286 whether the character is in that category.

4671 List of pair (cons) of categories to determine word boundary.
4673 Emacs treats a sequence of word constituent characters as a single
4674 word (i.e. finds no word boundary between them) iff they belongs to
4675 the same charset. But, exceptions are allowed in the following cases.
4677 \(1) The case that characters are in different charsets is controlled
4678 by the variable `word-combining-categories'.
4680 Emacs finds no word boundary between characters of different charsets
4681 if they have categories matching some element of this list.
4683 More precisely, if an element of this list is a cons of category CAT1
4684 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4685 C2 which has CAT2, there's no word boundary between C1 and C2.
4687 For instance, to tell that ASCII characters and Latin-1 characters can
4688 form a single word, the element `(?l . ?l)' should be in this list
4689 because both characters have the category `l' (Latin characters).
4691 \(2) The case that character are in the same charset is controlled by
4692 the variable `word-separating-categories'.
4694 Emacs find a word boundary between characters of the same charset
4695 if they have categories matching some element of this list.
4697 More precisely, if an element of this list is a cons of category CAT1
4698 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4699 C2 which has CAT2, there's a word boundary between C1 and C2.
4701 For instance, to tell that there's a word boundary between Japanese
4702 Hiragana and Japanese Kanji (both are in the same charset), the
4703 element `(?H . ?C) should be in this list.
