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

1257 Implementing a general data structure that maps from arbitrary

1259 happens, it should suffice (and is usually more convenient, anyway)
1260 when dealing with characters to restrict the sorts of ranges that
1261 can be assigned values, as follows:
1264 2) All characters in a charset.
1265 3) All characters in a particular row of a charset, where a "row"
1266 means all characters with the same first byte.
1267 4) A particular character in a charset.
1269 We use char tables to generalize the 256-element vectors now
1270 littering the Emacs code.
1272 Possible uses (all should be converted at some point):
1278 5) keyboard-translate-table?

1706 A char table is a table that maps characters (or ranges of characters)

1709 loses in generality, it makes for extremely fast (constant-time)
1710 lookups, and thus is feasible for applications that do an extremely
1711 large number of lookups (e.g. scanning a buffer for a character in
1712 a particular syntax, where a lookup in the syntax table must occur
1713 once per character).
1715 When Mule support exists, the types of ranges that can be assigned
1719 -- an entire charset
1720 -- a single row in a two-octet charset
1721 -- a single character
1723 When Mule support is not present, the types of ranges that can be
1727 -- a single character
1729 To create a char table, use `make-char-table'.
1730 To modify a char table, use `put-char-table' or `remove-char-table'.
1731 To retrieve the value for a particular character, use `get-char-table'.

4327 A category table is a type of char table used for keeping track of
4328 categories. Categories are used for classifying characters for use
4329 in regexps -- you can refer to a category rather than having to use
4330 a complicated [] expression (and category lookups are significantly
4333 There are 95 different categories available, one for each printable
4334 character (including space) in the ASCII charset. Each category
4335 is designated by one such character, called a "category designator".
4336 They are specified in a regexp using the syntax "\\cX", where X is
4337 a category designator.
4339 A category table specifies, for each character, the categories that
4340 the character is in. Note that a character can be in more than one
4341 category. More specifically, a category table maps from a character
4342 to either the value nil (meaning the character is in no categories)
4343 or a 95-element bit vector, specifying for each of the 95 categories
4344 whether the character is in that category.

4733 Emacs treats a sequence of word constituent characters as a single
4734 word (i.e. finds no word boundary between them) iff they belongs to
4735 the same charset. But, exceptions are allowed in the following cases.
4737 \(1) The case that characters are in different charsets is controlled
4738 by the variable `word-combining-categories'.
4740 Emacs finds no word boundary between characters of different charsets
4741 if they have categories matching some element of this list.
4743 More precisely, if an element of this list is a cons of category CAT1
4744 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4745 C2 which has CAT2, there's no word boundary between C1 and C2.
4747 For instance, to tell that ASCII characters and Latin-1 characters can
4748 form a single word, the element `(?l . ?l)' should be in this list
4749 because both characters have the category `l' (Latin characters).
4751 \(2) The case that character are in the same charset is controlled by
4752 the variable `word-separating-categories'.
4754 Emacs find a word boundary between characters of the same charset
4755 if they have categories matching some element of this list.
4757 More precisely, if an element of this list is a cons of category CAT1
4758 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4759 C2 which has CAT2, there's a word boundary between C1 and C2.
4761 For instance, to tell that there's a word boundary between Japanese
4762 Hiragana and Japanese Kanji (both are in the same charset), the
4763 element `(?H . ?C) should be in this list.
