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

1258 Implementing a general data structure that maps from arbitrary

1260 happens, it should suffice (and is usually more convenient, anyway)
1261 when dealing with characters to restrict the sorts of ranges that
1262 can be assigned values, as follows:
1265 2) All characters in a charset.
1266 3) All characters in a particular row of a charset, where a "row"
1267 means all characters with the same first byte.
1268 4) A particular character in a charset.
1270 We use char tables to generalize the 256-element vectors now

1273 Possible uses (all should be converted at some point):
1279 5) keyboard-translate-table?

1707 A char table is a table that maps characters (or ranges of characters)

1709 particular sorts of ranges to be assigned values. Although this
1710 loses in generality, it makes for extremely fast (constant-time)
1711 lookups, and thus is feasible for applications that do an extremely
1712 large number of lookups (e.g. scanning a buffer for a character in
1713 a particular syntax, where a lookup in the syntax table must occur
1714 once per character).
1716 When Mule support exists, the types of ranges that can be assigned
1720 -- an entire charset
1721 -- a single row in a two-octet charset
1722 -- a single character
1724 When Mule support is not present, the types of ranges that can be
1728 -- a single character
1730 To create a char table, use `make-char-table'.
1731 To modify a char table, use `put-char-table' or `remove-char-table'.
1732 To retrieve the value for a particular character, use `get-char-table'.

4413 A category table is a type of char table used for keeping track of
4414 categories. Categories are used for classifying characters for use
4415 in regexps -- you can refer to a category rather than having to use
4416 a complicated [] expression (and category lookups are significantly
4419 There are 95 different categories available, one for each printable
4420 character (including space) in the ASCII charset. Each category
4421 is designated by one such character, called a "category designator".
4422 They are specified in a regexp using the syntax "\\cX", where X is
4423 a category designator.
4425 A category table specifies, for each character, the categories that
4426 the character is in. Note that a character can be in more than one
4427 category. More specifically, a category table maps from a character
4428 to either the value nil (meaning the character is in no categories)
4429 or a 95-element bit vector, specifying for each of the 95 categories
4430 whether the character is in that category.
4432 Special Lisp functions are provided that abstract this, so you do not
4433 have to directly manipulate bit vectors.

4820 Emacs treats a sequence of word constituent characters as a single
4821 word (i.e. finds no word boundary between them) iff they belongs to
4822 the same charset. But, exceptions are allowed in the following cases.
4824 \(1) The case that characters are in different charsets is controlled
4825 by the variable `word-combining-categories'.
4827 Emacs finds no word boundary between characters of different charsets
4828 if they have categories matching some element of this list.
4830 More precisely, if an element of this list is a cons of category CAT1
4831 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4832 C2 which has CAT2, there's no word boundary between C1 and C2.
4834 For instance, to tell that ASCII characters and Latin-1 characters can
4835 form a single word, the element `(?l . ?l)' should be in this list
4836 because both characters have the category `l' (Latin characters).
4838 \(2) The case that character are in the same charset is controlled by
4839 the variable `word-separating-categories'.
4841 Emacs find a word boundary between characters of the same charset
4842 if they have categories matching some element of this list.
4844 More precisely, if an element of this list is a cons of category CAT1
4845 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4846 C2 which has CAT2, there's a word boundary between C1 and C2.
4848 For instance, to tell that there's a word boundary between Japanese
4849 Hiragana and Japanese Kanji (both are in the same charset), the
4850 element `(?H . ?C) should be in this list.
