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'.

4358 A category table is a type of char table used for keeping track of
4359 categories. Categories are used for classifying characters for use
4360 in regexps -- you can refer to a category rather than having to use
4361 a complicated [] expression (and category lookups are significantly
4364 There are 95 different categories available, one for each printable
4365 character (including space) in the ASCII charset. Each category
4366 is designated by one such character, called a "category designator".
4367 They are specified in a regexp using the syntax "\\cX", where X is
4368 a category designator.
4370 A category table specifies, for each character, the categories that
4371 the character is in. Note that a character can be in more than one
4372 category. More specifically, a category table maps from a character
4373 to either the value nil (meaning the character is in no categories)
4374 or a 95-element bit vector, specifying for each of the 95 categories
4375 whether the character is in that category.

4764 Emacs treats a sequence of word constituent characters as a single
4765 word (i.e. finds no word boundary between them) iff they belongs to
4766 the same charset. But, exceptions are allowed in the following cases.
4768 \(1) The case that characters are in different charsets is controlled
4769 by the variable `word-combining-categories'.
4771 Emacs finds no word boundary between characters of different charsets
4772 if they have categories matching some element of this list.
4774 More precisely, if an element of this list is a cons of category CAT1
4775 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4776 C2 which has CAT2, there's no word boundary between C1 and C2.
4778 For instance, to tell that ASCII characters and Latin-1 characters can
4779 form a single word, the element `(?l . ?l)' should be in this list
4780 because both characters have the category `l' (Latin characters).
4782 \(2) The case that character are in the same charset is controlled by
4783 the variable `word-separating-categories'.
4785 Emacs find a word boundary between characters of the same charset
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 a word boundary between C1 and C2.
4792 For instance, to tell that there's a word boundary between Japanese
4793 Hiragana and Japanese Kanji (both are in the same charset), the
4794 element `(?H . ?C) should be in this list.
