Support predefined character classes in #'skip-chars-{forward,backward}, too src/ChangeLog addition: 2012-05-04 Aidan Kehoe <kehoea@parhasard.net> * regex.c: Move various #defines and enums to regex.h, since we need them when implementing #'skip-chars-{backward,forward}. * regex.c (re_wctype): * regex.c (re_iswctype): Be more robust about case insensitivity here. * regex.c (regex_compile): * regex.h: * regex.h (RE_ISWCTYPE_ARG_DECL): * regex.h (CHAR_CLASS_MAX_LENGTH): * search.c (skip_chars): Implement support for the predefined character classes in this function. tests/ChangeLog addition: 2012-05-04 Aidan Kehoe <kehoea@parhasard.net> * automated/regexp-tests.el (equal): * automated/regexp-tests.el (Assert-char-class): Correct a stray parenthesis; add tests for the predefined character classes with #'skip-chars-{forward,backward}; update the tests to reflect some changed design decisions on my part. man/ChangeLog addition: 2012-05-04 Aidan Kehoe <kehoea@parhasard.net> * lispref/searching.texi (Regular Expressions): * lispref/searching.texi (Syntax of Regexps): * lispref/searching.texi (Char Classes): * lispref/searching.texi (Regexp Example): Document the predefined character classes in this file.
