Support non-ASCII correctly in character classes, test this. src/ChangeLog addition: 2012-04-21 Aidan Kehoe <kehoea@parhasard.net> Support non-ASCII correctly in character classes ([:alnum:] and friends). * regex.c: * regex.c (ISBLANK, ISUNIBYTE): New. Make these and friends independent of the locale, since we want them to be consistent in XEmacs. * regex.c (print_partial_compiled_pattern): Print the flags for charset_mule; don't print non-ASCII as the character values in ranges, this breaks with locales. * regex.c (enum): Define various flags the charset_mule and charset_mule_not opcodes can now take. * regex.c (CHAR_CLASS_MAX_LENGTH): Update this. * regex.c (re_iswctype, re_wctype): New, from GNU. * regex.c (re_wctype_can_match_non_ascii): New; used when deciding on whether to use charset_mule or the ASCII-only regex character set opcode. * regex.c (regex_compile): Error correctly on long, non-existent character class names. Break out the handling of charsets that can match non-ASCII into a separate clause. Use compile_char_class when compiling character classes. * regex.c (compile_char_class): New. Used in regex_compile when compiling character sets that may match non-ASCII. * regex.c (re_compile_fastmap): If there are flags set for charset_mule or charset_mule_not, we can't use the fastmap (since we need to check syntax table values that aren't available there). * regex.c (re_match_2_internal): Check the new flags passed to the charset_mule{,_not} opcode, observe them if appropriate. * regex.h: * regex.h (enum): Expose re_wctype_t here, imported from GNU. tests/ChangeLog addition: 2012-04-21 Aidan Kehoe <kehoea@parhasard.net> * automated/regexp-tests.el: * automated/regexp-tests.el (Assert-char-class): Check that #'string-match errors correctly with an over-long character class name. Add tests for character class functionality that supports non-ASCII characters. These tests expose bugs in GNU Emacs 24.0.94.2, but pass under current XEmacs.

/* Hey Emacs, this is -*- C -*- code! */

/* Synched up with: Not synched with FSF. */

/* Think twice before editing this file.  Generated automatically by configure.

 The file startup.el guesses at reasonable values for load-path, exec-path,
 and lock-directory.  This means that if you move emacs and its associated
 sub-tree to a different place in the filesystem, or to a different machine,
 you won't have to do anything for it to work.

 If you define the paths in this file then they will take precedence over
 any value generated by the heuristic in startup.el.  The hardcoded paths
 will be checked to see if they are valid, in which case they will be used.
 Otherwise the editor will attempt to make its normal guess.

 See the NEWS file for a description of the heuristic used to locate the lisp
 and exec directories at startup time.  If you are looking at this file
 because you are having trouble, then you would be much better off arranging
 for those heuristics to succeed than defining the paths in this file.

   **  Let me say that again.  If you're editing this file, you're making
   **  a mistake.  Re-read the section on installation in ../etc/NEWS.

 If it defines anything, this file should define some subset of the following:

   PATH_PROGNAME        The name of the Emacs variant that's running.

   PATH_VERSION         The version id of the Emacs variant that's running.

   PATH_EXEC_PREFIX	The value of --exec-prefix.

   PATH_PREFIX		The value of --prefix.

   PATH_LOADSEARCH	The default value of `load-path'.

   PATH_MODULESEARCH	The default value of `module-load-path'.

   PATH_EARLY_PACKAGE_DIRECTORIES The value of `--with-early-packages'.
   PATH_LATE_PACKAGE_DIRECTORIES  The value of `--with-late-packages'.
   PATH_EARLY_PACKAGE_DIRECTORIES The value of `--with-last-packages'.

   PATH_PACKAGEPATH     The default value of `package-path'.

   PATH_SITE            The default location of site-specific Lisp files.

   PATH_SITE_MODULES	The default location of site-specific modules.

   PATH_EXEC		The default value of `exec-directory' and `exec-path'.
			(exec-path also contains the value of whatever is in
			the PATH environment variable.)

   PATH_DATA		The default value of `data-directory'.  This
			is where architecture-independent files are
			searched for.

   PATH_INFO		This is where the info documentation is installed.

   PATH_INFOPATH	The default value of `Info-directory-list'.
			These are additional places info files are searched
			for. */
