* Copyright 1998-2000 Bertho A. Stultiens (BS)
|
|
*
|
|
* 21-May-2000 BS - Fixed the ident requirement of resource names
|
|
* which can be keywords.
|
|
* 30-Apr-2000 BS - Reintegration into the wine-tree
|
|
* 11-Jan-2000 BS - Very drastic cleanup because we don't have a
|
|
* preprocessor in here anymore.
|
|
* 02-Jan-2000 BS - Removed the preprocessor code
|
|
* 23-Dec-1999 BS - Removed the copyright for Martin von Loewis.
|
|
* There is really nothing left of his code in
|
|
* this parser.
|
|
* 20-Jun-1998 BS - Changed the filename conversion. Filenames are
|
|
* case-sensitive inder *nix, but not under dos.
|
|
* default behaviour is to convert to lower case.
|
|
* - All backslashes are converted to forward and
|
|
* both single and double slash is recognized as
|
|
* MS/Borland does.
|
|
* - Fixed a bug in 'yywf' case that prevented
|
|
* double quoted names to be scanned propperly.
|
|
*
|
|
* 19-May-1998 BS - Started to build a preprocessor.
|
|
* - Changed keyword processing completely to
|
|
* table-lookups.
|
|
*
|
|
* 20-Apr-1998 BS - Added ';' comment stripping
|
|
*
|
|
* 17-Apr-1998 BS - Made the win32 keywords optional when compiling in
|
|
* 16bit mode
|
|
*
|
|
* 15-Apr-1998 BS - Changed string handling to include escapes
|
|
* - Added unicode string handling (no codepage
|
|
* translation though).
|
|
* - 'Borrowed' the main idea of string scanning from
|
|
* the flex manual pages.
|
|
* - Added conditional handling of scanning depending
|
|
* on the state of the parser. This was mainly required
|
|
* to distinguish a file to load or raw data that
|
|
* follows. MS's definition of filenames is rather
|
|
* complex... It can be unquoted or double quoted. If
|
|
* double quoted, then the '\\' char is not automatically
|
|
* escaped according to Borland's rc compiler, but it
|
|
* accepts both "\\path\\file.rc" and "\path\file.rc".
|
|
* This makes life very hard! I go for the escaped
|
|
* version, as this seems to be the documented way...
|
|
* - Single quoted strings are now parsed and converted
|
|
* here.
|
|
* - Added comment stripping. The implementation is
|
|
* 'borrowed' from the flex manpages.
|
|
* - Rebuild string processing so that it may contain
|
|
* escaped '\0'.
