An easy way to do C preprocessing!

Hi. From time to time I've seen people asking about how to do add C
preprocessing to their parser. An easy solution for that is the
CPreProcessorStream (Java based) that can now be download from


http://www.alphaworks.ibm.com/tech/cpreprocessor


It is coded by extending an InputStream and all data read from the
stream is preprocessed - so so you can concentrate on setting up your
own grammer wo. the c preprocessing.


It also takes care of #include so to your parser it will appear as if
was reading one large file (there is a method for getting file name
and line number from a cumulated line number). Also it is possible to
just extract #define definitions from header files (filtering all
other C syntax away).


Have a look for yourself.
