If you want to extract integer constants from your C/C++ file, you can
type this piece of code, written in CodeWorker, and save it in
"integers.cwp" :
    integers ::=
            // ignore C++-like comments between BNF symbols,
            // so that it doesn't read integers into comments
            #ignore(C++)
            [
                // jump to the next integer, and consume it
                ->[
                        #readInteger:iValue
                        // trace the integer on the console
                        => traceLine(iValue);
                    |
                        // if a string is encountered, consume it
                        // to not take into account the integers,
                        // which are perhaps into
                        #readCString
                ]
            ]* // search again
            ;


Then, download CodeWorker at "http://www.codeworker.org" and type the
command line:
    codeworker -parsebnf integers.cwp <your-C-file.c>


If you have more than one file to process, write the following lines
in the file "iterateSources.cws":
    forfile i in "*.c" {
        parseAsBNF("integers.cwp", project, i);
    }


and execute :
    codeworker iterateSources.cws


As CodeWorker is also a source code generator, you can choose to save
the integers in a file, following a template-based script, instead of
writing them on the console. You can also write the filename
(getInputFilename()), the line (countInputLines()) and column
(countInputCols()) where they were located.
