Hi


I tried to get the IDENTIFIER names from a C/C++ File like follow ...


main()
{
    int a,b;
    a = 5;
}


.. so I put an action after the concerned reduction like this ...


rescoped.identifier:
IDENTIFIER { printf("IDENTIFIER = '%s'\n", $1); }


| operator.function.name


                | class.rescoped.identifier
                ;


.. after that the output looked like this ...


IDENTIFIER = 'a'
IDENTIFIER = 'b'
IDENTIFIER = '='


Please note: - the cutting is a part from the Roskind cpp4.y grammer.
- I didn't want to get the names from all IDENTIFIER's,
only the simple-ones like above.
- the program is originated from cpp4.l (LEXFILE ROSKIND)
cpp4.y (YACCFILE ROSKIND)
- I had the same problem with: YACC/LEX, YACC/FLEX, BYACC/LEX




Im happy about every advice !
Thanks for your endevour.
