Is there any way to add to 2 or more operands in a YACC project using the C language to build a parser for a LISP subset, this is the grammar
I\'m trying to write a parser for a Lua-like language, using lex and yacc. It is a language without a f开发者_Go百科orced statement terminator(a semicolon), and this feature made me not able to tell i

I am using Yacc and lex to parse a C type language , I have built the data structures using c++. everything works fine but i am not able to read the input file using yyin in main.cpp.
curs.l : %{ #include <stdlib.h> #include \"tree.c\" #include \"yycurs.h\" %} L [a-zA-Z_] D [0-9] D4 [0-3]
I hope the title clarifies what I want to ask because it is a bit tricky. I have a SCONS SConscript for every subdir as follows (doing it in linux, if it matters):
