Hello, I am trying to find a way to incorporate a preprocessor in the ANTLR flow. I thought of doing this before the lexer, but I need to tokenize the incoming char stream for macro substitution to be easy. I thought of doing it between the lexer and the parser, and replace the preprocessor tokens with their expansion before feeding the token stream to the parser, so I guess I would end up using something like the TokenRewriteStream??? Can someone steer me in the right direction please? Or should I be using lexer rule actions? In which case, any example on how to access the token stream of the replacement token list of an identifier? Too many questions sorry.
The language I am hoping to tokenize is SystemVerilog and has C-like preprocessor macros (`include, `ifdef, `define NAME(params,...), token concatenation, etc.).
