First, I wont generate cpp code with antlr.


After I send the inputfile to precompiler like cpp i get a document with lines like this:


#line 1 "includeTest2.txt"


now I wont parse this document and save the information for a better errormassage with the lexer rule like this:

			

			PREPROZLINE
			

			: "#line " i:NUMBER ' ' s:STRING_LITERAL ("
			

			"|'
			

			'|'
			

			')
			

			{
			

			setFilename(s->getText());
			

			setLine(i->getText());
			

			_ttype = ANTLR_USE_NAMESPACE(antlr)Token::SKIP;
			

			}
			

			;
		

first question:

is Inputstate place to store the filename or is this used by antlr for other things.

second question:

how can I get the filename in the errormassage, like:

			Error: filename(includeTest2.txt), line(5), expecting ID, found ';'
