During lexical analyzing, I want to determine which file the lexer works on. How can I get this information during the Lexcial analyzing?

Hi,

what about calling CharString.getSourceName?

Hi Christian,

Thanks for your reply.
I have tried by the following code

@Override
	public void mTokens() throws RecognitionException {
		// TODO Auto-generated method stub
		super.mTokens();
		System.out.println("name = " + input.getSourceName());
	}

And, the result is "null".
Actually, I prefer to get the instance of IProject in the lexer.

Hi

the first one sounds like a bug to me (please file a bugzilla)
the second one like an enhancement request.
