Hi I am trying to implement a single line comment in my lexer. I
looked at the java.g single line comment. It works great if a
newline is at the end of the comment, but fails when an EOF is
encountered, saying
unexpected char: ?
I browsed through the archives and message 4617 talks about this
problem.
SL_COMMENT
: "//"
(~('\n'|'\r'))* ('\n'|'\r'('\n')?)
{$setType(Token.SKIP); newline();}
;
