If explicit endings are introduced then the problem is trivial to solve.
MC_QUESTION :
NL INT ('.'|')') NOT_END+ ']' { out.print(q : ); };
fragment NOT_END :
~(']');
The most similar grammar I've found that deals with implicit endings is
the gherkin ragel lexer. Ideas for solving this

It's just hidden by default. Not sure how many people use it. To make it

I'm sorry. I didnt have the latest updates of all jars and so I could

After updating all, everything is ok.

You can either define abstract methods within @members and then subclass the
parser or you can create a subclass of Parser with the abstract methods or
concrete methods then use superClass. Also note you can create an interface for

I've already working on that. The problem is were to wrap?
Wouldn't the single-quoted dot just match literal dots only? Or is dot

I'd be interested in keeping IntelliJ plugin support in a combined

Something to consider if it is important to others.
