[antlr-interest] Re: CLI with ANTLR - best practice

[thierryj8]

It seems easy to catch the exceptions in the parser
ls
  : ls	  
  exception
  catch [RecognitionException ex] {
    System.out.println("command");
  }
  ;

but it's not obvious how to catch the default exception

  throw new NoViableAltForCharException((char)LA(1), getFilename(),
getLine(), getColumn());

in the lexer.

Possibly the exceptions should be handled in the parser, and the lexer
exceptions should be turned off?
