cannot deactivate System.err logs

[MLobatoR]

Hi,

I think you might forgot to comment System.err all over your code. I don't want to check them while running, just during debug. Is there a way that I can disable this?

Best regards,

Java or Dart? Which calls? Like the one in here?

antlr4/runtime/Java/src/org/antlr/v4/runtime/ConsoleErrorListener.java

Lines 31 to 39 in 6722835

	public void syntaxError(Recognizer<?, ?> recognizer,
	Object offendingSymbol,
	int line,
	int charPositionInLine,
	String msg,
	RecognitionException e)
	{
	System.err.println("line " + line + ":" + charPositionInLine + " " + msg);
	}

Hi @kaby76,

Java, And yes, like that one.

You need to remove the default error listeners and add your own, which can do anything it wishes.

	parser.removeErrorListeners();
	parser.addErrorListener( errorListener );

@jimidle I'll try that.

Thank you for your help.
