How generate the LL1 table and how use it ? about antlr4-intellij-adaptor HOT 4 OPEN

I found this function in the project antlr4 :

	protected void reportInputMismatch(Parser recognizer,
									   InputMismatchException e)
	{
		String msg = "mismatched input "+getTokenErrorDisplay(e.getOffendingToken())+
		" expecting "+e.getExpectedTokens().toString(recognizer.getVocabulary());
		recognizer.notifyErrorListeners(e.getOffendingToken(), msg, e);
	}

This function builds the description of PsiErrorElement.

Is it possible to add the function getExpectedTokens(offset) somewhere in your project ?

Or a method to read this list of tokens in my CompletionContributor class ?

You could try https://github.com/mike-lischke/antlr4-c3, which has a Java port. I might be possible to plug this library to a CompletionContributor.

Thanks, it works with
https://github.com/mike-lischke/antlr4-c3/blob/master/ports/java/src/main/java/com/vmware/antlr4c3/CodeCompletionCore.java

I will try to implement a basic list of token for the moment.

It's a very good idea to plug this library to a CompletionContributor 💯

I tested... May be I used bad this class but sometimes, there are not responses :(
