JavaCC Version 5.0 released.

[Paul Cager-5]

Hi All,

I'm pleased to announce the release of version 5.0 of JavaCC, which is
available for download from the Project and Files location,
https://javacc.dev.java.net/servlets/ProjectDocumentList.

As well as a number of bug fixes, release 5.0 generates Java 5.0 style
code by default (at last!).

Regards,
Paul Cager

Hello.

What about a way to ensure that, at certain points of the grammar, backing up a single token is safe and, that a next token exists?

I use the former for error recovery, but I do not know if it won't cause weird lexer/parser behavior in some cases.

I can ensure the latter by adding artificial choices to the grammar, but I still do not know if it works in all cases.

As of me, such features would add a bit of flexibility that one has with hand--made parsers.

But, perhaps there is virtually no demand for the features among JavaCC users.

Best regards,
Artur

That's an interesting idea.... you might want to file an issue here:

Just to keep it on the radar.

Yours,
