CUP has released version 0.11b

• CUP version 0.11b 20140808 is a feature/bugfix release.
  • added expected symbols to the report_error(...) method
  • added an expected_token_ids() to inform about valid continuations
  • added parameters and code to enable automatic creation of XML parse trees
  • fixed a bug in the lookahead computation
• CUP version 0.11b beta 20140226 is a feature release.
  • Command line flag -locations now triggers the generation of the identifiers
  • xleft and xright in the actions section instead of left and right.
  • Both are of type ComplexSymbolFactory.Location instead of plain ints.
• CUP version 0.11b beta 20140220 is a feature release.

Should we use it for the 1.6.1 release or leave the update for after that?

For me, latest dev version of JFlex 1.6.1 seems rock solid and corrects a long standing bug (#135) blocking us migrating from version 1.4.3, and should be released asap ;) So why introduce now potentially new problems by changing the cup version ? Of course, it's only my opinion! :)

Btw, there's even a newer cup version (0.11b 20150226) available on http://www2.cs.tum.edu/projects/cup/, but without any changelog.

I'm tending to leave it for the next release as well. Any objections?

I agree.

Hello,
I recently discovered that version 11b-20150226 had a nasty bug (introduced somewhere after v10k) that was corrected in latest 11b-20150326 version. In the changelog of cup it's described as :
"Fixed an issue with empty productions having non-empty location information".
It's about wrong position calculation of empty productions.

I was the original reporter of this bug to the maintainer of CUP.
I don't know if it impacts JFlex, but nevertheless, I still strongly advice you to make an additional update (to 11b-20150326), only a few files changed ;)

Thanks for reporting that. We should be on the latest even version of cup, but will double check.
