Subject: Fwd: State of BNFC-meta and friends
To: Haskell Cafe <haskell-cafe@haskell.org>


Dear cafe,

I tried to contact Jonas, the maintainer of BNFC-meta[1], twice
(a week ago and 1.5 months ago, see below the copies of emails)
with regards to updating the package to recent GHC, but with no luck.

I'm interested in taking over the package if nobody minds...

Kind regards, Artem

Hello Jonas,

I'm writing to let you know that your Hackage packages

* BNFS-meta,
* happy-meta,
* alex-meta

fail to build with current versions of GHC (8.6, 8.8). I wonder if you intend to update them?

All of them require bumping the template-haskell upper bound to <2.16.

happy-meta seems to have weird interactions with newer Cabal because of "Build-type: Custom" along the lines https://github.com/haskell/cabal/issues/5278 Given that your Setup.hs uses Distribution.Simple, I don't really see the point of having Custom. Switching to "Build-type: Simple" seems to work just fine.

alex-meta has one broken Monoid instance as per SMP proposal. Easily upgraded.

With these changes, I was able to build BNFC-meta successfully with GHC 8.6.5, cabal 2.4. I'd be happy to supply pull requests but I don't see {alex,happy}-meta repositories anywhere, and I noticed BNFC-meta repo on GitHub has the version of the package different from what is on Hackage.

There is a bunch of deprecation and tabs warnings also.

Kind regards,
