mainland / exception-transformers Goto Github PK

I'd like to get language-c-quote back into Stack snapshots, and currently exception-transformers is a blocker due to too tight bounds on version 0.4.0.6.

exception-transformers is currently limited to to stm 2.4 at the latest, which does not support GHC 8.6.

which is on hackage now, but your package requires < 0.4.

Thanks!

I think this is the right package to report the bug on.

We're using language-c-quote to feed strange programs into feldspar-compiler for debugging purposes. We're also using QuickCheck for the test suite and there seems to be some funny interaction between transformers and exception-transformers on older versions of GHC. Here's a snippet of the build log (from https://travis-ci.org/Feldspar/feldspar-compiler/jobs/114312170):

I don't have an easy way to test older versions of GHC but with 7.8.3 I can build exception-transformers if I just bump the upper bound on transformers.

The current constraint (<0.6) prevents exception-transformers from building with current Stackage nightlies. I have verified that exception-transformers builds with transformers-compat-0.6.1.5.

The newest version of exception-transformers on Hackage is 0.4.0.6, but this repository contains only 0.4.0.5.

I see that 0c6e2e9 made this library compatible with transformers-0.6. Would it be possible to get that change up on hackage? Thank you!
