Haskell-ide-engine: GHC 8.8.1-rc1 is out

I wonder if we can use it to try building HIE with cabal and file some dependency bugs and/or fix some easily fixed breakage, e.g. due to MonadFail.

I read on Reddit the plan was for 8.8 to hit stack nightly after lts-14 is released.
Does anyone know where the status of lts-14 is being tracked?
It will be much easier to fix hie once we have a stack nightly to work with.

Stack LTS 14 is out now

8.8 is finally out now, just not on windows, I don't think stack nightly will include 8.8 until the windows build is ready.

Has anyone had any luck getting haskell-ide-engine running on GHC 8.8.1? I've gotten as far as the brittany and apply-refact dependencies, which seem to depend on GHC internals that have changed. I tried making them depend on ghc-lib to no avail.

I got stuck at hslogger.

haskell-ide-engine depends on hslogger.

Choosing an older hslogger doesn't work: Versions of hslogger less than 1.3.0.0 require and old network <2.9, and all stackage 8.8.1 snapshots have a newer network 3.1.1.0.

Choosing a newer hslogger doesn't work: Versions of hslogger 1.3.0.0 and greater introduce a dependency on network-bsd, and network-bsd requires an old network <3.1.1. There is an open issue in network-bsd about this: https://github.com/haskell/network-bsd/issues/6

I started on it, but with https://github.com/haskell/haskell-ide-engine/pull/1126 hopefully landing soon I will defer until afterwards.

Also to keep track, hare is depending on https://github.com/haskell-infra/hackage-trustees/issues/244#issuecomment-544140731

There is a pr to make hie ghc-8.8.1 compatible: #1482 that will close this one
