Haskell-ide-engine: Support for ghcjs

[xgrommx]

Hello @alanz Do u have some plans to add support for ghcjs? Also the same question about eta lang

[alanz]

No direct plans at the moment, the goal is currently to get something working properly for at least one GHC version.

That said, I do not think there is any specific reason that ghcjs should not work, nor eta so long as it has not diverged too much yet.

But we would need champions / PRs to actually do the work.

Any additional insight on this?

It would be a huge boon to be able to use projects like Miso and Reflex FRP.

I think the eta guys might be getting ready for some work on hie (or something similar), see https://github.com/rahulmutt/haskell-lsp/tree/ghc-7.10
