[Feature] Provide Stan integration

[sir4ur0n]

I propose HLS supports Stan integration, what do you think?

[Ailrun]

I think it would be great if possible, but as they use .hie file, we cannot use them for GHC < 8.8...

P.S. You are at the Haskell Love Conference, aren't you? :)

Yes, and I wanted to link the existing HLS-Stan integration issue to others. That's how I noticed there is no issue yet 😛

Hi, I started with this, but have no particular branch yet.
I once had a somewhat working impl, but we need haskell/ghcide#701, too.

haskell/ghcide#701 is now in hls master, what additional work needs to be done to get this working? @fendor

A required step for sure would be create a plugin to provide stan diagnostics and refactorings (?). I think hls-hlint-plugin could be a good starting point.

[googleson78]

I was wondering if @fendor s work is something that's "almost done", and just needs a bit of cleanup.

[fendor]

@googleson78 The work got stalled, and it was not that much, so we should rather re-write it. I don't have anything workable at the moment :(

I will try to work on this.

As far as I understand, it required to add new Rule, which will call Stan runAnalysis for each project file.

[fendor]

Right, but ideally we re-use the .HIE files HLS is already generating, so we save some work.

@fendor @jneira

Stan requires HieTypes.HieFile while HLS GetHieAst returns HieAstResult, which contains only Module, not the whole file.
Is there any way to get HieTypes.HieFile out of HLS?
