* Changes from #14579Ryan Scott2019-11-031-22/+5
| | | | | | | We now have a top-level `tyConAppNeedsKindSig` function, which means that we can delete lots of code in `Convert`. (cherry picked from commit cfd682c5fd03b099a3d78c44f9279faf56a0ac70)
* Reify oversaturated data family instances correctly (#1103)Ryan Scott2019-10-231-15/+23
| | | | | | This fixes #1103 by adapting the corresponding patch for GHC (see https://gitlab.haskell.org/ghc/ghc/issues/17296 and https://gitlab.haskell.org/ghc/ghc/merge_requests/1877).
* Fix #1015 with dataConUserTyVars (#1022)Ryan Scott2019-02-041-3/+4
| | | | | | | The central trick in this patch is to use `dataConUserTyVars` instead of `univ_tvs ++ ex_tvs`, which displays the foralls in a GADT constructor in a way that's more faithful to how the user originally wrote it. Fixes #1015.
* Miscellaneous improvements to `Convert` (#1020)Alec Theriault2019-02-031-143/+322
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that Haddock is moving towards working entirely over `.hi` and `.hie` files, all declarations and types are going to be synthesized via the `Convert` module. In preparation for this change, here are a bunch of fixes to this module: * Add kind annotations to type variables in `forall`'s whose kind is not `Type`, unless the kind can be inferred from some later use of the variable. See `implicitForAll` and `noKindTyVars` in particular if you wish to dive into this. * Properly detect `HsQualTy` in `synifyType`. This is done by following suit with what GHC's `toIfaceTypeX` does and checking the first argument of `FunTy{} :: Type` to see if it classified as a given/wanted in the typechecker (see `isPredTy`). * Beef up the logic around figuring out when an explicit `forall` is needed. This includes: observing if any of the type variables will need kind signatures, if the inferred type variable order _without_ a forall will still match the one GHC claims, and some other small things. * Add some (not yet used) functionality for default levity polymorphic type signatures. This functionality similar to `fprint-explicit-runtime-reps`. Couple other smaller fixes only worth mentioning: * Show the family result signature only when it isn't `Type` * Fix rendering of implicit parameters in the LaTeX and Hoogle backends * Better handling of the return kind of polykinded H98 data declarations * Class decls produced by `tyThingToLHsDecl` now contain associated type defaults and default method signatures when appropriate * Filter out more `forall`'s in pattern synonyms

* Only look at visible types when synifying a 'HsListTy'Alec Theriault2018-09-031-1/+1
| | | | | The other types are still looked at when considering whether to make a kind signature or not.
* Properly synify promoted list typesAlec Theriault2018-08-271-1/+15
| | | | | | | | | | | We reconstruct promoted list literals whenever possible. That means that 'synifyType' produces '[Int, Bool, ()] instead of (Int ': (() ': (Bool ': ([] :: [Type]))))
* Handle promoted tuples in 'synifyType'Alec Theriault2018-08-211-0/+4
| | | | When we have a fully applied promoted tuple, we can expand it out properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removes the call to `patSynType :: PatSyn -> Type` in `Convert.hs` as this function will be removed from GHC. Instead, we use the function `patSynSig` and build the `HsDecl` manually. This also fixes the printing of the two contexts and the quantified type variables in a pattern synonym type.
