From 87fbc11227347da805a3d2158d462514438ca742 Mon Sep 17 00:00:00 2001 From: Ryan Scott Date: Sun, 5 Apr 2020 11:48:39 -0400 Subject: Fix #1050 by filtering out invisible AppTy arguments This makes the `synifyType` case for `AppTy` more intelligent by taking into consideration the visibilities of each `AppTy` argument and filtering out any invisible arguments, as they aren't intended to be displayed in the source code. (See #1050 for an example of what can happen if you fail to filter these out.) Along the way, I noticed that a special `synifyType` case for `AppTy t1 (CoercionTy {})` could be consolidated with the case below it, so I took the opportunity to tidy this up. --- html-test/src/Bug1050.hs | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 html-test/src/Bug1050.hs (limited to 'html-test/src') diff --git a/html-test/src/Bug1050.hs b/html-test/src/Bug1050.hs new file mode 100644 index 00000000..ea293e6e --- /dev/null +++ b/html-test/src/Bug1050.hs @@ -0,0 +1,11 @@ +{-# LANGUAGE GADTs #-} +{-# LANGUAGE PolyKinds #-} +{-# LANGUAGE RankNTypes #-} +module Bug1050 where + +import Data.Kind + +newtype T :: (forall k. k -> Type) -> (forall k. k -> Type) where + MkT :: forall (f :: forall k. k -> Type) k (a :: k). f a -> T f a + +mkT = MkT -- cgit v1.2.3
