From 730a2163245cf7aaf389458113e6fa338eca7865 Mon Sep 17 00:00:00 2001 From: Alec Theriault Date: Sat, 28 Mar 2020 12:04:16 -0400 Subject: Use TTG empty extensions to remove some `error`'s None of these error cases should ever have been reachable, so this is just a matter of leveraging the type system to assert this. * Use the `NoExtCon` and `noExtCon` to handle case matches for no extension constructors, instead of throwing an `error`. * Use the extension field of `HsSpliceTy` to ensure that this variant of `HsType` cannot exist in an `HsType DocNameI`. --- haddock-api/src/Haddock/Interface/Specialize.hs | 17 +++++------------ 1 file changed, 5 insertions(+), 12 deletions(-) (limited to 'haddock-api/src/Haddock/Interface/Specialize.hs') diff --git a/haddock-api/src/Haddock/Interface/Specialize.hs b/haddock-api/src/Haddock/Interface/Specialize.hs index 03cc1b7e..19b03596 100644 --- a/haddock-api/src/Haddock/Interface/Specialize.hs +++ b/haddock-api/src/Haddock/Interface/Specialize.hs @@ -9,6 +9,7 @@ module Haddock.Interface.Specialize ) where +import Haddock.GhcUtils ( hsTyVarBndrName ) import Haddock.Syb import Haddock.Types @@ -56,13 +57,9 @@ specialize specs = go spec_map0 -- Again, it is just a convenience function around 'specialize'.
