Vladislav Zavialov pushed to branch wip/int-index/tyop at Glasgow Haskell Compiler / GHC Commits: ae3491b0 by Vladislav Zavialov at 2026-03-03T02:12:25+03:00 Infix holes in types (#11107) This patch introduces several improvements that follow naturally from refactoring HsOpTy to represent the operator as an HsType, aligning it with the approach taken by OpApp and HsExpr. User-facing changes: 1. Infix holes (t1 `_` t2) are now permitted in types, following the precedent set by term-level expressions. Test case: T11107 2. Error messages for illegal promotion ticks are now reported at more precise source locations. Test case: T17865 Internal changes: * The definition of HsOpTy now mirrors that of OpApp: | HsOpTy (XOpTy p) (LHsType p) (LHsType p) (LHsType p) | OpApp (XOpApp p) (LHsExpr p) (LHsExpr p) (LHsExpr p) This moves us one step closer to unifying HsType and HsExpr. * Ignoring locations, the old pattern match (HsOpTy x prom lhs op rhs) is now written as (HsOpTy x lhs (HsTyVar x' prom op) rhs) but we also handle (HsOpTy x lhs (HsWildCardTy x') rhs) Constructors other than HsTyVar and HsWildCardTy never appear in the operator position. * The various definitions across the compiler have been updated to work with the new representation, drawing inspiration from the term-level pipeline where appropriate. For example, ppr_infix_ty <=> ppr_infix_expr get_tyop <=> get_op lookupTypeFixityRn <=> lookupExprFixityRn (the latter is factored out from rnExpr) Test cases: T11107 T17865 - - - - - 30 changed files: - compiler/GHC/Hs/Type.hs - compiler/GHC/Hs/Utils.hs - compiler/GHC/HsToCore/Quote.hs - compiler/GHC/Iface/Ext/Ast.hs - compiler/GHC/Parser.y - compiler/GHC/Parser/PostProcess.hs - compiler/GHC/Rename/Expr.hs - compiler/GHC/Rename/Fixity.hs - compiler/GHC/Rename/HsType.hs - compiler/GHC/Rename/Pat.hs - compiler/GHC/Tc/Gen/App.hs - compiler/GHC/Tc/Gen/HsType.hs - compiler/GHC/Tc/Gen/Pat.hs - compiler/GHC/Tc/Gen/Sig.hs - compiler/GHC/ThToHs.hs - compiler/Language/Haskell/Syntax/Type.hs - testsuite/tests/parser/should_compile/DumpParsedAst.stderr - testsuite/tests/parser/should_compile/DumpRenamedAst.stderr - testsuite/tests/parser/should_fail/T17865.stderr - + testsuite/tests/partial-sigs/should_compile/T11107.hs - + testsuite/tests/partial-sigs/should_compile/T11107.stderr - testsuite/tests/partial-sigs/should_compile/all.T - utils/check-exact/ExactPrint.hs - utils/haddock/haddock-api/src/Haddock/Backends/Hoogle.hs - utils/haddock/haddock-api/src/Haddock/Backends/LaTeX.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/Decl.hs - utils/haddock/haddock-api/src/Haddock/Convert.hs - utils/haddock/haddock-api/src/Haddock/GhcUtils.hs - utils/haddock/haddock-api/src/Haddock/Interface/Rename.hs - utils/haddock/haddock-api/src/Haddock/Interface/RenameType.hs Changes: ===================================== compiler/GHC/Hs/Type.hs ===================================== @@ -684,11 +684,12 @@ ignoreParens ty = ty mkAnonWildCardTy :: EpToken "_" -> HsType GhcPs mkAnonWildCardTy tok = HsWildCardTy tok -mkHsOpTy :: (Anno (IdOccGhcP p) ~ SrcSpanAnnN) +mkHsOpTy :: (Anno (IdOccGhcP p) ~ EpAnn a) => PromotionFlag - -> LHsType (GhcPass p) -> LocatedN (IdOccP (GhcPass p)) + -> LHsType (GhcPass p) -> LIdOccP (GhcPass p) -> LHsType (GhcPass p) -> HsType (GhcPass p) -mkHsOpTy prom ty1 op ty2 = HsOpTy noExtField prom ty1 op ty2 +mkHsOpTy prom ty1 op ty2 = HsOpTy noExtField ty1 tyop ty2 + where tyop = L (l2l op) $ HsTyVar noAnn prom op mkHsAppTy :: LHsType (GhcPass p) -> LHsType (GhcPass p) -> LHsType (GhcPass p) mkHsAppTy t1 t2 = addCLocA t1 t2 (HsAppTy noExtField t1 t2) @@ -746,7 +747,7 @@ hsTyGetAppHead_maybe = go go (L _ (HsTyVar _ _ ln)) = Just ln go (L _ (HsAppTy _ l _)) = go l go (L _ (HsAppKindTy _ t _)) = go t - go (L _ (HsOpTy _ _ _ ln _)) = Just ln + go (L _ (HsOpTy _ _ op _)) = go op go (L _ (HsParTy _ t)) = go t go (L _ (HsKindSig _ t _)) = go t go _ = Nothing @@ -1458,9 +1459,14 @@ ppr_mono_ty (HsAppTy _ fun_ty arg_ty) = hsep [ppr_mono_lty fun_ty, ppr_mono_lty arg_ty] ppr_mono_ty (HsAppKindTy _ ty k) = ppr_mono_lty ty <+> char '@' <> ppr_mono_lty k -ppr_mono_ty (HsOpTy _ prom ty1 (L _ op) ty2) - = sep [ ppr_mono_lty ty1 - , sep [pprOccWithTick Infix prom op, ppr_mono_lty ty2 ] ] +ppr_mono_ty (HsOpTy _ ty1 tyop ty2) + | Just pp_op <- ppr_infix_ty tyop + = sep [pp_ty1, sep [pp_op, pp_ty2]] + | otherwise + = hang (ppr tyop) 2 (sep [pp_ty1, pp_ty2]) + where + pp_ty1 = ppr_mono_lty ty1 + pp_ty2 = ppr_mono_lty ty2 ppr_mono_ty (HsParTy _ ty) = parens (ppr_mono_lty ty) -- Put the parens in where the user did @@ -1477,6 +1483,11 @@ ppr_mono_ty (XHsType t) = case ghcPass @p of HsRecTy _ flds -> pprHsConDeclRecFields flds GhcRn -> ppr t +ppr_infix_ty :: (OutputableBndrId p) => LHsType (GhcPass p) -> Maybe SDoc +ppr_infix_ty (L _ (HsTyVar _ prom (L _ op))) = Just (pprOccWithTick Infix prom op) +ppr_infix_ty (L _ (HsWildCardTy _)) = Just (text "`_`") +ppr_infix_ty _ = Nothing + -------------------------- ppr_fun_ty :: (OutputableBndrId p) => HsMultAnn (GhcPass p) -> LHsType (GhcPass p) -> LHsType (GhcPass p) -> SDoc ===================================== compiler/GHC/Hs/Utils.hs ===================================== @@ -632,7 +632,7 @@ nlHsTyConApp :: forall p a.
