From 3de72a80fff18aa71873ace86d1aeb5171b09b41 Mon Sep 17 00:00:00 2001 From: Ben Gamari Date: Wed, 16 Dec 2015 06:05:25 -0500 Subject: Fix fallout from wildcards refactoring The wildcard refactoring was introduced a new type of signature, `ClassOpSig`, which is carried by typeclasses. The original patch adapting Haddock for this change missed a few places where this constructor needed to be handled, resulting in no class methods in documentation produced by Haddock. Additionally, this moves and renames the `isVanillaLSig` helper from GHC's HsBinds module into GhcUtils, since it is only used by Haddock. --- haddock-api/src/Haddock/Backends/Xhtml/Decl.hs | 4 ++-- haddock-api/src/Haddock/GhcUtils.hs | 18 ++++++++++++++---- haddock-api/src/Haddock/Interface/Create.hs | 6 +++--- haddock-api/src/Haddock/Interface/Rename.hs | 4 ++++ 4 files changed, 23 insertions(+), 9 deletions(-) (limited to 'haddock-api') diff --git a/haddock-api/src/Haddock/Backends/Xhtml/Decl.hs b/haddock-api/src/Haddock/Backends/Xhtml/Decl.hs index d27cb2bc..49149b8c 100644 --- a/haddock-api/src/Haddock/Backends/Xhtml/Decl.hs +++ b/haddock-api/src/Haddock/Backends/Xhtml/Decl.hs @@ -451,7 +451,7 @@ ppShortClassDecl :: Bool -> LinksInfo -> TyClDecl DocName -> SrcSpan ppShortClassDecl summary links (ClassDecl { tcdCtxt = lctxt, tcdLName = lname, tcdTyVars = tvs , tcdFDs = fds, tcdSigs = sigs, tcdATs = ats }) loc subdocs splice unicode qual = - if not (any isVanillaLSig sigs) && null ats + if not (any isUserLSig sigs) && null ats then (if summary then id else topDeclElem links loc splice [nm]) hdr else (if summary then id else topDeclElem links loc splice [nm]) (hdr <+> keyword "where") +++ shortSubDecls False @@ -492,7 +492,7 @@ ppClassDecl summary links instances fixities loc d subdocs sigs = map unLoc lsigs classheader - | any isVanillaLSig lsigs = topDeclElem links loc splice [nm] (hdr unicode qual <+> keyword "where" <+> fixs) + | any isUserLSig lsigs = topDeclElem links loc splice [nm] (hdr unicode qual <+> keyword "where" <+> fixs) | otherwise = topDeclElem links loc splice [nm] (hdr unicode qual <+> fixs) -- Only the fixity relevant to the class header diff --git a/haddock-api/src/Haddock/GhcUtils.hs b/haddock-api/src/Haddock/GhcUtils.hs index 2a9fba2e..4e5e008b 100644 --- a/haddock-api/src/Haddock/GhcUtils.hs +++ b/haddock-api/src/Haddock/GhcUtils.hs @@ -95,6 +95,10 @@ filterSigNames p (TypeSig ns ty) = case filter (p . unLoc) ns of [] -> Nothing filtered -> Just (TypeSig filtered ty) +filterSigNames p (ClassOpSig is_default ns ty) = + case filter (p . unLoc) ns of + [] -> Nothing + filtered -> Just (ClassOpSig is_default filtered ty) filterSigNames _ _ = Nothing ifTrueJust :: Bool -> name -> Maybe name @@ -105,13 +109,19 @@ sigName :: LSig name -> [name] sigName (L _ sig) = sigNameNoLoc sig sigNameNoLoc :: Sig name -> [name] -sigNameNoLoc (TypeSig ns _) = map unLoc ns -sigNameNoLoc (PatSynSig n _) = [unLoc n] -sigNameNoLoc (SpecSig n _ _) = [unLoc n] -sigNameNoLoc (InlineSig n _) = [unLoc n] +sigNameNoLoc (TypeSig ns _) = map unLoc ns +sigNameNoLoc (ClassOpSig _ ns _) = map unLoc ns +sigNameNoLoc (PatSynSig n _) = [unLoc n] +sigNameNoLoc (SpecSig n _ _) = [unLoc n] +sigNameNoLoc (InlineSig n _) = [unLoc n] sigNameNoLoc (FixSig (FixitySig ns _)) = map unLoc ns sigNameNoLoc _ = [] +-- | Was this signature given by the user?
