Besides checking with GHC which names are exported, we also need to keep all the docs attached to instance declarations (it is much tougher to detect when an instance is fully private). This change means: * slightly smaller interface files (7% reduction on boot libs) * slightly less work to do processing docstrings that aren't used * no warnings in Haddock's output about private docstrings (see #1070) I've tested manually that this does not affect any of the boot library generated docs (the only change in output was some small re-ordering in a handful of instance lists).

Also added some documention around `renameInterface`. Minimal signatures intentionally include references to potentially un-exported methods (see the discussion in #330), so it is expected that they will not always have a link destination. On the principle that warnings should always be resolvable, this shouldn't produce a warning.

For these cases, Haddock has to find a way to produce some synthetic sensible top-level declaration. This is done with `extractDecl`. As is shown by #1067, this is sometimes impossible to do just at a syntactic level (for instance when the subdecl is re-exported). In these cases, the only sensible thing to do is to try to reify a declaration based on a GHC `TyThing` via `hiDecl`. --- haddock-api/src/Haddock/Interface/Create.hs | 114 +++++++++++++++++----------- html-test/ref/Bug1067A.html | 114 ++++++++++++++++++++++++++++ html-test/ref/Bug1067B.html | 84 ++++++++++++++++++++ html-test/src/Bug1067A.hs | 9 +++ html-test/src/Bug1067B.hs | 4 + 5 files changed, 280 insertions(+), 45 deletions(-) create mode 100644 html-test/ref/Bug1067A.html create mode 100644 html-test/ref/Bug1067B.html create mode 100644 html-test/src/Bug1067A.hs create mode 100644 html-test/src/Bug1067B.hs (limited to 'haddock-api/src/Haddock/Interface/Create.hs') diff --git a/haddock-api/src/Haddock/Interface/Create.hs b/haddock-api/src/Haddock/Interface/Create.hs index 0f24afaa..5a58e1ac 100644 --- a/haddock-api/src/Haddock/Interface/Create.hs +++ b/haddock-api/src/Haddock/Interface/Create.hs @@ -793,11 +793,24 @@ availExportItem is_sig modMap thisMod semMod warnings exportedNames _ -> return [] + -- Tries 'extractDecl' first then falls back to 'hiDecl' if that fails + availDecl :: Name -> LHsDecl GhcRn -> ErrMsgGhc (LHsDecl GhcRn) + availDecl declName parentDecl = + case extractDecl declMap declName parentDecl of + Right d -> pure d + Left err -> do + synifiedDeclOpt <- hiDecl dflags declName + case synifiedDeclOpt of + Just synifiedDecl -> pure synifiedDecl + Nothing -> O.pprPanic "availExportItem" (O.text err) + availExportDecl :: AvailInfo -> LHsDecl GhcRn -> (DocForDecl Name, [(Name, DocForDecl Name)]) -> ErrMsgGhc [ ExportItem GhcRn ] availExportDecl avail decl (doc, subs) | availExportsDecl avail = do + extractedDecl <- availDecl (availName avail) decl + -- bundled pattern synonyms only make sense if the declaration is -- exported (otherwise there would be nothing to bundle to) bundledPatSyns <- findBundledPatterns avail @@ -813,8 +826,7 @@ availExportItem is_sig modMap thisMod semMod warnings exportedNames ] return [ ExportDecl { - expItemDecl = restrictTo (fmap fst subs) - (extractDecl declMap (availName avail) decl) + expItemDecl = restrictTo (fmap fst subs) extractedDecl , expItemPats = bundledPatSyns , expItemMbDoc = doc , expItemSubDocs = subs @@ -824,18 +836,18 @@ availExportItem is_sig modMap thisMod semMod warnings exportedNames } ] - | otherwise = - return [ ExportDecl { - expItemDecl = extractDecl declMap sub decl + | otherwise = for subs $ \(sub, sub_doc) -> do + extractedDecl <- availDecl sub decl + + return ( ExportDecl { + expItemDecl = extractedDecl , expItemPats = [] , expItemMbDoc = sub_doc , expItemSubDocs = [] , expItemInstances = [] , expItemFixities = [ (sub, f) | Just f <- [M.lookup sub fixMap] ] , expItemSpliced = False - } - | (sub, sub_doc) <- subs - ] + } ) exportedNameSet = mkNameSet exportedNames isExported n = elemNameSet n exportedNameSet @@ -910,6 +922,7 @@ semToIdMod this_uid m | Module.isHoleModule m = mkModule this_uid (moduleName m) | otherwise = m +-- | Reify a declaration from the GHC internal 'TyThing' representation. hiDecl :: DynFlags -> Name -> ErrMsgGhc (Maybe (LHsDecl GhcRn)) hiDecl dflags t = do mayTyThing <- liftGhcToErrMsgGhc $ lookupName t @@ -1053,20 +1066,30 @@ fullModuleContents is_sig modMap pkgName thisMod semMod warnings gre exportedNam isSigD (L _ SigD{}) = True isSigD _ = False + -- | Sometimes the declaration we want to export is not the "main" declaration: -- it might be an individual record selector or a class method.

To address this, I've changed the formatting in two ways: - the missing link symbol name is now fully qualified. This way you immediately know which haskell module cannot be linked. It is then easier to understand why this module does not have documentation (hidden module or broken documentation). - one line per missing link, that's more readable now that symbol name can be longer due to qualification. For example, before haddock was listing missing symbol such as: ``` could not find link destinations for: Word8 Word16 mapMaybe ``` Now it is listed as: ``` could not find link destinations for: - Data.Word.Word8 - Data.Word.Word16 - Data.Maybe.mapMaybe ``` * Add `--ignore-link-symbol` command line argument This argument can be used multiples time.
