This is important to prevent the final output from being more an more indented. See the `latext-test/src/Example` test case for a sample of this. * Support associated types in class declarations (but not yet defaults) * Several small issues for producing compiling LaTeX; - avoid empy `\haddockbeginargs` lists (ex: `type family Any`) - properly escape identifiers depending on context (ex: `Int#`) - add `vbox` around `itemize`/`enumerate` (so they can be in tables) * Several spacing fixes: - limit the width of `Pretty`-arranged monospaced code - cut out extra space characters in export lists - only escape spaces if there are _multiple_ spaces - allow type signatures to be multiline (even without docs) * Remove uninteresting and repetitive `main.tex`/`haddock.sty` files from `latex-test` test reference output.

Since this bug has been fixed upstream and that it doesn't have dire consequences anyways, the workaround is not really worth it anymore - we can just tell people to update their clang version (or re-structure their pragma code). --- haddock-api/haddock-api.cabal | 2 - haddock-api/src/Haddock/Backends/Hyperlinker.hs | 4 +- .../src/Haddock/Backends/Hyperlinker/Parser.hs | 47 +-------------------- .../Haddock/Backends/Hyperlinker/ParserSpec.hs | 49 ++++++++-------------- hypsrc-test/Main.hs | 9 +--- hypsrc-test/src/ClangCppBug.hs | 21 ---------- 6 files changed, 22 insertions(+), 110 deletions(-) delete mode 100644 hypsrc-test/src/ClangCppBug.hs (limited to 'haddock-api/src/Haddock') diff --git a/haddock-api/haddock-api.cabal b/haddock-api/haddock-api.cabal index a58b092a..5e8b37d8 100644 --- a/haddock-api/haddock-api.cabal +++ b/haddock-api/haddock-api.cabal @@ -59,7 +59,6 @@ library , directory , filepath , ghc-boot - , ghc-boot-th , transformers hs-source-dirs: src @@ -186,7 +185,6 @@ test-suite spec , directory , filepath , ghc-boot - , ghc-boot-th , transformers build-tool-depends: diff --git a/haddock-api/src/Haddock/Backends/Hyperlinker.hs b/haddock-api/src/Haddock/Backends/Hyperlinker.hs index 5ef7d9bb..251c886b 100644 --- a/haddock-api/src/Haddock/Backends/Hyperlinker.hs +++ b/haddock-api/src/Haddock/Backends/Hyperlinker.hs @@ -25,7 +25,6 @@ import FastString ( mkFastString ) import Module ( Module, moduleName ) import NameCache ( initNameCache ) import UniqSupply ( mkSplitUniqSupply ) -import SysTools.Info ( getCompilerInfo' ) -- | Generate hyperlinked source for given interfaces. @@ -62,12 +61,11 @@ ppHyperlinkedModuleSource srcdir pretty srcs iface = case ifaceHieFile iface of , hie_types = types , hie_hs_src = rawSrc } <- fmap fst (readHieFile (initNameCache u []) hfp) - comp <- getCompilerInfo' df -- Get the AST and tokens corresponding to the source file we want let mast | M.size asts == 1 = snd <$> M.lookupMin asts | otherwise = M.lookup (mkFastString file) asts - tokens = parse comp df file rawSrc + tokens = parse df file rawSrc -- Produce and write out the hyperlinked sources case mast of diff --git a/haddock-api/src/Haddock/Backends/Hyperlinker/Parser.hs b/haddock-api/src/Haddock/Backends/Hyperlinker/Parser.hs index 1d5576cc..0bd467e1 100644 --- a/haddock-api/src/Haddock/Backends/Hyperlinker/Parser.hs +++ b/haddock-api/src/Haddock/Backends/Hyperlinker/Parser.hs @@ -6,13 +6,9 @@ import Control.Applicative ( Alternative(..) ) import Data.List ( isPrefixOf, isSuffixOf ) import qualified Data.ByteString as BS -import qualified Data.ByteString.Char8 as BSC - -import GHC.LanguageExtensions.Type import BasicTypes ( IntegralLit(..) ) import DynFlags -import qualified EnumSet as E import ErrUtils ( emptyMessages ) import FastString ( mkFastString ) import Lexer ( P(..), ParseResult(..), PState(..), Token(..) @@ -29,12 +25,11 @@ import Haddock.GhcUtils -- Result should retain original file layout (including comments, -- whitespace, and CPP). parse - :: CompilerInfo -- ^ Underlying CC compiler (whatever expanded CPP) - -> DynFlags -- ^ Flags for this module + :: DynFlags -- ^ Flags for this module -> FilePath -- ^ Path to the source of this module -> BS.ByteString -- ^ Raw UTF-8 encoded source of this module -> [T.Token] -parse comp dflags fpath bs = case unP (go False []) initState of +parse dflags fpath bs = case unP (go False []) initState of POk _ toks -> reverse toks PFailed _ ss errMsg -> panic $ "Hyperlinker parse error at " ++ show ss ++ ": " ++ showSDoc dflags errMsg @@ -43,7 +38,6 @@ parse comp dflags fpath bs = case unP (go False []) initState of initState = mkPStatePure pflags buf start buf = stringBufferFromByteString bs start = mkRealSrcLoc (mkFastString fpath) 1 1 - needPragHack' = needPragHack comp dflags pflags = mkParserFlags' (warningFlags dflags) (extensionFlags dflags) (thisPackage dflags) @@ -125,12 +119,6 @@ parse comp dflags fpath bs = case unP (go False []) initState of pure (bEnd'', False) - -- See 'needPragHack' - ITclose_prag{} - | needPragHack' - , '\n' `BSC.elem` spaceBStr - -> getInput >>= \(b,p) -> setInput (b,advanceSrcLoc p '\n') >> pure (bEnd, False) - _ -> pure (bEnd, inPragDef) let tokBStr = splitStringBuffer bStart bEnd' @@ -155,37 +143,6 @@ parse comp dflags fpath bs = case unP (go False []) initState of pure ([unkTok], False) --- | This is really, really, /really/ gross.

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).

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') 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.

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.
