The identifier parsing code is more precise and more efficient (although to be fair: it is also longer and in its own module). On the rendering side, we need to pipe through information about backticks/parens/neither all the way through from renaming to the backends. In terms of impact: a total of 35 modules in the entirety of the bootlib + ghc lib docs change. The only "regression" is things like '\0'. These should be changed to @\\0@ (the path by which this previously worked seems accidental). --- doc/markup.rst | 9 +- haddock-api/src/Haddock.hs | 2 +- haddock-api/src/Haddock/Backends/Hoogle.hs | 2 +- haddock-api/src/Haddock/Backends/LaTeX.hs | 19 +- .../src/Haddock/Backends/Xhtml/DocMarkup.hs | 16 +- haddock-api/src/Haddock/Backends/Xhtml/Names.hs | 28 +- haddock-api/src/Haddock/Interface/Json.hs | 5 +- haddock-api/src/Haddock/Interface/LexParseRn.hs | 58 +++-- haddock-api/src/Haddock/Interface/Rename.hs | 4 +- haddock-api/src/Haddock/InterfaceFile.hs | 27 +- haddock-api/src/Haddock/Parser.hs | 19 +- haddock-api/src/Haddock/Types.hs | 28 +- haddock-library/haddock-library.cabal | 2 + .../src/Documentation/Haddock/Parser.hs | 63 +---- .../src/Documentation/Haddock/Parser/Identifier.hs | 186 ++++++++++++++ .../src/Documentation/Haddock/Parser/Monad.hs | 13 +- .../test/Documentation/Haddock/ParserSpec.hs | 9 +- haddock.cabal | 1 + html-test/ref/Identifiers.html | 286 +++++++++++++++++++++ html-test/ref/Test.html | 2 +- html-test/src/Identifiers.hs | 35 +++ 21 files changed, 679 insertions(+), 135 deletions(-) create mode 100644 haddock-library/src/Documentation/Haddock/Parser/Identifier.hs create mode 100644 html-test/ref/Identifiers.html create mode 100644 html-test/src/Identifiers.hs (limited to 'html-test/ref') diff --git a/doc/markup.rst b/doc/markup.rst index 48a6f4ad..56238855 100644 --- a/doc/markup.rst +++ b/doc/markup.rst @@ -932,14 +932,9 @@ necessary to escape the single quote when used as an apostrophe: :: Nothing special is needed to hyperlink identifiers which contain apostrophes themselves: to hyperlink ``foo'`` one would simply type -``'foo''``.

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 'html-test/ref') 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.
