* Remove workaround for now-fixed Clang CPP bug (#1028)Alec Theriault2019-03-292-48/+3
| | | | | | | | | | | Before LLVM 6.0.1 (or 10.0 on Apple LLVM), there was a bug where lines that started with an octothorpe but turned out not to lex like pragmas would have an extra line added after them. 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).
* Many LaTeX backend fixesAlec Theriault2019-03-091-98/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | After this commit, we can run with `--latex` on all boot libraries without crashing (although the generated LaTeX still fails to compile in a handful of larger packages like `ghc` and `base`). * Add newlines after all block elements in LaTeX. 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. Fixes #935, #929 (LaTeX docs for `text` build & compile) Fixes #727, #930 (I think both are really about type families...)
* Avoid multi-line `emph` in LaTeX backendAlec Theriault2019-03-091-1/+1
| | | | | | | | `markupWarning` often processes inputs which span across paragraphs. Unfortunately, LaTeX's `emph` is not made to handle this (and will crash). Fixes #936.
* Better support for default methods in classesAlec Theriault2019-03-094-51/+102
| | | | | | | | | | * default methods now get rendered differently * default associated types get rendered * fix a forgotten `s/TypeSig/ClassOpSig/` refactor in LaTeX backend * LaTeX backend now renders default method signatures NB: there is still no way to document default class members and the NB: LaTeX backend still crashes on associated types
* Merge branch 'ghc-8.6' into ghc-8.8Alec Theriault2019-03-037-77/+78

| * Fix standalone deriving docsAlec Theriault2019-02-251-2/+2

| | | | | | | | | | | | | | The information about whether or not there is a source-level `forall` is already available on a `ConDecl` (as `con_forall`), so we should use it instead of always assuming `False`! Fixes #1002.

* | Fix bogus identifier defaultingAlec Theriault2019-02-261-9/+5
| | | | | | | | | | | | | | | | This avoids a situation in which an identifier would get defaulted to a completely different identifier. Prior to this commit, the 'Bug1035' test case would hyperlink 'Foo' into 'Bar'! Fixes #1035.
* | Better identifier parsingAlec Theriault2019-02-2510-65/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * '(<|>)' and '`elem`' now get parsed and rendered properly as links * 'DbModule'/'DbUnitId' now properly get split apart into two links * tuple names now get parsed properly * some more small niceties... 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).
* | Support value/type namespaces on identifier linksAlec Theriault2019-02-254-21/+56
| | | | | | | | | | | | | | | | | | | | | | Identifier links can be prefixed with a 'v' or 't' to indicate the value or type namespace of the desired identifier. For example: -- | Some link to a value: v'Data.Functor.Identity' -- -- Some link to a type: t'Data.Functor.Identity' The default is still the type (with a warning about the ambiguity)
* | Fix #1015 with dataConUserTyVars (#1022)Ryan Scott2019-02-041-3/+4
| | | | | | | | | | | | | | The central trick in this patch is to use `dataConUserTyVars` instead of `univ_tvs ++ ex_tvs`, which displays the foralls in a GADT constructor in a way that's more faithful to how the user originally wrote it. Fixes #1015.
* | Miscellaneous improvements to `Convert` (#1020)Alec Theriault2019-02-035-152/+444
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that Haddock is moving towards working entirely over `.hi` and `.hie` files, all declarations and types are going to be synthesized via the `Convert` module. In preparation for this change, here are a bunch of fixes to this module: * Add kind annotations to type variables in `forall`'s whose kind is not `Type`, unless the kind can be inferred from some later use of the variable. See `implicitForAll` and `noKindTyVars` in particular if you wish to dive into this. * Properly detect `HsQualTy` in `synifyType`. This is done by following suit with what GHC's `toIfaceTypeX` does and checking the first argument of `FunTy{} :: Type` to see if it classified as a given/wanted in the typechecker (see `isPredTy`). * Beef up the logic around figuring out when an explicit `forall` is needed. This includes: observing if any of the type variables will need kind signatures, if the inferred type variable order _without_ a forall will still match the one GHC claims, and some other small things. * Add some (not yet used) functionality for default levity polymorphic type signatures. This functionality similar to `fprint-explicit-runtime-reps`. Couple other smaller fixes only worth mentioning: * Show the family result signature only when it isn't `Type` * Fix rendering of implicit parameters in the LaTeX and Hoogle backends * Better handling of the return kind of polykinded H98 data declarations * Class decls produced by `tyThingToLHsDecl` now contain associated type defaults and default method signatures when appropriate * Filter out more `forall`'s in pattern synonyms
* | Use `.hie` files for the Hyperlinker backend (#977)Alec Theriault2019-01-3111-650/+688
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | # Summary This is a large architectural change to the Hyperlinker. * extract link (and now also type) information from `.hie` instead of doing ad-hoc SYB traversals of the `RenamedSource`. Also adds a superb type-on-hover feature (#715). * re-engineer the lexer to avoid needless string conversions. By going directly through GHC's `P` monad and taking bytestring slices, we avoid a ton of allocation and have better handling of position pragmas and CPP. In terms of performance, the Haddock side of things has gotten _much_ more efficient. Unfortunately, much of this is cancelled out by the increased GHC workload for generating `.hie` files. For the full set of boot libs (including `ghc`-the-library) * the sum of total time went down by 9-10% overall * the sum of total allocations went down by 6-7% # Motivation Haddock is moving towards working entirely over `.hi` and `.hie` files. This change means we no longer need the `RenamedSource` from `TypecheckedModule` (something which is _not_ in `.hi` files). # Details Along the way a bunch of things were fixed: * Cross package (and other) links are now more reliable (#496) * The lexer tries to recover from errors on every line (instead of at CPP boundaries) * `LINE`/`COLUMN` pragmas are taken into account * filter out zero length tokens before rendering * avoid recomputing the `ModuleName`-based `SrcMap` * remove the last use of `Documentation.Haddock.Utf8` (see #998) * restructure temporary folder logic for `.hi`/`.hie` model

* | [TTG: Handling Source Locations] Foundation and PatShayan-Najd2018-11-237-36/+75
| | | | | | | | | | | | | | | | | | | | | | Trac Issues #15495 This patch removes the ping-pong style from HsPat (only, for now), using the plan laid out at https://ghc.haskell.org/trac/ghc/wiki/ImplementingTreesThatGrow/HandlingSourceLocations (solution A). - the class `HasSrcSpan`, and its functions (e.g., `cL` and `dL`), are introduced - some instances of `HasSrcSpan` are introduced - some constructors `L` are replaced with `cL` - some patterns `L` are replaced with `dL->L` view pattern - some type annotation are necessarily updated (e.g., `Pat p` --> `Pat (GhcPass p)`)

| | | | | | | | | | | | | | | | | | | | | | | | AFAICT this wasn't causing any crashes, but that's mostly because we happen not to be forcing `pkgStr` when it would diverge. We come dangerously close to doing that in `ppHtmlIndex`. Fixes #569.
