* 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 Theriault2019-01-3112-663/+727
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | # 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)`)

| | * Avoid some partialityAlec Theriault2018-10-263-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Support for type families in LaTeX The code is ported over from the XHTML backend. * Refactor XHTML and LaTeX family handling This is mostly a consolidation effort: stripping extra exports, inlining some short definitions, and trying to make the backends match. The LaTeX backend now has preliminary support for data families, although the only the data instance head is printed (not the actual constructors). Both backends also now use "newtype" for newtype data family instances. * Add some tests

| | * Fix broken instance source links (#869)Alec Theriault2018-07-202-19/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | The problem manifests itself in instances that are defined in modules other than the module where the class is defined. The fix is just to thread through the 'Module' of the instance further along. Since orphan instances appear to already have been working, I didn't do anything there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'spanToNewline' is used to help break apart the source into lines which can then be partioned into CPP and non-CPP chunks. It is important that 'spanToNewline' not break apart tokens, so it needs to properly handle things like * block comments, possibly nested * string literals, possibly multi-line * CPP macros, possibly multi-line String literals in particular were not being properly handled. The fix is to to fall back in 'Text.Read.lex' to help lex things that are not comments. Fixes #837.
