* Miscellaneous improvements to `Convert` (#1020)Alec Theriault2019-02-031-1/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Theriault2019-01-311-3/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | # 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

* Refactor names + unused functions (#982)Alec Theriault2018-12-171-15/+0
| | | | | | | This commit should not introduce any change in functionality! * consistently use `getOccString` to convert `Name`s to strings * compare names directly when possible (instead of comparing strings) * get rid of unused utility functions
* Fix warnings, accept outputAlec Theriault2018-12-121-2/+0
| | | | | | | * remove redundant imports (only brought to light due to recent work for improving redundant import detection) * fix a bug that was casuing exports to appear in reverse order * fix something in haddock-library that prevented compilation on old GHC's
* [TTG: Handling Source Locations] Foundation and PatShayan-Najd2018-11-231-3/+3
| | | | | | | | | | | 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)`)
* Refactor handling of parens in types (#874)Alec Theriault2018-07-201-0/+96
| | | | | | | | | | | | | | | | | | | | | | | | * Fix type parenthesization in Hoogle backend Ported the logic in the HTML and LaTeX backends for adding in parens into something top-level in 'GhcUtil'. Calling that from the Hoogle backend fixes #873. * Remove parenthesizing logic from LaTeX and XHTML backends Now, the only times that parenthesis in types are added in any backend is through the explicit 'HsParTy' constructor. Precedence is also represented as its own datatype. * List out cases explicitly vs. catch-all * Fix printing of parens for QuantifiedConstraints The priority of printing 'forall' types was just one too high. Fixes #877. * Accept HTML output for quantified contexts test

* Fix fallout from wildcards refactoringBen Gamari2015-12-161-4/+14
| | | | | | | | | | | The wildcard refactoring was introduced a new type of signature, `ClassOpSig`, which is carried by typeclasses. The original patch adapting Haddock for this change missed a few places where this constructor needed to be handled, resulting in no class methods in documentation produced by Haddock. Additionally, this moves and renames the `isVanillaLSig` helper from GHC's HsBinds module into GhcUtils, since it is only used by Haddock.
