* 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 Theriault2019-03-091-23/+24
| | | | | | | | | | * 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

| * Keep forall on H98 existential data constructors (#1003)Alec Theriault2019-01-231-1/+1
| | | | | | | | | | | | | | 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.
| * More uniform handling of `forall`'s in HTML/LaTeXAlec Theriault2018-11-261-21/+28
| | | | | | | | | | | | | | * don't forget to print explicit `forall`'s when there are arg docs * when printing an explicit `forall`, print all tyvars Fixes #973
* | Better identifier parsingAlec Theriault2019-02-251-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * '(<|>)' 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).
* | Miscellaneous improvements to `Convert` (#1020)Alec Theriault2019-02-031-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* | Refactor names + unused functions (#982)Alec Theriault2018-12-171-9/+6
| | | | | | | | | | | | | | 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
* | [TTG: Handling Source Locations] Foundation and PatShayan-Najd2018-11-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | 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)`)

| * Latex type families (#734)Alec Theriault2018-10-161-24/+107

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
| * Update the ghc-8.6 branch (#889)Simon Jakobi2018-07-201-76/+47

The next version bump to `ghc-head` is supposed to go from e.g. 8.5 to 8.7 This reverts commit 5e3cf5d8868323079ff5494a8225b0467404a5d1. * README updates (#856) * README: Remove mentions of master branch * README: Add instructions for using html-test * README: Change command to run _all_ the testsuites * README: Add project overview section (cherry picked from commit 61d6f935da97eb96685f07bf385102c2dbc2a33c) * Export more fixities for Hoogle (#871) This exports fixities for more things, including class methods and type-level operators. (cherry picked from commit 88316b972e3d47197b1019111bae0f7f87275fce) * Avoid line breaks due to line length in Hoogle (#868) * Avoid line breaks due to line length in Hoogle Hoogle operates in a line-oriented fashion, so we should avoid ever breaking due to long lines. One way of doing this non-intrusively is to modify the 'DynFlags' that are threaded through the 'Hoogle' module (note this is anyways only passed through for use in the various 'showSDoc' functions). * Amend test case (cherry picked from commit 657b1b3d519545f8d4ca048c06210d6cbf0f0da0) * tyThingToLHsDecl: Preserve type synonyms that contain a forall (#880) * tyThingToLHsDecls: Preserve type synonyms that contain a forall Fixes #879. * Add Note [Invariant: Never expand type synonyms] * Clarify Note [Invariant: Never expand type synonyms] (cherry picked from commit c3eb3f0581f69e816f9453b1747a9f2a3ba02bb9) * Fix HEAD html-test (#860) * Update tests for 'StarIsType' * Accept tests * Revert "Update tests for 'StarIsType'" This reverts commit 7f0c01383bbba6dc5af554ee82988d2cf44e407a. * Refactor handling of parens in types (#874) * 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 * Preserve docs on type family instances (#867) * Preserve docs on type family instances The only problem was that the instance location was slightly off for type family instances. * Accept output (cherry picked from commit 133e9c2c168db19c1135479f7ab144c4e33af2a4) * Fix broken instance source links (#869) 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. (cherry picked from commit 2de7c2acf9b1ec85b09027a8bb58bf8512e91c05) * Add some more unicode related tests (#872) This has been fixed for sure ever since we switched from attoparsec to parsec. Parts of it may have been working before that, but there was a point where this would have failed (see #191). A regression test never hurt anyone. :) (cherry picked from commit 5ec7715d418bfac0f26aec6039792a99a6e89370) * Misc tests (#858) * More tests * spliced types * constructor/pattern argument docs * strictness marks on fields with argument docs * latex test cases need seperate directory * Accept tests * Additional tests for the identifier parser (#816) * Add tests for the identifier parser * docs: Clarify how to delimit identifiers (cherry picked from commit 0861affeca4d72938f05a2eceddfae2c19199071)

Adds support for rendering Haddock's on (non-record) constructor arguments, both for regular and GADT constructors. * Support haddocks on pattern synonym arguments It appears that GHC already parsed these - we just weren't using them. In the process of doing this, I tried to deduplicate some code around handling patterns. * Update the markup guide Add some information about the new support for commenting constructor arguments, and mention pattern synonyms and GADT-style constructors. * Overhaul LaTeX support for data/pattern decls This includes at least * fixing several bugs that resulted in invalid LaTeX * fixing GADT data declaration headers * overhaul handling of record fields * overhaul handling of GADT constructors * overhaul handling of bundled patterns * add support for constructor argument docs * Support GADT record constructors This means changes what existing HTML docs look like. As for LaTeX, looks like GADT records were never even supported. Now they are. * Clean up code/comments Made code/comments consistent between the LaTeX and XHTML backend when possible. * Update changelog * Patch post-rebase regressions * Another post-rebase change We want return values to be documentable on record GADT constructors.
