* Fix build-failure regression for base < 4.7Herbert Valerio Riedel2019-12-086-30/+61
| | | | | | | | | | | | | The `$>` operator definition is available only since base-4.7 which unfortunately wasn't caught before release to Hackage (but has been fixed up by a metadata-revision) This commit introduces a `CompatPrelude` module which allows to reduce the amount of CPP by ousting it to a central location, i.e. the new `CompatPrelude` module. This pattern also tends to reduce the tricks needed to silence unused import warnings. Addresses #1119
* Document error-prone conditional definition of instancesHerbert Valerio Riedel2019-12-081-0/+6
| | | | | | | | | This can easily trip up people if one isn't aware of it. Usually it's better to avoid this kind of conditionality especially for typeclasses for which there's an compat-package as conditional instances like these tend to fragment the ecosystem into those packages that go the extra mile to provide backward compat via those compat-packages and those that fail to do so.
* Changes from #14579Ryan Scott2019-11-031-22/+5
| | | | | | | We now have a top-level `tyConAppNeedsKindSig` function, which means that we can delete lots of code in `Convert`. (cherry picked from commit cfd682c5fd03b099a3d78c44f9279faf56a0ac70)
* Reify oversaturated data family instances correctly (#1103)Ryan Scott2019-10-233-15/+603
| | | | | | This fixes #1103 by adapting the corresponding patch for GHC (see https://gitlab.haskell.org/ghc/ghc/issues/17296 and https://gitlab.haskell.org/ghc/ghc/merge_requests/1877).
* Add Hyperlinker test cases for TH-related stuffAlec Theriault2019-10-079-0/+1489
| | | | | Hopefully this will guard against regressions around quasiquotes, TH quotes, and TH splices.
* Add a regression test for #1091Alec Theriault2019-10-075-0/+49
| | | | Previously, this input would crash Haddock.
* Prefer un-hyperlinked sources to no sourcesAlec Theriault2019-10-072-14/+26
| | | | | | It is possible to fail to extract an HIE ast. This is however not a reason to produce _no_ output - we should still make a colorized HTML page.

* Fix the ignore-exports option (#1082)Alexis King2019-09-304-18/+56
| | | The `ignore-exports` option has been broken since #688, as mentioned in https://github.com/haskell/haddock/pull/766#issue-172505043. This PR fixes it.
* Fix Travis CI, loosen .cabal bounds (#1089)Alec Theriault2019-09-204-102/+135
| | | | | | | Tentatively for the 2.23 release: * updated Travis CI to work again * tweaked bounds in the `.cabal` files * adjusted `extra-source-files` to properly identify test files
* update for new way to store hiefile headersZubin Duggal2019-06-041-2/+3

* Release haddock-2.23, haddock-library-1.8.0Alec Theriault2019-05-266-17/+18
| | | | | Tentatively adjust bounds and changelogs for the release to be bundled with GHC 8.8.1.

* | Regression test: promoted lists in associated typesAlec Theriault2019-05-262-0/+257
| | | | | | | | | | | | | | | | When possible, associated types with promoted lists should use the promoted list literal syntax (instead of repeated applications of ': and '[]). This was fixed in 2122de5473fd5b434af690ff9ccb1a2e58491f8c. Closes #466,
* | Remove Haddock's dependency on `Cabal`Alec Theriault2019-05-265-12/+22
| | | | | | | | | | | | | | | | At this point, Haddock depended on Cabal-the-library solely for a verbosity parser (which misleadingly accepts all sorts of verbosity options that Haddock never uses). Now, the only dependency on Cabal is for `haddock-test` (which uses Cabal to locate the Haddock interface files of a couple boot libraries).
* | Fix #1063 with better parenthesization logic for contextsAlec Theriault2019-05-173-2/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only other change in html/hoogle/hyperlinker output for the boot libraries that this caused is a fix to some Hoogle output for implicit params. ``` $ diff -r _build/docs/ old_docs diff -r _build/docs/html/libraries/base/base.txt old_docs/html/libraries/base/base.txt 13296c13296 < assertError :: (?callStack :: CallStack) => Bool -> a -> a --- > assertError :: ?callStack :: CallStack => Bool -> a -> a ```
* | Unbreak #1004 test caseAlec Theriault2019-05-171-11/+1

* | Remove obsolete arcanist files + STYLEAlec Theriault2019-05-133-32/+0
| | | | | | | | | | Now that GHC is hosted on Gitlab, the arcanist files don't make sense anymore. The STYLE file contains nothing more than a dead link too.
* | Remove outdated `.ghci` files and `scripts`Alec Theriault2019-05-135-57/+0
| | | | | | | | | | The `.ghci` files are actively annoying when trying to `cabal v2-repl`. As for the `scripts`, the distribution workflow is completely different.

* | Remove workaround for now-fixed Clang CPP bug (#1028)Alec Theriault2019-03-296-110/+22
| | | | | | | | | | | | | | | | | | | | | | 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 Theriault2019-03-0929-732/+253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Theriault2019-03-095-1/+93
| | | | | | | | | | | | | | | | `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 Theriault2019-03-0913-51/+606
| | | | | | | | | | | | | | | | | | | | * 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
* | Add .hi, .dyn_hi, etc files to .gitignoreAlec Theriault2019-03-091-0/+6

| * Increase contrast of Linuwal theme (#1037)gbaz2019-03-011-4/+6
| | | | | | | | | | | | | | | | | | | | This is to address the concern that, on less nice and older screens, some of the shades of grey blend in too easily with the white background. * darken the font slightly * darken slightly the grey behind type signatures and such * add a border and round the corners on code blocks * knock the font down by one point

| * Menu item controlling which instances are expanded/collapsed (#1007)Xia Li-yao2019-02-278-229/+635
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a menu item (like "Quick Jump") for options related to displaying instances. This provides functionality for: * expanding/collapsing all instances on the currently opened page * controlling whether instances are expanded/collapsed by default * controlling whether the state of instances should be "remembered" This new functionality is implemented in Typescript in `details-helper`. The built-in-themes style switcher also got a revamp so that all three of QuickJump, the style switcher, and instance preferences now have the same style and implementation structure. See also: https://mail.haskell.org/pipermail/haskell-cafe/2019-January/130495.html Fixes #698. Co-authored-by: Lysxia <lysxia@gmail.com> Co-authored-by: Nathan Collins <conathan@galois.com>
| * Fix standalone deriving docsAlec Theriault2019-02-253-2/+235
| | | | | | | | | | | | | | | | Docs on standalone deriving decls for classes with associated types should be associated with the class instance, not the associated type instance. Fixes #1033
| * Make a fixture of weird parsing of lists (#997)Oleg Grenrus2019-02-045-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | The second example is interesting. If there's a list directly after the header, and that list has deeper structure, the parser is confused: It finds two lists: - One with the first nested element, - everything after it I'm not trying to fix this, as I'm not even sure this is a bug, and not a feature.
| * Update README instructions for StackNathan Collins2019-02-021-2/+2
| | | | | | No need to `stack install` Haddock to test it. Indeed, `stack install` changes the `haddock` on user's `PATH` if `~/.local/bin` is on user's `PATH` which may not be desirable when hacking on Haddock.
| * Loosen 'QuickCheck' and 'hspec' boundsAlec Theriault2019-01-282-5/+5
| | | | | | | | | | It looks like the new versions don't cause any breakage and loosening the bounds helps deps fit in one stack resolver.

| * Keep forall on H98 existential data constructors (#1003)Alec Theriault2019-01-234-11/+27
| | | | | | | | | | | | | | 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 Theriault2019-02-263-9/+160
| | | | | | | | | | | | | | | | 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 Theriault2019-02-2521-135/+679
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * '(<|>)' 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 Theriault2019-02-2517-39/+388
| | | | | | | | | | | | | | | | | | | | | | 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 Theriault2019-02-0311-240/+472
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
