| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix multiple typos and inconsistencies in doc/markup.rst Note: I noticed some overlap with #1112 from @wygulmage and #1081 from @parsonsmatt after creating these proposed changes - mea culpa for not looking at the open PRs sooner. * Fix #1113 If no Signatures, no section of index.html * Change the formatting of missing link destinations The current formatting of the missing link destination does not really help user to understand the reasons of the missing link. To address this, I've changed the formatting in two ways: - the missing link symbol name is now fully qualified. This way you immediately know which haskell module cannot be linked. It is then easier to understand why this module does not have documentation (hidden module or broken documentation). - one line per missing link, that's more readable now that symbol name can be longer due to qualification. For example, before haddock was listing missing symbol such as: ``` could not find link destinations for: Word8 Word16 mapMaybe ``` Now it is listed as: ``` could not find link destinations for: - Data.Word.Word8 - Data.Word.Word16 - Data.Maybe.mapMaybe ``` * Add `--ignore-link-symbol` command line argument This argument can be used multiples time. A missing link to a symbol listed by `--ignore-link-symbol` won't trigger "missing link" warning. * Forbid spaces in anchors (#1148) * Improve error messages with context information (#1060) Co-authored-by: Matt Audesse <matt@mattaudesse.com> Co-authored-by: Mike Pilgrem <mpilgrem@users.noreply.github.com> Co-authored-by: Guillaume Bouchard <guillaume.bouchard@tweag.io> Co-authored-by: Pepe Iborra <pepeiborra@gmail.com>
* Add support for custom section anchors (#1179)Iñaki2020-04-251-1/+7
| | | | | | | | | | | | This allows to have stable anchors for groups, even if the set of groups in the documentation is altered. The syntax for setting the anchor of a group is -- * Group name #desiredAnchor# Which will produce an html anchor of the form '#g:desiredAnchor' Co-authored-by: Iñaki García Etxebarria <git@inaki.blueleaf.cc>
* Disallow links in section headersAlec Theriault2020-03-281-1/+1
| | | | | | | | | | | | | This is quite straightforward to implement, since we already had a function `docToHtmlNoAnchors` (which we used to generate the link in the sidebar "Contents"). This breaks test `Bug387`, but that test case has aged badly: we now automatically generate anchors for all headings, so manually adding an anchor in a section makes no sense. Nested anchors are, as pointed out in #1054, disallowed by the HTML standard. Fixes #1054
* Use `unLoc`/`noLoc` from GHC instead of `unL`/`reL`Alec Theriault2020-03-283-15/+15
| | | | | | | | * `unL` is already defined by GHC as `unLoc` * `reL` is already defined by GHC as `noLoc` (in a safer way too!) * Condense `setOutputDir` and add a about exporting from GHC Fixes #978
* Use TTG empty extensions to remove some `error`'sAlec Theriault2020-03-282-3/+5
| | | | | | | | | | | None of these error cases should ever have been reachable, so this is just a matter of leveraging the type system to assert this. * Use the `NoExtCon` and `noExtCon` to handle case matches for no extension constructors, instead of throwing an `error`. * Use the extension field of `HsSpliceTy` to ensure that this variant of `HsType` cannot exist in an `HsType DocNameI`.
* Remove unused `Haddock.Utils` functionsAlec Theriault2020-03-281-0/+4

| * 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 Theriault2019-03-093-51/+99
| | | | | | | | | | | | | | | | | | | | * 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 Theriault2019-01-232-3/+3
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * '(<|>)' 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 Theriault2019-02-032-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Theriault2019-01-316-556/+532
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | # 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
