The `hsq_ext` field of `HsQTvs` is now just the implicit variables
(instead of also including information about which of these variables
are dependent).
This commit shouldn't change any functionality in Haddock.

`FunTy` now has an `AnonArgFlag` that indicates whether the arrow is
a `t1 => t2` or `t1 -> t2`.

Changes in 19626218566ea709b5f6f287d3c296b0c4021de2 affected some
of the hyperlinker output. Accepted the new output (hovering over a
`..` now shows you what that wildcard binds).
Also fixed some stray deprecation warnings.

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).

We now have a top-level `tyConAppNeedsKindSig` function, which means
that we can delete lots of code in `Convert`.
|
| |
|
|
|
|
|
| |
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.

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

# 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

* Synify and render properly promoted type variables
Fixes #923.
* Accept output
|
| |
|

|
|
|

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
|
| |
|
|
| |
This will make investigation of #979 easier
|
| |
|
|
|
|
|
| |
* 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

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)`)

Correspondingly, we wrap all inline/diplay math in
<span class="mathjax"> ... the math .... </span>

* Fix misplaced Haddocks in Haddock itself
Haddock should be able to generate documentation for 'haddock-api'
again.
* Make CI check that documentation can be built.
* Add back a doc that is OK

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.

In the unfortunate event that the "Contents" summary doesn't fit
vertically (like in the "Prelude"), it will be scrollable.

* swap the minimize unicode to something more intuitive
* use new unicode expander/collapser for instance lists
* address some alignment issues in the "index" page

The current html generator of this branch wraps the package-header
caption as a div, which does not work (without style adjustments) with
the old themes. Changing it from div to span does the trick, without
needing to adjust the old stylesheets.

This supports the expected responsive menu design, where the
package name appears above the menu links.

Several things are addressed here:
- better responsive behaviour on the header
- better space usage
- consistent colors overall
- other nit PR comments

* Output pattern synonyms in Hoogle backend
We were previously weren't outputting _any_ pattern synonyms, bundled or
not. Now, we output both.

* 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

Perf only change:
* don't look up type variable names (they're never in the environment)
* use a difference list for accumulating missing names
* more efficient 'Functor'/'Applicative' instances for 'RnM'
|
| | |
| |
| |
| |
| |
| |
| | |
Perf only change:
* Add a 'SPECIALIZE' pragma to help GHC optimize a 'Data a =>' constraint
* Manually specialize the needlessly general type of 'specializeTyVarBndrs'
|
| | |
| |
| |
| |
| |
| |
| |
| |

Perf only change:
* avoid needlessly union-ing maps
* avoid synify-ing instances twice
Took this opportunity to add some docs too

This should fix #929, as well as guard against future problems of this
sort in other places. Basically replaces 'writeFile' (which selects the
users default locale) with 'writeUtf8File' (which always uses utf8).
