* Add `Enum (Down a)` instance that swaps `succ` and `pred`Gergo ERDI2022-10-171-2/+22
| | | | | | | | | | | See https://github.com/haskell/core-libraries-committee/issues/51 for discussion. The key points driving the implementation are the following two ideas: * For the `Int` type, `comparing (complement @Int)` behaves exactly as an order-swapping `compare @Int`. * `enumFrom @(Down a)` can be implemented in terms of `enumFromThen @a`, if only the corner case of starting at the very end is handled specially

* Correct doctestsOleg Grenrus2021-01-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's simpler to assume that base is NoImplicitPrelude, otherwise running doctest on `GHC.*` modules would be tricky. OTOH, most `GHC.List` (where the most name clashes are) examples could be changed to use `import qualified Data.List as L`. (GHC.List examples won't show for Foldable methods...). With these changes majority of doctest examples are GHCi-"faithful", my WIP GHC-independent doctest runner reports nice summary: Examples: 582; Tried: 546; Skipped: 34; Success: 515; Errors: 33; Property Failures 2 Most error cases are *Hangs forever*. I have yet to figure out how to demonstrate that in GHCi. Some of divergences are actually stack overflows, i.e. caught by runtime. Few errorful cases are examples of infinite output, e.g. >>> cycle [42] [42,42,42,42,42,42,42,42,42,42... while correct, they confuse doctest. Another erroneous cases are where expected output has line comment, like >>> fmap show (Just 1) -- (a -> b) -> f a -> f b Just "1" -- (Int -> String) -> Maybe Int -> Maybe String I think I just have to teach doctest to strip comments from expected output. This is a first patch in a series. There is plenty of stuff already.

* Make Semigroup a superclass of Monoid (re #14191)Herbert Valerio Riedel2017-09-071-0/+1
| | | | | | | | | | | | | | | | | | | Unfortunately, this requires introducing a couple of .hs-boot files to break up import cycles (mostly to provide class & typenames in order to be able to write type signatures). This does not yet re-export `(<>)` from Prelude (while the class-name `Semigroup` is reexported); that will happen in a future commit.

* Add Haddock `/Since: 4.6.0.0/` comments to symbolsHerbert Valerio Riedel2013-09-211-0/+2
| | | | | | | | | | This commit retroactively adds `/Since: 4.6.0.0/` annotations to symbols newly added/exposed in `base-4.6.0.0` (as shipped with GHC 7.6.1). See also 6368362f which adds the respective annotation for symbols newly added in `base-4.7.0.0` (that goes together with GHC 7.8.1). Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>
* Constant-fold `__GLASGOW_HASKELL__` CPP conditionalsHerbert Valerio Riedel2013-09-171-3/+1
| | | | | | | | | | Now that HUGS and NHC specific code has been removed, this commit "folds" the now redundant `#if((n)def)`s containing `__GLASGOW_HASKELL__`. This renders `base` officially GHC only. This commit also removes redundant `{-# LANGUAGE CPP #-}`. Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>

| | | | | | | | | | Add explicit {-# LANGUAGE xxx #-} pragmas to each module, that say what extensions that module uses. This makes it clearer where different extensions are used in the (large, variagated) base package. Now base.cabal doesn't need any extensions field Thanks to Bas van Dijk for doing all the work.

Add Data.Ord and Data.Eq. Data.Ord also exports the new function 'comparing', as discussed on the libraries list a while back.
