  1. formatCalendarTime :: TimeLocale -> String -> CalendarTime -> String

    old-time System.Time

    formats calendar times using local conventions and a formatting string. The formatting string is that understood by the ISO C strftime() function.

  2. formatTimeDiff :: TimeLocale -> String -> TimeDiff -> String

    old-time System.Time

    formats time differences using local conventions and a formatting string. The formatting string is that understood by the ISO C strftime() function.

  3. forgivingAbsence :: (MonadIO m, MonadCatch m) => m a -> m (Maybe a)

    path-io Path.IO

    If argument of the function throws a doesNotExistErrorType, Nothing is returned (other exceptions propagate). Otherwise the result is returned inside a Just.

  4. forkPingThread :: Connection -> Int -> IO ()

    websockets Network.WebSockets

    Deprecated: Use withPingThread instead

  5. forkPingThread :: Connection -> Int -> IO ()

    websockets Network.WebSockets.Connection

    Deprecated: Use withPingThread instead

  6. forAll :: forall (m :: Type -> Type) a . Testable m a => a -> Property m

    tasty-smallcheck Test.Tasty.SmallCheck

    Set the universal quantification context.

  7. foreignName :: Foreign -> Name

    haskell-src-meta Language.Haskell.Meta.Utils

    No documentation available.

  8. forwardSub :: (Num a, Fractional a, Foldable m, Additive m, Ixed (m a), Ixed (m (m a)), i ~ Index (m a), i ~ Index (m (m a)), Eq i, Ord i, Integral i, a ~ IxValue (m a), m a ~ IxValue (m (m a))) => m (m a) -> m a -> m a

    linear Linear.Matrix

    Solve a linear system with a lower-triangular matrix of coefficients with forwards substitution.

  9. forwardSubFinite :: forall a m (n :: Nat) . (Num a, Fractional a, Foldable m, n ~ Size m, KnownNat n, Additive m, Finite m) => m (m a) -> m a -> m a

    linear Linear.Matrix

    Solve a linear system with a lower-triangular matrix of coefficients with forwards substitution, using the vector's Finite instance to provide an index.

  10. forOf_ :: forall k f (is :: IxList) s a r . (Is k A_Fold, Applicative f) => Optic' k is s a -> s -> (a -> f r) -> f ()

    optics-core Optics.Fold

    A version of traverseOf_ with the arguments flipped.
