GHCup.Prelude
Description
GHCup specific prelude. Lots of Excepts functionality.
Synopsis
- catchWarn :: forall (es :: [Type]) (m :: Type -> Type) env. (Pretty (V es), HFErrorProject (V es), MonadReader env m, HasLog env, MonadIO m, Monad m) => Excepts es m () -> Excepts ('[] :: [Type]) m ()
- runBothE' :: forall (e :: [Type]) (m :: Type -> Type) a b. (Monad m, Show (V e), Pretty (V e), HFErrorProject (V e), PopVariant InstallSetError e, LiftVariant' e (InstallSetError ': e), e :<< (InstallSetError ': e)) => Excepts e m a -> Excepts e m b -> Excepts (InstallSetError ': e) m ()
- addToPath :: [FilePath] -> Bool -> IO [(String, String)]
- addToPath' :: [(String, String)] -> [FilePath] -> Bool -> [(String, String)]
- module GHCup.Prelude.Internal
- isWindows :: Bool
- enableAnsiSupport :: IO (Either String Bool)
- isNotWindows :: Bool

runBothE' :: forall (e :: [Type]) (m :: Type -> Type) a b. (Monad m, Show (V e), Pretty (V e), HFErrorProject (V e), PopVariant InstallSetError e, LiftVariant' e (InstallSetError ': e), e :<< (InstallSetError ': e)) => Excepts e m a -> Excepts e m b -> Excepts (InstallSetError ': e) m () Source #
module GHCup.Prelude.Internal
enableAnsiSupport :: IO (Either String Bool) Source #
Enables ANSI support on windows, does nothing on unix.
Returns 'Left str' on errors and 'Right bool' on success, where
bool markes whether ansi support was already enabled.
This function never crashes.
