base System.Exit, protolude Protolude, base-prelude BasePrelude, Cabal-syntax Distribution.Compat.Prelude, foundation Foundation.IO.Terminal, ghc-internal GHC.Internal.System.Exit, rebase Rebase.Prelude, cabal-install-solver Distribution.Solver.Compat.Prelude

The computation exitFailure is equivalent to exitWith (ExitFailure exitfail), where exitfail is implementation-dependent.

exitFailure :: MonadIO m => m a

relude Relude.Lifted.Exit

Lifted version of exitFailure.

ExitFailure :: Int -> ExitCode

indicates program failure with an exit code. The exact interpretation of the code is operating-system dependent. In particular, some values may be prohibited (e.g. 0 on a POSIX-compliant system).

exitFailureMsg :: Exit f => String -> f a

shell-utility Shell.Utility.Exit

Also known as die in newer versions of base.

pattern ExitFailure_ :: AsExitCode s => Int -> s

lens System.Exit.Lens

_ExitFailure :: AsExitCode t => Prism' t Int

lens System.Exit.Lens

indicates program failure with an exit code. The exact interpretation of the code is operating-system dependent. In particular, some values may be prohibited (e.g. 0 on a POSIX-compliant system).

_ExitFailure :: Prism' SomeException Int

catchAndExitFailure :: forall x e m a . () => MonadIO m => ExceptT (Variant (x : e)) m a -> ExceptT (Variant e) m a

oops Control.Monad.Oops

Catch the specified exception. If that exception is caught, exit the program.

onExitFailure :: ExitCode -> b -> (Int -> b) -> b

overhang Overhang

Hang on the ExitFailure case of an ExitCode.

ShellExitFailure :: Int -> ShellException

shell-conduit Data.Conduit.Shell.Types
