Methods

throwM :: Exception e => e -> ShellT m a

(MonadUnliftIO (ShellT m), Applicative m, MonadThrow m) => Alternative (ConduitT i o (ShellT m))

Intentionally only handles ShellException. Use normal exception handling to handle usual exceptions.

many :: ConduitT i o (ShellT m) a -> ConduitT i o (ShellT m) [a]

data ShellException

An exception resulting from a shell command.

Constructors

ShellExitFailure !Int

Process exited with failure.
