1. readerTRuntime :: (FromJSON event, ToJSON result) => (event -> ReaderT LambdaContext IO result) -> IO ()

   hal	AWS.Lambda.Runtime

   For functions that can read the lambda context and use IO within the same monad. Use this for handlers that need any form of side-effect such as reading environment variables or making network requests, and prefer to access the AWS Lambda Context in the same monad. However, do not use this runtime if you need stateful (caching) behaviors.

8. readProcessWithCwd :: LogAction IO (WithSeverity Log) -> FilePath -> FilePath -> [String] -> String -> IO (CradleLoadResult String)

   hie-bios	HIE.Bios.Cradle

   Wrapper around readCreateProcess that sets the working directory and clears the environment, suitable for invoking cabal/stack and raw ghc commands.

9. readProcessWithOutputs :: Outputs -> LogAction IO (WithSeverity Log) -> FilePath -> CreateProcess -> IO (ExitCode, [String], [String], [(OutputName, Maybe [String])])

   hie-bios	HIE.Bios.Cradle

   Call a given process with temp files for the process to write to. * The process can discover the temp files paths by reading the environment. * The contents of the temp files are returned by this function, if any. * The logging function is called every time the process emits anything to stdout or stderr. it can be used to report progress of the process to a user. * The process is executed in the given directory.

10. readProcessWithCwd :: LogAction IO (WithSeverity Log) -> FilePath -> FilePath -> [String] -> String -> IO (CradleLoadResult String)

    hie-bios	HIE.Bios.Process

    Wrapper around readCreateProcess that sets the working directory and clears the environment, suitable for invoking cabal/stack and raw ghc commands.
