Description
Promises for processes
- processPromise :: FilePath -> [String] -> String -> IO (Promise ProcessResult)
- processPromiseCallback :: (ProcessResult -> IO ()) -> FilePath -> [String] -> String -> IO (Promise ProcessResult)
- data ProcessResult = ProcessResult {}
- data ExitCode

Arguments
| :: FilePath | Program to run |
| -> [String] | Arguments |
| -> String | Input string (stdin) |
| -> IO (Promise ProcessResult) | Promise object |
Make a Promise
Arguments
| :: (ProcessResult -> IO ()) | Callback |
| -> FilePath | Program to run |
| -> [String] | Arguments |
| -> String | Input string (stdin) |
| -> IO (Promise ProcessResult) | Promise object |
Make a Promise, but add a callback that will
be run when the process finishes nicely.
This hook is mainly intended for logging.
data ExitCode
Defines the exit codes that a program can return.
Constructors
| ExitSuccess | indicates successful termination; |
| ExitFailure Int | 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). |
