map :: (a -> b) -> [a] -> [b]
map f xs is the list obtained by applying f to each element
of xs, i.e.,
map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn] map f [x1, x2, ...] == [f x1, f x2, ...]
class IsString a where
Class for string-like datastructures; used by the overloaded string extension (-foverloaded-strings in GHC).
Methods
fromString :: String -> a
Arguments
| :: FilePath | Filename of the executable (see |
| -> [String] | Arguments to pass to the executable |
| -> Maybe FilePath | Optional path to the working directory |
| -> Maybe [(String, String)] | Optional environment (otherwise inherit) |
| -> IO (Handle, Handle, Handle, ProcessHandle) |
Runs a raw command, and returns Handles that may be used to communicate
with the process via its stdin, stdout and stderr respectively.
For example, to start a process and feed a string to its stdin:
(inp,out,err,pid) <- runInteractiveProcess "..." forkIO (hPutStr inp str)
The Handles are initially in binary mode; if you need them to be
in text mode then use hSetBinaryMode.
