[Haskell-beginners] Re: Capture stdout from a command on Windows

Under Unix I use readProcess or readProcessWithExitCode from System.Process to get the output without fiddling with handles. HTH Christian Am 15.09.2010 20:08, schrieb David Frey:

Hi,

I'm trying to capture the output (stdout) of a command on Windows.

This is what I have so far:

import System.Process (runProcess, waitForProcess) import System.IO (hGetContents)

executeCapturingStdout :: String -> String -> IO [String] executeCapturingStdout cmd workingDir = do let stdoutHandle = -- TODO: What do I put here? processHandle <- runProcess cmd [] (Just workingDir) Nothing Nothing stdoutHandle Nothing exitCode <- waitForProcess processHandle content <- hGetContents stdoutHandle return lines content

I have tried searching on google and I haven't been able to find an answer yet.

Thanks, Dave
