Detect Either Windows or Linux environment
Is there a simple way to detect what operating system a given Haskell program is running under? It would help to make some programs that might have to interact with the operating system more portable. I haven't been able to quite figure out a simple way to do this. -- View this message in context: http://www.nabble.com/Detect-Either-Windows-or-Linux-environment-tf3695277.h...

Thank you for your help. I somehow missed that when I was browsing through the library documentation. On windows, interestingly the os function returns "mingw" -- View this message in context: http://www.nabble.com/Detect-Either-Windows-or-Linux-environment-tf3695277.h...

Yes, that's one of Neil's pet hates. It might change so something more obvious some time. Duncan
Hi

On Yhc the os function will return the name of the OS, on GHC and Hugs it returns mingw even if you are using the native WinHugs build done using Visual Studio and have never installed mingw... And its still one of my pet hates! Thanks Neil

Presumably GHC is compiled under mingw. (Personally I'm not a fan of having to use a UNIX emulator when you're actually in M$ Windoze, but never mind...)
