Correct me if I'm wrong, but if I want to make this work on windows I can't use System.Posix, right? If so, what is the portable way to set environment variables? I see[1] that getEnv exists in System.Environment, but setEnv is in System.Posix.Env. I looked in System.Win32 and I didn't see anything that looked like it would manipulate environment variables. Will I have to use System.Process.runProcess on Win32? I'd like this to work on ghc 6.6 and System.Process looks new?
Right. Typically you do not need to change the env vars for your own process, just to pass new ones to new processes and System.Process.runProcess lets you specify a new set of environment vars.
Thanks. I just tried this out and it should do what I want. I see that I just fetch the current environment, append or update it and then pass it to runProcess.
As you can check, System.Process.runProcess has been around since ghc 6.6 (and before):
Thanks, it's really nice to have that unambiguously be in 6.6. Jason
