uld possibly run in parallel. To have useful composition operators, wouldn't you need more precise types for your IO actions? Regards, Rickard ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

Re: [Nix-dev] "IO" in Nix

Not to turn this into a flame war, but there were discussions in the past whether Nix should have been a DSL embedded in, say, Haskell. IIRC, you felt okay about it being a standalone DSL, do you still feel the same way? P.S. Yes, I know about Guix, but it's written in (a uni-typed) Scheme.

Re: [Nix-dev] "IO" in Nix

Hey Dan, This sounds a lot like the motivation and design for nix-exec, have you looked into whether it might work for you as-is or with something built on top of it? I'd be happy to chat about this too if you want to go over in more detail. ~Shea Daniel Peebles writes:

[Nix-dev] "IO" in Nix

Hi all, I've been experimenting with a pattern recently that I'd say is fairly close to a Haskell notion of IO. I have a collection of Nix-centered scripts that need to perform fairly restricted side effects: - Build an AMI (image) for AWS - Write some disk image stuff to a raw device -
