Hi all, I will be at ZuriHack in a few days, and I'd like to start hacking on Cabal. I'm reading the cabal codebase description on github, and I'd like a few suggestion on how to set up the environment, so that I won't waste time setting up. I use the nix package manager for all things haskell-related, so I'm wary to just do cabal install in a sandbox, as suggested by the tutorial in the github page. Here it is my current ~/.nixpkgs/config.nix: https://gist.github.com/meditans/d66371137814d0dc3707 I stripped away most of the non necessary things. As you can see from the gist, I tried to install Cabal that as a package, but it didn't work the naive way. Is there among you anyone that develops with nix? What's your configuration? Thanks, see you friday! Carlo
