Haskell-mode integrations for Nix
Setup for this is fairly straightforward. It aims to automatically configure everything for you. It assumes that you are already using haskell-mode and flycheck. If you have use-package setup, this is enough to get nix-haskell working, (use-package nix-haskell :hook (haskell-mode . nix-haskell-mode)) Opening a buffer will start a nix process to get your dependencies. Flycheck and interactive-haskell-mode will start running once they have been downloaded. This is cached so it will only be done once for each buffer. Flycheck will be started automatically. To start a haskell session, press C-c C-l. nix-haskell is designed to build package dbs in Nix and then pass them to GHC. This should avoid some of the security issues in using ‘nix-shell’ automatically in visited directories.
