'nix dev-shell' is intended to replace nix-shell. It supports flakes, e.g. $ nix dev-shell nixpkgs:hello starts a bash shell providing an environment for building 'hello'. Like Lorri (and unlike nix-shell), it computes the build environment by building a modified top-level derivation that writes the environment after running $stdenv/setup to $out and exits. This provides some caching, so it's faster than nix-shell in some cases (especially for packages with lots of dependencies, where the setup script takes a long time). There also is a command 'nix print-dev-env' that prints out shell code for setting up the build environment in an existing shell, e.g. $ . <(nix print-dev-env nixpkgs:hello) https://github.com/tweag/nix/issues/21
Nix, the purely functional package manager
Nix is a new take on package management that is fairly unique. Because of its purity aspects, a lot of issues found in traditional package managers don't appear with Nix.
To find out more about the tool, usage and installation instructions, please read the manual, which is available on the Nix website at http://nixos.org/nix/manual.
