macOS

services-flake provides declarative, composable, and reproducible services for Nix development environment, and is based on flake-parts. Enabling users to have NixOS-like service on macOS and Linux.

nix-darwin brings NixOS like configuration to macOS, allowing you to install packages (among doing other things) purely through Nix.

[!note] macOS support While macOS doesn’t enjoy first-class support in nixpkgs yet, improvements are underway.

[!note] macOS caveat If you are on macOS, the Haskell package will not run because dlopen will be looking for the .dylib file in the temporary build directory (/private/tmp/nix-build-rust-nix...). To fix this, you need to include fixDarwinDylibNames in flake.nix:

Upgrading macOS is known to break Nix. When this happens, just uninstall Nix and then install it again.

[!tip] Verify on macOS To confirm that the font was successfully installed on macOS, you can open the “Font Book” app and search for the font. They will have been installed into $HOME/Library/Fonts/HomeManager folder.

Whethere you are on macOS or NixOS, you can install and setup fonts in an unified fashion with Nix using home-manager.

[!info] Linux If you prefer to use Linux, you may be interested in installing NixOS. The following instructions are for users of other Linux distros as well as macOS.

Sridhar Ratnakumar will demonstrate the delights of using Nix to develop Rust as well as Haskell projects without needing to do any manual global setup on your system. We’ll start from a pristine macOS machine as well as a pristine Linux machine to get our development environment up and running in no time, all the way up to LSP support in VSCode.
