digga VS nixos-config

This one issue may clear things up, seems like my config is a little outdated: https://github.com/divnix/digga/pull/385

I'm new to the Nix world, but so far I've come across Divnix's Digga, Numtide's DevShell, and Misterio77's nix-starter-configs.

There are config templates / configuration helper libraries that try to make this easier, for example digga/devos.

https://nixos.wiki/wiki/Flakes, especially the “see also” section. If you’re looking to use for NixOS config across multiple hosts, digga (see the repo for example template) is pretty nice for encapsulating a lot of boilerplate.

The digga library, while being more complex to use than other solutions here, got a pretty elegant solution for it merged a few weeks ago. Still some cracks that are getting smoothed over, but it seems to work.

I like the concept digga/devos uses (unfortunately their stuff kind of is an overengineered incomprehensible mess): They use: - modules: for modules like in nixpkgs (i.e. stuff that defines options and generates configuration based on that options; are included into every host) - profiles: concrete configuration, can be included to host definitions - suites: sets of profiles (so you can for example have a desktop suite with all your profiles with "desktop" configuration options and apply that to all your desktop computers)

For the system, I like the devos template:

https://github.com/divnix/devos

The idea of flakes is how you define inputs, and you define the system (and packages, and shell etc.) in the outputs using the inputs. The inputs are git repos which point to other flakes. You can mix and match these as much as you want (see the devos repo for examples) and when you build the derivation, it generates a lockfile for exact commits in that point in time what were used in the given inputs.

You commit the lockfile and in the other systems where you pull your config from the repo, it uses exactly those commits and installs the same versions as you did in your other systems.

This was quite annoying and hard to do before flakes. Now it's easy.

The problem what people face with building their system as a flake is combining the packages so you can point to `jq` from the unstable nixos and firefox from the stable train. I think this aspect needs better documentation so it wouldn't be so damn hard to learn (believe me, I know). Luckily there are projects like devos that give a nice template for people to play with (with documentation!)

Another use for flakes is to create a development shell for your repo, an example what I did a while ago:

https://github.com/pimeys/nix-prisma-example

Either have `nix-direnv` installed, enter the directory and say `direnv allow`, or just `nix develop` and it will gather, compile and install the correct versions of packages to your shell. Updating the packages? Call `nix flake update` in the directory, commit the lockfile and everybody else gets the new versions to their shell.

Yes, I put the repository in ~/nix. My repository is based on devos, but I am thinking of switching to a different setup, because I don't want to depend on a framework which can be an issue in updating.

I no longer use the official way since I have switched to flakes. I am currently using a devos-based config, which is a boilerplate that depends on a Nix toolchain, but I plan on rewriting the config with flake-utils-plus. You probably can install home-manager using deploy-rs. See the following comment:

Here’s Mitchell Hashimoto (founder of HashiCorp) setup config.

In my case, I started by installing the NixOS using the Gnome Installer on VmWare fusion, and then modified it using the example config from mitchellh as a guide. Actually entering the configuration yourself definitely helps with learning.

I have a NixOS dev environment in a VM which I built based on https://github.com/mitchellh/nixos-config. Similar to that setup, I use Flakes for my main configuration, and use home-manager to install + configure dev tools that I want available across multiple projects

Yes, maybe not as easily. Check my setup https://github.com/kohlerm/nixos-config which I forked from https://github.com/mitchellh/nixos-config a while ago

Hi, if u can not get a linux pc - then have a look on the following thing (nixos). https://github.com/mitchellh/nixos-config

I'm developing mostly using console applications like vim so I don't need GUI apps for what I'm doing and this made me wonder if it's not better to simply spin a Linux VM inside my macOS to do my development. Something like this: https://github.com/mitchellh/nixos-config (this guy is one of the founders of Hashicorp)

One of the most popular NixOS configs on GitHub does this https://github.com/mitchellh/nixos-config

The README describes the experience, though the author takes the approach of using the VM mainly for terminal-based stuff.
