Language tooling

[donni-h]

Hey there!
I'd love if you could cover how to set up an IDE after a fresh installation of NixOS and then maybe show how to get started with some languages' toolkit in a nix-y way (cargo/maven/npm/go/anything you can think of). As I'm new to nix and am somewhat lost as to how to get into the development workflow as it's meant to be :)

Glad to hear this is being picked up!

A few dev-tools I find occasionally useful:

• https://github.com/martinvonz/jj better git interface, especially for rebasing
• https://github.com/viperML/nh general nix helper unifiing a lot of tools
• https://github.com/Gabriella439/nix-diff derivation diffing
• https://github.com/nix-community/nix-init initialize a package structure from a project url

We decided to focus on this topic again for this weeks Nix Hour, this Thursday at 16:00 CEST! Let's talk about Nix tooling in general. If anybody has any extra questions about this topic, either:

I was so frustrated recently when I tried to get https://github.com/nix-community/gomod2nix working to deploy and run some go applications on NixOS (that are not ready for nixpkgs - yet). It feels like way too much work. I must be missing something.

In general it would be nice if there was a recommended boilerplate for getting the usual projects (go, rust, zig, ...) to port them easily to NixOS. Is there? I haven't found them.

As for general tooling: The whole toolchain is so convoluted that I have to keep notes. Just thinking of nix build vs nix-build and how I forgot the difference again.

Yarn2nix is also not well documented.
For example: signal-desktop is using the deb package instead of building from source.
While their repository has a yarn.lock, trying to build it:

{mkYarnPackage, fetchFromGitHub}:

mkYarnPackage rec {
    pname = "signalapp";
    version = "7.12.0";

    src = fetchFromGitHub {
        owner = "signalapp";
        repo = "Signal-Desktop";
        rev = "ccad9a8f0137941f6f69eadc02e0fe718709a503";
        hash = "sha256-FRVlOxqnvYl5cujio9WOD9Vs6XiLBn3KGNWRNy5vSaQ=";
        fetchSubmodules = true;
    };
}

results in an error that should? have be solved if I understand correctly.
And if we look at the lock file, those packages that yarn2nix can't find are indeed empty packages put there by the signal team.

Adding fetchYarnDeps

    offlineCache = fetchYarnDeps {
        yarnLock = src + "/yarn.lock";
        hash = "sha256-1ILcQKlHSC62HNkOj9IOhGwkjpMqrReEoiJWkanej60=";
  };

doesn't help and adding

    buildPhase = ''
    export HOME=$(mktemp -d)
    yarn build
  '';

with --offline flag removed doesn't change the This is usually caused by a missing entry in the lockfile, running Yarn without the --offline flag may help fix this issue. output either...
