nix with marimo

[dmadisetti]

marimo is packaged on nixpkgs
But maybe you have a flake or two you'd like to share?
Just a general discussion thread for marimo + nix

{
  description = "A very basic flake";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
  };

  outputs = { self, nixpkgs }: {

    devShells.x86_64-linux.default = let
      pkgs = nixpkgs.legacyPackages.x86_64-linux;
    in pkgs.mkShell {
      buildInputs = with pkgs; [
        nodejs_22
        pnpm_9
        python3
        hatch
      ];
    };

  };
}

For the unitiated: assuming you have flakes and nix-command enabled, you can run nix develop and this will install development dependencies in a "development shell" - you should be able to run make fe and make py and get a development build of marimo on your system.

It's configured for x86 linux -- swap out the system tag in the snippet above if you're on mac

I've found a very helpful Nix function to seemingly avoid most all dynamic linking issues e.g. with Pixi and uv.

If you're trying to set up a marimo dev environment you can try:

{
  inputs = {
    flake-utils.url = "github:numtide/flake-utils";
  };
  outputs =
    { nixpkgs, flake-utils, ... }:
    flake-utils.lib.eachDefaultSystem (
      system:
      let
        pkgs = import nixpkgs { inherit system; };
        fhs = pkgs.buildFHSEnv {
          name = "pixi-env";

          targetPkgs = _: with pkgs; [ pixi gcc uv ];
        };
      in
      {
        devShell = fhs.env;
      }
    );
}

All thanks to this EXTREMELY helpful article which gives tips specific to both Pixi and uv:

How to Run Non-Nix Executables

Edit: that doesnt seem to be the article i was thinking of, but I'll share if i come across it again. Leaving the article since it's still got helpful tips!

Edit2: Found it! So good! https://wiki.nixos.org/wiki/Python
