Hey folks - I'm gonna spend like 35min setting up Roc on a NixOS machine and trying out AoC day 1. If anyone wants to tag along - feel free to join me :)

This might be a good start https://github.com/roc-lang/roc/blob/main/BUILDING_FROM_SOURCE.md

Anton (Dec 04 2023 at 16:34):

@John Murray found a new approach you could try out:

nix-shell -p steam-run
steam-run <downloaded-roc-binary>

Anton (Dec 04 2023 at 16:35):

No need to build from source anymore :)

I also patched the binary myself for AoC: https://gitlab.com/arkandos/aoc/-/blob/2023/flake.nix?ref_type=heads
The hashes might be wrong since the last nightly update, but that's an easy fix :smile:

Some excerpts from my vscode setup from configuration.nix (for 23.05):

  (import "${home-manager}/nixos")
];

# temp workaround for https://github.com/NixOS/nixpkgs/issues/196651
manual.manpages.enable = false;

programs.vscode = {
  enable = true;

  extensions = with pkgs.vscode-extensions; [
      matklad.rust-analyzer
      eamodio.gitlens
      bbenoist.nix
      vadimcn.vscode-lldb
      tamasfe.even-better-toml
      github.vscode-github-actions
      ms-vscode.cpptools
      ms-vscode.cmake-tools
   ]
              ++ pkgs.vscode-utils.extensionsFromVscodeMarketplace [
                 {
                    name = "roc-lang-support";
                    publisher = "benjamin-thomas";
                    version = "0.0.3";
                    sha256 = "sha256-mabNegZ+XPQ6EIHFk6jz2mAPLHAU6Pm3w0SiFB7IE+s=";
                  }
                ]
              ;

  userSettings = {
    "terminal.integrated.shell.linux" = "/run/current-system/sw/bin/bash";
    "files.autoSave" = "afterDelay";
    "editor.scrollBeyondLastLine" = "false";
    "terminal.integrated.scrollback" = 20000;
    "telemetry.telemetryLevel" = "off";
    #"enable-crash-reporter" = "false";
  };

home.stateVersion = "23.05";

hitting my head against the wall in public by trying out random paths quickly :sweat_smile:

Georges Boris (Dec 04 2023 at 16:50):

decide to prep things better upfront so I can have Roc running on my NixOS (maybe after lining things up I can do it on camera just for the sake of it)

Georges Boris (Dec 04 2023 at 16:59):

managed to get everything working in 10min after not doing it in public :) (building from source was pretty straightforward on nixos tbh...)

Anton (Dec 04 2023 at 17:13):

I'm planning on adding a dedicated NixOS section to https://www.roc-lang.org/install to make things easier in the future.

John Murray (Dec 04 2023 at 18:16):

The steam run approach is great to try it out

If you want to include roc in a flake (which builds from source) i have this example https://github.com/JRMurr/AdventOfCode2023/blob/main/flake.nix

which sets up the lsp for https://github.com/ivan-demchenko/roc-vscode-unofficial via export ROC_LSP_PATH=${rocFull}/bin/roc_ls

here's a first: @Loris Cro solving Advent of Code in both Roc and Zig on stream! :smiley:

Cool :)

Hey, I'm streaming solving day 8 with Roc ^^
