nix-overlay — tech stack

  • Language: Nix. Build system: Nix flake via numtide/blueprint (with flake-parts, systems for multi-system).
  • Formatting: treefmt-nix → nixfmt on *.nix (flake.lock excluded in treefmt.toml).
  • Multi-input nixpkgs setup (flake.nix) — pins matter, do not "unify" them:
    • nixpkgs = nixos-unstable (default; blueprint follows it).
    • nixpkgs-latest = nixos-unstable — needed by packages requiring newer toolchains: rustc >= 1.95 (mcp-gateway >= 3.4.0), go >= 1.26.3 (kubernetes-mcp-server >= 0.0.66).
    • nixpkgs-torch211 = pinned rev 549bd84d6279f9852cae6225e372cc67fb91a4c1 — freetoken pins torch>=2.11,<2.12 / triton==3.6.0; nixos-unstable ships torch 2.13/triton 3.7, so freetoken builds via inputs.nixpkgs-torch211.legacyPackages.${system}.callPackage (see packages/freetoken/default.nix).
    • bun2nix pinned to branch staging-2.1.0 until catalog support (bun2nix#86) lands on default branch (TODO #4001).
  • Package kinds in packages/: mostly Rust (rustPlatform.buildRustPackage), Go, Python/torch, Node/bun; each self-contained in its own dir.
  • flake.lock managed only via nix flake update — never hand-edited.
