# 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.
