This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Nix flake providing custom packages not available in nixpkgs. Tracks nixos-unstable. Uses config.allowUnfree = true.

Build Commands

# Build a specific package
nix build .#packages.x86_64-linux.<package-name>

# Build all packages (x86_64-linux)
./scripts/build-all.sh

# Validate flake
nix flake check

# Update flake inputs
nix flake update

Structure

• flake.nix — Defines all packages and per-package overlays. Packages are registered in packages and exposed via overlays.
• pkgs/<name>/default.nix — Individual package definitions, called via pkgs.callPackage (or pkgs.qt6Packages.callPackage for Qt packages).
• scripts/ — Helper scripts (build-all.sh, update-pob.sh).

Adding a New Package

1. Create pkgs/<name>/default.nix with the package derivation.
2. Add the package to packages in flake.nix via callPackage.
3. Add a per-package overlay in flake.nix overlays and include it in the default overlay if appropriate.

Packaging Patterns Used

• AppImage: appimageTools.wrapType2 (see poe-sidekick)
• Electron/Yarn: yarnConfigHook + yarnBuildHook + fetchYarnDeps (see awakened-poe-trade)
• Qt6/Meson: qt6Packages.callPackage + wrapQtAppsHook (see path-of-building-*)
• Rust/Cargo: rustPlatform.buildRustPackage + useFetchCargoVendor (see noita-entangled-worlds)
• Binary/.NET: fetchurl + makeWrapper with makeLibraryPath (see vintagestory)

Commit Style

Imperative, prefixed with package name when relevant: poe-sidekick: add package, Bump entangled worlds.
