# millerson.name Nix Overlay
|
|
|
|
A custom Nix overlay and flake providing additional packages not found in upstream nixpkgs, built using [numtide/blueprint](https://github.com/numtide/blueprint) for streamlined flake development.
|
|
|
|
## Features
|
|
|
|
- **Custom packages** - Additional software packaged for Nix
|
|
- **Two overlay strategies** - Choose between binary-cache-friendly or dependency-sharing overlays
|
|
- **Blueprint-based** - Uses modern Nix flake patterns with `numtide/blueprint`
|
|
|
|
## Available Packages
|
|
|
|
| Package | Description | Category |
|
|
|---------|-------------|----------|
|
|
| `goose-cli` | CLI for Goose - a local, extensible, open source AI agent that automates engineering tasks | AI Coding Agents |
|
|
| `mcp-gateway` | Universal Model Context Protocol gateway that sits between AI client and MCP tools/servers | MCP Servers |
|
|
| `skillsmcp` | MCP server that exposes Agent Skills to AI agents via the Model Context Protocol | MCP Servers |
|
|
|
|
## Usage
|
|
|
|
### As a Flake
|
|
|
|
Add to your `flake.nix` inputs:
|
|
|
|
```nix
|
|
inputs.millerson-nix-overlay.url = "git+https://git.millerson.name/alex/millerson-overlay.nix.git";
|
|
```
|
|
|
|
Then use in your outputs:
|
|
|
|
```nix
|
|
outputs = { nixpkgs, millerson-nix-overlay, ... }: {
|
|
nixosConfigurations.your-host = nixpkgs.lib.nixosSystem {
|
|
system = "x86_64-linux";
|
|
modules = [
|
|
millerson-nix-overlay.nixosModules.default
|
|
# ... your other modules
|
|
];
|
|
};
|
|
};
|
|
```
|
|
|
|
### As an Overlay
|
|
|
|
#### Option 1: Default Overlay (Binary Cache Friendly)
|
|
|
|
Uses the packages built against this flake's nixpkgs revision. Binary cache hits work best when using the same nixpkgs revision.
|
|
|
|
```nix
|
|
nixpkgs.overlays = [ millerson-nix-overlay.overlays.default ];
|
|
```
|
|
|
|
#### Option 2: Shared Nixpkgs Overlay (Dependency Sharing)
|
|
|
|
Builds packages against your system's nixpkgs, sharing dependencies with the rest of your system. No second nixpkgs evaluation, but binary cache only hits when your nixpkgs revision matches ours.
|
|
|
|
```nix
|
|
nixpkgs.overlays = [ millerson-nix-overlay.overlays.shared-nixpkgs ];
|
|
```
|
|
|
|
### Installing Packages
|
|
|
|
With flakes enabled:
|
|
|
|
```bash
|
|
# Try a package
|
|
nix run git+https://git.millerson.name/alex/millerson-overlay.nix.git#goose-cli
|
|
|
|
# Install permanently
|
|
nix profile install git+https://git.millerson.name/alex/millerson-overlay.nix.git#goose-cli
|
|
```
|
|
|
|
## Development
|
|
|
|
### Prerequisites
|
|
|
|
- Nix with flakes enabled
|
|
- [treefmt-nix](https://github.com/numtide/treefmt-nix) for formatting (optional)
|
|
|
|
### Building Packages
|
|
|
|
```bash
|
|
# Build all packages for current system
|
|
nix build .#packages
|
|
|
|
# Build specific package
|
|
nix build .#goose-cli
|
|
|
|
# Enter development shell
|
|
nix develop
|
|
```
|
|
|
|

|
|
|
|
### Adding New Packages
|
|
|
|
1. Create a new directory under `packages/<package-name>/`
|
|
2. Add a `package.nix` with the package definition
|
|
3. Create a `default.nix` that imports `package.nix` with proper arguments
|
|
4. The package will be automatically picked up by blueprint
|
|
|
|
Example structure:
|
|
|
|
```
|
|
packages/my-package/
|
|
├── default.nix # Import wrapper
|
|
└── package.nix # Actual package definition
|
|
```
