# m3ta-nixpkgs Documentation

Complete documentation for m3ta's personal Nix flake repository.

## Overview

m3ta-nixpkgs is a collection of custom packages, overlays, NixOS modules, and Home Manager modules organized as a modern Nix flake. This repository follows a flakes-only approach (no channels) and provides reusable components for personal infrastructure.

## Key Concepts

### Flakes-Only Approach

This repository uses modern Nix flakes exclusively. No channels or `nix-channel` commands are needed. All dependencies are declaratively specified in `flake.nix`.

### Namespace Convention

All modules use the `m3ta.*` namespace:

- `m3ta.ports.*` - Port management
- `m3ta.mem0.*` - Mem0 service configuration
- `m3ta.*.enable` - Enable/disable modules

### Port Management

Centralized port management across hosts using the `m3ta.ports` module:

```nix
m3ta.ports = {
  enable = true;
  definitions = { mem0 = 8000; };
  hostOverrides.laptop = { mem0 = 8080; };
  currentHost = "laptop";
};
```

## Supported Systems

- `x86_64-linux` - Primary
- `aarch64-linux` - ARM Linux
- `x86_64-darwin` - macOS (Intel)
- `aarch64-darwin` - macOS (Apple Silicon)

## Quick Commands

```bash
# Validate flake
nix flake check

# Format code
nix fmt

# Build package
nix build .#<package-name>

# List outputs
nix flake show

# Enter dev shell
nix develop
```

## License

Individual packages may have their own licenses. Check each package's `meta.license` attribute.
