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:

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

# Validate flake
nix flake check

# Format code
nix fmt

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

# List outputs

# Enter dev shell
nix develop

License

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