A Ruby gem providing a CLI for Factorio MOD management, settings synchronization, and game control.

Factorix simplifies Factorio MOD management by providing:

• A CLI tool for everyday MOD operations
• Automatic dependency resolution and validation
• JSON-based MOD settings export/import
• Save file synchronization capabilities

• MOD Discovery & Download: Search and download MODs from the Factorio MOD Portal
• Dependency Management: Automatic dependency resolution and validation with graph-based analysis
• MOD State Management: Enable/disable MODs with automatic handling of dependencies and dependents
• Installation & Uninstallation: Install MODs directly from the portal or uninstall existing MODs
• Save File Sync: Synchronize MOD states and startup settings from Factorio save files
• Settings Management: Export/import MOD settings in JSON format
• Blueprint Conversion: Decode/encode Factorio blueprint strings to/from JSON
• MOD Portal Integration: Upload new MODs or update existing ones, edit metadata
• Game Control: Launch Factorio from the command line
• Game Download: Download Factorio game files (alpha, expansion, demo, headless)
• Cross-platform Support: Works on Windows, Linux, macOS, and WSL

• Ruby (non-EOL versions)
• Factorio API Key (required for uploading MODs and editing MOD metadata)
  • Obtain your API key from Factorio Profile

For uploading MODs or editing MOD metadata, set the FACTORIO_API_KEY environment variable:

export FACTORIO_API_KEY=your_api_key_here

API key is not required for managing local MODs.

For downloading MODs from the MOD Portal (including via factorix mod install) or downloading the game itself, service credentials are required. These are automatically loaded from player-data.json if you have logged into Factorio, or you can set FACTORIO_USERNAME and FACTORIO_TOKEN environment variables.

Factorix auto-detects Factorio installation paths for Steam installations. For other environments or to override the detected paths, create a configuration file.

Find configuration file location:

factorix path --json | jq -r .factorix_config_path

Create configuration file:

# Copy example configuration
cp example/config.rb ~/.config/factorix/config.rb

# Edit the configuration
$EDITOR ~/.config/factorix/config.rb

Configurable paths:

• executable_path - Path to Factorio executable
• user_dir - Path to Factorio user directory (MODs, saves, settings)
• data_dir - Path to Factorio data directory

Example configuration:

Factorix.configure do |config|
  config.runtime.executable_path = "/Applications/Factorio.app/Contents/MacOS/factorio"
  config.runtime.user_dir = "#{Dir.home}/Library/Application Support/factorio"
  config.runtime.data_dir = "/Applications/Factorio.app/Contents/data"
end

See example/config.rb for platform-specific examples and additional configuration options.

Alternative configuration path:

You can specify a custom configuration file path using the --config-path option or FACTORIX_CONFIG environment variable:

# Using CLI option
factorix mod list --config-path=/path/to/config.rb

# Using environment variable
export FACTORIX_CONFIG=/path/to/config.rb
factorix mod list

Run factorix --help to see available commands, or factorix <command> --help for command-specific usage and examples.
