Features

• Easy plugin management
• Built-in package resolution
• Python integration support

Python Package Management

This project uses uv for handling Python packages. With uv, you don't need to worry about Python or plugin versioning—uv automatically handles dependency resolution and environment isolation for you.

Commands

Getting Started

# Initialize a new pipeline file in the current directory
r2x init

# Initialize with custom filename
r2x init my-pipeline.yaml

The r2x init command creates a template pipeline file with:

• Example variables for substitution
• Multiple pipeline examples
• Plugin configuration templates
• Comments explaining all features

You can then edit the file to configure your own pipelines.

Python & Virtual Environment Management

# Install or update Python version
r2x python install 3.13

# Get the Python executable path (useful for scripting)
r2x python path

# Show current Python configuration
r2x python show

# Manage virtual environment
r2x venv              # Recreate venv (prompts for confirmation)
r2x venv -y/--yes     # Skip confirmation
r2x venv path         # Show venv path

# Get or set custom venv path
r2x venv path /path/to/custom/venv

# Automated venv recreation
R2X_VENV_YES=1 r2x venv  # Skip confirmation with environment variable

Install packages in your managed venv:

uv pip install <package> --python $(r2x python path)

Pipeline Management

# List available pipelines
r2x run pipeline.yaml --list

# Execute a pipeline
r2x run pipeline.yaml my-pipeline

# Show pipeline flow without executing (--dry-run)
r2x run pipeline.yaml my-pipeline --dry-run

# Save pipeline output to file
r2x run pipeline.yaml my-pipeline -o output.json

The --dry-run flag displays which plugins produce/consume stdout, helping you understand data flow between pipeline stages before execution.

Plugin Management

# List installed plugins
r2x list

# Install a plugin
r2x install <package>

# Run a plugin directly
r2x run plugin my-plugin [args...]

# Show plugin help
r2x run plugin my-plugin --show-help

System Integration

# Load and inspect a JSON system file
r2x read system.json

# Load from stdin and open IPython with system available
cat system.json | r2x read
