Usage

All scripts are invoked through the ./run symlink at workspace root:

./run <command> [options]

Quick Start

First time setup:

./run install              # Install all dependencies (5-10 min)
./run install --build      # Install and build everything
./run install --test       # Install, build, and test (full validation)

Development workflow:

./run test                 # Run unit tests
./run build                # Build TypeScript packages
./run dev imagen-app       # Start development server

Available Commands

install

Install dependencies for all packages and services.

./run install              # Install everything
./run install --ts         # Install only TypeScript packages
./run install --py         # Install only Python services
./run install --build      # Install and build everything
./run install --test       # Install, build, and test
./run install --help       # Show install command help

What it does:

• TypeScript: Runs npm install in each package/monorepo
• Python: Creates .venv and runs pip install -e . in each service

Options:

• --ts, --typescript: Install only TypeScript packages
• --py, --python: Install only Python services
• --build: Build TypeScript packages after installing
• --test: Run tests after installing (implies --build)

Options:

• --all: Run all unit tests (default)
• --unit: Run only unit tests (no GPU)
• --gpu: Run all tests including GPU integration tests

Use case: Fast pre-commit validation without full build.

Adding New Commands

To add a new command:

1. Create command handler in scripts/run/<command>_command.py:

"""New command handler."""

import argparse
from pathlib import Path


def new_command(args, workspace_root: Path):
    """Handle new command.

    Args:
        args: Command-line arguments
        workspace_root: Path to workspace root

    Returns:
        Exit code (0 = success, non-zero = failure)
    """
    parser = argparse.ArgumentParser(
        prog="./run new",
        description="Description of new command",
    )

    # Add arguments
    parser.add_argument("--option", help="Example option")

    parsed_args = parser.parse_args(args)

    # Implement command logic
    print(f"Running new command with option: {parsed_args.option}")

    return 0


def register_new_command(runner):
    """Register the new command.

    Args:
        runner: ScriptRunner instance
    """
    runner.register_command(
        "new",
        new_command,
        "Short description for help text",
    )

2. Register command in scripts/run/script_runner.py:

def main():
    """Main entry point."""
    runner = ScriptRunner()

    # Import and register commands
    import importlib.util
    script_path = Path(__file__).resolve()

    # Existing commands
    test_cmd_path = script_path.parent / "test_command.py"
    test_cmd = load_command(test_cmd_path)
    test_cmd.register_test_command(runner)

    # Add new command
    new_cmd_path = script_path.parent / "new_command.py"
    new_cmd = load_command(new_cmd_path)
    new_cmd.register_new_command(runner)

    # Run
    sys.exit(runner.run())

3. Test the command:

./run new --help
./run --help  # Verify it appears in command list

Architecture

ScriptRunner Class

Main dispatcher that:

• Parses top-level command
• Routes to appropriate command handler
• Provides unified help text
• Handles errors and exit codes

Command Handlers

Each command handler:

• Defines its own argument parser
• Implements the command logic
• Returns exit code (0 = success)
• Registers itself with ScriptRunner

Benefits

• Unified interface: Single entry point for all commands
• Modular: Easy to add new commands
• Self-documenting: Help text generated from parsers
• Extensible: Commands can import shared utilities
• Type-safe: Python type hints throughout

Legacy Scripts

Some scripts remain as standalone bash scripts:

• test-all.sh - Original test runner (still supported)

The ./run command provides a Python-based alternative with better:

• Argument parsing
• Help text
• Error handling
• Extensibility

Dependencies

Required:

• Python 3.10+

No external dependencies: Uses only Python standard library.

Testing

Test commands should be idempotent and safe to run repeatedly.

# Test the script runner itself
python3 scripts/run/script_runner.py --help
python3 scripts/run/script_runner.py test --help

# Test via symlink
./run --help
./run test --help

Notes

• The ./run symlink resolves to scripts/run/script_runner.py
• Commands use importlib to avoid relative import issues
• All paths are resolved relative to workspace root
• Exit codes follow Unix conventions (0 = success)
