Standalone Script

Standalone Script

Overview

Create a single-file Python script that runs via uv run --script, declares dependencies in a PEP 723 block, and uses Typer for a future-proof CLI.

Workflow

1. Gather requirements: script purpose, inputs/outputs, dependencies, and any file paths.
2. Start from assets/pep723_typer_script.py and copy it into the target script.
3. Update the PEP 723 block:
   • Keep requires-python = ">=3.13" as the default.
   • List all dependencies, always include typer.
4. Implement the logic inside the Typer command(s) and keep it single-file.
5. Ensure the shebang is the very first line: #!/usr/bin/env -S uv run --script.
6. Update the Typer command help string to describe what the script does.
7. Mark the script executable after writing it (e.g., chmod +x <script>).
8. Provide run instructions (uv run --script script.py).

Requirements

• Always use Typer even if no arguments are currently needed.
• Do not create a package layout or pyproject; keep everything in one script.
• Keep the file ASCII unless the user explicitly needs Unicode.
• Prefer small helper functions over complex classes unless necessary.

Assets

Use assets/pep723_typer_script.py as the starting template for new scripts.
