| description | Use fastmod to make mass code updates to avoid many repetitive changes. |
You can occasionally use fastmod or sed to make mass updates to the codebase and avoid wasting tokens changing each case one at a time.
Before making many repetitive changes to the codebase, consider using fastmod --accept-all.
THINK HARD about how best to use fastmod as it can dramatically improve your productivity.
Example of switching the py_type function to use impl ResourceTracker instead of T: ResourceTracker:
fastmod --accept-all 'fn py_type<T: ResourceTracker>(\(.+?)<T>' 'fn py_type$1<impl ResourceTracker>'
Run and test Python code in a dedicated playground directory. Use when you need to execute Python scripts, test code snippets, investigate CPython behavior, or experiment with Python without affecting the main codebase.
