Summary
This pull request improves Python Fire’s CLI error handling when required positional arguments are missing.
Problem
Previously, missing required arguments resulted in a generic Python
TypeError, which exposed an internal traceback and did not clearly guide users on how to fix the issue.Solution
TypeErrorexceptions during command executionImpact
This enhancement significantly improves developer experience and usability for Python Fire–based CLIs, especially for new users unfamiliar with Python tracebacks.
Example
Before
TypeError: greet() missing 1 required positional argument: 'name'
After
ERROR: The function received no value for the required argument: name
Usage: test_fire.py NAME
