USER: add a main func so i can run this script with a model name on the cmd line and print the results
ASSISTANT: Here are the changes to add a `main` function that allows running the script with a model name from the command line and printing the results:
aider/models.py
```python
<<<<<<< SEARCH
=======
import sys
def main():
if len(sys.argv) != 2:
print("Usage: python models.py <model_name>")
sys.exit(1)
model_name = sys.argv[1]
matching_models = fuzzy_match_models(model_name)
if matching_models:
print(f"Matching models for '{model_name}':")
for model in matching_models:
print(model)
else:
print(f"No matching models found for '{model_name}'.")
if __name__ == "__main__":
main()
>>>>>>> REPLACE
```
The `main` function does the following:
1. It checks if the script is called with exactly one command-line argument (the model name). If not, it prints the usage instructions and exits with an error code.
2. It retrieves the model name from the command-line argument using `sys.argv[1]`.
3. It calls the `fuzzy_match_models` function with the provided model name to get the list of matching models.
4. If matching models are found, it prints a message indicating the matching models for the given model name and then prints each matching model on a separate line.
5. If no matching models are found, it prints a message indicating that no matching models were found for the given model name.
The `if __name__ == "__main__":` block ensures that the `main` function is only executed when the script is run directly, not when it is imported as a module.
With these changes, you can run the script from the command line by providing a model name as an argument, and it will print the matching models or a message if no matches are found.
