Utility that sorts the names in the auto mappings defines in the auto modules in alphabetical order. | |
Use from the root of the repo with: | |
```bash | |
python utils/sort_auto_mappings.py | |
``` | |
to auto-fix all the auto mappings (used in `make style`). | |
To only check if the mappings are properly sorted (as used in `make quality`), do: | |
```bash | |
python utils/sort_auto_mappings.py --check_only | |
``` | |
