Custom post-processor #22

Closed forman closed 3 years ago

forman commented 3 years ago

Closes #21

You can now provide your Python code for customization of the datasets read and written. (#16)
- input/custom_preprocessor: "module:function" is called on each input after optional variable selection.
- process/custom_processor: "module:function" is called after optional renaming and before optional rechunking.
- output/custom_postprocessor: "module:function" is called before the final dataset is written. (#21)
All three "function"s are expected to receive an xarray.Dataset object as only argument and return the same or modified xarray.Dataset object. Note: to let Python import "module" that is not a user package, you can extend the PYTHONPATH environment variable before calling nc2zarr:
```
export PYTHONPATH=${PYTHONPATH}:path/to/my/modules
nc2zarr ...
```
