# OpenEO Processes Dask
[](https://python-poetry.org/)
[](https://codecov.io/github/Open-EO/openeo-processes-dask)
`openeo-processes-dask` is a collection of Python implementations of [OpenEO processes](https://processes.openeo.org/) based on the [xarray](https://github.com/pydata/xarray)/[dask](https://github.com/dask/dask) ecosystem. It is intended to be used alongside with [openeo-pg-parser-networkx](https://github.com/Open-EO/openeo-pg-parser-networkx), which handles the parsing and execution of [OpenEO process graphs](https://openeo.org/documentation/1.0/developers/api/reference.html#section/Processes/Process-Graphs). There you'll also find a tutorial on how to register process implementations from an arbitrary source (e.g. this repo) to the registry of available processes.
## Installation
Install this project via pip:
```
pip install openeo-processes-dask
```
Note that by default this only installs the json process specs. In order to install the actual implementations, add the `implementations` extra:
```
pip install openeo-processes-dask[implementations]
```
A subset of process implementations with heavy or unstable dependencies are hidden behind these further build variants:
- `openeo_processes_dask/process_implementations/ml`: `pip install openeo-processes-dask[ml]`
- `openeo_processes_dask/process_implementations/experimental`: `pip install openeo-processes-dask[experimental]`
## Development environment
openeo-processes-dask requires poetry >1.2, see their [docs](https://python-poetry.org/docs/#installation) for installation instructions.
Clone the repository with `--recurse-submodules` to also fetch the process specs:
```
git clone --recurse-submodules git@github.com:Open-EO/openeo-processes-dask.git
```
To setup the python venv and install this project into it run:
```
poetry install --all-extras
```
To add a new core dependency run:
```
poetry add some_new_dependency
```
To add a new development dependency run:
```
poetry add some_new_dependency --group dev
```
To run the test suite run:
```
poetry run python -m pytest
```
Note that you can also use the virtual environment that's generated by poetry as the kernel for the ipynb notebooks.
### Pre-commit hooks
This repo makes use of [pre-commit](https://pre-commit.com/) hooks to enforce linting & a few sanity checks. In a fresh development setup, install the hooks using `poetry run pre-commit install`. These will then automatically be checked against your changes before making the commit.
### Specs
The json specs for the individual processes are tracked as a git submodule in `openeo_processes_dask/specs/openeo-processes`.
The raw json for a specific process can be imported using `from openeo_processes_dask.specs import reduce_dimension`.
To bump these specs to a later version use:
`git -C openeo_processes_dask/specs/openeo-processes checkout <tag>`
`git add openeo_processes_dask/specs/openeo-processes`
