Citation

If you use regolith in a scientific publication, we would like you to cite this package as

    regolith Package, https://github.com/regro/regolith

Installation

The preferred method is to use Miniconda Python <https://docs.conda.io/projects/miniconda/en/latest/miniconda-install.html>_ and install from the "conda-forge" channel of Conda packages.

To add "conda-forge" to the conda channels, run the following in a terminal. ::

    conda config --add channels conda-forge

We want to install our packages in a suitable conda environment. The following creates and activates a new environment named regolith_env ::

    conda create -n regolith_env python=3
    conda activate regolith_env

Then, to fully install regolith in our active environment, run ::

    conda install regolith

Another option is to use pip to download and install the latest release from Python Package Index <https://pypi.python.org>_. To install using pip into your regolith_env environment, we will also have to install dependencies ::

    pip install -r https://raw.githubusercontent.com/regro/regolith/main/requirements/run.txt

and then install the package ::

    pip install regolith

If you prefer to install from sources, after installing the dependencies, obtain the source archive from GitHub <https://github.com/regro/regolith/>_. Once installed, cd into your regolith directory and run the following ::

    pip install .

Support and Contribute

Diffpy user group <https://groups.google.com/g/diffpy-users>_ is the discussion forum for general questions and discussions about the use of regolith. Please join the regolith users community by joining the Google group. The regolith project welcomes your expertise and enthusiasm!

If you see a bug or want to request a feature, please report it as an issue <https://github.com/regro/regolith/issues>_ and/or submit a fix as a PR <https://github.com/regro/regolith/pulls>. You can also post it to the Diffpy user group <https://groups.google.com/g/diffpy-users>.

Feel free to fork the project and contribute. To install regolith in a development mode, with its sources being directly used by Python rather than copied to a package directory, use the following in the root directory ::

    pip install -e .

To ensure code quality and to prevent accidental commits into the default branch, please set up the use of our pre-commit hooks.

• Install pre-commit in your working environment by running conda install pre-commit.

• Initialize pre-commit (one time only) pre-commit install.

Thereafter your code will be linted by black and isort and checked against flake8 before you can commit. If it fails by black or isort, just rerun and it should pass (black and isort will modify the files so should pass after they are modified). If the flake8 test fails please see the error messages and fix them manually before trying to commit again.

Improvements and fixes are always appreciated.
