Description:

lightshow 1.2.4

Lightshow is a Python library for easily generating computational
spectroscopy input files. If you use our code, please consider citing our manuscript in the Journal of Open Source Software and our multi-code benchmark paper, which provides the methods and default parameters used in Lightshow.
Often, it can be daunting to create comprehensive, well documented
databases of materials structures and their x-ray absorption spectra.
Lightshow solves this problem, allowing new users to choose sensible
defaults for their calculations, while simultaneously exposing all
functionality for experts.
Lightshow aims to provide a "one-stop-shop" for input file
generation, and currently supports the following codes:

FEFF
VASP
OCEAN
EXCITING
Xspectra

with more on the way! The software is intended to be user-friendly,
extensively documented and tested, and extendable for those users who
wish to add additional spectroscopy functionalities. There are also a
few comprehensive tutorials to help you get started.

Installation
To install Lightshow, simply use pip
pip install lightshow

Make sure you've set your Materials Project v2 API key as well! You can find some documentation on how to query data here and how to set up your new API key here.
export MP_API_KEY="your_Materials_Project_v2_API_key"

(or preferably, add MP_API_KEY to your bash profile).
More details can be found at our documentation.
Development installation
For developers: after cloning Lightshow locally, install pre-commit via
pip install pre-commit
pre-commit
pre-commit install

and check that the tests (below) work correctly.
Running tests
For developers: tests can be run via pytest. After cloning, simply use
pytest lightshow/_tests

or with coverage
pytest -v --cov --cov-report xml lightshow/_tests

Contributing
We welcome any and all contributions by the community, including pull requests, bug reports, etc.
Please see our contributing document for more details!
Adding new spectroscopy codes
Adding new spectroscopy codes requires one to inherit the _BaseParameters class from lightshow.parameters._base.
The new Parameters(_BaseParameters) object should have a write() method, which must take a target directory as an
argument, as well as any other keyword arguments require to write the input file (most notably, the Pymatgen structure,
either a unit or super cell). The name property must also be defined (corresponding to the name of the calculation,
e.g. "VASP"). Take a look at the examples in the lightshow.parameters module for more details!
