# Saclay_format (v0.2.15)

This repository contains a proposal format definition to exchange inputs/outputs
between some mean-field theory codes in the nuclear physics and astrophysics communities.
This format relies on a series of custom binary files containing the raw data along with
a YAML header containing metadata. It adheres to the results of the 05/2025 and 10/2025 ESNT
workshops entitled *"Simulating dense matter on three-dimensional coordinate space meshes (part I and II)"*.

## Content

* `saclay_format` — Python3 package to parse and visualize this format
* `docs` — documentation of the format (not yet up to date)
* `examples` — nuclear mean-field outputs in this format
* `tests` — unit tests of the package

## Requirements

* `pyyaml` — Python3 package for YAML parsing
* `h5py` — Python3 package for HDF5 parsing

## Installation via PyPI

The parser is available as a PyPI package:
[https://pypi.org/project/saclay-format/](https://pypi.org/project/saclay-format/)

Install it using pip:

```bash
pip install saclay-format
```

This also installs several command-line scripts:

* `saclay_format_ev8_to_ev1`
* `saclay_format_ev1_to_cr1`
* `saclay_format_hdf5_yaml_converter`
* `saclay_format_compute_densities`
* `saclay_format_visualisation_rho`
* `saclay_format_visualisation_rho_TD`
* `saclay_format_visualisation_ascii`

## Running the parser

From a Python terminal, import the package and use its `read()` and `write()` methods.
Example:

```python
import saclay_format

data = saclay_format.read('file.yml')
# Modify or inspect data...
saclay_format.write(data, 'file_out.h5')
```

To run the unit tests:

```bash
cd tests/
python3 test_saclay_format.py
```

python3 ../../src/saclay_format/ev8_to_ev1.py Ca40_HF_SLy4.h5 -o Ca40_HF_SLy4_ev1.h5
python3 ../../src/saclay_format/ev1_to_cr1.py Ca40_HF_SLy4_ev1.h5 -o Ca40_HF_SLy4_cr1.h5
```

### Visualization test

Static:

```bash
python3 ../../src/saclay_format/visualisation_rho.py reaction_alpha_alpha_3MeV_header.yml
```

Dynamic:

```bash
python3 ../../src/saclay_format/visualisation_rho_TD.py reaction_alpha_alpha_3MeV_header.yml
```

Conversion and round-trip test:

```bash
python3 ../../src/saclay_format/hdf5_yaml_converter.py -h5 reaction_alpha_alpha_3MeV_header.yml
mv reaction_alpha_alpha_3MeV_header.h5 reaction_alpha_alpha_3MeV_converted.h5
python3 ../../src/saclay_format/visualisation_rho_TD.py reaction_alpha_alpha_3MeV_converted.h5
python3 ../../src/saclay_format/hdf5_yaml_converter.py -yaml reaction_alpha_alpha_3MeV_converted.h5
python3 ../../src/saclay_format/visualisation_rho_TD.py reaction_alpha_alpha_3MeV_converted.yaml
rm reaction_alpha_alpha_3MeV_converted*
```
