• maser-tools for additional support programs

Read maser4py main documentation for details.

maser4py is developed in the framework of the MASER project.

Installation

To install the full package, run the following command:

pip install maser4py[all]

or use one of the extra options:

• data to get maser-data submodule features
• plot to get maser-plot submodule features
• tools to get maser-tools submodule features
• jupyter for Jupyter notebook support
• jupytext for Jupyter notebook text support
• all to install all the submodules above

For example if you want to use maser4py with maser-data and maser-plot submodules:

pip install maser4py[data,plot]

Usage

Examples of usage can be found in the examples folder.

Examples can also be run as Jupyter notebooks on Binder You can also launch a Binder environment and browse through the notebook examples.

Development

To contribute to the development of the package, you will need to install a local copy of maser4py:

git clone https://gitlab.obspm.fr/maser/maser4py.git

Then, you can install the package locally

Requirements

maser4py requirements are detailed in the pyproject.toml file

poetry

To install the package, it is recommended to use poetry:

pip install poetry

CDF file format

To use maser4py to read CDF files you have to install the CDF library and the spacepy.pycdf package.

Installing a local copy of maser4py

Use the following command to install the package from a local copy:

poetry install

Tests

Use pytest -m "not test_data_required" to skip tests that require test data (and to skip auto download).

pip install -e path/to/project/folder

Build the documentation

Use sphinx-build docs/source docs/public to build the documentation.

Manually publish maser and generate a new DOI

To publish maser with poetry you will have to build a dist package:

poetry build

And then publish the package on pypi (and/or on Gitlab, see https://python-poetry.org/docs/cli/#publish):

poetry publish

maser comes with a Python client (see .ci/zenodo.py) to interact with the Zenodo API and generate automatically a DOI for each new version of maser.

To archive maser on Zenodo:

1. Create an access token
2. Is this the first maser deposit on Zenodo ?

• Yes it's the first deposit, so you don't need any ID
• No, it's a new version of maser. Then browse to the first record of maser on Zenodo and check the URL : https://zenodo.org/record/<DEPOSITION_ID> to get the maser deposition ID.

3. Use the following command to deposit the package on Zenodo:

 python .ci/zenodo.py -p ./ -t <ACCESS_TOKEN> -a ./dist/maser4py-X.Y.Z.tar.gz  -id <DEPOSITION_ID>

4. Browse to the maser record on Zenodo, check the metadata/files and publish the package to finally generate the DOI.

Notes :

• the --sandbox keyword can be used to deposit files on the Zenodo test server
• the --publish keyword can be used to automatically publish the new record and generate the DOI. But be careful, once published, there is no way to modify a record on Zenodo without publishing a new version.
