Belvys

Belvys is a package to fetch data through the REST API of energy portfolio management software "Belvis".

Installation

pip install belvys

Or add it to pyproject.toml.

Documentation

Documentation is hosted on readthedocs:

https://belvys.readthedocs.io/

The package defines 3 classes: Tenant, which is the main class, and Structure and Api, which it depends on.

• The Tenant class uses a structure specification (an instance of the Structure class) and an interface (an instance of the Api class) to retrieve timeseries (more specifically portfolyo.PfLine instances) from Belvis.
• The purpose of the Structure class is primarily to specify the portfolios and timeseries we are interested in. This includes original Belvis portfolios, as well as synthetic ones that are the sum of several original porfolios. It also specifies where relevant prices can be found in Belvis.
• The Api class is used to query the belvis Api and retrieve data, including the authentication part.

Repository

The git repository is hosted on github:

Developing

This project uses black to format code and flake8 for linting. We also support pre-commit to ensure these have been run. To configure your local environment please install these development dependencies and set up the commit hooks.

poetry install --with dev,test
pre-commit install

Development is done on feature branches, which are merged back into master via pull request.

Before creating a pull request:

• Merge the current state of master into the feature branch;
• Increase the version number (by running poetry version major|minor|patch) of the feature branch.

Publishing

To publish the current state of master, run the create_tag.sh script. It will create a tag from the version number and push it to github. (The version number must be unequal to a previous tag, which is automatically true if the development is only done in feature branches, and every feature branch increases the version number.) On github, a release can be drafted from the tag.
