What is Barril?

Python package to manage units for physical quantities.

Quick example:

from barril.units import Scalar

s1 = Scalar(10, "m")
s2 = Scalar(500, "cm")
assert s1 + s2 == Scalar(15, "m")

Features

• Pre-defined unit database containing several physical quantities for the Oil & Gas industry.
• Data types with an associated unit: Scalar, Array, Quantity, FixedArray.
• Automatic conversion during arithmetic operations.

Development

For complete description of what type of contributions are possible, see the full CONTRIBUTING guide.

Here is a quick summary of the steps necessary to setup your environment to contribute to barril.

1. Create a virtual environment and activate it:

   $ python -m virtualenv .env
   $ .env\Scripts\activate  # windows
   $ source .env/bin/activate  # linux
   

   Note

   If you use conda, you can install virtualenv in the root environment:

   $ conda install -n root virtualenv
   

   Don't worry as this is safe to do.

2. Update pip:

   $ python -m pip install -U pip
   

3. Install development dependencies:

   $ pip install -e .[testing]
   

4. Install pre-commit:

   $ pre-commit install
   

5. Run tests:

   $ pytest --pyargs barril
   

6. Generate docs locally:

   $ tox -e docs
   

   The documentation files will be generated in docs/_build.

Release

A reminder for the maintainers on how to make a new release.

Note that the VERSION should folow the semantic versioning as X.Y.Z Ex.: v1.0.5

1. Create a release-VERSION branch from upstream/master.
2. Update CHANGELOG.rst.
3. Push a branch with the changes.
4. Once all builds pass, push a VERSION tag to upstream.
5. Merge the PR.
