Getting the source code

The source code is maintained on GitHub. To check out the main branch:

$ git clone

You can also browse the code online at

Preparing the development sandbox

The following steps only need to be done once to install all the tools and scripts needed for building, packaging and testing. First, create a Virtual environment. The example here uses Python 3.11, but any Python version supported by this package will work. Then install all the required tools:

$ cd dataflake.wsgi.bjoern
$ python3.11 -m venv .
$ bin/pip install -U pip wheel
$ bin/pip install -U setuptools zc.buildout tox twine

Running the tests

You can use tox to run the unit and integration tests in this package. The shipped tox configuration can run the tests for all supported platforms. You can read the entire long list of possible options on the tox CLI interface documentation page, but the following examples will get you started:

$ bin/tox -l       # List all available environments
$ bin/tox -pall    # Run tests for all environments in parallel
$ bin/tox -epy311  # Run tests on Python 3.11 only
$ bin/tox -elint   # Run package sanity checks and lint the code

Building the documentation

tox is also used to build the Sphinx-based documentation. The input files are in the docs subfolder and the documentation build step will compile them to HTML. The output is stored in docs/_build/html/:

$ bin/tox -edocs

If the documentation contains doctests they are run as well.
