PyPI version

Information for developers

There is a Makefile for all the following tasks (and more). Type make to print the available targets.

Install from source

To install from source run:

python3 setup.py install

Install the requirements

To install the requirements run:

pip3 install -r requirements.txt

To generate a requirements file (usually requirements.txt), that you commit with your project, run:

pip3 freeze > requirements.txt

Testing

Please note that testing requires launching the complete DSP API stack which is based on docker images. Therefore, we recommend installing the docker desktop client.

To run the complete test suite:

make test

Code style

When contributing to the project please make sure you use the same code style rules as we do. We use autopep8 and mypy. The configuration is defined in pyproject.toml in the root directory of the project.

[tool.autopep8]
max_line_length = 180
in-place = true
experimental = true

[tool.mypy]
ignore_missing_imports = true
follow_imports = "silent"
show_column_numbers = true
strict = true

You can use the configuration with autopep8 --global-config pyproject.toml [file path] and mypy --config-file pyproject.toml [file path].

If you are using PyCharm we recommend installing autopep8 as external tool. You can then use it with right-click on the file > External Tools > autopep8 to reformat files in-place. mypy is available as plugin.

For formatting Markdown files (*.md) we use the default styling configuration provided by PyCharm.

Publishing

Publishing is automated with GitHub Actions and should not be done manually. Please follow the Pull Request Guidelines. If done correctly, when merging a pull request into main, the release-please action will create or update a pull request for a release. This pull request will follow semantic versioning and update the change log. Once all desired features are merged, the release can be executed by merging this release pull request into main. This will trigger actions that create a release on GitHub, on PyPI and the docs.

Please ensure you have only one pull request per feature.

Publishing manually

Publishing is automated with GitHub Actions and should not be done manually. If you still need to do it, follow the steps below.

Generate the distribution package. Make sure you have the latest versions of setuptools and wheel installed:

python3 -m pip install --upgrade pip setuptools wheel
python3 setup.py sdist bdist_wheel

You can install the package locally from the dist:

python3 -m pip ./dist/some_name.whl

Upload package works also with make:

make dist
make upload

For local development:

python3 setup.py develop

Contributing to the documentation

The documentation is a collection of markdown files in the docs folder.
After updates of the files, build and check the result with the following commands:

make build-docs
make serve-docs 

To update the changes to the official documentation pages run:

make publish-docs
