Python 3.7 or higher.
The dependencies can be found in the requirements.txt and requirements-dev.txt files.
To install dependencies, run:
pip3 install -r requirements.txt
pip3 install -r requirements-dev.txt
To enable dependency scanning an extra tool is required: scancode-toolkit
pip3 install typecode-libmagic
pip3 install scancode-toolkit-mini
More details on Python packaging/distribution can be found here, here, and here.
It is good practice to set up a Virtual Env (venv) to isolate and simplify development/testing. If using PyCharm, please follow these instructions.
In order to develop/test a Python package, it is necessary to register the package locally. This can be done using the following command:
python3 setup.py develop --user
There is also a Makefile in the repository, which provide helpers to achieve this:
make dev_setup
The client now makes use of REST & gRPC. For gRPC specific environment variables please look here.
Packaging the library for deployment is done using setup.
The version of the package is defined in the scanoss init file. Please update this version before packaging/releasing an update.
To package the library, please run:
make dist
This project uses twine to upload packages to pypi.org. In order to run twine, a user needs to be registered with both TestPyPI and PyPI. Details for using TestPyPI can be found here and PyPI here.
Once the credentials have been stored in $HOME/.pypirc, the following command can be run:
make publish_test
This will deploy the package to TestPyPI. Run some tests to verify everything is ok.
Then deploy to prod:
make publish
This will deploy the package to PyPI.
The package will then be available to install using:
pip3 install scanoss
