Local Development

Requirements:

• Python 3.9+
• Hatch
• CMake 3.27+

Run the example:

# choose one:
hatch run pyside6:example

# pyside2 may not be available for all python versions or platforms
hatch run pyside2:example

Setup your local environment

Create a repo relative .venv/ dir:

hatch env create

Run the tests:

hatch test

Build the wheel for your platform:

hatch build -t wheel

Recompile the C++ project

hatch run compile

The cmake project is not intended to be run on its own but it is possible to do it. The pybind11 dependency will be available after creating the default virtual environment and passing its python executable path to cmake via Python_EXECUTABLE. Some IDE's may do this for you when a python environment is activated in their configuration.

Manual CMake build

cmake -S . -B cmake-build-release -G Ninja
cmake --build cmake-build-release -j 8
cmake --install cmake-build-release --prefix src

Acknowledgements

The core C++ code for the blurhash functions was source from https://github.com/Nheko-Reborn/blurhash under the Boost Software License. Some minor modifications were made.

This project is made possible by pybind11 and scikit-build-core. Multi-platform wheels are generated using the cibuildwheel project.
