This repository uses the bdk-ffi repository as a git submodule. Here are useful tips for working with the submodule:

1. When initially cloning the repo, the bdk-ffi submodule will be empty locally. You can initiate/populate the directory by using the just submodule-init command.
2. If you make local changes to the bdk-ffi directory while developing and want to hard delete all changes and return to the exact committed version hash of the bdk-ffi repo, use the just submodule-reset command.

Before building bdkpython locally, ensure you have installed the following tools:

• Rust toolchain (rustup): Required to compile bdk-ffi. Install from rustup.rs.
• uv: Fast Python package installer and resolver. Install from Astral uv Docs.
• just (optional): Command runner used for repo tasks. Install via cargo install just or your system package manager.

Windows Users

• Windows: Rust's x86_64-pc-windows-msvc target needs the MSVC toolchain and Windows SDK. rustup-init offers to install these for you; otherwise install Visual Studio Build Tools with the Desktop development with C++ workload. The build scripts are bash, so run them from Git Bash.

1. Run one of the build scripts (skip the submodule update if you are making local changes to the bdk-ffi submodule)
2. Sync dependencies with uv
3. Create the wheel
4. Install the library
5. Run the tests

Run the build script corresponding to your operating system:

Linux:

bash scripts/generate-linux.sh

macOS (Apple Silicon / ARM64):

bash scripts/generate-macos-arm64.sh

macOS (Intel / x86_64):

bash scripts/generate-macos-x86_64.sh

Windows (Git Bash / MSYS2):

bash scripts/generate-windows.sh

Note: Pass --skip-submodule-update if you are making local changes to bdk-ffi and wish to preserve them instead of resetting to the committed submodule hash.

# Sync dependencies with uv
uv sync

# Create the wheel
uv build --wheel -v

# Install the library
uv pip install ./dist/bdkpython-*.whl --force-reinstall

# Run the tests
uv run python -m unittest --verbose

1. Generate docs
2. Build HTML Documentation

uv run python ./docs/generate_docs.py
uv run python -m sphinx -b html -W --keep-going -v docs/source docs/_build/html
