Python APIs

Build

C-API backend (default)

make sync

This downloads the latest shared liblbug binary (via upstream download-liblbug.sh) and syncs the project with dev dependencies. The Python package is installed directly from src_py/, so the standalone workflow no longer depends on ./build/ladybug.

Run tests with:

uv run pytest

Pybind backend from inverted layout

If your checkout layout is:

• ladybug-python/ (this repo)
• ../ladybug/ (main Ladybug repo as a sibling checkout)

then build the pybind extension through the Ladybug top-level build with:

make build-pybind-subdir

This uses LBUG_SOURCE_DIR (default: ../ladybug) to configure this repo's CMake build against the Ladybug source checkout and writes _lbug* into ./build/ladybug.

Run tests against that pybind build with:

make test-pybind-subdir

Override the source tree location when needed:

make build-pybind-subdir LBUG_SOURCE_DIR=/path/to/ladybug
