wood_nano

Repository wood_nano has submodule wood in src directly. For new clones incase there is nothing in the src/wood folder do the following:

•   git submodule update --init --recursive

wheels

This repository contains a tiny project showing how to create C++ bindings using nanobind and scikit-build-core. It was derived from the corresponding pybind11 example project developed by @henryiii.

Installation

1. Clone this repository
2. Run pip install ./wood_nano

Afterwards, you should be able to issue the following commands (shown in an interactive Python session):

>>> import nanobind_example
>>> nanobind_example.add(1, 2)

CI Examples

The .github/workflows directory contains two continuous integration workflows for GitHub Actions. The first one (pip) runs automatically after each commit and ensures that packages can be built successfully and that tests pass.

The wheels workflow uses cibuildwheel to automatically produce binary wheels for a large variety of platforms. If a pypi_password token is provided using GitHub Action's secrets feature, this workflow can even automatically upload packages on PyPI.

Wood submodule and download dependecies

cd ~/brg/2_code/wood_nano/src
git submodule add https://github.com/petrasvestartas/wood.git
cd wood
sudo '/home/petras/brg/2_code/wood_nano/src/wood/install_ubuntu.sh'

For update:

git submodule foreach git pull origin main
sudo rm -r build

Link wood dependencies to nanobind

• Ubuntu - linked, Check: a) PCH is not speeding the build, b) SQL has no be unlocked like this sudo chown -R, be aware that the .sh file installs gmp and mpfr in ubuntu, not as a cmake source code.
• Windows - linked, Check: a) C:\Users\petras.conda\envs\wood\Lib\site-packages\wood_nano must have cgal libgmp-10.dll and libmpfr-4.dll, it would be great that gmp and mpfr would be compiled together into one single .pyd file.
• Mac - not linked

Code wrapping

• for development you need to use pip install . and even you changed init.py
• function based on the EDX tutorial
• Process: - add c++ and binded method in nanobind_binding.cpp - run pip install -e . to check if there are no C++ mistake - import the method in src/wood_nano/init.py - test the imported method in tests/test_basic.py - compas_wood - create a file called src/compas_wood/binding/binding_read_xml_polylines.py - compas_wood - add this name in init.py - compas_wood - fill the contents of the file and create a test under if name == "main" - compas_wood - write docstrings under the method - compas_wood - invoke docs and check the result

• add requirements wood-nano
• rewrite examples
• compas_wood must be installable by pip install compas_wood
• documentation based on edx tutorials
• create compas_model with vizualization

In this case, the default message is pre-filled, but you can modify it if needed. To proceed with the merge and accept the default commit message, you can follow these steps:

Press i on your keyboard to enter insert mode in the text editor. Make any changes to the commit message if necessary. Once you're done, press Esc to exit insert mode. Type :wq to save the commit message and exit the text editor. If you're using Vim, this command writes the changes and quits the editor.
