Contributing#

splinepy welcomes and appreciates discussions, issues and pull requests!

Quick start#

Once the repo is forked, one possible starting point would be creating a new python environments, for example, using conda with, for example, python=3.10

conda create -n splinepyenv python=3.10
conda activate splinepyenv
git clone git@github.com:<path-to-your-fork>
cd splinepy  # or <forkname>
git submodule update --init --recursive
git checkout -b new-feature0
pip install -e. -v --config-settings=cmake.args=-DSPLINEPY_MORE=OFF --config-settings=cmake.build-type="Debug"

--config-settings=cmake.args=-DSPLINEPY_MORE build argument builds splines up to 3D (both parametric and physical dimensions if they are part of template parameters), and that way we can reduce compile time. --config-settings=cmake.build-type="Debug" build also reduces compile time. We are experimenting with ways to reduce compile time during development. Let us know if you have a good idea!

Python style / implementation preferences#

use `PEP 8` style guide
no complex comphrehensions: preferably fits in a line, 2 lines max if it is totally necessary
use first letter abbreviations in element loops: for kv in knot_vectors
use i, j, k, l for pure index: for i, kv in enumerate(knot_vectors)
module local import with a leading underscore: from splinepy import settings as _settings
make sure function wrappers are properly documented (see, e.g., helpme.create.Creator’s member functions)

C++ style / implementation preferences#

For c++, we’ve prepared a .clang-format, with that you can just run clang-format. We closely follow naming scheme suggested by google stype guide, with a clear exception of file naming: we use [.hpp, .inl, .cpp]. Here’s another preference:

#pragma once

Automatic formatting / style check#

To check the format and style of your code use the following commands:

pip install pre-commit
precommit run -a

Local documentation build#

pip install -r docs/requirements.txt
python3 docs/source/handle_markdown.py
python3 docs/markdown/extra_docs.py
sphinx-build -b html docs/source docs/build -E
# you can now open `docs/build/index.html` with your browser
