This repository contains the Splipy packages. Splipy is a pure python library for the creation, evaluation and manipulation of B-spline and NURBS geometries. It supports n-variate splines of any dimension, but emphasis is made on the use of curves, surfaces and volumes. The library is designed primarily for analysis use, and therefore allows fine-grained control over many aspects which is not possible to achieve with conventional CAD tools.

Installation ---------The library is packaged on splipy and can be installed through pip by simply running :

pip install splipy

• Getting-started guide - tutorial page (run with jupyter to get interactive features)
• Examples page - stand-alone executables of different applications
• API documentation - technical details on all functions
• Package installation page - splipy on PyPi, packaged and ready for installation

Required

This library requires numpy and scipy. For building, cython is also required. E.g. on Ubuntu:

pip install numpy
pip install scipy
pip install cython

Optional

To use image processing tools, you need OpenCV :

pip install python-opencv

To generate the documentation you will need Sphinx:

pip install sphinx

And to run the tests you can use your favourite test runner, for example pytest:

pip install pytest pytest-benchmark pytest-cov

To install, use:

python setup.py build_ext --inplace
python setup.py install

To generate a package, use:

python setup.py sdist --dist-dir .

To generate the documentation, run in the doc folder:

make html

To push generated docs online on the gh-pages branch, run the helper script:

python push_documentation.py [remote]

where remote is the name of the remote to push to. If not given, it will be asked.

To run the tests, you can use your favourite test runner. For example, with pytest:

PYTHONPATH=. py.test --benchmark-skip

To get a report of test coverage, run:

PYTHONPATH=. py.test --benchmark-skip --cov=splipy --cov-report term-missing

You can use pylint3 to perform static code analysis on the module. This can help identify bugs and give suggestions for improvements.

To install, use:

pip3 install pylint

To perform the code analysis, use:

pylint -d C --rcfile=pylint.cfg splipy/

To make a new release, it is recommended to install bumpversion. To make a new release, run:

bumpversion <type>

where type is one of patch, minor or major. This will up the version number, create a commit and a tag. To push this to github, use:

git push --tags

After that, Travis CI should automatically build and deploy the packages to PyPi. It would be helpful to monitor the Travis build so that errors can be fixed quickly. See the list of builds.
