Dionysus 2
==========
Dionysus is a computational topology package focused on
persistent homology. It is written in C++, with Python bindings.
The second version (`previous version <http://mrzv.org/software/dionysus/>`_)
is re-written from scratch, which helps it accomplish a few goals:
* `Modified BSD license <https://github.com/mrzv/dionysus/blob/master/LICENSE.txt>`_ (because GPL causes too many problems in academic software).
* No dependency on Boost.Python; Dionysus 2 uses (and includes) `PyBind11 <https://github.com/pybind/pybind11>`_ instead, which greatly simplifies installation.
* Cleaner, more consistent internal design (for example, all algorithms support arbitrary fields).
* Some new algorithms, e.g., `omni-field persistence <http://mrzv.org/software/dionysus2/tutorial/omni-field.html#omni-field>`_ and Wasserstein and bottleneck `distance computation <http://mrzv.org/software/dionysus2/tutorial/basics.html#diagram-distances>`_ from `Hera <https://bitbucket.org/grey_narn/hera>`_.
* A few `plotting <http://mrzv.org/software/dionysus2/tutorial/plotting.html#plotting>`_ routines, based on `Matplotlib <https://matplotlib.org/>`_.
* Better integration with `NumPy <http://www.numpy.org/>`_.
Features that haven't (yet) made it over from `Dionysus 1 <http://mrzv.org/software/dionysus>`_ include vineyards.
Alpha shape filtrations are available via `DioDe <https://github.com/mrzv/diode>`_.
**Dependencies:**
* `Boost <http://www.boost.org/>`_, although Dionysus 2 doesn't link any of its libraries, so it's considerably easier to build the project.
* (Optional) `SciPy <https://www.scipy.org/>`_ for the LSQR routine used in `circular coordinates <http://mrzv.org/software/dionysus2/tutorial/cohomology.html#circular>`_.
* (Optional) `Matplotlib <https://matplotlib.org/>`_ for plotting.
**Requirements:**
* Boost needs to be at least version 1.55.
* If you are using GCC, the oldest supported version is 5.4.
**Contact:**
* please use the `dionysus mailing list <https://groups.io/g/dionysus/>`_
for all questions and discussion related to the library;
* GitHub's `issue tracker <https://github.com/mrzv/dionysus/issues>`_
is a central location for bug reports and feature requests.
Get, Build, Install
-------------------
The simplest way to install Dionysus, as a Python package, is from `PyPI <https://pypi.org/project/dionysus/>`_:
.. parsed-literal::
pip install --verbose dionysus
Pass ``--upgrade`` to ``pip``, if you have already installed some version of Dionysus.
Alternatively, you can install it directly from the development repository (this gives you the latest version):
.. parsed-literal::
pip install --verbose `git+https://github.com/mrzv/dionysus.git <https://github.com/mrzv/dionysus.git>`_
Alternatively, you can clone and build everything by hand.
To get Dionysus 2, either clone its `repository <https://github.com/mrzv/dionysus>`_:
.. parsed-literal::
git clone `<https://github.com/mrzv/dionysus.git>`_
or download it as a `Zip archive <https://github.com/mrzv/dionysus/archive/master.zip>`_.
To build the project::
mkdir build
cd build
cmake ..
make
To use the Python bindings, either launch Python from ``.../build/bindings/python`` or add this directory to your ``PYTHONPATH`` variable, by adding::
export PYTHONPATH=.../build/bindings/python:$PYTHONPATH
to your ``~/.bashrc`` or ``~/.zshrc``.
