Forward-time population genetic simulation in Python
Project description
fwdpy11
*************************
This is the README for fwdpy11_, which is a Python package for forward-time population genetic simulation. It uses
fwdpp_ as its C++ back-end.

Features
-----------------------
* Picklable population objects
* Parallel computation via multiprocessing_ or concurrent.futures_.
* Custom temporal samplers to analyze populations *during* a simulation may be written in pure Python.
Dependencies
-----------------------
The following must be present on your system:
* GSL_. This is a C library. It is available via `conda`.
* pybind11_. This should be installed via `pip` or `conda` as appropriate for your system.
fwdpy11_ also uses fwdpp_, which is included as a submodule.
License
-----------------------
GPLv3 or later (See COPYING)
Suppored Python version
-----------------------
fwdpy11 is written for Python 3. We will not modify the package to be compatible with Python 2.7.
.. code-block:: bash
git submodule init
git submodule update
python setup.py build_ext -i
python test.py
.. note::
The clang compiler is the assumed default on OS X. However, life is simpler
if you use gcc. The setup.py takes a --gcc option that eliminates OS X-specific
(really Xcode clang-specific) features so that an OS X/gcc build is possible.
Installation
---------------------------------
Using pip on OS X and Linux (or pip3 as appropriate for your system):
.. code-block:: bash
pip install --upgrade fwdpy11
If you prefer a pip install on OS X using GCC instead of clang:
.. code-block:: bash
pip install --upgrade fwdpy11 --install-option=--gcc
You may or may not need to prefix the above with
.. code-block:: bash
CC=gcc CXX=g++
depending on whether or not your user's `$PATH` is set up to override Xcode's symlink of gcc to clang.
Caution
==================================
We use the GitHub "release_" mechanism to make stable versions available. However, GitHub releases to not include the
sub-modules, meaning that the releases themselves cannot be used for installation. (A related irony is that the Zenodo
DOI for the releases are somewhat meaningless.)
To install a specific release:
1. Use pip (see above). This is the recommended approach if you do not use conda.
2. Install from bioconda. This is the recommended approach.
3. Clone the repo, checkout the release, and update submodules:
.. code-block:: bash
git clone http://github.com/molpopgen/fwdpy11
cd fwdpy11
git submodule init
git submodule update
The latter method is probably the least appealing.
We have a strict policy of putting releases on PyPi and bioconda_. If there is a release on PyPi but not on bioconda_,
then that is because we identified a bug and pushed a new release before the bioconda_ build happend. It happens.
That's life.
Enabling debugging symbols in the C++ code
------------------------------------------------------------------
.. code_block:: bash
python setup.py build_ext -i --debug
Enabling assertions in the C++ code
------------------------------------------------------------------
The C++ code uses C's assert macros in several places. These are disabled by default. However, it can be useful to
enable them when hacking the code. To do so:
.. code-block:: bash
python setup.py build_ext -i --assert
.. note::
Never install the package compiled in assert mode! First, things will run much more slowly.
Second, triggering an assertion will cause the Python interpreter to crash. These assertions
exist as a brute-force method to help developers quickly identify bugs.
Bioconda
=================================
fwdpy11 is available through bioconda_ for Linux and for OS X:
.. code-block:: bash
conda install -c bioconda fwdpy11
The OS X build is built using gcc.
