What is it?
-----------

Pythran is a Python to c++ compiler for a subset of the Python language, with a
focus on scientific computing. It takes a Python module annotated with a few
interface description and turns it into a native python module with the same
interface, but (hopefully) faster.

It is meant to efficiently compile **scientific programs**, and takes advantage
of multi-cores and SIMD instruction units.

Pythran development is currently done using Python version **2.7**.

Installation
------------

Pythran sources are hosted on https://github.com/serge-sans-paille/pythran

Pythran releases are hosted on http://pypi.python.org/pypi/pythran

Pythran is available through Conda on https://conda.anaconda.org/serge-sans-paille

Debian/Ubuntu
=============

Using ``pip``
*************

1. Gather dependencies:

Pythran depends on a few Python modules and several C++ libraries. On a debian-like platform, run::

$> sudo apt-get install libgmp-dev libblas-dev
$> sudo apt-get install python-dev python-ply python-networkx python-numpy

2. Use ``easy_install`` or ``pip``::

$> pip install pythran

Using a private debian repo
***************************

1. Add serge_sans_paille's debian server to your `source.list`, following the
instruction given in http://serge.liyun.free.fr/serge/debian.html

2. Run the classic::

$> sudo apt-get update
$> sudo apt-get install pythran

Using ``conda``
***************

1. Install ``conda``, following the instruction given in
http://conda.pydata.org/docs/install/quick.html

2. Run::

$> conda install -c serge-sans-paille pythran

Mac OSX
=======

Using brew (http://brew.sh/)::

$> brew install gmp
$> brew install cmake

$> easy_install pip

$> pip install numpy pythran

Depending on your setup, you may need to add the following to your \\~/.pythranrc`` file::

[compiler]
CXX=g++-4.9
CC=gcc-4.9

ArchLinux
=========

Using `yaourt`::

$> yaourt -S python2-pythran-git

Windows
=======

Using WinPython (http://winpython.github.io), start the WinPython prompt and run::

% pip install pythran


Other Platform
==============

See MANUAL file.


Basic Usage
-----------

A simple pythran input could be ``dprod.py``::

"""
Naive dotproduct! Pythran supports numpy.dot
"""
#pythran export dprod(int list, int list)
def dprod(l0,l1):
"""WoW, generator expression, zip and sum."""
return sum(x * y for x, y in zip(l0, l1))

To turn it into a native module, run::

$> pythran dprod.py

That will generate a native dprod.so that can be imported just like the former
module::

$> python -c 'import dprod' # this imports the native module instead


Documentation
-------------

The user documentation is available in the MANUAL file from the doc directory.

The developer documentation is available in the DEVGUIDE file from the doc
directory. The also is a TUTORIAL file for those who don't like reading
documentation.

A todo list is maintained in the eponymous TODO file.

The CLI documentation is available from the pythran help command::

$> pythran --help

Some extra developer documentation is also available using pydoc. Beware, this
is the computer science incarnation for the famous Where's Waldo? game::

$> pydoc pythran
$> pydoc pythran.typing


Examples
--------

See the ``pythran/tests/cases/`` directory from the sources.
