What is it?

Pythran is a python to c++ compiler for a subset of the python language. 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.

Debian/Ubuntu

  1. Gather dependencies:

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

    $> sudo apt-get install libboost-python-dev libgmp-dev libboost-dev git cmake
    $> sudo apt-get install python-ply python-networkx python-numpy
  2. Use easy_install or pip:

    $> pip install pythran

or

  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

Mac OSX

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

$> brew install boost-python
$> brew install gmp
$> brew install cmake

$> easy_install pip

$> pip install pythran

Depending on your setup, you may need to add the following to your \~/.pythranrcfile:: [user] cxx=g++-4.9 ArchLinux ========= Using `yaourt`:: $> yaourt -S python2-pythran-git Other Platform ============== See MANUAL file. Basic Usage ----------- A simple pythran input could bedprod.py:: #pythran export dprod(int list, int list) def dprod(l0,l1): 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. 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 thepythran/tests/cases/`` directory from the sources.
