|
========
|
|
|
|
Building the libtorrent python bindings will produce a shared library (DLL)
|
|
which is a python module that can be imported in a python program.
|
|
|
|
The only supported build system for the bindings are currently boost build. To
|
|
set up your build environment, you need to add some settings to your
|
|
``$BOOST_BUILD_PATH/user-config.jam``.
|
|
|
|
Make sure your user config contains the following line::
|
|
|
|
using python : 2.3 ;
|
|
|
|
Set the version to the version of python you have installed or want to use. If
|
|
you've installed python in a non-standard location, you have to add the prefix
|
|
path used when you installed python as a second option. Like this::
|
|
|
|
using python : 2.3 : /usr ;
|
|
|
|
The bindings require *at least* python version 2.2.
|
|
|
|
For more information on how to install and set up boost-build, see the
|
|
`building libtorrent`_ section.
|
|
|
|
.. _`building libtorrent`: building.html#step-2-setup-bbv2
|
|
|
|
Once you have boost-build set up, you cd to the ``bindings/python``
|
|
directory and invoke ``bjam`` with the apropriate settings. For the available
|
|
build variants, see `libtorrent build options`_.
|
|
|
|
.. _`libtorrent build options`: building.html#step-3-building-libtorrent
|
|
|
|
For example::
|
|
|
|
$ bjam dht-support=on release link=static
|
|
|
|
On Mac OS X, this will produce the following python module::
|
|
|
|
bin/darwin-4.0/release/dht-support-on/link-static/logging-none/threading-multi/libtorrent.so
|
|
|
|
using
|
|
=====
|
|
|
|
The python interface is nearly identical to the C++ interface. Please refer to
|
|
the `main library reference`_.
|
|
|
|
.. _`main library reference`: manual.html
|
|
|
|
For an example python program, see ``client.py`` in the ``bindings/python``
|
|
directory.
|
|
|
|
A very simple example usage of the module would be something like this::
|
|
|
|
import libtorrent as lt
|
|
import time
|
|
|
|
ses = lt.session()
|
|
ses.listen_on(6881, 6891)
|
|
|
|
e = lt.bdecode(open("test.torrent", 'rb').read())
|
|
info = lt.torrent_info(e)
|
|
|
|
h = ses.add_torrent(info, "./", compact_mode = True)
|
|
|
|
while (not h.is_seed()):
|
|
s = h.status()
|
|
|
|
state_str = ['queued', 'checking', 'connecting', 'downloading metadata', \
|
|
'downloading', 'finished', 'seeding', 'allocating']
|
|
print '%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s' % \
|
|
(s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \
|
|
s.num_peers, state_str[s.state])
|
|
|
|
time.sleep(1)
|
