** ABOUT **

SàT is a XMPP (Jabber) client, made on a daemon/frontends architecture. Its aim is not only to be an instant messaging client: SàT manage microblogging, file transfer, rich text edition, piping over XMPP, XMPP remote, etc.
In addition, SàT has been built with ethic in mind, a social contract show the main lines (see CONTRAT_SOCIAL or CONTRAT_SOCIAL_en). We have a lot of debates about the right way to do things, more on a social way than on a technical way (but consider technique too).

For the moment, the frontends are:

* primitivus: a console interface client, for screen lovers
* jp: the powerful command line toolkit.
* libervia: the web frontend. It's in a different package, check libervia on the wiki: http://wiki.goffi.org/wiki/Libervia
* bellaciao: a Qt frontend at an early development stage

other frontends planed in the near future:

* mobile frontends, fuse frontend, etc.


** HOW TO USE IT ? **

For installation instructions, please read the file "INSTALL". Note that SàT is available in several GNU/Linux distributions

A wiki is available online (http://wiki.goffi.org), in French and English so far (we would appreciate any help for other languages). You can also have a look at the bottom of this files (in contact section) for other available websites.


** MISC **

To use SàT, you need to have D-Bus daemon launched (http://www.freedesktop.org/wiki/Software/dbus/). If you use X Window, it should already be launched. If your are on a terminal environment without X11 (e.g. on a server) you may have to launch it. You can launch a daemon using the following command:
$ eval `dbus-launch --sh-syntax`

Be careful to use the same environment variables if you start a new session.

I personally use the following script to do that automatically:

--- /usr/local/bin/dbus-launch.sh ---
#!/bin/sh

DBUS_PATH="/tmp/.dbus.`whoami`"

if [ ! -e $DBUS_PATH ]; then
        dbus-launch --sh-syntax > $DBUS_PATH
        chmod 400 $DBUS_PATH
fi

cat $DBUS_PATH
--- end of /usr/local/bin/dbus-launch.sh ---

You can launch this script by putting at the end of your .zshrc (or whatever you're using):
eval `/usr/local/bin/dbus-launch.sh`

You can find Primitivus shortcuts on the wiki:

SàT is the acronym (yes another one :( ) in tribute to the song Salut à Toi from the Bérurier Noir band. I recommend also the excellent cover from Les Ogres de Barback.
jp stands for "Jabber coPy" or "JumP".
Primitivus is based on Urwid, and, according to their FAQ, "ur" is a German prefix for "ancestral or primal" (primitivus is a latin word).


** CREDIT **

A big big thank to the authors/contributors of...

proxy65:
SàT (plugin_xep_0065) use nearly all the code from proxy65 (http://code.google.com/p/proxy65/) which was coded by Dave Smith (2002-2004) and maintained by Fabio Forno (2007-2008).
As the original MIT licence allows, the code is reused and sub-licenced until GPL v3 to follow the rest of the code.

progressbar:
SàT (jp) use ProgressBar (http://pypi.python.org/pypi/progressbar/2.2), a class coded by Nilton Volpato which allow the textual representation of progression.

twisted:
SàT is heavily based on the twisted framework (http://twistedmatrix.com/trac/), a very great tool which offer a lot of protocols management. There are too many contributors to name them here, so take a look on the website :).

wokkel:
SàT use a library with high level enhancements on top of twisted, which is called wokkel (http://wokkel.ik.nu). Lot of thanks to Ralph Meijer and all other contributors.

Urwid:
Primitivus is based on Urwid (http://excess.org/urwid/) which saved me a lot of time. It's really a great library to easily make a sophisticated interface.

Pyjamas:
Libervia is built with a Pyjamas (http://pyjs.org), a Google Web Toolkit port for python, including Python to Javascript compiler, and Pyjamas Desktop which allow to execute the same application on the desktop or through a browser. It's really an amazing tool.

lxml(http://lxml.de/):
this powerful and efficient XML parsing module is used sometimes to replace Twisted internal tools: its API is handy, and it have some features like evil content cleaning.

pillow(https://python-pillow.github.io/):
This image manipulation module is used for avatars

txJSON-RPC:
Libervia use txJSON-RPC (https://launchpad.net/txjsonrpc), a twisted library to communicate with the browser's javascript throught JSON-RPC

Mutagen:
Mutagen (https://bitbucket.org/lazka/mutagen) is an audio metadata handling library, it's used by the radiocol plugin.

Python OTR (http://python-otr.pentabarf.de), PyCrypto (https://www.dlitz.net/software/pycrypto) and pyOpenSSL(https://github.com/pyca/pyopenssl):
Used for cryptography

otr.js and its dependencies Big Integer Library, CryptoJS, EventEmitter:
Libervia frontend uses otr.js and its dependencies:
    - otr.js was coded by Arlo Breault (2014) and is released under the Mozilla Public License Version 2.0
    - Big Integer Library was coded by Leemon Baird (2000-2013) and is in the public domain
    - CryptoJS was coded by Jeff Mott (2009-2013) and is released under the MIT licence
    - EventEmitter was coded by Oliver Caldwell (2011-2013) and is released under the MIT licence
As the original licences allow, the code is reused and sub-licenced until GPL v3 to follow the rest of the code.

mardown (https://pythonhosted.org/Markdown/) and html2text (https://pypi.python.org/pypi/html2text/2015.6.21):
both are used for syntaxes conversions

Jinja2 (http://jinja.pocoo.org/):
a poweful template engine for Python that we use for designing Libervia's static blog pages

miniupnp (http://miniupnp.free.fr/):
this UPnP-IGD implementation is used to facilitate P2P sessions

netifaces (https://pypi.python.org/pypi/netifaces):
when available, this module is used to detect local IPs

pictures found in the sat_media repository and used by SàT and Libervia:
Please read the credits and licence information that are given in the README and COPYING files for each work: http://repos.goffi.org/sat_media/file

the powerfull ImageMagick (http://www.imagemagick.org/) is used by the script written to split the previously named picture.

PyXDF (http://freedesktop.org/wiki/Software/pyxdg):
Used to follow FreeDesktop XDG standards

A special thank to people working on XMPP standards, libre standards are the way to go !

and the others:
and of course, nothing would be possible without Python (http://www.python.org/), GNU and the Free Software Foundation (http://www.gnu.org, http://www.fsf.org/), the Linux Kernel (http://www.kernel.org/), and the coder of the tools I use like Vim (http://www.vim.org/), Mercurial (http://www.selenic.com/mercurial/wiki/), or all the KDE stuff (http://www.kde.org/ and of course http://amarok.kde.org/), and also XFCE (http://www.xfce.org), etc. Thanks thanks thanks, thanks to everybody in the Free (Libre) chain for making a part of the dream.

If I forgot any credit (and I probably have), please contact me (mail below) to fix it.
