= Skype plugin for BitlBee

== Status

[Wilmer van der Gaast (author of BitlBee)]

Okay, this exists now, with lots of thanks to vmiklos for his *excellent*
work!!

It's not in the main BitlBee and it'll never be for various reasons, but
because it's a plugin that shouldn't be a problem.
____

One day I browsed the BitlBee bugtracker and found
http://bugs.bitlbee.org/bitlbee/ticket/82[this] ticket. Then after a while I
returned and saw that it was still open. So I wrote it.

It's pretty stable, I use it for my daily work. Being a plug-in, no patching
is required, you can just install it after installing BitlBee itself.

NOTE: You will see that this implementation of the Skype plug-in still requires
a Skype instance to be running. This is because I'm not motivated to reverse
engineer Skype's
http://en.wikipedia.org/wiki/Skype_Protocol#Obfuscation_Layer[obfuscation
layer]. (Not mentioning that you should ask your lawyer about if it is legal or
not..)

== Requirements

* Skype >= 1.4.0.99. The latest version I've tested is 2.0.0.27.
* bitlbee >= 1.1.1dev. (This is the latest version I've tested, probably
  newer versions will work, too.)
* Skype4Py >= 0.9.28.7. Previous versions won't work due to API changes.
* Python >= 2.5. Skype4Py does not work with 2.4.
* pygobject

`bitlbee-skype` has been tested under Linux and Windows. Skype is available
under OSX, too, so it probably works, but this has not been tested.

== How to set it up

Before you start. The setup is the following: BitlBee can't connect directly to
Skype servers (the company's ones). It needs a running Skype client to do so.
In fact BitlBee will connect to `skyped` (a tcp server, provided in this
package) and `skyped` will connect to to your Skype client.

NOTE: The order is important. First you have to start Skype. Then `skyped` can
connect to it, finally BitlBee can connect to `skyped`. (In fact `skyped`
automatically reconnect if you restart Skype.)

- If you happen to be a happy Frugalware user, you can install the `bitlbee`
  and `bitlbee-skype` packages from
  http://ftp.frugalware.org/pub/other/people/vmiklos/bmf/[my repo].

- You need the BitlBee testing/development version:

----
$ wget http://get.bitlbee.org/src/bitlbee-1.1.1dev.tar.gz
$ tar xf bitlbee-1.1.1dev.tar.gz
$ cd bitlbee-1.1.1dev
----

NOTE: You no longer need additional patches, as of version 1.1.1dev.

- Now compile and install it:

----
$ ./configure
$ make
# make install install-dev
----

- Get the plugin code:

----
$ git clone git://vmiklos.hu/bitlbee-skype
----

(Or you can use the tarballs below, see the Changelog about what
features/bugfixes will you miss in this case).

NOTE: It doesn't matter where do you get it, it'll install the plugin to
`/usr/local` by default (that's the location where BitlBee searches for plugins
by default).

- Compile and install it:

----
$ cd bitlbee-skype
$ make prepare
$ ./configure
$ make
# make install
----

- Install http://skype4py.sourceforge.net/[Skype4Py].

(You may remember that previous versions of `skyped` did not require this
package. This because it now uses the X11 interface of Skype (because the
previously used `DBus` interface had
http://forum.skype.com/index.php?s=&showtopic=94545&view=findpost&p=431710[known
problems]), but I wanted to prevent a large code duplication from that project.
In addition it then no longer requires the `dbus-python` package, just
`pygobject`.)

- Edit `/usr/local/etc/skyped/skyped.conf`: adjust `username` and `password`. The
  `username` should be your Skype login and the `password` can be whatever you
  want, but you will have to specify that one when adding the Skype account to
  BitlBee (see later).

NOTE: Here, and later - `/usr/local/etc` can be different on your installation
if you used the `--sysconfdir` switch when running bitlbee-skype's `configure`.

- Generate the SSL pem files:

----
# cd /usr/local/etc/skyped
# openssl req -new -x509 -days 365 -nodes -config skyped.cnf -out skyped.cert.pem \
        -keyout skyped.key.pem
----

NOTE: Maybe you want to adjust the permissions in the `/usr/local/etc/skyped`
dir. For example make it readable by just your user.

- Start Skype and `skyped` (the tcp server):

----
$ skype
$ skyped
----

NOTE: You should run `skyped` on the same `X11` display, otherwise it won't be
able to connect to Skype!

- Start your `IRC` client, connect to BitlBee and add your account:

----
account add skype <user> <pass> localhost
----

<user> should be your Skype account name, <pass> should be the one you declared
in `skyped.conf`. If you want to run skyped on a remote machine, replace
`localhost` with the name of the machine.

== Setting up Skype in a VNC server (optional)

Optionally, if you want to run Skype on a server, you might want to setup up
a `VNC` server as well. I used `tightvnc` but probably other `VNC` servers will
work, too.

First run

----
$ vncpasswd ~/.vnc/passwd
----

and create a password. You will need it at least once.

Now create `~/.vnc/xstartup` with the following contents:

----
#!/bin/sh

sleep 1
skype &
sleep 5
skyped
----

Adjust the permissions:

----
$ chmod +x ~/.vnc/xstartup
----

Then start the server:

----
$ vncserver
----

Then connect to it, and set up Skype (username, password, enable auto-login, and
allow the `SkypeApiPythonShell` client when Skype asks about it).

Please be aware about that Skype has serious memory leak issues. After running
with for a few weeks it may eat >300 MB of memory. Just don't forget to restart
your VNC server regularly. (How ugly.)

== What works

- Download nicks and away statuses from Skype

- Noticing joins / parts while we're connected

- Sending messages

- Receiving messages

- Receiving away status changes

- `skyped` (the tcp daemon that is a gateway between Skype and tcp)

- Error handling when `skyped` is not running and when it exits

- Marking received messages as seen so that Skype won't say there are unread messages

- Adding / removing contacts

- Set away state when you do a `/away`.

- When you `account off`, Skype will set status to `Offline`

- When you `account on`, Skype will set status to `Online`

- Detect when somebody wants to add you and ask for confirmation

- Detect when somebody wants to transfer a file

- Group chat support:

  * Detect if we're invited

  * Send / receive group chat messages

  * Invite others (using `/invite <nick>`)

  * Part from group chats

  * Starting a group chat (using `/j #nick`)

- Topic changes in group chats:

  * Show the current topic (if any) on join

  * Notice when someone changes the topic

  * Support changing the topic using `/topic`

- Viewing the profile using the `info` command.

- Handling skype actions (when the `CHATMESSAGE` has `EMOTED` type)

- Setting your mood text using the `nick` command.

- Running Skype on a machine different to BitlBee is possible, the
  communication is encrypted.

== What needs to be done (aka. TODO)

- Add a question callback for calls.

- Notice if foo invites bar. Currently you can see only that bar joined.

- Public chats. See link:http://forum.skype.com/index.php?showtopic=98872[this
  forum thread], it is still unclear how could it be done for you to be able to
  `/join` to a public chat..

- Split skyped from the plugin, so that one could install just the relevant
  code if they are not running on the same machine.

== I would like to have support for ...

If something does not work and it's not in the TODO section, then please
contact me! Please also try the git version before reporting a bug, your
problem may be already fixed there.

In fact, of course, I wrote this documentation after figured out how to do this
setup, so maybe I left out some steps. If you needed 'any' additional tricks,
then it would be nice to include them here.
