Folks 0.1.17 includes a migration tool

The latest release of Folks, 0.1.17, includes a new folks-import tool to import meta-contacts data from Pidgin. So if Pidgin knows frank.reynolds@example.com and the_penguin@example.org are the same person, folks-import will catch Empathy up-to-speed.

Now would be a good time to double-check your "Excuses for not switching to Empathy" list.

Thanks to Philip for writing the tool.

We've also got a nearly-working Pidgin backend to let Empathy support this functionality native in its Import wizard, but it was too late in the Gnome 2.32 release cycle to squeeze it in.

And farther into the future, Folks should perform reasonably aggressive auto-linking, which should make even semi-automated linking like this unnecessary.

Empathy hacking setup

Edit: Good News, Everyone! Sjoerd pointed out that the D-Bus fiddling in this post is unnecessary (as I'd hoped, but hadn't been able to manage). I mistook bgo#628738 for misconfiguration on my system.

So, this "guide" can be shortened to:

  1. create a new user (empathy-dev)

  2. install jhbuild

  3. jhbuild build empathy

  4. echo "export PATH=/opt/gnome/sbin:/opt/gnome/bin:$PATH" >> /home/empathy-dev/.bashrc

  5. echo "export XDG_DATA_DIRS=/opt/gnome/share:/usr/share:$XDG_DATA_DIRS" >> /home/empathy-dev/.bashrc

  6. slogin -X empathy-dev@localhost

  7. empathy

In order to do development on Empathy, I've created another user on my system (creatively named "empathy-dev") and run my development versions of programs, libraries, and services through this user. This has a couple major benefits:

  • zero downtime - I frequently restart Empathy during development. Running the default system version of Empathy as my regular user means I can stay online as I develop.
  • fault isolation - if I horribly break my development environment (eg, the bleeding-edge libraries I depend upon introduce major bugs), it doesn't affect my system stability

It was somewhat non-trivial to create a good setup, so I thought other people might find this handy.

Throughout this short guide, I use references to /opt/gnome, which is the standard jhbuild $PREFIX. So substitute your development $PREFIX as necessary. I make a point to not use the standard Unix development $PREFIX (/usr/local) so that my regular user doesn't run the development programs or libraries (for stability and sanity; see below).


Skip the remaining steps this guide - it's needlessly complicated


First, we need to set up a few bits and pieces so your shell and D-Bus know where to find the development programs and config. I use a fairly standard D-Bus local session config file.

The important (and only non-standard, I think) part is:

/opt/gnome/share/dbus-1/services

This allows the programs installed in our $PREFIX to launch necessary services (eg, Mission Control, the Telepathy Connection Managers) through D-Bus activation.

Download this file, adjust it as necessary, and put it in /home/empathy-dev/.dbus-1

Add this to the end of your development user's .bashrc:

export PATH=/opt/gnome/sbin:/opt/gnome/bin:$PATH

# let programs find any new icons, default config files, etc.
export XDG_DATA_DIRS=/opt/gnome/share:/usr/share:$XDG_DATA_DIRS

# automatically start a D-Bus session bus
alias dbus-setup="dbus-launch --config-file=$HOME/.dbus-1/session-local.conf"
session_setup=$(dbus-setup)
if [ $? -eq 0 ]; then
echo "\nSet up D-Bus session for $USER:";
echo $session_setup
eval export $session_setup
else
echo "\nFAILED setting up D-Bus session for $USER";
fi

Once you've got that set up, it's easy to launch the development version of Empathy as a different user:

slogin -X empathy-dev@localhost

Then, just run empathy and marvel at its independence from your main user's instance. However, if you haven't installed a newer version of empathy in $PREFIX/bin, this will just fall back to your system-installed version.

Fix this by setting up jhbuild and running "jhbuild build empathy". Find something to do for about 20 minutes. When you come back, if our dependencies haven't failed to build, you'll be able to run the latest version of Empathy as empathy-dev, without getting in the way of your system user.

Happy hacking!

dbus-launch will keep the dbus-daemon (and anything it activates) running by default after your development user logs out. There's a --exit-with-session option, but for some reason, if I use it here, about 30% of my keystrokes at the shell don't arrive. I'm flabbergasted, but it seemed completely tied to this dbus-launch option (I tried several times each way).

Meta-contacts in Empathy (and beyond!)

We've finally closed Gnome Bug #460647 (Empathy: Support metacontacts)!

Let's get right to the pictures:

metacontacts-linking-dialog

This is our "Link Contacts" dialog. Selecting a number of contacts on the left side designates which contacts will be included in the Individual (read: meta-contact) at right.

We currently auto-link contacts with the same service ID (foo@example.org) contained in multiple accounts. In the future, we're going to push as much into auto-linking as possible. My goal is that most users would never need to use this dialog. Until then, this dialog is how you designate meta-contacts in Empathy.

metacontacts-edit-dialog

If you accidentally link together contacts you didn't mean to, you can simply open the Individual's info dialog and hit Unlink to start over.

metacontacts-persona-menus

One of the first benefits of meta-contacts is pulling together multiple modes of contact for a person into a single place. So if you've got a friend with separate work and personal IM, you can be an upstanding citizen and only send funny cat pictures to their personal IM address. (If they sign on to both at work, at least you tried your best).

We've kept the 1-click Chat/Audio Call/Send File/etc. actions for the (I think, more-common) case that you just want to communicate and you don't care about the specifics. This just uses any valid (ie, online) account for that Individual.

Thanks

This meta-contacts functionality is all possible thanks to the Folks project. It's a collection of libraries (so far, all distributed together) that collect contact information through various backends (Telepathy so far; many more to come) and aggregate Individuals (ie, People). Empathy was our starting point, but we really plan to integrate very well into the Gnome desktop and beyond. Think: typing -Alice- to start a chat with Alice through the Gnome Shell.

I'll discuss Folks in greater detail in future posts.

I'd like to thank my colleagues Philip "code factory" Withnall for helping with Folks development/Empathy integration and Empathy maintainer Guillaume Desmottes for letting us know exactly what we broke in each commit. And, of course, a special thanks to our employer, Collabora, for sponsoring us to work on this full-time.

Try it now!

Since you're no doubt very excited about these new features in Empathy, you can use them Right Now™ in version 2.31.91 (also coming to Debian experimental shortly). Be sure to file any and all bugs you run into, so this will be as solid a stable release as any other!

If software bugs have you leaping onto the nearest elevated furniture, no problem -- Empathy will, of course, by included in Gnome 2.32, coming to a friendly Linux distribution near you!

Empathy accounts work for MeeGo (and free desktops everywhere)

I'd like to congratulate the MeeGo team on shipping MeeGo 1.0 for Netbooks! It's nice to see user-experience-driven design on Linux (where it tends to be conspicuously absent), shipping in a complete product. It really shows, too -- the UI is extremely responsive and it makes the whole experience a joy.

Thanks to Intel hiring Collabora for some MeeGo work, I made a few contributions to the distro some months back. Some were evolution data server code clean-up, adding tests, etc. For the interesting, user-visible changes (that I didn't work on), see Michael Meeks's post about Evolution in MeeGo.

But the more visible contributions were to Empathy's account settings. Originally, Empathy's "first-run" account setup wizard and accounts settings dialog were in the same process as Empathy. This meant you had to launch Empathy before you could edit your accounts, which is a little awkward if you're another application. Telepathy accounts aren't Empathy-specific, so it makes sense that the dialog be independent (though it still lives in the Empathy source tree).

Empathy account wizard in MeeGo 1.0

Thomas Wood's unified Control Center work appears MeeGo, and I adapted the Empathy accounts dialog to embed in it. The screenshot is fairly self-explanatory. When you access the accounts from the Control Center, you get a nice, full-screen version of the dialog:

Michael Meeks mentioned how small most netbook screens are. When you also factor in the MeeGo panel at the top of the screen, you can get situations where you need scrolling (but didn't on the full-sized desktop). So we added a scrollable view to the accounts dialog (to fit the full content of the Advanced section for protocols with a bevy of bells and whistles):

Since the actual dialog content is the same whether it's embedded or not, the same functionality works when it's stand-alone as well:

And because the MeeGo team understands open source software, these features were developed out in the open and have been included in the last few releases of Empathy. So if you don't have them already, you will soon!
