Various news: what happend durring summer

It's been a while since I blogged about something. So here's a bunch of things I've done the last month.

Holidays

Well, I've been in holidays one week. :-P

awesome

There have been a huge number of changes between 3.3 (released in June) and 3.4 (almost relesed). I wrote a small but very useful object layer on top of Lua, which adds a class/object system a bit like gobject. I've also replaced all the hooks by per-class/object signals. Finally, the awesome Lua basement are cleaner than they were before, and the extendability is improved. How nice.

We're trying to release 3.4 (rc2 should be out soon), but the development pace is a bit slower than a year before. We're basically almost 2 months late on what was our previous release rate. Not a big deal however.

I've started working on 3.5 slowly. It gonna get amazing new features too. :-)

Google Summer Of Code 2009

I've mentored Mariusz Ceier on XCB GSoC. He worked on adding Xinput2 and XKB extensions. And he managed to do this. His work should be imported ASAP, the discussion has started on XCB maling list last week.

In exchange, Google offered me (and to every mentor) an awful blue t-shirt! Thanks Google! :-P

awesome survey 2009

I've created a small survey about awesome. I hope that will allow us to enhance our lovely software. :-)

awesome: larger open-source team than LXCDE one of the largest open-source teams in the world

I just found this blog post on LXDE blog while reading LWN.net.

It made me smile because that's what Ohloh says for awesome:

Over the past twelve months, 70 developers contributed new code to awesome. This is one of the largest open-source teams in the world, and is in the top 2% of all project teams on Ohloh. For this measurement, Ohloh considered only recent changes to the code. Over the entire history of the project, 99 developers have contributed.

So awesome project is roughly twice bigger than LXDE. Impressive! ;-)

I will tile your face

Whoever defines awesome as a tiling window manager should think twice before saying such a thing.

In that case, I'll change some software description also:

  • Firefox: FTP browser based on Mozilla
  • Thunderbird: Software to send mails
  • OpenOffice.org: Text editor
  • GNOME: GTK based game collections
  • Python: Zope language

A software being able to do something do not mean that the software is meant to be something. You can browse FTP servers with Firefox, but it's not mainly a FTP browser. You can send mails with Thunderbird, but it's not mainly what it does. You can edit text with OOo, but also do some spreadsheets stuff. You can play games with GNOME, but you can also do plenty of others stuff. You can write Zope and its applications with Python, but that does not mean Python is Zope.

So you can definitively do tiling window management with awesome, but you can do a lot more. It's not its primary feature. So it's not a tiling window manager.

awesome is bloated

That's just something I hear from time to time, and I love it so much.

Fluxbox: 65010 SLOC

Metacity: 62923 SLOC

Openbox: 36336 SLOC

awesome: 19207 SLOC

Taking the other direction

I've started to develop awesome more than 18 months ago, and somehow I feel it's time to stop a bit and think where we come from and where we are going to.

The motivation

I never though I'd be written a window manager one day. That seems kinda stupid when you see how many window manager there's around.

As many people, I've tested and have been using tons of window manager: Window Maker, Fluxbox, etc.

In August 2007, I was using fvwm since 2004 and was quite happy with it. I used the famous fvwm crystal as a configuration starter and then rewrote lots of stuff. Digging into fvwm configuration files was boring, and since I'm lazy, I never really configured it to fit entirely my needs.

The thing is that, in July 2007, my workstation died. I bought a new one based on the amd64 architecture. Too bad, with this new box, fvwm decided that it will not longer runs and was segfaulting almost every time I logged in.

I was really upset. Another failure in the window manager world. So I decided to get the yearly ride of testing many window managers. I went on the no more developed stuff like the *boxes, ion3, etc… but well, I did not like them, there were not powerful enough, too bugged or upstream was insane.

Then I found xmonad. The Haskell configuration file format made my cry. I did not want to learn Haskell, it seemed too obfuscated to me. At that time it was even not packaged for Debian, so I gave up. But I found dwm in the meantime, and I loved it. It was simple, and the source code was almost understandable and easy to hack.

I subscribed to the dwm mailing-list, in order to participate to its development, etc… But I got really disappointed. No patch were welcome and the development seemed to be almost finish in this sight. People patches were lying around, but no one really care. Each user was managing its own set of patches.

That's not what I learnt and what I love in free software. So, as many users, I began to maintain my patches in my corner. But I began to have more ideas…

The jdwm

I just added a 'j' in front of dwm and started to hack it days and nights to add many feature I missed, like multi-head, etc… On 5th September 2007, I created a git repository to host my code.

That's gonna be… awesome.

Five days later, on 10th September, I finally found a name for my new pet: awesome, borrowed from Barney Stinson who heavily uses and abuses this word.

The 1.x branch

The first releases until December were noted 1.x. It was just a better dwm with a simple flat configuration file.. The configuration file used libconfig, but it was a very poor choice. And I was not able to put in into Debian because of name clash.

The 2.x branch

The 2.x branch came in January 2008 with a brand new configuration file format based on libconfuse, which was a bit more powerful. Many concepts and features that have been added in this branch are still used in the current 3.x branch.

At this time, between December 2007 and April 2008, the community was growing smoothly.

But as I said, awesome 2 was based on a flat configuration file. That raised a problem very soon: users expectation were growing and the development team (me and a couple of regular contributors) was unable to cope with them.

One of the event that started to change my mind was the support for titlebars.

When I've added titlebar support, it was minimal. It was on top of a window, with the window title. Dot. Then I've started to add a lot of options, like the application icon drawing, the position (left, right, bottom) etc.

And then users started to ask for more, like: "add titlebar on windows only when the window is floating".

That's ok, but that's complicated: that's again another option to do some stuff conditionally. And then, why don't add titlebar on windows when <insert random events here>?

The 3.x branch

Why

At that time, around April 2008, I'd totally stopped development. I was trying to find a solution which was simple and powerful. But after 2 weeks of thinking, I was not able to find anything else than: use a real language for configuration.

So, I've started prototyping awesome 3 using Lua. The choice was not obvious, and despite the problem Lua might suffer, it's one of the easiest language to integrate into an existing application. There's still a video of a first version here.

But, let's go a little back: in January 2008, Arnaud Fontaine contacted me because he was interested to use awesome as one of its school project. He decided to port awesome from Xlib to XCB, a modern asynchronous X library.

His work took some time, but in May 2008, Arnaud did finished to port git master version of awesome to use XCB.

Consequently, I decided to start a new major branch, using XCB instead of Xlib (no change for users in this regard) and Lua instead of our previous flat configuration file format.

Development

It took me a while to get from here to there, but in September 2008, it was ready. We had a simple Lua API, and the XCB port was working perfectly.

It took us some time to release and have something totally working, because we had to work on XCB and contribute back to the project. It was really not ready to use by an application, but we did great work in this area and it's now really fine.

We're still here

Releases continue to happens, 3.1 around December 2008, and 3.2 around March 2009. 3.3 should be here in June.

One of the drawback we had, is that we moved many stuff from C to Lua. Why? Because writing things in Lua is quicker and easier to maintain than C, and makes thing more configurable for the user.

For example, the layout algorithm used to organize window were written in C until 3.2 came out. At that time, users had no choice than using a set of predefined layout to organize their windows.

Starting with 3.2, if they have minimal knowledge about geometry, they can start writing a layout function organising windows on the screen.

But this kind of API changes was a bit rough for users, since they had to port some part of their configuration file to the new API. The thing is that the project was still a teenager at that time, not really knowing were it will go. But I'm happy to announce that API breakage are more and more rare (so far only one minor between 3.2 and 3.3), and anyway always for the Good.

But I admit that it built a bad reputation around awesome 3.x during its first month of existence.

Future direction

I am currently working on 3.3 development. We have still many things to do. Time passing, we get more idea, and more users. And more users bring more ideas. We also have many more contributors, and some guys are even taking maintainer-ship of some code area.

Conclusion

My post title is "Taking the other direction" because I feel this way.

I've got that feeling that some approaches in projects like GNOME are sometimes bad. Please don't misread me, I know we are not playing in the same yard.

When adding a key shortcut for starting an application makes you dig into gconf, I wonder how this is a win for the user.

Well, it's probably a win for the end-user, but I surely am not one of them. And I don't intend to target them with my software, anyway.

And now, when I hear things like GNOME 3.0 and the "desktop shell" approach, that makes me smile. Guys, it was time, but have luck. What I see from here, is that any desktop control interface is wrong somehow, and that there's no approach that can fulfill all users wishes.

I think that we, the awesome development team (no pun intended) took the direction of building a frame-work window manager rather than a solution written in marble.

We (partially) solved the issue of UI ergonomic by not writing one and allowing the user to write his own. I don't say that's easy to do for most of users, but it's doable.

And I think it's worth it: I use window managers since I use Linux, around 1998. If something like awesome came 5 years ago, I'd be using it so far, because you can write Fluxbox or WindowMaker using awesome in a hundred of Lua code. And you can write your own version of it. And it starts in less than 3 seconds, supporting almost all standard desktop specification (ICCCM, EWMH, XDG, system tray, message notification, D-Bus, etc), whereas many of the window mangers do not.

You can even write and play space invaders.

Finally, I'm happy about the the road we took so far, and hope we will continue into that direction. The rants I read about our project are not that big, compared to the kudos we received.

Still working!

Well, I'm not dead buddies. I was overbooked.

Last weeks have been a bit busy for me. I've also been on holidays, so I gave up on computers stuff a bit.

awesome

Big news: awesome 3.2 has been released some weeks ago, and seems to be a success so far. We're working on the new 3.3 release, which will have some new sexy feature you'll love. More on that later.

Debian

I've uploaded a new awesome-extra package with third party modules such as shifty or wicked.

startup-notification

I just managed to be added in the startup-notification group at Freedesktop. I moved the CVS repository to git and merged my set of XCB patches.

OpenOffice is better as a pager than as a text processor

Since several month, awesome users have reported a bug with OpenOffice.org. When using OOo and clicking on a menu, or using the mouse wheel to read a document, the currently selected tag (desktop) will change automagically to another one.

I've digged into awesome and found that awesome received a _NET_CURRENT_DESKTOP request. As defined by EWMH, this kind of request are sent by a pager to change the active desktop.

That was weird. Nobody is using a pager here. So, I just kicked my gdb out, attached it to OOo, breaking on XSendEvent call. And I got it:

Breakpoint 1, XSendEvent (dpy=0x1a00080, w=483, propagate=0, event_mask=1572864, event=0x7fff1fd70d70)

I started digging more into the code, and this is what I finally found in salframe.cxx:

       // #i45160# switch to desktop where a dialog with parent will appear 
       if( mpParent && mpParent->m_nWorkArea != m_nWorkArea ) 
           GetDisplay()->getWMAdaptor()->switchToWorkArea( mpParent->m_nWorkArea );

Beautiful! It even has a comment with a IssueZilla bug number. Let's go and see where it comes from.

After 10 minutes of research to find that fucking IZ, I finally found the link to the issue #45160. The bug is IMHO not related to OOo but to a window manager doing poor job.

I've found that an awesome user already reported an bug… err, wait, I mean an issue as issue #96684 (remember there's no bug in OOo, only issues) and I commented about it.

UPDATE: It seems OOo developers have agreed to fix that bug eventually.

What's new in awesome 3.2

We're working since several month on awesome 3.2, and here is what you'll get soon:

  • By wibox X cursor;
  • New mousegrabber infrastructure;
  • Client move with mouse is now in Lua;
  • New D-Bus hooks; you can also watch D-Bus events to get information like the song played in Audacious, or things like that;
  • naughty (notification library) now supports notification via D-Bus, following standard notification protocol;
  • Layout code moved to Lua;
  • Client gets a new mouse_leave hook;
  • Floating state is now handled on Lua side;
  • Windows groups are handled and exported to Lua API;
  • Various awesome markups have been removed in favor of widgets properties (simpler);
  • Shadow support has been removed (too buggy);
  • Add new telak module (draw image from the Web on your root window);
  • Add mouse move code for wiboxes;
  • Add functions to move clients with mouse to tags via the taglist;
  • Add support for key release events in keybindings;
  • Add support for input faking into client via XTest extension;
  • Add support for X selection retrieval (clipboard);
  • Add support for real transparency attribute on wiboxes;
  • Replace tile layout by a new layout (originally called 'vile') which supports resizing of slaves clients.

We've done a nice job. :-) Thanks to all contributors! See you soon for the first release candidate version…

startup-notification port to XCB

Since Tuesday, I've begun to work on XCB portage of the startup-notification library.

I've just completed the job, and send a bunch of patches to the XDG mailing list. My work is available in my startup-notification git repository.

If the patches are merged, which I don't doubt, I'll be able to use this lib into awesome, which would be nice step to the Freedesktop standard compliance I like to make.

telak in awesome

Some years ago I wrote a little tool called telak in order to display remote images on my wallpaper and have them updated regularly.

Yesterday, as a challenge, I rewrote this as an awesome module, in Lua using wget. I simply used a wibox and a widget from awesome API to display the images.

It's called telak, as the original, and is in the awesome next git branch, which will be the 3.2 version of my favorite window manager.

Implementing desktop notification in awesome

Since version 3.1, awesome is bundled with naughty, a notification library which allow to raise pop-up in front of the screen to display information you chose. A sort of notification-daemon, but not plugged into D-Bus.

Last days I've began to work on awesome 3.2 (aka the 'next' branch in awesome repository). I've started to chat with Leon Winter on IRC about the possibility to implement notification specifications into awesome.

awesome had since version 3.0 a very light D-Bus support, since it only allowed to evaluate Lua remotely, without getting an answer anyway.

I've hacked it so now there's a D-Bus hook, which is called upon a D-Bus message received. This, plus the possibility to return various data type (not all are implemented as of this day) allowed Leon to enhance the naughty library and to add support for a primary notification support.

I just have to add more D-Bus data type support, and we may be able to support all the specs, with icons support, etc.

awesome 3.1: more changes

A lazy morning again, so you'll enjoy another short list of changes in the upcoming awesome 3.1 (first one is still here):

  • Text can now be spread across multiple lines, using pango ability to wrap text;
  • New full screen layout;
  • awful.clients.swap.bydirection function;
  • Images get crop_and_scale() method;
  • New module: invaders, a space invader game;
  • New module: naughty, notification module (like GNOME's notification-daemon);
  • More hooks: "clients" for client list changes, "tags" for tag list changes and "tagged" for client's tag list changes;
  • Wiboxes's widgets can now be composed of arrays of arrays, specifying a DAG structure, unless of a simple array. A reference is kept to it so it can be retrieved later. Any array can be modified with awesome being notified using a proxy table system.
  • Taglist and tasklist widgets are gone from core and are now written in Lua, using the above system.

Not too much changes, I've spent something like a week thinking and writing the 2 last points. I've now a bunch of things to finish and I think we'll go for a RC release in something like a couple of weeks.

Space invaders for awesome

I was sure it will be possible.

With current awesome git version it's possible to run a space invaders game.

Space invaders

With only 380 lines of Lua.

Is there any window manager capable of doing this ? ;-) And don't say it's useless!

Thanks to Gregor "farhaven" Best for wasting his time with that.

awesome 3 released

I just released the final version of awesome 3.

I'm very happy to see all this work (6 months, over 1K patchset) and time spent on this piece of code being wide used and much appreciated. This last months were amazing and very exciting.

Thanks everyone for using it or contributing to it. You rock (too).

Let's go for awesome 3.1 now…

xcb-util 0.3.0 released

I just released XCB util and announced on XCB xorg-announce lists at Freedesktop.

This version has seen some of the modules totally rewritten, like ICCCM, event, reply or property. It also has a lot more documentation than previous, so I've set up doxygen documentation online.

It was the last step before releasing awesome 3 final… hm hm.

mercredi, septembre 10 2008

Working on…

I've been quite busy last weeks, between real life and awesome stuff.

awesome 3.0 final release is getting closer. No more release candidate version should be expected since there's only 9 small patches into master from rc6. Final release should be out real soon now, before the end of the month. Also, the next branch already contains already nice stuff for the upcoming 3.1 version.

I've done some grunt work on XCB also, pushing other patches and fixing padding stuff in XML protocol description. This was very boring, but well, had to be done, so… I did it.

That's all for now. Stay tuned.
