Parole 0.4.0 is out!

A new awesome release of the Parole media player for Xfce is out and ships all the hard work of Sean Davis and Simon Steinbeiss.

Sean wrote an extensive description of this new release on his blog, with tons of screenshots. As stated there, do not hesitate to give them feedback on this new release and to file any issue you may have on the Xfce Bugzilla.

Here is a screenshot of the new very nice main view while playing an audio file:

Parole 0.4.0

Congratulations to Sean and Simon for this excellent work!

Xfce4-terminal 0.6.x keyboard shortcuts

A lot of users seem to be wondering how to edit keyboard shortcuts in xfce4-terminal 0.6.x. The built-in shortcut editor is indeed gone and the application now uses editable GTK+ accelerators like other GTK+ applications. This is more consistent and allows to drop the exo dependency which makes the application lighter.

The FAQ of the Xfce documentation has a guide on how to edit GTK+ accelerators of xfce4-terminal. You'll get your custom shortcuts back in no time!

PS: xfce4-terminal 0.6.1 is out and has a killer "drop-down" mode ala guake / tilda. See Nick's Google+ page for screenshots.

Work in progress to improve keyboard shortcuts in Xfce

Long time no blog! I started to hack again last week with the goal of improving keyboard shortcuts handling in Xfce. I touched that during the Xfce 4.10 cycle and this unfortunately seem to have introduced a bunch of bugs that I'm now trying to resolve. I also took this opportunity to try to overhaul the UI and make it more understandable.

This code is available in the jeromeg/keyboard-shortcuts branches of xfwm4, libxfce4ui and xfce4-settings on the Xfce Git server. Some improvements are still planned but most of what I was planning is already implemented.

Here is a list of reported bugs which should be fixed once I merge this:

A brief summary: shortcuts now work when Caps Lock is on, shortcuts using Shift or the numeric keypad are handled correctly, a bunch of regressions are fixed, conflict handling is now more reliable and the UI should be better.

Regarding keyboard shortcuts bugs, keyboard shortcuts not working correctly after a reboot or not work working in some other cases seem to occur because of a "wrong" shortcut database often caused by a problem in the migration script in Xfce 4.6. In that case, the easier way to fix this seems to be to revert all keyboard shortcuts to default (in xfwm4-settings and xfce4-keyboard-settings) and to rebind them using the dialogs.

If you know what you are doing, it would be useful if you could test those changes and report me by mail any remaining issues. Suggestions for improvements are also welcome.

How to start contributing to Xfce or any other open source project

It’s been a while since I’ve updated this website and even longer since I’ve written anything useful. But since I’ve received a couple of mails from people looking to contribute to Xfce recently, I thought I’d share some “wisdom” acquired over the past few years while working on Xfce and doing a lot of community work. My thoughts are not limited to Xfce and will apply to a lot of other projects out there as well.

Here’s the bitter truth for those looking for some quick pointers to start contributing to Xfce: you’ll have to find out yourself.

The reason is not that we are lazy or wouldn’t welcome your contributions. In fact, the reason, I believe, is very simple: you will be more excited, motivated and, ultimate, be more successful if you work on something that interests you. We can help you in making the decision what to invest your time in easier, e.g. by listing projects, features or issues that we or our users consider worth working on. Some projects do this very visibly (e.g. through bounties). In Xfce, this information is hidden in the depths of the wiki. Here are a few links that you may find interesting:

Clearly, the above information could be more visible. There could be a prominent link on the Xfce website to a well-maintained and up-to-date list. Would that help people? Maybe.

Perhaps it is a good thing that the information isn’t just one click away. Open source projects have always been about scratching your own itch. This is how I got involved in everything I’ve done over the years. this approach is reflected by what people do and sometimes even by how companies make money. Thinking about it now, it is a concept deeply rooted in the evolution of mankind (think: the invention and improvement of tools, industrialisation and all that shit).

So: scratch your own itch.

If you want to start contributing to a project, try this exercise:

  • Look at the project, think about what you don’t like or what you feel could be improved
  • Try to collect information on what pieces are involved in e.g. the feature you’re missing or the bug you’ve spotted
  • Try to find the place where you could try adding your feature or fixing your bug
  • Ask whether developers are interested in the feature or look at whether there already is an item for your issue in the bug tracker
  • The rest is communication and coding

It’s not a fast path because you might not be able to contribute something of great value in the beginning. But if you’re dedicated, have enough spare time to make a difference and are keen on improving things step by step, you might eventually reach a point where you take over responsibility for more and more exciting or important tasks.

Good luck!

Vim and Vala

I once wrote a quick note about Vala and Vim (or Vim and Vala) and the use of the Tag List plugin. Here is a clean post about these two beasts.

Vim — probably the best editor out there, at least always after trying out different editors I end up with Vim — has great plugins. However there is a lack of support for the Vala language. So here are two basic add-ins to include in the Vim editor.

Vala syntax

First there is no syntax color for this language. A quick fix is to use the C# syntax with the command :set filetype=cs. That works but is not ideal, ideal is to install a vim.syntax file, and there is one available on this GNOME Live! page.

First download the file from this page and save it under ~/.vim/syntax. Next at the following lines to your ~/.vimrc file:
" Filetypes
augroup filetypedetect
au! BufRead,BufNewFile *.vala,*.vapi setfiletype vala
augroup END

augroup vala
autocmd BufRead *.vala,*.vapi set tw=100 efm=%f:%1.%c-%[%^:]%#:\ %t%[%^:]%#:\ %m
augroup END

Tag List

Tag List is a powerful plugin that lets you explore classes or functions from a source file, also called a source code browser. The installation steps are simple, they are also available bellow, and again to get it working with Vim there is a small hack to include inside the ~/.vimrc file.

First download the latest version of taglist from this page. Than uncompress the archive with, for example, the command line:
unzip -x taglist_45.zip -d $HOME/.vim/
Than go inside ~/.vim/doc, run Vim and inside Vim execute the command :helptags .:
cd ~/.vim/doc
vim
:helptags .
Finally add the following lines inside ~/.vimrc:
" Work-around Tag List for Vala
let tlist_vala_settings='c#;d:macro;t:typedef;n:namespace;c:class;'.
\ 'E:event;g:enum;s:struct;i:interface;'.
\ 'p:properties;m:method'

Now Vim is ready for Vala, and it's possible to browse source code by typing the command :TListToggle.

Questions after the 4.10 release

A short post to answerer some questions I’ve ready in comments on the 4.10 release news across the internet. If you have more questions, let me know in the comments and I’ll try to answer them.

A new stable release after 16 months? And no 4.8.1 release…

This is because Xfce has a different release model than for example GNOME or KDE when it comes to stable releases. Because of the limited team of developers we want to spend the least time possible on releasing packages. Big stable releases like other desktops do consume a lot of time, even with the small-ish amount of core packages in Xfce.

Therefore after 4.6 the following was decided: we only do 4 big releases (3 preview releases and 1 stable release) and after that only stable releases for individual packages. So the desktop version is 4.10 (notice the lacking micro-number), individual components could have higher 4.10.x numbers.

As an example, the last 4.8 stable release of xfce4-dev-tools is 4.8.0, the same as in the 4.8 fat-tarball release. The latest 4.8 release of xfce4-panel is 4.8.6 (6 stable releases after 4.8.0, which was in the 4.8 fat-tarball).

We know this is harder for starting users, who prefer to grab 1 tarball with all the latest versions, but instead need to crawl through /src/xfce and need to find the latest version. For distributions this is a lot easier: packagers are subscribed to the xfce-announce mailing list or peek identi.ca and once in a while they need to update 1 of the packages.

Nonetheless this is still a point where we can improve so I’ll see if I can provide more information on the website (announcements and links to the latest package versions).

4.10 only had 2 preview releases, because no critical bugs appeared and translations were in a good shape. Enough reasons for me to skip pre3 and release 4.10 instead.

Online Documentation Wiki

Just to be clear about this: we understand online docs are not a solution, but it was the best we could do in a short time. Hopefully the wiki-based setup will attract more contributors (who previously feared docbook or mallard, yes we tried that too) and lead to a complete set of documentation . When we feel satisfied with the content of the wiki we’ll look into a “wiki snapshot” for offline usage and ship that in an xfce4-docs package.

Gtk3

First 2 things: no Xfce 4.10 is not using gtk3, only the gtk-xfce-engine theme engine supports gtk3. Secondly we will discuss if Xfce 4.12 will be ported to gtk3. I’ll explain the latter:

Technically gtk3 is nothing different then gtk2 when it comes to programming. The hard parts are porting of some custom widgets (drawing and size allocation), replacements of some deprecated symbols and link to gtk3 libs. All things a user is not going to notice if we do it right.

Gtk3 is also not faster than gtk2, maybe there are some areas were it got a bit faster, but so there are areas where performance decreased a bit. Nothing shocking here.

An issue I’m aware of is theming issues in gtk3. From what I understand this changed back and forward in gtk 3.0, 3.2 and 3.4. So we need to decide which version we require to get this working consistently, because people will complain if only the Raleigh theme can be used :).

From the Xfce point of view there is (again) the resource problem for porting all plugins, because if for example the panel is ported to gtk3, also the plugins need to be ported. Not all goodies are maintained, but usually they work and distros can compile them. If in 4.12 suddenly 50% of the external plugins are not working that will be another thing users will notice.

At any rate, don’t get overly excited about gtk3, it’s just gtk 2.26 with a huge api break :). Once we decided which version we use in 4.12, I’ll post it on the blog.

LXDE still consumes less memory

*sigh* I’m not going to rant on this because as a user you should choose the desktop that makes you happy, but anyway it annoys me a tiny bit. So just to throw some information:

LXDE and Xfce are both based on the same toolkit and provide roughly the same set of features. That as a start makes it technically almost impossible to be much better or worse regarding memory usage. I think this whole myth started by comparing two distributions (clue: strcmp (distro_a + 1, distro_b + 1) == 0).

I’m sure Xfce consumes a bit more memory, because more processes are started. Especially when external plugins are added to the panel: a design decision to make the panel more stable.

I don’t know or care where this comparison started, but if somebody does this again the the future, please compare the actual memory usage and don’t use free. Or even better: don’t compare memory usage at all because it is pretty useless.
That said: if I start a default LXDE and Xfce 4.10 desktop (default Arch Linux packages) and use ps_mem.py, Xfce consumes 2 MiB more memory (same or desktop-equal applications are started). Do whatever you want this is number, as long as you compare apples and apples.

Not much accomplished in over 1 year

Sorry, I also work the entire week. But I don’t blame myself, Xfce is a fun project for all of us and if people move to another country, have a day job, a life, school/exams or simply don’t feel like working on Xfce not much progress is made.

Personally I don’t have the feeling not much was done in 4.10, we didn’t break anything major and a lot of the todo’s for 4.10 were completed in the release cycle. The focus was polishing and that’s what we did!

Updates:

  • 01-05 13:34: Added “Not much accomplished in over 1 year”.

Xfce 4.10 released!

Today, after 1 year and 4 months of work, we are pleased to announce the release of the Xfce desktop 4.10, a new stable version that supersedes Xfce 4.8.

In the 4.10 cycle we mainly focused on polishing the desktop and improving the user experience in various ways. Highlights of this release are:

  • A new application finder that has been completely rewritten and combines the functionality of the old xfce4-appfinder and xfrun4.
  • The panel now has an alternative vertical display mode (a deskbar). What is more, panel plugins can be arranged in multiple rows, which is particularly useful in the deskbar mode.
  • A new MIME type editor that allows you to easily change applications used for opening different file types. The mouse and touchpad settings dialog and the settings editor were extended in terms of functionality. The former now supports tablets in a much better way.
  • It is now possible to launch applications and open files on the desktop with a single click of the mouse. In addition, the 4.10 desktop can display thumbnails and automatically advance through the wallpaper list.
  • The window manager can be configured to tile windows when dragging them to the screen edges. The tab window (Alt+Tab) supports more flexible theming and cursor key navigation.

Release notes for 4.10pre1

The Xfce development team is proud to announce the first preview release for Xfce 4.10. Together with this preview release, the Xfce project announces the feature freeze for the final 4.10 release which is set to be pushed out to the world on April 28th, 2012.

This release incorporates major changes to the core of the Xfce desktop environment and hopefully succeeds in fulfilling a number of long time requests. Among the most notable updates is the new application finder that merges the functionality of the old appfinder and xfrun4. The Panel also has a new vertical mode [aka Deskbar] for better space usage on wide-screen monitors and a new actions plugin. On the settings side the settings helper is integrated in xfsettingsd, saving 1 running process. There is also a reworked settings dialog with categories and pluggable dialogs enabled by default. Basic Synaptics and Wacom settings in the Mouse settings and a new MIME-Type editor. Thunar gained a more polished layout to reduce space usage and more responsive interaction with the thumbnail generator. Because we have not decided on how to merge the desktop functionality into Thunar yet, Xfdesktop has instead received various improvements, including single-click support, desktop icon thumbnails and better pasting of files. The Session Manager has improved power management code, tips have been removed and cleanup sessions from the interface. Last but not least, the Window Manager now has support for tiling windows and arrow key navigation in the task switcher.

Another big change for users is the removal of user documentation of the packages and introduction of http://docs.xfce.org. The reason for this change is the limited contribution of documentation since Xfce 4.8, so we hope the wiki will attract more contributors. The help buttons in the interface still work, but you’ll be asked to open the documentation website in your web browser.

Furthermore we dropped xfce-utils. Its content has either been removed or moved to other Xfce packages. All other dependency changes are listed in the 4.10pre1 ChangeLog. The Xfce core also gained a couple of new components because we think they are critical for a minimal desktop: xfce4-power-manager (power management), tumbler (thumbnail generation for Thunar and other components), garcon (menu library, was already a dependency in 4.8), thunar-volman (volume manager for Thunar).

Of course translations also improved a lot, thanks to the amazing work of our translation teams.

A list of all changes is available on:

http://xfce.org/download/changelogs/4.10pre1

We hope you will enjoy this release. Please give us feedback by sharing your thoughts, blogging, tweeting, denting or by filing bug reports. With your help, 4.10 will be the best release ever (at least until 4.12)!

Kind regards and thanks to everyone who has contributed to this release,
