Easily Distracted

Curiosity gets the best of me sometimes. Okay, most of the time. Did you know GNOME’s text editor, gedit, has a plethora of extensions which can basically transform it into an IDE? Something I’ve always wanted is intellisense-style autocompletion. The closest thing I’ve found for gedit is GDP Completions Plugin in the gedit-developer-plugins package in Ubuntu.

sudo aptitude install gedit-developer-plugins

However, there’s a bug in that package and the popup menu doesn’t actually work. Ctrl + Space is supposed to bring it up. So you want to add the Gedit Developer Plugins PPA and upgrade to the more recent version.

sudo add-apt-repository ppa:user/ppa-name
sudo apt-get update
sudo apt-get upgrade gedit-developer-plugins

If you try to run gedit now, you’ll notice it won’t… run, that is. Great. I know, right? The problem is that the bzr plugin (also included in the gedit-developer-plugins package) is trying to use the gtk2 version of bzr-gtk, but that doesn’t work in the gtk3 gedit. Anyway, you can pull a copy of the gtk3 bazaar plugin into your local bzr plugins directory. (I found this info here). Create ~/.bazaar/plugins/ if it doesn’t exist.

mkdir ~/.bazaar/plugins
cd ~/.bazaar/plugins
bzr branch lp:bzr-gtk/gtk3 gtk

The gedit-developer-plugins package and gedit should work after that! An alternative to the above would be to add a PPA that includes bzr-gtk 3. Not sure if one exists at the moment, but that would be a cleaner solution. And you thought it would be simple. I know I did.

It’s not as polished or featured as other implementations, but it’s a good start. Here’s a screenshot after I type os. then hit Ctrl + Space:

GNOME 3.0 is due for release April 16 and I’m pretty excited by it. So I finally decided to check out first-hand how it’s progressing. My perspective is that of a GNOME 2.X user, but like many people, I was a little skeptical of the changes in 3.0. I tried the 0.0.6 image from the GNOME3 website and ran it off the USB key.

The Good

• It’s pretty. And minimal. Love the new font.
• High quality and scalable graphics and interface – tried it on both a 10″ netbook and a 23″ monitor with success. Large title bars and close buttons – easy to hit.
• All the updated core GNOME programs! I especially like the progress with Nautilus, the file manager. Instead of using a status bar, it uses a floating alt-type yellow info box to display info. Plus it seems much faster.
• Single stroke exposé-like effect that reveals all windows, scaled and tiled. This is bound to the Windows (Super) key, which actually makes it more appropriately named for GNOME3 than any version of Windows. Note: It can also be reached by clicking Activities in the top-left corner. From here, you can use your mouse to switch to a window or quickly close windows, launch/switch-to a program from the left sidebar, or you can start typing a substring of a program to run, or a string to search using wikipedia or google (these options appear after you type something… OR you can browse applications by clicking Applications. Additionally, on the right, you can manage workspaces. With the smart launcher and window manager functionality tied to a single key, I found myself actually starting to heart the windows key and its prime keyboard real estate.

  

• Don’t worry, you can still alt-tab! And it’s improved, with mouse input, and grouping instances of the same program.

  

• Integrated chat with notifications is great.
• Modal windows are now attached to their parent window (by default, this can be changed).
• Slick animations with meaning. Like the modal windows that slide out of the parent window’s title bar. I think OSX does something like this….
• Yelp, the Help browser is about a billion times faster. Seriously. This is largely due to the shift from gecko to webkit, I believe.
• No more minimize/maximize buttons. At first, I wasn’t sure about this and thought I wouldn’t like it, but the way the new desktop is designed, I don’t miss them. You can add them back, if it’s a concern. And all the old window shortcuts still work: [Alt+F9] = Minimize; both [Alt+F10] and [double-click title bar] = Toggle Maximize; [Alt+right-mouse-button] = window menu.

  

• GNOME is just much leaner than it has ever been before. Instead of starting 3 different programs at login (nautilus, gnome-panel, metacity), it simply starts gnome-shell.

The Bad

• Requires 3D support. Unfortunately, this is not always a simple request for us Linux users. Tried it on my netbook and failed. Couldn’t run it and probably never will thanks to the terribly supported poulsbo integrated graphics.
• And not just any 3D support… Tried it on my desktop, also with integrated graphics, but a better supported ATI x1250 – performance wasn’t stellar, but it was usable.
• Not very mature and not very customizable (yet). Panel Applets in prior versions of GNOME are extremely popular. Now we have this huge piece of space we can’t do anything with. But I’m sure something like panel applets will come eventually.
• It’s really hard to train myself to look to the middle of the top panel for the time/date… I keep looking at the top-right.
• Some of the changes had me fishing for functionality. Like, where is the control-center? It’s not in the Applications list under the Activities window. It’s under the user menu, under System Settings.

  

  And once you’re in the System Settings, you often want to change many things. At first, I was opening System Settings, selecting a component (they’re called Panels) to adjust (Background, for example), making changes, closing, repeat. When you open a panel from the System Settings window, that panel replaces the contents of the System Settings window. I didn’t notice the All Settings button that replaced the search entry in the dark grey area! After realizing that, it wasn’t so bad. And to be honest, I think the theme or something is not quite finished. Looking at other screenshots on the web, the button is much more noticable.

The Ugly

• BIG change in the way it expects people to use it. This will likely cause lots of frustration.
• Doesn’t quite seem ready for prime time. I guess that makes sense, it’s still beta.
• Some odd input lag every now and then. Visual artifacts. For both of these, I point my finger at my integrated graphics. Just a general lack of polish. But that’s to be expected with alpha/beta software.
• Bold, black window titles with same-colour shadow. Ugh… I expect that will change soon.

After trying Shell, I’m actually more excited for it. It still lacks polish in areas, which is expected at this point, but I love the direction GNOME3 is taking GNOME. I’m hoping I can get by on my integrated graphics, but I’m probably willing to purchase a low-end video card to get better performance. Anyway, I’m really interested to see how Canonical’s Unity and GNOME Shell will evolve side by side. Now I have to try Unity, I guess….

I decided that before I did any more work on the applet, I would improve its installation process to make it easier for people to try it out. So, the process to get and build the source now looks like this:

Download

• Browse source here.
• Download the source: bzr branch http://stevenbrown.ca/src/FileListApplet

Install

1. Install dependencies (Ubuntu package names given): sudo apt-get install python-xdg python-gnome2-desktop python-gtk2 python-pyinotify
2. Branch the source using the bzr command, above.
3. cd into the directory.
4. ./configure --prefix=/usr (the prefix is important!)
5. make
6. sudo make install
7. If the applet does not show up in your Add to Panel menu, try restarting the bonobo-activation-server: killall bonobo-activation-server.

Autotools

Autotools is pretty much the standard in source package management on linux. Except for the name, there is nothing automatic about autotools. Every encounter I’ve had with autotools has usually defeated me and left me frustrated and leaving whatever I was working on to do something else. For me, because I had labeled it the next step, it basically stalled the entire project for a while. Most people tend to copy and paste other projects’ autotools setup, but I figured that was overkill for my purposes and I didn’t find anything that quite suited me. I looked at gnome-blog, but it seemed like some stuff wasn’t quite working properly and some was completely unnecessary… in fact, this seemed to be a trend when looking at the autotools stuff in projects. Why is this? Autotools is not simple and due to this simple fact, I think it fails completely on many levels. Developers massage it enough to get it working, but few actually understand it all – I know I sure don’t! So please forgive the sloppiness and feel free to send patches. I gave up doing a couple things, like getting the revision number (bzr revno) and including it in the version string (see configure.ac). I know it’s probably something super simple, but I couldn’t seem to pass a variable containing a string as the version….

I feel that GNOME, as a platform for development, could seriously benefit from some kind of frontend to autotools that handled GNOME development nicely and hid as much as possible from the developer (including all those nasty config files that pollute the package tree). Anyway, I did not have an enjoyable time grappling with autotools, but I’ll end this mini-rant here.

Lots of people customize their desktops. Many don’t, but I do.. a little. Here’s mine:

I actually had to remove the Time Tracker (Hamster) applet to scale my 1280×1024 desktop down to 1024, but I think that was all. And I only just decided to try moving the Tomboy and Deskbar applets over to the top-left corner… looks a little odd, but it’s much more accessible. It’s good to try out new things, right? (When the keyboard will do, Alt+F12 and Alt+F3 for Tomboy and Deskbar, and Super(windows-key)+Space for Gnome-Do are good shortcuts to keep in mind.)

How about you? (If you run Ubuntu, read this – which is why I tried scaling my 1280 desktop to a 1024, in the first place).

This is kind of a proof of concept I’ve been playing with. The idea is that finding a file within a folder is often easier by type, and you are often only interested in the most recently modified file. The problem with a file manager is that although you can easily sort by either type or modification time, you cannot filter your view of all the other files you’re not interested in. I previously wanted to address this issue within Nautilus, (and I still believe this functionality would be wonderful in Nautilus), but I ended up doing this much less ambitious applet as a proof of concept.

This applet will let you add any number of folders to it, and will try to categorize the files automatically and intelligently. Currently, it’s more automatic than intelligent as it just looks at the mime-type. Even so, I’ve found it especially useful for keeping track of all my downloads:

Steven is catching up on the latest on planet.gnome.org and has downloaded a couple screencasts demoing the latest and greatest. These files are typically 2-10 megabytes, so they didn’t download instantly. Steven continues reading and forgot about the screencasts until a couple hours later. At that time, he can simply click on the File List Applet, select Downloads, select Video, and look at the top of the list for the newest files. Steven is happy. When finished, he can follow the same process to delete them – without once opening his file manager and being assaulted with ALL the files in his Downloads folder.

Ultimately, I would like to extend the idea to provide the same type/subtype menu system for all files under all folders – a type of summary – but I have not implemented that yet. There are other features in the cooking pot, as well, but I have to get started on some “RL” tasks… like my resume.

Screencast

I had a problem recording audio, so I ended up typing as narration. Unfortunately, this makes the YouTube one pretty unwatchable, but you can give the “HQ” version a try.

Download

No tarball yet as it’s still extremely rough.
Browse the source here.
Branch the source: bzr branch http://stevenbrown.ca/src/FileListApplet

Install

Update 2009/04/05: Updated install instructions here. (Some people don’t look at the comments….)

Installing will require some manual modifications.

1. First, make sure you have the following packages (Ubuntu): python-xdg, python-gnome2-desktop, python-gtk2, python-pyinotify
2. Then branch the source.
3. Adjust the FileListApplet.server file’s location to wherever you keep it.
4. Then copy FileListApplet.server to /usr/lib/bonobo/servers/.
5. Restart the bonobo-activation-server. killall bonobo-activation-server
6. Add it to the panel like other applets.

Update 2008/12/05: Added a couple screenshots.

In GNOMEe 2.24, hamster-applet will be included by default. When I use it, I love it. I should use it more often.

I should note that “laundry” is actually inclusive to other room-cleaning activities.
