New notification work lands in Jaunty

Saturday, February 21st, 2009

Thanks to the concerted efforts of Martin Pitt, Sebastien Bacher and several others, notify-osd and several related components landed in Jaunty last week. Thanks very much to all involved! And thanks to David Barth, Mirco Muller and Ted Gould who lead the development of notify-osd and the related messaging indicator.

Notify-OSD handles both application notifications and keyboard special keys like brightness and volume

MPT has posted an overview of the conceptual framework for “attention management” at https://wiki.ubuntu.com/NotificationDesignGuidelines, which puts ephemeral notification into context as just one of several distinct tools that applications can use when they don’t have the focus but need to make users aware of something. That’s a draft, and when it’s at 1.0 we’ll move it to a new site which will host design patterns on Canonical.com.

There is also a detailed specification for our implementation of the notification display agent, notify-osd, which can be found at https://wiki.ubuntu.com/NotifyOSD and which defines not only the expected behaviour of notify-osd but also all of the consequential updates we need to make across the packages in main an universe to ensure that those applications use notification and other techniques consistently.

There are at least 35 apps that need tweaking, and there may well be others! If you find an app that isn’t using notifications elegantly, please add it to the notification design guidelines page, and if you file a bug on the package, please tag it “notifications” so we can track these issues in a single consistent way.

Together with notify-osd, we’ve uploaded a new panel indicator which is used to provide a way to respond to messaging events, such as email and IRC pings. If someone IM’s you, then you should see an ephemeral notification, and the messaging indicator will give you a way to respond immediately. Same for email. Pidgin and Evolution are the primary focuses of the work, over time we’ll broaden that to the full complement of IM and email apps in the archive – patches welcome :-)

There will be rough patches. Apps which don’t comply with the FreeDesktop.org spec and send actions on notifications even when the display agent says it does not support them, will have their notifications translated into alerts. That’s the primary focus of the effort now, the find and fix those apps. Also, we know there are several cases where a persistent response framework is required. The messaging indicator gets most of them, we will have additional persistent tools in place for Karmic in October.
