What is Elektra?

Elektra serves as a universal and secure framework to access configuration settings in a specified, global, hierarchical key database. For more information, visit https://libelektra.org.

Notification: New transport plugin

To keep persistent configuration settings in sync with the configuration settings of applications, notifications are needed. For notifications it is important that they do not block the execution of the applications. In Elektra we achieve this using transport plugins.

Elektra's notification feature has received its first transport plugin pair: D-Bus. Transport plugins provide a link between applications using Elektra. These plugins send and receive notifications when a key is modified within the key database. The existing dbus plugin has been modified to use an asynchronous I/O binding for sending messages, if available. The new dbusrecv plugin is responsible for receiving messages sent from the dbus plugin and other sources with the same message format.

For more details see the notification tutorial or the example applications.

Thanks to Thomas Wahringer.

Web UI greatly improved

The goal of the Web UI is to provide safe and unified access to all configuration settings of a system. Different to other UIs, it generates its interface according specifications as found in Elektra.

For example, if a configuration setting only has a number of choices, you get exactly these choices within the user interface.

To get outstanding usability, Web UI now provides:

Note that new version of the Web UI requires Elektra 0.8.23 or later.

Thanks to Daniel Bugl.

Overhaul of Build System and Daily Stretch Repository

We started to overhaul our build system to improve build times and responsiveness. It focuses heavily on containerisation to improve hardware utilization.

If you are interested in #devops have a look at our Jenkinsfile.

Daily builds Debian packages for Stretch are available again in our stretch repository. Add it to your sources.list:

deb     [trusted=yes] https://debian-stretch-repo.libelektra.org/ stretch main
deb-src [trusted=yes] https://debian-stretch-repo.libelektra.org/ stretch main

Thanks to Lukas Winkler.

Elektra Initiative are the people behind Elektra. Our goal is to build up expertise with configuration settings and improve the situation in the FLOSS landscape. To learn more about the needs of configuration-wise non-trivial FLOSS applications, we have workshops. After a successful workshop with the LCDproc's maintainer, the next Workshop will be with people from KDE.

We will use the opportunity of Akademy being in Vienna. We already got positive feedback from kconfig maintainers (David Faure and Aleix Pol).

If you are interested, you can sign up. We are looking forward to an informative, interactive and interesting workshop!
