  • shortDesc: Kotlin Binding, Remove Internal Iterators

We are proud to release Elektra 0.9.10.

What is Elektra?

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

You can also read the news on our website.

You can try out the latest Elektra release using our docker image elektra/elektra.
This is the quickest way to get started with Elektra without compiling and other obstacles, simply run:

docker pull elektra/elektra
docker run -it elektra/elektra

Highlights

  • Kotlin Binding
  • Remove internal iterators

Kotline Binding

We created a new Binding for Kotlin with convenience functions and various utilities.
There is also the possibility to convert KeySets to Kotlin data classes or collections and back.
Read the Kotlin Readme for more information.

A big thanks to (@Gratla and @mandoway) for this beautiful work.

Remove Internal Iterators

In Elektra there are currently two different ways to iterate over KeySets.
The so-called "internal" iterator is, however, inferior and creates several problems, e.g. it was a side effect to be considered for every function call that involved a KeySet.

With this release, we started removing the internal iterators by removing keyRewindMeta, keyCurrentMeta, ksHead, and ksTail functions.
The external iterators are now the way to go, see Iterators.

A huge thanks to (Florian Lindner @flo91) for doing this thankless cleanup task.

Plugins

The following section lists news about the plugins we updated in this release.
Overall changes:

  • We changed all plugins, except directoryvalue to use external iteration of KeySets (Florian Lindner @flo91)

Python
