The new Diodon release 1.8.0 is out the door – a special release focusing on developers.
Due to removing Vala specific libgee (Thanks to RedHatter) it is now possible to more easily write plugins/services in gjs and python. Look for example at the work happing on the Gnome Diodon Indicator.
This release now also supports new Vala version 0.40 so it can be more easily packaged.
What might interest you most though is that we have moved our code base to GitHub. We hope this helps you to more easily contribute to Diodon by opening pull requests.
Issues are still on Launchpad where you may have a look where you could contribute to. Or if you wanna write a plugin there is a Blueprint with lots of ideas.
To get started beside installing newest version from git you can either download new release as tarball or install it through the ppa with the following commands:
sudo apt-add-repository ppa:diodon-team/stable sudo apt-get update sudo apt-get install diodon # and for all Unity users there is also a scope sudo apt-get install unity-scope-diodon
Looking forward to many more contributions to Diodon ;).
