Sardana editor is no more maintained and was removed from the code base in !1716. This decission was motivated by its low popularity (see Sardana Users Questionnaire 2020) and lack of resources to maintain it. If you are interested in this widget please contact us via the project issue tracker.
Some features of the sardana editor are:
plugins modules navigation
reload of the plugin code on the server
At the time of writing this document there is no script to directly start the editor but you can launch it with the following command specifying the door to which you want to connect:
python -m sardana.taurus.qt.qtgui.extra_sardana.sardanaeditor <door_name>
Sardana editor is still under development. If you find a bug please check the project issues if it was already reported and if not report it or directly propose a fix.
