A much anticipated feature, namely Postfix code completion, is right underway, realized through Nicolaj Höss in his bachelor thesis coached by me. Check out the demo video
and install the current feature into your Eclipse Luna from https://github.com/trylimits/Eclipse-Postfix-Code-Completion.
Comments always very much welcome, please use the respective github issues page.
Congratulations to Nico Höss for passing his bachelor thesis at the University of Applied Sciences Vorarlberg on the topic, you did a great job! 🙂
