Comment 1 Rigo Wenning 2020-04-06 11:56:12 UTC 
BTW, searching for the emmet script, I have NO script anywhere for kate, kwrite or ktexteditor. Where can I actually find the script?
Comment 2 Christoph Cullmann 2020-04-26 15:10:22 UTC 
The script is compiled as resource into the lib.
It is located in the ktexteditor.git repo

https://cgit.kde.org/ktexteditor.git/tree/src/script/data
