I added some more snippets :-)
This snippets will allow for easy code completion by offering itself when you type and press CTR+SPACEBAR in Kate.
Its an early version, there is more possible with scripts and stuff but I only use these functions for now.
There is also a icon file and Settings for Kate and a screenshot how to create a new filetype for .scad
If you want, improve it and write me a note. Then i will update this version with the better one :-)
Thanks and have fun creating stuff more easily :-)
Install the files in the directories written in the Readme files.
See the Settings Screenshots for the Kate settings.
You have to create a filetype for .scad files. This is easy!
Also maybe you need to enable the "Snippets tool view" pluigin in the settings of Kate.
Then click into the plugin-snippets-bar and click on "Add Repository" Then search for OpenSCAD.
These instructions work on KDE 5.
