Hi Herbert,
with processing scripts ist has defintitly changed a lot. The thing is,
that in QGIS 2.18 it was python but mixed with some none python, like
the parameter with the double pound sign...like ##my_parameter=boolean

so a good starting point is the blog from Anita Graser, since the
documetation on qgis.org isn't that actual at the moment:
https://anitagraser.com/2018/03/25/processing-script-template-for-qgis3/

you can also start with the template directly in QGIS selecting "New
script from template.." in the processing toolbox top, where the python
icon is...

Hope this helps a bit
Stefan
