[Qgis-user] Python Scripts (Boolean) in QGIS 3

[Stefan Giese (WhereGroup)]

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
