Window 10 and Processing 4.4.4 here.
I can’t find a wiki here:
Home · processing/processing4 Wiki · GitHub
Just this for the processing-java in older versions:
Command Line · processing/processing Wiki · GitHub
I was able to launch a sketch:
D:\Program_Portable\Processing-4.4.4>Processing.exe cli --sketch="D:\Users\GLV\Documents\P4\Game_1_0_0" --run
This did not return anything:
D:\Program_Portable\Processing-4.4.4>Processing.exe cli --help
I can’t comment any further on this.
:)
