I posted this before in a topic related to a question. The last two days I have spent some time cleaning up the project and getting rid of dependencies.
Anyway, what I made is a renderer that can be set using:
size(1120, 850, P5_Terminal_Graphics.TERMINAL);
And then when an external console is used, then that can be used as a display.
You need an external editor. VScode is now way easier to get working with processing then it was before. If you like to try it out and have problems setting it up then open an issue on the github page and I will help you.
Also on github is more information.
