Multiple installs of Processing

[mario60]

A very simple question:
If I install two or more versions of Processing (say 3.5.4 and 4.3), how do I get separate sketchbook folders? And how do I get different desktop shortcuts and menu items? As far I see, what I install later overwrites what is already there. I am on a Fedora 39 machine. Do I need to hack install.sh?
Thanks

EDIT. Within Processing 3.5.4 / install.sh, change a line as to have RESOURCE_NAME=processing-3-pde.
Similarly, rename as to have lib/processing-3-pde.xml, and sketchbook3.
Within home/../.processing , add

sketchbook.path.four=/home/.../sketchbook4  (for 4.3)
sketchbook.path.three=/home/.../sketchbook3

Run the modified Processing 3.5.4 / install.sh.
It should work.

(note to developers, different versions should be shipped with versioned install.sh files as to let install multiple versions without any overwriting)

I cannot change Sketchbook folder

File "%AppData%\Processing\preferences.txt" is where Processing looks up its configuration. Among them we have properties such as these 3: sketchbook.path= sketchbook.path.three= sketchbook.path.four= Which determines the each “Sketchbook” path for Processing versions 2, 3 & 4 respectively. Again, have utmost care when upgrading Processing to a major version, as not to mix those paths! Otherwise libraries, modes and tools will conflict w/ each other due to major version incompatibility!

Sample code to create SVG file, using Processing 4.1.1 with Python mode

Recently I’ve moved my “processing-3.5.4” app folder from a Win 8.1 laptop to another 1 w/ Win 10 and it works the same. However, b/c you also have Processing 4, you’re gonna need to have separate sketchbook folders for both P3 & P4. Here’s a way to do it on Windows: 1st, close all running Processing instances, so they won’t overwrite the “preferences.txt” file we’re gonna edit later. Go to folder %USERPROFILE%\Documents and create a subfolder named code or another name of your liking. …
