sketchPath is different on OSX then Windows

Created by: clankill3r

Processing 4.3 (and prior)
Windows 10

When working outside the IDE it's common to put the libraries in a lib folder like: (even when not using processing this is common)

The above works fine on OSX, but on windows it does not work.
The reason it breaks on windows: https://github.com/benfry/processing4/blob/main/core/src/processing/core/PApplet.java#L7186

        if (jarPath.contains("/lib/")) {
          // Windows or Linux, back up a directory to get the executable
          folder = new File(jarPath, "../..").getCanonicalPath();
        }

It is assumed that core.jar is directly in the lib folder, in the above case sketchPath becomes rootOfProject/lib and dataPath becomes rootOfProject/lib/data.

For now I use this in my sketch:

    public void fixSketchPath() {
        try {
            Field sketchPathField = PApplet.class.getDeclaredField("sketchPath");
            sketchPathField.setAccessible(true);

            String sketchPath = (String) sketchPathField.get(this);

            if (sketchPath.contains("\\lib")) {
                int libIndex = sketchPath.indexOf("\\lib");
                sketchPath = sketchPath.substring(0, libIndex);
            }

            sketchPathField.set(this, sketchPath);

        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }

But this is of course more a work around then a fix.

Commencez dans core/src/processing/core/PApplet.java, au niveau de la logique de sketchPath autour de la ligne liée, et comparez la manière dont jarPath est géré sous Windows 10 par rapport à OSX. Reproduisez la configuration d’une bibliothèque dans un dossier lib et vérifiez que sketchPath pointe vers la racine du projet plutôt que vers le dossier lib, avec dataPath dérivé de cette racine.
