As usual I do not fully get the question. Assuming the tutorial http://gimps.de/en/tutorials/gimp/pictur.../index.htm which references the Hue Saturation tool.
...must be from Gimp 2.8 era...then using Colors -> Hue Saturation I can see no difference, the only addition being the Gimp 2.10 blending option. Importing a Gimp 2.8 image will set the layer group mode to Legacy and you can change this to Default. Examples using the first setting given, H=0 L=60 S=-70 Inset is Gimp 2.8 No layer modes in there.
If not the issue, just for my peace of mind, can you post an example screenshot, or point to the part of the tutorial which uses layers.
or is it a scripting question.
