change geometric optimization type from command line ?

[ChameleonScales]

When you change the type of geometric optimisation from the GUI's dropdown (Position, View, etc...), it not only changes the value of optimizerMasterSwitch in the pto but also adds or removes lines under this line:

# specify variables that should be optimized

I tried running the same autooptimiser command on 2 pto files, one where only the value of masterswitch is changed and the other where also the other lines were added by saving from the GUI. The results came entirely different.

So here's my question : is there a command to properly change the type of geometric optimization in a pto ? That is, add or remove the necessary lines without using the GUI dropdown ?

optimize optimise optimizer optimiser

(I'm optimizing the searchability lol)

As usual I find my answer minutes after posting a question. It's as if formulating your question correctly makes you smarter!

The command line tool to use is pto_var with either --modify-opt --opt=something-something or just opt=something-something (and then -o output.pto input.pto)

To know how to get the exact same result as any selected item in the GUI dropdown I used a text diff tool (Meld).
