I'd like to input a vector of the type [[a,b],[c,d]] via the Customizer
pane.

I am able to input  a simple vector with a line that looks like this:

Variable = [];

Then I can paste the value [a,b,c,d,e] into the Customizer pane and process
that vector within the code.

For a vector of vectors, I've tried:

Variable = [[],[]];

But I can't change the displayed value by pasting [[a,b],[c,d]].

I'd be OK with using a string input variable and then using some conversion
function to take the string "[[a,b],[c,d]]" and turn it into a vector, but I
don't see that functionality in vanilla OpenSCAD.

Any ideas?

Thanks,

Ken

how about

Yes, though that creates two inputs in the customizer rather than one.

how about

ab=[5, 10];//[[-100:100], [-100:100]]
cd=[5, 10];//[[-100:100], [-100:100]]
abcd = [ab, cd];
echo(abcd);

To get a single input line, you obviously can write:

abcd=[5, 10, 5, 10];//[[-100:100], [-100:100], [-100:100], [-100:100]]
variable= [[abcd[0],abcd[1]], [abcd[2], abcd[3]]];

echo(variable);

However, you are right, this is just a work around, as the customizer isn't
as structure sensitive as it could/should be.
