Is there a functionality similar to Python's 'if name ==
"main"' which will run only if you're in the actual file, and will
be ignored if the file is include'd from another?

I have this sort of file layout:

config.scad

// variables here

part1.scad

include <config.scad>
module part1() {
// part based on config variables
}

part2.scad

include <config.scad>
module part2() {
// another part based on config variables
}

render.scad

include <part1.scad>
include <part2.scad>
// the final "good" assembled view of the parts
transform([x,y,z]) rotate([a,b,c]) color("blue") part1();
transform([x,y,z]) color("red") part2();

I would like to see part1() rendered in the default position only when
I'm actually in part1.scad.

Once I am in render.scad, I don't want to see part1() rendered like
that, I only want to see the final "good" transformed/rotated/colored
instance of the part.

I tried a few methods like a "rendering = true/false" variable and
"use" instead of "include" but I couldn't find an automated method. I
suspect there is some solution using correct syntax which is not
immediately obvious to me.

Can this be done in some way?

To clarify, you want to have a part1() and part2() call in each file
respectively, but don't want to have those calls made when render
include()'s them?

The use<> should have worked to do that.

Alternatively you could put this in render.scad ($variables are dynamic
scope)
$main=1;

Then in the part file
if ($main!=1) part1();

If you don't like the warning add $main=0; to the part file.
