[Bf-committers] blender exit code after exec python

[Diego Gangl]

Hi,

I don't know if this is by design, but it makes sense if it were. Scripts
are run inside Blender, but they are not blender and the interpreter isn't
the main function (even on background).

For a cleaner way to exit, you can use a SystemExit exception like this:

raise SystemExit("oops")

It will print "oops" and set the exit code to 1. You can pass an integer
instead of a string to set the exit code manually too.

Cheers,
