Sorry for the huge delay. Enough pulls on my time and this god somewhat sidelined. I have done a large number of fixed and improved some of the warnings. However while I was making everything work on OpenSCAD 2019 the 2021 version has been released. SCA2D v0.0.7 now can handle multiple files, and no longer fails epically on list comprehensions. It also prints a nice little summary. Some lower level changes have allowed me to improve the unit testing. Of course there are tonnes more tests needed. It will be some time before I get to looking at 2021 syntax because my main project has not moved over to it yet. I also still need to implement OPENSCADPATH. -- Sent from: http://forum.openscad.org/
