      And what about Classes defined by SketchUp? How does one handle them?

        you can use rb_funcallX (see Ruby Interpretor Interface) to call methods from the classes or you can use array/hashes to pass data

          Say I got a collection of Point3d, Vector3d. Would it be best to convert those to arrays of basic numbers in Ruby and passing onto C? Or would it really not matter?

          
          static VALUE test(VALUE vector)
          {
            VALUE arr;
            arr = rb_funcall(vector, rb_intern("to_a"), 0)
          }
          
          

          This would leave me with arr being an Ruby Array representing the vector, right?
          I see there are rb_each and rb_iterate - should one use ruby iterators to loop through Ruby Arrays in C? Or can one use regular C loops?

          Are there further reading than this page: http://www.ruby-doc.org/docs/ProgrammingRuby/html/ext_ruby.html

            right

            definitely rb_ functions as you are manipulating an array of pointers (VALUE objects)

              I am confused again now. I got Pellets. And I did what the article said about generating a makefile. But I'm confused to how I compile it.
              From what I understand, make is a UNIX command?

                Ok, getting close I think, - from the Pelles C Project options I added C:\Ruby\lib\ruby\1.8\i386-mswin32 to the includes path.

                But now I get:
                Building helloworld.obj. C:\Ruby\lib\ruby\1.8\i386-mswin32\config.h(2): fatal error #1014: #error: MSC version unmatch. *** Error code: 1 *** Done.

                ❓

                  Pelles crashed on me - and I swear I heard Homer Simpson's "doh!" as it crashed... 😲 😆

                    just double click on suext.ppj and it will open in PellesC IDE and then you can Project | Build and you will get a suext.so ready to use

                      Tried that - but it complained about the project being in the wrong location. Thereafter I got the error I posted in previous post.

                        When I google the error - all I find is people suggesting that one remove
                        #if _MSC_VER != 1200 #error MSC version unmatch #endif
                        from config.h.

                        I take it that you found a way around that?

                          When I open the .ppj files in a text editor I see some minor differences.
                          What kind of project template do you use?

                            added suext6.ppj in SUExt dir on github. it should work now. I use PellesC 5 and something was changed in 6 that made that error.

                                    Say that I have a module Foo defined in my ruby script containing a method bar.

                                    How can I reference Foo in C so I can for instance call bar?
                                    symbol = rb_intern("bar"); rb_funcall(??? , symbol, 0);

                                    Would I use VALUE rb_define_module(const char *name) ?

                                    module = rb_define_module("Foo"); symbol = rb_intern("bar"); rb_funcall(module , symbol, 0);
                                    ❓

                                        Just wanted to make sure - some times something appear to work - but later turns out to be very wrong.
