Example of Compiled Extension with SWIG and CMake

This sounds interesting.

A great idea floated around at Basecamp was to wrap the C++ SDK for file access with Ruby, that way developers could write Ruby scripts to access skp files from within SketchUp or at the command line.

That is very interesting!

I started a project to wrap the SDK for Ruby at:

Google Code Archive - Long-term storage for Google Code Project Hosting.

(code.google.com)

I am just getting started now and focusing only on Windows but hopefully this could be extended pretty quickly. Let me know if you are interested in helping/using.

Hey Dan, it was great to meet you at Basecamp. I do think this is an interesting project. I'm of no use in helping out with project, but I am interested in using it

I'm also interested in this project - though atm mostly of curiosity without any exact specific usage, yes.

I think you could, for example, write a .skp converter using ruby that worked on a .skp file instead of needing to run in SketchUp.

Batch conversions, thumbnail extraction, add/remove/modify geometry, explode, etc.

I imagine AdamB said at some point he'd managed to access setter methods for layers and materials via the SDK. Even get layer materials. Now that would be useful!

After working with the SDK for a little while I don't think it can be wrapped as quickly as I first thought. I have to get back to work on my real tasks so the SDK wrap project will have to wait for a while. But I did make another example using SWIG with directors to show how to pass Ruby objects into C++ code. We are looking into this to implement Ruby observers for events that happen in our own C++ code.

Hope this helps,

Hi, has anyone tried this on Mac OSX (10.6)?

For SWIG I did the standard: ./configure, make, make install.
but when i try to CMake your examples above i get this:

swig error : Unrecognized option -initname
swig error : Unrecognized option Example

for -initname "Example" in CMakeList.txt

also if i remove that it doesn't get better.

I tried SWIG versions 2.0.0 and 1.3.40 with no luck,
and I have ruby 1.8.7 (so should be no problems here...).

Please help,
Thank you.
