I am still confused as to why we need ruby extension. Can't we just get the ISkpApplication COM interface and access Sketchup directly?
-
Well.. you never said specifically what you wished to do... so we are trying to cover all the bases.
If you will not call any standard Ruby functions, nor call any Sketchup Ruby API functions, nor access any Ruby object(s), nor expose any of your C/C++ objects to Ruby.. then
don't have the #include ".../ruby.h" line in your code.You won't know what your limitations are until you start playing.
Obviously... you'll need to #include whatever header files you require from the SDK source dirs.
-
I'm even more mixed up now
OK, if you import the Skectup.exe Type Library, you get the following...

ISkpDocument = interface(IUnknown)
['{E6E72823-A815-4760-91A1-76CED4F4AA60}']
function Get_Application(out pVal: ISkpApplication): HResult; stdcall;
function Get_ModelExtents(out pVal: ISkpBoundingBox3d): HResult; stdcall;
function Get_Fonts(out pVal: ISkpFonts): HResult; stdcall;
function Get_Materials(out pVal: ISkpMaterials): HResult; stdcall;
function Get_Layers(out pLayers: ISkpLayers): HResult; stdcall;
function Get_OptionsManager(out pVal: ISkpOptionsManager): HResult; stdcall;
function Get_ComponentDefinitions(out pDefinitions: ISkpComponentDefinitions): HResult; stdcall;

function Get_HLRView(out pVal: ISkpHLRView): HResult; stdcall;
function Get_CurrentCameraM(out pVal: ISkpCameraM): HResult; stdcall;
end;You can access everything using this, so that's why I'm puzzled as to why we need ruby at all. As far as I can tell, all we have to find is the Sketchup interface, and from there, we just have to query the interface for the active model and on an on.
...am I missing something? Or perhaps I don't know what I'm talking about or how Sketchup works at all???

Is there a compiler switch in MSVC to compile as a .so rather than a DLL?
Is the rest of the logic the same - for example the call to void Init_XXX() where XXX.so is the name of the .so file?
Thanks,

I totally agree, and we should be able to write plugins entirely in a dll.
There is a future pitfall for DLL files. Their support has been removed for the Ruby 1.9.x branch (which we are hoping that Sketchup begins using soon. Unicode string support etc.)
Anyway... the require() method will not load files with a DLL extension in Ruby 1.9.xYou do not need a real DLL file (to write a Sketchup plugin,) unless you are exporting DLL functions for public use by other non-Sketchup / non-Ruby programs.
Compile as a .so (source object) file if a DLL is not necessary.
BTW... you can always use the WinAPI C call LoadLibrary() to load a DLL. You can make the call using the Ruby Win32API.so extension, or Daniel Berger's newer win32-api package.

YES, because this requirement is hardcoded into Ruby. The require() method eventually calls dln_load() and other C routines in dln.c, which must know what the lib's entry point is. I think it is a simple and elegant solution, to use the lib's filename as part of the entry point init function. (Much easier than specifying some memory offset into the lib's code in an additional argument to the require method.)
- So because Ruby uses the lib's filename as part of the init function name, the lib file cannot be renamed after the fact by end user's, and still work.

Not that I can see... Ruby's mkmf script (the makefile generator,) seems to set .so as the default shared library file type.
So you'd need to compile at the command line, see examples in the sticky post.
To me it does look easier to create DLL with MSVS (the .def files simple to understand.)
There's not much differnce between a so and a dll, and you really don't need to worry about it until Sketchup actually supports Ruby 1.9.x, which may be years.

Just wish to also stress this fact from my previous post, that even with the Ruby 1.9.x lack of require() support for DLL files, ...
@dan rathbun said:

... and also Ruby 1.9.x replaces the Win32API.so binary file with a script named Win32API.rb, that maps old Win32API calls into DL module calls.

New 'old' info.
I found the old thread where we discussed this over on the Ruby Installer forum. Luis says on Windows that .so files are just renamed .dll files.
See: ruby uses .so files?
