Plugin DLL

Thanks Dan

You need some sample code called Simple Extension.
SketchUp doesn't seem to make it available, but they will let me send you a copy. See this thread: http://forums.sketchucation.com/viewtopic.php?f=80&t=13548
Send an email to al.hart@renderplus.com and I will try to send you a copy (if I can find one)
The "secret" is that you create a dll called, for example, ABC.DLL, then do require('ABC.dll'), (with the proper path, etc.), SkethchUp will load it and make a call to Init_ABC() (the name of your DLL) and you take it from there.
The sample DLL is linked with Ruby DLLs and cann access and modify SketchUp classes and more.

That's exactly what I'm after Al. I sent you an email. I appreciate all your help.

I found my previous emails and found a link to it, and sent it off to you.
Good Luck! (There is nothing easy about figuring this out and getting it to work.)
If you have some questions, post them here.

Thanks Al, this will help me so much I appreciate your time and super fast reply.

I wonder if we ( the community ) can set up a wiki page for how to create C extensions for SketchUp? It'd really help people getting into it.
-
We could put documentation on how to use it in Google Docs - either starting a new one - on on the SuWiki now located in the SketchUp Sage Site
What SketchUp told me was:

I believe Sang has (or will have) simple extensions in our SDK soon, but in the meantime it's perfectly okay to distribute this. The more people who know the techniques, the better.
Here is what I have been sending people:

You can download a copy from:
This is basically a Ruby Extension - and SketchUp has created a sample.
This lets you can C-code functions directly from SketchUp ruby, call SketchUp ruby functions directly from C-code, and also access SketchUp classes directly from C-code.
What would be good would be a case study where a new user tries to use it, and points out what it is difficult, gets help, etc.

I totally agree, and we should be able to write plugins entirely in a dll. First, I'm sure it's faster to execute since it's compiled, rather than interpreted by Ruby.
But I think the Sample Extension is incomplete. It will not compile as-is. All the rb_ functions are undefined, unless I'm missing something?
I can now see the concept, but it seems that every calls are passed as text, again slowing down the dll. Might as well write it all in ruby!
What about the Type Library 2.0? This gives us complete access to the Sketchup API, without having ruby as the middle man. If we can get the ISkpApplication interface when the dll loads, we are in business, every API calls are visible, and easy to use, ISkpOptionsManager, ISkpOptionsProvider, ISkpEntities, ISkpCurve, ISkpFileWriter to name a few.

You are..
You will need to download the Ruby source (Ruby is written in C,) and include ruby.h (and perhaps tchar.h)
See the ol' Pick-Axe Ruby book chapter: Extending RubyLink to SU 8.x Ruby source (v1.8.6-p287) zip

After you get the DLL working, you can access and modify SketchUp classes directly from the C-code. However, it turns out that it is somewhat slower to do things in C-code.
So we left most routines which access SketchUp classes in RUBY. We use the DLL to let us access Windows features, use Windows dialogs, etc. Also, things which do not directly access SketchUp classes are much faster in C++.

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.

Thanks to both of you, Al and Dan.
But I'm not sure which way to go anymore! I was under the impression that compiled code would run faster than ruby interpreter!!! As of ruby 1.8, the code is interpreted, not compiled into pcode or anything. So that confuses me even more.
So if 1.9 will not load a dll with require(), then there is no more point on writing a dll is there? The reason I wanted to do this in the first place is for speed, and the fact that I can created windows which you can't do in ruby unless you use html, but again, html is limited, and need extra files, javascript etc.
So what do you guys suggest? Which way is best for now and the future? I mean, they way to go about writing plugins? Simply using ruby and that's it? No more COM or anything?

Item (1): coders need to download Ruby source (links here)
Item (2): in the package, file stdafx.h, line 54:
#include "C:/ruby/source/ruby-1.8.2/ruby.h"
needs to be changed to the correct Ruby version source dir, for the plugin's targeted Sketchup version (ruby-1.8.0 for SU < 8, ruby-1.8.6-p287 for SU 8+)Item (3): WIN Sketchup is a MFC application. The package assumes the user will have a full edition of MS Visual Studio, which comes with the MFC source files.
Visual Studio Express editions do not come with these files.Express users can manually add the MFC header files, by installing the Windows Driver Kit Version 7.1.0 The download is an ISO DVD image, but some archive apps can open this type of file, such as 7zip, so you need not waste a blank DVD.
If you manually copy the header files from the ISO arhive, it looks as though the header files may need to be copied & renamed, ie: "_afxwin.h_00593" to "afxwin.h"
Then these files either:- moved to the Windows SDK/includedir, or the appropriate Visual Studio include dir, or 1. set VS-Express to use your WDK/include dir, via the Tools (menu) > Options (dialog)
If you install the WDK then you will not need to rename files, and the Installer may ask if you wish to integrate with Visual Studio, so the include paths may be added for you.

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.

ISkpDocument = interface(IUnknown)

function Get_Application(out pVal: ISkpApplication): 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.
