Do you have a Selection made before this Tool is launched ?
It's not obvious from your screenshot.
You have its 'Materials' option set to 'Select from List' and its 'Scope' option set to list for 'Selection Only'...
This might then invoke an untrapped error ?
This obviously shouldn't happen... BUT it might explain things...
Try using it with a selection and/or some different option settings...

Good thought TIG, but from what I can see this should not cause the problem. I have specifically tested for no selection, and the error is also not a null pointer error. I think it has to do with it running on a MAC...

hm... the error is a missing refreshMaterial method - how can that be OSX specific?

I pass the method name in from javascript... the method certainly is there, and this code works on Windows... So somehow it does not resolve in this case.

So as far as I can see: either the method name coming in from JS (I assume the webdialog run in Safari on OSX) is somehow corrupted - how I do not know or I am not using the robust RUBY syntax in defining the method, and Ruby on OSX cannot find it.

For instance should I pre-pend it with "self". I do not know and cannot debug as I do not have OSX.

Has anyone else had this problem in windows, or got it working in OSX?

Myhand

cmd, I have done some experiments and suspect you may have a corrupt installation.

You can either:

fully delete the plugin. The whole ..\Plugins\Material_Maintenance folder. And the reinstall and see if you still get the problem
open your ..\Plugins\Material_Maintenance\Material_Maintenance.rb file in a text editor and see if on line 150 you have the following method definition:

def refreshMaterials(selectionOnly, wholeModel, components)
send me the ..\Plugins\Material_Maintenance\Material_Maintenance.rb file

I have looked into the file and I have found the required "refreshMaterials" definition.

Regardless, I will test it out on my windows system through parallels and let you know what I find.

Thanks CMD, that will be very useful. I hate not being able to debug it myself!

I've got a bridge in development in my TT_Lib2 library: http://www.thomthom.net/software/sketchup/tt_lib2/doc/
A JSON sub-class of a Hash and a bridge where I can call JS functions just with their name from Ruby and it will convert many types of objects to JS object and the return value of the JS function will be converted back into Ruby objects. Got most of the basic data types working and some of SU's custom classes, such as Vector3d and Point3d.
https://bitbucket.org/thomthom/tt-library-2/

Parallel to that there's a WebDialog bridge developed in SketchUp's Developer Tools they released as Open Source at last Basecamp: https://github.com/SketchUp/sketchup-developer-tools

You could have a look at either repos if it could help you.

It would have been interesting to create a standalone bridge as an open source project, avoiding each developer to create their own version.

Thank you thomthom, very impressive library! A shame I did not know about it before I started.

Unfortunately I already developed a basic bridge so changing it now would be more work than just adding a JSON marshal class. I wrote a basic one in ruby (so probably not the most efficient but works fine for the size of objects I want to pass). Does all objects, and escapes special characters etc. and does the trick for now. I will publish the code a bit later if anyone is interested. As all of my complex objects go from ruby to JS I have not written a parser (yet).

You have some experience with the C++ API. Does that give access to more attributes than the Ruby API. Specifically I want to change the material assigned to layers.

The C++ SDK for for reading and writing files. It's not something you can use from within SketchUp - manipulate the active model.
But if your goal it to generate a SKP file, then it might be the thing for you. However, I've not used it.

Regarding the Bridge - we talked about this at Basecamp (2012). I think the topic has potential for an Open Source project. We're currently testing out the experience of open source group projects with the STL Importer/Exporter and the Development Tools that SketchUp released. I'd like to see a bridge project established - and even more projects - so we can avoid redoing the work which the next man already have done.

Myhand

For anyone interested here is a link to the JSON formatter class I created. I am now using this for the next version of this plugin, which will allow you to pick a component and find its parent hierarchy. i.e. components containing nested instances of the specified component.

Myhand,

I installed the script on my windows version and all worked fine.

I also removed and reinstalled it on my Mac but I am getting the same error on launch of the script

Thanks CMD, sounds like my hunch might have been right and that it is something to do with the MAC.

Can anyone that has used the script on a MAC (successfully or otherwise) please let me know?

Else we might have to do this the hard way... CMD, if I add some debug code to the script would you mind running it and sending me the output?

Cheers,

Myhand, let me shake your hand!
this is a real helper (especially for those who render outside SU and care about mats order).
Thank you!

Hi CMD,

here is the file

Debug version

You can replace the Material_Maintenance.rb file in your ../Plugins/Material_Maintenance folder, restart sketchup, open the console window and launch the plugin. The script will output some debug to the console. Can you send me the whole console output please.

Cheers,

Here is the output from the ruby console after replacing with your posted Material_Maintenance.rb and launching the tool.

You may need to move the method definition of fromUIHandler to after the definition of refreshMaterials. Ruby might be trying to call refreshMaterials

  ` results = self.send(targetFunction.to_sym, *params)`

before it is defined.

I sent a PM.

Thanks CMD.

Unfortunately the attached output implies that the debug version of the Material_Maintenance.rb script did not run but rather the old version.

the error says:


Error; #<NoMethodError; undefined method `refreshMaterials' for #<MH_KeepingMyHandIn;;MaterialMaintenance;0x1383e920>>
/Library/Application Support/Google SketchUp 8/SketchUp/Plugins/Material_Maintenance/Material_Maintenance.rb;106;in `send'

and indicates the send method call is on line 106, while it is actually on line 122 in the debug version.

Have you restarted Sketchup after copying the new file in?

A few ways to check that the debug script is running are:

You should see this message in the console: "calling function >>refreshMaterials<<"; There might also be the same message but with other function names
The the above error appears again, it should be on line 122 not line 106.

Cheers,

myhand

cmd

sorry about that.

Unfortunately, here is what I get with your debug .rb
