Ok I've found a workaround. It's not very clean but it works...

I modified the AppObserver.rb located in my openstudio folder : in the function onOpenModel, I added a [load 'myScript.rb'] in order to inject my script in the sketchup scope.

@tig said:

Have you tried also requiring the langhandler file?
require 'C:\product\SketchUp\SketchUp 2016\Tools\langhandler.rb'

Sorry I forgot to mention that I tryed to add this line too but I've the same error. I removed it because it is already required in sketchup.rb but I got an error in both cases.

It looks like my script cannot access those ruby files if I run it from outside sketchup

I also tryed modifying the sketchup.rb file : I set the entire path in [require 'langhandler.rb'] and then I got this error :

I think there's like a snowball effect, I guess that modifying all the sketchup's files is not the good way to proceed.

Hi guys,

I'm new to ruby and I wrote a script which automatize import of an .idf file in sketchup and exports it as a .dae file. WhenI load my script from the ruby code editor, there's no problem, but when I try to launch it from java, it seems like it cannot load the sketchup's dependencies I need.

Here is my java code :

            ScriptEngine jruby = new ScriptEngineManager().getEngineByName("jruby");
            jruby.eval(new BufferedReader(new FileReader("C;\\product\\SketchUp\\SketchUp 2016\\Tools\\api_dev.rb")));

(I added my script in this folder, don't know if its a good way to do...)

Here is the content of api_dev.rb :

require 'C;\product\SketchUp\SketchUp 2016\Tools\sketchup.rb'

model = Sketchup.active_model
model.close_active;
show_summary = true
status = model.import "C;/path/myIdfFile.idf", show_summary

# Or for a COLLADA (.dae) file, using the default options

options_hash = { ;triangulated_faces => true,
				;doublesided_faces => false,
				;edges => true,
				;author_attribution => false,
				;texture_maps => false,
				;selectionset_only => false,
				;preserve_instancing => true}
model.export 'C;/path/exportedDaeFile.dae',  options_hash

And here is the stacktrace I get :

LoadError; no such file to load -- langhandler

I don't understand why it doesn't manage to find langhandler file because its located in the same folder than sketchup.rb ...
Am I missing something when I try to retrieve the sketchup's ruby files ?

Thanks for you attention,
