Is there a way to detect if an Extension is loaded or not?

thomthom · 9 Dec 2010, 21:39

Not exactly what I asked for, but I found this to be useful:
$LOADED_FEATURES.join("\n")

Lists all loaded files, even those loaded with Sketchup::require.

Could use defined?() to check for modules, variable, etc.

Though, doesn't list loaded .rbs files.

$" This pre-defined variable, an array contains the module names loaded by require.

That's the same as $LOADED_FEATURES isn't it?

in reality, I do not know
but
puts $LOADED_FEATURESreturn nil
puts $" return that

By cons no return for files rbs

YES.

Verify with .object_id

The problem with rbs loading is a bug. The rbs loader (Sketchup.require and/or Sketchup.load,) should upon sucessful load of an rbs file, push the path argument into the $" array, just as the Ruby native Kernel.require does.

I think the way they wrote it, you must not specify the file extension.
If you wish to require widget.rbs then you use:
Sketchup.require 'foldername/widget'
and then you might see 'foldername/widget' as one of the elements in the $" array.

Yes, but you need to modify the SketchupExtension class.
I did exactly that and a whole lot more (mods the class,) for my own personal use.

No point in me releasing it, as you guys generally don't like these sort of mods, and also Google will not use "unsolicited code contributions" (which is why I now understand why Jim gave up on the SKX project.)

That's what I do - no file extension for .rbs files, but I've not found them listed anywhere.

I avoid it in released code as it's the same as not wrapping the code in modules - too much chance for conflicts. That's my reason for skipping out of the SKX project.

Though for debugging and experimenting I occasionally do it. Recently extended the Menu, Toolbar and Command class to intercept the creation of the UI elements - might be a way to make an UI manager.

I probably shouldn't have - it can still be a valuable project. I think if I/we had pushed through, people would have started to use it and we might have a quality piece of work by now.
