Event listener for loading progress of referenced blocks

Hi!

I have a large rhino file that contains many referenced blocks. I’d like to show feedback on the loading progress, using a script that I add to “File>Properties…>General>Run these commands when rhino starts”

For the script I’d need to know the total number of references in a model before rhino starts loading external references.

Is there a function that returns the count of referenced files to load? I have attached an example file and pseudo code below

Thanks,
Tim

import Rhino
import scriptcontext as sc

def OnBeginOpenDocument(sender, e):
    count = sc.sticky.get('count')
    total_count = sc.sticky.get('total_count')
    
    if e.Reference:
        print 'loading (%s/%s): %s' % (count, total_count, e.FileName)
        sc.sticky['count'] += 1
        
def main():
    
    # get total count of references to load, before loading starts
    # line below needs to be replaced with a function that returns the count of (block)references to load
    total_count = len(sc.doc.Objects)

    sc.sticky['total_count'] = total_count
    sc.sticky['count'] = 0
    
    Rhino.RhinoDoc.BeginOpenDocument += OnBeginOpenDocument
    
 if __name__ == '__main__':
     main()
