Drawbot question: where's CurrentFont()?

I was trying Georg’s Drawbot plugin. I thought I could just run any Drawbot scripts (including ones for RoboFont) but I couldn’t. The one I tried has a statement like f=CurrentFont() which should be kind of similar to Glyphs.font, but it’s not working. How compatible is the plugin supposed to be with the actual Drawbot? Is it easy to fix the code to make it run? Is there any documentation of the Glyphs version?

You need to import it yourself. I’ll need to fix that.
