I replaced my copy of NppScripting with jN today and noticed that the Zen Coding sample script was out of date—version 0.7 was released in March 2011 with plenty of new features, but it's only available for the old NppScripting API, bugs and all.
So I went ahead and modified the Zen Coding script to make it compatible with jN. Hope you'll find this useful. I'm not affiliated with the Zen Coding group, so I'll be sure to notify them as well.
I forgot to post a download link, sorry. Here it is.
How did jN get its name? ava (for) otepad++?
I called it NppScripting, but at next time I found another plugin called NppScripting based on Lua. I have decided to rename it.
avaScript for otepad++
