I panicked. The Lua error was really scary, but it just involved making one of the files writable. And I missed out on a couple of modules.
It's working now-- I'm still amazed that it is-- I should be more trusting of the process.
For anyone else who wants to try it, it works! Below is a list of templates and modules you need:
Module:Check for unknown parameters Module:Arguments Template:Yesno-no Module:Tree chart/data Module:Tree chart Template:Tree chart Template:Tree chart/end Template:Tree chart/start Template:Related Template:Chart bottom Template:Chart top Template:Mbox Template:Ombox Template:Template link Template:Para

Has anyone had experience with Wikipedia's family tree feature? I've downloaded all the templates from Wikipedia but I'm getting Lua errors that are a bit outside my understanding. I'm wondering if it's worth my time.
Is there a trick to it? Are there tutorials?
Can you say more about how you downloaded them, and what errors you are getting?
I just tried exporting "Template:Tree chart" using https://en.wikipedia.org/wiki/Special:Export with the 'Include templates' option checked, then imported the XML file I got using Special:Import on my test wiki, and at a glance everything works perfectly, with no tricks needed.
