I got a reply from Calico Pie. They asked for a link to a version which works with lua 5.3, which I supplied. I replied with a link, they said thank you and closed the ticket. They said they would check it out, but obviously, didn't give a timeframe.
Meanwhile, I'm busy cleaning up place names in my husband's database. Among other things, he managed to create a bunch of duplicates, by adding a space to the end of places he was entering. He was using a phrase manager and didn't check the box to remove the terminating delimiter. Creative, no? He was so proud of himself for making his own phrase without my help. I guess I have to give him points for trying.
Lua Rocks is definitely on my list of things to do. I'm not going to wait for Calico Pie. But, as you say, it's not an easy tech to get into. I've been doing this since the late 70's and have learned a lot of new stuff, but this definitely ranks up there with some of the most incomprehensible stuff I've learned.
