Can this be used to do standalone interpretation of <lua> scriptlets? I'm wondering about the issue that we have with rpm-ostree, which only supports bash scriptlets, so we end up rewriting <lua> scriptlets and filetriggers to bash for the sake of rpm-ostree.Well, it's a Lua interpeter, and so you can use it to execute Lua scripts from a file using the rpm embedded Lua interpreter so you'll have the same extensions loaded. It's not the same as getting executed from inside rpm transaction though because all sorts of context is missing, and this is not the intended use-case of the thing. That said, assuming the caller sets up scriptlet arguments and other state as per expectations, I don't see why simple scriptlets would not work. File triggers will not.
I was just thinking about something similar yesterday in the context of rhbz#2073170. The issue is that there is redhat-rpm-config macro using Lua string patterns. So if there was a way to reuse the patterns also from e.g. the build section, that would be useful.
