Show HN: LadyLua, batteries-included static Lua 5.1 interpreter
6 projects | news.ycombinator.com | 8 Apr 2021
GopherLua  is a Lua implementation written in Go, not just a wrapper around the C implementation.
The main alternative seems to be Shopify’s go-lua , given that Microsoft’s golua  is no longer being developed. The main difference between these three implementations seems to be the supported Lua version - 5.1, 5.2 and 5.3 respectively.
We haven't tracked posts mentioning tengo yet.
Tracking mentions began in Dec 2020.
