Redis geo.lua example using Go

I stumbled upon geo.lua which seemed to be an interesting library. It’s described as

“… a Lua library containing miscellaneous geospatial helper routines for use with Redis“

Here is an example of using it with the Go Redis client (go-redis). This is what it does in a nutshell

• adds (GEOADD) co-ordinates to a Redis Geo set
• geo.lua is invoked using EVAL
• executes GEOPATHLEN (a variadic form of GEODIST)

To run, refer README — its super simple

Cheers!
