Hi,
Recently I start to work with Lua (programming language) and fond out that it is not easy to find some testing environment. At the end I have finished running lua through script and here is button which can be used to run lua scripts:
cmd /k "C:\lua\lua52.exe" {filepath$}
just download binaries from lua web site (it is absolutely free) and save it to some location. Make sure to update location in above button script.
Regards,
Dragan
