filesystems - Get containing path of lua file

Question

I am wondering if there is a way of getting the path to the currently executing lua script file?

This is specifically not the current working directory, which could be entirely different. I know luafilesystem will let me get the current working directory, but it doesn't seem to be able to tell the current executing script file.

Thanks

EDIT: I'm not running from the standard command line interpreter, I am executing the scripts from a C++ binary via luabind.

This is a more elegant way:

function script_path()
   local str = debug.getinfo(2, "S").source:sub(2)
   return str:match("(.*/)")
end

print(script_path())
