How about this:
$ mkdir -p com/example/
$ cat > com/example/graphics.lua
local M={}
function M:test()
return 'Tested'
end
return M
$ lua -e 'graphics=require "com.example.graphics"; print(graphics:test())'
So you make a local module and put it inside a namespace by installing
it in your subdirectory (com/example), and return just a table. Then the
caller decides where to assign the required module.
Calling graphics:test() is faster than calling com.example.graphics:test().
You can also move your module to another subdirectory, and would need to
change only 1 line of the caller code - no changes to the module itself.
This is lua 5.2 compatible. The above module is in plain lua, but you
could do the same for C bindings.
