“main” function in Lua?

Question

In python, one would usually define a main function, in order to allow the script to be used as module (if needed):

def main():
    print(\"Hello world\")
           


        

Answer 1

Maybe you can just deal with the debug library, with the debug.getinfo() function

if debug.getinfo(1).what == "main" then
    -- Main execution
end

See the reference manual for more information.
