- -- import
- -- the lua 5.0 loading mechanism is rather poor & relies upon the loadlib() fn
- -- the lua 5.1 loading mechanism is simplicity itself
- -- for now we need a bridge which will use the correct verion
- function import_5_0(name)
- -- imports the file into the program
- -- for a module 'example'
- -- this must load 'example.dll' or 'example.so'
- -- and look for the fn 'luaopen_example()'
- if rawget(_G,name)~=nil then return end -- module appears to be loaded
-
- local lib=loadlib(name..'.dll','luaopen_'..name) or loadlib(name..'.so','luaopen_'..name)
