Hi,
I'm trying to solve a problem with require (and the loaders it uses)
using the Thread's environment when I would rather it use the main
state's environment (the true global environment). Is there a cleaner
way to solve this than hooking the require function which temporarily
changes the thread environment to the main thread environment?
Something like (in Lua and untested):
do
local req = require;
local main_env = getfenv(0);
function require(...)
local env = getfenv(0);
setfenv(0, main_env);
local ret = req(...);
setfenv(0, env);
return ret;
end
end
Thanks for any help,
