I wanted to know how I could edit the Lua registry?



https://www.lua.org/pil/27.3.1.html
This registry, should include all of the functions, userdata, booleans, and tables.

    "I" being who in this case? If you're in a Lua script, you can't touch the registry, period. If you're in C code, then you have complete control over the registry and can do whatever you want with it. So it's not clear what you mean here.

  • The registry doesn't store everything, it is a hidden table useful for native code to store references to Lua objects. You don't need it in Lua.

Lua registry is just regular Lua table. There just no reference to it from global scope.
You can e.g. use debug.getregistry() function to get it.
But be sure you know what you are doing.
And of course not all libraries stores its data in registry. Some of them use e.g. upvalues or uservalues to store some internal structure. Also any library can change its internals in any time. And most of them I think didn't expect that their data will be changed outside.

A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy...
