getgenv

Returns the custom global environment of the executor.

function getgenv(): table

Synopsis

How it works

The executor maintains a separate Luau lua_State with its own global table (_G). getgenv() returns a reference to this table. All executor scripts share the same global environmentGlobal environment (genv)The executor's global environment table — the _G-equivalent for executor-loaded scripts. Functions set here (via getgenv()) are accessible from any executor script but invisible to game scripts., so writing getgenv().x = 1 in one script makes x available in any subsequent script execution.

Memory model

Internally, every Luau thread carries an env pointer (its global environmentGlobal environment (genv)The executor's global environment table — the _G-equivalent for executor-loaded scripts.

The executor creates a master environment table at injection time and points all executor threads to it. Game scripts point to a completely separate table — the Roblox global environment. This isolation prevents cross-contamination.

Relationship to getrenv

getgenv() → executor's global table (your scripts)
getrenv() → Roblox client's global table (game scripts)
Both are normal Luau tables, but they reference different lua_State environments

Usage

Shared variable

getgenv().MySharedLib = {
  greet = function(name)
    return "Hello, " .. name
  end
}

"cc">-- Accessible in any other script:
print(MySharedLib.greet("World")) "cc">-- "Hello, World"
