gethook

Returns the replacement function installed on a hooked function.

Syntax

gethook(target: any) -> function

Parameters

Returns

Description

gethook looks up the live hook record for a function and returns the replacement closure that receives matching calls.

If the function is not hooked, the result is nil. The original behavior can still be obtained through the value returned by hookfunction.

Example

local original = hookfunction(print, function(...) end)
print(gethook(print) ~= nil) -- true
restorefunction(print)

Notes

• Closure operations act on live Luau function objects; installed hooks remain active until restored.
• Returns the hook, not the original function.
