isfunctionhooked - Mintlify Starter Kit

Tells you whether a function is currently hooked.

isfunctionhooked(func: function): boolean

hookfunction hooks a function and restorefunction puts it back. isfunctionhooked only reports the current state - it never hooks or restores anything itself.

Parameters

Parameter	Type	Description
`func`	`function`	The function to check.

Returns

true if func is currently under a hookfunction hook, false if it never was or has since been restored with restorefunction.

Example

The common use is a guard: check isfunctionhooked before hookfunction so you never double-hook the same function. This run also shows the flag flipping back after restorefunction:

<<<<<<< HEAD
local hooked = isfunctionhooked(print)
=======
-- isfunctionhooked(func: function): boolean
>>>>>>> 50e30f53759b0538759af25c9b271514aa2c9290

local function greet()
    print("hello")
end

print(isfunctionhooked(greet)) -- false, nothing has hooked it yet

if not isfunctionhooked(greet) then
    local original = hookfunction(greet, function(...)
        print("hooked")
        return original(...)
    end)
end

print(isfunctionhooked(greet)) -- true

restorefunction(greet)
print(isfunctionhooked(greet)) -- false again, back to the original body

Checks internal executor state to see if a hook is active on the function.
