# debug.getprotos

Returns a list of every inner function defined inside a Luau function.

```luau theme={null}
debug.getprotos(func: function | level: number): {function}
```

`debug.getprotos` hands back every proto a Luau function holds at once. [Learn more here.](/docs/notes#protos)

The argument is the parent function, or a number. A number is read as a stack level instead of a direct function, the same way `debug.getinfo` takes a level. Pair an index from this list with `debug.getproto` to pull a single nested function out.

Most commonly used to find an inner function the game never stores anywhere you can reference, so you can read it or hook it.

## Parameters

| Parameter | Type                                                               | Description                                                                                |
| --------- | ------------------------------------------------------------------ | ------------------------------------------------------------------------------------------ |
| `func`    | <span style={{ whiteSpace: "nowrap" }}>`function \| number`</span> | The parent function, or a stack level pointing at the running closure to read protos from. |

## Returns

A table that holds every proto function defined inside the target (or inside the closure at the given stack level).

## Example

<CodeGroup>
  ```luau Example 1 theme={null}
  local getprotos = debug.getprotos(function(...) end)
  ```

  ```luau Example 2 theme={null}
  local mainfn = getscriptclosure(targetScript)
  local protos = debug.getprotos(mainfn)
  for i = 1, #protos do
      local inner = debug.getproto(mainfn, i, true)[1]
      print(`proto {i}: {tostring(inner)}`)
  end
  ```

<Tip>
  This lists all nested child functions defined in the parent function body.
