How to spread a variable in AutoHotkey?

Question

In JavaScript, we use the spread operator to spread an array of items, e.g.

const arr = [1, 2, 3]

console.log(...arr) // 1 2 3

And I want to achieve a similar effect in AHK:

Position := [A_ScreenWidth / 2, A_ScreenHeight]

MouseMove Position ; 👈 how to spread it?

Answer 1

AFAIK, there's no spread syntax in AHK, but there are some alternatives:

For big arrays you can use:

position := [A_ScreenWidth / 2, A_ScreenHeight]
Loop,% position.Count()
    MsgBox % position[A_Index] ; show a message box with the content of any value

or

position := [A_ScreenWidth / 2, A_ScreenHeight]
For index, value in position
    MsgBox % value ; show a message box with the content of any value

In your example, can be:

position := [A_ScreenWidth / 2, A_ScreenHeight]
MouseMove, position[1], position[2]

This will move your mouse to the bottom middle of your screen.

To avoid decimals, you may use Floor(), Round(), Ceil() functions for example, like:

position := [ Floor( A_ScreenWidth / 2 ), Round( A_ScreenHeight ) ]
Loop,% position.Count()
    MsgBox % position[A_Index] ; show a message box with the content of any value
