AutoIt /ɔːtoʊ ɪt/ is a freeware programming language for Microsoft Windows. In its earliest release, it was primarily intended to create automation scripts (sometimes called macros) for Microsoft Windows programs but has since grown to include enhancements in both programming language design and overall functionality.

The scripting language in AutoIt 1 and 2 was statement-driven and designed primarily for simulating user interaction. From version 3 onward, the AutoIt syntax is similar to that found in the BASIC family of languages. In this form, AutoIt is a general-purpose, third-generation programming language with a classical data model and a variant data type that can store several types of data, including arrays.

An AutoIt automation script can be converted into a compressed, stand-alone executable which can be run on computers even if they do not have the AutoIt interpreter installed. A wide range of function libraries (known as UDFs, or "User Defined Functions") are also included as standard or are available from the website to add specialized functionality. AutoIt is also distributed with an IDE based on the free SciTE editor. The compiler and help text are fully integrated and provide a de facto standard environment for developers using AutoIt.

AutoIt was originally a closed-source project and briefly became free and open-source, licensed under the terms of the GNU General Public License (GPL). The free and open-source AutoHotkey project derived 29 of its functions from the AutoIt 3.1 source code.

Beginning with version 3.2.0 in August 2006, the app switched to a closed-source model.

Features

AU3 File Format Icon

AutoIt is typically used to produce utility software for Microsoft Windows and to automate routine tasks, such as systems management, monitoring, maintenance, or software installation. It is also used to simulate user interaction, whereby an application is "driven" (via automated form entry, keypresses, mouse clicks, and so on) to do things by an AutoIt script.

AutoIt can also be used in low-cost laboratory automation. Applications include instrument synchronization, alarm monitoring and results gathering. Devices such as CNC routers and 3D-printers can also be controlled.

Examples

Hello world

; Make available a library of constant values.
#include <MsgBoxConstants.au3>

; Displays "Hello, world!" in a messagebox.
MsgBox($MB_SYSTEMMODAL, "Title", "Hello, world!")

Automating the Windows Calculator

; Make available a library of constant values.
#include <MsgBoxConstants.au3>

; Display a message box with a timeout of 6 seconds.
MsgBox($MB_OK, "Attention", "Avoid touching the keyboard or mouse during automation.", 6)

; Run the Windows Calculator.
Run("calc.exe")

; Wait for the calculator to become active with a timeout of 10 seconds.
WinWaitActive("[CLASS:CalcFrame]", "", 10)

; If the calculator did not appear after 10 seconds then exit the script.
If WinExists("[CLASS:CalcFrame]") = 0 Then Exit

; Automatically type the current year into the calculator.
Send(@YEAR)

; Let's slow the script down a bit so we can see what's going on.
Sleep(600)

; Automatically type in 'divide by 4', and then sleep 600 ms.
Send("/4")
Sleep(600)

; Hit the return key to display the result, and sleep 600 ms.
Send("{ENTER}")
Sleep(600)

; Copy the result to the clipboard using the Windows shortcut Ctrl+C.
Send("^c")

; Declare, and assign the contents of the clipboard to, a variable.
Local $fResult = ClipGet()

; Check to see if the variable contains a decimal point or not.
If StringInStr($fResult, ".") Then
    ; Display a message box with a timeout of 5 seconds.
    MsgBox($MB_OK, "Leap Year", @YEAR & " is not a leap year.", 5)
Else
    ; This message will only display if the current year is a leap year.
    MsgBox($MB_OK, "Leap Year", @YEAR & " is a leap year.", 5)
EndIf

; Close the Windows calculator - always tidy up afterwards.
WinClose("[CLASS:CalcFrame]")

Find average

; Find Average by JohnOne, modified by czardas
#include <MsgBoxConstants.au3>

_Example() ; Run the example.

Func _Example()
    ; Display an input box and ask the user to enter some numbers separated by commas.
    Local $sInput = InputBox("Find Average", "Enter some numbers separated by commas: 1,2,42,100,3")

	; If an error occurred then exit the script.
	If @error Then Exit

    ; Populate an array with the user's input.
    Local $aSplit = StringSplit($sInput, ",")

    ; Pass the array to the function _Find_Average() and then check for errors.
    Local $fAverage = _Find_Average($aSplit)
    If @error Then Exit

    ; Display the result in a message box.
    MsgBox($MB_OK, "Find Average", "Result: " & $fAverage)
EndFunc   ;==>_Example

Func _Find_Average($aArray)
    ; If the input is not of the correct type (an array), then return an error along with the details.
    If Not IsArray($aArray) Then Return SetError(1, 0, VarGetType($aArray))
	; More detailed checks are possible, but for brevity just one is performed here.

    ; Declare a variable to store the sum of the numbers.
    Local $iArraySum = 0

    ; Loop through the array.
    For $i = 1 To $aArray[0]
        ; Increment the sum by the number in each array element.
        $iArraySum += Number($aArray[$i])
    Next

    ; Return the average rounded to 2 decimal places.
    Return Round($iArraySum / $aArray[0], 2)
EndFunc   ;==>_Find_Average
