AutoIt (/ɔːtoʊ ɪt/ aw tow It) [2] is a freeware automation language for Microsoft Windows. In its earliest release, the software was primarily intended to create automation scripts (sometimes called macros) for Microsoft Windows programs[3] but has since grown to include enhancements in both programming language design and overall functionality.

While the scripting language in AutoIt 1 and 2 was statement-driven, designed primarily for simulating user interaction, from version 3 onwards 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. While version 1 and 2 were compatible with Windows 95, 98, ME, NT4, 2000, XP, 2003, Vista and Windows 7, support for operating systems older than Windows 2000 was discontinued with the release of v3.3.0 in December 2008).[4]

An AutoIt automation script can be converted into a compressed, stand-alone executable which can be run on computers that do not have the AutoIt interpreter installed. A wide range of function libraries (known as UDFs, or "User Defined Functions")[5] 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.

Usage

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.

Examples

Hello world

#include <MsgBoxConstants.au3>

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

Find average

; Find the average of numbers specified by a user e.g. 1,2,42,100,3 etc...

#include <GUIConstantsEx.au3>
#include <StringConstants.au3>

Example()

Func Example()
    ; Create a GUI with various controls.
    Local $hGUI = GUICreate("Find the average of numbers example")

    ; GUI controls.
    GUICtrlCreateLabel("Enter the numbers to find the average of e.g. 1,2,42,100,3", 5, 5, 390, 20) ; There is no requirement to store the id for the label in a variable.
    Local $idNumbers = GUICtrlCreateInput("", 5, 25, 390, 20)
    Local $idAvg = GUICtrlCreateLabel("", 5, 50, 390, 20)
    Local $idFindAvg = GUICtrlCreateButton("Find Avg", 310, 370, 85, 25)

    ; Display the GUI.
    GUISetState(@SW_SHOW, $hGUI)

    ; Variables to hold the answer and @error value returned by FindAvg().
    Local $iAnswer = 0, $iError = 0

    ; Loop until the user exits.
    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE ; When the GUI close button is pressed.
                ExitLoop

            Case $idFindAvg ; When the button is pressed.
                $iAnswer = FindAvg(GUICtrlRead($idNumbers)) ; Read the textbox control and pass as a parameter.
                $iError = @error ; Store the @error value in a temporary variable.
                If Not $iError Then ; If no @error value was returned i.e. zero (0) then set the label control with the average value.
                    GUICtrlSetData($idAvg, $iAnswer)
                Else
                    Switch $iError ; Check the @error value.
                        Case 1
                            GUICtrlSetData($idAvg, "The string was incorrectly formatted and not as 1,2,3 etc...")
                        Case 2
                            GUICtrlSetData($idAvg, "The string contained non-integer values.")

        EndSwitch

    Next
    Local $iAvg = $iSum / $aNumbers[0] ; Divide the sum by the total number of elements.
    Return Floor($iAvg) ; Return the average of all values and round down to the nearest integer.

The developers of AutoIt originally released the source code under the GNU General Public License (GPL), but the practice was discontinued beginning with version 3.2.0 in August 2006. Following the terms of the GPL, some of the code from version 3.1 was used to create a fork by the AutoHotkey project,[8] where the community is continuing to develop and release the code under the GPL.
