is there a way to pass an array to a function directly like function(["one","two","three"])?

In some cases I don't have to use the array outside the the function so I would like to avoid to do an array declaration before calling the function:

local $array = ["one","two","three"]

function($array)

No, I guess Autoit doesnt support that,

why not pass the array and then check the values using a For Loop :huh:


My code:

PredictText: Predict Text of an Edit Control Like Scite. Remote Gmail: Execute your Scripts through Gmail. StringRegExp:Share and learn RegExp.

Run As System: A command line wrapper around PSEXEC.exe to execute your apps scripts as System (LSA). Database: An easier approach for _SQ_LITE beginners.

MathsEx: A UDF for Fractions and LCM, GCF/HCF. FloatingText: An UDF for make your text floating. Clipboard Extendor: A clipboard monitoring tool. 

Custom ScrollBar: Scroll Bar made with GDI+, user can use bitmaps instead. RestrictEdit_SRE: Restrict text in an Edit Control through a Regular Expression.

Like this?

#include <Array.au3> ; For ArrayDisplay

Dim $aArray[3]=["1", "2", "3"]

$aString =_ArrayToString($aArray, "|")
$aSplit = StringSplit($aString, "|")
_MyFunc($aArray, "Test")

Func _MyFunc($array, $Par2 = "")
_ArrayDisplay($array,"")
MsgBox(0, 0, $array[0])
MsgBox(0, 0, $Par2)
EndFunc

Two things:

Dim should regarded as obsolescent. Prefer using Local or Global depending on requirements.

Arrays can be costly to copy (AutoIt uses copy on write but anyway). Pass arrays ByRef (see help).

Recommended option: use the Const modifier as appropriate.

is there a way to pass an array to a function directly like function(["one","two","three"])?

In some cases I don't have to use the array outside the the function so I would like to avoid to do an array declaration before calling the function:

local $array = ["one","two","three"]

function($array)

Maybe ByRef ? From the helpfile:

Example1()
Example2()

; example1
Func Example1()
; Sample script with three user-defined functions
; Notice the use of variables, ByRef, and Return

Local $foo = 2
Local $bar = 5
MsgBox(0, "Today is " & today(), "$foo equals " & $foo)
swap($foo, $bar)
MsgBox(0, "After swapping $foo and $bar", "$foo now contains " & $foo)
MsgBox(0, "Finally", "The larger of 3 and 4 is " & max(3, 4))
EndFunc ;==>Example1

Func swap(ByRef $a, ByRef $b) ;swap the contents of two variables
Local $t
$t = $a
$a = $b
$b = $t
EndFunc ;==>swap

Func today() ;Return the current date in mm/dd/yyyy form
Return (@MON & "/" & @MDAY & "/" & @YEAR)
EndFunc ;==>today

Func max($x, $y) ;Return the larger of two numbers
If $x > $y Then
Return $x
Else
Return $y
EndIf
EndFunc ;==>max

;End of sample script 1

; example2
Func Example2()
; Sample scriptusing @NumParams macro
Test_Numparams(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
EndFunc ;==>Example2

Func Test_Numparams($v1 = 0, $v2 = 0, $v3 = 0, $v4 = 0, $v5 = 0, $v6 = 0, $v7 = 0, $v8 = 0, $v9 = 0, _
$v10 = 0, $v11 = 0, $v12 = 0, $v13 = 0, $v14 = 0, $v15 = 0, $v16 = 0, $v17 = 0, $v18 = 0, $v19 = 0)
#forceref $v1, $v2, $v3, $v4, $v5, $v6, $v7, $v8, $v9, $v10, $v11, $v12, $v13, $v14, $v15, $v16, $v17, $v18, $v19
Local $val
For $i = 1 To @NumParams
$val &= Eval("v" & $i) & " "
Next
MsgBox(0, "@NumParams example", "@NumParams =" & @NumParams & @CRLF & @CRLF & $val)
EndFunc ;==>Test_Numparams

imbuter2000,

I would like to avoid to do an array declaration before calling the function:

Why? If you explain your purpose there may be other alternatives.

kylomas

edit: additional info

This

#include <array.au3>
_1('123')
func _1($prm)
 local $array = stringsplit($prm,'')
 _arraydisplay($array)
endfunc

and/or variations of what J1 posted are as close as you are likely to get.

If the arguments will never change then here is a way (no pun intended):

Func my_awesome_function()
    Local Const $my_awesome_array[3] = [1, 2, 3]
    
    ; do things
EndFunc
