if the parameter is optional and you do not want to exercise your option with one of the optional parameters then use double quotes ( "" ) to nullify that parameter in the option. :whistle:


Agreement is not necessary - thinking for one's self is!

Are you talking about Function parameters? if so:

Func _MyFunction($RequiredParam, $NotRequired = "")
;Do something!
EndFunc

$cmdline[0] give you the number of passed parameters so you can check you get o,ly 3 and do what you want :whistle:

Another way is to use $Cmdlineraw and strip out the bits...... ie

$Docopy = "Yes"

$DontDoIt="No"

$RenameDir="Yes"

$Raw=StringReplace($Cmdlineraw,@ScriptFullPath,"") ; take out @ScriptFullPath

if stringinstr($Raw,"No") then $Docopy = "No"

if stringinstr($Raw,"Yes") then $Docopy = "Yes"

if stringinstr($Raw,"DontDoIt") then $DontDoIt = "Yes"

if stringinstr($Raw,"NoRename") then $RenameDir = "No"

;if $Docopy = .......

This way it doesnt matter what order the $cmdline parameters are in,

providing of course that each parameter is unique.

Hope this helps.

Hi, this might help, but... it is untested (a cyber quick-code), I will come with a more detailed, general-use function in a couple of days (I hope :whistle: ):

Func ParseCommandLineParameters()
Local $i
For $i =1 to $CmdLine[0] step 1
select
case "/option1"
; and you can, of course nest some functions, selects, switches and so on, to handle your parameters...
; I usually use the OnEvent Mode (failed to understand the basics of MessageLoop Mode)
case "/option2"
case else
endselect
Next

EndFunc

There is all the code... hope it helps; yesterday's was a one-minute code... It's so buggy (This one is more tested)

Func ParseCommandLineParameters()
    Local $i
;~  first check if it has parameters
    If $CmdLine[0] = 0 Then
;~      here goes the code to handle if it have no parameters
;~      e. g.:
        MsgBox(0, "Error", "No parameters set...")
    Else
;~      if it have one or more than one parameter
;~      this does not check for duplicated parameters, as I do not want to impose that constrain
        For $i = 1 To $CmdLine[0] Step 1
;~          just cycle through the array passed until it reach the last item
            Select
                Case $CmdLine[$i] = "/make"
;~                      you may want to check if the next parameter is properly supplied (in context, as in /make /file=""mifile.txt)
;~                      not allowing to perform some code if certain sequence of parameters is not set
;~                      imagine... /delete /all-files parsed in sequence and not in sequence... the latter does not make any sense
;~                      as it loses its context

;~                      just remember to add one to the iterator to point to it
;~                      and check if it is not out of bounds in the upper limit
;~                      otherwise, just exit your loop or manage this error
;~                      repeat this step for every level you go up

                    $i = $i + 1
                    If $i > $CmdLine[0] Then
                        ConsoleWrite("Error.... out of bonds")
                        ExitLoop
                    EndIf
                    Select
                        Case $CmdLine[$i] = "/american-coffee"
                            ConsoleWrite("American coffee")
                        Case $CmdLine[$i] = "/english-tea"
                            ConsoleWrite("ISO standard cup of tea")
                        Case Else
                            MsgBox(0, "cannot make", "Did you have something to make?")
                    EndSelect
                Case $CmdLine[$i] = "/boil"
                    $i = $i + 1
                    If $i > $CmdLine[0] Then
                        ConsoleWrite("Error.... out of bonds")
                        ExitLoop
                    EndIf
                    Select
                        Case $CmdLine[$i] = "/milk"
                        Case $CmdLine[$i] = "/water"
                        Case $CmdLine[$i] = "/alcohol"
                    EndSelect
                Case $CmdLine[$i] = "/bake"
            EndSelect
;~          ConsoleWrite("nothing specified")
        Next
;~      here goes the code to handle if no match have been found
;~      here goes the code to handle if no match have been found
;~      here goes the code to handle if no match have been found
;~      here goes the code to handle if no match have been found
    EndIf
EndFunc   ;==>ParseCommandLineParameters
