How to return and use result of StringSplit?

27 Aug 2016, 14:42

I am reading the contents of a file that I drag onto my AHK script to extract some data from it. All of that works fine, the ArgumentsArray in the ExtractAction contains all the data I want at the end of the function but when I want to use the returned data of the method it says it's size is 2 but when I want to access the data it is empty.

Here is the code.

Code: Select all

ExtractAction(Action, Contents) {
    RegExMatch(Contents, "%Action%((.*))", ActionResult)
    RegExMatch(ActionResult, "\((.*?)\)", parenthesis)

    StringReplace, parenthesis, parenthesis, (, ``, All
    StringReplace, parenthesis, parenthesis, ), ``, All

    StringSplit, ArgumentsArray, parenthesis, `,`

    Loop, %ArgumentsArray0%
    {
        ArgumentsArray%a_index% := RemoveInvalidCharacters(ArgumentsArray%a_index%)
    }

    MsgBox, %ArgumentsArray0% ; ArgumentsArray0 size is 2, ArgumentsArray1 and ArgumentsArray2 contain what I want

    return %ArgumentsArray0%
}

Loop %0% {
    GivenPath := %A_Index%

    Loop %GivenPath%, 1
        FilterFile = %A_LoopFileFullPath%

    FileRead, Contents, %FilterFile%

    result := ExtractAction("ActionName", Contents) ; result will be ArgumentsArray0

    MsgBox, %result1% ; result0 size is 2, result1 and result2 are empty
}

Don't use pseudo arrays for function returns.

Code: Select all

ExtractAction(Action, Contents) {
    RegExMatch(Contents, "%Action%((.*))", ActionResult)
    RegExMatch(ActionResult, "\((.*?)\)", parenthesis)

    StringReplace, parenthesis, parenthesis, (, ``, All
    StringReplace, parenthesis, parenthesis, ), ``, All

    StringSplit, ArgumentsArray, parenthesis, `,`
    myarray:=[]

    Loop, %ArgumentsArray0%
    {
        myarray[a_index] := RemoveInvalidCharacters(ArgumentsArray%a_index%)
    }

    msgbox % myarray[0] "`n" myarray.1 "`n" myarray.2

    return myarray
}
result:=[]

Loop %0% {
    GivenPath := %A_Index%

    Loop %GivenPath%, 1
        FilterFile = %A_LoopFileFullPath%

    FileRead, Contents, %FilterFile%

    result := ExtractAction("ActionName", Contents) 

    MsgBox, % result.0 "`n" result.1 "`n" result.2 
}
