Lambda expressions - A really rough sketch.

Recommended Posts

If you are coming from the realm of C# 3.0 then lamda expressions should be pretty familiar to you as it's basic syntactic sugar for creating a function with a conditional return.

 

Since functions in AutoIt are first class objects, the following code should make some sense. It passes an array of integers to a function called IsTrueForAll() that checks whether the function object matches the return condition of that function (you passed). So for example a function called IsGreaterThanOrEqualTo10() checks if all values are greater than or equal to 10 (TRUE). Similarly, IsLessThan10() checks if all values are less than 10 (FALSE). This example should be nothing new to those of you who use v3.3.10.0+ and have an understanding of Call().

#include <MsgBoxConstants.au3>

Local $aArray[] = [10, 100, 99, 67]
If IsTrueForAll($aArray, IsGreaterThanOrEqualTo10) Then
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was True.')
Else
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was False')
EndIf

If IsTrueForAll($aArray, IsLessThan10) Then
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was True.')
Else
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was False')
EndIf

Func IsTrueForAll($aArray, $hFunc) ; Loop through the array and check the function passed with a single param matches the condition.
    For $i = 0 To UBound($aArray) - 1
        If Not $hFunc($aArray[$i]) Then
            Return False
        EndIf
    Next
    Return True
EndFunc   ;==>IsTrueForAll

Func IsGreaterThanOrEqualTo10($x)
    Return  $x >= 10
EndFunc ;==>IsGreaterThanOrEqualTo10

Func IsLessThan10($x)
    Return  $x < 10
EndFunc ;==>IsLessThan10
But, we could easily just forget about writing the functions (less typing is always nice) and let the compiler or pre-processor do all the work for us. It would simply use the lambda expression and create the function for us with whatever we specified. Like so...

#include <MsgBoxConstants.au3>

Local $aArray[] = [10, 100, 99, 67]
If IsTrueForAll($aArray, $x => $x >= 10) Then ; $x is the parameter, => tells us it's a lambda expression and then the condition we are checking.
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was True.')
Else
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was False')
EndIf

If IsTrueForAll($aArray, $x => $x < 10) Then ; $x is the parameter, => tells us it's a lambda expression and then the condition we are checking.
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was True.')
Else
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was False')
EndIf

Func IsTrueForAll($aArray, $hFunc) ; Loop through the array and check the function passed with a single param matches the condition.
    For $i = 0 To UBound($aArray) - 1
        If Not $hFunc($aArray[$i]) Then
            Return False
        EndIf
    Next
    Return True
EndFunc   ;==>IsTrueForAll
...which would create the following code with anonymous functions (they're anonymous as we don't care about them in our main script)...

#include <MsgBoxConstants.au3>

Local $aArray[] = [10, 100, 99, 67]
If IsTrueForAll($aArray, D3F7B1B92177415CA70C7FFC35C2649C) Then
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was True.')
Else
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was False')
EndIf

If IsTrueForAll($aArray, DA06B548ABF4045AA32F805E6651004) Then
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was True.')
Else
    MsgBox($MB_SYSTEMMODAL, '', 'Condition was False')
EndIf

Func IsTrueForAll($aArray, $hFunc)
    For $i = 0 To UBound($aArray) - 1
        If Not $hFunc($aArray[$i]) Then
            Return False
        EndIf
    Next
    Return True
EndFunc   ;==>IsTrueForAll

Func D3F7B1B92177415CA70C7FFC35C2649C($x)
    Return  $x >= 10
EndFunc ;==>D3F7B1B92177415CA70C7FFC35C2649C

Func DA06B548ABF4045AA32F805E6651004($x)
    Return  $x < 10
EndFunc ;==>DA06B548ABF4045AA32F805E6651004

The saying is old code should run new code, therefore we don't need to change the function IsTrueForAll(), just the function we pass which contains the condition we are checking.

Funnily enough I was thinking of mentioning this to you, as you'd already written a preprocessor capable of this.

C# lambdas a quite complex when you get to how they deal with variables used within them. For example look at the following code:

delegate int MulByDelegate(int x);

        static void Main(string[] args)
        {
            MulByDelegate mul1;
            MulByDelegate mul2;

            {
                int mulBy = int.Parse(Console.ReadLine());

                mul1 = (x => x * mulBy);
            }

            {
                int mulBy = int.Parse(Console.ReadLine());

                mul2 = (x => x * mulBy);
            }

            Console.WriteLine("mul1 = {0}", mul1(5));
            Console.WriteLine("mul2 = {0}", mul2(5));
            Console.ReadKey();
        }

This demonstrates that lambdas are first class objects, and are created at runtime. As you'd expect, mul1 does multiplication by the first number you input and mul2 by the second.

Now try this very similar code:

delegate int MulByDelegate(int x);

        static void Main(string[] args)
        {
            MulByDelegate mul1;
            MulByDelegate mul2;

            {
                int mulBy = int.Parse(Console.ReadLine());

                mul1 = (x => x * mulBy);

                mulBy = int.Parse(Console.ReadLine());

                mul2 = (x => x * mulBy);
            }

            Console.WriteLine("mul1 = {0}", mul1(5));
            Console.WriteLine("mul2 = {0}", mul2(5));
            Console.ReadKey();
        }

The only difference is that instead of the mulBy variable going out of scope then being re-declared, it is reused. Now both lambdas should be the same. 

The variable mulBy is captured, rather than just substituted in.

When you disassemble the C# code for the latter, you'll find there is actually a new static class created, called c__DisplayClass2 or something like that, which has mulBy as a member variable. When looking at the byte code of the former you'll see two classes with names like that, both with their own mulBy member.

This page may go some way towards explaining the behaviour and its uses.

1. I didn't think about using { } as you did. My mind is quite literally blown.

2. Maybe I am not seeing what you're seeing, because I am using ILSpy.

 

1st

private static void Main(string[] args)
{
    int mulBy2 = int.Parse(Console.ReadLine());
    Program.MulByDelegate mul = (int x) => x * mulBy2;
    int mulBy = int.Parse(Console.ReadLine());
    Program.MulByDelegate mul2 = (int x) => x * mulBy;
    Console.WriteLine("mul1 = {0}", mul(5));
    Console.WriteLine("mul2 = {0}", mul2(5));
    Console.ReadKey();
}
2nd

private static void Main(string[] args)
{
    int mulBy = int.Parse(Console.ReadLine());
    Program.MulByDelegate mul = (int x) => x * mulBy;
    mulBy = int.Parse(Console.ReadLine());
    Program.MulByDelegate mul2 = (int x) => x * mulBy;
    Console.WriteLine("mul1 = {0}", mul(5));
    Console.WriteLine("mul2 = {0}", mul2(5));
    Console.ReadKey();
}

IlSpy is too clever, you need to look at the actual byte code. Should be a program called Ildasm in the start menu (it's installed with visual studio).

Even then, the first one is actually changed. Notice how there are now two different variables names rather than one being reused! That actually displays the difference very nicely.

I looked at the IL code as well, but I am way too tired right now. Tomorrow I will look and understand.

      var au = new AutoItX3Class(); I got this error message: Interop type 'AutoItX3Class' cannot be embedded. Use the applicable interface instead.
      My system info:
      Visual Studio 2017 Enterprise - v15.5.4
      X64 Windows 10 Enterprise 1607
      Thanks in advanced

      Not one usually to post non-AutoIt things, but as I have this question on StackExchange I thought I would throw it up here as well for any of our C# folks:
      I currently have an AutoIt GUI that calls a powershell script; the intent is to allow low-level technicians to batch create VMs in vSphere. Due to some changes in requirements from the customer, I am re-writing as a wpf app. The app itself is complete and working; this is more of a curiosity question.
      I have two methods attached to buttons on the GUI - one to pull all the data out of a listview and export to csv and another to do the reverse; importing from csv to the listview element. I wrote the export first, and went with manipulating the Excel application:
      private void Launch(object sender, RoutedEventArgs e) { Microsoft.Office.Interop.Excel.Application oExcel = new Microsoft.Office.Interop.Excel.Application(); oExcel.Visible = true; Microsoft.Office.Interop.Excel.Workbook oWorkBook = oExcel.Workbooks.Add(Microsoft.Office.Interop.Excel.XlSheetType.xlWorksheet); Microsoft.Office.Interop.Excel.Worksheet oSheet = (Microsoft.Office.Interop.Excel.Worksheet)oExcel.ActiveSheet; int row = 2; //allow for header row int column = 1; oSheet.Cells[1, 1] = "Name"; oSheet.Cells[1, 2] = "CPU"; oSheet.Cells[1, 3] = "RAM"; oSheet.Cells[1, 4] = "IP Address"; oSheet.Cells[1, 5] = "Subnet Mask"; oSheet.Cells[1, 6] = "Port Group"; oSheet.Cells[1, 7] = "Default Gateway"; oSheet.Cells[1, 8] = "DNS"; oSheet.Cells[1, 9] = "Description"; oSheet.Cells[1, 10] = "Template"; oSheet.Cells[1, 11] = "Host"; oSheet.Cells[1, 12] = "Site"; oSheet.Cells[1, 13] = "Folder"; oSheet.Cells[1, 14] = "DataStore"; oSheet.Cells[1, 15] = "Patch Method"; oSheet.Cells[1, 16] = "HDD1Size"; oSheet.Cells[1, 17] = "HDD1Format"; oSheet.Cells[1, 18] = "HDD2Size"; oSheet.Cells[1, 19] = "HDD2Format"; oSheet.Cells[1, 20] = "HDD3Size"; oSheet.Cells[1, 21] = "HDD3Format"; oSheet.Cells[1, 22] = "HDD4Size"; oSheet.Cells[1, 23] = "HDD4Format"; oSheet.Cells[1, 24] = "HDD5Size"; oSheet.Cells[1, 25] = "HDD5Format"; foreach (var oVM in MyItems) { oSheet.Cells[row, column] = oVM.Name; oSheet.Cells[row, (column + 1)] = oVM.CPU; oSheet.Cells[row, (column + 2)] = oVM.RAM; oSheet.Cells[row, (column + 3)] = oVM.IP; oSheet.Cells[row, (column + 4)] = oVM.Subnet; oSheet.Cells[row, (column + 5)] = oVM.PortGroup; oSheet.Cells[row, (column + 6)] = oVM.Gateway; oSheet.Cells[row, (column + 7)] = oVM.DNS; oSheet.Cells[row, (column + 8)] = oVM.Description; oSheet.Cells[row, (column + 9)] = oVM.Template; oSheet.Cells[row, (column + 10)] = oVM.Host; oSheet.Cells[row, (column + 11)] = oVM.Site; oSheet.Cells[row, (column + 12)] = oVM.Folder; oSheet.Cells[row, (column + 13)] = oVM.Datastore; oSheet.Cells[row, (column + 14)] = oVM.Patch; oSheet.Cells[row, (column + 15)] = oVM.HDD1Size; oSheet.Cells[row, (column + 16)] = oVM.HDD1Format; oSheet.Cells[row, (column + 17)] = oVM.HDD2Size; oSheet.Cells[row, (column + 18)] = oVM.HDD2Format; oSheet.Cells[row, (column + 19)] = oVM.HDD3Size; oSheet.Cells[row, (column + 20)] = oVM.HDD3Format; oSheet.Cells[row, (column + 21)] = oVM.HDD4Size; oSheet.Cells[row, (column + 22)] = oVM.HDD4Format; oSheet.Cells[row, (column + 23)] = oVM.HDD5Size; oSheet.Cells[row, (column + 24)] = oVM.HDD5Format; row++; } oExcel.Application.ActiveWorkbook.SaveAs(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + "\\example", 6); } It works, but it is slow. I have Excel set to visible for testing, and it is a good 6 or 7 seconds on a pretty high end box before the app even pops up.  It then takes another 2 seconds to populate 11 rows (this could be in the hundreds of rows at some point).
      I then wrote the code for the reverse, and decided to try a StreamReader object. The result, surprisingly, was almost immediate:
      OpenFileDialog xls = new OpenFileDialog(); xls.Multiselect = false; xls.Filter = "CSV files (*.csv)|*.csv"; xls.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); xls.ShowDialog(); string ins; if (xls.FileName != null) { FileStream srcFS; srcFS = new FileStream(xls.FileName, FileMode.Open); StreamReader srcSR = new StreamReader(srcFS, System.Text.Encoding.Default); do { ins = srcSR.ReadLine(); if (ins != null) { string[] parts = ins.Split(','); MyItems.Add(new MyItem { Name = parts[0], CPU = parts[1], RAM = parts[2], IP = parts[3], Subnet = parts[4], PortGroup = parts[5], Gateway = parts[6], DNS = parts[7], Description = parts[8], Template = parts[9], Host = parts[10], Site = parts[11], Folder = parts[12], Datastore = parts[13], Patch = parts[14], HDD1Size = parts[15], HDD1Format = parts[16], HDD2Size = parts[17], HDD2Format = parts[18], HDD3Size = parts[19], HDD3Format = parts[20], HDD4Size = parts[21], HDD4Format = parts[22], HDD5Size = parts[23], HDD5Format = parts[24] }); } } while (ins != null); srcSR.Close(); } }  
      So, I thought I would go back and change the export to use the same method:
      FileStream srcFS; srcFS = new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + "\\testingout.csv", FileMode.CreateNew, FileAccess.Write); StreamWriter srcWrt = new StreamWriter(srcFS, System.Text.Encoding.Default); StringBuilder header = new StringBuilder(); header.Append("Name").Append(',') .Append("CPU").Append(',') .Append("RAM").Append(',') .Append("IP Address").Append(',') .Append("Port Group").Append(',') .Append("Default Gateway").Append(',') .Append("DNS").Append(',') .Append("Description").Append(',') .Append("Template").Append(',') .Append("Host").Append(',') .Append("Site").Append(',') .Append("Folder").Append(',') .Append("Datastore").Append(',') .Append("Patch").Append(',') .Append("HDD1Size").Append(',') .Append("HDD1Format").Append(',') .Append("HDD2Size").Append(',') .Append("HDD2Format").Append(',') .Append("HDD3Size").Append(',') .Append("HDD3Format").Append(',') .Append("HDD4Size").Append(',') .Append("HDD4Format").Append(',') .Append("HDD5Size").Append(',') .Append("HDDFormat").Append(','); srcWrt.WriteLine(header); foreach (MyItem item in MyItems) { StringBuilder builder = new StringBuilder(); builder.Append(item.Name).Append(',') .Append(item.CPU).Append(',') .Append(item.RAM).Append(',') .Append(item.IP).Append(',') .Append(item.Subnet).Append(',') .Append(item.PortGroup).Append(',') .Append(item.Gateway).Append(',') .Append(item.DNS).Append(',') .Append(item.Description).Append(',') .Append(item.Template).Append(',') .Append(item.Host).Append(',') .Append(item.Site).Append(',') .Append(item.Folder).Append(',') .Append(item.Datastore).Append(',') .Append(item.Patch).Append(',') .Append(item.HDD1Size).Append(',') .Append(item.HDD1Format).Append(',') .Append(item.HDD2Size).Append(',') .Append(item.HDD2Format).Append(',') .Append(item.HDD3Size).Append(',') .Append(item.HDD3Format).Append(',') .Append(item.HDD4Size).Append(',') .Append(item.HDD4Format).Append(',') .Append(item.HDD5Size).Append(',') .Append(item.HDD5Format); srcWrt.WriteLine(builder); } MessageBox.Show("Task Complete"); What surprised me is this method is exponentially slower; on the order of 40 seconds to return the MsgBox. I also noticed that even though the loop is complete and shows the message, is seems the stream is still writing. If I open the file too quickly it shows that it is still in use by "Another User". So by the time the file is available to me it is actually closer to a minute for an 11-line csv.
      I'm just curious at the difference in speed read vs write using FileStream. Is it something I borked on implementation (eminently possible) or is this a known issue? If interacting with Excel is the way to go (not ideal) is there something I could do to shorten the initial lag?

      Greetings, someone can give a exemple, how send a error from a C#'s dll to AutoIt?
      I use this line, to send an error... but, I want get a error code In AutoIt with macro @error, it's possible?
       
      throw new ArgumentException("arquivo map não existe", "value" ); In this way, work, I know ther are error, but, @errror always is zero.
      I don't want this, I want a number as error code.
      Can you help me?
       
      Best regards

      AutoIT AU3info doeas not detect all gui objects uniquely for .NET GUIs developed in C#.
      this is not working now i am using COM windows approach for this, But its very difficult.
      Please let me know if anyone has done it before.

      What's the best way to receive file from a desktop app?
      app.exe will execute a cmd with "au3file.exe /path/of/the/file.xml" and the au3file.exe will get and delete that. Or else? THE MOST IMPORTANT PART OF THE QUESTION
      And best way to transfer file to a desktop app?
      au3file.exe do a $_POST request and the app.exe MUST HAVE a local HTTP server that can receive $_POST, but it looks heavy 'cause the app must have a server such XAMPP. au3file.exe execute a cmd with "app.exe /path/of/the/file.xml" and the app.exe will now get that file and delete. Or else?
