MBS Syntax Colorizing saves the day!


We received an email today from Russell Watson and we like to share it with you:

For some reason in our solution some global variables were not being defined …

Where we always define 3 debugging variables ...



… for some reason only one was being defined:



What’s up?

Having first checked everywhere, that three global variables were being defined, we finally got on the track of the bug thanks to the MBS plugin syntax coloring, which was showing an ‘anomaly’ in one of the Let definitions:



Why is the first $ black?

Inspecting the DDR with a text editor which displays control characters (Textmate 2) gave us the final clue:



In the middle of the calculation, just in front of the $$ variable name there are UTF-16 BOM-characters to be found!

(A BOM is a Byte-Order-Mark which usually is only to be found at the very start of a UTF-16 text file, as can be seen when you look at a UTF-16 text file with a hex-editor, for example a DDR file:



The FF identifies the low byte and the FE identifies the high byte … thus the U+FEFF in the editor is the unicode BOM code point)

Editing the calculation to remove and re-enter the whitespace and the first $ symbol cleared the problem:



MBS Plugin happy = We’re happy !

Thank you MBS!
Thank you Christian Schmitz!

Crop a two side page document to a single page document


Have you ever had the problem that you scan documents that’s are printed with two pages on each side and you need this document as a single page Document?

The MBS Xojo Plugins can help you with this problem in Xojo. Our Xojo Plugins includes a GraphicsMagick plugin. With the classes in this plugin you can do a lot of graphic editing, like using graphics effects, add text on an image or crop an image by a given area. Compared to Xojo pictures, we can work even with 16bit color depth here and use exact same functions cross platform.

In this article I want to show you how to cut the pages and set a serial page number at the bottom of each page. At first we load the scanned pictures from a folder to our application. For that we query the folder items to an array. With the method SortedFilesMBS we get an array that is sorted by name already. In the parameters of this method, we can set as the second Parameter that we want to sort the array by filenames. My scanned documents are names Scan_1, Scan_2 and so on.

Dim folder As FolderItem = SpecialFolder.Desktop.Child("Scan")
Dim files() As FolderItem = folder.SortedFilesMBS(False, True, False)

Then we want to loop over this array and cut the pages:

Dim u As Integer = files.Ubound
For i As Integer = 0 To u

We load the current file in two GMImage Objects. One for the Left side (imageL) and one to the right side (imageR). Instead of loading the file twice, we use the copy constructor to get two identical image objects.

Dim imageL As New GMImageMBS(files(i))
Dim imageR As New GMImageMBS(imageL) // copy constructor

If no exception is raised, we determine the height and width of the target pictures. We imagine we have a Din A4 paper on which two pages are printed. The long site is at the bottom side. The page is halved on this side. Therefore we need the full height of the sheet but only half the width. The clipping area is defined as GMGeometryMBS object. In the parameters we can defined the height and width of the cropping rectangle and optional the position of the top left edge coordinates. The default position coordinates are 0/0. That’s why we don’t need to set the coordinates for the left mask. For the left side we only need the height and width of the output. The right side has the same size but the x position is different. It is the half of the long bottom page side and that is w.

Dim h As Integer = imageL.height
Dim w As Integer = imageL.width / 2
Dim geoL As New GMGeometryMBS(w, h)
Dim geoR As New GMGeometryMBS(w, h, w, 0)

With the method crop we cut out the pages.

imageL.crop(geoL)
imageR.crop(geoR)

Then we want to write a page number in the bottom of each page. For drawing on a GMImage we set a graphic object as a property of the image.Then we set the color, the stroke width and the font, before we setting the text and the position of the page number. Afterwards we can draw the page number to the image. We need to take care about the stroke width, because if the value is too big the number is no longer legible. We need to calculate the text of the page number. With each loop run we manage two pages, we multiply it with two. Our variable i starts at 0, but our first left side has the number 1. That's why we add 1 for the left side and add 2 for the right side. For this reason we have for the left side the formula: I * 2 + 1 and for the right side the formula I * 2 + 2.

The code for the right page number looks similar.

Dim drawL As GMGraphicsMBS = imageL.Graphics
drawL.strokeColor(New GMColorRGBMBS("black"))
drawL.strokeWidth(1)
drawL.Font("/Library/Fonts/Verdana.ttf")
drawL.Text(w / 2, h - 100, str(i * 2 + 1))
drawL.Draw

Next we set the format of the image, create folder items and save the images on our desktop in a folder named “Output”, creating it if necessary.

imageL.magick = "PNG"
imageR.magick = "PNG"
Dim Output as folderitem = SpecialFolder.Desktop.Child("Output")
Output.CreateAsFolder
Dim sl As FolderItem = Output.Child(Str(i) + "a.png")
Dim sr As FolderItem = Output.Child(Str(i) + "b.png")

imageL.write(sl)
imageR.write(sr)
Next

I hope that you like this example. We wish you lots of fun with the GraphicsMagick classes and functionalities. If you have any questions, please do not hesitate to contact us.

The new JSON.EqualContent function


Since version 10.0, released in January 2020, the MBS Plugin includes a new JSON function: JSON.EqualContent. This function checks whether two JSON texts have equal content. This function should not be mixed up with the JSON.Equals function, which checks if type and value are the same.

We want to compare the two functions directly. We have the values “123” as String and 123 as number. The values have the same content but different datatypes. If we write in the Script MBS( "JSON.Equals"; "\"123\""; "123") the result is 0 and that means that the parameter are not equal as data types don't match. If we pass both values to the JSON.EqualContent function the result would be 1, so the values are equal

MBS( "JSON.EqualContent"; "\"123\""; "123") => 1
MBS( "JSON.Equals"; "\"123\""; "123") => 0

We wish you much fun with this function. Let us know if you have questions about our MBS Plugin and the JSON functions.

Xojo developer meeting in New York City


The Xojo.Connect conference will take place March 25-27 in Nashville, TN. On our way to Nashville we stop in New York for a few days and we like to organize another Xojo developer meeting, this time in New York City.

Date set: 20th March 2020.
Please email us if you like to be added to the guest list.

We meet in a nice restaurant somewhere in New York City, so we can shop talk about Xojo and have dinner together. Time will probably be around 18 to 22 o'clock and you can of course come later or leave earlier.

If you are interested in private time for consulting, training or discussion MBS or Xojo topics, we can of course schedule a meeting. Please contact me directly interested.

Upcoming deprecations for MBS FileMaker Plugin


There are some deprecations and removals coming for the FileMaker platform and we may follow with the MBS Plugin. Currently we would like to learn who uses deprecated technologies and continues to need updated plugins from us in the future:

FileMaker Pro runtimes
Deprecated in version FileMaker 14, currently available in version 18 and probably gone for version 19.

Windows 32-bit
The number of people using 32-bit versions of Windows is falling quickly. Newer computers bought are 64-bit and come with a 64-bit Windows version. The roadmap for FileMaker shows 32-bit support on Windows as deprecated. FileMaker 19 may drop 32-bit support for Windows as it is not listed as supported feature for the New Claris support policy.

MacOS 32-bit
Since FileMaker version 14, FileMaker supports 64-bit on MacOS, so there hasn't been a request for a 32-bit plugin in some time.

FileMaker Cloud for AWS
The newer FileMaker Cloud 2.x does not have plugin support and the older 1.x Cloud is scheduled to have end of live at the end of calendar year 2021 (or a day later with 1st Jan 2022).

FileMaker 16 and 17
Those FileMaker versions have support end set to September 2020. See New Claris support policy

Windows versions 7.0 and 8.0
The New Claris support policy shows Windows 8.1 as lowest version for Windows.

If you are still interested in newer plugin versions and licenses for those items, please contact us or use this survey. We will manage a list here for the people needing features. In future we may produce a few more versions including support for the items listed above for some time, then drop a few and eventually concentrate on the newer versions only.

Multithreaded JavaScript usage


We got some interest from customers about our JavaScriptEngineMBS class and requests for better Memoryblock handling and threading. So for next prerelease of our 20.1 plugins, we include better handling of Memoryblocks. You can pass a memory block to JavaScript and receive a Memoryblock back. Either with using global properties or as parameter/result of a function or evaluate call. The data in the Memoryblock is copied and available in JavaScript as an UInt8 buffer of the matching size. We add GlobalMemoryBlock() to help you and pass a memory block which is then used by reference, so data is not copied and JavaScript can directly edit the memory from Xojo.



Combine this with our new EvaluateMT and CallFunctionMT methods and you can run various JavaScript codes on preemptive threads in the background and get all CPU cores busy. Our screenshot above shows 8 threads running the function to do the image effect 100 times.

Please makes sure the memory blocks are not released too early and you use one JavaScriptEngineMBS object per thread to keep things separated. If you access a JavaScriptEngineMBS object on two threads, we now raise an exception telling you the object is busy. Even if you use only one thread with one instance, you can keep your GUI responsive while JavaScript runs in background. Using Print and Input events or Xojo delegate method calls, it may talk to your main thread and the GUI. (more)

Merge PDF with table of contents


We got a new example database to show how to merge PDFs. One of the feature beside adding page numbers is to build a table of contents for the document with clickable entries:

Set Variable [ $pdf ; Value: MBS("DynaPDF.New") ] 

#

# create dummy page for table

Set Variable [ $r ; Value: MBS("DynaPDF.AppendPage"; $pdf) ] 

Set Variable [ $r ; Value: MBS("DynaPDF.EndPage"; $pdf) ]

End If

Else

# no PDF?

End If

# check if we have pages to import

Set Variable [ $pageCount ; Value: MBS( "DynaPDF.GetImportPageCount"; $PDF ) ] 

If [ $pageCount > 0 ] 

Set Variable [ $lastPage ; Value: MBS("DynaPDF.ImportPDFFile"; $pdf; $destpage) ] 

If [ GetAsNumber($lastPage) >0 ]

Reading JPEG Thumbnails from EXIF


For next MBS Xojo Plugins we add new methods to JPEGImporterMBS class to read thumbnail from EXIF data in a JPEG file. This allows you to very quickly get a thumbnail image. We support ScaleFactor property for some years now, which allows you to read a JPEG scaled down and get only the pixel data decompressed you need. We use this often for a preview. The time differences may be for a test image here: 5.6 milliseconds for the thumbnail at 160x120, 64 milliseconds for a preview at 504x378 and 276 milliseconds for full image at 4032x3024 pixels. So in your projects, if you need to show JPEGs quickly, you may first check for a thumbnail, then for a scaled down preview and only if user double click the entry load the whole picture.

Here some sample code:

Dim file As FolderItem = SpecialFolder.Desktop.Child("test.jpg") // first read header and check for thumbnail in EXIF Dim j As New JPEGImporterMBS j.file = file j.ReadExifData = True If j.ReadHeader Then Dim thumbnailData As String = j.ExifThumbnail If thumbnailData.LenB > 0 Then thumbnailPic = picture.FromData(thumbnailData) End If // now read a scaled down image Dim factor As Double = Min( j.Height / 300.0, j.Width / 300.0) If factor >= 8.0 Then j.ScaleFactor = 8 Elseif factor >= 4.0 Then j.ScaleFactor = 4 Else j.ScaleFactor = 2 End If j.Import Pic2 = j.Picture // finally read full image j.ScaleFactor = 0 j.Import Pic3 = j.Picture Else MsgBox j.ErrorMessage End If
Coming soon for MBS Plugins version 20.1pr5. See also CGImageSourceMBS class for MacOS to get quickly thumbnails for various image formats.

Upgrading WebKit for Windows support


As you may have seen Xojo 2019r3 uses a newer version of Chromium Embedded Framework for WebKit support on Windows. For us this means we have to put the upgrade of our Chromium plugin classes on the todo list.

For MBS Xojo Plugins 20.1 we upgrade our Chromium classes. You can try it with the recent 20.1pr4 pre-release version.

The changes include a few fixes for ChromiumCookieManagerMBS and ChromiumWebPluginInfoMBS class which both had crashing bugs, but seem to work fine now. You guys can be happy to use a high level language like Xojo where the compiler always makes sure your delegates have the right parameters as any mismatch can cause hard to track bugs later. Luckily we fixed it and now leverage C++ compiler to test those, too.

With newer plugin you can use Chromium with all Xojo versions since the introduction of WebKit support. We now support 3 different versions of the Chromium Embedded Framework used by Xojo with the same plugin. When you start using the plugin classes, we check which CEF version is used and use the right function pointers. Enjoy!

Improve your work live balance with do not disturb


To improve the balance between work and live, some simple things can help:

First, it's a great idea to set a rule in the household to have no phones for meals. So I just leave my iPhone in the office, so it doesn't grab my attention. Some families have baskets for the phones so when you enter kitchen, you put it there. We'll see if we do this when our children get older and we get more devices.

Next figure out the time you allow others to disturb you. The default setting for iOS is to be silent between 22:00 at night and 7:00 o'clock in the morning. Now it seems to work better for me to move those times to 20:00 and 9:00 o'clock. In the morning I may get up long before 9, but to get ready, have breakfast and read through emails, it may be 9 when I am ready to take calls.

For the evening it's difficult alone to get away from work and not work till midnight, but at least the iPhone won't disturb me when I am busy doing some focused work, or watch a movie with my family.

What do you do to get some rest from screens?

Multithreaded plugin functions can increase speed of Xojo application


Have you seen the "NSImageMBS multithreading" or "Threaded Encryption and Hashes" example projects in Xojo?


Do you notice that with 4 Xojo threads, the plugin can actually get 4 CPU cores busy and get work done faster?

Over the last releases we added quite a few MT methods. Those are plugin methods which perform work on a preemptive thread. The Xojo thread calling them yields CPU time to other threads while it waits for the preemptive thread to finish work. And if you use several threads in Xojo already, this will help you keep more CPU cores busy. (more)

Automate login to FileMaker Admin Console in web viewer


Today a client asked how to automate login to the admin console when it is open in a web viewer within a FileMaker solution. You probably saw the video Automate web viewer already?

The login here is a bit more difficult as you need a couple of JavaScript calls to login, but here is a script that works for us:

Set Variable [ $JS ; Value: "
function SendEvent(o, name)
{
  // send event to JavaScript event listeners¶
  var evt = document.createEvent('Events');
  evt.initEvent(name, true, true);
  o.dispatchEvent(evt);
}

// set user name¶
o = document.getElementById('inputUserName');
o.focus();
o.value = '" & Admin Console::Username & "';
SendEvent(o, 'input');
SendEvent(o, 'blur');

// set password¶
o = document.getElementById('inputPassword');
o.focus();
o.value = '" & Admin Console::Password & "';
SendEvent(o, 'input');
SendEvent(o, 'blur');

document.getElementById('LOGN_Butn_SignIn').click();" ]
Set Variable [ $r ; Value: MBS("WebView.RunJavaScript"; "web"; Substitute ( $JS; ¶; Char(10) )) ]

As you see we define an utility function in JavaScript to trigger an event programmatically. This is required as the login form has event listeners in JavaScript which validate the fields and we need those to enable the Sign In button for us. we do the following steps for each field. We query the field by its ID, set the focus, enter the text and trigger input event to have the JavaScript recognize the changes and then blur it to remove focus. Finally on the end we trigger a click on the login button.

Please note that for text in a formula FileMaker removes the line breaks, so for each comment we add a ¶ character to indicate we want a line break there. Also we do a replace all here to change line endings to unix line endings before we run it with the WebView.RunJavaScript function.

If you have questions, please don't hesitate to contact us. The example will be included with next plugin version.

Core Location Geocoder with JSON


When we implemented CLGeocoder functions in year 2014, there was not much JSON in use. Nowadays a lot of FileMaker developers deal with JSON data, so why not add more JSON functions to MBS Plugin?

We got a refreshment for our CLGeocoder functions today. For next plugin we first add a wait parameter to CLGeocoder.GeocodeAddressString and CLGeocoder.ReverseGeocodeLocation functions. If wait is 1, the plugin waits a bit until the geocoder is done. Just convenient to avoid having the loop to wait in FileMaker scripts.

Second, we add a CLGeocoder.JSON function to return the data as JSON. This is one big JSON which encodes all the details including status variables, error details and the list of place marks found. For each place mark you get the location, region and address properties.

We can now query address in one Let statement, check status and return the result as JSON:

Let ( [
  Address = "Berlin, Germany";
  // run query and wait a bit
  g = MBS( "CLGeocoder.GeocodeAddressString"; Address; 1 );
  e = MBS("IsError");
  // query JSON if we got something
  r = If (e = 0; MBS( "CLGeocoder.JSON"; g ); g);
  // free resources
  f = If (e = 0; MBS( "CLGeocoder.Close"; g ); 0)
]; r )

Similar let statement for the other way around:

Let ( [
  latitude = 52.517631899999998;
  longitude = 13.4096574;
  // run query and wait a bit
  g = MBS( "CLGeocoder.ReverseGeocodeLocation"; latitude; longitude; 1 );
  e = MBS("IsError");
  // query JSON if we got something
  r = If (e = 0; MBS( "CLGeocoder.JSON"; g ); g);
  // free resources
  f = If (e = 0; MBS( "CLGeocoder.Close"; g ); 0)
]; r )

We add this for next release for your convenience. Please do not hesitate to contact us in case of questions.

You can learn about CURL releases on the curl website.

Why do we care? Well, if you still use FileMaker before version 16, your FileMaker scripts using Insert From URL are affected by the TLS certificate bugs in older CURL versions. And if certificate verification is not done right, someone can attack your queries, gain your password or provide invalid data to your solution. So please keep FileMaker up to date!

As with MBS Plugin, Claris Inc. also regularly updates the open source libraries used. Usually you do that on the begin of the development cycle, so you have time to find and issues from the newer library version like a bug fix, which changes behavior in a way you didn't intent. e.g. we run into CURL change for email download via IMAP.

MBS Plugin 10.1 will include CURL version 7.68.0 and MBS Plugin 10.0 shipped with version 7.67.0.

Customized File Open and Save Dialogs for Windows


This week, I learnt a lot about the APIs from Microsoft for open and save dialogs. For Xojo we got new WinFileOpenDialogMBS and WinFileSaveDialogMBS classes. Both are based on WinFileDialogMBS class and report errors via WinFileDialogExceptionMBS. To return items, we use WinShellItemMBS class and WinShellItemArrayMBS for a list of items. To define file types, we got the WinFileTypeMBS class. The dialog may look like this:



We customized the title, the OK button, the label for the file name and added a list of file types to fill the file types popup menu. As you see there are custom controls on the dialog with two text fields and a checkbox with a popupmenu below. We added a lot of events for the WinFileDialogMBS class, so you not just learn about changed selections, folder changes, but also about events to custom controls. In the CheckButtonToggled event as an example we can react on the checkbox and enable/disable the popupmenu below.

While most people are happy with the built-in OpenFileDialog and SaveFileDialog classes, our plugin classes offer many more features for Windows specific projects. Please check NSOpenPanelMBS and NSSavePanelMBS classes for MacOS to do similar things. And we still have OpenDialogMBS as a cross platform class.

The example project with a lot of settings:



Please try soon with next prerelease of MBS Xojo Plugins 20.1.

Our JavaScript engine, a game changer


Yesterday Sean Beach, one of our clients in New York emailed me back about our JavaScript integration. To quote him:

"Wanted to follow back and say that this plugin is a game changer for my showcontrol product. Thanks so much!”

The discussion was about our JavaScript functions and a couple of his questions got answered in our Tips for our JavaScript functions blog post:

"This document is fantastic, and actually answers most of my questions from the previous email."

We are delighted about the feedback we got!

The same day Stefanie got two of her latest articles published about using JavaScript to calculate distances.

On our FileMaker blog the version using our FileMaker Plugin:
FileMaker and JavaScript - the perfect combination

And even on the official Xojo blog an article about our Xojo class to run JavaScript:
Xojo and JavaScript – A Perfect Combination

We are happy to see that our JavaScript integration is so well received by clients from around the world. And it just started with a hint from one user in early December to take a look into this topic.

Check out the JavaScriptEngineMBS class for Xojo and the JavaScript functions for FileMaker!

20 Years Monkeybread Software Party


This year in April our company will turn 20 years old.
We'll plan to have a big party here in Germany near our office with over 100 guests.

Today we send invitations to guests who have not yet responded.

If you like to join and you miss an invitation, you can contact us and ask whether your invitation got lost.

As people confirm they are coming, we'll add them to the guest list. If we run out of space, we may put people on the wait list.
If you can't make it, please respond soon, so we don't need to contact you again later.

FileMaker and JavaScript - the perfect combination


In the newest version of the MBS FileMaker Plugin 10.0 we offer functions for the use of JavaScript without the use of a web viewer. See WebView.RunJavaScript and WebView.Evaluate to run or evaluate JavaScript in a web viewer. The new JavaScript functions increase your functionality in FileMaker enormously. You can write your own Javascript, use a JavaScript snipped that fix a problem or fast up a process of your solution. In this article I want to show you how to use JavaScript code in FileMaker: Setting values in the JavaScript with functions in FileMaker, add functions and run them.

If you have a problem that you want to solve, you don't have to reinvent the wheel again and again. Perhaps someone has already found a solution to this problem and shared his solution on the Internet. So start a search engine and try your luck. Special thanks to André Rinas and his website andrerinas.de that supply very useful JavaScript snippets to everyone. This example is based on one of this JavaScript codes.

Airplay related classes for AVFoundation


For MacOS, we add AVRouteDetectorMBS class to detect if multiple routes are available, e.g. for Airplay.
And for MacOS 10.15 we add AVRoutePickerViewControlMBS control to show the standard control from Apple to select the output device:



If you have an Airplay enabled device, it should show up in the popup menu.
Our example project uses AVRouteDetectorMBS class to detect if multiple routes are available. If that is true, we show the AVRoutePickerViewControlMBS control and let the user pick the destination for the current video player.

Tips for our JavaScript functions


Here a few tips we recently learnt for our JavaScript engine based on Duktape in the MBS Plugins for FileMaker and Xojo:
  1. Use performance.now() to get time within JavaScript and measure how long something takes. Here an example where we measure how many milli seconds it takes to run a loop one million times:
    function testFunction() {
        for (var i = 0; i < 1e6; i++) {}
    }
    
    var t1 = performance.now();
    testFunction();
    var t2 = performance.now();
    
    Print('test took: ' + (t2 - t1) + ' milliseconds');
  2. All global functions and properties in JavaScript are attached to the global object. You can access them explicitly via globalThis keyword.
  3. List global properties via JavaScript:
    Var list = Object.keys(globalThis);
    The list will include all global names including functions like Print registered by MBS Plugin.
  4. Check Duktape.version for the version number. If we update the engine, you can check the version number and compare. Currently the value is 20500 for version 2.5.
  5. Use unicode escapes in strings if needed to mask special characters. While the engine handles UTF-8 fine, you can escape some characters with \u followed with a hex 4 digit number, e.g.
  6. n = '\u0041';
    Which will assign "A" to variable n.
  7. Use built-in functions to encode text as hex or base64 via Duktape.enc:
    Duktape.enc('base64', 'Hello')
    This returns "SGVsbG8=".
  8. Use Duktape.dec and TextDecoder class to decode base64/hex encoded text to UTF-8 string:
    var result = new TextDecoder().decode(Duktape.dec('base64', 'Zm9v'));
    Result is now a variable with text "foo".
  9. Access call stack with Duktape.act function. Query Duktape.act(i) with various values of i. Pass -1 for the act() call, -2 for the current function and -3 for the caller of current function. The returned object contains properties for lineNumber and function. When you query function.name, you get the name of the function.
  10. Add console object if needed. You can add a console object and include a log function, which sends arguments to a Print function:
    console = { log: function() { Print(Array.prototype.join.call(arguments, ' ')); } };
  11. Provide environment some JavaScript may need. If some JavaScript expects a global window object to store something, you can simply create a dummy one:
    window = {};
    This may not provide functionality, but allows at least code to check for this to work.
  12. Prefer functions over evaluating code. Code in functions is parsed and uses registers for the virtual machine, while code evaluated may use named variables, so if you can put your code in a function and just evaluate the function call, things may execute a bit faster.
  13. Be aware all numbers in JavaScript are doubles. Evaluate "9999999999999999" and you get "10000000000000000" back. Comparing numbers may not give the result you expect as "0.1+0.2==0.3" evaluates to false.
If you have questions, please do not hesitate to contact us. See also JS.Evaluate and related JavaScript functions in MBS FileMaker Plugin and JavaScriptEngineMBS class in MBS Xojo Plugins.
