Query current found set with Execute FileMaker Data API as JSON

Today we have a tip for you without using MBS FileMaker Plugin and in pure FileMaker. Let's say you like to query current records in your found set as JSON, how would you do this?

First you need the list of the primary keys and we like to use a While() for this. For older FileMaker versions, you could use FM.Loop instead. The loop goes over found set and just queries primary key fields for all records in found set:

While ( [ liste = ""; i = 0 ] ; i < Get(FoundCount) ; [ i = i + 1; liste = GetNthRecord ( FileMaker Ideas::PrimaryKey ; i ) & "¶" & liste ] ; liste )

We could store this in $Keys and then continue with building the request, which needs to include the layout to use and the query, which looks for all the records by ID. 

Set Variable [ $Request ; Value: JSONSetElement ( "{}"

    [ "layouts" ; "FileMaker Ideas" ; JSONString ] ;

    [ "query" ; "[{ \"PrimaryKey\":\"==" & Substitute($Keys; ¶; "\"},¶{ \"PrimaryKey\":\"==") & "\" }]" ; JSONArray ] 

)

Now we can just run this via Data API:

Execute FileMaker Data API [ Select ; Target: $$JSON ; $Request ] 

Now you can query the result from the response:

Set Variable [ $$Result ; Value: JSONFormatElements ( JSONGetElement ( $$JSON ; "response.data" ) ) ] 

And if you use MBS FileMaker Plugin, get some color to show JSON in a field:

Set Variable [ $$ResultColored ; Value: MBS("JSON.Colorize"; $$Result) ] 

Please try and let me know if you can use this in your development in FileMaker.


Xojo Tips and Tricks

We got a few tips and tricks collected for you in the last week.

1. App.Constructor

If you need code to run really first, you may go with the constructor of the Application object. This constructor runs before the Opening event, so it is your chance to do very early initialization before all other events run. But using Constructor can be tricky since you need to call the constructor on the super class and match the signature, which is not always easy to know. Let us show you how the constructors would like

Console and Desktop targets:

Sub Constructor()
System.DebugLog CurrentMethodName
End Sub

Web target:

Sub Constructor()
System.DebugLog CurrentMethodName

// Calling the overridden superclass constructor.
Super.Constructor
End Sub

iOS target:

Sub Constructor(launchOptions As ptr)
System.DebugLog CurrentMethodName

// Calling the overridden superclass constructor.
Super.Constructor launchOptions
End Sub

For some projects we use constructor to put in some logging or plugin based exception catching very early to catch issues before App.Open event runs. See NSExceptionHandlerMBS and GlobalExceptionHandlerMBS classes. (more)

Check Variables for Let

As you may know we have a variable check for FileMaker script workspace for macOS in MBS FileMaker Plugin. This works fine for most scripts, but you may need to know a few pitfalls. Since the plugin reads what is in the script workspace window and FileMaker truncates long lines, it will not catch a variable mistyped in a very long line. When we read a calculation like this one:

 

Let([

// define some variables

$varDefined = 1; $secondVarDefined = 2]; $varDefined) 

 

The plugin sees it as

 

Let([ // define some variables $varDefined = 1; $secondVarDefined = 2]; $varDefined) 

 

We don't get line breaks, so we have no idea where the comment ends and thus we can't find mistyped variable there.

 

There has been a problem that not scanning Let() for variable definitions, we now allow you to add a comment in front of the Let() or custom function call to define the variables: Start with a // comment and add they keywords @variable, @parameter or @constant (or shorter @var, @param or @const), then add a new line and continue with the calculation.

Six months until MBS Xojo Developer Conference

Just six months left until we start our MBS Xojo Developer Conference in Andernach, Germany. We know it is still early, but we already got a few speaker proposals and already the first dozen registrations from six different countries: 🇩🇪, 🇳🇱, 🇬🇧, 🇺🇸, 🇫🇷 and 🇨🇭.

Outside image of hotel at night.

Please join us 25th and 26th April 2024 in Andernach, Germany for a great Xojo developer conference. You may consider to arrive 24th April to join the evening reception in the hotel. Or even arrive earlier to join our Xojo training day. And if you come from far away, how about staying longer and do a bit of sight seeing with the group on Tuesday?


Moving to new JSONMBS class

If you used our older JSONMBS class and now move to 23.5 version of MBS Xojo Plugins, you may notice a few changes. The new class is better in many ways, like interface compatible to JSONItem class, adds new Query, Search and Replace methods as well as handling errors better.

We got new kType* constants for new node types. Error, True, False and Number types are gone and we got new things like Boolean, ByteString, Int64, Single, Double and UInt64. The byte string is for handling MemoryBlocks in JSON, which can encoded as Hex, Base64 or Base64URL as needed.

We now raise exceptions for all bad operations. So checking handle for 0 and checking ParseError property is gone. You can inspect the exception for it's message property to see an error message.

We preserve numbers in exact representation. If you store 1.2345 as currency into JSON with our plugin, it will stay 1.2345 and not convert internally to a double and get output as 1.2344999999999999307. Our IsNumber function handles this correctly. So if a floating point number is stored internally as string, you may see kTypeString for it, but IsNumber returns true as it's a string we use to hold a number and output it as number. We also got functions like IsInt64, IsUInt64, IsInt32 and IsUInt32 which check for IsNumber and the range. (more)

List dialog with checkboxes

As you may know, you can show a list dialog with MBS FileMaker Plugin by using our ListDialog functions. For next version 13.5 we add new functions for having checkboxes in the list.

Screenshot from macOS:

The list dialog can now operate in multiple modes:

Using JSONPath in FileMaker

For the upcoming MBS FileMaker Plugin 13.5 release, we add three new functions:

JSONPath queries can be used in FileMaker to work with JSON data, which is increasingly common in modern application development. FileMaker allows you to work with JSON data using the JSON functions introduced in FileMaker 16 and later versions as well as with JSON functions in our plugin. JSONPath queries can be useful in the following ways:

Checking out Search function in JSONMBS with Xojo

JMESPath (pronounced "jay-mess-path") is a query language and a specification for searching and extracting data from JSON documents. It provides a way to perform complex queries and transformations on JSON data, making it easier to work with structured data within JSON objects. JMESPath is similar in concept to other query languages like SQL for databases or XPath for XML documents, but it's specifically designed for JSON.

We add JMESPath to our MBS Xojo Util Plugin for the upcoming version 23.5 with the Search()) function in JSONMBS class. You may use this function to find things and then also check Replace() to replace values you selected with an expression.

Playing with JSON Query in Xojo

Let's play a bit with our new JSONMBS class in Xojo and the query function there to run a few queries.

You may want to learn a bit about JSONPath and especially the implementation we use: JsonConsJsonPath.
Let me give you a bit of a summary about JSONPath here:

JSONPath is a query language used for extracting data from JSON documents. It is similar in concept to XPath, which is used for querying XML documents. JSONPath allows you to navigate and filter through the elements and values in a JSON structure to retrieve specific data or perform operations on it.

Here's an overview of the basic syntax and features of JSONPath:

19 years of FileMaker versions supported

Did you know the MBS FileMaker Plugin can run on all FileMaker versions from 7 to 20.2.1?

As of today the current 32-bit Windows version can load in ancient FileMaker Pro 7. We don't expect clients to use that, but from time to time, a client asks about an older FileMaker version. We highly recommend to upgrade to a more recent version.

As of today, we have about 21% of users with FileMaker 20.x, about 72% on some 19.x version and just about 6% on older versions.

For macOS we support currently macOS 10.13 and newer in FileMaker 14 and newer. If you need plugins folder older macOS versions or 32-bit FileMaker Pro, please let us know.
For Windows we support currently Windows 8 and newer. Some features require Windows 10 or newer of course. Please contact us if you need a MBS Plugin version to run on Windows 7 or Windows Server 2012 for some reason.

We also support the Claris Pro/Server line of products in case you use them.

And of course we work hard to get our plugin ready for the future. We usually test with future FileMaker versions in beta testing, so we are ready for any change long before the release.

Let us know if you have questions.

Time to switch to MBS Xojo SQL Plugin

Anyone using Oracle or Microsoft SQL Server out there with Xojo?

OracleDatabase and MSSQLServerDatabase class were deprecated in Xojo 2023r2 and you are recommended to use ODBCDatabase class instead.

If you need native access to Oracle, Microsoft SQL Server and other databases, your best choice is to use our MBS Xojo SQL Plugin.

We provide direct access to CubeSQL, Centura SQLBase, DB2, DuckDB, Firebird, Informix, InterBase, MariaDB, Microsoft Access, Microsoft SQL Server, MySQL, ODBC, Oracle Database Server, PostgreSQL, SQL Anywhere, SQLite, SQLCipher and Sybase. And of course we got MongoDB classes, too.

Please try it and let us know if you have questions.

How long do you wait for Insert From URL to finish?

Did you know you can run CURL commands in background with MBS FileMaker Plugin?

 

Let's start with a simple Insert From URL script like the following one. $url has the URL to query and $json the data to send to whatever web API you like to query. The headers include authentication and content types. Nothing special. The query runs and stores result in $$result and a log into $$debug. Here is the script:

 

Set Variable [ $options ; Value: "-X POST --header \"Authorization: Basic <<API KEY>>\" --header \"Content-Type: application/json\" --header \"Accept: application/json\" --trace $$debug --data @$json " ] 

Insert from URL [ Select ; With dialog: Off ; Target: $$result ; $url ; cURL options: $options ; Do not automatically encode URL ] 

 

After this is run through, you may inspect Get(LastError) as well as $$result and $$debug. And depending on how long your query runs, the FileMaker script may pause. If the server isn't answering, it may wait 90 seconds for a timeout (unless changed). Especially if you upload images over slow connections, the user may have to wait.

More Menubar options in macOS Sonoma

Your desktop app made in Xojo can take advantage of new menu features in macOS Sonoma. You can use section headers as well as color palettes. And you may use our SystemInformationMBS.isSonoma function a lot to check if your application runs on macOS Sonoma. Then you can dynamically use the new features, if you have macOS 14.0 or higher.

Let's start with the Opening event of the application or a window, where we edit the menu bar. We Query menu item (NSMenuItemMBS) representing the EditMenu and start by adding a separator item there. Then we create a section header. To avoid the objects being destroyed too early, we store the references in properties.

For the color palette, we first collect a few NSColorMBS objects in an array as well as the matching titles. Then we create a palette menu for them. To later catch the event for a selection, we connect the PaletteSelectionChange event and add the new menu as a submenu to a new menu item.

See you at Claris Engage 2024

Claris comes back with an in-person conference and well, they are a bit cautious after the pandemic. Will people return in numbers like before?

For 2024 Claris decided to keep the ball low and pick an Apple owned facility to run the conference. Sure, that saves a lot of money, which previously went to Marriott, but it separates the conference a lot from the hotel. Attendees are asked to pick a hotel in the The Domain area, a development in north Austin with a lot of shops and restaurants. It should be easy for us to meet there at various hotel bars or restaurants after the show.

The Claris Engage conference will take place one day in the Apple Campus (6900 West Parmer Lane) for training and keynote. After the keynote, we'll have a party (reception?) with food and drinks. Plenty of time to welcome old friends and talk about the keynote content. The other two days are on a different Apple Campus (5505 Parmer Lane). All the sessions will be there with lunches and refreshment breaks. Since there is no bus shuttle, be sure to organize car pools with your fellow developers.

Since the conference is going to be smaller, we attend just with one person and that is me. Not sure if we get a booth this time. As the conference is basically only 2 days plus keynote on the evening before, we expect quite a few Europeans to skip the conference this year. They would be traveling longer, then they'd be at the conference! And of course Europeans may prefer to just got to EngageU in Europe (12th - 14th of November 2023 in Antwerp, Belgium). February in Austin may not encourage attendees to stay longer and make it a little vacation.

The conference ticket is $1399 USD plus optional a $449 USD training day ticket. The early bird offer sold out the first day, so 200 people got their ticket already. If you stay at home, there is a $99 option to get just the recordings. No idea whether recordings may eventually go to Claris' channel on YouTube like the years before.

Some decisions are hard to understand. We hoped for the Nashville conference plans to be executed for 2024 (after being cancelled in 2020), but that didn't happen. I really hope for a bigger conference in 2025, maybe in California, if Apple has bigger facilities there? The yearly conference is the show case of the platform. It shows how many people are interested in the products, it brings together the developers to share knowledge, it lets Claris show off their new stuff and it creates high level content to show and publish later.

See you in Antwerp and in Austin!
