By now you probably know about GraphQL, or at least you might have read or heard that name somewhere. Wikipedia says that “GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data”. If that doesn’t say much to you, or if you have read about GraphQL before but didn’t understand very well what it is, then this article is for you. Its purpose is to try – again – to explain what GraphQL is, its advantages and disadvantages, from the perspective of a Delphi (and also TMS XData) developer.

In November 2019, TMS Days 2019 took place in both Düsseldorf, Germany and Wevelgem, Belgium. It was the biggest TMS event ever, with three full days in two different cities, and team members from nine different countries around the world.

It was a face-to-face event and even before the event started many people from all over the world approached us asking if they could watch the content online since they could not travel to attend the event in person.

Inline variables declaration is a feature introduced in Delphi Rio 10.3. What is it?

In short, it is the possibility to declare a variable in any line of your code. That is, you can declare a variable this way, within the begin..end block:

procedure Test;
begin
var I: Integer;

ShowMessage (I.ToString);
end;

A lot of people already understood how this feature works, but did not understand why it is interesting. In this article, I will show you this new feature with a focus on the advantages it brings.

Embarcadero has just released a new Delphi Rio version (which means also Rad Studio and C++ Builder): version 10.3.2. It’s a minor update – meaning product codename is still “Rio”, and it’s binary (DCU) compatible with previous 10.3.1 version.

Why then, an article about a minor update? Usually minor updates contain just bug fixes and small improvements, however it’s not the case of this one.

It’s also worth mentioning that Embarcadero has recently published the updated Rad Studio roadmap – May 2019 which lists the probable new improvements in upcoming major versions.
