About Delphi Pascal

function DigitSum(AValue: Int64): Integer;
begin
  if AValue mod 10 = AValue then
    Result := AValue
  else
    Result := (AValue mod 10) + DigitSum(AValue div 10)
end;

Delphi is an Object Pascal based programming language for desktop, mobile, web, and console software development. Delphi was the code name for a yet unnamed product during its initial development prior to its debut in 1995.

Delphi was originally developed by Borland, lead by Anders Heilsberg as a RAD tool for Windows as the successor of Turbo Pascal. Delphi added full object-orientation to the existing language, and since then the language has grown and supports many other modern language features, including:

  • Generics
  • Anonymous Methods (Closures)
  • Dynamic Constructs (Attributes)
  • Abstract Methods
  • Inbuilt string types
  • Native COM support
  • RTTI

Like its predecessor Turbo Pascal, at the core of Delphi is a native code compiler. Turbo Pascal provided an ideal balance between the speed of programming and the speed of the resulting programs, clarity of syntax and power of expression, these tenets remain true today in Delphi. More recent versions of Delphi are able to compile native code for many different platforms:

  • Windows (x86 and x64)
  • OS X (32 bit only)
  • iOS (32 and 64 bit)
  • Android
  • Linux (64 bit only)

In 2006, Borland’s developer tools section were transferred from Borland to a wholly owned subsidiary known as CodeGear, which was sold to Embarcadero Technologies in 2008. In 2015, Embarcadero was purchased by Idera, but the Embarcadero mark was retained for the developer tools division.

A tremendous learning opportunity to explore the depth of your own knowledge

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.

Relaxed. Encouraging. Supportive.

I began programming with Turbo Pascal in 1987 and later I discover Delphi. I like to help others and Exercism is the right place.

I have been using Delphi professionally since 1996. Exercism is my first real push into Open Source and I'm happy to have this opportunity to teach and share the virtues of Delphi with others.
Fun. Challenging. Interesting

I have been using Delphi professionally since 1996. At my day job I develop software used in the control of various types of test machines used by the auto industry. Exercism is my first real push into Open Source and I'm happy to have this opportunity to teach and share the virtues of Delphi with others.

Get started with the Delphi Pascal track. As with everything on Exercism, it's 100% free!
