With class helpers new functionality can be introduced to core RTL and VCL classes without changing the original source code of the RTL or VCL. Get to the bottom of bugs faster with integrated cross-platform native debugging. Third-party libraries typically need updates from the vendor but, if source code is supplied, recompilation with the newer version may be sufficient. Although each new release of Delphi attempts to keep as much backwards compatibility as possible to allow existing code reuse, new features, new libraries, and improvements sometimes make newer releases less than 100% backwards compatible. Delphi can also generate standard DLLs, ActiveX DLLs, COM automation servers and Windows services. It supports native cross compilation and rapid development of application (RAD).

The Delphi products all ship with a run-time library (RTL) and a Visual Component Library (VCL), including most of its source code. Turbo Pascal and its descendants, including Delphi, support access to hardware and low-level programming, with the facility to incorporate code written in assembly language and other languages. Be sure to watch the webinar! Delphi is both an object oriented programming language (OOP) and an Integrated Development Environment (IDE). The 64-bit Linux compiler no longer uses ARC, it instead uses the default manual managed, which is the same as in the Windows compiler.This makes porting code from Windows or OSX to linux much easier. Want to Write More Code – Delphi requires less code to accomplish the same task.If you want to write more code, don’t use Delphi. Allen appeared, saying that it should be understood that these generics were only the first step towards "LINQ-like functionality" and then language-level parallel programming features. 17 Comments on Hidden features in the Delphi Object Pascal language A list of hidden features in Delphi Object Pascal that are great, obscure, best avoided or remarkable. With the help of seven practical projects, this book will guide you through the best practices, Delphi Run-Time Library (RTL) resources, and design patterns.

And check out the new features of the Delphi language here: Object Pascal Variable Scope: now you see me, now you don't. As a reminder a short recapitulation of what that stands for : Objects are a grouping of data and methods (functions) working on that data. Ordinal and Enumerated Data TypesExtend Delphi's built-in types by constructing your own types. It means, beyond the OOP with the Generic Types, Anonymous Methods, extended RTTI, and the ability to create highly dynamic code. Arrays in Object PascalUnderstanding and using array data types in Delphi. [32], RAD Studio is both the formal name for the IDE and a product suite that contains both Delphi and C++Builder. ... Delphi, Ada, C++, Python, Lisp, and Oberon. Delphi's object orientation features only class- and interface-based polymorphism. Delphi is known for its fast compilation speed, native code, and developer productivity. Delphi added full object-oriented programming to the existing language, and the language has grown to support generics, anonymous methods, closures, and native Component Object Model (COM) support. The Enterprise and Architect editions of RAD Studio currently include Aqua Data Studio and Ext JS.[33]. Objects are actually references to the objects (as in Java), which Delphi implicitly de-references, so there is usually no need to manually allocate memory for pointers to objects or use similar techniques that some other languages need. The compiler is optimizing and single pass.
