Most notably, the Object Pascal/Delphi compiler is written in mostly C with a smattering of C++, the editor kernel (sans display rendering) and debugger engine (process control/symbol table management) were written in C++. All of which I’ve worked on throughout my 24+ years on that team.
The 16bit compiler was written in pure assembler. The current compiler is written in C. It was derived from an Amiga 68000 Turbo Pascal compatible compiler. It’s never been written in Object Pascal.
That being said, there was an effort several years ago to completely rework/re-architect the compiler. That was done in OP. It just barely got to the “hello world” stage before it was set aside.
Slow pages lose users: research from Bing and Google indicates that delays as small as half a second can impact business metrics. To build fast sites, developers need powerful tools to analyze the …
Nick Hodges did the technical review, and since Nick’s book are great I have high hopes (:

Full Description
Dive into the world of MVVM, learn how to build modern Windows applications, and prepare for cross-platform development. This book introduces you to the right mindset and demonstrates suitable methodologies that allow for quick understanding of the MVVM paradigm. MVVM in Delphi shows you how to use a quick and efficient MVVM framework that allows for scalability, is of manageable complexity, and provides strong efficiency.
One of the biggest challenges developers face is how to convert legacy and monolithic Delphi applications to the MVVM architecture. This book takes you on a step-by-step journey and teaches you how to adapt an application to fit into the MVVM design.
What you’ll learn
Gain the fundamentals of MVVM
Visualize MVVM as a design philosophy
Create easy-to-use frameworks for building your own MVVM applications
Develop a methodology for converting legacy applications to the MVVM pattern
Architect cross-platform and multi-lingual applications using the MVVM pattern
Who this book is for
Delphi developers with a good knowledge of Delphi or programming experience in a different language. In addition, this book is attractive to Delphi developers who want to modernize existing applications based on the MVVM design.
