https://www.youtube.com/watch?v=vYEKEIpM2zo&t=1sD is a systems programming language with C-like syntax and static typing. It combines efficiency, control, and modeling power with safety and programmer productivity.
Producing correct programs has notoriously been expensive in systems programming. Depending on the language used, programmers face a combination of labor and time intensive issues including struggling with language peculiarities, writing boilerplate code, code generation with difficulty or with external tools, manual resource management, and having to abide by long lists of coding guidelines. Correct programs further require prototyping sometimes with auxiliary languages and unit testing with external frameworks. It is not uncommon that readability and maintainability are sacrificed in the process.
D has minimal historical baggage, outstanding compile-time capabilities, useful exceptions, compiler-guaranteed memory safety, internal unit testing, and optional garbage collector as parts of an extensive feature set. Its features spanning from the lowest to the highest levels of programming paradigms generally obviate auxiliary languages in production.
This talk will give a general introduction of D, focusing mainly on its compile-time features like reflection, templates, code generation, conditional compilation, and user defined attributes; and present D as a time-saving software engineering tool suited for business requirements.
Because C++ is such a powerful language and because C++Now attendees are master users of it, it will be hard to argue for a single feature of D that would make one prefer D over C++. We know that one can achieve almost any programming task in C++, D, or most other languages. The killer feature of D is that the whole package it delivers makes it easier to achieve those tasks. That is the competitive advantage that it brings to D users.
