Apache Groovy events you shouldn’t miss! GR8Conf is a series of d programming language gui founded to spread the word worldwide. The 2018 GR8Conf Europe is celebrating its 10th year, and it’s expected to be a blast.
It has its own organization and its own crew. It is founded to spread the word about the fantastic Groovy technologies and community. Enter the characters you see below Sorry, we just need to make sure you’re not a robot. D’s design goals attempt to combine the performance and safety of compiled languages with the expressive power of modern dynamic languages. D has, however, been constrained in its design by the rule that any code that is legal in both C and D should behave in the same way. D has built-in support for documentation comments, allowing automatic documentation generation. Imperative programming in D is almost identical to that in C.

Functions, data, statements, declarations and expressions work just as they do in C, and the C runtime library may be accessed directly. Object-oriented programming in D is based on a single inheritance hierarchy, with all classes derived from class Object. Metaprogramming is supported by a combination of templates, compile time function execution, tuples, and string mixins. The following examples demonstrate some of D’s compile-time features. In the following two examples, the template and function defined above are used to compute factorials. This is an example of compile time function execution. String mixins, combined with compile-time function execution, allow generating D code using string operations at compile time.
D supports functional programming features such as function literals, closures, recursively-immutable objects and the use of higher-order functions. There are two built-in types for function literals, function, which is simply a pointer to a stack-allocated function, and delegate, which also includes a pointer to the surrounding environment. Type inference may be used with an anonymous function, in which case the compiler creates a delegate unless it can prove that an environment pointer is not necessary. Other functional features such as currying and common higher-order functions such as map, filter, and reduce are available through the standard library modules std. Memory is usually managed with garbage collection, but specific objects may be finalized immediately when they go out of scope.
