D

From Wikipedia:D (programming language):

• it is an object-oriented, imperative, multi-paradigm system programming language;
• it is predominantly influenced by C++, but it is not a variant of it;
• it also has been influenced by concepts used in C#, Eiffel and Java.

Installation

To program in D you will need two things—a D compiler and a library. The easiest way to get started fast is to install dlang-dmd package group. It will provide the official compiler dmd, the standard library libphobos, and dtools—a collection of small development tools.

Testing the installation

To make sure that everything is installed and set up correctly, a simple "Hello World" program should suffice.

hello.d

import std.stdio;

void main() {
   string yourName = "archer";
   writefln("Hello %s!", yourName);
}

And run:

$ dmd hello.d

in the same directory as the file. You should then be able to execute the program with:

$ ./hello

You can also execute

$ dmd -run hello.d

which will simply compile and run without leaving any object files in the directory.

Considerations

There are however possible choices regarding the compiler you choose. The reference implementation is dmd, but gcc-d (D frontend for GCC) and ldc (LLVM D Compiler) are also available.

As of April 2017 dmd's backend is now FOSS (Boost-licensed). All compilers share the same front-end code and thus have almost identical support for language features (assuming same front-end version).

Useful libraries and bindings

• DDT - Eclipse plugin for project and code management in D
• Mono-D - MonoDevelop addin for programming in D
• QtD - Qt bindings for D
• GtkD - An object oriented GTK wrapper for D
• Derelict - Bindings for multimedia libraries, focused toward game development
• Deimos - A project that houses a lot of bindings to different C libraries
