“It seems to me that most of the ‘new’ programming languagesfall into one of two categories: Those from academia with radicalnew paradigms and those from large corporations with a focus on RADand the web. Maybe it’s time for a new language born out ofpractical experience implementing compilers.” -- Michael
“Great, just what I need.. another D in programming.” -- Segfault
D is a systems programming language.Its focus is on combining the power and high performance of C and C++ withthe programmer productivity of modern languages like Ruby and Python.Special attention is given to the needs of quality assurance, documentation,management, portability and reliability. The D language is statically typed and compiles directly to machine code.It’s multiparadigm, supporting many programming styles: imperative, object oriented, and metaprogramming. It’s a member of the C syntax family, and its appearance is very similar to that of C++.Here’s a quick list offeatures. It is not governed by a corporate agenda or any overarching theory ofprogramming. The needs and contributions of theD programming community form the direction itgoes. |
There are two versions of the language:
There are currently four implementations:
A large and growing collection of D source code and projectsare atdsource.More links to innumerable D wikis, libraries, tools, media articles,etc. are atdlinks.
This document is available as apdf,as well as inJapaneseandPortugesetranslations.A German bookProgramming in D: Introduction to the new Programming Languageis available, as well asa Japanese bookD Language Perfect Guide,and a Turkish bookD Programlama Dili Dersleri.
This is an example D program illustrating some of the capabilities:
#!/usr/bin/dmd -run/* sh style script syntax is supported *//* Hello World in D To compile: dmd hello.d or to optimize: dmd -O -inline -release hello.d*/import std.stdio;void main(string[] args){ writeln("Hello World, Reloaded");// auto type inference and built-in foreachforeach (argc, argv; args) {// Object Oriented Programmingauto cl =new CmdLin(argc, argv);// Improved typesafe printf writeln(cl.argnum, cl.suffix," arg: ", cl.argv);// Automatic or explicit memory managementdelete cl; }// Nested structs and classesstruct specs {// all members automatically initialized size_t count, allocated; }// Nested functions can refer to outer// variables like args specs argspecs() { specs* s =new specs;// no need for '->' s.count = args.length;// get length of array with .length s.allocated =typeof(args).sizeof;// built-in native type propertiesforeach (argv; args) s.allocated += argv.length *typeof(argv[0]).sizeof;return *s; }// built-in string and common string operations writefln("argc = %d, " ~"allocated = %d",argspecs().count, argspecs().allocated);}class CmdLin{private size_t _argc;private string _argv;public:this(size_t argc, string argv)// constructor { _argc = argc; _argv = argv; } size_t argnum() {return _argc + 1; } string argv() {return _argv; } string suffix() { string suffix ="th";switch (_argc) {case 0: suffix ="st";break;case 1: suffix ="nd";break;case 2: suffix ="rd";break;default:break; }return suffix; }}Notice: We welcome feedback about the D compiler or language, but please be explicit aboutany claims to intellectual property rights with a copyright or patent notice if you have such foryour contributions. We want D to remain open and free to use, and do not wish to be caught bysomeone posting a patch to the compiler, and then later claim compensation for that work.
