D2 later added numerous other language features, such as closures, purity, and support for the functional and concurrent programming paradigms. * 입력한 날짜의 D-Day를 계산합니다. Visual Studio integration is provided by VisualD. D takes a permissive but realistic approach to interoperation with C++ code.[30]. Ignored for parameters with no references. Walter Bright started working on a new language in 1999. * 년도 입력은 0 ~ 9999 입니다. This is a regular function that calculates the factorial of a number: Here, the use of static if, D's compile-time conditional construct, is demonstrated to construct a template that performs the same calculation using code that is similar to that of the function above: In the following two examples, the template and function defined above are used to compute factorials. D was first released in December 2001[1] and reached version 1.0 in January 2007. [45], As of GCC 9, GDC (short for GNU D Compiler, or GCC D Compiler), a D language frontend based on DMD open source frontend was merged into GCC.[46]. Metaprogramming is supported by a combination of templates, compile-time function execution, tuples, and string mixins. Andrei Alexandrescu joined the design and development effort in 2007. 이 문서는 2020년 4월 17일 (금) 22:28에 마지막으로 편집되었습니다. As such it is not source compatible (and doesn't aim to be) with C and C++ source code in general (some simpler code bases from these languages might by luck work with D, or require some porting). D2 also solved standard library problems by separating the runtime from the standard library. D also includes dynamic arrays and associative arrays by default in the language. 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. D, also known as Dlang, is a multi-paradigm system programming language created by Walter Bright at Digital Mars and released in 2001. [41] In 2014 the compiler front-end was re-licensed as open source under the Boost Software License. Editors and integrated development environments (IDEs) supporting D include Eclipse, Microsoft Visual Studio, SlickEdit, Emacs, vim, SciTE, Smultron, TextMate, MonoDevelop, Zeus,[56] and Geany among others.[57]. Dynamic arrays (though slices of static arrays work) and associative arrays, Static module constructors or destructors. [38], In December 2011, Andrei Alexandrescu announced that D1, the first version of the language, would be discontinued on December 31, 2012. D does not support multiple inheritance; instead, it uses Java-style interfaces, which are comparable to C++'s pure abstract classes, and mixins, which separates common functionality from the inheritance hierarchy. C++ multiple inheritance was replaced by Java-style single inheritance with interfaces and mixins. 일부 핵심 C++ 기능들을 다시 설계하였으며 자바, 파이썬, 루비, C#, 에펠과 같은 다른 언어들의 특징들을 공유하기도 한다. [35], In June 2007, the first version of D2 was released. For example, there are bi-directional bindings for languages like Python,[27] Lua[28][29] and other languages, often using compile-time code generation and compile-time type reflection methods. For other programming languages named D, see, Multi-paradigm system programming language, Function Parameter Lifetime Annotations within @safe code, Features available in the Better C subset, Features unavailable in the Better C subset, // hypothetical module which contains a function that parses Foo source code, // must be immutable to allow access from inside a pure function, // The body of the foreach loop is executed in parallel for each i. Whatever the memory is deallocated also depends on implementation and class-vs-struct differences. [4][42][43][44] On June 21, 2017, the D Language was accepted for inclusion in GCC. This page was last edited on 21 December 2020, at 21:42. The first public Tango announcement came within days of D 1.0's release. Ordinary functions may be used in constant, compile-time expressions provided they meet certain criteria: The std.string.format function performs printf-like data formatting (also at compile-time, through CTFE), and the "msg" pragma displays the result at compile time: String mixins, combined with compile-time function execution, allow generating D code using string operations at compile time. The release of Andrei Alexandrescu's book The D Programming Language on June 12, 2010, marked the stabilization of D2, which today is commonly referred to as just "D". 2020.12.23(수) 점검 후 ~ 2021.1.13(수) 점검 전 ! Google allows users to search the Web for images, news, products, video, and other content. [16], In function, static arrays (of known size) are allocated on stack. For D code marked as extern(C++), the following features are specified: C++ namespaces are used via the syntax extern(C++, namespace) where namespace is the name of the C++ namespace. Symbols (functions, variables, classes) can be declared in any order - forward declarations are not required. A DustMite is a powerful tool for minimize D source code, useful when finding compiler or tests issues. However this can be changed for classes, for example using standard library template std.typecons.scoped, or by using new for structs and assigning to pointer instead to value-based variable. Garbage collection can be controlled: programmers may add and exclude memory ranges from being observed by the collector, can disable and enable the collector and force either a generational or full collection cycle. For example GDC compiler allow to link C, C++, and other supported language codes to be intermixed. 모든 플랫폼에서 무료바둑게임,온라인바둑,바둑어플,바둑강좌,기보감상,바둑생중계,바둑동호회,프로기사강좌,바둑비타민,oro … 2001년 공개되었다. Idiomatic D code is commonly as fast as equivalent C++ code, while also being shorter. This usually restricts use to primitive types, pointers, some forms of arrays, unions, structs, and only some types of function pointers. C++의 리엔지니어링으로 기원하였으나 D는 해당 언어와는 별개의 언어이다. [14] The manual gives many examples of how to implement different highly optimized memory management schemes for when garbage collection is inadequate in a program. This is what majority of programs and libraries written in D use. The returned pointer can be used (recast) into a (typed) dynamic array, by means of a slice (however resizing array, including appending must be avoided; and for obvious reasons they must not be returned from the function). 1. 일부 핵심 C++ 기능들을 다시 설계하였으며 자바, 파이썬, 루비, C#, 에펠과 같은 다른 언어들의 특징들을 공유하기도 한다. Memory is usually managed with garbage collection, but specific objects may be finalized immediately when they go out of scope. A string in D is an array of characters, represented by immutable(char)[]. This can be used to parse domain-specific languages to D code, which will be compiled as part of the program: D supports functional programming features such as function literals, closures, recursively-immutable objects and the use of higher-order functions. Ignored for parameters with no references, Parameter may be returned or copied to the first parameter, but otherwise does not escape from the function. yes24는 대한민국 1위 인터넷 온라인 서점 입니다. It iterates over the lines of a text file named words.txt, which contains a different word on each line, and prints all the words that are anagrams of other words. The types of constants need not be specified explicitly as the compiler infers their types from the right-hand sides of assignments: This is an example of compile time function execution. Select a coupon to book with discounted mileage. Using above compilers and toolchains, it is possible to compile D programs to target many different architectures, including x86, amd64, AArch64, PowerPC, MIPS64, DEC Alpha, Motorola m68k, Sparc, s390, WebAssembly. Likewise, to implement a closure, the compiler places enclosed local variables on the heap only if necessary (for example, if a closure is returned by another function, and exits that function's scope). Most current D implementations compile directly into machine code for efficient execution. Alternatively, the above function compositions can be expressed using Uniform Function Call Syntax (UFCS) for more natural left-to-right reading: Parallel programming concepts are implemented in the library, and don't require extra support from the compiler. D code (functions) can also be marked as using C, C++, Pascal ABIs, and thus be passed to the libraries written in these languages as callbacks. The same module also supports taskPool that can be used for dynamic creation of parallel tasks, as well map-filter-reduce and fold style operations on ranges (and arrays), which is useful when combined with functional operations: This code uses fact that the std.algorithm.map doesn't actually return an array, but a lazily evaluate range, this way the actual elements of the map are computed by each worker task in parallel automatically.

Coupon discounts only … Many aspects of classes (and structs) can be introspected automatically at compile time (a form of reflection using type traits) and at run time (RTII / TypeInfo), to facilitate generic code or automatic code generation (usually using compile-time techniques). On the other hand, D's declaration, statement and expression syntax closely matches that of C++.
