What is a .D file?
A .D file is a type of computer file known as a D Source Code File. It contains source code, which is a set of instructions written by a programmer. This particular source code is written in the D programming language. The D programming language is similar to C++, but it also takes some ideas from other programming languages like C#, Java, and Eiffel.
To open and look at the contents of a .D file, you can use a simple text editor, which is a program that lets you read and edit plain text. Examples of text editors include programs that come with your computer or ones you can download, like Notepad on Windows or TextEdit on Mac. There are also more advanced text editors specifically designed for coding, such as MacroMates TextMate.
However, just looking at or editing the .D file isn't enough to make the program run on your computer. For that, you need a special program called a D compiler. A compiler takes the source code written in a programming language and turns it into an executable program, which is a file that your computer can run.
Some programs that can open and work with .D files include Code::Blocks, which is an environment where you can write, edit, and compile your D code all in one place. Since .D files are plain text, you can also use any basic text editor to open them, but you won't be able to compile the code without a D compiler.
Additionally, .D files are often used with GNU Make. GNU Make is a tool that helps programmers automatically build and manage the files in their projects, especially when those projects have lots of files that need to be compiled in a specific order.
In summary, .D files contain code for programs written in the D language. You can view and edit these files with text editors or specialized programs like Code::Blocks, but to turn the code into a running program, you need a D compiler.
