The D Programming Language, Version 1.0

Posted by kdawson on from the coming-of-age dept.

penguinblotter writes in a journal article: "Soon, Walter Bright is scheduled to release version 1.0 of the D Programming Language. D is a systems programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python. Special attention is given to the needs of quality assurance, documentation, management, portability and reliability. D has appeared on Slashdot a few times before, and Walter has continued to add more and more features. Most Slashdot community comments in these articles have been offered on feature X or spec Y without reading through the extensive D newsgroup archives. It has been here over the past seven years where extremely gifted and experienced programmers hashed out discussions and arrived at excellent implementations of all the ideas discussed." Read on for the rest of penguinblotter's writeup.
For those with a C/C++ background, D offers:
  • native code speed
  • extremely fast compilation times
  • garbage collection (although you can manage your own memory if you want)
  • OOP - by reference only, easy initialization, always virtual
  • cleaner template metaprogramming syntax, more powerful templates, as well
  • built-in dynamic and associative arrays, array slicing
  • versioning (no preprocessor madness)
  • link-compatibility with C
  • nested functions
  • class delegates / function pointers
  • module system
For those with a C#/Java background (a shorter list, but one with big wins):
  • similar syntax
  • No virtual machine or interpreter
  • built-in unit testing and design-by-contract
These two comparison sheets can go into more depth on how D stacks up against other languages.

From D's creator:
For me, it's hard to pinpoint any particular feature or two. It's the combination of features that makes the cake, not the sugar, flour or baking powder. So,
  1. My programs come together faster and have fewer bugs.
  2. Once written, the programs are easier to modify.
  3. I can do (1) and (2) without giving up performance.
Get your compilers and start hacking D!

  • GDC (GCC front-end)

      So - that only leaves you the letters H, I, N, O, P (sic!), U, V, W, Y and Z

      I hope someone creates an "O" language. That way, interface bindings for it could be called "O-interfaces", or "O-faces" for short. So when you create a nifty library for the language, publishing it could be known as "showing the world your O-face".

    After working so hard to get from C to C++, I don't see why I would settle for D. My next programming language is going to be B- or better.

    I'll stick to languages that have at least a professional following, in use by real software engineers (that is, engineers who can legally call themselves engineers), not the run of the mill code monkeys. I'm dying to know... do you mean Fortran or Lisp?

    I just can't see why I'd want to switch to a language that has no IDE support and is evolutionary to C# or C++. I hardly have to look at documentation for APIs anymore because I can just use Visual Studio's autocompletion to figure things out.

    I mean, like, I try to write this program, and like, the language does ONLY what I tell it to, not what I really want. That really sucks.
