d

I've posted this on the D newsgroup some months ago, but for some reason, the answer never really convinced me, so I thought I'd ask it here. The grammar of D is apparently context-free . The grammar of C++, however, isn't (even without macros). ( Please read this carefully! ) Now granted, I know nothing (officially) about compilers, lexers, and parsers. All I know is from what I've learned on the web. And here is what (I believe) I have understood regarding context, in not-so-technical lingo: The grammar of a language is context-free if and only if you can always understand the meaning

Is anyone out there using D for real world applications? If so, what are you using it for? I can't seem to find anything big on the web written in D. Despite the lack of known big users, D seems like a very promissing language to me, and according to TIOBE , it's fairly popular. I'm using D for my research work in the area of computer graphics. I and others have had papers published in our fields based on work done using D. I think it's definitely ready for use on small to medium sized research projects where performance matters. It's a nice fit for research work because often you're starting

Does there exist a future/promise equivalent from the C++ world in the D world? Sure there is std.parallelism but it's doesn't have exactly the functionality of the promise/future combination (there is no equivalent to get the future or the set the result or the exception, you can't also wait for completion). I believe you did not seriously look at std.parallelism ... Equivalent to "get the future" (if by that you mean the std::future 's get() method) are yieldForce(), spinForce() and workForce(). Read about these more carefully and you will see that you can wait for completion as well... std:

I'm having a very strange issue with a D program. read(" %s", variable) works fine by itself and readln(variable) works fine by itself, but when I put the two together, readln() appears to be passed over. The error occurred using both gdc and dmd. import std.stdio; import std.string; void main() { int x; write("Enter a number: "); readf(" %s", &x); write("What is your name? "); string name=chomp(readln()); writeln("Hello ", name, "!"); } Output: Enter a number: 5 What is your name? Hello ! However, if I comment out readf(" %s", &x), readln is called as I desire: Enter a number: What is your

I'm new to programming in D. What are the pros and cons of choosing either DMD (2.061) or GDC (4.6, 4.7 or 4.8, snapshot). And what GDC version should I pick? I've successfully built a recent snapshot of GCC-4.8 and GDC-4.8 and it compiles a hello world program. Here are my thoughts on pros so far: GDC : More platforms, run-time performance DMD : compilation-performance, more tested? What about debugging support through GDB - does it differ between GDC and DMD? Michal Minich Use DMD as it is the reference implementation and is most widely used. It is also the most up to date as new features

When should I define a type as a struct or as a class? I know that struct are value types while classes are reference types. So I wonder, for example, should I define a stack as a struct or a class? Reason #1 to choose struct vs class: classes have inheritance, structs do not. If you need polymorphism, you must use classes. Reason #2: structs are normally value types (though you can make them reference types if you work at it). Classes are always reference types. So, if you want a value type, choose a struct. If you want a reference type, it's easiest to go with a class. Reason #3: If you have
