Ethan: About your wpf/C# and D integration

2019-08-12 Thread Bert via Digitalmars-d-learn
One of the biggest issues I have with D is properly gui development. It's just a real pain in the ass compared to wpf and C#. I'm curious about what you have done and if it would let me get the best of both worlds. What I'd like to do is write the business end of apps in D and use C# for

error : outer function context of `D main` is needed to `new` nested class `main.main.X`

2019-08-14 Thread Bert via Digitalmars-d-learn
void main() { class X { ... } auto f = foo!X; } then in another module I have a templated function foo that simply new's x: auto foo(T)() { return new T; } yet I get the error. I realize that X is local to main and I realize I could do something like foo(new X); but that

Local static class fields

2019-08-12 Thread Bert via Digitalmars-d-learn
Making a field static is effectively a global variable to the class. I have a recursive class structure(think of a graph or tree) and I need to keep a global state for it, but this state actually needs to be different for each tree object. The reason for this is that structurally it will not

Shadertoy in Dcompute?

2019-08-21 Thread Bert via Digitalmars-d-learn
How hard would it be to do something like Shadertoy in Dcompute and would it be any faster? I don't like the basics of Shadertoy, lots of nonsense to do basic stuff. E.g., to work with complex numbers one must essentially do everything manually. Would there be any benefit using
