Slightly off topic: Is D a good language for creating tiny windows or Linux executables? There is an upcoming game jam (4mb jam 2025) which gives extra points for game submissions <= 8KB. With c you can fit a window with graphics update in an executable of less than 900 bytes[0]. Granted it's using crinkler for linking which does some compression.

Yes. Just use the “better C” mode

... which is not D any more though.

It's like saying "C is no longer C if you don't link with libc", it just is not true at all, and honestly, a pretty stupid thing to say

What essential features are missing for you?

Instead of being an ass, maybe you can take the time to educate me why you think I'm wrong?

I think that at least the garbage collection not being available qualifies my statement as somewhat being true. For game development, as it's closer to what grand-parent asked, classes not being usable would also be an issue...

For game development? I imagine having to use only structs but not classes would be something that forces a "non idiomatic D" experience. Dynamic arrays sound like something that's very useful for a game. I don't know, there are plenty of features that are incompatible with better C that makes D, D. Generally speaking, garbage collection would be the biggest in my opinion.

Yeah this person is asking how to make the smallest executable. They don’t want garbage collection.

Garbage collection was about what I would be missing. I mentioned before what could be missing from OP's point of view.

Ok. I think the better C mode is cool and I think it’s worth a try for his interest and project.

You can still use classes in BetterC - you just have to allocate them yourself. D recently acquired "placement new" which makes that more convenient.
