#dlang — Public Fediverse posts

New #blog post arrives!

I discovered that, unlike what the documentation says, you in fact do not need GDC to bootstrap GDC.

surprised Walter Bright didn't get a mention, seems to me he had something to do with how early c++ "just spread" #dlang

During the pandemic lockdowns, I did the first "Ray Tracing in One Weekend" book in D (#dlang).

I thought it'd be fun to continue with the second book. I now wasted so many hours trying to get this working again (both on macOS and a Linux container) that it's probably quicker to rewrite it in another language and forget about D. Shame.

@soulsource it’s worse than that. Non-destructive moves, while definitely an improvement on the semantic horror of auto_ptr, force us to have objects with an “empty” state, repeating the billion dollar mistake again and again… Rust is so much better in that respect that it isn’t funny

Self-referential legacy objects could probably even have been made movable by introducing something akin to D’s post-blit operator (but for moves)

So thinking about asyncronous programming again and how I probably need to ditch #dlang's GC if I want performance and then it hit me:

Why tf is std.socket.Socket an heap-allocated, gc'd class to begin with?!?!

It dosn't uses syncronized that would require a classes monitor, nor does it hold any significant amount of data.

• a socket_t (fancy 32-bit fd)
• a ushort-enum for the address family (16-bit)
• and an bool under windows, which in an asyncronous context we could remove since all will always be non-blocking

So in sum it holds 48-bit of data, while an pointer on modern systems will always be 64-bit (classes are always pointers / by ref in dlang).

Sure, it "uses" inheritance for 2 wrapper types TCPSocket and UDPSocket, which dont actually do anything other than pre-filling the type/protocol arguments in the constructor, which dont even survive after the call to socket(2)...

Is the std really that badly engineered at times or am I going crazy???

Currently working (again) on my async framework in #dlang

I need to say coming back to #dlang after a extensive while of #rust coding, I do miss a lot of features of rust already (tho it's nice for once not fighting against the borrow checker or some strange tokio bugs), like choice-types, pattern matching and traits.

Tho it's nice to just have an decent gc and not the need of wrapping everything in `Arc<RefCell<Box<T>>>` /s

Got plenty of ideas for my async framework after working with tokio (and reading parts of it and mio).

About 8 years ago I tried to convert Titanion (a 2.5D shooter game by Kenta Cho) from #dlang to #rust as a means to learn Rust and make the game open to more developers. The porting effort was also done in part as a live coding session at @OpenLabAugsburg. After about three month of intense head scratching I gave up because the Rust borrow checker does not like spaghetti code and I was a beginner. Now I tried again but with C++. I succeeded. So here it is: https://github.com/mwarning/titanion

A new #blog post appears!

I discovered that the GNU D compiler has been broken on FreeBSD 14 for over a year and it seems no one noticed. Let's discover the issue and brainstorm some solutions to it.

A great case study for why operating system package maintainers matter.
