I haven't announced my keynote yet, but it's about various ways of handling errors and their tradeoffs. This has inspired some spirited debate in the D forums! I'm looking forward to engaging with everyone.

Ages ago in C++ there was the hope of having the standard library give more error codes and use error values instead of full exceptions. Zig has some excellent innovations in that direction, any hope of that in D?

Edit: I think it was called "Herbception"s after Herb Sutter, and it really sounded like a good idea to me

It's been a while since I looked at Zig. I couldn't say anything intelligent about it without some study.

I used to be a big fan of C++ exceptions, but eventually soured on it for various reasons. Here's an article partially addressing it from a while back:

would you ever do an SF edition? would be happy to host for you. i do a lot of conferences.

Going to include the common lisp condition system in the comparison?

WalterBright•about 1 hour ago

I tried Lithp a couple times, but it never caught on with me. I wouldn't know what the best techniques for Lithp error handling would be.

I can never get past the ugly syntax.

First day seems very LLM heavy, and sounds quite odd for Phobos 3. I would like to see Phobos 3 be more betterC forward, since I have found D to be nicer than C for WASM, but you can't use most nice things. Having a default RAII vector class for betterC and a hashmap would be super nice too.

Edit: Also would be nice to adopt move and copy semantics even closer to C++ and maybe need less explicit moves, and ideally less mess with calling __xdtor when trying to do RAII

we shipped druntime on emscripten on the opend side almost two years ago, supporting everything but threads and exceptions (i tested on emcc 3.1.69, i heard a later version of emscripten broke, im not sure). see my blog post from release time: https://dpldocs.info/this-week-in-arsd/Blog.Posted_2024_10_2...

there's a contributor working with both upstream and opend adding wasi support as well, and he also got exception support working, we'll probably ship that next month.

so the full d story on wasm is progressing too.

What exactly is the openD Canon D split about, and as a regular person, which one should I use? Any other details you could give, or background? I haven't followed any of that and have no clue.

I don't know why but dlang continues to draw me - I've really enjoyed many of the talks in the past

swyx•25 minutes ago

for those (like me) completely new but interested in new programming languages - can you or similar minds summarize the current appeal?

zem•19 minutes ago

it's an evolutionary (as opposed to revolutionary) language; it is in many ways a reimagining of c++ based on decades of observing the latter's flaws and weaknesses in the real world. if you're in the c or c++ ecosystem already you will likely find D a pleasant set of improvements to c++.

Good language.

WalterBright•about 2 hours ago

Most elegant language!
