I'm trying to use the LuaD library right now... unfortunately, I've run into somewhat of a roadblock.

This doesn't work (assertion failure in dmd's backend/cgcs.c:351, which has apparently something to do with bitops... there's an assert(0) there and I'm not really sure why).

  import luad.all;

  struct Position {
	double x,y;
  }

  void main() {
	auto state = new LuaState;
	state.doString("pos = {x = 1, y = 2}");
	auto pos = state.get!Position("pos");
  }

but this does (note that state.get!(...) simply delegates to state.globals.get!(...)).

import luad.all;

struct Position {
	double x,y;
}

void main() {
	auto state = new LuaState;
	state.doString("pos = {x = 1, y = 2}");
	auto pos = state.get!Position("pos");
}

I'm not sure what's the cause and I don't know enough about dmd's internals to make an educated guess, but I'm pretty sure this is a bug in dmd and not in LuaD.

Sorry, I'm not sure how to edit posts, it's 6am and I kinda didn't get any sleep yet, so excuse me if I'm a bit confused right now. The second example was supposed to be state.globals.get!.

Indeed it is a DMD regression. I haven't been able to reduce it yet, so your example is intriguing. It's pretty much a total blocker for using LuaD in 2.064.

It's not possible to edit posts. There are multiple interfaces to this newsgroup (NNTP, mailing list, and web forum), and the ability to edit posts would not work with that. So, replying to your own post with corrected information is the best that you can do.

This is why I wish the web interface had never been called a "forum" in the first place. According to the common usage of that word on the internet, it isn't. People have certain expectations of forum software. When newcomers start using the web interface, they have no idea that it's essentially a web-based newsgroup client and not an actual web forum that can support all the features they expect.

This is not the first time I've seen someone lost about how to edit their "forum" posts.

We should just call it a newsgroup. Or a mailing list. I prefer the latter, since it's clear that once the mail is sent out, you can't "unsend" it to make further corrections.

Well, it does not really matter how we call it if domain is still "forum.dlang.org" ;)

Um yeah... I really don't mean to be disrespectful, but I don't
think this is the place to discuss terminology.
