digitalmars.D - Bug report (sorry, couldn't register at bugzilla for some reason)

reply "Hannes Steffenhagen" <cubicentertain gmail.com> writes:
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!.

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" ;)

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.
