Cycle detected between modules with ctors/dtors
Hi, I am trying to compile the code that was working with dmd 2.050 using dmd 2.052. The code compiles but it gives me errors with message when trying to run: Cycle detected between modules with ctors/dtors This was not happening earlier with 2.050. I am not able to produce a smaller test case for this but it is happening with a lot of code pieces. A few scenarios in which this is happening is if a class passes its reference to child class for usage. I understand that the above might not be a fit datapoint for analysis but wanted to understand if this is known or someone else has faced this? Thanks & Regards Mandeep
Expression templates in D1
I have been trying to create some simple expression templates in D1 but I've
run into trouble. Here is a reduced test case:
class A
{
void opSub_r(T:int)(T a)
{
}
void opSub(T)(T a)
{
}
}
void main(char[][] args)
{
A a;
a - 1;
a - a; // line 20
1 - a;
}
The error is:
test.d(20): Error: template test.A.opSub_r(T : int) does not match any function
template declaration
test.d(20): Error: template test.A.opSub_r(T : int) cannot deduce template
function from argument types !()(A)
My goal is to adjust the code such that the three expressions in the main
function all compile. Both opSub's must be templated functions (as far as I can
tell) so that the expression templates can work properly. Here is my full code,
incidentally:

Any ideas of any workabouts? Has anyone done expression templates in D1 and got
them to work?
And yes... the code above works fine in D2, but I want to try to get it to work
in D1 for now.
Thanks,

Actually, for ISO 8601, which the library follows, there _is_ a year 0. Date, DateTime, and SysTime all have the function yearBC which will give you the year as you would normally expect (1 B.C. being immediately prior to 1 A.D. with no year 0). But the ISO standard calls for a year 0, and I followed the standard (it's also way easier to deal with programmatically). So, other than the yearBC function, it treats 0 as the year prior to 1 A.D., and the years prior to 0 are negative. - Jonathan M Davis

I've been looking for guidance on how to do web applications in D but I haven't found anything. My background is not C/C++ but Java (and Delphi many years ago) so I have not only a new language but a new culture to get used to as well. Could somebody give me some pointers? Thanks Jaime The simplest way to make a web application with D is to use CGI/FastCGI etc. There are also at least two frameworks in development (that I know of), one is significantly more developed. http://arsdnet.net/dcode/ - see web.d, cgi.d etc, this is the most mature (that I know of). https://github.com/mrmonday/serenity - One I'm working on. It's due to undergo significant changes and is lacking a lot of basic functionality, so I'd avoid it, for now at least. -- Robert http://octarineparrot.com/
Re: Next Release
Well, then I'd better make sure that I get my most recent updates to std.datetime in soon. - Jonathan M Davis Does your library take into account that there's no year 0?
