The description is ambiguous when one or both operands of / are negative. So, in other words, what does D return from: 3 / 2 3 / -2 -3 / 2 -3 / -2 Such information should be part of the language specification. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

[Issue 2716] Confusion of auto and scope as the class attribute

Do not consider auto to mean scope.
This is a patch against LDC's DMDFE. It removes the remaining instances of auto
meaning scope and makes 'auto class C { ... }' and 'auto C c;' an 'Error:
storage class has no effect: auto'. See also bug 3118 .

[Issue 3168] New: Declaring structs as incomplete types no longer works
http://d.puremagic.com/issues/show_bug.cgi?id=3168 Summary: Declaring structs as incomplete types no longer works Product: D Version: 1.046 Platform: All OS/Version: All Status: NEW Severity: regression Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: nfx...@gmail.com In dmd 1.045, you used to be able to declare structs like this: struct FT_RasterRec; This no longer works with dmd 1.046. The error message is: test.d(1): Error: struct jk.FT_RasterRec has forward references Declaring structs like this is often done in C to define incomplete types, and is especially useful when porting C headers. Also, the new behavior in dmd 1.046 breaks old code. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Also affects 1.0.
It's true that the specs don't mention it but it's a bit inconsistent that both
the pointer and scope object cases are detected while the case of array slicing
isn't. Of the following, currently only the first three result in a compile
error:
int* pointer() { int x; return x; }
Object object() { scope Object x; return x; }
int[] array() { int[1] x; return x; }
int[] slice() { int[1] x; return x[]; }

[Issue 3165] What kind of integer division does D use?

I've ran the following test:
--
import std.stdio;
int main() {
writefln(8/3);
writefln(8/(-3));
writefln((-8)/3);
writefln((-8)/(-3));
writefln(8%3);
writefln(8%(-3));
writefln((-8)%3);
writefln((-8)%(-3));
return 0;
}
--
outputs the following
--
2
-2
-2
2
2
2
-2
-2
--
So DMD uses truncated division. The quotient rounds towards zero and the
remainder has the same sign as the dividend.

[Issue 1943] Templates can't take function pointer parameters
http://d.puremagic.com/issues/show_bug.cgi?id=1943 Daniel Keep daniel.keep+d.puremagic@gmail.com changed: What|Removed |Added Keywords||spec CC||daniel.keep+d.puremagic.com ||@gmail.com --- Comment #1 from Daniel Keep daniel.keep+d.puremagic@gmail.com 2009-07-12 21:55:06 PDT --- This has just cropped up on IRC. Either the compiler should be fixed to match the spec, or the spec should be changed to match the compiler's behaviour. The simplest thing to do would be to change to spec to indicate that only strings, ints and floats are allowed as value parameters. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
