Ok, looks like printf is in fact in the stdio module. It's also in object.
I guess this isn't a problem.
However I seem unable to get printf to print out long (64-bit) ints, either
in decimal or in hex.
printf("big hex num = %lx\n",~0ul);
printf("big dec num = %lu\n",~0ul);
Am I being an idiot?

Awesome. You see, this would be great to have on a webpage somewhere. Along with %.s and everything else that's different from C. It'd be great if it just *knew* it was a 64-bit int automatically, and all you have to specify was the formatting.

No, that would be a bad idea, since unless it knew ahead of time how big to make the staging area it'd end up allocating lots of memory during the concatenation, and doing more work than it has to. This is what streams are for. Streams != Arrays. Streams are more like a buffered circular queue. .toString is nice to have, also, btw. And some kind of stream that streams into a string (a string "staging area", or string "construction zone", if you will) would be quite handy. But for general I/O you really want a stream. Someone was working on something like this. There's a stream module in Phobos; I remember a long time ago it was broken, but I haven't tried it in ages. Anyone?

This is not inefficient, since you can make the methods of this type output directly. I don't remember whether there's any particular support for 64-bit int, it can be included easily anyway. The only problem with this approach is that if you make your own overloaded structs, how do you specify their output method? Besides, i somehow think efficiency is not that important: look, C++ offers iostreams, and most programmers actually use them, despite their inefficiency. The ones who don't, have their printf still available as they know it. However, i'm pretty much sure, that people really conserned with speed would abandon any varargs function and simply output their text part by part, with simple write or something alike. An interesting thing to have would be a printf which would allow for changing order of arguments, as it usually differs in various natural languages. This can be accomplished by requiering an associative array indexed by string as a second input. This is not necessarily a consern for Phobos though, unless until it has been actually implemented by a volunteer. -i.It'd be great if it just *knew* it was a 64-bit int automatically, and all you have to specify was the formatting.We could write a module for this.

%lld is the correct one Actually %ld will work, but truncate, and if you have multiple formatted expansions within a single block it'll be nasty. "Sean L.

Write
printf("big hex num = %llx\n",~0ul);
instead (notice double 'l': %llx)
Since it works in DMC, I think it works in D.
