And more important, writefln which will save a lot \n's to the world <g>

cool. writef is nice and simple and as flexible as printf. Is someone going to add a std.stream wrapper for writef? (Sean? me?) A corresponding readf would be nice since then we could replace std.stream.scanf. It could also be worth deprecating std.stream.printf, too, though it just ends up calling C's printf so it isn't a big deal.

Although i can't get writef to work (only writefln) it is a great
improvement
over printf. BUT: Why do fwritef and fwritefln take FILE* as an argument
and not a Stream or something like that?

This works:
-----------------------------------------
C:\mars>type test.d

import std.stdio;

void main()
{
    std.stdio.writef("hello\n");
}

C:\mars>dmd test
\dm\bin\link test,,,user32+kernel32/noi;

C:\mars>test
hello

C:\mars>
----------------------------------------------

std.format.doFormat() is designed to work with anything you want.

Wow, writef() is cool! This'll make displaying information alot easier than it
was before with printf()!

writef("NUMBER: ", 3);

instead of:

printf("NUMBER: %i", 3);

Thanks, Walter (and whoever else contributed to the writef() function)!

Presumably we're going to have versions of writef for strings and Stream objects?  OK, so it would be straightforward to write them ourselves, but they'd be such common, simple operations there would otherwise be several independently-written copies around (a bit like the many copies of bubble sort that C programmers who haven't discovered how to qsort keep around...).

The obvious way would be to add writef and writefln methods to Stream (we'd have Unicode or not to consider - maybe also writefW and writeflnW), and to create a function

	dchar[] swritef(...);

(by analogy with sprintf - but still don't know if that's the best name) to return a formatted string.  I'll probably code up these additions over the weekend if nobody else is going to....

BTW there are a few kinds of types you haven't told us the default formatting for:

- characters (presumably the character itself)
- structs and unions (presumably .toString(), if it has one....)
- enums (do these count as integral types?)
- arrays other than strings
- pointers
- function pointers/delegates
- have I missed any?

The character itself.

Yup. Though this won't work yet for structs until TypeInfo is improved.

> - enums (do these count as integral types?)

Enums I have special plans for. When TypeInfo gets better, I plan to have writef write out the enum identifier corresponding to the value. Right now, they come out as integers.

> - arrays other than strings

Waiting on improved TypeInfo. Probably will do a comma separated list.

Like %p.

Walter: Bravo! I really likee the new 'C' printf() replacements in 'D',
especially the writef() and writefln() functions, which I've been converting all
the printf()s to writefln()s in my current 'D' code! :)) They work Great!!

Also v0.95 fixed the problems I had found in v0.93 and v0.94...Thxs!

<*-Hint-*>I know that I promised not to bug you, but it has been a little while now, so here goes nothing...are you any closer to putting in the ifind(), and irfind() (and maybe hopefully the ireplace() and icount() functions) into std.string? Please. I need them for the code I'm writing, and it would be a lot better if they're already in the Phobos runtime library. Plus I'm very close to announcing the opening of an expanded 'D' programming section to my home page soon, so it would be nice have the functions in place.

Don't worry, I'll get to them.
