I was listing some files in a directory using listdir and then printing out the
names using writefln, but the program kept terminating before finishing printing
all the contents.  I finally figured out it was because in one of the filenames
there was a percent sign.

So, running the following program on DMD 0.146 will produce a FormatError:







How can I get around this?

I'm running Windows XP SP2 and I tried the command chcp 65001 to set my console
to UTF-8 thinking that might be it, but no go.  Then I piped this to a file and
lo and behold, the output stopped in the file at the same point on the console.

Any help on this would be much appreciated?

I ran into this before :)
I think there really should be a _standard_ writeraw() or just write() 
(with no f) which does exactly that ..

void writer( char[] x )
{
     writef("%s", x);
}

Yep, and writeln, but you could just use dout.writeString() /  
dout.writeLine().

Perhaps the formatting should allow '%%' to represent a single percent sign?

It does.  writefln("5%%") outputs "5%."  The problem is that he wants to 
print out arbitrary strings which may have single percent signs, and he 
doesn't want format() interpreting the percent signs as format specifiers.

You could always just write such a function and send it to Walter. It might
even make it to the official library.

Yup, I think we should have one such function (write and writeln) in the 
stdlib.

I wrote write, writeln, read, readln but there was no response.
(i.e. they didn't make into std.stdio, but to din/dout instead)

Will try again. Some day.
