digitalmars.D.bugs - Possible bug in std.file.listdir (Linux)

Hi!

Maybe I'm wrong, but I think I discovered a bug in std.file.listdir.

-- [snip] --

import std.file;
import std.path;
import std.stdio;

int main(char[][] args)
{
        char Files[][]=listdir(curdir);
        
        foreach(char File[]; Files)
        {
                writefln(File);
        }

        return 0;
}

-- [snip] --

This works fine unless there is a file with a '%' in it's name in the
current folder. If I put a file called for example "now_i_test%dmd" there,
the program prints

now_i_testError: std.format

and exits.

I have only tested it on Linux (Ubuntu 6.10 x86).

Best regards,
Timo

Nothing to do with std.file.listdir, just with your use of writefln. 
writefln treats strings as format strings, except when a previous format 
string told it to treat it literally. Try this one:

writefln("%s", File);

There have long been requests for write & writeln (without the 'f') that 
  just print out everything using the default formatting, but so far 
they haven't been implemented[1].


[1]: At least, in Phobos. I don't know about Ares/Mango/Tango.

Sorry, I was blind. Works fine now. :) 

Thanks for your fast reply, Frits. 

Best regards,

I think you mean "it hasn't been deemed fit for inclusion", it has been 
implemented multiple times by third parties. Basically it's a boolean...
It's a pity that writeln and readln didn't make into DMD 1.0, I think.

Speaking of the underwhelming maintenance effort being put into the 
current standard library, what about our hope for salvation?  The one 
that will have us all doing latin dances in the hallways?

Yes, the one they call "TANGO"!

Wasn't it supposed to be hitting the streets about now?
Any updates on the ETA if it ain't gonna be today?

Right, now that you mention it I *do* remember someone having written a 
patch.
What was probably fresh in my mind as I wrote that was that just 
yesterday DMD caught me leaving out the 'f' again and complained about 
an unknown identifier :(.
