Ben Hinkle (1/2) Jul 12 2004 yup - the OP said they were on Linux. The Windows version is fine.

Matthew (3/24) Jul 12 2004 Why not use std.recls?

Matthew (3/8) Jul 12 2004 Of course. I was just being practical, to get him working right now. :)

Why won't listdir() work?

This might have something to do with it. From std/file.d:

char[][] listdir(char[] pathname)
{
    assert(0);          // BUG: not implemented
    return null;
}

I can't decode the base64... the quick base64 encoder/decoder (written in D :)
that I made says that the string is invalid (I removed all of the newlines).

Can you re-post the code without using the base64 encoding?

I don't think it's base64, you might need to use uudecode on it. Here's the
file www.dprogramming.com/listdir.d . I updated it to contain the changes
made to the origional listdir() for Windows, and added a finally block for
the cleanup code in case an exception is thrown during the callback. The
code is donated to the public domain.

No, becuase on mine the function is this:

char[][] listdir(char[] pathname)
{
char[][] result;
char[] c;
HANDLE h;

c = std.path.join(pathname, "*.*");
if (useWfuncs)
{
WIN32_FIND_DATAW fileinfo;

h = FindFirstFileW(std.utf.toUTF16z(c), &fileinfo);
if (h != INVALID_HANDLE_VALUE)
{
do
{   int i;
int clength;

// Skip "." and ".."
if (std.string.wcscmp(fileinfo.cFileName, ".") == 0 ||
std.string.wcscmp(fileinfo.cFileName, "..") == 0)
continue;

i = result.length;
result.length = i + 1;
clength = std.string.wcslen(fileinfo.cFileName);
result[i] = std.utf.toUTF8(fileinfo.cFileName[0 .. clength]);
} while (FindNextFileW(h,&fileinfo) != FALSE);
FindClose(h);
}
}
else
{
WIN32_FIND_DATA fileinfo;

h = FindFirstFileA(toMBSz(c), &fileinfo);
if (h != INVALID_HANDLE_VALUE)
{
do
{   int i;
int clength;
wchar[] wbuf;
int n;

// Skip "." and ".."
if (std.string.strcmp(fileinfo.cFileName, ".") == 0 ||
std.string.strcmp(fileinfo.cFileName, "..") == 0)
continue;

i = result.length;
result.length = i + 1;
clength = std.string.strlen(fileinfo.cFileName);

//result[i] = fileinfo.cFileName[0 .. clength].dup;

// Convert cFileName[] to unicode
wbuf.length = MultiByteToWideChar(0,0,fileinfo.cFileName,clength,null,0);
n =
MultiByteToWideChar(0,0,fileinfo.cFileName,clength,cast(wchar*)wbuf,wbuf.length);
assert(n == wbuf.length);
result[i] = std.utf.toUTF8(wbuf);

} while (FindNextFileA(h,&fileinfo) != FALSE);
FindClose(h);
}
}
return result;
}

Maybe it's Windows-only?

yup - the OP said they were on Linux. The Windows version is fine.

I think listdir should work anyway, don't you?

Do you accept suggestions? I've just looked at recls and I think is great
but it _really_ need a new name (fssearch maybe?) because the current one
doesn't says nothing ;)

recls comes from RECursive LS (as in the UNIX command). I also like it
because it allows the pronunciation "reckless", which is kinda ironic. ;)

It's now way too established to change the name - it's mapped to several
