Walter, first of all, thanks for all the great work you've been doing!  You're change my life. ;-)  Again, thanks.

Ok, for the rest of the folks, out there...

So, I love the new std.file, but I don't know how to get the "struct DirEntry" to work.  Here is the help in Phobos:

|struct DirEntry;
|    Directory Entry
|
|    char[] name;
|        file or directory name
|
|    ulong size;
|        size of file in bytes
|
|    long creationTime;
|        time of file creation
|
|    long lastAccessTime;
|        time file was last accessed
|
|    long lastWriteTime;
|        time file was last written to
|
|    int isdir();
|        Return !=0 if DirEntry is a directory.
|
|    int isfile();
|        Return !=0 if DirEntry is a file.

How do I use it against a file?  (say, c:\temp\file.txt)

thanks.

Has anyone figured out how to use the DirEntry entries for std.file?

I believe DirEntry is currently only used with listdir, eg.

import std.file;
import std.stdio;

void main()
{
	bool showFile(DirEntry* e)
	{
		if (e.isdir()) return true;
		writefln("  ",e.name);
		return true;
	}
	
	bool showDir(DirEntry* e)
	{
		if (!e.isdir()) return true;
		writefln("  ",e.name);
		return true;
	}
	
	writefln("Files:");
	listdir(".",&showFile);
	writefln("");
	
	writefln("Directories:");
	listdir(".",&showDir);
	writefln("");
}

Gosh!  And I was so excited about std.file. ;-)  Well, it's a good thing that we have std.recls. I hope Walter would, someday, also support the same functions that are in DirEntry for a file.

Thanks Regan.

There was a thread recently comparing them, you should read it to get Walter and Matthews opinions on the topic.

It should be fairly simple to write a function to produce a DirEntry, you could give it a go yourself. Heck, I might give it a go if I have time. I get the impression Walter is concentrating on the compiler as opposed to Phobos at the moment which might explain why std.file is a very basic implementation at present.

You're welcome.

Go ahead, make my day. ;-)  Je je je je...

LOL :)

Here's a little something, not exactly what you wanted but you might find it useful.

main.d
etc\direntry.d
etc\stat.d

It uses 'stat' which has some limitations. I do not think it handles unicode filenames or files larger than int.max in size. MSDN defines _stati64 etc which, I believe, use M$ specific 64 bit integers to overcome the file size problem. Of course, DMC and thus DMD does not have access to these functions.

Thanks Regan. :-)
