Re: Is there a std.zip.ZipArchive isDir or isFile method?

I'm using std.zip.ZipArchive to read zip files, e.g.:
    auto zip = new ZipArchive(read(filename));

    foreach (name, member; zip.directory) {
        if (name.endsWith('/')) // skip dirs
            continue;
        mkdirRecurse(dirName(name));
        zip.expand(member);
        write(name, member.expandedData());
    }

As you can see, I am detecting directories with a crude test.

I really wish there was a method for this: and if there is, 
could you give me the link 'cos I can't see one in the docs?

(BTW The code above is slightly simplified: the real code won't 
unzip if there's an absolute path or .. present and also 
ensures that all members are unzipped into a subdir even if the 
zip has top-level names.)

I couldn't find one either, I had to do this:

version(Windows) {
        enum uint FILE_ATTRIBUTE_DIRECTORY = 0x10;
}
auto zip = new ZipArchive(buffer);
foreach (fn, am; zip.directory) {
        if (am.fileAttributes & FILE_ATTRIBUTE_DIRECTORY)
                ... is directory
        else
                ... is file
}

As I'm looking at my code for this I'm also reminded that 
different zip files can internally store path separators as 
either \ or / depending on the platform that created them so you 
may need to be careful about that too.  I have a bit for this 
that simply does:
version(StandardizePathSeparators) {
        string filename = fn.replace("\\", "/");
} else {
        string filename = fn;
}
