What is the best way to remove file name from full path?

string path = thisExePath()

Seems like "dirName" in std.path is a good candidate ;)
http://dlang.org/phobos/std_path.html#.dirName

You'll find many other path manipulation functions there.

Thanks! But if I want to strip it, how I can cut it?

I can't understand how to use strip? For example I would like to cut just extension.

path = path.stripRight("exe");
Error: no overload matches for stripRight(C)(C[] str) if

std.path.setExtension is your friend.

"stripExtension" would be your friend here.

If you want the extension, then "extension".

As a general rule, everything you need to manipulate paths and filenames is in std.path:

strip doens't work that way. It simply removes leading/trailing white.

There's a version in std.algorithm which is more generic, but it accepts either a predicate, or an element, but not a range.

Unfortunately, there is no generic function that allows striping of a specific ending range (though there are ways to either detect it, or strip it from the end).
If you want something generic, then:

    string path = "myFile.doc";
    string extension = ".doc";
    if (path.endsWith(extension))
        path = path[0 .. $ - extension.length];

Would work.

but for strings we have std.string.chomp.

I missread that documentation. I thought it removed all characters that can also be found in delim. Power to me.

ah, i just found this function (really, less than hour ago), that's why
i still remember where it is and what it's doing. ;-)
