In the document of std.getopt.getopt it recognizes enum types but the following
code does not work in dmd v2.064-devel-de68798 on Linux 64bit.

---
import std.getopt;

void main()
{
    auto args = ["--color=yes"];

    // The following code is in the document of getopt
    enum Color { no, yes }
    Color color; // default initialized to Color.no
    getopt(args, "color", &color);

    assert(color == Color.yes); // failed!
}

The problem is that args[0] is expected to be the program name, so std.getopt
does not try to parse it as an option. If you replace the declaration of args
with this:

    auto args = ["program.exe", "--color=yes"];

then the code works as expected.

Thank you for your comment.

After fixing args, I confirmed it works as expected.

BTW,
 The problem is that args[0] is expected to be the program name,
is it described in the document? I did not find it. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
