Captures error

[gabihodoroaga]

Hi,

I'm trying to use captures and I get the following error:

            root.main();

for this test

test "url test 2" {
    var gpa = std.heap.DebugAllocator(.{}).init;
    const allocator = gpa.allocator();

    var re = try Regex.compile(allocator, "^(([a-z]+)*(:[a-z]+)*@)?(([a-z]+))(:[\\d]+)*$");
    const captures = try re.captures("testuser@localhost:2222");

    if (captures) |c| {
        for (0..7) |i| {
            if (c.sliceAt(i)) |data| {
                print("slice at {} {s}\n", .{ i, data });
            }
        }
    }
}

Is failing for the optional capturing groups.

For this input testuser:testpass@localhost:2222 the test does not fail.

Thanks,
