          Issue ID: 15771
           Summary: FileLogger should create the output directory if it
                    does not exist
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos

          Reporter: minasm1...@gmail.com

Currectly, this throws an exception, because the folder "oops" does not exist.

//
import std.experimental.logger;

void main()
{
    auto logger = new FileLogger("/home/minas/oops/log.txt");
}
//

std.exception.ErrnoException@std/stdio.d(393): Cannot open file
`/home/minas/oops/log.txt' in mode `a' (No such file or directory)



The solution is simple: mkdirRecurse("/home/minas/oops/");
However, this is something that the logging system should be doing, not the
client programmer.

(As an example Java's logback and log4j create the directory structure if it's
not there).
