Idiom #107 Get folder containing current program

Assign to string dir the path of the folder containing the currently running executable.
(This is not necessarily the working directory, though.)

dir = __dir__
import std.path;
void main(string[] args) {
    string dir = args[0].dirName;
}

import "os"
import "path/filepath"
programPath := os.Args[0]
absolutePath, err := filepath.Abs(programPath)
if err != nil {
	return err
}
dir := filepath.Dir(absolutePath)
import System.Environment (getExecutablePath)
import System.FilePath.Windows
dir <- takeDirectory `fmap` getExecutablePath
import System.Environment (getExecutablePath)
import System.FilePath.Windows
import System.IO.Unsafe (unsafePerformIO)
dir = unsafePerformIO (takeDirectory `fmap` getExecutablePath)
$dir = realpath(dirname(__FILE__));
dir := extractfilepath(paramstr(0));
