Idiom #180 List files in directory

Create list x containing the contents of directory d.

x may contain files and subfolders.
No recursive subfolder listing.

import System.Directory (listDirectory)
do
  x <- listDirectory d
  -- do something with x
#include <dirent.h>
struct dirent ** x = NULL;
int n = scandir (p, &x, NULL, alphasort);
(def x ((comp file-seq clojure.java.io/file) d))
using System.IO
var files = Directory.GetFiles(dirPath);
import std.file;
auto x = dirEntries(d, SpanMode.shallow);

import 'dart:io';
var x = Directory(d).listSync();
import "os"
x, err := os.ReadDir(d)
const fs = require('fs');
const x = fs.readdirSync(d)

import java.io.File;
final File directory = new File(d);
final File[] x = directory.listFiles();
import java.util.ArrayList;
import java.util.Arrays;
ArrayList<File> x = (ArrayList<File>) Arrays.asList(new File(d).listFiles());
$x = scandir($d);
uses SysUtils, Classes;
if FindFirst(IncludeTrailingPathDelimiter(d) + '*', 
               faAnyFile and (not faDirectory), SR) = 0 then
repeat
  x.Add(SR.Name);
until FindNext(SR) <> 0;
FindClose(SR);
