d林操删空目录

原文

import std.exception;
import std.file;
import std.path;
import std.stdio;

void ls()
{
    foreach (e; dirEntries(absolutePath("./deleteme"), SpanMode.breadth)) {
        writeln(e.name);
    }
}

void main()
{
    "./deleteme".rmdirRecurse.collectException;
    "./deleteme".mkdir();

    writeln("empty");
    ls();

    writeln("only a directory");
    mkdir("./deleteme/a");
    ls();

    writeln("directory and file");
    std.file.write("./deleteme/a/x", "");
    ls();
}

如下:

import std.stdio;
import std.file;

void main (string [] args)
{
   auto de = dirEntries (args[1], SpanMode.breadth);
   foreach (e; de)
      writeln(e.name);
}
