如何使用 Perl 在 Windows 上创建 Unicode 目录? [英] How do I create a Unicode directory on Windows using Perl?

问题描述

我努力创建包含 Unicode 的目录名称.我使用的是 Windows XP 和 Perl Camelbox 5.10.0.

I struggle to create directory names containing Unicode. I am on Windows XP and Perl Camelbox 5.10.0.

到目前为止，我曾经使用 File::Path qw ( make_path ) 来创建目录 - 在第一个西里尔文目录出现之前它一直工作正常.

Up until now I used to use File::Path qw ( make_path ) to create directories - which worked fine until the first cyrillic directory appeared.

对于文件 Win32API::File qw ( CreateFileW ) 如果文件名是 UTF-16LE 编码，则工作正常.目录有没有类似的东西?或者也许是一个参数来告诉 CreateFileW 如果它不存在则创建 Unicode 路径?

For files Win32API::File qw ( CreateFileW ) works fine if the file name is UTF-16LE encoded. Is there something similar for directories? Or maybe a parameter to tell CreateFileW to create the Unicode path if it doesn't exist?

谢谢，
内尔

推荐答案

Win32.pm为 CreateDirectory 和朋友提供一个接口:

Win32.pm provides an interface to CreateDirectory and friends:

Win32::CreateDirectory(DIRECTORY)

创建 DIRECTORY 并在成功时返回真值.在失败时检查 $^E 以获取扩展错误信息.

Creates the DIRECTORY and returns a true value on success. Check $^E on failure for extended error information.

DIRECTORY 可能包含系统代码页之外的 Unicode 字符.创建目录后，您可以使用 Win32::GetANSIPathName() 获取可以传递给系统调用和外部程序的名称.

DIRECTORY may contain Unicode characters outside the system codepage. Once the directory has been created you can use Win32::GetANSIPathName() to get a name that can be passed to system calls and external programs.

上一个答案:

注意:将其保留在此处作为记录，因为您试图直接在您的程序中使用 CreateDirectoryW.

Previous answer:

Note: Keeping this here for the record because you were trying to use CreateDirectoryW directly in your program.

要手动执行此操作，请导入 CreateDirectoryW 使用 Win32::API:

To do this by hand, import CreateDirectoryW using Win32::API:

Win32::API->Import(
    Kernel32 => qq{BOOL CreateDirectoryW(LPWSTR lpPathNameW, VOID *p)}
);

您需要对 CreateDirectoryW 的 $path 进行编码:

You need to encode the $path for CreateDirectoryW:

#!/usr/bin/perl

use strict; use warnings;
use utf8;

use Encode qw( encode );
use Win32::API;

Win32::API->Import(
    Kernel32 => qq{BOOL CreateDirectoryW(LPWSTR lpPathNameW, VOID *p)}
);

binmode STDOUT, ':utf8';
binmode STDERR, ':utf8';

my $dir_name = 'Волгогра́д';

my $ucs_path = encode('UCS-2le', "$dir_name");
CreateDirectoryW($ucs_path, undef)
    or die "Failed to create directory: '$dir_name': $^E";

E:> dir
2010/02/02  01:05 PM              волгогра́д
