使用tar归档读取和写入整个目录(标准库)

问题描述

这是链接的问题的延续.

在我看来， std/archive/tar.ts 模块的当前实现允许对每个文件进行读写，而不能对整个目录进行读写.

It seems to me, that current implementation of the std/archive/tar.ts module only allows reads and writes per file and not for whole directories.

到目前为止，我的参考文献是测试文件，仅显示了案例单个文件处理.但是，例如，如果给出了包含多个文件的目录./my-dir/和tar归档文件./test.tar怎么办?

So far, my reference source are the test files, which only show case single file processing. But what if, for example, a directory ./my-dir/ with multiple files and a tar archive ./test.tar is given.

然后我该如何利用 append ， extract &公司能否有效地将./my-dir/写入./test.tar存档并从中读取所有文件内容?

How can I then utilize append, extract & Co. to efficiently write ./my-dir/ to ./test.tar archive and read all file contents back from it?

推荐答案

您可以使用std/fs/walk

import { walk, walkSync } from "https://deno.land/std/fs/walk.ts";
import { Tar } from "https://deno.land/std/std/archive/tar.ts";

// Async
const tar = new Tar();

for await (const entry of walk("./dir-to-archive")) {
    if (!entry.isFile) {
        continue;
    }
    await tar.append(entry.path, {
        filePath: entry.path,
    });
}

const writer = await Deno.open("./test.tar", { write: true, create: true });
await Deno.copy(tar.getReader(), writer);

Untar文件夹/多个文件的实现已损坏.

Untar implementation for folders/multiple files is broken.
