# Usage
## Tar
```ts
import { Tar } from "https://deno.land/std@$STD_VERSION/archive/tar.ts";
const tar = new Tar();
const content = new TextEncoder().encode("Deno.land");
await tar.append("deno.txt", {
reader: new Deno.Buffer(content),
contentSize: content.byteLength,
});
// Or specifying a filePath.
await tar.append("land.txt", {
filePath: "./land.txt",
});
// use tar.getReader() to read the contents.
const writer = await Deno.open("./out.tar", { write: true, create: true });
await Deno.copy(tar.getReader(), writer);
writer.close();
```
## Untar
```ts
import { Untar } from "https://deno.land/std@$STD_VERSION/archive/tar.ts";
import { ensureFile } from "https://deno.land/std@$STD_VERSION/fs/ensure_file.ts";
import { ensureDir } from "https://deno.land/std@$STD_VERSION/fs/ensure_dir.ts";
const reader = await Deno.open("./out.tar", { read: true });
const untar = new Untar(reader);
for await (const entry of untar) {
console.log(entry); // metadata
/*
fileName: "archive/deno.txt",
fileMode: 33204,
mtime: 1591657305,
uid: 0,
gid: 0,
size: 24400,
type: 'file'
*/
if (entry.type === "directory") {
await ensureDir(entry.fileName);
continue;
}
await ensureFile(entry.fileName);
const file = await Deno.open(entry.fileName, { write: true });
// <entry> is a reader.
await Deno.copy(entry, file);
}
reader.close();
```
