# tar-stream
tar-stream is a streaming tar parser and generator and nothing else. It is streams2 and operates purely using streams which means you can easily extract/parse tarballs without ever hitting the file system.
Note that you still need to gunzip your data if you have a `.tar.gz`. We recommend using [gunzip-maybe](https://github.com/mafintosh/gunzip-maybe) in conjunction with this.
```
npm install tar-stream
```
[![build status](https://secure.travis-ci.org/mafintosh/tar-stream.png)](http://travis-ci.org/mafintosh/tar-stream)
[![License](https://img.shields.io/badge/license-MIT-blue.svg)](http://opensource.org/licenses/MIT)
## Usage
tar-stream exposes two streams, [pack](https://github.com/mafintosh/tar-stream#packing) which creates tarballs and [extract](https://github.com/mafintosh/tar-stream#extracting) which extracts tarballs. To [modify an existing tarball](https://github.com/mafintosh/tar-stream#modifying-existing-tarballs) use both.
It implementes USTAR with additional support for pax extended headers. It should be compatible with all popular tar distributions out there (gnutar, bsdtar etc)
## Related
If you want to pack/unpack directories on the file system check out [tar-fs](https://github.com/mafintosh/tar-fs) which provides file system bindings to this module.
## Packing
To create a pack stream use `tar.pack()` and call `pack.entry(header, [callback])` to add tar entries.
``` js
var tar = require('tar-stream')
var pack = tar.pack() // pack is a streams2 stream
// add a file called my-test.txt with the content "Hello World!"
pack.entry({ name: 'my-test.txt' }, 'Hello World!')
// add a file called my-stream-test.txt from a stream
var entry = pack.entry({ name: 'my-stream-test.txt', size: 11 }, function(err) {
// the stream was added
// no more entries
pack.finalize()
})
entry.write('hello')
entry.write(' ')
entry.write('world')
entry.end()
// pipe the pack stream somewhere
pack.pipe(process.stdout)
```
## Extracting
To extract a stream use `tar.extract()` and listen for `extract.on('entry', (header, stream, next) )`
``` js
var extract = tar.extract()
extract.on('entry', function(header, stream, next) {
// header is the tar header
// stream is the content body (might be an empty stream)
// call next when you are done with this entry
stream.on('end', function() {
next() // ready for next entry
})
stream.resume() // just auto drain the stream
})
extract.on('finish', function() {
// all entries read
})
pack.pipe(extract)
```
The tar archive is streamed sequentially, meaning you **must** drain each entry's stream as you get them or else the main extract stream will receive backpressure and stop reading.
## Headers
The header object using in `entry` should contain the following properties.
Most of these values can be found by stat'ing a file.
``` js
{
name: 'path/to/this/entry.txt',
size: 1314, // entry size. defaults to 0
mode: 0644, // entry mode. defaults to to 0755 for dirs and 0644 otherwise
mtime: new Date(), // last modified date for entry. defaults to now.
type: 'file', // type of entry. defaults to file. can be:
// file | link | symlink | directory | block-device
// character-device | fifo | contiguous-file
linkname: 'path', // linked file name
uid: 0, // uid of entry owner. defaults to 0
gid: 0, // gid of entry owner. defaults to 0
uname: 'maf', // uname of entry owner. defaults to null
gname: 'staff', // gname of entry owner. defaults to null
devmajor: 0, // device major version. defaults to 0
devminor: 0 // device minor version. defaults to 0
}
```
## Modifying existing tarballs
Using tar-stream it is easy to rewrite paths / change modes etc in an existing tarball.
``` js
var extract = tar.extract()
var pack = tar.pack()
var path = require('path')
extract.on('entry', function(header, stream, callback) {
// let's prefix all names with 'tmp'
header.name = path.join('tmp', header.name)
// write the new entry to the pack stream
stream.pipe(pack.entry(header, callback))
})
extract.on('finish', function() {
// all entries done - lets finalize it
pack.finalize()
})
// pipe the old tarball to the extractor
oldTarballStream.pipe(extract)
// pipe the new tarball the another stream
pack.pipe(newTarballStream)
```
## Saving tarball to fs
``` js
var fs = require('fs')
var tar = require('tar-stream')
var pack = tar.pack() // pack is a streams2 stream
var path = 'YourTarBall.tar'
var yourTarball = fs.createWriteStream(path)
// add a file called YourFile.txt with the content "Hello World!"
pack.entry({name: 'YourFile.txt'}, 'Hello World!', function (err) {
if (err) throw err
pack.finalize()
})
// pipe the pack stream to your file
pack.pipe(yourTarball)
yourTarball.on('close', function () {
console.log(path + ' has been written')
fs.stat(path, function(err, stats) {
if (err) throw err
console.log(stats)
console.log('Got file info successfully!')
})
})
```
## Performance
[See tar-fs for a performance comparison with node-tar](https://github.com/mafintosh/tar-fs/blob/master/README.md#performance)

# bl *(BufferList)*
[![Build Status](https://travis-ci.org/rvagg/bl.svg?branch=master)](https://travis-ci.org/rvagg/bl)
**A Node.js Buffer list collector, reader and streamer thingy.**
[![NPM](https://nodei.co/npm/bl.png?downloads=true&downloadRank=true)](https://nodei.co/npm/bl/)
[![NPM](https://nodei.co/npm-dl/bl.png?months=6&height=3)](https://nodei.co/npm/bl/)
**bl** is a storage object for collections of Node Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them!
The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently.
```js
const BufferList = require('bl')
var bl = new BufferList()
bl.append(new Buffer('abcd'))
bl.append(new Buffer('efg'))
bl.append('hi') // bl will also accept & convert Strings
bl.append(new Buffer('j'))
bl.append(new Buffer([ 0x3, 0x4 ]))
console.log(bl.length) // 12
console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij'
console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'
console.log(bl.slice(3, 6).toString('ascii')) // 'def'
console.log(bl.slice(3, 8).toString('ascii')) // 'defgh'
console.log(bl.slice(5, 10).toString('ascii')) // 'fghij'
// or just use toString!
console.log(bl.toString()) // 'abcdefghij\u0003\u0004'
console.log(bl.toString('ascii', 3, 8)) // 'defgh'
console.log(bl.toString('ascii', 5, 10)) // 'fghij'
// other standard Buffer readables
console.log(bl.readUInt16BE(10)) // 0x0304
console.log(bl.readUInt16LE(10)) // 0x0403
```
Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**:
```js
const bl = require('bl')
, fs = require('fs')
fs.createReadStream('README.md')
.pipe(bl(function (err, data) { // note 'new' isn't strictly required
// `data` is a complete Buffer object containing the full data
console.log(data.toString())
}))
```
Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream.
Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!):
```js
const hyperquest = require('hyperquest')
, bl = require('bl')
, url = 'https://raw.github.com/rvagg/bl/master/README.md'
hyperquest(url).pipe(bl(function (err, data) {
console.log(data.toString())
}))
```
Or, use it as a readable stream to recompose a list of Buffers to an output source:
```js
const BufferList = require('bl')
, fs = require('fs')
var bl = new BufferList()
bl.append(new Buffer('abcd'))
bl.append(new Buffer('efg'))
bl.append(new Buffer('hi'))
bl.append(new Buffer('j'))
bl.pipe(fs.createWriteStream('gibberish.txt'))
```

<a name="ctor"></a>
### new BufferList([ callback | Buffer | Buffer array | BufferList | BufferList array | String ])
The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream.
Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object.
`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
```js
var bl = require('bl')
var myinstance = bl()
// equivilant to:
var BufferList = require('bl')
var myinstance = new BufferList()
```
--------------------------------------------------------
<a name="length"></a>
### bl.length
Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list.
--------------------------------------------------------
<a name="append"></a>
### bl.append(Buffer | Buffer array | BufferList | BufferList array | String)
`append(buffer)` adds an additional buffer or BufferList to the internal list. `this` is returned so it can be chained.
--------------------------------------------------------
<a name="get"></a>
### bl.get(index)
`get()` will return the byte at the specified index.
--------------------------------------------------------
<a name="slice"></a>
### bl.slice([ start, [ end ] ])
`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer.
--------------------------------------------------------
<a name="shallowSlice"></a>
### bl.shallowSlice([ start, [ end ] ])
`shallowSlice()` returns a new `BufferList` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
No copies will be performed. All buffers in the result share memory with the original list.
--------------------------------------------------------
<a name="copy"></a>
### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ])
`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively.
--------------------------------------------------------
<a name="duplicate"></a>
### bl.duplicate()
`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example:
```js
var bl = new BufferList()
bl.append('hello')
bl.append(' world')
bl.append('\n')
bl.duplicate().pipe(process.stdout, { end: false })
console.log(bl.toString())
```
--------------------------------------------------------
<a name="consume"></a>
### bl.consume(bytes)
`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers&mdash;initial offsets will be calculated accordingly in order to give you a consistent view of the data.
--------------------------------------------------------
<a name="toString"></a>
### bl.toString([encoding, [ start, [ end ]]])
`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information.
--------------------------------------------------------
<a name="readXX"></a>
### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8()
All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently.
See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work.
--------------------------------------------------------
<a name="streams"></a>
### Streams
**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **bl** instance.

# end-of-stream
A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
npm install end-of-stream
## Usage
Simply pass a stream and a callback to the `eos`.
Both legacy streams, streams2 and stream3 are supported.
``` js
var eos = require('end-of-stream');
eos(readableStream, function(err) {
// this will be set to the stream instance
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended', this === readableStream);
});
eos(writableStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has finished', this === writableStream);
});
eos(duplexStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended and finished', this === duplexStream);
});
eos(duplexStream, {readable:false}, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has finished but might still be readable');
});
eos(duplexStream, {writable:false}, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended but might still be writable');
});
eos(readableStream, {error:false}, function(err) {
// do not treat emit('error', err) as a end-of-stream
});
```
