+# bl *(BufferList)*
+
+**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 ])
+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)
+`append(buffer)` adds an additional buffer or BufferList to the internal list.
+
+--------------------------------------------------------
+<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="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.

+***Node-core streams for userland***
+
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png?&months=6&height=3)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.
