node_modules/onoff/node_modules/epoll/README.md

+## epoll
+
+A low-level **Node.js** binding for the Linux epoll API for monitoring multiple
+file descriptors to see if I/O is possible on any of them.
+
+This module was initially written to detect EPOLLPRI events indicating that
+urgent data is available for reading. EPOLLPRI events are triggered by
+interrupt generating [GPIO](https://www.kernel.org/doc/Documentation/gpio/)
+pins. The epoll module is used by [onoff](https://github.com/fivdi/onoff)
+to detect such interrupts.
+
+epoll supports Node.js versions 0.10, 0.12, 4, 5, 6, 7, 8 and 9.
+
+## Installation
+
+Note that epoll can only be installed successfully on Linux systems. Attempting
+to install epoll on other systems will result in compile errors.
+
+    $ npm install epoll
+
+If you're using Node.js v4 or higher and seeing lots of compile errors when
+installing epoll, it's very likely that gcc/g++ 4.8 or higher are not
+installed. See
+[Node.js v4 and native addons](https://github.com/fivdi/onoff/wiki/Node.js-v4-and-native-addons)
+for details.
+
+If you're using Node.js v0.10.29 on the Raspberry Pi and seeing a compile
+error saying that `‘REPLACE_INVALID_UTF8’ is not a member of ‘v8::String’`
+see [Node.js v0.10.29 and native addons on the Raspberry Pi](https://github.com/fivdi/onoff/wiki/Node.js-v0.10.29-and-native-addons-on-the-Raspberry-Pi).
+
+If you're using Node.js v0.10.29 on the BeagleBone Black and seeing a compile
+error saying that `‘REPLACE_INVALID_UTF8’ is not a member of ‘v8::String’`
+see [Node.js v0.10.29 and native addons on the BeagleBone Black](https://github.com/fivdi/onoff/wiki/Node.js-v0.10.29-and-native-addons-on-the-BeagleBone-Black).
+
+## API
+
+  * Epoll(callback) - Constructor. The callback is called when epoll events
+    occur and it gets three arguments (err, fd, events).
+  * add(fd, events) - Register file descriptor fd for the event types specified
+    by events.
+  * remove(fd) - Deregister file descriptor fd.
+  * modify(fd, events) - Change the event types associated with file descriptor
+    fd to those specified by events.
+  * close() - Deregisters all file descriptors and free resources.
+
+Event Types
+
+  * Epoll.EPOLLIN
+  * Epoll.EPOLLOUT
+  * Epoll.EPOLLRDHUP
+  * Epoll.EPOLLPRI
+  * Epoll.EPOLLERR
+  * Epoll.EPOLLHUP
+  * Epoll.EPOLLET
+  * Epoll.EPOLLONESHOT
+
+Event types can be combined with | when calling add or modify. For example,
+Epoll.EPOLLPRI | Epoll.EPOLLONESHOT could be passed to add to detect a single
+GPIO interrupt.
+
+## Example - Watching Buttons
+
+The following example shows how epoll can be used to detect interrupts from a
+momentary push-button connected to GPIO #4 (pin P1-7) on the Raspberry Pi.
+The source code is available in the [example directory]
+(https://github.com/fivdi/epoll/tree/master/example/watch-button) and can
+easily be modified for using a different GPIO on the Pi or a different platform
+such as the BeagleBone.
+
+The first step is to export GPIO #4 as an interrupt generating input using
+the export bash script from the examples directory.
+
+    $ [sudo] ./export
+
+export:
+```bash
+#!/bin/sh
+echo 4 > /sys/class/gpio/export
+echo in > /sys/class/gpio/gpio4/direction
+echo both > /sys/class/gpio/gpio4/edge
+```
+
+Then run watch-button to be notified every time the button is pressed and
+released. If there is no hardware debounce circuit for the push-button, contact
+bounce issues are very likely to be visible on the console output.
+watch-button terminates automatically after 30 seconds.
+
+    $ [sudo] node watch-button
+
+watch-button:
+```js
+var Epoll = require('../../build/Release/epoll').Epoll,
+  fs = require('fs'),
+  valuefd = fs.openSync('/sys/class/gpio/gpio4/value', 'r'),
+  buffer = new Buffer(1);
+
+// Create a new Epoll. The callback is the interrupt handler.
+var poller = new Epoll(function (err, fd, events) {
+  // Read GPIO value file. Reading also clears the interrupt.
+  fs.readSync(fd, buffer, 0, 1, 0);
+  console.log(buffer.toString() === '1' ? 'released' : 'pressed');
+});
+
+// Read the GPIO value file before watching to
+// prevent an initial unauthentic interrupt.
+fs.readSync(valuefd, buffer, 0, 1, 0);
+
+// Start watching for interrupts.
+poller.add(valuefd, Epoll.EPOLLPRI);
+
+// Stop watching after 30 seconds.
+setTimeout(function () {
+  poller.remove(valuefd).close();
+}, 30000);
+```
+
+When watch-button has terminated, GPIO #4 can be unexported using the
+unexport bash script.
+
+    $ [sudo] ./unexport
+
+unexport:
+```bash
+#!/bin/sh
+echo 4 > /sys/class/gpio/unexport
+```
+
+## Example - Interrupts Per Second
+
+The following example shows how epoll can be used to determine the number of
+hardware interrupts that can be handled per second on the Raspberry Pi.
+The source code is available in the [example directory]
+(https://github.com/fivdi/epoll/tree/master/example/interrupts-per-second) and
+can easily be modified to use different GPIOs on the Raspberry Pi or a
+different platform such as the BeagleBone.
+
+In this example, GPIO #7 is wired to one end of a 1kΩ current limiting
+resistor and GPIO #8 is wired to the other end of the resistor. GPIO #7 is an
+input and GPIO #8 is an output.
+
+The first step is to export GPIOs #7 and #8 using the export bash script from
+the examples directory.
+
+    $ [sudo] ./export
+
+export:
+```bash
+#!/bin/sh
+echo 7 > /sys/class/gpio/export
+echo 8 > /sys/class/gpio/export
+echo in > /sys/class/gpio/gpio7/direction
+echo both > /sys/class/gpio/gpio7/edge
+echo out > /sys/class/gpio/gpio8/direction
+```
+
+Then run interrupts-per-second. interrupts-per-second toggles the state of the
+output every time it detects an interrupt on the input. Each toggle will
+trigger the next interrupt. After five seconds, interrupts-per-second prints
+the number of interrupts it detected per second.
+
+    $ [sudo] node interrupts-per-second
+
+interrupts-per-second:
+```js
+var Epoll = require('../../build/Release/epoll').Epoll,
+  fs = require('fs'),
+  inputfd = fs.openSync('/sys/class/gpio/gpio7/value', 'r+'),
+  outputfd = fs.openSync('/sys/class/gpio/gpio8/value', 'r+'),
+  value = new Buffer(1),  // The three Buffers here are global
+  zero = new Buffer('0'), // to improve performance.
+  one = new Buffer('1'),
+  count = 0,
+  time;
+
+// Create a new Epoll. The callback is the interrupt handler.
+var poller = new Epoll(function (err, fd, events) {
+  var nextValue;
+
+  count++;
+
+  // Read GPIO value file. Reading also clears the interrupt.
+  fs.readSync(inputfd, value, 0, 1, 0);
+
+  // Toggle GPIO value. This will eventually result
+  // in the next interrupt being triggered.
+  nextValue = value[0] === zero[0] ? one : zero;
+  fs.writeSync(outputfd, nextValue, 0, nextValue.length, 0);
+});
+
+time = process.hrtime(); // Get start time.
+
+// Start watching for interrupts. This will trigger the first interrupt
+// as the value file already has data waiting for a read.
+poller.add(inputfd, Epoll.EPOLLPRI);
+
+// Print interrupt rate to console after 5 seconds.
+setTimeout(function () {
+  var rate;
+
+  time = process.hrtime(time); // Get run time.
+  rate = Math.floor(count / (time[0] + time[1] / 1E9));
+  console.log(rate + ' interrupts per second');
+
+  // Stop watching.
+  poller.remove(inputfd).close();
+}, 5000);
+```
+
+When interrupts-per-second has terminated, GPIOs #7 and #8 can be unexported
+using the unexport bash script.
+
+    $ [sudo] ./unexport
+
+unexport:
+```bash
+#!/bin/sh
+echo 7 > /sys/class/gpio/unexport
+echo 8 > /sys/class/gpio/unexport
+```
+
+Here are some results from the "Interrupts Per Second" example.

+node-bindings
+=============
+### Helper module for loading your native module's .node file
+
+This is a helper module for authors of Node.js native addon modules.
+It is basically the "swiss army knife" of `require()`ing your native module's
+`.node` file.
+
+Throughout the course of Node's native addon history, addons have ended up being
+compiled in a variety of different places, depending on which build tool and which
+version of node was used. To make matters worse, now the _gyp_ build tool can
+produce either a _Release_ or _Debug_ build, each being built into different
+locations.
+
+This module checks _all_ the possible locations that a native addon would be built
+at, and returns the first one that loads successfully.
+
+
+Installation
+------------
+
+Install with `npm`:
+
+``` bash
+$ npm install bindings
+```
+
+Or add it to the `"dependencies"` section of your _package.json_ file.
+
+
+Example
+-------
+
+`require()`ing the proper bindings file for the current node version, platform
+and architecture is as simple as:
+
+``` js
+var bindings = require('bindings')('binding.node')
+
+// Use your bindings defined in your C files
+bindings.your_c_function()
+```
+
+
+Nice Error Output
+-----------------
+
+When the `.node` file could not be loaded, `node-bindings` throws an Error with
+a nice error message telling you exactly what was tried. You can also check the
+`err.tries` Array property.
+
+```
+Error: Could not load the bindings file. Tried:

+    at Function.Module._load (module.js:312:12)
+    ...
+```
+
+The searching for the `.node` file will originate from the first directory in which has a `package.json` file is found.

+## Asynchronous work helpers
+
+`Nan::AsyncWorker` and `Nan::AsyncProgressWorker` are helper classes that make working with asynchronous code easier.

+ - <a href="#api_nan_async_worker"><b><code>Nan::AsyncWorker</code></b></a>
+ - <a href="#api_nan_async_progress_worker"><b><code>Nan::AsyncProgressWorkerBase &amp; Nan::AsyncProgressWorker</code></b></a>

+
+<a name="api_nan_async_worker"></a>
+### Nan::AsyncWorker
+
+`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
+
+Definition:
+
+```c++
+class AsyncWorker {
+ public:
+  explicit AsyncWorker(Callback *callback_);
+
+  virtual ~AsyncWorker();
+
+  virtual void WorkComplete();
+
+  void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(const v8::Local<v8::String> &key,
+                        const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(uint32_t index,
+                        const v8::Local<v8::Value> &value);
+
+  v8::Local<v8::Value> GetFromPersistent(const char *key) const;
+
+  v8::Local<v8::Value> GetFromPersistent(const v8::Local<v8::String> &key) const;
+
+  v8::Local<v8::Value> GetFromPersistent(uint32_t index) const;
+
+  virtual void Execute() = 0;
+
+  uv_work_t request;
+
+  virtual void Destroy();
+
+ protected:
+  Persistent<v8::Object> persistentHandle;
+
+  Callback *callback;
+
+  virtual void HandleOKCallback();
+
+  virtual void HandleErrorCallback();
+
+  void SetErrorMessage(const char *msg);
+
+  const char* ErrorMessage();
+};
+```
+
+<a name="api_nan_async_progress_worker"></a>
+### Nan::AsyncProgressWorkerBase &amp; Nan::AsyncProgressWorker
+
+`Nan::AsyncProgressWorkerBase` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+Previously the definiton of `Nan::AsyncProgressWorker` only allowed sending `const char` data. Now extending `Nan::AsyncProgressWorker` will yield an instance of the implicit `Nan::AsyncProgressWorkerBase` template with type `<char>` for compatibility.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressWorkerBase<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressWorker(Callback *callback_);
+
+  virtual ~AsyncProgressWorker();
+
+  void WorkProgress();
+
+  class ExecutionProgress {
+   public:
+    void Signal() const;
+    void Send(const T* data, size_t count) const;
+  };
+
+  virtual void Execute(const ExecutionProgress& progress) = 0;
+
+  virtual void HandleProgressCallback(const T *data, size_t count) = 0;
+
+  virtual void Destroy();
+};
+
+typedef AsyncProgressWorkerBase<T> AsyncProgressWorker;
+```
+
+<a name="api_nan_async_queue_worker"></a>
+### Nan::AsyncQueueWorker
+
+`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.
+
+Definition:
+
+```c++
+void AsyncQueueWorker(AsyncWorker *);
+```

+## Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+ - <a href="#api_nan_new_buffer"><b><code>Nan::NewBuffer()</code></b></a>
+ - <a href="#api_nan_copy_buffer"><b><code>Nan::CopyBuffer()</code></b></a>
+ - <a href="#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
+
+<a name="api_nan_new_buffer"></a>
+### Nan::NewBuffer()
+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.
+
+Signature:
+
+```c++
+Nan::MaybeLocal<v8::Object> Nan::NewBuffer(uint32_t size)
+Nan::MaybeLocal<v8::Object> Nan::NewBuffer(char* data, uint32_t size)
+Nan::MaybeLocal<v8::Object> Nan::NewBuffer(char *data,
+                                           size_t length,

+```
+
+
+<a name="api_nan_copy_buffer"></a>
+### Nan::CopyBuffer()
+
+Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
+
+Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.
+
+Signature:
+
+```c++
+Nan::MaybeLocal<v8::Object> Nan::CopyBuffer(const char *data, uint32_t size)
+```
+
+
+<a name="api_nan_free_callback"></a>
+### Nan::FreeCallback()
+
+A free callback that can be provided to [`Nan::NewBuffer()`](#api_nan_new_buffer).
+The supplied callback will be invoked when the `Buffer` undergoes garbage collection.
+
+Signature:
+
+```c++
+typedef void (*FreeCallback)(char *data, void *hint);
+```

node_modules/onoff/node_modules/epoll/node_modules/nan/doc/callback.md

+## Nan::Callback
+
+`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
+
+ - <a href="#api_nan_callback"><b><code>Nan::Callback</code></b></a>

+  Callback();
+
+  explicit Callback(const v8::Local<v8::Function> &fn);
+
+  ~Callback();

node_modules/onoff/node_modules/epoll/node_modules/nan/doc/converters.md

+## Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
+
+ - <a href="#api_nan_to"><b><code>Nan::To()</code></b></a>
+
+<a name="api_nan_to"></a>
+### Nan::To()
+
+Converts a `v8::Local<v8::Value>` to a different subtype of `v8::Value` or to a native data type. Returns a `Nan::MaybeLocal<>` or a `Nan::Maybe<>` accordingly.
+
+See [maybe_types.md](./maybe_types.md) for more information on `Nan::Maybe` types.

+## New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

+
+
+<a name="api_nan_new"></a>
+### Nan::New()
+
+`Nan::New()` should be used to instantiate new JavaScript objects.
+
+Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/io.js-3.0/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
+
+Signatures:
+
+Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
+
+Empty objects:
+
+```c++
+Nan::New<T>();
+```
+
+Generic single and multiple-argument:
+
+```c++
+Nan::New<T>(A0 arg0);
+Nan::New<T>(A0 arg0, A1 arg1);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
+```
+
+For creating `v8::FunctionTemplate` and `v8::Function` objects:
+
+_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
+
+```c++
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>());
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>(),
+            A2 a2 = A2());
+```
+
+Native number types:
+
+```c++
+v8::Local<v8::Boolean> Nan::New<T>(bool value);
+v8::Local<v8::Int32> Nan::New<T>(int32_t value);
+v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
+v8::Local<v8::Number> Nan::New<T>(double value);
+```
+
+String types:
+
+```c++
+Nan::MaybeLocal<v8::String> Nan::New<T>(std::string const& value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value, int length);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value, int length);
+```
+
+Specialized types:
+
+```c++
+v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
+v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
+v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
+```
+
+Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/io.js-3.0/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

+
+### This vs. Holder
+
+When calling `Unwrap`, it is important that the argument is indeed some JavaScript object which got wrapped by a `Wrap` call for this class or any derived class.
+The `Signature` installed by [`Nan::SetPrototypeMethod()`](methods.md#api_nan_set_prototype_method) does ensure that `info.Holder()` is just such an instance.
+In Node 0.12 and later, `info.This()` will also be of such a type, since otherwise the invocation will get rejected.
+However, in Node 0.10 and before it was possible to invoke a method on a JavaScript object which just had the extension type in its prototype chain.
+In such a situation, calling `Unwrap` on `info.This()` will likely lead to a failed assertion causing a crash, but could lead to even more serious corruption.
+
+On the other hand, calling `Unwrap` in an [accessor](methods.md#api_nan_set_accessor) should not use `Holder()` if the accessor is defined on the prototype.
+So either define your accessors on the instance template,
+or use `This()` after verifying that it is indeed a valid object.
+
+### Examples
+
+#### Basic
+
+```c++
+class MyObject : public Nan::ObjectWrap {
+ public:
+  static NAN_MODULE_INIT(Init) {
+    v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);

+    tpl->InstanceTemplate()->SetInternalFieldCount(1);
+
+    Nan::SetPrototypeMethod(tpl, "getHandle", GetHandle);
+    Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
+
+    constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+    Nan::Set(target, Nan::New("MyObject").ToLocalChecked(),
+      Nan::GetFunction(tpl).ToLocalChecked());
+  }
+
+ private:
+  explicit MyObject(double value = 0) : value_(value) {}
+  ~MyObject() {}
+
+  static NAN_METHOD(New) {
+    if (info.IsConstructCall()) {
+      double value = info[0]->IsUndefined() ? 0 : Nan::To<double>(info[0]).FromJust();
+      MyObject *obj = new MyObject(value);
+      obj->Wrap(info.This());

+    MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());
+    info.GetReturnValue().Set(obj->value_);
+  }
+
+  static inline Nan::Persistent<v8::Function> & constructor() {
+    static Nan::Persistent<v8::Function> my_constructor;
+    return my_constructor;
+  }
+
+  double value_;
+};
+
+NODE_MODULE(objectwrapper, MyObject::Init)

node_modules/onoff/node_modules/epoll/node_modules/nan/doc/scopes.md

+## Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+<a name="api_nan_handle_scope"></a>
+### Nan::HandleScope
+
+A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/io.js-3.0/d3/d95/classv8_1_1_handle_scope.html).
+
+Definition:
+
+```c++
+class Nan::HandleScope {
+ public:
+  Nan::HandleScope();
+  static int NumberOfHandles();
+};
+```
+
+Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
+
+Example:
+
+```c++
+// new object is created, it needs a new scope:
+void Pointless() {
+  Nan::HandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+
+// JavaScript-accessible method already has a HandleScope
+NAN_METHOD(Pointless2) {
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+```
+
+<a name="api_nan_escapable_handle_scope"></a>
+### Nan::EscapableHandleScope
+
+Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
+
+Definition:
+
+```c++
+class Nan::EscapableHandleScope {
+ public:
+  Nan::EscapableHandleScope();
+  static int NumberOfHandles();
+  template<typename T> v8::Local<T> Escape(v8::Local<T> value);
+}
+```
+
+Use `Escape(value)` to return the object.
+
+Example:
+
+```c++
+v8::Local<v8::Object> EmptyObj() {
+  Nan::EscapableHandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+  return scope.Escape(obj);
+}
+```

+
+
+<a name="api_nan_run_script"></a>
