-<summary>Crossplatform commands</summary>
-	
-	```
-	'variables': {
-		'rm'    : '<!(node -e "require(\'addon-tools-raub\').rm()")',
-		'cp'    : '<!(node -e "require(\'addon-tools-raub\').cp()")',
-		'mkdir' : '<!(node -e "require(\'addon-tools-raub\').mkdir()")',
-	},
-	```
-	
-	On both Windows and Unix those are the console commands for various
-	file system operations. No need for GYP conditions, yay!
-	
-</details>
-
-
-<details>
-
-<summary>Addon binary directory</summary>
-	
-	```
-	'variables': {
-		'binary' : '<!(node -e "require(\'addon-tools-raub\').bin()")',
-	},
-	```
-	
-	In some cases, you'd like to have your addon installed for multiple architectures
-	simultaneously. For example, when using NVM to fluently switch environments.
-	Because the target directory is different for each arch, you only have to do
-	`npm rebuild` after the first switch.
-	
-</details>
-
-
-<details>
-
-<summary>Include directories</summary>
-	
-	```
-		'include_dirs': [
-			'<!@(node -e "require(\'addon-tools-raub\').include()")',
-		],
-	```
-	
-	Those are the directory paths to C++ include files for Addon Tools and Nan
-	(which is preinstalled with Addon Tools)
-	
-</details>
-
-
-<details>
-
-<summary>Remove intermediates</summary>
-	
-	```
-		[ 'OS=="linux"', { 'action' : [
-			'<(rm)',
-			'<(module_root_dir)/build/Release/obj.target/addon/cpp/addon.o',
-			'<(module_root_dir)/build/Release/addon.node'
-		] } ],
-		[ 'OS=="mac"', { 'action' : [
-			'<(rm)',
-			'<(module_root_dir)/build/Release/obj.target/addon/cpp/addon.o',
-			'<(module_root_dir)/build/Release/addon.node'
-		] } ],
-		[ 'OS=="win"', { 'action' : [
-			'<(rm)',
-			'<(module_root_dir)/build/Release/addon.*',
-			'<(module_root_dir)/build/Release/obj/addon/*.*'
-		] } ],
-	```
-	
-	Build-files can be removed in a separate build-step with `<(rm)`. Those are
-	usually PDB and OBJ files, which are rather big. However, in case of a hardcore
-	debug session you might want to comment this out.
-	
-</details>
-
-
-### Binary dependency package
-
-If you design a module with binary dependencies for several platforms, **Addon Tools**
-would encourage you to abide by the following rules:
-
-* Your binary directories are:
-	
-	* bin-win32
-	* bin-win64
-	* bin-linux32
-	* bin-linux64
-	* bin-mac64
-	
-* The following piece of code in your `index.js` without changes. Method `paths()`
-is described [here](#indexjs).
-	
-	```
-	module.exports = require('addon-tools-raub').paths(__dirname);
-	```
-	
-* Your whole **binding.gyp**:
-	
-	<details>
-	
-	<summary>Show binding.gyp</summary>
-	
-	```
-	{
-		'variables': {
-			'rm'   : '<!(node -e "require(\'addon-tools-raub\').rm()")',
-			'rem'  : '<!(node -e "require(\'.\').rem()")',
-			'XALL%': 'false',
-		},
-		'targets': [
-			{
-				'target_name' : 'remove_extras',
-				'type'        : 'none',
-				'conditions'  : [['XALL=="false"', {'actions': [
-					{
-						'action_name' : 'Unnecessary binaries removed.',
-						'inputs'      : [],
-						'outputs'     : ['build'],
-						'action'      : ['<(rm)', '-rf', '<@(rem)'],
-					}
-				]}]],
-			}
-		]
-	}
-	```
-	
-	Notice the `XALL` variable here. If the package is installed with `npm i`, then
-	quite expectedly all but the required arch directories are removed. But with
-	`npm i --XALL` you can keep all the binaries. It might be useful when debugging
-	multiple archs and switching Node.js versions with
-	[NVM](https://github.com/creationix/nvm).
-	
-	</details>
-
-
-### Compiled addon
-
-It is easy to build a C++ addon with **Addon Tools**. To have a full picture, you
-can view the
-[official example](https://github.com/node-3d/addon-tools-raub/tree/master/examples/addon).
-
-The main file for an addon is **binding.gyp**. Here's a snippet with most of the features.
-
-<details>
-
-<summary>binding.gyp</summary>
-
-* Assume `EXT_LIB` is the name of an Addon Tools compliant binary dependency module.
-* Assume `MY_ADDON` is the name of this addon.
-* Assume C++ code goes to `cpp` directory.

 ## include/addon-tools.hpp
 
-There is a C++ header file, `addon-tools.hpp`, shipped with this package. It
+Macro shortcuts for C++ addons using **NAPI**.
-introduces several useful macros and utilities. Also it includes Nan automatically,
+See [docs inside the folder](/include).
-so that you can replace:
+
+Example of an addon method definition:
 
 ```
-// #include <v8.h> // already in node.h
+// hpp:
-// #include <node.h> // already in nan.h
+#include <addon-tools.hpp>
-#include <nan.h>
+DBG_EXPORT JS_METHOD(doSomething);
-```
+// cpp:
-
+DBG_EXPORT JS_METHOD(doSomething) { NAPI_ENV;
-with
+	LET_INT32_ARG(0, param0);
-
+	std::cout << "param0: " << param0 << std::endl;
-```
+	RET_UNDEFINED;
-#include <addon-tools.hpp> // or event-emitter.hpp
-```
-
-In gyp, the include directory should be set for your addon to know where to get it.
-As it was mentioned above, this can be done automatically. Also an actual path to the
-directory is exported from the module and is accessible like this:
-
-```
-require('addon-tools-raub').include() // implicit console.log()
-require('addon-tools-raub').includePath // just a string
-```
-
-Currently, there are following helpers in **addon-tools.hpp**:

-[Nan doc](https://github.com/nodejs/nan/blob/master/doc/methods.md#api_nan_method).
-So it is most likely to be used in parts of code called from C++ land.

-## Crossplatform commands
-
-Because of the differences between Windows and Unix command shells, often a whole
-lot of conditions have to be introduced in **binding.gyp** file. Now some of
-them can be easily omitted with the new crossplatform commands, supplied by this
-package.
-
-This comes especially handy together with GYP's executable list expansion. For
-example a list of files to be removed for cleaning. Or a list of unnecessary
-binaries to be removed upon installation of a binary-dependency package.
-
-
-### mkdir
-
-On Unix, it will be an actual system `mkdir`, whereas on Windows it will use the
-**mkdir.bat** file, located at the root of this package. This BAT file behaves
-as if it was a `mkdir -p ...` call. You can still pass `-p` switch, which is
-ignored. And the limitation is that you can not create a relative-path **-p**
-folder. This can possibly be bypassed by supplying `./-p` or something like this.
-
-
 ```
-'variables': {
+	'getBin', 'getPlatform', 'getInclude', 'getPaths',
-	'mkdir' : '<!(node -e "require(\'addon-tools-raub\').mkdir()")',
+	'install', 'cpbin', 'download', 'read', 'write', 'copy', 'exists',
-},
+	'mkdir', 'stat', 'isDir', 'isFile', 'dirUp', 'ensuredir', 'copysafe',
-...
+	'readdir', 'subdirs', 'subfiles', 'traverse', 'copyall',
-'action' : ['<(mkdir)', '-p', 'binary'],
+	'rmdir', 'rm', 'WritableBuffer', 'actionPack',
 ```
 
 
-### rm
+See the [TypeScript definitions](/index.d.ts) with comments.
 
-Disregard `del` and `rd` on Windows command line. Now the same command can
+
-be used on all platforms to remove single and multiple files and directories.
+### Example for an ADDON's **index.js**:
 
 ```
-'variables': {
+	const { getBin } = require('addon-tools-raub');
-	'rm'  : '<!(node -e "require(\'addon-tools-raub\').rm()")',
+	const core = require(`./${getBin()}/ADDON`); // uses the platform-specific ADDON.node
-	'rem' : '<!(node -e "require(\'.\').rem()")',
-},
-...
-'action' : ['<(rm)', '-rf', '<@(rem)'],
 ```
 
-### cp
 
-For Windows the `/y` flag was embedded.
+### Example for **binding.gyp**:
-
-```
-'variables': {
-	'cp'  : '<!(node -e "require(\'addon-tools-raub\').cp()")',
-},
-...
-'action' : ['<(cp)', 'a', 'b'],

-## Class EventEmitter
-
-A C++ implementation of [Events API](https://nodejs.org/api/events.html).
-
-> Note: This implementation has some minor deviations from the above standard.
-Specifically there is no static `EventEmitter.defaultMaxListeners` property.
-However the dynamic one persists and is infinite (`0`) by default.
-
-Also
-[EventTarget](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget)
-is implemented. Not in full detail, but should be fine for callers.
-
-An example can be found in **examples/node-addon** directory.
-There is `Example` class, implemented in **cpp/example.cpp**, that inherits
-EventEmitter behavior and is exported to JS.
-
-For the C++ side `EventEmitter` has following public methods:
-
-* `void emit(const std::string &name, int argc = 0, v8::Local<v8::Value> *argv = NULL)` -
-emits an event with the given `name` and, optionally, some additional arguments where
-`argc` is the number of arguments and `argv` is a pointer to the arguments array.
-
-* `void on(const std::string &name, V8_VAR_FUNC cb)` -
-subscribes `cb` to receive `name` events from this emitter, basically
-`emitter.on(name, cb)`.
-
-* `void destroy()` - destroys the object, i.e. deactivates it and frees
-resources. This is what also called inside
-`~EventEmitter()`, but only the first call is effective anyway.
-
-
-Be sure to add the include directory in **binding.gyp**:
 
 ```
 	'include_dirs': [
-		'<!@(node -e "require(\'addon-tools-raub\').include()")',
+		'<!@(node -p "require(\'addon-tools-raub\').getInclude()")',
 	],
 ```
 
-Then include the **event-emitter.hpp**, it also includes **addon-tools.hpp**.
+> NOTE: the optional `node-addon-api` dependency is used by the `getInclude()` helper. If not found,
-Inherit from `EventEmitter`, it already inherits from `Nan::ObjectWrap`:
+	the **napi.h** include path won't be a part of the returned string.
+
+
+### Example of `cpbin` in **package.json :: scripts**:
 
 ```
-#include <event-emitter.hpp>
+	"build": "cd src && node-gyp rebuild -j max --silent && node -e \"require('addon-tools-raub').cpbin('segfault')\" && cd ..",
-
+	"build-only": "cd src && node-gyp build -j max --silent && node -e \"require('addon-tools-raub').cpbin('segfault')\" && cd ..",
-class Example : public EventEmitter {
-	...
-}
 ```
-
-> Note: Do not forget to call `EventEmitter::init()` once, in the module `init()`.
-
-
-<details>
-
-<summary>V8 Inheritance</summary>
-
-Now that everything is in place, consider providing **V8** with JS inheritance info:
-
-```
-void Example::init(Handle<Object> target) {
-	
-	Local<FunctionTemplate> proto = Nan::New<FunctionTemplate>(newCtor);
-	
-	// -------------------------- HERE!
-	// class Example extends EventEmitter
-	Local<FunctionTemplate> parent = Nan::New(EventEmitter::_prototype);
-	proto->Inherit(parent);
-	// --------------------------
-	
-	proto->InstanceTemplate()->SetInternalFieldCount(1);
-	proto->SetClassName(JS_STR("Example"));
-	
-	Local<Function> ctor = Nan::GetFunction(proto).ToLocalChecked();
-	
-	_constructor.Reset(ctor);
-	
-	Nan::Set(target, JS_STR("Example"), ctor);
-

-## Function consoleLog
-
-In C++ addons, the use of **iostream** is discouraged because **Node.js** has its own
-perspective on **stdout** behavior.
-At first it may look as if `cout << "msg" << endl;` works nice, but it doesn't.
-After a while, it just ceases on a midword, and you end up thinking something has
-broken really hard in your addon.
-
-To overcome this, we can use some V8 `eval` magic to make a real `console.log`
-call from C++ land. And this is where `consoleLog` comes into play.
-
-* `inline void consoleLog(int argc, V8_VAR_VAL *argv)` - a generic logger,
-receives any set of arguments.
-
-* `inline void consoleLog(const std::string &message)` - an alias to log a single
-string.
-
-> Note: Don't do it in GC-accessible code: sometimes it works, sometimes it crashes.

+# include/addon-tools.hpp
+
+There is a C++ header file, `addon-tools.hpp`, shipped with this package. It
+introduces several useful macros and utilities. Also it includes **NAPI**
+implicitly, so you can replace:
+
+```
+#include <napi.h>
+```
+with
+```
+#include <addon-tools.hpp>
+```
+
+In **GYP**, the include directory should be set for your addon.
+An actual path to the directory is exported from the module
+and is accessible with:
+```
+require('addon-tools-raub').getInclude() // a string
+```
+
+For more examples, see [code snippets here](snippets.md).
+
+
+### ES5 Classes
+
+The standard class-defining (i.e. exporting a JS class from the C++ side) tools
+from **NAPI** are a bit repetitive and excessive. So instead, Addon Tools
+comes with a set of helpers for old-school class definition.
+Think of it as ES5 classes. Just a function, spawning instances that have their
+constructor and prototype set accordingly. Such classes may be further extended
+and/or manipulated from JS-land. See the [class-wrapping doc here](class-wrapping.md).
+
+
+### Method Helpers
+
+Usually all the helpers work within the context of a method. In this case we
+have `Napi::CallbackInfo info` passed as an argument. And we can return `undefined`
+in case a problem has occured. So most of these macros are only usable
+within `Napi::Value`-returning functions.
+
+```
+#define NAPI_ENV Napi::Env env = info.Env();
+#define NAPI_HS Napi::HandleScope scope(env);
+```
+
+Other global helpers:
+* `DBG_EXPORT`- set symbol visibility (mainly for callstack traces). On Windows, that is
+	equal to exporting a symbol: `__declspec(dllexport)`. On Unix it does nothing.
+
+<details>
+
+<summary><b>Return value</b></summary>
+
+* `RET_VALUE(VAL)`- return a given Napi::Value.
+* `RET_UNDEFINED`- return `undefined`.
+* `RET_NULL` - return `null`.
+* `RET_STR(VAL)` - return `Napi::String`, expected `VAL` is `const char *`.
+* `RET_NUM(VAL)` - return `Napi::Number`, expected `VAL` is of numeric type.
+* `RET_EXT(VAL)` - return `Napi::External`, expected `VAL` is a pointer.
+* `RET_BOOL(VAL)` - return `Napi::Boolean`, expected `VAL` is convertible to bool.
+* `RET_ARRAY_STR(VAL)` - return `Napi::Array`, expected `VAL` is `std::vector<std::string>`.
+
+</details>
+
+
+
+<details>
+
+<summary><b>New JS value</b></summary>
+
+* `JS_UNDEFINED` - an `undefined` value.
+* `JS_NULL` - a `null` value.
+* `JS_STR(VAL)` - create a `Napi::String`, expected `VAL` is `const char *`.
+* `JS_NUM(VAL)` - create a `Napi::Number`, expected `VAL` is of numeric type.
+* `JS_EXT(VAL)` - create a `Napi::External`, expected `VAL` is a pointer.
+* `JS_BOOL(VAL)` - create a `Napi::Boolean`, expected `VAL` is convertible to bool.
+* `JS_OBJECT` - a new empty `Object` instance.
+* `JS_ARRAY` - a new empty `Array` instance.
+
+</details>
+
+
+<details>
+
+<summary><b>Method check</b></summary>
+
+These checks throw JS `TypeError` if not passed. `T` is always used as a typename
+in error messages. `C` is a
+[Napi::Value](https://github.com/nodejs/node-addon-api/blob/master/doc/value.md)
+check method, like `IsObject()`. `I` is the index of argument as in `info[I]`,
+starting from `0`.
+
+* `REQ_ARGS(N)` - check if at least `N` arguments passed
+* `IS_ARG_EMPTY(I)` - check if argument `I` is `undefined` or `null`
+* `CHECK_REQ_ARG(I, C, T)` - check if argument `I` is approved by `C` check.
+* `CHECK_LET_ARG(I, C, T)` - check if argument `I` is approved by `C` check or empty.
+* `SETTER_CHECK(C, T)` - check if setter `value` is approved by `C` check.
+* `DES_CHECK` - for void-returning methods, check if the instance wasn't
+destroyed by `destroy()`.
+* `THIS_CHECK` - check if the instance wasn't
+destroyed by `destroy()`, and then fetch `env`.
+
+</details>
+
+
+<details>
+
+<summary><b>Method arguments</b></summary>
+
+Following macros convert JS arguments into C++ variables.
+Three types of argument retrieval are supported:
+* `REQ_` - 2 params, requires an argument to have a value
+* `USE_` - 3 params, allows the argument to be empty and have a default
+* `LET_` - 2 params, is `USE_` with a preset zero-default.
+* `SOFT_` - 2 params, is `LET_` without type and arity checks.
+
+What it does, basically:
+```
+// REQ_DOUBLE_ARG(0, x)
+double x = info[0].ToNumber().DoubleValue();
+
+// USE_DOUBLE_ARG(0, x, 5.7)
+double x = IS_ARG_EMPTY(0) ? 5.7 : info[0].ToNumber().DoubleValue();
+
+// LET_DOUBLE_ARG(0, x)
+double x = IS_ARG_EMPTY(0) ? 0.0 : info[0].ToNumber().DoubleValue();
+```
+
+That extrapolates well to all the helpers below:

+* `T *getArrayData(value, num = NULL)` - extracts TypedArray data of any type from
+the given JS value. Does not accept `Array`. Checks with `IsArrayBuffer()`.
+Returns `nullptr` for empty JS values. For unacceptable values throws TypeError.
+
+* `T *getBufferData(value, num = NULL)` - extracts Buffer data from
+the given JS value. Checks with `IsBuffer()`.
+Returns `nullptr` for empty JS values. For unacceptable values throws TypeError.
+
+* `void *getData(value)` - if `value` is a `TypedArray|Buffer`,
+calls `getArrayData` or `getArrayData` on it. Otherwise, if 
+`value.data` is a `TypedArray|Buffer`,
+calls `getArrayData` or `getArrayData` on it.
+Returns `nullptr` in other cases.

+# Es5 class wrapping
+
+This wrapping implementation diverges from standard ES6 style wrapping.
+It also uses composition rather than inheritance, so it is easily pluggable.
+
+* For **NAPI** addons, `super()` can be called from C++ side.
+* Constructor is callable with `ClassName.call(obj, ...args)`.
+* Multiple C++ objects can be attached to a single JS object
+if it is necessary in an inheritance scenario.
+* On JS side `util.inherits`
+[is used](https://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor),
+and on C++ side there is `inheritEs5` function.
+
+
+## Class Declaration
+
+```
+class ClassName {
+DECLARE_ES5_CLASS(ClassName, JSClassName);
+	
+public:
+	static void init(Napi::Env env, Napi::Object exports);
+	explicit ClassName(const Napi::CallbackInfo& info);
+	~ClassName();
+	
+	void _destroy();
+	
+ private:
+	JS_DECLARE_GETTER(ClassName, isDestroyed);
+	
+	JS_DECLARE_METHOD(ClassName, ClassName, destroy);
+	
+	bool _isDestroyed;
+};
+```
+
+* `DECLARE_ES5_CLASS` - adds utility declarations, the first argument
+must be this class name, and the second argument will become the
+name (arbitrary) of this function (constructor) in JS.
+* `init` - can be used to initialize this class and export it.
+* `JS_DECLARE_METHOD` - declares a method, the first argument is this class,
+the second is the name of the method to be created.
+* `JS_DECLARE_GETTER` - declares a getter, the first argument is this class,
+the second is the name of the getter to be created.
+* `JS_DECLARE_SETTER` - declares a setter, the first argument is this class,
+the second is the name of the setter to be created.
+
+
+## Class Implementation
+
+```
+IMPLEMENT_ES5_CLASS(ClassName);
+
+// Fill the properties and export the class
+void ClassName::init(Napi::Env env, Napi::Object exports) {
+	Napi::Function ctor = wrap(env);
+	JS_ASSIGN_METHOD(destroy);
+	JS_ASSIGN_GETTER(isDestroyed);
+	// ...
+	exports.Set("JSClassName", ctor);
+}
+
+ClassName::ClassName(const Napi::CallbackInfo &info) { NAPI_ENV;
+	super(info);
+	_isDestroyed = false;
+	
+	// ...
+}
+
+ClassName::~ClassName() {
+	_destroy();
+}
+
+void ClassName::_destroy() { DES_CHECK;
+	// ...
+	_isDestroyed = true;
+}
+
+
+JS_IMPLEMENT_METHOD(ClassName, destroy) { THIS_CHECK;
+	emit("destroy");
+	_destroy();
+	RET_UNDEFINED;
+}
+
+
+JS_IMPLEMENT_GETTER(ClassName, isDestroyed) { THIS_CHECK;
+	RET_BOOL(_isDestroyed);
+}
+
+```
+
+* `IMPLEMENT_ES5_CLASS` - implements some utility functions for class wrapping.
+* `JS_ASSIGN_METHOD` - in `init()`, assigns the given method to this class.
+* `JS_ASSIGN_GETTER` - in `init()`, assigns the given getter to this class.
+* `JS_ASSIGN_SETTER` - in `init()`, assigns both getter and setter to this class.
+It also takes only one argument because both have the same name.
+* `JS_IMPLEMENT_METHOD` - implements a method, the first argument is this class,
+the second is the name of the method being implemented.
+* `JS_IMPLEMENT_GETTER` - implements a getter, the first argument is this class,
+the second is the name of the getter being implemented.
+* `JS_IMPLEMENT_SETTER` - implements a setter, the first argument is this class,
+the second is the name of the setter being implemented.

+# Snippets
+
+## C++ Addon building
+
+### Binary distribution
+
+In **package.json** use the `"postinstall"` script to download the libraries.
+For example the following structure might work. Note that **Addon Tools** will
+append any given URL with `/${getPlatform()}.gz`
+
+In **package.json**:
+
+```
+	"scripts": {
+		"postinstall": "node install",
+	},
+	"dependencies": {
+		"addon-tools-raub": "^7.0.0",
+	},
+	"devDependencies": {
+		"node-addon-api": "^5.0.0"
+	}
+```
+
+Create the **install.js** file, see `install` in [index.d.ts](/index.d.ts).
+**Addon Tools** will unpack (using **tar**) the downloaded file into the platform binary
+directory. E.g. on Windows it will be **bin-windows**.
+
+* For a dependency package:
+	
+	Place the following piece of code into the `index.js` without changes.
+	
+	```
+	module.exports = require('addon-tools-raub').getPaths(__dirname);
+	```
+	
+* For a compiled addon:
+	
+	Require the `ADDON.node` in your **index.js** from the platform-specific directory.
+	```
+	const { getBin } = require('addon-tools-raub');
+	const core = require(`./${getBin()}/ADDON`);
+	```
+
+
+Publishing binaries is done by attaching a GZIPped platform folder to a GitHub
+release. Zip file must NOT contain platform folder as a subfolder, but rather
+contain the final binaries. The tag of the release should be the same as in
+**install.js**.
+
+> NOTE: You can publish your binaries to anywhere, not necessarily GitHub.
+Just tweak **YOUR install.js** script as appropriate. The only limitation
+from **Addon Tools** is that it should be a GZIPped set of files/folders.
+
+
+### GYP Variables
+
+```
+	'variables': {
+		'bin': '<!(node -p "require(\'addon-tools-raub\').getBin()")',
+		'DEPS_include': '<!(node -p "require(\'DEPS\').getInclude()")',
+		'DEPS_bin': '<!(node -p "require(\'DEPS\').getBin()")',
+	},
+```
+
+* `bin` - the name of this platform's binary directory, e.g. *bin-linux*.
+* `DEPS_include` - the include folder for some dependency package.
+* `DEPS_bin` - the binary folder for some dependency package.
+
+
+
+### Include directories
+
+```
+	'include_dirs' : [
+		'<!@(node -p "require(\'addon-tools-raub\').getInclude()")',
+		'<(DEPS_include)',
+	],
+```
+
+See example of a working [**binding.gyp** here](/test-addon/binding.gyp)
