+
+> Split a string on a character except when the character is escaped.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save split-string
+```
+
+<!-- section: Why use this? -->
+
+<details>
+<summary><strong>Why use this?</strong></summary>
+
+<br>
+
+Although it's easy to split on a string:
+
+```js
+console.log('a.b.c'.split('.'));
+//=> ['a', 'b', 'c']
+```
+
+It's more challenging to split a string whilst respecting escaped or quoted characters.
+
+**Bad**
+
+```js
+console.log('a\\.b.c'.split('.'));
+//=> ['a\\', 'b', 'c']
+
+console.log('"a.b.c".d'.split('.'));
+//=> ['"a', 'b', 'c"', 'd']
+```
+
+**Good**
+
+```js
+var split = require('split-string');
+console.log(split('a\\.b.c'));
+//=> ['a.b', 'c']
+
+console.log(split('"a.b.c".d'));
+//=> ['a.b.c', 'd']
+```
+
+See the [options](#options) to learn how to choose the separator or retain quotes or escaping.
+
+<br>
+
+</details>
+
+## Usage
+
+```js
+var split = require('split-string');
+
+split('a.b.c');
+//=> ['a', 'b', 'c']
+
+// respects escaped characters
+split('a.b.c\\.d');
+//=> ['a', 'b', 'c.d']
+
+// respects double-quoted strings
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+```
+
+**Brackets**
+
+Also respects brackets [unless disabled](#optionsbrackets):
+
+```js
+split('a (b c d) e', ' ');
+//=> ['a', '(b c d)', 'e']
+```
+
+## Options
+
+### options.brackets
+
+**Type**: `object|boolean`
+
+**Default**: `undefined`
+
+**Description**
+
+If enabled, split-string will not split inside brackets. The following brackets types are supported when `options.brackets` is `true`,
+
+```js
+{
+  '<': '>',
+  '(': ')',
+  '[': ']',
+  '{': '}'
+}
+```
+
+Or, if object of brackets must be passed, each property on the object must be a bracket type, where the property key is the opening delimiter and property value is the closing delimiter.
+
+**Examples**
+
+```js
+// no bracket support by default
+split('a.{b.c}');
+//=> [ 'a', '{b', 'c}' ]
+
+// support all basic bracket types: "<>{}[]()"
+split('a.{b.c}', {brackets: true});
+//=> [ 'a', '{b.c}' ]
+
+// also supports nested brackets 
+split('a.{b.{c.d}.e}.f', {brackets: true});
+//=> [ 'a', '{b.{c.d}.e}', 'f' ]
+
+// support only the specified brackets
+split('[a.b].(c.d)', {brackets: {'[': ']'}});
+//=> [ '[a.b]', '(c', 'd)' ]
+```
+
+### options.sep
+
+**Type**: `string`
+
+**Default**: `.`
+
+The separator/character to split on.
+
+**Example**
+
+```js
+split('a.b,c', {sep: ','});
+//=> ['a.b', 'c']
+
+// you can also pass the separator as string as the last argument
+split('a.b,c', ',');
+//=> ['a.b', 'c']
+```
+
+### options.keepEscaping
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep backslashes in the result.
+
+**Example**
+
+```js
+split('a.b\\.c');
+//=> ['a', 'b.c']
+
+split('a.b.\\c', {keepEscaping: true});
+//=> ['a', 'b\.c']
+```
+
+### options.keepQuotes
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep single- or double-quotes in the result.
+
+**Example**
+
+```js
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a."b.c.d".e', {keepQuotes: true});
+//=> ['a', '"b.c.d"', 'e']
+
+split('a.\'b.c.d\'.e', {keepQuotes: true});
+//=> ['a', '\'b.c.d\'', 'e']
+```
+
+### options.keepDoubleQuotes
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep double-quotes in the result.
+
+**Example**
+
+```js
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a."b.c.d".e', {keepDoubleQuotes: true});
+//=> ['a', '"b.c.d"', 'e']
+```
+
+### options.keepSingleQuotes
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep single-quotes in the result.
+
+**Example**
+
+```js
+split('a.\'b.c.d\'.e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a.\'b.c.d\'.e', {keepSingleQuotes: true});
+//=> ['a', '\'b.c.d\'', 'e']
+```
+
+## Customizer
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Pass a function as the last argument to customize how tokens are added to the array.
+
+**Example**
+
+```js
+var arr = split('a.b', function(tok) {
+  if (tok.arr[tok.arr.length - 1] === 'a') {
+    tok.split = false;
+  }
+});
+console.log(arr);
+//=> ['a.b']
+```
+
+**Properties**
+
+The `tok` object has the following properties:
+
+* `tok.val` (string) The current value about to be pushed onto the result array
+* `tok.idx` (number) the current index in the string
+* `tok.str` (string) the entire string
+* `tok.arr` (array) the result array
+
+## Release history
+
+### v3.0.0 - 2017-06-17
+
+**Added**
+
+* adds support for brackets

+
+> Returns true if a value is a plain object, array or function.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extendable
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* array
+* plain object
+* function
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is a plain object, function or array
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Release history
+
+### v1.0.0 - 2017/07/20
+
+**Breaking changes**
+
+* No longer considers date, regex or error objects to be extendable
