> Create a javascript regular expression for matching everything except for the given string.
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 regex-not
```
## Usage
```js
var not = require('regex-not');
```
The main export is a function that takes a string an options object.
```js
not(string[, options]);
```
**Example**
```js
var not = require('regex-not');
console.log(not('foo'));
//=> /^(?:(?!^(?:foo)$).)+$/
```
**Strict matching**
By default, the returned regex is for strictly (not) matching the exact given pattern (in other words, "match this string if it does NOT _exactly equal_ `foo`"):
```js
var re = not('foo');
console.log(re.test('foo')); //=> false
console.log(re.test('bar')); //=> true
console.log(re.test('foobar')); //=> true
console.log(re.test('barfoo')); //=> true
```
### .create
Returns a string to allow you to create your own regex:
```js
console.log(not.create('foo'));
//=> '(?:(?!^(?:foo)$).)+'
```
### Options
**options.contains**
You can relax strict matching by setting `options.contains` to true (in other words, "match this string if it does NOT _contain_ `foo`"):
