> 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`"):
|
|
|
|
```js
|
|
var re = not('foo');
|
|
console.log(re.test('foo', {contains: true})); //=> false
|
|
console.log(re.test('bar', {contains: true})); //=> true
|
|
console.log(re.test('foobar', {contains: true})); //=> false
|
|
console.log(re.test('barfoo', {contains: true})); //=> false
|
|
```
