# @babel/plugin-transform-unicode-property-regex

Compile [Unicode property escapes](https://github.com/mathiasbynens/regexpu-core/blob/master/property-escapes.md) (`\p{…}` and `\P{…}`) in Unicode regular expressions to ES5 or ES6 that works in today’s environments.

**Note:** the Unicode property escape syntax is non-standard and may or may not reflect what eventually gets specified.

[Here’s an online demo.](https://mothereff.in/regexpu#input=var+regex+%3D+/%5Cp%7BScript_Extensions%3DGreek%7D/u%3B&unicodePropertyEscape=1)

## Installation

```sh
$ npm install @babel/plugin-transform-unicode-property-regex
```

## Usage

### Via `.babelrc` (recommended)

`.babelrc`

```json
{
"plugins": ["transform-unicode-property-regex"]
}
```

### Via CLI

```sh
$ babel --plugins transform-unicode-property-regex script.js
```

### Via Node.js API

```js
require('@babel/core').transform(code, {
'plugins': ['transform-unicode-property-regex']
});
```

To transpile to ES6/ES2015:

```js
require('@babel/core').transform(code, {
'plugins': [
['transform-unicode-property-regex', { 'useUnicodeFlag': true }]
]
});
```
