-# regexpu-core [![Build status](https://travis-ci.org/mathiasbynens/regexpu-core.svg?branch=master)](https://travis-ci.org/mathiasbynens/regexpu-core) [![Code coverage status](http://img.shields.io/coveralls/mathiasbynens/regexpu-core/master.svg)](https://coveralls.io/r/mathiasbynens/regexpu-core) [![Dependency status](https://gemnasium.com/mathiasbynens/regexpu-core.svg)](https://gemnasium.com/mathiasbynens/regexpu-core)
-
-_regexpu_ is a source code transpiler that enables the use of ES6 Unicode regular expressions in JavaScript-of-today (ES5).
-
-_regexpu-core_ contains _regexpu_’s core functionality, i.e. `rewritePattern(pattern, flag)`, which enables rewriting regular expressions that make use of [the ES6 `u` flag](https://mathiasbynens.be/notes/es6-unicode-regex) into equivalent ES5-compatible regular expression patterns.
-
-## Installation
-
-To use _regexpu-core_ programmatically, install it as a dependency via [npm](https://www.npmjs.com/):
-
-```bash
-npm install regexpu-core --save-dev
-```
-
-Then, `require` it:
-
-```js
-const rewritePattern = require('regexpu-core');
-```
-
-## API
-
-This module exports a single function named `rewritePattern`.
-
-### `rewritePattern(pattern, flags)`
-
-This function takes a string that represents a regular expression pattern as well as a string representing its flags, and returns an ES5-compatible version of the pattern.
-
-```js
-rewritePattern('foo.bar', 'u');
-// → 'foo(?:[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uD7FF\\uDC00-\\uFFFF]|[\\uD800-\\uDBFF][\\uDC00-\\uDFFF]|[\\uD800-\\uDBFF])bar'
-
-rewritePattern('[\\u{1D306}-\\u{1D308}a-z]', 'u');
-// → '(?:[a-z]|\\uD834[\\uDF06-\\uDF08])'
-
-rewritePattern('[\\u{1D306}-\\u{1D308}a-z]', 'ui');
-// → '(?:[a-z\\u017F\\u212A]|\\uD834[\\uDF06-\\uDF08])'
-```
-
-_regexpu-core_ can rewrite non-ES6 regular expressions too, which is useful to demonstrate how their behavior changes once the `u` and `i` flags are added:
-
-```js
-// In ES5, the dot operator only matches BMP symbols:
-rewritePattern('foo.bar');
-// → 'foo(?:[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uFFFF])bar'
-
-// But with the ES6 `u` flag, it matches astral symbols too:
-rewritePattern('foo.bar', 'u');
-// → 'foo(?:[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uD7FF\\uDC00-\\uFFFF]|[\\uD800-\\uDBFF][\\uDC00-\\uDFFF]|[\\uD800-\\uDBFF])bar'
-```
-
-`rewritePattern` uses [regjsgen](https://github.com/d10/regjsgen), [regjsparser](https://github.com/jviereck/regjsparser), and [regenerate](https://github.com/mathiasbynens/regenerate) as internal dependencies.
