-# regexpu-core [![Build status](https://github.com/mathiasbynens/regexpu-core/workflows/run-checks/badge.svg)](https://github.com/mathiasbynens/regexpu-core/actions?query=workflow%3Arun-checks) [![regexpu-core on npm](https://img.shields.io/npm/v/regexpu-core)](https://www.npmjs.com/package/regexpu-core)
-
-_regexpu_ is a source code transpiler that enables the use of ES2015 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 ES2015 `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
-```
-
-Then, `require` it:
-
-```js
-const rewritePattern = require('regexpu-core');
-```
-
-## API
-
-This module exports a single function named `rewritePattern`.
-
-### `rewritePattern(pattern, flags, options)`
-
-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 ES2015 `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'
-```
-
-The optional `options` argument recognizes the following properties:
-
-#### Stable regular expression features
-
-These options can be set to `false` or `'transform'`. When using `'transform'`, the corresponding features are compiled to older syntax that can run in older browsers. When using `false` (the default), they are not compiled and they can be relied upon to compile more modern features.
-
-- `unicodeFlag` - The `u` flag, enabling support for Unicode code point escapes in the form `\u{...}`.
-
-  ```js
-  rewritePattern('\\u{ab}', '', {
-    unicodeFlag: 'transform'
-  });
-  // → '\\u{ab}'
-
-  rewritePattern('\\u{ab}', 'u', {
-    unicodeFlag: 'transform'
-  });
-  // → '\\xAB'
-  ```
-
-- `dotAllFlag` - The [`s` (`dotAll`) flag](https://github.com/mathiasbynens/es-regexp-dotall-flag).
-
-  ```js
-  rewritePattern('.', '', {
-    dotAllFlag: 'transform'
-  });
-  // → '[\\0-\\t\\x0B\\f\\x0E-\\u2027\\u202A-\\uFFFF]'
-
-  rewritePattern('.', 's', {
-    dotAllFlag: 'transform'
-  });
-  // → '[\\0-\\uFFFF]'
-
-  rewritePattern('.', 'su', {
-    dotAllFlag: 'transform'
-  });
-  // → '(?:[\\0-\\uD7FF\\uE000-\\uFFFF]|[\\uD800-\\uDBFF][\\uDC00-\\uDFFF]|[\\uD800-\\uDBFF](?![\\uDC00-\\uDFFF])|(?:[^\\uD800-\\uDBFF]|^)[\\uDC00-\\uDFFF])'
-  ```
-
-- `unicodePropertyEscapes` - [Unicode property escapes](property-escapes.md).
-
-  By default they are compiled to Unicode code point escapes of the form `\u{...}`. If the `unicodeFlag` option is set to `'transform'` they often result in larger output, although there are cases (such as `\p{Lu}`) where it actually _decreases_ the output size.
-
-  ```js
-  rewritePattern('\\p{Script_Extensions=Anatolian_Hieroglyphs}', 'u', {
-    unicodePropertyEscapes: 'transform'
-  });
-  // → '[\\u{14400}-\\u{14646}]'
-
-  rewritePattern('\\p{Script_Extensions=Anatolian_Hieroglyphs}', 'u', {
-    unicodeFlag: 'transform',
-    unicodePropertyEscapes: 'transform'
-  });
-  // → '(?:\\uD811[\\uDC00-\\uDE46])'
-  ```
-
-- `namedGroups` - [Named capture groups](https://github.com/tc39/proposal-regexp-named-groups).
-
-  ```js
-  rewritePattern('(?<name>.)\\k<name>', '', {
-    namedGroups: 'transform'
-  });
-  // → '(.)\1'
-  ```
-
-#### Experimental regular expression features
-
-These options can be set to `false`, `'parse'` and `'transform'`. When using `'transform'`, the corresponding features are compiled to older syntax that can run in older browsers. When using `'parse'`, they are parsed and left as-is in the output pattern. When using `false` (the default), they result in a syntax error if used.
-
-Once these features become stable (when the proposals are accepted as part of ECMAScript), they will be parsed by default and thus `'parse'` will behave like `false`.
-
-- `unicodeSetsFlag` - [The `v` (`unicodeSets`) flag](https://github.com/tc39/proposal-regexp-set-notation)
-
-  ```js
-  rewritePattern('[\\p{Emoji}&&\\p{ASCII}]', 'u', {
-    unicodeSetsFlag: 'transform'
-  });
-  // → '[#\*0-9]'
-  ```
-
-  By default, patterns with the `v` flag are transformed to patterns with the `u` flag. If you want to downlevel them more you can set the `unicodeFlag: 'transform'` option.
-
-  ```js
-  rewritePattern('[^[a-h]&&[f-z]]', 'v', {
-    unicodeSetsFlag: 'transform'
-  });
-  // → '[^f-h]' (to be used with /u)
-  ```
-
-  ```js
-  rewritePattern('[^[a-h]&&[f-z]]', 'v', {
-    unicodeSetsFlag: 'transform',
-    unicodeFlag: 'transform'
-  });
-  // → '(?:(?![f-h])[\s\S])' (to be used without /u)
-  ```
-
-- `modifiers` - [Inline `m`/`s`/`i` modifiers](https://github.com/tc39/proposal-regexp-modifiers)
-
-  ```js
-  rewritePattern('(?i:[a-z])[a-z]', '', {
-    modifiers: 'transform'
-  });
-  // → '(?:[a-zA-Z])([a-z])'
-  ```
-
-#### Miscellaneous options
-
-- `onNamedGroup`
-
-  This option is a function that gets called when a named capture group is found. It receives two parameters:
-  the name of the group, and its index.
-
-  ```js
-  rewritePattern('(?<name>.)\\k<name>', '', {
-    onNamedGroup(name, index) {
-      console.log(name, index);
-      // → 'name', 1
-    }
-  });
-  ```
-
-- `onNewFlags`
-
-  This option is a function that gets called to pass the flags that the resulting pattern must be interpreted with.
-
-  ```js
-  rewritePattern('abc', 'um', '', {
-    unicodeFlag: 'transform',
-    onNewFlags(flags) {
-      console.log(flags);
-      // → 'm'
-    }
-  })
-  ```
-
-### Caveats
-
-- [Lookbehind assertions](https://github.com/tc39/proposal-regexp-lookbehind) cannot be transformed to older syntax.
-- When using `namedGroups: 'transform'`, _regexpu-core_ only takes care of the _syntax_: you will still need a runtime wrapper around the regular expression to populate the `.groups` property of `RegExp.prototype.match()`'s result. If you are using _regexpu-core_ via Babel, it's handled automatically.
-
-## For maintainers
-
-### How to publish a new release
-
-1. On the `main` branch, bump the version number in `package.json`:
-
-    ```sh
-    npm version patch -m 'Release v%s'
-    ```
-
-    Instead of `patch`, use `minor` or `major` [as needed](https://semver.org/).
-
-    Note that this produces a Git commit + tag.
-
-1. Push the release commit and tag:
-
-    ```sh
-    git push --follow-tags
-    ```
-
-    Our CI then automatically publishes the new release to npm.
-
-1. Once the release has been published to npm, update [`regexpu`](https://github.com/mathiasbynens/regexpu) to make use of it, and [cut a new release of `regexpu` as well](https://github.com/mathiasbynens/regexpu#how-to-publish-a-new-release).
