## README

# regenerate-unicode-properties [![regenerate-unicode-properties on npm](https://img.shields.io/npm/v/regenerate-unicode-properties)](https://www.npmjs.com/package/regenerate-unicode-properties)

_regenerate-unicode-properties_ is a collection of [Regenerate](https://github.com/mathiasbynens/regenerate) sets for [various Unicode properties](https://github.com/tc39/proposal-regexp-unicode-property-escapes).

## Installation

To use _regenerate-unicode-properties_ programmatically, install it as a dependency via [npm](https://www.npmjs.com/):

```bash
$ npm install regenerate-unicode-properties
```

## Usage

To get a map of supported properties and their values:

```js
const properties = require('regenerate-unicode-properties');
```

To get a specific Regenerate set:

```js
// Examples:
const Lu = require('regenerate-unicode-properties/General_Category/Uppercase_Letter.js').characters;
const Greek = require('regenerate-unicode-properties/Script_Extensions/Greek.js').characters;
```

Some properties can also refer to strings rather than single characters:
```js
const { characters, strings } = require('regenerate-unicode-properties/Property_of_Strings/Basic_Emoji.js');
```

To get the Unicode version the data was based on:

```js
const unicodeVersion = require('regenerate-unicode-properties/unicode-version.js');
```

## 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 && git push --tags
    ```

    Our CI then automatically publishes the new release to npm.
