# unicode-match-property-value-ecmascript [![Build status](https://travis-ci.org/mathiasbynens/unicode-match-property-value-ecmascript.svg?branch=main)](https://travis-ci.org/mathiasbynens/unicode-match-property-value-ecmascript) [![unicode-match-property-value-ecmascript on npm](https://img.shields.io/npm/v/unicode-match-property-value-ecmascript)](https://www.npmjs.com/package/unicode-match-property-value-ecmascript) |
|
|
|
_unicode-match-property-value-ecmascript_ matches a given Unicode property value or [property value alias](https://github.com/mathiasbynens/unicode-property-value-aliases) to its canonical property value without applying [loose matching](https://github.com/mathiasbynens/unicode-loose-match), per the algorithm used for [RegExp Unicode property escapes in ECMAScript](https://github.com/tc39/proposal-regexp-unicode-property-escapes). Consider it a strict alternative to loose matching. |
|
|
|
## Installation |
|
|
|
To use _unicode-match-property-value-ecmascript_ programmatically, install it as a dependency via [npm](https://www.npmjs.com/): |
|
|
|
```bash |
|
$ npm install unicode-match-property-value-ecmascript |
|
``` |
|
|
|
Then, `require` it: |
|
|
|
```js |
|
const matchPropertyValue = require('unicode-match-property-value-ecmascript'); |
|
``` |
|
|
|
## API |
|
|
|
This module exports a single function named `matchPropertyValue`. |
|
|
|
### `matchPropertyValue(property, value)` |
|
|
|
This function takes a string `property` that is a canonical/unaliased Unicode property name, and a string `value`. It attemps to match `value` to a canonical Unicode property value for the given property. If there’s a match, it returns the canonical property value. Otherwise, it throws an exception. |
|
|
|
```js |
|
// Find the canonical property value: |
|
matchPropertyValue('Script_Extensions', 'Aghb') |
|
// → 'Caucasian_Albanian' |
|
|
|
matchPropertyValue('Script_Extensions', 'Caucasian_Albanian') |
|
// → 'Caucasian_Albanian' |
|
|
|
matchPropertyValue('script_extensions', 'Caucasian_Albanian') // Note: incorrect casing. |
|
// → throws |
|
|
|
matchPropertyValue('Script_Extensions', 'caucasian_albanian') // Note: incorrect casing. |
|
// → throws |
|
``` |

### 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. |
