unicode-match-property-ecmascript

unicode-match-property-ecmascript matches a given Unicode property or property alias to its canonical property name without applying loose matching per the algorithm used for RegExp Unicode property escapes in ECMAScript. Consider it a strict alternative to loose matching.

Installation

To use unicode-match-property-ecmascript programmatically, install it as a dependency via npm:

$ npm install unicode-match-property-ecmascript

Then, require it:

const matchProperty = require('unicode-match-property-ecmascript');

API

This module exports a single function named matchProperty.

matchProperty(value)

This function takes a string value and attempts to match it to a canonical Unicode property name. If there’s a match, it returns the canonical property name. Otherwise, it throws an exception.

// Find the canonical property name:
matchProperty('sc')
// → 'Script'

matchProperty('Script')
// → 'Script'

matchProperty('script') // Note: incorrect casing.
// → throws

For maintainers

How to publish a new release

1. On the main branch, bump the version number in package.json:

   npm version patch -m 'Release v%s'
   

   Instead of patch, use minor or major as needed.

   Note that this produces a Git commit + tag.

2. Push the release commit and tag:

   git push && git push --tags
   

   Our CI then automatically publishes the new release to npm.
