Installation

To use unicode-property-value-aliases programmatically, install it as a dependency via npm:

$ npm install unicode-property-value-aliases

Then, require it:

const propertyValueAliases = require('unicode-property-value-aliases');

Usage

This module exports a Map object of which the keys are canonical property names and the values are Maps from property value aliases to canonical property value names. The most common usage is to convert a property value alias to its canonical form:

propertyValueAliases.get(property).get(propertyValue)

Examples:

propertyValueAliases.get('Bidi_Class').get('AL')
// → 'Arabic_Letter'

propertyValueAliases.get('Block').get('Alphabetic_PF')
// → 'Alphabetic_Presentation_Forms'

propertyValueAliases.get('Canonical_Combining_Class').get('KV')
// → 'Kana_Voicing'

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.
