unicode-match-property-value-ecmascript
unicode-match-property-value-ecmascript matches a given Unicode property value or property value alias to its canonical property value 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-value-ecmascript programmatically, install it as a dependency via npm:
$ npm install unicode-match-property-value-ecmascript
Then, require
it:
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.
// 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
