What is regexpu-core?

The regexpu-core package is a utility that helps in transforming Unicode-aware regular expressions into ES5-compatible versions. This is particularly useful when you want to ensure your regular expressions work across environments that may not fully support ES6 Unicode features.

What are regexpu-core's main functionalities?

Transform Unicode regular expressions

This feature allows you to transform a Unicode regular expression into an ES5-compatible version. The example shows how to transform a pattern that matches any letter using Unicode property escapes.

const rewritePattern = require('regexpu-core');
const pattern = rewritePattern('\\p{L}', 'u');
console.log(pattern); // Transformed pattern that matches any letter

Use with flags

This feature enables the transformation of Unicode regular expressions with specific flags. In the example, the 'useUnicodeFlag' option is used to indicate that the Unicode flag should be preserved in the transformed pattern.

const rewritePattern = require('regexpu-core');
const pattern = rewritePattern('\\p{L}', 'u', { 'useUnicodeFlag': true });
console.log(pattern); // Transformed pattern with the Unicode flag enabled
