regenerate

What is regenerate?

The 'regenerate' npm package is a tool for creating sets of Unicode symbols and generating regular expressions to match them. It is particularly useful for working with Unicode properties and ranges, making it easier to handle complex character sets in a concise and readable manner.

What are regenerate's main functionalities?

Creating a set of Unicode symbols

This feature allows you to create a set of Unicode symbols by adding individual characters or ranges of characters. In this example, a set containing all uppercase and lowercase English letters is created.

const regenerate = require('regenerate');
const set = regenerate().addRange(0x0041, 0x005A).addRange(0x0061, 0x007A);
console.log(set.toString()); // Output: '[A-Za-z]'

Generating regular expressions

This feature allows you to generate a regular expression from the set of Unicode symbols. The example demonstrates creating a regular expression that matches any uppercase or lowercase English letter.

const regenerate = require('regenerate');
const set = regenerate().addRange(0x0041, 0x005A).addRange(0x0061, 0x007A);
const regex = set.toRegExp();
console.log(regex); // Output: /[A-Za-z]/

Adding individual characters

This feature allows you to add individual Unicode characters to the set. In this example, the set contains the characters 'A' and 'a'.

const regenerate = require('regenerate');
const set = regenerate().add(0x0041).add(0x0061);
console.log(set.toString()); // Output: '[Aa]'

Removing characters or ranges

This feature allows you to remove individual characters or ranges of characters from the set. In this example, the character 'A' is removed from a set of uppercase English letters.

const regenerate = require('regenerate');
const set = regenerate().addRange(0x0041, 0x005A).remove(0x0041);
console.log(set.toString()); // Output: '[B-Z]'

Other packages similar to regenerate

xregexp

XRegExp provides augmented (extended) regular expressions. It includes support for Unicode properties, named capture groups, and other features not found in native JavaScript regular expressions. Compared to 'regenerate', XRegExp offers a broader range of regex enhancements but may be more complex to use for simple Unicode set operations.

unicode-regex

The 'unicode-regex' package provides utilities for generating regular expressions that match Unicode characters and properties. It is similar to 'regenerate' but focuses more on providing pre-defined sets for common Unicode properties and categories.
