CommonJS wrapper for regex-recursion.

Installation

``bash
pnpm add regex-recursion-cjs
`

Usage

`js
// CommonJS
const { recursion } = require('regex-recursion-cjs');

// Use recursion to process a regex with recursive patterns
const pattern = '\\((?:(?R=2)|[^()])\\)';
const result = recursion(pattern);
console.log(result.pattern); // Processed pattern with recursion transformed
`

#### Nested Parentheses Matching

`js
const { recursion } = require('regex-recursion-cjs');

// Create a pattern that matches balanced parentheses
const pattern = '\\((?:(?R=10)|[^()])*\\)';
const processed = recursion(pattern);

// The processed pattern can be used with a standard RegExp
const regex = new RegExp(processed.pattern);
const text = 'foo (bar (baz) blah) end';
console.log(text.match(regex)[0]); // '(bar (baz) blah)'
`

#### Using Named Groups with Recursion

`js
const { recursion } = require('regex-recursion-cjs');

// Use named groups with recursion
const pattern = '\\((?(?:\\g|[^()]))\\)';
const processed = recursion(pattern);

console.log(processed.pattern); // Shows the expanded pattern

This project uses ts-standard for linting and code formatting, which is an extension of StandardJS for TypeScript.

`bash


Run linting

pnpm lint

Fix linting issues automatically

pnpm lint:fix
`

Pre-commit hooks (using Husky and lint-staged) ensure that code is properly linted before being committed.

`bash


Clean build artifacts

pnpm clean

Build the package

pnpm build

Run tests

pnpm test

Development workflow (clean, build, test)

pnpm dev
`

Why

The original regex-recursion` package is ESM-only, which can cause compatibility issues in CommonJS projects. This package provides a pre-built CommonJS version that can be used in any Node.js environment without the need for special configuration.
