Create regex from natural language

Attention - This project isn't completed yet. There might be breaking changes until version 1.0.0. Feel free to contribute, see TODO to get started.

natural-regex is a parser that allows you to write regular expressions in natural language. This means that you can write self documentating regex using a simpler syntax that can be undestood by anyone. No more pain with validations and other stuff.

Installation

You can install natural-regex using npm:

npm install --save natural-regex

If you aren't using npm in your project, you can include NaturalRegex using UMD build in the dist folder with <script> tag.

Usage

Once you have installed natural-regex, supposing a CommonJS environment, you can import and immediately use it:

import NaturalRegex from 'natural-regex';
// validate string
const dateAndEmail = NaturalRegex.from('starts with dd/MM/yyyy, space, minus, space and then email, end.');
dateAndEmail.test('06/07/2016 - foo@bar.com'); // this evaluates true
dateAndEmail.test('Foo Bar foo@bar'); // this evaluates false

// replace in string
NaturalRegex.replace({
  string: '06/07/2014 - foo@bar.com',
  match: 'yyyy',
  replace: '2016',
});
// this returns '06/07/2016 - foo@bar.com'

NaturalRegex also includes a command line tool, check this for more information.
