    Regex

    Native RegExp compatible regular expressions for JavaScript. Patterns may be composed of subexpressions and multiple expressions may be combined into a single expression.

    Installation

    Regex may be installed on node.js via the node package manager using the command npm install regex.

    You may also install it on RingoJS using the command ringo-admin install aaditmshah/regex.

    You may install it as a component for web apps using the command component install aaditmshah/regex.

    Usage

    The Regex constructor is compatible with the native RegExp constructor. You may pass it a regexp object or a source string:

    var Regex = require("regex");
    var regex = new Regex(/(a|b)*abb/);

    Methods

    Like the native RegExp constructor instances of Regex have the following methods:

    test

    The test method is used to simply test whether a string matches the regex pattern:

    regex.test("abb");   // true
    regex.test("aabb");  // true
    regex.test("babb");  // true
    regex.test("aaabb"); // true
    regex.test("ababb"); // true
    regex.test("abba");  // false
    regex.test("cabb");  // false

    Operations

    The Regex constructor currently supports the following regex operations:

    1. Concatenation
    2. Alternation
    3. Grouping
    4. Closure

    Changelog
