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
