Installation

`` bash
$ npm install utils-regex-from-string
`

Usage

` javascript
var regex = require( 'utils-regex-from-string' );

#### regex( str )

Parses a regular expression string and returns a new regular expression.

`

__Note__: provided strings must be properly __escaped__.

// returns /w+/

// Escaped:
re = regex( '/\\w+/' );
// returns /\w+/
`

Examples

` javascript
var regex = require( 'utils-regex-from-string' );

console.log( regex( '/beep/' ) );
// returns /beep/

console.log( regex( '/[A-Z]*/' ) );
// returns /[A-Z]*/

console.log( regex( '/\\\\\\\//ig' ) );
// returns /\\\//ig

console.log( regex( '/[A-Z]{0,}/' ) );
// returns /[A-Z]{0,}/

console.log( regex( '/^boop$/' ) );
// returns /^boop$/

console.log( regex( '/(?:.*)/' ) );
// returns /(?:.*)/

console.log( regex( '/(?:beep|boop)/' ) );
// returns /(?:beep|boop)/

console.log( regex( '/\\w+/' ) );
// returns /\w+/

To run the example code from the top-level application directory,

` bash
$ node ./examples/index.js
`

Tests

Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

` bash
$ make test
`

All new feature development should have corresponding unit tests to validate correct functionality.

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

` bash
$ make test-cov
`

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

` bash
$ make view-cov
