version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Coverage Status][codecov-image]][codecov-url] [![Dependencies][dependencies-image]][dependencies-url]\n\n> Parses a [regular expression](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) string and returns a new [regular expression](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions).\n\n\n## Installation\n\n``` bash\n$ npm install utils-regex-from-string\n```\n\n\n## Usage\n\n``` javascript\nvar regex = require( 'utils-regex-from-string' );\n```\n\n#### regex( str )\n\nParses a [regular expression](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) `string` and returns a new [regular expression](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions).\n\n``` javascript\nvar re = regex( '/beep/' )\n// returns /beep/\n```\n\n__Note__: provided `strings` must be properly __escaped__.\n\n``` javascript\n// Unescaped:\nre = regex( '/\\w+/' );\n// returns /w+/\n\n// Escaped:\nre = regex( '/\\\\w+/' );\n// returns /\\w+/\n```\n\n\n## Examples\n\n``` javascript\nvar regex = require( 'utils-regex-from-string' );\n\nconsole.log( regex( '/beep/' ) );\n// returns /beep/\n\nconsole.log( regex( '/[A-Z]*/' ) );\n// returns /[A-Z]*/\n\nconsole.log( regex( '/\\\\\\\\\\\\\\//ig' ) );\n// returns /\\\\\\//ig\n\nconsole.log( regex( '/[A-Z]{0,}/' ) );\n// returns /[A-Z]{0,}/\n\nconsole.log( regex( '/^boop$/' ) );\n// returns /^boop$/\n\nconsole.log( regex( '/(?:.*)/' ) );\n// returns /(?:.*)/\n\nconsole.log( regex( '/(?:beep|boop)/' ) );\n// returns /(?:beep|boop)/\n\nconsole.log( regex( '/\\\\w+/' ) );\n// returns /\\w+/\n```\n\nTo run the example code from the top-level application directory,\n\n``` bash\n$ node ./examples/index.js\n```\n\n\n## Tests\n\n### Unit\n\nUnit tests use the [Mocha](http://mochajs.org/) test framework with [Chai](http://chaijs.com) assertions. To run the tests, execute the following command in the top-level application directory:\n\n``` bash\n$ make test\n```\n\nAll new feature development should have corresponding unit tests to validate correct functionality.\n\n\n### Test Coverage\n\nThis repository uses [Istanbul](https://github.com/gotwarlost/istanbul) as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:\n\n``` bash\n$ make test-cov\n```\n\nIstanbul creates a `./reports/coverage` directory. To access an HTML version of the report,\n\n``` bash\n$ make view-cov\n```\n\n\n---\n## License\n\n[MIT license](http://opensource.org/licenses/MIT).\n\n\n## Copyright\n\nCopyright © 2015.
