You should upgrade to `1.x`. ## Usage ```javascript var pathToRegexp = require('path-to-regexp'); ``` ### pathToRegexp(path, keys, options) - **path** A string in the express format, an array of such strings, or a regular expression - **keys** An array to be populated with the keys present in the url. Once the function completes, this will be an array of strings. - **options** - **options.sensitive** Defaults to false, set this to true to make routes case sensitive - **options.strict** Defaults to false, set this to true to make the trailing slash matter. - **options.end** Defaults to true, set this to false to only match the prefix of the URL. ```javascript var keys = []; var exp = pathToRegexp('/foo/:bar', keys); //keys = ['bar'] //exp = /^\/foo\/(?:([^\/]+?))\/?$/i ``` ## Live Demo You can see a live demo of this library in use at [express-route-tester](http://forbeslindesay.github.com/express-route-tester/). ## License MIT PK`@[.]= History.mdnuW+A„¶0.1.7 / 2015-07-28 ================== * Fixed regression with escaped round brackets and matching groups. 0.1.6 / 2015-06-19 ================== * Replace `index` feature by outputting all parameters, unnamed and named. 0.1.5 / 2015-05-08 ================== * Add an index property for position in match result. 0.1.4 / 2015-03-05 ================== * Add license information 0.1.3 / 2014-07-06 ================== * Better array support * Improved support for trailing slash in non-ending mode 0.1.0 / 2014-03-06 ================== * add options.end 0.0.2 / 2013-02-10 ================== * Update to match current express * add .license property to component.json PK`@[`ó¢OOLICENSEnuW+A„¶The MIT License (MIT) Copyright (c) 2014 Blake Embrey (hello@blakeembrey.com) Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
