Turn an Express-style path string such as/user/:name into a regular expression.

Note: This is a legacy branch. You should upgrade to1.x.

varpathToRegexp=require('path-to-regexp');

• 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.

varkeys=[];varexp=pathToRegexp('/foo/:bar',keys);//keys = ['bar']//exp = /^\/foo\/(?:([^\/]+?))\/?$/i
