CommonRegex port for JavaScript

Find a lot of kinds of common information in a string.

Pull requests welcome!

Please note that this is currently English/US specific.

Usage

You can use CommonRegexJS normally, using a script tag:

  <script src="commonregex.js"></script> 

Or importing it with RequireJS, putting commonregex.js file inside your RequireJS base directory, using like this:

  requirejs(['commonregex'], function(CommonRegex) {
      //Use CommonRegex normally here
  }

Or install via NPM with

  $ npm install commonregex

And use like this:

  import CommonRegex from 'commonregex'; // For ES6 environments
 
  var CommonRegex = require('commonregex'); // For ES5 environments

API

You can instantiate a CommonRegex object passing a string in the constructor and use the fields of the object to acess the matches and the methods for the matches of other strings (passing the string as parameter), or not pass a string in the constructor and just use the methods.

Possible properties and its equivalent methods:

• #dates or #getDates([text])
• #times or #getTimes([text])
• #phones or #getPhones([text])
• #links or #getLinks([text])
• #emails or #getEmails([text])
• #IPv4 or #getIPv4([text])
• #IPv6 or #getIPv6([text])
• #hexColors or #getHexColors([text])
• #acronyms or #getAcronyms([text])
• #money or #getMoney([text])
• #percentages or #getPercentages([text]) (matches percentages between 0.00% and 100.00%)
• #creditCards or #getCreditCards([text])
• #addresses or #getAddresses([text])

The regexes used internally are available at CommonRegex.regexes.

Examples

var text = 'John, please get that article on www.linkedin.com to me by 5:00PM\n'
+ 'on Jan 9th 2012. 4:00 would be ideal, actually. If you have any questions,\n'
+ 'you can reach my associate at [phone] or [e-mail].\n'
+ 'I\'ll be on UK during the whole week on a J.R.R. Tolkien convention.';

var commonRegex = new CommonRegex(text);
console.log(commonRegex.dates);
//logs ["Jan 9th 2012"]
console.log(commonRegex.times);
//logs ["5:00PM", "4:00"]
console.log(commonRegex.phones);
//logs ["[phone]"]
console.log(commonRegex.links);
//logs ["www.linkedin.com"]
console.log(commonRegex.emails);
//logs ["[e-mail]"]
console.log(commonRegex.getAcronyms());
//logs ["UK", "J.R.R."]

Alternatively, you can generate a single CommonRegex instance and use it to parse multiple segments of text.

var commonRegex = new CommonRegex();
console.log(commonRegex.times('When are you free? Do you want to meet up for coffee at 4:00?''));
//logs ["4:00"]
console.log(commonRegex.getMoney('They said the price was US$5,000.90, actually it is US$3,900.5. It\'s $1100.4 less, can you imagine this?'));
//logs ["US$5,000.90", "US$3,900.5", "$1100.4"]
console.log(commonRegex.getPercentages('I\'m 99.9999999% sure that I\'ll get a raise of 5%.'));
//logs ["99.9999999%", "5%"]
console.log(commonRegex.getIPv6('The IPv6 address for localhost is 0:0:0:0:0:0:0:1, or alternatively, ::1.'));
//logs ["0:0:0:0:0:0:0:1", "::1"]
