Should watch: Dave Herman: The Future of JavaScript #ECMAScript6

Posted by jpluimers on 2012/01/11

On:

Mozilla Labs engineer and TC39 representative Dave Herman joined us at YUIConf 2011 to give this keynote talk on the future of JavaScript, covering many of the new features currently under consideration for ES6, the next edition of the ECMAScript standard.

Many wonderful new features. Now it just need some great tooling.

Delphi Labs: DataSnap XE and jQueryMobile; a Web Frontend accessing DataSnap through a Delphi WebBroker server

Posted by jpluimers on 2011/03/22

[Wayback] Paweł Głowacki recently released two very interesting blog articles, together with 5 (five!) demonstration videos on how to get your mobile device to talk to a DataSnap backend using [Wayback] jQueryMobile so you get a very native look & feel UI on your mobile device without putting a lot of effort in writing a native device app.

  1. [Wayback] Part 1: Delphi Labs: DataSnap XE – WebBroker jQueryMobile Boilerplate – DelphiFeeds.com.
  2. [Wayback] Part 2: Delphi Labs: DataSnap XE – jQueryMobile Web Frontend – DelphiFeeds.com.

Highly recommended!

Regular expressions and the ASP.NET RegularExpressionValidator control – an overview of useful links

Posted by jpluimers on 2009/09/10

Every now and then I need the ASP.NET RegularExpressionValidator control to validate some user input on a web-page using .NET Regular Expressions (which are very similar to regular expressions used in other languages and frameworks).

Somehow, I have lost loads of time because many of the hits on Google show up high in the results, but do not actually help that much.

So I decided to put up a bunch of links to pages that I think are relevant, or helped me much.
This list is not definitive: please comment when you have links to better information!

Note: this list is current at the instant of the latest edit timestamp: tools might have improved (or disappeared) since then.
Opnions are mine; if you do not agree: please convince me why.

Tools

Regular Expression builder applications

  • Expresso – free .NET WinForms application to visually build and test regular expressions (free registraion required after 60 days of trial usage)
  • RegexWorkbench – free .NET WinForms application to build and test regular expressions (much more rudimentary than Expresso)

Regular Expression test applications

  • RegexLib tester – free on-line regular expresion tester where you can choose the client platform (.NET/ClientSide/SilverLight)
  • The Regulator – free .NET WinForms application to test regular expressions with built in support for RegexLib.com
  • The Regex Coach – free LISP Windows application to test regular expressions and tries to explain them in plain english
  • RegExPal – free on-line JavaScript regular expression tester (tests the client side only)
  • ReWork – free on-line JavaScript tester with samples in JavaScript/PHP/Python/Ruby
  • RegexDesigner.NET – free .NET WinForms application to test regular expressions and generate C#/VB.NET code from them (ot really a “Designer” after all and much less sophisticated than The Regulator)

Tools lists

Tools not worth looking at

  • Regulazy – too rudimentary

Sites/Documentation/Examples

Some comments on common regular expression solutions

  • RegEx for email usuaully reject valid email adresses like jeroen+info@pluimers.subdomain.info
    Dominic has some very nice info on validating email adresses
  • RegEx for a minimum number of characters usually contain \w, which is not any character!
    Better use ^(.{6,})$ than ^(\w{6,})$ if you want a minimum length of 6 characters.
