More info here. http://www.eahanson.com/2008/05/18/new-test-runner-for-jsunit/ A while ago, I wrote about a Ruby script to concatenate and compress Javascript files for my wshlst application. I've changed things around a bit since that article, so I thought it was time for an update. Background wshlst uses a lot of Javascript.

Also, I wanted to be able to view any test page so I could ... http://www.eahanson.com/2007/05/26/a-ruby-script-to-generate-a-jsunit-suite/ I often want to add a bunch of styles to an element, so I wrote a stylize method so I can do something like this: $("foo").stylize({ color: red, background-color: green, text-decoration: underline }); Implementing stylize is easy with Prototype's Element.addMethods() method: var ElementExtensions = { stylize: function(element, styles) { ... http://www.eahanson.com/2007/05/25/elementstylize-via-prototypejs/ When installing Capistrano, you should install the termios gem so that your password isn't echoed when you type it.

I also read about dwatch but I figured a service ... http://www.eahanson.com/2007/01/14/free-website-monitoring/ Sometimes I find that I want to debug a JsUnit test because I'm not quite sure what's going on in the browser. FireBug has a nice debugger, but I couldn't get it to work with the JsUnit test runner. I could set breakpoints in JsUnit itself, but any breakpoints in my ... http://www.eahanson.com/2006/11/16/debugging-a-jsunit-test-with-firebug/ I wanted my Bash prompt to be bold and red so I could find my one line of input amongst the million lines of output in my terminal.

After a bunch of Googling, I ... http://www.eahanson.com/2006/02/12/a-bold-prompt-in-bash/ I had a little trouble today with join tables that contain attributes.

Reading attributes I added an attribute ... http://www.eahanson.com/2006/02/12/join-tables-with-attributes-in-rails/ Google's AJAXSLT library is very nice, but it is lacking in documentation and sometimes hard to figure out.

Note: ... http://www.eahanson.com/2005/09/30/how-to-use-googles-ajaxslt-library/ I'm working on a Ruby project using Eclipse and RDT. RDT provides a couple useful features, including support for running unit tests with Test::Unit. Unfortunately, it's pretty primitive at the moment.
