What IDE / Editor do you use for Ruby on Windows? [closed]
You can use either Eclipse with the Aptana Plugin and then install the Aptana RadRails plugin or you can use Aptana as a stand-alone application.
I like to use Eclipse with the Aptana plugins because Aptana seems to provide the best support for HTML, Javascript, and CSS that I've seen in an Eclipse plugin, and you still get the full benefit of using the core Eclipse application.
