Refaved from Mike

.Net, the DLR (Dynamic Language Runtime), and Ruby.

Quoted: ASP.NET, Visual Studio, ASP.NET 2.0, .NET

This has gotten some good mentions, but it's $300. This was Perl and Tcl initially and they've added other things like Ruby. Not clear how well it works for those.

Quoted: Professional IDE for JavaScript, Perl, PHP, Python, Ruby and Tcl on Linux, Mac OS X and Windows. Provides a powerful workspace for editing and debugging scripting languages.

I tried this a while back and and wasn't impressed.

Quoted: EasyEclipse is an open source Eclipse distribution.

Quoted: Web Hosting Services Which Support Ruby on Rails

Quoted: RadRails development is now headed by Aptana, and is a feature of the Aptana Studio suite. RadRails remains open source, under APL/GPL, and free. To keep up with the latest developments check out the blog posts about Rails, the RadRails sections on our forums, or the Trac tickets. Or if you want, just skip ahead to updating.

So what's changed? A lot! RadRails now includes many more advanced features including fast server debugging, code completion with type inferrencing, CSS/HTML/JS code editors and code assist, multi-language contextual code assist inside RHTML files (code assist for CSS, JS, HTML and Ruby depending on the context of the cursor), type hierarchy view, go to declaration, call hierarchy (trace method call paths), and much, much more!

Quoted: Rails is well documented on-line; in fact, possibly too well documented for beginners, with over 30,000 words of on-line documentation in the format of a reference manual. What's missing is a roadmap (railmap?) pointing to the key pages that you need to know to get up and running in Rails development. Four Days on Rails is designed to fill that gap. It's about 40 pages formatted for double-sided printing on A4, and by the time you've read it, you should have a useful toolbox of Rails techniques and a good idea of where to look on the web for more information. The current version of this document is 2.0.

Quoted: mHub is a constantly updated list of web applications, services, resources, blogs or sites with a focus on next generation web (web 2.0), blogging, Ajax, Ruby, Rails and open source developments ...

Quoted: Sometimes it’s nice to have a self contained click-’n-run web-server - this way you are not dependent on presence of Apache, Mongrel, or any other 3rd party package. One way to go about this, is to do some socket programming. However, sockets may be too low-level for comfort, instead we can leverage yet another great Ruby library: WEBrick. Most Rails developers will be very familiar with WEBRick, but most don’t realize how powerful it can be for quick mock-ups and one-off proofs of concept.
