ActiveState Releases Advanced IDE for Ruby on Rails

VANCOUVER, British Columbia – May 17, 2007 – ActiveState, the leading provider of tools and services for dynamic languages, released the latest version of Komodo IDE today at RailsConf 2007, introducing unparalleled Ruby and Ruby on Rails support to the award-winning development environment. Komodo IDE 4.1 is a multi-platform, multi-language IDE for dynamic languages and Ajax technologies, now featuring the most advanced Ruby and Rails editing and debugging available in any development tool.

Powerful development framework Ruby on Rails is a popular choice for developers seeking to create sophisticated web applications with ease. Komodo IDE 4.1 extends this power and flexibility with state-of-the art debugging, including support for Rails controllers and views, and a Ruby interactive shell, available on its own or from within debugging sessions. The feature-rich editor guides developers with autocomplete and calltips for Ruby and RHTML, and supports the multi-language and templated files common in Rails development. Komodo IDE 4.1 also introduces a Rails project template for painless project creation. New projects are generated with a single click, and populated with a host of useful commands for database setup and application testing.

"The last major release of Komodo redefined what was possible in a web development IDE," says Eric Promislow, senior Komodo developer. "But given the wild popularity of Ruby on Rails, we wanted to do more. Komodo IDE 4.1 is a definitive moment in Rails development, introducing more advanced tools and better performance than Rails developers have seen so far. There are new Rails-powered sites appearing every day. Increasingly, we expect those to be developed using Komodo IDE."

Komodo IDE's extensible architecture is another boon for Rails developers. Built on the Mozilla platform, Komodo IDE features XPI extension support, providing the same extensibility as Firefox, with all standard Mozilla APIs based on XUL, XBL and XPCOM, plus ActiveState's own for Python and JavaScript. A new Rails-oriented library makes it easy for developers to customize Komodo, add new commands, and share them with others. Komodo IDE 4.1 includes full macro API documentation, further backed by Ruby tutorials and an active community sharing valuable extensions through ActiveState's community site at

As with previous releases, Komodo IDE features intelligent tools for regular expressions, team development, customization and unparalleled extensibility. The result is a powerful coding environment not only for Ruby on Rails, but also CakePHP and client libraries such as the Yahoo! UI Library and Dojo. A single license covers users across Windows, Mac OS X and Linux.
