Dear devs, The Nitro Development Team is proud to announce new versions of Nitro and Og homepage: [http://www.nitrohq.com](http://www.nitrohq.com) install: gem install nitro download: [http://rubyforge.org/projects/nitro/](http://rubyforge.org/projects/nitro/) trac: [oree.ch](http://devlab.oree.ch/trac/nitrohq) irc: [irc.freenode.net](http://irc.freenode.net) #nitro faq: [http://oxyliquit.manveru.net](http://oxyliquit.manveru.net) mailing list: [http://rubyforge.org/pipermail/nitro-general/](http://rubyforge.org/pipermail/nitro-general/) A bold step towards maturity. Great care was taken to fix reported bugs and fine tune many aspects of Nitro and Og. As always some great new features where added. Special thanks fly to Jonas P., Bryan Sotto, Rob Pitt and Guillaume Pierronnet for making this release possible. Most notable changes: - Greatly improved error detection and report. Nitro now provides line exact error reports at compile or run time, in actions or templates. Stay tuned for more improvements in error handling. - Nitro now supports a very useful url endoding/decoding system along with a Camping inspired R operator. This new system allows you to refer to controllers and actions in your code, without bothering about the enforced nice urls and rewrite/routing rules. This allows you to write more robust code. - To better support the URL codec, a new router was implemented. The new version is both more powerfull and faster. Here are some examples: - Og now supports calculations and aggregations. Here are some examples: - Improved template\_root handling. Now Nitro automatically generates a template\_root stack for each controller / publishable object. Of course the developer can fully customize this stack. This is great for reusable modules of functionality (parts). Lets say you have implemented a forum part. When you ‘mount’ the forum controller a path relative to the mount point is pushed in the template\_root stack. When the dispatcher searches for a template, it traverses the stack. In the described scenario it first looks in the application template root, next in a template root the points inside the part template root and then in the proto dir template root. The proto dir template root is automatically pushed as the last root in the stack. This system facilitates ‘object oriented sites’. - Added support for JSP like application scoped (global) variables. - Improved Taggable mixin, now provides more helpers and supports tag garbage collection through reference counting. - Added a new store for the generalized caching system that is backed by a MemCache server. Useful to extract the last ounch of performance in a production environment. - Fixes in the SCGI adapter. - Many Og bug fixes and optimizations. - More flexible static include compiler. - Improved testing support. - Integrated latest versions of Scriptaculous and Facets. - Many, many bug fixes and small improvements throughout the code. Nitro provides everything you need to develop professional Web applications using Ruby and Javascript. Nitro redefines Rapid Application Development by providing a clean, yet efficient API, a layer of domain specific languages implemented on top of Ruby and the most powerful and elegant object relational mapping solution available everywhere. have fun, George M. ---
