It looks a great announcement from Google: Closure tools, a collection of JavaScript tools that Google has used to develop our JavaScript-intensive applications such as Gmail, Google Maps and Google Docs.
It consists of the Closure Compiler, Closure Library, Closure Inspector and Closure Templates. The internal names of these tools are JSCompiler, Closure, LavaBug and Soy Templates. For Closure Compiler, we also released a web application, a RESTful API and a Firefox extension that you can use with Page Speed.
All of these tools started as 20% projects and over the years hundreds of Googlers have contributed thousands of patches. Today, a few hundred projects within Google use some of the tools such as the Closure Library and the Closure Compiler.
Millions of Google users worldwide use JavaScript-intensive applications such as Gmail, Google Docs, and Google Maps. Like developers everywhere, Googlers want great web apps to be easier to create, so we've built many tools to help us develop these (and many other) apps. We're happy to announce the open sourcing of these tools, and proud to make them available to the web development community.
