The envjs rubygem is a port of the env.js project based on the Johnson gem. The env.js project provides a mostly pure javascript implementation of the browser environment (e.g., the HTML DOM objects). More details on env.js are available at http://github.com/thatcher/env-js.

The original target of env.js was the Rhino javascript interpreter written in Java. The envjs gem uses the SpiderMonkey interpreter written in C/C++ via the Johnson gem.

The 0.1 release branch of the envjs gem is not integrated with the Java version. The 1.0 release branch is expected to be.

To install envjs, you may need to manually install a prerelease of the johnson gem, e.g.,

gem install johnson --prerelease

Simple examples are in the README at http://github.com/smparkes/env-js.

This release represents a significant refactoring of the scope mechanisms used in env.js. The result is a significant increase in speed. A number of memory leaks were also fixed. Thanks to the great tests included with capybara, a number of DOM and event issues were also fixed,. This version of env.js is compatible with the capybara env.js driver support in git://github.com/smparkes/capybara.git.
