code coverage for JavaScript

## News

### December 11, 2008 - JSCoverage 0.4

JSCoverage 0.4 is available for download.

This release includes many new features:

- The new `jscoverage-server` program is provided as an alternative to the `jscoverage` program. The `jscoverage-server` program is a simple HTTP server which instruments JavaScript code as it is served; this allows you to execute JavaScript and gather code coverage statistics without a preliminary step of creating instrumented code. The `jscoverage-server` program can either serve files directly from the filesystem or run as a proxy server (with the `--proxy` option), instrumenting JavaScript provided by another web server.
- Using `jscoverage-server`, coverage reports can now be stored to the filesystem.
- JSCoverage now recognizes special JavaScript comments which specify that certain lines of code should be ignored in coverage reports.
- The new `--encoding` option provides better support for different character encodings.
- The JSCoverage user interface is now faster and more responsive.
- The new `--no-highlight` option can be used to disable syntax highlighting (giving better performance for large JavaScript files).
- The build system has been modified so that `make install` only installs the `jscoverage` and `jscoverage-server` executables and their manual pages. (Previous versions installed SpiderMonkey library and executable files, which could conflict with other versions of SpiderMonkey installed on your system.)
- JSCoverage now supports several features beyond those found in the ECMAScript Language Specification, including the following:
  - getters and setters
  - `for each` loops
  - generators and iterators
  - the `let` keyword
  - destructuring assignment
  - array comprehensions
  - expression closures
  - generator expressions
  Use the new `--js-version` option to enable these features.

The GCC C++ compiler (`g++`) is now required to compile JSCoverage. (Previously, only the C compiler was needed.)

Please report any bugs you find using the new bug tracker.
