Class Juicer::Minifyer::ClosureCompiler
In: lib/juicer/minifyer/closure_compiler.rb
Parent: Object

Provides an interface to the Closure compiler library using Juicer::Shell::Binary. The Closure compiler library is implemented using Java, and as such Java is required when running this code. Also, the compiler jar file has to be provided.

The Closure Compiler is invoked using the java binary and the compiler jar file.

Providing the Jar file (usually compiler.jar) can be done in several ways. The following directories are searched (in preferred order)

 1. The directory specified by the option :bin_path
 2. The directory specified by the environment variable $CLOSUREC_HOME, if set
 3. Current working directory

For more information on how the Jar is located, see +Juicer::Minify::ClosureCompiler.locate_jar+
