CSS Compiler

CSS files are stored in a directory structure that mirrors the JavaScript class packages:

+- src/
   +- main/
      +- css/
         +- com/
            +- myapp/
               +- MyClass/
                  |
                  +- MyClass.css
                  +- icon.png
                  +- arrow.png

Pass the CSS compiler a JavaScript file to compile and instead of writing out the contents of the various included JavaScript files, it looks on the filesystem and classpath for CSS files instead.

// If you have a theme, tell the compiler
String theme = null;

// The input file is the page file.
URL inputFile = new URL("file:///path/to/file.js");

// This is the package that holds the page files for my application
String pagePackage = "myapp.page";

// This is where the compiled JavaScript will get written to
OutputStream outputStream = new FileOutputStream(File.createTempFile("foo", "css"));

// These are any base styles that my application needs
String[] includes = new String[] {
    "src/main/webapp/css/reset.css",
    "src/main/webapp/css/common.css"
};

// This is where the compiler should search for source files in addition to the classpath
String[] sourceRoots = new String[] {
    "src/main/javascript"
};

Compiler compiler = new CSSCompiler(theme, includes);
compiler.compile(url, pagePackage, outputStream, sourceRoots);
