Sourceprinter

SourcePrinter "formats" the following code

code "x = 10; result = 15" (no newline)
into
"x = 10result = 15"

It also removes all comments from the code, which is not really handy in case you want to use it as a code-formatter.

Testcode:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
SourceBuffer sourceBuffer = new SourceBuffer();
UnicodeEscapingReader unicodeReader = new UnicodeEscapingReader(new StringReader(code),sourceBuffer);
GroovyLexer lexer = new GroovyLexer(unicodeReader);
unicodeReader.setLexer(lexer);
GroovyRecognizer parser = GroovyRecognizer.make(lexer);
parser.setSourceBuffer(sourceBuffer);
String[] tokenNames = parser.getTokenNames();
parser.compilationUnit();
SourcePrinter formatter = new SourcePrinter(new PrintStream(baos), tokenNames, true);
AST ast = parser.getAST();
SourceCodeTraversal traverser = new SourceCodeTraversal(formatter);
traverser.process(ast);
return new String(baos.toByteArray());
