Question

I’m using FreeMarker to generate java code, but as most of it is dynamically generated it’s difficult to control the code formation.

I want to get code well formatted. Does anyone knows a lib or something like a pretty printer for java code?

Answer 1

I guess i will use Eclipse’s CodeFormatter, just like this guy: http://ssscripting.wordpress.com/2009/06/10/how-to-use-the-eclipse-code-formatter-from-your-code/

UPDATE:
ended up using jastyle ( http://sourceforge.net/projects/jastyle/ ).
here’s an example:

public static String formatJavaCode(String code) throws Exception {
    ASFormatter formatter = new ASFormatter();

    // bug on lib's implementation. reported here: http://barenka.blogspot.com/2009/10/source-code-formatter-library-for-java.html
    code.replace("{", "{\n");

    Reader in = new BufferedReader(new StringReader(code));
    formatter.setJavaStyle();
    in.close();
    return FormatterHelper.format(in,formatter);
}
