JavaStyle
public class JavaStyle extends MatchingTask (Code)

Task for formatting Java source code. This task utilises the PrettyPrinter code in the JRefactory code produced by Chris Sequin . This library can be found at http://users.snip.net/~aseguin/chrissoft.html .

The current implementation is very simple. I am implemented it as quickly as possible to make it available for others to be able to improve upon!

The task takes only a "file" attribute or an embedded fileset. It contains no other attributes at present, as all formatting controls are read from the default pretty printer preferences file which is stored in a ".Refactory" directory in your home directory. If no such file exists the first time this task is run, a default file is generated automatically.

Features that would be well worth implementing include: adding attributes to control all of the formatting features of the PrettyPrinter, and removing any reliance on an external preference file; allowing the formatted source files to be saved into a different location than the originals.
