guff is a ruby gem containing classes that let you produce nicely formatted Java code. Its intended to be used by code generation scripts that eliminate a lot of the ‘guff’ that often ends up being written on Java projects. One example of this is the javatestingguff project, which generates java classes that provide fluent interfaces to configure mock objects.
I am the only developer right now.
Its beta quality, used in a couple of commercial projects.
Its not used by any external parties to my knowledge, but has been downloaded a few times from rubyforge :-)
