Profligacy: Easier Swing GUI layouts with JRuby
Profligacy is a new library by *** ****, the mastermind behind Mongrel:
Profligacy is a JRuby library that makes building Swing Graphical User Interface much easier than with raw code. It’s not a builder as with many other projects, but instead a simple Ruby way to structure the UI for the 80% common cases you’ll encounter.
Profligacy features some clever magic, such as LEL, a "Layout Expression Language" that lets you build layouts from basic ASCII representations.
