jContractor is a 100% pure Java implementation of Design By Contract for the Java language. Contracts are written as methods that follow a simple naming convention. jContractor provides runtime contract checking by instrumenting the bytecode of classes that define contracts. jContractor can either add contract checking code to class files to be executed later, or it can instrument classes at runtime as they are loaded. All contracts are written in standard Java. Mirah (nee Duby) is a new experimental language born out of the JRuby project. In order to make implementing Ruby on the JVM easier and more approachable for Java and Ruby developers alike. Mirah’s design is centered around a few simple principals: Platform-agnostic, Free from concrete decisions about the back-end type system, code generation, or other details are specified by the outward language. This means roughly similar scripts could conceivably compile to any number of type systems and runtimes. In this sense, Mirah is more of a rough coupling of Ruby-like syntax with a pluggable type-inference and compilation pipeline. The JavaFX Script programming language lets you create modern looking applications with sophisticated graphical user interfaces. It was designed from the ground up to make GUI programming easy; its declarative syntax, data binding model, animation support, and built-in visual effects let you accomplish more work with less code, resulting in shorter development cycles and increased productivity. |
