RJCE enables the editing of any method at runtime, applying the changes to any combination of objects, such as an array, or a complete class. It consists of a compiler, javaprec, and an IDE, Runtime Object Modifier (ROM). javaprec is used to compile programs, enabling runtime editing, and uses both sun.tools.javac and ANLTR for compilation. ROM is a JFrame used for editing methods, browsing classes, and viewing variables at runtime. It also includes an interpreter that runs Java scripts (which circumvent normal language access control) and is run from within any Java program. Aspects are also incorporated into RJCE, to enhance runtime editing.
TCLP is a type checker for Prolog dialects. It is written in SICStus Prolog. Its goal is to statically trap programming errors like illegal arguments used in a call for a predicate or illegally built data structures with respect to a given typing for function symbols or predicates. TCLP is also capable of type inference for user predicates. Supported dialects include ISO-Prolog, GNU-Prolog, and SICStus Prolog.
Continuum is a continuous integration server. It makes sure that software always builds and works as expected. Continuous integration allows software projects to find and identify problems as soon as code is in the source control system. It currently supports building Apache Maven v1 and v2 projects.
