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.
AEditor is a programmer's editor for Windows, Unix, and Mac OS X that relies on the fox toolkit. It can do syntax coloring of Ruby and C++ files. It's easy to change the color theme. Most things are customizable. It is written in Ruby and is carefully unit-tested (it has 421 tests). It is written in only ~5500 lines of code, so it should be easy to grasp and extend.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
Factor is a dynamically-typed stack-based programming language. Factor runs on various OSes and CPU architectures, and provides an optimizing compiler, interactive development environment, powerful collections, higher order programming, continuations, and a growing library of contributed code.
Essential Management is a multi-user project management system for managing intricate and complex information. Its initial purpose was to allow software development teams to create, maintain, track, and store project requirements on a multi-project basis in a multi-user environment. It has now become more abstract in the type of data it can maintain, allowing the easy addition of new data models and other expansions. Information can be stored in any of several database management systems, and can take advantage of a networked DBMS.
epydoc.el is an Emacs LISP program to write Epydoc documentation comments. It supports forrow functions. epydoc-insert-file-comment inserts file comments and @file, @author, and @copyright automatically. epydoc-insert-function-comment inserts function comments and @param/@return automatically. epydoc.el is based on Tom Emerson's doxygen.el.
