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.
CMUCL is a free, high performance implementation of the Common Lisp programming language which runs on most major Unix platforms. It mainly conforms to the ANSI Common Lisp standard. CMUCL provides a sophisticated native code compiler; a powerful foreign function interface; an implementation of CLOS; the Common Lisp Object System; which includes multimethods and a metaobject protocol; a source-level debugger and code profiler; and an Emacs-like editor implemented in Common Lisp. CMUCL is maintained by a team of volunteers collaborating over the Internet, and is mostly in the public domain.
jHepWork (jWork) is an environment for scientific computation, data analysis, and data visualization for scientists, engineers, and students. The program is fully multi-platform (written in Java). Programs can be written in the Java, Jython/Python, and BeanShell scripting languages. Matlab/Octave is supported for symbolic calculations. The program can be used to display data and functions in D and 3D. It comes with a friendly IDE and a code assist.
Java Development Environment for Emacs (JDEE) is an Emacs-based integrated development environment (IDE) for developing Java applications and applets. Features include multiple code browsers, a JPDA-based debugger, method and field completion, template-based and procedure-based code generation, Java source code interpreter, context-sensitive help, and more.
openadaptor is a Java/XML-based software platform which allows for rapid business system integration with little or no custom programming. openadaptor can be loosely classified as EAI (Enterprise Application Integration) software. It is highly extensible and provides many ready-built interface components for JMS, Oracle, Sybase, and TIBCO, as well as data exchange formats such as XML.
se is a screen-oriented version of the classic UNIX text editor ed. The editor implements many of the commands of ed, but instead of being line-oriented, se is screen-oriented. The command syntax is very familiar to users who already know ed. If you get stuck, there is a built-in help system that describes many of the available commands. Many configurable options can be loaded from a .serc file. se can be run interactively or in a script via the included scriptse utility. The editor is portable across many platforms, supporting major Linux and BSD distributions as well as other systems like GNU, Minix, Haiku, OpenSolaris, and Cygwin.
Editkit is a small and modular package, written in C, which extends Terry Loveall's lightweight editX project. Emacs and Wordstar bindings are currently available, and VT100 console or X frontends are provided. Since the binaries are small and require just the basic termcap or X11 libraries, it should be useful for small environments or rescue disks. It should also be easy to embed Editkit as an auxiliary tool in other projects. Still, it can be used as a lightweight clone of emacs with nearly identical basic editing commands and some custom-keys scriptability.
Ersatz Emacs is a very minimal imitation of the famous GNU Emacs editor. Unlike most popular Emacs derivatives, Ersatz strives to use as little system resources as possible and be simple enough for the casual programmer to understand, yet still include all the functionality required for most text editing jobs. Thirteen years ago this was the Public Domain release of MicroEmacs 3.6 as posted to mod.sources.
