GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
Gnutran is a simple, Emacs-based front-end to a number of machine translation engines available on the Web. It can send emacs buffers to a translation engine, request a translation (e.g. English to Portuguese) and display the result on a new window. GNUTRAN interoperates with emacs-based email agents such as VM-Mail and features a highly configurable interface, allowing easy set up of new translation pairs through Emacs' customization interface.
GOOPS is the object-oriented extension to Guile. Its implementation is derived from STk and Tiny-Clos. It is very close in spirit to CLOS (the Common Lisp Object System) but is adapted for the Scheme language. While GOOPS is not compatible with any of these systems, GOOPS contains a compatibility module which allows for execution of STKlos programs. Briefly stated, the GOOPS extension gives the user a full object oriented system with multiple inheritance and generic functions with multi-method dispatch. Furthermore, the implementation relies on a true meta object protocol, in the spirit of the one defined for CLOS.
GTK Development Environment (GDE) acts as a framework when you are programming. It is not an integrated development environment, but more a tool to manage programming projects. It keeps the user from switching between terminals and editor windows, with a project explorer. Making and running a project can be done with function keys, with commands the user defines.
ics.el is a comint based Emacs major mode for handling the text portion of communications with internet chess servers such as FICS and ICC. It is written in Emacs-Lisp and works best in conjunction with a graphical interface such as Xboard. It handles colour highlighting and "buttonisation" (making certain portions of text active so that, for example, you can challenge opponents with a single mouse click) as well as command recall and editing and automation of commands based on regexps seen in the ICS output, all highly customisable using Emacs lisp.
Infoflex®, a complete 4GL, saves coding drudgery with its many built-in features. Unlike other 4GL's, Infoflex streamlines the design process with a consistent WYSIWYG approach to developing menus screens and reports. Infoflex provides 4GL functionality within a well integrated "c" environment. This unique high-low approach gives you the flexibility of "c" with all the power of 4GL. Infoflex is similar in syntax to Informix. It is also compatible with C-Isam, D-Isam, Netisam, MF Cobol or Integra, and supports UNIX, DOS, or VMS. Infoflex's accounting product, AccountFlex, is a powerful, full-featured accounting utilizing Infoflex 4GL.
