    Eagle Mode

    Eagle Mode

    Zoomable user interface (ZUI) with file manager, file viewers and more

    Eagle Mode is a zoomable user interface (ZUI) with file manager, file viewers, games, and more. This project is about a futuristic style of human-computer interaction, where the user can visit almost everything simply by zooming in. It features a portable C++ toolkit API for developing such ZUIs, and it features the Eagle Mode application, which provides a virtual cosmos with plugin applications. The most important one is the professional file manager with its rich, scriptable command set. It integrates file viewers for most of the common file types, as well as an audio and video player. Furthermore, the virtual cosmos contains a chess game, a netwalk game, a 3D minesweeper game, a multi-function clock, a stock watchlist, some fractals, and a Linux kernel configurator in form of a kernel patch.

    EDITEL

    EDITEL is a screen editor/code generator for GnuCOBOL programmers

    One of the hardest things to do when coding with COBOL is translating a screen design into code. The process may take hours, not to say days. In my old BLIS-COBOL, COBOL 74 and COBOL 80 /85 days (and those last 2 had the SCREEN SECTION which helped a lot !), I recall spending a significant amount of time dedicated to that activity. Time that could be used for more productive activities like coding and resolving bugs, for instance. Having said that, I developed a Screen Editor (similar to a Screen Painter, as some tools may call it) which allows the user to create screen layouts (which includes the use of colors) with delimited fields and respective input masks, and finally generate the SCREEN SECTION code that reflects that layout. All of it automatically - no code needed. The idea came from a program I used to use named EDITEL. I have adapted the concept (it was originally built for BLIS COBOL systems) and created a version that does this for GnuCOBOL and Microfocus COBOL. Enjoy !

    Agar

    Agar

    Cross Platform GUI Toolkit

    Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.

    Mateusz's Saucy Editor

    Mateusz's Saucy Editor

    A simple console-mode text editor

    Mateusz's Saucy Editor (MSEDIT) is a simple editor working in the DOS environment. I decided to write it, because I had been using the Microsoft's EDIT editor for years, without finding any free alternative. Of course, there is plenty of free DOS editors out there, but no one has ever matched my expectations (or should I say, my taste). I guess that's because I had already been "formatted" by the MS editor :-) You will probably notice that MSEDIT is very similar to Microsoft's EDIT. That's a pure coincidence, and there is no connection at all between both of them.
