    Lib CONIO (conio_am.h) GCC C++

    Lib CONIO (conio_am.h) GCC C++

    Library CONIO GCC/Clang C++ (other compilers) for Windows and Linux

    Version 8.2.14.26.09 RC [2017-2026] - Fully ported library. September 27, 2026. This project presents a clone 100% of the Borland Turbo C/C++ or Embarcadero C++ library "conio" (https://l1nq.com/tOsMbeb) for the GCC/Clang compiler, more precisely for the C++ language in Windows, Linux, and Mac OS operating systems. Because all functions are defined within the header file itself, the installation is simple. Just place the header file "conio_am.h" (CONsole Input Output Advanced Method) inside the GCC includes directory. Or keep the file "conio_am.h" in the same location where the source programs will be compiled. For more libraries, go to https://sourceforge.net/u/augustomanzano/profile.

    Python vipera

    Python vipera

    vipera is an application designer for Python

    vipera is a designer of applications for the programming language Python. It has two main objectives: 1) The design of an application from an educative point of view, paying special attention to the documentation and design of classes. 2) The automatic generation of base code for software projects. vipera is a combination of basic tools for the design of applications in the early stages of development, allowing the creation of modules (libraries) and definition of their basic characteristics, such as classes, functions, records, constants and import modules. The design of classes is done graphically, by means of a code similar to UML. It includes an inverse engineering option, that is, from Python scripts, classes and relationships are identified and represented graphically.
