    AlphaC

    AlphaC

    Intérprete similar al lenguaje C en Español

    AlphaC es un pequeño intérprete similar al lenguaje C en Español, creado en la herramienta Microsoft Visual C++ con fines académicos. El proyecto tiene el objetivo de mostrar el código fuente de un pequeño compilador para ilustrar a los estudiantes las diferentes fases de construcción de un compilador (Análisis Léxico, Análisis Sintáctico y Análisis Semántico). El código está creado de manera bastante elegante de manera que se parece a la sintaxis utilizada en los libros de texto de gramáticas y compiladores. Además el código es corto y fácil de comprender.

    AppM Build Automation

    AppM Build Automation

    Automated software application for constructing and building projects.

    AppM Build Automaiton is an open source and automated software application that is used to construct and build projects on different operating systems and using different development environments. General principles of implementation: -Each project must have a Build Project File, containing the necessary information on the construction of the project. For example, a unique name of the project, dependence on other projects and libraries, methods of construction, etc. Thus, the entire repository should be marked by the project description files to provide unambiguous information on the projects and their dependencies. - AppM Build Automaiton must be able to perform different actions (project construction, external applications launch, file copying, etc.) which are needed to build a -product. - All operations with projects should be carried out on the basis of information that build tool derives from the project description files.
