Felix is a programming language with a fully featured purely functional subsystem embedded in a a traditional Algol-like imperative programming system. The system features garbage collection, static typing, parametric polymorphism, overloading, regular expression matching, and a lot more. A scripting harness is used to invoke source files, but fully compiled binary shared libraries are generated, yielding both rapid prototyping and high performance. Seamless binding of C/C++ code makes interfacing existing libraries easy. Control inversion provides language-level cooperative multi-tasking.
repasa is a set of three kind of tools: For creation of contents directly in the XML format of repasa or in other file formats (DocBook and LaTeX) following some conventions, for checking the contents, and for studying the contents and registering progress. The contents can be specified with definitions, classifications for the definitions (possibly along with exercises), and sequences of study. It is especially well suited to organize information according to the current legislation for education in schools of Colombia.
