It is implemented in C++ and has a C++ friendly API to implement extension modules. It aims to be a general purpose glue language. It runs on Linux, Windows, and hopefully other Unix systems. Internally, codes are executed on a byte code interpreter. It also has a concurrent garbage collector to utilize multiple processors.
Loro is an open system intended to help beginners learn programming. It uses its own programming language and includes an integrated development environment system focused on first-year students. The language features a "specify, then implement" methodology; you have to specify a task before writing any implementation (algorithm). Specification is an explict, compilable construction to make a contract between suppliers and clients, and can be implemented in either Loro or Java (via BeanShell). The IDE features support for test-driven developing, syntax highlighting, and automatic HTML documentation generation and visualization.
Quila (from Portuguese: "Quila é um Interpretador para Linguagem Algoritmica") is an interpreter for a simple Pascal-like programming language whose keywords and command names are all in Portuguese. It can help novice programmers that speak Portuguese to learn computer programming, because it is easier to learn than a programming language with English keywords and command names.
CExEv is a package of C++ classes intended to be used for evaluation of C-syntax expression strings. It is intended to be as simple as possible, portable, and not dependant on other libraries. The developer can plug in the application specific variable and function space to be used in the evaluation process.
