OpenScheme is a Scheme interpreter/compiler/debugger conform to the R4RS standard. OpenScheme integrates a lot of interesting features, such as a regular expression parser, object oriented system, CLOS based, console Object Oriented interface, an unified Operating System access, a preemptive timer library that is thread compatible.

OpenScheme includes an interpreter that performs on-flow compilation and a compiler that produces ANSI C compatible with GCC and Visual C++ [(r) Microsoft] compilers. It also includes a command line symbolic debugger. OpenScheme allows to put in the same source file high level Object Oriented code, standard Scheme, C and assembly (that breaks portability). This feature provides an impressive power to the development environment.

OpenScheme is distributed in a single CD that contains both the Windows and the Linux versions, more that 250 pages of documentation in English, plugins sources, the development kit (header files and libraries), the (reusable) installer in source, the JED editor for Linux and Windows written by J.Davis (JED is not part of OpenScheme). The free version can be used for non-profit usage and can be freely distributed. The commercial version allows profits with no-runtime and a technical support is provided by Erian Concept.

In the future, OpenScheme will be linked to Postgres database. In addition, it will have a complete Object Oriented GUI.
