The youtoo compiler/interpreter compiles EuLisp into C-embedded virtual machine code which can be statically or dynamically linked with the virtual machine, the conservative garbage collector, the EuLisp language library and arbitrary other Lisp and foreign code (C, C++, Fortran, Pascal). Resulting stand-alone executables are portable, interoperable and efficient (see The Lisp Performance Page). The language implementation is extended towards a Virtual Multicomputer Architecture (see Denton and VIM Projects). Object serialization and inter-process communication (via Sockets, MPI, Harvest Object Cache) support the migration of arbitrary data and code.
The system reuses ideas from the Oaklisp system written by Barak Perlmutter and Kevin Lang. The meta-object protocol (Telos) was originally implemented in Common Lisp by Russell Bradford. By default, a garbage collector written by Hans Boehm and Alan Demers is used.
[What is EuLisp?] EuLisp is a single-valued dialect of Lisp with the following features: (i) an integrated object system (Telos) with a defined meta-object protocol to enable reflective programming, (ii) a module system and (iii) a simple light-weight process mechanism (threads). The language definition and more information about EuLisp can be found at the EuLisp FAQ page. For an update on the language definition see also EuLisp online definition.
[What is also interesting?] Euscheme is an implementation of EuLisp level 0 which is based on xscheme. ---youtoo is linked to the Denton and VIM projects. ---Multi-threading based on MIT Pthreads will be supported soon. ---The photo above is by Claude Fournier.
