CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.
ECL (Embeddable Common-Lisp) is an interpreter of the Common-Lisp language as described in the X3J13 Ansi specification, featuring CLOS (Common-Lisp Object System), conditions, loops, etc, plus a translator to C, which can produce standalone executables. ECL supports the operating systems Linux, FreeBSD, NetBSD, OpenBSD, Solaris and Windows, running on top of the Intel, Sparc, Alpha, PowerPC and ARM processors.
xacc.ide is a opensource IDE aimed at mainly .NET development. It has a code editor written in 100% C# code, which is faster than most commercial offerings.
Blaise is a Lisp dialect (specification and compiler). It's a modern version of Lisp suited for Lisp beginners and modern project development.
CLiCC generates C-executables from Common Lisp application programs.
A lisp system for embedded systems.
a GCC compiler plugin and domain specific language ....
GCC-MELT is a high-level domain specific language to extend the GCC compiler. It provides several features (pattern-matching, first-class dynamically typed values, functional/applicative/object-oriented/reflective programming styles, Lisp-y syntax) MELT can also be used to explore the internal representations used by GCC (Gimple, etc...)
Lushous is an initiative to develop two main Java oriented components for Lush. The first component, JLush, implements inline Java usage in Lush (like CLush does for C). LushJ, the second component, is a Java based implementation of Lush.
OS based on Agent based Security with a new type of split kernel and agents platform.
ThinLisp is a practical dialect of lisp for real world applications. You develop in Common Lisp, you deploy in C. ThinLisp programs are as fast as C, by design. Used for a decade in million line systems.
XINAL Is Not Arc Lisp. XINAL will be a new dialect of Lisp. Whereas Lisp is practically a programmable programming language, XINAL will be written in a subset of itself, and thus will literally be a programmable programming language.
ELCO stands for Embedded Lisp COmpiler or Esdens Lisp COmpiler. The goal is to create a lisp compiler for embedded 32bit architectures. (i.e. ARM) With this compiler you are able to write lisp code on a naked chip. No OS needed.
an embeddable Lisp system that is lightweight, reasonably fast, and highly extensible
