ocaml-lua
[10-Sep-2012, version
1.0,
Stable]
OCaml-lua provides bindings to the Lua programming language. Lua is a scripting language particularly useful when you need to embed a language in your application.
This project provides the bindings required to embed Lua.

Cadmium
[10-Sep-2007, version
1.0-alpha,
Alpha]

Java port of ocamlrun, runtime support for Cafesterol.
OCamlnat
[22-Nov-2011, version
0.1.0,
Beta]
The ocamlnat project provides a new native code OCaml toplevel ocamlnat, which is mostly compatible to the byte code toplevel ocaml, but up to 100 times faster. It is based on the optimizing native code compiler, the native runtime and an earlier prototype by Alain Frisch. It is build upon Just-In-Time techniques and currently supports Unix-like systems (i.e. Linux, BSD or Mac OS X) running on x86 or x86-64 processors. Support for additional architectures and operating systems is planned, but not yet available.
OCamlScripting
[15-Oct-2007, version
1.0,
Alpha]
OCamlScripting is an implementation of the Java JSR223 Scripting API (this API is defined by the javax.script package) for the Objective Caml language. It thus provides a script engine that allows execution of Objective Caml code snippets in a Java application.

McCarthy
[21-Feb-2006,
Beta]

McCarthy is a simple, first-order functional programming language. The interpreter of this language is also called McCarthy. McCarthy is Turing-complete i.e. it can compute all Turing-computable functions on the integers. It is not suitable for general purpose programming as it offers only an elementary subset of the features found in general purpose programming languages, but it can serve as a model of computation.
Nnjoy
[07-Nov-2005, version
0.2,
Beta]
NJoy is a variant of the concatenative programming language Joy The main difference is that it is enriched with an easy to module system with optionally private declarations.
Only a part of the standard library of Joy is implemented. The interpreter is easy to use, but the builtin functions are poorly documented. The performance of the interpreter (natively compiled and stack traceback switched off) is on par with optimized C implementation of Joy.
