A tutorial on the Sather programming language.
REXX/imc is a Rexx interpreter for Unix. It supports all the standard
instructions and built-in functions, plus a small number of extensions,
and has a partial implementation of the SAA API allowing applications
to call Rexx programs and to register addressing environments, Rexx
functions, and exit handlers.
GCC, the GNU Compiler Collection, supports a number of languages. This
port installs the C, C++, Fortran and Java front ends as gcc5, g++5,
gfortran5, and gcj5, respectively.

Scheme 48 is an implementation of the Scheme programming language as
described in the Revised^5 Report on the Algorithmic Language Scheme.
It is based on a compiler and interpreter for a virtual Scheme
machine. The name derives from our desire to have an implementation
that is simple and lucid enough that it looks as if it were written in
just 48 hours. We don't claim to have reached that stage yet; much
more simplification is necessary.
Scheme 48 is an implementation of the Scheme programming language as described
in the Revised5 Report on the Algorithmic Language Scheme [6]. It is based on
a compiler and interpreter for a virtual Scheme machine. Scheme 48 tries to be
faithful to the Revised5 Scheme Report, providing neither more nor less in the
initial user environment. (This is not to say that more isn't available in
other environments; see below.)
Scheme 48 is under continual development. Please report bugs, especially in
the VM, especially core dumps, to scheme-48-bugs@s48.org. Include the version
number x.yy from the "Welcome to Scheme 48 x.yy" greeting message in your bug
report. It is a goal of this project to produce a bullet-proof system; we want
no bugs and, especially, no crashes.
RegUtil is an implementation of IBM's RexxUtil for Regina. According to
the author, it is not complete; however, it implements a large number of
the RexxUtil functions, and is very useful.
Note that any scripts which load RegUtil must be run with the 'regina'
command, rather than 'rexx'; the latter does not support the use of
external function packages.
Rexx/Wrapper is a tool that wraps Rexx source or tokenised code into an
executable. The Rexx source code can be optionally compressed and encoded to
ensure that the original Rexx code cannot be viewed (unless you have the
original encryption key).
To use Rexx/Wrapper you need two extra bits of software:
1. A supported Rexx interpreter
2. A supported C compiler
Rhino is an open-source implementation of JavaScript written entirely
in Java. It is typically embedded into Java applications to provide
scripting to end users.
Rhino is an implementation of the core language only and doesn't contain
objects or methods for manipulating HTML documents.
Rhino contains
* All the features of JavaScript 1.6
* Allows direct scripting of Java
* A JavaScript shell for executing JavaScript scripts
* A JavaScript compiler to transform JavaScript source files
into Java class files
* A JavaScript debugger for scripts executed with Rhino
Rubinius is an implementation of the Ruby programming language.
The Rubinius bytecode virtual machine is written in C++, incorporating
LLVM to compile bytecode to machine code at runtime. The bytecode compiler
and vast majority of the core classes are written in pure Ruby.
To interact with the rest of the system, the VM provides primitives which can
be attached to methods and invoked. Additionally, FFI provides a direct call
path to most C functions.
Rubinius uses a precise, compacting, generational garbage collector. It
includes a compatible C-API for C extensions written for the standard Ruby
interpreter (often referred to as MRI Matz's Ruby Implementation).
