Euphoria is a simple, flexible, easy-to-learn programming language. It lets you quickly and easily develop programs for Windows, Linux, FreeBSD, NetbSD, OpenBSD, and Mac OS X. Although Euphoria provides subscript checking, uninitialized variable checking, and numerous other run-time checks, it is extremely fast and has the ability to compile to transparently compile native executables via C code.
MLton is a whole-program optimizing Standard ML compiler. It generates standalone executables with excellent runtime performance, supports the full SML 97 language, and has a complete basis library. It also has a fast C FFI, source-level time and allocation profiling, and many useful libraries.
STklos is a free Scheme System conforming to R5RS. The implementation is based on an ad-hoc Virtual Machine. It can also be compiled as a library, so that one can easily embed it in an application. Its features include an efficient and powerful object system based on CLOS, a simple-to-use module system, implementation of the full tower of numbers defined in R5RS, and easy connection to the GTK+ toolkit. STklos is the successor of STk, a Scheme interpreter tightly connected to the Tk toolkit.
Harbour is a free, cross-platform compiler for the Xbase language. It is designed to be as compatible with CA-Clipper as humanly possible. Harbour ships with full source and makefiles, and combined with one of many C compilers will create executables which run natively on the following platforms: Linux, FreeBSD, DOS, Windows 3.x/9x/NT/W2000, and OS/2.
TinyCOBOL is an effort to bring a free COBOL compiler to Linux. It generates GNU assembler for the i386 Linux platform. A executable binary is then created using the GNU assembler and linker. The project is approaching the first beta release with many statements already implemented.
An almost ISO C compatible C compiler that produces binaries for 6502-based computers. Targets that are supported out of the box are: Apple ][, Atari 8-bit machines, Commodore C64/C128/C16/C116, Commodore Plus/4, Commodore 600/700, GEOS for C64, and Lynx. The package includes a complete suite of assembler development tools (assembler, linker, archiver) which allows mixing of C and assembler code.
MIB Smithy is an application for SNMP and COPS developers, MIB and PIB designers, and Internet-draft authors. It provides a GUI-based environment for designing, editing, and compiling MIB and PIB modules according to the SMIv1, SMIv2, and COPS-PR-SPPI standards. It accelerates the development process by providing an easy-to-use GUI-based environment for developing the specifications without the syntax and formatting concerns of editing the modules by hand. It includes a number of built-in basic SNMP management tools, XML support, and (with MIB Smithy Professional) support for custom compiler output formats.
