TOM is a compiled object-oriented programming language that advocates unplanned reuse of code. To this effect, in TOM a class is defined by its main definition plus any extensions; an extension can add methods, variables, and superclasses to a class, while the class' source is not needed and does not need recompilation, nor is recompilation required for any client code or subclasses. Extensions can even be loaded at run time.
Universal Embedded SQL Compiler (UESQLC) is a compiler that provides a common way for accessing heterogeneous databases. UESQLC is based on Structured Query Language (SQL) as a standard for accessing data. This interface provides maximum interoperability, i.e. a single application can access different SQL Database Management Systems (DBMS) through a common set of embedded SQL code (UESQL). This enables a developer to build and distribute a client/server application without targeting a specific DBMS.
WLA DX is yet another macro assembler that can program the GB-Z80, Z80, 6502, 65c02, 6510, 65816, HuC6280, and SPC-700 CPUs. Included in the package there is a GB-Z80 disassembler and few converters. WLA DX was initially programmed to compile ROM images for Gameboy, but nowadays it can also patch existing ROM images with code, and even compile program files and ROM files for other CPUs like the NES-6502, C64-6510, and SNES's SPC-700.
XBasic is a comprehensive program development environment that integrates a powerful editor, compiler, debugger, function libraries and GuiDesigner into a seamless working environment that encompasses the whole process of creating fast, efficient, reliable, portable 32-bit programs. XBasic is currently available for Linux and Windows 9x/NT.
Yap is a high-performance Prolog compiler developed at LIACC, Universidade do Porto. Its Prolog engine is based on the WAM (Warren Abstract Machine), with several optimizations for better performance, and achieves performance comparable or exceeding that of commercial Prolog systems. Yap is largely compatible with the major Edinburgh Prolog systems, and has been ported to most 32-bit and 64-bit Unix based platforms. A Windows port is also available.
zJSP is an experimental translator from JavaServer Pages (jsp's) to Java. It is designed to be used in conjunction with Sun's Java Servlet Developers Kit (JSDK), version 2.0. It *should* work with any Java Servlet environment compatible with JSDK servlets. zJSP is implemented as a page compiler, translating JSP pages into Java Servlets, which are then run using a Java Servlet environment.
Styx is a scanner/parser generator designed to address some shortcomings of the traditional lex/yacc combination. It has unique features like automatic derivation of depth grammar, production of the derivation tree, including it's C interface, preservation of full source information, pretty printing to faciliate source-source translation, and persistence to aid rapid interpreter writing. It also supports reentrancy. Styx works well under several different OSes, including serveral Unixes, DOS, and Windows.
