f2py is a command line tool for binding Python and Fortran code. It scans Fortran 77/90/95 code and generates a Python C/API module that makes it possible to call Fortran routines and to access Fortran data (COMMON blocks and Module data) from Python. No Fortran or C expertise is required for using this tool.
JEL (Java Expressions Library) is a library for evaluating simple single-line expressions in Java. The key feature of JEL is the fact that it is a compiler. The language of JEL expressions resembles the Java Language expressions as close as possible. JEL supports all Java primitive types and classes (even in the form of constants), allows one to call both static and virtual methods of Java classes (with no additinal runtime costs and no wrappers), and performs evaluation of constant subexpressions at a compile time.
JFlex is a flex-like lexer generator for Java with emphasis on speed and full Unicode support. It works as a standalone tool or together with the LALR parser generators CUP and BYacc/J. JFlex has support for some not so usual features like negation in regular expressions and nested input streams. It can also read JLex specifications unchanged.
KernelDriver automates your Windows 2000/NT, Windows Me/98/95 and Linux device driver development by providing you with powerful tools for hardware debugging, driver code generation, and driver debugging. KernelDriver supports PCI / USB / ISA and EISA drivers. KernelDriver for Windows and Linux includes the powerful Driver Wizard. Using the Driver Wizard you can graphically debug your hardware by "peeking" and "poking" at it without writing a single line of code. After your hardware is diagnosed, use the Driver Wizard to generate a complete kernel mode device driver which will drive your hardware.
NASM is an 80x86 assembler designed for portability and modularity. It supports a range of object file formats including Linux a.out and ELF, COFF, Microsoft 16-bit OBJ, Win32/64, and Apple Mach-O. It will also output plain binary files. Its syntax is designed to be simple and easy to understand, similar to Intel's but less complex. It supports all currently known opcodes, and has advanced macro capability. It includes a disassembler as well.
Parse::Yapp provides a set of modules and a frontend to generate Perl OO LALR(1) parsers. It can input clean yacc or bison grammars. The generated parsers are fast, being based, like yacc, on building Deterministic Finite Automata (DFA) and moving through a set of states using Deterministic Push Down Automata (DPDA) derived from the DFA to match the input stream tokens.
The Portable Forth Environment implements the ANSI Standard of the Forth programming language. It is fully written in C, and with gcc the virtual machine can be put into cpu registers. The newer development versions implement a set of modern features including modularization and multithreading. The terminal connection itself can be configured to work in an embedded environment.
