YAPICCC - Yet Another PIC C Compiler - it's a command-line C compiler developed to build programs to Microchip PIC devices. Please visit the project Home Page for more information.
A cross-platform, cross-compiler, cross-CPU C header library for programming with SIMD instruction sets. X86 (MMX/SSE/SSE2) GCC and MSVC, PPC Altivec GCC, WMMX ARM GCC, and software emulated SIMD are supported.
"Web Test Tools" is an open source project which provides tools for different kind of testing such as unit tests (JUnit), and different kinds of tests for applications. Additionaly you can download here good implementation of internet protocols in Java.
C! is a smart preprocessor for C/C++, which helps resolving cumbersomeness and untidiness, bridges between different standards and provides several very powerful extensions to C and C++.
Ruby Inline's 13+ releases has been fully migrated to http://rubyforge.org/projects/rubyinline/ Please go there for more information. It just seems to work better over there. :/ (just click home page above)
wspacegen is an interactive IDE for programing with whitespace (http://compsoc.dur.ac.uk/whitespace/). So it's possible to create .ws code relative easily and debug it as well. But attention, you'll addicted to it (-:
JCom is a bridge library between Java and Com to enable COM object access from Java classes.
Example: Creating an Excel worksheet, or using Visual Basic COM application from a Java application. See also this alternative http://com4j.kohsuke.org/
frCoder is a set of tools used to write, test, and simulate software written for the FIRST Robotics Competition (FRC). frCoder also includes basic libraries of common techniques used in the FRC.
NunniFSMGen generates a FSM (Finite State Machine) in Java, C or C++ starting from a transition table. NunniFSMGen cleanly separates logic from implementation by using a modified version of the state pattern, easing the development process!
deltaFSD is a graphical tool for defining a program by linking the inputs and outputs of functions.
The links created between functions determine the interdependencies within the program and so the sequence in which the functions should be executed.
Lemick is a project to make a programming language similar to those traditional Basic implementations but with all the attributes of the modern programming tool
The bmp2gbtile utility is intended for Gameboy Advance development. The utility will convert one or more .bmp files into a single C or C++ source representation. This source can be used in a GBA project for on-screen sprites or background tiles.
Purpose of this tool is to help in device driver development.
Common part of a device driver is handling registers and memory
mapped structures. Ogham will automatically generate such source
code from more abstract XML-based description of a device.
A full development kit, based on XSCompiler. Multi-platform compiler and IDE, many libraries and examples. Uses an innovative programming language, an improved version of the standard and well-known C/C++.
galsC is a compiler for a new language (based on nesC, which is based on C) to support the TinyGALS (Globally Asynchronous, Locally Synchronous) programming model. This compiler is designed to work with the TinyOS project.
