SWIG
A code generator for connecting C/C++ with other programming languages
SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is used with different types of target languages including common scripting languages such as Javascript, Perl, PHP, Python, Tcl and Ruby. The list of supported languages also includes non-scripting languages such as C#, D, Go language, Java, Lua, OCaml, Octave, R and Scilab. Also several interpreted and compiled Scheme implementations (Guile, MzScheme/Racket) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG is typically used to parse C/C++ interfaces and generate the 'glue code' required for the above target languages to call into the C/C++ code. SWIG can also export its parse tree in the form of XML. -

Lexical Analyzer Generator Quex
Generator of lexical analyzers in C and C++. Unicode Supported.
The goal of this project is to provide a generator for lexical analyzers of maximum computational efficiency and maximum range of applications. This includes the support for Unicode (UTF8, UTF16, ...) and a large variety of other encodings directly and via nested converters such as ICU(tm) and IConv. Sophisticated buffer handling allows to operate on plain file streams, on sockets, or manually fed buffer content. 'Ready-to-build' examples explain related concepts and facilitate practical applications. -

4tH compiler
A Forth compiler with a little difference
4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, BASIC interpreter, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment. -

Xsemantics
a DSL for type systems, reduction rules, interpreters for Xtext langs
Xsemantics is a DSL (implemented in Xtext itself) for writing type systems, reduction rules, interpreters (and in general relation rules) for languages implemented in Xtext. It then generates Java code that can be used in your language implemented in Xtext for scoping and validation (it can also generate a validator in Java). -

ImpLib SDK
ImpLib SDK produces custom Import libraries for Windows DLL
ImpLib SDK combines free programming tools for authoring custom import libraries for Windows DLL (32 and 64 bit). The SDK supports advanced features, like cdecl2stdcall conversion, importing by ordinal, removing original thunk, storing symbols from different DLL files in a single import library. The ImpLib SDK is also useful to overcome any legal restrictions when redistributing the import libraries for certain DLL files, like the Microsoft® C++ runtime. The import libraries for the CRT or STL are part of the Windows SDK. Even though the SDK is available for free, redistributing these files is not allowed according to the current license agreements. An alternative is to generate these import libraries using the ImpLib SDK, as it doesn't restrict redistribution. The ImpLib SDK is free even for commercial use and redistribution of any kind, as long as all copyrights are preserved.
